Instead, attempt to pacify GCC 13 with code that relies on undefined but portable-in-practice behavior that GCC 13 does not complain about.

(update-copyright): Use it. 2022-12-28 Paul Eggert assert-h: port static_assert to strict C99 * lib/verify.h (_GL_VERIFY): Port MSVC hack back to C99. Problem found when testing bleeding-edge gzip on IBM XL C for AIX, V12.1 (5765-J02, 5725-C72), which complained ‘"malloca.c", line 42.56: 1506-041 (E) The invocation of macro _Static_assert contains fewer arguments than are required by the macro definition.’ This diagnostic is valid because C99 requires that if you #define _Static_assert(R, ...) you must call _Static_assert with at least two arguments. I found a similar problem with Sun C 5.9 SunOS_sparc Patch 124867-12 2009/11/22. 2022-12-27 Paul Eggert file-has-acl: fix recently-introduced NFSv4 bug * lib/file-has-acl.c (acl_nfs4_nontrivial): Fix off-by-one error when rounding WHOLEN up to next multiple of 4. Pacify GCC 12.2.1 -Wcast-align. Add --pull, --gen options to build-aux/bootstrap This supports a single bootstrap script with --pull and --gen options, as an alternative to separate autogen.sh and autopull.sh and bootstrap-funclib.sh auxiliary files. * top/bootstrap: With --version, also output library version. Support update of package that has only the bootstrap script, and not the other three files. Support packages with just 'bootstrap' * top/bootstrap: With --version, also output library version. Support update of package that has only the bootstrap script, and not the other three files. * top/bootstrap-funclib.sh (scriptlibversion): Rename from scriptversion. All uses changed. This way we can distinguish script from script library versions. (upgrade_bootstrap): If the package currently has only the bootstrap script, just update that. Bootstrap with functions, not scripts * top/bootstrap: Use autopull and autogen functions, not shell scripts. This lets build-aux/bootstrap become a standalone script. It does not change the behavior of top/bootstrap, except for minor rewording of disagnostics. Make autopull a shell function too This does not change behavior. It is helpful for future changes. * top/autopull.sh: Call autopull to do the actual work. (usage, download_po_files, update_po_files): Move to top/bootstrap-funclib.sh. * top/bootstrap-funclib.sh (autopull_usage): Rename from ‘usage’. (autopull): New function, containing the top level of the old top/autopull.sh. Make autogen a shell function too This does not change behavior. It is helpful for future changes. * top/autogen.sh: Call autogen to do the actual work. (usage, version_controlled_file, gitignore_entries, insert_if_absent): (insert_vc_ignore, symlink_to_dir): Move to top/bootstrap-funclib.sh. * top/bootstrap-funclib.sh (autogen_usage): Rename from ‘usage’.

Miller in: https://lists.gnu.org/r/autoconf/2022-12/msg00001.html * m4/stdbool.m4 (AC_CHECK_HEADER_STDBOOL): Sync from Autoconf master. 2022-12-26 Bruno Haible ctime: Mark as deprecated, not obsolete. (Regression 2022-12-21.) * modules/ctime (Status): Remove. (Notice): Say that it is deprecated, not obsolete. 2022-12-25 Paul Eggert largefile: sync from Autoconf master * m4/largefile.m4 (gl_SET_LARGEFILE_SOURCE): Test whether AC_SYS_YEAR2038 is defined when this macro is defined, not when it is used, as we now define AC_SYS_YEAR2038 later. (_AC_SYS_LARGEFILE_MACRO_VALUE): Remove. (_AC_SYS_YEAR2038_TEST_CODE, _AC_SYS_YEAR2038_OPTIONS) (_AC_SYS_YEAR2038_PROBE, _AC_SYS_YEAR2038_ENABLE) (_AC_SYS_YEAR2038_OPT_IN, AC_SYS_YEAR2038) (_AC_SYS_LARGEFILE_TEST_CODE, _AC_SYS_LARGEFILE_OPTIONS) (_AC_SYS_LARGEFILE_PROBE, _AC_SYS_LARGEFILE_ENABLE): New macros. (AC_SYS_LARGEFILE): Use them. * m4/year2038.m4: Remove. All mentions removed. * modules/largefile, modules/year2038 (configure.ac-early): Do not require gl_YEAR2038_EARLY. * modules/year2038 (Depends-on): Depend on largefile. (configure.ac): Require AC_SYS_YEAR2038, not gl_YEAR2038. 2022-12-24 Paul Eggert extensions: enable some C23 Annex F functions * m4/extensions.m4 (AC_USE_SYSTEM_EXTENSIONS): Also define __STDC_WANT_IEC_60559_EXT__, for C23 Annex F functions like totalorder. This syncs from Autoconf master. stdnoreturn: deprecate C23 says is obsolescent, so deprecate the stdnoreturn module. I don't think it was being used anyway as it had too many problems. * modules/stdnoreturn: Mark as obsolete. 2022-12-23 Paul Eggert file-has-acl: improve recent NFSv4 support This fixes a link failure with emacsclient on GNU/Linux. This program wants file_has_acl but none of the other ACL primitives, so it doesn’t link acl-internal.o; this way it doesn’t need to link with -lacl. While I was at it I reviewed the recent changes, fixed some unlikely overflow bugs, and adjusted to GNU style. * doc/acl-nfsv4.txt: Remove. Its contents are now in a comment in lib/file-has-acl.c. * lib/acl-internal.c, lib/acl-internal.h: Move recent changes relating to acl_nfs4_nontrivial to lib/file-has-acl.c, so that there is no trouble linking programs that need only file_has_acl. * lib/file-has-acl.c (acl_nfs4_nontrivial): Move here from lib/acl-internal.c, so that we needn't link -lacl in programs that want only file_has_acl, such as emacsclient. Do not assume a char buffer is aligned for uint32_t. Check more carefully for buffer read overrun. Allow up to 6 ACEs, since other code does; but check that they’re distinct. Avoid integer overflow. Use memcmp rather than strncmp to compare memory blocks. (file_has_acl): Preserve initial errno instead of setting to 0. Allocate a bit more room for trivial ACL buffer. Use EINVAL for botchedk NFSv4 ACLs (which shouldn’t happen). 2022-12-22 Paul Eggert posix_spawnp-tests: fix filename typo Problem reported for GNU m4 by Mitchell Dorrell in: https://lists.gnu.org/r/bug-m4/2022-12/msg00000.html * tests/test-posix_spawnp-script.c (DATA_FILENAME): Fix typo in file name that caused race with test-posix_spawn-script.c. 2022-12-22 Ondrej Valousek file-has-acl: Basic support for checking NFSv4 ACLs in Linux. * lib/acl-internal.h (acl_nfs4_nontrivial): New declaration. * lib/acl-internal.c (acl_nfs4_nontrivial): New function. * lib/file-has-acl.c: Include . (XATTR_NAME_NFSV4_ACL, TRIVIAL_NFS4_ACL_MAX_LENGTH): New macros. (file_has_acl): Test for NFSv4 ACLs. * doc/acl-nfsv4.txt: New file. 2022-12-21 Paul Eggert Port __has_c_attribute to strict C23 * m4/gnulib-common.m4 (_GL_HAS_C_ATTRIBUTE): Remove, as C23 says behavior is undefined if __has_c_attribute appears anywhere other than at the top level of an #if or #ifdef. All uses replaced by wordier invocations of __has_c_attribute. asctime, ctime: deprecate C23 deprecates asctime and ctime, so deprecate them in Gnulib too. * NEWS, doc/posix-functions/asctime.texi: * doc/posix-functions/ctime.texi: Mention this. * lib/time.in.h (ctime): Deprecate any ctime replacement. * modules/ctime: Now obsolete. 2022-12-17 Paul Eggert memset_explicit: port to older MS-Windows * lib/memset_explicit.c (memset_explicit): Remove special case for C==0 and MS-Windows. The code isn’t needed for correctness and it’s more trouble than it’s worth as it prevents this module from being used with GNU Emacs, which wants to port to MS-Windows versions so old that they lack SecureZeroMemory. 2022-12-09 Bruno Haible Update users.txt. * users.txt: Add lbzip2. 2022-12-09 Paul Eggert fts: make debug version compilable again This fixes things in what I hope is a better way than the fd-only approach proposed by Kamil Dudka here: https://lists.gnu.org/archive/html/bug-gnulib/2018-03/msg00079.html https://lists.gnu.org/archive/html/bug-gnulib/2018-03/msg00080.html * lib/fts.c (GNULIB_FTS_DEBUG): Rename from FTS_DEBUG, to avoid collision with coreutils symbol. Do not include (not needed, since we include ) or "getcwdat.h" (no longer exists). (fd_ring_check, fd_ring_print): Add forward decls. (struct devino): New type. (PRINT_DEVINO): New macro. (getdevino): New static function. (fd_ring_print): Do nothing if not debugging. (fd_ring_print, fd_ring_check): Use getdevino instead of getcwdat. The output isn’t as good, but at least it compiles and runs. 2022-12-07 Paul Eggert verify: update __STDC_VERSION__ as per C23 This shouldn’t affect anything; it’s merely a refactoring. * lib/verify.h (_GL_HAVE__STATIC_ASSERT1): Require __STDC_VERSION__ to be at least 202311, instead of at least 202000. The latter number was put in in 2019 because we didn’t yet know C23’s __STDC_VERSION__ value. 2022-12-06 Paul Eggert fts: fix race + mishandling of fstatat failure I hope this fixes a Luke Dashjr coreutils bug report about ext4 ramdisks; see “9.1: du Aborted (corrupt filesystem)” . * lib/fts.c (fts_build): Fix two bugs. First, fts_stat was being called without checking its return value, causing a later abort. Second, there was a race between opening a directory and statting it, fixed by using fstat on the file descriptor rather than fstatat on the directory name. fts: omit goto break_without_closedir * lib/fts.c (fts_build): Refactor to omit goto. fts: clarify ISSET * lib/fts.c (ISSET): Refactor to clarify boolean usage. 2022-12-05 Bruno Haible argp: Correct documentation.

Mention another source of problems with the _OVERFLOW macros. 2022-10-10 Paul Eggert tests: prefer stdckdint to intprops * modules/chown-tests, modules/fchownat-tests: * modules/fdutimensat-tests, modules/futimens-tests: * modules/lchown-tests, modules/stat-time-tests: * modules/utime-tests, modules/utimens-tests: * modules/utimensat-tests: (Depends on): Depend on stdckint, not intprops. * tests/nap.h: Include stdckdint.h, not intprops.h. All macro uses changed. stat-time: prefer stdckdint to intprops * lib/stat-time.h: Include stdckdint.h instead of intprops.h. (stat_time_normalize): Use ckd_add instead of INT_ADD_WRAPV. * modules/stat-time (Depends-on): Depend on stdckdint, not intprops. xalloc: remove stray includes + dependencies These used to be needed, but are not needed now. * lib/xalloc.h: Do not include stdlib.h. [GNULIB_XALLOC]: Do not include "intprops.h". * lib/xmalloc.c: Include stdint.h here instead, for SIZE_MAX. * modules/xalloc-die, modules/xvasprintf (Depends-on): Remove stdint. 2022-09-30 Paul Eggert assert-h: suppress Apple clang 13 false alarms * m4/assert_h.m4 (gl_ASSERT_H): Suppress bogus warnings from Apple clang 13 (clang-1300.0.29.30). Problem privately reported by Mattias Engdegård for GNU Emacs. 2022-09-26 Daiki Ueno largefile: fix detection of time_t size on mingw32 * modules/largefile (configure.ac-early): Ensure gl_YEAR2038_EARLY is invoked before gl_YEAR2038_BODY. 2022-09-25 Paul Eggert fts: fix errno handling if dirfd fails * lib/fts.c (fts_build): Use proper errno if dirfd failed. Although I don’t know of any platform where dirfd can fail here, we might as well get it right. 2022-09-25 Bruno Haible stdbool: Mostly revert last patch. * m4/c-bool.m4 (gl_C_BOOL): If stdbool.h does not exist, just err out. * modules/stdbool (Files): Remove m4/stdbool.m4. 2022-09-24 Bruno Haible stdbool: Don't #include a gnulib-generated stdbool.h from config.h. * m4/c-bool.m4 (gl_C_BOOL): Check for stdbool.h and for _Bool. If stdbool.h does not exist, don't #include but instead put the substitute code into config.h. * modules/stdbool (Files): Add m4/stdbool.m4. 2022-09-24 Bruno Haible stdalign: Don't #include a gnulib-generated stdalign.h from config.h. * m4/stdalign.m4 (gl_STDALIGN_H): Check for stdalign.h. If it does not exist, don't #include but instead put the substitute code into config.h. 2022-09-24 Bruno Haible stdalign: Fix compilation error with MSVC in C++ mode. * lib/stdalign.in.h: Treat MSVC in C++ mode like C++11 compliant compilers. * tests/test-stdalign-c++.cc: Include some other header files. stdalign: Avoid namespace pollution. * lib/stdalign.in.h (_GL_STDALIGN_NEEDS_STDDEF): New macro. Include only when needed. 2022-09-23 Simon Josefsson warnings, manywarnings: Doc fixes. * doc/manywarnings.texi (manywarnings): Improve usage instruction. Start list of comments on particular warning flags, based on comment from Paul Eggert . * doc/warnings.texi (warnings): Mention that it is often used with manywarnings. 2022-09-21 Paul Eggert assert-h: suppress clang false alarms Suppress scads of annoying warnings from clang version 14.0.5 (Fedora 14.0.5-1.fc36) of the form "warning: '_Static_assert' with no message is a C2x extension [-Wc2x-extensions]", by refusing to use single-arg static_assert with older clang. * m4/assert_h.m4 (gl_ASSERT_H): Turn -Wc2x-extensions from a warning into an error when testing static_assert, so that the annoying diagnostic causes the test to fail, which causes assert.h to be replaced in a way that suppresses the diagnostic during the real build. 2022-09-20 Bruno Haible Add another helper script for creating testdirs. * all-modules: New file, based on posix-modules. 2022-09-20 Bruno Haible snippet/warn-on-use: Don't cause wrong AC_CHECK_DECL results with clang. * m4/warn-on-use.m4 (gl_WARN_ON_USE_PREPARE): Use the clang command-line option that disables implicit built-in function declarations in clang. 2022-09-19 Bruno Haible stdbool, stdbool-c99 tests: Fix compilation error with clang/MSVC. * tests/test-stdbool.c (WORKING_BOOL): Define to 0 on compilers that define _MSC_VER. 2022-09-18 Paul Eggert stdbool: omit ‘#undef true’ This is mostly just simplification. * m4/c-bool.m4 (gl_C_BOOL): Test all preprocessors when !HAVE_C_BOOL, not merely __SUNPRO_CC. Use the slightly more-elegant ‘!true’ instead of ‘true == 1’; this shouldn’t matter in practice and if it does matter we want to know about it anyway. Remove an unnecessary ‘#undef true’ that is simply commented out by ‘configure’; again, if true is already #defined to be 0 the system is so messed up we want to know about it anyway. 2022-09-18 Bruno Haible stdbool: Ensure that 'true' can be used in the preprocessor. * m4/c-bool.m4 (gl_C_BOOL): With Sun C++, redefine 'true' if it does not evaluate to 1 in the preprocessor. stdbool-c99: Ensure that 'true' can be used in the preprocessor. * lib/stdbool.in.h (true): Redefine if it does not evaluate to 1 in the preprocessor. 2022-09-18 Bruno Haible uni{case,ctype,gbrk,str}/base: Fix installed .h file (regr. 2022-09-10). * lib/unicase.in.h: Do include . * lib/unictype.in.h: Likewise. * lib/unigbrk.in.h: Likewise. * lib/unistr.in.h: Likewise. 2022-09-18 Bruno Haible signal: Fix a C++ compilation error due to sched_yield on OpenBSD 6.0. * lib/signal.in.h: On OpenBSD, include . Don't include on OpenBSD ≥ 5.1. 2022-09-17 Paul Eggert explicit_bzero-tests: robustify a bit This is mostly to suppress GCC warnings, though I suppose it might also improve the test. * tests/test-explicit_bzero.c: Do not ignore -Wmaybe-uninitialized, as this warning should no longer be generated given the other changes. (test_heap): ASSERT that malloc succeeds, to suppress any GCC warning about relying on malloc succeeding. Declare addr to be volatile, so that GCC does not deduce that it is heapbuf in disguise and diagnose using it after freeing it. (do_secret_stuff): Declare more things to be volatile, to avoid optimizations that might disturb the stack and/or mess up the test in other ways. Pass last_stackbuf address as a parameter rather than having last_stackbuf be static, to avoid GCC warning about assigning address of a local to a static; all callers changed. 2022-09-17 Bruno Haible wchar: Fix compilation errors in C++ mode on Solaris 11.3. * lib/wchar.in.h (wcsnlen, wcpcpy, wcpncpy, wcscasecmp, wcsncasecmp, wcsdup): Force declaration in C++ mode on Solaris (which does not declare these functions in the global namespace). 2022-09-17 Bruno Haible swab: Fix compilation error with Sun C++ on Solaris 11.3. * lib/unistd.in.h (swab): For the C++ declaration, under Solaris 11 but not under Solaris 10, test also __XOPEN_OR_POSIX. 2022-09-17 Bruno Haible time C++ tests: Fix link error on CentOS 5. * modules/time-c++-tests (Makefile.am): Link test-time-c++ against $(LIB_CLOCK_GETTIME). 2022-09-14 Bruno Haible time: Fix compilation errors with clang/MSVC. * m4/time_h.m4 (gl_TIME_H): Test whether asctime_r and ctime_r are declared. * lib/time.in.h (asctime_r, ctime_r): Skip _GL_WARN_ON_USE invocations when these functions are not declared. 2022-09-14 Bruno Haible verify: Avoid syntax error due to static_assert with clang in C++ mode. * lib/verify.h (static_assert): Don't define in clang C++ 6 or newer. * m4/assert_h.m4 (gl_ASSERT_H): If we don't need to define static_assert with clang in C++ mode, don't include . 2022-09-14 Paul Eggert assert-h: work around include confusion * m4/assert_h.m4 (gl_ASSERT_H): Arrange for to not include if assert is already defined. This works around bugs in packages that mistakenly include after including (typically due to double-inclusion of ). Found in coreutils, which I plan to fix. stdbool: depend on C99 Record that stdbool depends on C99 these days. This matters only for ancient compilers that need special flags to support C99 features. * modules/stdbool (Depends-on): Add c99. 2022-09-14 Bruno Haible verify: Avoid syntax error due to static_assert with MSVC 14 in C++. * lib/verify.h (static_assert): For MSVC in C++ mode, use a definition that supports both the two-arguments and the one-argument syntax. 2022-09-14 Bruno Haible posix_spawn-* tests: Fix test failure on mingw when libtool is in use. * tests/test-posix_spawn-inherit0.c (CHILD_PROGRAM_FILENAME): Add the EXEEXT suffix. * tests/test-posix_spawn-inherit1.c (CHILD_PROGRAM_FILENAME): Likewise. * tests/test-posix_spawn-open1.c (CHILD_PROGRAM_FILENAME): Likewise. * tests/test-posix_spawn-open2.c (CHILD_PROGRAM_FILENAME): Likewise. 2022-09-14 Bruno Haible verify: Avoid syntax error due to static_assert with MSVC 14. * lib/verify.h (_Static_assert): Pass only the first argument to _GL_VERIFY. 2022-09-13 Paul Eggert verify: treat GNU C++ 6 like recent C++ * m4/assert_h.m4 (gl_ASSERT_H): If we check __cpp_static_assert < 201411, also check __GNUG__ < 6, for consistency with the previous change. 2022-09-13 Bruno Haible verify: Avoid syntax error due to static_assert with GNU C++ 6.x. * lib/verify.h (static_assert): Don't define in GNU C++ 6 or newer. 2022-09-13 Paul Eggert stdalign: prefer to not include * lib/alignalloc.c, lib/argp-parse.c, lib/fts.c, lib/md4.c, lib/md5.c: * lib/rawmemchr.c, lib/sha1.c, lib/sha256.c, lib/sha512.c, lib/sm3.c: * lib/sys_socket.in.h: In C23, is a no-op, so don’t include it. stdalign: alignas and alignof are C23 keywords * m4/stdalign.m4 (gl_STDALIGN_H): Check also whether alignas and alignof are keywords and so don’t need stdalign.h, and define HAVE_C_ALIGNASOF if so. If not, arrange for config.h to #define alignas and alignof by including . * modules/stdalign: No need to include . * tests/test-stdalign.c: Do not include stdalign.h. assert-h: prefer to ‘verify’ Where it’s easy, prefer ‘static_assert’ to ‘verify’, as this simplifies the source by removing the need to include verify.h.

If not, arrange for config.h to #define static_assert by including , and then do "#undef assert" so that the assert macro still needs an explicit include. This should be safe even on very old hosts, as assert.h has been re-includable for decades. * tests/tests-assert.c: New test. * modules/assert-h-tests (Files, Makefile.am): Add it. 2022-09-13 Bruno Haible Prefer talking about alignas than _Alignas. * m4/gnulib-common.m4 (gl_COMMON_BODY): Don't mention _Alignas in a comment. * m4/stdalign.m4 (gl_STDALIGN_H): Likewise. 2022-09-13 Paul Eggert stdalign-tests: port to C23 * tests/test-stdalign.c: Do not test __alignas_is_defined, _Alignof, or _Alignas as they are obsolescent. Do not use __alignas_is_defined in C23 or later (or C++11 or later), as it’s removed in C23. 2022-09-12 Bruno Haible supersede: Avoid a failure when writing to /dev/null in Solaris zones. * lib/supersede.c (open_supersede): Treat EACCES (seen on Solaris 11.3) like EINVAL (seen on Illumos). 2022-09-11 Paul Eggert maint: avoid unportable ERE \} * top/maint.mk (sc_copyright_check): Avoid unportable use of \} in ERE. verify: improve maint check * top/maint.mk (sc_prohibit_verify_without_use): Adjust re to match verify.h. verify: port better to C23 * lib/verify.h (_GL_VERIFY, static_assert): If C23, use static_assert keyword; no macro. This should simplify diagnostics and debugging. 2022-09-10 Bruno Haible pipe-filter-gi: Fix test failure on native Windows. * lib/pipe-filter-aux.h (write): Redefine on native Windows. 2022-09-10 Bruno Haible stdbool C++ tests: Fix compilation error with MSVC14 (regr. from today). * tests/test-stdbool-c++.cc (s): Choose field names that are not type names. Reorganize C++ tests for stdbool and stdbool-c99. * tests/test-stdbool-c++.cc: Don't include if TEST_STDBOOL_H is not defined. Add a couple of simple tests, from test-stdbool.c. * tests/test-stdbool-c99-c++.cc: New file. * modules/stdbool-c99-c++-tests: New file, based on modules/stdbool-c++-tests. * modules/stdbool-c99-tests (Depends-on): Add stdbool-c99-c++-tests.

newer. 2022-09-10 Bruno Haible uchar: Work around error in C++ mode on AIX 7.2 with xlclang. * lib/uchar.in.h (char16_t, char32_t): On AIX with xlclang++, define these as macros. * doc/posix-headers/uchar.texi: Document the AIX + xlclang++ bug. 2022-09-10 Paul Eggert Rely on new stdbool behavior Prefer the C23 style to the C99 style, since the stdbool module now supports C23. *

Suggested by Bruno Haible in: https://lists.gnu.org/r/bug-gnulib/2022-08/msg00077.html I plan to propose a corresponding patch to glibc. 2022-08-22 Paul Eggert tempname: don't lose entropy in seed * lib/tempname.c (random_bits): Don't lose entropy in S in the rare case where where the template has more than 10 Xs. From a suggestion by Bruno Haible in: https://bugs.gnu.org/57129#149 tempname: fix multithreading, ASLR leak etc. Fix problems with tempname and multithreading, entropy loss, and missing clock data (this last on non-GNU platforms). See analysis by Bruno Haible in: https://bugs.gnu.org/57129#149 While looking into this, I noticed that tempname can leak info derived from ASLR into publicly-visible file names, which is a no-no. Fix that too. * lib/tempname.c: Don't include stdalign.h. (HAS_CLOCK_ENTROPY): Remove. (mix_random_values): New function. (random_bits): Use it. Args are now new value address and old value, and this function now returns a success indicator. Omit old USE_GETRANDOM argument: always try getrandom now, as there is no good reason not to now that GRND_NONBLOCK is used. Caller changed. Use CLOCK_REALTIME for for ersatz entropy, as CLOCK_MONOTONIC doesn't work on some platforms. Also, mix in ersatz entropy from tv_sec and from clock (). (try_tempname_len): Do not mix in ASLR-based entropy, as the result is published to the world and ASLR should be private. Do not try to use a static var as that has issues if multithreaded. Instead, simply generate new random bits. Worry about bias only with high-quality random bits. * modules/tempname (Depends-on): Do not depend on stdalign. tempname: merge 64-bit time_t fix from glibc This merges glibc commit 52a5fe70a2c77935afe807fb6e904e512ddd894e "Use 64 bit time_t stat internally". * lib/tempname.c (struct_stat64) [_LIBC]: Use struct __stat64_t64. (__lstat64_time64) [!_LIBC]: Rename from __lstat64. All uses changed. (direxists): Use __stat64_time64 instead of __stat64. 2022-08-16 Bruno Haible tempname: Add more tests. Based on scenario described by Eli Zaretskii in . * tests/test-tempname.c (main): Add another test. * modules/tempname-tests (Status): Mark the test as unportable. 2022-08-16 Paul Eggert tempname: generate better names for MinGW Emacs On MinGW, GNU Emacs disables clock_gettime, which reliably breaks some of gen_tempname’s optimistic callers. Work around the problem by making the generated names less predictable. We don’t need cryptographic randomness here, just enough unpredictability to keep Emacs happy most of the time. * lib/tempname.c (HAS_CLOCK_ENTROPY): New macro. (random_bits): Use it. (try_tempname_len): On systems lacking clock entropy, maintain state so that gen_filename generates less-predictable names on successive successful calls. 2022-08-16 Simon Josefsson maintainer-makefile: Check for incorrect DISTCHECK_CONFIGURE_FLAGS usage. * top/maint.mk (sc_makefile_DISTCHECK_CONFIGURE_FLAGS): Add. 2022-08-16 Bruno Haible tempname: Add tests. * tests/test-tempname.c: New file. * modules/tempname-tests: New file. 2022-08-16 Simon Josefsson pmccabe2html: Doc fix. * build-aux/pmccabe2html: Don't use reserved _SOURCES namespace. Use AM_V_GEN. Use LC_ALL=C. 2022-08-15 Bruno Haible stdbool: Drop old BeOS support that gets in the way of ISO C 23 support. * lib/stdbool.in.h: Don't include . 2022-08-15 Bruno Haible tempname: Fix a comment. * lib/tempname.c (try_tempname_len): Use of entropy makes the function more, not less, secure. 2022-08-15 Paul Eggert tempname: remove incorrect comment * lib/tempname.c, lib/tempname.h: Remove incorrect comment, as the names are not necessarily hard to predict (Bug#57129). 2022-08-14 Simon Josefsson bootstrap.conf: Use proper shell marker for Emacs. * build-aux/bootstrap.conf: Add it. 2022-08-13 Paul Eggert stdbool: port to C23 * m4/stdbool.m4 (AC_CHECK_HEADER_STDBOOL): Copy from bleeding-edge Autoconf. Define only if Autoconf 2.71 and earlier. * tests/test-stdbool.c (bool, false, true) (__bool_true_false_are_defined): Do not require these to be defined. C23 still requires __bool_true_false_are_defined but marks it as obsolescent, and it’s no longer worth testing. (WORKING_BOOL): New macro, which also tests __STDC_VERSION__. Use it in tests for working bool. Test for bool instead of for _Bool, which C23 says is obsolescent. 2022-08-13 Bruno Haible gnulib-tool.py: Fix some code generation details. * pygnulib/GLEmiter.py: Don't produce Windows CR-LFs on Windows. (GLEmiter.po_Makevars): Emit a definition of top_builddir, not top_subdir. (GLEmiter.po_POTFILES_in): Fix result when sourcebase is 'tests' or something like that. (GLEmiter.initmacro_start): Add two more newlines (mistake from 2021-04-11). gnulib-tool.py: Reduce code duplication. * pygnulib/constants.py (relinverse): New function. * pygnulib/GLEmiter.py (GLEmiter.po_Makevars, GLEmiter.tests_Makefile_am): Use it. * pygnulib/GLTestDir.py (GLTestDir.execute): Likewise. 2022-08-12 Marc Nieper-Wißkirchen hamt: fix technically undefined behavior Bug reported by Bruno Haible in . * lib/hamt.c (entry_insert): Remove technically undefined behavior when shifting an integer of N bits by N or more bits. 2022-08-10 Paul Eggert stdckdint: fix dependency * modules/stdckdint (Depends-on): Add stdbool. Reported by Bruno Haible. maint: parenthesize macro definiens * lib/intprops.h (INT_ADD_OK, INT_SUBTRACT_OK, INT_MULTIPLY_OK): * lib/pipe-filter-ii.c (GetLastError): * lib/thread-optim.h (gl_multithreaded): Parenthesize function-like macro definiens beginning with a unary operator; needed for weird invocations like ‘m (...)[p]’. 2022-08-09 Paul Eggert stdckdint: prefer to intprops when easy stdckdint.h is part of draft C23 and therefore is more likely to be familiar to programmers in the future, so prefer it to intprops.h in files that don’t need non-_WRAPV intprops.h macros. * lib/alignalloc.c, lib/backupfile.c, lib/fnmatch.c, lib/fnmatch_loop.c: * lib/group-member.c, lib/malloca.c, lib/posixtm.c, lib/reallocarray.c: * lib/xmalloc.c: For files that can use stdckdint.h just as easily as intprops.h, include the former instead of the latter, and use the former’s ckd_* macros instead of the latter’s *_WRAPV macros. * modules/alignalloc, modules/backup-rename, modules/backupfile: * modules/fnmatch, modules/group-member, modules/malloca: * modules/posixtm, modules/reallocarray: * modules/relocatable-prog-wrapper, modules/xalloc: Depend on stdckdint instead of intprops. stdckdint: new module This supports draft C23 . * doc/posix-headers/stdckdint.texi: * lib/stdckdint.in.h, modules/stdckdint: * modules/stdckdint-tests, tests/test-stdckdint.c: New files. * MODULES.html.sh, doc/gnulib.texi: Update for new module. * lib/intprops-internal.h: Include if C23 and its macros would help and our substitute has not already started to be included. (_GL_INT_ADD_WRAPV, _GL_INT_SUBTRACT_WRAPV) (_GL_INT_MULTIPLY_WRAPV): Use ckd_add, ckd_sub, ckd_mul if they are defined and would help. * lib/intprops-internal.h, lib/intprops.h: Improve comments. The C23 restrictions on stdckdint macros already mostly applied to intprops.h, so these are clarifications, not further restrictions. * tests/test-intprops.c: If TEST_STDCKDINT is defined, include instead of "intprops.h", and test it instead. (VERIFY) [TEST_STDCKDINT]: Ignore the arg in this case. (main) [TEST_STDCKDINT]: Skip tests irrelevant to stdckdint.h. intprops: refactor intprops.h into two * lib/intprops.h: Include new file intprops-internal.h.

(TYPE_SIGNED, EXPR_SIGNED, TYPE_WIDTH, INT_NEGATE_RANGE_OVERFLOW) (INT_NEGATE_OVERFLOW, INT_ADD_WRAPV, INT_SUBTRACT_WRAPV) (INT_MULTIPLY_WRAPV): Rename to _GL_ prefix, move to intprops-internal.h, and define here in terms of the _GL_ name. * lib/intprops-internal.h: New file, containing the above. * modules/intprops (Files): Add lib/intprops-internal.h. intprops: refactor _GL_HAS_BUILTIN_OVERFLOW_P * lib/intprops.h (_GL_HAS_BUILTIN_OVERFLOW_P) [_GL_HAS_BUILTIN_OVERFLOW_P]: Use __builtin_sub_overflow_p directly rather than indirectly via INT_SUBTRACT_OVERFLOW. This simplifies future changes, and doesn’t change the generated code. verify: port ‘assume’ to C23 non-GCC * lib/verify.h (assume): Use C23's unreachable if available and if GCC and/or MSC primitives are not available. 2022-08-09 Bruno Haible gnulib-tool.py: Finish implementing option --conditional-dependencies. * gnulib-tool.py (main) Accept options --conditional-dependencies, --no-conditional-dependencies. * pygnulib/GLModuleSystem.py (GLModuleTable.addConditional): Use str(module), not module, as key.

Tzvetelin Katchov). Clarify the relation to build-aux/gnu-web-doc-update. 2022-07-14 Bruno Haible doc: Fix typo. Reported by Eric Gallager in . * doc/posix-functions/mmap.texi: Add parenthesis. 2022-07-12 Paul Eggert parse-datetime: improve doc for TZ="<-07>7" etc. * doc/parse-datetime.texi (Specifying time zone rules): Give examples of POSIX TZ strings that specify UTC offsets (Bug#56524). 2022-07-10 Bruno Haible sigsegv: Optimize stackvma implementation for AIX 7. Reported by Neha Jain in via Eric Blake. * lib/stackvma.c: For AIX, add implementation that uses /proc/$pid/map, based on lib/vma-iter.c. (sigsegv_get_vma): Use it on AIX 7 or higher. 2022-07-10 Bruno Haible vma-iter: Add support for AIX 7. * lib/vma-iter.h (VMA_ITERATE_SUPPORTED): Define also on AIX. * lib/vma-iter.c (vma_iterate): Add code for AIX, known to work on AIX 7. * lib/get-rusage-as.c: Update comments. * lib/get-rusage-data.c: Likewise. * tests/test-get-rusage-as.c (main): Take into account the special address space organization on AIX in 32-bit mode. 2022-07-10 Bruno Haible iconv: Define a summary result.

Rationale: No commits since 2018 at https://git.minix3.org/. Reported by Paul Eggert and Jim Meyering in . * doc/gnulib-intro.texi (Supported Platforms): Mark Minix as no longer tested. 2022-07-09 Jim Meyering announce-gen: better diagnose some usage errors * build-aux/announce-gen (main): Erroneous usage would elicit a misleading diagnostic. When --gnulib-version=V was specified: - without --bootstrap_tools, or - with --bootstrap_tools, but without listing "gnulib" as a tool we would give an inappropriate diagnostic. Now, each diagnostic is tailored to the precise erroneous condition. Reported by Bruno Haible in https://lists.gnu.org/r/bug-gnulib/2022-01/msg00025.html 2022-07-09 Simon Josefsson git-version-gen: Doc fix. Reported by Reuben Thomas in . * build-aux/git-version-gen (usage): Replace incorrect text with bug report instructions. 2022-07-09 Simon Josefsson announce-gen: Improve GnuPG verification instructions. * build-aux/announce-gen: Add GPG fingerprint to output, and a pointer to GNU keyring. 2022-07-08 Simon Josefsson lib-symbol-visibility: Improve documentation. * doc/lib-symbol-visibility.texi: Include BUILDING_SHARED snippet suggested by Bruno Haible. 2022-07-04 Bruno Haible havelib: Fix 'configure --help' output. * m4/lib-link.m4 (AC_LIB_LINKFLAGS_BODY): Fix m4 quoting bug. 2022-07-03 Bruno Haible lib-symbol-visibility: Improve documentation. Reported by Vivien Kraus in . * doc/lib-symbol-visibility.texi: List the platforms. Extend the LIBFOO_DLL_EXPORTED to work also with mingw and also with --disable-shared. 2022-07-03 Bruno Haible supersede: Support the file name "/dev/null" on native Windows. * lib/supersede.c (open_supersede): On native Windows, map "/dev/null" to "NUL". 2022-06-23 Jim Meyering maint.mk: fix syntax-check for unnecessary hash.h header use * top/maint.mk (_hash_re): Correct the regexp. It had two problems: - lacked the "hash_" prefix, so would match non-uses - failed to detect uses of the hash_x?initialize functions The former led to an excess/unneeded use of hash.h in coreutils' cut.c. The latter would have led to a FP "not needed" report for copy.c. 2022-06-22 Bruno Haible fchmodat: Fix test failure on native Windows. * modules/fchmodat (Depends-on): Add 'chmod'. 2022-06-22 Bruno Haible chmod: Add tests. * tests/test-chmod.c: New file, based on tests/test-lchmod.c. * modules/chmod-tests: New file. chmod: New module. * lib/sys_stat.in.h (chmod): Declare when GNULIB_CHMOD is 1. * lib/chmod.c: New file, based on lib/lchmod.c. * m4/chmod.m4: New file, based on m4/fchmodat.m4. * m4/sys_stat_h.m4 (gl_SYS_STAT_H): Test whether chmod is declared. (gl_SYS_STAT_H_REQUIRE_DEFAULTS): Initialize GNULIB_CHMOD. (gl_SYS_STAT_H_DEFAULTS): Initialize REPLACE_CHMOD. * modules/sys_stat (Makefile.am): Substitute GNULIB_CHMOD, REPLACE_CHMOD. * modules/chmod: New file, based on modules/lchmod. * doc/posix-functions/chmod.texi: Mention the new module and the problems on IRIX and Windows. 2022-06-21 Bruno Haible lchmod: Simplify. * lib/lchmod.c: Remove unnecessary include, obsolete since 2020-02-23. 2022-06-20 Bruno Haible javacomp-script, javaexec-script: Add support for disabling Java. * m4/javacomp.m4 (gt_JAVACOMP_DISABLED): New macro. * m4/javaexec.m4 (gt_JAVAEXEC_DISABLED): New macro. 2022-06-19 Paul Eggert lchmod: port back to AIX 7.2 Problem reported by Bruno Haible in: https://lists.gnu.org/r/bug-gnulib/2022-06/msg00075.html * lib/lchmod.c: Include string.h, for strlen. (lchmod): Do not depend on HAVE_READLINK since we now depend on the readlink module. Check for AIX 7.2 bug. * m4/lchmod.m4 (gl_PREREQ_LCHMOD): Do not check for readlink since we now depend on the readlink module. * modules/lchmod (Depends-on): Depend on readlink. fchmodat: pacify gcc -Wunused-variable Problem reported by Bruno Haible in: https://lists.gnu.org/r/bug-gnulib/2022-06/msg00075.html * lib/fchmodat.c (fchmodat): Remove unused local. 2022-06-19 Bruno Haible getlogin, getlogin_r tests: Really avoid test failure. Reported by Letu Ren in . * tests/test-getlogin.h (test_getlogin_result): Parse the contents of /proc/self/loginuid as an unsigned integer. 2022-06-12 Paul Eggert fchmodat: port better to MS-Windows etc. MS-Windows problem reported by Bruno Haible in: https://lists.gnu.org/r/bug-gnulib/2022-06/msg00041.html Although I don’t use MS-Windows I see some related fstatat etc. problems and am trying to fix them with this further patch. * lib/fchmodat.c (fchmodat): * lib/lchmod.c (lchmod): * lib/lchown.c (lchown) [!HAVE_LCHOWN && HAVE_CHOWN && !CHOWN_MODIFIES_SYMLINK]: * lib/renameatu.c (renameatu) [HAVE_RENAME && RENAME_TRAILING_SLASH_SOURCE_BUG]: Use readlinkat/readlink instead of fstatat/lstat to test merely whether a string names a symlink, as this avoids problems with EOVERFLOW. Also, I hope it works around the MS-Windows issues that Bruno noted. * m4/fchmodat.m4 (gl_PREREQ_FCHMODAT): Check for readlinkat, not lchmod. * m4/lchmod.m4 (gl_FUNC_LCHMOD): Do not require AC_CANONICAL_HOST or check for lstat. (gl_PREREQ_LCHMOD): Check for readlink. * modules/lchown (Depends-on): Add readlink. Do not depend on lstat merely because !HAVE_LCHOWN. * modules/renameatu (Depends-on): Add fstatat, readlinkat. 2022-06-12 Bruno Haible doc: Update O_PATH platforms list. * doc/posix-headers/fcntl.texi: Update O_PATH platforms list. 2022-06-11 Paul Eggert fcntl: document O_PATH * doc/posix-headers/fcntl.texi: Mention O_PATH. fchmodat: port to old Linux kernel + newer headers Problem reported by Lance Fredrickson in: https://lists.gnu.org/r/bug-gnulib/2022-06/msg00038.html * lib/fchmodat.c (fchmodat): * lib/lchmod.c (lchmod): Do not rely on AT_EMPTY_PATH as to whether syscalls work on ""; instead, if a call fails with ENOENT assume that those syscalls do not work. Do not use fstatat to determine whether a file is a symlink, as this has problems with EOVERFLOW. Use readlinkat instead, and if it fails with EINVAL then the file is not a symlink. Remove #if tests on __linux__ || __ANDROID__ || __CYGWIN__ as this has been a maintenance hassle and it’s unlikely these days that a new platform would #define O_PATH without also either supporting /proc or keeping it absent. * modules/fchmodat (Depends-on): Remove fstatat. There should be no need for either fchmodat or lchmod to depend on readlinkat, since they use readlinkat only in contexts where it should work without Gnulib intervention. 2022-06-06 Bruno Haible fopen-gnu: Make this module work again (regression 2022-01-03). Reported by Nelson H. F. Beebe in . * modules/fopen-gnu (configure.ac): Invoke gl_STDIO_MODULE_INDICATOR. 2022-06-06 Bruno Haible getlogin, getlogin_r tests: Avoid test failure in specific environments. Reported by Letu Ren in . * modules/getlogin-tests (Depends-on): Add stdbool. * modules/getlogin_r-tests (Depends-on): Likewise. * tests/test-getlogin.h: Include stdbool.h. (test_getlogin_result): On Linux, skip the test if /proc/self/loginuid contains "-1". 2022-06-05 Bruno Haible doc: Add section to attract more people towards the GNU project. Inspired by a suggestion from José E. Marchesi on the gnu-prog-discuss mailing list. * doc/join-gnu.texi: New file. * doc/gnulib-readme.texi: Include it. 2022-06-05 Bruno Haible doc: Fix warnings about regex chapter structure (regression 2022-05-15). * doc/regex.texi (GNU Operators): Fix menu. 2022-06-04 Paul Eggert regex-quote: \} -> } in EREs * lib/regex-quote.c (ere_special): Don’t use \} in EREs, as POSIX says the interpretation is undefined. * tests/test-regex-quote.c (test_bre, test_ere): Add tests for }. dfa: do not warn about \] and \} * lib/dfa.c (lex): Do not warn about \] and \}, since they’re surely universally supported even though POSIX says their interpretation is undefined. 2022-06-03 Paul Eggert regex-quote: \] -> ] in EREs and BREs * build-aux/bootstrap: * build-aux/bootstrap.conf (gettext_external): * check-AC_LIBOBJ: * lib/regex-quote.c (bre_special, ere_special): * gnulib-tool (func_modules_transitive_closure) (func_emit_autoconf_snippet, func_import, func_create_testdir): * tests/test-regex-quote.c (test_bre, test_ere): * top/maint.mk (longopt_re, gpg_key_ID): Don’t use \] in BREs and EREs, as POSIX says the interpretation is undefined. filevercmp: don’t treat entire filename as suffix Problem reported by Artém S. Tashkinóv in: https://lists.gnu.org/r/bug-gnulib/2022-06/msg00012.html * lib/filevercmp.c (file_prefixlen): When stripping (\.[A-Za-z~][A-Za-z0-9~]*)*$ suffixes, do not strip the entire file name. * tests/test-filevercmp.c (examples): Adjust to match new behavior. 2022-06-03 Bruno Haible setlocale: Update after Turkey changed its name. * lib/setlocale.c: Update comments. 2022-05-25 Karl Berry doc: regex.texi deleted the node GNU Emacs Operators * doc/gnulib.texi (Regular expression): remove "GNU Emacs Operators" from the @menu, since the node no longer exists in regex.texi. 2022-05-24 Paul Eggert dfa: new options DFA_STAR_WARN, DFA_PLUS_WARN This lets ‘grep -E '(*a|+b)'’ warn about the * and the +. * lib/dfa.h (DFA_STAR_WARN, DFA_PLUS_WARN): New flags. * lib/dfa.c (lex): Support them. 2022-05-23 Paul Eggert dfa: '\n' is not governed by RE_LIMITED_OPS * lib/dfa.c (lex): Pay no attention to RE_LIMITED_OPS when deciding how to parse '\n', since regcomp.c doesn’t. dfa: new option DFA_STRAY_BACKSLASH_WARN This is for grep, which wants to warn about stray backslashes that lead to unspecified behavior. For example, "grep -oi '\a'" surprisingly is not equivalent to "grep -oi 'a'", so the stray backslash should be warned about. * lib/dfa.c: Include wctype.h, for iswprint and iswspace. (lex): Add support for DFA_STRAY_BACKSLASH_WARN. * lib/dfa.h (DFA_STRAY_BACKSLASH_WARN): New constant. dfa: new option DFA_CONFUSING_BRACKETS_ERROR This is for grep, which wants [:alpha:] to be an error at the top level. * lib/dfa.c (struct regex_syntax): New member dfaopts, replacing anchor. All uses changed. (parse_bracket_exp): Error, not warn, if DFA_CONFUSING_BRACKETS_ERROR. * lib/dfa.h (DFA_CONFUSING_BRACKETS_ERROR): New constant. 2022-05-21 Paul Eggert strstr-simple: pacify GCC 12.1 * lib/str-two-way.h (two_way_long_needle): Pacify GCC 12.1 -Wsuggest-attribute=pure (x86-64, -O2). 2022-05-20 Paul Eggert dfa: steer cleer of POSIX-reserved symbols * lib/dfa.c (str_eq): Rename from streq. All uses changed. (c_isdigit): Rename from isasciidigit. The function worked in EBCDIC so it wasn’t ASCII-specific anyway. All uses changed. 2022-05-17 Paul Eggert parse-datetime: support 'J' military time zone Requested by Brian Inglis in: https://savannah.gnu.org/support/?110644 * lib/parse-datetime.y (parser_control): New member J_zones_seen. (item): New item 'J'. (military_table): Add 'J'. (parse_datetime_body): Set and use J_zones_seen. * tests/test-parse-datetime.c (main): Test "J". 2022-05-15 Reuben Thomas doc: Update regex documentation to match implementation. * doc/regex.texi: remove Emacs-specific documentation; match code. Remove mention of both Emacs and non-Emacs syntax tables, as these are no longer supported by the code. Document the word character class (alnum + _). Add documentation for \s and \S. Replace mentions of #defining emacs with RE_NO_GNU_OPS (which takes effect in the opposite sense); merge the node “GNU Emacs Operators” into “GNU Operators”. For \` and \', refer to the “whole string” rather than the (Emacs) “buffer”. 2022-05-15 Bruno Haible string, wchar: Fix compilation error on MSVC (regression 2021-09-07). * lib/string.in.h (free): For MSVC, add the dllimport specification if the MSVC headers have it. * lib/wchar.in.h (free): Likewise. 2022-05-14 Bruno Haible glob tests: Fix a warning (regression from 2022-03-23). * tests/test-glob.c: Include . * modules/glob-tests (Depends-on): Add fcntl-h. 2022-05-14 Bruno Haible termcap: Fix link error when no suitable library is found. * m4/termcap.m4 (gl_TERMCAP_BODY): If no suitable library is found, set LIBTERMCAP and LTLIBTERMCAP to empty. 2022-05-13 Paul Eggert dfa: fix bug with ‘.’ and UTF-8 Hangul Syllables This fixes a bug introduced in 2019-12-18T05:41:27Z!eggert@cs.ucla.edu, an earlier patch that fixed dfa.c to not match invalid UTF-8. Unfortunately that patch had a couple of typos when dfa.c is matching against the regular expression ‘.’ (dot). One typo caused dfa.c to incorrectly reject the valid UTF-8 sequences (ED)(90-9F)(80-BF) corresponding to U+D400 through U+D7FF, which are some Hangul Syllables and Hangul Jamo Extended-B. The other typo caused dfa.c to incorrectly reject the valid sequences (F4)(88-8F)(80-BF)(80-BF) which correspond to U+108000 through U+10FFFF (Supplemental Private Use Area plane B). * lib/dfa.c (utf8_classes): Fix typos. * tests/test-dfa-match.sh: Test the fix. 2022-05-12 Paul Eggert manywarnings: update C warnings for GCC 12 Adjust for C programs compiled by GCC 12. (A C++ expert still needs to look at manywarnings-c++.m4.) * build-aux/gcc-warning.spec: Add warnings introduced in GCC 12. * m4/manywarnings.m4 (gl_MANYWARN_ALL_GCC): Add -Wbidi-chars=any,ucn and -Wuse-after-free=3. Although not enabled by -Wall or -Wextra they seem suitable for Gnulib-using C code. 2022-05-11 Paul Eggert parse-datetime: remove Emacs cruft * lib/parse-datetime.y: Remove an ‘ifdef emacs’. Emacs has never used this module. The module is derived from code taken from Emacs, but that code was removed from Emacs in the 1990s. 2022-05-11 Bruno Haible alloca: Remove old code for Emacs, unused since 2009. Reported by Reuben Thomas in . * lib/alloca.c: Remove Emacs specific code. 2022-05-05 Paul Eggert libc-config: update to match cdefs * lib/libc-config.h (__attribute_alloc_align__) (__attribute_maybe_unused, __fortified_attr_access) (__glibc_fortify, __glibc_fortify_n, __glibc_likely) (__glibc_safe_len_cond, __glibc_safe_or_unknown_len) (__glibc_unsafe_len, __glibc_unsigned_or_positive, __wur): Undef these too, since lib/cdefs.h now defines them unconditionally. cdefs: merge from glibc * lib/cdefs.h (__glibc_safe_or_unknown_len): Use glibc’s newer version. 2022-05-02 Paul Eggert gettime-res: help the compiler * lib/gettime-res.c (gettime_res): Pacify GCC versions that incorrectly complain about earlier.tv_sec not being initialized. Let GCC know that gcd args are always positive. af_alg: port to Ubuntu 22.04 Without this patch, maintainer builds of coreutils fail on Ubuntu 22.04 with diagnostics like "./lib/gl_openssl.h:79:1: error: 'MD5_Init' is deprecated: Since OpenSSL 3.0 [-Werror=deprecated-declarations]". From it appears that Gnulib needs to either define OPENSSL_API_COMPAT to a version less than 3.0, or use a compatibility layer, or assume OpenSSL 1.1.0 or later. The simplest workaround is to define OPENSSL_API_COMPAT for 1.1.1, the oldest OpenSSL release still supported. A better fix would be to rewrite the code to assume OpenSSL 1.1.1 or later, and stop using the older API. * lib/md5.h, lib/sha1.h, lib/sha256.h, lib/sha512.h, lib/sm3.h: Define OPENSSL_API_COMPAT to 0x10101000L to suppress the deprecation warnings on Ubuntu 22.04. 2022-05-01 Paul Eggert vasnprintf: Simplify. Reduce binary code size. * lib/vasnprintf.c (VASNPRINTF): Coalesce cleanup code. vasnprintf: Simplify 'result' variable. * lib/vasnprintf.c (VASNPRINTF): Simplify initialization and test of 'result' variable. vasnprintf: Simplify a free() call. * lib/vasnprintf.c (divide): Just call free (x) instead of doing ‘if (x != NULL) free (x);’. 2022-04-30 Bruno Haible string: Avoid syntax error on glibc systems with GCC 11. Reported by Tom Tromey in and by Satadru Pramanik in . * lib/string.in.h (strndup): Don't rededeclare strndup if it is defined as a macro. 2022-04-28 Simon Marchi (tiny change) stdlib: Fix error in C++ mode on glibc systems (regr. 2022-04-13). * lib/stdlib.in.h (free): Add exception specification like glibc does. 2022-04-28 Paul Eggert glob: improve config and test cleanup Config problem reported by Benno Schulenberg in: https://lists.gnu.org/r/bug-gnulib/2022-04/msg00071.html * m4/glob.m4 (gl_GLOB): Clean up temporary file. Also, name it conf$$-file not conf-file, so it’s cleaned up on interrupt. * modules/glob-tests (MOSTLYCLEANFILES): Append test-glob.tglobfile, test-glob.tgloblink[123]. 2022-04-26 Paul Eggert glob: port to NetBSD 9.2 Problem reported by Benno Schulenberg in: https://lists.gnu.org/r/bug-gnulib/2022-04/msg00052.html * doc/posix-functions/dirfd.texi: Document NetBSD 9.2 portability bugs. Remove an old comment about errno that is no longer true of POSIX 2018. * lib/glob.c (glob_in_dir): Convert dirfd arg from void * to DIR * before passing it to dirfd. 2022-04-21 Paul Eggert regex: match [...---...] like V7 grep Problem reported by Arnold Robbins in: https://bugs.gnu.org/20657 https://lists.gnu.org/r/bug-gnulib/2022-04/msg00053.html * lib/regcomp.c (peek_token_bracket): Let [...---...] match '-'. This is an extension to POSIX, and matches V7 Unix grep. 2022-04-20 Paul Eggert backupfile: fix bug when renaming simple backups * lib/backupfile.c (backupfile_internal): Fix bug when RENAME and when doing simple backups. Problem reported by Steve Ward in: https://bugs.gnu.org/55029 gettime-res: more-robust sampling * lib/gettime-res.c (gettime_res): If adjacent timestamps are identical search for a differing timestamp. Also, stop collecting samples thereafter since they surely won’t help. 2022-04-19 Paul Eggert Port _GL_HAS_C_ATTRIBUTE to pedantic gcc -std=c99 * m4/gnulib-common.m4 (_GL_HAS_C_ATTRIBUTE): Disable -Wpedantic if using __has_c_attribute and this is not C2x. verify: port to pedantic gcc -std=c99 * lib/verify.h (_GL_VERIFY): If we lack both _Static_assert and static_assert, suppress -Wnexted-externs. gettime-res: add tests * modules/gettime-res-tests, tests/test-gettime-res.c: New files. 2022-04-16 Paul Eggert verify: port to Mac OS 10.7.5 Mac OS 10.7.5 clang sets __clang_major__ to 4 even though it was derived from Clang 3.2. Problem reported by Werner Lemberg in: https://lists.gnu.org/r/emacs-devel/2022-04/msg00779.html * lib/verify.h (_GL_HAVE__STATIC_ASSERT): Don’t define to 1 when __clang_major__ == 4 && !__cplusplus && __STDC_VERSION__ < 201112L && !defined __STRICT_ANSI__. 2022-04-15 Bruno Haible sigsegv: Fix compilation error on arceb CPUs. Reported by Fabrice Fontaine in . * m4/stack-direction.m4 (SV_STACK_DIRECTION): Treat the 'arc' variants like 'arc'. 2022-04-13 Bruno Haible string, wchar: Fix error in C++ mode on glibc systems with clang. * lib/string.in.h (free): Add exception specification like glibc does. * lib/wchar.in.h (free): Likewise. 2022-04-13 Bruno Haible string: Fix errors in C++ mode on glibc systems with clang. * lib/string.in.h (memchr, memrchr, rawmemchr, strchrnul, strpbrk, strstr, strcasestr): Use _GL_CXXALIASWARN1 also with clang, and add exception specification. 2022-04-13 Bruno Haible math: Fix errors in C++ mode on glibc systems with clang. * lib/math.in.h (GNULIB_NAMESPACE_LACKS_ISFINITE, GNULIB_NAMESPACE_LACKS_ISINF, GNULIB_NAMESPACE_LACKS_ISNAN, GNULIB_NAMESPACE_LACKS_SIGNBIT): New macros. * tests/test-math-c++.cc (isfinite): Skip test if GNULIB_NAMESPACE_LACKS_ISFINITE is 1. (isinf): Skip test if GNULIB_NAMESPACE_LACKS_ISINF is 1. (isnan): Skip test if GNULIB_NAMESPACE_LACKS_ISNAN is 1. (signbit): Skip test if GNULIB_NAMESPACE_LACKS_SIGNBIT is 1. 2022-04-08 Paul Eggert libgmp: pacify Clang too * lib/mini-gmp-gnulib.c [NDEBUG]: Also use -Wunused-variable if clang. Problem reported for Emacs by Mattias Engdegård. 2022-04-04 Paul Eggert init.sh: don’t assume gzip * tests/init.sh (rand_bytes_): Don’t assume gzip is installed. I found this while testing gzip installation on a platform where I had removed the installed gzip. gzip is executed only on platforms lacking mktemp and /dev/urandom so this code is rarely used; however, these platforms might also lack gzip since gzip is neither specified by POSIX or required by the GNU Coding Standards. 2022-03-30 Paul Eggert glob: sync better with glibc * lib/glob.c (dirfd) [_LIBC]: Use #undef instead of #ifdef. Problem reported by DJ Delorie. 2022-03-23 Paul Eggert glob: test for glibc bug 25659 https://sourceware.org/bugzilla/show_bug.cgi?id=25659 * m4/glob.m4 (gl_GLOB): Replace glob if it has bug 25659. * tests/test-glob.c (main): Test for glibc bug 25659. glob: fix symlink and // issues; improve speed * lib/glob.c: Include fcntl.h. (dirfd) [_LIBC]: New macro. (GLOB_STAT64, GLOB_LSTAT64): Remove. Replace all uses with ... (GLOB_FSTATAT64): ... this new macro. (glob_in_dir): Treat DT_LNK like DT_UNKNOWN. Use directory-relative fstatat unless GLOB_ALTDIRFUNC, or dirfd fails. Avoid duplicate strlen (directory). Work even if directory is "/", without turning it into "//". Use a scratch buffer instead of by-hand alloca stuff. Use mempcpy and memcpy instead of stpcpy and strcpy. * modules/glob (Depends-on): Add dirfd, fstatat. Remove stat. (License): Change from LGPLv2+ to GPL, since it depends on fstatat. 2022-03-23 DJ Delorie glob: resolve DT_UNKNOWN via is_dir The DT_* values returned by getdents (readdir) are only hints and not required. In fact, some Linux filesystems return DT_UNKNOWN for most entries, regardless of actual type. This causes make to mis-match patterns with a trailing slash (via GLOB_ONLYDIR) (see make's functions/wildcard test case). Thus, this patch detects that case and uses is_dir() to make the type known enough for proper operation. Performance in non-DT_UNKNOWN cases is not affected. The lack of DT_* is a well known issue on older XFS installations (for example, RHEL 7 and 8, Fedora 28) but can be recreated by creating an XFS filesystem with flags that mimic older behavior: $ fallocate -l 10G /xfs.fs $ mkfs.xfs -n ftype=0 -m crc=0 -f /xfs.fs $ mkdir /xfs $ mount -o loop /xfs.fs /xfs 2022-03-20 Jim Meyering maint: bootstrap: split a too-long line * build-aux/bootstrap (git_modules_config): Split longer-than-80 line. 2022-03-14 Simon Josefsson announce-gen: Modernize GnuPG key retrieval suggestions. Based on patch by Darshit Shah in: https://lists.gnu.org/archive/html/bug-gnulib/2022-03/msg00022.html * build-aux/announce-gen (usage): Add --gpg-key-email and --gpg-keyring-url. (main): Support the new options. (main): Don't suggest 'gpg --keyserver' since the situation with public key servers is complicated and GnuPG version dependent. maintainer-makefile: Improve GnuPG announce-gen options. * top/maint.mk (gpg_key_emil): New variable. (gpg_keyring_url): New variable. (announcement): Pass them as --gpg-key-email and --gpg-keyring-url. 2022-03-13 Ben Pfaff Document Automake 1.14 requirement in NEWS, too, since it had been documented there before for the Automake 1.11 requirement. * NEWS: Mention the change. 2022-03-13 Bruno Haible sigsegv: Add support for Linux/PowerPC (32-bit) with musl libc. Reported by Khem Raj in . * src/sigsegv.c (SIGSEGV_FAULT_STACKPOINTER): In the Linux/PowerPC 32-bit case, handle musl libc differently. * modules/sigsegv (Files): Add m4/musl.m4. (configure.ac): Invoke gl_MUSL_LIBC. 2022-03-11 Paul Eggert regex: fix double-free * lib/regex_internal.c (re_dfa_add_node): Don’t free storage twice if an allocation fails. regex: fix minor over-allocation * lib/regexec.c (push_fail_stack): Fix off-by-one error that over-allocated the stack. regex: fix free_fail_stack undefined behavior * lib/regexec.c (push_fail_stack): Don’t increment number of re_fail_stack_t entries until after successful allocation. This prevents a crash if re_realloc or re_malloc fails here, and a later free_fail_stack examines regs or a later pop_fail_stack examines node. Problem discovered by Coverity scan sent 2022-03-11 11:03:52Z. 2022-03-10 Paul Eggert fts: revert change to use AT_NO_AUTOMOUNT * NEWS: Don’t mention AT_NO_AUTOMOUNT. * lib/fts.c (fts_stat): Don’t use AT_NO_AUTOMOUNT, as it has no effect with fstatat. 2022-03-09 Paul Eggert statat: now obsolete * lib/openat.h (statat, lstatat): Now deprecated. All uses removed, and replaced with fstatat. * modules/statat: Mark as obsolete, because it’s confusing: it’s not clear whether it should use AT_NO_AUTOMOUNT, which is implied by stat and by lstat, but not by fstatat. * tests/test-statat.c: Disable deprecated-declarations warnings. fts: be consistent about AT_NO_AUTOMOUNT * lib/fts.c (fts_stat): Use fstatat with AT_NO_AUTOMOUNT consistently, instead of sometimes using stat (which implies AT_NO_AUTOMOUNT) and sometimes using fstatat without AT_NO_AUTOMOUNT. Remove a goto while we’re at it. 2022-03-07 Pádraig Brady fcntl-h: add AT_NO_AUTOMOUNT * lib/fcntl.in.h: Define AT_NO_AUTOMOUNT to 0 where not defined. This is available on Linux since 2.6.38. 2022-03-01 Paul Eggert Create lib/Makefile.am after gnulib-comp.m4 * gnulib-tool (func_import): Create library makefile after creating gnulib-comp.m4. With --gnu-make, the latter depends on the former. See . 2022-02-26 Paul Eggert gettime-res: fix unlikely overflow bug * lib/gettime-res.c (gettime_res): Fix bug when hz * tv_sec overflows. With 64-bit ‘long’ and nanosecond resolution the bug can occur starting in the year 2262, with probability about 2e-9. With 32-bit ‘long’ the bug can occur now, with same probability. The probability goes up on hosts with worse timestamp resolution. Document clang -fsanitize=undefined glitch * doc/gnulib-intro.texi (Unsupported Platforms): Document incompatibility of ‘clang -fsanitize=undefined’ with Gnulib, and how to work around it by also using ‘-fno-sanitize=pointer-overflow’. 2022-02-25 Darshit Shah modules/unicase/special-casing: Fix compilation error * modules/unicase/special-casing: Don't prepend $(AM_V_at) to the second part of a compound command. It causes make to try and execute the command "@sed" which doesn't exist. 2022-02-25 Paul Eggert Port __has_attribute to Apple’s Clang renumbering Problem reported by Kirill A. Korinsky in: https://lists.gnu.org/r/bug-gnulib/2022-02/msg00034.html * config/srclist.txt: Comment out sys/cdefs.h for now. * lib/cdefs.h (__glibc_has_attribute): * m4/gnulib-common.m4 (gl_COMMON_BODY): Port to Apple’s renumbering of Clang versions. nanosleep: simplify by using pselect GNU Emacs avoids Gnulib’s ‘select’ module and uses only pselect, which it implements in a special way on MS-DOS. Unfortunately, though, nanosleep uses ‘select’; problem reported by Lars Ingebrigtsen (Bug#32452#74). As far as I can tell, Gnulib nanosleep's use of ‘select’ with signals is only for ancient platforms that Gnulib no longer cares about, so remove that use of ‘select’. I don’t know of any platforms that still need this fallback code, but just in case, fall back to pselect instead, while removing signal handling that it shouldn’t be needed nowadays. * lib/nanosleep.c: Do not include sig-handler.h, sys/time.h. (SIGCONT, suspended, sighandler, my_usleep): Remove. (nanosleep) [!HAVE_BUG_BIG_NANOSLEEP && !(_WIN32 && !__CYGWIN__)]: Just call pselect. * m4/nanosleep.m4 (gl_FUNC_NANOSLEEP): Do not check for sys/time.h or call gl_FUNC_SELECT. Do not include sys/time.h or worry about LIBSOCKET. (gl_PREREQ_NANOSLEEP): Remove as it’s no longer needed. All uses removed. * modules/nanosleep (Depends-on): Add pselect. Remove select, sigaction, sys_time. 2022-02-24 Paul Eggert userspec: warn about '.' separator Problem reported by Dan Jacobson (Bug#44770). * lib/userspec.c: Don’t include stdbool.h since it’s now in our API. (parse_user_spec_warn): New function, broken out of parse_user_spec and with a new PWARN arg. (parse_user_spec): Use it. * lib/userspec.h: Include stdbool.h and declare new function. * tests/test-userspec.c (struct test.in): Now a char array so that it can be modified. (T): Make the placeholder a valid test, as that simplifies the code. Omit NULL placeholder at the end, likewise. (main): Set up T in the new way, and test that the "." separator acts like the ":" separator except with a warning if it works. userspec: no need for static vars * lib/userspec.c (parse_with_separator): Simplify. 2022-02-22 Benno Schulenberg (tiny change) doc: add two missing closing parentheses * doc/regex.texi (Syntax Bits): Add missing closing parenthesis. * doc/regex.texi (BSD Regular Expression Compiling): Likewise. 2022-02-22 Simon Josefsson gnulib-tool: Bump automake dependency. * gnulib-tool (func_emit_lib_Makefile_am) (func_emit_tests_Makefile_am): Demand Automake ≥ 1.14, for %reldir%. 2022-02-21 Paul Eggert close-stream: don't depend on fclose This reverts 2022-01-26T17:33:03Z!eggert@cs.ucla.edu. Depending on fclose broke Emacs, and since this dependency didn't help GNU m4 let's remove it for now. Problem reported by Lars Ingebrigtsen . * modules/close-stream (Depends-on): Remove fclose. 2022-02-20 Bruno Haible Document that Automake ≥ 1.14 is needed (regression 2021-12-15). Reported by Simon Josefsson and Mike Frysinger in . * DEPENDENCIES (Automake): Require version 1.14 or newer. 2022-02-19 Paul Eggert mktime: improve heuristic for ca-1986 Indiana DST Problem reported by Mark Krenz . * lib/mktime.c (__mktime_internal): Be more generous about accepting arguments with the wrong value of tm_isdst, by falling back to a one-hour DST difference if we find no nearby DST that is unusual. This fixes a problem where "1986-04-28 00:00 EDT" was rejected when TZ="America/Indianapolis" because the nearest DST timestamp occurred in 1970, a temporal distance too great for the old heuristic. This also also narrows the search a bit, which is a minor performance win. * m4/mktime.m4 (gl_FUNC_MKTIME_WORKS): Check for putenv failures and for Bug#48085. * tests/test-parse-datetime.c (main): Test for setenv failures and for Bug#48085. 2022-02-12 Paul Eggert filevercmp: fix several unexpected results Problems reported by Michael Debertol in . While looking into this, I spotted some more areas where the code and documentation did not agree, or where the documentation was unclear. The biggest change needed by coreutils is a new function filenvercmp that can compare byte strings containing NUL. * lib/filevercmp.c: Do not include sys/types.h, stdlib.h, string.h. Include idx.h, verify.h. (match_suffix): Remove, replacing all uses with calls to ... (file_prefixlen): ... this new function. Simplify it by avoiding the need for a confusing READ_ALPHA state variable. Change its API to something more useful, with a *LEN arg. it with a new *LEN arg. (file_prefixlen, verrevcmp): Prefer idx_t to size_t where either will do. (order): Change args to S, POS, LEN instead of just S[POS]. This lets us handle NUL bytes correctly. Callers changed. Verify that ints are sufficiently wide for its API. (verrevcmp): Don't assume that S1[S1_LEN] is a non-digit, and likewise for S2[S2_LEN]. The byte might not be accessible if filenvercmp is being called. (filevercmp): Reimplement by calling filenvercmp. (filenvercmp): New function, rewritten without the assumption that the inputs are null-terminated. Remove "easy comparison to see if strings are identical", as the use of it later (a) was undocumented, and (b) caused sort -V to be unstable. When both strings start with ".", do not skip past the "."s before looking for suffixes, as this disagreed with the documentation. * lib/filevercmp.h: Fix comments, which had many mistakes. (filenvercmp): New decl. * modules/filevercmp (Depends-on): Add idx, verify. Remove string. * tests/test-filevercmp.c: Include string.h. (examples): Reorder examples ".0" and ".9" that matched the code but not the documentation. The code has been fixed to match the documentation. Add some examples involving \1 so that they can be tried with both \1 and \0. Add some other examples taken from the bug report. (equals): New set of test cases. (sign, test_filevercmp): New functions. (main): Remove test case where the fixed filevercmp disagrees with strverscmp. Use test_filevercmp instead of filevercmp, so that we also test filenvercmp. Test the newly-introduced EQUALS cases. 2022-02-09 Bruno Haible string: Fix "mismatched allocation function" warnings regarding strndup. * lib/string.in.h (strndup): Mark with _GL_ATTRIBUTE_MALLOC and _GL_ATTRIBUTE_DEALLOC_FREE. For GCC >= 11: Declare also when the platform already declares the function or when the module 'strndup' is not in use. 2022-02-09 Bruno Haible unictype/category-byname: Fix test failure. * modules/unictype/category-byname (configure.ac): Bump required libunistring version. 2022-02-06 Bruno Haible termcap, termcap-h: Deprecate. * modules/termcap (Status, Notice): Add deprecation. * modules/termcap-h (Status, Notice): Likewise. 2022-02-05 Paul Eggert parse-datetime: allow calculations to yield -1 Problem reported by Jeremy Cantrell . * lib/parse-datetime.y (parse_datetime_body): When calling mktime, use an unmodifed and negative tm_wday or tm_yday to detect an error, as a (time_t) -1 return value is valid on most hosts. * tests/test-parse-datetime.c (main): Add a test for the bug. 2022-02-04 Paul Eggert userspec: help fix GNU ‘id’ incompatibility * lib/userspec.c (parse_with_separator): Don’t set *username to a numeric string that is not a user name, and similarly for *groupname. Needed to fix Bug#53631. 2022-01-30 Pádraig Brady argmatch: add variants that only match full argument * lib/argmatch.h (argmatch_exact, [X]ARGMATCH_EXACT): New interfaces that don't allow abbreviations. * lib/argmatch.c (argmatch_exact): Likewise. (__xargmatch_internal): Add a bool parameter to disable abbreviations. * tests/test-argmatch.c: Add tests. 2022-01-30 Bruno Haible tests: Fix interpretation of setupterm's return code. * tests/test-terminfo.c (main): Test the value of err when setupterm fails, not when it succeeds. * tests/test-termcap.c (main): Likewise. 2022-01-30 Bruno Haible terminfo: Add tests. * tests/test-terminfo.c: New file. * modules/terminfo-tests: New file. terminfo, terminfo-h: New modules. * lib/terminfo.h: New file, from GNU gettext. * m4/terminfo.m4: New file, from GNU gettext. * modules/terminfo: New file, from GNU gettext. * modules/terminfo-h: New file, from GNU gettext. 2022-01-30 Bruno Haible termcap: Add tests. * tests/test-termcap.c: New file. * modules/termcap-tests: New file. termcap, termcap-h: New modules. * lib/termcap.h: New file, from GNU gettext. * lib/tparm.c: New file, from GNU gettext. * lib/tputs.c: New file, from GNU gettext. * m4/termcap.m4: New file, from GNU gettext. * m4/curses.m4: New file, from GNU gettext. * modules/termcap: New file, from GNU gettext. * modules/termcap-h: New file, from GNU gettext. 2022-01-29 Bruno Haible doc: Clarify MSVC support. * doc/gnulib-intro.texi (Supported Platforms): Document that "debug" builds are unsupported. 2022-01-28 Pádraig Brady maintainer-makefile: fix sc_error_message_uppercase false failure * top/maint.mk (sc_error_message_uppercase): Don't trigger for any of the PRI... defines. 2022-01-27 Paul Eggert alignalloc: work around AddressSanitizer bug * doc/posix-functions/aligned_alloc.texi (aligned_alloc): Mention AddressSanitizer bug. * lib/alignalloc.h (ALIGNALLOC_VIA_ALIGNED_ALLOC): Define to 0 if AddressSanitizer is in use. * tests/test-alignalloc.c (test_alignalloc): New function, which tests for non-aligned sizes too. (main): Use it. Don’t bother checking for alignments greater than 16 MiB, as this flummoxes AddressSanitizer and there seems little point to testing them. doc: use UTF-8 encoding * doc/gnulib.texi: Use ‘@documentencoding UTF-8’. Partly this is because there are a few UTF-8 characters in the .texi files and there seems little point nowadays to @U-ifiying them. And partly it is so that the .info output uses nicer UTF-8 characters, e.g., it single-quotes ‘like this’ instead of 'like this'. maint: Update copyright notices * build-aux/announce-gen, build-aux/declared.sh: * build-aux/git-version-gen, build-aux/gitlog-to-changelog: * build-aux/gnu-web-doc-update, build-aux/gnupload: * build-aux/increment-serial, build-aux/libtool-next-version: * build-aux/useless-if-before-free: Update some copyright notices by hand, that were not updated automatically. 2022-01-26 Paul Eggert calloc-gnu: fix misspelling in 2022-01-03 patch Problem reported by Thien-Thi Nguyen in: https://lists.gnu.org/r/bug-gnulib/2022-01/msg00170.html * modules/calloc-gnu (Depends-on): * modules/calloc-posix (Depends-on): Fix misspelling of REPLACE_CALLOC_FOR_CALLOC_POSIX. close-stream: avoid crash on MSVC Debug mode Problem reported by Julien Marrec in: https://lists.gnu.org/r/bug-m4/2022-01/msg00000.html * modules/close-stream (Depends-on): Depend on fclose. 2022-01-23 Paul Eggert xstrtoimax, xstrtoumax: depend on inttypes-incomplete This fixes a call to strtoimax without declaring it, and similarly for strtoumax. * lib/xstrtoimax.c, lib/xstrtoumax.c (XSTRTOL_INCLUDE_INTTYPES_H): Define, so that strtoimax and strtoumax are declared. * lib/xstrtol.c [XSTRTOL_INCLUDE_INTTYPES_H]: Include inttypes.h. * modules/xstrtoimax, modules/xstrtoumax (Depends-on): Add inttypes-incomplete. alignalloc, xalignalloc: new modules * lib/alignalloc.c, lib/alignalloc.h, lib/xalignalloc.c: * m4/alignalloc.m4, modules/alignalloc, modules/alignalloc-tests: * modules/xalignalloc, tests/test-alignalloc.c: New files. 2022-01-17 Paul Eggert extern-inline: improve macOS port * m4/extern-inline.m4 (gl_EXTERN_INLINE): Define HAVE___HEADER_INLINE at configure-time, so that config.h knows the workaround is not needed even though ctype.h has not yet been included. This lets the compiler use extern inline functions on newer macOS platforms, instead of static inline. Problem reported by Reuben Thomas in: https://lists.gnu.org/r/bug-gnulib/2022-01/msg00130.html 2022-01-17 Bruno Haible xstrtol: Trim dependencies. * lib/xstrtol.h: Include , not . * modules/xstrtol (Depends-on): Add stdint.

(TYPE_SIGNED): Remove, as intprops.h defines that for us now. (bkm_scale): Use INT_MULTIPLY_WRAPV instead of checking for overflow by hand. xstrtoll-tests: use %lld for long long * tests/test-xstrtoll.c, tests/test-xstrtoull.c (__spec): Do not assume long long is 64 bits, or that exact-width 64-bit types exist. Although these assumptions are true on current Gnulib platforms they are not true in general. Also, GCC warns if PRId64 is "ld" but intmax_t is long long even when long and long long are both 64 bits. 2022-01-15 Bruno Haible Don't pass unknown warning option to clang. Reported by Assaf Gordon via Paul Eggert in . * m4/gnulib-common.m4 (gl_CC_GNULIB_WARNINGS): Don't use -Wno-unsuffixed-float-constants with clang. 2022-01-15 Bruno Haible log tests: Avoid test failure with nvc 22.1. * tests/test-log.h (test_function): With nvc, expect up to 4 ulps error. 2022-01-15 Bruno Haible havelib: Recognize ELF platform despite nvc 22.1. * m4/lib-prefix.m4 (AC_LIB_PREPARE_MULTILIB): Recognize Linux as an ELF platform, even with a compiler that does not define __ELF__. 2022-01-15 Bruno Haible oset-c++: Avoid compilation error with nvc++ 22.1. * lib/gl_oset.hh: With EDG C++ compilers, avoid 'friend'. 2022-01-14 Paul Eggert nstrftime: pacify nvc 22.1 unreachable statement * lib/nstrftime.c (__strftime_internal): Omit unreachable ‘break;’. tests: pacify nvc 22.1 unreachable statement * tests/test-sys_wait.h (test_sys_wait_macros): Widen scope of ‘#if 0’ so that there is not an unreachable ‘break;’. tests: pacify nvc 22.1 set-but-not-used * tests/test-fnmatch.c (main): Don’t set a var without using it. * tests/test-sched.c (f1): Now extern. intprops: work around nvc 22.1 bug Problem reported by Olivier Cessenat (Bug#53256). * lib/intprops.h (_GL_HAS_BUILTIN_ADD_OVERFLOW) [__EDG__]: Define to 0, since __builtin_add_overflow doesn’t work on NVIDIA HPC SDK 22.1. copy-file-range: work around Linux kernel bug This workaround is adapted from Coreutils. * lib/copy-file-range.c [__linux__ && HAVE_COPY_FILE_RANGE]: Include . (copy_file_range): Use a stub to replace the copy_file_range of Linux kernel versions 4.5 through 5.2. * lib/unistd.in.h (copy_file_range): * m4/unistd_h.m4 (gl_UNISTD_H_DEFAULTS): * modules/copy-file-range (configure.ac): * modules/unistd (unistd.h): Support replacement of copy_file_range. * m4/copy-file-range.m4 (gl_FUNC_COPY_FILE_RANGE): Define HAVE_COPY_FILE_RANGE if the system has copy_file_range, and on Linux check whether the system’s is known to work. 2022-01-14 Bruno Haible Avoid error "conditional LIBUNISTRING_COMPILE_... was never defined" when option --conditional-dependencies is used (regression 2022-01-09). Reported by Gavin Smith in . * m4/libunistring-base.m4 (gl_LIBUNISTRING_MODULE): Use gl_CONDITIONAL instead of AM_CONDITIONAL. 2022-01-13 Bruno Haible Avoid warning "_GL_ATTRIBUTE_DEALLOC_FREE redefined" (regr. 2022-01-04). Reported by Werner Lemberg in . * m4/gnulib-common.m4 (gl_COMMON_BODY): Avoid redefining _GL_ATTRIBUTE_DEALLOC_FREE. 2022-01-10 Paul Eggert backupfile: fix bug when renaming not from wd * lib/backupfile.c (backupfile_internal): Fix bug when DIR_FD does not specify the working directory, and when RENAME. Without the bug fix, FILE is treated as relative to the working directory, not relative to DIR_FD, when renaming FILE. This bug was introduced when DIR_FD and RENAME were introduced, in 2018-10-24T02:10:21Z!eggert@cs.ucla.edu. While we’re at it, when SDIR is nonnegative improve performance a bit by passing an SDIR-relative old name to renameatu. 2022-01-09 Bruno Haible host-cpu-c-abi: Add support for LoongArch64 CPU. * m4/host-cpu-c-abi.m4 (gl_HOST_CPU_C_ABI): Define __loongarch64__.

And it’s also good practice even if the default Automake ‘AM_V_GEN=@echo GEN $@;’ is used, as it’s better to output the GEN line consistently at the start of every recipe, even if this precedes a preparatory command that almost always works silently. * modules/arpa_inet, modules/dynarray, modules/net_if: * modules/netinet_in, modules/scratch_buffer, modules/selinux-h: * modules/sys_file, modules/sys_ioctl, modules/sys_random: * modules/sys_resource, modules/sys_select, modules/sys_socket: * modules/sys_stat, modules/sys_time, modules/sys_times: * modules/sys_types, modules/sys_uio, modules/sys_utsname: * modules/sys_wait, modules/unicase/special-casing, top/maint.mk: Use AM_V_GEN only at the start of each recipe. 2021-12-21 Bruno Haible c-xvasprintf: Fix declarations (regression 2021-08-07). * lib/c-xvasprintf.h (c_xasprintf, c_xvasprintf): Remove _GL_ATTRIBUTE_RETURNS_NONNULL attribute. 2021-12-21 Bruno Haible snippet/warn-on-use: Fix compilation error in C++ mode on OpenBSD 7.0. * lib/warn-on-use.h (_GL_WARN_ON_USE): In C++ mode, declare function with "C" linkage. 2021-12-21 Bruno Haible Optimize redundant 'mkdir -p .' invocations.

(renameatu): Use the new function, to avoid a bug when renameatx_np fails with errno == ENOTSUP. Don’t try to support RENAME_EXCHANGE; the old code didn’t work and nobody using using RENAME_EXCHANGE anyway. 2021-12-12 Bruno Haible gnulib-tool: Try to support non-recursive-gnulib-prefix-hack with tests. * gnulib-tool (func_import): Synthesize an AC_CONFIG_LIBOBJ_DIR invocation. * m4/non-recursive-gnulib-prefix-hack.m4 (gl_NON_RECURSIVE_GNULIB_PREFIX_HACK): Don't invoke AC_CONFIG_LIBOBJ_DIR. 2021-12-12 Paul Eggert bootstrap: refactor for GNU tar * build-aux/bootstrap (gitignore_entries, insert_if_absent) (insert_vc_ignore, symlink_to_dir): Define these shell functions before including bootstrap.conf. This is for GNU tar, whose bootstrap.conf uses symlink_to_dir. 2021-12-12 Bruno Haible gnulib-tool: Support different basenames for the lib/,tests/ Makefiles. * gnulib-tool: New option --tests-makefile-name. (tests_makefile_name): New variable. (func_import): Add support for --tests-makefile-name. Replace local variable makefile_am with two local variables source_makefile_am, tests_makefile_am. * m4/gnulib-tool.m4 (gl_TESTS_MAKEFILE_NAME): New macro. 2021-12-11 Bruno Haible get_ppid_of, get_progname_of: Fix compilation error on Mac OS X < 10.5.

Prefer idx_t to size_t where either will do. Use imalloc and irealloc instead of malloc and realloc. * modules/backupfile, modules/backup-rename (Depends-on): Depend on ialloc not idx. backupfile: fix numbered backups for XXX/ * lib/backupfile.c (check_extension): Return a bool indicating whether the original extension was OK. Caller changed. (numbered_backup): Require that FILELEN does not count trailing slashes after a non-slash, and don’t require that *BUF be null-terminated. Caller changed. This fixes a bug where the numbered backup file name for X/ was incorrectly computed because the slash messed up the code looking for X.~1~, X.~2~, etc., and this caused numbered_backup to loop forever. Also, check that check_extension doesn’t truncate a file name leading to an infloop. 2021-12-07 Paul Eggert regex: pacify Coverity clean_state_log_if_needed Problem reported by Robbie Harwood in: https://lists.gnu.org/r/bug-gnulib/2021-12/msg00005.html * lib/regexec.c (clean_state_log_if_needed): Add a DEBUG_ASSERT; this both pacifies Coverity and will help to debug in case some other change mistakenly causes the assertion to become false. 2021-12-07 Bruno Haible gettext-h: Optimize also for clang. * lib/gettext.h (pgettext_aux, npgettext_aux, dcpgettext_expr, dcnpgettext_expr): Inline also on clang. 2021-12-06 Bruno Haible intprops: Break sync with glibc. * config/srclist.txt: Comment out intprops.h. 2021-12-06 Paul Eggert intprops: streamline and get ready for Clang 14 * lib/intprops.h (_GL_HAS_BUILTIN_ADD_OVERFLOW): Rely on __has_builtin first, since GCC didn’t introduce it until GCC 9 so we don’t need to special-case GCC first. (_GL_HAS_BUILTIN_ADD_OVERFLOW, _GL_HAS_BUILTIN_OVERFLOW_P): Look at __EDG__ rather than __ICC, since icc defines __EDG__ too. (_GL_HAS_BUILTIN_MUL_OVERFLOW): Define to 1 in Clang 14 and later, as a bug fix is scheduled for Clang 14. (_GL_HAS_BUILTIN_OVERFLOW_P): Do not bother to special-case __clang__, since __has_builtin should do the right thing anyway. 2021-12-06 Bruno Haible intprops: Treat EDG-based compilers like Intel compilers. Reported by Ilya Kurdyukov in . * lib/intprops.h (_GL_HAS_BUILTIN_OVERFLOW_P): Define to 0 on EDG-based compilers. 2021-12-05 Bruno Haible sigsegv: Fix build on some more embedded CPUs. * m4/stack-direction.m4 (SV_STACK_DIRECTION): Assume the stack grows negative, when the GCC 11 sources say so. 2021-11-30 Paul Eggert sys_random: port better to uClibc < 1.0.35 Problem reported by Fabrice Fontaine in: https://lists.gnu.org/r/bug-gnulib/2021-11/msg00043.html * lib/sys_random.in.h [HAVE_SYS_RANDOM_H && !__GLIBC__ && __UCLIBC__]: Include , in case this file is included before __UCLIBC__ is defined. 2021-11-27 Paul Eggert gettext-h: document GNULIB_NO_VLA * doc/gnulib-readme.texi (C99 features avoided): Document GNULIB_NO_VLA. gettext-h: use VLA test similar to regex * lib/gettext.h (_LIBGETTEXT_HAVE_VARIABLE_SIZE_ARRAYS): Assuming GNULIB_NO_VLA, define if (defined __STDC_VERSION__ && 199901L <= __STDC_VERSION__ \ + && !defined __STDC_NO_VLA___), not if ((__GNUC__ >= 3 || __GNUG__ >= 2) && !defined __STRICT_ANSI__). This is more consistent with what the regex module does. * modules/gettext-h (Depends-on): Depend on vararrays, since lib/gettext.h uses __STDC_NO_VLA__. regex: port to tcc Problem reported by Benno Schulenberg in: https://lists.gnu.org/r/bug-gnulib/2021-11/msg00038.html * modules/regex (Depends-on): Depend on vararrays, since lib/regex.h uses __STDC_NO_VLA__. * modules/vararrays: Change license from LGPL to LGPLv2+. 2021-11-25 Bernhard Voelker test-framework-sh: remove unsafe entries from PATH Running tests with '.' in the PATH may yield unspecified results, and is deemed unsafe per se. This includes empty entries as well which are treated like a '.' entry as per POSIX. * tests/init.sh (setup_): Add snippet to remove relative and non- accessible entries from the PATH environment variable. 2021-11-24 Paul Eggert regex: merge from glibc The main change here, imported from Glibc, is for the regex code to stop using nested functions when _LIBC is defined. The intent is for the result to be copied back to Glibc so that the two implementations can resync. * lib/regcomp.c (re_set_fastmap, seek_collating_symbol_entry) (lookup_collation_sequence_value, build_range_exp) (build_collating_symbol): * lib/regexec.c (acquire_init_state_context): Declare with __always_inline instead of with ‘inline __attribute__ ((always_inline))’. * lib/regexec.c (init_word_char): Move uint64_t comment to regex_internal.h. (parse_byte): Change multibyte-detecting arg from re_charset_t * to re_dfa_t const *. All callers changed. (build_range_exp, build_collating_symbol) [!_LIBC]: Change signature to match _LIBC well enough so that the caller can be simplified to assume _LIBC. (parse_bracket_exp): Pull its nested functions seek_collating_symbol_entry, lookup_collation_sequence_value, build_range_exp, build_collating_symbol out to the top level, adding args to pass the information instead of having them access nonlocal vars. Use types in local vars that do not assume glibc. * lib/regex_internal.h: Explain uint64_t etc. here. 2021-11-23 Paul Eggert regex: assume RE_ENABLE_I18N These days there is no longer any need to port to platforms lacking iswctype etc., since Gnulib now has substitutes. * config/srclist.txt: Comment out regex_internal.c and regex_internal.h for now, since they no longer match glibc. The intent is to merge them again soon. * lib/regex_internal.h (RE_ENABLE_I18N): Remove. All uses changed to assume that RE_ENABLE_I18N is 1. * modules/regex (Depends-on): Add iswctype. 2021-11-15 Paul Eggert lseek: port around macOS SEEK_HOLE glitch Problem reported by Sudhip Nashi (Bug#51857#47). * lib/lseek.c (rpl_lseek): Work around macOS lseek+SEEK_HOLE returning -1 with ENXIO if there are no holes before EOF, contrary to the macOS documentation. lseek: port around macOS SEEK_DATA glitch Problem reported by Sudhip Nashi (Bug#51857). * doc/posix-functions/lseek.texi (lseek): Mention macOS SEEK_DATA issue. * lib/lseek.c (rpl_lseek): Work around macOS portability glitch. * m4/lseek.m4 (gl_FUNC_LSEEK): Replace lseek on Darwin. * modules/lseek (Depends-on): Depend on msvc-nothrow and fstat only if needed. 2021-11-11 Fabrice Fontaine (tiny change) sigsegv: fix builds on microblazeel, or1k * m4/stack-direction.m4 (SV_STACK_DIRECTION): Assume it grows negative on microblaze* and or1k. 2021-11-09 Paul Eggert exclude: yield proper errno on failure * lib/exclude.c (add_exclude_file): Do not assume that fclose preserves errno on success. 2021-11-07 Paul Eggert regex: break regcomp.c link with glibc Problem reported by Bruno Haible in: https://lists.gnu.org/r/bug-gnulib/2021-11/msg00005.html * config/srclist.txt: Comment out regcomp.c for now. * lib/regcomp.c: Revert previous change. 2021-10-24 Bruno Haible string: Avoid syntax error re strdup in string.in.h (regr. 2021-09-07). Reported by Jan Engelhardt and by Arash Esbati via Andy Moreton in . * lib/string.in.h (_GL_ATTRIBUTE_DEALLOC, _GL_ATTRIBUTE_DEALLOC_FREE, _GL_ATTRIBUTE_MALLOC): Add fallback declarations, like in lib/stdlib.in.h. * lib/wchar.in.h (_GL_ATTRIBUTE_DEALLOC, _GL_ATTRIBUTE_DEALLOC_FREE, _GL_ATTRIBUTE_MALLOC): Likewise. 2021-10-19 Paul Eggert xalloc: new function xinmalloc * lib/xmalloc.c (xinmalloc): New function, which is like xnmalloc but for idx_t instead of size_t. 2021-10-18 Paul Eggert regex: fix buffer read overrrun * lib/regexec.c (re_search_internal): Fix buffer read overrun reported by Benno Schulenberg in: https://lists.gnu.org/r/bug-gnulib/2021-10/msg00035.html 2021-10-15 Paul Eggert nproc: port better to macOS 10.14 * lib/nproc.c (num_processors_ignoring_omp) [HAVE_SYSCTL && !defined __GLIBC__ && defined HW_NCPU]: Do not use a const mib, as macOS 10.14 rejects this. 2021-10-13 Paul Eggert sigsegv: fix quoting problem Problem reported for FreeBSD ports by Alexey Dokuchaev in: https://bugs.gnu.org/51144 * m4/stack-direction.m4 (SV_STACK_DIRECTION): Quote brackets. 2021-10-10 Paul Eggert nproc: port better to OpenBSD Problem reported by Omar Polo in: https://lists.gnu.org/r/emacs-devel/2021-10/msg00692.html * lib/nproc.c (num_processors_ignoring_omp): Prefer HW_NCPUONLINE to HW_NCPU, for OpenBSD. Also, make mib const. 2021-10-02 Paul Eggert timer-time: port better to OpenBSD 6.9 * m4/timer_time.m4 (gl_TIMER_TIME): Also require timer_settime to be declared, as it exists in OpenBSD but always fails with ENOSYS. sys_select: port better to OpenBSD 6.9 OpenBSD 6.9’s includes which then includes , which caused coreutils/lib/nproc.c compiles to fail with "/usr/include/signal.h:57: warning: 'struct sigaction' declared inside parameter list". Fix this. * lib/sys_select.in.h [__OpenBSD__]: Simply delegate to the system header if being included from . 2021-09-22 Bruno Haible doc: Fix outdated statement about Spanish collation.

In the former case, use the system strerror_r even on platforms like Android API level 23 that don’t have __xpg_strerror_r; also check for strerror_r failure just in case. * m4/error.m4 (gl_PREREQ_ERROR): * m4/strerror_r.m4 (gl_PREREQ_STRERROR_R): Use system extensions on Android, to avoid mishandling strerror_r on API level 23 and later. * modules/error, modules/strerror_r-posix (configure.ac): Surround gl_PREREQ_ERROR with AS_IF instead of plain if, so that AC_REQUIREs are propagated out. strerror_r-posix: port better to Android * m4/strerror_r.m4 (gl_FUNC_STRERROR_R): Move requirement of gl_USE_SYSTEM_EXTENSIONS from here ... (gl_FUNC_STRERROR_R_WORKS): ... to here, which is the macro that actually needs it. This avoids a bug where 'configure' tests whether strerror_r has the POSIX API before enabling GNU extensions. On Android, enabling GNU extensions switches from the POSIX to the GNU API.

Problem discovered when compiling diffutils 3.8 on RHEL 8.4 using a GCC 11.2.0 that I built myself. Perhaps the problem was not discovered earlier because the attribute works with ‘free’ (which is what I was seeing before on Fedora 34) but not with ‘rpl_free’ (seen on RHEL 8.4).

Arg is now either empty or nonempty (not a shell command) and is evaluated at m4 expansion time instead of at runtime; all callers changed. doc: clarify which module fixes 32-bit time_t * doc/posix-headers/time.texi: Make it clear that the 32-bit time_t problem is addressed by the year2038 module, not by the time module. 2021-07-01 Paul Eggert year2038: support glibc 2.34 _TIME_BITS=64 In glibc 2.34 on Linux kernels where time_t is traditionally 32-bit, defining _FILE_OFFSET_BITS=64 and _TIME_BITS=64 makes time_t 64-bit. Apps must define both macros. Gnulib applications that use either the largefile or the year2038 modules will want this behavior; largefile because it deals with the off_t and ino_t components of struct stat already, and so should also deal with time_t. * NEWS, doc/largefile.texi, doc/posix-headers/time.texi: Mention this. * m4/largefile.m4: Override two macros even in Autoconf 2.70 and later. (_AC_SYS_LARGEFILE_MACRO_VALUE): #undef $1 before #defining it, in case some other Gnulib macro has #defined it. (AC_SYS_LARGEFILE): Use AS_IF and AS_CASE to propagate AC_REQUIREs. Invoke gl_YEAR2038_BODY if we need to set _FILE_OFFSET_BITS=64. * m4/year2038.m4 (gl_YEAR2038_TEST_INCLUDES): New macro. (gl_YEAR2038_BODY): New macro, with gl_YEAR2038’s old body; this macro is designed to be used directly instead of being AC_REQUIREd. It takes an argument specifying whether 64-bit is required. Set _TIME_BITS=64 if this makes a difference in time_t width when setting _FILE_OFFSET_BITS=64. Do not warn about 32-bit time_t more than once. * modules/largefile (Files): Add year2038.m4. (Depends-on): Require gl_YEAR2038_EARLY. relocatable-prog-wrapper: add m4 files Add .m4 files needed for standalone relocatable-prog-wrapper, so that ‘./gnulib-tool --test relocatable-prog-wrapper’ does not fail with diagnostics like ‘configure.ac:63: error: possibly undefined macro: gl_FUNC_MALLOC_POSIX’. * modules/relocatable-prog-wrapper (Files): Add m4/free.m4, m4/malloc.m4, m4/mempcpy.m4, m4/rawmemchr.m4, m4/realloc.m4. 2021-06-28 Bruno Haible strerror-override: Fix possible compilation error.

(reallocarray): Use INT_MULTIPLY_WRAPV instead of xalloc_oversized, as it now suffices and is likely a bit more efficient (five fewer machine insns on Ubuntu 20.10 x86-64). * modules/reallocarray (Depends-on): Depend on intprops, not xalloc-oversized. Use conditional dependencies to avoid building realloc-gnu when not needed. reallocarray: don’t crash if item size is 0 This problem affects only platforms where xalloc_oversized divides a number by the size arg.

Make inclusion of bits/wordsize.h, bits/long-double.h dependent on __GLIBC__, not on !__WORDSIZE. * lib/libc-config.h: Use __attribute_nonnull__, not __attribute_maybe_unused__, to detect whether to include sys/cdefs.h. 2021-04-21 Paul Eggert realloc: port to AIX 7.1 * lib/realloc.c (_GL_USE_STDLIB_ALLOC): Do not define. This module relies on GNU malloc. This fixes a test failure on AIX 7.1. malloc: simplify * lib/malloc.c: Omit unnecessary "#undef malloc". I recently introduced it by mistake. This module defines _GL_USE_STDLIB_ALLOC and so malloc isn’t redefined to rpl_malloc. malloca: avoid ptrdiff_t overflow * lib/malloca.c: Include idx.h, intprops.h. (mmalloca): Check for ptrdiff_t overflow. Since this module uses _GL_USE_STDLIB_ALLOC, it cannot assume GNU malloc semantics. * modules/malloca (Depends-on): Add idx, intprops. careadlinkat: avoid ptrdiff_t overflow * lib/careadlinkat.c: Include idx.h, minmax.h. (readlink_stk): Avoid ptrdiff_t overflow in object allocation. Since this module uses arbitrary allocators (including stdlib_allocator), it cannot assume GNU malloc semantics. * modules/careadlinkat (Depends-on): Add idx, minmax. execute-tests: pacify compiler * tests/test-execute-main.c (main): Use 0x7DEADBEE rather than 0xDEADBEEF for nonces, to avoid provoking AIX XLC compiler warning that the latter is out of int range. 2021-04-20 Paul Eggert malloc-gnu-tests, etc.: use volatile for clang In some more test locations, store the result of malloc etc. into a volatile pointer so that clang doesn’t optimize away the malloc and thus bypass the test. This fixes a malloc-gnu test failure on macOS 11.2.3 with clang 12.0.0 on ARM. * tests/test-alloca-opt.c (do_allocation): * tests/test-malloc-gnu.c (main): * tests/test-malloca.c (do_allocation): * tests/test-realloc-gnu.c (main): * tests/test-reallocarray.c (main): * tests/test-aligned-malloc.c (main): * tests/test-aligned_alloc.c (main): Store malloc etc. results into a volatile pointer. 2021-04-18 Paul Eggert malloc-gnu-tests: pacify -Walloc-size-larger-than * tests/test-malloc-gnu.c (main): * tests/test-realloc-gnu.c (main): Hide true intentions from GCC, to prevent diagnostics like “warning: argument 1 value ‘9223372036854775808’ exceeds maximum object size 9223372036854775807 [-Walloc-size-larger-than=]”. safe-alloc: fix pointer implementation The old implementation assumed that all pointers use the same internal representation, but the C standard doesn’t guarantee this. Use void * (pointer) not void ** (pointer-to-pointer) for the internal functions’ API. The internal functions now return NULL if and only if they failed, and the macros translate that into -1 or 0 to satisfy the existing API. * doc/safe-alloc.texi (Safe Allocation Macros): Mention overflow. * lib/safe-alloc.c: Major rewrite. Now this simply defines SAFE_ALLOC_INLINE and includes safe-alloc.h. * lib/safe-alloc.h: Include stddef.h, not stdlib.h. (SAFE_ALLOC_INLINE): New macro; use Gnulib inline function style. (safe_alloc_realloc_n): New API, which passes and returns the pointer, and which returns NULL if and only if failure occurs. (safe_alloc_check): New function. (ALLOC, ALLOC_N, ALLOC_N_UNINITIALIZED, REALLOC_N): Redo using the new API for internal functions, and using calloc which is good enough since it’s GNU-compatible now. (FREE): Expand to an expression rather than merely to something that needs a following ‘;’ to become a statement. * modules/safe-alloc (Depends-on): Add calloc-gnu. calloc-gnu: now LGPLv2+ * modules/calloc-gnu (License): Change from GPL to LGPLv2+. The old value was evidently a longstanding typo, and calloc will be needed by LGPLv2+ modules that will want to rely on GNU behavior. safe-alloc: simplify via reallocarray * lib/safe-alloc.c: Do not include xalloc-oversized.h. (safe_alloc_alloc_n, safe_alloc_realloc_n): Use reallocarray to check for size or ptrdiff_t overflow. * modules/reallocarray (License): Switch from LGPL to LGPLv2+, as this is needed for safe-alloc and anyway is more appropriate for this library function common with BSD. * modules/safe-alloc (Depends-on): Depend on reallocarray rather than xalloc-oversized. xalloc-oversized: fix SIZE_MAX optimization bug * lib/xalloc-oversized.h (xalloc_count_t): Remove; no longer needed and was evidently error-prone anyway. (xalloc_oversized): Omit some over-optimization that caused SIZE_MAX to not be treated as too large (the Gnulib convention) on unusual platforms where PTRDIFF_MAX == SIZE_MAX. This change should not affect typical platforms where PTRDIFF_MAX < SIZE_MAX. When optimizing, simply use ptrdiff_t instead of xalloc_count_t. xalloc: new function xreallocarray This is the same as xnrealloc, which perhaps should be deprecated. The name xreallocarray should be easier to remember now that reallocarray is a standard GNU function. * lib/xalloc.h [GNULIB_XALLOC]: Do not include xalloc-oversized.h. (xnmalloc, xnrealloc, x2nrealloc): Simplify by using xreallocarray. * lib/xmalloc.c (xreallocarray): New function. * modules/xalloc (Depends-on): Add reallocarray; remove xalloc-oversized. group-member: simplify via realloc-gnu * lib/group-member.c, modules/group-member: Simplify similarly to backupfile. backupfile: simplify via realloc-gnu * lib/backupfile.c: Do not include xalloc-oversized.h. (numbered_backup): Simplify now that realloc will do the right thing about ptrdiff_t overflow. * modules/backupfile (Depends-on): Add realloc-gnu; remove xalloc-oversized. safe-alloc: improve doc * doc/safe-alloc.texi: Clarify that reallocating an array appends uninitialized storage. Say ‘sizeof *p’ rather than ‘sizeof(*p)’ which would need a space before the paren to follow GNU style. malloc-gnu-tests, etc.: test ptrdiff_t overflow * modules/calloc-gnu-tests (Depends-on): * modules/malloc-gnu-tests (Depends-on): * modules/realloc-gnu-tests (Depends-on): Add stdint. * tests/test-calloc-gnu.c (main): * tests/test-malloc-gnu.c (main):, * tests/test-realloc-gnu.c (main): Test for ptrdiff_t overflow. malloc-gnu, etc.: prefer AS_CASE to woolly AS_IF * m4/calloc.m4 (_AC_FUNC_CALLOC_IF): * m4/malloc.m4 (_AC_FUNC_MALLOC_IF): * m4/realloc.m4 (_AC_FUNC_REALLOC_IF): Use AS_CASE. malloc-gnu, etc.: sync better with Autoconf * m4/calloc.m4 (_AC_FUNC_CALLOC_IF): * m4/malloc.m4 (_AC_FUNC_MALLOC_IF): * m4/realloc.m4 (_AC_FUNC_REALLOC_IF): Avoid some unnecessary differences from Autoconf’s versions. Separate our platforms into a different line so that it’s easier to diff. Use AS_IF in case the args use AC_REQUIRE. However, don’t bother with omitting the first newline, as omitting the newline is not Gnulib style and the difference doesn’t seem to matter here. 2021-04-18 Bruno Haible malloc-posix, realloc-posix, calloc-posix: Document affected platforms. * doc/posix-functions/malloc.texi: Re-add platforms list. * doc/posix-functions/realloc.texi: Likewise. * doc/posix-functions/calloc.texi: Likewise. 2021-04-18 Bruno Haible More systematic file naming. * m4/ctype_h.m4: Renamed from m4/ctype.m4. * m4/threads_h.m4: Renamed from m4/threads.m4. * m4/uchar_h.m4: Renamed from m4/uchar.m4. 2021-04-18 Bruno Haible Add comments after 2021-04-11 change. * m4/*_h.m4: Add comments regarding *_REQUIRE_DEFAULTS and *_MODULE_INDICATOR macros. 2021-04-18 Bruno Haible doc: Update for FreeBSD 13.0/arm64. * doc/posix-headers/stdint.texi: Mention FreeBSD 13 bug. * m4/stdint.m4: Update comment. 2021-04-17 Paul Eggert xalloc: adjust to malloc ptrdiff_t change * lib/xmalloc.c (HAVE_GNU_CALLOC, HAVE_GNU_MALLOC, HAVE_GNU_REALLOC): Remove. (xmalloc, xrealloc, xcalloc): Simplify by assuming GNU behavior. * modules/xalloc (Depends-on): Add calloc-gnu, malloc-gnu, realloc-gnu. malloc, etc.: check for ptrdiff_t overflow In glibc 2.30 and later, malloc, realloc and calloc reject attempts to create objects larger than PTRDIFF_MAX bytes. This patch changes malloc-gnu etc. to support this behavior on non-GNU hosts. It also makes this change for malloc-posix etc. since it’s a safety measure that ought to be in POSIX (perhaps we can talk them into that...). In writing this patch I found a complicated set of code that had accumulated over the years, some written by yours truly. I got rid of the code I couldn’t see the need for nowadays. Among other things, the GNU realloc behavior is no longer incompatible with the C standard, because in C17 the latter was relaxed to allow the former. If I went too far in cleaning up, the old stuff can be resurrected. This change is mostly for 32-bit platforms, since practical 64-bit platforms cannot create objects larger than PTRDIFF_MAX bytes anyway. * doc/posix-functions/calloc.texi: * doc/posix-functions/malloc.texi: * doc/posix-functions/realloc.texi: Mention ptrdiff_t issues, and go into more detail about what the gnu extension module does. * doc/posix-functions/realloc.texi: Fix now-obsolete commentary about C99 vs glibc, as C17 allows the glibc behavior and POSIX will follow suit when it gets around to it. * lib/calloc.c, lib/malloc.c, lib/realloc.c: Simplify by always supplying a GNU-compatible version, as that suffices for correctness and is good enough for performance. Include xalloc-oversized.h, and use xalloc_oversized to check for ptrdiff_t overflow. (NEED_CALLOC_GNU, NEED_MALLOC_GNU, NEED_REALLOC_GNU): Remove. * m4/calloc.m4 (_AC_FUNC_CALLOC_IF): * m4/malloc.m4 (_AC_FUNC_MALLOC_IF): * m4/realloc.m4 (_AC_FUNC_REALLOC_IF): Don’t start with a newline.

It’s not worth the aggravation of maintaining these, as they are confusing (they don’t really mean GNU-compatible anyway). Don’t bother testing for GNU behavior if we have already decided to replace the function, since the replacement is always GNUish. * m4/calloc.m4 (gl_FUNC_CALLOC_POSIX): * m4/realloc.m4 (gl_FUNC_REALLOC_POSIX): Defer to gl_FUNC_MALLOC_POSIX. * m4/malloc.m4 (gl_FUNC_MALLOC_PTRDIFF, gl_CHECK_MALLOC_PTRDIFF): New macros.

This fixes a typo that I introduced in 2011-04-08T18:39:01Z!eggert@cs.ucla.edu. Apparently nobody uses Gnulib realloc in that way? 2021-04-07 Bruno Haible execute tests: Avoid test failure in certain environments. Reported by Dmitry V. Levin in . * tests/test-execute-main.c (main): Close file descriptors 3..19. * tests/test-execute-child.c (main): Remove NetBSD workaround. * modules/execute-tests (configure.ac): Test for close_range function. 2021-04-07 Paul Eggert utimens: fix confusing arg type in internal func Although the old code was technically correct, this was accidental and it confused a GCC 11 prerelease. Reported by Ondrej Dubaj in: https://lists.gnu.org/r/bug-tar/2021-04/msg00000.html * lib/utimens.c (update_timespec): Change arg type from ‘struct timespec *[2]’ (pointer to array of 2 pointers to timespecs) to ‘struct timespec **’ (pointer to pointer to the first timespec in an array of 2 timespecs). Although the old code happened to be technically correct, it was misleading and confused Coverity. And though the type ‘struct timespec (**)[2]’ (pointer to pointer to array of 2 timespecs) would perhaps be more technically correct, it would be almost as confusing and would require changes elsewhere in this file; let’s quit while we’re ahead. xalloc: simplify integer overflow test * lib/xalloc.h (x2nrealloc): Simplify integer overflow detection. This is easier to maintain, and (unlike the old code) exact. 2021-04-06 Paul Eggert group-member: minor tweak to omit a * * lib/group-member.c: Include intprops.h. (get_group_info): Use INT_MULTIPLY_WRAPV instead of xalloc_oversized (which does a multiplication) followed by the same multiplication. The code was OK as-is; this is just conceptual simplification, possible now that we have xalloc_count_t. * modules/group-member: Depend on intprops. backupfile: less-aggressive buffer growth * lib/backupfile.c: Include intprops.h. (numbered_backup): Grow buffer by the usual 50%, not 100%. This is easier to do now that we have xalloc_count_t. * modules/backup-rename, modules/backupfile: Depend on intprops. xalloc-oversized: export xalloc_count_t * lib/xalloc-oversized.h (__xalloc_oversized, xalloc_oversized): * lib/xmalloca.h (nmalloca): Comment re restrictions on arg types. * lib/xalloc-oversized.h (xalloc_count_t): Rename from __xalloc_count_type; all uses changed. This publicizes the type. 2021-04-05 Paul Eggert xalloc: try to pacify gcc -Wsign-compare Problem reported by Marc Nieper-Wißkirchen in: https://lists.gnu.org/r/bug-gnulib/2021-04/msg00034.html * lib/xmalloc.c (xpalloc): For odd platforms where SIZE_MAX < IDX_MAX, use a tricky destination for INT_MULTIPLY_WRAPV instead of an explicit comparison to SIZE_MAX. This should be more likely to pacify gcc -Wsign-compare. 2021-04-05 Marc Nieper-Wißkirchen hamt: Fix coding errors. Reported by Bruno Haible in after a Coverity run. * lib/hamt.c (bucket_do_while, hamt_iterator): Add missing derefencing operator and silence a bogus warning on uninitialized variables. * tests/test-hamt.c (test_general): Replace two errorneous assignment operators with comparison operators. 2021-04-05 Fabrice Fontaine pthread-cond: Fix compilation error. * lib/pthread-cond.c (pthread_cond_wait): Use tv.nsec instead of tv.usec. 2021-04-04 Fabrice Fontaine pthread-cond: Fix wrong configure results when is absent. * m4/pthread-cond.m4 (gl_PTHREAD_COND): When does not exist, set HAVE_PTHREAD_COND_* to 0, not to 1. 2021-04-04 Bruno Haible backupfile, backup-rename: Trim dependencies. * lib/backupfile.h: Add comment. * lib/backupfile.c: Include , for readdir() declaration. * modules/backup-rename (Depends-on): Remove dirent-safer, fcntl. Add fcntl-h. * modules/backupfile (Depends-on): Likewise. Remove xalloc. Add xalloc-die. 2021-04-04 Bruno Haible doc: Fix syntax error (regression from 2021-04-02). * doc/posix-functions/strtol.texi: Put @item inside @itemize block. 2021-04-04 Marc Nieper-Wißkirchen hamt: Document the module in the Gnulib manual. Suggested by Bruno Haible in . * doc/containers.texi: Add a subsection to section 15.11 Container data types. * lib/hamt.h: Improve documentation on how Hamt_entry is supposed to be used. 2021-04-03 Paul Eggert savedir: avoid unlikely undefined behavior * lib/savedir.c (streamsavedir): Prefer idx_to size_t where either will do. Simplify reallocation of entries. Use xpalloc to reallocate name_space, to avoid some unlikely integer overflows. quotearg: avoid undefined and/or O(N**2) Avoid undefined and O(N**2) behavior in some very unlikely cases. * lib/quotearg.c (quotearg_n_options): Document that N must be less than MIN (INT_MAX, IDX_MAX), and add this to the abort test; this also avoids a conditional branch. Use xpalloc instead of xrealloc, to avoid O(N**2) behavior in very-unlikely cases. xgethostname: reorganize / simplify xgethostname and xgetdomainname were essentially copies long ago, but they’ve diverged. Bring them back together again by implementing the (rarely used) latter in terms of the former. And avoid some unnecessary realloc calls while we’re at it. * lib/xgetdomainname.c: Rewrite from scratch so that it merely includes xgethostname.c with a few preliminaries. * lib/xgethostname.c: Generalize so that it can be included from xgetdomainname.c. (GETANAME, XGETANAME): New macros. (INITIAL_HOSTNAME_LENGTH): Remove. No need for this parameter. Use 100 instead, as few hostnames are longer than that. (XGETANAME): Try getting the hostname into the stack first, as that avoids a malloc call in the usual case. Check for both POSIX-style truncation and SunOS 5.5 bug in a cleaner way, by simply checking string length. Don’t use x2realloc, which wastes time preserving buffer garbage; use xpalloc with NULL instead. Don’t bother shrinking buffer in the very rare case where the hostname is longer than sizeof buf; it’s not worth the aggravation. * modules/xgetdomainname (Depends-on): Remove free-posix, xalloc. Add xgethostname. 2021-04-03 Bruno Haible *-list tests: Add more tests. * tests/test-array_list.c (check_equals_by_forward_iteration, check_equals_by_backward_iteration): New functions.

The link fails due to missing definitions of pthread_mutex_lock and pthread_mutex_unlock. GNU Tar uses unlocked-io and so should not need to worry about multithreading or locks. * lib/mbtowc-lock.h (mbtowc_with_lock) [USE_UNLOCKED_IO]: Don’t bother with locks, since this app is single-threaded. There may be similar linking problems with lib/nl_langinfo.c and lib/setlocale_null.c but my GNU Tar build didn’t run into them, so I left them alone for now. 2021-03-01 Paul Eggert unlocked-io: do not redefine getc_unlocked etc. I ran into this problem on AIX 7.1 with GNU Tar, which enables visibility of getc_unlocked etc. after testing whether they’re declared, causing argp-namefrob.h and unlocked-io.h to redefine the macros. * lib/argp-namefrob.h, lib/unlocked-io.h: (clearerr_unlocked, feof_unlocked ferror_unlocked) (fflush_unlocked, fgets_unlocked, fputc_unlocked, fputs_unlocked) (fread_unlocked, fwrite_unlocked, getc_unlocked, getchar_unlocked) (putc_unlocked, putchar_unlocked): Do not define if already defined. parse-datetime2: new module This splits the old parse-datetime into two parts; the first is parse-datetime2 which supports all the new bells and whistles, the second is parse-datetime, which reverts to its original intent. This avoids some bogus diagnostics when build GNU Tar with gcc -flto -fanalyze and with --enable-gcc-warnings. And it slims down the executable a bit. * NEWS: Mention this. * lib/parse-datetime.y (parser_control) [!GNULIB_PARSE_DATETIME2]: Omit parse_datetime_debug member. (debugging): New function.

After these changes, build_trtable’s total stack allocation is only 20 KiB on a 64-bit machine, and this is less than glibc’s 64 KiB cutoff so there’s little point to using alloca to shrink it. Although Gnulib traditionally has used a 4 KiB cutoff, going to 20 KiB here should not be a significant problem in practice; Gnulib-using packages concerned about overflow of tiny stacks can compile with something like gcc -fstack-clash-protection. scratch_buffer: add scratch_buffer_dupfree macro * lib/scratch_buffer.h (__libc_scratch_buffer_dupfree): New macro, needed to support recent changes in this module. regex: remove alloca usage on regex set_regs Derived from this patch by Adhemerval Zanella: https://sourceware.org/pipermail/libc-alpha/2021-January/121372.html * lib/regex_internal.h: Include dynarray.h, for Gnulib. * lib/regexec.c (DYNARRAY_STRUCT, DYNARRAY_ELEMENT) (DYNARRAY_PREFIX): New macros.

Invoke gl_STDLIB_MODULE_INDICATOR. 2020-12-17 Paul Eggert canonicalize-lgpl: fix AIX test failures This merges the recent canonicalize.c fix into canonicalize-lgpl.c. Problem reported by Bruno Haible in: https://lists.gnu.org/r/bug-gnulib/2020-12/msg00138.html * lib/canonicalize-lgpl.c: Include sys/stat.h. (__realpath): When testing a file name ending in '/', use stat rather than readlink, so that it does the right thing on AIX. * modules/canonicalize-lgpl (Depends-on): Add stat, sys_stat. canonicalize: omit second readlink when not needed * lib/canonicalize.c (canonicalize_filename_mode_stk): Omit second readlink when (can_exist != CAN_MISSING && startlen != 0 && !logical). Simplify. canonicalize: remove arbitrary 8192-byte limit Remove canonicalize.c’s arbitrary 8192-byte limit on platforms like GNU Hurd that do not define the PATH_MAX macro, and similarly for canonicalize-lgpl.c’s arbitrary 1024-byte limit. Do this by using scratch buffers. Lessen the number of differences between the two source files, to simplify this and future maintenance. * lib/canonicalize-lgpl.c (__realpath): * lib/canonicalize.c (canonicalize_filename_mode_stk): Use scratch buffers instead of malloc and malloca. This avoids the need for alloca, and avoids the need for malloc in most cases. * lib/canonicalize-lgpl.c, lib/canonicalize.c: Make these files easier to compare, e.g., by sorting include files and by switching to the GNU convention of calling file names "file names", not "path names". Include stdbool.h, scratch_buffer.h. * lib/canonicalize-lgpl.c (IDX_MAX) [_LIBC]: New macro. (malloca) [_LIBC]: Remove. [!_LIBC]: Do not include malloca.h. (get_path_max): New function, so that pathconf is called only in the rare and dubious case when when RESOLVED is not null and PATH_MAX is not defined. Invoke pathconf on "/" not the input file name, as we care about the longest file name starting from "/" (not from the input file name), and POSIX does not specify what pathconf does on a non-directory file anyway. If PATH_MAX is not defined, do not worry about overriding a path_max of 0, and do not let path_max exceed IDX_MAX. (__realpath): Remove an assumption that file name components cannot exceed 1024 bytes when PATH_MAX is not defined (wrong for the Hurd, presumably). When allocating the result, allocate it to just the right size; this costs nothing when the result is smaller than 1023 bytes, and for larger results it's probably worth the CPU to call realloc, as canonicalize.c already does. * lib/canonicalize.c: Include attribute.h. Do not include pathmax.h or xgetcwd.h. (PATH_MAX): Do not define, so file names longer than 8192 bytes work on platforms with no fixed limit. (canonicalize_filename_mode_stk): New function, with the content of the old canonicalize_filename_mode. Use getcwd instead of xgetcwd, and readlink instead of areadlink, since the scratch buffers now do memory management for us. Use rawmemchr instead of adding strlen. Use mempcpy instead of mempcpy + size. Assume free preserves errno. (canonicalize_filename_mode): Use it. * modules/canonicalize (Depends-on): Remove areadlink, pathmax, xgetcwd. Add attribute, free, getcwd, mempcpy, rawmemchr, scratch_buffer, stdbool, xalloc-die. * modules/canonicalize-lgpl (Depends-on): Remove alloca-opt, malloca, realloc-posix. Add scratch_buffer, stdbool. canonicalize-lgpl: simplify merge to glibc This patch lessens the differences between git glibc stdlib/canonicalize.c and lib/canonicalize-lgpl.c. The (perhaps wishful) goal is to make them identical. * lib/canonicalize-lgpl.c [!_LIBC]: Include , not config.h. Omit an unnecessary (!HAVE_CANONICALIZE_FILE_NAME || !FUNC_REALPATH_WORKS || defined _LIBC) #if. Do not include alloca.h, since we use malloca now. [_LIBC]: Include , and define dummy macros FILE_SYSTEM_PREFIX_LEN, IS_ABSOLUTE_FILE_NAME, ISSLASH, malloca, freea so that the mainline code can be kept #ifdef free. [!_LIBC]: Remove dummy macros for SHLIB_COMPAT, versioned_symbol, compat_symbol, weak_alias, __set_errno since libc-config.h does that. Add redirecting macros __mempcpy, __pathconf, __rawmemchr, __eloop_threshold. All uses of their definiens changed. (SIZE_MAX): Remove; no longer needed. (alloc_failed): Remove, and remove all instances. No need for alloc_failed now that free preserves errno. (__realpath): Default path_max to 1024 instead of 8192, as that’s the glibc tradition and is safer when the 2nd argument is null. Use __rawmemchr instead of strchr. Use __mempcpy where appropriate. Simplify test for overflow so that it does not need SIZE_MAX. Do not preserve errno around free or freea calls; no longer needed. Mark __realpath with libc_hidden_def. * modules/canonicalize-lgpl (Depends-on): Add free, libc-config, malloc-posix, mempcpy, realloc-posix, rawmemchr. * modules/free: Now LGPLv2+, for canonicalize-lgpl. free: preserve errno * lib/free.c (rpl_free): Preserve errno. Check for null only if CANNOT_FREE_NULL is defined, as an optimization for POSIX 2008 platforms that do not preserve errno. * m4/free.m4 (gl_FUNC_FREE): Check whether free preserves errno. Also, define CANNOT_FREE_NULL if free cannot free NULL. * modules/free (configure.ac): Also replace 'free' if it does not preserve errno. idx: simplify IDX_MAX, remove IDX_WIDTH * lib/idx.h (IDX_MAX): Simplify by removing obsolete reference to UNSIGNED_IDX_T. (IDX_WIDTH): Remove, since it’s not used and its value arguably should be PTRDIFF_WIDTH anyway. 2020-12-16 Bruno Haible posix_spawn_file_actions_addfchdir-tests: Rename test. * tests/test-posix_spawn-fchdir.c: Renamed from tests/test-posix_spawn5.c. * modules/posix_spawn_file_actions_addfchdir-tests (Files, Makefile.am): Update. posix_spawn_file_actions_addchdir-tests: Rename test. * tests/test-posix_spawn-chdir.c: Renamed from tests/test-posix_spawn4.c. * modules/posix_spawn_file_actions_addchdir-tests (Files, Makefile.am): Update. posix_spawn-tests: Rename test. * tests/test-posix_spawn-open1.c: Renamed from tests/test-posix_spawn3.c. * modules/posix_spawn-tests (Files, Makefile.am): Update. posix_spawnp-tests: Rename test. * tests/test-posix_spawn-dup2-stdin.c: Renamed from tests/test-posix_spawn2.c. * tests/test-posix_spawn-dup2-stdin.in.sh: Renamed from tests/test-posix_spawn2.in.sh. * modules/posix_spawnp-tests (Files, Makefile.am): Update. posix_spawnp-tests: Rename test. * tests/test-posix_spawn-dup2-stdout.c: Renamed from tests/test-posix_spawn1.c. * tests/test-posix_spawn-dup2-stdout.in.sh: Renamed from tests/test-posix_spawn1.in.sh. * modules/posix_spawnp-tests (Files, Makefile.am): Update. 2020-12-14 Bruno Haible findprog-in: Allow overriding the current directory. * lib/findprog.h (find_in_given_path): Add directory argument. * lib/findprog-in.c (find_in_given_path): Likewise. * lib/execute.c (execute): Update caller. * lib/spawn-pipe.c (create_pipe): Likewise. * lib/windows-spawn.c (spawnpvech): Likewise. * NEWS: Mention the change. 2020-12-14 Bruno Haible posix_spawn-internal: Make better use of 'const'. * lib/spawn_int.h (__spawni): Does not need write access to the elements of argv and envp. * lib/spawni.c (__spawni, script_execute): Likewise. * lib/spawn.c (posix_spawn): Update caller. * lib/spawnp.c (posix_spawnp): Likewise. 2020-12-14 Bruno Haible spawn: Make it compile on native Windows. * modules/spawn (Depends-on): Add signal-h. 2020-12-14 Bruno Haible windows-spawn: Avoid shadowing a variable. * lib/windows-spawn.c (spawnpvech): Rename local variable 'flags'. 2020-12-13 Paul Eggert string: port memchr macro to AIX 7.2 XLC Its defines a memchr macro to help inlining. * lib/string.in.h (memchr): #undef before #defining. canonicalize: fix AIX test failures Problem reported by Bruno Haible in: https://lists.gnu.org/r/bug-gnulib/2020-12/msg00109.html * lib/canonicalize.c (canonicalize_filename_mode): When testing a file name ending in '/', use stat rather than readlink, so that it does the right thing on AIX. * modules/canonicalize (Depends-on): Add readlink, to pull in the recent changes in the Gnulib readlink module.

(SIZE_MAX): Remove. (save_abbr): Put string length into a ptrdiff_t variable, so that the size comparison works naturally. This fixes CVE-2017-7476 in a cleaner way. parse-datetime: streamline overflow checking When parse-datetime.y’s overflow code was written, INT_ADD_WRAPV did not work for unsigned destinations, and since time_t might be unsigned that meant it did not work for time_t destinations. This limitation of INT_ADD_WRAPV has been fixed, so we can now streamline parse-datetime.y a bit. * lib/parse-datetime.y: Do not include limits.h, as LONG_MAX has not been used for a while. (yylex, parse_datetime2): Assume C99 declarations after statements. (yyles): Use INT_SUBTRACT_WRAPV instead of an explicit comparison to TYPE_MINIMUM. (parse_datetime2): No need for time_overflow now that INT_ADD_WRAPV works for unsigned results. parse-datetime-tests: port to Alpine Linux 3.12.1 * tests/test-parse-datetime.c: Include errno.h for errno, and unistd.h for _SC_TZNAME_MAX and sysconf.

Exit if we can't revert it. 2020-09-25 Paul Eggert regex-tests: fix possible Turkish false-alarm * modules/regex-tests (Depends-on): Add wctype-h. * tests/test-regex.c: Include wctype.h. (main): Check that ‘i’ uppercases to ‘İ’ in Turkish, as the Turkish regex test assumes this. regex-tests: fix test and add debug output Perhaps this will fix the recent grep test failure reported at: https://buildfarm.opencsw.org/buildbot/builders/ggrep-solaris10-sparc/builds/199 At least, the debug output should help narrow down the failure. * tests/test-regex.c: Include stdarg.h, stdio.h. (exit_status): New var. (report_error): New function. (main): Use it to report failures to stdout instead of merely exiting with some nonzero status. The status info alone isn’t enough to do remote debugging. In the new tr_TR.UTF-8 test, clear regex before calling re_compile_pattern, fixing a portability bug. regex: no longer match glibc * config/srclist.txt: Comment out regex_internal.c for now. 2020-09-23 Paul Eggert regex: fix ignore-case Turkish bug * lib/regex_internal.c (build_wcs_upper_buffer): Do not assume that converting single-byte character to upper yields a single-byte character. This is not true for Turkish, where towupper (L'i') yields L'İ', which is not single-byte. * tests/test-regex.c (main): Test for this bug. regex: port to weird isascii platforms * lib/regex_internal.h (isascii) [!_LIBC]: Supply glibc version. 2020-09-20 Norihiro Tanaka dfa: make dfasupported a global function * lib/dfa.c (dfasupported): Rename, and make it global.

(die, c_stack_action): Assume C99. * modules/c-stack (Depends-on): Add c99, mempcpy. c-stack: improve checking if !libsigsegv If SIGINFO_WORKS, do not treat a null pointer dereference as if it were a stack overflow. Use uintptr_t and INT_ADD_WRAPV to avoid unlikely pointer overflow. Also, fix some obsolete code and typos. I found these problems while looking into this bug report: https://lists.gnu.org/r/grep-devel/2020-09/msg00053.html * lib/c-stack.c: Include c-stack.h first, to test interface. Include inttypes.h for UINTPTR_MAX, stdbool.h, stddef.h for max_align_t, intprops.h for INT_ADD_WRAPV. (USE_LIBSIGSEGV): New macro; use it to simplify later code. (SIGSTKSZ): Simplify setup. Work around libsigsegv bug only for libsigsegv 2.8 and earlier since the bug should be fixed after that. (alternate_signal_stack): Use max_align_t instead of doing it by hand. (segv_handler, overflow_handler, segv_handler) [DEBUG]: Assume sprintf returns byte count; this assumption is safe now. (page_size): New static volatile variable, since sysconf isn’t documented to be async-signal-safe on Solaris. This variable is present and used if (!USE_LIBSIGSEGV && HAVE_SIGALTSTACK && HAVE_DECL_SIGALTSTACK && HAVE_STACK_OVERFLOW_HANDLING && SIGINFO_WORKS). (segv_handler): Use it if present. Never report null pointer dereference as a stack overflow. Check for (unlikely) unsigned and/or pointer overflow. * m4/c-stack.m4 (AC_SYS_XSI_STACK_OVERFLOW_HEURISTIC): Rename cache variables to gl_cv_sys_stack_overflow_works and gl_cv_sys_xsi_stack_overflow_heuristic. All uses changed. (gl_PREREQ_C_STACK): Do not require AC_FUNC_ALLOCA, since c-stack no longer uses STACK_DIRECTION. Do not check for unistd.h, since we depend on unistd. Fix shell typo ‘$"ac_cv_sys_xsi_stack_overflow_heuristic"’. * modules/c-stack (Depends-on): Sort.

Problem reported by Jeffrey Walton in: https://lists.gnu.org/r/bug-gnulib/2019-07/msg00058.html The GCC 3.3.4 documentation says the attribute should work, but apparently it does not work on Ubuntu 4’s GCC 3.3. There seems little point or desire to research this circa-2004 platform further, so just avoid the attribute there. 2020-09-17 Jim Meyering test-dfa-match.sh: port timeout work-around to newer Busybox * tests/test-dfa-match.sh: Update timeout -t portability test to accommodate Busybox 1.30.0 and newer. 2020-09-16 Paul Eggert fnmatch: adjust to match glibc fix This fixes handling of collating symbols in fnmatch (glibc bug 26620). This does not affect Gnulib; it merely keeps Gnulib and glibc closer together, to help with any eventual merge, by incorporating a recent glibc patch. The patch and the following commentary is by Andreas Schwab. * lib/fnmatch_loop.c (FCT) [WIDE_CHAR_VERSION]: The variable idx contains the index into the extra array, whereas wextra points into the extra array at this index, containing the length of the following collating sequence in the wide character representation. 2020-09-16 Bruno Haible stat, fstat: Fix compilation error with old mingw headers.

This reverts 2020-09-14T01:20:01Z!eggert@cs.ucla.edu, which is no longer neeeded now that 2020-09-14T13:21:05Z!noritnk@kcn.ne.jp fixed the underlying problem. 2020-09-13 Paul Eggert dfa: avoid use of uninitialized constraint * lib/dfa.c (merge_nfa_state): Do not initialize the constraint to zero here. (dfaoptimize): Do it here instead, via xcalloc. This prevents the use of an uninitialized constraint by later code when ! (flags[i] & OPT_QUEUED) means merge_nfa_state was not called to initialize the constraint. Problem found by running 'valgrind src/grep -E '(^| )*(a|b)*(c|d)*( |$)' < /dev/null' on Ubuntu 18.04.5 x86-64. dfa: assume C99 in reorder_tokens * lib/dfa.c (reorder_tokens): Assume C99 and simplify. dfa: fix dfa-heap-overrun failure * lib/dfa.c (reorder_tokens): When setting map[d->follows[i].elems[j].index], instead of incorrectly assuming that (i < d->follows[i].elems[j].index), use two loops, one to set the map array and the other to use it. The incorrect assumption caused some elements to be missed, and this in turn caused grep's dfa-heap-overrun test to fail on Solaris 10 sparc when compiled with GCC. I found this bug while investigating https://buildfarm.opencsw.org/buildbot/builders/ggrep-solaris10-sparc/builds/183 and I think the bug also occurs on GNU/Linux but with more-subtle symptoms. The bug predates the recent dfa.c changes; perhaps the recent changes make the bug more likely. 2020-09-13 Bruno Haible parse-datetime: Make the build rule work with parallel 'make'. Reported by Daiki Ueno in . * modules/parse-datetime (Makefile.am): Use a phony target and the general idiom for rules that produce multiple files. 2020-09-13 Ben Pfaff getpass: Check for nonnull prompt argument while avoiding warnings. * lib/getpass.c (_GL_ARG_NONNULL): Define to empty. (getpass) [!_WIN32]: Print prompt only if nonnull. 2020-09-12 Paul Eggert dfa: epsilon-closure tweaks (Bug#40634) Rename BACKWORD to BACKWARD consistently. * lib/dfa.c (struct dfa): Reorder members to reduce fragmentation. (addtok_mb): Redo slightly to make it act more like a state machine. Check depth only when it increases. (epsclosure): Let the switch test the tokens. (dfaanalyze): Cache tindex. Simplify position loops. Prefer xcalloc to xnmalloc + explicit zeroing. Free BACKWARD only if it is not null, since we're testing that anyway. (dfaanalyze, build_state): Use merge2 instead of doing it by hand. 2020-09-12 Norihiro Tanaka dfa: use backward set in removal of epsilon closure When removing in epsilon closure, the code searched all nodes sequentially, and this was slow for some cases. Build a backward set before search, and only check previous position with the set. Problem reported in . * lib/dfa.c (struct dfa): New member 'epsilon'. (addtok_mb): Check whether a pattern has epsilon node or not. (epsclosure): New arg BACKWORD; caller changed. When removing epsilon node and reconnecting, check only previous positions. Treat BEG as if it were character. (dfaanalyze): Build backward set. 2020-09-10 Paul Eggert canonicalize: fix pointer indexing bugs Problem reported by Florian Weimer in: https://lists.gnu.org/r/bug-gnulib/2020-09/msg00025.html * lib/canonicalize-lgpl.c (__realpath): * lib/canonicalize.c (canonicalize_filename_mode): Do not generate a pointer past the end of the array. * lib/canonicalize.c (canonicalize_filename_mode): Do not use a pointer after passing it to realloc. 2020-09-09 Paul Eggert tempname: help merge with glibc Inspired by draft patches by Adhemerval Zanella in: https://sourceware.org/pipermail/libc-alpha/2020-September/117501.html https://sourceware.org/pipermail/libc-alpha/2020-September/117502.html * lib/tempname.c: Include stdalign.h, time.h.

Include libc-config.h instead of config.h. Include alloca.h only if _LIBC || HAVE_ALLOCA. Do not include "../locale/elem-hash.h" if _LIBC. Define macros for btowc, etc. if _LIBC. All uses simplified. Define FALLTHROUGH if _LIBC, instead of including attribute.h. Include intprops.h, since glibc has it now. (SIZE_MAX): Remove; use (size_t) -1 instead.

Remove alloca. 2020-05-31 Bruno Haible getrandom: Doc and test tweaks. * lib/getrandom.c (getrandom): Mention that it never returns 0, and that it sets errno when failing. * tests/test-getrandom.c (main): Disable the high-quality check on those platforms on which it fails. * doc/glibc-functions/getrandom.texi: Add Minix, AIX, HP-UX, IRIX, Cygwin to the list of platforms that don't have the function.

The fields source, target, mntroot and fstype may contain characters like '\r'; sscanf(3) fails to read such values with the %s format specifier because it would stop at such characters. Example: "mount -t tmpfs tmpfs /foo^Mbar". The only true separator in that file is the ' ' character. 2. The source field may be an empty string, which happens e.g. with "mount -t tmpfs '' /target". 3. The fstype field may contain mangled characters as well which need unescaping. * lib/mountlist.c (terminate_at_blank): Add utility function. (read_file_system_list): In the block trying to read the mountinfo file, avoid using sscanf(3) with %s format; instead, parse the above fields separated by spaces one by one. This also handles the case when the source field is an empty string. Unescape the fstype field. 2019-04-09 Bruno Haible openmp: Add workaround for 32-bit programs on AIX. * lib/omp.in.h: New file. * lib/omp-init.c: New file, based on lib/nproc.c. * m4/omp_h.m4: New file. * modules/openmp (Files): Add them.

Also, using xtime_t instead of float preserves the precision. Suggested by Bruno Haible. * lib/xtime.h (xtime_make): Handle overflows of nanoseconds. * modules/timevar (Depends-on): We need gethrxtime. We no longer use times(). (Link): Update. * lib/timevar.h (timevar_time_def): Use xtime_t. * lib/timevar.c (set_to_current_time): Use gethrxtime.

See https://lists.gnu.org/archive/html/bug-gnulib/2018-10/msg00040.html. * lib/timevar.c (timevar_print): Use %7.3f for usr/sys and %11.6f for wall, since its resolution is much higher. 2018-10-13 Akim Demaille timevar: expect that getrusage is available. Don't keep both times and getrusage as backend: both are guaranteed by gnulib, a single one suffices. Using getrusage is open to possibly tracking other types of resources in the future. * modules/timevar (Depends-on): Add getrusage. (configure.ac): Remove gl_TIMEVAR. (Files): Remove m4/timevar.m4. * m4/timevar.m4: Remove, rely on gnulib for getrusage. * lib/timevar.h (timevar_enabled): Clarify documentation. * lib/timevar.c: Remove all the code about times. Remove all the CPP guards about getrusage: expect it to be present (courtesy of gnulib). 2018-10-12 Bruno Haible mountlist: Improve support for Solaris in 64-bit mode. Reported by David Wood in . * m4/ls-mntd-fs.m4 (gl_LIST_MOUNTED_FILE_SYSTEMS): On Solaris 8 or newer, define MOUNTED_GETEXTMNTENT instead of MOUNTED_GETMNTENT2. * lib/mountlist.c: Add code for MOUNTED_GETEXTMNTENT case. 2018-10-12 Bruno Haible mountlist: Add support for Minix.

We don’t need to worry about binary compatibility in Gnulib, and the old way of doing things had a hole in the user options that caused FTS_OPTIONMASK to not work as desired. 2018-10-08 Bernhard Voelker fts: remove FTS_NOATIME This reverts commit da4d6974013c822af1498941e32db774b2031765. We cannot guarantee that O_NOATIME works: e.g. openat fails with EPERM if the effective user ID of the caller does not match the owner of the file and the caller is not privileged. Downstream findutils has never picked up FTS_NOATIME. Discussed at . * lib/fts_.h (FTS_NOATIME): Remove bit flag. (FTS_OPTIONMASK): Adjust. * lib/fts.c (diropen, fts_open, fts_build): Likewise.

Use change. dfa: tweak allocation performance * lib/dfa.c (merge_nfa_state, dfaoptimize): Prefer ptrdiff_t for indexes some more. Use char for flags, as it’s wide enough. Allocate queue and flags together, with one malloc call. No need to use xnmalloc since the multiplication and addition cannot overflow (it’s already been checked by earlier allocation). Prefer memset to open-coding. dfa: prune states as we go * lib/dfa.c (prune): Remove. dfa: reorder enum for efficiency (merge_nfa_state): Prune as we go instead of at the end. Prefer ptrdiff_t for indexes, as this helps the compiler a bit. * lib/dfa.c (END): Now -1 again. Reorder other elements of the enumeration to make it easier for GCC to generate efficient code by using fewer comparisons to check for ranges of values. (atom): Take advantage of the reordering. 2018-09-18 Norihiro Tanaka dfa: optimize alternation in NFA Even when similar states exist in alternation, the DFA treats them as separate items, which may complicate the transition in NFA and cause slowdown. This change assembles the states into one. For example, ab|ac is changed into a(b|c). This change speeds-up matching for many branched patterns. For example, grep speeds up more than 30× in: seq 10000 | sed 's/$/ abcdefghijklmnopqrstuvwxyz/; s/$/./' >in time -p env LC_ALL=C grep -vf in in * lib/dfa.c (prune): New function. (merge_nfa_state): New function. It merges similar NFA states. (dfaoptimize): New function. It seeks merged and removed nodes. (dfaanalyze): Call new function. (dfautf8noss): Change name from dfaoptimize because of addition of new function. (dfacomp): Update caller. dfa: simplify initial state Simplifying the initial state enables easier optimization of the NFA. * lib/dfa.c (enum token): Add new element BEG. (prtok): Adjust due to adding element BEG. (dfaparse): Put BEG at a head of tokens. (state_index): Adjust due to adding element BEG. (dfaanalyze): Concatenate BEG to other tokens, and simplify to build initial state. (dfamust): Adjust due to adding element BEG.

Reported by Daniel P. Berrangé in https://lists.gnu.org/archive/html/bug-gnulib/2018-07/msg00061.html. * m4/ffs.m4 (gl_FUNC_FFS): Check whether ffs() not only exists but is also declared. 2018-07-13 Paul Eggert regex-tests: add dependency * modules/regex-tests (Depends-on): Add gettext-h. This is needed given the recent changes to regex, which no longer depends on gettext-h. 2018-07-06 Paul Eggert regex: now in sync with glibc * config/srclist.txt: Gnulib and glibc regex code are synchronized again. 2018-07-05 Paul Eggert renameatu: rename from renameat2 It's looking like Glibc will add a renameat2 function that is incompatible with Gnulib renameat2; see: https://sourceware.org/ml/libc-alpha/2018-07/msg00064.html To help avoid future confusion, rename renameat2 to something else. Use the name 'renameatu', as the Gnulib function is close to the Glibc function. Perhaps someday there will also be a renameat2 Gnulib module, which mimicks the future glibc renameat2, but that can wait as nobody seems to need such a module now. * NEWS: Mention this. * lib/renameatu.c: Rename from lib/renameat2.c. * lib/renameatu.h: Rename from lib/renameat2.h. * modules/renameatu: Rename from modules/renameat2. * modules/renameatu-tests: Rename from modules/renameat2-tests. All uses of "renameat2" in identifiers or file name changed to "renameatu", except for two instances in lib/renameatu.c that deal with the Linux kernel's renameat2 syscall. 2018-07-04 Paul Eggert gnulib-tool: minor tweaks for --gnu-make * gnulib-tool: Do not allow --gnu-make in test modes, since they all require automake. (func_emit_lib_Makefile_am): Don’t emit automake comment if --gnu-make. regex: work around conditional-dependencies glitch * modules/regex (Depends-on): Add langinfo. Without this change, I had problems building an experimental version of GNU Emacs. The symptom of the bug was a message ‘./configure: line 12726: test: =: unary operator expected’. This was due to a line in gl_FUNC_NL_LANGINFO that invokes ‘test $HAVE_LANGINFO_CODESET = 1’ even though HAVE_LANGINFO_CODESET was unset. Although gl_FUNC_NL_LANGINFO has ‘AC_REQUIRE([gl_LANGINFO_H])’ and gl_LANGINFO_H always sets HAVE_LANGINFO_CODESET to 0 or 1, gnulib-tool with --conditional-dependencies sometimes arranges for the gl_FUNC_NL_LANGINFO code to be executed before the gl_LANGINFO_H code. Since the regex code includes it should be depending on the langinfo module anyway, and this happens to work around the bug, so install that as a workaround for now. To reproduce the original problem, run the following shell script on the version of Gnulib just before this patch was installed. rm -fr foo mkdir foo cat >foo/configure.ac <<'EOF' AC_INIT(GNU Emacs, 27.0.50, bug-gnu-emacs@gnu.org, , https://www.gnu.org/software/emacs/) gl_EARLY gl_INIT AC_OUTPUT EOF ./gnulib-tool --import --conditional-dependencies --gnu-make --dir foo regex ./gnulib-tool --copy build-aux/install-sh foo/install-sh ./gnulib-tool --copy build-aux/config.sub foo/config.sub ./gnulib-tool --copy build-aux/config.guess foo/config.guess cd foo aclocal -I m4 autoconf ./configure --with-included-regex 2018-07-01 Paul Eggert wchar: fix bug when checking for ‘inline’ I discovered this when looking into using the regex module with Emacs. * m4/wchar_h.m4 (gl_WCHAR_H_INLINE_OK): Fix bug introduced in 2016-08-17T23:09:38Z!skunk@iSKUNK.ORG; the code compiled conftest1.c and conftest2.c but these files were not created. As far as I can see, this check never worked and nobody reported it until now, which is a bit worrisome. 2018-06-30 Jim Meyering bootstrap: s/--option val/--option=val/ * build-aux/bootstrap (gnulib_tool_options): Change the spelling of "--option val" pairs to "--option=val", for aesthetics, and also so that this file no longer triggers a common help2man syntax-check warning when copied into projects like grep, gzip, etc. 2018-07-01 Paul Eggert manywarnings: omit -Wswitch-default This should make things more consistent, as we already ignore -Wswitch-enum. Problem reported by Reuben Thomas; see: https://lists.gnu.org/r/bug-gnulib/2018-05/msg00179.html * build-aux/g++-warning.spec, build-aux/gcc-warning.spec: Add -Wswitch-default. * m4/manywarnings-c++.m4 (gl_MANYWARN_ALL_GCC_CXX_IMPL): * m4/manywarnings.m4 (gl_MANYWARN_ALL_GCC): Remove -Wswitch-default. regex: revert most trimming Problems reported by Bruno Haible in: https://lists.gnu.org/r/bug-gnulib/2018-07/msg00001.html * modules/regex (Depends-on): Add lock, memcmp, memmove, and wctype back in. lock because regex users shouldn’t need to know that regex needs locking, and the rest because gnulib-tool should ordinarily ignore them anyway. 2018-06-30 Paul Eggert regex: trim module dependencies * modules/regex (Depends-on): Remove gettext-h and lock, since the regex code should work OK without these modules, and Emacs uses it that way. Also remove memcmp, memmove, and wctype, as these modules are obsolete and should not be needed any more. 2018-06-29 Paul Eggert regex: glibc does not use intprops.h Maybe we can talk glibc into using intprops.h someday, but now doesn’t seem to be a good time. * lib/regcomp.c (TYPE_SIGNED): Remove; regex_internal.h now defines. * lib/regex_internal.h [_LIBC]: Do not include intprops.h. (TYPE_SIGNED, INT_ADD_WRAPV): New macros. 2018-06-28 Paul Eggert regex: port to recently proposed glibc regex merge This patch is inspired by Adhemerval Zanella's recent proposal https://www.sourceware.org/ml/libc-alpha/2018-06/msg00905.html to merge glibc and Gnulib regex. It aims to simplify the merge on the glibc side, without keeping Gnulib portable. * lib/regex.h: Fix a problem with glibc installed-header checking, as follows: (_Restrict_): Prefer __restrict if defined or if GCC 2.95 or later. (_Restrict_arr_): Prefer __restrict_arr if defined, otherwise prefer _Restrict_ if C99 or GCC 3.1 or later (but not C++). * lib/regex_internal.c (re_string_realloc_buffers, build_wcs_buffer) (build_wcs_upper_buffer, build_upper_buffer) (re_string_translate_buffer, re_string_context_at): Move decls here from lib/regex_internal.h, for glibc internal tests. (build_wcs_upper_buffer): Use __wcrtomb, not wcrtomb, fixing glibc BZ #18496. * lib/regex_internal.h (lock_fini) [_LIBC]: Cast to 0 to pacify -Wunused-value. (bitset_set, bitset_clear, bitset_contain, bitset_empty) (bitset_set_all, bitset_copy, bitset_not, bitset_merge) (bitset_mask): Now static inline, and without any __attribute__ ((unused)) decoration, for glibc internal tests. 2018-06-25 Bruno Haible threadlib: Fix LIBMULTITHREAD on platforms where --as-needed is enabled. Reported by Erik Auerswald in . * m4/threadlib.m4 (gl_THREADLIB_BODY): Check whether the linker supports --as-needed/--no-as-needed and --push-state/--pop-state. When defining USE_POSIX_THREADS_WEAK or USE_SOLARIS_THREADS_WEAK or USE_PTH_THREADS_WEAK, define LIBMULTITHREAD in such a way that -lpthread / -lthread / -lpth does not get optimized away by a preceding --as-needed option. 2018-06-25 Bruno Haible Continue to use spaces for indentation, not tabs. * MODULES.html.sh: Untabify. * doc/regex.texi: Likewise. * lib/acl-internal.c: Likewise. * lib/dfa.c: Likewise. * lib/exclude.c: Likewise. * lib/exclude.h: Likewise. * lib/get-permissions.c: Likewise. * lib/gettimeofday.c: Likewise. * lib/parse-datetime.y: Likewise. * lib/pselect.c: Likewise. * lib/set-permissions.c: Likewise. * lib/time.in.h: Likewise. * m4/canonicalize.m4: Likewise. * m4/gc.m4: Likewise. * m4/gnulib-common.m4: Likewise. * m4/pthread_sigmask.m4: Likewise. * m4/vararrays.m4: Likewise. * tests/test-digest.h: Likewise. * tests/test-fcntl-h.c: Likewise. * tests/test-timespec.c: Likewise. * tests/uniwbrk/test-uc-wordbreaks.c: Likewise. 2018-06-25 Bruno Haible manywarnings: Don't enable -Wjump-misses-init warnings by default. * build-aux/gcc-warning.spec: Add -Wjump-misses-init. * m4/manywarnings.m4 (gl_MANYWARN_ALL_GCC(C)): Remove -Wjump-misses-init. 2018-06-25 Jim Meyering acl-internal.h: remove _GL_ATTRIBUTE_CONST on void function * lib/acl-internal.h (free_permission_context): Remove that attribute directive. Otherwise, it would provoke this from GCC 9: lib/acl-internal.h:300:3: error: 'const' attribute on function \ returning 'void' [-Werror=attributes] 2018-06-24 Jim Meyering parse-datetime: accommodate gcc-4.8.5 Bruno Haible reported the build failure in https://lists.gnu.org/r/bug-gnulib/2018-06/msg00066.html * lib/parse-datetime.y (parse_datetime2): Remove leading "static" on declaration of new local. 2018-06-24 Bruno Haible af_alg: Fail in continuable manner on Linux/powerpc64le. Reported by Assaf Gordon in . * lib/af_alg.c (afalg_stream): On non-seekable streams, try a single- byte send() as the first round. 2018-06-24 Bruno Haible af_alg: Fix state of stream after sendfile() succeeds. * lib/af_alg.c (afalg_stream): Invoke fflush and lseek, to ensure that the stream is correctly positioned afterwards. * modules/crypto/af_alg (Depends-on): Add fflush. * tests/test-digest.h (test_digest_on_files): Verify that after the operation the stream is positioned at end of file. 2018-06-24 Jim Meyering canon-host: take GCC9's advice rather than ignoring warning Pádraig Brady suggested not to ignore this GCC9 advice. * lib/canon-host.c: Undo preceding change. * lib/canon-host.h: Instead, declare with _GL_ATTRIBUTE_MALLOC. parse-datetime.y: avoid spurious GCC 9 warning * lib/parse-datetime.y (parse_datetime2): Save RELATIVE_TIME_0 into a function local prior to the first "goto fail".

Otherwise, building coreutils, I would see this: cc1: error: deprecated command line option '-Wchkp' [-Werror] cc1: error: -Wabi won't warn about anything [-Werror=abi] cc1: note: -Wabi warns about differences from the most up-to-date ABI,\ which is also used by default cc1: note: use e.g. -Wabi=11 to warn about changes from GCC 7 2018-06-24 Bruno Haible af_alg tests: Add another test. * tests/test-digest.h (test_digest_on_files): Also check a large file with a skipped header. * tests/test-md5.c: Include macros.h. * tests/test-sha1.c: Likewise. * tests/test-sha256.c: Likewise. * tests/test-sha512.c: Likewise. * modules/crypto/md5-tests (Files): Add tests/macros.h. * modules/crypto/sha1-tests (Files): Likewise. * modules/crypto/sha256-tests (Files): Likewise. * modules/crypto/sha512-tests (Files): Likewise. 2018-06-24 Pádraig Brady maint: clarify comments about sticky EOF * lib/af_alg.c: Be more direct that we can't assume stickiness of EOF for portability reasons. * lib/md5.c: Clarify that this isn't just a glibc issue. * lib/sha1.c: Likewise. * lib/sha256.c: Likewise. * lib/sha512.c: Likewise. 2018-06-24 Bruno Haible af_alg: Comment and style improvements. * lib/af_alg.c (alg_socket): Use 'size_t' as index into a string.

Further considerations why this should not be the default, at: https://lists.gnu.org/r/coreutils/2018-06/msg00034.html * m4/af_alg.m4: Require --with-linux-crypto to enable. * m4/gl-openssl.m4: Tweak accordingly. 2018-06-24 Pádraig Brady af_alg: avoid hangs when reading from streams * lib/af_alg.c (afalg_stream): Don't assume EOF is sticky, and thus avoid doing a fread() when feof() is set. * lib/md5.c: Ensure feof() is called before fread(). * lib/sha1.c: Likewise. * lib/sha256.c: Likewise. * lib/sha512.c: Likewise. 2018-06-24 Pádraig Brady af_alg: fix error handling when hash not returned * lib/af_alg.c (afalg_stream): Handle the case where we've successfully written data to the kernel in the read/write loop, but the kernel doesn't respond with the hash. 2018-06-24 Paul Eggert libc-config: merge from glibc * lib/cdefs.h (__inline, __restrict): Copy from current glibc. This fixes glibc bug 17721, which Gnulib had already fixed in a different way. (__nonnull): Lessen the distance from glibc by using the glibc definition inside an ‘#ifndef __nonnull’. (__attribute_nonstring__): New macro, copied from current glibc. * lib/libc-config.h (__attribute_nonstring__): New undef. (__restrict): Remove; workaround no longer needed. Keep the __inline workaround, though, as it uses HAVE___INLINE to support more compilers than the glibc __inline can. 2018-06-24 Bruno Haible mbrtowc, wcwidth: Fix MT-safety bug (regression from 2018-06-23). * lib/mbrtowc.c (enc_t): New enum type.

Include libc-lock.h if _LIBC, and define substitute macros otherwise. (unsafe_state): Rename from generator. All uses changed. Use C99-style initializers. (__random, __srandom, __initstate, __setstate): Rename from non-underscored version, but define it to non-underscored version on Gnulib. Add a lock. * lib/random_r.c (__srandom_r, __initstate_r, __setstate_r, __random_r): Likewise. Do not include ; not needed since stdlib.h defines int32_t. (weak_alias, __set_errno) [!_LIBC]: Remove; now done by libc-config. (__srandom_r): Use int32_t instead of long int where int32_t will do. (__random_r): Use uint32 to fix glibc bug 17343. * modules/random, modules/random_r (Depends-on): Add libc-config. Depend on stdint only if $HAVE_RANDOM = 0. 2018-06-19 Jim Meyering README-release: also run any check-very-expensive tests * top/README-release: Adjust instructions so they run the check-very-expensive tests when there is such a target. 2018-06-18 Bruno Haible pthread_rwlock_rdlock: Add comments regarding glibc behaviour. * m4/pthread_rwlock_rdlock.m4: Add comment. * doc/posix-functions/pthread_rwlock_rdlock.texi: Mention that rwlocks are reader-preferring in glibc. * doc/posix-functions/pthread_rwlock_tryrdlock.texi: Likwise. * doc/posix-functions/pthread_rwlock_timedrdlock.texi: Likewise. 2018-06-17 Paul Eggert crypto: use byteswap * lib/md4.c, lib/md5.c, lib/sha1.c, lib/sha256.c, lib/sha512.c: * lib/sm3.c: Include .

Emacs needs this, as it does not use the stream operations and doesn’t need all the af_alg stuff we’ve recently added. Perhaps a similar change is needed to the other crypto modules, but this patch changes only those needed for Emacs. * modules/crypto/md5-buffer, modules/crypto/sha1-buffer: * modules/crypto/sha256-buffer, modules/crypto/sha512-buffer: New modules, used by Emacs. * modules/crypto/md5, modules/crypto/sha1, modules/crypto/sha256: * modules/crypto/sha512: Rewrite to depend on the new modules. 2018-05-20 Pádraig Brady fts: avoid a memory leak edge case * lib/fts.c (fts_open): Set an appropriate fts_level so that an immediate fts_close() will free the allocation. * tests/test-fts.c (fts_dealloc): Add a test case which will trigger under valgrind or address sanitizer.

It’d be better to fix localtime and localtime_r instead, but that would be more work and is not needed to fix the Emacs problem. * m4/time_rz.m4 (gl_TIME_RZ): Detect the bug. 2018-03-24 Jim Meyering test-version-etc.sh: don't use diff directly: use init.sh's compare We'd rather not sacrifice readable "diff -u" output even for "diff -c" output (not supported by busybox) or for even less readable ed-style "diff" output. So use init.sh's compare function * tests/test-version-etc.sh: Source init.sh and add "." to path. Remove "./" from invocation of test-version-etc, so we use path. And s/diff/compare/. * modules/version-etc-tests (Depends-on): Add test-framework-sh, to get init.sh.

Problem reported by Pádraig Brady in: https://lists.gnu.org/r/bug-gnulib/2017-11/msg00048.html * NEWS: Mention this. * lib/posixtm.c (posix_time_parse): Treat the absence of PDS_TRAILING_YEAR as if PDS_LEADING_YEAR were present. * lib/posixtm.h (PDS_LEADING_YEAR): Remove (actually, leave it present, but define it as zero, for compatibility with existing source code). All other PDS_* values moved up. * tests/test-posixtm.c (LY): New macro. (T): Use it.

Treat "guessing yes" like "yes". 2017-11-11 Paul Eggert faccessat: port to macOS (Bug#29231) macOS faccessat has the same bug that lstat does: if the file name ends in '/' it ignores the trailing slash. Problem reported for Emacs by Vincent Zhang. * doc/posix-functions/faccessat.texi (faccessat): Document this. * lib/faccessat.c (_GL_INCLUDING_UNISTD_H): Define and undef around the initial includes. Include errno.h, string.h, sys/stat.h. (orig_faccessat) [HAVE_FACCESSAT]: New function. Include "unistd.h" after defining it. (rpl_faccessat) [HAVE_FACCESSAT]: New implementation. * lib/unistd.in.h (faccessat) [REPLACE_FACCESSAT]: Handle in the usual way. * m4/faccessat.m4 (gl_FUNC_FACCESSAT): Replace faccessat if lstat dereferences symlinks, since faccessat is likely to have the same problem. * m4/unistd_h.m4 (gl_UNISTD_H_DEFAULTS): Default REPLACE_ACCESSAT. * modules/faccessat (Depends-on): Add fstatat. Depend if REPLACE_FACCESSAT is 1, too.

Check on all systems, not just MinGW. Use a heuristic involving TIME_T_32_BIT_OK, cross_compiling, and the touch command to output a failure or just a warning, to make it more likely that builders will select 64-bit time_t. 2017-11-05 Paul Eggert havelib: fix typo in previous change * m4/lib-prefix.m4 (AC_LIB_PREPARE_MULTILIB): Fix typo. Don’t use AC_EGREP_CPP if affected by CFLAGS * m4/float_h.m4 (gl_FLOAT_H): * m4/host-cpu-c-abi.m4 (gl_HOST_CPU_C_ABI): * m4/lib-ld.m4 (AC_LIB_PROG_LD): * m4/lib-prefix.m4 (AC_LIB_PREPARE_MULTILIB): * m4/year2038.m4 (gl_YEAR2038): Prefer AC_COMPILE_IFELSE to AC_EGREP_CPP when testing conditions likely to be affected by the choice of CFLAGS, since CFLAGS are not used by AC_EGREP_CPP. Without this patch, ‘./configure CFLAGS="-m32"’ fails on gzip with GNU/Linux x86-64. fstatat: pacify GCC on unusual platform * lib/fstatat.c (orig_fstatat) [!HAVE_WORKING_FSTATAT_ZERO_FLAG]: Omit, as it’s unused in this case. 2017-10-29 Paul Eggert timespec: prefer ‘assume’ to ‘assure’ This avoids some runtime tests. The rest of the module makes similar assumptions and there is little point to testing here. * lib/timespec.h: Include verify.h instead of assure.h. (timespec_cmp): Use ‘assume’, not ‘assure’.

(main): Test dangling symlinks, if symlinks are supported. glob, backupfile: inode 0 is a valid inode number * doc/posix-functions/readdir.texi (readdir): * doc/posix-headers/dirent.texi (dirent.h): Document more readdir portability issues. * lib/backupfile.c (REAL_DIR_ENTRY): Remove. (numbered_backup): Don’t treat inode 0 any differently from other inode values. * lib/glob.c (struct readdir_result): Remove skip_entry member. (readdir_result_skip_entry, D_INO_TO_RESULT): Remove. All uses removed. * modules/glob (Depends-on): Remove d-ino. glob: simplify symlink detection * lib/glob.c (dirent_type): New type. Use uint_fast8_t not uint8_t, as C99 does not require uint8_t. (struct readdir_result): Use it. Do not define skip_entry unless it is needed; this saves a byte on platforms lacking d_ino. (readdir_result_type, readdir_result_skip_entry): New functions, replacing ... (readdir_result_might_be_symlink, readdir_result_might_be_dir): ... these functions, which were removed. This makes the callers easier to read. All callers changed. (D_INO_TO_RESULT): Now empty if there is no d_ino. 2017-08-30 Pádraig Brady fts-tests: tag as a longrunning-test so not included by default * modules/fts-tests: This test takes about 20s on current systems, and uses about 285M of space on ext4. 2017-08-30 Pádraig Brady renameat2: fix compilation on alpine linux * m4/renameat.m4: Check for presence. * lib/renameat2.h: Only include if present. Reported by Assaf Gordon on Alpine Linux. 2017-08-24 Paul Eggert glob: try to port recent changes to MS-Windows Problem reported by Bruno Haible in: http://lists.gnu.org/r/bug-gnulib/2017-08/msg00170.html * lib/glob.c (__glob_pattern_p) [!_LIBC]: Move from here ... * lib/glob.in.h (__glob_pattern_p): ... to here. 2017-08-24 Eric Blake warnings: fix compilation with old autoconf * m4/warnings.m4 (gl_UNKNOWN_WARNINGS_ARE_ERRORS(C)) (gl_UNKNOWN_WARNINGS_ARE_ERRORS(C++)): Use m4_defun rather than AC_DEFUN. * m4/manywarnings.m4 (gl_MANYWARN_ALL_GCC(C)) (gl_MANYWARN_ALL_GCC(C++)): Likewise. 2017-08-24 Bruno Haible glob: Fix compilation error on NetBSD 7.0 and OpenBSD 6.0. * modules/glob (Depends-on): Add c99. 2017-08-24 Paul Eggert glob: fix typo that broke platforms lacking d_ino This typo also hurt performance on GNU/Linux and similar hosts. * lib/glob.c (D_INO_TO_RESULT): Fix typo (reversed ifdef) in previous change. 2017-08-23 Paul Eggert glob: merge from glibc with Zanella glob changes Merge glob from glibc, with changes for glob proposed by Adhemerval Zanella in the thread starting here: https://sourceware.org/ml/libc-alpha/2017-08/msg01079.html plus some fixes for this merge. * lib/glob_internal.h, lib/glob_pattern_p.c, lib/globfree.c: New files, ported from glibc. * lib/glob-libc.h (_Restrict_): Remove. All uses replaced with __restrict. (__size_t): Remove. All uses replaced by size_t. (size_t): Define by defining __need_size_t and including . This should work even in non-glibc platforms, where any name pollution is OK. Use __USE_MISC instead of __USE_BSD || __USE_GNU. (struct stat64): Don’t worry about __GLOB_GNULIB. (glob, globfree, glob_pattern_p): Remove macros for __USE_FILE_OFFSET64 && __GNUC__ < 2 && !defined __GLOB_GNULIB case. Remove _GL_ARG_NONNULL as GNU behavior is to accept NULL but set errno. * lib/glob.c (_GL_ARG_NONNULL) [!_LIBC]: Remove. All uses removed since the glibc behavior works on null pointers. Do not include stdio.h; old SunOS is irrelevant now. Do not worry about GLOB_ONLY_P as we now mimic glibc here. Include glob_internal.h. (D_INO_TO_RESULT): Depend on (_LIBC || D_INO_IN_DIRENT), not ((POSIX || WINDOWS32) && !__GNU_LIBRARY__). The latter probably worked only coincidentally. (attribute_hidden, __attribute_noinline__, __glibc_unlikely): Remove macros; now done in glob.in.h. (size_add_wrapv): Do not use __builtin_add_overflow if __ICC. (glob): Properly initialize glob structure with GLOB_BRACE|GLOB_DOOFFS (bug 20707). Remove old code using SHELL since Bash no longer uses this. (glob, prefix_array): Separate MS code better. (glob, glob_in_dir): Use C99 decls before statements when glibc does. (glob_in_dir): Remove old Amiga and VMS code. (globfree, __glob_pattern_type, __glob_pattern_p): Move to separate files. * lib/glob.in.h (attribute_hidden, __attribute_noinline__) (__glibc_unlikely): Move here from glob.c.

(glob_in_dir): Do not rely on undefined behavior in accessing struct members beyond their bounds. Use a flexible array member instead. 2017-08-21 Paul Eggert vc-list-files: port to Solaris 10 * build-aux/vc-list-files: Don't assume test -e works. 2017-08-21 Karl Berry * doc/posix-functions/srandom.texi (srandom): typo }. 2017-08-20 Paul Eggert git-version-gen: port to Solaris 10 Problem reported by Dagobert Michelsen in: http://lists.gnu.org/r/grep-devel/2017-08/msg00002.html * build-aux/git-version-gen (v_from_git): Use expr instead of shell substitution. 2017-08-19 Bruno Haible host-cpu-c-abi: Improve detection of MIPS ABI. * m4/host-cpu-c-abi.m4 (gl_HOST_CPU_C_ABI): For MIPS, test the value of _MIPS_SIM. 2017-08-17 Bruno Haible hypot tests: Fix test failure on FreeBSD 11.0/x86. * tests/test-hypot.h (test_function): Declare z as 'volatile'. 2017-08-17 Bruno Haible float: Fix LDBL_MIN value on FreeBSD/x86. * lib/float.in.h (LDBL_MIN) [__FreeBSD__]: Add more precision. 2017-08-17 Bruno Haible random: Fix test compilation failure on Cygwin 1.5.25. * m4/stdlib_h.m4 (gl_STDLIB_H_DEFAULTS): Initialize HAVE_DECL_INITSTATE, HAVE_DECL_SETSTATE. * m4/random.m4 (gl_FUNC_RANDOM): Test whether initstate and setstate are declared. * modules/stdlib (Makefile.am): Substitute HAVE_DECL_INITSTATE, HAVE_DECL_SETSTATE. * lib/stdlib.in.h (initstate): Declare also if HAVE_DECL_INITSTATE is 0.

Suggested by Markus Armbruster in: http://lists.gnu.org/r/bug-gnulib/2017-08/msg00034.html 2017-08-06 Bruno Haible warnings, manywarnings: Add support for multiple languages, not just C. * warnings.m4 (gl_UNKNOWN_WARNINGS_ARE_ERRORS_IMPL): Renamed from gl_UNKNOWN_WARNINGS_ARE_ERRORS. (gl_UNKNOWN_WARNINGS_ARE_ERRORS(C)): New macro. (gl_UNKNOWN_WARNINGS_ARE_ERRORS(C++)): New macro. (gl_UNKNOWN_WARNINGS_ARE_ERRORS): Dispatch to gl_UNKNOWN_WARNINGS_ARE_ERRORS(_AC_LANG). (gl_WARN_ADD): Require the gl_UNKNOWN_WARNINGS_ARE_ERRORS specialization of the current language. If C++ is the current language, modify WARN_CXXFLAGS instead of WARN_CFLAGS. * manywarnings.m4 (gl_MANYWARN_ALL_GCC(C)): New macro, extracted from gl_MANYWARN_ALL_GCC. (gl_MANYWARN_ALL_GCC): Dispatch to gl_MANYWARN_ALL_GCC(_AC_LANG). 2017-08-06 Markus Armbruster git-version-gen: Fix for tags containing '-' Really old versions of git-describe (before v1.5.0, Feb 2007) don't have the number of commits in their long format output, i.e. where modern 'git describe --abbrev=4 --match="v*"' prints "v0.1-1494-g124b9", they print "v0.1-1494-g124b9". git-version-gen recognizes both patterns, and normalizes the old format to the new one. Unfortunately, this normalization code gets confused when the tag contains '-'. Reproducer: $ git-tag -m test v0.2-rc1 $ build-aux/git-version-gen .tarball-version; echo build-aux/git-version-gen: WARNING: git rev-list failed UNKNOWN We take exact tag "v0.2-rc1" for the old format, extract the presumed tag "v0.2" from it, then run "git rev-list v0.2..HEAD" to count commits since tha tag. Fails, because tag "v0.2" does not exist. * git-version-gen: We could perhaps drop support for versions from more than a decade ago. But tightening the pattern match is easy enough, so do that. Still breaks when you use version tags ending in something matching -g????, but you arguably get what you deserve then. 2017-08-05 Paul Eggert valgrind-tests: use ls, and cache * m4/valgrind-tests.m4: Test ls, not bash. Problem reported by Reuben Thomas. Also, cache the result so that it can be overridden. 2017-08-04 Paul Eggert manywarnings: port to 64-bit GCC builds of Emacs * m4/manywarnings.m4 (gl_MANYWARN_ALL_GCC): Compute max safe object size rather than hardwiring 2147483647. This is needed to build GNU Emacs, which has one conditional (and used only-in-theory) call to malloc with a literal greater than 2147483647. 2017-08-04 Bruno Haible Relax the license of some modules with no runtime code. * modules/std-gnu11 (License): Set to 'unlimited'. * modules/c99 (License): Likewise.

Don't interpret EOVERFLOW to mean nonexistence * lib/fts.c (fts_stat): If lstat fails, report its errno, which may be EOVERFLOW; this is likely more useful than reporting the stat errno. * lib/glob.c (link_stat): Rename from link_exists2_p and return -1/0 instead of 0/1. Caller changed. * lib/glob.c (link_exists_p): * lib/renameat2.c (rename_noreplace, renameat2): * lib/tempname.c (try_nocreate): If errno == EOVERFLOW then the directory entry exists, so do not act as if it does not exist. backup-rename: new module It is like backupfile, except it avoids some race conditions, and it does not output to stderr or exit. * MODULES.html.sh: Add backup-rename. * lib/backup-find.c, lib/backup-internal.h, lib/backup-rename.c: * modules/backup-rename: New files. * lib/backupfile.c: Turn this into an internals file, which contains code common to backupfile and backup_rename. Include backupfile-internal.h instead of backupfile.h. Do not include argmatch.h or xalloc.h: include xalloc-oversized.h. Include renameat2.h and fcntl.h. (BACKUP_NOMEM): New constant. (numbered_backup): New args BASE_OFFSET and *DIRPP. Do not exit on memory exhaustion; just return BACKUP_NOMEM. Caller changed. (backupfile_internal): Rename from find_backup_file_name. Support new arg RENAME.

Add goto to use a label, to silence picky compilers. fts-tests: port to gcc -Wwrite-strings * tests/test-fts.c (base, base_d): New static vars. (argv, remove_tree, main): Use them. 2017-07-26 Reuben Thomas relocatable-lib{,-lgpl}: improve documentation * doc/relocatable-maint.texi: Document use of relocatable-lib{,-lgpl}.

They can still be used under the LGPL, using the --lgpl option to gnulib-tool. 2017-07-30 Bruno Haible host-cpu-c-abi: Detect ILP32 ABI on IA-64 HP-UX. * m4/host-cpu-c-abi.m4 (gl_HOST_CPU_C_ABI): Distinguish ia64-ilp32 from ia64. For arm64, test only __aarch64__, as __ARM_64BIT_STATE and __ARM_PCS_AAPCS64 are not reliable indicators: they are not defined on Ubuntu 14.04 (gcc 4.8.4) and Debian 8 (gcc 4.9.2). 2017-07-27 Paul Eggert faccessat: document AT_SYMLINK_NOFOLLOW issue * doc/posix-functions/faccessat.texi: Modernize platform list. Document AT_SYMLINK_NOFOLLOW limitation. renameat2: port to Solaris 10 * lib/renameat2.c (rename_noreplace): Use lstat, not faccessat with AT_SYMLINK_NOFOLLOW (which is not portable). (renameat): Undef before using, to avoid endless recursion when the replacement renameat calls renameat2 which calls the replacement renameat. (renameat2): Use lstatat, not faccessat with AT_SYMLINK_NOFOLLOW. * modules/renameat2 (Depends-on): Remove faccessat. * modules/renameat-tests (test_renameat_LDADD): * modules/renameat2-tests (test_renameat2_LDADD): Remove $(LIB_EACCESS). renameat2: new module Although the Linux syscall renameat2 is not in glibc (yet?), it is useful to have access to its RENAME_NOREPLACE flag. * MODULES.html.sh (func_all_modules): Add renameat2. * lib/renameat2.c, lib/renameat2.h, modules/renameat2: * modules/renameat2-tests, tests/test-renameat2.c: New files. * lib/renameat.c (renameat): Move most of the implementation to renameat2, and just call renameat2. * modules/renameat (Files): Remove lib/at-func2.c. (Depends-on): Depend only on renameat2. (Include): Remove . * modules/renameat-tests (test_renameat_LDADD): Add $(LIB_EACCESS), since renameat (via renameat2) might use faccessat. 2017-07-27 Erik Skultety (tiny change) vc-list-files: Adjust the script to support git worktrees * build-aux/vc-list-files: Require existence, not directory. 2017-07-26 Paul Eggert doc: bring MODULES.html.sh up to date Somehow a few months ago we stopped updating MODULES.html.sh.

Reported by Gisle Vanem in . 2017-04-22 Paul Eggert parse-datetime: overflow and debug cleanups This long patch was triggered by this bug report from Ruediger Meier: http://lists.gnu.org/r/bug-gnulib/2017-04/msg00028.html I fixed the bug he noted, then found some others nearby, and then still others. Oh my goodness, there were a lot of bugs. I cleaned up some of the code to follow GNU standards while I was at it. * lib/parse-datetime.y (ISDIGIT): Remove; all callers changed to use c_isdigit. (EPOCH_YEAR): Remove; unused. (TM_YEAR_BASE): Now an enum rather than a macro. (HOUR, debug_strfdatetime): Multiply hour by 3600, not 60, to get time zone offset, since timezones now are in terms of seconds and not minutes. (long_time_t): Remove. All uses replaced by time_t or intmax_t as appropriate. Verify that intmax_t is wide enough. (time_overflow, time_zone_str): New functions, used to deal more reliably with overflow. (dbg_printf): Add printf attribute, to help catch integer width errors. (textint, relative_time, parser_control, time_zone_hhmm, set_hhmmss) (%union, to_hour, yylex, parse_datetime2): Use intmax_t instead of long int and/or long_time_t. All uses changed. (DBGBUFSIZE): Move earlier. (relative_time, set_hhmmss, parser_control): Just use int for nanoseconds and for time zones; that’s wide enough. (parser_control): Use bool for members like year_seen that can be booleans instead of counters. All uses changed. Remove debug_default_input_timezone; no longer needed. All uses removed. (apply_relative_time): Return a bool overflow flag. All uses changed to check for overflow. (apply_relative_time, zone, date, relunit, relunit_snumber) (signed_seconds, unsigned_seconds, yylex, parse_datetime2): Check for integer overflow portably. (str_days): Use just int for N, as it’s wide enough. Prefer 2D char arrays to arrays of char * when it looks like 2D is a win on typical platforms. Prefer snprintf to strncpy/strncat, for simplicity; all buffers are smaller than INT_MAX so this is safe. (TIME_ZONE_BUFSiZE, TM_YEAR_BUFSIZE): New constants. (debug_print_current_time): Don’t assume tv_nsec is of type long, as this is not true on x32. Output "." before any nanoseconds.

(PRINT_REL_PART): ... this macro, which was removed. All uses changed. (debug_print_relative_time): Use bool for boolean. (local_zone): dsts_seen now counts only tDST instances. (date): Fix printf of size_t to use %z. Do not assume numeric tokens have negative values merely because the context suggests a syntax with "-" separating tokens. (time_zone_hhmm): Return bool success indicator, which checks for overflow. Store result into PC->time_zone instead. All callers changed. (tm_year_str): New function. Return a bool success indicator and store the result into a buffer. All callers changed. Output the numerically correct string even if adding 1900 to the year would overflow. (to_tm_year): New function, replacing the old to_year. All callers changed. (tm_diff): Sync with glibc. (lookup_word): Use to_uchar instead of doing it by hand. (TZBUFSIZE): Now local to the only function that needs it. (debug_strfdatetime): Simplify now that time zones are int seconds. (debug_strfdate): Work even if tm_year + 1900 would overflow. (get_effective_timezone): Remove. All uses removed. (parse_datetime2): Use fprintf in pieces instead of snprintfing to a fixed-size buffer. Don’t assume that gmtime succeeds iff localtime succeeds. Use tm_gmtoff if available. Simplify how ‘goto fail;’ works in conjunction with the ‘ok’ flag. * m4/parse-datetime.m4 (gl_PARSE_DATETIME): Don’t define TIME_T_FITS_IN_LONG_INT, as it is no longer needed. * modules/parse-datetime (Depends-on): Add inttypes. 2017-04-21 Bruno Haible gettext-h: Avoid -Wundef warning. * lib/gettext.h: Test the value of ENABLE_NLS only if it is defined.

For the record, if we ever run into a pedantic compiler that behaves differently from GCC when converting an out-of-range value to a signed integer, we can work around the problem with something like the following code, where UCT is the signed counterpart of T (UCT is sometimes narrower than UT) and all callers are changed accordingly: #if __SUNPRO_C <= 0x5120 # define _GL_INT_OP_WRAPV_VIA_UNSIGNED(a, b, op, uct, ut, t) \ ((t) ((ut) (a) op (ut) (b))) #else # define _GL_INT_OP_WRAPV_VIA_UNSIGNED(a, b, op, uct, ut, t) \ (TYPE_MINIMUM (t) <= (uct) ((ut) (a) op (ut) (b)) \ ? ((t) (uct) (((ut) (a) op (ut) (b)) - TYPE_MINIMUM (t)) \ + TYPE_MINIMUM (t)) \ : (t) (uct) ((ut) (a) op (ut) (b))) #endif 2017-04-14 Paul Eggert intprops: try to avoid tickling similar bugs * lib/intprops.h (_GL_INT_OP_CALC): Document that UT no longer needs to be the same width as T; it can be wider. Change callers so that UT is at least as wide as unsigned int, as I suspect that this is less likely to run into compiler bugs. intprops: port to Oracle Studio 12.3 x86 Problem reported by Gavin Smith in: http://lists.gnu.org/r/bug-gnulib/2017-04/msg00049.html * lib/intprops.h (_GL_INT_OP_WRAPV_VIA_UNSIGNED): Convert unsigned to signed via the usual rather than the standard way, to avoid a compiler bug in Oracle Studio 12.3 x86. 2017-04-08 Paul Eggert getopt: prefer - to _ in new file names * lib/getopt-cdefs.in.h: Rename from lib/getopt_cdefs.in.h. * lib/getopt-core.h: Rename from lib/getopt_core.h. * lib/getopt-ext.h: Rename from lib/getopt_ext.h. * lib/getopt-pfx-core.h: Rename from lib/getopt_pfx_core.h. * lib/getopt-pfx-ext.h: Rename from lib/getopt_pfx_ext.h. All uses changed. getopt: port recent getopt changes to macOS Problem reported by Harald Maier (Bug#26398). The macOS C compiler uses __nonnull for its own purposes and that clashes with glibc's __nonnull. * lib/getopt.in.h: Add comment for _GL_ARG_NONNULL snippet. * lib/getopt_cdefs.in.h (__nonnull): Remove. * lib/getopt_core.h (getopt): * lib/getopt_ext.h (getopt_long, getopt_long_only): Use _GL_ARG_NONNULL, not __nonnull. * lib/unistd.in.h: Move snippet hooks to before where the getopt .h files are included, so that _GL_ARG_NONNULL is defined in time. * modules/getopt-posix (Depends-on): Add snippet/arg-nonnull. (getopt.h): Interpolate _GL_ARG_NONNULL snippet. 2017-04-06 Paul Eggert getopt-gnu: omit some duplicate code * m4/getopt.m4 (gl_FUNC_GETOPT_GNU): Don’t require gl_FUNC_GETOPT_POSIX, as the configure.ac code generated by gnulib-tool already does this. * modules/getopt-gnu (configure.ac): Omit code duplicated from getopt-posix, which we depend on. getopt-posix: use angle-bracket include * lib/getopt1.c: Include , not "config.h". 2017-04-06 Zack Weinberg getopt: annotate files with relationship to glibc As the final act in this patchset, adjust the message at the top of each file to indicate which files are synced with glibc. (This has already been done for most of the headers.) * lib/getopt.c, lib/getopt1.c, lib/getopt_int.h: Mention in top-of-file boilerplate that these files are shared between glibc and gnulib. getopt: split up getopt.in.h and eliminate __need_getopt Over in glibc, all of the __need macros are being phased out in favor of small headers that declare only the necessary components, as this is much simpler and less prone to bugs. As getopt is shared with glibc, gnulib needs to do the same for __need_getopt. __need_getopt is misnamed; what it really means is "we want only the getopt features specified in POSIX, not the GNU extensions". glibc placed the "meat" of getopt.h into getopt_core.h and getopt_ext.h; these files can be shared verbatim with gnulib. The portability wrapper, on the other hand, they have renounced altogether; glibc's getopt.h will no longer be shared with gnulib at all. In exchange, certain glibc-specific quirks (having to do with __posix_getopt) no longer need appear in gnulib's headers at all. This patch merges getopt_core.h and getopt_ext.h from glibc, and splits up the current gnulib-side portability wrapper into three additional headers: getopt_pfx_core.h and getopt_pfx_ext.h handle __GETOPT_PREFIX for their respective headers, getopt_cdefs.in.h handles things like __BEGIN_DECLS and __THROW, and getopt.in.h and unistd.in.h just use them. All new files are clearly marked with whether they are shared with glibc. * lib/getopt.in.h: Eliminate __need_getopt. Break up into ... * lib/getopt_core.h, lib/getopt_ext.h: ... these new files shared with glibc, and ... * lib/getopt_cdefs.in.h, lib/getopt_pfx_core.h * lib/getopt_pfx_ext.h: ... these new files not shared with glibc. * lib/unistd.in.h: Include getopt_cdefs.h and getopt_pfx_core.h, instead of defining __need_getopt and including the full getopt.h. * m4/getopt.m4 (gl_GETOPT_SUBSTITUTE_HEADER): Check for sys/cdefs.h. Define substitution variables GETOPT_CDEFS_H and HAVE_SYS_CDEFS_H. * modules/getopt-posix (Files): Add new headers and sort list. (Depends-on): No longer need snippet/arg-nonnull. (Makefile.am): Generate getopt_cdefs.h. getopt: better handling of ambiguous options glibc's getopt uses alloca to construct a linked list of possibilities for an "ambiguous" long option. In gnulib, malloc should be used instead. Providing for both cases complicates things a fair bit. This patch rewrites ambiguous-option handling to use a boolean vector instead of a linked list. There is then only one allocation that might need freeing; in glibc it can honor __libc_use_alloca as usual, and in gnulib we define __libc_use_alloca to always be false, so we don't need ifdefs in the middle of the function. This should also be slightly more efficient in the normal case of long options being fully spelled out -- I think most people aren't even aware they _can_ sometimes abbreviate long options. One interesting consequence is that the list of possibilities is now printed in exactly the order they appear in the list of long options, instead of the first possibility being shuffled to the end. (The patch looks bigger than it really is because there's a fair bit of reindentation and code rearrangement.) * lib/getopt.c: When used standalone, define __libc_use_alloca as always false and alloca to abort if called. (process_long_option): Rewrite handling of ambiguous long options to use a single boolean vector, not a linked list; use __libc_use_alloca to decide whether to allocate this using alloca. getopt: refactor long-option handling There were two copies of the bulk of the code to handle long options. Now there is only one. This change temporarily removes the logic to avoid using alloca when standalone; the next patch in the series will restore it. * lib/getopt.c (process_long_option): New function split out from _getopt_internal_r. (_getopt_internal_r): Replace both copies of the long-option processing code with calls to process_long_option. getopt: tidy up _getopt_initialize a bit _getopt_data.__posixly_correct is completely redundant to _getopt_data.__ordering, and some work that logically belongs in _getopt_initialize was being done by _getopt_internal_r, making the code harder to understand. As a side effect, getenv will no longer be called if the first character of the options string is '+' or '-', which is probably a Good Thing. (Perhaps we should have a flag character that specifically asks for the permutation behavior?) * lib/getopt_int.h (_getopt_data): Remove __posixly_correct field. * lib/getopt.c (_getopt_internal_r): Move some initialization code... (_getopt_initialize): ...here. Don't set d->__posixly_correct. getopt: merge from glibc: repetition reduction The definitions of the entry point functions 'getopt' and '__posix_getopt' can be made substantially less repetitive with a helper macro. While I was merging the const-correctness changes from gnulib into glibc I noticed there are still some unnecessary casts in _getopt_internal_r. * lib/getopt.c (getopt, __posix_getopt): Eliminate repetition with a macro. Consistently cast 'argv' to 'char **' when calling _getopt_internal. (_getopt_internal_r): Remove unnecessary casts when calling exchange. getopt: clean up error reporting getopt can print a whole bunch of error messages, and when used standalone (from gnulib) it uses fprintf to do that. But fprintf is a cancellation point and getopt isn't, and also applying fprintf to a stream in wide-character mode is not allowed. So every single error reporting case has an #ifdef _LIBC block in which it calls internal libc functions instead. The counterpart patch series in glibc makes it possible to simplify all of that down to a set of #defines at the top of the file; core code is written as if it is safe to just call fprintf, flockfile, and funlockfile. (One caveat: it's *not* safe to call any *other* stdio functions.) * lib/getopt.c: When _LIBC is defined, define fprintf to __fxprintf_nocancel, flockfile to _IO_flockfile, and funlockfile to _IO_funlockfile. When neither _LIBC nor _POSIX_THREAD_SAFE_FUNCTIONS is defined, define flockfile and funlockfile as no-ops. (_getopt_internal_r): Remove all internal #ifdef _LIBC blocks; the standalone error-printing code can now be used for libc as well. Add an flockfile/funlockfile pair around one case where the error message is printed in several chunks. Don't use fputc. getopt: fix fencepost error in ambiguous-W-option handling getopt_long contains an undocumented (AFAICT) feature in which, if you put "W;" in the short-options list, then '-W foo' and '-Wfoo' are treated as equivalent to '--foo'. This is implemented with a partial second copy of the code for handling long options, and that code increments optind one too many times when recovering from an ambiguous abbreviated option, which can cause the main loop to walk past the end of argv and crash. I discovered this while writing a test case that tries to exercise all of getopt's error reporting paths; I wouldn't be surprised to learn that this feature is never used by real applications. * lib/getopt.c (_getopt_internal_r): Don't increment d->optind a second time when reporting ambiguous -W options. getopt: clean up getopt.c and getopt1.c file headers In getopt.c, there is no need to include wchar.h at all, and it is safe nowadays to assume that stdlib.h does declare getenv (several other gnulib modules make this assumption). In getopt1.c, the #ifdef _LIBC block at the top can be simplified by using "" inclusions consistently, and there is no actual need to include stdlib.h (except in the #ifdef TEST block, where it should be unconditional), nor to provide a backup definition of NULL at all. * lib/getopt1.c: Simplify #ifdeffage at top of file. Move inclusion of stdlib.h to #ifdef TEST block and make unconditional. Do not define NULL. * lib/getopt.c: Don't include wchar.h. No need to declare getenv. * m4/getopt.m4 (gl_PREREQ_GETENV): Delete. * modules/getopt-gnu, modules/getopt-posix: Don't call gl_PREREQ_GETENV. getopt: harmonize comments with glibc The comments explaining how the behavior of 'getopt' varies depending on whether it's the standalone version and whether there are special characters at the beginning of the options string were inconsistent between gnulib and glibc, and also out of sync with the code. * lib/getopt.c, lib/getopt_int.h: Harmonize comments with glibc. getopt: remove USE_NONOPTION_FLAGS getopt includes code to parse an environment variable named _XXX_GNU_nonoption_argv_flags_ (where XXX is the current process's PID in decimal); but all of it has been #ifdefed out since 2001, with no official way to turn it back on. According to commentary in glibc's config.h.in, bash version 2.0 set this environment variable to indicate argv elements that were the result of glob expansion and therefore should not be treated as options, but the feature was "disabled later" because "it caused problems". According to bash's CHANGES file, "later" was release 2.01; it gives no more detail about what the problems were. Version 2.0 of bash was released on the last day of 1996, and version 2.01 in June of 1997. Twenty years later, I think it is safe to assume that this environment variable isn't coming back. * lib/getopt_int.h: Remove all #ifdef USE_NONOPTION_FLAGS blocks. * lib/getopt.c: Likewise. Also remove SWAP_FLAGS and the __libc_argc and __libc_argv externs, which were only used by #ifdef USE_NONOPTION_FLAGS blocks. getopt: tabify, in preparation for merge with glibc glibc sticks to the GNU default of indenting with a mix of 8-column tabs and spaces; make the gnulib copy match. getopt.h is not included because it is *not* going to be merged in its present form. * getopt.c, getopt1.c, getopt_int.h: Tabify. 2017-04-02 Bruno Haible relocatable-lib-lgpl: Fix link error (regression from 2011-06-16). * modules/relocatable-lib-lgpl (configure.ac): Add AC_LIBOBJ invocation, like it was done in modules/relocatable-lib on 2011-05-21 and in modules/relocatable-prog on 2011-08-15.

Code was using xfreopen to change files to binary mode, but this fails for stdout when in append mode. Such code should use xsetmode instead. * NEWS: Document incompatible changes to binary-io module. * lib/binary-io.c (__gl_setmode_check) [__DJGPP__ || __EMX__]: New function. * lib/binary-io.h (__gl_setmode): Rename from set_binary_mode.

Reported by Tom G. Christensen . 2017-01-30 Paul Eggert Port to PGI 16.10 x86-64 This patch fixes one real bug in gl_anylinked_list2.h, along with some minor glitches that are not bugs. It does not silence PGI’s thousands of bogus warnings when compiling test-intprops.c. Fortunately, the warnings do not cause a failure. * lib/c-ctype.h (_C_CTYPE_LOWER_A_THRU_F_N, _C_CTYPE_LOWER_N): Rename parameter to avoid PGI warning about ‘#define f(n) 'n'’. My goodness, PGI goes back a long ways - this predates C89! * lib/gl_anylinked_list2.h (ASYNCSAFE): Fix bug caught by PGI. For example, ASYNCSAFE (const void *) should expand to ‘const void *volatile’, not to ‘volatile const void *’. * lib/spawn.in.h (POSIX_SPAWN_USEVFORK): Don't define if already defined. * lib/verify.h (verify) [!__GNUC__]: Use shorter albeit meaningless string to bypass silly compiler limits. * tests/infinity.h (Infinityf, Infinityd, Infinityl) [__PGI]: * tests/nan.h (NaNf, NaNd, NaNl): Use static functions to avoid misguided compiler diagnostics. Is there some reason we don’t use static functions on all platforms? 2017-01-20 Paul Eggert parse-datetime: handle timezones reentrantly This API change was prompted by a report by Pádraig Brady in: https://bug.debian.org/851934#10 To help fix the bug, make parse_datetime2 more reentrant. * NEWS: Document this incompatible change. * lib/parse-datetime.h, lib/parse-datetime.y (parse_datetime2): Add two arguments, the timezone and the timezone name. All callers changed. If TZ="..." is specified, use it for calculating defaults. * lib/parse-datetime.y: Don't include xalloc.h or use xmalloc, as this code should be usable in a library. (mktime_ok, get_effective_timezone): Accept timezone arg too. All callers changed. (get_tz): Remove. (get_effective_timezone): Check for failures. 2017-01-20 Eric Blake localename: port to cygwin 2.6 * lib/localename.c (gl_locale_name_thread_unsafe): Add clause for Cygwin. * modules/localename (Depends-on): Add extensions, since NL_LOCALE_NAME() is not visible without it. 2017-01-17 Pádraig Brady parse-datetime: fix dependence on AC_PROG_SED * modules/parse-datetime: Use `sed` directly like all other modules.

On s390x systems, distinguish s390 and s390x. * modules/host-cpu-c-abi (Files): Add m4/asm-underscore.m4. * NEWS: Mention the change regarding 'armel'. 2017-01-15 Paul Eggert localeinfo: case_folded_counterparts and WEOF * NEWS: Document this. * lib/localeinfo.c (case_folded_counterparts): First arg is now wint_t, not wchar_t. This generalizes the function to also work on WEOF, where it returns 0. dfa: port to gcc -fsanitize=undefined * lib/dfa.c (copy): Don’t pass NULL with size 0 to memcpy, as this runs afoul of gcc -fsanitize=undefined. 2017-01-14 Paul Eggert strftime: %z is -00 if unknown * lib/strftime.c (DO_TZ_OFFSET): Omit arg 'negative'; it's now the caller's responsibility to set 'negative_number'. All uses changed. (__strftime_internal): Put '-' before a zero UTC offset if the time zone abbreviation starts with "-", which is the recently-introduced tzdb convention for an unknown UTC offset that is arbitrarily set to 0. * tests/test-strftime.c: Test for this. 2017-01-10 Paul Eggert dfa: port to older GCC Problem reported by Assaf Gordon in: http://lists.gnu.org/r/bug-gnulib/2017-01/msg00103.html * modules/c99: New module. This merely attempts to use the latest C version, which should be enough to solve this particular problem. The idea is to document which Gnulib modules assume C99 or later. * modules/dfa (Depends-on): Add it. 2017-01-10 Bruno Haible Update DEPENDENCIES. * DEPENDENCIES: List only https URLs.

Beebe. * lib/dfa.c (merge): Fix typo that Sun compilers rejected. 2017-01-05 Pádraig Brady parse-datetime: fix generated paths for coverage files * modules/parse-datetime: Adjust the paths for parse-datetime.y within parse-datetime.c, so that gcc generates appropriate .gcno files, allowing lcov to proceed without error. Previously it would error trying to find "lib/lib/parse-datetime.y". 2017-01-05 Pádraig Brady maint.mk: support parallel execution of coverage * top/maint.mk (coverage): Run dependencies serially, thus supporting parallel processing of each one, particularly build-coverage, which builds and runs tests. 2017-01-05 Bruno Haible lock tests: Prefer semaphore over mutex. * tests/test-lock.c (USE_SEMAPHORE): New constant. (struct atomic_int, init_atomic_int, get_atomic_int_value, set_atomic_int_value) [USE_SEMAPHORE]: Define using a POSIX semaphore. Suggested by Torvald Riegel . 2017-01-05 Bruno Haible lock: Provide guarantee to avoid writer starvation for rwlocks. The rationale is: 1) Read-preferring read-write locks are prone to writer starvation if the number of reader threads multiplied by the percentage of time they have the lock held is too high. 2) Write- preferring read-write locks are the only reliable way to avoid this. 3) There have been reports of 'test-lock' hanging on glibc systems http://lists.gnu.org/r/bug-gnulib/2017-01/msg00009.html, and glibc indeed implements read-preferring rwlocks by default, see http://man7.org/linux/man-pages/man3/pthread_rwlockattr_setkind_np.3.html and https://sourceware.org/bugzilla/show_bug.cgi?id=13701 . * m4/pthread_rwlock_rdlock.m4: New file. * m4/lock.m4 (gl_LOCK): Invoke gl_PTHREAD_RWLOCK_RDLOCK_PREFER_WRITER. * lib/glthread/lock.h [USE_POSIX_THREADS]: Test HAVE_PTHREAD_RWLOCK_RDLOCK_PREFER_WRITER. Use a different implementation of rwlock initialization on glibc systems without HAVE_PTHREAD_RWLOCK_RDLOCK_PREFER_WRITER. Use a different implementation of rwlocks altogether on non-glibc systems without HAVE_PTHREAD_RWLOCK_RDLOCK_PREFER_WRITER. [USE_PTH_THREADS]: Use a different implementation of rwlocks altogether. * lib/glthread/lock.c [USE_POSIX_THREADS] (glthread_rwlock_init_for_glibc): New function.

Based on the combination of previously seen tokens, 'digits_to_date_time' determines 2011 to be a year value. This fixes the debug messages to correctly show the updated year. Before: $ date --debug -d 'Apr 11 22:59:00 2011' date: parsed date part: (Y-M-D) 2016-04-11 date: parsed time part: 22:59:00 date: parsed number part: today/this/now After: $ ./src/date --debug -d 'Apr 11 22:59:00 2011' date: parsed date part: (Y-M-D) 2016-04-11 date: parsed time part: 22:59:00 date: parsed number part: year: 2011 * lib/parse-datetime.y (struct parser_control): Add 'year_seen', 'debug_year_seen' member fields. (digits_to_date_time): Update 'year_seen' as needed. (debug_print_current_time): Inform about year updates. (parse_datetime2): Initialize year_seen,debug_year_seen member fields. parse-datetime: fix local timezone debug messages "Local timezones" are strings that affect only DST relative to the default timezone. The debug messages in parse-datetime.y printed wrong information when encountering local timezones. Examples: Here EET/EEST are time zones ('zone' token, with values +02:00/+03:00): TZ=Asia/Tokyo ./src/date --debug -d '2011-12-11 EET' TZ=Asia/Tokyo ./src/date --debug -d '2011-06-11 EEST' When the default timezone relates to the zone strings, EET/EEST are parsed as local timezones (tLOCAL_ZONE), and only change the DST value (0/1, respectively): TZ=Europe/Helsinki ./src/date --debug -d '2011-12-11 EET' TZ=Europe/Helsinki ./src/date --debug -d '2011-06-11 EEST' * lib/parse-datetime.y (debug_print_current_time): If local timezone was seen, inform about DST change, don't print actual timezone. (debug_strfdatetime): If local timezone was seen, use default timezone (and adjust as needed) instead of using incorrect timezone. (parse_datetime2): Use correct time-zone source string, and adjust default timezone as needed. parse-datetime: add debug warning about DST changes Incorrect date arithmetic due to daylight saving time (DST) are a common (false) bug report in coreutils. Detect two such cases and print a warning: 1. year/month/day adjustments (performed on 'struct tm'), where 'mktime' returns a different isdst value. 2. hour/minute/seconds/ns adjustments (performed on 'time_t'), where the result of 'localtime(3)' on the value will return a different isdst value. Note: DST changes could be harmless or unnoticeable. Examples (with 'TZ=America/New_York'): Unnoticeable: result is 2016-Dec-14 $ date -d '2016-06-15 EDT + 6 months' +%b Dec Unnoticeable: result is 2016-Dec-15 11:00:00 $ date -d '2016-06-15 12:00:00 EDT + 6 months' +%F 2016-12-15 This is unexpected: $ date -d '2016-06-01 EDT + 6 months' +%F 2016-11-30 The new debug warnings will show: $ ./src/date --debug -d '2016-06-01 EDT + 6 months' +%F ... date: warning: daylight saving time changed after date adjustment ... * lib/parse-datetime.y (parse_datetime2): Detect DST changes, and print an appropriate warning message. parse-datetime: add debug warning about date arithmetic Date arithmetic are done directly on the fields of 'struct tm', which can result in invalid dates. Normalization with 'mktime(3)' will then produce a different date - which might cause unexpected results. Examples: '2016-10-31 - 1 month' => 2016-09-31 normalized to 2016-10-01. '2016-02-29 + 1 year' => 2017-02-29 normalized to 2017-03-01. Note that date normalization is not inherently wrong and not rejected, as it has legitimate uses: '2016-12-29 + 5 days' => 2016-12-34 noramlized to 2017-01-03. If the user asked to adjust months but 'mday' changed, or user asked to adjust years but 'month' changed - warn about it. $ ./src/date --debug -d '2016-10-31 - 1 month' ... date: warning: when adding relative months/years, \ it is recommended to specify the 15th of the month ... date: warning: month/year adjustment resulted in shifted dates: date: adjusted Y M D: 2016 09 31 date: normalized Y M D: 2010 10 01 ... * lib/parse-datetime.y (parse_datetime2): Detect such cases and print a warning message. Improve recommendation of when to use 15 of the month or noon for date arithmetic. parse-datetime: fix debug message of relative part after timezone Relative part (e.g '+8 days') after a timezone string was not reported (was only reported after a timezone number). Due to the parser's structure, timezone strings with numbers were handled separately. before: # Timezone number + relative part: OK $ ./src/date --debug +%F -d '2013-10-30 00:00:00 +00:00 -8 days' ... date: parsed relative part: -8 day(s) # Timezone string + relative part: missing $ ./src/date --debug +%F -d '2013-10-30 00:00:00 UTC -8 days' [ missing message ] After: messages are printed in both cases. * lib/parse-datetime.y ('zone' token): Call debug_print_relative_time. parse-datetime: fix incorrect debug message on lone number A lone number is an absolute value, not a relative time part. before: $ date --debug -d '20130101' date: parsed number part: today/this/now After: $ ./src/date --debug -d '20130101' date: parsed number part: (Y-M-D) 2013-01-01 * lib/parse-datetime.y ('item'/'number' tokens): Call 'debug_print_current_time' instead of 'debug_print_relative_time'. 2017-01-02 Paul Eggert doc: modernize for C11 etc. * doc/gnulib-readme.texi (Portability guidelines): Modernize a bit for C11, MinGW, etc. This responds to Paul Smith's question in: http://lists.gnu.org/r/bug-gnulib/2017-01/msg00014.html dfa: prefer functions to FETCH_WC macro * lib/dfa.c (FETCH_WC): Remove, replacing with ... (fetch_wc, bracket_fetch_wc): ... new functions. These store the wint_t result into DFA->lex.wctok instead of to a separate arg. All callers changed. Move more local decls closer to where they're used. dfa: narrow more local var scopes * lib/dfa.c: Move more local decls to be more local. dfa: remove duplicate assignment Problem reported by Bruno Haible in: http://lists.gnu.org/r/bug-gnulib/2017-01/msg00007.html * lib/dfa.c (parse_bracket_exp): Simplify. 2017-01-01 Paul Eggert dfa: simplify constraint-dependency checking * lib/dfa.c (prev_newline_constraint, prev_letter_constraint) (prev_other_constraint): Remove. (prev_newline_dependent, prev_letter_dependent): Simplify, to avoid an unnecessary bitwise AND operation. dfa: prefer functions and constants to macros * lib/dfa.c: Prefer constants to macros where either will do. (streq, isasciidigit, newline_constraint) (letter_constraint, other_constraint, succeeds_in_context) (prev_newline_constraint, prev_letter_constraint) (prev_other_constraint, prev_newline_dependent) (prev_letter_dependent, accepting, accepts_in_context): Now static functions instead of function-like macros. Use lower-case names accordingly. All uses changed. dfa: narrow more local var scopes * lib/dfa.c: Move some more local decls down to nearer where they're needed. 2016-12-31 Jim Meyering dfa: narrow the scope of many local variables * lib/dfa.c: Now that we are no longer constrained to c89, move declarations of many variables (often indices) "down" into the scope(s) where used or to the point of definition. This is a no-semantic-change diff. 2017-01-01 Paul Eggert version-etc: new year * build-aux/gendocs.sh (version): * doc/gendocs_template: * doc/gendocs_template_min: * doc/gnulib.texi: * lib/version-etc.c (COPYRIGHT_YEAR): Update copyright dates by hand in templates and the like. * all files: Run 'make update-copyright'. 2016-12-31 Eric Blake do-release-commit-and-tag: avoid shell syntax error * build-aux/do-release-commit-and-tag (curr_br): $branch can contain spaces when rebasing. maint.mk: hoist gnulib_dir definition earlier * top/maint.mk (gnulib_dir): Move near top of file. 2016-12-31 Jim Meyering maint.mk: do not always evaluate intprops-related shell * top/maint.mk (_intprops_names): Change := to just "=" to avoid using gnulib_dir undefined (gnulib_dir is defined later in the file, which will be fixed separately), and besides, there is no need to incur the cost of this shell invocation for every single use of this .mk file. Reported by Eric Blake in https://lists.gnu.org/r/bug-gnulib/2016-12/msg00137.html 2016-12-30 Jim Meyering maint.mk: improve sc_prohibit_intprops_without_use * top/maint.mk (_intprops_names): Don't hard-code the list of symbol names. Instead, derive it on the fly. 2016-12-30 Paul Eggert dfa: shorten sbit, success * lib/dfa.c (struct regex_syntax.sbit): (struct dfa.success): Use char, not int, for array elements, since they are all in the range 0..7. dfa: simplify multibyte_prop etc. This follows up on a change made when dfa.c was in grep, namely grep commit c797046c7c13c2647182b919a79a4c5b4ecf82b1 dated 2015-08-12 07:35:03 -0700, which removed unused multibyte support. That earlier simplification allows for some more simplification and trimming down here. * lib/dfa.c (struct mb_char_classes): New member nchars_alloc. (struct lexer_state): New mamber brack. (struct dfa, addtok_mb): multibyte_prop elements are now char, not int, since they must be in the range 0..3 now. Remove members mbcsets, nmbcsets, mbcsets_alloc, since the brack member now supersedes them. (parse_bracket_exp): Update dfa->lex.brack instead of dfa->mbcsets. (addtok): Use dfa->lex.brack instead of dfa->mbcsets. (dfaparse): Remove unnecessary initializations of already-0 storage. (free_mbdata): Free d->lex.brack.chars instead of d->mbcsets. (dfassbuild): No need to clear sup->mbcsets. dfa: minor performance tweak * lib/dfa.c (setbit_wc): Test < 0, not == EOF. dfa: wrap charclass inside a struct On my platform (gcc Ubuntu 5.4.0-6ubuntu1~16.04.4 x86-64, en_US.utf8 locale) this makes 'grep -Fi -f list.txt list.txt >out' about 5% faster, where list.txt is generated by 'aspell dump master | head -n 100000 >list.txt'. See Bug#22239. * lib/dfa.c (charclass): Wrap inside a struct. All uses changed. (CHARCLASS_INIT, tstbit, setbit, clrbit, zeroset, fillset, notset) (equal, emptyset, charclass_index, setbit_wc, setbit_case_fold_c): Adjust to this, e.g., by using charclass * rather than charclass. All callers changed as needed. (copyset): Remove. All uses changed to simple assignment. (parse_bracket_exp): Use zeroset instead of memset. 2016-12-30 Jim Meyering maint.mk: update list of intprops.h symbol names * top/maint.mk (_intprops_names): Regenerate the list of symbol names. This avoids a false failure of the sc_prohibit_intprops_without_use rule in grep. 2016-12-29 Eric Blake getopt: fix parallel test failure * tests/test-getopt-posix.c (TEST_GETOPT_TMP_NAME): Set name. * tests/test-getopt-gnu.c (TEST_GETOPT_TMP_NAME): Likewise. * tests/test-getopt-main.h (main): Use different file names in case test-getopt-gnu and test-getopt-posix run in parallel. 2016-12-29 Paul Eggert xalloc: x2nrealloc check for ptrdiff_t overflow * lib/xalloc.h (x2nrealloc): Check for ptrdiff_t overflow, too. * modules/xalloc, modules/xvasprintf (Depends-on): Add stdint. 2016-12-24 Bruno Haible lock test: Fix performance problem on multi-core machines. * tests/test-lock.c (USE_VOLATILE): New macro. (struct atomic_int): New type. (init_atomic_int, get_atomic_int_value, set_atomic_int_value): New functions. (lock_checker_done, rwlock_checker_done, reclock_checker_done): Define as 'struct atomic_int'. (lock_checker_thread, test_lock, rwlock_checker_thread, test_rwlock, reclock_checker_thread, test_recursive_lock): Use the new functions. Reported by Eric Blake in https://www.redhat.com/archives/libvir-list/2012-March/msg00854.html and by Pádraig Brady in http://lists.gnu.org/r/bug-gnulib/2016-12/msg00117.html. 2016-12-19 Bruno Haible vma-iter: Fix endless loop on 64-bit Windows. * lib/vma-iter.c (vma_iterate): On Windows, use 'uintptr_t' instead of 'unsigned long'. 2016-12-19 Bruno Haible stdint: Fix WINT_MAX to match the gnulib provided wint_t on minw. * m4/wint_t.m4 (gt_TYPE_WINT_T): Define GNULIB_OVERRIDES_WINT_T here. * m4/stdint.m4 (gl_STDINT_H): Don't define GNULIB_OVERRIDES_WINT_T.

I suspect that the typo explains this build failure: https://buildfarm.opencsw.org/buildbot/builders/ggrep-solaris10-sparc/builds/39 although I can’t reproduce the problem on Solaris 10 sparc. 2016-12-18 Paul Eggert dfa: improve worst-case 'replace' performance See my note in Bug#22357#71. * lib/dfa.c (insert, delete): Rework to avoid duplicate test. (merge_constrained): New function, which is like the old 'merge' function, except with a new argument C2. Simplify the body by avoiding the need for different sections of code depending on whether one input is exhausted. (merge): Use the new function. (delete): Return the constraint of the deleted position, not the entire position. Caller changed. (replace): Change from O(N*(N + log N)) to O(N log N) algorithm. 2016-12-18 Norihiro Tanaka dfa: performance improvement for removal of epsilon closure See Bug#22357#32. * lib/dfa.c (delete): Use binary search to find deleted index.

Problem reported by Eli Zaretskii in: http://lists.gnu.org/r/emacs-devel/2016-12/msg00642.html Is Plan 9 still a valid porting target, anyway? 2016-12-15 Paul Eggert safe-alloc: use xalloc-oversized * lib/safe-alloc.c: Include xalloc-oversized.h. (safe_alloc_oversized): Remove. All uses changed to xalloc_oversized. * modules/safe-alloc (Depends-on): Add xalloc-oversized. xalloc: do not exceed PTRDIFF_MAX * lib/xmalloc.c (xcalloc) [HAVE_GNU_CALLOC]: Do not omit xalloc_oversized check, since objects larger than PTRDIFF_MAX bytes have pointer-subtraction problems. malloca: do not exceed PTRDIFF_MAX * lib/malloca.h: Include xalloc-oversized. (nmalloca): Use xalloc_oversized instead of rolling our own. * modules/malloca (Depends-on): * modules/relocatable-prog-wrapper (Depends-on): Add xalloc-oversized. quotearg: pacify GCC better * modules/quotearg (Depends-on): Add minmax, stdint. * lib/quotearg.c: Include minmax.h, stdint.h. (nslots): Now int, as there seems little point to going to extra work merely to support the INT_MAX slot, which nobody ever uses. (quotearg_n_options): Redo size-overflow checks to pacify GCC and to catch (mostly-theoretical) ptrdiff_t problems too. This can be done via one comparison. 2016-12-14 Paul Eggert xalloc-oversized: check for PTRDIFF_MAX too This avoids undefined behavior when subtracting pointers to objects containing more than PTRDIFF_MAX bytes. * lib/xalloc-oversized.h (__xalloc_oversized, xalloc_oversized): Also return 1 if the result would exceed PTRDIFF_MAX> * modules/xalloc-oversized (Depends-on): Add stdint. dfa: fix glitches in previous commit Sorry, I don't know how I managed to commit the wrong version. * lib/dfa.c (MIN): Move up. (xpalloc): Now static. dfa: fix some unlikely integer overflows I found these while reviewing the recent Coverity-related fix. This patch changes part of dfa.c to prefer ptrdiff_t instead of size_t for object counts. Using ptrdiff_t is the style typically used in Emacs; although it wastes a sign bit as sizes can never be negative, it makes -fsanitize=undefined more likely to catch integer overflows in index calculation, and nowadays the upside is typically more important than the downside. Although perhaps the rest of dfa.c should be changed to prefer ptrdiff_t as well (much of dfa.c already does, since it uses state_num which is signed), that is a bigger change and is not needed to fix the bugs I found. * lib/dfa.c: Include stdint.h and intprops.h. (TOKEN_MAX): New macro. (position_set, struct mb_char_classes, struct dfa, maybe_realloc) (charclass_index, parse_bracket_exp, addtok, insert, merge) (realloc_trans_if_necessary, free_mbdata): Use ptrdiff_t instead of size_t for object counts related to xpalloc. This is safe because xpalloc checks that the sizes do not exceed either SIZE_MAX or PTRDIFF_MAX. (xpalloc): New function, mostly taken from Emacs. (maybe_realloc, copy, realloc_trans_if_necessary): Use it. (maybe_realloc): Add NITEMS_MAX to signature. All callers changed. (charclass_index): Check for integer overflow in computing charclass index; it must not exceed TOKEN_MAX - CSET, as CSET is added to it later. (alloc_position_set): Check for integer overflow. On typical platforms this check has zero overhead, since the constant expression is false. (realloc_trans_if_necessary): Remove assertion, which I hope Coverity no longer needs. * modules/dfa (Depends-on): Add intprops, stdint. 2016-12-12 Jim Meyering dfa: add an assertion to avoid coverity false positive * lib/dfa.c (realloc_trans_if_necessary): Otherwise, coverity warned that "newalloc1 - 2" could overflow. 2016-12-13 Arnold D. Robbins dfa: remove DFA_CASE_FOLD flag in favor of RE_ICASE * dfa.h (DFA_CASE_FOLD): Remove. * dfa.c (dfasyntax): Set dfa->syntax.case_fold based on RE_ICASE. 2016-12-13 John W.

That would lead to an infinite loop. The solution is to update "matched" when necessary. Introduced by commit v0.1-983-g403adf1. 2016-11-27 Norihiro Tanaka dfa: avoid match middle in multibyte character * lib/dfa.c (transit_state): If fails in matching single byte characters on a state including period expression in non-UTF8 multibyte locales, skip trailing bytes.

The simplest solution is to restore the TOO_EXPENSIVE heuristic that I added to GNU diff in 1993, while using a higher threshold to avoid Bug#16848 on smaller files. * lib/diffseq.h (struct context): Restore member too_expensive. (struct partition): Restore members lo_minimal, hi_minimal. (diag, compareseq): Restore arg find_minimal. All uses changed. (diag): Restore the TOO_EXPENSIVE heuristic that I added back in 1993 to make 'diff' run faster (but not as well) on large inputs, but use a threshold of 4096 instead of the old 256. * lib/fstrcmp.c (strcmp_bounded): * lib/git-merge-changelog.c (compute_differences): Adjust to diffseq.h changes. 2016-10-22 Bruno Haible iconv: Avoid compilation error when bootstrapping GNU libiconv. * m4/iconv.m4 (AM_ICONV): When the system does not have an iconv() declaration yet, define ICONV_CONST to empty. 2016-10-15 Bruno Haible Avoid gnulib-tool warnings about the dependencies of 'parse-datetime'. * gnulib-tool (func_get_license): Special-case the 'parse-datetime' module. 2016-10-16 Bruno Haible system-quote tests: Avoid compiler warning on AIX. * tests/test-system-quote-child.c (fopen): Redefine like the system's does. 2016-10-16 Bruno Haible Fix some "gcc -Wall" warnings. * tests/test-ffsl.c (main): Use variable x, not i. * tests/test-posix_spawn3.c (parent_main): Consider the return value of freopen. * tests/test-sethostname1.c (main): Explicitly ignore the return value of sethostname. 2016-10-16 Bruno Haible gnulib-tool: Make --create-testdir on all modules work again. * gnulib-tool (func_create_testdir): Don't include the non-recursive-gnulib-prefix-hack module. 2016-10-21 Daiki Ueno libunistring: change the maintainer to 'all' * modules/gen-uni-tables, modules/libunistring: * modules/ucs4-utf16, modules/ucs4-utf8, modules/unicodeio: * modules/unitypes, modules/utf16-ucs4, modules/utf16-ucs4-unsafe: * modules/utf8-ucs4, modules/utf8-ucs4-unsafe: * modules/unicase/*, modules/uniconv/*, modules/unictype/*: * modules/unilbrk/*, modules/uniname/*, modules/uninorm/*: * modules/unistdio/*, modules/unistr/*, modules/uniwbrk/*: * modules/uniwidth/*: Change the maintainer to 'all'. 2016-10-16 Bruno Haible Simplify "configure: checking ..." messages. * m4/fsusage.m4 (gl_FILE_SYSTEM_USAGE): Use AC_MSG_CHECKING instead of AC_MSG_NOTICE. * m4/getaddrinfo.m4 (gl_GETADDRINFO): Likewise. 2016-10-20 Paul Eggert quotearg-tests: pacify gcc -Wall Problem reported by Bruno Haible in: http://lists.gnu.org/r/bug-gnulib/2016-10/msg00066.html * tests/test-quotearg-simple.c (use_quote_double_quotes): Move here ... * tests/test-quotearg.h: ... from here. 2016-10-20 Pádraig Brady canonicalize-lgpl: fix for missing SIZE_MAX on older systems * lib/canonicalize-lgpl.c [SIZE_MAX]: Define if needed.

This is significant for sh-quote, which has separate routines to determine the length and do the actual quoting. * tests/test-quotearg.h: Reinstate the buffer bounds checking now that we never write more than the returned length. 2016-10-18 Bruno Haible getprogname tests: Avoid failure in packages that use libtool. * tests/test-getprogname.c (main): Strip "lt-" prefix. Based on a patch by Jim Meyering. 2016-10-16 Bruno Haible getprogname: Fix test failure on Cygwin. Comments. * lib/getprogname.h: Add comments. * lib/getprogname.c: Add comments.

(main): Adjust for the new more concise quoting style. Reported by Bruno Haible. 2016-10-16 Jim Meyering non-recursive-gnulib-prefix-hack: fix inconsequential typo * m4/non-recursive-gnulib-prefix-hack.m4: Change a hard-coded "lib" to "$1".

See: http://lists.gnu.org/r/emacs-devel/2016-09/msg00416.html 2016-09-15 Eric Blake sys_types: avoid glibc 2.25 warnings about major() * m4/sys_types_h.m4 (AC_HEADER_MAJOR): Replace broken version in older autoconf. * doc/posix-headers/sys_types.texi (sys/types.h): Document fix. * doc/glibc-functions/gnu_dev_major.texi (gnu_dev_major): Likewise. * doc/glibc-functions/gnu_dev_makedev.texi (gnu_dev_makedev): Likewise. * doc/glibc-functions/gnu_dev_minor.texi (gnu_dev_minor): Likewise. mountlist: include sysmacros.h for glibc * m4/mountlist.m4 (gl_PREREQ_MOUTLIST_EXTRA): Include AC_HEADER_MAJOR. * lib/mountlist.c (includes): Use correct headers. 2016-09-15 Paul Eggert extensions: port to more ISO C TSes * m4/extensions.m4 (AC_USE_SYSTEM_EXTENSIONS): Sync from Autoconf master, to add support for more recent ISO C TRs and TSes. 2016-09-13 Paul Eggert intprops: new macro TYPE_WIDTH * lib/intprops.h (TYPE_WIDTH): New macro. (TYPE_MAXIMUM, _GL_SIGNED_INT_MAXIMUM, INT_STRLEN_BOUND): * lib/ftoastr.h (_GL_FLOAT_DIG_BITS_BOUND): * lib/parse-datetime.y (parse_datetime2): Use it. extensions: port to recent ISO C TRs * m4/extensions.m4 (AC_USE_SYSTEM_EXTENSIONS): Sync from Autoconf master, to add support for recent ISO C TRs. * m4/stdio_h.m4 (gl_STDIO_H): Define __USE_MINGW_ANSI_STDIO here, since AC_USE_SYSTEM_EXTENSIONS no longer does that as the MinGW option is not an extension. 2016-09-11 Paul Eggert dfa: port to Solaris 9 Problems reported by Tom G. Christensen in: http://lists.gnu.org/r/bug-gnulib/2016-09/msg00031.html * modules/dfa (Depends-on): Add isblank. * modules/dfa-tests (dfa_match_aux_LDADD): Rename from test_stat_LDADD, to fix typo. * tests/dfa-match.sh: Don't require 'timeout'; use it if available. 2016-09-10 Jim Meyering strverscmp: avoid link failure on OS X * lib/strverscmp.c [!weak_alias]: Define __strverscmp to strverscmp. Reported by Assaf Gordon in https://bugs.gnu.org/24256#26 2016-08-16 Jim Meyering dfa: new module, importing grep's DFA matcher Since grep's DFA matcher is now being used by two gnulib-enabled projects, grep and sed, it makes sense to version-control its sources and unit tests in one place: here. * modules/dfa: New module. * modules/dfa-tests: New file. * lib/dfa.c: New file, from grep. * lib/dfa.h: Likewise. * lib/localeinfo.c: Likewise. * lib/localeinfo.h: Likewise. * tests/dfa-match-aux.c: Likewise. * tests/dfa-invalid-char-class.sh: Likewise. * tests/dfa-match.sh: Likewise, with minor changes. * MODULES.html.sh (Misc): Add "dfa" to this list. 2016-09-09 Jim Meyering getprogname-tests: don't depend on assert-h * modules/getprogname-tests (Depends-on): Remove assert-h. It was not needed, and in fact would cause build failure for coreutils on some systems. Reported by Assaf Gordon in https: //lists.gnu.org/r/coreutils/2016-09/msg00016.html 2016-09-07 Jim Meyering getprogname-tests: work also when EXEEXT is nonempty * modules/getprogname-tests (Makefile.am): Define EXEEXT. * tests/test-getprogname.c (main): Use it. Suggested by Gisle Vanem. 2016-09-07 Gisle Vanem getprogname: fix errors in previous change * lib/getprogname.c (getprogname) [HAVE_GETEXECNAME]: s/program_invocation_name/base/ [HAVE_DECL___ARGV]: Handle NULL __argv or __argv[0]. 2016-09-08 Pádraig Brady parse-datetime: restrict debug output to input string * lib/parse-datetime.y (parse_datetime2): If we parse all of the input but determine it's invalid, ensure we don't output the now invalid input pointer. This issue was seen with `date -d 'now +1'`. 2016-09-07 Paul Eggert flexmember: new macro FLEXALIGNOF * lib/flexmember.h: Include , for offsetof. (FLEXALIGNOF): Rename from _GL_XALLOC_ALIGNOF, as Emacs can use this macro. Update comments. 2016-09-07 Jim Meyering getprogname: port to systems with __argv (mingw, msvc) * lib/getprogname.c (getprogname): Include "dirname.h" and use last_component: more general than open coding it with hard-coded "/". * lib/getprogname.h (getprogname): Prefer "char const *" consistently. * modules/getprogname (Depends-on): Add dirname-lgpl. (configure.ac): Check for __argv in . * modules/getprogname-tests: New file. * tests/test-getprogname.c: New file. Suggested by Gisle Vanem in https://lists.gnu.org/r/bug-gnulib/2016-09/msg00014.html 2016-09-07 Paul Eggert flexmember: port better to GCC + valgrind With a char[] flexible array member in a struct with nontrivial alignment, GCC-generated code can access past the end of the array, because GCC assumes there are padding bytes to get the struct aligned. So the common idiom of malloc (offsetof (struct s, m), n) does not properly allocate an n-byte trailing member, as malloc’s argument should be the next multiple of alignof (struct s). See GCC Bug#66661: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66661 Although C11 apparently permits this GCC optimization (i.e., there was a bug in Gnulib not in GCC), possibly this is a defect in C11. See the thread containing: https://gcc.gnu.org/ml/gcc-patches/2016-09/msg00317.html * lib/flexmember.h: New file. * lib/fnmatch.c, lib/fts.c, lib/glob.c, lib/idcache.c: * lib/localename.c, lib/time_rz.c: Include flexmember.h. * lib/fnmatch_loop.c (struct patternlist): * lib/localename.c (struct hash_node): Use FLEXIBLE_ARRAY_MEMBER. * lib/fnmatch_loop.c (EXT): * lib/fts.c (fts_alloc): * lib/glob.c (glob_in_dir): * lib/idcache.c (getuser, getuidbyname, getgroup, getgidbyname): * lib/localename.c (gl_lock_define_initialized): * lib/time_rz.c (tzalloc): Use FLEXSIZEOF instead of offsetof. * m4/flexmember.m4 (AC_C_FLEXIBLE_ARRAY_MEMBER): Check that the size of the struct can be taken. * modules/flexmember (Files): Add lib/flexmember.h. * modules/fnmatch, modules/glob, modules/localename (Depends-on): Add flexmember. 2016-09-06 Paul Eggert getprogname: port to Solaris 10 * lib/getprogname.c: Include stdlib.h, for getexecname decl. (getprogname) [HAVE_GETEXECNAME]: Use that, for Solaris 10. * m4/getprogname.m4 (gl_FUNC_GETPROGNAME): Check for getexecname. stdalign: correct mistake in alignof doc Problem reported by Joseph Myers in: https://gcc.gnu.org/ml/gcc-patches/2016-09/msg00340.html * doc/posix-headers/stdalign.texi: Do not imply that C11 prohibits alignof(S) where S is a structure containing a flexible array member. The Gnulib substitute does not support this, but C11 does. 2016-08-18 Pino Toscano main.mk: remove sc_program_name, since there is no more need to use set_program_name in tools (getprogname is enough for most of the cases). * cfg.mk (local-checks-to-skip): Remove sc_program_name. * top/maint.mk (sc_program_name): Remove. 2016-08-18 Pino Toscano Port tests away from progname, since modules that need the program name already depend on getprogname. * modules/acl-tests (Depends-on): Remove progname. * modules/argmatch (Depends-on): Likewise. * modules/argmatch-tests (Depends-on): Likewise. * modules/argp-tests (Depends-on): Likewise. * modules/argp-version-etc-tests (Depends-on): Likewise. * modules/array-list-tests (Depends-on): Likewise. * modules/array-oset-tests (Depends-on): Likewise. * modules/avltree-list-tests (Depends-on): Likewise. * modules/avltree-oset-tests (Depends-on): Likewise. * modules/avltreehash-list-tests (Depends-on): Likewise. * modules/carray-list-tests (Depends-on): Likewise. * modules/copy-file-tests (Depends-on): Likewise. * modules/exclude-tests (Depends-on): Likewise. * modules/fchownat-tests (Depends-on): Likewise. * modules/fdopendir-tests (Depends-on): Likewise. * modules/filenamecat-tests (Depends-on): Likewise. * modules/fstatat-tests (Depends-on): Likewise. * modules/fstrcmp-tests (Depends-on): Likewise. * modules/linked-list-tests (Depends-on): Likewise. * modules/linkedhash-list-tests (Depends-on): Likewise. * modules/mkdirat-tests (Depends-on): Likewise. * modules/nonblocking-pipe-tests (Depends-on): Likewise. * modules/nonblocking-socket-tests (Depends-on): Likewise. * modules/obstack-printf-tests (Depends-on): Likewise. * modules/openat-tests (Depends-on): Likewise. * modules/parse-datetime-tests (Depends-on): Likewise. * modules/pipe-filter-gi-tests (Depends-on): Likewise. * modules/pipe-filter-ii-tests (Depends-on): Likewise. * modules/quotearg-simple-tests (Depends-on): Likewise. * modules/quotearg-tests (Depends-on): Likewise. * modules/rbtree-list-tests (Depends-on): Likewise. * modules/rbtree-oset-tests (Depends-on): Likewise. * modules/rbtreehash-list-tests (Depends-on): Likewise. * modules/spawn-pipe-tests (Depends-on): Likewise. * modules/system-quote-tests (Depends-on): Likewise. * modules/uniname/uniname-tests (Depends-on): Likewise. * modules/uninorm/nfc-tests (Depends-on): Likewise. * modules/uninorm/nfd-tests (Depends-on): Likewise. * modules/uninorm/nfkc-tests (Depends-on): Likewise. * modules/uninorm/nfkd-tests (Depends-on): Likewise. * modules/unistdio/u16-vsnprintf-tests (Depends-on): Likewise. * modules/unistdio/u16-vsprintf-tests (Depends-on): Likewise. * modules/unistdio/u32-vsnprintf-tests (Depends-on): Likewise. * modules/unistdio/u32-vsprintf-tests (Depends-on): Likewise. * modules/unistdio/u8-vsnprintf-tests (Depends-on): Likewise. * modules/unistdio/u8-vsprintf-tests (Depends-on): Likewise. * modules/unistdio/ulc-vsnprintf-tests (Depends-on): Likewise. * modules/unistdio/ulc-vsprintf-tests (Depends-on): Likewise. * modules/unlinkat-tests (Depends-on): Likewise. * modules/version-etc-tests (Depends-on): Likewise. * modules/xalloc-die-tests (Depends-on): Likewise. * modules/xmemdup0-tests (Depends-on): Likewise. * modules/xprintf-posix-tests (Depends-on): Likewise. * modules/xvasprintf-tests (Depends-on): Likewise. * tests/test-argmatch.c: Do not include progname.h.

Quoting the manual, "Compiling with -fno-common is useful on targets for which it provides better performance, or if you wish to verify that the program will work on other systems that always treat uninitialized variable declarations this way [putting it in the data section]." If diffutils had been using this sooner, it would have prevented this duplicate declaration issue: http://git.sv.gnu.org/cgit/diffutils.git/commit/?id=v3.4-10-gc2dc91f 2016-08-31 Simon Josefsson parse-datetime: Fix typo. * lib/parse-datetime.y (parse_datetime2): Fix typo. 2016-08-30 Paul Eggert intprops: tune INT_NEGATE_OVERFLOW for GCC 5 and 6 * lib/intprops.h (INT_NEGATE_OVERFLOW): Tune for platforms like GCC 5 and 6 that have __builtin_sub_overflow but not __builtin_sub_overflow_p. With the recent changes, these platforms are a tiny bit faster with the INT_NEGATE_RANGE_OVERFLOW implementation than with INT_SUBTRACT_OVERFLOW implementation, since the former needs just one runtime comparison whereas the latter needs two. strverscmp: sync with glibc Although this doesn't exactly synchronize with glibc byte-for-byte, it makes the code behave the same as glibc. * lib/strverscmp.c (S_I, S_F, S_Z): Now masks, not powers of 2. (ISDIGIT): Remove, as glibc is sticking with isdigit, and the difference shouldn't matter in practical use. All uses changed back to isdigit. (__strverscmp, strverscmp): Use new glibc method for weak aliases. (next_state): Now unsigned char array; redo elements. (result_type): Now signed char array; redo elements. (__strverscmp): Fix glibc bug 9913 by using new states. * tests/test-strverscmp.c (main): Test glibc bug 9913. 2016-08-29 Jim Meyering xalloc-oversized.h: port __builtin_mul_overflow change to GCC 6.2.0 * lib/xalloc-oversized.h: Port this change to GCC 6.2.0, too, similarly to how it was done to intprops.h. 2016-08-29 Paul Eggert intprops.h: port recent changes to GCC 6.2.0 * lib/intprops.h (__has_builtin): Move earlier. (_GL_HAS_BUILTIN_OVERFLOW): Rename from _GL_HAS_BUILTIN_OVERFLOW_WITH_NULL and don't worry about whether the last argument can be null. All uses changed. (_GL_HAS_BUILTIN_OVERFLOW_P): Also test __has_builtin. (_GL_ADD_OVERFLOW, _GL_SUBTRACT_OVERFLOW, _GL_MULTIPLY_OVERFLOW): Don't try to use 3rd arg null, as this doesn't work on GCC 6.2.0 and it's not clear which GCC versions it works for. (_GL_INT_OP_WRAPV): Use _GL_HAS_BUILTIN_OVERFLOW instead of its definiens. intprops.h: use __typeof__ with GCC 7 * lib/intprops.h (_GL_ADD_OVERFLOW, _GL_SUBTRACT_OVERFLOW) (_GL_MULTIPLY_OVERFLOW): Use __typeof__ as in the GCC manual. This avoids computing the expression's value (which might overflow!). 2016-08-29 Jim Meyering intprops.h, xalloc-oversized.h: work with gcc 7 In gcc 6, __builtin_add_overflow, __builtin_sub_overflow and __builtin_mul_overflow each accept a NULL pointer as the third argument. However in gcc 7, that is no longer accepted. Instead, one must use the "_p"-suffixed names, with which, the third parameter is no longer a pointer. * lib/intprops.h (_GL_HAS_BUILTIN_OVERFLOW_WITH_NULL): Correct the definition: not true for gcc 7 and subsequent. (_GL_HAS_BUILTIN_OVERFLOW_P): Define. (_GL_ADD_OVERFLOW, _GL_SUBTRACT_OVERFLOW, _GL_MULTIPLY_OVERFLOW): Provide new definitions for gcc 7 and subsequent. * lib/xalloc-oversized.h (xalloc_oversized): Provide a definition that works with gcc-7. intprops.h: fix missing-backslash problems * lib/intprops.h (_GL_ADD_OVERFLOW): Add backslash. (_GL_SUBTRACT_OVERFLOW,_GL_MULTIPLY_OVERFLOW): Likewise. 2016-08-24 Paul Eggert intprops: fix paren typo on old platforms Problem reported by John E. Malmberg in: https://bugs.gnu.org/24300#13 * lib/intprops.h (_GL_INT_OP_WRAPV_LONGISH) [__GNUC__ < 5 && !__has_builtin (__builtin_add_overflow) && (__STDC_VERSION__ < 201112 || _GL__GENERIC_BOGUS) && !defined LLONG_MAX]: Remove stray paren. intprops: port to OpenVMS Problem reported by John E. Malmberg in: https://bugs.gnu.org/24300 * doc/posix-headers/limits.texi: Document the problem. * lib/intprops.h (LLONG_MAX, LLONG_MIN) [__INT64_MAX]: Define if not already defined. 2016-08-19 Assaf Gordon parse-datetime: improve debug implementation Follow-up to commit 12ad79069 ("add optional debug printing"). Improve parse-datetime's debug implementation: remove macros, replace global debug flag variable with a function parameter, use nstrftime for formatting. See: https://lists.gnu.org/r/bug-gnulib/2016-08/msg00021.html * lib/parse-datetime.h: (parse_datetime_debug): Remove global extern. (parse_datetime2): New function, accepts 'flags' parameter, supporting debug flag. Existing interface 'parse_datetime' left unmodified. * lib/parse-datetime.c: (parse_datetime_debug): Remove global variable. (struct parser_control): add 'parse_datetime_debug' member variable. (parse_datetime): Call new function 'parse_datetime2' without debug. (parse_datetime2): Adapted from previous 'parse_datetime', initialize pc.parse_datetime_debug variable as needed. (to_year): Accept new flags parameter, instead of using global variable. (debug_print_current_time,debug_print_relative_time,debug_mktime_not_ok): use struct 'debug' variable instead of global variable. (DEBUG,DEBUG_PRINT_CURRENT_TIME,DEBUG_PRINT_RELATIVE_TIME, DEBUG_MKTIME_NOT_OK,PROGRESS,PROGRESS0): Remove macros. Call correspnding functions directly instead of using macros. * modules/parse-datetime: Add gnulib's strftime module. 2016-08-19 Daniel Richard G. c-strcase-tests: port to EBCDIC * tests/test-c-strncasecmp.c: Allow two c_strncasecmp calls which assume ASCII encoding semantics to run only in ASCII mode, as they fail in EBCDIC. sigpipe-tests: fix typo * tests/test-sigpipe.sh: C, not B. 2016-08-18 Paul Eggert canonicalize-lgpl: fix errno after malloca fails This fixes a typo I recently introduced. Suggested by Bruno Haible in: http://lists.gnu.org/r/bug-gnulib/2016-08/msg00039.html * lib/canonicalize-lgpl.c (__realpath): Don't assume malloca sets errno on failure. 2016-08-17 Paul Eggert strtod: port errno handling to z/OS * lib/strtod.c (strtod): Save and restore errno more reliably. 2016-08-17 Daniel Richard G. strtod: port to z/OS * lib/strtod.c (strtod): Address a couple quirks in the z/OS implementation. 2016-08-17 Paul Eggert strtod: port to z/OS * lib/strtod.c (strtod): Address a couple quirks in the z/OS implementation. regex, string: rename to avoid '__string' * lib/regex.h, lib/string.in.h: Do not use the identifier '__string', as it is effectively reserved by string.h on z/OS. c-strcase-tests, wcwidth-tests: depend on c-ctype * modules/c-strcase-tests, modules/wcwidth-tests (Depends-on): Add c-ctype. 2016-08-17 Daniel Richard G. thread: port to z/OS * lib/glthread/thread.c, lib/glthread/thread.h: Rudimentary gl_thread support for z/OS. maint: port tests to z/OS errno behavior * tests/test-nonblocking-reader.h: * tests/test-nonblocking-writer.h: Accommodate z/OS errno code preferences. (I believe this should still be within spec; IBM is good at following the letter if not the spirit of such things.) maint: preprocessor changes to support z/OS * lib/alloca.in.h, lib/fnmatch.c, lib/get-rusage-as.c: * lib/glob.c, lib/math.in.h, lib/ptsname_r.c: * tests/infinity.h, tests/nan.h, tests/test-canonicalize-lgpl.c: * tests/test-nonblocking-pipe.h: fclose, strstr-simple, wchar: port to z/OS * m4/fclose.m4, m4/strstr.m4, m4/wchar_h.m4: Changes to the Autoconf M4 code to support z/OS. Note that fclose() is broken in a different way on z/OS than it is on other systems, thus the special-case in fclose.m4. iconv_open-utf-tests, iconv-tests: port to EBCDIC * tests/test-iconv-utf.c, tests/test-iconv.c: Added appropriately conditional #pragmas so that the test strings in test-iconv-utf.c are correctly interpreted in ASCII instead of EBCDIC (i.e. 'J' == 0x4A and not 0xD1). This issue could be addressed in a more portable way by simply rewriting all the ASCII literal characters as octal escapes, but then you would lose the partial readability that the strings have now. Also, iconv_open() on z/OS does not recognize "ISO-8859-1", but "ISO8859-1" works. c-strcase-tests, wcwidth-tests: port to EBCDIC * tests/test-c-strcasecmp.c: Include c-ctype.h. (main) [!C_CTYPE_ASCII]: Skip tests that assume ASCII. * tests/test-wcwidth.c: Likewise. 2016-08-17 Paul Eggert stdbool: don't require _Bool for C++ Problem reported by David Seifert in: http://lists.gnu.org/r/bug-gnulib/2016-06/msg00005.html * NEWS, doc/posix-headers/stdbool.texi (stdbool.h): Document this. * m4/stdbool.m4 (AC_CHECK_HEADER_STDBOOL): Make the check more-forgiving for C++, in that it requires only 'bool'. Be a bit stricter about checking that bool and _Bool are compatible in C. 2016-08-16 Paul Eggert getdelim: remove dependency on realloc-posix * lib/canonicalize-lgpl.c (alloc_failed) [!FUNC_REALPATH_WORKS || defined _LIBC]: New function, (__realpath) [!FUNC_REALPATH_WORKS || defined _LIBC]: Use it. Use __set_errno where needed, for consistency. * lib/getdelim.c (alloc_failed): New function. (getdelim): Use it. 2016-08-09 Assaf Gordon parse-datetime: add optional debug printing Print parsing information, warnings, and errors to stderr. * lib/parse-datetime.h (parse_datetimte_debug): New global variable. * lib/parse-datetime.y: (DEBUG_*): Macros calling debug functions if debugging is enabled. (PROGRESS*): Same as DEBUG, for progress reporting. (dbg_printf): Print message to stderr, with 'date' prefix. (struct parser_control): Add 'debug_*_seen' variables. (str_days): Converts day ordinal/number to string (e.g. 'last wed'). (debug_print_current_time, debug_print_relateive_time): Prints the current/relative date/time value of parser_control. (YACC parser syntax): Print parsed parts with DEBUG_* macros. (to_year): Warn about 2-digit year parsing. (yylex): Warn about unrecognized words. (get_effective_timezone): Returns current timezone in minutes. (debug_strf{time,date,datetime}): Convert 'struct tm' to string as clearly and unambigiously as possible. (debug_mktime_not_ok): Print detailed information about failed date/time values. (parse_datetime): Add DEBUG messages for failures, warnings. Add PROGRESS messages for status messages. * modules/parse-datetime: Add 'timegm', 'gettext-h' dependencies. 2016-08-06 Jim Meyering tests/init.sh: exclude dash with bad "local" semantics * tests/init.sh (gl_shell_test_script_): Add a function to eliminate a shell like "dash" (unlike bash, zsh) that has surprising/risky "local var='...'" semantics. Inspired by the problem and discussion in https://bugs.gnu.org/24116#11. 2016-08-02 Ján Tomko maint.mk: expand the prohibit_doubled_word regex This check has a static list of words that are checked for repetitions. Expand it before running the perl script to avoid using expensive captures. This decreases the cost for libvirt from 1.66s to 0.66s. * top/maint.mk (prohibit_doubled_word_expanded_): Define. (sc_prohibit_doubled_word): Use it. 2016-07-26 Ján Tomko useless-if-before-free: skip non-matching lines early * build-aux/useless-if-before-free: First match each line with the simple/quick /\bif\b/ and reject if there is no match. This often saves the cost of the much more involved regular expression. For libvirt, this decreases the cost from 1.44s to 1.02s. 2016-07-26 Ján Tomko maint.mk: speed up sc_po_check sc_po_check would skip files based on their names, or on the existence of files with derived names. Rewrite it to use perl instead of shell to make the check faster. * top/maint.mk (perl_translatable_files_list_): Define. (sc_po_check): Use it. 2016-07-30 Ján Tomko maint.mk: speed up require_config_h_first Instead of spawning three processes per file, rewrite the check in perl and run it once for all the files. * top/maint.mk (perl_config_h_first_): Define. (sc_require_config_h_first): Use it in place of shell code. 2016-07-26 Ján Tomko maint.mk: speed up sc_po_check sc_po_check would skip files based on their names, or on the existence of files with derived names. Rewrite it to use perl instead of shell to make the check faster. * top/maint.mk (perl_translatable_files_list_): Define. (sc_po_check): Use it. 2016-07-15 Paul Eggert obstack: pacify GCC 6 with -Wnull-dereference Problem reported by Assaf Gordon in: http://lists.gnu.org/r/bug-gnulib/2016-07/msg00028.html * lib/obstack.c, lib/obstack.h (obstack_alloc_failed_handler): Declare with __attribute_noreturn__. * lib/obstack.h (__attribute_noreturn__): New macro. 2016-07-13 Eric Blake doc: mention glibc, OS X, Cygwin [S]SIZE_MAX buglet * doc/posix-headers/stdint.texi (stdint.h): Document the bugs. * doc/posix-headers/limits.texi (limits.h): Document the bugs. 2016-07-13 Paul Eggert doc: mention glibc SSIZE_MAX buglet * doc/posix-headers/limits.texi (limits.h): Document the bug. 2016-07-04 Martin Kletzander printf-posix: Fix mingw build Commit 54615b95ff238e235e806855efc46a9abad09f2e changed the regular expression for detecting C symbol prefixes but forgot to qoute square brackets in the command line arguments for grep. That way when building with mingw the condition was false although it ought to be true instead. In particular scenarios this led to the following compile error: Cannot export rpl_printf: symbol not found Cannot export rpl_scanf: symbol not found collect2: error: ld returned 1 exit status Fix this by properly quoting square brackets. 2016-07-03 Paul Eggert mktime: call tzset as per POSIX Problem reported by Ludovic Courtès in: http://lists.gnu.org/r/bug-gnulib/2016-06/msg00068.html * lib/mktime.c (mktime) [!_LIBC && HAVE_TZSET]: Call tzset. * m4/mktime.m4 (gl_FUNC_MKTIME): Check for tzset. 2016-06-26 Pádraig Brady fts: handle readdir() errors * lib/fts.c (fts_build): readdir(3) returns NULL when finished, but also upon error when it will also set errno. Therefore flag the error case from readdir(). We treat the case where no items are read the same as if the dir can't be accessed, i.e. by setting fts_errno to FTS_DNR. 2016-06-24 Paul Eggert intprops: port better to GCC 7 GCC 7 __builtin_add_overflow supports a new usage form, where the last argument is a null pointer, and which merely returns 1 if an overflow would occur. This is a constant expression if all arguments are constants, and should generate faster code when code needs to be generated. * lib/intprops.h (_GL_HAS_BUILTIN_OVERFLOW_WITH_NULL): New macro. (_GL_ADD_OVERFLOW, _GL_SUBTRACT_OVERFLOW, _GL_MULTIPLY_OVERFLOW): Use builtin operations if available. (INT_NEGATE_OVERFLOW): Prefer INT_SUBTRACT_OVERFLOW if builtin operations are available, as it's almost surely faster. 2016-06-23 Paul Eggert intprops-test: port to GCC 6 * tests/test-intprops.c: Ignore -Woverflow if any GCC version, since the bug is not fixed in GCC 6.1. 2016-06-13 Paul Eggert xalloc-oversized: port to GCC 7; fewer warnings GCC 7 will have a better way to deal with integer overflow. Plus, fix a warnings problem reported by Tim Ruehsen in: http://lists.gnu.org/r/bug-gnulib/2016-06/msg00022.html * lib/xalloc-oversized.h (__xalloc_oversized): New macro. (xalloc_oversized): Use plain __builtin_mul_overflow if GCC 7 or later. For GCC 5, use __xalloc_oversized if both args are constants, or if pedantic. 2016-06-08 Paul Eggert regex: port to Sun C Reported by Daiki Ueno. * lib/regcomp.c (regcomp, regerror): Use _Restrict_, not __restrict, in prototype. This fixes a problem I introduced in the 2016-02-19 merge from glibc. 2016-05-31 Paul Eggert stdbool: Restore __bool_true_false_are_defined check * m4/stdbool.m4 (AC_CHECK_HEADER_STDBOOL): __bool_true_false_are_defined is still defined, even with C++11. 2016-05-31 David Seifert (tiny change) stdbool: Port AC_CHECK_HEADER_STDBOOL to C++11 * m4/stdbool.m4 (AC_CHECK_HEADER_STDBOOL): Port to C++11. 2016-05-30 Paul Eggert Use GCC_LINT, not lint FreeBSD and Cygwin #define _Noreturn to empty if 'lint' is defined. Problem reported by Ken Brown in: http://bugs.gnu.org/23640 * doc/posix-headers/stdnoreturn.texi (stdnoreturn.h): Document problem with lint and _Noreturn. * lib/diffseq.h (IF_LINT, IF_LINT2): * lib/fts.c (sccsid): * lib/getndelim2.c (IF_LINT): * lib/gl_anylinked_list2.h (gl_linked_iterator) (gl_linked_iterator_from_to): * lib/gl_anytree_list2.h (gl_tree_iterator) (gl_tree_iterator_from_to): * lib/gl_anytree_oset.h (gl_tree_iterator): * lib/gl_array_list.c (gl_array_iterator) (gl_array_iterator_from_to): * lib/gl_array_oset.c (gl_array_iterator): * lib/gl_carray_list.c (gl_carray_iterator) (gl_carray_iterator_from_to): * lib/idcache.c: * lib/inet_ntop.c (IF_LINT): * lib/regcomp.c (build_charclass_op, create_tree): * lib/regex_internal.c (re_acquire_state) (re_acquire_state_context): * lib/trigl.c (rcsid): * lib/trim.c (IF_LINT): * lib/vasnprintf.c (IF_LINT): * lib/verify.h (assume): Treat GCC_LINT like lint. 2016-05-29 Bruno Haible secure_getenv: Port to many more platforms. * m4/secure_getenv.m4 (gl_PREREQ_SECURE_GETENV): Also check for get*id functions. * lib/secure_getenv.c (secure_getenv): Add alternate implementations for non-BSD Unix platforms and for native Windows. * doc/glibc-functions/secure_getenv.texi: Remove known issue. Prompted by a request from Nikos Mavrogiannopoulos. 2016-05-27 Eric Blake canonicalize: Fix broken probe for realpath. * m4/canonicalize.m4 (gl_FUNC_REALPATH_WORKS): Fix regression in logic introduced in 54615b95. 2016-05-26 Eric Blake unsetenv: relax to LGPLv2+ * modules/unsetenv (License): Match setenv license. 2016-05-20 Ludovic Courtès gendocs.sh: Set default TOP_NODE_UP_URL in HTML output. Suggested by Gavin Smith . Reported by myglc2 in . * build-aux/gendocs.sh (MANUAL_TITLE, PACKAGE, EMAIL) (commonarg, dirargs, dirs, infoarg, generate_ascii) (generate_html, generate_info, generate_tex, outdir) (source_extra, split, srcfile, texarg): Move above 'version'. (htmlarg): Likewise, and add "-c TOP_NODE_UP_URL=/manual". 2016-05-17 Paul Eggert manywarnings: update for GCC 6.1 * m4/manywarnings.m4 (gl_MANYWARN_ALL_GCC): Add GCC 6.1 options that apply to C. * build-aux/gcc-warning.spec: Add GCC 6.1 options that do not apply to C, are obsolescent, etc. 2016-05-12 Paul Eggert glob: size_t overflow checks * lib/glob.c (__has_builtin): New macro. (size_add_wrapv, glob_use_alloca): New static functions. (glob, glob_in_dir): Check for size_t overflow in several places, and fix some size_t checks that were not quite right. glob: don't assume INT_MAX < SIZE_MAX * lib/glob.c (glob): Prefer SIZE_MAX to ~((size_t) 0), as the latter is not portable to (probably theoretical) hosts where SIZE_MAX <= INT_MAX. 2016-05-09 Bruno Haible Fix undefined behaviour in gettext.h. * lib/gettext.h (dcpgettext_expr, dcnpgettext_expr): Avoid accessing a pointer's value after the storage it points to has been freed. Reported by Michael Pyne in https://savannah.gnu.org/bugs/?47847. Spotted by Coverity. 2016-05-08 Paul Eggert git-version-gen: avoid undefined shift Problem reported by Mosè Giordano in: http://lists.gnu.org/r/bug-gnulib/2016-05/msg00012.html * build-aux/git-version-gen: Avoid undefined behavior if invoked with --prefix or --fallback but without a later argument. While we're at it, omit unnecessary quotes. 2016-05-04 Paul Eggert glob: merge glibc changes into lib/glob.c * lib/glob.c (glob_in_dir): Sync with glibc/posix/glob.c, dated 2016-05-04 12:09:35 2016 +0200. Here are the changes: 2016-05-04 CVE-2016-1234: glob: Do not copy d_name field of struct dirent [BZ #19779] 2016-04-29 glob: Simplify the interface for the GLOB_ALTDIRFUNC callback gl_readdir 2015-10-20 Convert miscellaneous function definitions to prototype style 2015-10-20 Convert 113 more function definitions to prototype style (files with assertions) 2015-06-12 Fix getlogin_r namespace (bug 18527). 2014-02-10 Use glibc_likely instead __builtin_expect. 2013-10-20 When glob pattern contains a trailing slash match only directories. Fixes bug 10278. 2013-09-04 glob: silence -Wattribute warnings 2013-06-07 Avoid use of "register" as optimization hint. 2012-09-25 Use size_t instead of int for internal variables in glob (bug 14621) 2011-07-20 Check for overflows in expressions 2011-05-28 Remove unused variable 2011-05-22 Add a few more alloca size checks 2010-03-27 Whitespace fixes 2010-03-27 Fix one more issue with the glob patch 2010-03-24 Fix glob with empty pattern 2008-05-27 Remove useless more "if" tests before "free" * modules/glob (Depends-on): Add stdint. 2016-05-01 Paul Eggert mktime: port to stricter signed overflow checking * lib/mktime.c: Omit 'pragma GCC optimize ("wrapv")'. (long_int): Require width for INT_MAX * 3 * (seconds per year), instead of merely for INT_MAX * 2. In practice platforms that do the latter also do the former. (TIME_T_MIN, TIME_T_MAX, TIME_T_MIDPOINT, SHR): Remove. (shr): New static function, replacing SHR. All uses changed. (mktime_min, mktime_max): New constants, replacing TIME_T_MIN and TIME_T_MAX. All uses changed. (ydhms_diff, guess_time_tm, ranged_convert, __mktime_internal): Use long_int, not time_t. (long_int_avg): New static function, replacing time_t_avg. All uses changed. Round toward positive infinity, as that generates slightly better code. (time_t_add_ok, time_t_int_add_ok): Remove. All uses replaced by INT_ADD_WRAPV. (guess_time_tm): Accept time, not a pointer to it. All uses changed. (convert_time): New static function. (ranged_convert): Use it (ranged_convert): Check for *T out of [mktime_min, mktime_max] range. Use simpler test for loop exit. (__mktime_internal): Store negative of guessed offset, to simplify overflow checking. Remove no-longer-needed test for small time_t overflows. mktime: speed up DEBUG_MKTIME benchmarks Call tzset just once, at the start, rather than for every test case. This lets us measure the CPU cost of mktime as opposed to that of tzset. This is relevant when TZ is not set and glibc is being used. This speeds up tests by a factor of 40 on my Fedora 23 x86-64 platform. * lib/mktime.c (main) [DEBUG_MKTIME]: Call localtime at the start, to call tzset and as a sanity check. Later on, use localtime_r instead of localtime. mktime: resurrect DEBUG_MKTIME testing * lib/mktime.c [DEBUG_MKTIME]: Do not include . Include , for strcmp. mktime: simplify DEBUG_MKTIME * lib/mktime.c (DEBUG_MKTIME): Define to 0 if not defined. Simplify later usage accordingly. Port mktime_internal offset to unsigned time_t This avoids some assumptions about wraparound arithmetic on signed integer overflow. * lib/mktime-internal.h (mktime_offset_t): New type. (mktime_internal): Use it in decl. * lib/mktime.c, lib/timegm.c (mktime_offset_t) [_LIBC]: New type. * lib/mktime.c (__mktime_internal, localtime_offset): * lib/timegm.c (timegm): Use it. * m4/mktime.m4 (gl_TIME_T_IS_SIGNED): New macro. (gl_FUNC_MKTIME): Require it. 2016-04-27 Paul Eggert xstrtol: prohibit monstrosities like "1bB" Problem reported by Young Mo Kang in: http://bugs.gnu.org/23388 * lib/xstrtol.c (__xstrtol): Allow trailing second suffixes like "B" only if the first suffix needs a base. * tests/test-xstrtol.sh: Test this. 2016-04-21 Pádraig Brady xstrtod: reinstate setting of *result upon ERANGE * lib/xstrtod.c (XSTRTOD): The user may decide to use the returned limits upon ERANGE, so allow and document that. 2016-04-20 Tino Calancha (tiny change) xstrtod: modify *result only if no errors * lib/xstrtod.c (XSTRTOD). 2016-04-19 Paul Eggert btowc: document problems in C locale * doc/posix-functions/btowc.texi (btowc): Mention incompatibility with mbrtowc. See: http://bugs.gnu.org/23269#32 2016-04-13 Paul Eggert mktime: improve integer overflow checking * lib/mktime.c: Include stdbool.h, intprops.h, verify.h. (WRAPV): Remove; no longer needed. (verify): Remove. Replace all uses with call to verify.h 'verify'. (TYPE_IS_INTEGER, TYPE_SIGNED, TYPE_MINIMUM, TYPE_MAXIMUM): Remove. Use intprops.h defns instead. (leapyear, isdst_differ, time_t_add_ok, time_t_int_ok): Use bool for Boolean, for clarity. (time_t_add_ok, time_t_int_add_ok): Use INT_ADD_WRAPV to detect integer overflow. * modules/mktime (Depends-on): Add intprops, stdbool, verify. intprops: check two's complement assumption Suggested by Eric Blake in: http://lists.gnu.org/r/bug-gnulib/2016-04/msg00016.html * lib/intprops.h: Include . Verify that signed char, short, int, long, and (if available) long long are two's complement. * modules/intprops (Depends-on): Add 'verify'. intprops, mktime, strtol: assume two's complement These macros were not portable to every conforming C11 ones' complement platform. It's not worth the hassle of porting to some platforms that use ones' complement or signed magnitude, as such platforms are almost purely theoretical nowadays and porting even to some of them makes the code harder to review for little practical benefit. Problem reported by Florian Weimer in: https://sourceware.org/ml/libc-alpha/2016-04/msg00295.html * lib/intprops.h (TYPE_TWOS_COMPLEMENT, TYPE_ONES_COMPLEMENT) (TYPE_SIGNED_MAGNITUDE, _GL_INT_TWOS_COMPLEMENT): * lib/mktime.c (TYPE_TWOS_COMPLEMENT): * lib/strtol.c (TYPE_TWOS_COMPLEMENT, TYPE_ONES_COMPLEMENT) (TYPE_SIGNED_MAGNITUDE): Remove. All uses rewritten to assume two's complement, which is all we can reasonably test nowadays anyway. * top/maint.mk (_intprops_names): Remove the removed macros. 2016-04-11 Paul Eggert stdint: port to strict C11 left shift * lib/stdint.in.h (_STDINT_MIN, _STDINT_MAX): Pacify clang -Wshift-negative-value, which should be an issue only on clang setups where stdint.h does not conform to C11 or to C++11. Problem reported by Philipp Stephani in: http://bugs.gnu.org/23261 2016-04-09 Paul Eggert mbrtowc: work around glibc bug#19932 Fix mbrtowc so that it never returns -1 in the C locale, as this conflicts with a future version of POSIX http://austingroupbugs.net/view.php?id=663#c2738 and causes problems with GNU grep: http://bugs.gnu.org/23234 See glibc bug 19932: https://sourceware.org/bugzilla/show_bug.cgi?id=19932 * doc/posix-functions/mbrlen.texi (mbrlen): * doc/posix-functions/mbrtowc.texi (mbrtowc): Document the glibc bug. * lib/mbrtowc.c [C_LOCALE_MAYBE_EILSEQ]: Include hard-locale.h, locale.h. (rpl_mbrtowc): Work around the C_LOCALE_MAYBE_EILSEQ bug, if the bug is possible. * m4/mbrtowc.m4 (gl_MBRTOWC_C_LOCALE): New macro. (gl_FUNC_MBRTOWC): Use it, and define C_LOCALE_MAYBE_EILSEQ as needed. * modules/hard-locale (License): Now LGPLv2+, for mbrtowc. * modules/mbrtowc (Depends-on): Add hard-locale. * modules/mbrtowc-tests (Files, TESTS): Add tests/test-mbrtowc5.sh. * tests/test-mbrtowc.c (main): Test for bug fix if arg is '5'. * tests/test-mbrtowc5.sh: New file. 2016-04-03 Pedro Alves stdint: detect good enough pre-C++11 stdint.h in C++ mode When gnulib is configured in C++ mode for a system with a working C99 implementation of stdint.h that predates C++11, gnulib ends up substituting stdint.h anyway. This works on most targets, but on e.g., 64-bit MinGW, it doesn't, as gnulib's substitute assumes LP64, while MinGW is LLP64. Instead of trying to detect the right types, detect good-enough-pre-C++11 stdint.h and in such case define __STDC_CONSTANT_MACROS/__STDC_LIMIT_MACROS in config.h. * m4/stdint.m4 (gl_STDINT_H): Always define __STDC_CONSTANT_MACROS / __STDC_LIMIT_MACROS while checking whether the system stdint.h conforms to C99. If it does, check whether it hides symbols behind the __STDC_{CONSTANT|LIMIT}_MACROS macros. Then if it does, define those macros in config.h. 2016-04-03 Paul Eggert argp: merge changes from glibc Among other things, this should fix problems found by a Coverity scan and reported by Andrei Borzenkov: http://lists.gnu.org/r/bug-gnulib/2016-01/msg00015.html http://lists.gnu.org/r/bug-gnulib/2016-01/msg00016.html * lib/argp-ba.c, lib/argp-fmtstream.c, lib/argp-fmtstream.h: * lib/argp-fs-xinl.c, lib/argp-help.c, lib/argp-namefrob.h: * lib/argp-parse.c, lib/argp-pv.c, lib/argp-pvh.c, lib/argp-xinl.c: * lib/argp.h: Merge changes from glibc. * tests/test-argp-2.sh: Adjust to match new behavior. 2016-04-01 Paul Eggert stddef: support configuring with g++ Problem reported by Ángel González in: http://lists.gnu.org/r/bug-gnulib/2016-04/msg00003.html * lib/stddef.in.h (_GL_STDDEF_ALIGNAS, max_align_t): Do not define if _GCC_MAX_ALIGN_T is defined. 2016-03-25 Paul Eggert test-framework-sh: minor cleanups * tests/init.sh (testdir_prefix_): Output a trailing newline, since strictly speaking POSIX requires this. (setup_): Do not use the variable 'fail', as that makes the trace output harder to read ('fail' is typically used by tests to mean the test failed). Treat // portably. Check that new directory is not merely a sibling of the tmp dir. Avoid unnecessary invocation of tr. test-framework-sh: revert port to NetBSD 7.0 It was a false alarm; I misinterpreted Assaf Gordon's report. * tests/init.sh (testdir_prefix_, pfx_, template_length_): Restore. (test_dir_): Adjust to mktempd_ change. (mktempd_): Restore 2nd arg. Use -t again. (base_template_, template_, nx_): Resurrect old code. Port better to Alpine Linux Its diff implementation does not support -c, but does support -U3. Problem reported by Assaf Gordon in: http://bugs.gnu.org/23107#13 * tests/init.sh (diff_opt_): New var. (compare_): Prefer diff -U3 to diff -c to plain diff. 2016-03-24 Paul Eggert test-framework-sh: port to NetBSD 7.0 Problem reported by Assaf Gordon in: http://bugs.gnu.org/23107#13 * tests/init.sh (testdir_prefix_, pfx_, template_length_): Remove. All uses removed. (test_dir_): Adjust to mktempd_ change. (mktempd_): Omit 2nd arg. Stop using -t, as it is not portable. (base_template_, template_, nx_): Simplify by hardcoding. 2016-03-22 Paul Eggert gitlog-to-changelog: suppress ignored chatter * build-aux/gitlog-to-changelog: Do not warn about skipping an SHA if it would have been ignored anyway. 2016-03-22 Geert Janssens setlocale: add "sv" to Windows language table * lib/setlocale.c (language_table) [W32]: Add "sv". Reported in . 2016-03-21 Paul Eggert sys_select: port to new Cygwin Problem reported by Ken Brown in: https://lists.gnu.org/r/bug-gnulib/2016-03/msg00054.html * lib/sys_select.in.h [__CYGWIN__]: Avoid "unknown type name" diagnostics. 2016-03-17 Jim Meyering test-userspec.c: do not trigger gcc's new -Wmisleading-indentation * tests/test-userspec.c (main): Remove unnecessary braces and fix misleading indentation.

Problem reported by Assaf Gordon. (test_locale_name_thread): Free saved names after use, to pacify gcc -fsanitize=address. 2016-03-08 Paul Eggert intprops: make .h file license match module * lib/intprops.h: Change the license wording to match glibc format. This is what is in modules/intprops anyway. See: https://sourceware.org/bugzilla/show_bug.cgi?id=19738#c8 2016-03-08 Eric Blake acl: fix missing return on Cygwin * lib/set-permissions.c (set_acls) [HAVE_FACL && GETACL]: Don't fall off end of function. Fixes http://bugs.gnu.org/22949 2016-03-05 Bruno Haible extern-inline: port to PGI CC * m4/extern-inline.m4 (gl_EXTERN_INLINE): For PGI CC, don't use the keyword 'inline'. Reported by Adam James Stewart in: http://lists.gnu.org/r/bug-gnulib/2016-03/msg00006.html 2016-02-20 Paul Eggert signbit: port back to pre-C++11 GCC * lib/math.in.h (signbit): Do previous change only if __cplusplus < 201103. See Jonathan Wakely in: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/message/UY3VX3W7XEXYTUKHG5BALU4ACUD7ZLGE/ 2016-02-19 Kamil Dudka mountlist: recognize autofs-mounted remote file systems, too Originally reported at: https://bugzilla.redhat.com/1309247 * lib/mountlist.c (ME_REMOTE): Return true if a file system is named "-hosts" because it is used by autofs to mount remote file systems. 2016-02-19 Paul Eggert signbit: port to C++ with GCC 6 * lib/math.in.h (signbit) [__cplusplus]: Do not replace with GCC builtin. Reported by Orion Poplawski in: http://lists.gnu.org/r/bug-gnulib/2016-02/msg00005.html * lib/regex_internal.h (IDX_MAX) [_REGEX_LARGE_OFFSETS]: Now SSIZE_MAX. regex: make it closer to libc Make Idx a signed type, rather than possibly unsigned. The unsignedness was not really buying us anything, since the code overflows for other reasons before getting to PTRDIFF_MAX. Making it signed allows us to use -1 and -2 with abandon, like libc does, thus lessening the number of differences between gnulib and libc. Also, it should help avoid gratuitous warnings like the one reported by Nelson H. F. Beebe in: http://bugs.gnu.org/22702 * lib/regex.h (__re_idx_t): Remove.

Use internal_function for internal functions. 2016-02-10 Paul Eggert stdalign: port to older HP and IBM cc * lib/stdalign.in.h (_Alignas): Port better to older HP and IBM C compilers, by checking their version numbers. These version numbers appear in MariaDB and in Qt code that dates way back and that conditiionally uses the 'aligned' attribute. 2016-02-09 Paul Eggert stdalign: port to clang 3.7.0 Problem reported by Herbert J. Skuhra in: http://lists.gnu.org/r/emacs-devel/2016-02/msg00476.html * lib/stdalign.in.h (alignas): Fix typo that prevented 'alignas' from being defined on clang 3.7.0, which has a buggy stdalign.h.

Otherwise, that .Tpo file would cause a failed "make distcheck" at least for grep. 2016-02-02 Paul Eggert std-gnu11: new module This makes it easier for applications to prefer C11 and C++11 to older variants, when compiling C and C++ code. Unlike most m4/*.m4 files, m4/std-gnu11.m4 is GPLed, as it copies a nontrivial chunk of GPLed Autoconf source code. * COPYING: Mention the m4/*.m4 copyright situation. * MODULES.html.sh (std-gnu11): New module. * m4/std-gnu11.m4, modules/std-gnu11: New files. 2016-01-25 Paul Eggert get-permissions, strftime: fix grammar in comments * lib/get-permissions.c, lib/strftime.c: Merge into the comments some grammar fixes Alan Mackenzie made to GNU Emacs. 2016-01-25 Daiki Ueno gettext: mark as obsolete Suggested by Paul Eggert in: https://lists.gnu.org/r/bug-gnulib/2016-01/msg00101.html * modules/gettext (Status): Mark as obsolete.

Reported by Pádraig Brady. 2015-11-03 Pádraig Brady quotearg: constify get_quoting_style parameters * lib/quotearg.h (get_quoting_style): Mark parameter as const. * lib/quotearg.c (get_quoting_style): Likewise. 2015-11-02 Pádraig Brady quotearg: add support for $'' shell escaping * lib/quotearg.h: Add "shell-escape" and "shell-escape-always" items and descriptions. * lib/quotearg.c (quotearg_buffer_restyled): Add support for the above types by quoting like "shell", but using $'...' syntax for non printable characters, which should provide unambiguous printable output for any input. * tests/test-quotearg-simple.c: Update accordingly. 2015-11-02 Pádraig Brady maint: use a more standard return from mbrtowc test * m4/mbrtowc.m4 (gl_MBRTOWC_EMPTY_INPUT): Don't return 1 from the test program as this is non standard and often indicates an unhandled case in the test program. * m4/mbrlen.m4 (gl_MBRLEN_EMPTY_INPUT): Likewise. 2015-10-30 Paul Eggert intprops: add WRAPV and const flavors for GCC 5 If available, use GCC 5's builtin functions for efficient integer overflow checking. Also, add macros like INT_ADD_WRAPV efficently and safely compute the low-order bits of the correct answer. A downside of these efficient functions is that they cannot be used in constant expressions, so add macros like INT_CONST_ADD_OVERFLOW and INT_CONST_ADD_WRAPV that can be used even in constant expressions. * NEWS: Document the incompatible changes to INT_ADD_OVERFLOW etc. * doc/intprops.texi (Integer Properties, Integer Type Overflow): Document the changes. (Wraparound Arithmetic): New section. (Integer Range Overflow): Put this subsection last, since it's least useful. * lib/intprops.h (INT_CONST_ADD_OVERFLOW) (INT_CONST_SUBTRACT_OVERFLOW, INT_CONST_MULTIPLY_OVERFLOW): New macros, with the meaning that INT_ADD_OVERFLOW etc. used to have. (INT_CONST_ADD_WRAPV, INT_CONST_SUBTRACT_WRAPV) (INT_NEGATE_WRAPV, INT_CONST_MULTIPLY_WRAPV, INT_DIVIDE_WRAPV) (INT_REMAINDER_WRAPV, _GL_INT_OP_WRAPV, _GL_EXPR_CAST) (_GL_INT_OP_WRAPV_LONGISH, INT_ADD_WRAPV, INT_SUBTRACT_WRAPV) (INT_MULTIPLY_WRAPV, _GL_OP_OVERFLOW, _GL_OP_WRAPV, _GL_OP_WRAPV_GENSYM): New macros.

(main, CHECK_BINOP, CHECK_UNOP, CHECK_SUM, CHECK_PRODUCT) (CHECK_QUOTIENT, CHECK_REMAINDER): Test WRAPV and CONST flavors (when available) too. 2015-10-30 Pádraig Brady doc: use extended timezone format in iso-8601 example * doc/parse-datetime.texi: The standard states that extended format is to be used consistently throughout. Note that lib/parse-datetime.y can handle either tz format. 2015-10-25 Paul Eggert stdalign: port to Sun C 5.9 * doc/posix-headers/stdalign.texi: Document this. * lib/stdalign.in.h (_Alignas): Sun C 5.9 also supports __attribute__ ((__aligned__ (...))). 2015-10-20 Paul Eggert time_rz: fix comment about tzalloc * lib/time_rz.c (tzalloc): Fix comment. 2015-10-18 Paul Eggert stdalign: work around pre-4.9 GCC x86 bug * lib/stdalign.in.h (_Alignof): Work around bug in pre-4.9 GCC on x86, when -std=gnu11 is used. Problem reported by Jim Meyering in: http://lists.gnu.org/r/bug-gnulib/2015-10/msg00038.html 2015-10-18 Pádraig Brady maint.mk: sc_tight_scope: remove extraneous expressions * top/maint.mk (tight_scope): This is not really required since commit 3ef58f46 as sed_wrap ensures we don't get an empty expression that matches all nm entries. But it does remove extraneous entries that may be confusing or cause issue in future maintenance. 2015-10-18 Paul Eggert time_rz: return NULL if localtime_r fails * lib/time_rz.c (localtime_rz): Return NULL if localtime_r fails, while still attempting to pacify bleeding-edge GCC. fts: port to C11 alignof * doc/posix-headers/stdalign.texi (stdalign.h): Document the C11 restriction. * lib/fts.c: Include stddef.h, for max_align_t. (fts_alloc): Align using max_align_t, not FTSENT. * modules/fts (Depends-on): Add stddef. 2015-10-18 Jim Meyering time_rz: avoid warning from bleeding-edge gcc's -Wnonnull Compiling with gcc version 6.0.0 20151017 (experimental) (GCC), I would see this: lib/time_rz.c: In function 'localtime_rz': lib/time_rz.c:292:15: error: nonnull argument 'tm' compared to NULL \ [-Werror=nonnull] if (tm && !save_abbr (tz, tm)) ^ That was complaining about "tm" because it is a parameter that was declared with the __nonnull__ attribute. * lib/time_rz.c (localtime_rz): Don't bother setting "tm" to the result of localtime_r. 2015-10-17 Jim Meyering maint.mk: _gl_TS_function_match: fix "extern" name extracting regexp * top/maint.mk (_gl_TS_function_match): This heuristic extern-function- name-extraction regexp mistakenly used \S+, and would mistakenly extract "*F" from "extern int *F()" rather than the desired "F". Use \w+ instead. 2015-10-17 Jim Meyering maint.mk: sc_tight_scope: factor and support OS X * top/maint.mk (_gl_tight_scope): Address three issues: - factor out four instances of code that wraps a string in "^...$" - allow nm-reported symbol names to have an optional leading "_" - add "main" to the list of ignored variable names, because on os x, "main" has nm-reported type "S" in the variable-checking section. 2015-10-16 Dmitry Smirnov safe-alloc-tests: fix typo in license header * tests/test-safe-alloc.c: Mention LGPL 2.1, not 3.1 2015-10-15 Simon Reinhardt copy-file: fix mem leak in error case * lib/copy-file.c (qcopy_file_preserving): Free the 32KiB buffer upon error opening or performing I/O to the src and dest files. 2015-10-15 Mike Frysinger localename: control langinfo.h inclusion This header is only used to work around buggy behavior in old versions of glibc, so do not include it all the time. Otherwise we get build failures on systems that do not provide langinfo.h. * lib/localename.c: Wrap langinfo.h include with same ifdefs used in the source later on. The patch was originally submitted to gettext as: https://lists.gnu.org/r/bug-gettext/2015-10/msg00011.html 2015-10-13 Paul Eggert binary-io, math, pthread, sys_socket, u64, unistd: port to strict C * lib/binary-io.c, lib/math.c, lib/pthread.c, lib/sys_socket.c: * lib/u64.c, lib/unistd.c: Append 'typedef int dummy;', to pacify compilers that are picky about empty translation units. 2015-10-12 Pino Toscano accept4-tests: fix to avoid non portable flags * tests/test-accept4.c (main): Pass only SOCK_* flags to accept4(), as they are the only documented ones, and passing others may trigger EINVAL (seen on FreeBSD 10.1-RELEASE). * doc/glibc-functions/accept4.texi: Mention that we don't provide the SOCK_CLOEXEC or SOCK_NONBLOCK defines. 2015-10-06 Pavel Raiskup gnulib-tool: fix tests of 'extensions' module This complements f8fe25fab60e3c687a124 commit. * gnulib-tool (func_emit_pre_early_macros): New function, it wraps emitting of initial gl_EARLY macros. (func_import, func_create_testdir): All dumps of gl_PROG_AR_RANLIB replaced with func_emit_pre_early_macros call. 2015-10-06 Paul Eggert unicase/locale-language: fix typo in utf-8 cookie * lib/unicase/locale-languages.gperf: Fix gperf input file format. Problem reported by Zbigniew Jędrzejewski-Szmek. 2015-10-02 Paul Eggert xalloc: do not worry about GCC 5 warning on 32 bit * lib/xalloc.h: Revert previous change. I found a better way to fix this in coreutils. 2015-10-02 Pádraig Brady xalloc: avoid GCC 5.1 warning on 32 bit * lib/xalloc.h: Disable -Wstrict-overflow for uses of xalloc_oversized(), which was seen to give this warning on GCC 5.1 on 32 bit: "assuming signed overflow does not occur when simplifying conditional". 2015-10-02 Daiki Ueno uniname/uniname-tests: avoid compiler warnings * tests/uniname/test-uninames.c (fill_names, fill_aliases): Remove unused local variables. (test_alias_lookup): Fix alias name display in failure cases. 2015-09-26 Paul Eggert c-ctype: do not worry about EBCDIC + char signed Drop support for EBCDIC with char being signed, as this breaks too many programs. Problem reported by Ben Pfaff in: http://lists.gnu.org/r/bug-gnulib/2015-09/msg00053.html * lib/c-ctype.h: Verify that we are not using EBCDIC with char being signed. (_C_CTYPE_LOWER_A_THRU_F_N): New macro. (_C_CTYPE_LOWER_N, _C_CTYPE_A_THRU_F): Use it. (_C_CTYPE_DIGIT, _C_CTYPE_LOWER, _C_CTYPE_PUNCT, _C_CTYPE_UPPER): (c_isascii, c_isgraph, c_isprint, c_ispunct, c_tolower, c_toupper): * tests/test-c-ctype.c (test_all): Simplify by assuming standard char values cannot be negative. * tests/test-c-ctype.c (NCHARS, to_char): Remove; all uses removed. 2015-09-25 Paul Eggert c-ctype: port better to z/OS EBCDIC Problems reported by Daniel Richard G. in: http://lists.gnu.org/r/bug-gnulib/2015-09/msg00050.html * lib/c-ctype.h (_C_CTYPE_CNTRL): Rewrite in terms of the C standard escapes and _C_CTYPE_OTHER_CNTRL. (_C_CTYPE_OTHER_CNTRL): New macro. * tests/test-c-ctype.c (test_all): Test from CHAR_MIN, not from SCHAR_MIN, as the functions are defined only from values promoted from char or from unsigned char, not necessarily from signed char. 2015-09-25 Pavel Raiskup gnulib-common.m4: fix gl_PROG_AR_RANLIB/AM_PROG_AR clash The gl_PROG_AR_RANLIB (it is always called by gl_EARLY) sets AR and ARFLAGS variables. Doing this unconditionally could break later Automake's AM_PROG_AR invocation (at least it's AC_CHECK_TOOLS call to detect correct 'ar' binary). Original purpose of the gl_PROG_AR_RANLIB was only to handle the Amsterdam Compiler Kit, so make the previous code to have effects only on ACK, and rather automatically call the Automake's AM_PROG_AR as soon as possible to decide other cases. References: http://lists.gnu.org/r/bug-gnulib/2015-07/msg00001.html * m4/gnulib-common.m4 (gl_PROG_AR_RANLIB): AC_BEFORE AM_PROG_AR. Set the AR/ARFLAGS to ACK defaults OR call AM_PROG_AR. If neither is possible, keep setting AR/ARFLAGS to reasonable defaults. * gnulib-tool (func_import): Put the gl_USE_SYSTEM_EXTENSIONS right before gl_PROG_AR_RANLIB into gnulib-comp.m4 (if the 'extensions' module is used. * modules/extensions (configure.ac-early): Remove as this snippet is added to gnulib-comp.m4 earlier anyway. 2015-09-25 Paul Eggert sockets: MS Windows initalization fixes Problem reported by Test User in: http://lists.gnu.org/r/help-shishi/2015-09/msg00001.html * lib/sockets.h (SOCKETS_1_0, SOCKETS_2_0, SOCKETS_2_1): Correct the endianness. * lib/sockets.c (gl_sockets_startup): Return 2 on any version number mismatch, not just on <. Cleanup before any such failure. 2015-09-25 Mats Erik Andersson gc: fix detection of installed libgcrypt version * m4/gc.m4: Use AM_PATH_LIBCRYPT to test for libcrypt versions at least as recent as 1.4.4. The previously used macro is not available now, since modules were removed in version 1.6.0. 2015-09-25 Paul Eggert c-ctype: rewrite to use inline functions This simplifies maintenance, since it makes for just one implementation of each function, letting the compiler have the fun of optimization. In practice this works well nowadays with GCC. E.g., c_isascii might need only three instructions even though the source code lists every ASCII character individually in a large switch statement. Also, fix some z/OS porting bugs reported by Daniel Richard G. in: http://lists.gnu.org/r/bug-gnulib/2015-09/msg00037.html * NEWS: Document the API change. * lib/c-ctype.c: Drastically simplify, since this now just expands inline functions. * lib/c-ctype.h: Use _GL_INLINE_HEADER_BEGIN, _GL_INLINE_HEADER_END. (C_CTYPE_INLINE): New macro. (C_CTYPE_CONSECUTIVE_DIGITS, C_CTYPE_CONSECUTIVE_LOWERCASE) (C_CTYPE_CONSECUTIVE_UPPERCASE): Remove. Verify that either ASCII or EBCDIC is being used. (_C_CTYPE_SIGNED_EBCDIC, _C_CTYPE_CNTRL, _C_CTYPE_A_THRU_F_N) (_C_CTYPE_DIGIT_N, _C_CTYPE_LOWER_N, _C_CTYPE_UPPER_N) (_C_CTYPE_CASES, _C_CTYPE_A_THRU_F, _C_CTYPE_DIGIT, _C_CTYPE_LOWER) (_C_CTYPE_UPPER, _C_CTYPE_PUNCT_PLAIN): New private macros. (_C_CTYPE_CNTRL): In EBCDIC, '\x07' is a control, not '\xff'. (c_isalnum, c_isalpha, c_isascii, c_isblank, c_iscntrl, c_isdigit) (c_isgraph, c_islower, c_isprint, c_ispunct, c_isspace, c_isupper) (c_isxdigit, c_tolower, c_toupper): Now inline functions. (c_tolower, c_toupper): When converting, return the unsigned char, as that is what z/OS does. * lib/c-strcaseeq.h (CASEEQ): Simplify in the light of the removal of some c-ctype.h macros. * modules/c-ctype (Depends-on): Add extern-inline; remove verify. * tests/test-c-ctype.c (test_all): Fix test for c_toupper and c_tolower promotion to be compatible with z/OS. 2015-09-24 Pavel Raiskup gitlog-to-changelog: trim only trailing whitespaces This is fix for --format regression introduced by commit 2b93079a5d1baa4d; it caused that --format='%s%n%n%b%n' (see the doubled %n string) had no effect anymore. This format specification has been used e.g. by GNU paxuitils (commit edfd8bcc3). * build-aux/gitlog-to-changelog (main): Stop squashing multiple newlines in commmit messages. 2015-09-23 Paul Eggert Test that c_iscntrl agrees with iscntrl, etc. Suggested by Daniel Richard G. in: http://lists.gnu.org/r/bug-gnulib/2015-09/msg00034.html * modules/c-ctype-tests (Depends-on): Add ctype. * tests/test-c-ctype.c: Include . (NCHARS): New constant. (test_agree_with_C_locale): New function. (main): Use it. (test_all): Use named constants. c-ctype: improve c_isascii testing * tests/test-c-ctype.c (test_all): Port c_isascii test to EBCDIC. Add a test to count the number of ASCII characters. 2015-09-22 Paul Eggert savewd: remove SAVEWD_CHDIR_READABLE It was problematic in the light of file systems that ignore umask. Problem reported by Sebastian Unger in: http://bugs.gnu.org/21534 * NEWS: Document this. * lib/mkancesdirs.c (mkancesdirs): MAKE_DIR now returns 0 if successful, -1 (setting errno) on failure, rather than something more complicated than that. * lib/mkdir-p.c (make_dir_parents): Do not use SAVEWD_CHDIR_READABLE. * lib/savewd.c (savewd_chdir): Remove support for SAVEWD_CHDIR_READABLE. * lib/savewd.h (SAVEWD_CHDIR_READABLE): Remove. c-ctype: port better to EBCDIC Problems reported by Daniel Richard G. in http://lists.gnu.org/r/bug-gnulib/2015-09/msg00020.html * lib/c-ctype.c: Include , for CHAR_MIN and CHAR_MAX. Include "verify.h". (C_CTYPE_ASCII, C_CTYPE_CONSECUTIVE_DIGITS) (C_CTYPE_CONSECUTIVE_LOWERCASE, C_CTYPE_CONSECUTIVE_UPPERCASE): Define as enum constants with value false, if not defined, so that code can use 'if' instead of 'ifdef'. Using 'if' helps make the code more portable, as both branches of the 'if' are compiled on all platforms. (C_CTYPE_EBCDIC): New constant. Verify that the character set is either ASCII or EBCDIC. (to_char): New static function. (c_isascii, c_iscntrl): Assume standard control-character assignments for EBCDIC. (c_isalnum, c_isalpha, c_isdigit, c_islower, c_isgraph, c_isprint) (c_ispunct, c_isupper, c_isxdigit, c_tolower, c_toupper): Rewrite to use 'if' instead of 'ifdef'. Use to_char if non-ASCII. Prefer <= to >=. Prefer true and false to 1 and 0, for booleans. (c_iscntrl): Use 'if', not 'ifdef'. * modules/c-ctype (Depends-on): Add verify. * tests/test-c-ctype.c: Include , for CHAR_MIN (to_char): New function. (test_all): Port to EBCDIC. Add some more tests, e.g., for c_ispunct. 2015-09-21 Pádraig Brady nanosleep: fix return code for interrupted replacement * lib/nanosleep.c (nanosleep): In the replaced nanosleep, ensure that we return -1 in the case the call is interrupted by a signal, rather than the current value of 1. Diagnosed and tested by Daniel Richard G. 2015-09-19 Paul Eggert Diagnose ERE '()|\1' Problem reported by Hanno Böck in: http://bugs.gnu.org/21513 * lib/regcomp.c (parse_reg_exp): While parsing alternatives, keep track of the set of previously-completed subexpressions available before the first alternative, and restore this set just before parsing each subsequent alternative. This lets us diagnose the invalid back-reference in the ERE '()|\1'. regex: merge patches from libc 2015-09-08 Joseph Myers Move bits/libc-lock.h and bits/libc-lockP.h out of bits/ (bug 14912). * lib/regex_internal.h: Include instead of . 2015-06-09 Joseph Myers Fix regcomp wcscoll, wcscmp namespace (bug 18497). * lib/regcomp.c (build_range_exp): Call __wcscoll instead of wcscoll. * lib/regexec.c (check_node_accept_bytes): Likewise. 2015-06-05 Joseph Myers Fix regex wcrtomb namespace (bug 18496). * lib/regex_internal.c (build_wcs_upper_buffer): Call __wcrtomb instead of wcrtomb. 2015-06-05 Joseph Myers Fix regex wctype namespace (bug 18495). * lib/regcomp.c (re_compile_fastmap_iter): Call __towlower instead of towlower. * lib/regex_internal.c (build_wcs_upper_buffer): Call __iswlower instead of iswlower.

Discussed here: http://lists.gnu.org/r/bug-gnulib/2015-08/msg00010.html 2015-09-08 Dave Chiluk mountlist: add me_mntroot field on Linux machines * lib/mountlist.c (read_file_system_list): Populate me_mntroot in mount_entry so Linux machines based on /proc/self/mountinfo can distinguish between bind mounts and original mounts. In reality bind mounts aren't treated differently than mountroot=/ mounts by the kernel, but the user often wants these bind mounts distinguished. * lib/mountlist.h (struct mount_entry): Add me_mntroot element.

Fixes this error: gawk: ./build-aux/pmccabe2html:425: \ warning: escape sequence `\&' treated as plain `&' 2015-07-29 Paul Eggert time_rz: port to pedantic memcpy * lib/time_rz.c (tzalloc): Pacify pedantic memcpy implementations that reject memcpy (..., NULL, 0). 2015-07-27 Paul Eggert time_rz: port better to MinGW Don't change tzname, as this makes MinGW dump core (Bug#21020). Instead, store the tzname copy in the struct tm_zone object. Problem reported by Eli Zaretskii in: http://bugs.gnu.org/21020#48 * lib/strftime.c [!_LIBC]: * lib/time_rz.c: Include time-internal.h. * lib/strftime.c (strftime_case_) [!HAVE_TM_ZONE]: Infer the zone name from *TZ rather than from TZNAME, doable because *TZ now has a tzname_copy member. * lib/time-internal.h: New file, with contents taken from lib/time_rz.c. It's separate because strftime.c now accesses struct tm_zone members. (struct tm_zone) [HAVE_TZNAME && !HAVE_TM_ZONE]: New member tzname_copy. * lib/time_rz.c (struct tm_zone): Move to time-internal.h.

Fix reported by Eli Zaretskii in: http://bugs.gnu.org/21020#36 2015-07-25 Paul Eggert strftime: fix newly-introduced bug on Solaris * lib/strftime.c (strftime_case_): Set the local variable 'zone' consistently at the start, rather than doing some of the setup at the start and some in the %Z format spec. This is cleaner, and works better with time_rz on platforms like Solaris where struct tm lacks a tm_zone member, as when !HAVE_TM_GMTOFF %z's calls to mktime_z and localtime_rz can mess up the tzname cache. test-strftime: test for Solaris bug * modules/strftime-tests (Depends-on): Add strerror. * tests/test-strftime.c: Include .

All uses changed. (strftime_case_): Use localtime_rz and mktime_z instead of localtime_r and mktime. * modules/fprintftime (Depends-on): Add time_rz. * modules/strftime (Depends-on): Add time_rz. Remove time_r. * tests/test-strftime.c (main): Adjust to new nstrftime API. time_rz: new module * MODULES.html.sh: Add time_rz. * lib/time_rz.c, m4/time_rz.m4, modules/time_rz: New files. * lib/time.in.h (timezone_t, tzalloc, tzfree, localtime_rz, mktime_z): New decls if _GNU_SOURCE && @GNULIB_TIME_RZ@ && ! @HAVE_TIMEZONE_T@. * m4/sys_time_h.m4 (gl_HEADER_SYS_TIME_H_DEFAULTS): New var HAVE_TIMEZONE_T (default 0). * m4/time_h.m4 (gl_HEADER_TIME_H_DEFAULTS): New var GNULIB_TIME_RZ (default 0). * modules/time (time.h): Substitute the new vars. flexmember: license is now unlimited * modules/flexmember (License): Change to unlimited, since its only source file gives an unlimited license. 2015-07-15 Eric Blake maint: update copyright paper procedures * config/srclist.txt: Drop outdated files. * doc/Copyright/conditions.txt: Update to latest. * doc/Copyright/assign.changes.manual: Delete. * doc/Copyright/assign.future.manual: Likewise. * doc/Copyright/assign.manual: Likewise. * doc/Copyright/assign.translation.manual: Likewise. * doc/Copyright/disclaim.changes.manual: Likewise. * doc/Copyright/disclaim.manual: Likewise. * doc/Copyright/disclaim.program: Likewise. 2015-07-07 Daiki Ueno localename: fix link error on Illumos Illumos defines __sun, but does not have getlocalename_l nor the equivalent. This partially reverts commit 387c214. * m4/localename.m4 (gl_LOCALENAME): Check if getlocalename_l is available, as well as uselocale. * lib/localename.c [HAVE_USELOCALE && __sun]: Don't fallback to use getlocalename_l if it is not available. 2015-07-07 Daiki Ueno unistr/uN-strtok-tests: avoid a trivial leak * tests/unistr/test-u-strtok.h (test_u_strtok): Untabify. Free input and delim after the multibyte delimiter tests. 2015-07-04 Paul Eggert file-has-acl, acl-permissions: fix HP-UX typos Problem reported by John David Anglin in: http://bugs.gnu.org/20979 * lib/file-has-acl.c (file_has_acl): * lib/set-permissions.c (context_acl_from_mode) (context_aclv_from_mode, set_acls): Fix some obvious typos when HAVE_GETCL /* HP-UX */. They were introduced by the recent ACL changes. regex: match current GNU grep behavior These symbols have not matched GNU grep behavior for quite some time. Fix prompted by Balazs Kezes bug report at: http://bugs.gnu.org/20974 * lib/regex.h (RE_SYNTAX_GREP, RE_SYNTAX_EGREP): Change to match current GNU behavior. Simplify by expressing it as differences from POSIX BREs and EREs. (RE_SYNTAX_POSIX_EGREP): No longer differs from GNU behavior. 2015-07-03 Jim Meyering set-permissions.c: adjust acl_from_mode's cpp guard * lib/set-permissions.c (acl_from_mode): Guard with #ifdef directives identical to those guarding the sole use. Otherwise, on some systems, we'd get a warning about the function being defined but not used. Also, filter through cppi to correct misleading indentation of cpp directives. 2015-07-03 Pádraig Brady tests: restrict shells to those that support 'local' The local keyword is very widely supported and used in tests in coreutils and grep at least. Therefore restrict to testing with shells that support it. This mainly excludes /bin/sh on Solaris. * tests/init.sh (gl_shell_test_script_): Add a test for 'local'. 2015-07-03 Seiya Kawashima (tiny change) and Daiki Ueno unistr/uN-strtok: handle multibyte delimiters Previously, uN_strtok moved PTR to the next unit to the token end. When DELIM contained a multibyte character, the new position could be a middle of a multibyte character. * lib/unistr/u-strtok.h (FUNC): Place PTR at the next character after the token. * lib/unistr/u8-strtok.c (U_STRMBLEN): New macro. * lib/unistr/u16-strtok.c (U_STRMBLEN): New macro. * lib/unistr/u32-strtok.c (U_STRMBLEN): New macro. * modules/unistr/u8-strtok (Depends-on): Depend on unistr/u8-strmblen. * modules/unistr/u16-strtok (Depends-on): Depend on unistr/u16-strmblen. * modules/unistr/u32-strtok (Depends-on): Depend on unistr/u32-strmblen. * tests/unistr/test-u-strtok.h: New file. * tests/unistr/test-u8-strtok.c: New file. * tests/unistr/test-u16-strtok.c: New file. * tests/unistr/test-u32-strtok.c: New file. * modules/unistr/u8-strtok-tests: New file. * modules/unistr/u32-strtok-tests: New file. * modules/unistr/u16-strtok-tests: New file. 2015-07-02 Friedrich Haubensak update-copyright: fix test failure with perl >= 5.22 (trivial) * build-aux/update-copyright: Escape a literal left curly bracket, required with perl >= 5.22 2015-07-02 Daiki Ueno u{16,32}-strstr-tests: relax timeout condition On slower platforms (e.g., Solaris 10/SPARC), u{16,32}-strstr tests can take longer than 5 seconds to complete. Reported by Dagobert Michelsen in: https://lists.gnu.org/r/bug-libunistring/2015-06/msg00006.html * tests/unistr/test-u16-strstr.c (main): Increase timeout from 5 seconds to 10 seconds. * tests/unistr/test-u32-strstr.c (main): Likewise. 2015-07-01 Pavel Raiskup gnulib-common.m4: change the ARFLAGS default to 'cr' In some GNU/Linux distributions people started to compile 'ar' binary with --enable-deterministic-archives (binutils project). That, however, in combination with previous autotools long time working default AR{_,}FLAGS=cru causes warnings on such installations: ar: `u' modifier ignored since `D' is the default (see `U') * m4/gnulib-common.m4 (gl_PROG_AR_RANLIB): Set ARFLAGS='cr' if not set already. 2015-07-01 Pavel Raiskup selinux-h: avoid double free after *getfilecon() Originally reported by Ben Shelton on bug-tar: http://lists.gnu.org/r/bug-tar/2015-04/msg00009.html * lib/getfilecon.c (map_to_failure): Set the already freed '*con' pointer to NULL. Man getfilecon(3) says that any non-NULL '*con' param should be freed by freecon(3) (regardless the return value). 2015-07-01 Pavel Fedin fix pty related tests issues on Windows (trivial) * lib/grantpt.c (grantpt): grantpt.c seems to be never used on Windows, however it's still present in tests/ subdirectory of the final project. Therefore avoid it to pass `make check`. * tests/test-openpty.c (main): Windows has no PTYs and gnulib's openpty() will just return -ENOSYS, so avoid this non applicable test allowing the build to proceed. 2015-07-01 Pádraig Brady acl: fix definition of acl_from_mode on FreeBSD This was causing basic coreutils copy operations to fail with ENOTSUP or ENOENT error messages. * lib/acl-internal.h (acl_from_mode): Only define when ! defined HAVE_ACL_FROM_TEXT. That allows the version of acl_from_mode() defined in lib/set-permissions.c to be used on FreeBSD at least. * lib/set-permissions.c: Fix up comment spelling, and a redundant variable assignment; noticed in passing. 2015-06-30 Pádraig Brady readutmp: port to FreeBSD >= 9 * lib/readutmp.h: Map utmpxname() to setutxdb(). With that coreutils who(1) and pinky(1) tests pass. 2015-06-30 Paul Eggert mgetgroups: port to strict OS X The previous fix wasn't working, so use a bigger hammer (Bug#20923). * lib/mgetgroups.c: Ignore -Wpointer-sign diagnostics. (getgrouplist_gids) [HAVE_GETGROUPLIST]: Remove. All uses removed. * m4/mgetgroups.m4 (gl_MGETGROUPS): Revert recent changes. 2015-06-29 Paul Eggert mgetgroups: port to strict OS X * doc/glibc-functions/getgrouplist.texi (getgrouplist): Document the getgrouplist problem. * lib/mgetgroups.c (getgrouplist_gids) [HAVE_GETGROUPLIST]: New macro. (mgetgroups): Use it. * m4/mgetgroups.m4 (gl_MGETGROUPS): Check for OS X signature for getgrouplist. 2015-06-29 Jim Meyering linkat: fix invalid definition of LINKAT_SYMLINK_NOTSUP on OS X It started like this when building coreutils' latest on OS X, invoking ./configure with a nonempty --cache=.cache: lib/linkat.c:46:42: error: operator '||' has no right operand lib/linkat.c: In function 'rpl_linkat': lib/linkat.c:330:27: error: #if with no expression Here's linkat.c's line 46: #if !HAVE_LINKAT || LINKAT_SYMLINK_NOTSUP Here's some context: $ grep linkat_nofoll .cache gl_cv_func_linkat_nofollow=${gl_cv_func_linkat_nofollow=no} $ grep LINKAT_SYM lib/config.h #define LINKAT_SYMLINK_NOTSUP The problem is that m4/linkat.m4's gl_FUNC_LINKAT uses AC_CACHE_CHECK to set LINKAT_SYMLINK_NOTSUP, but that violates a tenet of AC_CACHE_CHECK: it must have no side effect other than setting its cache variable. What happens is that when the cache is set, we'd skip the code in that AC_CACHE_CHECK call, and leave LINKAT_SYMLINK_NOTSUP defined to whatever value it happened to have in configure's environment. In my case, it was not defined, so this later code: AC_DEFINE_UNQUOTED([LINKAT_SYMLINK_NOTSUP], [$LINKAT_SYMLINK_NOTSUP], [Define to 1 if linkat can create hardlinks to symlinks]) would emit code with an empty RHS. * m4/linkat.m4 (gl_FUNC_LINKAT): Move the setting of $LINKAT_SYMLINK_NOTSUP out of the AC_CACHE_CHECK code block. 2015-06-28 Jim Meyering mountlist: avoid an unused-label warning on OS X * lib/mountlist.c (read_file_system_list) [MOUNTED_GETMNTINFO]: Building on OS X, I saw a warning about the "free_then_fail" label being unused. Give it the _GL_UNUSED_LABEL attribute. error.c: correct printf-style format: %d -> %u * lib/error.c (error_at_line): Correct __fxprintf format to use %u, rather than %d, to match the type of "line_number", unsigned int. 2015-06-25 Pádraig Brady fts: avoid reading beyond the heap allocation GCC 5.1.1 with -O2 and -fsanitize=address reports a read of size 4 from a heap object of size 3 is indeed invalid, though this may be due to incorrect padding assumptions by GCC, see: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66661 * lib/fts.c (fts_alloc): Increase allocation to alignof(FTSENT). * modules/fts: Depend on stdalign. 2015-06-24 Pádraig Brady savedir: avoid undefined behavior in qsort call GCC 5.1.1 -fsanitize=undefined with glibc 2.21 is returning: "runtime error: null pointer passed as argument 1, which is declared to never be null" * lib/savedir.c (streamsavedir): Avoid the call with no entries. 2015-06-24 Pádraig Brady userspec: avoid undefined behavior in gettext call GCC 5.1.1 -fsanitize=undefined with glibc 2.21 is returning: "runtime error: null pointer passed as argument 2, which is declared to never be null" * lib/userspec.c (parse_with_separator): Avoid passing NULL to gettext() 2015-06-20 Glenn Morris gitlog-to-changelog: improve gitmerge.el commits Let the Emacs ChangeLog generation process exclude "skipped" messages from merge commits (Bug#20717). * build-aux/gitlog-to-changelog: Handle gitmerge.el skipped commits. 2015-06-20 Paul Eggert wchar: fix MinGW compilation warnings This lets Texinfo compile cleanly. See Eli Zaretskii in: http://lists.gnu.org/r/bug-gnulib/2015-06/msg00050.html * lib/wchar.in.h: Do not use special invocation convention on MinGW. 2015-06-20 Daiki Ueno uniname/uniname-tests: use pristine data files For copyright and maintenance reasons, use the data files from UCD without modification. * tests/uniname/test-uninames.c (FIELDLEN): Remove. (getfield): Remove. (aliases_count): New global variable. (fill_names): Skip comments and empty lines in the input. Don't use getfield. (fill_aliases): Likewise. (main): Change the expected command line arguments to: NAMES... ["--" ALIASES...]. * tests/uniname/test-uninames.sh: Adjust to the change in test-uninames.c. * tests/uniname/UnicodeDataNames.txt: Remove. * tests/uniname/UnicodeData.txt: New file, from Unicode 8.0.0. * tests/uniname/NameAliases.txt: Use the pristine copy of the data file from Unicode 8.0.0. 2015-06-19 Pádraig Brady linked-list, linkedhash-list: avoid compiler warnings * lib/gl_anytree_list2.h: Add _GL_ATTRIBUTE_PURE to avoid -Werror=suggest-attribute=pure (from GCC 5.1.1). 2015-06-19 Daiki Ueno libunistring: bump minimum version to 0.9.6 * all modules depending on updated Unicode data: Regenerate. The modules are listed by a script that does: - for each file listed by: git show --oneline --name-only 705f4efc - deduce the containing modules, based on "Files:" - deduce the modules which depend on the containing modules, based on "Depends-on:" 2015-06-18 Daiki Ueno uniname/uniname: update to Unicode 8.0.0 * lib/uniname/uninames.h: Regenerate. * tests/uniname/NameAliases.txt: Update from Unicode 8.0.0. * tests/uniname/UnicodeDataNames.txt: Update from Unicode 8.0.0. 2015-06-18 Daiki Ueno libunistring: update to Unicode 8.0.0 * lib/gen-uni-tables.c (SIZEOF): New macro. (output_numeric): Increase the maximum number of fractions from 128 to 160. Increase the level3 value width from 7 bits to 8 bits. Use SIZEOF instead of a hard-coded integer. (output_blocks): Decrease the cut-off threshold from 0x30000 to 0x28000. (fill_blocks): Increase the maximum number of blocks from 256 to 384. Use SIZEOF instead of a hard-coded integer. (get_lbp): Adjust to new characters added in Unicode 8.0.0. * lib/unictype/numeric.c (uc_numeric_value): Adjust the level3 value width. * lib/unilbrk/lbrktables.c (unilbrk_table): Implement LBP21b and a new case added to LBP22. * lib/uniwidth/width.c (nonspacing_table_data): Add U+08E3, U+A69E, U+FE2E..U+FE2F, U+111CA..U+111CC, U+11300, U+115DC..U+115DD, U+1171D..U+1171F, U+11722..U+11725, U+11727..U+1172B, U+1DA00..U+1DA36, U+1DA3B..U+1DA6C, U+1DA75, U+1DA84, U+1DA9B..U+1DA9F, and U+1DAA1..U+1DAAF. * tests/uniwidth/test-uc_width2.sh: Same updates as in lib/uniwidth/width.c. * all generated files under lib/uni* and tests/uni*: Regenerate. 2015-06-16 Pádraig Brady gnu-web-doc-update: add --mirror to remove stale files * build-aux/gnu-web-doc-update: Add a --mirror option to remove out of date files from the CVS server. Since this is usually appropriate, a prompt is given when the option is not specified, along with the `cvs remove` command that would be run. 2015-06-06 Paul Eggert acl-permissions: pacify -Wsuggest-attribute=const Problem reported by Masanari Iida in: http://bugs.gnu.org/20753 * lib/acl-internal.h (free_permission_context): Declare with attribute const if ! (defined USE_ACL && (HAVE_ACL_GET_FILE || defined GETACL)). fsync: document AIX misbehavior * doc/posix-functions/fsync.texi (fsync): Document failure on AIX with read-only file descriptor. 2015-06-05 Jonathan Perkin (tiny change) stdio: Don't redefine gets when using C++ * lib/stdio.in.h (gets): Disable warning on C++. 2015-06-05 Paul Eggert acl-permissions: port to AIX, C89 HP-UX Problems reported by Michael Felt. * lib/file-has-acl.c (file_has_acl) [HAVE_STATACL]: * lib/get-permissions.c (get_permissions) [USE_ACL && HAVE_STATACL]: * lib/readutmp.c (read_utmp) [UTMP_NAME_FUNCTION]: * lib/set-permissions.c (set_acls) [HAVE_ACLX_GET && ACL_AIX_WIP]: Add cast for AIX, whose system calls are declared to accept char * even though the arguments are really char const *. * lib/get-permissions.c (get_permissions): If USE_ACL && HAVE_GETACL /* HP-UX */, don't assume C99. If USE_ACL && HAVE_STATACL /* older AIX */, add missing decl that broke a build. * lib/mountlist.c (read_file_system_list) [MOUNTED_VMOUNT]: Rework types to pacify xlc. 2015-06-03 Pádraig Brady vasprintf-posix: avoid compiling vasnprintf where possible * modules/vasprintf-posix: Avoid compiling the large vasnprintf module where not required. For example on a GNU/Linux system when gnulib-tool is run with the --conditional-dependencies option. 2015-06-02 Pádraig Brady file-has-acl: fix build on Mac OS X 10 This reverts commit f1b37e3a which doesn't work on Mac OS X >= 10.4 which has an incompatible 6 parameter getxattr() call. * doc/glibc-functions/getxattr.texi: Mention the divergent getxattr() call on Mac OS X >= 10.4. * doc/glibc-functions/fgetxattr.texi: Likewise. * lib/file-has-acl.c: Revert to more complete combined check. * m4/acl.m4 (gl_FILE_HAS_ACL): Likewise. Reported by Jack Howarth. 2015-06-02 Pádraig Brady prefix-gnulib-mk: remove no longer needed special case * build-aux/prefix-gnulib-mk (prefix): Since commit e3704b9c, continued lib_SOURCES lines are no longer present, so special case handling of such entries is not required. 2015-06-01 Pádraig Brady acl: don't depend on the deprecated qacl module * modules/acl (Depends-on): Use q{copy,set}-acl instead. 2015-06-01 Pádraig Brady gnulib-tool: concatenate lib_SOURCES to a single line * gnulib-tool: Refactor the line merging sed logic, and use that to output a single lib_SOURCES line for each module. gnulib using projects often postprocess this output to prepend subdir paths to each item, and having a single line simplifies this processing allowing better decoupling from the gnulib-tool output. 2015-06-01 Pavel Fedin pthread_sigmask: discount system version if a simple macro (trivial) MinGW64 has: #define pthread_sigmask(H, S1, S2) 0 * m4/pthread_sigmask.m4 (gl_FUNC_PTHREAD_SIGMASK): Call the function to ensure it's available. 2015-05-31 Pádraig Brady readlinkat: avoid OS X 10.10 trailing slash bug * doc/posix-functions/readlink.texi: Mention that OS X 10.10 has this bug. * doc/posix-functions/readlinkat.texi: Likewise. Also mention that OS X 10.10 has this function. * lib/readlinkat.c (rpl_readlinkat): Handle the trailing slash bug, as done for readlink(). * m4/readlinkat.m4 (gl_FUNC_READLINKAT): Check for the readlink() trailing slash bug, and assume readlinkat() has the same issue. Also fix a typo where $gl_cv_decl_readlink_works was tested, rather than the correct $gl_cv_decl_readlinkat_works. 2015-05-29 Andreas Gruenbacher acl-permissions: Fix build on Mac OS X and older AIX (Bug#20681) * lib/set-permissions.c (set_acls): Fix more errors introduced in the acl module rewrite. acl-permissions: Fix build on Solaris and Cygwin Reported by Tom G. Christensen : * lib/set-permissions.c (set_acls): The count, entries, ace_count, and ace_entries variables have moved into struct permission_context but they were still accessed as local variables here. 2015-05-29 Pádraig Brady linkat: avoid OS X 10.10 trailing slash with symlink bug On Darwin 14.3.0 linkat(,"path1",,"dangling_symlink/",) causes the symlink to be dereferenced, and if it points to a non existent file, that file will be created as a hard link to "path1". This fixes a test failure in test-linkat.c. * m4/linkat.m4 (gl_FUNC_LINKAT): Augment the test with this case. The existing workaround in linkat.c for trailing slash issues, suffices for this case. * doc/posix-functions/linkat.texi: Add OS X 10.10 to the list of platforms with trailing slash issues. 2015-05-28 Pádraig Brady unlinkat: handle ignoring of ".." on Darwin 14 * lib/unlinkat.c: unlinkat() has the same bug as unlink() on Mac OS X 10.10, where it ignores paths with a trailing "..", so handle in the same manner. * m4/unlinkat.m4: Comment on this Darwin issue. * doc/posix-functions/unlink.texi: Update the latest version where the issue was seen. * doc/posix-functions/unlinkat.texi: Mention this issue. Fixes a test failure in test-unlinkat.c. 2015-05-27 Paul Eggert qacl: split into qcopy-acl and qset-acl Emacs needs the former, but not the latter. * modules/acl-permissions: New file, containing most of the old qacl. * modules/file-has-acl (Depends-on): Depend on acl-permissions, not qacl. * modules/qacl: Now merely depends on qcopy-acl and qset-acl. * modules/qcopy-acl, modules/qset-acl: New files. * MODULES.html.sh (File system functions): Mention the new modules, and mention qacl while we're at it. 2015-05-27 Glenn Morris gitlog-to-changelog: new option --ignore-line (This patch is imported from the GNU Emacs master.) This option ignores individual commit lines matching a pattern. * build-aux/gitlog-to-changelog: Add --ignore-line option. 2015-05-27 Andreas Gruenbacher qacl: Reimplement qset_acl and qcopy_acl (Bug#20666) Implement get_permissions and set_permissions primitives for getting all the permissions of a file, storing them, and later setting them. (In the minimal case, the permissions consist only of a file mode.) Reimplement qset_acl and qcopy_acl based on these new primitives: this avoids code duplication and makes error handling more consistent. The Solaris and Cygwin code still uses duplicate code paths for setting a file mode while making sure that no acls exist and setting an explicit acl; this is no worse than before, but could be cleaned up. The AIX code still doesn't read ACLs, it only makes sure that acls don't get in the way when setting a file mode. * lib/acl-internal.h (struct permission_context): New data structure. (get_permissions, set_permissions, free_permission_context): Declare. * lib/acl-internal.c (free_permission_context): New helper function. * lib/get-permissions.c (get_permissions): New helper function split off from qcopy_acl. * lib/set-permissions.c: (set_acls_from_mode): On Solaris, Cygwin, and AIX, set a file's permissions based only on a file mode. (acl_from_mode, context_acl_from_mode, context_aclv_from_mode): All other platforms construct a temporary acl from the file mode and set that acl in the same way as setting an acl read from the source file. This should help avoid code duplication and inconsistent / buggy behavior. (set_acls): New helper function Split off from qcopy_acl. (chmod_or_fchmod): Moved here from qset-acl.c. (set_permissions): New helper function. * lib/qcopy-acl.c (qcopy_acl): Rewrite using get_permissions and set_permissions. * lib/qset-acl.c (qset_acl): Rewrite using set_permissions. * modules/qacl: Add get-permissions.c and set-permissions.c. file-has-acl: Split feature tests again (Bug#20667) * lib/file-has-acl.c: Instead of testing for XATTR_NAME_POSIX_ACL_ACCESS and XATTR_NAME_POSIX_ACL_DEFAULT, define them when needed. * m4/acl.m4 (gl_FILE_HAS_ACL): With that, Paul's GETXATTR_WITH_POSIX_ACLS change shouldn't be needed anymore. 2015-05-27 Pádraig Brady string: fix build failure on BSD/OSX with FORTIFY_SOURCE This avoids a conflict with "FORTIFY_SOURCE" variants of the string functions when they're replaced on NetBSD-6.0.1 and Darwin-14.3.0 at least. * lib/string.in.h: Avoid including our "lib/string.h" while including the system . 2015-05-26 Eric Blake stdio: limit __gnu_printf__ witness to gcc 4.4+ * lib/error.h (_GL_ATTRIBUTE_SPEC_PRINTF): Move gcc version probe... * m4/stdio_h.m4 (gl_STDIO_H): ...here. error: use correct printf attributes on mingw * lib/stdio.in.h (_GL_ATTRIBUTE_SPEC_PRINTF): New define. inttypes: force correct mingw PRIdMAX even without * modules/inttypes (Depends-on): Require extensions, so that mingw always uses GNU style inttypes. * lib/inttypes.in.h: On mingw, include . stdio: fix probe on mingw under gcc 5.1 * m4/stdio_h.m4 (gl_STDIO_H): Change to compile test, to work around new gcc preprocessor rules. 2015-05-07 Glenn Morris gitlog-to-changelog: parse "Tiny-change" * build-aux/gitlog-to-changelog: Treat "Tiny-change" like "Copyright-paperwork-exempt". (Bug#20324) 2015-05-06 Pádraig Brady doc: document glibc posix_fallocate() issues * doc/posix-functions/posix_fallocate.texi: Mention the glibc efficiency problems and issues with NFS. 2015-05-05 Karl Berry * build-aux/gendocs.sh (usage): document new css default for HTML (--htmlarg). 2015-04-29 Paul Eggert extern-inline: no need for workaround in GCC 5.1 * doc/extern-inline.texi (extern inline): * m4/extern-inline.m4 (gl_EXTERN_INLINE): GCC bugs 54113 and 63877 are fixed in GCC 5.1, so don't work around these bugs in GCC 5.1 and later. Maybe in a decade or two we can remove these workarounds. 2015-04-28 Pádraig Brady eealloc, pagealign_alloc, xalloc: avoid clang warnings Avoid [-Wunknown-attributes] warnings like: warning: unknown attribute '__alloc_size__' ignored * lib/xalloc.h: Don't use the __alloc_size__ attribute with clang, as support has been fully removed as of clang 3.5: https://github.com/llvm-mirror/clang/commit/c047507a * lib/eealloc.h: Likewise. * lib/pagealign_alloc.h: Likewise. 2015-04-27 Paul Eggert tests: pacify GCC 5.1's stricter printf checking * tests/test-dirname.c (main): * tests/test-getaddrinfo.c (simple): * tests/test-getlogin.c (main): * tests/test-getndelim2.c (main): * tests/test-inttostr.c (CK): * tests/test-md5.c (main): * tests/test-read-file.c (main): * tests/test-sha1.c (main): Fix mismatches between printf format and value signedness. * tests/test-inttostr.c (FMT, CAST_VAL, V_min, V_max): Remove, as CAST_VAL always returned a value of type uintmax_t. fts: port to GCC 5.1 with --enable-gcc-warnings Without this fix, GCC 5.1 (correctly) warns about a subscript error on the fts_name component of FTSENT. It's actually a flexible member, so define it that way on C99 or later hosts. * lib/fts.c (fts_alloc): Use offsetof, not sizeof, for a structure that now has a flexible array member. * lib/fts_.h (__FLEXIBLE_ARRAY_MEMBER): New macro. (FTSENT): fts_name is now flexible on C99-or-later platforms. * modules/fts (Depends-on): Add flexmember. 2015-04-26 Paul Eggert file-has-acl: port to CentOS 6 Problem reported by Tom G. Christensen in: http://lists.gnu.org/r/bug-gnulib/2015-04/msg00074.html * lib/file-has-acl.c: Use GETXATTR_WITH_POSIX_ACLS instead of a combination of HAVE_SYS_XATTR_H, HAVE_LINUX_XATTR_H, and HAVE_GETXATTR. * m4/acl.m4 (gl_FILE_HAS_ACL): Test fot the entire combination of linux/xattr.h, sys/xattr.h, getxattr, XATTR_NAME_POSIX_ACL_ACCESS, and XATTR_NAME_POSIX_ACL_DEFAULT, since that's what file-has-acl.c actually needs. 2015-04-26 Pádraig Brady file-has-acl: always return false when ACLs aren't supported * lib/file-has-acl.c (file_has_acl): Consistent with other paths, change the GNU/Linux getxattr path, to transform "not supported" errors to a false return rather than an error. This is handled within file_has_acl() due to the platform specific tests to determine if ACLs are not supported. 2015-04-25 Paul Eggert gettext: propagate po/Makefile.in.in too * build-aux/po/Makefile.in.in: Copy from latest gettext. * config/srclist.txt: In build-aux/po, copy Makefile.in.in and remove-potcdate.sin from $GETTEXT. This fixes a version mismatch between Makefile.in.in and the gettext-runtime m4 files. 2015-04-24 Paul Eggert file-has-acl: new module, split from acl And add a new module file-has-acl-tests to match. I ran into a problem with the recent changes to the acl module, as they introduced a typo 'test use_xattrs = 0' into 'configure'. When using the fixed version with Emacs, I discovered that file-has-acl wasn't separated out well enough for Emacs (e.g., it had multiple libraries, but needed only one), so I fixed that too. * NEWS: Document this incompatible change. * modules/file-has-acl, modules/file-has-acl-tests: New files. * m4/acl.m4 (gl_FUNC_ACL_ARG): New macro, split from gl_FUNC_ACL. Initialize gl_need_lib_has_acl. (gl_FUNC_ACL): Require it. Simplify use of 'test'. Set LIB_HAS_ACL if gl_need_lib_has_acl. Move the file-has-acl.c-relevant stuff to ... (gl_FILE_HAS_ACL): ... this new macro. Rewrite to fix 'test use_xattrs = 0' typo, and omit some needless work. Set gl_need_lib_has_acl=1 if we'll need LIB_HAS_ACL to be set when gl_FUNC_ACL is called. * modules/acl (Files, lib_SOURCES): Remove lib/file-has-acl.c. (Link): Remove $(LIB_HAS_ACL). * modules/acl-tests (Files, Depends-on, configure.ac, TESTS) (check_PROGRAMS): Move stuff relevant to file-has-acl to modules/file-has-acl-tests. (test_file_has_acl_LDADD): Move to modules/file-has-acl-tests. manywarnings: add GCC 5.1 warnings * build-aux/gcc-warning.spec: Add -Wabi=, -Warray-bounds, -Warray-bounds=, -Wc++14-compat, -Wc90-c99-compat, -Wc99-c11-compat, -Wshadow-ivar, -Wsized-deallocation, -Wsuggest-override, -Wuse-without-only. Change -Wnormalized=... operands to match 5.1. * m4/manywarnings.m4 (gl_MANYWARN_ALL_GCC): Add -Wbool-compare, -Wchkp, -Wdesignated-init, -Wdiscarded-array-qualifiers, -Wdiscarded-qualifiers, -Wformat-signedness, -Wincompatible-pointer-types, -Wint-conversion, -Wlogical-not-parentheses, -Wmemset-transposed-args, -Wodr, -Wshift-count-negative, -Wshift-count-overflow, -Wsizeof-array-argument, -Wsuggest-final-methods, -Wsuggest-final-types, -Wswitch-bool. Remove -Warray-bounds, and add -Warray-bounds=2 as a special case. 2015-04-21 Simon Josefsson doc: update FDL template to match FDL examples. * doc/alloca-opt.texi: * doc/alloca.texi: * doc/c-ctype.texi: * doc/c-strcase.texi: * doc/c-strcaseeq.texi: * doc/c-strcasestr.texi: * doc/c-strstr.texi: * doc/c-strtod.texi: * doc/c-strtold.texi: * doc/ctime.texi: * doc/error.texi: * doc/gcd.texi: * doc/gnulib-tool.texi: * doc/inet_ntoa.texi: * doc/intprops.texi: * doc/lib-symbol-visibility.texi: * doc/maintain.texi: * doc/parse-datetime.texi: * doc/quote.texi: * doc/regexprops-generic.texi: * doc/standards.texi: Remove spurious 'with' in FDL license template. 2015-04-21 Paul Eggert lstat: fix cross-compilation 'ln -s' problem * m4/lstat.m4 (gl_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Have the test program call 'symlink' rather than a separate script run 'ln -s'; this is more likely to work in cross-compilation environments. Reported by Pavel Fedin in: http://lists.gnu.org/r/bug-gnulib/2015-04/msg00060.html 2015-04-16 Ludovic Courtès gendocs.sh: default to a common CSS style sheet for HTML output * build-aux/gendocs.sh (htmlarg): Change default value. 2015-04-15 Mats Erik Andersson gnulib-tool: output bold attribute more portably * gnulib-tool (func_show_module_list): Change hexadecimal numbers to octal in BOLD_ON and BOLD_OFF. The use of hex encoded numbers as arguments to `printf' is not portable, and is not claimed by POSIX. This is the case with FreeBSD. 2015-04-15 Andreas Gruenbacher qacl: Simplify HP-UX acl_nontrivial check * lib/acl-internal.c: Remove struct stat parameter from HP-UX's version of acl_nontrivial. Check if the acl has at most three entries instead (it must have exactly three entries according to the HP-UX documentation). Ignore uids and gids as long as an entry is either for a user (i.e., the owner), a group (i.e., the owning group), or others. * lib/acl-internal.h: Change HP-UX's acl_nontrivial prototype. * lib/qcopy-acl.c (qcopy_acl): With that, we no longer need to stat the file. 2015-04-15 Andreas Gruenbacher acl: On Linux, check for acls without libacl On Linux, use the getxattr syscall instead of the acl_extended_file libacl library function to check for the presence of acls, avoiding a library. * lib/file-has-acl.c: Include xattr headers if we have them. (file_has_acl): On Linux, use getxattr(). * m4/acl.m4 (gl_FUNC_ACL): Define LIB_HAS_ACL as the libraries to link with for file_has_acl(). Check for xattr headers and getxattr(). 2015-04-14 Ángel González tempname: avoid unused parameter warnings (trivial) * lib/tempname.c (try_dir): Tag with __GL_UNUSED. (try_nocreate): Likewise. 2015-04-14 HIRAMATSU Yoshifumi fseeko: fix build failure on NetBSD >= 6 (trivial) * lib/fseeko.c (feeko): NetBSD 6 changed the definition of _offset from 'fpos_t struct' to __off_t, which is a typedef of __int64_t. 2015-04-09 Paul Eggert gitlog-to-changelog: port to MS-Windows * build-aux/gitlog-to-changelog (git_dir_option): Use strftime with "%Y-%m-%d", not "%F", to avoid a bug in MS-Windows Perl. Reported by Eli Zaretskii in: http://lists.gnu.org/r/emacs-devel/2015-04/msg00504.html 2015-04-07 Karl Berry gendocs: new option --tex for passing args to texi2dvi. * build-aux/gendocs.sh: new option --tex, default -t @finalout. (TEXI2DVI): cut to just command name. (usage): mention new option, and update copyright. : use it. 2015-04-07 Karl Berry * config/srclistvars.sh (GETTEXT): new definition. * config/srclist.txt: use it for gettext .m4 files. Thread starting at http://lists.gnu.org/r/bug-gnulib/201 and confirmed at http://lists.gnu.org/r/bug-gnulib/2015-02/msg00146.html and continuing into April. 2015-04-07 Daiki Ueno uniname/uniname-tests: fix failure due to alias Reported by Jack Howarth in: . * tests/uniname/test-uninames.c (name_has_alias): New function. (test_inverse_lookup): Exclude character name with valid alias, from randomly generated character names. (main): Fill unicode_aliases before calling test functions. 2015-04-03 Giuseppe Scrivano hash: remove deprecated hash_insert0 function * lib/hash.h (hash_insert0): Remove deprecated function. * lib/hash.c (hash_insert0): Likewise. 2015-04-02 Pádraig Brady mountlist: remove dependency on libmount * lib/mountlist.c (read_file_system_list): Parse /proc/self/mountinfo directly, rather than depending on libmount, which has many dependencies due to its dependence on libselinux, as detailed at: http://lists.gnu.org/r/bug-gnulib/2015-01/msg00063.html Note we restrict this to __linux__ as that's probably where this interface will remain. If ever porting, it would be best to first pull the makedev() wrapper from coreutils to a gnulib module. Note also we don't add a getline dependency to the mountlist module, as all Linux versions are sufficient. 2015-04-02 Paul Eggert stddef: port to pre-C11 GCC on x86 On this platform, max_align_t should have an alignment of 8 even though the storage alignments of double, long, etc. max out at 4. Inspired by a comment of Andreas Schwab's here: https://sourceware.org/ml/libc-alpha/2015-04/msg00017.html * lib/stddef.in.h (_GL_STDDEF_ALIGNAS) [!HAVE_MAX_ALIGN_T]: New macro. (max_align_t) [!HAVE_MAX_ALIGN_T]: Use it. * tests/test-stddef.c: Test __alignof__ too, if available. 2015-03-24 Pádraig Brady quotearg-simple-tests: add missing gl_FUNC_MMAP_ANON dependency * modules/quotearg-simple-tests: Reference m4/mmap-anon.m4 2015-03-24 Tobias Stoeckmann yesno: make EOL optional in ENABLE_NLS case also (trival) * lib/yesno.c (yesno): Check for EOL before replacing. * tests/test-yesno.sh: Add a test case (test along with gettext). 2015-03-22 Paul Eggert fdopendir-tests: test it does not close its arg * tests/test-fdopendir.c (main): Test that fdopendir does not close its argument. From a suggestion by David Grayson in: http://lists.gnu.org/r/bug-gnulib/2015-03/msg00039.html 2015-03-20 Paul Eggert gitlog-to-changelog: trim trailing white space * build-aux/gitlog-to-changelog (main): Trim trailing white space from commit message lines. This is helpful for processing the GNU Emacs repository, which dates back to 1985 and contains a lot of such lines. gitlog-to-changelog: new option --ignore-matching * build-aux/gitlog-to-changelog (usage, git_dir_option, main): Support new option --ignore-matching=PAT, which ignores all commit messages whose first line matches PAT. 2015-03-19 Paul Eggert fdopendir: port better to MinGW * lib/fdopendir.c (fd_clone_opendir) [REPLACE_FCHDIR]: Use 'dup' if dirfd fails. Suggested by Eli Zaretskii in: http://lists.gnu.org/r/bug-gnulib/2015-03/msg00033.html * modules/fdopendir (Depends-on): Add dirfd. 2015-03-18 Paul Eggert fdopendir: fix typo in comment * lib/fdopendir.c (fdopendir_with_dup): REPLACE_FCHDIR was misspelled. 2015-03-09 Eric Blake error: document all entry points provided * doc/glibc-functions/error_print_progname.texi (error_print_progname): Mention the error module. * doc/glibc-functions/error_at_line.texi (error_at_line): Likewise. * doc/glibc-functions/error_message_count.texi (error_message_count): Likewise. * doc/glibc-functions/error_one_per_line.texi (error_one_per_line): Likewise. 2015-03-03 Paul Eggert vasnprintf: pacify clang 3.5.0 Problem reported by Werner Lemberg in: http://lists.gnu.org/r/bug-gnulib/2015-03/msg00000.html * lib/vasnprintf.c (VASNPRINTF): Omit casts that clang objects to. The casts aren't needed, since the characters in question are ASCII. 2015-02-24 Paul Eggert glob, etc.: port to MSVC v18 on MS-Windows 8.1 * lib/dirent--.h (GNULIB_defined_opendir): * lib/dirent.in.h (GNULIB_defined_opendir) (GNULIB_defined_closedir): * lib/getcwd.c, lib/glob.c, lib/mountlist.c (opendir, closedir): #undef only if Gnulib defined it. poll: port to MSVC v18 on MS-Windows 8.1 Problem reported by Gisle Vanem in: http://lists.gnu.org/r/bug-gnulib/2015-02/msg00139.html * lib/poll.c: Always include and . * modules/poll (Depends-on) [!HAVE_POLL || REPLACE_POLL]: Add sys_socket. 2015-02-24 Pádraig Brady tests: support stderr verification with returns_() * tests/init.sh (returns_): Disable tracing for this wrapper function, so that stderr of the wrapped command is unchanged, allowing for verification of the contents. 2015-02-24 Pavel Hrdina passfd: avoid valgrind uninitalised data warning * lib/passfd.c (sendfd): Reset the msg_controllen of msghdr, to include just the fd we've initialized, rather than including the extra space used for alignment. 2015-02-23 Paul Eggert uniwbrk/u32-wordbreaks-tests: fix copyright * tests/uniwbrk/test-uc-wordbreaks.c: Fix copyright date. dup2: doc and test for Android bug Reported by Kevin Cernekee in: http://lists.gnu.org/r/bug-gnulib/2015-02/msg00125.html * doc/posix-functions/dup2.texi (dup2): Document the bug. * m4/dup2.m4 (gl_FUNC_DUP2): Test for the bug. 2015-02-23 Kevin Cernekee Replace dup2() on Android * m4/dup2.m4 (gl_FUNC_DUP2): Android implements dup2() using dup3(). Since dup3(fd, fd) fails but dup2(fd, fd) should pass, test-dup2 fails. Using rpl_dup2() fixes this because it has an explicit test for this condition. 2015-02-22 Paul Eggert Android doesn't define RLIM_SAVED_* Portability problem reported by Kevin Cernekee in: http://lists.gnu.org/r/bug-gnulib/2015-02/msg00122.html * doc/posix-headers/sys_resource.texi (sys/resource.h): Mention the portability problem. * lib/getdtablesize.c (RLIM_SAVED_CUR, RLIM_SAVED_MAX): Define if not defined. * m4/dup2.m4 (gl_FUNC_DUP2): * m4/fcntl.m4 (gl_FUNC_FCNTL): Likewise. 2015-02-21 Paul Eggert vasnprintf-posix-tests: use consistent test * tests/test-vasnprintf-posix.c (test_function): Use "<" in assert instead of "<=", for consistency with other tests. 2015-02-20 Paul Eggert printf, isinf, etc.: noncanonical != NaN Do not require that isinf, printf, etc. treat noncanonical values as NaNs. Instead, require only that they do not crash. Problem reported by Joseph Myers in: https://sourceware.org/ml/libc-alpha/2015-02/msg00244.html * doc/posix-functions/dprintf.texi (dprintf): * doc/posix-functions/fprintf.texi (fprintf): * doc/posix-functions/isfinite.texi (isfinite): * doc/posix-functions/isinf.texi (isinf): * doc/posix-functions/isnan.texi (isnan): * doc/posix-functions/printf.texi (printf): * doc/posix-functions/snprintf.texi (snprintf): * doc/posix-functions/sprintf.texi (sprintf): * doc/posix-functions/vdprintf.texi (vdprintf): * doc/posix-functions/vfprintf.texi (vfprintf): * doc/posix-functions/vprintf.texi (vprintf): * doc/posix-functions/vsnprintf.texi (vsnprintf): * doc/posix-functions/vsprintf.texi (vsprintf): Document this. * m4/isfinite.m4 (gl_ISFINITEL_WORKS): * m4/isinf.m4 (gl_ISINFL_WORKS): * m4/isnanl.m4 (gl_FUNC_ISNANL_WORKS): * m4/printf.m4 (gl_PRINTF_INFINITE_LONG_DOUBLE): * tests/test-isfinite.c (test_isfinitel): * tests/test-isinf.c (test_isinfl): * tests/test-isnan.c (test_long_double): * tests/test-isnanl.h (main): * tests/test-snprintf-posix.h (test_function): * tests/test-sprintf-posix.h (test_function): * tests/test-vasnprintf-posix.c (test_function): * tests/test-vasprintf-posix.c (test_function): Test only that noncanonical values do not cause crashes, not that they are treated as NaNs. In some cases this means a larger output buffer is needed. 2015-02-20 Jaroslav Skarvada fts: remove redundant close() (trivial) * lib/fts.c (fts_read): Remove redundant call to close(). Spotted by coverity. 2015-02-20 Paul Eggert getdtablesize: port better for Android Problem reported by Kevin Cernekee in: http://lists.gnu.org/r/bug-gnulib/2015-02/msg00112.html * doc/glibc-functions/getdtablesize.texi (getdtablesize): Mention bug. * lib/getdtablesize.c (getdtablesize): Don't fall back on _SC_OPEN_MAX. Instead, just use getrlimit, taking care to avoid Cygwin bug. poll: fixes for large fds * lib/poll.c (poll): Don't check directly for NFD too large. Don't rely on undefined behavior in FD_SET when an arg exceeds FD_SETSIZE. Always set revents afterwards, even if to zero. * tests/test-poll.c (poll1): Set revents to -1 instead of 0, as that makes the test a bit stricter. 2015-02-19 Kevin Cernekee fcntl: Fix cross compiling * m4/fcntl.m4 (gl_FUNC_FCNTL): Assign the guessed result to the correct variable name (gl_cv_func_fcntl_f_dupfd_works). 2015-02-18 Paul Eggert dup2, fcntl: cross-compile better for Android Problem reported by Kevin Cernekee in: http://lists.gnu.org/r/bug-gnulib/2015-02/msg00109.html * m4/dup2.m4 (gl_FUNC_DUP2): Don't guess no when cross-compiling for a Linux kernel. That kernel bug was fixed on 2009-05-11, and there's little need to cross-compile for older kernels nowadays. * m4/fcntl.m4 (gl_FUNC_FCNTL): When cross-compiling, guess no only for systems where the bug is known to occur (AIX, Cygwin, Haiku). 2015-02-18 Pádraig Brady getopt: don't crash on memory exhaustion * lib/getopt.c (_getopt_internal_r): Use degraded diagnostics on memory exhaustion. In the _LIBC case we use alloca() as is already done in glibc, so we don't need to consider the separate error path in that awkward case. Also fix a memory leak when ambiguous options are present. Reported by Tobias Stoeckmann 2015-02-17 Mike Miller tempname: allow compilation with C++ (trivial) * lib/tempname.h [C++]: Specify extern "C" linkage. * lib/tempname.h (try_tempname): * lib/tempname.c (__try_tempname, __gen_tempname): Rename 'try' to 'tryfunc'. 2015-02-17 Paul Eggert dup2, fcntl: port to AIX * m4/dup2.m4 (gl_FUNC_DUP2): * m4/fcntl.m4 (gl_FUNC_FCNTL): Prefer getrusage (RLIM_NOFILE ...)/rlim_cur to sysconf (_SC_OPEN_MAX). The former works on AIX 7.1 but the latter does not. Also, this may work better with Android; see: http://lists.gnu.org/r/bug-gnulib/2015-02/msg00100.html 2015-02-16 Paul Eggert getdtablesize, dup2, fcntl: port to Android Problem reported by Kevin Cernekee in: http://lists.gnu.org/r/bug-gnulib/2015-02/msg00092.html * doc/glibc-functions/getdtablesize.texi (getdtablesize): Mention that getdtablesize doesn't work on Android. * lib/getdtablesize.c: Use getrlimit substitute only if getdtablesize is declared. This should suffice for Cygwin while not breaking Android. * m4/dup2.m4 (gl_FUNC_DUP2): * m4/fcntl.m4 (gl_FUNC_FCNTL): Prefer sysconf (_SC_OPEN_MAX) to getdtablesize, as the former is standardized but the latter is not, and sysconf works on Android. * m4/getdtablesize.m4 (gl_FUNC_GETDTABLESIZE): Also check that getdtablesize is declared. This removes the need for a special case for Android. 2015-02-16 Kevin Cernekee localename: Implement gl_locale_name_thread_unsafe for Android * lib/localename.c: Android API level >= 21 supports two hardcoded locales: C (POSIX) and C.UTF-8. Distinguish them by checking the internal __locale_t struct. 2015-02-16 Kamil Dudka fts: avoid crash when a cycle is added while traversing This could be triggered by auto-mounting a recursive bind mount. Reported by Michael Chapman in: https://bugzilla.redhat.com/1188498 * lib/fts.c (fts_read): Avoid removing the original hash table item when leaving a directory that caused a cycle, and preserve the FTS_DC flag. 2015-02-16 Daiki Ueno uniname/uniname: support character alias * lib/uniname/gen-uninames.lisp (main): New argument ALIASFILE. Generate one-way mapping from aliases to codepoints in the generated tables. Special case variation selectors to reduce table size. * lib/uniname/uniname.c (unicode_character_name): Special case variation selectors. (unicode_name_character): Special case variation selectors and their aliases. * lib/uniname/uninames.h: Regenerate. * tests/uniname/NameAliases.txt: New file, taken from UCD 7.0.0. * modules/uniname/uniname-tests (Files): Add tests/uniname/NameAliases.txt. * tests/uniname/test-uninames.c: Mark as static. (ALIASLEN): Define. (struct unicode_alias): New struct. (unicode_aliases): New variable. (fill_aliases): New function. (test_alias_lookup): New test function. (main): Run the 'test_alias_lookup' test if the second argument is given. * tests/uniname/test-uninames.sh: Supply NameAliases.txt as the second argument. 2015-02-11 Kevin Cernekee Fix FILE struct compatibility with Android API level >= 21 * lib/stdio-impl.h: Test explicitly for __ANDROID__ instead of __sferror. Recent versions of Bionic's stdio.h no longer define __sferror. * lib/fbufmode.c: Likewise. * lib/fflush.c: Likewise. * lib/fpurge.c: Likewise. * lib/freadable.c: Likewise. * lib/freadahead.c: Likewise. * lib/freading.c: Likewise. * lib/freadptr.c: Likewise. * lib/freadseek.c: Likewise. * lib/fseeko.c: Likewise. * lib/fseterr.c: Likewise. * lib/fwritable.c: Likewise. Assume unbroken ungetc() on Android * m4/ungetc.m4: Add Android case to host OS check. The ungetc() test case passed when running on an Android host, and the code hasn't really changed since 2009. getdtablesize: Fix Android build * m4/getdtablesize.m4: Add Android case to host OS check. Recent NDK versions have this symbol in the .so library (at least 32-bit platforms) but are missing the declaration in the header file, causing the m4 logic to guess incorrectly. localename: Fix Android build * modules/localename (Depends-on): Add langinfo. getugroups: Fix Android build * lib/getugroups.c: Don't reference unsupported {get,set,end}grent functions. euidaccess: Fix Android build * modules/euidaccess (Depends-on): Add fcntl-h to ensure that AT_EACCESS gets declared. linkat_nofollow: Add fallback case for cross compiling * m4/linkat.m4: Guess no for Darwin, yes otherwise. net_if: Handle content-free system headers * m4/net_if_h.m4: Check to make sure actually defines struct if_nameindex. If not, enable the replacement header. signal_h: Fix Android build * lib/signal.in.h: Add Android to the list of platforms that declare pthread_sigmask() in instead of . duplocale: Fix Android build of duplocale-tests * modules/duplocale-tests (Depends-on): Add langinfo, as the header is included by test-duplocale.c (but not by duplocale.c). * modules/duplocale-tests (configure.ac): Check for monetary.h. * tests/test-duplocale.c: Skip test if monetary.h is absent. * doc/posix-headers/monetary.texi: Add Android to the list of platforms missing monetary.h. 2015-02-11 Pádraig Brady tests: avoid recent -Werror=unused-variable regression in test-locale * tests/test-locale.c (main): Reference the variable to avoid the "unused variable" warning. 2015-02-11 Pádraig Brady maint: various whitespace cleanups in tempname * lib/tempname.c: Normalize spacing and line length. * lib/tempname.h: Likewise. * modules/tempname: Likewise. 2015-02-11 Pádraig Brady tests: provide returns_() to simplify exit status checking * tests/init.sh (returns_): A new function for use in tests, to allow for easier checking of return values, where you expect a command to exit with failure status. By checking for a particular exit code, you don't hide any crashes for example. 2015-02-11 Pádraig Brady mountlist: only use libmount when specified There are currently many shared libs dependencies introduced by libmount with associated runtime and virt mem overhead. Therefore don't enable by default. * m4/ls-mntd-fs.m4: Use --with-libmount to enable at build time. 2015-02-08 Daiki Ueno uniname/unimame-tests: don't link with -lunistring * modules/uniname/uniname-tests (Makefile.am): Don't link against $(LIBUNISTRING). Document the rationale why we need to conditionalize the test. 2015-02-07 Paul Eggert fstrcmp: don't assume strlen < INT_MAX * lib/fstrcmp.c: Include stddef.h and stdint.h. (uintptr_t): Remove, as we're now assuming stdint. (OFFSET, EXTRA_CONTEXT_FIELDS, fstrcmp_bounded): Prefer ptrdiff_t to int when the value could exceed INT_MAX if the input string is long. (fstrcmp_bounded): Check for size-calculation overflow. Prefer uintptr_t to size_t when the underlying value is a pointer casted to an unsigned integer. Avoid unnecessary 'buffer != NULL' test. * modules/fstrcmp (Depends-on): Add stdint. diffseq: prefer ptrdiff_t to ssize_t * lib/diffseq.h: In commentary, prefer ptrdiff_t to ssize_t. ptrdiff_t is the natural type for signed indexes. On a few older platforms, ssize_t is narrower than size_t. xalloc: fix typo that suppressed warnings * lib/xalloc.h: Add missing _GL_INLINE_HEADER_END.

Need described by Eli Zaretskii in: http://bugs.gnu.org/19113 2014-11-14 Paul Eggert extern-inline: update commentary about GCC bugs * m4/extern-inline.m4: Add another GCC bug number to comments. 2014-11-13 Daiki Ueno gen-uni-tables: untabify * lib/gen-uni-tables.c: Untabify. 2014-11-13 Daiki Ueno gen-uni-tables: check out-of-range values added to 3-level tables * lib/gen-uni-tables.c (output_category, output_bidi_category) (output_joining_type, output_ident_category): Check out-of-range values added to 3-level tables. 2014-11-13 Daiki Ueno gen-uni-tables: utilize 'assert' * lib/gen-uni-tables.c: Include . (output_category, output_combclass, output_decimal_digit_test) (output_decimal_digit, output_digit_test, output_digit) (output_numeric, get_mirror_value, fill_properties) (fill_property30, is_property_alphabetic) (is_property_default_ignorable_code_point) (is_property_uppercase, is_property_lowercase) (is_property_cased, is_property_case_ignorable) (is_property_changes_when_lowercased, is_property_iso_control) (is_property_math, fill_arabicshaping, output_joining_group) (fill_scripts, fill_blocks, output_lbp, fill_org_wbp) (output_wbp, fill_org_gbp, get_decomposition) (output_decomposition, fill_composition_exclusions) (debug_output_composition_tables, output_composition_tables) (redistribute_casefolding_rules, output_casing_rules): Use 'assert (EXPR);' instead of 'if (!EXPR) abort ();' for better error reporting. 2014-11-13 Daiki Ueno gen-uni-tables: cosmetic improvements * lib/gen-uni-tables.c: Escape newlines in the Emacs file local variables specification. (is_outdigit): Remove unused function. 2014-11-12 Jeroen Roovers (tiny change) fcntl-h-tests: port to PA-RISC GNU/Linux * tests/test-fcntl-h.c (main): Check O_SYNC is different from O_DSYNC. 2014-11-10 Paul Eggert fts: port to C89 Problem reported for MSVC 16 by Gisle Vanem in: http://lists.gnu.org/r/bug-gnulib/2014-11/msg00027.html * lib/fts.c (fts_build): Avoid declaration before statement. 2014-11-06 Paul Eggert unistd: port to iOS Problem reported by André Klitzing in: http://lists.gnu.org/r/bug-gnulib/2014-11/msg00013.html * lib/unistd.in.h (environ): Do not include crt_externs.h on iOS. 2014-11-05 Paul Eggert obstack: do not reject malloc-style obstack_chunkfun, obstack_freefun Problem reported by Alan Modra in: http://lists.gnu.org/r/bug-gnulib/2014-11/msg00007.html * lib/obstack.h (obstack_chunkfun, obstack_freefun): Always cast the function arg, reverting this part of the previous change. 2014-11-04 Paul Eggert obstack: avoid potentially-nonportable function casts * lib/obstack.c (CALL_CHUNKFUN, CALL_FREEFUN): Remove, replacing with ... (call_chunkfun, call_freefun): New static functions. All uses changed. Avoid potentially-nonportable casts. (chunkfun_type, freefun_type): Remove typedefs; no longer used. (_obstack_begin_worker): Omit last two args, since they rely on potentially-nonportable casts. All callers changed. * lib/obstack.h (_OBSTACK_CAST): New macro. Use it everywhere the old API used a potentially-nonportable cast. The new API doesn't cast. (struct obstack): Use unions rather than requiring potentially-nonportable casts. (obstack_chunkfun, obstack_freefun): Return void. 2014-11-03 Alan Modra obstack: fix macro return values * lib/obstack.h (obstack_next_free): Return void *. (obstack_1grow_fast, obstack_blank_fast): Return void. For __GNUC__ macros: (obstack_1grow, obstack_blank): Remove now unnecessary (void) 0. For !__GNUC__ macros: (obstack_make_room, obstack_grow, obstack_grow0) (obstack_ptr_grow_fast, obstack_int_grow_fast): Return void. 2014-11-03 Paul Eggert obstack: do not assume system-supplied obstack is size_t safe * m4/obstack.m4: New file. * modules/obstack (Files): Add it. obstack: port to platforms that #define __alignof__ * lib/obstack.c: Include if !defined __alignof__, not if !_LIBC. We don't know of any platforms that #define __alignof__, but it might be useful in tests. Conversely, glibc assumes GCC. 2014-11-03 Pádraig Brady linkat: don't unconditionally replace on GNU/Linux * m4/linkat.m4 (gl_FUNC_LINKAT): The compile check for AT_SYMLINK_FOLLOW was redundant for a few reasons. It was present to support compiling on new systems but running on the old narrow window of Linux 2.6.1[67]. It setup and cleaned up test files which weren't actually used. On non __linux__ it compile tested AT_SYMLINK_FOLLOW, but that is implicit in the following check. 2014-11-03 Pádraig Brady linkat: wrap to handle symlinks on OS X 10.10 * m4/linkat.m4 (gl_FUNC_LINKAT): linkat() is available on Yosemite but not usable because it doesn't support creating hardlinks to symlinks. Therefore add a generic test for this capability and fallback to our emulation if linkat() fails with ENOTSUP. 2014-11-02 Paul Eggert open, openat: document nonstandard FreeBSD, NetBSD O_NOFOLLOW errno * doc/posix-functions/open.texi (open): * doc/posix-functions/openat.texi (openat): Document that these functions do not set errno to ELOOP when a symlink is opened with O_NOFOLLOW. 2014-10-31 Paul Eggert obstack: add NEWS entry for recent incompatible changes * NEWS: Describe recent changes. 2014-10-30 Pádraig Brady mountlist: don't use libmount to decide on dummy/remote * lib/mountlist.c (read_file_system_list): Don't use the libmount routines to determine whether a file system is dummy or remote, as they're not currently compatible. For example the remoteness is determined on file system type (for which the list seems incomplete), rather than simply checking for a ':' in the device name. Also libmount currently determines that 'tmpfs' is a dummy file system even though it has associated storage. 2014-10-29 Paul Eggert obstack: prefer __alignof__ to alignof This is for portability to pre-4.7 GCC when compiling glibc. See Joseph S. Myers in: http://sourceware.org/ml/libc-alpha/2014-10/msg00703.html * lib/obstack.c (__alignof__) [!_LIBC && !__GNUC__]: New macro, defined by including and using . (MAX): New macro. (DEFAULT_ALIGNMENT, DEFAULT_ROUNDING): Redefine in terms of these. Do not use enums as they are not portable to some broken compilers. * modules/obstack (Depends-on): Depend on alignof, not stdalign. obstack: prefer alignof to calculating alignments by hand * lib/obstack.c: Include . (struct fooalign): Remove. (DEFAULT_ALIGNMENT): Use alignof rather than the old offsetof hack. * modules/obstack (Depends-on): Add stdalign. 2014-10-28 Paul Eggert obstack: use size_t alignments and check for overflow * lib/obstack.c, lib/obstack.h (_obstack_begin, _obstack_begin_1): * lib/obstack.c (_obstack_begin_worker, _obstack_newchunk): * lib/obstack.h (struct obstack.alignment_mask): Use _OBSTACK_SIZE_T, not int, for alignments. * lib/obstack.c (_obstack_newchunk): Fail if the size calculation overflows, e.g., when adding the alignment. 2014-10-29 Alan Modra obstack: 64-bit obstack support, part 3 This finally enables full 64-bit obstack support. The glibc shared library specific code is removed from obstack.c too, and the error handling code conditionally compiled under control of another macro, _OBSTACK_NO_ERROR_HANDLER. * lib/obstack.h: Include string.h earlier. (_OBSTACK_INTERFACE_VERSION): Define. (_OBSTACK_SIZE_T, _CHUNK_SIZE_T): Define as size_t for version 2. * lib/obstack.c: Don't include shlib-compat.h. (OBSTACK_INTERFACE_VERSION): Delete. (_OBSTACK_ELIDE_CODE): Rename from ELIDE_CODE. Define when version 1 glibc code is compatible with version 2. Don't include stdio.h for __GNU_LIBRARY. (obstack_exit_failure, print_and_abort, obstack_alloc_failed_handler): Omit when _OBSTACK_NO_ERROR_HANDLER defined. Include stdio.h here. (_obstack_compat, _obstack, _obstack_newchunk, obstack_free): Delete glibc shared library specific source. obstack: 64-bit obstack support, part 2 This gets us 4G obstack support, without changing ABI compatibility, apart from possibly introducing some signed/unsigned comparison warnings in code that uses obstack.h. a) Replace "int" size parameters, return values, and macro local vars with _OBSTACK_SIZE_T, an "unsigned int" for now. b) Make obstack.chunk_size a _CHUNK_SIZE_T, an "unsigned long" for now. c) Make all obstack macros checking available room use obstack_room. "next_free + desired > chunk_limit" may wrap the lhs for chunks allocated near the top of memory. d) Use unsigned comparisons, and macro locals to support >2G on 32-bit. * lib/obstack.h (_OBSTACK_SIZE_T): Define. Use throughout in place of "int" size parameters, return values and local vars. (_CHUNK_SIZE_T): Define. (struct obstack): Make chunk_size a _CHUNK_SIZE_T. Make temp union use an _OBSTACK_SIZE_T integer type. For __GNUC__ versions of the following macros... (obstack_room): Rename local var. (obstack_make_room): Use obstack_room. (obstack_grow, obstack_grow0, obstack_1grow, obstack_ptr_grow, obstack_int_grow, obstack_blank): Likewise. (obstack_finish): Use unsigned comparison when comparing aligned next_free against chunk_limit. (obstack_free): Cast OBJ to remove possible const qualifier. For !__GNUC__ versions of the following macros... (obstack_make_room): Use obstack_room. (obstack_grow, obstack_grow0, obstack_1grow, obstack_ptr_grow, obstack_int_grow, obstack_blank): Likewise. (obstack_finish): Use unsigned comparision when comparing aligned next_free against chunk_limit. (obstack_free): Use temp.p and same comparisons as __GNUC__ version. * lib/obstack.c (_obstack_begin_worker): Make "size" parameter _OBSTACK_SIZE_T. (_obstack_begin, _obstack_begin_1): Likewise. (_obstack_newchunk): Likewise for length parameter. Use size_t locals. (_obstack_memory_used): Return and use _OBSTACK_SIZE_T local. obstack: 64-bit obstack support, part 1 a) Correct calls to alloc function, to use a size_t arg. "long" is just wrong on targets like x86_64-mingw64 where "long" is 32 bits and "size_t" 64 bits. b) Consolidate _obstack_begin and _obstack_begin1 code. * lib/obstack.h (struct obstack ): Correct prototype to use "size_t" rather than "long". (_obstack_begin, _obstack_begin1): Likewise. (obstack_init, obstack_begin, obstack_specify_allocation_with_arg, obstack_chunkfun): Update alloc function casts. * lib/obstack.c (CALL_CHUNKFUN): Update chunkfun cast. (chunkfun_type, freefun_type): New typdefs. (_obstack_begin_worker): Split out from .. (_obstack_begin, _obstack_begin_1): ..here. obstack: tidy part 2 a) Don't be concerned about "not polluting the namespace with stddef.h symbols" in obstack.h, since gnulib string.h includes stddef.h anyway, and it seems unlikely that anyone would care. b) Don't roll our own slow memcpy in _obstack_newchunk. c) Rename obstack_free to _obstack_free. This makes the naming consistent with other obstack functions and obviates the need for __obstack_free. Ancient obstack.c defined both obstack_free and _obstack_free. We continue to do that for _LIBC via an alias. d) Miscellaneous macro fixes. The expression used to test for gcc-2.8 is clever, but nowadays gcc warns on undefined macros. You'll get an undefined macro warning if simulating an old gcc with -U__GNUC__ -U__GNUC_MINOR__ -D__GNUC__=1. * lib/obstack.h: Include stddef.h unconditionally. Formatting fixes. (PTR_INT_TYPE): Delete, replace with ptrdiff_t. (__obstack_free): Delete, update refs. (_obstack_free): Rename from obstack_free. (__extension__): Avoid undefined macro warning for __GNUC_MINOR__. (obstack_object_size, obstack_room): Parenthesise !__GNUC__ versions. * lib/obstack.c: Don't include stddef.h. (COPYING_UNIT): Delete. (_obstack_begin): Formatting fix. (_obstack_newchunk): Use memcpy to move existing object to new chunk. (_obstack_free): Rename from __obstack_free, update alias. Move undef of obstack_free to where it is needed. obstack: tidy part 1 a) Rename temp fields. temp.tempint and temp.tempptr just looks ugly to me, and result in overlong lines after later patches. b) Move error handling code, to avoid a forward declaration and to simplify later patches in this series. * lib/obstack.h (struct obstack ): Rename fields of union and update all uses. * lib/obstack.c: Include stdlib.h earlier. (obstack_exit_failure, obstack_alloc_failed_handler): Move later in file. (print_and_abort): Remove now redundant forward declaration. 2014-10-24 Paul Eggert socketlib, sockets, sys_socket: Use AC_REQUIRE to pacify autoconf. Without this change, in bleeding-edge fileutils Autoconf complains that gl_SOCKETLIB etc. are AC_REQUIREd after being invoked. * modules/socketlib (configure.ac): AC_REQUIRE gl_SOCKETLIB. * modules/sockets (configure.ac): AC_REQUIRE gl_SOCKETS. * modules/sys_socket (configure.ac): AC_REQUIRE gl_HEADER_SYS_SOCKET. 2014-10-24 Daiki Ueno iconv: avoid false detection of non-working iconv The INBUF arguments of iconv can be either 'const char **' or 'char **'. If CC is g++, the difference causes a compile error and thus leads to a false detection of non-working iconv. Reported by Eli Zaretskii and Werner LEMBERG in: . * m4/iconv.m4 (AM_ICONV_LINK): Try all possible argument types of iconv. Bump serial number. 2014-10-23 Pádraig Brady bootstrap: print more diagnostics for missing programs * build-aux/bootstrap: only suppress stderr when checking for alternative program names. This supports programs issuing non standard error messages. 2014-10-23 Pádraig Brady bootstrap: only update the gnulib submodule * build-aux/bootstrap: Restrict the "submodule update" command to the gnulib path. 2014-10-18 Paul Eggert symlinkat: port to AIX 7.1 * doc/posix-functions/symlinkat.texi (symlinkat): Mention AIX porting problem. * lib/symlinkat.c: Always include errno.h. (rpl_symlinkat) [HAVE_SYMLINKAT]: New function. * lib/unistd.in.h (symlinkat): Add replacement machinery. * m4/symlinkat.m4 (gl_FUNC_SYMLINKAT): Check symlinkat behavior. * m4/unistd_h.m4 (gl_UNISTD_H_DEFAULTS): Add REPLACE_SYMLINKAT. * modules/symlinkat (Depends-on): Add fstatat if REPLACE_SYMLINKAT. (configure.ac): Also compile replacement if REPLACE_SYMLINKAT. * modules/unistd (unistd.h): Substitute REPLACE_SYMLINKAT. readlinkat: port to AIX 7.1 * doc/posix-functions/readlink.texi (readlink): * doc/posix-functions/readlinkat.texi (readlinkat): Mention AIX porting problem. * lib/readlinkat.c (rpl_readlinkat) [HAVE_READLINKAT]: New function. * lib/unistd.in.h (readlinkat): Add replacement machinery. * m4/readlinkat.m4 (gl_FUNC_READLINKAT): Check readlinkat signature. * m4/unistd_h.m4 (gl_UNISTD_H_DEFAULTS): Add REPLACE_READLINKAT. * modules/readlinkat (configure.ac): Also compile replacement if REPLACE_READLINKAT. * modules/unistd (unistd.h): Substitute REPLACE_READLINKAT. 2014-10-12 Karl Berry * doc/posix-functions/dirname.texi: remove spurious {. 2014-09-28 Ben Pfaff basename, dirname: Improve documentation. * doc/posix-functions/basename.texi: Mention dirname module and base_name() function. * doc/posix-functions/dirname.texi: Mention dir_name() and mdir_name() functions. Suggested by Werner LEMBERG . 2014-09-24 Jim Meyering exclude: declare exclude_patopts static * lib/exclude.c (exclude_patopts): Declare static, to avoid triggering a -Wmissing-prototypes warning. The alternative (declaring it in the .h file) would require publicizing the private "struct patopts". 2014-09-21 Werner Lemberg dirname: support compilation with C++ * lib/dirname.h: Add necessary C linkage declarations. 2014-09-16 Paul Eggert qsort_r: include Problem reported by Tom G. Christensen in: http://lists.gnu.org/r/bug-gnulib/2014-09/msg00071.html * lib/qsort.c [!_LIBC]: Include first. 2014-09-16 Dylan Cali avltree-list: avoid compiler warnings (trivial) * lib/gl_anytree_list2.h: Add _GL_ATTRIBUTE_PURE to avoid -Werror=suggest-attribute=pure. * lib/gl_array_list.c: Likewise. * lib/gl_avltree_list.c (gl_avltree_list_check_invariants): Add extern declaration to avoid -Werror=missing-prototypes. This is not added to a header as only exported for tests. Add (void) to the check_invariants() call to indicate we're discarding the result in this context which avoids -Werror=unused-value. Note we don't use ignore_value here to avoid a dependency as we know we'll not be adding __attribute__((warn_unused_result)) to check_invariants(). Add _GL_ATTRIBUTE_CONST to avoid -Werror=suggest-attribute=const. 2014-09-15 Paul Eggert qsort_r: new module, for GNU-style qsort_r * m4/qsort_r.m4: New file. Forgot to add this earlier. 2014-09-15 Werner LEMBERG strerror_r-posix: support compilation with C++ * lib/strerror_r.c: Add necessary C linkage declarations. 2014-09-11 Johannes Zarl fcntl-h: fix compilation with Intel C++ compiler (trivial) * lib/fcntl.in.h: ICC has the same issue as GCC <= 4.2. 2014-09-09 Fridolin Pokorny mountlist: use /proc/self/mountinfo when available Use libmount to propagate device IDs provided by Linux in /proc/self/mountinfo. This will give more accurate output when using df in chroot'ed environments as the device IDs are not determined by stat() which may be inaccurate within the chroot. * lib/mountlist.c (read_file_system_list): Use the libmount routines from util-linux to parse "/proc/self/mountinfo" or fall back to standard getmntent() processing. * m4/ls-mntd-fs.m4: Check for libmount only when 1-argument getmntent() is used, as is the case on GNU/Linux. 2014-09-07 Eric Wong users.txt: add cmogstored cmogstored has used gnulib since the beginning in 2012 to support GNU/Linux, FreeBSD, and GNU/kFreeBSD. 2014-09-05 Mathieu Anquetin Trivial change. * gnulib-tool: Use same options as build-aux/bootstrap to download PO files. 2014-09-05 Mathieu Anquetin Trivial change. * gnulib-tool: Fallback to wget when rsync of PO files fails. 2014-09-04 Eric Blake maintainer-makefile: add syntax check for useless ';;' * top/maint.mk (sc_prohibit_double_semicolon): New rule. 2014-09-04 Paul Eggert pthread, pthread_sigmask, threadlib: port to Ubuntu 14.04 Problem reported by Assaf Gordon in: http://lists.gnu.org/r/bug-gnulib/2014-09/msg00023.html Apparently Ubuntu is doing some fancy link-time optimization that doesn't work with -lpthread but does work with -pthread. Work around the bug by preferring -pthread to -lpthread. * m4/pthread.m4 (gl_PTHREAD_CHECK): * m4/threadlib.m4 (gl_THREADLIB_BODY): Prefer -pthread to -lpthread. * m4/pthread_sigmask.m4 (gl_FUNC_PTHREAD_SIGMASK): Treat -pthread like -lpthread. 2014-09-04 Eric Blake error: drop spurious semicolon * lib/error.c (__error_at_line): Fix ';;'. 2014-09-02 Paul Eggert gnulib-common.m4: port to GCC 4.2.1 and Sun Studio 12 C++ * m4/gnulib-common.m4 (AC_C_RESTRICT): Override AC_C_RESTRICT unconditionally. Update from autoconf, incorporating: 2014-09-02 autoconf: port 'restrict' to GCC 4.2.1 2009-01-28 Fix AC_C_RESTRICT for Sun Studio 12 C++. 2014-09-01 Paul Eggert manywarnings: add GCC 4.9 warnings Also, make it easier to maintain this in the future. * build-aux/gcc-warning.spec: Add -Wabi-tag, -Wconditionally-supported, -Wdelete-incomplete, -Winherited-variadic-ctor, -Wvirtual-move-assign, -Wzerotrip. Remove duplicates. Use tabs uniformly, as that's what 'cut' wants. * m4/manywarnings.m4 (gl_MANYWARN_ALL_GCC): Add -Wdate-time, -Wopenmp-simd. Use -fdiagnostics-show-option and -funit-at-a-time only for older GCC versions that need them. Handle -Wnormalized=nfc specially, so that the 'comm' command used for maintenance doesn't get confused. 2014-08-31 Paul Eggert vasnprintf: fix bugs in width computation * lib/vasnprintf.c (VASNPRINTF): Rework previous change, which introduced a bug, to avoid the warning in a different way. Avoid undefined behavior if the width arg is less than -INT_MAX. Avoid unnecessary use of HAS_WIDTH local. 2014-08-31 Thien-Thi Nguyen (tiny change) vasnprintf: Avoid signed/unsigned comparison warning. * lib/vasnprintf.c (VASNPRINTF): To calculate padding, compare end addr of generated string w/ maximum end addr. 2013-08-30 Mats Erik Andersson (tiny change) parse-datetime: Avoid pointer difference. * lib/parse-datetime.y (yylex): Compare pointer to end of buffer, instead of calculating difference of pointers. This removes an annoying warning, devoid of any use. 2014-08-29 Paul Eggert qsort_r: new module, for GNU-style qsort_r This works even on FreeBSD, which has an incompatible qsort_r API. * MODULES.html.sh: Add it. * doc/glibc-functions/qsort_r.texi: It's now supported. * lib/qsort.c: New file, taken from glibc with minor changes inside "#ifndef _LIBC" and with an unnecessary "#include " removed. * lib/qsort_r.c: New file, compiled only on FreeBSD. * lib/stdlib.in.h (qsort_r): Declare in the usual way. * m4/stdlib_h.m4 (gl_STDLIB_H_DEFAULTS): * modules/qsort_r, modules/qsort_r-tests: New files. * modules/stdlib (Makefile): Set up its defaults. * tests/test-qsort_r.c: New file. 2014-08-08 Paul Eggert vla: new module GNU RCS can use this, mostly for documentation I expect. See: http://lists.gnu.org/r/bug-gnulib/2014-08/msg00025.html * MODULES.html.sh: Add vla. * lib/vla.h, modules/vla: New files. 2014-08-07 Daiki Ueno localename: make gl_locale_name_thread really thread-safe on Windows * lib/localename.c [WINDOWS_NATIVE && !IN_LIBINTL]: Include "glthread/lock.h". (get_lcid_lock) [WINDOWS_NATIVE]: New variable. (get_lcid) [WINDOWS_NATIVE]: Lock while looking for an LCID. 2014-08-07 Paul Eggert getpass: don't assume struct termios Problem report and trivial fix by Jonas 'Sortie' Termansen in: http://lists.gnu.org/r/bug-gnulib/2014-08/msg00015.html * lib/getpass.c (getpass): Port to systems lacking struct termios. getdtablesize: fall back on sysconf (_SC_OPEN_MAX) Problem reported by Jonas 'Sortie' Termansen in: http://lists.gnu.org/r/bug-gnulib/2014-08/msg00023.html * lib/getdtablesize.c (getdtablesize) [_SC_OPEN_MAX]: Implement via sysconf for platforms that lack getdtablesize. vararrays: modernize AC_C_VARARRAYS for C11 This backports a change I recently made to Autoconf. * m4/vararrays.m4 (AC_C_VARARRAYS): Define __STDC_NO_VLA__ if VLAs are not supported, as this is what C11 does. The old macro HAVE_C_VARARRAYS is still defined if they are supported, but is now obsolescent. Also, check for VLA bug in GCC 3.4.3. 2014-08-07 Alessandro Degano (tiny change) relocatable-prog-wrapper: port gettext to OS X 10.8 + GCC 4.8.1 * build-aux/install-reloc (func_create_wrapper): Also wrap strerror-override, stat, stat. 2014-08-05 Paul Eggert sys_select: fix FD_ZERO problem on Solaris 10 * lib/sys_select.in.h: Fix Solaris 10 bug where "#include " followed by "#include " caused FD_ZERO to expand to an expression that invoked memset without necessarily including . The problem was that the first include defined _SYS_TIME_H, causing the second include to short-circuit. Fix a similar problem with followed by . Also, fix what appears to be a cut-and-paste typo, by replacing _GL_SYS_SELECT_H_REDIRECT_FROM_SYS_TIME_H with _GL_SYS_SELECT_H_REDIRECT_FROM_SYS_TYPES_H. accept: document Solaris 10 type glitch * doc/posix-functions/accept.texi (accept): Mention that Solaris 10 'accept' takes void * last arg, not socklen_t *. 2014-08-04 Paul Eggert extern-inline: port to FreeBSD, DragonFly * m4/extern-inline.m4 (gl_EXTERN_INLINE): Also assume the bug is present if either __DragonFly__ or __FreeBSD__ is defined. FreeBSD problem reported by Andrey Borzenkov in: http://lists.gnu.org/r/bug-gnulib/2014-07/msg00104.html Also, worry about __APPLE__ only if __MACH__ is also defined, as this is more consistent with the rest of gnulib. (_GL_EXTERN_INLINE_STDHEADER_BUG): Rename this internal macro from _GL_EXTERN_INLINE_APPLE_BUG, since the bug is not limited to Apple. 2014-08-01 Siddhesh Poyarekar regex: Make #if/#ifdef usage consistent for DEBUG * lib/regex_internal.c: Use "#if defined DEBUG && DEBUG" instead of the inconsistent usage of #if and #ifdef as that works with both Glibc and Gnulib's style. 2014-07-31 Eric Blake openat-die: use _Noreturn markup * modules/openat-die (Depends-on): Add snippet/_Noreturn. * lib/openat-die.c (openat_save_fail, openat_restore_fail): Mark _Noreturn. 2014-07-30 Eric Blake test-open: port to cygwin, which lacks Fortify * tests/test-open.h (ALWAYS_INLINE): New macro. (__always_inline): Don't abuse internal symbol on non-glibc. 2014-07-19 Eli Zaretskii localename: Enforce declarations before statements. * localename.c (gl_locale_name_thread): Declare 'lcid' before the first statement. 2014-07-18 Jim Meyering test-userspec: don't look up numeric user names * tests/test-userspec.c: I found a system for which getpwnam("0") returned a pointer to a non-root user's entry, and that made the test fail. (T): Prefix each numeric input with "+", to inhibit lookup. 2014-07-15 Eli Zaretskii localcharset, localename: MS-Windows support for non-default locales * lib/localcharset.c (locale_charset) [WINDOWS_NATIVE]: Before falling back on the default system codepage, try extracting the codepage from what 'setlocale' returns. This allows to take into account changes of the codeset due to non-default locale set by a previous call to 'setlocale'. * lib/localename.c (LOCALE_NAME_MAX_LENGTH) [WINDOWS_NATIVE]: Define if not already defined. (enum_locales_fn, get_lcid) [WINDOWS_NATIVE]: New functions. (gl_locale_name_thread) [WINDOWS_NATIVE]: Produce the current locale by calling 'setlocale', then converting the locale name into LCID by calling 'get_lcid'. This allows to take into account changes in the current locale from the default one, in contrast to GetThreadLocale. 2014-07-14 Daiki Ueno announce-gen: avoid failure when Digest::SHA is installed When Digest::SHA is available, Digest::SHA1 is not loaded and thus Digest::SHA1->new in print_checksums fails. * build-aux/announce-gen (digest_classes): New associative array for available message digest implementations. (print_locations): Use it. 2014-07-13 Pádraig Brady gettext: revert "update macros to version 0.19" This reverts commit 9b9370ca, as it currently requires that developers of any project that explicitly uses the gettext module or implicitly uses it through the utimens-tests or futimens-tests modules, use gettext >= 0.19. However there are some stability and availablity issues with that version at present. We can reinstate this soon, when stability is addressed and packages are more readily available. 2014-07-12 Jim Meyering regex: don't deref NULL upon heap allocation failure * lib/regcomp.c (parse_dup_op): Handle duplicate_tree failure in one more place. To trigger the segfault, configure grep -with-included-regex, build it, and run these commands: ( ulimit -v 300000; echo a|src/grep -E a+++++++++++++++++++++ ) I discovered this while replying to a private report from Jens Schleusener about excessive memory consumption by grep when using a regular expression like the one above. 2014-07-11 Paul Eggert regex: fix memory leak in compiler Fix by Andreas Schwab in: https://sourceware.org/ml/libc-alpha/2014-06/msg00503.html * lib/regcomp.c (parse_reg_exp): Deallocate partially constructed tree before returning error. 2014-07-10 Assaf Gordon announce-gen: avoid perl warnings * build-aux/announce-gen: add two minor checks to avoid "use of uninitialized value" warnings when command-line parameters are missing. 2014-07-10 Assaf Gordon localename: avoid -Wsuggest-attribute={const,pure} warnings * lib/localename.c (string_has): Tag internal function as pure. * lib/localename.h (gl_locale_name_default): Tag extern declaration as const when appropriate. 2014-07-10 Eli Zaretskii nl_langinfo: Fix last change. * lib/nl_langinfo.c (includes): Drop redundant include. 2014-07-10 Siddhesh Poyarekar error: Fix -Wundef warnings in glibc * lib/error.c [_LIBC]: Define default macros for glibc. (print_errno_message) [defined HAVE_STRERROR_R || _LIBC]: Check _LIBC before STRERROR_R_CHAR_P. error: Sync from glibc master * lib/error.c [_LIBC]: Remove INTUSE usage. (error_tail): Remove unused macro ALLOCA_LIMIT. Fix potential buffer overflow. Fix potential NULL dereference in strcmp. 2014-07-09 Pavel Hrdina (tiny change) nl_langinfo: fix build under mingw * lib/nl_langinfo.c (includes): Pick up for GetACP(). 2014-07-09 Andrew D Warshall mountlist: do not classify a bind-mounted dir entry as "dummy" * m4/ls-mntd-fs.m4: Check for hasmntopt() on platforms with 1-argument getmntent() (instead of assuming absence). 2014-07-08 Eric Blake maint.mk: less syntax-check noise when SIGPIPE is ignored * top/maint.mk (_sc_header_without_use) (sc_require_config_h_first): Parse full list. 2014-07-07 Eli Zaretskii Paul Eggert nl_langinfo: CODESET on MS-Windows and more items from localeconv * lib/langinfo.in.h (DECIMAL_POINT, THOUSANDS_SEP, GROUPING) (CURRENCY_SYMBOL, INT_CURR_SYMBOL, MON_DECIMAL_POINT) (MON_THOUSANDS_SEP, MON_GROUPING, POSITIVE_SIGN, NEGATIVE_SIGN) (FRAC_DIGITS, INT_FRAC_DIGITS, P_CS_PRECEDES, N_CS_PRECEDES) (P_SEP_BY_SPACE, N_SEP_BY_SPACE, P_SIGN_POSN, N_SIGN_POSN): Define. * lib/nl_langinfo.c: Include and early. Include if Microsoft Windows. Include if !REPLACE_NL_LANGINFO. (ctype_codeset): New function, taken from rpl_nl_langinfo, and with improvements for Microsoft Windows. (rpl_nl_langinfo): Use it. (nl_langinfo) [!REPLACE_NL_LANGINFO]: Likewise. Compute the values of RADIXCHAR, THOUSEP, GROUPING, CRNCYSTR, INT_CURR_SYMBOL, MON_DECIMAL_POINT, MON_THOUSANDS_SEP, MON_GROUPING, POSITIVE_SIGN, NEGATIVE_SIGN, FRAC_DIGITS, INT_FRAC_DIGITS, P_CS_PRECEDES, N_CS_PRECEDES, P_SEP_BY_SPACE, N_SEP_BY_SPACE, P_SIGN_POSN, and N_SIGN_POSN from the corresponding values returned by 'localeconv'. Compute the values of AM_STR, PM_STR, DAY_n, ABDAY_n, MON_n, and ABMON_n by calling 'strftime' with a suitable struct tm value. 2014-07-05 Paul Eggert Bruno Haible has stepped down as maintainer.

Let's hope someone volunteers. 2014-06-27 Paul Eggert mktime: merge #if/#ifdef usage from glibc * lib/mktime.c: Use "#if defined DEBUG && DEBUG", not "#if DEBUG", as that works with both Glibc's and Gnulib's style. See thread starting at Siddhesh Poyarekar's bug report at: http://lists.gnu.org/r/bug-gnulib/2014-06/msg00102.html 2014-06-20 Alfred M. Szmidt git-version-gen: improve option descriptions * build-aux/git-version-gen: Mention that --prefix and --fallback have a mandatory argument. 2014-06-19 Paul Eggert regex: fix memory leak in compiler Fix by Andreas Schwab in: https://sourceware.org/ml/libc-alpha/2014-06/msg00462.html * lib/regcomp.c (parse_expression): Deallocate partially constructed tree before returning error. regex: merge patch from libc 2014-02-12 Joseph Myers Combine __USE_BSD and __USE_SVID into __USE_MISC. * lib/regex.h [__USE_BSD]: Change condition to [__USE_MISC]. 2014-06-17 Paul Eggert acl: port to gcc -Wredundant-decls From a request by Dmitry Antipov in: http://lists.gnu.org/r/emacs-devel/2014-06/msg00263.html * lib/acl.h (_GL_ACL_H): New macro. Protect entire contents with "#ifndef _GL_ACL_H". 2014-06-11 Bruce Korb Jim Meyering parse-duration: eliminate 68-year duration limit * lib/parse-duration.c: Include "intprops.h". (TIME_MAX): Rename to MAX_DURATION and define to TYPE_MAXIMUM(time_t). * modules/parse-duration (Depends-on): Add intprops. Reported by Jonas 'Sortie' Termansen. 2014-06-14 Paul Eggert pthread: don't assume AC_CANONICAL_HOST, port better to Solaris, etc. * modules/pthread (Depends-on): Add 'extensions', as it defines _POSIX_PTHREAD_SEMANTICS, which is needed on Solaris. (configure.ac-early): New section. * m4/pthread.m4 (gl_PTHREAD_CHECK): Revert previous change, as it is no longer needed. 2014-06-14 Pádraig Brady pthread: define thread-safe macros on some platforms * m4/pthread.m4 (gl_PTHREAD_CHECK): Define macros needed for thread-safe operation on some platforms. 2014-06-13 Paul Eggert regex: don't be multithreaded if USE_UNLOCKED_IO. Problem reported by Michael Felt in: http://bugs.gnu.org/17773 * lib/regex_internal.h: Do not use multithreaded version if USE_UNLOCKED_IO is defined. This is a hack, but it works around a porting bug with coreutils 8.22 on AIX 7.1. 2014-06-11 Daiki Ueno gettext: update macros to version 0.19 * m4/intl.m4, m4/po.m4: Update from gettext-0.19. In particular, depend on gl_EXTERN_INLINE and drop support for older Bison versions. 2014-06-10 Pádraig Brady select,poll: fix console handle check on windows 8 lib/poll.c (IsConsoleHandle): Change from testing the lower 2 bits of the handle to the more expensive but accurate syscall. lib/select.c: Likewise. 2014-06-10 Eli Zaretskii select: fix waiting on anonymous pipes on MS-Windows * lib/select.c (rpl_select): Fall back to polling when select() indicates there is nothing to check, while due to the timeout not expiring, activity is indicated on one of the handles. Also clear the TIMEOUT argument if the timer does expire. 2014-06-10 Eli Zaretskii times: fix to return non constant value on MS-Windows * lib/times.c (times): Don't use the process creation time, rather clock() which on windows returns the number of clock ticks since the process started. 2014-06-09 Michael Goffioul isatty: fix to work on windows 8 * lib/isatty.c (IsConsoleHandle): Change from testing the lower 2 bits of the handle to the more expensive but accurate syscall. 2014-06-07 Paul Eggert maint: fix typo in fdl.texi * doc/fdl.texi: Fix typo (missing '@'). Somehow this was in fdl.texi but not fdl-1.3.texi. 2014-06-06 Ben Walton mountlist: avoid hasmntopt const type warning on solaris * lib/mountlist.c: Solaris defines the OPT param of hasmntopt() with char * instead of const char *. Passing the constant string "ignore" generates a compiler warning. For Solaris cast MNT_IGNORE to avoid the warning. 2014-06-04 Eric Blake maintainer-makefile: delete obsolete code * top/maint.mk (build_aux): Drop old code, as threatened. maintainer-makefile: avoid spurious error messages * top/maint.mk (syntax-check): Guard definition and use of $(shell) by whether Makefile is present. 2014-06-03 Ben Walton rename: avoid unused-but-set-variable compiler warning * lib/rename.c (rpl_rename): In the non-Win32 variant of rpl_rename, it is possible that dst_exists may be set but not used. Mark it with the unused attribute to avoid compiler warnings. 2014-06-02 Ben Walton rename: mark a label as potentially unused * lib/rename.c (rpl_rename): Avoid compiler warnings seen on Solaris, by marking the out label as potentially unused. * m4/gnulib-common.m4: Mention the need for the trailing ; for C++. 2014-06-01 Paul Eggert gnulib-common.m4: Fix typo in _GL_UNUSED_LABEL. * m4/gnulib-common.m4 (_GL_UNUSED_LABEL): Omit trailing semicolon. 2014-06-02 Ben Walton acl: apply pure attribute to two functions * lib/acl-internal.h (acl_nontrivial, acl_ace_nontrivial): Mark as "pure" as flagged by gcc 4.9 on Solaris 10. 2014-06-01 Pádraig Brady gnulib-common.m4: add _GL_UNUSED_LABEL * m4/gnulib-common.m4: Add _GL_UNUSED_LABEL which is similar to _GL_UNUSED, but handles g++ < 4.5 not supporting this syntax. 2014-05-31 Paul Eggert dup2, fcntl, fcntl-h: port to AIX 7.1 This fixes some porting problems discovered when testing the latest grep snapshot on AIX 7.1. I don't think if fixes any bugs in grep but it could be important for other applications. * doc/posix-functions/dup2.texi: * doc/posix-functions/fcntl.texi: * doc/posix-headers/fcntl.texi: Document AIX bugs. * lib/fcntl.in.h (O_CLOEXEC, O_NOFOLLOW, O_TTY_INIT) [_AIX]: Define to 0 if outside 'int' range. * m4/dup2.m4 (gl_FUNC_DUP2): * m4/fcntl.m4 (gl_FUNC_FCNTL): Check for getdtablesize. If it's available, test a value just outside its range instead of testing 1000000. When cross-compiling, guess that AIX will fail this improved test. 2014-05-30 Paul Eggert printf, config.rpath: Port to FreeBSD 10. Problem reported by Tijl Coosemans in: http://lists.gnu.org/r/bug-gnulib/2014-05/msg00078.html * build-aux/config.rpath (hardcode_libdir_flag_spec) (hardcode_direct): Simplify FreeBSD configuration. (library_names_spec): Don't mishandle FreeBSD 10+. * m4/printf.m4 (gl_PRINTF_SIZES_C99, gl_PRINTF_LONG_DOUBLE) (gl_PRINTF_INFINITE_LONG_DOUBLE, gl_PRINTF_DIRECTIVE_F) (gl_SNPRINTF_TRUNCATION_C99, gl_SNPRINTF_RETVAL_C99) (gl_SNPRINTF_DIRECTIVE_N, gl_VSNPRINTF_ZEROSIZE_C99): Don't mishandle FreeBSD 10+ when cross-compiling. ftoastr: work around compiler bug in IBM xlc 12.1 * lib/ftoastr.h (_GL_FLT_PREC_BOUND, _GL_DBL_PREC_BOUND) (_GL_LDBL_PREC_BOUND): Make these macros, not enums, to work around a compiler bug in IBM xlc 12.1.0.0: it complains '"ftoastr.c", line 80.37: 1506-045 (S) Undeclared identifier _GL_FLT_PREC_BOUND.' 2014-05-30 Kieran Colford valgrind-tests: fixed misleading help message * m4/valgrind-tests.m4: The help message generated by configure implied that valgrind was disabled by default, which it wasn't. Adjusted the help message using s/enable/disable/ to clarify. 2014-05-30 Ulrich Weigand isfinite, isinf, isnan tests: fix for little-endian PowerPC * tests/test-isfinite.c (test_isfinitel): Only manipulate the first double of a PowerPC "double double" pair. * tests/test-isinf.c (test_isinfl): Likewise. * tests/test-isnan.c (test_long_double): Likewise. * tests/test-isnanl.h (main): Likewise. * tests/test-signbit.c (test_signbitl): Likewise. 2014-05-29 Paul Eggert exclude-tests: port to AIX 7.1 * modules/exclude-tests (test_exclude_LDADD): Add $(LIBTHREAD). Needed on AIX 7.1 with xlc V12.1, otherwise it won't link because the regex code uses locks. 2014-05-28 Paul Eggert pthread_sigmask, timer-time: use gl_THREADLIB only if needed Without this fix, Emacs would sometimes call sigprocmask instead of pthread_sigmask, which is a no-no in multithreaded applications. Problem reported by Jorgen Schaefer in . * m4/pthread_sigmask.m4 (gl_FUNC_PTHREAD_SIGMASK): Suppress check for pthread_sigmask working without -lpthread if the application always links with -lpthread. Do not link with $LIBMULTITHREAD if gl_THREADLIB is not defined. * m4/timer_time.m4 (gl_TIMER_TIME): Require gl_THREADLIB only if it is defined. Do not append $LIBMULTITHREAD to LIB_TIMER_TIME if gl_THREADLIB is not defined. 2014-05-27 Sylvain Beucler . gnulib-tool: wget translations using --no-verbose rather than --quiet This allows the user to see error messages if any (--quiet hides them) * gnulib-tool: Invoke wget with --no-verbose, rather than --quiet. 2014-05-27 Sylvain Beucler gnulib-tool: adjust translation wget to avoid a https redirection Context: http://translationproject.org/latest/gnulib redirects to https://translationproject.org/latest/gnulib/ Rationale: if the user falls back to wget, she doesn't have rsync and is probably in a minimal build environment, where packages such as 'ca-certificates' are missing as well, resulting in a failed (and difficult to detect since ignored) translation initial fetch. Consequently let's avoid https if possible, and add the missing trailing slash. This also avoids an unnecessary 302 redirection. * gnulib-tool: Add trailing slash to gnulib URL. 2014-05-22 Pádraig Brady getlogin_r-tests: check return value rather than errno * tests/test-getlogin_r.c (main): As per POSIX we should be verifying the return value from getlogin_r() rather than errno. 2014-05-22 Pádraig Brady getlogin_r-tests: fix various issues in recent change * tests/test-getlogin_r.c: Include required headers that were missed in recent commit eec20b4e. Also consistently check the errno rather than the return value from getlogin_r as POSIX only specifies that non zero is returned on error. * modules/getlogin_r-tests (configure.ac): Add the check for ttyname(). 2014-05-21 Paul Eggert fchdir: port 'open' and 'close' redefinitions to AIX 7.1 * lib/chown.c, lib/clean-temp.c, lib/copy-file.c, lib/execute.c: * lib/fsusage.c, lib/gc-gnulib.c, lib/javacomp.c, lib/mountlist.c: * lib/openat-proc.c, lib/pagealign_alloc.c, lib/progreloc.c: * lib/spawn-pipe.c: Do not #undef 'open' and 'close'. AIX 7 does '#define open open64' and then 'int open64(const char *, int, ...);', which means the declaration for 'open' gets lost if we later '#undef open'. Discovered while building grep pretest 2.18.151-1c770 on AIX 7.1, where the compilation reported the non-fatal error "In function 'openat_proc_name' ... warning: implicit declaration of function 'open'". In this case the error is relatively harmless, but in other cases it might not be so minor. 2014-05-20 Paul Eggert xalloc: don't potentially generate invalid code for xmemdup calls * lib/xalloc.h (xmemdup): Do not mark with _GL_ATTRIBUTE_ALLOC, as this function can initialize the newly-allocated storage with new pointers, which means this function is not malloc-like. See: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=56955 2014-05-19 Pádraig Brady getlogin_r-tests: avoid false failure under sudo/ssh etc. * tests/test-getlogin_r.c (main): Sync up with test-getlogin.c changes from commit 97249cf29 to not depend on environment variables. 2014-05-18 Pádraig Brady getlogin-tests: avoid false failure under cron * tests/test-getlogin.c (main): Avoid verifying errnos from ttyname() since that's not what's under test. Centos 6 was seen to return EINVAL for ttyname() when run from cron. 2014-05-16 Jim Meyering mbrtowc.m4: fix a comment typo * m4/mbrtowc.m4 (gl_FUNC_MBRTOWC): Fix typo s/2/-2/ in emitted documentation string. 2014-05-16 Paul Eggert mbrlen, mbrtowc: fix bug with empty input * lib/mbrtowc.c (rpl_mbrtowc) [MBRTOWC_EMPTY_INPUT_BUG]: Fix the bug. * m4/mbrlen.m4 (gl_MBRLEN_EMPTY_INPUT): New macro. It's not used, so this is mainly for documentation. * m4/mbrtowc.m4 (gl_MBRTOWC_EMPTY_INPUT): New macro. (gl_FUNC_MBRTOWC): Use it. * tests/test-mbrtowc.c (main): Test for the bug. 2014-05-15 Paul Eggert doc: document mbrtowc and mbrlen problem with empty input * doc/posix-functions/mbrlen.texi (mbrlen): * doc/posix-functions/mbrtowc.texi (mbrtowc): Document portability problem when the input string is empty. See: https://sourceware.org/bugzilla/show_bug.cgi?id=16950 doc: document exec* = spawn+exit bug with non-Cygwin Windows platforms Problem reported by Eli Zaretskii in: http://lists.gnu.org/r/bug-grep/2014-05/msg00118.html * doc/posix-functions/execl.texi (execl): * doc/posix-functions/execle.texi (execle): * doc/posix-functions/execlp.texi (execlp): * doc/posix-functions/execv.texi (execv): * doc/posix-functions/execve.texi (execve): * doc/posix-functions/execvp.texi (execvp): Mention spawn+exit problem on non-Cygwin Windows platforms. 2014-05-14 Guilherme de Almeida Suckevicz getlogin-tests: avoid false failure under sudo/ssh etc. * modules/getlogin-tests (configure.ac): Check for ttyname(). * tests/test-getlogin.c (main): Don't depend on environment variables to correlate with getlogin(), since sudo and ssh etc. can tamper with the LOGNAME and USER env vars. Instead lookup the name from the uid associated with the stdin tty. 2014-05-11 Paul Eggert mbsstr, quotearg, xstrtol: pacify IRIX 6.5 cc These were found when building the latest grep snapshot on IRIX 6.5. * lib/mbsstr.c (knuth_morris_pratt_multibyte): Break "a=b=c;" into "b=c; a=b;", since IRIX 6.5 cc complains about the former if b is never used later. * lib/quotearg.c (quoting_options_from_style): * lib/xstrtol.c (__xstrtol): Use enum instead of 0, to pacify IRIX 6.5 cc. 2014-04-18 Pádraig Brady gitlog-to-changelog: revert inclusion of git-log-fix file * build-aux/git-log-fix: Delete dummy file. * modules/gitlog-to-changelog: Don't reference (overwrite) the project specific git-log-fix file. 2014-04-18 Assaf Gordon maint.mk: Relax the copyright check to cater for non FSF projects * top/maint.mk (sc_copyright_check): Relax the check for $PACKAGE.texi to not require the "Free" suffix after the copyright years. 2014-04-18 Natanael Copa physmem: use sysinfo on linux-gnu if _SC_PHYS_PAGES unavailable * lib/physmem.c (physmem_total): Some systems like musl libc don't yet support _SC_PHYS_PAGES. Use the linux syscall sysinfo as fallback if _SC_PHYS_PAGES or _SC_PAGESIZE fails. (physmem_available): Likewise for _SC_AVPHYS_PAGES. 2014-04-18 Paul Eggert exclude: port to strict C99 Strict C does not allow converting a function pointer to void * and vice versa. Pass a pointer to a function pointer instead. * lib/exclude.c (add_exclude_file): Pass the address of the function pointer. (call_addfn): And deference the address here, to match. 2014-04-17 Paul Eggert regex: do not depend on malloc-gnu * modules/regex (Depends-on): Remove malloc-gnu. It's no longer needed, because of the 2012-12-29 patch "regex: port to hosts where malloc (0) == NULL". Reported by Nathan Kennedy in: http://lists.gnu.org/r/bug-gnulib/2014-04/msg00026.html 2014-04-16 Assaf Gordon expl: avoid incorrect expl(small_value) on OpenBSD 5.4 * m4/expl.m4 (gl_FUNC_EXPL): Add a check for this condition. * doc/posix-functions/expl.texi: Mention the workaround. 2014-04-12 Paul Eggert xalloc: allow x2nrealloc (P, PN, S) where P && !*PN * lib/xalloc.h (x2nrealloc): Extend slightly, to allow the current size to be zero even when the pointer is nonnull. This accommodates the use case where P is malloc (0) and *PN is 0 on a host where malloc (0) yields nonnull. 2014-04-09 Eric Blake fts: avoid unnecessary strlen calls * lib/fts.c (_D_EXACT_NAMLEN): Restore definition when needed. 2014-04-09 Paul Eggert fts: avoid unnecessary strlen calls * lib/fts.c (fts_build): Go back to using _D_EXECT_NAMLEN when that can be faster than strlen. 2014-03-26 Bernhard Voelker fts: avoid unnecessary strlen calls * lib/fts.c (_D_EXACT_NAMLEN): Remove macro. (fts_build): Store the length of the dp->d_name entry in a local variable instead of calling strlen() several times via the above, removed macro. For 'rm -rf some-dir' with e.g. 1M directory entries, this speeds up the run by ~4%, yet this reduces the execution time by about a third if run via "ltrace -c rm -rf some-dir". 2014-03-27 Paul Eggert obstack: Remove ancient NeXTSTEP gcc support conditional This change will ease merging with glibc. The "#if ... __NEXT__" causes a warning with -Wundef which glibc now enables by default. Problem reported by Will Newton in . glibc now uses __extension__ for GCC 2.8 or later, so go with that. * lib/obstack.h (__extension__): 2014-03-27 Paul Eggert obstack: merge with glibc changes * lib/obstack.c, lib/obstack.h: Merge from glibc. This is mostly indenting and commentary changes. Instances of 'register' have been removed. 2014-03-26 Bernhard Voelker strftime: wrap macros in "do {...} while(0)" * lib/strftime.c (DO_NUMBER): Wrap multi-statement code block of this macro in "do {...} while(0)" to prevent false use as a single statement, e.g., in an un-braced "{}" else-block. (DO_SIGNED_NUMBER, DO_TZ_OFFSET, DO_NUMBER_SPACEPAD): Likewise. (strftime_case_): Remove 'else' after 'goto' - which was the only non-fatal, un-braced use of one of the above macros. Spotted by coverity (NESTING_INDENT_MISMATCH). 2014-03-26 Bernhard Voelker modechange: avoid memory leaks for invalid octal modes * lib/modechange.c (mode_compile): During the parsing of notations like +40, free the 'mc' buffer for invalid mode strings like +17777 (greater than the maximum octal mode), =18 (bad octal mode characters) or u=1 ('affected' with octal modes). Reproducer, e.g.: $ valgrind --leak-check=full chmod +17777 file Introduced via the 2012-03-09 commit, 4730c3e3, "modechange: add notations +40, 00440, etc.". Spotted by coverity (RESOURCE_LEAK). 2014-03-24 Paul Eggert gitlog-to-changelog: include a dummy git-log-fix file Problem reported by Nathan Stratton Treadway in: http://lists.gnu.org/r/bug-tar/2014-03/msg00082.html * build-aux/git-log-fix: New file. 2014-03-13 Jim Meyering gitlog-to-changelog: also include the file, git-log-fix * modules/gitlog-to-changelog (Files): Add git-log-fix. Reported by Assaf Gordon. 2014-03-06 Paul Eggert regex: port to OS X 10.8.5 en_US.UTF-8 locale This fixes a bug when ignoring case and when comparing the titlecase letter 'Lj' (U+01C8 LATIN CAPITAL LETTER L WITH SMALL LETTER J) to the corresponding uppercase letter 'LJ' (U+01C7 LATIN CAPITAL LETTER LJ). In the OS X 10.8.5 en_US.UTF-8 locale, the titlecase letter is neither lowercase nor uppercase, but uppercasing the titlecase letter (via towupper) yields the uppercase letter, so the two letters should match when ignoring case. Problem reported by Jim Meyering in . * lib/regex_internal.c (build_wcs_upper_buffer, build_upper_buffer): Don't test whether a character is lowercase before uppercasing it. 2014-03-04 Kevin Cernekee stdint, read-file: fix missing SIZE_MAX on Android (tiny change) This is basically one of the options Bruno Haible proposed in: http://lists.gnu.org/r/bug-gnulib/2012-01/msg00282.html * lib/sys_types.in.h (_GL_INCLUDING_UNISTD_H): New macro. * lib/stdint.in.h: Use it. * modules/stdint (Depends-on): Add sys_types. 2014-02-26 Pádraig Brady parse-datetime: fix crash or infloop in TZ="" parsing * lib/parse-datetime.y (parse_datetime): Break out of the TZ="" parsing loop once the second significant " is found. Also skip over any subsequent whitespace to be consistent with the non TZ= case. * tests/test-parse-datetime.c: Add test cases for TZ="" parsing. 2014-02-26 Paul Eggert savedir: new symbol for fast-read version * lib/savedir.h (SAVEDIR_SORT_FASTREAD): New symbol, for programs like GNU cp that want to use SAVEDIR_SORT_INODE if available, SAVEDIR_SORT_NONE otherwise. Problem reported by Bernhard Voelker in: http://lists.gnu.org/r/coreutils/2014-02/msg00037.html 2014-02-25 Paul Eggert unistd: port readlink to Mac OS X 10.3.9 * lib/unistd.in.h (_GL_INCLUDING_UNISTD_H): New macro, to work around self-include problem in Mac OS X 10.3.9 when combined with readlink module. Problem reported by Klaus Zietler in . 2014-02-23 Paul Eggert diffseq: remove TOO_EXPENSIVE heuristic Problem with diffutils reported by Vincent Lefevre in . The simplest solution is to remove the TOO_EXPENSIVE heuristic that I added to GNU diff in 1993. Although appropriate for circa-1993 hardware, these days the heuristic seems to be more trouble than it's worth. * lib/diffseq.h: Modernize citations. (struct context): Remove member too_expensive. All uses changed. (struct partition): Remove members lo_minimal, hi_minimal. All uses changed. (diag, compareseq): Remove arg find_minimal. All uses changed. (diag): Remove the TOO_EXPENSIVE heuristic that I added back in 1993 to make 'diff' run faster (but not as well) on large inputs. These days, computers are fast enough that it's typically better to run slower but more accurately. * lib/fstrcmp.c: Remove duplicate comment. * lib/fstrcmp.c (strcmp_bounded): * lib/git-merge-changelog.c (compute_differences): Adjust to diffseq.h changes. * NEWS: Document the change. savedir: simplify by using stpcpy * lib/savedir.c (direntry_t): Remove size member. All uses removed. (streamsavedir): Use stpcpy instead. * modules/savedir (Depends-on): Add stpcpy. 2014-02-21 Pádraig Brady spawn: fix link error on uclibc * m4/spawn_h.m4 (gl_HAVE_POSIX_SPAWN): use AC_SEARCH_LIBS, to incorporate -lrt if needed (on uclibc for example). * modules/posix_spawn: Reference the substituted LIB. 2014-02-21 Thomas Petazzoni (tiny change) timer: fix uClibc detection of threading * m4/time_time.m4 (gl_TIMER_TIME): Detect whether threads are enabled in uClibc. 2014-02-21 Eric Blake maintainer-makefiles: provide AC_PROG_SED for older autoconf * m4/gnulib-common.m4 (AC_PROG_SED): Copy from newer autoconf. 2014-02-21 Sergey Poznyakoff exclude: add support for posix regexps This commit adds support for POSIX extended regular expressions and fixes a long-standing memory leak (pattern buffer was never freed). It also implements a new interface function to read exclude patterns from a FILE, which passes an additional parameter to its callback function, thereby allowing to preserve its state between invocations. * lib/exclude.c (struct patopts): Pack regex and pattern into union. (pattern_buffer): New struct. (exclude): New member patbuf. (exclude_add_pattern_buffer): New function. (free_exclude_segment): Free regexps. (free_exclude): Free allocated pattern buffers. (exclude_patopts): New function. (file_pattern_matches): Use exclude_patopts. (add_exclude): support regexps. (add_exclude_fp): New function. (add_exclude_file): Rewrite using add_exclude_fp. (fnmatch_pattern_has_wildcards): Support posix extended regexps. * lib/exclude.h (EXCLUDE_REGEX, EXCLUDE_ALLOC): New flags. (add_exclude_fp) (add_exclude_file): Rewrite using add_exclude_fp. (fnmatch_pattern_has_wildcards): Support posix extended regexps. * lib/exclude.h (EXCLUDE_REGEX, EXCLUDE_ALLOC): New flags. (add_exclude_fp) (exclude_add_pattern_buffer): New prototypes. * modules/exclude: Depends on regex and filename. 2014-02-20 Eric Blake maintainer-makefiles: use $(SED) for syntax check * modules/maintainer-makefile (configure.ac): Check for sane sed. * top/maint.mk: Change sed to $(SED). 2014-02-11 Sergey Poznyakoff Paul Eggert savedir: add sorting arg to savedir, streamsavedir; remove fdsavedir Patch based on an idea by Dick Streefland in . * NEWS: Document this. * lib/savedir.c (NAME_SIZE_DEFAULT): Remove. (direntry_t, comparison_function): New types. (direntry_cmp_name): New function. (direntry_cmp_inode) [D_INO_IN_DIRENT]: New function. (streamsavedir, savedir): New arg OPTION. (streamsavedir): Simplify memory allocation. (fdsavedir): Remove. * lib/savedir.h (enum savedir_option): New type. (streamsavedir, savedir): New arg OPTION. (fdsavedir): Remove. 2014-02-05 Paul Eggert file-type: add support for doors and other less-common file types Problem with S_ISDOOR reported by Rich Burridge. * lib/file-type.c (file_type): Do S_ISLNK early too. Do S_TYPEIS* macros before the rest. Add S_ISCTG, S_ISDOOR, S_ISMPB, S_ISMPC, S_ISMPX, S_ISNAM, S_ISNWK, S_ISOFD, S_ISOFL, S_ISPORT, S_ISWHT. 2014-01-23 Eric Blake pthread: work around winpthread header pollution on mingw * lib/time.in.h: Move pthread workarounds... * lib/pthread.in.h: ...here. * m4/pthread.m4 (gl_PTHREAD_CHECK): Also build pthread.h when we detect macro pollution on mingw. * doc/posix-headers/pthread.texi (pthread.h): Document the problems. 2014-01-22 Paul Eggert qacl: check for fchmod * m4/acl.m4 (gl_FUNC_ACL): Check for fchmod, since acl-internal.h and qset-acl.c both use HAVE_FCHMOD. 2014-01-20 Paul Eggert fdopen-tests: port to Tru64 * tests/test-fdopen.c (main): Don't invoke fdopen on a file descriptor that is not open, as POSIX doesn't specify the resulting behavior and the test does not work on Tru64. Problem reported by Steven M. Schweda in: http://lists.gnu.org/r/bug-gnulib/2014-01/msg00079.html stdalign: port to HP-UX compilers * lib/stdalign.in.h (_Alignas): Use __attribute__ (__aligned__ (x)) if __HP_cc or __HP_aCC are nonzero. 2014-01-16 Paul Eggert strtoimax: port to platforms lacking 'long long' VMS's pre-C99 compiler lacks 'long long', so 'configure' doesn't check whether strtoll is declared, which causes the C file to wrongly report an error. Problem reported by Steven M. Schweda in: http://lists.gnu.org/r/bug-diffutils/2014-01/msg00003.html * lib/strtoimax.c (strtoull): Declare only if HAVE_UNSIGNED_LONG_LONG_INT. (strtoll): Declare only if HAVE_LONG_LONG_INT. 2014-01-16 Daniel Albers (tiny change) relocatable-perl: fix texi syntax * doc/relocatable-maint.texi: Escape braces. 2014-01-09 Reuben Thomas relocatable-perl: like relocatable-script, but for Perl scripts * build-aux/relocatable.pl.in: Add. * doc/relocatable-maint.texi: Add documentation. * modules/relocatable-perl: Add. 2014-01-07 Paul Eggert tests: fix export bug in previous patch Problem reported by Jim Meyering. * tests/init.sh (re_shell): New var, which is exported instead of re_shell_. tests: simplify porting to Solaris 10 /bin/sh Some test cases in 'grep' need a shell that groks '$('; export re_shell_ for their benefit. Problem reported for 'grep' by Dagobert Michelsen in . * tests/init.sh (re_shell_): Export if it's used. 2014-01-06 Eric Blake md5, sha1, sha256, sha512: support older autoconf * m4/00gnulib.m4 (m4_divert_push): Wrap diversion stack for autoconf < 2.63b. include_next: port to autoconf 2.63 * m4/gnulib-common.m4 (AS_VAR_COPY): Define if missing. 2014-01-04 Jim Meyering maint: add a gnulib-local rule to keep non-ascii out of .texi files * cfg.mk (sc_keep_gnulib_texi_files_mostly_ascii): New rule, so that "make sc_maint" will ding anyone who puts non-ascii in any of gnulib's .texi files. 2014-01-03 Jim Meyering freadable, fwritable, fwriting: declare with the "pure" attribute * lib/freadable.h (freadable): Declare with the "pure" attribute. * lib/fwritable.h (fwritable): Likewise. * lib/fwriting.h (fwriting): Likewise. Suggested by Bruno Haible. maint.mk: adapt openat.h-include-without-use test * top/maint.mk (sc_prohibit_openat_without_use): Also check for FCHMODAT_INLINE, FCHOWNAT_INLINE and STATAT_INLINE, to avoid failing on gnulib's own lib/{chmod,chown,stat}at.c files. With this change, running "make sc_maint" in gnulib's top-level directory now passes for me. 2014-01-03 Paul Eggert doc: use ASCII in .texi files where UTF-8 isn't needed * doc/posix-functions/crypt.texi, doc/posix-functions/encrypt.texi: * doc/posix-functions/setkey.texi, doc/regex.texi: Use ASCII input, not UTF-8. 2014-01-02 Jim Meyering freading: declare with the "pure" attribute * lib/freading.h (freading): Declare with the "pure" attribute. manywarnings: remove -Wmudflap * m4/manywarnings.m4 (gl_MANYWARN_ALL_GCC): Remove -Wmudflap, since it is no longer supported in gcc-4.9-to-be. 2014-01-01 Paul Eggert relocatable-script: remove unused code Problem reported by Reuben Thomas in: http://lists.gnu.org/r/bug-gnulib/2013-12/msg00117.html * build-aux/relocatable.sh.in (func_tmpdir): Remove unused function. 2014-01-01 Jim Meyering maint: fix public-submodule-commit to work with newer git * top/maint.mk (public-submodule-commit): Remove excess quoting. We were over-quoting the test arguments, and somewhere prior to version 1.8.5.2.229, git stopped removing those excess quotes, which made the test fail, since the unexpanded strings would always differ; using GIT_TRACE=1 confirmed that the git merge-base command wasn't even being run. 2014-01-01 Paul Eggert doc: update main copyright year * doc/gnulib.texi: Update copyright date. 2014-01-01 Eric Blake version-etc: new year * lib/version-etc.c (COPYRIGHT_YEAR): Bump to 2014. * all files: run 'make update-copyright' 2013-12-24 Eric Blake passfd: give nicer error for recvfd at eof * lib/passfd.c (recvfd): Fake ENOTCONN if other end closes early. * tests/test-passfd.c (main): Enhance test to cover this. 2013-12-17 Paul Eggert gettimeofday: port recent C++ fix to Emacs Without this further patch, Emacs won't build due to the portcheck failing. Also, this simplifies the patch a bit. * lib/time.in.h (localtime, gmtime): Don't replace unless GNULIB_GETTIMEOFDAY. Treat them more like mktime. * lib/time.in.h (localtime, gmtime): * m4/gettimeofday.m4 (gl_GETTIMEOFDAY_REPLACE_LOCALTIME): * m4/time_h.m4 (gl_HEADER_TIME_H_DEFAULTS): * modules/time (time.h): Don't worry about the possibility of localtime and gmtime being absent; they're present in all C libraries we know about. * m4/time_h.m4 (gl_HEADER_TIME_H_DEFAULTS): Don't assume sys_time is present and has been initialized. Instead, use a hack that should work even if it hasn't been. Don't use a portcheck for gmtime or localtime; this supports the hack. * modules/time (time.h): Substitute GNULIB_GETTIMEOFDAY. 2013-12-17 John W. Eaton gettimeofday: fix C++ crosscompilation Never replace gmtime and localtime by macros when compiling with C++, this prevents from being included. * m4/gettimeofday.m4 (gl_GETTIMEOFDAY_REPLACE_LOCALTIME): Do not define gmtime and localtime as preprocessor macros. Instead define some HAVE_GMTIME, HAVE_LOCALTIME, REPLACE_GMTIME, and REPLACE_LOCALTIME substitutions. * lib/time.in.h: Declare gmtime and localtime when needed. * m4/time_h.m4 (gl_HEADER_TIME_H_DEFAULTS): AC_SUBST HAVE_GMTIME, HAVE_LOCALTIME, REPLACE_GMTIME, and REPLACE_LOCALTIME. * modules/time: Depend on gettimeofday, and substitute the above variables in time.h. 2013-12-17 Paul Eggert qacl: port to Windows better See Eli Zaretskii in . * lib/file-has-acl.c (acl_access_nontrivial): Return -1 and set errno if !HAVE_ACL_FIRST_ENTRY && !HAVE_ACL_TO_SHORT_TEXT && !HAVE_ACL_FREE_TEXT. 2013-12-12 Alexander V. Lukyanov md5, sha1, sha256, sha512: fix (trivial) compile error in c++ mode. * lib/gl_openssl.h: Cast void pointers to a specific type. 2013-12-07 Pádraig Brady open-tests: fix build failure with -Werror=old-style-declaration * tests/test-open.h: Reorder the inline to avoid the issue. 2013-12-07 Pádraig Brady md5, sha1, sha256, sha512: fix link error with partial libcrypto * m4/gl-openssl.m4 (gl_CRYPTO_CHECK): Only clear LIB_CRYPTO at init time, so that if early checks find crypto routines, while the last does not, then @LIB_CRYPTO@ is replaced correctly, avoiding link failures. 2013-12-07 Paul Eggert md5, sha1, sha256, sha512: add gl_SET_CRYPTO_CHECK_DEFAULT This provides a new way to specify the default for gl_CRYPTO_CHECK, one that is reflected in the --help message. Emacs uses this, as well as the old way. This attempts to implement a suggestion by Pádraig Brady in . * m4/gl-openssl.m4(gl_SET_CRYPTO_CHECK_DEFAULT): New macro. (gl_CRYPTO_CHECK): Use it. Mention the default in --help output. md5, sha1, sha256, sha512: add 'auto', and a way to specify default * m4/gl-openssl.m4 (gl_CRYPTO_CHECK): Add support for a new option, --with-openssl=auto, which causes the library to be used if available and silently ignored if not. Add support to allow configure.ac to specify its own default, by setting with_openssl_default before invoking gl_INIT. 2013-12-05 Paul Eggert open-tests: port to glibc with _FORTIFY_SOURCE and -O1 Problem reported by Daiki Ueno in: http://lists.gnu.org/r/bug-gnulib/2013-06/msg00052.html * tests/test-open.h (__always_inline): New macro, if not already defined. (test_open): Use it. 2013-12-04 Eric Blake include_next: minimize code duplication * modules/include_next (Depends-on): Add absolute-header. * m4/include_next.m4 (gl_NEXT_HEADERS_INTERNAL): Reuse gl_ABSOLUTE_HEADER_ONE instead of open-coding it. 2013-12-04 Pádraig Brady getcwd: fix compile error in configure check * m4/getcwd-abort-bug.m4 (gl_FUNC_GETCWD_ABORT_BUG): Include errno.h 2013-12-04 Pádraig Brady regex: suppress core dumps from detection code * m4/regex.m4 (gl_REGEX): Catch the SIGABRT and convert to SIGTERM to suppress core dumps that may well occur on glibc systems. These core dumps might not be cleaned up automatically, or could trigger some system core dump handling logic. 2013-12-03 Pádraig Brady md5, sha1, sha256, sha512: support mandating use of openssl * m4/gl-openssl.m4 (gl_crypto_check): Adjust the --with-openssl description, to list the now 3 separate options. also don't mention the default=no, since this is implicit given the option is described as --with-openssl rather than --without-openssl. If projects change the default they're free to document that. with --with-openssl[=yes] we now error out when the specified hash algorithm is not available in libcrypto. 2013-12-03 Ivailo test-xvasprintf: (trivial) fix to disable some -Wformat-security diags * tests/test-xvasprintf.c: Disable -Wformat-zero-length and -Wformat-nonliteral checks, as these edge cases are part of the test. 2013-12-03 Eric Blake regex: avoid glibc deadlock during configure * m4/regex.m4 (gl_REGEX): Avoid recursive malloc deadlock when glibc bug 15078 in turn triggers bug 16159. Reported by Michal Privoznik. 2013-12-02 Pádraig Brady md5, sha1, sha256, sha512: use openssl routines if available. --with-openssl the libcrypto md5, sha1, sha224, sha256, sha384, sha256 routines will be used if available, requiring apps to link @LIB_CRYPTO@ * lib/gl_openssl.h: Provide wrappers for specified openssl hash. * m4/gl-openssl.m4 (gl_CRYPTO_CHECK): New function to lookup libcrypto in the standard system location. * m4/sha1.m4: Call gl_CRYPTO_CHECK() for SHA1. * m4/sha256.m4: Likewise with SHA256. * m4/sha512.m4: Likewise with SHA512. * m4/md5.m4: Likewise with MD5. * m4/gc.m4: Ensure @LIB_CRYPTO@ set for tests. * lib/sha1.h: Include wrappers if HAVE_OPENSSL_SHA1. * lib/sha256.h: Likewise with SHA256. * lib/sha512.h: Likewise with SHA512. * lib/md5.h: Likewise with MD5. * lib/sha1.c: Exlude functionality if HAVE_OPENSSL_SHA1. * lib/sha256.c: Likewise with SHA256. * lib/sha512.c: Likewise with SHA512. * lib/md5.c: Likewise with MD5. * modules/crypto/sha1 (Link:): Add the new optional lib.

Reported by Eric Blake in . Change the comment to try to explain this better. 2013-11-27 Pádraig Brady selinux-h: improve stub types and add more stub functions * lib/se-selinux.in.h: Change security_context_t to a typedef rather than a define, as it's a pointer type and so is better as a typedef to avoid issues declaring multiple variables with the comma operator. Also add stub for string_to_security_class(). * lib/se-context.in.h: Add stub functions for context_{type,range,role,user}_get(). 2013-11-27 Paul Eggert ignore-value: prefer GCC version back through 2.0 The code didn't match the comments, so I did a bit of software archaeology. GCC 2.0 seems to support __extension__ and __typeof__, so fix both code and comments to use 2.0. * lib/ignore-value.h (ignore_value): Use __extension__ and __typeof__ for GCC 2.0 through 3.3, too. 2013-11-25 Mats Erik Andersson pty: Activate the signature wrapper of forkpty. The intended preprocessor macro HAVE_FORKPTY is never defined, yet `lib/forkpty.c' depends on it. * m4/pty.m4 (gl_FUNC_FORKPTY): At completed analysis, apply AC_DEFINE_UNQUOTED to HAVE_FORKPTY with value $HAVE_FORKPTY for access to wrapper in `lib/forkpty.c'. 2013-11-18 Jim Meyering and Paul Eggert quotearg: don't attempt to store 1 << 31 into an "int" * lib/quotearg.c (quotearg_buffer_restyled): Building coreutils with gcc's new -fsanitize=undefined and running its tests triggered some new test failures due to undefined behavior, all with this diagnostic: lib/quotearg.c:629:62: runtime error: left shift of 1 by 31 places \ cannot be represented in type int Rather than shifting "1" left to form a mask, shift the bits right and simply use "1" as the mask. 2013-11-21 Paul Eggert error: depend on stdio Problem reported by Nikos Mavrogiannopoulos in * modules/error (Depends-on): Add stdio. 2013-11-18 Ben Pfaff * doc/relocatable-maint.texi (Supporting Relocation): Improve wording. Reported by Reuben Thomas . 2013-11-13 Paul Eggert * lib/getgroups.c (posix_getgroups, getgroups) [__APPLE__]: New function and macro, to work around _DARWIN_C_SOURCE problem. Reported by Jack Howarth in . 2013-11-11 Pádraig Brady base64: provide a fast path for encoding well sized buffers Avoid conditionals in the base64 encoding loop, which was seen to give 60% better throughput. * lib/base64.c (base64_encode_fast): A new function to be called when we don't want to NUL terminate, and we have enough space in the output to encode the given input. (base64_encode): Call the _fast() version when appropriate. Also remove a redundant mask with 0x3F on the first encoded byte. 2013-11-08 Paul Eggert extern-inline: port better to OS X 10.9 * m4/extern-inline.m4: Omit serial number; this file doesn't use them. (gl_EXTERN_INLINE): Do not suppress the use of extern inline on OS X 10.9, except for g++ where the bug is still present. See . 2013-11-08 Eric Blake fpending: fix regression on DragonFly BSD * m4/fpending.m4 (gl_FUNC_FPENDING): Check for declaration. * lib/fpending.h (__fpending): Don't declare twice. Reported by GW in 2013-11-05 Jim Meyering hash: relax license to LGPLv2+, for libguestfs * modules/hash (License): Change from GPL to LGPLv2+. 2013-11-03 Paul Eggert intprops: port to Oracle Studio c99 * lib/intprops.h (_GL_HAVE___TYPEOF__) [__SUNPRO_C && __STDC__]: Define to 0, to avoid diagnostics when Oracle Studio is pedantic. 2013-10-31 Paul Eggert obstack: pacify HP C * lib/obstack.h (obstack_free) [!__GNUC__]: Rewrite to avoid warning "conversion from pointer to smaller integer" from HP C-ANSI-C - cc version B9007AA/B3910B A.06.26. It's safe to assume C89 or later nowadays, so cast to void instead of int. Privately reported by H.Merijn Brand. Also, change header to match glibc's, to make checking against glibc easier. 2013-10-29 Jim Meyering maint.mk: prefer gpgv2 over gpgv * top/maint.mk (gpgv): Use gpgv2 if present, else gpgv. (gpg_key_ID): Use $(gpgv), rather than hard-coding "gpgv". Reported by Gary Vaughan. 2013-10-30 Paul Eggert isnan: port to VAX Reported by John Klos for NetBSD-5/VAX in . * lib/isnan.c (IEEE_FLOATING_POINT): New macro, stolen from Emacs. (FUNC): Use it. 2013-10-28 Jim Meyering gnulib-tool: protect against CDPATH * gnulib-tool: Many "cd" built-in functions print a directory name to stdout when CDPATH is set, e.g., $ bash -c 'CDPATH=/; cd tmp' /tmp Unset it, when possible. Prompted by a comment from Bruce Korb. maint.mk: restore functionality removed by recent change... Sunday's change, v0.0-8062-g6b24f60, may have appeared correct from the context of a shallow-cloned gnulib repository: "git describe" would fail in such a directory. However, that change made it so the reported gnulib revision no longer includes the version number or a commit count, even when run from a full clone. * top/maint.mk (gnulib-version): Use the full "git describe" output when possible, e.g., the form above, rather than the abbreviated, no-tag, no-commit-count string, and fall back to using a 10-byte hash, rather than the default minimal-length hash prefix, since while the minimal-length one may be fine today, it is likely not to be unique for very long. 2013-10-26 Jim Meyering maint.mk: fix "release" target to build _version This fixes a bug in README-release whereby following the outlined steps, one would publish a tarball whose programs would report --version output not consistent with the package version number. This bug caused grep-2.15 to produce a grep program whose --version option made it print 2.14.56-1e3d rather than 2.15. * top/maint.mk (release): Making this target build "_version" ensures that the new version number is reflected in configure. 2013-10-21 Ben Pfaff install-reloc: Support multi-binary installation. * build-aux/install-reloc: Support installing multiple programs in one invocation, as done by Automake starting with commit 4295fe33eb23f (Multi-file install for PROGRAMS.).

Problem reported by Daniel Richard G. in . * lib/mgetgroups.c (mgetgroups): Don't call realloc (NULL, 0). * modules/mgetgroups (Depends-on): Depend on realloc-posix, not realloc-gnu. 2013-10-12 Paul Eggert regex-tests: port to HP-UX 11.11 Problem reported by Daniel Richard G. in . * modules/regex-tests (test_regex_LDADD): Add LIBTHREAD, LIB_PTHREAD. 2013-10-10 Paul Eggert verify: document some 'assume' pitfalls * doc/verify.texi (Compile-time Assertions): Mention that 'assume (E)' can sometimes slow things down.

Don't include verify.h: it's no longer needed, as types wider than 64 bits are now supported. (COUNT_ONE_BITS_GENERIC): New macro. (popcount_supported) [_MSC_VER]: New inline function. (COUNT_ONE_BITS): Use it. New arg MSC_BUILTIN, for better performance with MSC. All uses changed.

Problem reported by Mike Miller in . * tests/test-sys_select.c, tests/test-sys_time.c (verify_tv_sec_type): Allow platforms like 64-bit OpenBSD where timeval's tv_sec is wider than time_t. 2013-08-09 Pádraig Brady bootstrap: support checksum utils having -c but not --status * build-aux/bootstrap: Only look for sha1sum if updating po files. Add sha1 to the list of supported checksum utils since it's now supported through adjustments below. (update_po_files): Remove the use of --status in a way that will suppress all error messages, but since this is only used to minimize updates, it shouldn't cause an issue. Exit early if there is a problem updating the po file checksums. (find_tool): Remove the check for --version support as this is optional as per commit 86186b17. Don't even check for the presence of the command as if that is needed, it's supported through configuring prerequisites in bootstrap.conf. Prompt that when a tool isn't found, one can define an environment variable to add to the hardcoded search list. 2013-08-05 Jim Meyering regex: port to non-glibc/lock-using systems Since 29-05-2013 commit, 55ba71f4, compilation on a non-glibc system with GNULIB_LOCK would fail due to absence of the included "glthread/lock.h". This would affect any package for which the "lock" module is used only by the regex module, and not explicitly used. * m4/regex.m4 (gl_PREREQ_REGEX): Require gl_GLIBC21. * modules/regex (Depends-on) [!GLIBC && $ac_use_included_regex]: Add a dependency on the "lock" module. 2013-07-20 Daiki Ueno localecharset: make locale_charset thread-safe on Mac OS X * lib/localcharset.c (locale_charset) [DARWIN7]: Use MB_CUR_MAX_L instead of MB_CUR_MAX. 2013-07-20 Daiki Ueno gettext: update to version 0.18.3 * m4/intl.m4, m4/po.m4: Update from gettext-0.18.3. In particular, require AC_PROG_SED to allow user to specify custom sed command when generating en@quot PO file. 2013-07-18 Werner Lemberg (tiny change) bootstrap: use correct source when copying build-aux files * build-aux/bootstrap (gnulib_extra_files): This variable is relative to upstream gnulib layout, not downstream. 2013-07-17 Paul Eggert tmpdir: fix bug in VMS port * lib/tmpdir.c (path_search) [__VMS]: Never add slash. See Steven M. Schweda in . 2013-07-15 Paul Eggert tmpdir: port to VMS, to // != /, and to long dirs * lib/tmpdir.c (__libc_secure_getenv) [!_LIBC]: Rename from __secure_getenv, so that we're more like the glibc version. All uses changed. (path_search): Don't put slash after directory if __VMS. Problem reported by Steven M. Schweda in . Simplify code to add slash; no need for a loop. Do not remove trailing slash from "//". Do not assume dlen <= INT_MAX. 2013-07-09 Paul Eggert regex: port to --with-included-regex --enable-gcc-warnings non-threaded * lib/regex_internal.h (lock_fini, lock_lock): Rework to avoid gcc warnings in the non-threaded case. Reported by Charlie Brown in . accept4, dup3, pipe2: port to Cygwin Problem reported for Emacs by Ken Brown in . * lib/accept4.c (accept4) [O_BINARY]: * lib/dup3.c (dup3) [O_BINARY]: * lib/pipe2.c (pipe2) [O_BINARY]: Use set_binary_mode, not setmode. * lib/pipe2.c [!GNULIB_BINARY_IO]: Include binary-io.h. * modules/binary-io (Depends-on): Remove module indicator. These last two bits undo the previous change to pipe2 and binary-io. 2013-07-09 Pádraig Brady mountlist: add support for deallocating returned list entries * lib/mountlist.c (free_mount_entry): A new exported function to deallocate a mount list entry. (read_file_system_list): Refactor to use the new deallocation function. Suggested by Anton Ovchinnikov. 2013-07-07 Paul Eggert stdalign, verify: port to FreeBSD 9.1, to C11, and to C++11 Problem reported by Ulrich Mueller in . * lib/stdalign.in.h (_Alignas, _Alignof): Port to FreeBSD 9.1, and to C11 and C++11. (_Alignas): Also support ICC. * lib/verify.h (_Static_assert): Undef if defines it. * m4/stdalign.m4 (gl_STDALIGN_H): Port to ICC and to C++11. 2013-07-06 Paul Eggert fnmatch: don't goto over declaration * lib/fnmatch_loop.c (FCT): Hoist local up one level, to avoid undefined behavior for goto over a declaration. Problem reported by Charlie Brown in . pipe2: decouple from binary-io a bit This is for Emacs, which needs pipe2 but not binary-io. * lib/pipe2.c [!GNULIB_BINARY_IO]: Don't include binary-io.h. * modules/binary-io (Depends-on): Add module indicator. 2013-07-03 Eric Blake mgetgroups: relax license to LGPLv2+ * modules/getugroups (License): Change from GPLv3+. * modules/mgetgroups (License): Likewise. * modules/getgroups (License): Change from LGPLv3+. xalloc-oversized: relax license to LGPLv2+ * modules/xalloc-oversized (License): Change from GPLv3+. nproc: relax license to LGPLv2+ * modules/nproc (License): Change from LGPLv3+. bootstrap: honor --no-git * build-aux/bootstrap: Don't even try to use git when user is pointing to a static checkout. 2013-06-23 Paul Eggert ignore-value: port to gcc -pedantic * lib/ignore-value.h (ignore_value): Port to gcc -pedantic, by using __extension__. Reindent as per usual gnulib style nowadays. Simplify GCC version check. 2013-06-21 Paul Eggert extern-inline: port to gcc -std=c89 * m4/extern-inline.m4 (gl_EXTERN_INLINE): Do not use __gnu_inline__ if pedantic and pre-C99. 2013-06-18 Paul Eggert doc: document extern-inline * doc/extern-inline.texi: New file. * doc/gnulib.texi (alloca-opt): Include it. * m4/extern-inline.m4: Move some comments to documentation, and others closer to what they describe. doc: chatter less * doc/Makefile (NEWEST_GNULIB_TEXI_FILE): New macro. (updated-stamp): Use it. This causes 'make' to output just one file name rather than zillions. fflush, fseeko: port to musl cross-compiles * lib/fseeko.c (fseeko): Assume that fflushing stdin works if on some implementation that (1) is not known to be buggy, (2) claims conformance to POSIX.1-2008 or later, and (3) is being cross-compiled to so we can't easily check for lack of conformance. This is for cross-compiling to musl. Reported by Rich Felker in . * m4/fclose.m4 (gl_FUNC_FCLOSE): * m4/fflush.m4 (gl_FUNC_FFLUSH): * m4/fseeko.m4 (gl_FUNC_FSEEKO): Adjust to above change. * m4/fflush.m4 (gl_FUNC_FFLUSH_STDIN): Set gl_cv_func_fflush_stdin to 'cross', not to 'no', when cross-compiling. AC_DEFINE FUNC_FFLUSH_STDIN to 1, 0, -1 if fflushing stdin is known to work, known not to work, or unknown. 2013-06-15 Paul Eggert msvc-inval: port to mingw-w64 * lib/msvc-inval.c (gl_msvc_invalid_parameter_handler): Use __cdecl, not cdecl, for mingw-w64. Reported by LRN in . 2013-06-11 Paul Eggert getcwd-lgpl: port to Tru64 * lib/getcwd-lgpl.c: Include , for malloc etc. Problem reported by Steven M. Schweda in . tests: port large-fd POSIX spawn tests to OS X Problem reported by Daiki Ueno in . * tests/test-posix_spawn_file_actions_addclose.c: * tests/test-posix_spawn_file_actions_adddup2.c: * tests/test-posix_spawn_file_actions_addopen.c: Include , for OPEN_MAX, if available. (big_fd): New static function. (main): Use it. 2013-06-04 Bernhard Voelker tests/nap.h: use an adaptive delay to avoid ctime update issues The recent change in nap.h (5191133e) decreased the probability of lost races to about a third, however such problems could still be observed in virtual machines and openSUSE's OBS. Before, nap() detected the needed time once empirically and then used that delay (together with a small correction multiplier) in further calls. This problem has been reported and discussed several times, including guesses about possible kernel issues: https://lists.gnu.org/r/bug-gnulib/2013-04/msg00071.html http://lists.gnu.org/r/coreutils/2012-03/msg00088.html https://lists.gnu.org/r/bug-gnulib/2011-11/msg00226.html http://bugs.gnu.org/12820 https://lists.gnu.org/r/bug-gnulib/2010-11/msg00113.html https://lists.gnu.org/r/bug-gnulib/2009-11/msg00007.html Now, nap() avoids the race alltogether by verifying on a reference file whether a timestamp difference has happened. * tests/nap.h (nap_fd): Define file descriptor variable for the witness file. (nap_works): Change return value to bool. Change passing the old file's status by value instead of by reference as this function does no longer update that timestamp; rename the function argument from st to old_st. Remove the local variables cdiff and mdiff because that function now returns true/false instead of the precise delay. (guess_delay): Remove function. (clear_tmp_file): Add new function to close and unlink the witness file. (nap): Instead of re-using the delay which has been calculated during the first call, avoid the race by actually verifying that a timestamp difference can be observed on the current file system. Use an adaptive approach for the delay to minimize execution time. Assert that the maximum delay is <= ~2 seconds, more precisely sum(2^n) from 0 to 30 = 2^31 - 1 = 2.1s. Use atexit to call clear_tmp_file when the process terminates. 2013-06-02 Paul Eggert sig2str: port to C++ * lib/sig2str.h (sig2str, str2sig): Declare as extern "C". Reported by Daniel J Sebald in . 2013-05-30 Eric Blake docs: mention cygwin shortcoming in * doc/posix-headers/sys_un.texi (sys/un.h): Mention problem. vasnprintf: silence mingw compiler warning * lib/vasnprintf.c (VASNPRINTF): Avoid unused variable warning. 2013-05-29 Paul Eggert c-ctype, regex, verify: port to gcc -std=c90 -pedantic Avoid constructions that are rejected by gcc -std=c90 -pedantic. This fixes a porting bug I recently reintroduced in regex, and some other instances that I discovered while testing the fix. * lib/c-ctype.h [__STRICT_ANSI__]: Avoid ({ ... }). * lib/regcomp.c (utf8_sb_map) [__STRICT_ANSI__]: Avoid [0 ... N] = E. * lib/regex_internal.h [!_LIBC && GNULIB_LOCK]: Do not use a macro with an empty argument if this is a pedantic pre-C99 GCC. * lib/verify.h: Do not use _Static_assert if this is a pedantic pre-C11 GCC. regex: adapt to locking regime instead of depending on pthread Instead of depending on pthread, adapt to whatever thread modules are in use. Problem reported by Ludovic Courtès in and by Mats Erik Andersson in . * lib/regex_internal.h (lock_define, lock_init, lock_fini): Support either the 'lock' module, or the 'pthread' module, or no module. (lock_lock, lock_unlock): New macros. * lib/regexec.c (regexec, re_search_stub): Use the new macros. * modules/lock, modules/pthread (configure.ac): Add module indicator. * modules/regex (Depends-on): Remove pthread. 2013-05-22 Eric Blake getgroups: document portability issues * doc/glibc-functions/initgroups.texi (initgroups): Mention multithread safety. * doc/posix-functions/getpwuid.texi (getpwuid): Likewise. * doc/posix-functions/getpwuid_r.texi (getpwuid_r): Likewise. * doc/glibc-functions/getgrouplist.texi (getgrouplist): Mention getugroups. * doc/posix-functions/getgroups.texi (getgroups): Mention multithread safety and mgetgroups. 2013-05-22 Bernhard Voelker test-lchown, test-chown: also skip test if chown fails with EPERM * tests/test-lchown.h (test_lchown): Add EPERM to the condition to skip this test, to handle FAT file systems. * tests/test-chown.h (test_chown): Likewise. 2013-05-19 Paul Eggert regex: fix dfa race in multithreaded uses Problem reported by Ludovic Courtès in . * lib/regex_internal.h (lock_define, lock_init, lock_fini): New macros. All uses of __libc_lock_define, __libc_lock_init changed to use the first two of these. (__libc_lock_lock, __libc_lock_unlock): New macros, for non-glibc platforms. (struct re_dfa_t): Define the lock unconditionally. * lib/regexec.c (regexec, re_search_stub): Remove some now-incorrect '#ifdef _LIBC"s. * modules/regex (Depends-on): Add pthread, if we use the included regex. * lib/regcomp.c: Do actions that are not needed for glibc, but may be needed elsewhere. (regfree, re_compile_internal): Destroy the lock. (re_compile_internal): Check for lock-initialization failure. malloca: port to compilers that reject size-zero arrays This fixes a bug introduced in my previous patch. * lib/malloca.c (struct preliminary_header): Use an int rather than a character array of size int; that's simpler. (struct header): Remove, replacing with ... (union header): New type. This avoids the need for declaring a character array of size zero, which is not allowed on some platforms. All uses changed. 2013-05-18 Paul Eggert parse-datetime, tests: don't use "string" + int Recent versions of 'clang' complain about C source code that uses expressions of the form '"string literal" + integer', I guess on the theory that it's confusing for readers who are used to C++. On those grounds I suppose it's OK to make this minor style change. * lib/parse-datetime.y (parse_datetime): * tests/test-fchdir.c (main): * tests/test-snprintf-posix.h (test_function): * tests/test-snprintf.c (main): * tests/test-vasnprintf-posix.c (test_function): * tests/test-vasnprintf.c (test_function): * tests/test-vsnprintf.c (main): * tests/unistdio/test-ulc-asnprintf1.h (test_function): Rewrite '"str" + E' to '&"str"[E]'. 2013-05-17 Alexandre Duret-Lutz argmatch: port to C++ * lib/argmatch.h [__cplusplus]: Add extern "C". argp: typo fix * lib/argp-help.c: Typo in comment. 2013-05-15 Paul Eggert manywarnings: update for GCC 4.8.0 * m4/manywarnings.m4 (gl_MANYWARN_ALL_GCC): Add -Waggressive-loop-optimizations, -Wreturn-local-addr, which are new to GCC 4.8. Remove -Wformat=2, -Wmissing-format-attribute, -Wmissing-noreturn, as they are duplicates of other warnings. Remove -Wunreachable-code, as it is removed in GCC 4.8 and was documented to be flaky in earlier versions of GCC. spawn-tests, sys_socket-tests, sys_wait-tests: port to clang * tests/test-spawn.c (main): * tests/test-sys_socket.c (main): * tests/test-sys_wait.c (main): Don't have a switch value that isn't covered by a case. getaddrinfo-tests: port --enable-gcc-warnings to clang * tests/test-getaddrinfo.c (simple): Avoid casts from looser to stricter-aligned pointers. thread: port --enable-gcc-warnings to clang * lib/glthread/thread.h [__clang__ && USE_POSIX_THREADS_WEAK]: Include , to pacify a warning about pthread_sigmask. stdio: use __REDIRECT for fwrite, fwrite_unlocked * lib/stdio.in.h (fwrite): When working around bug 11959, use __REDIRECT rather than '#define fwrite(...) ... fwrite (...) ...'. This is a more-targeted way to fix the -Wunused-value issue with clang, and it works with GCC too. Problem with targeting reported by Eric Blake in . (fwrite_unlocked): Treat like fwrite. I ran into this issue while debugging the fwrite issue. stdio: port --enable-gcc-warnings to clang * lib/stdio.in.h (fwrite) [__clang__]: Ignore -Wunused-value entirely, since the GCC workaround for fwrite does not pacify clang. sig2str: port --enable-gcc-warnings to clang * lib/sig2str.c (sig2str): Avoid warning about unused printf argument. obstack: port --enable-gcc-warnings to clang * lib/obstack.h (obstack_ptr_grow_fast, obstack_int_grow_fast): Avoid casts from looser to stricter-aligned pointers. memchr2: port --enable-gcc-warnings to clang * lib/memchr2.c (memchr2): Avoid casts from looser to stricter-aligned pointers. mbsstr: port --enable-gcc-warnings to clang * lib/mbsstr.c (knuth_morris_pratt_multibyte): Avoid casts from looser to stricter-aligned pointers. malloca: port --enable-gcc-warnings to clang * lib/malloca.c (struct header): New member 'magic', to avoid casts. (mmalloca): Avoid casts from looser to stricter-aligned pointers. inttostr: port --enable-gcc-warnings to clang * lib/anytostr.c [__clang__]: Ignore -Wtautological-compare. warnings: port to clang Problem reported by Daniel P. Berrange via Eric Blake in . * m4/warnings.m4 (gl_UNKNOWN_WARNINGS_ARE_ERRORS): New macro. (gl_WARN_ADD): Use it. 2013-05-11 Jim Meyering quotearg: do not read beyond end of buffer * lib/quotearg.c (quotearg_buffer_restyled): Do not read beyond the end of an ARG for which no length was specified. With an N-byte quote string, (e.g., N is 3 in the fr_FR.UTF-8 locale), this function would read N-2 bytes beyond ARG's trailing NUL. This was triggered via coreutils' misc/sort-debug-keys.sh test and detected by running the test against a binary compiled with gcc-4.8.0's -fsanitize=address. * tests/test-quotearg-simple.c (main): Add a test to trigger the bug. * modules/quotearg-simple-tests (Files): Add tests/zerosize-ptr.h. Introduced via the 2000-01-15 commit, c4b7f3f8, "Quote multibyte characters correctly." 2013-05-11 Daiki Ueno lock: work around pthread recursive mutexes bug in Mac OS X 10.6 * m4/lock.m4: Don't define HAVE_PTHREAD_MUTEX_RECURSIVE if the compilation target is Mac OS X 10.6. Problem reported by parafin and Andoni Morales in and . 2013-05-11 Paul Eggert mkdir-p: remove assumptions about umask and mode * lib/mkdir-p.c (make_dir_parents): Do not assume that the current umask is 0, or that MODE is a subset of MODE_BITS. 2013-05-10 Eric Blake maint.mk: catch more abuse of HAVE_DECL in syntax-check * top/maint.mk (sc_prohibit_defined_have_decl_tests): Relax regex. 2013-05-10 Stefano Lattarini deps: require Automake >= 1.9.6 in generated Makefile fragments That is the same minimal version required in the DEPENDENCIES file. Moreover, the old code generated a requirement of Automake >= 1.5, and that is an insanely outdated version. * gnulib-tool: Bump minimal version requirement in AUTOMAKE_OPTIONS. * tests/havelib/rpathlx/Makefile.am: Likewise. * tests/havelib/rpathly/Makefile.am: Likewise. * tests/havelib/rpathlyx/Makefile.am: Likewise. * tests/havelib/rpathlz/Makefile.am: Likewise. * tests/havelib/rpathlzyx/Makefile.am: Likewise. * tests/havelib/rpathx/Makefile.am: Likewise. * tests/havelib/rpathy/Makefile.am: Likewise. * tests/havelib/rpathz/Makefile.am: Likewise. 2013-05-08 Eric Blake bootstrap: AC_INIT may have more than four parameters * build-aux/bootstrap (extract_package_name): Correctly extract non-empty tarname field. Avoid range in regex. Based on a report by Sami Kerola . 2013-05-07 Paul Eggert qacl: port to MS-Windows port of GNU Emacs * lib/acl-errno-valid.c (acl_errno_valid) [ENOTSUP == ENOSYS]: Omit the duplicate ENOTSUP case. Needed for the MS-Windows port of GNU Emacs. Problem reported by Eli Zaretskii in . 2013-05-07 Mike Frysinger acl: include quote.h * lib/copy-acl.c: Include quote.h. * lib/set-acl.c: Likewise. 2013-05-06 Mike Frysinger fchownat, renameat, unlinkat: update statat dependencies These modules use statat and lstatat, not fstatat; so depend on the statat module, which was split out recently from fstatat. * modules/fchownat, modules/unlinkat: Change fstatat to statat. * modules/renameat: Likewise. Also delete fstat. URL: http://bugs.gentoo.org/468790 2013-05-04 Stefano Lattarini Assume gnulib is checked out from Git, not CVS In fact, access to the gnulib repository through CVS has been disabled, or more precisely, got broken and was never restored; see: Note that support for CVS is not removed completely and unthinkingly by this change: only support for CVS checkouts of gnulib itself is removed. For example, the 'bootstrap' script still cater to .cvsingore files and CVS directories, for the benefit of those poor gnulib clients still stuck with CVS. Ditto for the 'gnulib-tool' script itself. * gnulib-tool: Simplify accordingly. * posix-modules: Likewise. * MODULES.html.sh: Likewise. * doc/gnulib.texi: No longer mention the decommissioned CVS gnulib repository. * doc/gnulib-intro.texi: Likewise. * doc/gnulib-readme.texi: Likewise. * doc/gnulib-tool.texi: In the examples and explanations, refer to a sample '.gitignore' file rather than a sample '.cvsignore'. * NEWS: Update. * m4/extensions.m4: While at it, remove a comment mistakenly referring to "CVS Autoconf" rather than "git Autoconf". 2013-04-30 Paul Eggert utimensat-tests, etc.: try to fix some races Problem reported by Bernhard Voelker in . I don't know whether this patch fixes that race condition, but it fixes *some* race conditions, so it should be a win. * modules/chown-tests (Depends-on): * modules/fchownat-tests (Depends-on): * modules/fdutimensat-tests (Depends-on): * modules/futimens-tests (Depends-on): * modules/lchown-tests (Depends-on): * modules/stat-time-tests (Depends-on): * modules/utimens-tests (Depends-on): * modules/utimensat-tests (Depends-on): Depend on nanosleep, not usleep. * modules/chown-tests (test_chown_LDADD): * modules/lchown-tests (test_lchown_LDADD): * modules/stat-time-tests (test_stat_time_LDADD): New macro. * modules/fchownat-tests (test_fchownat_LDADD): * modules/fdutimensat-tests (test_fdutimensat_LDADD): * modules/futimens-tests (test_futimens_LDADD): * modules/utimens-tests (test_utimens_LDADD): * modules/utimensat-tests (test_utimensat_LDADD): Add $(LIB_NANOSLEEP). * modules/stat-time-tests (Files): Add tests/nap.h. * tests/nap.h: Include , for INT_MAX. (lt_mtime): Remove. (diff_timespec): New function. (get_stat): Rename from get_mtime. All callers changed. (nap_works): Determine the needed delay by inspecting the file system's timestamp jumps; this should be more reliable. Look at both mtime and ctime, and take the maximum of the two jumps. (nap_works, guess_delay): Return a nanosecond count, not a microsecond count. All callers changed. (nap_works, nap): Use nanosleep, not usleep. Check for nanosleep failure. (nap): Multiply the guess by 1.125, to accommodate the case where the file system's clock is a bit slower than nanosleep's clock. * tests/test-stat-time.c (BASE): New macro. Include nap.h. (nap): Remove; nap.h now defines this. This removes a duplicate implementation of 'nap'. utimens, utimensat: work around Solaris UTIME_OMIT bug Solaris 11.1 and Solaris 10 have the same UTIME_OMIT bug that Linux kernel 2.6.32 does. Work around it in the same way. * doc/posix-functions/futimens.texi (futimens): * doc/posix-functions/utimensat.texi (utimensat): Document the bug. * lib/utimens.c (fdutimens, lutimens): * lib/utimensat.c (rpl_utimensat): Work around the bug. gettext: now it's your responsibility to add -I$(top_builddir)/intl Formerly, it was your responsibility to do this for all Makefile.ams other than Gnulib's. Now it's your responsibility to do it for Gnulib's Makefile.am, too. * NEWS: Document this. * modules/gettext (AM_CPPFLAGS): Don't append -$(top_builddir)/intl. acl: include errno.h to get errno Reported by Daiki Ueno in . * lib/copy-acl.c, lib/set-acl.c: Include errno.h. 2013-04-29 Paul Eggert tests: don't assume getdtablesize () <= 10000000 * modules/cloexec-tests: * modules/dup2-tests: * modules/dup3-tests: * modules/nonblocking-tests: * modules/posix_spawn_file_actions_addclose-tests: * modules/posix_spawn_file_actions_adddup2-tests: * modules/posix_spawn_file_actions_addopen-tests: * modules/unistd-safer-tests: Depend on the getdtablesize module. * tests/test-cloexec.c: * tests/test-dup-safer.c: * tests/test-dup2.c: * tests/test-dup3.c: * tests/test-fcntl.c: * tests/test-nonblocking.c: * tests/test-posix_spawn_file_actions_addclose.c: * tests/test-posix_spawn_file_actions_adddup2.c: * tests/test-posix_spawn_file_actions_addopen.c: Don't assume getdtablesize () <= 10000000. 2013-04-28 Paul Eggert extern-inline: work around bug in Sun c99 * m4/extern-inline.m4 (_GL_INLINE, _GL_EXTERN_INLINE): Work around bug in Sun C 5.12 c99's implementation of 'inline'. 2013-04-27 Paul Eggert qacl: new module, broken out from the acl module This is for GNU Emacs, which wants the acl functions but does not want 'error' invoked when they fail. * lib/acl-internal.h: Do not include error.h, quote.h. (ENOSYS, ENOTSUP): Remove; no longer needed. (ACL_NOT_WELL_SUPPORTED): Remove; replaced by acl_errno_valid. * lib/acl.h: Include . (acl_errno_valid): New function. * lib/copy-acl.c, lib/set-acl.c: Include errno,h, not acl-internal.h. * lib/copy-acl.c (qcopy_acl): Move to lib/qcopy-acl.c. * lib/set-acl.c: Rename from lib/set-mode-acl.c.

Add lib/set-acl.c. (Depends-on): Move extern-inline, fstat, sys_stat to qacl module. Add qacl. (configure.ac): Move gl_FUNC_ACL to qacl module. (lib_SOURCES): Remove file-has-acl.c (moved to qacl module). Rename set-mode-acl.c to set-acl.c. * lib/acl-errno-valid.c: New file. * lib/qcopy-acl.c: New file, moved from the old lib/copy-acl.c; the copy_acl function remains in copy-acl.c. * lib/qcopy-acl.c, lib/qset-acl.c: Do not include gettext.h.

Levin regex-tests, regex: allow glibc re_search behavior * tests/test-regex.c (main): In test for glibc bug 15078, reformat re_search input data to make the multi-character collating element in it clearly visible, and treat re_search return code 0 as valid. * m4/regex.m4 (gl_REGEX): Likewise. 2013-03-30 Paul Eggert stdalign: doc fix * doc/posix-headers/stdalign.texi (stdalign.h): Gnulib doesn't support '_Alignof expr'. 2013-03-29 Paul Eggert stdalign: port to stricter ISO C11 ISO C11 says that _Alignof's operand must be a parenthesized type. Problem reported by Eli Zaretskii in . * doc/posix-headers/stdalign.texi (stdalign.h): Document this. * m4/stdalign.m4 (gl_STDALIGN_H): Don't use _Alignof (expr). 2013-03-21 Paul Eggert sys_select, sys_time: port 2013-01-30 Solaris 2.6 fix to Cygwin Problem reported by Marco Atzeri in . * lib/sys_select.in.h [HAVE_SYS_SELECT_H && _CYGWIN_SYS_TIME_H]: Simply delegate to the system in this case too. Also, pay attention to _GL_SYS_SELECT_H_REDIRECT_FROM_SYS_TIME_H only if OSF/1, since otherwise Cygwin breaks, and it doesn't seem to be needed on Solaris either. * lib/sys_time.in.h [_CYGWIN_SYS_TIME_H]: Simply delegate to the system in this case. 2013-03-19 Karl Berry * build-aux/gnupload: check for erroneous (with gnupload) use of ftp-upload.gnu.org, tweak help. 2013-03-19 Paul Eggert copy-file, rpmatch: fix problems found by cppcheck Reported by Arno Onken in . * lib/rpmatch.c (try): Fix memory leak. * lib/copy-file.c: Include "ignore-value.h".

Give better diagnostics upon failure. 2013-03-13 Paul Eggert putenv: port to Solaris 10 * lib/putenv.c (_unsetenv, putenv): Use HAVE_DECL__PUTENV, not HAVE__PUTENV. Solaris 10 has a _putenv that's not declared and is not what is wanted here. * m4/putenv.m4 (gl_PREREQ_PUTENV): Check for _putenv's declaration, not for its existence. 2013-03-12 Paul Eggert mktime: fix configure typo * m4/mktime.m4 (gl_FUNC_MKTIME): Fix typo in previous change. 2013-03-12 Eric Blake regex-tests: skip UTF-8 test on mingw * modules/regex-tests (Depends-on): Add localcharset. * tests/test-regex.c (main): Use it to skip test on mingw. 2013-03-11 Eric Blake tests: make it easier to bypass alarm time in debugger * tests/test-file-has-acl.c (main): Allow gdb to override alarm. * tests/test-memmem.c (main): Likewise. * tests/test-passfd.c (main): Likewise. * tests/test-ptsname.c (main): Likewise. * tests/test-ptsname_r.c (main): Likewise. * tests/test-strcasestr.c (main): Likewise. * tests/test-strstr.c (main): Likewise. regex: port to mingw's recent addition of undeclared alarm * doc/posix-functions/alarm.texi (alarm): Document that alarm exists but still doesn't work in newer mingw. * m4/frexp.m4 (gl_FUNC_FREXP_WORKS): Check for alarm declaration, not existence.

(putenv): Fix indentation. 2013-03-11 Gary V. Vaughan unistd: don't prevent Tru64 Unix from using gnulib strtod. * lib/unistd.in.h: be careful not to include un-needed system stdlib.h from here, because that prevents gnulib stdlib.h from defining rpl_strtod correctly. 2013-03-09 Gary V. Vaughan vasprintf-posix-tests: allow rounding 1.51 to 1, per the previous changesets, but for the 'precision 0' test. * tests/test-vasprintf-posix.c (test_function): Don't insist on round-to-even, since POSIX says rounding is implementation-defined and OS X 10.8.2 rounds 1.51 to 1 here. vasprintf-posix-tests: allow rounding 1.5 to 1, per the previous changeset. * tests/test-vasprintf-posix.c (test_function): Don't insist on round-to-even, since POSIX says rounding is implementation-defined and OS X 10.8.2 rounds 1.5 to 1 here. 2013-03-08 Paul Eggert vasnprintf-posix-tests: allow rounding 1.5 to 1 * tests/test-vasnprintf-posix.c (test_function): Don't insist on round-to-even, since POSIX says rounding is implementation-defined and OS X 10.8.2 rounds 1.5 to 1 here. Reported by Gary V. Vaughan in . bootstrap: port to FreeBSD * build-aux/bootstrap (bootstrap_sync): Port sh -c usage to shells that treat '--' differently. Reported by Mats Erik Andersson in . 2013-03-08 Gary V. Vaughan regex: rename remaining __attribute calls to __attribute__. 2012-02-25 changed definition of __attribute, but left some uses unchanged, preventing compilation of regex module on most non-gcc environments. * lib/regcomp.c (re_set_fastmap, seek_collating_symbol_entry) (lookup_collation_sequence_value, build_range_exp) (build_collating_symbol): Set attributes with newly renamed __attribute__ decorator. * lib/regex_internal.c (re_string_peek_byte_case) (re_node_set_compare, re_node_set_contains): Likewise. * lib/regexec.c (acquire_init_state_context): Likewise. 2013-03-06 Bruno Haible execute: Revert last change, but use a different condition. * lib/execute.c (nonintr_close, nonintr_open): Reintroduce, but only on Windows. 2013-03-05 Eric Blake execute: drop dead code * lib/execute.c (nonintr_close, nonintr_open): Delete. 2013-03-04 Paul Eggert non-recursive-gnulib-prefix-hack: port coreutils 8.21 to HP NonStop * m4/non-recursive-gnulib-prefix-hack.m4 (gl_NON_RECURSIVE_GNULIB_PREFIX_HACK): Don't mess with ALLOCA. Problem reported for HP NonStop + coreutils 8.21 by Joachim Schmitz in . 2013-03-04 Eric Blake test-getsockopt: avoid compiler warning * tests/test-getsockopt.c (includes): Ensure close is declared. 2013-03-02 Bruno Haible sys_types: Avoid autoconf warning about gl_SYS_TYPES_H. * m4/sys_types_h.m4 (gl_SYS_TYPES_H): Define through AC_DEFUN_ONCE. 2013-03-02 Bruno Haible gettext: Update to version 0.18.2. * m4/intl.m4, m4/po.m4: Update from gettext-0.18.2. In particular: 2012-12-07 Stefano Lattarini * intl.m4, po.m4: Bump requirement in AC_PREREQ to 2.60. 2013-02-25 Paul Eggert regex: merge patches from libc 2013-02-26 Siddhesh Poyarekar * lib/regex_internal.h (__attribute__): Rename from __attribute. All uses changed. (bitset_not, bitset_merge, bitset_mask, re_string_char_size_at) (re_string_wchar_at, re_string_elem_size_at): Mark function as possibly unused. 2013-02-12 Andreas Schwab [BZ #11561] * lib/regcomp.c (parse_bracket_exp) [_LIBC]: When looking up collating elements compare against the byte sequence of it, not its name. 2013-02-21 Paul Eggert putenv: port better to native Windows * lib/putenv.c [(_WIN32 || __WIN32__) && ! __CYGWIN__]: Define WIN32_LEAN_AND_MEAN and include . (_unsetenv): Use _putenv if available. (putenv): Temporarily set NAME=' ' rather than NAME='x' as that's a bit less likely to cause damage. (putenv) [(_WIN32 || __WIN32__) && ! __CYGWIN__]: Fix the wrong value with SetEnvironmentVariable. (putenv) [!HAVE__PUTENV]: Simplify and match the HAVE__PUTENV code better. 2013-02-20 Paul Eggert regex: ignore old-style-definition warnings * lib/regex.c: Add pragma to ignore these warnings. Problem reported for GNU tar by Pavel Raiskup. 2013-02-19 Paul Eggert getcwd: support coreutils better Like strtod, getcwd incorrectly referred to HAVE_RAW_DECL_GETCWD, but this might not be correct in coreutils, which disables the raw decl checks. Problem reported by Nagendra in . * lib/getcwd.c (__getcwd): Do not depend on HAVE_RAW_DECL_GETCWD. * m4/getcwd-path-max.m4 (gl_FUNC_GETCWD_PATH_MAX): Test the getcwd function, not any macro, since getcwd.c wants the function. * m4/getcwd.m4 (gl_FUNC_GETCWD): Don't define HAVE_MINIMALLY_WORKING_GETCWD if the code doesn't compile, as might happen if there's a macro but no function. strtod: support coreutils better * lib/strtod.c (underlying_strtod): Just invoke the underlying strtod. HAVE_RAW_DECL_STRTOD might not be correct in coreutils, which disables the raw decl checks. This assumes there is an underlying strtod, but that's a safe assumption these days. (HAVE_RAW_DECL_STRTOD): Remove; no longer used. mountlist: port to HP NonStop Reported by Joachim Schmitz in . * lib/mountlist.c (hasmntopt) [!HAVE_HASMNTOPT]: New function. (MNT_IGNORE) [MNTOPT_IGNORE]: Use it. 2013-02-18 Paul Eggert extern-inline: avoid compilation error with HP-UX cc Reported by Richard Lloyd in . * m4/extern-inline.m4 (_GL_INLINE, _GL_EXTERN_INLINE): Suppress extern inline with HP-UX cc. This should be safe, though it may hurt performance. Perhaps someone with some HP-UX experience can come up with a higher-performance fix. 2013-02-14 Paul Eggert putenv: fix heap corruption with mixed putenv/_putenv Problem reported by Michael Goffioul in . * lib/putenv.c (putenv) [HAVE__PUTENV]: Rely on _putenv to allocate the new environment. * m4/putenv.m4 (gl_PREREQ_PUTENV): New macro. * modules/putenv (configure.ac): Use it. 2013-02-11 Paul Eggert unsetenv etc.: port to Solaris 11 + GNU Emacs * lib/canonicalize-lgpl.c, lib/getaddrinfo.c, lib/getdelim.c: * lib/glob.c, lib/random_r.c, lib/setenv.c, lib/tsearch.c: * lib/unsetenv.c (_GL_ARG_NONNULL): Define before including . GNU Emacs's includes (which is not a great idea but is too painful to fix right now), and without this gnulib change was defining _GL_ARG_NONNULL incorrectly when compiling unsetenv.c on Solaris 11. Fix the problem for unsetenv.c, and fix other similar occurrences. 2013-02-09 Paul Eggert secure_getenv: fix C++ declaration typo * lib/stdlib.in.h (secure_getenv): Fix typo with return type in _GL_CXXALIAS_SYS macro. Reported by John W. Eaton in . 2013-02-08 Paul Eggert careadlinkat: stop exporting careadlinkatcwd Only Emacs used it directly, and Emacs no longer needs it. * NEWS: Document this simplification. * lib/areadlink.c (careadlinkatcwd): Move here from careadlinkat.c, and make it static. Include , for abort, and unistd.h, for readlink. * lib/careadlinkat.c (careadlinkatcwd): Move to areadlink.c.

(Maintainer): Add self. * modules/careadlinkat (Depends-on): Remove readlink. extensions: port better to HP-UX This is merged from git Autoconf. * m4/extensions.m4 (AC_USE_SYSTEM_EXTENSIONS): On hosts that need _XOPEN_SOURCE, define it when configuring, too, so that it's compatible with the value used when compiling. openpty: fix bug where HAVE_OPENPTY is mistakenly 1 Problem reported by Mats Erik Andersson in . * m4/pty.m4 (gl_FUNC_OPENPTY): Define HAVE_OPENPTY when the openpty function exists, not merely when we intend to replace it. This corrects the 2013-01-31 patch, which mistakenly defined HAVE_OPENPTY even on hosts that lacked it. 2013-02-07 Paul Eggert secure_getenv: fix include typo * lib/secure_getenv.c: Include config.h. Somehow I forgot! secure_getenv: port better to FreeBSD and Solaris * lib/secure_getenv.c [!HAVE___SECURE_GETENV]: Include unistd.h if HAVE_ISSETUGID, otherwise define a dummy issetugid. (secure_getenv) [!HAVE___SECURE_GETENV]: Use getenv if not issetugid. This works better on BSDish platforms. * m4/secure_getenv.m4 (gl_PREREQ_SECURE_GETENV): Test for issetugid if __secure_getenv is missing. 2013-02-06 Paul Eggert extensions: port better to MINIX 3, HP-UX, autoheader 2.62 Some of these changes are merged in from git Autoconf. * m4/extensions.m4 (AC_USE_SYSTEM_EXTENSIONS): When deciding whether to define _XOPEN_SOURCE, inspect the preprocessor macro __hpux instead of the more-heavyweight operation of requiring AC_CANONICAL_HOST. Define _NETBSD_HOST on MINIX, for MINIX 3. Use USE_SYSTEM_EXTENSIONS, not __EXTENSIONS__, as the key for __EXTENSIONS__. unistd: avoid namespace pollution on non-glibc systems * lib/unistd.in.h: #define __need_getopt before including . This avoids namespace pollution on non-glibc systems, by causing gnulib unistd.h to behave more like glibc unistd.h. I also hope that this fixes a bug on FreeBSD, reported by Mats Erik Andersson in . 2013-02-04 Paul Eggert tmpdir: use secure_getenv * lib/tmpdir.c (__secure_getenv) [!LIBC]: Define to secure_getenv, not getenv. * m4/tmpdir.m4 (gt_TMPDIR): Don't check for __secure_getenv, as that's now secure_getenv's job. * modules/tmpdir (Depends-on): Add secure_getenv. tempname: use secure_getenv * lib/tempname.c (__secure_getenv) [!_LIBC]: Define to secure_getenv, not getenv. * modules/tempname (Depends-on): Add secure_getenv. secure_getenv: new module * MODULES.html.sh (Extra functions based on ANSI C 89): Add secure_getenv. * doc/glibc-functions/secure_getenv.texi: New file. * doc/gnulib.texi: Include it. * lib/secure_getenv.c, m4/secure_getenv.m4, modules/secure_getenv: New files. * lib/stdlib.in.h (secure_getenv): New decl. * m4/stdlib_h.m4 (gl_STDLIB_H, gl_STDLIB_H_DEFAULTS): * modules/stdlib (stdlib.h): Add secure_getenv checks. 2013-02-03 Paul Eggert getcwd: break fdopendir + save_cwd recursive loop (Bug#13516) Reported for OS X 10.8.2 by Assaf Gordon in . * lib/getcwd.c (HAVE_OPENAT_SUPPORT): Do not define if !HAVE_OPENAT && !HAVE_FDOPENDIR. * m4/getcwd-abort-bug.m4: Reformat to match test-getcwd.c so that they can be kept in sync more easily. Avoid PATH_MAX test on the Hurd. Sync from test-getcwd.c for errno tests after mkdir or chdir failure. * tests/test-getcwd.c (HAVE_OPENAT_SUPPORT): New macro, from lib/getcwd.c. (test_abort_bug): Do not test for the deep directory bug unless we have openat support. Avoid PATH_MAX test on the Hurd. regex-tests, regex: fix bug: memset undeclared * tests/test-regex.c: Don't include regex.h twice. Include string.h, to declare memset. Christensen's report also mentioned this issue. * m4/regex.m4 (gl_REGEX): Keep test program more in sync with test-regex.c, to avoid future problems like this. Remove AC_INCLUDES_DEFAULT. Include . Don't include twice. regex-tests: fix link errors on older Solaris These need to link with @LIBINTL@ to get libintl_gettext. Problem reported by Tom G. Christensen in . * modules/regex-tests (test_regex_LDADD): New macro. 2013-01-31 Paul Eggert regex-tests: new module * modules/regex-tests, tests/test-regex.c: New files. regex: fix off-by-one error in configure test * m4/regex.m4 (gl_REGEX): Test should return 21, not 20. 2013-01-31 Eric Blake regex: avoid infinite configure test * m4/regex.m4 (gl_REGEX): Add an alarm escape hatch. 2013-01-31 Reuben Thomas openpty: fix bug where HAVE_OPENPTY wasn't defined See the thread starting at: http://lists.gnu.org/r/bug-gnulib/2013-01/msg00185.html * m4/pty.m4 (gl_FUNC_OPENPTY): Define HAVE_OPENPTY when the openpty function exists, not merely when we intend to replace it. 2013-01-30 Paul Eggert sys_time: port to Solaris 2.6 There is a circularity problem on Solaris 2.6, where includes for struct timespec. The include nesting is gnulib , system , gnulib , system , gnulib , system , gnulib , gnulib , system , system ; the last, innermost file needs struct timestruc_t, which is defined in , which has not been fully parsed. Problem reported by Tom G. Christensen in . * lib/sys_select.in.h: Treat Solaris 2.6's problem with and like OSF/1's similar problem. * lib/sys_time.in.h: Redo to resemble sys_select.in.h, which uses split double-inclusion guards. 2013-01-29 Paul Eggert regex: test for buffer overrun * m4/regex.m4 (gl_REGEX): Add test case, by Andreas Schwab, for the just-fixed regex bug. 2013-01-29 Andreas Schwab regex: fix buffer overrun in regexp matcher [BZ #15078] * lib/regexec.c (extend_buffers): Add parameter min_len. (check_matching): Pass minimum needed length. (clean_state_log_if_needed): Likewise. (get_subexp): Likewise. 2013-01-28 Pádraig Brady mountlist: don't consider "devtmpfs" as dummy * lib/mountlist.c (ME_DUMMY_0): Remove "devtmpfs" as there is storage associcated with it. 2013-01-27 Paul Eggert futimens-tests, utimens-tests: Depend on gettext. This works around a problem introduced in my 2013-01-12 patch, which added @LIBINTL@ to these modules. * modules/futimens-tests (Depends-on): * modules/utimens-tests (Depends-on): Add gettext. 2013-01-26 Eric Blake test-getpeername: fix typo * tests/test-getpeername.c: Fix typo introduced in fd cleanup. 2013-01-20 Bernhard Voelker bootstrap: remove the need for a sorted .gitignore file * build-aux/bootstrap (insert_sorted_if_absent): Adjust and rename to insert_if_absent(), so that we don't need or generate a sorted .gitignore file. We do require a .gitignore with no existing duplicate entries and enforce that. (sort_patterns): Remove this function as we now use the simpler technigue of inserting blacklist entries at the top of the file, assuming gnulib won't be inserting !whitelist entries. 2013-01-23 Paul Eggert readlinkat: don't depend on gl_FUNC_OPENAT * m4/readlinkat.m4 (gl_FUNC_READLINKAT): Don't require gl_FUNC_OPENAT. Perhaps a similar change needs to be made for linkat.m4, mkfifoat.m4, renameat.m4, symlinkat.m4; but one thing at a time. statat: new module, split out from fstatat GNU Emacs needs the POSIX-specified fstatat, but not the gnulib-specified statat and lstat. Split the latter two into a new module 'statat'. * lib/openat.h: Depend on GNULIB_STATAT, not GNULIB_FSTATAT. * lib/openat.h, lib/statat.c (STATAT_INLINE): Rename from FSTATAT_INLINE.

Problem reported by Assaf Gordon in . 2013-01-16 Paul Eggert unistd: port to recent mingw * lib/unistd.in.h: Remove special invocation convention for mingw, which breaks for the latest mingw version. See John W. Eaton in . largefile: port better to Mac OS X 10.5 This patch is backported from Autoconf git. * m4/largefile.m4 (AC_SYS_LARGEFILE): Use AC_DEFINE, not AH_VERBATIM, to define _DARWIN_USE_64_BIT_INODE, to avoid problems with ino_t size being different for configuration time versus build/run time. Problem reported by PHO in . 2013-01-15 Paul Eggert doc: clarify -Werror * doc/warnings.texi (warnings): -Werror is not always a bad idea; clarify that it's intended for developers, not for ordinary builds, and mention --enable-gcc-warnings as one possible use. 2013-01-15 Andoni Morales Alastruey (tiny change) stdint: fix build with Android's Bionic fox x86 * lib/stdint.in.h: fix check to test if included-fixed/sys/types.h was already included as _SSIZE_T_DEFINED_ might also be defined in include/machine/_types.h, which is included by stdio.h 2013-01-13 Paul Eggert net_if-tests: port to Solaris 7 + GCC 3.4.6 Problem reported by Tom G.

Christensen in . 2013-01-04 Paul Eggert fprintftime: bring back and reword fwrite comment * lib/strftime.c (cpy) [FPRINTFTIME]: Re-add reworded comment. stdio: remove now-unnecessary stdio.c Since stdio.in.h no longer uses inline functions, we no longer need to compile the extern versions. * lib/stdio.c: Remove. * modules/stdio (Files): Remove lib/stdio.c. (lib_SOURCES): Remove. unicodeio: depend on stdio, not ignore-value * lib/unicodeio.c: Do not include ignore-value.h. (fwrite_success_callback): Use plain fwrite, not ignore_value + fwrite. * modules/unicodeio (Depends-on): Depend on stdio, not ignore-value. fprintftime: depend on stdio, not ignore-value * lib/strftime.c [FPRINTFTIME]: Do not include ignore-value.h. (cpy) [FPRINTFTIME]: Use plain fwrite, not ignore_value of fwrite, since the stdio module arranges to silence that warning now. * modules/fprintftime (Depends-on): Depend on stdio, not ignore-value. 2012-10-04 Simon Josefsson stdint-tests: Fix expanded-before-required-warning. * modules/stdint-tests (Depends-on): Use AC_REQUIRE. 2013-01-03 Paul Eggert fwrite: silence __wur only for older glibc versions * lib/stdio.in.h (fwrite): Limit workaround to glibc 2.4 through 2.15. This will help us remove this workaround some time in the far future. 2013-01-03 Eric Blake fwrite: silence __wur without using inline * lib/stdio.in.h (fwrite): Limit warn_unused_result workaround to just gcc, and in a way that avoids inline issues. * modules/stdio (Depends-on): Drop extern-inline. 2013-01-03 Jim Meyering update-copyright: avoid copyright notice date corruption Given a sequence of copyright year numbers in which the final one was a two-digit number that happened to be a substring of a preceding four-digit year number, we would mistakenly update the substring (from two- to four-digit) rather than the two-digit number at the end, which, combined with the addition of the current 4-digit year number would yield two 5-digit year numbers, e.g., here, it would convert the first "99" to "1999, 2013" rather than the final one: 1991, 99 11999, 20131, 1999 * build-aux/update-copyright: Tighten a regexp. * tests/test-update-copyright.sh: Add a test case to trigger the bug. Reported by Joseph Myers in http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/32281 2013-01-01 Paul Eggert regex: omit needless signed-pointer casts * lib/regcomp.c (build_charclass, build_charclass_op): Use char *, not unsigned char *, for class name and extra. The char values are always nonnegative so there's no need to insist on unsigned char * here, and using char * removes the need for casts. Reported by Aharon Robbins in . regex: support Gawk, which never uses alloca * lib/regex_internal.h [!_LIBC && !HAVE_ALLOCA]: Do not include in this case. Gawk doesn't supply a substitute alloca.h and doesn't need one. regex: port __libc_lock_define usage to C89 * lib/regex_internal.h (__libc_lock_define) [!_LIBC]: Remove. (struct re_dfa_t): Use #ifdef instead. '__libc_lock_define (, lock)' does not conform to C89, as it has an empty macro argument. Reported by Aharon Robbins in . 2013-01-01 Eric Blake maint: update all copyright year number ranges Run "make update-copyright". version-etc: bump copyright year reported in --version * lib/version-etc.c (COPYRIGHT_YEAR): Update to 2013. 2012-12-31 Eric Blake sigprocmask-tests: skip test if pid is unexpectedly large * tests/test-sigprocmask.c (main): Add range check. git-version-gen: avoid test -z portability glitch * build-aux/git-version-gen: Prefer portable test spelling, since git-version-gen is run on more than just developer machines. 2012-12-31 Peter Rosin (tiny change) git-version-gen: add --fallback option to use if git is not present * build-aux/git-version-gen: Add support for the new option --fallback, which comes into play when there is no $tarball_version_file and git is not working. (scriptversion): Update. maint.mk: handle missing git with more grace * top/maint.mk (no-submodule-changes, public-submodule-commit): Quietly proceed if git is not present. 2012-12-31 Eric Blake dup2: work around cygwin bug * m4/dup2.m4 (gl_FUNC_DUP2): Flush out cygwin core dump. * lib/dup2.c (rpl_dup2): Work around it. * doc/posix-functions/dup2.texi (dup2): Document it. 2012-12-30 Paul Eggert regex: remove unnecessary dependency on localcharset.h * lib/regex_internal.h [!_LIBC]: Don't include localcharset.h; hasn't been needed for years. * modules/regex (Depends-on): Remove localcharset. regex: revert single-byte change * lib/regexec.c (check_node_accept_bytes): Revert previous change to this function. This was alredy fixed in a different way, at bdb56bacd57070eced9998569ffe3f3c37ef5964 in the glibc git; see and . regex: simplify based on Gawk version * lib/regex_internal.c (re_dfa_add_node): Simplify. Reported by Aharon Robbins in . 2012-12-29 Paul Eggert regex: check that pattern char is single-byte Reported by Aharon Robbins in . * lib/regexec.c (check_node_accept_bytes): Return 0 if the pattern string has a multibyte character here. regex: implement rational ranges Reported by Aharon Robbins in . * lib/regcomp.c (build_range_exp) [!_LIBC]: * lib/regexec.c (check_node_accept_bytes) [!_LIBC]: Implement rational ranges. regex: avoid redefining __wctype Reported by Aharon Robbins in . * lib/regex_internal.h (__wctype, __iswctype) [!_LIBC]: #undef before defining. regex: port to hosts where malloc (0) == NULL Reported by Aharon Robbins in . * lib/regex_internal.c (re_node_set_alloc): Don't assume that malloc (0) yields nonnull. * lib/regex_internal.h (MALLOC_0_IS_NONNULL): New macro. * m4/regex.m4 (gl_PREREQ_REGEX): Require gl_EEMALLOC. * modules/regex (Files): Add m4/eealloc.m4. regex: port to C89 Reported by Aharon Robbins in . * lib/regcomp.c (init_word_char): Declaration before statement. regex: merge glibc changes Also, copy the license wording from glibc. This simplifies merging changes. gnulib-tool will change the wording to GPL as appropriate, when importing it to other packages. The only glibc change made since the last merge, which needs merging, is: 2012-05-24 Andreas Schwab * lib/regex_internal.h (gettext): Remove use of INTUSE. * users.txt: Add Emacs. doc: omit mention of version when not needed * doc/gnulib-intro.texi (Portability and Application Code): * doc/gnulib.texi (Brief Overview, Legacy Function Substitutes): Don't mention particular dates or versions when not necessary, so that the documentation won't go out of date so quickly. * doc/intprops.texi (Integer Properties): Fix Texinfo typo. 2012-12-28 Akim Demaille bootstrap: pass --force to autoreconf. * build-aux/bootstrap (AUTORECONFFLAGS): New. Add "--force" so that Automake's ylwrap and other such tools be updated at each bootstrap invocation. Use it. 2012-12-27 Paul Eggert argp: fix port of port new 'inline' approach to Sun C 5.12 + Solaris 10 The earlier patch forgot to update one of the #if conditions, causing a problem on Debian testing i386 reported by Mats Erik Andersson . * lib/argp-fmtstream.h (__argp_fmtstream_putc, argp_fmtstream_putc) (__argp_fmtstream_puts, argp_fmtstream_puts) (__argp_fmtstream_write, argp_fmtstream_write) [!_LIBC && !__OPTIMIZE__]: Declare as ARGP_FS_EI, not as extern. * doc/gnulib-readme.texi: Minor fixups. (Portability guidelines): Modernize URLs. Remove some repetition. (Indent with spaces not TABs): Reword to avoid too-long lines. Remove some '@ifset standalone' stuff that isn't used. * doc/gnulib-readme.texi (Portability guidelines): ctype.h, not ctime.h. Correct name of POSIX.1-2001. * doc/posix-functions/fgetc.texi (fgetc): * doc/posix-functions/fgets.texi (fgets): * doc/posix-functions/fread.texi (fread): * doc/posix-functions/fscanf.texi (fscanf): * doc/posix-functions/getc.texi (getc): * doc/posix-functions/getchar.texi (getchar): * doc/posix-functions/scanf.texi (scanf): POSIX.1-2001, not POSIX-2001. doc: move README into manual * README: Move contents to new file doc/gnulib-readme.texi. Replace with a one-line summary. * doc/gnulib.texi (Brief Overview): New section, with old intro preface. Include gnulib-readme.texi for contents. (Philosophy): Rename from "Introduction", since this section no longer introduces the rest. Write a new preface. * doc/gnulib-readme.texi: New file, with the old contents of README texinfo-ized. This way, the README info appears in the online and printed manual. 2012-12-25 Ben Pfaff c-xvasprintf: Fix "implicit declaration of function" GCC warning. * lib/c-xvasprintf.c: Add missing #include "c-vasprintf.h", for c_vasprintf() prototype. 2012-12-24 Ben Pfaff c-vasprintf: Fix "empty declaration" warning reported by GCC. * lib/c-vasprintf.h: Remove stray semicolon. 2012-12-23 Paul Eggert gettext: avoid obsolete macro AM_PROG_MKDIR_P It is obsolete and is planned to be removed from Automake 1.14; see . * build-aux/po/Makefile.in.in (install-data, install-data-yes) (installdirs-data, installdirs-data-yes): Use $(MKDIR_P), not $(mkdir_p). * m4/intl.m4 (AM_INTL_SUBDIR): * m4/po.m4 (AM_PO_SUBDIRS): Require AC_PROG_MKDIR_P, not AM_PROG_MKDIR_P. 2012-12-22 Paul Eggert argp: port new 'inline' approach to Sun C 5.12 + Solaris 10 On this platform, we are not optimizing but we are using the substitute for extern inlines, so compile as if C99-style extern inline, or a substitute, is available. * lib/argp-fmtstream.h (argp_fmtstream_set_lmargin) (__argp_fmtstream_set_lmargin, argp_fmtstream_set_rmargin) (__argp_fmtstream_set_rmargin, argp_fmtstream_set_wmargin) (__argp_fmtstream_set_wmargin, argp_fmtstream_point) (__argp_fmtstream_point) [!_LIBC && !__OPTIMIZE__]: Declare as ARGP_FS_EI, not as extern. * lib/argp.h (argp_usage, __argp_usage, _option_is_short) (__option_is_short, _option_is_end, __option_is_end) [!_LIBC && __USE_EXTERN_INLINES]: Declare as ARGP_EI, not as extern. 2012-12-21 Paul Eggert AC_PROG_MKDIR_P: port workaround to pre-2.62 Autoconf * m4/gnulib-common.m4 (AC_PROG_MKDIR_P, AC_C_RESTRICT): Use m4_ifndef([AC_AUTOCONF_VERSION], ...), not m4_if(m4_version_compare(m4_defn([AC_AUTOCONF_VERSION]),[2.62]),[-1], ...), as the latter is fatal with older Autoconfs. Problem reported and fix suggested by Eric Blake in thread starting at . 2012-12-20 Paul Eggert AC_PROG_MKDIR_P: don't workaround if not buggy * m4/gnulib-common.m4 (AC_PROG_MKDIR_P): Define only for Autoconf versions before 2.62. (AC_C_RESTRICT): Use documented AC_AUTOCONF_VERSION, not undocumented m4_PACKAGE_VERSION, for consistency with the abovementioned change to AC_PROG_MKDIR_P. This should suffice since we're checking for 2.62 or later, and AC_AUTOCONF_VERSION was introduced in 2.62. 2012-12-15 Ben Pfaff New 'c-*printf' modules for formatted output in C locale.

Use _GL_UNUSED in the non-inline branch. Problem reported by Akim Demaille in . 2012-12-11 Simon Josefsson gnupload: Work with GnuPG using gpg-agent (for smartcards). * build-aux/gnupload: If GnuPG is configured to use gpg-agent, let it handle password prompting. 2012-12-10 Eli Zaretskii canonicalize, canonicalize-lgpl: Microsoft Windows prefix fixes * lib/canonicalize.c (canonicalize_filename_mode): * lib/canonicalize-lgpl.c (__realpath): Recompute prefix_len after fetching the current directory. Don't overrun the beginning of rpath if there's no slashes after the MS-Windows drive letter. 2012-12-08 Stefano Lattarini maint.mk: avoid extra forks * top/maint.mk (_cfg_mk): The GNU make manual documents that "$(wildcard FILE)" expands to empty if FILE doesn't exist. So use that instead of "$(shell test -f FILE && echo FILE)". 2012-12-07 Paul Eggert vasnprintf: fix ASCII_ONLY typo * lib/unistdio/u8-vasnprintf.c (FCHAR_T_ONLY_ASCII): * lib/unistdio/u16-vasnprintf.c (FCHAR_T_ONLY_ASCII): * lib/unistdio/u32-vasnprintf.c (FCHAR_T_ONLY_ASCII): New macro, replacing ASCII_ONLY.

Also allow errno == ENOENT * tests/test-getlogin_r.c (main): Skip tests if getlogin_r fails with errno == ENOENT. This was reported to happen in various situations on GNU/Linux. 2012-11-09 Paul Eggert getlogin-tests: allow errno == ENOENT * tests/test-getlogin.c (main): Skip tests if getlogin fails with errno == ENOENT.

Reported by Matias A. fonzo in http://bugs.gnu.org/12830. 2012-11-08 Paul Eggert fcntl-h: default O_SEARCH, O_EXEC back to O_RDONLY O_PATH doesn't work with Linux kernel 3.6.5, as fchmod (fd, ...) fails with errno == EBADF when fd is opened with O_PATH. Reported by Jim Meyering in . * doc/posix-headers/fcntl.texi (fcntl.h): Document this. * lib/fcntl.in.h (O_EXEC, O_SEARCH) [O_PATH]: Default back to O_RDONLY. 2012-11-07 Paul Eggert test-utimens: speed up by taking shorter naps * tests/nap.h (lt_mtime, get_mtime, nap_works, guess_delay): New functions. (nap): Use them, to do a better job of guessing the delay. On Fedora 17 with ext4 atop md atop hard disks, this made test-utimens run 10x faster, because the test napped for 1 ms at a time rather than 20 ms. Reported by Stefano Lattarini in . 2012-11-07 Jim Meyering mountlist.c: fix a compilation failure * lib/mountlist.c (read_file_system_list): Fix a compilation failure I introduced while transforming commit v0.0-7683-g613bcb6 2012-11-05 Paul Eggert errno: port to LynxOS 178 2.2.2 Problem reported by Joel Brobecker in . * doc/posix-headers/errno.texi (errno.h): Document this. * lib/errno.in.h (EILSEQ, GNULIB_defined_EILSEQ) [!EILSEQ]: New macros. * lib/strerror-override.c, lib/strerror-override.h (strerror_override): Supply a string for EILSEQ. * m4/errno_h.m4 (gl_HEADER_ERRNO_H): Check for EILSEQ. 2012-11-05 Paul Eggert fcntl-h: default O_SEARCH, O_EXEC to O_PATH if available Linux kernel 2.6.39 introduced O_PATH (see ) and this is a better fallback for O_SEARCH and O_EXEC than O_RDONLY, if O_PATH is available. * doc/posix-headers/fcntl.texi (fcntl.h): Document this. * lib/fcntl.in.h (O_EXEC, O_SEARCH) [O_PATH]: Default to O_PATH. * lib/fcntl.in.h (O_ACCMODE): * tests/test-fcntl-h.c (main): Do not reject O_ACCMODE merely because it has more than the minimal number of bits, as POSIX allows extensions here. 2012-11-04 Andrew Warshall (tiny change) mountlist: do not classify a bind-mounted dir entry as "dummy" * lib/mountlist.c (ME_DUMMY_0): Rename from ME_DUMMY, but omit the "none"-testing clause. (ME_DUMMY) [MOUNTED_GETMNTENT1]: New macro to encapsulate the exception for bind-mounted directories. 2012-11-01 Akim Demaille quote: provide a means to escape strings with nul characters * lib/quote.h, lib/quotearg.c (quote_mem, quote_n_mem): New functions. (quote, quote_n): Rename formal arguments for consistency with quotearg. 2012-10-30 Paul Eggert test-raise: don't assume 199 is an invalid signal * tests/test-raise.c (main): Don't assume 199 is not a signal number. sh-quote-tests: port to Solaris 9 * modules/sh-quote-tests (test_sh_quote_LDADD): Add @LIBINTL@. Problem reported by Dagobert Michelsen in . 2012-10-28 Jim Meyering maint.mk: rename a new configurable variable * top/maint.mk (_gl_translatable_string_re): Rename from translation-markers: _gl_ prefix to insulate from user Makefile code, and the _re suffix to inform that it's a regular expression. 2012-10-26 Eric Blake maint.mk: let packages tweak sc_po_check pattern * top/maint.mk (sc_po_check): Add translation-markers, to allow finding files with other translation markers. 2012-10-16 Paul Eggert euidaccess: speed up 'configure' on GNU hosts * m4/euidaccess.m4 (gl_FUNC_NONREENTRANT_EUIDACCESS): Check for setregid here, not in gl_PREREQ_EUIDACCESS, since it's needed only in this case. Use AC_CHECK_DECLS, not AC_CHECK_DECLS_ONCE. (gl_PREREQ_EUIDACCESS): Do not use AC_CHECK_HEADERS_ONCE libgen.h or AC_REQUIRE for AC_FUNC_GETGROUPS. * lib/regexec.c (re_search_internal): Fix grammar in comment. 2012-10-15 Paul Eggert fchmodat, fchownat, fstatat: port to non-inlining compilers Problem reported for FreeBSD 9 by Jim Meyering in . * lib/chmodat.c, lib/chownat.c, lib/statat.c: New files, which define FCHMODAT_INLINE etc. * lib/fchmodat.c (FCHMODAT_INLINE): * lib/fchownat.c (FCHOWNAT_INLINE): * lib/fstatat.c (FSTATAT_INLINE): Remove, as chmodat.c etc. now do this. * modules/fchmodat (Files): Add lib/chmodat.c. * modules/fchownat (Files): Add lib/chownat.c. * modules/fstatat (Files): Add lib/statat.c. 2012-10-15 Jim Meyering fchmodat.c, fchownat.c: compile-impeding typos * lib/fchmodat.c (FCHMODAT_INLINE): Fix typo: s/#include/#define/ * lib/fchownat.c (FCHOWNAT_INLINE): Likewise. Introduced in commit v0.0-7636-gd202279. 2012-10-15 Paul Eggert fcntl-h: support GNU flags like O_IGNORE_CTTY * doc/posix-headers/fcntl.texi (fcntl.h): Support O_IGNORE_CTTY, O_NOLINK, and O_NOTRANS. These flags are nonzero on GNU/Hurd systems. Discovered when using fcntl-h with GNU Emacs, which uses O_IGNORE_CTTY. Fix misspelling of F_SETLKW. * lib/fcntl.in.h (O_IGNORE_CTTY, O_NOLINK, O_NOTRANS): Define to 0 if not already defined. * tests/test-fcntl-h.c: Test these new flags. 2012-10-14 Paul Eggert faccessat, etc.: support AT_FDCWD-only use * lib/at-func.c: If GNULIB_SUPPORT_ONLY_AT_FDCWD, then support this function only if its first argument is AT_FDCWD. Emacs wants faccessat for AT_EACCESS but not for any first-arg values other than AT_FDCWD, so it doesn't want all the openat machinery with fchdir etc. * modules/faccessat, modules/fchmodat, modules/fchownat (Files): * modules/fstatat, modules/mkdirat, modules/openat (Files): * modules/unlinkat (Files): Remove lib/openat-priv.h, as at-internal supplies this file. Removing this file here allows us to support programs like Emacs that avoid at-internal. faccessat: speed up 'configure' on mainstream hosts * m4/faccessat.m4 (gl_PREREQ_FACCESSAT): Use AT_CHECK_FUNCS for 'access', not AC_CHECK_FUNCS_ONCE, since it's only on unusual platforms that we need to check for 'access', and it's better not to slow 'configure' down on all platforms. faccessat: port to Solaris 10 * lib/faccessat.c: Include , for AT_EACCESS. Needed on Solaris 10, which doesn't have AT_EACCESS, so we need the Gnulib fcntl.h, which defines it. 2012-10-14 Pádraig Brady canonicalize: fix C89 compilation * lib/canonicalize.c (canonicalize_filename_mode): Swap order of declarations so C89 is supported. Also remove the comment referencing memorty allocation as the suggested feature could not be implemented as suggested. Reported by Michael Goffioul. 2012-10-12 Paul Eggert group-member: omit unnecessary dependencies This is for Emacs, which has its own allocator and where we don't want to use xalloc. * lib/group-member.c: Include xalloc-oversized.h, not xalloc.h, since we no longer use xmalloc. Do not include stdbool.h, since the changes below happen to remove the only use of bool. (GROUPBUF_SIZE): New constant. (struct group_info): Remove n_groups member. Add groupbuf member. This lets us get the groups without using malloc, usually. (free_group_info, get_group_info): Adjust to this. (get_group_info): Return the number of groups found, or -1 on error. Use plain malloc not xmalloc, and treat its failure as if there are no groups, as the user already loses in case of error. (group_member): Simplify, based on changes to get_group_info. * modules/group-member (Depends-on): Remove dependencies on xalloc and stdbool. Add dependency on xalloc-oversized. 2012-10-08 Alexandre Duret-Lutz (tiny change) gethrxtime: port to C++ * lib/gethrxtime.h, lib/xtime.h [__cplusplus]: Add extern "C". 2012-10-04 Paul Eggert ptsname: fix macro-name typo * lib/stdlib.in.h (ptsname): Fix misspelling of GNULIB_NAMESPACE. 2012-10-03 Simon Josefsson inttostr: Relax license. * modules/inttostr (License): Change from LGPL to LGPLv2+. 2012-10-03 Eric Blake ptsname_r: support ptys returned by FreeBSD posix_openpt * lib/ptsname_r.c (__ptsname_r): Don't munge name if it already lives in /dev/pts/. 2012-10-02 Eric Blake pselect: reject invalid file descriptors * m4/pselect.m4 (gl_FUNC_PSELECT): Probe for FreeBSD bug. * lib/pselect.c (rpl_pselect) [!win32]: Work around it. * modules/pselect (Depends-on): Add dup2. * doc/posix-functions/pselect.texi (pselect): Document this. select: reject invalid file descriptors * m4/select.m4 (gl_FUNC_SELECT): Probe for FreeBSD bug. * lib/select.c (rpl_select) [!win32]: Work around it. * modules/select (Depends-on): Add dup2. * doc/posix-functions/select.texi (select): Document this. select: enhance test * tests/test-select.h (do_select_bad_nfd_nowait, test_bad_nfd): New functions.

Reported by Bruno Haible in . 2012-09-30 Bruno Haible localeconv tests: Avoid test failure on OpenIndiana. * tests/test-localeconv.c (main): On OpenIndiana (a Solaris 11 variant) skip the 'grouping' and 'mon_grouping' tests. Reported by Jim Meyering. 2012-09-30 Bruno Haible havelib: Follow libtool developments. * m4/lib-ld.m4: Rebase on libtool.m4 from libtool-2.4.

Mats Erik Andersson reported the resulting OpenBSD compilation failure. 2012-09-28 Akim Demaille extern-inline: provide a -Wundef safe config.h * m4/extern-inline.m4 (gl_EXTERN_INLINE): Protect "#if __GNUC_STDC_INLINE__" with "defined __GNUC_STDC_INLINE__" to produce a -Wundef warning free config.h. 2012-09-26 Paul Eggert hash-pjw: relax license to LGPLv2+ * modules/hash-pjw (License): Relax, with consent of author. 2012-09-25 Akim Demaille maint.mk: fix strict vs. lazy variable issues with RELEASE * top/maint.mk (_equal): New function. (member_check): Strip the result to avoid spurious spaces. (url_dir_list): Do not use ifeq, which is strict, as it will require RELEASE_TYPE to be defined. (announcement_Cc_, announcement_mail_headers_): Likewise: instead of relying on ifeq, use $(release_type) to dispatch (lazily) onto... (announcement_Cc_alpha,announcement_mail_headers_alpha) (announcement_Cc_beta,announcement_mail_headers_beta) (announcement_Cc_stable,announcement_mail_headers_stable): these. (release): Do not depend on $(release-type), as it forces its evaluation.

(member-check, release-type): New. Use the latter instead of $(RELEASE_TYPE). Remove now useless local checks. 2012-09-20 Akim Demaille maint.mk: provide "make upload" to ease uploading See . Do not depend simply on the current $(VERSION), as there may have been new commits since the tarball generation. Rather, rely on $(RELEASE), as "make release-commit" already does. For consistency, add "make release RELEASE='X.Y TYPE'" as an alias for "make TYPE". * top/maint.mk (upload_command, upload, release): New. (RELEASE_TYPE): If undefined, default to the second word of $(RELEASE). (VERSION): first word of $(RELEASE) is always right.

Original idea suggested by Ed Maste in . 2012-09-22 Paul Eggert binary-io, eealloc, mbfile, mbiter, mbutil, xsize: better 'inline' * lib/binary-io.c, lib/eealloc.c, lib/mbfile.c, lib/mbiter.c: * lib/mbuiter.c, lib/xsize.c: New files. * lib/binary-io.h (BINARY_IO_INLINE): * lib/eealloc.h (EEALLOC_INLINE): * lib/mbfile.h (MBFILE_INLINE): * lib/mbiter.h (MBITER_INLINE): * lib/mbuiter.h (MBUITER_INLINE): * lib/xsize.h (XSIZE_INLINE): New macros. Replace all uses of 'static inline' with them. Use _GL_INLINE_HEADER_BEGIN, _GL_INLINE_HEADER_END. * m4/eealloc.m4 (gl_EEALLOC): * m4/mbfile.m4 (gl_MBFILE): * m4/mbiter.m4 (gl_MBITER): * m4/xsize.m4 (gl_XSIZE): Do not require AC_C_INLINE. * modules/binary-io (Files, lib_SOURCES): Add lib/binary-io.c * modules/eealloc (Files, lib_SOURCES): Add lib/eealloc.c. * modules/mbfile (Files, lib_SOURCES): Add lib/mbfile.c. * modules/mbiter (Files, lib_SOURCES): Add lib/mbiter.c. * modules/mbuiter (Files, lib_SOURCES): Add lib/mbuiter.c. * modules/xsize (Files, lib_SOURCES): Add lib/xsize.c. * modules/binary-io, modules/eealloc, modules/mbfile: * modules/mbiter, modules/mbuiter: (Depends-on): Add extern-inline. pipe-filter-gi, pipe-filter-ii: better use of 'inline' * lib/pipe-filter-aux.c: New file. * lib/pipe-filter-aux.h (PIPE_FILTER_AUX_INLINE): New macro. Replace all uses of 'static inline' with it. Use _GL_INLINE_HEADER_BEGIN, _GL_INLINE_HEADER_END. * lib/pipe-filter-gi.c (filter_init, filter_cleanup) (filter_retcode): No real need for inline here. * modules/pipe-filter-gi, modules/pipe-filter-ii: (Files): Add lib/pipe-filter-aux.c. (Depends-on): Add extern-inline. (configure.ac): Do not require AC_C_INLINE. (lib_SOURCES): Add pipe-filter-aux.c. fdutimensat: omit unnecessary AC_C_INLINE * modules/fdutimensat (configure.ac): Remove AC_C_INLINE. fchmodat, fchownat, fstatat: use extern-inline * lib/fchmodat.c, lib/openat.h (FCHMODAT_INLINE): * lib/fchownat.c, lib/openat.h (FCHOWNAT_INLINE): * lib/fstatat.c, lib/openat.h (FSTATAT_INLINE): New macros. * lib/openat.h: Replace all uses of 'static inline' with them. Use _GL_INLINE_HEADER_BEGIN, _GL_INLINE_HEADER_END. * modules/fchmodat, modules/fchownat, modules/fstatat: * modules/openat-h: (Depends-on): Add extern-inline. (configure.ac): Remove AC_C_INLINE. acl, mbchar, priv-set: use extern-inline * lib/set-mode-acl.c, lib/acl-internal.h (ACL_INTERNAL_INLINE): * lib/mbchar.c, lib/mbchar.h (MBCHAR_INLINE): * lib/priv-set.c, lib/priv-set.h (PRIV_SET_INLINE): New macros. * lib/acl-internal.h, lib/mbchar.h, lib/priv-set.h: Replace all uses of 'static inline' with it. Use _GL_INLINE_HEADER_BEGIN, _GL_INLINE_HEADER_END. * m4/acl.m4 (gl_FUNC_ACL): * m4/mbchar.m4 (gl_MBCHAR): * m4/priv-set.m4 (gl_PRIV_SET): Remove AC_C_INLINE, since 'inline' is no longer used directly. * modules/acl, modules/mbchar, modules/priv-set (Depends-on): Add extern-inline. sockets, sys_stat: remove AC_C_INLINE in MSVC-only cases * m4/sockets.m4 (gl_SOCKETS): * m4/sys_stat_h.m4 (gl_HEADER_SYS_STAT_H): Remove AC_C_INLINE. Here, 'inline' is used only in MSVC environments where it's already guaranteed to work, so we needn't check for it at 'configure'-time. tls-tests: omit unnecessary 'inline' * tests/test-tls.c (perhaps_yield): No longer inline. Simplicity and portability trump efficiency in test cases. utimens-tests: avoid unnecessary 'inline' * modules/fdutimensat-tests (configure.ac): * modules/futimens-tests (configure.ac): * modules/utimens-tests (configure.ac): * modules/utimensat-tests (configure.ac): Remove AC_C_INLINE. * tests/test-utimens-common.h (ctime_compare): No longer inline. Simplicity and portability trump efficiency here. misc: don't limit commentary to inline functions * lib/binary-io.h, lib/malloca.h, lib/safe-alloc.c: * lib/xalloc-oversized.h, lib/xsize.h: Contrast macros to functions in general, not just to inline functions, when the commentary does not apply only to inline functions. 2012-09-20 Jim Meyering non-recursive-gnulib-prefix-hack: new module * build-aux/prefix-gnulib-mk: Copied from coreutils, derived from the file that originated in Bison. * m4/non-recursive-gnulib-prefix-hack.m4: Likewise, this code is largely copied from a snippet that resided in bison's configure.ac. * modules/non-recursive-gnulib-prefix-hack: New file. * MODULES.html.sh (Support for maintaining and releasing projects): Add it. 2012-09-18 Jim Meyering maint.mk: generalize _gl_tight_scope for non-recursive make * top/maint.mk (_gl_tight_scope): Remove a hard-coded assumption that *.h would describe additional .h files in the directory specified by $(_gl_TS_dir). I.e., add this... (_gl_TS_other_headers): New variable. maint.mk: exempt trailing blanks found in "binary" files * top/maint.mk (sc_trailing_blank): Filter out any matches found in "binary" files, as reported by grep. Suggested by Richard W.M. Jones in http://thread.gmane.org/gmane.comp.emulators.guestfs/1902 2012-09-17 Jim Meyering maint.mk: sc_prohibit_path_max_allocation: don't FP for UNIX_PATH_MAX * top/maint.mk (sc_prohibit_path_max_allocation): Avoid false-positive match for symbols like UNIX_PATH_MAX. Reported by Richard W.M. Jones in http://thread.gmane.org/gmane.comp.emulators.guestfs/1902 2012-09-17 Jim Meyering maint.mk: teach sc_prohibit_magic_number_exit to accept 77 * top/maint.mk (sc_prohibit_magic_number_exit): Do not complain about uses like "exit (77)". "77" is automake's "skip this test" exit code. It is not in the same category as "exit (0)" or "exit (1)", and besides, I know of no symbolic name for that 77. Reported by Richard W.M. Jones in http://thread.gmane.org/gmane.comp.emulators.guestfs/1902 2012-09-17 Jim Meyering maint.mk: relax sc_prohibit_strcmp, to avoid a false positive * top/maint.mk (sc_prohibit_strcmp): Relax regexp, so as to match all uses of #define, not just those that start in column 1. Richard W.M. Jones reported a false positive in http://thread.gmane.org/gmane.comp.emulators.guestfs/1902 2012-09-16 Paul Eggert localcharset: work around Mac OS X bug with UTF-8 and MB_CUR_MAX * lib/localcharset.c (locale_charset) [DARWIN7]: Return "ASCII" if the system reports "UTF-8" and MB_CUR_MAX <= 1, as these two values are incompatible. Problem reported by Max Horn. For more discussion, please see . doc: document sticky-EOF issue * doc/posix-functions/fgetc.texi (fgetc): * doc/posix-functions/fgets.texi (fgets): * doc/posix-functions/fread.texi (fread): * doc/posix-functions/fscanf.texi (fscanf): * doc/posix-functions/getc.texi (getc): * doc/posix-functions/getchar.texi (getchar): * doc/posix-functions/scanf.texi (scanf): Mention that glibc and default Solaris do not conform to C99 and POSIX-2001 or later, with respect to how getchar etc. behave when feof reports nonzero. 2012-09-13 Joachim Schmitz (tiny change) poll: fix poll(0, NULL, msec) * lib/poll.c: don't exit early if NULL is the 1st arg to poll(), but nfd is 0. In that case poll should behave like select. 2012-09-13 Joachim Schmitz (tiny change) Paolo Bonzini poll: fix for systems that can't recv() on a non-socket * lib/poll.c: if recv returns ENOTSOCK, assume the descriptor is readable. In this case POLLHUP will not be supported. * doc/posix-functions/poll.texi: Document this. 2012-09-13 Paolo Bonzini poll/select: document portability problems not fixed by Gnulib. * doc/posix-functions/poll.texi: poll does not work well on pipes under Windows. It has the same limitations as select on BeOS. * doc/posix-functions/select.texi: select does not work well on pipes under Windows. 2012-09-10 Paul Eggert fcntl-h: check for AIX 7.1 bug with O_NOFOLLOW and O_CREAT * m4/fcntl-o.m4 (gl_FCNTL_O_FLAGS): Check for AIX 7.1 bug that caused a GNU tar test failure. Problem reported by Jez Wain; see . 2012-09-06 Eric Blake net_if: give more details about the bug being fixed * doc/posix-headers/net_if.texi: Add clarification. 2012-09-05 Eric Blake net_if: new module * modules/net_if: New module, borrowing ideas from netinet_in. * m4/net_if_h.m4: New file. * lib/net_if.in.h: Likewise. * doc/posix-headers/net_if.texi (net/if.h): Document it. * MODULES.html.sh (lacking POSIX:2008): Likewise. * tests/test-net_if.c: Make function checks conditional. Reported by Jasper Lievisse Adriaanse . 2012-09-05 Mats Erik Andersson (tiny change) readutmp: fix non-portable UT_PID use * lib/readutmp.c (desirable_utmp_entry) : Use `UT_PID (u) > 0' as absolute condition. 2012-09-04 Jim Meyering fts: reduce two or more trailing spaces to just one, usually * lib/fts.c (fts_open): Upon initialization, if a name ends in two or more slashes, trim all but the final one. But if a name consists solely of two slashes, don't modify it. If it consists solely of three or more slashes, strip all but one. This is part of the solution to a minor problem with rm: it would print a bogus ELOOP diagnostic when failing to remove the slash-decorated name of a symlink-to-directory: $ mkdir d && ln -s d s && env rm -r s/ rm: cannot remove 's': Too many levels of symbolic links With the change below and a trivial don't-trim-trailing-slashes adjustment to remove.c, it does this: $ env rm -r s/ rm: cannot remove 's/': Not a directory Improved by: Eric Blake fts: when there is no risk of overlap, use memcpy, not memmove * lib/fts.c (fts_alloc): Fix unjustified memcopy: s/memmove/memcpy/ 2012-08-29 Paul Eggert stdbool: be more compatible with mixed C/C++ compiles * lib/stdbool.in.h (_Bool, true, false) [__cplusplus]: Define to bool, true, false, respectively, as GCC's builtin stdbool.h does. Problem reported by Michael Goffioul in . 2012-08-28 Jim Meyering revert last change: it was not needed * tests/test-vc-list-files-git.sh: There's already a test for a working git, just below. 2012-08-28 Jim Meyering tests: test-vc-list-files-git.sh: skip if git is not available * tests/test-vc-list-files-git.sh: Skip this test when git is not available. 2012-08-26 Bruno Haible gnulib-tool: Remove no-op option --no-changelog. * gnulib-tool (func_usage): Don't mention --no-changelog. (do_changelog): Remove variable. Reported by Dmitriy Selyutin . 2012-08-24 Paul Eggert doc: remove fdl-1.2.texi It is no longer used or maintained, and its use of @acronym is problematic. See the thread containing . * config/srclist.txt: Remove doc/old-licenses/fdl-1.2.texi. * doc/old-licenses/fdl-1.2.texi: Remove. execinfo: port to FreeBSD * m4/execinfo.m4 (gl_EXECINFO_H): Set LIB_EXECINFO to -lexecinfo if needed, as in FreeBSD. Reported by Bastien Roucariès in . * modules/execinfo (Link): Add $(LIB_EXECINFO). 2012-08-23 Jim Meyering xstrtol.h: avoid "_Noreturn is not at beginning of declaration" warning * lib/xstrtol.h: Put "_Noreturn" before "void" in declaration, to placate gcc's -Wold-style-declaration. 2012-08-24 Paul Eggert doc: do not use @acronym * doc/inet_ntoa.texi (inet_ntoa): * doc/parse-datetime.texi (Seconds since the Epoch) (Specifying time zone rules): * doc/posix-functions/inet_ntoa.texi (inet_ntoa): Don't use @acronym. Problem reported by John Darlington in . 2012-08-23 Paul Eggert stdnoreturn: port to newer GCCs * m4/stdnoreturn.m4 (gl_STDNORETURN_H): Avoid problems with bleeding-edge GCC that complains about 'int _Noreturn foo (void);'. Problem reported by Jim Meyering in . Also, rename the 'test' function to a void a clash with the already-supplied 'main' function; this fixes a bug that incorrectly rejected GCC 4.7.1's . * doc/posix-headers/stdnoreturn.texi (stdnoreturn.h): Document GCC problem. 2012-08-22 Reuben Thomas pipe-filter: fix comment typo * lib/pipe-filter.h: Mention correct function. 2012-08-22 Paul Eggert execinfo: new module This is for Emacs. Currently, it provides a no-effect stub on all platforms where it does not already work. It already works on glibc-based systems, and on Solaris 11. * lib/execinfo.c, lib/execinfo.in.h, m4/execinfo.m4, modules/execinfo: New files. * doc/glibc-headers/execinfo.texi (execinfo.h): * MODULES.html.sh (Misc): Document it. 2012-08-20 Paul Eggert extern-inline: support old GCC 'inline' * m4/extern-inline.m4 (gl_EXTERN_INLINE): Use pre-C99 GCC 'inline' if available. This applies to GCC versions 2.7 through 4.2, or when newer GCC is using -fgnu89-inline. The goal is to address some of the performance issues mentioned by Bruno Haible in . 2012-08-20 Eric Blake maint.mk: avoid redundant file name in message * top/maint.mk (sc_prohibit_strcmp, sc_unmarked_diagnostics) (sc_prohibit_defined_have_decl_tests, sc_const_long_option) (sc_makefile_path_separator_check): Remove bogus $(ME). 2012-08-20 Mike Frysinger timer-time: fix link order when static linking on glibc * m4/timer_time.m4 (LIB_TIMER_TIME): Add -lpthread _after_ -lrt so that it's significant. 2012-08-19 Paul Eggert timespec: omit unnecessary AC_C_INLINE * m4/timespec.m4 (gl_TIMESPEC): Do not require AC_C_INLINE. stat-time: omit unnecessary AC_C_INLINE * m4/stat-time.m4 (gl_STAT_TIME, gl_STAT_BIRTHTIME): Do not require AC_C_INLINE. ignore-value: omit unnecessary AC_C_INLINE * modules/ignore-value (configure.ac): Do not require AC_C_INLINE. sys_select: avoid 'static inline' * lib/sys_select.in.h (rpl_fd_isset): Now static, not static inline. mktime: avoid 'static inline' * lib/mktime.c (leapyear, ydhms_diff): Now static, not static inline. * m4/mktime.m4 (gl_PREREQ_MKTIME): Do not require AC_C_INLINE. 2012-08-19 Bruno Haible gnulib-tool: Improve coding style. * gnulib-tool (func_emit_tests_Makefile_am): Set perhapsLT, like in func_emit_lib_Makefile_am. Reported and fix suggested by Dmitriy Selyutin . 2012-08-19 Bruno Haible gnulib-tool: Fix indentation. * gnulib-tool (func_import): Fix indentation. 2012-08-19 Bruno Haible gnulib-tool: Remove old file names from .cvsignore, .gitignore. * gnulib-tool (func_update_ignorelist): Don't use 'join -v 1' command on the list of removed files. 2012-08-17 Paul Eggert test-parse-datetime: avoid glibc leap-second glitch * tests/test-parse-datetime.c (main): Set TZ to US Eastern time with the 2012 rules. Problem reported by Bruce Dubbs in . 2012-08-14 Bruno Haible gnulib-tool: Fix indentation of generated gnulib-comp.m4 file. * gnulib-tool (func_emit_autoconf_snippet): Initialize indentation from argument. Reported and fix suggested by Dmitriy Selyutin . 2012-08-14 Eric Blake ldexp: relax license * modules/ldexp (License): Trivial relax, since the module only provides a permissively licensed m4 file. 2012-08-13 Bruno Haible gnulib-tool: Fix persistence of --witness-c-macro option. * gnulib-tool (func_import): Fix typo in emit of gl_WITNESS_C_MACRO. Reported by Dmitriy Selyutin . 2012-08-11 Eric Blake count-leading-zeros: use a lookup table on non-gcc compilers * lib/count-leading-zeros.h (count_leading_zeros_32): Use an alternate implementation, suggested by Jim Meyering. 2012-08-10 Eric Blake count-leading-zeros: new module * modules/count-leading-zeros: New module. * m4/count-leading-zeros.m4: New file. * lib/count-leading-zeros.h: Likewise. * modules/count-leading-zeros-tests: New test. * tests/test-count-leading-zeros.c: New file. * MODULES.html.sh (Integer arithmetic functions): Document it. 2012-08-07 Simon Josefsson Jim Meyering maintainer-makefile: Fix syntax error with dash. * top/maint.mk (sc_vulnerable_makefile_CVE-2009-4029): Quote arguments. (sc_vulnerable_makefile_CVE-2012-3386): Likewise. 2012-08-05 Jim Meyering extern-inline: also ignore -Wmissing-declarations * m4/extern-inline.m4: Also ignore -Wmissing-declarations, required with gcc-4.8.0-to-be. maint.mk: sc_prohibit_magic_number_exit: avoid new false positives * top/maint.mk (sc_prohibit_magic_number_exit): Also filter out matches for /error ?([^,]*)/. This avoids false-positives for strings like "Unknown error (252)", introduced via commit v0.0-7538-g92875a6. 2012-08-02 Stefano Lattarini gnumakefile: better interaction with Automake-NG * modules/gnumakefile [Makefile.am]: The makefiles generated by Automake-NG always contain a definition of VPATH, even in non-VPATH builds (its value being simply '.' in that case). So, in the 'clean-GNUmakefile' rule, to determine whether running under a VPATH setup, compare '$(srcdir)' to '.' rather than checking whether '$(VPATH)' expands to the empty string. 2012-08-02 Carlo de Falco (tiny change) base64: Use extern C scope in header file, for C++. * lib/base64.h: Add C++ namespace protection. 2012-08-02 Paul Eggert stat-time, timespec, u64: support naive out-of-dir builds * lib/stat-time.c, lib/timespec.c, lib/u64.c: Use '#include "foo.h"', not '#include ', when including one's own interface. This works better when configuring with out-of-directory builds, since packages need not add an otherwise-unnecessary -I$(topdir_src)/lib to DEFAULT_INCLUDES. 2012-08-01 Paul Eggert utimens: use extern-inline * lib/utimens.c (_GL_UTIMENS_INLINE): Define when including utimens.h. * lib/utimens.h: Add copyright notice, since this is now large enough to copyright. Use _GL_INLINE_HEADER_BEGIN, _GL_INLINE_HEADER_END. (_GL_UTIMENS_INLINE): New macro. Use it instead of 'static inline'. * modules/utimens (Depends-on): Add extern-inline. u64: use extern-inline * lib/u64.c: New file. * lib/u64.h: Use _GL_INLINE_HEADER_BEGIN, _GL_INLINE_HEADER_END. (_GL_U64_INLINE): New macro. Use it instead of 'static inline'. * modules/u64 (Files): Add lib/u64.c. (Depends-on): Add extern-inline. (configure.ac): No need to require AC_C_INLINE, since extern-inline does that now. (lib_SOURCES): Add u64.c. timespec: use extern-inline * lib/timespec.c: New file. * lib/timespec.h: Use _GL_INLINE_HEADER_BEGIN, _GL_INLINE_HEADER_END. (_GL_TIMESPEC_INLINE): New macro. Use it instead of 'static inline'. * modules/timespec (Files): Add lib/timespec.c. (Depends-on): Add extern-inline. (lib_SOURCES): Add timespec.c. stat-time: use extern-inline * lib/stat-time.c: New file. * lib/stat-time.h: Use _GL_INLINE_HEADER_BEGIN, _GL_INLINE_HEADER_END. (_GL_STAT_TIME_INLINE): New macro. Use it instead of 'static inline'. * modules/stat-time (Files): Add lib/stat-time.c. (Depends-on): Add extern-inline. (lib_SOURCES): Add stat-time.c. extern-inline: new module * modules/extern-inline, m4/extern-inline.m4: New files. This is for better support of 'extern inline' a la ISO C99, with a portable alternative on compilers that do not support C99-style 'extern inline'. Using 'extern inline' shrinks the size of the Emacs executable, when compiled with debugging disabled, which is a typical way that Emacs is built while developing. 2012-08-01 Akim Demaille maint.mk: a "release-commit" wrapper to do-release-commit-and-tag * build-aux/do-release-commit-and-tag: Move variable definitions together. ($branch): Instead of defaulting to "master", default to the current branch (as gnu-web-doc-update does). (help): Display the current values of the option arguments. * top/maint.mk (release-commit): New. * top/README-release: Simplify the corresponding step. 2012-07-30 Eric Blake passfd: fix comment on recvfd * lib/passfd.c (recvfd): Fix comment. Reported by Jann Horn . 2012-07-30 Jim Meyering maint.mk: avoid a sub-shell * top/maint.mk (release-prep): Remove unneeded sub-shell. 2012-07-30 Akim Demaille maint.mk: use silent-rules support from Automake * top/maint.mk (news-check, vc-diff-check, announcement) (no-submodule-changes, alpha beta stable, release-prep) (web-manual, update-copyright): Use $(AM_V_GEN) and $(AM_V_at). 2012-07-30 Akim Demaille maint.mk: provide a web-manual-update target * top/maint.mk: here. * top/README-release: Use it to simplify the web manual update step. 2012-07-30 Akim Demaille README-release: shorten the circuit to post a news * top/README-release: Point directly to the news submission form. 2012-07-30 Akim Demaille gnu-web-doc-update: fix --help * build-aux/gnu-web-doc-update: The information "top level" was written twice. 2012-07-30 Akim Demaille maint.mk: absolute VPATH issue * top/maint.mk (release-prep): Help Git find .git/. From Jim Meyering. 2012-07-29 Akim Demaille gitlog-to-changelog: fix previous change * build-aux/gitlog-to-changelog: Fix condition. Add missing ";". 2012-07-29 Akim Demaille gitlog-to-changelog: don't expect .git to be in $srcdir Reported by Bruno Haible. * build-aux/gitlog-to-changelog (&git_dir_option): New. Use it. 2012-07-29 Akim Demaille maint.mk: absolute VPATH build fix * top/maint.mk (gpg_key_ID): Help git find .git when, for instance, $(srcdir) is not a parent of $(builddir). 2012-07-28 John Darrington clean-temp: Fix memory leak. * lib/clean-temp.c (cleanup_temp_dir): Free also the 'subdirs' and 'files' members of tmpdir. 2012-07-27 Jim Meyering maint.mk: new rule: refresh-gnulib-patches I noticed that 8 of coreutils' 9 gl/**/*.diff files were stale. Use this rule to refresh them. * top/maint.mk (refresh-gnulib-patches): New rule. 2012-07-24 Bruno Haible gnulib-tool: Fix handling of inctests variable. * gnulib-tool: Canonicalize $inctests also in 'update' mode. Reported by Nick Bowler . 2012-07-22 Bruno Haible getpass: Assume AC_CHECK_DECLS_ONCE invocation, like in getpass.m4. * lib/getpass.h: Assume HAVE_DECL_GETPASS is defined. * cfg.mk (exclude_file_name_regexp--sc_prohibit_defined_have_decl_tests): Remove exemption for getpass.h. Suggested by Eric Blake. 2012-07-20 Eric Blake verify: document conflict with -Wnested-externs * lib/verify.h: Give hint about usage when gcc warnings are enabled. maint.mk: forbid exit(-1) * top/maint.mk (sc_prohibit_magic_number_exit): Detect negatives. 2012-07-20 Paul Eggert fsusage: port back to Solaris * lib/fsusage.c (get_fs_usage): Fix busted logic causing compile-time error (fsd not declared) on Solaris 10. Reported privately by Andrew Borodin. 2012-07-19 Akim Demaille gnu-web-doc-update: fix error messages * build-aux/gnu-web-doc-update: Don't pass $ME to die. gnu-web-doc-update: check the requirements. * build-aux/gnu-web-doc-update (find_tool): Import from bootstrap. ($CVS, $CVSU, $GIT, $RSYNC, $XARGS): New. * build-aux/bootstrap (find_tool): Comment change. 2012-07-17 Akim Demaille maint.mk: minor simplication. * top/maint.mk (_sc_excl): Use $(or...) instead of $(if...) for default values. 2012-07-15 Akim Demaille gitlog-to-changelog: VPATH build issues If builddir is not a subdirectory of srcdir, running git from it will fail. * build-aux/gitlog-to-changelog (--srcdir): New option. 2012-07-15 Bruno Haible fpending: Assume AC_CHECK_DECLS_ONCE invocation, like in fpending.m4. * lib/fpending.h: Assume HAVE_DECL___FPENDING is defined. * cfg.mk (exclude_file_name_regexp--sc_prohibit_defined_have_decl_tests) Remove exemption for fpending.h. Suggested by Eric Blake. 2012-07-15 Paul Eggert pthread_sigmask: fix bug on FreeBSD 9 * lib/pthread_sigmask.c [PTHREAD_SIGMASK_INEFFECTIVE]: Include string.h. (pthread_sigmask) [PTHREAD_SIGMASK_INEFFECTIVE]: When calling pthread_sigmask (1729, NEW, OLD), specify non-null NEW; this avoids a bug on FreeBSD 9, where pthread_sigmask is effective but pthread_sigmask (1729, NULL, NULL) returns zero. See . Avoid the need to call pthread_sigmask (1729, ...) in most cases, by inspecting whether the main call changed the old mask. 2012-07-15 Reuben Thomas README-release: make it more legible * top/README-release: Improve typography slightly. 2012-07-15 Jim Meyering maint: require that each sc_... command start with "@" * Makefile (sc_prohibit_sc_omitted_at): New rule so that "make sc_maint" helps us avoid this nit. 2012-07-15 Jim Meyering maint.mk: add leading "@" to quiet new "make syntax-check" rule * top/maint.mk (sc_prohibit_defined_have_decl_tests): Add "@". 2012-07-13 Eric Blake maint.mk: new syntax check for HAVE_DECL checks * top/maint.mk (sc_prohibit_defined_have_decl_tests): New rule. * cfg.mk (exclude_file_name_regexp--sc_prohibit_defined_have_decl_tests): Exempt some false positives. Based on a report by Karel Zak. argp: make HAVE_DECL usage consistent * lib/argp-parse.c (__argp_parse): Check contents of HAVE_DECL macros, not whether they are defined. * m4/argp.m4 (gl_ARGP): Always define HAVE_DECL_* macros, per convention with other declaration checks. Reported by Karel Zak, with suggestions from Paul Eggert. stat-time: relax license to LGPLv2+ * modules/stat-time (License): Relax, with consent of all authors. strndup: fix m4 usage error * m4/strndup.m4 (gl_FUNC_STRNDUP): HAVE_DECL_STRNDUP is always defined, to either 0 or 1. Reported by Karel Zak. 2012-07-11 Jim Meyering maint: enable the sc_avoid_if_before_free syntax-check rule * cfg.mk (local-checks-to-skip): Enable sc_avoid_if_before_free. (if_before_free_offenders_): Define. (if_before_free_basename_re_): Define. Exempt current files with useless if-before-free. 2012-07-11 Paul Eggert gettext: do not assume '#define ... defined ...' behavior * lib/gettext.h (_LIBGETTEXT_HAVE_VARIABLE_SIZE_ARRAYS): Do not use '#define FOO ... defined BAR ...', as the C standard says it's not portable to expect that this works after macro expansion. Problem reported for gzip by Steven M. Schweda in . 2012-07-10 Paul Eggert getloadavg: clean out old Emacs and Autoconf cruft See Glenn Morris in . * lib/getloadavg.c: Include , always. Include if HAVE_SYS_PARAM_H, not if unix or __unix. (LDAV_CVT): Remove no-longer-used LOAD_AVE_CVT hook. * m4/getloadavg.m4 (gl_PREREQ_GETLOADAVG): Check for . 2012-07-10 Akim Demaille bootstrap: let warn be like tests/init.sh's warn_ Reported by Jim Meyering. * build-aux/bootstrap (warn): Remove, replaced by... (warnf_, warn_): these. Adjust callers. Shorten messages that no longer fit in 80 columns. 2012-07-09 Bruno Haible getopt: Simplify after Emacs changed. * m4/getopt.m4 (gl_FUNC_GETOPT_POSIX): Inline gl_GETOPT_IFELSE. (gl_GETOPT_IFELSE): Remove macro. 2012-07-09 Jim Meyering maint.mk: add sc_vulnerable_makefile_CVE-2012-3386 * top/maint.mk (sc_vulnerable_makefile_CVE-2012-3386): New rule. maint.mk: _sc_search_regexp, sc_vulnerable_makefile_CVE-2009-4029: fix Bugs in both of those conspired to make the sc_vulnerable_makefile_CVE-2009-4029 rule 99% useless. _sc_search_regexp's handling of non-empty $in_files would filter out any offending file names. sc_vulnerable_makefile_CVE-2009-4029's choice of in_files value meant there would be no match in most projects, due to the presence of two or more Makefile.in files. * top/maint.mk (_sc_search_regexp) [in_vc_files,in_files]: Clarify. Fix a bug in how a non-empty $$in_files was processed: (sc_vulnerable_makefile_CVE-2009-4029): Fix erroneous use of in_files: in spite of the name, it's a regexp, not a list of file names. 2012-07-09 Paul Eggert getloadavg, getopt: fix commentary re configure.in Autoconf is deprecating the name 'configure.in', so change it to to the new name 'configure.ac' in a couple of places. * lib/getloadavg.c: configure.in -> configure.ac, in comment. * m4/getopt.m4 (gl_GETOPT_IFELSE, gl_GETOPT_SUBSTITUTE_HEADER) (gl_PREREQ_GETOPT): Remove obsolete commentary re Emacs configure.in. Emacs has renamed it to configure.ac, and it no longer refers to these macros anyway. timespec: mark functions with const attributes * lib/timespec.h (timespec_add, timespec_sub, dtotimespec): Mark with _GL_ATTRIBUTE_CONST. 2012-07-07 Ludovic Courtès canonicalize[-lgpl]: handle "guessing" values when cross-building * m4/canonicalize.m4 (gl_FUNC_CANONICALIZE_FILENAME_MODE) (gl_CANONICALIZE_LGPL): Check whether $gl_cv_func_realpath_works matches "*yes" instead of just "yes". Regression introduced in commit e0bcf6626cde8dad4bfbdc4045c744f0cd8b9e24. 2012-07-07 Ludovic Courtès Bruno Haible canonicalize: make the right guess when cross-compiling to GNU * m4/canonicalize.m4 (gl_FUNC_REALPATH_WORKS): Match also "gnu*" to determine whether cross-compiling to glibc systems, so as to include GNU/Hurd. 2012-07-06 Paul Eggert timespec-sub: avoid duplicate include * lib/timespec-sub.c: Do not include twice. Reported by Juanma Barranquero. 2012-07-06 Akim Demaille bootstrap: use a more consistent error reporting scheme * build-aux/bootstrap (warn, die): New. Use them. 2012-07-05 Paul Eggert sys_time: allow too-wide tv_sec * m4/sys_time_h.m4 (gl_HEADER_SYS_TIME_H_BODY): Allow struct timeval even if tv_sec is wider than time_t. This allows OpenBSD 5.1 amd64 and fixes an Emacs porting glitch with utimens.c, as without this patch gnulib replaces struct timeval and OpenBSD futimes therefore has a type mismatch. * doc/posix-headers/sys_time.texi: Mention this. pthread: check for both pthread_create and pthread_join * m4/pthread.m4 (gl_PTHREAD_CHECK): Revert previous change, but alter the check so that it tests for both pthread_create and pthread_join. This should be more portable to hosts like OSF/1 5.1. Suggested by Bruno Haible and Richard Yao in . parse-datetime: doc tuneup * doc/parse-datetime.texi: Index "leap seconds" and fix minor spacing issues. 2012-07-05 Akim Demaille do-release-commit-and-tag: fix the previous commit * build-aux/do-release-commit-and-tag: Actually the test was right, but the comment and the error message were misleading. Fix comment, and improve error message. Perform check first, so that NEWS is not modified uselessly. do-release-commit-and-tag: fix typo * build-aux/do-release-commit-and-tag: Be sure that NEWS does _not_ start with a stub. 2012-07-04 Paul Eggert pthread: check for pthread_create, not pthread_join * m4/pthread.m4 (gl_PTHREAD_CHECK): Check for pthread_create, not pthread_join. On FreeBSD 9, pthread_create is in libpthread but pthread_join in libc. I hope this removes the need for all the OSF/1 5.1 pthread_join business. Reported by Richard Yao in . 2012-07-04 Jim Meyering parse-datetime: fix failure to diagnose invalid input date -d "$(printf '\xb0')" would print 00:00:00 with today's date rather than diagnosing the invalid input. Now it reports this: date: invalid date '\260' * lib/parse-datetime.y (to_uchar): Define. (yylex): Don't sign-extend "other" bytes. * m4/parse-datetime.m4: Require AC_C_INLINE for first use of "inline". Thanks to Bruno Haible for the patch to this file. * tests/test-parse-datetime.c (main): Add a test to trigger the bug. Peter Evans reported the bug in GNU date: http://bugs.gnu.org/11843 2012-07-03 Jim Meyering bootstrap: do not require now-removed build-aux/missing Now that build-aux/missing is, er, missing, bootstrap would silently fail. * build-aux/bootstrap (gnulib_extra_files): Remove $build_aux/missing from the list, now that (since commit v0.0-7489-gd0f486f) the file is no longer part of gnulib. Diagnose the failure. 2012-07-03 Paul Eggert alloca: add support for HP NonStop TNS/E native * lib/alloca.in.h (alloca): Support the new host. From a suggestion by Joachim Schmitz in . 2012-07-02 Pádraig Brady fsusage: remove code not needed on non GNU/Linux systems. * lib/fsusage.c [STAT_STATVFS || STAT_STATVFS64]: Don't include headers no longer needed in this case. * lib/fsusage.c [STAT_STATVFS && ! (__linux__ && (__GLIBC__||__UCLIBC__))]: Undefine STAT_STATFS2_FRSIZE to exclude code not used in this case. 2012-07-02 Paul Eggert fsusage: include files needed for glibc 2.6 fallback * lib/fsusage.c [STAT_STATVFS || STAT_STATVFS64]: Include , , as they are needed for the 2.6 < glibc/Linux < 2.6.36 fallback. Problem reported by Ludovic Courtès in . fsusage: avoid needless check on GNU/Linux * m4/fsusage.m4 (gl_FILE_SYSTEM_USAGE): Omit STAT_STATFS3_OSF1 check on GNU/Linux systems, since it can't possibly work. 2012-07-01 Bruno Haible log: Fix an autoconf >= 2.64 warning. * modules/log (configure.ac): Require, not invoke, gl_FUNC_LOG. Reported by Carlos O'Donell . 2012-06-28 Bruno Haible log10f: Fix possible configuration problem. * m4/log10f.m4 (gl_FUNC_LOG10F): Augment LIBS by $LOG10F_LIBM, not $LOGF_LIBM. Reported by Carlos O'Donell . 2012-06-28 Bruno Haible remove: No longer override on all platforms. Fixes bug from 2010-03-20. * m4/remove.m4 (gl_FUNC_REMOVE): Test gl_cv_func_unlink_honors_slashes, not gl_cv_func_unlink_works. Reported by Carlos O'Donell . 2012-06-27 Eric Blake config: drop scripts that automake says are not independent * config/srclist.txt: Drop elisp-comp, missing, and ylwrap. * build-aux/elisp-comp: Delete. * build-aux/missing: Likewise. * build-aux/ylwrap: Likewise. * modules/elisp-comp: Likewise. * MODULES.html.sh: Drop mention of elisp-comp. * NEWS: Mention this. 2012-06-26 Paul Eggert root-uid: new module This is for portability to Tandem's NonStop Kernel. * lib/root-uid.h, modules/root-uid: New files. * lib/euidaccess.c, lib/pt_chown.c, lib/unlinkdir.c: * lib/write-any-file.c, tests/test-sethostname2.c: Include "root-uid.h". * lib/euidaccess.c (euidaccess): * lib/pt_chown.c (main): * lib/unlinkdir.c (cannot_unlink_dir): * lib/write-any-file.c (can_write_any_file): * m4/mknod.m4 (gl_FUNC_MKNOD): * tests/test-sethostname2.c (geteuid, main): Don't assume ROOT_UID == 0. * modules/euidaccess (Depends-on): * modules/pt_chown (Depends-on): * modules/sethostname-tests (Depends-on): * modules/unlinkdir (Depends-on): * modules/write-any-file (Depends-on): Add root-uid. regex: use locale-independent comparison for codeset name See Bruno Haible's comment in . * lib/regcomp.c (init_dfa): Use just ASCII case comparison for codeset name. * lib/regex_internal.h: Do not include , since we no longer use strcasecmp. * modules/regex (Depends-on): Remove strcase. 2012-06-23 Bruno Haible getopt-posix: No longer guarantee that option processing is resettable. * doc/posix-functions/getopt.texi: Drop description of problem with internal state. Fix info about mingw and msvc9. * m4/getopt.m4 (gl_GETOPT_CHECK_HEADERS): Don't require a resettable option processing by getopt(). Run three test programs instead of one. Simplify cross-compilation guess. * NEWS: Mention the change. Reported by Rich Felker . 2012-06-26 Bruno Haible argp, regex: Ensure strcasecmp gets declared. * lib/argp-help.c: Include . * lib/regex_internal.h: Likewise.

Revamp the handling of options. Prefer $(...) to `...`. Don't pass --tmpdir=. to mktemp, it is useless given that we specify the template, and it is GNU mktemp specific. Prefer set -e to long series of &&. Restore the initial git branch, not "master". Properly initialize submodules (don't rely only on bootstrap). Do not reconfigure blindly, use config.status. * top/README-release: Update instructions for gnu-web-doc-update. 2012-06-11 Jim Meyering maint.mk: revert most of the previous change re "all these" * top/maint.mk (prohibit_undesirable_word_seq_RE_): Remove that pair. For rationale, see the discussion at http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/30912 2012-06-10 Karl Berry * build-aux/gnupload: with --dry-run, do not ask for gpg pw. * build-aux/gnupload: implement --replace, ftp-upload protocol v1.2. 2012-06-10 Bruce Korb parse-duration: Relicense under LGPLv2+. * modules/parse-duration (License): Change to LGPLv2+. 2012-06-10 Jim Meyering maint.mk: prohibit common grammar error: "all these" * top/maint.mk (prohibit_undesirable_word_seq_RE_): Add "all these" to the list of prohibited word sequences. It should be "all of these". * lib/tempname.c (__gen_tempname): Fix one of them. 2012-06-07 Akim Demaille do-release-commit-and-tag: support VPATH builds * build-aux/do-release-commit-and-tag: Prefer $(...) to `...`. (noteworthy): Defined earlier to factor its value. (noteworthy_stub): New. Use it to factor. (help_version): Split into... (help, version): these. Adjust the option processing part. Support "--option=value" in addition to "--option value". (builddir): New. (--builddir): New option. * top/README-release: Document this. Reword slightly so that the reader cannot understand that he has to do these steps before calling do-release-commit-and-tag. 2012-06-07 Akim Demaille readme-release: also require announce-gen and maintainer-makefile * modules/readme-release (Depends-on): here. * modules/announce-gen, modules/do-release-commit-and-tag, modules/gnu-web-doc-update, modules/maintainer-makefile (Description): Point to readme-release. 2012-06-07 Akim Demaille maint.mk: fix VPATH issues. * top/maint.mk (news-check): GNU Make understand $< very well. (release-prep): NEWS is in $(srcdir). 2012-06-05 Akim Demaille readme-release: require the promoted modules. * modules/readme-release (Depends-on): Add do-release-commit-and-tag, gnupload, and gnu-web-doc-update, used in this text. 2012-05-21 Paolo Bonzini Bruno Haible error, strerror-override: Support mingw64 from Fedora 17. * lib/errno.in.h (GNULIB_defined_ESTREAMS): Use a different indicator for ETXTBSY, ENODATA, ENOSR, ENOSTR, ETIME, EOTHER, compared to EINPROGRESS. * lib/strerror-override.h (strerror_override): Test it. * lib/strerror-override.c (strerror_override): Likewise. * m4/errno_h.m4 (gl_HEADER_ERRNO_H): Test also ETXTBSY. 2012-05-21 Paolo Bonzini Bruno Haible error, strerror-override: Support mingw64 from Fedora 17. * lib/errno.in.h (GNULIB_defined_ENOTRECOVERABLE): Use a different indicator for ENOTRECOVERABLE, compared to EOWNERDEAD. * lib/strerror-override.h (strerror_override): Test it. * lib/strerror-override.c (strerror_override): Likewise. 2012-06-03 Bruno Haible error, strerror-override: Support new errno values from POSIX:2008. * m4/errno_h.m4 (gl_HEADER_ERRNO_H): Test also EOWNERDEAD and ENOTRECOVERABLE. * lib/errno.in.h (EOWNERDEAD, ENOTRECOVERABLE): Define on all platforms. * lib/strerror-override.c (strerror_override): Conditionalize the EOWNERDEAD, ENOTRECOVERABLE handling on GNULIB_defined_EOWNERDEAD. * lib/strerror-override.h (strerror_override): Declare also if GNULIB_defined_EOWNERDEAD is defined. * tests/test-errno.c (e130, e131): New variables. * doc/posix-headers/errno.texi: Mention the status for EOWNERDEAD, ENOTRECOVERABLE. Reported by Paolo Bonzini. 2012-05-31 Jim Meyering savewd: add missing dependency on sys_wait module * modules/savewd (Depends-on): Add sys_wait, needed at least for MSVC. Report and suggested change by Michael Goffioul. 2012-05-29 Paul Eggert system-quote-tests: port to CentOS 5 Problem reported by Tom G. Christensen in . * tests/test-system-quote-child.c (fclose, fprintf): Undef. 2012-05-29 Jim Meyering maint: fix typos in comments and ChangeLog Culprits identified and fixed mostly automatically using these commands: git ls-files | misspellings -f - |grep -v '^ERROR:' |perl -pe \ 's/^(.*?)\[(\d+)\]: (\w+) -> "(.*?)"$/sed -i '\''${2}s!$3!$4!'\'' $1/' using http://github.com/lyda/misspell-check * ChangeLog: Fix typos. * doc/solaris-versions: Likewise. * lib/regexec.c (re_search_stub): Likewise. * m4/mmap-anon.m4 (gl_FUNC_MMAP_ANON): Likewise. 2012-05-27 Paul Eggert manywarnings: remove duplicate -Wmultichar entry * m4/manywarnings.m4 (gl_MANYWARN_ALL_GCC): Remove duplicate entry for -Wmultichar. -Wno-multichar is in the GCC 4.7.0 manual, so keep the entry marked as documented. 2012-05-27 Karl Berry * config/srclist.txt (mktime.c): remove last libc sync, perhaps just temporarily. 2012-05-26 Paul Eggert regex: don't assume uint64_t or uint32_t * lib/regcomp.c (init_word_char): Don't assume that the types uint64_t and uint32_t exist. The C standard doesn't guarantee them, and on some 32-bit compilers there is no uint64_t. Problem reported by Gianluigi Tiesi in . 2012-05-25 Jim Meyering maint.mk: add strncpy-prohibiting syntax-check rule * top/maint.mk (sc_prohibit_strncpy): New rule, from coreutils. 2012-05-24 Jim Meyering maint.mk: compute $(gpg_key_ID) more portably * top/maint.mk (gpg_key_ID): Use awk in place of sed '{...;...;}'. That use of sed is not portable to some fringe systems. Reported by Paul Eggert in http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/30793/focus=30802 2012-05-23 Paul Eggert mktime: sync from glibc * config/srclist.txt: Uncomment mktime.c. * lib/mktime.c: Sync from glibc master. This incorporates 3 changes. First, indent with tabs, since glibc uses tabs and doesn't want to change and we'd rather be identical to glibc. Also, two small coding changes: (isdst_differ): Use &&, not &, as && is the usual style. (__mktime_internal): Rename local var from abs_diff to approx_abs_diff for clarity. 2012-05-23 Akim Demaille announce-gen: du -h is more portable than du --human * build-aux/announce-gen (sizes): Invoke du with -h instead of --human. Accept leading white space in its output. 2012-05-23 Akim Demaille announce-gen: Improve diagnostics. * build-aux/announce-gen: When parsing command line options, prefer "announce-gen: option --release-type requires an argument" to "Option release-type requires an argument". 2012-05-23 Akim Demaille maint.mk: gpg_key_ID: use sed more portably * top/maint.mk (gpg_key_ID): End sed block with a semicolon before the closing brace. (refresh-po): Fuse two sed invocations into one. 2012-05-15 Akim Demaille gitlog-to-changelog: support the log message format used in Bison. * build-aux/gitlog-to-changelog: Support --strip-tab and --strip-cherry-picked. 2012-05-21 Paolo Bonzini poll/select: prevent busy-waiting. SwitchToThread() only gives away the rest of the current time slice to another thread in the current process. So if the thread that feeds the file decscriptor we're polling is not in the current process, we get busy-waiting. * lib/poll.c: Use SleepEx(1, TRUE) instead of SwitchToThread(). Patch from Theodore Leblond. * lib/select.c: Split polling out of the loop that sets the output fd_sets. Check for zero result and loop if the wait timeout is infinite. 2012-05-21 Simon Josefsson select: Fix build error on IRIX 6.5. * lib/select.c: Include stddef.h for NULL. 2012-05-21 Simon Josefsson gc: fix libgcrypt detection on older machines. * m4/gc.m4: Reject libgcrypt earlier than 1.4.4. Collapse copyright years because the file has been distributed every year since it was created. 2012-05-18 Paul Eggert crypto: fix bug in large buffer handling Problem reported by Serge Belyshev for glibc in and for gnulib in . * lib/md4.c (md4_process_block): * lib/md5.c (md5_process_block): * lib/sha1.c (sha1_process_block): * lib/sha256.c (sha256_process_block): Don't assume the buffer length is less than 2**32. * lib/sha512.c (sha512_process_block): Likewise. Here, the bug is present only in the rare case where the host does not support uint64_t or where size_t is wider than 64 bits. Use u64size to work around the problems. * lib/u64.h (u64size): New macro. 2012-05-15 Pádraig Brady fsusage: fix block size returned on older Linux 2.6 * lib/fsusage.c: Fall back to (struct statfs).f_frsize which is available since Linux 2.6. * m4/fsusage.m4 (STAT_STATFS2_FRSIZE): Always define when the member is available so it can be used as a fallback. * doc/posix-functions/statvfs.texi: Mention the hang issue on Linux < 2.6.36. 2012-05-14 Paul Eggert bootstrap: suppress stderr chatter * build-aux/bootstrap (insert_sorted_if_absent, main program): Omit unnecessary chatter to stderr. The main program chatter was there only inadvertantly. bootstrap: .gitignore files created by autopoint, libtool I ran into this problem when bootstrapping the latest diffutils. After './bootstrap', 'git status' reported lots of untracked files m4/codeset.m4, m4/gettext.m4, etc. These files were created by autopoint and do not need to be version-controlled. * build-aux/bootstrap: Put into .gitignore the files that autopoint and libtool create, by keeping track of files that exist after but not before these programs are run. (version_controlled_file): Move up. 2nd arg is now full file name, not base name; this is more convenient. Put CVS at the end, as it's now somewhat deprecated. 2012-05-14 Jim Meyering ignore-value.h: remove unused _GL_ATTRIBUTE_DEPRECATED definition * lib/ignore-value.h (_GL_ATTRIBUTE_DEPRECATED): Remove now-unused definition. Reported by Bruno Haible. 2012-05-13 Bruno Haible Paul Eggert binary-io: Define set_binary_mode function. * lib/binary-io.h (set_binary_mode): New function. (SET_BINARY): Define in terms of set_binary_mode. * modules/binary-io (configure.ac): Require AC_C_INLINE. * tests/test-binary-io.c (main): Accept an argument, and test either set_binary_mode or SET_BINARY depending on the argument. * tests/test-binary-io.sh: Invoke test-binary-io twice, with an argument. Clean up also t-bin-out0.tmp. 2012-05-13 Stefano Lattarini bootstrap: take advantage of POSIX shell features The 'bootstrap' script offered by Gnulib script already uses POSIX shell features (like $((...)) arithmetic expansions) that are not supported by legacy Bourne shells like Solaris 10 /bin/sh. This means that bootstrap must already be run using a proper POSIX shell, which will thus provide more features, like ${var#pattern} parameter expansion or inversion of a command exit status with '!'. We can thus use these features to improve the clarity and the performances of the bootstrap script. Suggested by Eric Blake. * build-aux/bootstrap: Prefer xpg4 parameter expansions over use of sed/expr plus command substitutions, to save some forks. While we are at it, prefer the POSIX $(...) form of command substitution, rather than the legacy form `...` (since the former is visually clearer and interacts better with quoting), and prefer the idiom: "if ! CMD; then ACTION ..." over the idiom: "if CMD; then :; else ACTION ..." which was required by legacy Bourne shells not supporting '!'. 2012-05-12 Bruno Haible system-quote: Add more comments. * lib/system-quote.h: Add more comments about wilcards and limitations. Suggested by Eli Zaretskii . sh-quote, system-quote: Add comments about wildcards. * lib/sh-quote.h: Clarify what happens with wildcard characters. * lib/system-quote.h: Likewise. Reported by Eli Zaretskii . 2012-05-11 Paul Eggert fsusage: check for GNU/Linux statvfs problem dynamically * lib/fsusage.c [STAT_STATVFS && __linux__ && (__GLIBC__||__UCLIBC__)]: Define STAT_STATFS2_BSIZE too, since in this case the code now checks dynamically whether statvfs is reliable, falling back on Linux-style statfs otherwise. (statvfs_works): New function, for dynamically testing statvfs. (get_fs_usage) [STAT_STATVFS]: Use it. * m4/fsusage.m4 (gl_FILE_SYSTEM_USAGE): Remove static check for statvfs on GNU/Linux hosts, since it's now done dynamically. 2012-05-10 Bruno Haible system-quote, execute, spawn-pipe: Escape '?' on Windows. * lib/system-quote.c (SHELL_SPECIAL_CHARS, CMD_SPECIAL_CHARS): Add the '?' character. * lib/w32spawn.h (SHELL_SPECIAL_CHARS): Likewise. * tests/test-system-quote-main.c (check_all): Check also strings like "??????????". Reported by Eli Zaretskii . 2012-05-10 Paul Eggert _Noreturn: port config.h to gcc -Wundef * m4/gnulib-common.m4 (gl_COMMON_BODY): Check that __STDC_VERSION__ is defined before using it, for gcc -Wundef. Reported by Akim Demaille in . 2012-05-10 Bruno Haible system-quote: Refactor. * lib/system-quote.h (system_quote_copy): Fix comment. * lib/system-quote.c (windows_createprocess_quote, windows_cmd_quote): New functions, extracted from system_quote_copy. (system_quote_length, system_quote_copy): Use these functions. Reported by Paul Eggert. 2012-05-08 Bruno Haible execute, spawn-pipe: Escape '*' characters in arguments on Windows. * lib/w32spawn.h (SHELL_SPECIAL_CHARS): Add the '*' character. 2012-05-08 Bruno Haible Tests for module 'system-quote'. * modules/system-quote-tests: New file. * tests/test-system-quote.sh: New file. * tests/test-system-quote-main.c: New file. * tests/test-system-quote-child.c: New file. New module 'system-quote'. * lib/system-quote.h: New file. * lib/system-quote.c: New file. * modules/system-quote: New file. 2012-05-08 Bruno Haible sh-quote: Make C++ safe and allow multiple inclusion. * lib/sh-quote.h: Add double-inclusion guard. For C++, wrap function declarations in extern "C". 2012-05-08 Bruno Haible sh-quote tests: Make tests stricter. * tests/test-sh-quote.c (check_one): Check the return value of shell_quote_copy. (main): Check a string with a CR character. Check a string that contains UCHAR_MAX. 2012-05-08 Akim Demaille warnings.m4: provide a means to specify the program to compile. * m4/warnings.m4 (gl_COMPILER_OPTION_IF): New, extracted from... (gl_WARN_ADD): here. Use gl_AS_VAR_APPEND. Support an argument to specify the program to compile. (gl_WARN_ADD): Accept an argument to specify the program to compile. AC_SUBST the WARN_CFLAGS when they are used. * modules/warnings (configure.ac): Don't AC_SUBST WARN_CFLAGS, leave this to gl_WARN_ADD. 2012-05-08 Eric Blake doc: recommendations on gettext version * doc/gnulib-tool.texi (gettextize and autopoint): Document the choice between versions. * DEPENDENCIES (gettext): Cover both approaches. 2012-05-08 Jim Meyering init.sh: explain why EXEEXT support uses aliases rather than functions * tests/init.sh: Add a comment. init.sh: don't let bash aliases interfere with tests * tests/init.sh: Undefine any pre-defined aliases if the selected shell is bash. This avoids problems for those who alias standard commands to non-conforming uses, like those reported in http://bugs.gnu.org/11256. Suggested by Tim Mooney . 2012-05-07 Paul Eggert stdint: be more consistent with glibc, SunOS libc * lib/stdint.in.h (gl_int_fast8_t, gl_uint_fast8_t) (gl_int_fast16_t, gl_uint_fast16_t) (gl_int_fast32_t, gl_uint_fast32_t) (INT_FAST8_MIN, INT_FAST8_MAX, UINT_FAST8_MAX) (INT_FAST16_MIN, INT_FAST16_MAX, UINT_FAST16_MAX) (INT_FAST32_MIN, INT_FAST32_MAX, UINT_FAST32_MAX): Be consistent with glibc by default, and with SunOS 5.10 and later if __sun is defined. This lessens the likelihood of clashes if code compiled for older hosts is combined with code compiled for newer ones. Problem reported by Niels Möller in . 2012-05-07 Eric Blake isatty: relax license to LGPLv2+ * modules/isatty (License): Relax license. 2012-05-06 Paul Eggert stat-size: comment fix * lib/stat-size.h: Remove obsolete comment about indenting. 2012-05-06 Bruno Haible Tests for module 'sh-quote'. * modules/sh-quote-tests: New file. * tests/test-sh-quote.c: New file. 2012-05-06 Bruno Haible sh-quote: Improve shell_quote_argv's signature. * lib/sh-quote.h (shell_quote_argv): Make argument array a 'const *'. * lib/sh-quote.c (shell_quote_argv): Likewise. 2012-05-06 Paul Eggert stdint: document issues with int_fast8_t etc. * doc/posix-headers/stdint.texi (stdint.h): Say that other stdint.h substitutes may define these types differently.

The loop should be rewritten to terminate. - The acl (... GETACLNT ...) call is merely an optimization; its value is merely a hint as to how big to make the array. A better optimization is to avoid the acl (... GETACLNT ...) call entirely, and just guess a reasonably-big size, growing the size and trying again if it's not large enough. This guarantees termination, and saves a system call. * lib/acl-internal.h: Include .

(init_word_char): Work even if bitset words are not exactly 32 or 64 bits wide. Don't assume there are no padding bits. * lib/regex.c [_LIBC]: Do not include . [!_LIBC]: Add pragmas to ignore -Wsuggest-attributes=pure and -Wtype-limits. * lib/regex.h (__USE_GNU): Renamed from __USE_GNU_REGEX, to avoid needless disagreement with glibc. All uses changed. Define it to 1 only if _GNU_SOURCE, to match glibc. (_REG_RM_NAME): Remove; no longer needed, since the names in question are now all protected by __USE_GNU.

The problem is that parse_bracket_symbol is miscompiled, and it turns out it is because of an incorrect attribute on re_string_fetch_byte_case. Unlike re_string_peek_byte_case, this one is really not pure, it modifies memory (increments pstr->cur_idx), and with the pure attribute GCC assumed it doesn't and it cached the presumed value of regexp->cur_idx in a variable across the for (;; ++i) { if (i >= BRACKET_NAME_BUF_SIZE) return REG_EBRACK; if (token->type == OP_OPEN_CHAR_CLASS) ch = re_string_fetch_byte_case (regexp); else ch = re_string_fetch_byte (regexp); if (re_string_eoi(regexp)) return REG_EBRACK; if (ch == delim && re_string_peek_byte (regexp, 0) == ']') break; elem->opr.name[i] = ch; } 2011-11-29 Andreas Schwab * lib/regcomp.c (build_equiv_class): Fix access after end of search string in regex matcher. 2011-11-12 Ulrich Drepper * lib/regex_internal.c, lib/regex_internal.h: Fix warnings in regex. 2011-10-12 Ulrich Drepper * lib/regcomp.c (parse_branch): One more regex memory leak fixed. 2011-10-11 Ulrich Drepper * lib/regcomp.c (parse_branch, parse_sub_exp): More regex memory leak fixes and tests. (parse_sub_exp, parse_bracket_exp): Fix memory leak for some invalid regular expressions. 2011-05-28 Ulrich Drepper * lib/regex_internal.c, lib/regexec.c: Fix unnecessary overallocation due to incomplete character.

(primary_ioctl): If fd is not a valid handle, set errno to EBADF. 2012-02-04 Bruno Haible fsync: Avoid test failure on native Windows. * lib/fsync.c (fsync) [Windows]: Don't fail if the handle is merely read-only. 2012-02-04 Bruno Haible sys_select: Avoid syntax error on OpenBSD 5.0. * lib/sys_select.in.h [OpenBSD]: When /usr/include/pthread.h is currently being included, just include the system's . 2012-02-04 Bruno Haible sys_select: Avoid syntax error on OpenBSD 5.0. * lib/sys_select.in.h: Include only after the include_next , not before. Reported by Jiri B . 2012-02-04 Bruno Haible get-rusage-as, get-rusage-data tests: Avoid test failure with gcc-4.7. * tests/test-get-rusage-as.c (main): Assign the malloc() results to global variables. * tests/test-get-rusage-data.c (main): Likewise.

Reported by Jens Staal . 2012-02-02 Jim Meyering file-has-acl: suppress a warning from gcc -Wsuggest-attribute=const * lib/file-has-acl.c (file_has_acl): This function (for some #ifdefs) would evoke a new gcc warning. Given all of the #ifdefs, it is better not even to try to add the attribute. Instead, add a pragma to suppress the suggestion/warning. 2012-01-31 Karl Berry setstate doc: typo. * doc/posix-functions/setstate.texi (setstate): { not (. 2012-01-31 Bruno Haible popen: Make more robust on Windows. * lib/popen.c: On native Windows, use the _popen based code even if HAVE_POPEN is set. * doc/posix-functions/popen.texi: Mention necessity of COMSPEC environment variable on native Windows. 2012-01-30 Bruno Haible pclose: Fix typo. * lib/stdio.in.h (pclose): Fix typo in warning message. 2012-01-30 Bruno Haible doc about getlogin_r, setstate. * doc/posix-functions/getlogin_r.texi: List the incompatible declaration problem under "not fixed by gnulib". * doc/posix-functions/setstate.texi: Mention incompatible declaration problem on Solaris 11 and other platforms. 2012-01-30 Chuanchang Jia (tiny change) Bruno Haible poll tests: Make test more robust. * tests/test-poll.c: Include macros.h.

(stat) [mingw, msvc]: Redefine the symbol to which stat is defined, not stat itself. Reported by Marc-André Lureau . 2012-01-30 Bruno Haible wcwidth: Work around bug in UTF-8 locale on OpenBSD 5.0. * m4/wcwidth.m4 (gl_FUNC_WCWIDTH): Test also wcwidth of U+05B0. * doc/posix-functions/wcwidth.texi: Mention the OpenBSD 5.0 bug. 2012-01-29 Bruno Haible quotearg: Fix test failure on MacOS X 10.5. * tests/test-quotearg-simple.c: Include localcharset.h.

Instead, test whether the output contains some '@' character. 2012-01-28 Paul Eggert strtoimax: eliminate need for stdint.h, inttypes.h checks * m4/strtoimax.m4 (gl_FUNC_STRTOIMAX): Don't use gl_AC_HEADER_STDINT_H or gl_AC_HEADER_INTTYPES_H. This reduces the prerequisites for a recently-introduced strtoimax test. I guess this might cause strtoimax to be replaced when not strictly necessary on older hosts, but this shouldn't introduce any bugs and it should make Emacs 'configure' faster on typical modern hosts. Problem discovered when importing the latest gnulib to an Emacs test version. * modules/strtoimax (Files): Remove m4/stdint_h.m4, m4/inttypes_h.m4. 2012-01-28 Bruno Haible sys_time: Override 'struct timeval' on some native Windows platforms. * m4/sys_time_h.m4 (gl_HEADER_SYS_TIME_H_BODY): Test whether tv_sec has the right type.

(select, timeval): Undefine at the right place. * modules/select (Depends-on): Add sys_time. * doc/posix-headers/sys_time.texi: Mention the problem with tv_sec on some Windows platforms. Reported by Marc-André Lureau . 2012-01-28 Marc-André Lureau (tiny change) accept4, fcntl, socket modules: Avoid warnings on x86_64 mingw64. * lib/accept4.c (accept4): Use intptr_t to convert handle pointer to an integer. * lib/fcntl.c (dupfd): Likewise. * lib/w32sock.h (SOCKET_TO_FD): Likewise. 2012-01-28 Bruno Haible fcntl: Avoid compilation error on native Windows. * modules/fcntl (Depends-on): Add 'close'. 2012-01-28 Marc-André Lureau (tiny change) select, poll, isatty: Avoid warnings on x86_64 mingw64. * lib/select.c (IsConsoleHandle): Use intptr_t to convert handle pointer to an integer. * lib/poll.c (IsConsoleHandle): Likewise. * lib/isatty.c (IsConsoleHandle): Likewise. 2012-01-28 Jim Meyering doc: clarify README-release * top/README-release: Clarify: you should make a point to have the latest stable versions of build tools in your PATH, and the reference to buildreq is solely for its list of tool names, not for its minimal-functional version numbers. Prompted by discussion with Reuben Thomas and Gary V. Vaughan. maint.mk: use more readable (yet functionally equivalent) quoting It is common to quote a single quote in a single quoted string like this: '...'\''...'. Unless you know the idiom, that looks like gibberish, so prefer to double-quote the string when possible. Then you can use a more readable, lone single quote: "...'..." * top/maint.mk (sc_cast_of_argument_to_free): Quoting like this "don't" is more readable than the equivalent 'don'\''t'. (sc_cast_of_x_alloc_return_value): Likewise. (sc_cast_of_alloca_return_value): Likewise. (sc_makefile_path_separator_check): Similar: use ":" in '...', rather than '\'':'\''. 2012-01-27 Paul Eggert stdalign: relax _Alignof and tighten _Alignas test * m4/stdalign.m4 (gl_STDALIGN_H): Relax the _Alignof test, as it was too strict: alignof must divide offsetof, but it need not equal offsetof. Inspired by Joseph S. Myers's comment . Conversely, tighten the _Alignas test a bit, as the resulting alignment must be exactly 8. 2012-01-27 Bruno Haible stdalign: Document the last change. * doc/posix-headers/stdalign.texi: Mention GCC bug 52023. 2012-01-27 Paul Eggert stdalign: check that alignof and offsetof are consistent * m4/stdalign.m4 (gl_STDALIGN_H): Check for GCC bug 52023.

Myers in . This leaves lib/localcharset.c, m4/iconv.m4, and a confusing comment in m4/include_next.m4 as the only gnulib-maintained places that still refer to __STDC__. 2012-01-24 Bruno Haible havelib: Modern quoting. * build-aux/config.rpath: Quote 'like this', not `like this', as per the recent change to the GNU coding standards. 2012-01-24 Bruno Haible stdint: Improve support for Android. * lib/stdint.in.h: Test __ANDROID__, not __BIONIC__. Reported by Simon Josefsson . 2012-01-23 Paul Eggert doc: omit trailing empty lines from INSTALL etc. * doc/Makefile (INSTALL): Omit trailing empty lines. (INSTALL.ISO, INSTALL.UTF-8): Build from INSTALL, so that these also omit trailing empty lines. This simplifies the build procedure. 2012-01-23 Jim Meyering tests: avoid spurious warnings about gl_sockets_startup Fedora rawhide's gcc version 4.7.0 20120119 with -Wunused-value would warn about every use of "gl_sockets_startup (SOCKETS_1_1);" reporting a "statement with no effect". * tests/test-accept.c (main): Mark as "(void)". * tests/test-accept4.c (main): Likewise. * tests/test-bind.c (main): Likewise. * tests/test-connect.c (main): Likewise. * tests/test-getpeername.c (main): Likewise. * tests/test-getsockname.c (main): Likewise. * tests/test-getsockopt.c (main): Likewise. * tests/test-listen.c (main): Likewise. * tests/test-recv.c (main): Likewise. * tests/test-recvfrom.c (main): Likewise. * tests/test-send.c (main): Likewise. * tests/test-sendto.c (main): Likewise. * tests/test-setsockopt.c (main): Likewise. * tests/test-shutdown.c (main): Likewise. 2012-01-21 Bruno Haible locale-fr.m4: Fix for Android. * m4/locale-fr.m4 (gt_LOCALE_FR, gt_LOCALE_FR_UTF8): Avoid compilation failure of the test program on Bionic libc. 2012-01-21 Jim Meyering bootstrap: fail when bootstrap_post_import_hook fails Otherwise, it's far too easy to miss diagnostics emitted between gnulib-tool's output and that of running configure. * build-aux/bootstrap: Fail when bootstrap_post_import_hook fails. 2012-01-17 Jim Meyering maint: enable sc_trailing_blank * build-aux/pmccabe.css: Remove trailing blanks. * doc/acl-cygwin.txt: Likewise. * doc/gnu-oids.texi: Likewise * cfg.mk: Enable sc_trailing_blank.

Drop the suggestion to translators about these two, and provide it automatically for Unicode locales. Like most programs, even those using American English, we use single quotation marks. This conflicts with the American typographic convention, but works better when you cite the entire error message within double quotes. It also tries not to clash with established practice and with what non-gnulib programs will usually do. * lib/quotearg.c (gettext_quote): Hard-code U+2018 and U+2019 when using an UTF-8 or GB-18030 locale.

Rationale: Microsoft renamed the "Win32 API" to "Windows API", as it is available on both 32-bit and 64-bit Windows systems. But in gnulib, we treat Cygwin like a Unix platform, therefore the main line of distinction is between "native Windows" on one side and Unix/ POSIX systems on the other side. More details in . Suggested by Paul Eggert. 2012-01-03 Bruno Haible isatty: Support for MSVC 9. * doc/posix-functions/isatty.texi: Mention the MSVC problem. * lib/isatty.c: Include , msvc-inval.h.

(configure.ac): Invoke gl_PREREQ_ISATTY. 2012-01-03 Jim Meyering maint.mk: remove temporary transition aid from over 1.5 years ago * top/maint.mk (_prohibit_regexp): Remove definition whose sole purpose was to aid in the transition (avoiding silent malfunction) from that old name to the new _sc_search_regexp. This shim was added by commit 219c504b. init.sh: do not try to accommodate compare arguments starting with "-" * tests/init.sh (compare_dev_null_): Do not try to accommodate compare arguments that start with "-". Besides, we do not worry about this when invoking diff or cmp; why start now with sed? Using "--" to separate options from argument would trigger sed failure in at least Solaris 7, HP-UX 11.00, IRIX 6.5, FreeBSD 6.4, OpenBSD 4.9 and NetBSD 5.1. Reported by Bruno Haible. 2012-01-02 Bruno Haible Enhance tests for module 'isatty'. * modules/isatty-tests (Depends-on): Add pipe-posix. * tests/test-isatty.c: Include . (DEV_NULL): New macro.

Suggested by Paolo Bonzini. 2012-01-02 Bruno Haible canonicalize: Tweak 2011-12-29 commit. * lib/canonicalize.c (canonicalize_filename_mode): Fix typo in comment. * lib/canonicalize.h (canonicalize_filename_mode): Update specification. 2012-01-02 Jim Meyering gitlog-to-changelog: describe input syntax in --help output * build-aux/gitlog-to-changelog (usage) [SPECIAL SYNTAX]: New section. gitlog-to-changelog: fix typo in --help: show backslash before email @ * build-aux/gitlog-to-changelog (usage): An "@" was backslash-escaped in sources, but not in actual output. 2011-12-30 Jim Meyering gitlog-to-changelog: don't malfunction when name contains %-directive * build-aux/gitlog-to-changelog (main): Don't let a %-directive in a name string cause trouble. E.g., with a user name of "%s", gitlog-to-changelog would fail with "Missing argument in sprintf at..." 2011-12-30 Gary V. Vaughan gitlog-to-changelog: Copyright-paperwork-exempt: yes == (tiny change) * build-aux/gitlog-to-changelog (main): Map the string, at beginning of line in a git commit log, "Copyright-paperwork-exempt: yes", to the " (tiny change)" notation that is appended to the standard ChangeLog "date name email" header line. 2012-01-01 Jim Meyering test-framework-sh: init.sh: fix "make dist" failure When using gnulib-tool's --with-tests option and any module that depends on test-framework-sh, "make dist" would fail due to the lack of init.sh *in lib/*. The EXTRA_DIST += init.sh is required in the gltests directory, and not in the gllib/ directory. One way to work around that is to move the EXTRA_DIST += init.sh from the primary module to the -tests one: * modules/test-framework-sh-tests (EXTRA_DIST): Add init.sh here, ... * modules/test-framework-sh (Makefile.am): ...not here. Reported by Tom G. Christensen in http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/29519 version-etc: update copyright year reported by --version * lib/version-etc.c (COPYRIGHT_YEAR): Update to 2012. 2011-12-31 Pádraig Brady canonicalize: only stat() if required * lib/canonicalize.c (canonicalize_filename_mode): Avoid calling l?stat() when both CAN_MISSING, and CAN_NOLINKS are set, as we neither need to resolve symlinks or test component existence. 2011-12-31 Paul Eggert doc: cover st_ino issues once; add OpenVMS etc. * doc/posix-functions/stat.texi (stat): * doc/posix-functions/lstat.texi (lstat): * doc/posix-functions/fstatat.texi (fstatat): * doc/posix-functions/fstat.texi (fstat): Move general 'struct stat' stuff to sys_stat.texi, leaving behind a pointer. * doc/posix-headers/sys_stat.texi (sys/stat.h): Merge duplicate info about 'struct stat' problems into here. Mention issues with OpenVMS, GNU/Linux NFS, NetApp, ClearCase, and suggest partial workarounds. same-inode: port to OpenVMS * lib/same-inode.h (SAME_INODE): Port to OpenVMS by checking all three st_ino values. 2011-12-30 Pádraig Brady canonicalize: fix references to stat() and lstat() * lib/canonicalize.c (canonicalize_filename_mode): Ensure references always resolve to a replacement function if required (even via a macro). 2011-12-30 Jim Meyering gitlog-to-changelog: remove a little duplication * build-aux/gitlog-to-changelog (main): Grep @lines once, rather than twice. 2011-12-29 Pádraig Brady canonicalize: add support for not resolving symlinks * lib/canonicalize.h: Add the CAN_NOLINKS flag to indicate we don't want to follow symlinks. Also provide CAN_MODE_MASK to aid setting these existing mutually exclusive values. * lib/canonicalize.c (canonicalize_filename_mode): Extract the flags from can_mode parameter, which are currently just used to select between stat() and lstat(). Also ensure that mutually exclusive values are flagged immediately as invalid. * tests/test-canonicalize.c: Verify symlinks are not followed, and that invalid flag combinations are diagnosed. 2011-12-25 Jim Meyering gitlog-to-changelog: do not clump multi-paragraph entries Identical header lines (date,name,email+coauthors) are suppressed, thus putting all entries with those same characteristics under a single header. However, when a log entry consists of two or more paragraphs, it may not be clear where it starts and ends. This change makes it so that such an entry is always separated from others by a header line, even when that header would otherwise be suppressed. * build-aux/gitlog-to-changelog: Implement the above. Inspired by a related request from Stefano Lattarini in http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/29456 2011-12-25 Paul Eggert announce-gen: fix `cmd' typo in diagnostic * build-aux/announce-gen (print_changelog_deltas): Fix typo in diagnostic: a missing '$' meant that the command was not output. 2011-12-23 Jim Meyering test-framework-sh: distribute init.sh * modules/test-framework-sh (EXTRA_DIST): Append init.sh. Otherwise, "make -C gnulib-tests check" (at least in grep) would fail due to the lack of init.sh. maint: remove explicit Files: tests/init.sh; depend on test-framework-sh * modules/atexit-tests: Rather than listing tests/init.sh, now that there's a module for it, simply depend on that new module. * modules/closein-tests: Likewise. * modules/exclude-tests: Likewise. * modules/getcwd-tests: Likewise. * modules/perror-tests: Likewise. * modules/pread-tests: Likewise. * modules/pwrite-tests: Likewise. * modules/vc-list-files-tests: Likewise. * modules/verify-tests: Likewise. * modules/xalloc-die-tests: Likewise. * modules/xstrtoimax-tests: Likewise. * modules/xstrtol-tests: Likewise. * modules/xstrtoll-tests: Likewise. * modules/xstrtoumax-tests: Likewise. * modules/yesno-tests: Likewise. 2011-12-22 Jim Meyering test-framework-sh: add minimal tests of init.sh's compare function * modules/test-framework-sh-tests: New file. * tests/test-init.sh: New file. test-framework-sh: new module * modules/test-framework-sh: New file. * MODULES.html.sh (Support for maintaining and releasing projects): List it. init.sh: do not emit simulated diff output to stderr * tests/init.sh (compare_dev_null_): Print to stdout, not stderr. 2011-12-22 Reuben Thomas .gitignore: ignore gnulib.dvi and regex.info * doc/.gitignore:add gnulib.dvi and regex.info 2011-12-22 Jim Meyering init.sh: correct previous change * tests/init.sh (compare): My previous change was wrong. Don't clobber "$?". Spotted by Stefano Lattarini and Pádraig Brady. init.sh: avoid unwarranted test failure when using "set -e" * tests/init.sh (compare): Ignore nonzero exit from compare_dev_null_. Otherwise, in a test script that uses "set -e" (like many in vc-dwim) a use like "compare exp out" would get evoke an unconditional failure. 2011-12-21 Alfred M. Szmidt bootstrap: fix it to honor $ACLOCAL_FLAGS once again The 2011-12-17 change, commit 767ccd40, replaced a manual invocation of aclocal that used explicit $ACLOCAL_FLAGS with an invocation of autoreconf that did not. * build-aux/bootstrap: Use $ACLOCAL_FLAGS when invoking autoreconf. Reported by Mats Erik Andersson . 2011-12-17 Jim Meyering bootstrap: remove some now-unneeded code This script arose back when gnulib-tool was young. Since then, it has seen improvements that render much of this script unnecessary. In particular, it can now make symlinks to the files it uses. Also, I no longer see as much value in marking files as read-only via comments. If you relied on the symlink-creation feature of the preceding version of this script, you can get most of that functionality by adding the --symlink option to the definition of gnulib_tool_option_extras in your bootstrap.conf file. * build-aux/bootstrap (AUTOPOINT, AUTORECONF): Factor out definitions. Run autopoint and libtoolize *before* gnulib-tool. After it, run an abbreviated autoreconf, rather than a loop around all tools. (slirp, bt_mark_as_generated): Remove functions. 2011-12-18 Paul Eggert ftoastr: fix typo * lib/ftoastr.h: Fix misspelling in comment. 2011-12-18 Reuben Thomas * top/README-release: fix punctuation. 2011-12-17 Jim Meyering bootstrap: correct the recent buildreq change The 2011-12-07 commit, 39f5f1e4, omitted some '*'s, and thus had no effect. * build-aux/bootstrap (buildreq): Bracket each search term with "*...*", so that the shell "case" statement works as intended. Add comments. 2011-12-17 Bernhard Voelker build: let bootstrap resort to wget when downloading .po files * build-aux/bootstrap (download_po_files): Fallback to wget when downloading the .po files via rsync fails. This is necessary to bootstrap from behind a strict firewall. 2011-12-15 Paul Eggert stdint: don't assume C++11 when compiling with g++ Problem reported for glibc 2.14 and g++ by Alexander V. Lukyanov in . * m4/stdint.m4 (gl_STDINT_H): Don't go to extra work to make it work also in C++ before C++11, as that improperly inhibits generating a substitute stdint.h for that case. 2011-12-15 Paul Eggert alloca: protect comment from gnulib-tool * lib/alloca.c: Change "GCC version 2" to "GCC 2" in comment, so that gnulib-tool doesn't think it's a license, and munge it to say "GCC version 3". 2011-12-15 Ludovic Courtès (tiny change) localcharset: Use an absolute path in TESTS_ENVIRONMENT. * modules/localcharset (LOCALCHARSET_TESTS_ENVIRONMENT): Use $(abs_top_builddir) instead of $(top_builddir). 2011-12-14 Alex Nelson (tiny change) strftime-tests: also test nanoseconds * tests/test-strftime.c (T): Add a test of %N. 2011-12-13 Paul Eggert inttypes, stdint: add C++11 support C++11 says there's no need to define __STDC_CONSTANT_MACROS etc. when including inttypes.h and stdint.h. Support this change to the standard. * doc/posix-headers/inttypes.texi (inttypes.h): * doc/posix-headers/stdint.texi (stdint.h): Document this. * lib/inttypes.in.h (__STDC_FORMAT_MACROS) [! __cplusplus]: Define if not defined already, for the benefit of pre-C++11 hosts. Define the standard format macros (e.g., PRId8) always. * lib/stdint.in.h (__STDC_CONSTANT_MACROS, __STDC_LIMIT_MACROS): Likewise, if __cpluspus. Define the standard constant and limit macros (e.g., INT8_C, INT8_MAX) always. * m4/inttypes.m4 (gl_INTTYPES_INCOMPLETE): Do not define GL_TRIGGER_STDC_LIMIT_MACROS or __STDC_LIMIT_MACROS; no longer needed. * m4/stdint.m4 (gl_STDINT_H): Update comments about these macros. * tests/test-inttypes.c (__STDC_LIMIT_MACROS, __STDC_CONSTANT_MACROS) (__STDC_FORMAT_MACROS): Do not define, since we assume C++11 API now. * tests/test-stdint.c (__STDC_LIMIT_MACROS, __STDC_CONSTANT_MACROS): Likewise. 2011-12-12 Paul Eggert nonblocking tests: Fix test failure on Linux/PPC. Suggested by Prerna Saxena in . * tests/test-nonblocking-pipe.h (PIPE_DATA_BLOCK_SIZE) [Linux/PPC64]: Set to 1100000. 2011-12-12 Jim Meyering argmatch: don't hard-code `' when listing valid option arguments * lib/argmatch.c (argmatch_valid): Don't hard-code `%s'. Instead, use the quote function to add quotes. Use fputs rather than fprintf for the format string with no format directive. 2011-12-07 Eric Blake bootstrap: detect tools required by gnulib-tool * build-aux/bootstrap (buildreq): Provide minimum implicit dependencies. * DEPENDENCIES: Mention patch as a prereq. 2011-12-04 Bruno Haible sethostname: Port to Windows platforms. * lib/sethostname.c: Provide an alternate implementation for Windows platforms. * tests/test-sethostname2.c (geteuid): Redefine on Cygwin. (main): Skip the test if sethostname() fails with EPERM.

A test program for the sethostname module. * tests/test-sethostname.c: Likewise. 2011-12-03 Bruno Haible Tweak last commit. * lib/unistd.in.h (sethostname): Keep declarations in alphabetic order. Fix preprocessor directives indentation. Fix typos. * m4/unistd_h.m4 (gl_UNISTD_H_DEFAULTS): Keep alphabetic order. * modules/unistd (Makefile): Likewise. 2011-12-01 Ben Walton Integrate the sethostname module into unistd. * lib/unistd.in.h: Integrate the SETHOSTNAME preprocessor handling into the unistd.h header. * m4/unistd_h.m4: Setup the autoconf handling for the SETHOSTNAME preprocessor directives. * modules/unistd: Setup the Makefile substitutions of the SETHOSTNAME preprocessor directives. 2011-12-03 Bruno Haible Tweak last commit. * lib/sethostname.c: Don't include .

Thus, errors in git logs tend to stay there forever. However, when we generate a ChangeLog file -- typically for distribution -- from that git log, we can actually make corrections in the generated file. The key lies in recording in machine-readable/applicable form the desired corrections. See --help for description and an example. * build-aux/gitlog-to-changelog (parse_amend_file): New function. (usage): Describe it; alphabetize option descriptions. (main): Honor the new option, carefully. 2011-11-01 Jim Meyering gitlog-to-changelog: avoid an infloop * build-aux/gitlog-to-changelog: Don't infloop for a commit log that ends up being empty. 2011-11-01 Paul Eggert * MODULES.html.sh: Fix sed-script shell quoting and locale issues. (func_module): Replace foo=` ... sed -e COMPLICATED ... ` with bar=COMPLICATED; foo=` ... sed -e "$bar" ... ` when COMPLICATED contains (possibly-quoted) backslashes. This should avoid all-too-common shell bugs if COMPLICATED contains backslashes in the "wrong" places. Reported by David Evans in . When 'sed' uses character ranges like A-Z, invoke it in the C locale, because we want ASCII ranges. Is there some reason we don't use the C locale everywhere in this script? (func_module, top level): Avoid unwanted pathname expansion when $repo_url_prefix or $repo_url_suffix_repl contain shell metacharacters like '?' and '*'. 2011-11-01 Bruno Haible fchownat: Improve description. * modules/fchownat (Description): Add link to function. 2011-11-01 Paul Eggert * tests/test-stdalign.c (TEST_ALIGNMENT): Shrink back to 8. mingw supports alignments only up to 8 (!).

Include macros.h, for ASSERT. (DECLARE_ALIGNED): Remove. (TEST_ALIGNMENT): Define to 16 if alignment is supported (more likely to catch bug), and to 1 if not (simplifies the rest of the code). (CHECK_STATIC): Always declare the alignment test vars; that's simpler. (CHECK_AUTO): Remove. (CHECK_ALIGNED): Check only the alignment of the static vars, since auto var alignment isn't supported by Sun C 5.11. (CHECK_TYPES): Remove. All uses replaced by inline code, so that ASSERT failures are easier to diagnose. 2011-10-31 Bruno Haible doc about some IRIX 5.3 problems. * doc/posix-functions/getpwnam_r.texi: Mention incompatible declaration on IRIX 5.3. * doc/posix-headers/poll.texi: Mention missing nfds_t on IRIX 5.3. * doc/posix-functions/ptsname.texi: Mention missing declaration on IRIX 5.3. * doc/posix-functions/grantpt.texi: Likewise. * doc/posix-functions/unlockpt.texi: Likewise. * doc/posix-functions/lgamma.texi: Likewise. * doc/posix-functions/nextafter.texi: Likewise. * doc/posix-functions/remainder.texi: Likewise. * doc/posix-functions/select.texi: Mention misplaced declaration on IRIX 5.3. Reported by Tom G. Christensen . 2011-10-31 Dmitry V. Levin gitlog-to-changelog: fix git-log invocation. git-log mishandles date strings before 1970-01-01 UTC, and there is no use to specify --since=1970-01-01 by default anyway. * build-aux/gitlog-to-changelog: By default, when no --since option was given, do not specify explicit --since option to git-log. 2011-10-30 Dmitry V. Levin gitlog-to-changelog: new option --append-dot. * build-aux/gitlog-to-changelog: New option --append-dot, makes the first non-blank line of each commit message terminated with a dot. 2011-10-30 Bruno Haible ffsl, ffsll: Avoid compilation error due to 'restrict'. * lib/ffsl.h: Include . Suggested by Tom G. Christensen . 2011-10-30 Jim Meyering GNUmakefile: reenable "make syntax-check" for most projects Since Friday's commit 05e2d798, "maint.mk: don't maintain a second build-aux variable", "syntax-check" would do nothing but succeed with the "No version control files detected..." diagnostic (unless you happened to override _build-aux via cfg.mk). * top/GNUmakefile (_autoreconf, _build-aux): Move default definitions to precede inclusion of maint.mk. Otherwise, these variables would be used undefined in any project that does not override the default. 2011-10-29 Dmitry V. Levin gitlog-to-changelog: treat a message with only blank lines as empty. * build-aux/gitlog-to-changelog: Move the code that removes leading and trailing blank lines before the code that issues a warning about an empty commit message. 2011-10-30 Jim Meyering test-parse-datetime.c: avoid new DST-related false positive test failure * tests/test-parse-datetime.c (gmt_offset): Determine the "gmt_offset" based on the time/date we'll convert, not the current time. Otherwise, the moment we cross a DST boundary like today's in Europe, (CEST to CET), that offset ends up being one hour off. 2011-10-27 Bruno Haible fstat: Tweak documentation. * modules/fstat (Description): More precise description. 2011-10-27 Bruno Haible Update documentation regarding 'largefile' module. * doc/posix-functions/fstat.texi: Tweak wording. * doc/posix-functions/opendir.texi: Mention that the module fixes the problems with huge directories and/or small ino_t types. * doc/posix-functions/readdir.texi: Likewise. * doc/posix-functions/rewinddir.texi: Likewise. 2011-10-28 Gary V. Vaughan maint.mk: don't maintain a second build-aux variable. * maint.mk (build_aux): Removed. The maintainer-makefile module depends on GNUmakefile, which already maintains a cfg.mk overridable $(_build-aux) for projects with a non-standard build-aux directory location, although without the $(srcdir) prefix. Use that variable consistently instead of introducing a second one. Adjust all call sites. 2011-10-27 Paul Eggert Add stdalign module and use it in other modules. This is based on a previous proposal by Bruno Haible . stdalign: new module * doc/posix-headers/stdalign.texi, lib/stdalign.in.h, m4/stdalign.m4: * modules/stdalign: New files. * MODULES.html.sh (c1x_core_properties): Add stdalign. * doc/gnulib.texi (Header File Substitutes): Add stdalign. stdalign-tests: new module * modules/stdalign-tests, tests/test-stdalign.c: New files. argp: use stdalign * lib/argp-parse.c: Include .

Do not include twice, in md4.c. (UNALIGNED_P): Simplify by using alignof. Use uintptr_t, not size_t, because we are accessing a pointer's bit-pattern, not a size. * modules/crypto/gc-md4 (Depends-on): Add stdalign. * modules/crypto/gc-md5, modules/crypto/gc-sha1, modules/crypto/md4: * modules/crypto/md5, modules/crypto/sha1, modules/crypto/sha256: * modules/crypto/sha512: Likewise. sys_socket: use stdalign, not alignof * lib/sys_socket.in.h: Include instead of . * modules/sys_socket (Depends-on): Depend on stdalign, not alignof. 2011-10-27 Bruno Haible raise test: Avoid a test failure on Linux/MIPS. * tests/test-raise.c (main): Try raising signal 199, not 99. Needed because 99 is a valid signal on Linux/MIPS. 2011-10-27 Bruno Haible nonblocking tests: Fix test failure on Linux/MIPS. * tests/test-nonblocking-pipe.h (PIPE_DATA_BLOCK_SIZE) [Linux/MIPS]: Set to 270000. 2011-10-27 Bruno Haible utimensat: Work around problem on Linux/hppa. * lib/utimensat.c (rpl_utimensat) [Linux/hppa]: Reject invalid tv_nsec values. * doc/posix-functions/utimensat.texi: Mention the problem on Linux/hppa. 2011-10-25 Jim Meyering maint.mk: fix a bug in sc_prohibit_stddef_without_use * top/maint.mk (sc_prohibit_stddef_without_use): Don't require / *\(/ after symbols like NULL, size_t, etc. Reported by Alfred M. Szmidt. maint.mk: exempt ENODATA from a syntax-check rule * top/maint.mk (gl_extract_significant_defines_): Also exempt ENODATA from the sc_prohibit_always-defined_macros syntax-check rule. Add a comment. See this for more details: http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/28739/focus=28795 2011-10-23 Jim Meyering fts: close parent dir FD before returning from post-traversal fts_read The problem: the fts-using "mkdir -p A/B; rm -rf A" would attempt to unlink A, even though an FD open on A remained. This is suboptimal (holding a file descriptor open longer than needed), but otherwise not a problem on Unix-like kernels. However, on Cygwin with certain Novell file systems, (see http://cygwin.com/ml/cygwin/2011-10/msg00365.html), that represents a real problem: it causes the removal of A to fail with e.g., "rm: cannot remove `A': Device or resource busy" fts visits each directory twice and keeps a cache (fts_fd_ring) of directory file descriptors. After completing the final, FTS_DP, visit of a directory, RESTORE_INITIAL_CWD intended to clear the FD cache, but then proceeded to add a new FD to it via the subsequent FCHDIR (which calls cwd_advance_fd and i_ring_push). Before, the final file descriptor would be closed only via fts_close's call to fd_ring_clear. Now, it is usually closed earlier, via the final FTS_DP-returning fts_read call. * lib/fts.c (restore_initial_cwd): New function, converted from the macro. Call fd_ring_clear *after* FCHDIR, not before it. Update callers. Reported by Franz Sirl via the above URL, with analysis by Eric Blake in http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/28739 2011-10-23 Gary V. Vaughan Bruno Haible Jim Meyering readme-release: improve safety of release prep instructions. * README-release: Don't git pull all branches when only master is needed for the release process. Run make maintainer-clean before changing trees and merging. Don't try to run ./configure right after git pull in case files that influence the bootstrap process have changed, move the ./configure step to after running ./bootstrap. Don't bootstrap "one last time"... it's the first time! 2011-10-22 Bruno Haible errno, strerror-override: Support for MSVC 10. * lib/errno.in.h (GNULIB_defined_ETXTBSY): Remove macro.

Fixes a coreutils/tests/cp/perm failure. 2011-09-03 Paul Eggert openat: test for fstatat (..., 0) bug Further testing with tar suggests that fstatat (..., 0) does not work in general, on AIX 7.1; see . So, give up entirely on AIX 7.1's fstatat, and fall back on our replacement fstatat (which is what older AIX releases were using anyway). * lib/fstatat.c (fstatat) [HAVE_FSTATAT]: Do not undef. The only use is now changed to orig_fstatat. This was probably the right thing to do anyway. (FSTATAT_AT_FDCWD_0_BROKEN): Remove; no longer used. (rpl_fstatat) [FSTATAT_ZERO_FLAG_BROKEN]: Remove.

Reported by John W. Eaton for Octave. 2011-09-02 Bruno Haible Find 'ar' program that fits with --host argument. * m4/gnulib-common.m4 (gl_PROG_AR_RANLIB): Use AC_CHECK_TOOL. 2011-09-02 Bruno Haible tests: init.sh: Support any non-GNU diff. * tests/init.sh (compare): If "diff -c" is supported but "diff -u" is not, use "diff -c". Useful on AIX 6.1, HP-UX 11.31, OSF/1 5.1, Solaris 8. 2011-09-02 Bruno Haible tests: init.sh: work also with any non-GNU diff that supports -u * tests/init.sh: Relax check for diff -u support. Rather than checking for GNU diff via --version, simply check for support for -u itself.

(orig_fstatat) [HAVE_FSTATAT]: New function. (rpl_fstatat): Go back to the old way of doing things, except call orig_fstatat instead of fstatat. * m4/openat.m4 (gl_FUNC_FSTATAT): Remove unnecessary check for openat. Remove unnecessary check whether fstatat fills in st_size etc. 2011-09-01 Bruno Haible sys_select: Avoid a syntax error regarding timespec_t on IRIX 6.5. * lib/sys_select.in.h [__sgi]: When included from , just include the system's header. 2011-08-31 Jim Meyering tests: avoid spurious assertion failure in test-float.c on ppc64 * tests/test-float.c (test_long_double): Comment out an assertion, LDBL_MIN_EXP <= DBL_MIN_EXP, that is failing at least on PowerPC-64 with gcc-4.4.4. maint: indent with spaces, not TABs I need to get in the habit of running gnulib's "make check". Both of these would have been caught. * m4/largefile.m4: Indent with spaces, not TABs. * lib/parse-datetime.y (iso_8601_time): Likewise. Spotted by Pádraig Brady. test-parse-datetime.c: accommodate a relatively strict gcc warning * tests/test-parse-datetime.c (gmt_offset): Declare function "static", to avoid a warning from gcc's -Werror=missing-declarations. Insert a few spaces-before-funcall-parenthesis. 2011-08-17 J.T. Conklin parse-datetime: accept ISO 8601 date and time rep with "T" separator The parser now accepts ISO 8601 date-time strings with "T" as the separator. It has long parsed dates like "2004-02-29 16:21:42" with a space between the date and time strings. Now it also parses "2004-02-29T16:21:42" and fractional-second and time-zone-annotated variants like "2004-02-29T16:21:42.333-07:00" * lib/parse-datetime.y: Parse ISO 8601 extended date and time of day representation using the 'T' separator character. * doc/parse-datetime.texi (General date syntax): replace use of deprecated --iso-8601 option with --rfc-3339 in example of date command output formats that can be parsed. * tests/test-parse-datetime.c (tm_diff): New function, taken from lib/parse-datetime.y. (gmt_offset): New function. (main): Add additional test cases to validate ISO8601 extended date and time of day parsing. 2011-08-31 Bruno Haible freopen: Documentation. * doc/posix-functions/freopen.texi: Document the bug with the NULL file name. Reported by Claudio Bley . 2011-08-31 Claudio Bley (tiny change) freopen: Don't crash if the filename argument is NULL. * lib/freopen.c (rpl_freopen): Don't compare the filename if it is NULL. 2011-08-30 Paul Eggert openat: work around AIX 7.1 fstatat bug Problem reported by Kevin Brott for GNU tar, in the thread containing . * lib/fstatat.c (rpl_fstatat): Do not invoke underlying fstatat if FSTATAT_ST_SIZE_ETC_BROKEN. (fstatat) [FSTATAT_ST_SIZE_ETC_BROKEN && HAVE_FSTATAT]: #define to rpl_fstatat. * m4/openat.m4 (gl_FUNC_FSTATAT): New macro, with the fstatat-relevant part of gl_FUNC_OPENAT. Also, check for the AIX 7.1 bug, and use AC_CHECK_FUNCS_ONCE for fstatat. (gl_FUNC_OPENAT): Use it. Use AC_CHECK_FUNCS_ONCE for fchmodat, mkdirat, openat and unlinkat. 2011-08-30 Bruno Haible Avoid endless recursions if config.h includes some header files. * lib/fopen.c (__need_FILE): Define already before including config.h. * lib/freopen.c (__need_FILE): Likewise. * lib/open.c (__need_system_fcntl_h): Likewise. * lib/stat.c (__need_system_sys_stat_h): Likewise. * lib/lstat.c (__need_system_sys_stat_h): Likewise. Reported by Michael Goffioul . 2011-08-25 Karl Berry * config/srclist.txt (ylwrap): new try. * build-aux/ylwrap: new file. 2011-08-23 Bruno Haible tmpdir: Use a good default directory on native Windows. * lib/tmpdir.c: Include , pathmax.h. (P_tmpdir): Default to _P_tmpdir on native Windows. (path_search): On native Windows, try the value returned by GetTempPath before trying P_tmpdir. * modules/tmpdir (Depends-on): Add pathmax. Suggested by John Darrington . 2011-08-20 Reuben Thomas doc: fix typo in README-release * top/README-release: Capitalize first word of a sentence. 2011-08-19 Jim Meyering fts: do not exhaust memory when processing million-entry directories Before this change, traversing (via rm -rf, find, du, etc.) an N-entry directory would require about 256*N bytes of memory. Thus, it was easy to construct a directory too large to be processed by any of those tools. With this change, fts' maximum memory utilization is now limited to around 30MB. * lib/fts.c (FTS_MAX_READDIR_ENTRIES): Define. (fts_read): When we've processed the final entry (i.e., when ->fts_link is NULL) and fts_dirp is non-NULL, call fts_build using the parent entry to read any remaining entries. Dispatch depending on what fts_build returns: - NULL+stop, aka failure: stop - NULL otherwise: move up in the dir hierarchy - non-NULL: handle this new entry (fts_build): Declare and use new local, continue_readdir. Prepare to be called from fts_read, when the entries from a partially-read directory have just been exhausted. In that case, we'll skip the opendir and instead use the parent's fts_dirp and derive dir_fd from that. Finally, in the readdir loop, if we read max_entries entries, exit the loop ensuring *not* to call closedir. This is required so that fts_dirp can be reused on a subsequent call. Prompted by Ben England's report of memory exhaustion in find and rm -rf vs. NFS: https://bugzilla.redhat.com/719749. maint: fts: move decl of `dp' down into while loop; split a long line * lib/fts.c (fts_build): No semantic change. fts: add/use new struct member, fts_dirp We are about to use this to manage any directory with too many entries to read all of them into memory at once. To do that, we'll need to save the DIR* pointer in each affected FTSENT struct. * lib/fts_.h: Include . (struct FTSENT) [fts_dirp]: New member. * lib/fts.c (closedir_and_clear): Define. Use it in place of closedir so that we are sure to clear the new fts_dirp member when done with it. (fts_alloc): Initialize the new member. (fts_lfree): Free, if needed. maint: fts: give __opendir2 a new parameter and rename * lib/fts.c (__opendir2): Give it a new parameter, Pdir_fd, rather than surreptitiously using sole caller's "dir_fd". (fts_opendir): Rename from __opendir2. maint: fts.c: remove __opendir2's now-unused parameter, oflag * lib/fts.c (__opendir2): Remove unused parameter, oflag. maint: fts.c: correct off-by-one indentation * lib/fts.c (fts_build): Correct indentation, change style of a couple of block comments, and bracing style. maint: fts.c: move __opendir2 #define "up" out of function body * lib/fts.c (__opendir2): Move "up". No semantic change. maint: fts.c: remove #if-0'd FTS_WHITEOUT code * lib/fts.c: Remove #if-0'd FTS_WHITEOUT code. It's been #if-0'd out for a long time and besides was useful only on BSD systems. 2011-08-18 Paul Eggert regex: port to Stratus OpenVOS * lib/regex_internal.h (internal_function) [!_LIBC]: Simply define to empty, rather than attempting nonportable optimizations. Problem reported by Paul Green in: http://lists.gnu.org/r/bug-diffutils/2011-08/msg00047.html and fix suggested by Eric Blake in: http://lists.gnu.org/r/bug-gnulib/2011-08/msg00143.html 2011-08-17 Eric Blake getcwd: fix test failures on mingw * lib/getcwd.c (__getcwd): Early exit for ERANGE. * tests/test-getcwd.c (test_abort_bug, test_long_name): Don't fail test if long directory cannot be created, and allow mingw errno. getcwd-lgpl: fix m4 to match relaxed test for BSD * m4/getcwd.m4 (gl_FUNC_GETCWD_NULL): Relax probe. (gl_FUNC_GETCWD_SIGNATURE): New macro. (gl_FUNC_GETCWD_LGPL, gl_FUNC_GETCWD): Use it. * doc/posix-functions/getcwd.texi (getcwd): Tweak mentions of signature problem. getcwd: fix compilation on mingw64 * lib/unistd.in.h (includes) [mingw]: Include for getcwd. Reported by Marc-André Lureau. pipe2: silence compiler warning * lib/pipe2.c (pipe2): Hide label if it is not used. 2011-08-15 Ben Pfaff relocatable-prog: fix link error * modules/relocatable-prog (configure.ac) [RELOCATABLE]: Also invoke AC_LIBOBJ([relocatable]). This invocation was previously in the gl_RELOCATABLE_LIBRARY macro. That invocation was moved into modules/relocatable-lib without noticing that modules/relocatable-prog also invokes gl_RELOCATABLE_LIBRARY and also needs to build relocatable.c. 2011-08-12 Paul Eggert getaddrinfo: fix sh typo in gai_strerrorA decl checking * m4/getaddrinfo.m4 (gl_GETADDRINFO): Fix typo in the generated shell code: it contained a 'break' that was not in a loop. Apparently the macro assumed that AC_CHECK_DECLS is implemenented via a shell-language loop; this may have been true in old Autoconf versions, but it's not true in Autoconf 2.68. I found this bug when testing coreutils git on Solaris 8, whose shell complains about the syntax error. 2011-08-12 Simon Josefsson * lib/base64.c: Fix comment to reference RFC 4648. Suggested by Bruno Haible and Gijs van Tulder . 2011-08-11 Paul Eggert * build-aux/bootstrap (slurp): Remove obsolescent gettext.m4 patch. po/Makefile.in.in: fix make -q problem * build-aux/po/Makefile.in.in (check-macro-version): Remove this rule, since there's no file named 'check-macro-version' and its use as a file breaks make -q. (all): Don't depend on check-macro-version. (CHECK_MACRO_VERSION): New macro. (stamp-po): Use it. configmake: fix make -q problem * modules/configmake (configmake.h): Update configmake.h's time stamp even if the file does not change. Otherwise, 'make -q' fails. Problem reported by Simon Josefsson in . 2011-08-11 Jim Meyering git-version-gen: correct the advice in a comment * build-aux/git-version-gen: Correct comment.

Reported by Eric Blake. 2011-08-02 Jim Meyering maint.mk: relax the default _gl_TS_function_match regexp * top/maint.mk (_gl_TS_function_match): Don't require at least one space between function name and "(" in an "extern" declaration. That would fail to match a decl with no space there: extern void foo(); 2011-07-31 Iain Nicol git-version-gen: document that EXTRA_DIST must include .version * build-aux/git-version-gen: In the how-to-use comment, document that EXTRA_DIST must include .version. Otherwise, "make distcheck" will fail when run from an unpacked distribution tarball. 2011-08-01 Bruno Haible wctype-h: Fix last change. * m4/wctype_h.m4 (gl_WCTYPE_H): If towlower is defined, set REPLACE_TOWLOWER to 0.

There are 3 ways to customize it: - disable the test on a per file basis, as usual with rules using $(VC_LIST_EXCEPT) - replace the default doubled-word-selecting regexp (affects all files) - ignore a particular file-vs-doubled-word match I nearly used that last one to ignore the "is is" match in coreutils' NEWS file, since the text was "ls -is is ..." To do that, I would have added this line to cfg.mk: ignore_doubled_word_match_RE_ = ^NEWS:[0-9]+:is[ ]is$ but it would have ignored any "is is" match in NEWS. Low probability, but still...

Reported by Simon Josefsson. 2011-03-21 Jim Meyering strftime: fix a bug in yesterday's change * lib/strftime.c (add): Accommodate width's initial value of -1. Otherwise, nstrftime would copy uninitialized data into the result buffer. 2011-03-21 Jim Meyering tests: add strftime-tests module * tests/test-strftime.c: New file. * modules/strftime-tests: New module. 2011-03-20 Paul Eggert strftime: don't assume a byte count fits in 'int' * lib/strftime.c (add): Don't assume first arg fits in 'int'. I found this problem by static analysis, using gcc -Wstrict-overflow (GCC 4.5.2, x86-64). This reported an optimization that depended on an integer overflow having undefined behavior, but it turns out that the argument is a size, which might not fit in 'int' anyway, 2011-03-20 Paul Eggert stdio: don't require ignore_value around fwrite This patch works around libc bug 11959 . Without this patch, applications must often write ignore_value (fwrite (...)) even though the ignore_value is not helpful here. It's common to write many objects, using fwrite/printf/etc., and then use ferror to detect output error. I considered making this patch optional, but decided against it, because libc is obviously being inconsistent here: there is no reason libc should insist that user code must inspect fwrite return's value without also insisting that it inspect printf's, putchar's, etc. If user code wants to have a strict style where all these functions' values are checked (so that ferror need not be checked), we could add support for that style in a new gnulib module, but in the meantime it's better to be consistent and to support common usage. * lib/stdio.in.h (rpl_fwrite): Define this wrapper around fwrite, to work around libc bug 11959, if __USE_FORTIFY_LEVEL indicates that we are compiling in checking mode, and if not C++, and if not already wrapping fwrite for some other reason. (fwrite): #define to rpl_fwrite if the latter is defined. 2011-03-20 Bruno Haible verror: Fix compilation error introduced on 2011-02-13. * lib/verror.h (verror, verror_at_line): Use _GL_ATTRIBUTE_FORMAT macro instead of __attribute__. Reported by Tom G. Christensen . 2011-03-20 Paul Eggert Bruno Haible socklen: do not depend on sys_socket While trying to modify Emacs to use gnulib's socklen module, I discovered a circular dependency: socklen depends on sys_socket and vice versa. Emacs can use socklen, but it does not need sys_socket because it has its own substitute for sys/socket.h. * m4/socklen.m4 (gl_SOCKET_HEADERS): New macro, extracted from gl_TYPE_SOCKLEN_T. (gl_CHECK_SOCKET_HEADERS): New macro, taken from parts of gl_PREREQ_SYS_H_SOCKET.

Suggested by Eric Blake. 2011-02-25 Paul Eggert dirname: move m4/dos.m4 functionality into lib/dosname.h m4/dos.m4 needs to go. It laboriously invokes the C compiler, and extracts symbols from it, puts them into config.h; but it's much easier to use the symbols directly. filename.h already does this, but it disagrees with dos.m4 in some respects. This patch introduces a different include file dosname.h that packages up dos.m4, and then later we can work on merging filename.h and dosname.h. Applications that need only the easy-to-configure symbols should consider including dosname.h rather than dirname.h. * NEWS: Mention incompatible changes. * m4/dos.m4: Remove. * lib/dosname.h, modules/dosname: New files. * lib/dirname.h (ISSLASH, FILE_SYSTEM_PREFIX_LEN): (FILE_SYSTEM_DRIVE_PREFIX_CAN_BE_RELATIVE): (IS_ABSOLUTE_FILE_NAME, IS_RELATIVE_FILE_NAME): Move to lib/dosname.h. * lib/at-func.c, lib/at-func2.c, lib/openat.c, lib/savewd.c: Include dosname.h, not dirname.h. * lib/rmdir.c, lib/stat.c, lib/unlink.c, lib/unlinkat.c: Include dosname.h, for definitions of symbols like ISSLASH that used to be in config.h. * m4/dirname.m4 (gl_DIRNAME_LGPL): Do not require gl_AC_DOS. * m4/rmdir.m4 (gl_FUNC_RMDIR): Likewise. * m4/stat.m4 (gl_FUNC_STAT): Likewise. * m4/unlink.m4 (gl_FUNC_UNLINK): Likewise. * modules/dirname-lgpl (Files): Omit m4/dos.m4. * modules/rmdir (Files): Likewise. * modules/stat (Files): Likewise. * modules/unlink (Files): Likewise. * modules/dirname-lgpl (Depends-on): Add dosname. * modules/lstat (Depends-on): Likewise. * modules/openat (Depends-on): Likewise. * modules/rmdir (Depends-on): Likewise. * modules/savewd (Depends-on): Likewise. * modules/stat (Depends-on): Likewise. * modules/unlink (Depends-on): Likewise. * modules/openat (Depends-on): Remove dirname-lgpl. * modules/savewd (Depends-on): Likewise. * tests/test-dirname.c: Do not use removed symbols like FILE_SYSTEM_BACKSLASH_IS_FILE_NAME_SEPARATOR.

In either case, we know the answer without further tests. Do not compile _AC_TYPE_LONG_LONG_SNIPPET twice. Instead, compile it at most once, and use its results for both long long int and unsigned long long int. This is more likely to be efficient in the common case where the program wants to check for both long long int and unsigned long long int.

Emacs worked fine on RHEL 5.5, but it crashed due to memory corruption on Solaris 10 with Sun C 5.11. Emacs normally ORs 3-bit tags into their low-order bits that are otherwise zero. This tagging is optional inside Emacs but is preferred and is used when __attribute__ ((__aligned (8))) works, as it does with both recent-enough GCC and with Sun C 5.11. However, Sun C 5.11 is not GCC and does not #define __GNUC__ and __GNUC_MINOR__. When I added the getloadavg module to Emacs, it brought in stdlib.in.h, which contained this fragment: #ifndef __attribute__ # if __GNUC__ < 2 || (__GNUC__ == 2 && __GNUC_MINOR__ < 8) # define __attribute__(Spec) /* empty */ # endif #endif When files that include were compiled with Sun C 5.11, the above code disabled __attribute__ ((__aligned (8))), which caused variables to not be properly aligned, which eventually led to the pointer corruption mentioned above. (This was a bit hard to diagnose, unfortunately.) Several "#define __attribute__(X) /* empty */" code snippets need to be eradicated from Gnulib to work with non-GCC compilers that support __attribute__. The Autoconf way to do this is to test for each kind of attribute that we want support for, and selectively enable that in source code. Fix this problem just for stdlib.h, by adding a test for the __noreturn__ attribute, and change stdlib.in.h to use that test when needed. This technique can be easily generalized to the other *.in.h files and attributes, and a similar technique can be used for *.h and *.c files. This patch is enough to solve the problem for Emacs + getloadavg, and I thought I'd publish it for feedback before undertaking further, similar fixes in other modules. This patch does not arrange to #define HAVE_ATTRIBUTE_NORETURN because it's not needed for stdlib.h. It merely substitutes the value directly into stdlib.h. We may well need to #define it, or similar symbols, for other modules, but it's nice to also have an option to not #define it for applications like Emacs that do not need it. * lib/stdlib.in.h (__attribute__): Do not #define.

It was motivated by Emacs, which uses gnulib but does not need HAVE_STDBOOL_H. 2011-02-04 Bruno Haible wcsnrtombs: Prepare for new module wwcsnrtombs. * lib/wcsnrtombs-impl.h: New file, extracted from lib/wcsnrtombs.c. * lib/wcsnrtombs.c: Include it. * modules/wcsnrtombs (Files): Add lib/wcsnrtombs-impl.h. wcsrtombs: Prepare for new module wwcsrtombs. * lib/wcsrtombs-impl.h: New file, extracted from lib/wcsrtombs.c. * lib/wcsrtombs.c: Include it. * modules/wcsrtombs (Files): Add lib/wcsrtombs-impl.h. mbsnrtowcs: Prepare for new module mbsnrtowwcs. * lib/mbsnrtowcs-impl.h: New file, extracted from lib/mbsnrtowcs.c. * lib/mbsnrtowcs.c: Include it. * modules/mbsnrtowcs (Files): Add lib/mbsnrtowcs-impl.h. mbsrtowcs: Prepare for new module mbsrtowwcs. * lib/mbsrtowcs-impl.h: New file, extracted from lib/mbsrtowcs.c. * lib/mbsrtowcs.c: Include it. * modules/mbsrtowcs (Files): Add lib/mbsrtowcs-impl.h. 2011-02-04 Bruno Haible vasnprintf: Reduce use of malloc for small format strings. * lib/printf-args.h (N_DIRECT_ALLOC_ARGUMENTS): New macro. (arguments): Add room for the first 7 arguments. * lib/printf-parse.h (N_DIRECT_ALLOC_DIRECTIVES): New macro.

See . 2011-01-30 Simon Josefsson ignore-value: Fix self-test. * tests/test-ignore-value.c: Include sys/types.h for off_t. 2011-01-29 Paul Eggert TYPE_MAXIMUM: avoid theoretically undefined behavior * lib/intprops.h (TYPE_MINIMUM, TYPE_MAXIMUM): Do not shift a negative number, which the C Standard says has undefined behavior. In practice this is not a problem, but might as well do it by the book. Reported by Rich Felker and Eric Blake; see . * lib/strtol.c (TYPE_MINIMUM, TYPE_MAXIMUM): Likewise. * m4/mktime.m4 (AC_FUNC_MKTIME): Likewise. * m4/nanosleep.m4 (gl_FUNC_NANOSLEEP): Likewise. * m4/parse-datetime.m4 (gl_PARSE_DATETIME): Likewise. * m4/stdint.m4 (gl_STDINT_H): Likewise. * lib/mktime.c (TYPE_MAXIMUM): Redo slightly to match the others. mktime: #undef mktime before #defining it * lib/mktime.c (mktime) [DEBUG]: #undef mktime before #defining it. mktime: systematically normalize tm_isdst comparisons * lib/mktime.c (isdst_differ): New function. (__mktime_internal): Use it systematically for all isdst comparisons. This completes the fix for libc BZ #6723, and removes the need for normalizing tm_isdst. See (not_equal_tm) [DEBUG]: Use isdst_differ here, too. mktime: fix some integer overflow issues and sidestep the rest This was prompted by a bug report by Benjamin Lindner for MinGW . His bug is due to signed integer overflow (0 - INT_MIN), and I I scanned through mktime.c looking for other integer overflow problems, fixing all the bugs I found. Although the C Standard says the resulting code is still not safe in the presence of integer overflow, in practice it should be good enough for all real-world two's-complement implementations, except for debugging environments that deliberately trap on integer overflow (e.g., gcc -ftrapv). * lib/mktime.c (WRAPV): New macro. (SHR): Also check that long_int and time_t shift right in the usual way, before using the fast-but-unportable method. (TYPE_ONES_COMPLEMENT, TYPE_SIGNED_MAGNITUDE): Remove, no longer used. The code already assumed two's complement, so there's no need to test for alternatives. All uses removed. (TYPE_MAXIMUM): Don't rely here on overflow behavior not defined by the C standard. Problem reported by Rich Felker in . (twos_complement_arithmetic): Also check long_int and time_t. (time_t_avg, time_t_add_ok, time_t_int_add_ok): New functions. (guess_time_tm, ranged_convert, __mktime_internal): Use them. (__mktime_internal): Avoid integer overflow with unary subtraction in two instances where -1 - X is an adequate replacement for -X, since the calculations are approximate. 2011-01-29 Eric Blake mktime: avoid infinite loop * m4/mktime.m4 (AC_FUNC_MKTIME): Avoid overflow on possibly-signed type; behavior is still undefined but portable to all known targets. Reported by Rich Felker. 2011-01-29 Simon Josefsson rename, unlink, same-inode: Relicense. * modules/rename (License): Relax from LGPLv3+ to LGPLv2+. * modules/unlink (License): Likewise. * modules/same-inode (License): Likewise. 2011-01-28 Paul Eggert mktime: avoid problems on NetBSD 5 / i386 * lib/mktime.c (long_int): New type. This works around a problem on NetBSD 5 / i386, where 'long int' and 'int' are both 32 bits but time_t is 64 bits, and where I expect the existing code is wrong in some cases. (leapyear, ydhms_diff, guess_time_tm, __mktime_internal): Use it. (ydhms_diff): Bring back the compile-time check for wide-enough year and yday. mktime: fix misspelling in comment * lib/mktime.c (__mktime_internal): Fix misspelling in comment.

Reported by Scott McCreary. 2011-01-18 Paul Eggert include_next: do not check for standard headers like stddef.h I found this problem when modifying Emacs to use gnulib. I noticed that it added HAVE_STDDEF_H to config.h, even though gnulib always assumes exists as per README and this symbol is unnecessary. * m4/include_next.m4 (gl_NEXT_HEADERS): New macro, which does not use AC_CHECK_HEADERS_ONCE, but which otherwise contains what gl_CHECK_NEXT_HEADERS used to contain. This makes 'configure' run faster for headers like stddef.h that are known to exist.

MULTIBYTE_IS_FORMAT_SAFE, and that is true only if __osf__ is defined, and I suspect OSF doesn't need these other modules. If my guess is wrong, we'll need to come up with a variant of strftime that doesn't need the multibyte modules. I discovered this problem when attempting modify Emacs to use the strftime module. With the previous gnulib, this caused Emacs to need 31 new files, ranging from lib/config.charset to m4/wint_t.m4. This was overkill and I expect would be offputting to the Emacs maintainers. After this change, only 6 new files are needed, namely strftime.[ch], srtftime.m4, stdbool.in.h, stdbool.m4, and tm_gmtoff.m4. * lib/strftime.c (MULTIBYTE_IS_FORMAT_SAFE): Define to 1 always. Suggested by Bruno Haible in . * m4/strftime.m4 (gl_FUNC_STRFTIME): Do not require AC_TYPE_MBSTATE_T, and do not check for wchar.h. * modules/strftime (Files): Remove m4/mbstate_t.m4.

This avoids a compilation failure in projects that use save-cwd without also using the xgetcwd module. 2011-01-11 Paul Eggert ftoastr: split into 3 modules ftoastr, dtoastr, ldtoastr This is so that a program like Emacs, which needs only dtoastr, does not have to bother with distributing and compiling ftoastr and ldtoastr. * MODULES.html.sh: Document these modules (ftoastr wasn't documented). * modules/dtoastr, modules/ldtoastr: New files. * modules/ftoastr: Now works just for 'float'. (Files): Remove lib/dtoastr.c, lib/ldtoastr.c. (Makefile.am): Remove ftoastr.h (not needed and no effect), dtoastr.c, ldtoastr.c. 2011-01-11 Jim Meyering save-cwd: remove #if-!HAVE_FCHDIR'd code; use the fchdir module There is no need to work around the lack of the fchdir function, since gnulib can now provide a replacement when required. * lib/save-cwd.c: Remove #if !HAVE_FCHDIR...#endif code. * modules/save-cwd (Depends-on): Add fchdir. 2011-01-11 Paul Eggert openat, save-cwd: avoid xmalloc This removes a direct (but undocumented) dependency of openat on xalloc, along with an indirect dependency via save-cwd. It also removes a dependency of save-cwd on xgetcwd, and thereby indirectly on xalloc. This change causes the openat substitute to fall back on save_cwd when memory is tight, and for save_cwd to fail instead of dying when memory is tight, but that's good enough. Problem and initial idea for fix reported by Bastien Roucaries in . * lib/openat-proc.c: Include stdlib.h (for malloc), not xalloc.h (for xmalloc). (openat_proc_name): Use malloc, not xmalloc. * lib/save-cwd.c (save_cwd): Use getcwd, not xgetcwd. * modules/save-cwd (Files): Depend on getcwd, not xgetcwd. openat: Increase OPENAT_BUFFER_SIZE from 512 to at least 1024 This avoids heap allocation for file names whose lengths are in the range 512..1023, with the upper bound increasing to at most 4031 depending on the platform's PATH_MAX. (We do not want pathmax.h here as it might supply a non-constant PATH_MAX.) * lib/openat-priv.h (SAFER_ALLOCA_MAX, SAFER_ALLOCA): New macros. Perhaps they should be moved to malloca.h? (OPENAT_BUFFER_SIZE): Use them. 2011-01-10 Bruno Haible doc: Update users.txt. * users.txt: Add recutils. 2011-01-09 Karl Berry * doc/posix-functions/gai_strerror.texi: Insert missing @item. * doc/configmake.texi: New file. * doc/gnulib.texi: Include it. * modules/configmake: Move documentation from here. 2011-01-09 Bruno Haible Update to Unicode 6.0.0. * lib/gen-uni-tables.c (symbolic_width): Fix bounds of planes. (get_lbp): Update for Unicode 6.0.0. * lib/uniwidth/width.c (nonspacing_table_data): Add U+065F, U+0859..U+085B, U+093A, U+0956..U+0957, U+0F8D..U+0F8F, U+135D..U+135E, U+1BE6, U+1BE8..U+1BE9, U+1BED, U+1BEF..U+1BF1, U+1DFC, U+2D7F, U+11001, U+11038..U+11046.

Less syntax is better, too. 2011-01-03 Jim Meyering git-version-gen: convert leading TABs to spaces * build-aux/git-version-gen: Expand leading TABs. git-version-gen: handle failed "git rev-list" * build-aux/git-version-gen: Rather than leaking a "fatal" error from git and proceeding as if it had succeeded but printed no SHA1 checksums, suppress the diagnostic and handle the failure. Reported by Bruce Korb in http://marc.info/?l=git&m=129399145930450&w=2 git-version-gen: include command name in one more diagnostic * build-aux/git-version-gen: When the required .tarball-version file was missing or unreadable, you might see the diagnostic from "cat", but no trace of the name of the invoking script.

On Solaris 8, it fails with errno == ENOSYS, because there is no futimens (so it can't use the fd), and there is no lutimens (so it can't implement AT_SYMLINK_NOFOLLOW on symlinks). vsnprintf: make more consistent with snprintf; doc fixes * doc/posix-functions/snprintf.texi (snprintf): The workaround for the byte count return problem was promoted from the snprintf-posix to the snprintf module. * doc/posix-functions/vsnprintf.texi (vsnprintf): Likewise. * m4/vsnprintf.m4 (gl_FUNC_VSNPRINTF): Also check gl_SNPRINTF_RETVAL_C99, for consistency with gl_FUNC_SNPRINTF. * tests/test-snprintf.c (main): Check the byte count returned. * tests/test-vsnprintf.c (main): Likewise. 2010-12-23 Eric Blake sigpipe: relax to LGPLv2+, since it did not have any LGPLv3+ parts * modules/sigpipe (License): Relax license. 2010-12-22 Paul Eggert doc: document Solaris printf bug with large float precisions * doc/posix-functions/dprintf.texi (dprintf): * doc/posix-functions/fprintf.texi (fprintf): * doc/posix-functions/printf.texi (printf): * doc/posix-functions/snprintf.texi (snprintf): * doc/posix-functions/sprintf.texi (sprintf): * doc/posix-functions/vdprintf.texi (vdprintf): * doc/posix-functions/vfprintf.texi (vfprintf): * doc/posix-functions/vprintf.texi (vprintf): * doc/posix-functions/vsnprintf.texi (vsnprintf): * doc/posix-functions/vsprintf.texi (vsprintf): Mention that these functions mishandle large floating point precisions on Solaris 10. The same bug is also present in Solaris 8, and I assume earlier. This causes "cd gnulib-tests; make check" to fail on Solaris 8 (and I assume, later) when building the latest coreutils, in test-vasprintf-posix's call to my_asprintf (&result, "%.4000f %d", 1.0, 99). I have not checked the wide flavors (e.g., wprintf) so this patch just updates the documentation for the narrow ones. test-posixtm.c: add two tests * tests/test-posixtm.c: Add two tests, to highlight the bug in Solaris 10 (and earlier) localtime.

The most noticeable effect was failure of any application making nontrivial use of fts: rm, du, chown, chmod etc. E.g., "mkdir -p a/b; ./rm -rf a" would fail with ./rm: traversal failed: `a': Bad file descriptor Debugging that, you see that even though FD 6 was closed just prior to the opendir call in fd_clone_opendir, its resulting dir->dd_fd was 8, rather than the expected value of 6: Breakpoint 3, fdopendir_with_dup (fd=6, older_dupfd=-1) at fdopendir.c:93 93 close (fd); (gdb) n 94 dir = fd_clone_opendir (dupfd); (gdb) n 95 saved_errno = errno; (gdb) p dir->dd_fd $11 = 8 Notice how it closes FD 6, then gets a DIR* pointer using FD 8. The problem is that on OpenBSD, fd_clone_opendir has to resort to using the old-style save/restore CWD mechanism, due to its lack of openat/proc support, and *that* would steal the FD (6) that opendir was supposed to use. The fix is to squirrel away the desired FD so that save_cwd uses a different one, and then free the dest FD right before calling opendir. That guarantees opendir will use the required file descriptor. * lib/fdopendir.c (fd_clone_opendir): Handle the above. 2010-10-08 Bruno Haible sys_select: Avoid warning due to undeclared memset() on OpenBSD 4.5. * lib/sys_select.in.h: Include also on OpenBSD. 2010-10-08 Bruno Haible nanosleep: Make replacement POSIX compliant. * lib/nanosleep.c (nanosleep): Return -1/EINVAL if the delay's tv_nsec is out of range. Reported by Jim Meyering. 2010-10-08 Paul Eggert bootstrap: add hook for altering gnulib.mk, for Bison * build-aux/bootstrap (gnulib_mk_hook): New function, so that the Bison bootstrapping process can rewrite file names and variables in this file before later parts of 'bootstrap' use the file. Bison wants to include lib/gnulib.mk from the top-level makefile, so it needs the file names in this file to be relative to the top level, not relative to lib; plus it needs variable names to be rewritten. (slurp): Use the new function. bootstrap: reformat for readability * build-aux/bootstrap: Rewrite to avoid lines longer than 80 columns. 2010-10-08 Eric Blake docs: update cygwin progress * doc/posix-functions/cacos.texi (cacos): Added after cygwin 1.7.7. * doc/posix-functions/cacosf.texi (cacosf): Likewise. * doc/posix-functions/cacosh.texi (cacosh): Likewise. * doc/posix-functions/cacoshf.texi (cacoshf): Likewise. * doc/posix-functions/carg.texi (carg): Likewise. * doc/posix-functions/cargf.texi (cargf): Likewise. * doc/posix-functions/casin.texi (casin): Likewise. * doc/posix-functions/casinf.texi (casinf): Likewise. * doc/posix-functions/casinh.texi (casinh): Likewise. * doc/posix-functions/casinhf.texi (casinhf): Likewise. * doc/posix-functions/catan.texi (catan): Likewise. * doc/posix-functions/catanf.texi (catanf): Likewise. * doc/posix-functions/catanh.texi (catanh): Likewise. * doc/posix-functions/catanhf.texi (catanhf): Likewise. * doc/posix-functions/ccos.texi (ccos): Likewise. * doc/posix-functions/ccosf.texi (ccosf): Likewise. * doc/posix-functions/ccosh.texi (ccosh): Likewise. * doc/posix-functions/ccoshf.texi (ccoshf): Likewise. * doc/posix-functions/cexp.texi (cexp): Likewise. * doc/posix-functions/cexpf.texi (cexpf): Likewise. * doc/posix-functions/cimag.texi (cimag): Likewise. * doc/posix-functions/cimagf.texi (cimagf): Likewise. * doc/posix-functions/clog.texi (clog): Likewise. * doc/posix-functions/clogf.texi (clogf): Likewise. * doc/posix-functions/conj.texi (conj): Likewise. * doc/posix-functions/conjf.texi (conjf): Likewise. * doc/posix-functions/cpow.texi (cpow): Likewise. * doc/posix-functions/cpowf.texi (cpowf): Likewise. * doc/posix-functions/cproj.texi (cproj): Likewise. * doc/posix-functions/cprojf.texi (cprojf): Likewise. * doc/posix-functions/creal.texi (creal): Likewise. * doc/posix-functions/crealf.texi (crealf): Likewise. * doc/posix-functions/csin.texi (csin): Likewise. * doc/posix-functions/csinf.texi (csinf): Likewise. * doc/posix-functions/csinh.texi (csinh): Likewise. * doc/posix-functions/csinhf.texi (csinhf): Likewise. * doc/posix-functions/csqrt.texi (csqrt): Likewise. * doc/posix-functions/csqrtf.texi (csqrtf): Likewise. * doc/posix-functions/ctan.texi (ctan): Likewise. * doc/posix-functions/ctanf.texi (ctanf): Likewise. * doc/posix-functions/ctanh.texi (ctanh): Likewise. * doc/posix-functions/ctanhf.texi (ctanhf): Likewise. * doc/posix-headers/complex.texi (complex.h): Likewise. 2010-10-07 Jim Meyering parse-datetime: avoid compilation failure on OpenBSD 4.7 * lib/parse-datetime.y (_STDLIB_H) [_STDLIB_H_]: Define.

Instead, use a reliable way to determine whether the 'alias' command works. 2010-09-08 Jim Meyering init.sh: penalize a set-x-impaired shell; don't disqualify it * tests/init.sh: Too many shells corrupt application stderr when you set -x, so we can't afford to disqualify them, since at least on Irix-6.5, that would disqualify all bourne shells. Instead, use a two-pass approach. On the first pass, try to find a shell that meets the stricter condition that set -x does not corrupt stderr. If no shell meets the stricter condition, retest each candidate shell, but without that extra condition. Finally, when VERBOSE=yes is requested and set -x might cause trouble, simply issue a warning and refrain from enabling debug output. 2010-09-08 Eric Blake unsetenv: fix OpenBSD bug * m4/setenv.m4 (gl_FUNC_UNSETENV): Check for OpenBSD bug. * doc/posix-functions/unsetenv.texi (unsetenv): Update documentation.

They make it so with "set -x", environment settings appear in stderr output. For example, this command: /bin/sh -c 'set -x; P=1 true 2> err' 2>/dev/null; cat err prints "P=1" on those two systems: 2010-09-08 Bruno Haible gnulib-tool: Avoid stderr output on IRIX related to 'alias', 'unalias'. * gnulib-tool: Use stderr redirection around the 'alias' and 'unalias' commands, because some shells ignore redirections when there is an error in the command lookup. Reported by Eric Blake. 2010-09-07 Reuben Thomas * lib/regex.h: Fix a mention of `regex_compile' (should be `re_compile_pattern'). Correct and clarify documentation for RE_CONTEXT_INVALID_DUP.

(ldexp): Provide an unused dummy if not available. (scale_radix_exp, parse_number, underlying_strtod): New functions. (strtod): Use them. This implementation prefers to use the underlying strtod if available, falling back on our own code only to fix known bugs. This is more likely to produce an accurate result. Also, it avoids the use of libm functions. * m4/strtod.m4 (gl_FUNC_STRTOD): Don't invoke _AC_LIBOBJ_STRTOD; no longer needed.

This function differs from memcoll in that the NUL byte is part of the argument. Omit the abort-checks, as performance is a real issue here. Plus, the checks were wrong anyway (an off-by-one error). Omit local variable 'diff', as it's a bit clearer that way. * m4/memcoll.m4 (gl_MEMCOLL): Omit AC_FUNC_STRCOLL, as it's no longer needed. 2010-07-08 Chen Guo (x)memcoll: speedup when input is known to be NUL delimited * lib/memcoll.c: Include stdlib.

It ensures that the temporary file, "out", is created in a temporary directory, and removed upon termination. * tests/test-pwrite.sh: Re-add file. * modules/pwrite-tests: Reference it. 2010-05-23 Ralf Wildenhues Fix output redirection buglet in init.sh. * tests/init.sh: Fix redirection of stderr. 2010-05-20 Simon Josefsson * modules/valgrind-tests (configure.ac): Invoke gl_VALGRIND_TESTS. 2010-05-17 Simon Josefsson * modules/valgrind-tests: New file. * m4/valgrind-tests.m4: New file. * doc/valgrind-tests.texi: New file. * doc/gnulib.texi (Running self-tests under valgrind): New section. 2010-05-19 Bruno Haible Clean up dead code in recent commit. * m4/libunistring-base.m4 (gl_LIBUNISTRING_VERSION_CMP): Include the body of gl_LIBUNISTRING_VERSION_CMP_ORIG as fallback. (gl_LIBUNISTRING_VERSION_CMP_ORIG): Remove macro. Suggested by Paolo Bonzini. 2010-05-19 Bruno Haible Avoid valgrind error reports from libunistring. * lib/libunistring.valgrind: New file, based on lib/malloca.valgrind. * modules/libunistring (Files): Add it. * modules/libunistring-optional (Files): Likewise. 2010-05-18 Paolo Bonzini Bruno Haible New module 'libunistring-optional'. * modules/libunistring-optional: New file. * m4/libunistring-base.m4: New file. * m4/libunistring-optional.m4: New file. * lib/unicase.in.h: Renamed from lib/unicase.h. * lib/uniconv.in.h: Renamed from lib/uniconv.h. * lib/unictype.in.h: Renamed from lib/unictype.h. * lib/unilbrk.in.h: Renamed from lib/unilbrk.h. * lib/uniname.in.h: Renamed from lib/uniname.h. * lib/uninorm.in.h: Renamed from lib/uninorm.h. * lib/unistdio.in.h: Renamed from lib/unistdio.h. * lib/unistr.in.h: Renamed from lib/unistr.h. * lib/unitypes.in.h: Renamed from lib/unitypes.h. * lib/uniwbrk.in.h: Renamed from lib/uniwbrk.h. * lib/uniwidth.in.h: Renamed from lib/uniwidth.h. * m4/libunistring.m4 (gl_LIBUNISTRING_CORE): Renamed from gl_LIBUNISTRING.

Fix comment. 2010-05-16 James Youngman doc: update users.txt * users.txt: Add CSSC. 2010-05-16 Jim Meyering init.sh: fix an error in the previous change; add more comments * tests/init.sh: Compare exit code in loop against 9, not 2. Patch by Bruno Haible. Make the two tests more similar by adding an empty "then" clause. Add comments. init.sh: avoid unnecessary shell re-exec * tests/init.sh: Improve the re-exec-required check to first test the current shell. If it passes the test, do not search for a shell that does pass, and do not re-exec. This test is particularly contorted to avoid triggering misbehavior in Solaris 10's /bin/sh whereby any use of $(...) evokes a syntax error and causes immediate shell exit with status 2. Bruno Haible reported that the re-exec made it impossible to single-step through any init.sh-using script. 2010-05-16 Bruno Haible Fix collision between gnulib's and libintl's printf replacements. * lib/stdio.in.h (_GL_STDIO_STRINGIZE, _GL_STDIO_MACROEXPAND_AND_STRINGIZE): New macros. (printf): When using GNU C, map the __printf__ function to rpl_printf via __asm__. When not using GNU C, define rpl_printf instead of __printf__. * lib/printf.c: Ignore DEPENDS_ON_LIBINTL. Undoes the 2010-03-25 commit. * lib/stdio-write.c: Ignore DEPENDS_ON_LIBINTL. Undoes the 2009-08-10 commit. * m4/asm-underscore.m4: New file. * m4/stdio_h.m4 (gl_STDIO_H): Require gl_ASM_SYMBOL_PREFIX. * modules/stdio (Files): Add m4/asm-underscore.m4. (Makefile.am): Substitute ASM_SYMBOL_PREFIX. Reported by Ben Pfaff. 2010-05-16 Bruno Haible verify: Avoid skipping the test on openSUSE 11.0. * tests/test-verify.sh: Unset MALLOC_PERTURB_. 2010-05-13 Bruno Haible Avoid useless warnings from G++. * build-aux/c++defs.h (_GL_CXXALIASWARN_2, _GL_CXXALIASWARN1_2): Don't use _GL_WARN_ON_USE or _GL_WARN_ON_USE_CXX when optimizing. Reported by Jarno Rajahalme . 2010-05-11 Jim Meyering maint.mk: tweak preceding change * top/maint.mk (gl_extract_significant_defines_): Make exclusion regexps tighter by anchoring at EOL, and make the new group "shy" for slightly decreased overhead. 2010-05-11 Eric Blake maint.mk: gnulib doesn't guarantee NSIG * top/maint.mk (gl_extract_significant_defines_): Exclude NSIG. 2010-05-10 Peter O'Gorman test-pwrite.c: Remove unused variable declaration. * tests/test-pwrite.c (main): Remove read_buf declaration. Remove useless test-pwrite.sh file. * tests/test-pwrite.sh: Delete file. * modules/pwrite-tests: Remove references. Reported by Bruno Haible. 2010-05-10 Peter O'Gorman init.sh: fix a typo * tests/init.sh: Correct typo in MALLOC_PERTURB_ initialization. 2010-05-10 Jim Meyering maint.mk: avoid using a temporary file in the always-defined-macros check * top/maint.mk (.re-defmac): Remove rule.

We may need to break them out into a different .h file. (__COUNTER__): Define to 0 if the compiler doesn't support it. (verify) [!defined __cplusplus]: Use them to avoid duplicate decls of verify_function__. 2010-05-05 Peter O'Gorman Tests for module pwrite. * modules/pwrite-tests: New file. * tests/test-pwrite.sh: New file. * tests/test-pwrite.c: New file.

Most fts-using tools must be able to process all arguments, in order, and can be expected to diagnose such arguments themselves. 2009-11-30 Eric Blake utimens: fix compilation error * lib/utimens.c (lutimens) [!HAVE_UTIMENSAT && HAVE_LUTIMES]: Declare variable at right scope. 2009-11-29 Jim Meyering bootstrap: handle perl-5.11's changed --version output * build-aux/bootstrap (get_version): Handle perl separately, since perl-5.11's --version output is different. 2009-11-28 Jim Meyering userspec: depend on the inttostr module, too * modules/userspec (Depends-on): Add inttostr. userspec: disallow an ID that maps to (uid_t)-1 or (gid_t)-1 * lib/userspec.c (parse_with_separator): Do not accept a user ID number of MAXUID when it evaluates to (uid_t) -1. Likewise for group ID. Reported by Matt McCutchen in userspec: reformat to use spaces, not TABs * lib/userspec.c: Expand TABs to spaces.

Using $srcdir (with no double quotes) suffices. However, since tests may be invoked manually, and since you may explicitly set srcdir to the name of a directory containing spaces, do quote its uses here. * tests/test-pread.sh: Likewise. Suggested by Bruno Haible. test-pread.sh: avoid diagnostics for those who ignore SIGPIPE * tests/test-pread.sh: Write no data into the pipe, because test-pread actually reads none. This avoids a diagnostic, "bash: echo: write error: Broken pipe", that arises in the unusual event something is ignoring SIGPIPE, and might be interpreted as some sort of failure. Reported by Bruno Haible. 2009-11-25 Jim Meyering test-pread: cover failure with ESPIPE and EINVAL * tests/test-pread.c (main): Test for failure, too. * tests/test-pread.sh: Invoke with stdin on a pipe.

Typically, a configure-time function-in-library test is performed via code like this: LIB_VAR= AC_SUBST([LIB_VAR]) prefix_saved_LIBS=$LIBS AC_SEARCH_LIBS([FUNC], [LIB_NAME], [test "$ac_cv_search_FUNC" = "none required" || LIB_VAR=$ac_cv_search_FUNC]) LIBS=$prefix_saved_LIBS However, in each of the files affected by this change, the LIB_VAR= initialization was omitted.

At the moment, I want to filter by branch name. Rather than adding a --branch option to gitlog-to-changelog, it seems more flexible to simply pass all options directly to git-log and let git do the work. Notice that this effectively makes --since a redundant option for gitlog-to-changelog, but removing it would require current usage to change since calls would then require an additional '--'. 2008-12-21 Bruno Haible * modules/mbsnrtowcs-tests: New file. * tests/test-mbsnrtowcs1.sh: New file. * tests/test-mbsnrtowcs2.sh: New file. * tests/test-mbsnrtowcs3.sh: New file. * tests/test-mbsnrtowcs4.sh: New file. * tests/test-mbsnrtowcs.c: New file.

Detect pseudo-denormals on x86 even when cross-compiling. * lib/isnan.c (rpl_isnanl) [!KNOWN_EXPBIT0_LOCATION && USE_LONG_DOUBLE && x86]: Add one more check to filter out invalid bit patterns that happen to satisfy ==. Avoid link failures with separate libtests.a. * gnulib-tool (func_emit_tests_Makefile_am): Also list local_ldadd last, to satisfy circular dependencies. 2007-12-11 Eric Blake and Bruno Haible Fix OpenBSD 4.0 handling of long double. * m4/float_h.m4 (gl_FLOAT_H): Also claim OpenBSD is broken. * lib/float.in.h [__OpenBSD__]: Add fixes for OpenBSD. * doc/headers/float.texi (float.h): Document OpenBSD bug. 2007-12-11 Jim Meyering * users.txt: Add libvirt. Support versions of autoconf prior to 2.59c. * gnulib-tool (func_emit_initmacro_done): Define m4_foreach_w if it is not already defined. 2007-12-09 Bruno Haible Let 'gnulib-tool --import' collect sources needed for the tests in tests/ rather than in lib/. * gnulib-tool (func_emit_tests_Makefile_am): Accept use_libtests argument. If true, add rules to generate libtests.a, and put libtests.a into $(LDADD). Consider source files in subdirectories and set uses_subdirs. (func_emit_initmacro_start, func_emit_initmacro_end, func_emit_initmacro_done): Pass all arguments explicitly. (func_import): Determine two module lists main_modules, testsrelated_modules. Determine use_libtests. Determine two variables sed_transform_main_lib_file, sed_transform_testsrelated_lib_file instead of just sed_transform_lib_file. Determine two variables main_files and testsrelated_files. Compute 'files' as the union of both. Adjust sed_rewrite_old_files, sed_rewrite_new_files, func_add_or_update. In the generated gnulib-comp.m4, collect the object files for tests/ in different variables than those for lib/. Substitute LIBTESTS_LIBDEPS. (func_create_testdir): Combine the uses_subdirs results from func_emit_lib_Makefile_am and from func_emit_tests_Makefile_am. 2007-12-09 Bruno Haible * gnulib-tool (func_emit_tests_Makefile_am): Expand references to the build-aux directory. 2007-12-09 Bruno Haible * gnulib-tool (func_emit_tests_Makefile_am): Remove redundant code introduced on 2006-09-09. 2007-12-07 Jim Meyering Let these macros work also with autoconf-2.59. * m4/getline.m4 (gl_FUNC_GETLINE): Require only autoconf-2.59. 2.60 is not needed, since gnulib now permits use of AC_CHECK_DECLS_ONCE. * m4/getdelim.m4 (gl_FUNC_GETDELIM): Likewise. 2007-12-06 Jim Meyering Avoid a configure-time syntax error in gl_FUNC_ACL. * m4/acl.m4 (gl_FUNC_ACL): Be careful to check for the acl_trivial function in each branch, before testing the cache variable. 2007-12-04 Eric Blake Make scripts executable. * build-aux/config.guess: Add execute permissions. * build-aux/config.sub: Likewise. * build-aux/gendocs.sh: Likewise.

Make cygwin fseeko check more reliable. * m4/stdio_h.m4 (gl_STDIN_LARGE_OFFSET) [__CYGWIN__]: Use cygwin version numbers, rather than unrelated feature check. * doc/functions/fseeko.texi (fseeko): Tweak failure report. * doc/functions/ftello.texi (ftello): Likewise. Reported by Bruno Haible. * m4/strerror.m4: Bump version number. 2007-12-03 Bruno Haible * doc/functions/mprotect.texi: Mention the mingw problem. 2007-12-03 Eric Blake * m4/strerror.m4 (gl_FUNC_STRERROR_SEPARATE): Ensure REPLACE_STRERROR is initialized before this macro. 2007-12-03 Paul Eggert Add support for Solaris 10 ACLs. Also, ACLs are Gnulib, not Autoconf. * modules/acl (configure.ac): Rename AC_FUNC_ACL to gl_FUNC_ACL. * m4/acl.m4 (gl_FUNC_ACL): Renamed from AC_FUNC_ACL. On Solaris, put -lsec in even for programs other than 'ls'. This fixes a problem for gettext reported by Bruno Haible in . * lib/acl.c (copy_acl, qset_acl) [USE_ACL && defined ACL_NO_TRIVIAL]: Add support for Solaris 10. This isn't efficient, but should get the job done for now. 2007-12-03 James Youngman * doc/regexprops-generic.texi: change "an close-group" to "a close-group" and "illegal" to "not allowed". 2007-11-23 Ralf Wildenhues * lib/unictype/pr_byname.c: Include unictype/pr_byname.h instead of pr_byname.h. Needed for the rare case when the maintainer has done "make maintainer-clean" in the source directory and then attempts a build outside the source directory. * lib/unictype/scripts.c: Include unictype/scripts_byname.h instead of scripts_byname.h. 2007-12-02 Martin Lambers Bruno Haible * lib/getpagesize.h: Remove file. * lib/unistd.in.h: Include declaration of getpagesize here. * m4/getpagesize.m4 (gl_FUNC_GETPAGESIZE): Renamed from gl_GETPAGESIZE.

(Depends-on): Add unistd. (configure.ac): Invoke gl_UNISTD_MODULE_INDICATOR. (Include): Use instead of getpagesize.h. * modules/unistd (Makefile.am): Substitute also GNULIB_GETPAGESIZE, HAVE_GETPAGESIZE, HAVE_OS_H, HAVE_SYS_PARAM_H. * m4/pagealign_alloc.m4 (gl_PREREQ_PAGEALIGN_ALLOC): Remove gl_GETPAGESIZE invocation, already handled by module dependency. * lib/pagealign_alloc.c: Don't include getpagesize.h. 2007-12-02 Bruno Haible * modules/strings-tests: New file. * tests/test-strings.c: New file. Move declarations of str{,n}casecmp from to . * lib/strings.in.h: New file. * lib/string.in.h (strcasecmp, strncasecmp): Remove declarations. * m4/strings_h.m4: New file. * m4/string_h.m4 (gl_HEADER_STRING_H_DEFAULTS): Remove initialization of HAVE_STRCASECMP, HAVE_DECL_STRNCASECMP. * modules/strings: New file. * modules/string (Makefile.am): Update. * modules/strcase (Include): Mention , not . Reported by Karl Berry. 2007-12-01 Eric Blake * m4/stdio_h.m4 (gl_STDIN_LARGE_OFFSET) [__CYGWIN__]: Rewrite to accommodate fix in cygwin 1.5.25. 2007-12-01 Jim Meyering Fix a bug that inhibited much of the utf8-optimization in regcomp.c. * lib/regcomp.c (optimize_utf8): Fix a typo, s/idx/ctx_type/, that would inhibit utf8-optimization of a regexp containing line- or buffer-anchors, e.g., `^', `$'. 2007-11-30 Bruno Haible * lib/lock.h (gl_recursive_lock_init) [PTHREAD && PTHREAD_RECURSIVE_MUTEX_INITIALIZER]: Call glthread_recursive_lock_init. * lib/lock.c (glthread_recursive_lock_init) [PTHREAD_RECURSIVE_MUTEX_INITIALIZER]: New function. Reported by Yoann Vandoorselaere . 2007-11-28 Paul Eggert New function qset_acl, like set_acl but with syscall semantics. * lib/acl.h (qset_acl): New decl. * lib/acl.c (qset_acl): New function. (set_acl): Use new function. Use more-consistent diagnostics. 2007-11-28 Jim Meyering * modules/physmem (License): Change from GPL to LGPLv2+. 2007-11-26 Bruno Haible * lib/vasnprintf.c (decode_long_double): Don't abort if the 'long double' type has excess precision. Reported by Jim Meyering in . 2007-11-25 Ralf Wildenhues * doc/fdl.texi, doc/gpl-3.0.texi, doc/lgpl-3.0.texi: Sync from . * modules/agpl-3.0, doc/agpl-3.0.texi: New module, with license text from same location. * doc/maintain.texi, doc/standards.texi: Sync from . 2007-11-22 Ondřej Vašík and Jim Meyering Adjust getdate' grammar to accept a slightly more regular language. E.g., accept "YYYYMMDD +N days" as well as "YYYYMMDD N days". Before, the former was rejected. * lib/getdate.y (digits_to_date_time): New function, factored out of ... (number): ...here. Just call digits_to_date_time. (hybrid): New non-terminal to handle an sequence consistently. 2007-11-18 Jim Meyering Pull my changes from coreutils: bootstrap: fix typo to enable use of $gnulib_tool_option_extras. * build-aux/bootstrap (gnulib_tool_options): Add a space before the use of $gnulib_tool_option_extras, so that it's separated from the preceding argument. Fix bootstrap failure to handle files like lib/uniwidth/cjk.h. * build-aux/bootstrap (cp_mark_as_generated): Create any required parent destination directories before copying a file into place. 2007-11-18 Sergey Poznyakoff bootstrap: work also with 4-argument variant of AC_INIT * build-aux/bootstrap (gnulib_extra_files): Adjust sed command. 2007-11-16 Paul Eggert Port test-getaddrinfo to Solaris. Problem reported by Bruno Haible in . * tests/test-getaddrinfo.c (simple): Add a comment asking for an explanation of setting 'hints'. Don't reject an implementation merely because it returns EAI_SERVICE. (EAI_SERVICE): Define to 0 if not defined. 2007-11-15 Paul Eggert The license of gnu-make and posix-shell is now "GPLed build tool". * modules/gnu-make (License): Likewise. * modules/posix-shell (License): Likewise. New module posix-shell, for determining a POSIX shell or perhaps something that is close enough to a POSIX shell. * m4/posix-shell.m4: New file. * modules/posix-shell: New file. * MODULES.html.sh: Mention new module. New module gnu-make, for determining whether we're using GNU Make. * m4/gnu-make.m4: New file. * modules/gnu-make: New file. * MODULES.html.sh: Mention new module. 2007-11-14 Jim Meyering Define a sometimes-link-required function using ARGMATCH_DIE_DECL. * tests/test-argmatch.c (ARGMATCH_DIE_DECL): When defined, use this macro to create a function _definition_. Remove useless "#undef ARGMATCH_DIE". 2007-11-14 Bruno Haible * lib/config.charset: Update for OpenBSD 4.1. Reported and helped by Ben Pfaff . 2007-11-12 Paul Eggert Document 64-bit #if problems in stdint.texi. * doc/headers/stdint.texi (stdint.h): Mention problems with 64-bit-#if, and how to work around them. Don't insist on 'long long int' support in the preprocessor. It breaks too many things. For example, PRIdMAX still uses a 'long long int' format with the latest Sun compiler, even though HAVE_LONG_LONG_INT isn't defined due to that compiler's preprocessor problem. This causes the latest coreutils to dump core on Solaris 10 sparc with the Sun C compiler. Instead, fix the 2007-10-16 problem in a different way, by evaluating the troublesome expressions at configure-time, not at #if-time. * m4/longlong.m4 (_AC_TYPE_LONG_LONG_SNIPPET): Don't test the preprocessor. * m4/inttypes.m4 (gl_INTTYPES_H): Move the #if checks into compile-time C checks, done at 'configure'-time. (gl_INTTYPES_CHECK_LONG_LONG_INT_CONDITION): New macro. * modules/inttypes (Makefile): Substitute the new symbols that gl_INTTYPES_H now generates. * lib/inttypes.in.h: Don't use constants wider than 'long' in #if. 2007-11-12 Bruno Haible Tests for Unicode character classification functions. * modules/unictype/bidicategory-byname-tests: New file. * modules/unictype/bidicategory-name-tests: New

Presuming the "can't happen" condition is true, that narrowing could conceivably convert an invalid st_size value into a valid one. Instead, use a change based on Matthew Woehlke's original patch. Slight readability improvement: use an assert-like macro in place of literal "abort ()" uses. * lib/fts.c (fts_assert): Define. (fts_set_stat_required, cwd_advance_fd, fts_read, fd_ring_check): Use this macro instead of a bare 'abort'. 2007-01-05 Paul Eggert Don't worry about using IRIX 5.3's wctype.h broken definitions; simply work around them. * lib/wctype_.h: Remove test for HAVE_WCTYPE_CTMP_BUG. (iswalnum, iswalpha, iswblank, iswcntrl, iswdigit, iswgraph, iswlower): (iswprint, iswpunct, iswspace, iswupper, iswxdigit): Undef before declaring. Don't bother to define as macros, since the standard doesn't require it. * m4/wctype.m4 (WCTYPE_H, ABSOLUTE_WCTYPE_H): Simplify, since we no longer worry about IRIX 5.3. (HAVE_WCTYPE_CTMP_BUG): Remove. 2007-01-04 Paul Eggert * lib/wctype_.h (_ctmp_) [HAVE_WCTYPE_CTMP_BUG]: Now of type wchar_t, not wint_t. Also, include , to fix another IRIX bug. * m4/wctype.m4 (gl_WCTYPE_H): Likewise. Problems reported by Georg Schwarz for IRIX 5.3. * gnulib-tool (autoconf_minversion): Take the maximum version number found, not the minimum. Problem reported by James Youngman. 2007-01-03 Karl Berry * doc/error.texi: new file, explaining interaction with progname. * doc/gnulib.texi: include it.

Count errors to compute the return value. Reorder the code a bit to be easier to follow. Don't set event bits that were not requested (except POLLERR and POLLHUP). 2007-01-01 Bruno Haible * modules/lchmod (Include): Require lchmod.h, not lchown.h. 2007-01-03 Jim Meyering * modules/fts-lgpl (Depends-on): Add i-ring. Reported by Bruno Haible. 2007-01-02 Bruno Haible * modules/settime (Include): Require timespec.h. * modules/nanosleep (Include): Likewise. 2007-01-01 Bruno Haible * gnulib-tool (func_emit_copyright_notice): Bump year. (func_get_autoconf_snippet): Emit a GNULIB_ macro. 2007-01-01 Bruno Haible Improve support for OpenBSD. * build-aux/config.rpath (libname_spec): Export. (library_names_spec): New variable. Export. * m4/lib-link.m4 (AC_LIB_LINKFLAGS_BODY): Extract libname_spec and library_names_spec from the config.rpath output. Locate shared library through the name pattern in library_names_spec. 2007-01-01 Eric Blake * lib/version-etc.c (COPYRIGHT_YEAR): Bump for new year. 2006-12-30 Paul Eggert * gnulib-tool (SORT): Remove, since we no longer assume GNU sort. Rewrite so as not to assume GNU sort or "tail -1". Also, don't assume the C locale, and avoid an "eval" that could cause trouble. Problem with SORT reported by Bob Proulx. * lib/getpagesize.h (getpagesize) [defined __amigaos4__]: Define. Trivial patch from Henning Nielsen Lund, originally sent to bug-grep@gnu.org today. 2006-12-29 Paul Eggert * lib/acl.h: Include sys/types.h and sys/stat.h, for mode_t and struct stat. Problem reported by Henning Nielsen Lund. * lib/acl.c: Include acl.h first, to check interface. Don't bother to include sys/types.h and sys/stat.h again. 2006-12-28 Paul Eggert Import the following change from libc; problem reported by Sven Verdoolaege. 2005-10-13 Ulrich Drepper [BZ #1373] * lib/argp.h: Remove __NTH for __argp_usage inline function. 2006-12-28 Jim Meyering * build-aux/announce-gen: Do not assume that the package builds any of tar.gz, tar.bz2, and .xdelta files. Suggestion from Simon Josefsson. 2006-12-28 Simon Josefsson * modules/announce-gen: New file. 2006-12-27 Paul Eggert * lib/mbchar.h: Just include ; the wctype module handles its gotchas now. * lib/mbswidth.c: Likewise. * lib/wcwidth.h: Likewise. * m4/mbchar.m4 (gl_MBCHAR): Don't bother checking for wctype.h and iswcntrl; the wctype module does this stuff now. * m4/mbswidth.m4 (gl_MBSWIDTH): Likewise. * m4/wcwidth.m4 (gl_FUNC_WCWIDTH): Likewise. * modules/mbchar (Depends-on): Add wctype. * modules/mbswidth (Depends-on): Likewise. * modules/wcwidth (Depends-on): Likewise. 2006-12-27 Eric Blake * lib/fnmatch.c: Reinstate inclusion of , since this module uses more than what is required to provide. 2006-12-26 Eric Blake * gnulib-tool (sed_extract_prog): Avoid space-tab. 2006-12-26 Eric Blake * modules/absolute-header: New module. * modules/fcntl (Depends-on): Depend on it. * modules/inttypes (Depends-on): Likewise. * modules/stdint (Depends-on): Likewise. * modules/sys_stat (Depends-on): Likewise. * modules/wctype (Depends-on): Likewise. * MODULES.html.sh (Support for building libraries and executables): Document it. 2006-12-25 Paul Eggert * gnulib-tool (SED): Remove, undoing previous change. The problem was that it broke coreutils on Solaris, because "sed --posix" leaked into a makefile. (sed): New alias, if 'alias' and GNU sed. 2006-12-24 Jim Meyering Work around an fchownat bug in glibc-2.4: http://lists.ubuntu.com/archives/ubuntu-users/2006-September/093218.html This bug would cause "chown -RP ... DIR" to follow symlinks in DIR, in spite of the -P option. * m4/openat.m4 (gl_FUNC_FCHOWNAT, gl_FUNC_FCHOWNAT_DEREF_BUG): New macros. (gl_PREREQ_OPENAT): Require gl_FUNC_FCHOWNAT. * modules/openat (Files): Add lib/fchownat.c. * lib/openat.c (fchownat): Don't define here. Move to... * lib/fchownat.c: ...this new file. 2006-12-23 Paul Eggert Fix bug reported by Bruno Haible in where quotearg.c didn't compile on Mac OS X 10.2 because it lacks and wint_t. * lib/wctype_.h (__wctype_wint_t): New type. Include , , only if HAVE_WINT_T. (iswalnum, iswalpha, iswblank, iswcntrl, iswdigit, iswgraph): (iswlower, iswprint, iswpunct, iswspace, iswupper, ixwxdigit): Arg is now of type __wctype_wint_t, not wint_t. * m4/wctype.m4 (gl_WCTYPE_H): Require gt_TYPE_WINT_T, and substitute HAVE_WINT_T. * modules/wctype (Files): Add m4/wint_t.m4. (wctype.h): Substitute HAVE_WINT_T. 2006-12-23 Bruno Haible * lib/safe-read.h [C++]: Wrap declarations in extern "C". 2006-12-23 Bruno Haible * lib/canonicalize-lgpl.c (__realpath): Test HAVE_READLINK instead of S_ISLNK. Needed because gnulib's sys/stat.h replacement defines S_ISLNK on mingw. 2006-12-22 Bruno Haible * lib/copy-file.c: Include acl.h. (copy_file_preserving) [USE_ACL]: Use copy_acl instead of chmod. Close the file descriptors only after being done with copy_acl. * modules/copy-file (Depends-on): Add acl. 2006-12-22 Bruno Haible * gnulib-tool (SED): New variable. Use $SED instead of sed everywhere. 2006-12-22 Bruno Haible * modules/no-c++: New file. * m4/no-c++.m4: New file. * MODULES.html.sh (Support for building libraries and executables): Add no-c++. 2006-12-22 Paul Eggert * m4/mktime.m4 (AC_FUNC_MKTIME): Sync from Autoconf. Include , and use its INT_MAX to rewrite the j loop so that it does not overflow 'int'. Problem reported by Ralf Wildenhues in . Play it safe by shifting left by 1 rather than multiplying by 2, as GCC is less likely to optimize this away when the value is signed (when it assumes overflow leads to undefined behavior). Also, don't assume time_t uses two's complement. 2006-12-21 Paul Eggert * MODULES.html.sh: New module wctype. * lib/wctype_.h, m4/wctype.m4, modules/wctype: New files. * lib/fnmatch.c: Don't bother to include before , since the new wctype module should fix this. * lib/quotearg.c: Include unconditionally, since the wctype module should arrange for it. * lib/regex_internal.h: Likewise. * m4/quotearg.m4 (gl_QUOTEARG): Don't check for wctype.h or iswprint, since the wctype module should handle this now. * m4/regex.m4 (gl_PREREQ_REGEX): Don't check for wctype.h. * modules/fnmatch (Depends-on): Add wctype. * modules/quotearg (Depends-on): Likewise. * modules/regex (Depends-on): Likewise. 2006-12-19 Bruno Haible * lib/strdup.h [C++]: Wrap definitions in extern "C". Suggested by Lorenzo Bettini . 2006-12-19 Ralf Wildenhues * modules/savewd (Depends-on): Fix dependency on fcntl. 2006-12-18 Paul Eggert * m4/stdint.m4 (gl_STDINT_H): Set STDINT_H to empty if stdint.h conforms to C99, rather than relying on the user's environment setting of STDINT_H. 2006-12-18 Paul Eggert and Eric Blake * lib/dirname.h (DOUBLE_SLASH_IS_DISTINCT_ROOT): Default to 0, not 1. This is more consistent with the other defines here. * m4/double-slash-root.m4 (gl_DOUBLE_SLASH_ROOT): Port to z/OS. Problem reported by Paul Gilmartin. Change local vars to use gl_ prefix rather than ac_. Don't define DOUBLE_SLASH_IS_DISTINCT_ROOT to 0, for consistency with other defines. * modules/double-slash-root: New module. * modules/dirname (Files): Remove m4/double-slash-root.m4. (Depends-on): Add double-slash-root. * MODULES.html.sh (File system functions): Mention new module. 2006-12-14 Paul Eggert * lib/yesno.c [!ENABLE_NLS]: Don't include getline.h. (yesno) [!ENABLE_NLS]: Don't invoke getline or rpmatch. This is for the benefit of gzip, which doesn't do i18n. 2006-12-12 Jim Meyering * m4/acl.m4 (gl_ACL_GET_FILE): Fix logic error. Reported by Andreas Schwab . 2006-12-12 Bruno Haible Merge these changes. 2006-09-05 Bruno Haible * lib/iconvme.c (iconv_string): No need to save and restore errno when iconv_alloc succeeded. (iconv_alloc): Don't assume that malloc() or realloc(), when failing, sets errno to ENOMEM. (malloc on GNU/kFreeBSD doesn't.) No need to test for " && dest " at the end - dest is always != NULL there. Call iconv with 4xNULL arguments initially, to reset the state. Call iconv with 2xNULL arguments, also to flush the state storage. Handle the IRIX iconv behaviour. Realloc the final result, to throw away unused memory. 2006-12-11 Paul Eggert * m4/openat.m4 (gl_FUNC_OPENAT): Don't compile mkdirat and fchmodat unconditionally, since glibc 2.4 has them. Problem reported by Arkadiusz Miskiewicz. 2006-12-10 Bruno Haible * gnulib-tool (func_import): Show the include files only for those modules that are copied and specified. Reported by Karl Berry. 2006-12-08 Jim Meyering * build-aux/announce-gen ($VERSION): Don't use of $Revision...$. Instead, use Emacs' time-stamp write hook. Note that the time is UTC. * build-aux/announce-gen: Add two new options, both optional: --bootstrap-tools=TOOL_LIST a comma-separated list of tools, e.g., autoconf,automake,bison,gnulib --gnulib-snapshot-date=DATE if gnulib is in the bootstrap tool list, then report this as the snapshot date. If not specified, use the current date/time. If you specify a date here, be sure it's UTC. 2006-12-05 Ralf Wildenhues * tests/test-argp-2.sh: Fix test to match actual output. (func_compare): Fix sed script to be portable. 2006-12-05 Paul Eggert * lib/utimens.c (futimens) [HAVE_BUGGY_NFS_TIME_STAMPS]: Add a workaround for this case. It is not autoconfigured now; offhand it's hard to see how to autoconfigure it. 2006-12-03 Paul Eggert * lib/mkdir-p.c (make_dir_parents): Fix race condition when making a directory that is about to be chowned. Such a directory's initial file permissions should permit the owner only and this should not be changed until after the chown, since the group and other bits would be incorrect if they granted permission before the chown. Fix porting problem for iswctype reported by Georg Schwarz in: http://lists.gnu.org/r/bug-coreutils/2006-12/msg00017.html * lib/fnmatch.c (WIDE_CHAR_SUPPORT): Require HAVE_ISWCTYPE, too. * lib/regex_internal.h (RE_ENABLE_I18N): Likewise. * m4/fnmatch.m4 (_AC_LIBOBJ_FNMATCH): Check for iswctype, too. * m4/regex.m4 (gl_PREREQ_REGEX): Likewise. 2006-12-03 Jim Meyering * lib/fts.c (fts_load): Don't set sp->fts_dev here, since p->fts_statp may not yet be defined. (fts_read): Instead, set it in the caller, once p->fts_statp is sure to be defined, and corresponds to a top-level directory. This bug made du -x fail. Here's the coreutils test case: http://git.sv.gnu.org/gitweb/?p=coreutils.git;a=commit;h=ba45154d8e9f Reported by Mike Frysinger. 2006-12-01 Jim Meyering * modules/savewd (Depends-on): Add fcntl_h to avoid self-test build failure due to missing definition of HAVE_WORKING_O_NOFOLLOW. Reported by Simon Josefsson. 2006-11-30 Jim Meyering * m4/warning.m4: Use the all-permissive copyright notice recommended by RMS (rather than LGPL). * m4/vararrays.m4: Likewise. * m4/flexmember.m4: Likewise. 2006-11-29 Bruno Haible * gnulib-tool (func_emit_lib_Makefile_am): Initialize also noinst_LIBRARIES. Augment noinst_LIBRARIES and noinst_LTLIBRARIES using +=. Reported by Simon Josefsson . 2006-11-28 James Youngman * README: Advise users that they might find the bug-gnulib@gnu.org and autotools-announce@gnu.org mailing lists useful. 2006-11-28 Bruno Haible * m4/ptrdiff_max.m4: Remove file. 2006-11-21 Bruno Haible * m4/eoverflow.m4 (gl_EOVERFLOW): Use AC_COMPUTE_INT instead of _AC_COMPUTE_INT. (AC_COMPUTE_INT): Add fallback definition for autoconf < 2.61. * m4/ptrdiff_max.m4 (gl_PTRDIFF_MAX): Use AC_COMPUTE_INT instead of _AC_COMPUTE_INT. (AC_COMPUTE_INT): Add fallback definition for autoconf < 2.61. * m4/size_max.m4 (gl_SIZE_MAX): Use AC_COMPUTE_INT instead of _AC_COMPUTE_INT. (AC_COMPUTE_INT): Add fallback definition for autoconf < 2.61. 2006-11-28 Jim Meyering * lib/regcomp.c (parse_branch): Rename local, exp->expr, to avoid warning from "gcc -Wshadow" about shadowing the builtin. 2006-11-27 Bruno Haible * m4/stdint.m4 (gl_STDINT_BITSIZEOF): Use AC_COMPUTE_INT instead of _AC_COMPUTE_INT. (AC_COMPUTE_INT): Add fallback definition for autoconf < 2.61. 2006-11-27 Bruno Haible Paul Eggert * lib/regex.h (__restrict_arr): Redo logic of #if, for clarity. 2006-11-26 Bruno Haible * gnulib-tool (func_emit_lib_Makefile_am): Initialize also noinst_LTLIBRARIES. 2006-11-27 Paul Eggert Bruno Haible * lib/gettext.h (_LIBGETTEXT_HAVE_VARIABLE_SIZE_ARRAYS): Define to 0 if compiling with "gcc -ansi". 2006-11-26 Paul Eggert Fix some incompatibilities with gcc -ansi -pedantic. * lib/regex.h (__restrict_arr): Don't use the [restrict] syntax if compiling pedantically with GCC, unless it's C99 or later. Don't trust sys/cdefs.h's definition of __restrict_arr, either, as it mishandles gcc -ansi -pedantic as well. * lib/regex_internal.h (re_token_t): Don't use enum bitfields if gcc -pedantic. * lib/regexec.c (check_node_accept_bytes): Don't use auto initializers for struct if -pedantic, unless it's C99 or later. 2006-11-25 Nix (tiny change) * m4/fcntl_h.m4 (gl_FCNTL_H): Test the atime, not the mtime. Don't close an fd more than once. Identical atimes indicate success, not failure. 2006-11-22 Robinson Mittmann (tiny change) * lib/sincosl.c (kernel_sinl): Fix typo in threshold. 2006-11-23 Jim Meyering * build-aux/announce-gen: New file. From coreutils. 2006-11-22 Jim Meyering Work around a compile-time error from the HP-UX 11.00 /bin/cc. * lib/fts.c (enum Fts_stat): Give this previously-anon enum a name. (fts_read): Use a temporary to narrow the overused st_size member before using it in a switch statement. Reported by Matthew Woehlke. * m4/clock_time.m4 (gl_CLOCK_TIME): Quote AC_SUBST argument. * m4/euidaccess.m4 (gl_PREREQ_EUIDACCESS): Likewise. 2006-11-20 Bruno Haible * gettext.m4 (AM_GNU_GETTEXT): Revert 2005-07-28 patch: Use changequote instead of pairs of brackets. Reported by Andreas Schwab . 2006-11-21 Jim Meyering * lib/fts.c (fts_safe_changedir): Move a declaration "up", so as to remain compatible with older compilers. Patch from Michael Deutschmann. 2006-11-20 Paul Eggert * MODULES.html.sh (File system functions): Add openat. * lib/openat.h (rpl_fstatat): New macro, if [HAVE_OPENAT && ! LSTAT_FOLLOWS_SLASHED_SYMLINK. (fstatat): Define to rpl_fstatat under the same conditions, unless COMPILING_FSTATAT. * m4/openat.m4 (gl_FUNC_OPENAT): Compile fstatat.c too, if fstatat seems to have the bug. * lib/fstatat.c: New file. * modules/openat (Files): Add it. 2006-11-20 Bruno Haible * Makefile: New file. 2006-11-20 Jim Meyering The beginnings of syntax-related checks for gnulib. * lib/Makefile: New file. * lib/t-idcache: New script. Ensure that the two halves of idcache.c stay in sync. * lib/idcache.c: Adjust comments in user- and group- portions to be more accurate, and to be consistent with one another. 2006-11-20 Jim Meyering * lib/idcache.c: Restore most of the 2006-11-06 patch, so as to continue using the flexible array member (thus, this module performs half as many malloc calls), with the addition that... (getgroup, getuser): Consistently record a non-match via an empty "name" string, and map an empty string match to a NULL return value. * modules/idcache (Depends-on): Re-add flexmember. * lib/idcache.c (getuser): Remove all uses of the register keyword. (getuidbyname, getgroup, getgidbyname): Likewise. Use cleaner syntax: NULL rather than 0. * lib/idcache.c (getuidbyname, getgidbyname): Return NULL, not 0. 2006-11-20 Paul Eggert * lib/idcache.c: Undo most recent patch, dated 2006-11-06. It mishandled the case where the group was missing. Problem reported by Greg Schafer. * modules/idcache: Likewise. 2006-11-18 Jim Meyering * check-module (%exempt_header): Add exception for some conditionally-included headers. * modules/i-ring (Depends-on): Add verify. (License): Change to LGPL. 2006-11-16 Paul Eggert * modules/getaddrinfo (Depends-on): Remove inttostr; add snprintf. * lib/getaddrinfo.c: Include snprintf.h rather than intprops.h and inttostr.h. Use snprintf rather than uinttostr, so that LGPLed code doesn't depend on GPLed. 2006-11-17 Paul Eggert * modules/inline (License): Change from GPL to LGPL. 2006-11-17 Jim Meyering * modules/d-type (License): Switch to LGPL. 2006-11-15 Bruno Haible * m4/alloca.m4 (gl_FUNC_ALLOCA): Fix the AC_CACHE_CHECK message. 2006-11-15 Eric Blake * m4/allocsa.m4 (gl_ALLOCSA): Don't invoke macro already picked up by the module dependency. 2006-11-15 Yoann Vandoorselaere Bruno Haible * gnulib-tool (func_create_testdir): Add license consistency check. 2006-11-15 Eric Blake * m4/alloca.m4 (gl_FUNC_ALLOCA): Use AC_CACHE_CHECK to avoid a random "(cached)" in configure output. 2006-11-14 Ralf Wildenhues * m4/inttypes.m4 (gl_INTTYPES_H): Use AC_CACHE_CHECK so that the test for conforming inttypes.h is both announced and cached. * MODULES.html.sh (seen_modules, seen_files): New variables. (func_module): Rewrite to use a few less gnulib-tool and sed invocations. Avoid a couple of quadratic algorithms for ... (missed_modules, missed_files): ... these, with ... (func_append, func_tmpdir): ... these new functions, from gnulib-tool. Analogously, install traps for cleanup. * tests/test-gc.c (main): Remove unused variables. * tests/test-read-file.c: Include stdlib.h, for 'free'. 2006-11-14 Paul Eggert * modules/inttostr (License): Change to LGPL. 2006-11-14 Eric Blake * modules/tempname (License): Change to LGPL. 2006-11-14 Eric Blake * doc/functions.texi (Function Portability): *printf functions on Cygwin now understand all POSIX size specifiers. 2006-11-14 Bruno Haible * modules/c-ctype (License): Change to LGPL. 2006-11-12 Bruno Haible * m4/lib-link.m4 (AC_LIB_LINKFLAGS, AC_LIB_HAVE_LINKFLAGS, AC_LIB_LINKFLAGS_BODY): Also set a LIB${NAME}_PREFIX variable. Needed for GNOME libraries, for which the include files are installed in subdirectories of $prefix/include. 2006-11-12 Bruno Haible * m4/lib-link.m4: Require at least autoconf-2.54. (AC_LIB_LINKFLAGS_BODY) [autoconf < 2.61]: Turn dots into the library name to underscores for the --with option. 2006-11-13 Bruno Haible * gnulib-tool (func_create_testdir): Set gl_source_base correctly in the tests directory. Reported by Ralf Wildenhues. 2006-11-13 Bruno Haible * gnulib-tool (func_emit_initmacro_start): Also override AC_LIBSOURCES. (func_emit_initmacro_end): Undo the override here. (func_emit_initmacro_done): Emit a definition for gl_LIBSOURCES. Works around the famous automake error in coreutils. 2006-11-13 Eric Blake * lib/gl_anytree_oset.h (gl_tree_search_atleast): Return the element, not its node. 2006-11-12 Bruno Haible * gnulib-tool (func_emit_lib_Makefile_am): Replace occurrences of '$(top_srcdir)/build-aux/', taking into account the real auxdir. 2006-11-12 Bruno Haible * gnulib-tool: New option --local-symlink. (func_usage): Document it. (lsymbolic): New variable. (func_import, func_create_testdir): If --symlink was not specified, test whether --local-symlink was specified and the file comes from the local_gnulib_dir. 2006-11-12 Bruno Haible * gnulib-tool (func_ln): New function. (func_ln_if_changed, func_create_testdir): Use it instead of "ln -s". 2006-11-12 Bruno Haible Finish support for source files in subdirectories. * gnulib-tool (func_emit_lib_Makefile_am): If some of the source files are in subdirectories, set uses_subdirs and add 'subdir-objects' to AUTOMAKE_OPTIONS. (func_import, func_create_testdir): Invoke AM_PROG_CC_C_O in this case. 2006-11-12 Bruno Haible * gnulib-tool (func_get_automake_snippet): Synthesize also an EXTRA_lib_SOURCES augmentation. (func_emit_lib_Makefile_am): Initialize EXTRA_lib..._SOURCES to empty. 2006-11-12 Jim Meyering Make fts (in FTS_CWDFD mode) more efficient by caching a few open file descriptors. This also averts a failure on systems with native openat support when a traversed directory lacks "x" access. * lib/fts_.h: Include "i-ring.h" (struct FTS) [fts_fd_ring]: New member. * lib/fts.c (RESTORE_INITIAL_CWD): Also call fd_ring_clear. (FCHDIR): Add parentheses. (fd_ring_check, fd_ring_print) [!FTS_DEBUG]: Define away. (cwd_advance_fd): Add a 3rd parameter. Adjust all callers. When descending, rather than simply closing the previous fts_cwd_fd value, push that file descriptor onto the ring. (same_fd, fd_ring_print, fd_ring_check) [FTS_DEBUG]: New functions. (fts_open): Initialize the new fd_ring member. (fts_close): Clear the ring. (fts_safe_changedir): When possible, use our new fd_ring to skip the diropen and fstat and dev/ino comparison that would normally accompany a virtual `chdir ("..")'. * modules/fts (Depends-on): Add i-ring. * modules/i-ring: New module. * lib/i-ring.c, lib/i-ring.h, lib/i-ring-test.c: New files. * m4/i-ring.m4: New file. 2006-11-12 Ralf Wildenhues * gnulib-tool (func_create_testdir): Fix replacement of `build-aux' in configure.ac. Run autotools in gltests subdirectory. (func_create_testdir, func_create_megatestdir, test): There is no need for '--force' in most autotool invocations in a new tree. Actually fail the whole test if any of the tools, or the configure or make stages fail. Sync from Automake. * build-aux/gnupload: Revert last change. Add pointer to upload instructions of the GNU Maintenance Instructions. Suggestion by Karl Berry. 2006-11-10 Jim Meyering * lib/fts.c [FTS_DEBUG]: Don't try to print a pointer via %s. 2006-11-09 Paul Eggert * lib/gettext.h (dgettext, dcgettext, ngettext) [! ENABLE_NLS]: (dngettext, dcngettext, bindtextdomain) [! ENABLE_NLS]: (bind_textdomain_codeset) [! ENABLE_NLS]: Evaluate all the arguments. That way, callers get compatible behavior if the arguments have side effects. Also, it avoids some GCC diagnostics in some cases; Joel E. Denny reported problems when Bison was configured with --enable-gcc-warnigs. 2006-11-10 Jim Meyering * m4/inline.m4 (gl_INLINE): Check with the compiler, not cpp, so that relevant options in CFLAGS (like -O, -fno-inline) are taken into account. 2006-11-10 Jim Meyering * modules/inline: New file/module. * modules/xalloc (Files): Remove m4/inline.m4. (Depends-on): Add inline, instead. * modules/oset: Likewise. * modules/list: Likewise. 2006-11-09 Paul Eggert * lib/stdint_.h (uintmax_t): Fix typo: int64_t -> uint64_t. Problem reported by Matthew Woehlke. 2006-11-09 Bruno Haible * lib/tempname.c (gen_tempname): Remove variant that invokes __gen_tempname. * m4/tempname.m4 (gl_FUNC_GEN_TEMPNAME): Don't test for __gen_tempname. 2006-11-08 Bruno Haible * m4/longlong.m4 (AC_TYPE_LONG_LONG_INT): Set ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'. 2006-11-08 Paul Eggert * lib/quotearg.h (quotearg_free): New decl. * lib/quotearg.c (quotearg_free): New function. (slot0, nslots, slotvec0, slotvec): Now file-scope so that quotearg_free can get at them. 2006-11-08 Ralf Wildenhues Sync from Automake. * build-aux/gnupload: Add missing 'gnu' to example URL. Report by Karl Berry. 2006-11-08 Bruno Haible * m4/inline.m4 (gl_INLINE): Also test __NO_INLINE__. Suggested by Paul Eggert. 2006-11-08 Jim Meyering * lib/fts.c [!_LGPL_PACKAGE]: Don't include fcntl--.h twice. It's already included if !_LIBC. (fts_safe_changedir): Add a comment. 2006-11-07 Paul Eggert * m4/longlong.m4 (AC_TYPE_LONG_LONG_INT): Detect bug in Tandem NonStop Kernel (OSS) cc -O circa 2004, reported by Matthew Woehlke. * lib/xalloc.h (XMALLOC, XNMALLOC, XZALLOC, XCALLOC): Move definitions up, to avoid colliding with change below. (static_inline) [HAVE_INLINE]: New macro. (xnmalloc, xnrealloc, x2nrealloc, xcharalloc): Provide extern decls when !HAVE_INLINE. Do not define unless static_inline is defined, either by us or by xmalloc.c. Use static_inline rather than static inline. (XCALLOC): Optimize sizeof(T) = 1 case. * lib/xmalloc.c (static_inline) [!HAVE_INLINE]: New macro. 2006-11-07 Bruno Haible * lib/xalloc.h (XNMALLOC): Restore optimization of sizeof(T) = 1 case. * m4/xalloc.m4 (gl_PREREQ_XALLOC): Require gl_INLINE instead of AC_C_INLINE. * modules/xalloc (Files): Add m4/inline.m4. 2006-11-07 Ralf Wildenhues * README: Fix typo. * doc/gnulib.texi (Miscellaneous Notes): Likewise, rename... (Miscellanous Notes): ...from this. 2006-11-07 Paul Eggert * m4/flexmember.m4 (AC_C_FLEXIBLE_ARRAY_MEMBER): Mention that offsetof should be used instead of sizeof. From Bruno Haible. 2006-11-07 Bruno Haible * lib/w32spawn.h (prepare_spawn): Use XNMALLOC instead of xmalloc. 2006-11-06 Paul Eggert Simplify xmalloc expressions. Add overflow check in xmalloc arguments. * lib/gl_anyavltree_list2.h (create_subtree_with_contents): (gl_tree_create, gl_tree_add_first, gl_tree_add_last): (gl_tree_add_before, gl_tree_add_after): Use XMALLOC instead of xmalloc, and XCALLOC instead of xzalloc. * lib/gl_anyhash_list2.h (hash_resize): Likewise. * lib/gl_anylinked_list2.h (gl_linked_create_empty, gl_linked_create): (gl_linked_add_first, gl_linked_add_last, gl_linked_add_before): (gl_linked_add_after, gl_linked_add_at): Likewise. * lib/gl_anyrbtree_list2.h (create_subtree_with_contents): (gl_tree_create, gl_tree_add_first, gl_tree_add_last): (gl_tree_add_before, gl_tree_add_after): Likewise. * lib/gl_anytree_list2.h (gl_tree_create_empty): Likewise. * lib/gl_anytree_oset.h (gl_tree_create_empty): Likewise. * lib/gl_anytreehash_list1.h (add_to_bucket): Likewise. 2006-11-06 Ralf Wildenhues * lib/gl_oset.h: Use C comment style, not C++ comment style. 2006-11-06 Bruno Haible * m4/inline.m4: New file. * m4/gl_list.m4 (gl_LIST): Require gl_INLINE. * modules/list (Files): Add m4/inline.m4. * modules/oset (Files): Likewise. 2006-11-06 Paul Eggert * lib/idcache.c: Include , for offsetof. (struct userid.name): Change from char * to a flexible array member. All uses changed. * modules/idcache (Depends-on): Add flexmember. * MODULES.html.sh (Core language properties): New module flexmember. * modules/flexmember, m4/flexmember.m4: New files. * lib/xalloc.h (xnmalloc, xnrealloc, x2nrealloc): Now static inline functions that are identical with the old xnmalloc_inline, xnrealloc_inline, x2nrealloc_inline of lib/xmalloc.c. This is so that we can avoid some unnecessary integer multiplications and divisions in the common case where the element size is known at compile time. (XNMALLOC) [HAVE_INLINE]: Remove special case, which is no longer needed. (xnboundedmalloc): Remove. (XMALLOC, XNMALLOC, XZALLOC, XCALLOC): Use lower-case letters for arguments, for consistency with rest of this header. (xcharalloc): Rewrite using XNMALLOC. * lib/xmalloc.c (xnmalloc_inline, xnmalloc, xnrealloc_inline): (xnrealloc, x2nrealloc_inline, x2nrealloc): Remove. The *_inline versions have been moved to lib/xalloc.h and renamed to be the non-*_inline versions.

The latter would fail with a symlink, which is what coreutils' ./bootstrap now creates by default. 2006-10-12 Bruno Haible * lib/inttypes_.h (_LONG_LONG_FORMAT_PREFIX): Don't define for MSVC or mingw. (_PRI64_PREFIX, _PRIu64_PREFIX, _SCN64_PREFIX, _SCNu64_PREFIX): Handle MSVC and mingw explicitly. 2006-10-11 Simon Josefsson Bruno Haible Add support for multiple gnulib-tool invocations in the scope of a single configure.ac file. * gnulib-tool (func_emit_lib_Makefile_am): In the _LIBADD variable, use a private [LT]LIBOBJS variant. Define a _DEPENDENCIES variable with the same contents as the _LIBADD variable. (func_emit_initmacro_start, func_emit_initmacro_end, func_emit_initmacro_done): New functions. (func_import, func_create_testdir): Invoke them. Allow the identifiers gl_LIBOBJS and gl_LTLIBOBJS. 2006-10-11 Bruno Haible * gnulib-tool (GETTEXTPATH, AUTOHEADER, AUTOPOINT): New variables. (func_create_testdir): Don't create po/Makefile.am, don't invoke autoreconf. Instead, invoke autopoint explicitly but move back the *.m4 files from gnulib. 2006-10-11 Bruno Haible * gnulib-tool (func_usage): Make module names after --create-testdir optional. (func_create_testdir): If no module was specified, use nearly all modules. 2006-10-12 Jim Meyering Big performance improvement for fts-based tools that use FTS_NOSTAT. Avoid spurious inode-mismatch problems on non-POSIX file systems. Details: http://article.gmane.org/gmane.comp.lib.gnulib.bugs/7416 * lib/fts_.h (FTS_DEFER_STAT): Define new flag. (FTS_OPTIONMASK): Extend the mask to reflect this addition. * lib/fts.c (DT_IS_KNOWN, DT_MUST_BE): Define. (FTS_NO_STAT_REQUIRED, FTS_STAT_REQUIRED): Define. (fts_set_stat_required): New function. (fts_open): Defer the calls to fts_stat, if possible or requested. Move the code that maps a command-line fts_info value FTS_DOT to FTS_D into fts_stat itself. (fts_read): Perform any required (deferred) fts_stat call. (fts_build): Likewise, for the directory we're about to open and read. In the readdir loop, carefully decide whether each entry will require an eventual call to fts_stat, using dirent.d_type info if available. (fts_stat): Move the test for whether to honor FTS_COMFOLLOW on a command line argument into this function. Update all callers. Map a return value of FTS_DOT to FTS_D for a command line argument. * modules/fts (Depends-on): Add d-type. Alphabetize. Thanks to Miklos Szeredi for his tenacity and for the initial bug report about "find" failing on a FUSE-based file system. * lib/fts.c (fts_open): Use consistent indentation. 2006-10-12 Paul Eggert * m4/extensions.m4 (AC_USE_SYSTEM_EXTENSIONS): Renamed from gl_USE_SYSTEM_EXTENSIONS, to fix a coreutils bootstrap failure reported by Jim Meyering. All uses of cache variables renamed to match Autoconf's. (gl_USE_SYSTEM_EXTENSIONS): New macro, which simply requires the other one. * m4/rename-dest-slash.m4 (gl_FUNC_RENAME_TRAILING_DEST_SLASH): Fix misspelling in diagnostic. 2006-10-11 Paul Eggert * lib/mkdir-p.c (HAVE_FCHMOD): Define to false if not already defined. Problem reported by Matthew Woehlke. * lib/inttypes_.h (_LONG_LONG_FORMAT_PREFIX): New macro. Add support for Tandem NonStop R series. (_PRI64_PREFIX, _PRIu64_PREFIX, _SCN64_PREFIX, _SCNu64_PREFIX): Use new macro. * lib/rename-dest-slash.c: Include stdbool.h but not string.h. (has_trailing_slash): Omit size arg; all callers changed. Omit 'inline', since it doesn't help performance and we'd need to configure it. Don't count //, ///, etc. as having a trailing slash. As a side effect, this removes a C99ism reported by Matthew Woehlke. (rpl_rename_dest_slash): On failure, use rename's errno rather than (in some cases) an incorrect or junk errno. Simplify code by removing need to compute length; this does cause it to make two passes instead of one over the file name, but it's worth it. * m4/extensions.m4 (gl_USE_SYSTEM_EXTENSIONS): Undo previous change, since Autoconf's version may no longer be appropriate now that we are using CVS Autoconf's version. Add support for Tandem. 2006-10-11 Paul Eggert Bruno Haible * lib/allocsa.h (sa_alignment_longlong, sa_alignment_max): Test HAVE_LONG_LONG_INT instead of HAVE_LONG_LONG. * m4/allocsa.m4 (gl_ALLOCSA): Invoke AC_TYPE_LONG_LONG_INT instead of gl_AC_TYPE_LONG_LONG. * lib/printf-args.h (arg_type, argument): Test HAVE_LONG_LONG_INT instead of HAVE_LONG_LONG. * lib/printf-args.c (printf_fetchargs): Likewise. * lib/printf-parse.c (PRINTF_PARSE): Likewise. * lib/vasnprintf.c (VASNPRINTF): Likewise. * m4/vasnprintf.m4 (gl_PREREQ_PRINTF_ARGS, gl_PREREQ_PRINTF_PARSE, gl_PREREQ_VASNPRINTF): Invoke AC_TYPE_LONG_LONG_INT instead of gl_AC_TYPE_LONG_LONG. 2006-10-11 Bruno Haible * m4/longlong.m4: Add comments. * m4/ulonglong.m4: Likewise. 2006-10-10 Bruno Haible Make it possible to #define stpcpy, strdup to aliases. * lib/stpcpy.c (stpcpy) [!_LIBC]: Don't undefine. * lib/strdup.c (strdup) [!_LIBC]: Don't undefine. 2006-10-10 Bruno Haible Make it possible to #define gcd to an alias. * lib/gcd.c: Include config.h. 2006-10-10 Bruno Haible Make it possible to #define c_isascii to an alias. * lib/c-ctype.h: Don't define the macros if NO_C_CTYPE_MACROS is defined. Undefine the macros before defining them, to avoid gcc warnings. * lib/c-ctype.c: Include config.h. Don't undefine the macros; instead, define NO_C_CTYPE_MACROS early. 2006-10-10 Bruno Haible Make it possible to #define set_program_name to an alias. * lib/progname.c: Don't undefine set_program_name; instead, undefine ENABLE_RELOCATABLE early. 2006-10-10 Paul Eggert Port to Tandem NSK OSS, which has 64-bit signed int but at most 32-bit unsigned int. Problem reported by Matthew Woehlke in: http://lists.gnu.org/r/bug-coreutils/2006-10/msg00062.html More generally, don't assume that 64-bit signed int is available if unsigned int is, and vice versa. * lib/inttypes_.h (_PRIu64_PREFIX, _SCNu64_PREFIX): Depend on unsigned symbols, not on their signed counterparts. * lib/stdint_.h (uint64_t, uint_least64_t, uint_fast64_t, uintmax_t): (UINT64_MAX, UINT_LEAST64_MAX, UINT_FAST64_MAX, UINTMAX_MAX): (UINT64_C, UINTMAX_C): Likewise. * lib/strtoimax.c (strtoll): Depend on signed symbols, not their unsigned counterparts. (Have_long_long, Unsigned): New macros. (Int): Renamed from INT. (strtoimax): Use the new macros. * m4/stdint.m4 (gl_STDINT_H): Require AC_TYPE_UNSIGNED_LONG_LONG_INT and substitute HAVE_UNSIGNED_LONG_LONG_INT. * modules/inttypes (inttypes.h): Substitute HAVE_UNSIGNED_LONG_LONG_INT. * modules/stdint (stdint.h): Likewise. (Files): Add m4/ulonglong.m4. 2006-10-10 Bruno Haible Fix a gcc -Wshadow warning. * lib/gl_anyhash_list2.h (hash_resize): Rename local variable 'index' to 'bucket'. * lib/gl_anylinked_list2.h (gl_linked_search_from_to, gl_linked_indexof_from_to): Likewise. * lib/gl_linkedhash_list.c (add_to_bucket, remove_from_bucket): Likewise. * lib/gl_anytreehash_list1.h (add_to_bucket, remove_from_bucket): Likewise. * lib/gl_anytreehash_list2.h (gl_tree_search_from_to): Likewise. Reported by Eric Blake. 2006-10-09 Paul Eggert * lib/filemode.h [HAVE_DECL_STRMODE]: Include unistd.h too, for NetBSD. Problem reported by Bruno Haible. 2006-10-09 Jim Meyering * lib/lchown.c: Include before "stat-macros.h". Patch from Bruno Haible. 2006-10-09 Jim Meyering * lib/fts-cycle.c (leave_dir): When "leaving" a top level directory due to FTS_SKIP, don't copy the parent's uninitialized dev/ino values. Trigger with e.g., mkdir d && valgrind ./chmod u+rwx d d 2006-10-08 Paul Eggert Don't include twice; this doesn't work in some cases, e.g., when config.h has "#define intmax_t long long int" and we include , , in that order. Problem reported by Matthew Woehlke in: http://lists.gnu.org/r/bug-coreutils/2006-10/msg00073.html * lib/fprintftime.c: Don't include config.h or fprintftime.h. * lib/fts-cycle.c: Don't include config.h. * lib/strftime.c: Include fprintftime.h if FPRINTFTIME is defined. * lib/xstrtoimax.c: Remove copyright notice since it's short tnow. Don't include config.h or xstrtol.h. Define STRTOL_T_MINIMUM and STRTOL_T_MAXIMUM unconditionally, since we now assume gnulib inttypes.h. * lib/xstrtoumax.c: Likewise. * lib/xstrtol.c: Include config.h and xstrtol.h after defining __strtol and the like, so that this module is more like its siblings. (STRTOL_T_MINIMUM, STRTOL_T_MAXIMUM) [! defined STRTOL_T_MINIMUM]: Remove; no longer needed now that we assume gnulib inttypes.h. 2006-10-08 Bruno Haible * doc/gnulib-tool.texi: Emphasize the drawbacks of the --symlink option. 2006-10-07 Jim Meyering * modules/inttypes (inttypes.h): Revert what seems to have been an inadvertent part of today's change: use "|", not "/" in the substitution for the "/"-containing string, $(ABSOLUTE_INTTYPES_H). 2006-10-07 Bruno Haible * modules/sublist: New file. 2006-10-07 Bruno Haible * modules/alloca-opt (alloca.h): Add a "DO NOT EDIT" comment. * modules/argz (argz.h): Likewise. * modules/arpa_inet (arpa/inet.h): Likewise. * modules/byteswap (byteswap.h): Likewise. * modules/configmake (configmake.h): Likewise. * modules/fcntl (fcntl.h): Likewise. * modules/fnmatch (fnmatch.h): Likewise. * modules/getopt (getopt.h): Likewise. * modules/glob (glob.h): Likewise. * modules/inttypes (inttypes.h): Likewise. * modules/netinet_in (netinet/in.h): Likewise. * modules/poll (poll.h): Likewise. * modules/stdbool (stdbool.h): Likewise. * modules/stdint (stdint.h): Likewise. * modules/sys_select (sys/select.h): Likewise. * modules/sys_socket (sys/socket.h): Likewise. * modules/sys_stat (sys/stat.h): Likewise. * modules/sysexits (sysexits.h): Likewise. * modules/unistd (unistd.h): Likewise. * gnulib-tool (func_emit_lib_Makefile_am, func_emit_tests_Makefile_am): Add a "DO NOT EDIT" comment to the generated file.

Instead, include dirchownmod.h and mkancesdirs.h. (make_dir_parents): New args MAKE_ANCESTOR, OPTIONS, ANNOUNCE, MODE_BITS. Remove options VERBOSE_FMT_STRING, CWD_ERRNO. All callers changed. Revamp internals significantly, by not attempting to create directories that are temporarily more permissive than the final results.

Baushke. 2006-07-04 Paul Eggert * m4/absolute-header.m4 (gl_ABSOLUTE_HEADER): Prepend three slashes to the absolute name, not just one, to bypass Sun C 5.8's "warning: #include of /usr/include/... may be non-portable". 2006-07-04 Eric Blake * modules/dirname-tests: New test module. * tests/test-dirname.c: New file, replacing dirname.c TEST_DIRNAME section that was recently deleted. 2006-07-04 Bruno Haible Assume ANSI C header files and functions. * lib/mbswidth.c (IN_CTYPE_DOMAIN, ISPRINT, ISCNTRL): Remove macros.

This is to keep the terminology clean; POSIX talks about "absolute pathnames", not "full pathnames", but the GNU Coding Standards say to use "path" for something else; so use "absolute" to keep both sides happy. (gl_ABSOLUTE_HEADER): Renamed from gl_FULL_HEADER_PATH. Set gl_absolute_header, not gl_full_header_path. Set gl_cv_absolute_
, not gl_full_path_

Require gl_USE_SYSTEM_EXTENSIONS, not gl_C_STRTOD, since we don't want to require the building of c-strtod.o. * m4/lib-check.m4 (cu_LIB_CHECK): Remove SEQ_LIBM, since seq no longer needs -lm directly. * m4/xstrtod.m4 (gl_XSTRTOLD): New macro. 2006-06-19 Paul Eggert * m4/lib-ignore.m4 (gl_IGNORE_UNUSED_LIBRARIES): Prefer binutils's --as-needed option if available. Problem reported by Albert Chin in . However, use -Wl,--as-needed, not bare --as-needed, since HP-UX 11.11 cc merely issues a bunch of annoying warnings for --as-needed (this problem was reported by Bob Proulx). Also, try linking with -lm to detect a bug in binutils 2.16 (this problem was reported by Ralf Wildenhues). 2006-06-18 Jim Meyering Test for a bug that causes glibc's getcwd to suffer a failed assertion. * m4/getcwd-abort-bug.m4 (gl_FUNC_GETCWD_ABORT_BUG): New file and macro. * m4/getcwd.m4 (gl_FUNC_GETCWD): If we detect support for getcwd_null, also check for glibc-2.4's abort-inducing bug. * m4/getcwd-path-max.m4 (gl_FUNC_GETCWD_PATH_MAX): Fix typo. Low-probability clean-up should be to use rmdir to get rid of the just-created directory, not unlink. * m4/ftruncate.m4 (gl_FUNC_FTRUNCATE): If ftruncate is missing, make configure fail, and request a bug report to inform us about it. Add a comment that, barring reports to the contrary, in 2007 we'll assume ftruncate is universally available. 2006-04-17 Paul Eggert * m4/filemode.m4 (gl_FILEMODE): Check for strmode declaration. 2006-03-12 Jim Meyering * m4/chdir-safer.m4 (gl_CHDIR_SAFER): Add same-inode.h to the list. * m4/cycle-check.m4 (gl_CYCLE_CHECK): Likewise. * m4/same.m4 (gl_SAME): Likewise. * m4/root-dev-ino.m4 (gl_ROOT_DEV_INO): Likewise. 2006-03-11 Eric Blake * m4/double-slash-root.m4: New file, provides gl_DOUBLE_SLASH_ROOT. * m4/dirname.m4 (gl_DIRNAME): Use gl_DOUBLE_SLASH_ROOT. * m4/dos.m4 (FILE_SYSTEM_PREFIX_LEN): Move from here to dirname.h. (FILE_SYSTEM_DRIVE_PREFIX_CAN_BE_RELATIVE): New define. 2006-07-03 Paul Eggert * lib/stdint_.h: Include after @FULL_PATH_STDINT_H@, for MacOS X 10.4.6. Don't mention . Problems reported by Mark D. Baushke, one in . Merge from coreutils. * lib/.cppi-disable: Add stdint_.h. * lib/.cvsignore: Add stdint.h. 2006-06-30 Paul Eggert * lib/xstrtod.c (XSTRTOD, DOUBLE): New macros, so that we can support both double and long double versions. (XSTRTOD): Renamed from xstrtod. Use DOUBLE internally. * lib/xstrtold.c: New file. * lib/xstrtod.h (xstrtold): New decl. 2006-05-22 Paul Eggert * lib/filemode.c (setst): Remove. (strmode): Rewrite to avoid setst. This makes the code shorter, (arguably) clearer, and the generated code is a bit smaller on my Debian GNU/Linux stable x86 host. 2006-04-17 Paul Eggert * lib/filemode.c: Include "filemode.h" first, to test the interface. Assume that filemode.h includes sys/types.h and sys/stat.h. (HAVE_ST_DM_MODE): New macro, moved here from ls.c. (ftypelet): Reorder to put common cases first, for efficiency. Add 'P', 'w'. Remove 'M', since it's now the caller's responsibility to do 'M'. (strmode): Renamed from mode_string, and now stores 12 bytes instead of 10, for compatibility with FreeBSD. All callers changed. (filemodestring): Now stores 12 bytes instead of 10, and sets file types that can't be deduced solely from st_mode. First arg is now a const pointer. * lib/filemode.h (HAVE_DECL_STRMODE): Include for strmode. (strmode): Renamed from mode_string. (filemodestring): New decl. * lib/stat-macros.h: Don't undef S_ISDOOR, since it's never buggy. (S_ISDOOR): Don't bother with S_IFDOOR, since that code is never needed. (S_ISPORT, S_ISWHT): New macros, if not already defined. 2006-04-12 Paul Eggert * lib/fsusage.c: Don't include or , since fsusage.h now does that. Include fsusage.h first, to test interface. Prefer statvfs if it works, since it's blessed by POSIX. Attempt at most one method (the old code could have generated decls that didn't conform to C89, not that this was ever exercised). * lib/fsusage.h: Include and if they exist. 2006-03-19 Jim Meyering Work even in a chroot where d_ino values for entries in "/" don't match the stat.st_ino values for the same names. * lib/getcwd.c (__getcwd): When no d_ino value matches the target inode number, iterate through all entries again, using lstat instead. Reported by Kenshi Muto in http://bugs.debian.org/355810, and by Zouhir Hafidi in https://bugzilla.redhat.com/bugzilla/190656. * lib/getcwd.c (__getcwd): Clarify a comment. Use memcpy in place of a call to strcpy. 2006-03-12 Jim Meyering * lib/fts-cycle.c (leave_dir): If cycle-check's saved dev-ino pair matches that of the current directory (which we're about to chdir ".." out of), then save the dev-ino of the parent, instead. * lib/same-inode.h (SAME_INODE): New file/macro. * lib/chdir-safer.c (SAME_INODE): Remove definition. Include "same-inode.h", instead. * lib/same.c: Likewise. * lib/cycle-check.h: Include "same-inode.h". (CYCLE_CHECK_REFLECT_CHDIR_UP): Define. * lib/cycle-check.c (SAME_INODE): Remove definition. * lib/root-dev-ino.h: Include "same-inode.h". 2006-03-11 Eric Blake * lib/same.c (same_name): s/base_name/last_component/ * lib/backupfile.c (check_extension, numbered_backup): Likewise. * lib/filenamecat.c (file_name_concat): Likewise. 2006-03-11 Eric Blake , Paul Eggert * lib/dirname.h (FILE_SYSTEM_PREFIX_LEN): Move here from dos.m4. [FILE_SYSTEM_ACCEPTS_DRIVE_LETTER_PREFIX]: Don't treat 1: as a drive prefix. (IS_ABSOLUTE_FILE_NAME): Treat all drive letters as absolute on platforms like cygwin with FILE_SYSTEM_DRIVE_PREFIX_IS_ABSOLUTE. (last_component): New method. * lib/dirname.c (dir_len): Determine when drive letters need a subsequent slash. Preserve // when it is special. (dir_name): Don't append dot when drive letter is absolute. [TEST_DIRNAME]: Move into a full-blown gnulib test. * lib/basename.c (base_name): New semantics - malloc the result. Preserve // when it is special. Preserve relative files that look like drive letters. (base_len): Preserve // when it is special. (last_component): New method, similar to old base_name semantics. * lib/stripslash.c (strip_trailing_slashes): Use last_component, not base_name. Strip redundant slashes from ///. 2006-07-03 Jim Meyering * lib/cycle-check.h (CYCLE_CHECK_REFLECT_CHDIR_UP): Abort if this macro is used before the first cycle_check call. 2006-07-03 Eric Blake * modules/dirname (Depends-on): Add xstrndup. 2006-07-02 Paul Eggert * m4/stdint.m4 (gl_STDINT_H): Use more-mnemonic identifiers for test cases, so that config.log is a bit easier to follow. 2006-07-02 Paul Eggert * lib/stdint_.h (intmax_t, uintmax_t): Prefer long to long long if both are 64 bits, since this seems to be the tradition, and this prevents gcc -Wformat from warning about usages with PRIuMAX. If we ever run into a host that prefers long long to long in this case, we'll need another configure-time test. Problem reported by Jim Meyering. 2006-07-02 Eric Blake * m4/wcwidth.m4 (gl_FUNC_WCWIDTH): Simplify by using AC_CHECK_DECLS. 2006-07-01 Paul Eggert * modules/inttypes (Depends-on): No longer depends on stdint. * modules/stdint (Description): Say more about assumptions. Say that the fast types might differ. Say macros are used. (Files): Remove m4/size_max.m4, m4/wchar_t.m4. Add m4/longlong.m4. (Makefile.am): Revise list of substituted symbols to match new stdint.m4. * modules/stdint-tests (Files): Add m4/wchar_t.m4, m4/wint_t.m4. (configure.ac): Add gt_TYPE_WCHAR_T, gt_TYPE_WINT_T. * tests/test-stdint.c (verify_same_types) [! (__GNUC__ >= 2 && DO_PEDANTIC)]: Put in a decl, so that the code conforms to C99/C89. Test for WCHAR_MIN and WCHAR_MAX only if HAVE_WCHAR_T. Test for WINT_MIN and WINT_MAX only if HAVE_WINT_T. 2006-07-01 Paul Eggert * m4/longlong.m4 (AC_TYPE_LONG_LONG_INT): Backport from Autoconf 2.60, but fix a bug, by requiring at least 64 bits. * m4/ulonglong.m4 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise. * m4/longlong.m4 (gl_AC_TYPE_LONG_LONG): Now just call AC_TYPE_LONG_LONG_INT. This macro is obsolete and will go soon. * m4/ulonglong.m4 (gl_AC_TYPE_UNSIGNED_LONG_LONG): Likewise. * m4/stdint.m4 (gl_STDINT_H): Rewrite to accommodate stdint_.h changes. Make 2.59 a prerequisite. Check and substitute for HAVE_LONG_LONG_INT. Rely on Autoconf to check for stdint.h and inttypes.h. Do not use special include files; just use the defaults. Check for sys/inttypes.h and sys/bitypes.h in the usual way now. Remove no-longer-needed tests for HAVE_LONG_64BIT, HAVE_LONG_LONG_64BIT, int8_t, int16_t, int32_t, int64_t, uint8_t, uint16_t, uint32_t uint64_t, int_least8_t, int_least16_t, int_least32_t, int_least64_t, uint_least8_t, uint_least16_t, uint_least32_t, uint_least64_t, int_fast8_t, int_fast16_t, int_fast32_t, int_fast64_t, uint_fast8_t uint_fast16_t, uint_fast32_t, uint_fast64_t, intptr_t, uintptr_t, intmax_t, uintmax_t, INT8_MIN, INT8_MAX, UINT8_MAX, INT16_MIN, INT16_MAX, UINT16_MAX, INT32_MIN, INT32_MAX, UINT32_MAX, INT64_MIN, INT64_MAX, UINT64_MAX, INT_LEAST8_MIN, INT_LEAST8_MAX, UINT_LEAST8_MAX, INT_LEAST16_MIN, INT_LEAST16_MAX, UINT_LEAST16_MAX, INT_LEAST32_MIN, INT_LEAST32_MAX, UINT_LEAST32_MAX, INT_LEAST64_MIN, INT_LEAST64_MAX, UINT_LEAST64_MAX, INT_FAST8_MIN, INT_FAST8_MAX, UINT_FAST8_MAX, INT_FAST16_MIN, INT_FAST16_MAX, UINT_FAST16_MAX, INT_FAST32_MIN, INT_FAST32_MAX, UINT_FAST32_MAX, INT_FAST64_MIN, INT_FAST64_MAX, UINT_FAST64_MAX, INTPTR_MIN, INTPTR_MAX, UINTPTR_MAX, INTMAX_MIN, INTMAX_MAX, UINTMAX_MAX, PTRDIFF_MIN, PTRDIFF_MAX, SIG_ATOMIC_MIN, SIG_ATOMIC_MAX, SIZE_MAX, WCHAR_MIN, WCHAR_MAX, WINT_MIN, WINT_MAX. Check for C99 conformance more strictly, by detecting bugs in glibc 2.4, Solaris 10, and OpenBSD 3.9. On the other hand do not check for things that C99 does not require, e.g., int8_t. If a test isn't needed unless isn't working, and is unlikely to be needed for any other reason, then don't do it unless isn't working. Do not check for ptrdiff_t or size_t, since we assume C89 freestanding at least. Do not check for sig_atomic_t, wchar_t, or wint_t, since the code now does the right thing even if the types are not defined. Instead use: (gl_STDINT_TYPE_PROPERTIES): New macro. (gl_HEADER_STDINT_H, gl_HEADER_INTTYPES_H): Remove. Don't bother testing whether clashes, as Autoconf does this for us now. All uses removed. (gl_STDINT_CHECK_TYPES, gl_STDINT_MISSING_BOUND): (gl_STDINT_MISSING_BOUNDS, gl_STDINT_MISSING_BOUNDS2): (gl_CHECK_TYPE_SAME): Remove; no longer needed. (gl_STDINT_BITSIZEOF): Don't bother to check whether the type exists, since we'll return 0 anyway in that case. (gl_INTEGER_TYPE_SUFFIX, gl_STDINT_INCLUDES): New macros. 2006-07-01 Paul Eggert * lib/stdint_.h (_GL_STDINT_H): Renamed from _STDINT_H, to avoid possible collision with system files. (, , ) [defined __cplusplus && ! defined __STDC_CONSTANT_MACROS)]: Do not include, since we don't need WCHAR_MIN and WCHAR_MAX in this case. (): Do not include; no longer needed. (): Include if @HAVE_SYS_TYPES_H@, not if (defined(__OpenBSD__) || defined(__bsdi__) || defined(__sgi)). (): Include if @HAVE_SYS_INTTYPES_H@ && !@HAVE_INTTYPES_H@, not if (defined(__FreeBSD__) && (__FreeBSD__ >= 3) && (__FreeBSD__ <= 4)). (__STDINT_H__) [@HAVE_STDINT_H@ && defined __sgi && ! defined __c99]: Define, to work around IRIX incompatibility. (@FULL_PATH_STDINT_H@) [!(defined(__sgi) && @HAVE_INTTYPES_H@ && !defined(__c99))]: Include in this case too, since it's harmless now. () [@HAVE_INTTYPES_H@]: Include, since it's no longer dangerous to do so. (@FULL_PATH_INTTYPES_H@) [(defined(__hpux) || defined(_AIX)) && @HAVE_INTTYPES_H@]: Do not include, since we now include . (_STDINT_MIN, _STDINT_MAX): New macros. (int8_t, uint8_t, int16_t, uint16_t, int32_t, uint32_t, int64_t): (uint64_t, int_least8_t, uint_least8_t, int_least16_t): (uint_least16_t, int_least32_t, uint_least32_t, int_least64_t): (uint_least64_t, int_fast8_t, uint_fast8_t, int_fast16_t): (uint_fast16_t, int_fast32_t, uint_fast32_t, int_fast64_t): (uint_fast64_t, intptr_t, uintptr_t, intmax_t, uintmax_t): Now macros, not typedefs; this simplifies things quite a bit. Use long int for all types narrower than int64_t. (intmax_t, uintmax_t, INTMAX_C, UINTMAX_C): Define in terms of long long int or int64_t or long int, not int64_t or int32_t. This saves some compile-time testing. (INT8_MIN, INT8_MAX, UINT8_MAX, INT16_MIN, INT16_MAX, UINT16_MAX): (INT32_MIN, INT32_MAX, UINT32_MAX, INT64_MIN, INT64_MAX): (UINT64_MAX, INT_LEAST8_MIN, INT_LEAST8_MAX, UINT_LEAST8_MAX): (INT_LEAST16_MIN, INT_LEAST16_MAX, UINT_LEAST16_MAX): (INT_LEAST32_MIN, INT_LEAST32_MAX, UINT_LEAST32_MAX): (INT_LEAST64_MIN, INT_LEAST64_MAX, UINT_LEAST64_MAX, INT_FAST8_MIN): (INT_FAST8_MAX, UINT_FAST8_MAX, INT_FAST16_MIN, INT_FAST16_MAX): (UINT_FAST16_MAX, INT_FAST32_MIN, INT_FAST32_MAX, UINT_FAST32_MAX): (INT_FAST64_MIN, INT_FAST64_MAX, UINT_FAST64_MAX, INTPTR_MIN): (INTPTR_MAX, UINTPTR_MAX, INTMAX_MIN, INTMAX_MAX, UINTMAX_MAX): (PTRDIFF_MIN, PTRDIFF_MAX, SIG_ATOMIC_MIN, SIG_ATOMIC_MAX): (SIZE_MAX, WCHAR_MIN, WCHAR_MAX, WINT_MIN, WINT_MAX): undef any previous version and define our own version, for simplicity and consistency with the new macros for types. (PTRDIFF_MIN, PTRDIFF_MAX, SIG_ATOMIC_MIN, SIG_ATOMIC_MAX): (SIZE_MAX, WCHAR_MIN, WCHAR_MAX, WINT_MIN, WINT_MAX): Simplify definitions by using _STDINT_MIN and _STDINT_MAX where appropriate. Rely on new symbols @PTRDIFF_T_SUFFIX@, @SIG_ATOMIC_T_SUFFIX@, @SIZE_T_SUFFIX@, @WCHAR_T_SUFFIX@, @WINT_T_SUFFIX@ to keep things simple here. (UINT8_C, UINT16_C, UINT32_C, INT64_C, UINT64_C): Simplify by assuming typical 8/16/32/64 host, since we're already doing that elsewhere anyway. Use (LONG_MAX >> 31 >> 31 == 1) rather than @HAVE_LONG_64BIT@, and assume long long int is 64 bits if available. This speeds up 'configure'. 2006-07-01 Eric Blake * m4/stdarg.m4 (gl_STDARG_H): Use proper AH_VERBATIM. Reported by Andreas Buening. 2006-07-01 Eric Blake * m4/stdarg.m4 (gl_STDARG_H): Properly parenthesize gl_va_copy. 2006-06-30 Jim Hyslop (tiny change) * lib/getaddrinfo.c: fixed typo 2006-06-29 Jim Meyering * modules/strftime (Maintainer): Add my name, since with the FPRINTFTIME changes strftime.c has forked from glibc. 2006-06-29 Eric Blake * m4/sys_stat_h.m4 (gl_HEADER_SYS_STAT_H): Use AC_C_INLINE. 2006-06-29 Eric Blake * m4/sys_stat_h.m4 (gl_HEADER_SYS_STAT_H): New file. 2006-06-29 Eric Blake * lib/stat_.h: New file. 2006-06-29 Eric Blake * lib/stat_.h (rpl_mkdir): Declare inline, to avoid warnings about unused static function. 2006-06-29 Eric Blake * doc/functions.texi (Function Portability): Document missing lstat on mingw. 2006-06-29 Eric Blake * MODULES.html.sh: Add sys_stat. * modules/sys_stat: New module. * modules/mkstemp (Depends-on): Add sys_stat. 2006-06-29 Derek R.

Call WSAStartup on _WIN32. * modules/getaddrinfo (Depends-on): Add inet_ntop, needed by getnameinfo. 2006-06-28 Simon Josefsson * m4/getaddrinfo.m4: Look for getnameinfo prototypes too. 2006-06-28 Simon Josefsson * lib/getaddrinfo.c: Try to load ws2_32.dll on Windows, to find the functions there. It will succeed on Windows XP, but on Windows 2000 and (presumably) earlier, it will fail, and use the internal re-implementation. (use_win32_p): New function. (getaddrinfo): Use strtoul on servname, to support numeric ports. Support AI_NUMERICSERV to disable getservbyname. (getnameinfo): New function, only supports NI_NUMERICHOST|NI_NUMERICSERV for now. * lib/getaddrinfo.h: Test and check for AI_* flags separately, MinGW only have some of them. Add AI_NUMERICSERV. Add prototype for getnameinfo. 2006-06-28 Eric Blake * modules/wcwidth: New file. * modules/mbchar (Depends-on): Add wcwidth. * modules/mbswidth (Depends-on): Add wcwidth. * MODULES.html.sh: Add wcwidth. 2006-06-28 Eric Blake * m4/mbswidth.m4 (gl_MBSDWIDTH): Move wcwidth from here... * m4/wcwidth.m4 (gl_FUNC_WCWIDTH): ...to this new file. 2006-06-28 Eric Blake * lib/xvasprintf.h: Fix comments. 2006-06-28 Eric Blake * lib/mbchar.h (wcwidth): Include wcwidth.h. * lib/mbswidth.c (wcwidth): Move from here... * lib/wcwidth.h: ...to this new file. 2006-06-28 Derek R.

Settle for the traditional glibc names. Even if glibc is changed to conform to POSIX, the traditional names will be available anyway, since regex depends on the extensions module.

Instead, check that regoff_t is as least as wide as ptrdiff_t. Don't define _REGEX_WIDE_OFFSETS unless using the included regex, so that our regex.h stays compatible with the installed regex.

(License): Change from GPL to LGPL, since this is now simply a replacement for a libc function. 2006-02-14 Jim Meyering Sync from coreutils. Eliminate the unwelcome (albeit unlikely) possibility of xmalloc failure on deficient systems, and simplify gnulib lgpl dependencies. * lib/lstat.c (rpl_lstat): Rewrite to use stat() in place of the xmalloc/lstat combination. Based on a patch from Bruno Haible. * lib/xalloc-die.c: Remove unused definition of N_. 2006-02-14 Jim Meyering Sync from coreutils. * m4/ls-mntd-fs.m4 (AC_FUNC_GETMNTENT): Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need not double-quote uses of that variable, to accommodate the rare case in which getmntent is available in none of the libraries checked. This happens at least on FreeBSD 5.0. 2006-02-13 Simon Josefsson * gnulib-tool (Usage): Fix --import, from karl@freefriends.org (Karl Berry). 2006-02-13 Sergey Poznyakoff * lib/argp-fmtstream.c: Restore another bugfix lost on 2005-12-12 2006-02-07 Sergey Poznyakoff * lib/argp-namefrob.h: Restore changes accidentally lost during the "autoupdate" on 2005-12-12. 2006-02-07 Paul Eggert * modules/closeout (Depends-on): Remove atexit. 2006-02-07 Paul Eggert * lib/closeout.c (close_stdout): Don't assume 'bool' converts nonzero ints to 0 or 1, as this isn't true for the stdbool.h substitute. 2006-02-05 Paul Eggert * m4/extensions.m4 (gl_USE_SYSTEM_EXTENSIONS): Don't #define __EXTENSIONS__ if this causes compilation to fail. Problem reported by Nelson H. F. Beebe with Solaris 10 and Sun C 5.7 c89 -D_XOPEN_SOURCE -D_XOPEN_SOURCE_EXTENDED. 2006-01-27 Paul Eggert * lib/fnmatch.c (L_): Renamed from L, to work around a bug in Mac OS X 10.3.9 with GCC 3 reported by Claudio Fontana in . All uses changed. 2006-01-26 Simon Josefsson * lib/socket_.h: Set WINVER to 0x0501, to make sure getaddrinfo prototype is visible on mingw32. * lib/getaddrinfo.h: Define EAI_ADDRFAMILY and EAI_SYSTEM if not set, for mingw32. * lib/gai_strerror.c, getaddrinfo.h: Protect netdb.h #include (for mingw32). 2006-01-26 Paul Eggert * lib/fts.c (diropen): Open with O_NOCTTY | O_NONBLOCK too. Don't attempt to open for write; this always fails, at least on POSIX hosts. This reinstates the 2006-01-09 change, which was inadvertently removed. 2006-01-26 Bruno Haible * gnulib-tool (func_import): Use "trap 'exit $?' instead of "trap :". Reported by Paul Eggert. 2006-01-26 Bruno Haible Paul Eggert * lib/stdbool_.h (_Bool) [(! (defined __cplusplus || defined __BEOS__) && !defined __GNUC__ && !(defined __HP_cc || defined __xlc__ || (defined __SUNPRO_C && (__SUNPRO_C < 0x550 || __STDC__ == 1)) || defined __sgi))]: #define to signed char in these cases too; this simplifies the code (so that we don't have to worry about HP-UX, AIX, SunPRO, etc., separately) and makes it more conservative. 2006-01-25 Simon Josefsson * m4/getaddrinfo.m4: Look for getaddrinfo inside ws2tcip.h and -lws2_32. Protect sys/socket.h and netdb.h #include's. Include ws2tcpip.h with WINVER=0x0501. All for mingw32. 2006-01-25 Sergey Poznyakoff * lib/argp-namefrob.h: Bugfix. Remove stray # 2006-01-25 Paul Eggert * m4/stdbool.m4 (AC_HEADER_STDBOOL): Check for xlc bug if __GCC__ too, so that we test the test. Check for yet another HP-UX cc bug involving *bool |= bool. 2006-01-25 Karl Berry * config/srclist.txt (vasnprintf.c): sync lost. 2006-01-25 Jim Meyering Sync from the stable (b5) branch of coreutils: * lib/fts.c (fts_children): Don't let close() clobber errno from failed fchdir(). * lib/fts.c (fts_stat): When following a symlink-to-directory, don't necessarily interpret stat-fails+lstat-succeeds as indicating a dangling symlink. That can also happen at least for ELOOP. The fix: return FTS_SLNONE only when the stat errno is ENOENT. FYI, this bug predates the inclusion of fts.c in coreutils. * lib/fts.c (fts_open): Put new maxarglen declaration and uses in their own block, so pre-c99 compilers don't object. Avoid the double-free (first in fts_read, second in fts_close) that would occur when an `active' directory is made inaccessible (e.g., via chmod a-x) during a traversal. * lib/fts.c (fts_read): After a failed fchdir, update sp->fts_cur before returning. Reproduce this failure by mkdir -p a/b; cd a; chmod a-x . b Reported by Stavros Passas. 2006-01-25 Jim Meyering * lib/fileblocks.c: Remove more useless parentheses. * lib/readutmp.h: Likewise. 2006-01-25 Bruno Haible * lib/stdbool_.h (_Bool) [IRIX cc]: Define as 'signed char', to avoid warnings.

Baushke . 2006-01-23 Ulrich Drepper These changes imported from libc. * lib/getopt.c: Use __fxprintf instead of inline stream orientation test and two separate function calls. * lib/strndup.c (__strndup): Add libc_hidden_def. 2006-01-23 Simon Josefsson * modules/lock-tests: Use check_PROGRAMS instead of noinst_PROGRAMS. Remove the test_*_SOURCES variable: automake infers it by default. * modules/tls-tests: Likewise. 2006-01-23 Paul Eggert Work around porting bugs reported by Dieter in . * lib/getopt.c (_NOPROTO): Remove; no longer needed. Include and in all environments; it's safe now. Include "getopt.h" first, to check interface. (getenv): Declare only if defined HAVE_DECL_GETENV && !HAVE_DECL_GETENV. * lib/strndup.c [!_LIBC]: Include "strndup.h" to get prototype. (__strndup): Revert to K&R-style function dfns, the glibc style. * lib/strnlen.c: Don't claim it's taken from glibc; it's not. (strnlen, __strnlen): Remove #defines and #undefs; not needed. Include strnlen.h first, to get prototype properly. (strnlen): Renamed from __strnlen. Remove weak alias. 2006-01-23 Paul Eggert * m4/getopt.m4 (gl_PREREQ_GETOPT): Check for getenv decl. 2006-01-23 Paul Eggert * config/srclist.txt: Adjust to reflect glibc reorganization. This affects only comments. 2006-01-22 Ralf Wildenhues (tiny change) * gnulib-tool, build-aux/csharpcomp.sh.in: Do not pass `-q' to mktemp.

(dev_from_mount_options) [defined MOUNTED_GETMNTENT1 || defined MOUNTED_GETMNTENT2]: New function. It no longer assumes "dev=" has the System V meaning on Linux (since it doesn't). It also parses "dev=" more carefully. (read_file_system_list) [defined MOUNTED_GETMNTENT1 || defined MOUNTED_GETMNTENT2]: Use it. MOUNTED_GETMNTENT2 is new here; the code didn't used to look for dev= in that case. * lib/posixtm.h (PDS_PRE_2000): New macro. * lib/posixtm.c (year): Arg is now syntax_bits rather than allow_century.

(openat): Renamed from rpl_openat; no need for rpl_openat since openat.h renames openat for us. Replace most of the body with a call to openat_permissive, to avoid duplicate code. Port to (probably hypothetical) environments were mode_t is wider than int. (openat_permissive): Require mode arg, so that we can check types better. Put it just after flags. Change cwd failure indicator from pointer-to-bool to pointer-to-errno-value. All callers changed. Invoke openat_save_fail and/or openat_restore_fail if cwd_errno is null, so that openat can call us. (openat_permissive, fdopendir, fstatat, unlinkat): Simplify errno handling to avoid some duplicate code, as it's OK to set errno on success. * lib/openat.h: Revamp code so that function macros depend on __OPENAT_PREFIX only, not also on AT_FDCWD. (openat_ro): Remove. Caller changed to use openat_permissive. (openat_permissive): Now a macro, if not a function. (openat_restore_fail, openat_save_fail): Now always functions, since mkdirat needs them even if __OPENAT_PREFIX is defined. * lib/openat-priv.h: New file, defining macros used by mkdirat.c and openat.c. * lib/mkdirat.c: Include openat-priv.h.

Include , , "alloca.h" and "intprops.h". (rpl_openat): Emulate by trying to open /proc/self/fd/%d/%s, before falling back on save_cwd and restore_cwd. (fdopendir, fstatat, unlinkat): Likewise. * lib/openat.c (fstatat, unlinkat): Perform the syscall directly, skipping the save_cwd...restore_cwd overhead, if FILE is absolute. * lib/openat.c (rpl_openat): Use the promoted type (int), not mode_t, as second argument to va_arg.

Remove HAVE_SYS_SOCKET_H test too, to see if any systems lack sys/socket.h; mingw32 is known to lack it, but we don't support it yet anyway. Also remove HAVE_NETDB_H test, for same reasons. 2005-10-05 Simon Josefsson * config/srclist.txt: Add glibc bug 1423 for md5.h. 2005-10-05 Paul Eggert * m4/getaddrinfo.m4 (gl_PREREQ_GETADDRINFO): Don't check for sys/socket.h, netdb.h, sys/types.h; the checks areno longer needed, since the source code now assumes these .h files. 2005-10-05 Derek Price * lib/getdelim.c (SIZE_MAX): New macro, if not already defined. 2005-10-05 Bruno Haible * modules/stdint (License): Change to LGPL. 2005-10-04 Simon Josefsson * lib/getaddrinfo.h: Move sys/types.h include first, reported by "Mark D.

Also, don't bother returning ENOSYS if settimeofday or stime fails; just let them return whatever errno they want to return. * lib/utimens.c: Include unistd.h, for dup2. (futimens): Fix typo: HAVE_FUTIMESAT was misspelled in an #if. (futimens) [! HAVE_FUTIMESAT]: If !file, set errno before returning -1. 2005-10-02 Jim Meyering Sync from coreutils. * m4/utimes.m4 (gl_FUNC_UTIMES): Detect the version of utimes from glibc-2.2.5 that fails for read-only files. 2005-10-02 Jim Meyering Sync from coreutils. * lib/fts-cycle.c [HAVE_CONFIG_H]: Include . * lib/openat-die.c: Use `#ifdef HAVE_CONFIG_H', not `#if HAVE_CONFIG_H'. * lib/openat.c (fdopendir): Do not define if HAVE_FDOPENDIR. Remove AT_FDCWD test. Do not consume the fd unless successful. * lib/openat.h (fdopendir): Do not define if HAVE_FDOPENDIR. * lib/settime.c (settime): Move the HAVE_STIME block `up' into an #elif block, so that we don't even try to compile it if settimeofday is available. This works around a compilation failure on OSF1 V5.1, due to stime requiring a `long int*' while tv_sec is `int'. 2005-10-02 Alfred M. Szmidt Sync from coreutils. * m4/chdir-long.m4 (gl_FUNC_CHDIR_LONG): Compare $gl_have_path... against `yes', rather than just testing for nonempty. 2005-10-01 Simon Josefsson * m4/getaddrinfo.m4: Include sys/types.h for sys/socket.h, on FreeBSD and Darwin. * m4/getaddrinfo.m4: Use AC_GNU_SOURCE, GNU only declare getaddrinfo as an (POSIX) extension. Check for sys/types.h, sys/socket.h, and netdb.h too, needed by getaddrinfo.h. Check if getaddrinfo, freeaddrinfo and gai_strerror are declared by the POSIX headers. Check if struct addrinfo is declared. 2005-10-01 Simon Josefsson * lib/getaddrinfo.h: Protect #include's of sys/socket.h and netdb.h. Only define struct addrinfo if !HAVE_STRUCT_ADDRINFO. Protect AI_* and EAI_* definitions. Protect function declarations. 2005-10-01 Jim Meyering Sync from coreutils. * m4/getaddrinfo.m4 (gl_GETADDRINFO): Look for getservbyname in these libraries [inet nsl socket xnet]. Nelson Beebe reported that with native cc on Solaris 7, getaddrinfo.c requires -lsocket. * m4/getaddrinfo.m4 (gl_GETADDRINFO): Check for gethostbyname in the inet and nsl libraries. Required on Solaris 5.7. 2005-10-01 Jim Meyering Sync from coreutils. * m4/getaddrinfo.m4 (gl_GETADDRINFO): Check for gethostbyname in the inet and nsl libraries. Required on Solaris 5.7. 2005-10-01 Eric Blake (tiny change) * lib/getdelim.c (getdelim): Remove unused variables. 2005-09-29 Paul Eggert * lib/xtime.h (XTIME_PRECISION): Now of type int, not long long int, so that the code works even with ancient cpp. Portability problem with GCC 2.7.2.1 reported by Thomas M.Ott. 2005-09-27 Paul Eggert * modules/regex (Depends-on): Add strcase. * modules/gethostname (Licence): Change from GPL to LGPL, since gethostname.c is a trivial implementation of a standard library function. * modules/poll (License): Change from GPL to LGPL, since it's derived from LGPL code. 2005-09-27 Jim Meyering * lib/getcwd.c: Change #ifdefHAVE_CONFIG_H to #ifdef HAVE_CONFIG_H. * lib/intprops.h (signed_type_or_expr__): Define. (INT_STRLEN_BOUND) [__GNUC__]: Use a slightly tighter bound for unsigned types. 2005-09-26 Paul Eggert * lib/verify.h (verify_expr): Remove, replacing with: (verify_true): New macro that returns true instead of void. (verify_type__): Remove. (verify): Use verify_true rather than verify_type__. 2005-09-26 Bruno Haible * modules/mbchar (Include): Mention that HAVE_WCHAR_H && HAVE_WCTYPE_H is necessary. (lib_SOURCES): Remove mbchar.c. * modules/mbfile (Include): Mention that HAVE_MBRTOWC is necessary. (Files): Add m4/mbrtowc.m4. * modules/mbiter: Likewise. * modules/mbuiter: Likewise. 2005-09-26 Bruno Haible * m4/mbchar.m4 (gl_MBCHAR): Check for wchar.h and wctype.h. Don't compile mbchar.c if they are not both present. * m4/mbfile.m4 (gl_MBFILE): Require gl_FUNC_MBRTOWC. * m4/mbiter.m4 (gl_MBITER): Likewise. * m4/strstr.m4 (gl_PREREQ_STRSTR): Use AC_REQUIRE. * m4/strcasestr.m4 (gl_PREREQ_STRCASESTR): Likewise. * m4/strcase.m4 (gl_PREREQ_STRCASECMP): Likewise. 2005-09-25 Jim Meyering * modules/inet_ntop (Depends-on): Add socklen, since inet_ntop.c also uses socklen_t. 2005-09-24 Paul Eggert * lib/utimens.c (ENOSYS): Define if not already defined. (futimens): Support having a null PATH if the file descriptor is nonnegative. * lib/regex_internal.h (__GNUC_PREREQ, always_inline, inline, pure): Remove. (__attribute): Define to empty unless GCC 3.1 or later. This works around a core dump on OpenBSD 3.4, which has GCC 2.95.3, which dumps core when given __attribute__(()). It also simplifies other tests, since we really don't want to bother with worrying about which ancient version of GCC supported what. Original problem reported by Yoann Vandoorselaere, with part of the fix suggested by Derek Price. 2005-09-24 Jim Meyering * lib/verify.h (verify_type__): Use `unsigned int' as the bitfield type so we can once again use a positive bitfield width of 1 -- now we don't have to explain why we were using a bitfield width of 2. 2005-09-23 Paul Eggert * m4/regex.m4 (gl_REGEX): If replacing, define regcomp to rpl_regcomp, and similarly for the other external symbols. Problem reported by James Gallager. * m4/fnmatch.m4 (_AC_FUNC_FNMATCH_IF): Catch Sun Studio 10u1 on Linux bug reported by Jim Meyering. * m4/utimens.m4 (gl_UTIMENS): Check for futimesat. * m4/getaddrinfo.m4 (gl_PREREQ_GETADDRINFO): Undo previous change; not needed, since socklen is a prerequisite module. 2005-09-23 Paul Eggert * lib/getaddrinfo.c [HAVE_NETINET_IN_H]: Include . Problem reported by Eric Blake. (getaddrinfo): Initialize se so that it's not garbage. Redo internal storage allocation so that it doesn't make unportable assumptions about alignment. Fix a memory leak. * lib/utimens.c (futimens): Use futimesat if available. Prefer it to futimes since it doesn't have the futimes bug. * lib/verify.h (GL_CONCAT0, GL_CONCAT): Remove. (verify): Don't use the __LINE__ trick, as it doesn't work in general. Instead, declare a function that returns a pointer to an array, and use verify_type__ to declare the size of the array. Problem and germ of a solution reported by Bruno Haible. (verify_type__): Use 2, not 1, for bitfield size, to avoid a warning with Irix 6.5 cc. Problem reported by Bruno Haible. 2005-09-23 Jim Meyering Sync from coreutils. Correct build failure (socklen_t not defined) on at least mips-sgi-irix6.5 and alphaev67-dec-osf5.1. * m4/getaddrinfo.m4 (gl_PREREQ_GETADDRINFO): Require gl_SOCKLEN_T. 2005-09-23 Jim Meyering * modules/getaddrinfo (Depends-on): Add socklen. 2005-09-23 Bruno Haible * tests/test-verify.c: New file. 2005-09-22 Paul Eggert Sync from coreutils. * modules/argmatch (Depends-on): Add verify. * modules/getloadavg (Depends-on): Depend on fcntl-safer, not unistd-safer. * modules/save-cwd (Depends-on): Likewise. * modules/openat (Files): Add lib/openat-die.c. (Depends-on): Remove error, exitfail. Add dirname. * modules/verify: New file. * MODULES.html.sh (Diagnostics ): New section, with "verify" module. 2005-09-22 Paul Eggert Sync from coreutils. * m4/backupfile.m4, calloc.m4, chown.m4, cloexec.m4, dup2.m4: * m4/fileblocks.m4, free.m4, ftruncate.m4, getcwd.m4, getpagesize.m4: * m4/getugroups.m4, group-member.m4, idcache.m4, link-follow.m4: * m4/mkstemp.m4, mktime.m4, mountlist.m4, nanosleep.m4, pathmax.m4: * m4/physmem.m4, posixver.m4, putenv.m4, safe-read.m4, same.m4: * m4/save-cwd.m4, stdio-safer.m4, unistd-safer.m4, unlinkdir.m4: * m4/userspec.m4, xgetcwd.m4, xreadlink.m4: Don't bother checking for string.h, stdlib.h, unistd.h. * m4/fts.m4 (gl_FUNC_FTS_CORE): Don't require AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK; that's now the lstat module's job. * m4/jm-macros.m4 (gl_MACROS): Likewise. * m4/prereq.m4 (gl_PREREQ): Add gl_FUNC_LSTAT. * m4/getdate.m4 (gl_C_COMPOUND_LITERALS): New macro. (gl_GETDATE): Use it. * m4/mkdir-p.m4 (gl_MKDIR_PARENTS): Don't bother checking for unistd.h. 2005-09-22 Paul Eggert Sync from coreutils. * lib/.cppi-disable: Add regcomp.c, regex_internal.c, regex_internal.h, stat-time.h. * lib/argmatch.h: Include verify.h (ARGMATCH_VERIFY): Use verify rather than rolling our own. (ARGMATCH_ASSERT): Remove; unused. * lib/canonicalize.c: Assume STDC_HEADERS. * lib/exclude.c: Include "strcase.h". * lib/regex_internal.h [!defined _LIBC]: Likewise. * lib/getusershell.c: Include stdio--.h rather than stdio.h and stdio-safer.h. (getusershell): Call fopen, not fopen_safer. * lib/save-cwd.c: Include fcntl--.h rather than fcntl.h. Do not include unistd-safer.h. (save_cwd): Don't call fd_safer; no longer needed now that we include fcntl--.h. * lib/getdate.y (relative_time): New type. (RELATIVE_TIME_0): New constant. (parser_control): Use relative_time instead of doing it ourselves. (%union): Add new relative_time rel member. (tYEAR_UNIT, tMONTH_UNIT, tHOUR_UNIT, tMINUTE_UNIT, tSEC_UNIT): Now typeless. (relunit, relunit_snumber): Now of type rel. (zone, rel, relunit, get_date): Adjust to above changes. * lib/getloadavg.c: Include fcntl--.h rather than fcntl.h. Do not include unistd-safer.h. (getloadavg): Don't call fd_safer; no longer needed now that we include fcntl--.h. * lib/mkdir-p.c (ENOSYS): Define to EEXIST if not defined. (make_dir_parents): Treat ENOSYS like EEXIST. Improve quality of diagnostics on restore_cwd failure. * lib/mkdir-p.h (make_dir): Remove. All uses replaced by mkdir. (make_dir_parents): Last arg is now int * (for errno), not bool *. * lib/mkdir-p.c (make_dir, make_dir_parents): Likewise. Rewrite "mkdir -p" algorithm to avoid the need for "stat" each time through the loop. Do not diagnose restore_cwd failure; that is the caller's job (and perhaps the caller does not care). * lib/mkdir-p.c (CLEANUP_CWD, CLEANUP): Remove. (make_dir_parents): Revamp to avoid need for CLEANUP_CWD, CLEANUP. If the file already exists but is not a directory, don't bother to try to make its parents. Close potential file descriptor leak if we can't chdir("/") (!). Don't always return true if chdir($PWD) fails; return true only if the requested action was done successfully (except for the chdir($PWD)). Don't log final directory unless we actually made it. Refactor to avoid duplicate code to fix up permissions. Don't attempt to fix up parent permissions if chdir($PWD) fails. * lib/strftime.c (my_strftime): Rewrite the previous change slightly, to make it a bit faster and (I hope) clearer. * lib/strftime.c (my_strftime): Add support for %:z, %::z, %:::z. Fix bug in formats like %2N. * lib/verify.h: New file. 2005-09-22 Paul Eggert Sync from coreutils. * m4/getaddrinfo.m4 (gl_PREREQ_GETADDRINFO): Check for netinet/in.h. 2005-09-22 Jim Meyering Sync from coreutils. * m4/lstat.m4 (gl_FUNC_LSTAT): Use AC_LIBSOURCES to require lstat.c and lstat.h. Remove obsolete comment. * m4/xreadlink.m4: Use AC_LIBSOURCES and AC_LIBOBJ. * m4/xstrtod.m4: Likewise. * m4/openat.m4 (gl_FUNC_OPENAT): Add openat-die.c. 2005-09-22 Jim Meyering Sync from coreutils. * lib/backupfile.c: Use ARGMATCH_VERIFY, just in case. * lib/posixtm.c (posixtime) [lint]: Initialize *all* of tm0, not just the .tm_year member, since otherwise gcc-4.0 would now warn about tm_zone, tm_gmtoff, tm_isdst, tm_yday, tm_wday. * lib/quotearg.c (quotearg_n_options): Change code to be suboptimal, in order to avoid an unsuppressible warning from gcc on 64-bit systems. * lib/getdate.y (get_date): Undo part of the 2005-04-04 change, so that the command "date -d'2005-03-27 +1 day'" succeeds once again, even when run in a time zone for which daylight savings time is in effect for the starting date. * lib/mkdir-p.c (make_dir_parents): Don't let a failed chdir($PWD) stop us from restricting permissions of just-created absolute-named directories. * lib/mkdir-p.c (CLEANUP_CWD): Return *true*, not false when failing to restore initial working directory. * lib/mkdir-p.c (make_dir_parents): New parameter: different_working_dir, to tell caller if/when we change the working directory and are unable to return to the initial one. * lib/mkdir-p.h (make_dir_parents): Update prototype. * lib/mkdir-p.c (CLEANUP_CWD): Change one more `return 1' to `return false'. This fixes a bug introduced on 2004-07-30. * lib/openat.c (fdopendir): Be sure to close the supplied file descriptor before returning. This makes our replacement implementation a little closer to Solaris's, where fdopendir ties the file descriptor to the returned DIR* pointer. * lib/openat.c (unlinkat): New function. * lib/openat.h (unlinkat): Add prototype. * lib/openat-die.c (openat_save_fail): Rename from openat_save_die. (openat_restore_fail): Rename from openat_restore_die. * lib/openat.c, openat.h: Reflect s/_die/_fail/ renaming. Provide an alternative to exiting immediately upon save_cwd or restore_cwd failure. Now, an application can arrange e.g., to perform a longjump in that case. * lib/openat.c: Include dirname.h. Use IS_ABSOLUTE_FILE_NAME rather than testing for leading slash. (rpl_openat, fdopendir, fstatat): Call openat_save_die and openat_restore_die rather than calling error directly. Don't include "error.h" or "exitfail.h"; they're no longer needed. * lib/openat-die.c (openat_save_die, openat_restore_die): New file. * lib/openat.h (openat_save_die, openat_restore_die): Declare and define. * lib/strftime.c [FPRINTFTIME] (fprintftime): Provide a new interface: size_t fprintftime (FILE *fp, char const *fmt, struct tm const *tm, int utc, int nanoseconds); Background: date should not have to allocate a megabyte of virtual memory to handle a format argument like +%1048575T. When implemented with strftime, it must allocate such a buffer, use strftime to fill it in, print it, then free it. With fprintftime, it simply prints everything and exits. With no need for memory allocation, that's one fewer way to fail. * lib/strftime.c (my_strftime): Parse the colons of %:::z *after* the optional field width, not before, so we accept %9:z, not %:9z.

Port bitset code to hosts with unusual word sizes. * lib/regcomp.c (build_equiv_class, build_charclass, build_range_exp): (build_collating_symbol): Prefer bitset to re_bitset_ptr_t in prototypes, when the actual argument is a bitset. This is merely a style issue, but it makes it clearer that an entire array is expected. (re_compile_fastmap_iter, init_dfa, init_word_char, optimize_subexps): * lib/regcomp.c (lower_subexp, parse_bracket_exp, built_charclass_op): Port to the case where bitset_word is not the same as unsigned int. * lib/regex_internal.h (bitset_set, bitset_clear, bitset_contain): (bitset_not, bitset_merge, bitset_set_all, bitset_mask): Likewise. * lib/regexec.c (check_dst_limits_calc_pos_1, check_subexp_matching_top): (build_trtable, group_nodes_into_DFAstates): Likewise. * lib/regcomp.c (re_compile_fastmap_iter, utf8_sb_map, optimize_utf8): Don't assume that SBC_MAX is a multiple of BITSET_WORD_BITS. * lib/regex_internal.h (bitset_set_all, bitset_not): Likewise. * lib/regexec.c (group_nodes_into_DFAstates): Likewise. * lib/regcomp.c (utf8_sb_map): Don't assume UINT_MAX == 0xffffffff. * lib/regcomp.c (optimize_subexps, lower_subexp): Work even if bitset_word has holes in its bitwise representation. * lib/regex_internal.h (BITSET_WORD_BITS): Likewise. * lib/regexec.c (check_dst_limits_calc_pos_1, check_subexp_matching_top): Likewise. * lib/regex_internal.c (re_string_reconstruct): Don't assume UCHAR_MAX == 255. * lib/regex_internal.h (bitset_set_all): Likewise. * lib/regex_internal.h (BITSET_WORD_BITS): Renamed from UINT_BITS. All uses changed. (BITSET_WORDS): Renamed from BITSET_UINTS. All uses changed. (bitset_word): New type, replacing 'unsigned int' for bitset uses. All uses changed. (BITSET_WORD_MAX): New macro. (bitset_set, bitset_clear, bitset_contain, bitset_empty): (bitset_set_all, bitset_copy): Now inline functions, not macros. (bitset_empty, bitset_copy): Prefer sizeof (bitset) to multiplying it out ourselves. (bitset_not_merge): Remove; unused. (bitset_contain): Return bool, not unsigned int with one bit on. All callers changed. * lib/regexec.c (build_trtable): Don't assume bitset has no stricter alignment than re_node_set; do this by defining a new internal type struct dests_alloc and using it to allocate memory. 2005-09-05 Bruno Haible * gnulib-tool (func_import): Fix comparison in handling of symbolic links. 2005-09-04 Martin Lambers (tiny change) * modules/size_max (Makefile.am): Add size_max.h 2005-09-04 Derek Price * gnulib-tool (func_import): Fix reversed $symbolic logic. 2005-09-03 Simon Josefsson * gnulib-tool: Fix typo. 2005-09-03 Simon Josefsson * config/srclist.txt: Add glibc bug 1293. 2005-09-03 Derek Price * m4/getlogin_r (gl_GETLOGIN_R): Fix cut & paste error.

These patches are conservative, in the sense that when I couldn't determine whether an overflow was possible, I inserted a run-time check. * lib/regex_internal.h (re_xmalloc, re_xrealloc, re_x2realloc): New macros. (SIZE_MAX) [!defined SIZE_MAX]: New macro.

This patch fixes this when the regex code is used in gnulib (i.e., outside glibc). This patch should not affect the use of the regex code inside glibc. No doubt this problem also needs to be handled for glibc as well, but the result will be an incompatible change to the glibc ABI, and the old ABI will have to be supported too. That can be the subject for another patch. * lib/regex.h (_REGEX_LARGE_OFFSETS): New feature-test macro, governing whether the rest of this patch is active. By default, the macro is disabled and the patch has no effect. (regoff_t) [defined _REGEX_LARGE_OFFSETS]: Define to off_t, not int. (__re_idx_t, __re_size_t, __re_long_size_t): New types.

This avoids overflow problems when regoff_t is the same width as size_t. All callers changed. (re_search_2_stub): Check for overflow when adding the sizes of the two strings. (re_search_stub): Check for overflow when adding START to RANGE; if it occurs, substitute the extreme value. 2005-08-31 Paul Eggert * config/srclist.txt: Add glibc bugs 1273, 1278-1282, 1284. 2005-08-31 Jim Meyering * lib/regcomp.c (search_duplicated_node): Make first pointer arg a pointer-to-const. * lib/regex_internal.c (create_ci_newstate, create_cd_newstate): (register_state): Likewise. * lib/regexec.c (search_cur_bkref_entry, check_dst_limits): (check_dst_limits_calc_pos_1, check_dst_limits_calc_pos): (group_nodes_into_DFAstates): Likewise. 2005-08-31 Jim Meyering * check-module: Add a FIXME comment. 2005-08-31 Eric Blake * modules/unistd-safer (Files): Add unistd--.h. * modules/stdio-safer (Files): Add stdio--.h. 2005-08-31 Derek Price * lib/getdelim.c (getdelim): Return EOF on EOF.

(The code never needed it.) * lib/regcomp.c, regex_internal.c, regex_internal.h, regexec.c: All uses of recently-renamed identifiers changed to use the new, POSIX-compliant names. The code will build and run just fine without these changes, but it's better to eat our own dog food and use the standard-conforming names. * lib/regex.h: Fix a multitude of POSIX name space violations. These changes have an effect only for programs that define _POSIX_C_SOURCE, _POSIX_SOURCE, or _XOPEN_SOURCE; they do not change anything for programs compiled in the normal way. Also, there is no effect on the ABI. (_REGEX_SOURCE): New macro. Do not include if _XOPEN_SOURCE and VMS are both defined and _GNU_SOURCE is not; this fixes a name space violation. Rename the following macros to obey POSIX requirements. The old names are still visible as macros if _REGEX_SOURCE is defined.

(REG_CONTEXT_INVALID_DUP): renamed from RE_CONTEXT_INVALID_DUP. (REG_NO_SUB): renamed from RE_NO_SUB. (REG_SYNTAX_EMACS): renamed from RE_SYNTAX_EMACS. (REG_SYNTAX_AWK): renamed from RE_SYNTAX_AWK.

(REG_SYNTAX_POSIX_MINIMAL_BASIC): renamed from RE_SYNTAX_POSIX_MINIMAL_BASIC. (REG_SYNTAX_POSIX_EXTENDED): renamed from RE_SYNTAX_POSIX_EXTENDED. (REG_SYNTAX_POSIX_MINIMAL_EXTENDED): renamed from RE_SYNTAX_POSIX_MINIMAL_EXTENDED. (REG_DUP_MAX): renamed from RE_DUP_MAX. No need to undef it. (REG_UNALLOCATED): Renamed from REGS_UNALLOCATED. (REG_REALLOCATE): Renamed from REGS_REALLOCATE. (REG_FIXED): Renamed from REGS_FIXED. (REG_NREGS): Renamed from RE_NREGS. (REG_ICASE, REG_NEWLINE, REG_NOSUB): Do not depend on the values of other REG_* macros, since POSIX says the user is allowed to #undef these macros selectively. (reg_errcode_t): Update comment stating what other tables need to be consistent. Rename the following enum values to obey POSIX requirements. The old names are still visible as macros. (_REG_ENOSYS): Renamed from REG_ENOSYS. Define even if _XOPEN_SOURCE is not defined, since GNU is supposed to be a superset of POSIX as much as possible, and since we want reg_errcode_t to be a signed type for implementation consistency. (_REG_NOERROR): Renamed from REG_NOERROR. (_REG_NOMATCH): Renamed from REG_NOMATCH. (_REG_BADPAT): Renamed from REG_BADPAT. (_REG_ECOLLATE): Renamed from REG_ECOLLATE.

(_REG_BADRPT): Renamed from REG_BADRPT. (_REG_EEND): Renamed from REG_EEND. (_REG_ESIZE): Renamed from REG_ESIZE. (_REG_ERPAREN): Renamed from REG_ERPAREN. (REG_ENOSYS, REG_NOERROR, REG_NOMATCH, REG_BADPAT, REG_ECOLLATE): (REG_ECTYPE, REG_EESCAPE, REG_ESUBREG, REG_EBRACK, REG_EPAREN): (REG_EBRACE, REG_BADBR, REG_ERANGE, REG_ESPACE, REG_BADRPT, REG_EEND): (REG_ESIZE, REG_ERPAREN): Now macros, not enum constants. (_REG_RE_NAME, _REG_RM_NAME): New macros. (REG_TRANSLATE_TYPE): Renamed from RE_TRANSLATE_TYPE. All uses changed. But support the old name if the new one is not defined and if _REGEX_SOURCE. Change the following member names in struct re_pattern_buffer. The old names are still supported if !_REGEX_SOURCE. The new names are always supported, regardless of _REGEX_SOURCE.

(re_set_syntax, re_compile_pattern, re_compile_fastmap): (re_search, re_search_2, re_match, re_match_2, re_set_registers): Prepend __ to parameter names. Undo yesterday's changes. 2005-08-24 Paul Eggert * config/srclist.txt: Remove glibc bug 1233 and add 1236, which supersedes it. Add glibc bugs 1237, 1238, 1240.

All contents moved to gl_REGEX. (gl_REGEX): Don't bother checking whether lib/regex.c exists; assume that it does. 2005-08-23 Paul Eggert * lib/regex.h (REG_NOSYS) [!defined _XOPEN_SOURCE && 200112L <= _POSIX_C_SOURCE]: Define, since POSIX requires it as of 2001.

This causes a warning with GCC 4.0.0, and anyway in the typical case it's not worth the extra 100 bytes or so of code. (ranged_convert, __mktime_internal): When calling a function via a pointer P, use P () rather than (*P) (), as we now assume C89 or better. 2005-06-22 Paul Eggert * lib/readutmp.c (desirable_utmp_entry): Fix bug where "who -b" and "who -r" failed to give output. Problem reported by Tim Waugh. * lib/xmalloc.c (HAVE_GNU_CALLOC): New constant. (xcalloc): Use it to avoid needless tests.

Don't check for fcntl.h, stddef.h, stdlib.h, string.h, unistd.h, since we include them unconditionally. Don't require AM_STDBOOL_H, since stdbool is a prerequisite. Don't require AC_C_CONST, AC_TYPE_SIZE_T or check for ptrdiff_t since we assume C89 or better. Don't require AC_FUNC_CLOSEDIR_VOID, AC_FUNC_LSTAT, or AC_FUNC_STAT, as we don't use their results. Don't check for fchdir, memmove, memset, strrchr, as we use them unconditionally. * m4/gettimeofday.m4 (AC_FUNC_GETTIMEOFDAY_CLOBBER): Don't define GETTIMEOFDAY_CLOBBERS_LOCALTIME_BUFFER, since nobody uses it. 2005-05-18 Paul Eggert * lib/canonicalize.c: Include canonicalize.h first, to test interface. Include unconditionally, since we assume C89 now. All uses of PTR_INT_TYPE replaced by ptrdiff_t. * lib/fts.c: Include fts_.h first, to check interface. Do not include intprops.h; no longer needed. Include cycle-check.h and hash.h, since fts_.h no longer does. Remove unnecessary casts of closedir to void. (fts_build): Use a simpler method (not involving TYPE_SIGNED) to decide whether to decrement nlinks. * lib/fts_.h: Do not include hash.h or cycle-check.h; no longer needed. (FTS): Use struct hash_table * instead of Hash_table, so that we no longer need to include hash.h here. 2005-05-18 Jim Meyering * modules/dirfd (License): Change to LGPL. Most of the code is already in the public domain. 2005-05-18 Jim Meyering * m4/fts.m4 (AC_LIBSOURCES): Add intprops.h to the list.

date syntax): Don't say that date date --iso-8601=ns generates acceptable dates; it doesn't yet. Problem reported by Nic Ferrier. 2005-05-10 Yoann Vandoorselaere * lib/getaddrinfo.c: Don't fail when SOCK_STREAM or SOCK_DGRAM are specified in ai_socktype. Fix invalid ai_protocol check. ai_protocol is usually set to 0 or depending on ai_family/ai_socktype to IPPROTO_TCP / IPPROTO_UDP. Checking for SOCK_STREAM / SOCK_DGRAM in ai_protocol was invalid. Set ai_socktype / ai_protocol in the returned addrinfo structure. 2005-05-10 Simon Josefsson * m4/getaddrinfo.m4: Look in libnsl/libsocket for getaddrinfo, from Yoann Vandoorselaere . 2005-05-10 Karl Berry * doc/fdl.texi, gpl.texi, lgpl.texi, COPYING: update FSF address (from http://www.gnu.org/licenses). * doc/COPYING.LIB: also rename to COPYING.LESSER. * doc/COPYING.DOC: remove; per rms, only needed in doc files, so fdl.texi suffices. 2005-05-10 Karl Berry * config/srclist.txt (COPYING.LESSER): rename from COPYING.LIB. (COPYING.DOC): remove. * config/srclist-update: new FSF address. 2005-05-10 Derek Price * m4/getopt.m4 (gl_GETOPT): Check for Solaris 10 bug, not decl, when possible. 2005-05-09 Yoann Vandoorselaere Bruno Haible * modules/inet_ntop: New file. * MODULES.html.sh (Support for systems lacking POSIX:2001): Add inet_ntop. 2005-05-09 Yoann Vandoorselaere Bruno Haible * m4/inet_ntop.m4: New file. 2005-05-09 Yoann Vandoorselaere Bruno Haible * lib/inet_ntop.h: New file. * lib/inet_ntop.c: New file, from glibc with modifications. 2005-05-09 Paul Eggert * modules/time_r (License): Change to LGPL. * modules/extensions (License): Change to LGPL. Actually, the license is more permissive than that, but currently gnulib-tool doesn't know how to handle more-permissive licenses. * modules/stat-macros (Depends-on): Don't depend on stat-macros (!).

Among other things, add bulletproofing for cases where stdin, stdout, or stderr are closed. * lib/fd-safer.c: New file. * lib/fcntl-safer.h, open-safer.c: Remove. * lib/chdir-long.c: Fix comment "fetish" -> "coreutils". * lib/dup-safer.c: Include unistd-safer.h first. Don't include errno.h. (dup_safer) [!defined F_DUPFD]: Let fd_safer do the real work. * lib/file-type.h: Don't assume invoker included sys/stat.h first. * lib/file-type.c: Rely on file-type.h change. * lib/getloadavg.c: Include unistd-safer.h.

(getusershell): Use safer fopen. * lib/long-options.c (long_options): Use NULL rather than 0. * lib/modechange.h (mode_free): Remove; all callers changed to invoke 'free'. * lib/modechange.c: Likewise. xstrtol.h, stdbool.h, stddef.h: Don't include; no longer needed. (MODE_DONE): New constant. (struct mode_change): Remove 'next' member. (make_node_op_equals): New function; like the old one of the same name, except it allocates an array. (mode_compile, mode_create_from_ref): Use it. (mode_compile): Allocate result as an array, not a linked list. Parse octal string ourself, so that we catch mistakes like "+0". (mode_adjust): Arg is an array, not a linked list. * lib/modechange.c: Include stat-macros.h, xalloc.h. (S_ISDIR, S_ISUID, S_ISGID, S_ISVTX, S_IRUSR, S_IWUSR, S_IXUSR): (S_IRGRP, S_IWGRP, S_IXGRP, S_IROTH, S_IWOTH, S_IXOTH, S_IRXWU): (S_IRWXG, S_IRWXO, CHMOD_MODE_BITS): Remove.

(mode_compile): Remove MASKED_OPS arg, since it encouraged apps to have incorrect behavior. Use simpler algorithm for head and tail. Don't futz with umask; that's now the job of mode_adjust. Detect more invalid usages rather than having somewhat-random behavior. Don't insert an "a=" action, as that leads to incorrect behavior. (mode_compile, mode_create_from_ref): Return NULL on error instead of an enum, since now there's only one way to have an error. All callers changed. (mode_adjust): Accept new arg UMASK_VALUE, and interpret it at the correct time. Simplify calculation of "+u" and its ilk. Don't mishandle "+X". (mode_free): Remove "register" and localize decls. * lib/modechange.h (MODE_X_IF_ANY_X, MODE_COPY_EXISTING): (struct mode_change): Move to modechange.c; callers don't need to see this stuff.

(mode_change, mode_adjust): Reflect the new signatures noted above. * lib/nanosleep.c (rpl_nanosleep): Include "timespec.h" before macros that might redefine system include files. (siginterrupt) [!HAVE_SIGINTERRUPT]: New macro. (my_usleep): Use NULL rather than (void *) 0. (rpl_nanosleep) [!defined SA_NOCLDSTOP]: Use siginterrupt to specify that system calls should be interrupted. (rpl_nanosleep): Move initialization of suspended closer to call of my_usleep. * lib/readutmp.h (read_utmp): New arg OPTIONS. All uses changed. * lib/readutmp.c: Likewise. Include signal.h, stdbool.h. (desirable_utmp_entry): New function. (read_utmp) [defined UTMP_NAME_FUNCTION]: Redo memory allocation using x2nrealloc, to simplify logic.

(gl_PREREQ_CHOWN): Remove. * m4/lstat.m4 (gl_FUNC_LSTAT): Require AC_FUNC_LSTAT instead of calling it. Don't require AC_HEADER_STAT. (gl_PREREQ_LSTAT): Remove. * m4/mkstemp.m4 (gl_PREREQ_TEMPNAME): Check stdint.h only once. Don't require AC_HEADER_STAT. * m4/rmdir.m4 (gl_FUNC_RMDIR): Don't require AC_HEADER_STAT. (gl_PREREQ_RMDIR): Remove. * m4/canonicalize.m4 (AC_FUNC_CANONICALIZE_FILE_NAME): Don't mention stat-macros.h or AC_HEADER_STAT, since we'll make the stat-macros module a prerequisite. * m4/file-type.m4 (gl_FILE_TYPE): Likewise. * m4/filemode.m4 (gl_FILEMODE): Likewise. * m4/makepath.m4 (gl_MAKEPATH): Likewise. * m4/modechange.m4 (gl_MODECHANGE): Likewise. * m4/clock_time.m4 (gl_CLOCK_TIME): Use gl_ rather than fetish_ for variable names. * m4/rmdir-errno.m4 (gl_FUNC_RMDIR_NOTEMPTY): Renamed from fetish_FUNC_RMDIR_NOTEMPTY. All uses changed. Use gl_ for variable prefixes. * m4/fcntl-safer.m4: Remove. * m4/stdio-safer.m4 (gl_STDIO_SAFER): Use AC_LIBSOURCES and AC_LIBOBJ. * m4/unistd-safer.m4 (gl_UNISTD_SAFER): Likewise.

Add --aux-dir, specifying directory relative --dir where auxiliary build tools are placed. 2005-04-14 Bruno Haible * modules/allocsa (License): Change to LGPL. Requested by Yoann Vandoorselaere . 2005-04-13 Paul Eggert * lib/getdate.y (zone): Allow relunit_snumber after tZONE, so that "UTC +1 second" continues to work. Problem reported by Dmitry V. Levin.

Problem reported by Ian Abbott. 2005-04-12 Jim Meyering * lib/human.c (humblock): Set *options even when returning due to xstrtoumax conversion failure. Thanks to a used-uninitialized warning from gcc-4. 2005-04-09 Jim Meyering * lib/posixtm.c (posixtime) [lint]: Avoid spurious warning from gcc-4's -Wuninitialized: initialize tm0.tm_year. 2005-04-04 Paul Eggert * lib/getdate.y (parser_control): rels_seen is now a boolean, not a count, since there's no maximum. All uses changed. Add member dsts_seen. (local_zone): Accumulate dsts_seen rather than relying on tm_isdst not being INT_MAX. (get_date): Initialize dsts_seen, and check that it doesn't go over 1. Use pc_rels_seen to decide whether a date is absolute. * lib/getdate.y (number): Don't overwrite year.

(path_concat): Remove assertion that would have triggered for ABASE starting with more than one slash. Reported by Andreas Schwab. * lib/path-concat.c (path_concat): Set *BASE_IN_RESULT properly when ABASE is an absolute file name. Correct the description of this function. Include . Add an assertion and a test driver. This fixes a bug introduced on 2004-07-02. Andreas Schwab reported the resulting failure of cp --parents: http://lists.gnu.org/r/bug-coreutils/2005-01/msg00130.html 2005-03-21 Jim Meyering * m4/chdir-long.m4 (gl_PREREQ_CHDIR_LONG): Invoke gl_FUNC_MEMRCHR. * m4/memrchr.m4 (gl_FUNC_MEMRCHR): Check for memrchr decl. 2005-03-21 Jim Meyering and Paul Eggert * m4/acl.m4, m4/backupfile.m4, m4/c-strtod.m4, m4/canon-host.m4, m4/canonicalize.m4, m4/cloexec.m4, m4/closeout.m4, m4/dirfd.m4, m4/dirname.m4, m4/exclude.m4, m4/exitfail.m4, m4/file-type.m4, m4/filemode.m4, m4/fpending.m4, m4/fsusage.m4, m4/getcwd.m4, m4/getdate.m4, m4/getline.m4, m4/getpagesize.m4, m4/getpass.m4, m4/getugroups.m4, m4/group-member.m4, m4/hard-locale.m4, m4/hash.m4, m4/human.m4, m4/idcache.m4, m4/inttostr.m4, m4/long-options.m4, m4/makepath.m4, m4/md5.m4, m4/memcasecmp.m4, m4/memcoll.m4, m4/modechange.m4, m4/mountlist.m4, m4/nanosleep.m4, m4/path-concat.m4, m4/pathmax.m4, m4/physmem.m4, m4/posixtm.m4, m4/posixver.m4, m4/quote.m4, m4/quotearg.m4, m4/readtokens.m4, m4/readutmp.m4, m4/safe-read.m4, m4/safe-write.m4, m4/same.m4, m4/savedir.m4, m4/settime.m4, m4/sha1.m4, m4/sig2str.m4, m4/strdup.m4, m4/strftime.m4, m4/strndup.m4, m4/strverscmp.m4, m4/timespec.m4, m4/unlocked-io.m4, m4/userspec.m4, m4/utimecmp.m4, m4/utimens.m4, m4/xalloc.m4, m4/xnanosleep.m4, m4/xstrtol.m4, m4/yesno.m4: Use AC_LIBSOURCES and AC_LIBOBJ to indicate source and object files for these modules. 2005-03-18 Paul Eggert * lib/strftime.c (my_strftime): If the underlying strftime returns 0 (which shouldn't happen), generate nothing instead of returning 0 immediately, so that nstrftime (NULL, ...) doesn't return 0. 2005-03-16 Bruno Haible * modules/stdint (Makefile.am): Use HAVE_LONG_LONG_64BIT instead of HAVE_LONGLONG_64BIT. 2005-03-16 Bruno Haible * m4/stdint.m4 (gl_STDINT_H): Define HAVE_LONG_LONG_64BIT instead of HAVE_LONGLONG_64BIT. 2005-03-16 Bruno Haible * lib/stdint_.h: Use HAVE_LONG_LONG_64BIT instead of HAVE_LONGLONG_64BIT. 2005-03-15 Paul Eggert * lib/strftime.c (my_strftime): Prepend space to format so that we can reliably distinguish strftime failure from empty output on POSIX hosts. 2005-03-15 Paul Eggert * lib/iconvme.c (SIZE_MAX): New macro, if not already defined. (iconv_string): Don't guess a size-zero buffer, as that might cause buffer overrun. Instead, avoid multiplying by MB_LEN_MAX if the result would be 'too large', where 'too large' is (heuristically) the square root of SIZE_MAX, divided by MB_LEN_MAX to allay overflow concerns. This will prevent some unwanted malloc failures when the inputs are very large. 2005-03-15 Karl Berry * config/srclist.txt (config.rpath): from gettext. * config/config.rpath: update. 2005-03-15 Bruno Haible * lib/regex.c (byte_re_match_2_internal): Rename local variable 'not' to 'negate'. * lib/regex.c (byte_re_match_2_internal): Reduce scope of same_str_p variable. * lib/regex.c (EXTEND_BUFFER, regcomp): Cast the realloc/malloc results. 2005-03-14 Simon Josefsson * lib/timegm.h: Use proper prototype CPP guards, reported by Dave Love . 2005-03-14 Paul Eggert * lib/mktime.c (TYPE_TWOS_COMPLEMENT, TYPE_ONES_COMPLEMENT, TYPE_SIGNED_MAGNITUDE, TYPE_MINIMUM, TYPE_MAXIMUM): Sync from intprops.h. * lib/strtol.c: Likewise. 2005-03-14 Jim Meyering * lib/strftime.c (my_strftime) [HAVE_STRFTIME && ! (_NL_CURRENT && HAVE_STRUCT_ERA_ENTRY)]: Initialize the first byte of ubuf[] to be nonzero so that we (and caller) can detect the difference between a valid zero-length expansion and an error return, even when the underlying strftime fails before writing anything into that location. 2005-03-14 Bruno Haible * m4/lib-link.m4, gettext.m4, nls.m4, po.m4: Update from GNU gettext 0.14.3. 2005-03-10 Jim Meyering * m4/save-cwd.m4 (gl_SAVE_CWD): Check for fchdir. 2005-03-10 Jim Meyering * lib/save-cwd.c [!HAVE_FCHDIR]: Define open, fchdir, and chdir_long so that this module works on systems without fchdir. 2005-03-09 Paul Eggert Factor int-properties macros into a single file, except for glibc-related files. * lib/intprops.h: New file. * lib/getloadavg.c: Include it instead of limits.h. (INT_STRLEN_BOUND): Remove. * lib/human.c: Include intprops.h. (group_number): Use INT_STRLEN_BOUND instead of rolling it ourself. * lib/human.h (LONGEST_HUMAN_READABLE): Use 146/485 rather than 302/1000. * lib/inttostr.h: Include intprops.h instead of limits.h.

(INT_STRLEN_BOUND): Switch to same implementation as intprops.h. * lib/strtol.c: Adjust comments to match intprops.h. * lib/userspec.c: Include intprops.h. (TYPE_SIGNED, TYPE_MINIMUM, TYPE_MAXIMUM): Remove. * lib/utimecmp.c, xnanosleep.c, xstrtol.c: Likewise. * lib/utimecmp.c (utimecmp): Use TYPE_IS_INTEGER, TYPE_TWOS_COMPLEMENT instead of rolling our own expressions. * lib/xstrtol.c: Include xstrtol.h first, to test interface. * lib/strftime.c: Include . Use bool where appropriate, instead of int. (my_strftime): Do not mishandle years close to INT_MAX, by doing the right thing even if adding 1900 would overflow. Similarly for tm_mon + 1 and tm_yday + 1. Make %Y always equivalent to %C%y, and similarly for %G and %g. (DO_NUMBER, DO_NUMBER_SPACEPAD): Set digits to d, not a conditional. (DO_SIGNED_NUMBER): New macro. (my_strftime) [HAVE_TZNAME]: Don't dump core if tp->tm_dst > 1. 2005-03-07 Bruno Haible * m4/mmap-anon.m4 (MAP_FILE, MAP_FAILED): Remove definitions. 2005-03-07 Bruno Haible * lib/pagealign_alloc.c (MAP_FILE, MAP_FAILED): Define fallbacks. 2005-03-04 Derek R.

Because of AIX, the replacement has to be done only after is included, therefore not in config.h. stpncpy.h does the replacement, and stpncpy.c uses it. 2005-03-02 Bruno Haible * lib/stpncpy.h (stpncpy): Define as a macro without arguments, so that stpncpy.c uses it. 2005-03-01 Paul Eggert Remove workaround for bug in Linux kernel 2.6.8 or thereabouts. The workaround isn't strictly needed for POSIX conformance, and it's too much of a pain to configure and maintain. We'll ask people to fix their kernels instead. * lib/xnanosleep.c: Don't include gethrxtime.h or xtime.h. (NANOSLEEP_BUG_WORKAROUND): Remove. (xnanosleep): Remove the workaround. 2005-03-01 Paul Eggert * modules/gettime (Makefile.am): Remove lib_SOURCES line. Reported by Derek Price.

All uses changed. * lib/gettime.c (gettime): Likewise. [HAVE_NANOTIME]: Prefer nanotime. Assume gettimeofday succeeds, as POSIX requires. Assime time () succeeds, since other code already does. * lib/xnanosleep.c: Include xtime.h and gethrxtime.h, not xalloc.h. (timespec_subtract): Remove. (NANOSLEEP_BUG_WORKAROUND): New constant. (xnanosleep): Use gethrxtime rather than gettime; this simplifies things considerably. Use it only on GNU/Linux hosts, since the workaround shouldn't be needed elsewhere. 2005-02-24 Bruno Haible * modules/gettext (Files): Add m4/glibc2.m4. 2005-02-24 Bruno Haible * m4/gettext.m4, intdiv0.m4, intmax.m4, inttypes-pri.m4, lcmessage.m4: * m4/lib-link.m4, lib-prefix.m4, nls.m4, po.m4, printf-posix.m4: * m4/progtest.m4: Update from GNU gettext 0.14.2. * m4/glibc2.m4: New file, from GNU gettext 0.14.2. 2005-02-24 Bruno Haible * lib/localcharset.c: Update from GNU gettext 0.14.2. * lib/config.charset: Update from GNU gettext 0.14.2. 2005-02-24 Bruno Haible * lib/gettext.h: Update from GNU gettext 0.14.2. 2005-02-23 Simon Josefsson * m4/iconvme.m4: New file. 2005-02-23 Jim Meyering * m4/extensions.m4 (gl_USE_SYSTEM_EXTENSIONS): Revert yesteday's change.

(save_cwd): Use __sgi || __sun, not sun || __sun. __sun is universal on Suns, and we also need to test for IRIX. Revamp code to use 'if' rather than '#if'. Avoid unnecessary comparison of cwd->desc to 0. * lib/utimens.c (futimens): Robustify the previous patch, by checking for known valid error numbers rather than observed invalid ones. 2005-01-18 Paul Eggert * modules/ullong_max: New file. * modules/chdir-long, modules/openat: New files. * modules/save-cwd (Depends-on): Depend on chdir-long.

Reported by Juan M. Guerrero via Stepan Kasal. * m4/(gl_FUNC_MKSTEMP): Include for the declaration of close. Remove the temporary directory right away, rather than waiting for configure's at-exit trap code to do it.

Remove now-obsolete comment about AIX. * lib/getdate.y: Include only if HAVE_ALLOCA. (YYSTACK_USE_ALLOCA): Define to 0 if !HAVE_ALLOCA. (YYMAXDEPTH): New macro. 2004-12-18 Simon Josefsson * modules/alloca: Depend on alloca-opt, instead of duplicating it. 2004-12-18 Bruno Haible * m4/fatal-signal.m4 (gl_FATAL_SIGNAL): Also test for sigaction. 2004-12-18 Bruno Haible * lib/fatal-signal.c (fatal_signals): Make non-const. (init_fatal_signals): New function. (uninstall_handlers, install_handlers): Ignore signals that were set to SIG_IGN. (at_fatal_signal): Call init_fatal_signals. (init_fatal_signal_set): Likewise. Ignore signals that were set to SIG_IGN. Reported by Paul Eggert. 2004-12-18 Bruno Haible * doc/alloca.texi: New file. * doc/alloca-opt.texi: New file. 2004-12-17 Jim Meyering * config/install-sh: Use `(exit N); exit N', not `(exit N); exit'. Otherwise, install-sh could exit with improper exit status when exiting via a trapped interrupt. Thanks to a report from Bob Proulx. 2004-12-16 Simon Josefsson * tests/test-base64.c: Add license. 2004-12-15 Stepan Kasal * gnulib-tool (func_emit_lib_Makefile_am): Shorten a long sed command. 2004-12-12 Paul Eggert * modules/getcwd (Files): Add m4/d-ino.m4. Suggested by Mark D. Baushke. 2004-12-08 Paul Eggert * lib/getdate.y (textint): New member "negative". (time_zone_hhmm): New function. Expect 14 shift-reduce conflicts, not 13. (o_colon_minutes): New rule. (time, zone): Use it to add support for +HH:MM, UTC+HH:MM. (yylex): Set the "negative" member of signed numbers. 2004-12-08 Paul Eggert * doc/getdate.texi (Time of day items, Time zone items): Describe new formats +00:00, UTC+00:00. 2004-12-07 Paul Eggert * m4/ls-mntd-fs.m4 (AC_FUNC_GETMNTENT): Fix typo in previous change: spurious "-l"s. Problem reported by Stepan Kasal. 2004-12-06 Paul Eggert * m4/ls-mntd-fs.m4 (AC_FUNC_GETMNTENT): New macro, to work around bug in Autoconf 2.59. Problem reported by Mark D. Baushke. 2004-12-04 Simon Josefsson * modules/getaddrinfo (License): Add LGPL, reported by Yoann Vandoorselaere . 2004-12-04 Paul Eggert Changes imported from coreutils. * m4/hard-locale.m4 (gl_HARD_LOCALE): Assume locale.h and setlocale exist. * m4/human.m4 (gl_HUMAN): Assume locale.h and localeconv exist. 2004-12-04 Paul Eggert Changes imported from coreutils. * lib/hard-locale.c: Assume exists. Include "strdup.h". (GLIBC_VERSION): New macro. (hard_locale): Assume setlocale exists. Rewrite to avoid #ifdef. Use strdup rather than malloc + strcpy. * lib/human.c: Assume exists. (human_readable): Assume localeconv exists. 2004-12-04 Paul Eggert * modules/hard-locale (Depends-on): Add strdup. 2004-12-01 Jakub Jelinek * lib/mktime.c (__mktime_internal): If SEC_REQUESTED != SEC, convert T2, not T. (Imported from libc.) 2004-11-30 Simon Josefsson * modules/restrict (License): Change to LGPL. 2004-11-30 Simon Josefsson * m4/restrict.m4: Add copyright and copying conditions. 2004-11-30 Simon Josefsson * m4/base64.m4: New file. 2004-11-30 Simon Josefsson * MODULES.html.sh (Extra functions based on ANSI C 89): Add base64. * tests/test-base64.c: New file. * modules/base64: New file. 2004-11-30 Paul Eggert * m4/getcwd-path-max.m4 (gl_FUNC_GETCWD_PATH_MAX): Define HAVE_PARTLY_WORKING_GETCWD if getcwd is partly working. * m4/readutmp.m4 (gl_READUTMP): Don't check for sys/param.h. 2004-11-30 Paul Eggert * lib/getcwd.c (is_ENAMETOOLONG): New macro. (__getcwd.c): Don't restore errno; glibc doesn't. [HAVE_PARTLY_WORKING_GETCWD && !defined AT_FDCWD]: Try system getcwd first, falling back to our code only if its results look suspicious. Ensure that the resulting buffer is only as large as necessary. * lib/readutmp.c: Include readutmp.h first. Include , since readutmp.h no longer does that. * lib/readutmp.h: Don't include , , ; not needed to establish interface. (errno): Remove decl. (HAVE_STRUCT_XTMP_UT_TYPE): Remove; no longer needed. (UT_TYPE_EQ, UT_TYPE_NOT_DEFINED, UT_TYPE_BOOT_TIME, UT_TYPE_USER_PROCESS, IS_USER_PROCESS): New macros. 2004-11-28 Simon Josefsson * lib/base64.h, base64.c: New file. 2004-11-27 Paul Eggert * lib/getcwd.h: New file, which I forgot to check in on 2004-11-25. 2004-11-26 Paul Eggert * modules/getcwd (Files): Add lib/getcwd.h, m4/getcwd.m4. (Depends-on): Remove pathmax, same. Add mempcpy. (configure.ac): GL_FUNC_GETCWD_PATH_MAX -> gl_FUNC_GETCWD. (Makefile.am): Append getcwd.h to lib_SOURCES. (Include): Add getcwd.h. (Maintainer): Change from Jim Meyering to "all, glibc", since getdate now uses intended-for-glibc code. * modules/xgetcwd (Files): Remove m4/getcwd.m4. (Depends-on): Depend on getcwd. Do not depend on pathmax. 2004-11-25 Paul Eggert Fix problems reported by Scott S. Tinsley for HP-UX 11.11 using HP's ANSI C compiler. * lib/fsusage.c (statvfs) [HAVE_SYS_STATVFS_H]: Remove decl. Declaring int functions causes warnings on some modern systems and shouldn't be needed to compile on ancient ones. * lib/same.c (MIN) [defined MIN]: Don't define, since it's already defined. * lib/getcwd.c: Replace by a copy of glibc/sysdeps/posix/getcwd.c, but with the following changes. (__set_errno): Parenthesize properly. Include . (MIN, MAX, MATCHING_INO): New macros. (__getcwd): Define with prototype, not K&R form. Use heuristics to allocate default buffer on stack if possible. If AT_FDCWD is defined, use openat and fstatat to avoid O(N**2) behavior, and to avoid the PATH_MAX limit when computing ../../../../... Use MATCHING_INO to compare inode number to file. Check for arithmetic overflow in size calculations. Fix bug in reallocation of dot array that caused getcwd to fail on directories nested deeper than 75. Be more careful about saving errno on error. Do not use realloc; use only free+malloc, as this is a bit more flexible and avoids a needless copy operation. Do not inspect st_dev and st_ino for symbolic links; POSIX doesn't specify the latter. Check for closedir errors. Avoid needless casts. Use "#ifdef weak_alias" around weak_alias, to be like other glibc code. The following changes to getcwd.c have effect only when used in gnulib; they have no effect inside glibc proper. (#pragma alloca) [defined _AIX && !defined __GNUC__]: Remove, as alloca isn't used. (alloca, __alloca): Likewise. [!_LIBC]: Include "getcwd.h", "mempcpy.h". Include , , , unconditionally, as gnulib assumes C89 or better. Do not include . (errno) [!defined __GNU_LIBRARY__ && !defined STDC_HEADERS]: Remove no-longer-necessary 'extern int errno' decl; gnulib assumes C89 or better. (NULL) [!defined NULL]: Remove; we assume C89 or better. Include in a way that is compatible with modern Autoconf. (_D_ALLOC_NAMELEN, _D_EXACT_NAMLEN): New macros, if not already defined. Include if _LIBC, not if __GNU_LIBRARY__. Use "_LIBC", not "defined _LIBC", for consistency. (HAVE_MEMPCPY): Remove; no longer needed now that gnulib has a mempcpy module. (__lstat, __closedir, __opendir, __readdir) [!_LIBC]: New macros. (GETCWD_RETURN_TYPE): Remove. All uses replaced by char *. * lib/xgetcwd.c: David MacKenzie's old code was removed, so give credit only to Jim Meyering and adjust the copyright dates. Do not include , , , , , "pathmax.h". Instead, include "xgetcwd.h" (first) and "getcwd.h". (INITIAL_BUFFER_SIZE): Remove. (xgetcwd): Rely on getcwd, since we now depend on a reliable one. 2004-11-25 Paul Eggert * m4/getcwd-path-max.m4 (gl_FUNC_GETCWD_PATH_MAX): Renamed from GL_FUNC_GETCWD_PATH_MAX for consistency. All uses changed. Use the _ONCE methods, for efficiency. Check for fcntl.h. In test program, include and if available. Remove old K&R cruft from test program. Check for common errors in GNU/Linux, OpenBSD, and Solaris. Just set gl_cv_func_getcwd_path_max; don't do AC_LIBOBJ, as that's getcwd.m4's job. * m4/getcwd.m4 (gl_FUNC_GETCWD_NULL): Renamed from AC_FUNC_GETCWD_NULL. All used changed. Change cache variable name accordingly. (gl_FUNC_GETCWD, gl_PREREQ_GETCWD): New macros. Revamp to accommodate new getcwd.c. * m4/jm-macros.m4 (gl_MACROS): Don't require GL_FUNC_GETCWD_PATH_MAX. * m4/prereq.m4 (gl_PREREQ): Add gl_FUNC_MEMPCPY. * m4/xgetcwd.m4 (gl_XGETCWD): Replace with gl_FUNC_GETCWD, since that's all we need now. 2004-11-23 Sergey Poznyakoff * m4/argp.m4 (gl_ARGP): Require gl_GETOPT_SUBSTITUTE unconditionally: argp-parse.c depends on getopt internals, that means we should always use our getopt, to be on the safe side. * m4/getopt.m4 (gl_GETOPT): Check if GETOPT_H is already set, in order not to spoil the result of an eventual previous invocation of gl_GETOPT_SUBSTITUTE. 2004-11-23 Sergey Poznyakoff * lib/getopt_.h: Re-addition of __getopt_argv_const caused redefinition warnings. To avoid them, include the defines in `#if !defined __need_getopt ... #endif'. The only place where __getopt_argv_const is used is in definitions of getopt_long and getopt_long_only below, which are as well protected by `#ifndef __need_getopt'. [defined __GETOPT_PREFIX && !defined __need_getopt]: Undef __need_getopt after including and These headers might have defined it. 2004-11-23 Paul Eggert * m4/utimens.m4 (gl_UTIMENS): Check for futimes function. 2004-11-23 Paul Eggert * lib/utimens.c (__attribute__, ATTRIBUTE_UNUSED): New macros. (futimens): New function, which uses futimes if available. (futimens, utimens): Support timespec==NULL, with same semantics as utime and utimens. * lib/utimens.h (futimens): New decl. 2004-11-23 Jim Meyering * lib/getopt_.h: Remove trailing blanks. 2004-11-23 Jim Meyering * lib/__fpending.c: Add comment. 2004-11-22 Paul Eggert * modules/canonicalize (Depends-on): Add xreadlink. Problem reported by James Youngman. 2004-11-20 Paul Eggert * lib/getopt_.h (__GETOPT_CONCAT, __GETOPT_XCONCAT, __GETOPT_ID): New macros. (getopt, getopt_long, getopt_long_only, optarg, opterr, optind, optopt): Use them instead of invoking ## directly; otherwise, the symbols will be __GETOPT_PREFIXgetopt rather than rpl_getopt. 2004-11-19 Bruno Haible * lib/strtok_r.c: Move comments from here... * lib/strtok_r.h: ... to here. 2004-11-17 Paul Eggert * m4/calloc.m4 (_AC_FUNC_CALLOC_IF): Check for buggy calloc implementations that mishandle size_t overflow. 2004-11-17 Paul Eggert * lib/realloc.c (rpl_realloc): Call 'free' if n==0, since realloc might fail. Problem reported by Yoann Vandoorselaere. * lib/calloc.c (rpl_calloc): Defend against buggy calloc implementations that mishandle size_t overflow. 2004-11-16 Paul Eggert * modules/canon-host (Depends-on): Add strdup. 2004-11-16 Paul Eggert * m4/canon-host.m4 (gl_CANON_HOST): Check for getaddrinfo. 2004-11-16 Paul Eggert * lib/canon-host.c: Include "strdup.h". (canon_host): Use getaddrinfo if available, so that IPv6 works. Use strdup instead of malloc/strcpy to duplicate strings. * lib/human.h (LONGEST_HUMAN_READABLE): Add 1 for space before unit. (human_space_before_unit): New constant. * lib/human.c (human_readable): Support it. * lib/xgetcwd.c: Include , for PATH_MAX. (xgetcwd): Set errno correctly when failing. Work around Solaris 9 bug: getcwd sets errno==ERANGE even though the failure is actually due to a PATH_MAX problem. Further getopt changes to make it more likely that glibc will buy the changes back. * lib/getopt.c (POSIXLY_CORRECT): New constant. (getopt): Use it, so to preserve glibc semantic * lib/getopt1.c (getopt_long, getopt_long_only): Arg is char * const * when compiling for libc. * lib/getopt_.h (__getopt_argv_const): Bring it back. (getopt_long, getopt_long_only): Use it. * lib/getopt.c (_getopt_initialize, _getopt_internal_r, _getopt_internal): New arg POSIXLY_CORRECT. All callers changed. (getopt): Argv is now char * const *, as per standard. (_getopt_internal_r, _getopt_internal): Argv is now char **, not char *__getopt_argv_const *. * lib/getopt1.c (getopt_long, _getopt_long_r, getopt_long_only, _getopt_long_only_r): Likewise. * lib/getopt_.h (getopt, getopt_long, geopt_long_only): Likewise. * lib/getopt_int.h (_getopt_internal, _getopt_internal_r, _getopt_long_r, _getopt_long_only_r): Likewise. * lib/getopt_.h (__getopt_argv_const): Remove. (getopt): Argv is now char * const *, as per standard. * lib/getdate.y (tORDINAL): New token. (day, relunit): Allow it for relative times. (relative_time_table): Use tORDINAL for ordinals. 2004-11-16 Paul Eggert * doc/getdate.texi (General date syntax): "next" is 1, not 2. Document that "second" isn't allowed as an ordinal number. 2004-11-16 Jim Meyering * modules/closeout (Depends-on): Add fpending. 2004-11-15 Jim Meyering * lib/closeout.c: Include "__fpending.h" once again. Include . (close_stdout): Don't fail just because stdout was closed initially, since some programs don't write to stdout in the normal course of operation (other than --version and --help), and we don't want this function to make e.g. `touch file >&-' fail. But do fail if it was closed and someone has tried to write to it. E.g., `printf foo >&-' must fail. 2004-11-13 Jim Meyering * m4/jm-macros.m4: Do require gl_FUNC_FPENDING. 2004-11-12 Simon Josefsson * config/srclist.txt: Add strtok_r.c, glibc bought our changes, but a small doc fix is still pending. 2004-11-11 Simon Josefsson * modules/strtok_r: New file. * MODULES.html.sh (Support for systems lacking POSIX:2001): Add strtok_r. 2004-11-11 Simon Josefsson * m4/strtok_r.m4: New file. * m4/getopt.m4: Replace opterr. 2004-11-11 Simon Josefsson * lib/strtok_r.h, strtok_r.c: New file. 2004-11-11 Paul Eggert * m4/getopt.m4 (gl_GETOPT_SUBSTITUTE): Define __GETOPT_PREFIX instead of replacing opterr, getopt, etc. This should handle the powerpc-apple-darwin5.5 problem recently noted by Simon Josefsson. 2004-11-11 Paul Eggert * lib/getopt_.h (__getopt_argv_const): New macro, to be used so that we can stop lying to compilers about the constness of argv when we are compiled outside glibc. (getopt, getopt_long, getopt_long_only): Use it. * lib/getopt.c (_getopt_initialize, _getopt_internal_r, _getopt_internal, getopt): Likewise. * lib/getopt1.c (getopt_long, _getopt_long_r, getopt_long_only, _getopt_long_only_r): Likewise. * lib/getopt_int.h (_getopt_internal, _getopt_internal_r, _getopt_long_r, _getopt_long_only_r): Likewise. * lib/getopt_.h [defined __GETOPT_PREFIX && !defined __need_getopt]: Include and , and if available. Then rename getopt to __GETOPT_PREFIX##getopt, and so forth for the other external symbols. (getopt) [!defined __GNU_LIBRARY]: Use prototype, not old-style declaration, since the above renaming now works around collisions. 2004-11-11 Jim Meyering * lib/linebreak.c: Remove trailing blanks. * lib/alloca_.h: Likewise. * lib/acosl.c: Likewise. * lib/euidaccess.c: Likewise. * lib/allocsa.h: Likewise. 2004-11-10 Simon Josefsson * m4/getaddrinfo.m4: New file. 2004-11-10 Simon Josefsson * lib/getaddrinfo.h, lib/getaddrinfo.c: New files. 2004-11-10 Simon Josefsson * MODULES.html.sh (Support for systems lacking POSIX:2001): Add getaddrinfo. * modules/getaddrinfo: New file. 2004-11-10 Paul Eggert * m4/prereq.m4 (gl_PREREQ): Require gt_FUNC_SETENV. 2004-11-10 Paul Eggert * lib/mktime.c (SHR): New macro, which is a portable substitute for >> that should work even on Crays. (TIME_T_MIDPOINT, ydhms_diff, __mktime_internal): Use it. Problem reported by Mark D. Baushke in . * lib/getdate.y (SHR): Likewise. (tm_diff): Use it. * lib/strftime.c (SHR): Likewise. (tm_diff): Use it. * lib/quotearg.c (struct quoting_options): Use unsigned int for quote_these_too, so that right shifts are well defined. All uses changed. 2004-11-10 Jim Meyering Ensure that no close failure goes unreported. * lib/closeout.c (close_stdout): Always close stdout. I.e., don't return early when it seems there's nothing to flush. Don't include __fpending.h. 2004-11-10 Jim Meyering * modules/closeout (Depends-on): Remove fpending. 2004-11-10 Jim Meyering * m4/jm-macros.m4 (gl_MACROS): Don't require gl_FUNC_FPENDING. 2004-11-09 Paul Eggert * m4/strftime.m4 (_gl_STRFTIME_PREREQS): Remove. Move its body to gl_FUNC_STRFTIME. (gl_FUNC_STRFTIME): Use AC_CHECK_FUNCS_ONCE and AC_CHECK_HEADERS_ONCE and AC_REQUIRE when possible, to avoid duplicate checks. Check for . 2004-11-09 Paul Eggert * lib/strftime.c (DO_MULTIBYTE): Check for wchar.h, too. 2004-11-09 Bruno Haible * m4/sockpfaf.m4: New file. 2004-11-05 Bruno Haible * lib/readlink.c: Include stddef.h, needed for size_t on Woe32. Reported by Mark D. Baushke . 2004-11-04 Bruno Haible 2004-09-11 Bruno Haible * allocsa.valgrind: New file. 2004-02-06 Bruno Haible * allocsa.h (sa_alignof): Define differently with HP-UX cc, to avoid a bug of this cc on HP-UX 10.20 dealing with enums. Reported by Christopher Seip . 2004-11-04 Bruno Haible * modules/allocsa (Files): Add lib/allocsa.valgrind. (Makefile.am): Distribute it. 2004-11-03 Paul Eggert * lib/xreadlink.c (xreadlink): AIX and HP-UX readlink return -1 with errno == ERANGE if the buffer is too small. Problem reported by Mark D. Baushke. 2004-11-03 Albert Chin Paul Eggert * m4/uint32_t.m4 (gl_AC_TYPE_UINT32_T): When determining uint32_t equivalent, substitute $ac_type for equivalent type rather than blindly using uint32_t *always* which won't work if uint32_t is not available. Define _UINT32_T to work around typedef of uint32_t if , , or used on Solaris 2.5.1. 2004-11-02 Paul Eggert * m4/jm-macros.m4: Sync from coreutils. (gl_MACROS): Check for mbrlen, for pathchk. (gl_CHECK_ALL_TYPES): Require AC_TYPE_MBSTATE_T, for pathchk. 2004-11-02 Paul Eggert * lib/xreadlink.c (MAXSIZE): New macro. (xreadlink): Use it instead of SSIZE_MAX. Ensure initial buffer size does not exceed MAXSIZE. Avoid cast. As suggested by Mark D. Baushke in , if readlink fails with buffer size just under MAXSIZE, try again with MAXSIZE. 2004-11-02 Paul Eggert * config/srclist.txt: Add mktime.c; glibc bought all our changes. 2004-11-02 Derek R. Price and Paul Eggert * lib/getdate.y [!TEST]: Include , since we use sprintf now.

(Depends-on): Add setenv, xalloc. 2004-10-29 Paul Eggert * lib/getdate.y: Add support for TZ="foo" within a date string. Fix some bugs near time_t boundaries. Reject dates with out-of-range components, e.g., "Sept 31". Include , "setenv.h", "xalloc.h". (ISDIGIT_LOCALE): Remove; unused. Note that the TZ and time functions used here are not reentrant. (mktime_ok, get_tz): New functions. (TZBUFSIZE): New constant. (get_date): Parse leading TZ="foo". Reject out-of-range components;. This requires that we sometimes generate our own TZ="XXX..." setting. 2004-10-29 Paul Eggert * doc/getdate.texi: New file, from coreutils with modifications for the new TZ parsing. 2004-10-27 Derek R. Price * lib/mktime.c (not_equal_tm): Remove redundant check. 2004-10-24 Paul Eggert * modules/regex (lib_SOURCES): Add regex.c. Reported by James Youngman in . 2004-10-24 Paul Eggert * lib/getdate.y: Use Bison 1.875 features, and some minor code cleanups. This change does not affect semantics. Don't include ; no longer needed. Don't include unlocked-io.h; only the "#if TEST" code uses stdio, and performance isn't crucial there. (PC, YYLEX_PARAM, YYPARSE_PARAM): Remove; replaced by Bison 1.875 features as described below. All uses of "PC." replaced by "pc->". (YYSTYPE): Add a forward declaration. (yylex, yyerror): Use full prototypes in forward decls. Use "%pure-parser" rather than obsolescent "%pure_parser". Use %parse-param and %lex-param instead of obsolescent YYPARSE_PARAM and YYLEX_PARAM. (meridian_table, month_and_day_table, time_units_table, relative_time_table, time_zone_table, military_table, lookup_zone, lookup_word, get_date): Use NULL instead of 0 where appropriate. (to_hour): Avoid abort (), to avoid a dependency on stdlib.h. (yyerror, yylex): Now accepts parser_control * arg. (main) [TEST]: Use '\0' rather than 0 for char. 2004-10-22 Paul Eggert * m4/getpagesize.m4 (gl_GETPAGESIZE): Check for . 2004-10-22 Paul Eggert * lib/getpagesize.c (getpagesize): Don't assume exists. It's now the caller's responsibility to handle the case where !HAVE_GETPAGESIZE && !defined getpagesize. * lib/mktime.c (leapyear): Arg is long int, not int. 2004-10-18 Paul Eggert * lib/argp-fs-xinl.c, argp-xinl.c: Update from glibc. 2004-10-17 Paul Eggert * gnulib-tool (func_emit_lib_Makefile_am): Fix typo: a $ was missing. Problem reported by James Youngman. 2004-10-16 Simon Josefsson * gnulib-tool: Fix comments. Fix parse problem. (func_emit_lib_Makefile_am): Don't hard code a in libgl_a_SOURCES. 2004-10-15 Paul Eggert * m4/getopt.m4 (gl_GETOPT): Detect and reject the incompatible BSD implementation of getopt_long. Problem reported by Alexander Taler in: http://lists.gnu.org/r/bug-gnulib/2004-10/msg00103.html 2004-10-15 Bruno Haible * gnulib-tool: Untabify. Initialize supplied_libname. (func_usage): More homogenous output. (func_modules_transitive_closure, func_modules_to_filelist, func_emit_lib_Makefile_am): New functions. (func_import): New function, extracted from big case statement. Use func_get_license, func_modules_transitive_closure, func_modules_to_filelist, func_emit_lib_Makefile_am. Initialize opt_lgpl.

Also, fix a typo in a diagnostic. 2004-05-30 Paul Eggert * m4/xalloc.m4 (gl_PREREQ_XMALLOC): Do not require AC_FUNC_MALLOC or AC_FUNC_REALLOC. 2004-05-30 Paul Eggert * modules/hash (Depends-on): Remove malloc, realloc. * modules/xalloc (Depends-on): Likewise. * README: Mention that the 'free' module works around the problem with 'free (0)'. Mention LIA-1 and C99. Add a copyright notice. * lib/xmalloc.c (HAVE_MALLOC, HAVE_REALLOC): Do not require these macros to be defined. (xnmalloc_inline, xnrealloc_inline, xcalloc): Do not die if the allocator returns NULL because the requested size is zero. 2004-05-20 Paul Eggert * lib/malloc/obstack.c (_obstack) [defined _LIBC]: Bring back this var. Add comment explaining why libc still defines it. This merges the following patch from glibc: http://sources.redhat.com/ml/libc-alpha/2004-05/msg00157.html 2004-05-20 Andreas Schwab * m4/free.m4: Replace free if it not known to work, not the other way round. 2004-05-19 Paul Eggert * lib/obstack.c (_obstack): Remove unused variable. It hasn't been present in glibc since revision 1.1 of this file. * lib/obstack.h (_obstack_free, obstack_1grow, obstack_1grow_fast, obstack_alignment_mask, obstack_alloc, obstack_base, obstack_blank, obstack_blank_fast, obstack_chunk_size, obstack_copy, obstack_copy0, obstack_finish, obstack_grow, obstack_grow0, obstack_init, obstack_int_grow, obstack_int_grow_fast, obstack_make_room, obstack_memory_used, obstack_next_free, obstack_object_size, obstack_ptr_grow, obstack_ptr_grow_fast, obstack_room): Remove declarations of nonexistent functions. 2004-05-18 Karl Berry * config/srclist.txt: break link for vasnprintf.c. 2004-05-17 Paul Eggert Port obstack to the AS/400, where pointers are 16 bytes wide and you cannot cast an integer to a valid pointer. This patch is currently waiting to be integrated into glibc; see . * lib/obstack.h (__PTR_TO_INT, __INT_TO_PTR): Remove. All uses of __INT_TO_PTR (PTR_TO_INT ...) replaced by __PTR_ALIGN. (__BPTR_ALIGN, __PTR_ALIGN): New macros. (struct obstack): temp member is now a union of a pointer and an integer, instead of an integer. All integer uses changed. This does not affect the physical layout of struct obstack, except on hosts (like the AS/400) where the size or alignment of void * is greater than that of ptrdiff_t. (obstack_finish) [! (defined __GNUC__ && defined __STDC__ && __STDC__)]: Store temporary in pointer member of union, not integer member. * lib/obstack.c: Include , for offsetof. (struct fooalign): Remove; it doesn't need a name. (union fooround): Change double to long double, and add void *. (DEFAULT_ALIGNMENT): Use offsetof to compute. (DEFAULT_ALIGNMENT, DEFAULT_ROUNDING): Now an enum constant, not a macro. Hence the values are always int; so remove all casts-to-int in uses. 2004-05-17 Paul Eggert * config/srclist.txt: Break link for argp-help.c and argp-parse.c until we can get this patch merged into glibc. 2004-05-17 Derek R. Price Paul Eggert * m4/argp: Depend on alloca. 2004-05-17 Derek R. Price Paul Eggert * lib/argp-help.c, argp-parse.c: Assume rather than freecoding. 2004-05-17 Bruno Haible * lib/vasnprintf.c (VASNPRINTF): Correctly handle the case of a precision that consists of a '.' followed by an empty digit string. Patch by Tor Lillqvist . 2004-05-16 Paul Eggert * modules/getdate: Depend on alloca. * modules/setenv: Likewise. 2004-05-16 Paul Eggert * m4/alloca.m4 (gl_FUNC_ALLOCA): Define HAVE_ALLOCA_H always, for backward compatibility with older code. We need our own alloca.h if _AIX is defined. Define HAVE_ALLOCA if we discover it under some other name, and our alloca.h will define it. 2004-05-16 Paul Eggert Derek Price * lib/alloca.c: Include , to get our interface. * lib/alloca_.h: Use __alloca on AIX, so that we don't have to include first. Use C89 prototype for alloca; this requires including for size_t. Use extern "C" if C++. Use #elif for simplicity, since we can assume C89 now. Don't try to source the system alloca.h since it will not be found and to prevent recursively including its replacement. * lib/fnmatch.c: Include instead of opencoding. * lib/regex.c: Likewise. 2004-05-16 Derek Price Paul Eggert getline cleanup. This changes the getndelim2 API: both order of arguments, and meaning of delim2 (now uses EOF, not 0, to indicate no delimiter). * lib/getline.c: Don't include stddef.h or stdio.h, since our interface does that. (getline): Always use getdelim, so that we don't have two copies of this code. * lib/getndelim2.c: Include , , if available. (PTRDIFF_MAX, SIZE_MAX, SSIZE_MAX): Define if not defined. (GETNDELIM2_MAXIMUM): New macro. (getndelim2): Reorder arguments. delim==EOF now means no delimiter, instead of the old practice of delim2==0. All callers changed. Return -1 on overflow, instead of returning junk. Do not set *linesize unless allocation succeeds. * lib/getndelim2.h: Do not include stddef.h; no longer needed, now that we include sys/types.h. * lib/getnline.h: Likewise. * lib/getndelim2.h (GETNLINE_NO_LIMIT): New macro. (getndelim2): Reorder arguments. * lib/getnline.c (getnline, getndelim): Don't discard the NMAX argument. (getnline): Invoke getndelim, to avoid code duplication. * lib/getnline.h (GETNLINE_NO_LIMIT): New macro, used instead of (size_t) -1 by callers of the getnline family. 2004-05-13 Paul Eggert * m4/gettime.m4 (gl_GETTIME): Require gl_TIMESPEC. Check for gettimeofday. * m4/settime.m4 (gl_SETTIME): Require gl_TIMESPEC. Check for settimeofday, stime. 2004-05-13 Paul Eggert * lib/nanosleep.c (suspended): Change its type from int to sig_atomic_t volatile. (first_call): Make it private to rpl_nanosleep, and have it be zero initially as that's a bit faster. (my_usleep): Round up fractional times instead of truncating them, as this is the usual meaning for 'sleep'. * lib/gettime.c (gettime): Fall back on `time' if `gettimeofday' doesn't work. * lib/settime.c: Include , for stime (on Solaris 8, anyway). (ENOSYS): Define if not defined. (settime): Fall back on stime if it exists and settimeofday fails. But don't bother with fallbacks if a method fails with errno == EPERM. 2004-05-11 Jim Meyering Prior to this change, the save_cwd caller required read access to the current directory on most systems (ones with the fchdir function). * lib/save-cwd.c (save_cwd) [HAVE_FCHDIR]: If opening `.' read-only fails, try write-only, and finally, resort to using xgetcwd. 2004-05-06 Paul Eggert * lib/obstack.c, obstack.h: Import changes from libc. 2004-05-04 Derek Price * modules/argp: Remove dependency on alloca. 2004-04-28 Bruno Haible * lib/findprog.c (find_in_path): Treat Cygwin like Windows, since it also implicitly appends .exe to executables. * lib/localcharset.c (ISSLASH): Treat Cygwin like Windows, since it now accepts Windows pathnames. * lib/pathname.h (ISSLASH, IS_PATH_WITH_DIR, FILESYSTEM_PREFIX_LEN): Treat Cygwin like Windows, since it now accepts Windows pathnames. * lib/progreloc.c (ISSLASH, IS_PATH_WITH_DIR, FILESYSTEM_PREFIX_LEN): Treat Cygwin like Windows, since it now accepts Windows pathnames. Reported by Derek Robert Price . 2004-04-27 Derek Price * m4/dos.m4 (gl_AC_DOS): Add Cygwin to list of Windows/DOS environments that accept backslashes and drive letters in paths. 2004-04-21 Karl Berry * config/srclist.txt (localcharset.c): break sync. 2004-04-20 Paul Eggert * m4/host-os.m4: Add a copyright notice. 2004-04-20 Jim Meyering * modules/dirfd: Change UTILS_ macro name prefix to gl_. * modules/mkstemp: Likewise. * modules/mkdir: Likewise.

Add intmax.m4, printf-posix.m4, sig_atomic_t.m4, signalblocking.m4, ssize_t.m4. * lib/unsetenv.c: Regenerate: this subtracts 1 from the copyright year (!). * m4/printf-posix.m4: Regenerate. * modules/inttostr (EXTRA_DIST): Move inttostr.c here.... (lib_SOURCES): from here. * modules/getopt (lib_SOURCES): Add getopt_int.h. 2004-04-12 Jim Meyering * MODULES.html.sh (func_all_modules): Add cloexec, inttostr, free, tzset. 2004-04-11 Paul Eggert * lib/inttostr.h: Include unconditionally, since we assume C89. (CHAR_BIT): Remove, since we assume C89. Include if available, as per current Autoconf CVS advice. 2004-03-31 Jim Meyering * m4/prereq.m4: Require AC_FUNC_MALLOC, not jm_FUNC_MALLOC.

(get_date): Change signature to support fractional time stamps. All callers changed. * lib/getdate.y: Include "getdate.h" first, as we can now assume C89 and don't need to worry about 'const'. Similarly, include "unlocked-io.h" near start, not in middle. Include . (textint.value): Use long int rather than int. (textint.digits): Use size_t rather than int. (BILLION, LOG10_BILLION): New constants. (parser_control): New member rel_ns. Members day_ordinal, time_zone, month, day, hour, minutes, rel_year, rel_month, rel_day, rel_hour, rel_minutes, rel_seconds are now long int, not int. Member seconds is now struct timespec, not int. New member timespec_seen. Members dates_seen, days_seen, local_zones_seen, rels_seen, times_seen, zones_seen are now size_t, not int. (%union.intval): Now long int, not int. New member timespec.

(gmtime, localtime, mktime): Remove decls; not needed with C89. (to_hour): First arg is now long int, not int. (to_year): Returns long int, not int. Don't treat year -70 like 70. (tm_diff): Returns long int, not int. (lookup_word): Use bool instead of int when appropriate. (yylex): Use size_t for count, not int. Detect overflow when parsing large integer constants. Add support for fractions. (get_date): Make pointers 'const' if possible. Use more-portable code to detect integer overflow. (main) [TEST]: Adjust to above changes. Test for localtime failure. Don't use ctime; it's not reliable if the year has >4 digits. * lib/human.c (humblock): Inspect BLOCKSIZE if BLOCK_SIZE isn't set. This is for compatibility with BSD. * lib/timespec.h (ST_TIME_CMP_NS, ST_TIME_CMP): Define. (ATIME_CMP, CTIME_CMP, MTIME_CMP, TIMESPEC_NS): Likewise. From coreutils' system.h. * lib/userspec.c: Don't include "posixver.h". (parse_user_spec): Fall back on USER.GROUP parsing, regardless of POSIX version, as POSIX 1003.1-2001 allows that behavior as a compatible extension. Simplify code by removing a boolean int that was always nonzero if a string was nonnull. 2004-03-30 Jim Meyering Merge from coreutils. Avoid a configure-time warning about sys/ucred.h on OSF V4.0. * m4/ls-mntd-fs.m4: Test for sys/ucred.h separately, since on some systems one must include before it. Reported by Christian Krackowizer. 2004-03-30 Jim Meyering Merge from coreutils. * lib/mountlist.c [HAVE_SYS_UCRED_H]: Include grp.h before sys/ucred.h. * lib/readtokens.c (readtoken): Don't leak 64 bytes when reading an empty input stream. * lib/readtokens.c: Include . (readtoken): Use `size_t' rather than int/long. All callers adjusted. Use `bool' rather than `int' where appropriate. Use memset rather than an explicit loop. Use x2nrealloc rather than xrealloc. Allow the use of `\0' as a delimiter. (readtokens): Likewise. * lib/readtokens.h (readtoken, readtokens): Update prototypes. 2004-03-30 Jim Meyering * modules/realloc (Files): Remove m4/realloc.m4. (configure.ac): Depend on AC_FUNC_REALLOC, rather than jm_FUNC_REALLOC. * modules/malloc (Files): Remove m4/malloc.m4. (configure.ac): Depend on AC_FUNC_MALLOC, rather than jm_FUNC_MALLOC. * m4/realloc.m4: Remove file, since now it does no more than AC_REQUIRE([AC_FUNC_REALLOC]), and that can be done via the `configure.ac' section of module/realloc. * m4/malloc.m4: Likewise, but for AC_FUNC_MALLOC. 2004-03-30 Bruno Haible * lib/getloadavg.c (getloadavg): Don't assume setlocale returns nonnull. 2004-03-29 Paul Eggert Merge changes to getloadavg.c from coreutils and Emacs. * modules/getloadvg: Depend on cloexec and xalloc. * lib/getloadavg.c [!defined HAVE_SETLOCALE] (setlocale): Define to an expression, not to the empty string.

Check alloca, malloc, realloc, ENSURE_ALLOCATION arguments against overflow. Avoid wraparound when converting a width or precision from decimal to binary. 2003-11-16 Bruno Haible Update from GNU gettext. * lib/printf-parse.c: Generalize to it can be compiled for wide strings. (PRINTF_PARSE, CHAR_T, DIRECTIVE, DIRECTIVES): New macros. * lib/vasnprintf.c: Generalize to it can be compiled for wide strings. (VASNPRINTF, CHAR_T, DIRECTIVE, DIRECTIVES, PRINTF_PARSE, USE_SNPRINTF, SNPRINTF): New macros. Don't include if the file is used inside libintl. (local_wcslen): New function, for Solaris 2.5.1.

(xsum, xsum3, xsum4): Declare as "pure" functions. 2003-11-12 Paul Eggert * modules/xalloc (Files): Undo latest change, since xalloc.h no longer needs SIZE_MAX or PTRDIFF_MAX. 2003-11-12 Paul Eggert * m4/xalloc.m4 (gl_PREREQ_XALLOC): Do not require gl_SIZE_MAX or gl_PTRDIFF_MAX. 2003-11-12 Paul Eggert * lib/xstrtol.c (__xstrtol): Remove "break" immediately after "return", to pacify some unknown compiler. Problem reported by Joerg Schilling. 2003-11-12 Paul Eggert * lib/xalloc.h: Do not include or . (xalloc_oversized): Use sizeof (ptrdiff_t) and sizeof (size_t) for the heuristic, rather than PTRDIFF_MAX and SIZE_MAX.

Assume SIZE_MAX and PTRDIFF_MAX are defined. 2003-11-10 Paul Eggert * lib/xalloc.h (xalloc_oversized): [! (defined PTRDIFF_MAX && PTRDIFF_MAX < SIZE_MAX)]: Fix off-by-one error that would have rejected some allocations of exactly SIZE_MAX - 2 bytes. From Bruno Haible. [defined PTRDIFF_MAX && PTRDIFF_MAX < SIZE_MAX]: Use SIZE_MAX, not (size_t) -1, since it's defined here. 2003-11-09 Karl Berry * config/mkinstalldirs, depcomp, mdate-sh: update from automake. 2003-11-06 Paul Eggert * lib/xalloc.h [HAVE_STDINT_H]: Include . (xalloc_oversized) [! (PTRDIFF_MAX < SIZE_MAX)]: Reject sizes of exactly SIZE_MAX bytes. * lib/xreadlink.c: Include "xalloc.h" before checking whether SIZE_MAX is defined, since "xalloc.h" now defines SIZE_MAX on modern hosts. 2003-11-05 Bruno Haible * lib/xsize.h: Include limits.h, to avoid a possible collision with SIZE_MAX defined in on Solaris. 2003-11-04 Jim Meyering * modules/sysexits: Use the `$(VAR)' notation for AC_SUBST'd variable names, rather than @VAR@. * modules/poll: Likewise. 2003-11-04 Bruno Haible * modules/xsize: New file. * modules/linebreak: Depend on xsize. * MODULES.html.sh (func_all_modules): Add xsize. 2003-11-04 Bruno Haible * m4/xsize.m4: New file. 2003-11-04 Bruno Haible * lib/xsize.h: New file. * lib/linebreak.c: Include xsize.h.

Suggested by Paul Eggert. 2003-11-02 Karl Berry * config/srclist.txt (vasprintf.c): sync broken, sigh. 2003-10-31 Paul Eggert * lib/mountlist.h (struct mount_entry.me_type_malloced): New member. * lib/mountlist.c (SIZE_MAX): Define if not defined already. (read_filesystem_list): Set and use me_type_malloced. Use "sizeof *me" rather than "sizeof (struct mount_entry)" (or whatever the type happens to be), for brevity and consistency. Check for size calculation overflow on Alphas running OSF/1. 2003-10-31 Jim Meyering * lib/hash.c: Include "xalloc.h" for use of xalloc_oversized. * lib/linebuffer.c: Include for declaration of memset. 2003-10-30 Paul Eggert Bruno Haible * lib/vasprintf.c: Include , . (vasprintf): Fail if the resulting length doesn't fit in an 'int'. 2003-10-30 Paul Eggert * m4/host-os.m4 (UTILS_HOST_OS): Change netbsd*-gnu pattern back to netbsd*-gnu*. Suggested by Robert Millan. 2003-10-29 Paul Eggert * modules/group-member: Depend on stdbool. 2003-10-29 Paul Eggert * m4/xalloc.m4 (gl_XALLOC): Undo previous change. 2003-10-29 Paul Eggert * m4/host-os.m4 (UTILS_HOST_OS): Resurrect netbsd*-gnu. Add comments to it, and to knetbsd*-gnu and kfreebsd*-gnu. Remove the '*' from after the 'gnu' in these cases. This fixes some bugs in the previous change, and is based on suggestions by Robert Millan. 2003-10-29 Paul Eggert * lib/xalloc.h (xalloc_oversized): Now a macro, not a function, so that it works even if SIZE_MAX < N. Do not include ; no longer needed. * lib/quotearg.c (quotearg_n_options): Use it. * lib/group-member.c: Include . (free_group_info): Arg is now const *; don't free arg.

Check for overflow in internal size calculation. * lib/getusershell.c (readname): Simplify the code by using x2nrealloc rather than xmalloc/xrealloc. * lib/linebuffer.c (initbuffer, readlinebuffer): Simplify the code by using x2realloc rather than xmalloc/xrealloc. Also, fix a C conformance bug: the old code used a pointer after freeing the storage that it addressed. * lib/hash.c (hash_initialize): Simplify the code by using xalloc_oversized rather than doing it by hand. * lib/getgroups.c (getgroups): Don't use xrealloc, since we don't need the buffer preserved. Use free and xmalloc instead. * lib/quotearg.c (quotearg_n_options): Likewise. Use a simpler test for size overflow. Don't use xalloc_oversized because unsigned int might be wider than size_t (!); this suggests that we should switch from unsigned int to size_t for slot numbers. 2003-10-28 Paul Eggert * m4/host-os.m4 (UTILS_HOST_OS): Identify GNU/KFreeBSD and GNU/KNetBSD. These implementations use glibc atop the FreeBSD and NetBSD kernels. Requested by Richard Stallman. 2003-10-27 Paul Eggert * lib/exclude.c (new_exclude): Use xzalloc rather than xmalloc to allocate the returned structure. Do not allocate a subarray, as x2nrealloc will do that. (add_exclude): Use x2nrealloc to reallocate ex->exclude, instead of xnrealloc. (add_exclude_file): Use x2realloc instead of malloc + xnrealloc. 2003-10-27 Bruno Haible * lib/stdbool_.h: Better support for BeOS. 2003-10-26 Paul Eggert * m4/xalloc.m4 (gl_XALLOC): Requore AC_C_INLINE, since xalloc.h now uses inline. 2003-10-26 Paul Eggert * lib/xalloc.h (xalloc_oversized): New static inline function, for callers that want to do their own size-overflow checking. Include , since xalloc_oversized returns bool. * lib/xalloc.c (array_size_overflow): Remove. All callers changed to use xalloc_oversized. Add two functions x2realloc, x2nrealloc, for programs that grow arrays dynamically by doubling their sizes. * lib/xalloc.h (x2realloc, x2nrealloc): New decls. * lib/xmalloc.c (x2nrealloc_inline, x2nrealloc, x2realloc): New functions. Port to C99 semantics for 'inline' of external functions. Bug reported by Bruno Haible. * lib/xmalloc.c (xnmalloc_inline): New static inline function, with the old contents of xnmalloc. (xnmalloc, xmalloc): Use it. (xnrealloc_inline): New static inline function, with the old contents of xnrealloc. (xnrealloc, xrealloc): Use it. * lib/alloc.c (alloca): xmalloc cannot return NULL, so don't test for that. 2003-10-26 Karl Berry * config/srclist.txt (COPYING.DOC): no longer available from /gd/gnuorg; don't know where the ultimate source is. 2003-10-25 Paul Eggert Fix several address-calculation bugs in the hash modules, plus some minor code cleanup. * lib/hash.h: Include , for bool. * lib/hash.c: Don't include , since hash.h does it now. * lib/hash.h (Hash_hasher, hash_get_n_buckets, hash_get_n_buckets_used, hash_get_n_entries, hash_get_max_bucket_length, hash_get_entries, hash_do_for_each, hash_string, hash_initialize, hash_rehash): Use size_t rather than unsigned. * lib/hash.c (struct hash_table, hash_get_n_buckets, hash_get_n_buckets_used, hash_get_n_entries, hash_get_max_bucket_length, hash_table_ok, hash_print_statistics, hash_get_entries, hash_do_for_each, hash_string, is_prime, next_prime, hash_initialize, hash_rehash, hash_delete, hash_print): Likewise. (SIZE_MAX): Define if not defined. (hash_get_max_bucket_length, hash_table_ok, hash_lookup, hash_get_first, hash_get_next, hash_get_entries, hash_do_for_each, hash_print): Use const * when possible. (hash_string): Use (unsigned char) *P rather than *(unsigned char *) P. (check_tuning): Fix bug: if tuning parameters were very close to 0 or 1, rounding errors could have caused subscript violations. (hash_initialize, allocate_entry, hash_print): Remove unnecessary cast. (hash_initialize): Add 'fail:' label to free table and return NULL, and use it to simplify code. Use calloc rather than clearing the storage ourself. (hash_initialize, hash_rehash): Check for arithmetic overflow in buffer size calculations. * lib/hash-pjw.h (hash_pjw): Use size_t, not unsigned. Include , for size_t. * lib/hash-pjw.c (hash_pjw): Likewise. Switch to method described by Bruno Haible. Include , for CHAR_BIT. (SIZE_BITS): New macro. 2003-10-23 Paul Eggert * m4/getline.m4 (AM_FUNC_GETLINE): Don't include getndelim2.o twice into LIBOBJS; this breaks on some hosts. Problem reported by Derek Robert Price in . This patch can be withdrawn after Autoconf 2.58 is required for gnulib. * m4/getndelim2.m4 (gl_GETNDELIM2): Likewise. 2003-10-21 Paul Eggert * lib/getndelim2.c (getndelim2): When size calculation overflows, ceiling the allocation at NMAX bytes rather than silently discarding input bytes before NMAX is reached. This makes a difference only if NMAX exceeds SIZE_MAX / 2. * lib/obstack.c: Merge from glibc. [defined _LIBC]: Include , not "obstack.h". Add libc_hidden_def (_obstack_newchunk). (_obstack_free) [! defined _LIBC]: Remove. [defined _LIBC]: Make a strong alias from obstack_free, rather than a clone of the function body. (fputs) [defined _LIBC && defined USE_IN_LIBIO]: Remove. [defined _LIBC && !defined USE_IN_LIBIO]: Include . * lib/obstack.h: Indenting cleanup, to make it easier to merge with glibc. (obstack_grow, obstack_grow0): Remove unnecessary parentheses around arg to memcpy. * lib/obstack.h (obstack_1grow_fast): Properly parenthesize arg. (obstack_ptr_grow_fast, obstack_int_grow_fast): Don't use lvalue casts, as GCC plans to remove support for them in GCC 3.5. Reported by Joseph S. Myers. This bug was also present in the non-GCC version, indicating that this code had always been buggy and had never been widely used. (obstack_1grow, obstack_ptr_grow, obstack_int_grow, obstack_blank): Use the fast variant of each macro, rather than copying the definiens of the fast variant; that way, we'll be more likely to catch future bugs in the fast variants. 2003-10-20 Bruno Haible * modules/wait-process: New file. * MODULES.html.sh (func_all_modules): Add wait-process. 2003-10-20 Bruno Haible * m4/wait-process.m4: New file. 2003-10-20 Bruno Haible * lib/wait-process.h: New file, from GNU gettext. * lib/wait-process.c: New file, from GNU gettext. 2003-10-19 Jim Meyering * lib/vasnprintf.c (vasnprintf): Work around losing snprintf on HPUX 10.20. 2003-10-18 Karl Berry * config/config.guess: update from config. 2003-10-16 Paul Eggert * lib/getgroups.c: Include , . (getgroups): First arg is int, not size_t. Don't let 'free' mangle errno. 2003-10-16 Paul Eggert * README: Mention that gnulib assumes that (foo *) NULL + 0 == NULL. 2003-10-16 Karl Berry * config/config.{guess,sub}: update from config. 2003-10-16 Jim Meyering * lib/xmalloc.c: Include , for declarations of memset and memcpy. 2003-10-15 Paul Eggert * lib/exclude.c: Do not include or . (SIZE_MAX): Remove. (new_exclude, add_exclude_file): Initial size no longer needs to be a power of 2. (add_exclude, add_exclude_file): Use xnrealloc instead of rolling our own address arithmetic overflow checking. * lib/fnmatch.c (SIZE_MAX): Define if standard headers don't. (fnmatch): Do not alloca more than 2000 wide characters; instead, use malloc for large buffers. Check for address arithmetic overflow, and return -1 with errno set to ENOMEM in that case. * lib/fnmatch_loop.c (ALLOCA_LIMIT): New macro. (NEW_PATTERN): Do not alloca more than 8000 bytes; instead, return -1. Check for address arithmetic overflow. 2003-10-14 Paul Eggert Handle invalid suffixes and overflow independently, so that callers can treat them independently as needed. Fix some bugs in suffix handling, e.g., "100k@" was not diagnosed as an invalid suffix for a human-readable blocksize. The major caller-visible change is the addition of a new LONGINT_INVALID_SUFFIX_CHAR_WITH_OVERFLOW enum value, indicating that both overflow and suffix chars were found. * lib/human.c (humblock): Don't check separately for invalid suffix char; that is xstrtoumax's job (now that its bug is fixed). * lib/xstrtoimax.c (STRTOL_T_MINIMUM, STRTOL_T_MAXIMUM) [defined INTMAX_MAX]: New macros. * lib/xstrtol.c (STRTOL_T_MINIMUM, STRTOL_T_MAXIMUM, TYPE_MINIMUM, TYPE_MAXIMUM): New macros. (bkm_scale, bkm_scale_by_power): Return strtol_error, not int. (bkm_scale, bkm_scale_by_power, __xstrtol): Return maximal values if overflow occurs, as it's what __strtol does and it's more useful in practice. (__xstrtol): If __strtol reports some error other than ERANGE, reflect it to the caller as LONGINT_INVALID. If it reports ERANGE, continue the rest of parsing, and report LONGINT_OVERFLOW | LONGINT_INVALID_SUFFIX_CHAR if both errors occur. * lib/xstrtol.h (LONGINT_INVALID_SUFFIX_CHAR_WITH_OVERFLOW): New enum value. (_STRTOL_ERROR): Handle it. Abort when given unknown error codes. * lib/xstrtoul.c (STRTOL_T_MINIMUM, STRTOL_T_MAXIMUM): New macros. * lib/xstrtoumax.c (STRTOL_T_MINIMUM, STRTOL_T_MAXIMUM) [defined UINTMAX_MAX]: New macros. 2003-10-14 Bruno Haible * modules/fatal-signal: Add m4/sig_atomic_t.m4 to file list. 2003-10-14 Bruno Haible * m4/sig_atomic_t: New file, from GNU gettext. * m4/fatal-signal.m4 (gl_FATAL_SIGNAL): Require gt_TYPE_SIG_ATOMIC_T. 2003-10-14 Bruno Haible * lib/fatal-signal.h: Improved comments. Suggested by Paul Eggert. * lib/fatal-signal.c: Use sig_atomic_t. Suggested by Paul Eggert. Also use volatile where needed. 2003-10-12 Paul Eggert * modules/xalloc: Do not depend on 'exit'. Depend on 'stdbool'. Change maintainer from Bruno Haible to 'all'. 2003-10-12 Paul Eggert * m4/xalloc.m4 (gl_PREREQ_XMALLOC): Require AC_C_INLINE. 2003-10-12 Paul Eggert * lib/xalloc.h (xnmalloc, xzalloc, xnrealloc, xclone): New decls. (XMALLOC, XCALLOC, XREALLOC, XFREE, CCLONE, CLONE): Deprecate, and define in terms of the other primitives. * lib/xmalloc.c: Include stdbool.h; do not include exit.h. (SIZE_MAX): Define if not already defined. (array_size_overflow): New function. (xalloc_die): Abort instead of exiting if 'error' returns. (xnmalloc, xnrealloc, xzalloc, xclone): New functions. (xmalloc, xrealloc): Use them. (xcalloc): Check for address arithmetic overflow. * lib/xstrdup.c (xstrdup): Use xclone, since memcpy should be a bit faster than strcpy. 2003-10-10 Simon Josefsson * modules/argp (Depends-on): Add restrict and strcase. 2003-10-10 Simon Josefsson * m4/argp.m4: Add AC_C_INLINE. 2003-10-08 Paul Eggert Merge getpass from libc, plus a few fixes. * lib/getpass.c (HAVE_STDIO_EXT) [_LIBC]: Define to 1. Include . Include if HAVE_STDIO_H, otherwise define __fsetlocking to empty. [_LIBC]: Do not include "getline.h" or "unlocked-io.h", but do include . Do not include ; not needed. [_LIBC]: Include . (NOTCANCEL_MODE): New macro. (flockfile, funlockfile) [_LIBC]: New macros. (__libc_cleanup_push, __libc_cleanup_pop, __getline, __tcgetattr) [!_LIBC]: New macros. (call_fclose): New function. (getpass): Use it. Save tty stream separately; this simplifies the code and makes it more reliable if stdin happens to equal stdout. Invoke __fsetlocking on tty. Handle thread cancellation if needed. Namespace cleanup (use __tcgetattr, __getline). Use bool for Booleans. [USE_IN_LIBIO]: Handle wide streams. [!_LIBC]: Unconditionally do the fseek, since we don't know what stream might go where. * lib/unlocked-io.h: Include , so that the caller doesn't have to include before us. (clearerr_unlocked, feof_unlocked, ferror_unlocked, fflush_unlocked, fgets_unlocked, fputc_unlocked, fputs_unlocked, fread_unlocked, fwrite_unlocked, getc_unlocked, getchar_unlocked, putc_unlocked, putchar_unlocked): Define to the unlocked counterpart if not declared, so that we can use getpass.c code from libc without rewriting it. (flockfile, ftrylockfile, funlockfile): New macros. 2003-10-08 Paul Eggert * modules/getpass: Depend on stdbool. 2003-10-08 Paul Eggert * m4/getpass.m4 (gl_PREREQ_GETPASS): Check for stdio_ext.h. 2003-10-07 Karl Berry * config/config.{guess,sub}: update from config. 2003-10-06 Jim Meyering Bruno Haible This lets translators provide better translations for the "Written by ..." part of --version output. * lib/version-etc.h: Include stdarg.h. (version_etc_copyright): Declare as readonly. (version_etc): Make this function variadic with a NULL-terminated list of author name strings. (version_etc_va): New declaration. * lib/version-etc.c: Include stdarg.h, stdlib.h. (version_etc_copyright): Declare as readonly. (version_etc_va): New function. Provide a different translatable string for each possible number of authors < 10. Abbreviate when there are 10 authors or more. (version_etc): Make this function variadic. Call version_etc_va. Suggestion from Gary V. Vaughan. * lib/long-options.h (parse_long_options): Change prototype: the authors string is moved to the end and becomes variadic. * lib/long-options.c: Include stdarg.h. (parse_long_options): Make this function variadic, too. Call version_etc_va, not version_etc. 2003-10-06 Bruno Haible * modules/version-etc-2: Remove file. * MODULES.html.sh (func_all_modules): Remove version-etc-2. 2003-10-06 Bruno Haible * modules/fatal-signal: New file. * MODULES.html.sh (func_all_modules): Add fatal-signal. 2003-10-06 Bruno Haible * m4/fatal-signal.m4: New file. * m4/signalblocking.m4: New file, from GNU gettext. 2003-10-06 Bruno Haible * lib/version-etc-2.h: Remove file. * lib/version-etc-2.c: Remove file. 2003-10-06 Bruno Haible * lib/fatal-signal.h: New file, from GNU gettext. * lib/fatal-signal.c: New file, from GNU gettext. 2003-10-05 Paul Eggert * README: Rework advice for preventing empty .o files. Don't recommend ELIDE constructs. Recommend , not . 2003-10-04 Karl Berry * lib/argp*: update from libc. 2003-10-04 Karl Berry * config/config.{guess,sub}: update from config. 2003-10-02 Bruno Haible * modules/lchown (Include): Add lchown.h. * modules/time_r (Include): Use "..." syntax. * modules/xgetdomainname (Include): Add xgetdomainname.h. 2003-10-01 Simon Josefsson * MODULES.html.sh (func_all_modules): Move gethostname from section 'based on' to section 'lacking' POSIX:2001. 2003-10-01 Larry Jones * lib/getpass.c (getpass): Use a no-op fseek when switching from input to output mode on the same stream. 2003-09-29 Paul Eggert * lib/strftime.c (tm_diff) [! HAVE_TM_GMTOFF]: Fix arg typo in previous patch. 2003-09-28 Jim Meyering * lib/error.c: Correct cpp indentation. 2003-09-27 Paul Eggert * modules/free: New file. 2003-09-27 Paul Eggert * m4/free.m4: New file. 2003-09-27 Paul Eggert * lib/minmax.h (MIN, MAX) [__STDC__ && defined __GNUC__ && __GNUC__ >= 2]: Omit the special code that used __typeof__, since we worry that it could be more trouble than it's worth. See: http://mail.gnu.org/r/bug-gnulib/2003-01/msg00090.html http://mail.gnu.org/r/bug-gnulib/2003-01/msg00095.html * lib/free.c: New file. 2003-09-27 Oskar Liljeblad Trivial fixes to Makefile.am parts of module listings. * modules/strstr: Append strstr.h to lib_SOURCES. * modules/strcase: Likewise, for strcase.h. 2003-09-27 Karl Berry * config/mkinstalldirs: update from automake. 2003-09-26 Paul Eggert * lib/error.c (SIZE_MAX) [!defined SIZE_MAX]: Define. (error_tail): Do not loop, reallocating temporary buffer, since the output cannot contain more wide characters than the input contains bytes, the size must be big enough already. This avoids one potential size overflow calculation. Check for size overflow when calculating temporary buffer size. Free temporary buffer when done, if it was allocated with malloc; this plugs a memory leak. Remove casts from void * to pointers, that are no longer needed now that we're assuming C89 or better. Merge error changes from glibc. * lib/error.c, error.h: Update copyright notice header to match glibc. * lib/error.c [defined _LIBC]: Include , . (error, error_at_line) [defined _LIBC && defined __libc_ptf_call]: Disable cancellation while printing error. * lib/error.h: Prepend __ to parameter names. 2003-09-26 Jim Meyering * lib/error.c (error_tail): Move some declarations into inner scope where the local variables are used. 2003-09-26 Bruno Haible * m4/stpncpy.m4 (gl_FUNC_STPNCPY): Add comments about the AIX stpncpy(). Don't define stpncpy through config.h; it's now done through stpncpy.h. 2003-09-26 Bruno Haible * lib/stpncpy.h (gnu_stpncpy): New declaration. (stpncpy): Define as alias for gnu_stpncpy. * lib/stpncpy.c [!_LIBC]: Define gnu_stpncpy, not stpncpy. 2003-09-25 Simon Josefsson * lib/xgetdomainname.h: New file. * lib/xgetdomainname.c: New file. 2003-09-25 Simon Josefsson Bruno Haible * modules/getdomainname: New file. * modules/xgetdomainname: New file. * MODULES.html.sh (func_all_modules): Add getdomainname, xgetdomainname. 2003-09-25 Simon Josefsson Bruno Haible * m4/getdomainname.m4: New file. 2003-09-25 Simon Josefsson Bruno Haible * lib/getdomainname.h: New file. * lib/getdomainname.c: New file. 2003-09-25 Karl Berry * lib/argp-fmtstream.c, argp-help.c: update from libc. 2003-09-25 Karl Berry * config/install-sh: update from automake. 2003-09-25 Bruno Haible * modules/version-etc-2: New file, from modules/version-etc with modifications. * MODULES.html.sh (func_all_modules): Add version-etc-2. 2003-09-25 Bruno Haible * lib/version-etc-2.h: New file, from version-etc.h with modifications. * lib/version-etc-2.c: New file, from version-etc.c with modifications. 2003-09-24 Simon Josefsson * modules/xgethostname: Add xgethostname.h. 2003-09-24 Paul Eggert * lib/linebuffer.c (freebuffer): Don't free the argument, just the buffer associated with the argument. Bug reported by Simon Josefsson. 2003-09-24 Paul Eggert * README: Document assumptions that 'int' is at least 32 bits wide, that integer arithmetic is 2's complement without overflow, that there are no holes in integer values, that adding sizes of two nonoverlapping objects can't overflow, and that all-bits-zero yields scalar zero. Fix spelling and capitalization typos. 2003-09-19 Karl Berry * lib/argp.h: update from libc. 2003-09-17 Paul Eggert * m4/extensions.m4 (gl_USE_SYSTEM_EXTENSIONS): Call AC_BEFORE first, to avoid spurious warnings like "AC_RUN_IFELSE was called before gl_USE_SYSTEM_EXTENSIONS" from autoreconf. 2003-09-17 Paul Eggert * gnulib-tool: Use "test -h", not "test -L", for portability to Solaris 8 /bin/sh. (This bug is fixed in Solaris 9.) (tags_regexp): Remove, since \| doesn't conform to POSIX. (sed_extract_prog): Issue s commands one-by-one, rather than using \| in one s command. 2003-09-16 Paul Eggert * lib/linebuffer.c (readlinebuffer): Return NULL immediately upon input error, instead of returning NULL the next time we are called (and therefore losing track of errno). 2003-09-16 Bruno Haible * gnulib-tool (func_create_testdir): Warn about duplicated dependencies. 2003-09-15 Paul Eggert * modules/argmatch, modules/fatal, modules/obstack, modules/xalloc, modules/xgethostname: Sort dependencies by importance, not alphabetically. 2003-09-15 Paul Eggert * lib/getndelim2.c (getndelim2): Don't trash errno when a read fails, so that the caller gets the proper errno. * lib/readutmp.c (read_utmp): Likewise. Check for fstat error. Close stream and free storage when failing. 2003-09-14 Karl Berry * config/srclist.txt (strdup.c): disable for c89 changes. 2003-09-14 Jim Meyering * lib/getloadavg.c: Correct cpp indentation. * lib/strdup.c: Likewise. * lib/vasnprintf.c: Likewise. 2003-09-14 Bruno Haible * modules/fwriteerror: New file. * MODULES.html.sh (func_all_modules): Add fwriteerror. 2003-09-14 Bruno Haible * lib/fwriteerror.h: New file. * lib/fwriteerror.c: New file. 2003-09-12 Paul Eggert * modules/argmatch, modules/exitfail, modules/fatal, modules/obstack, modules/xgethostname, modules/xalloc: Depend on exit. 2003-09-12 Paul Eggert * m4/error.m4: Require AC_FUNC_STRERROR_R rather than invoking it. * m4/extensions.m4 (gl_USE_SYSTEM_EXTENSIONS): Require AC_AIX and AC_MINIX, too, so that their extensions are available. * m4/prereq.m4 (jm_PREREQ_ADDEXT): Remove.

(jm_MACROS): Bump prerequisite from 2.52g to 2.57. Don't set GETGROUPS_LIB here; now it's done via getgroups.m4's wrapper function. AC_SUBST OPTIONAL_BIN_PROGS, OPTIONAL_BIN_ZCRIPTS, and MAN here, rather than just in sh-util/configure.in, so that the now-shared-by-fileutils-and-textutils lib/Makefile.am are all the same. Use AC_CONFIG_LIBOBJ_DIR(lib) to tell the new AC_FUNC_GETLOADAVG where to find getloadavg.c. Require AC_FUNC_FTW, gt_INTTYPES_PRI, gl_CLOCK_TIME, UTILS_SYS_OPEN_MAX, GL_FUNC_GETCWD_PATH_MAX, GL_FUNC_READDIR, gl_FSUSAGE, gl_MOUNTLIST, AC_FUNC_CANONICALIZE_FILE_NAME. Remove code that is now done by the newly-required macros. Append $(EXEEXT) to DF_PROG. AC_LIBOBJ fchdir-stub if fchdir doesn't exist; similarly for fchown. Do not invoke or require the following here, since prereq.m4 or some gnulib .m4 now does this for us: gl_REGEX, UTILS_FUNC_MKDIR_TRAILING_SLASH, jm_BISON, gl_FUNC_MKTIME, jm_FUNC_LSTAT, jm_FUNC_STAT, jm_FUNC_REALLOC, jm_FUNC_MALLOC, jm_FUNC_NANOSLEEP, jm_FUNC_READDIR, jm_FUNC_MEMCMP, jm_FUNC_GLIBC_UNLOCKED_IO, AC_FUNC_FNMATCH_GNU, jm_FUNC_PUTENV, jm_AC_PREREQ_XSTRTOUMAX, jm_AC_PREREQ_XSTRTOIMAX, AC_FUNC_ERROR_AT_LINE, jm_FUNC_GNU_STRFTIME, AC_FUNC_VPRINTF, vb_FUNC_RENAME, UTILS_FUNC_MKSTEP, jm_FUNC_UTIME, AM_FUNC_GETLINE, AC_FUNC_OBSTACK. Do not replace the following functions, as this is now the job of some gnulib .m4: strcasecmp, strncasecmp, dup2, gethostname, getusershell, sig2str, strcspn, stpcpy, strstr, strtol, strtoul strpbrk, euidaccess, memcmp, rmdir, rpmatch, strndup, strverscmp, atexit getpass, strdup, getpagesize. Replace 'raise'. Do not check for the following functions, as this is now the job of some gnulib .m4: bcopy, canonicalize_file_name, fchdir, ftime, getcwd, getmntinfo, resolvepath. But check for sysctl, setreuid, setregid. (jm_CHECK_ALL_HEADERS): Do not check for fenv.h. Check for sys/sysctl.h. (jm_CHECK_ALL_TYPES): Do not require AC_STRUCT_TM, AC_STRUCT_TIMEZONE, jm_CHECK_TYPE_STRUCT_TIMESPEC. Invoke gt_TYPE_SSIZE_T instead of checking for ssize_t ourselves. * m4/prereq.m4 (jm_PREREQ): Don't invoke macros; AC_REQUIRE them. Require every macro that gnulib/modules/* suggests for us. (jm_PREREQ_ADDEXT): New macro. (jm_PREREQ_STAT): Check for 'struct statfs' on Ultrix 4.4. Require jm_AC_TYPE_LONG_LONG instead of invoking it. * m4/physmem.m4 (gl_SYS__SYSTEM_CONFIGURATION): New macro. (gl_PHYSMEM): Use it. Also check for `table' function. Check for new headers and functions. Add check for sys/sysmp.h. With suggestions from Kaveh Ghazi. Ignore headers that are present but cannot be compiled. This avoids spurious warnings on Solaris 9 sparc with Forte Developer 7 C 5.4. 2003-08-15 Paul Eggert Document merge from coreutils. * modules/userspec: Depend on posixver. * modules/strftime: Depend on tzset. 2003-08-15 Paul Eggert * lib/config.charset, ref-add.sin, ref-del.sin: Use three spaces, rather than tab, after '#' in shell-script copyright notices. Suggested by Bruno Haible. 2003-08-15 Paul Eggert * config/srclist-update: Use three spaces, rather than tab, after '#' in shell-script copyright notices. Suggested by Bruno Haible. Remove unnecessary parenthesization in regular expression. 2003-08-15 Jim Meyering Merge from coreutils. * lib/xgethostname.c: Include . (xghostname): Don't exit for anything other than memory-related failure; just return NULL. * lib/userspec.c: Include "posixver.h". (parse_user_spec): Accept `.' as a separator only in pre-POSIX-200112 mode. * lib/strtoimax.c: Use #elif rather than #else #if. * lib/strftime.c (my_strftime) [!_LIBC && HAVE_TZNAME && HAVE_TZSET]: Remove function, now that we can rely on a working tzset function. [!_LIBC]: Ensure that the required autoconf test has been run. [!defined _NL_CURRENT && HAVE_STRFTIME]: Use underlying_strftime for %r. * lib/sha.c: Merge in some clean-up and optimization changes from glibc. * lib/sha.c (sha_stream) [BLOCKSIZE]: Move definition to top of file. Ensure that it is a multiple of 64. Rearrange loop exit tests so as to avoid performing an additional fread after encountering an error or EOF. * lib/realloc.c: Update copyright date. 2003-08-15 Jim Meyering and Paul Eggert Merge from coreutils. * lib/readutmp.h (HAVE_UTMPX_H): Undef if struct utmp has the ut_exit member but strut utmpx does not. Needed for AIX 4.3.3. (UT_EXIT_E_TERMINATION, UT_EXIT_E_EXIT): Define. 2003-08-15 Jim Meyering and Paul Eggert Merges from coreutils, etc. * m4/strftime.m4 (_jm_STRFTIME_PREREQS): Require gl_FUNC_TZSET_CLOBBER. * m4/readutmp.m4 (gl_READUTMP): Check for ut_exit.ut_exit, ut_exit.e_exit, ut_exit.ut_termination, and ut_exit.e_termination members. 2003-08-14 Paul Eggert Help the merge from coreutils. * m4/gettimeofday.m4 (gl_GETTIMEOFDAY_REPLACE_LOCALTIME): New macro. (AC_FUNC_GETTIMEOFDAY_CLOBBER): Use it. * m4/tzset.m4: Use it too. 2003-08-14 Paul Eggert * modules/tzset: New file. 2003-08-14 Jim Meyering Merges from coreutils. * modules/fnmatch: Use the `$(FNMATCH_H)' notation for AC_REPLACED variable names, rather than @FNMATCH_H@. * modules/alloca: Likewise for $(ALLOCA_H). * modules/fnmatch (fnmatch.h): Use `$@' in the commands, in place of the three copies of the literal target, `fnmatch.h'. * modules/alloca (alloca.h): Likewise. 2003-08-14 Jim Meyering Merge from coreutils. * m4/tzset.m4: New file. * m4/ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS): Move the MOUNTED_VMOUNT test to precede the MOUNTED_GETMNTENT1 tests, since otherwise, AIX 5.1 systems would end up using the latter. MOUNTED_GETMNTENT1 support is inadequate on such systems: 1) detecting whether a file system is remote doesn't work 2) the MOUNTED_VMOUNT code reports the HOSTNAME:/MOUNT_POINT, while the MOUNTED_GETMNTENT1 code reports merely /MOUNT_POINT. Reported by Mike Jetzer. 2003-08-14 Jim Meyering Merge from coreutils. * lib/obstack.h: Whitespace changes. * lib/mountlist.c: Remove anachronistic casts of xmalloc, xrealloc, and xcalloc return values. (read_filesystem_list) [MOUNTED_GETFSSTAT]: Use MNT_NOWAIT, rather than MNT_WAIT. Otherwise, `df DIR' could hang on OSF/1 5.1 for DIR on both local and remote file systems. Reported by (and fix confirmed by) Nelson H. F. Beebe. (read_filesystem_list) [MOUNTED_VMOUNT]: Detect any error from mntctl. Use mntctl's return value to drive the entry-processing loop, since we can't rely on the value of the vmt_length member in the last entry. On some systems doing so could result in exhausting virtual memory. Based in part on a patch from Mike Jetzer. 2003-08-14 Jim Meyering and Paul Eggert Merges from coreutils, plus other fixes. * lib/physmem.c: Merge in portability changes from gcc/libiberty to support AIX, IRIX, Tru64, and Windows. See the ChangeLog there for credits and details. Thanks to Kaveh Ghazi for helping to keep these files in sync. (ARRAY_SIZE): Define it. (physmem_total, physmem_available): Add comments. From Kaveh Ghazi. * lib/memcasecmp.c: Remove unnecessary parentheses after 'defined'. (memcasecmp): Don't assume size_t fits in unsigned int. Remove casts and duplicate code. * lib/md5.c: Include and unconditionally. (memcpy): Remove definition. Merge in some clean-up and optimization changes from glibc. [BLOCKSIZE]: Move definition to top of file. Ensure that it is a multiple of 64. Rearrange loop exit tests so as to avoid performing an additional fread after encountering an error or EOF. * lib/md5.h (md5_uintptr): Define. * lib/makepath.c (CLEANUP_CWD): Report an error if we failed to return to the initial working directory. Preserve errno for caller. * lib/idcache.c: Include "xalloc.h". (xmalloc, xrealloc): Remove decls. (getuser): Remove casts no longer required in C89. * lib/human.c: Include stdio.h, for sprintf. * lib/group-member.c: Include "xalloc.h". (xmalloc, xrealloc): Remove decls. (get_group_info): Remove casts no longer required in C89. * lib/getusershell.c (readname): Remove casts no longer required in C89. * lib/gettimeofday.c (rpl_gmtime, rpl_tzset): New functions. * lib/getline.c: Whitespace fix, from coreutils. 2003-08-13 Paul Eggert * m4/exclude.m4 (gl_EXCLUDE): Require AC_C_INLINE, AC_HEADER_STDC. Check for isascii. * m4/gettext.m4, iconv.m4, intdiv0.m4, inttypes-pri.m4, lib-link.m4, lib-prefix.m4, longdouble.m4, po.m4, progtest.m4, signed.m4: Undo previous (whitespace-only) change. 2003-08-13 Paul Eggert * lib/exclude.c: Include (IN_CTYPE_DOMAIN): New macro. (is_space): New fn. (add_exclude_file): If LINE_END is a space, ignore trailing spaces and empty lines. * lib/argp-help.c, argp-parse.c, config.charset, getopt.h: Undo previous (whitespace-only) change. 2003-08-13 Paul Eggert * config/srclist-update: Change update back to the old behavior, leaving whitespace alone. Use one 'sed' command rather than a pipeline. (fixlicense): Now a variable, not a function. (remove_trailing_blanks): Remove. (fixfile): Don't invoke unexpand or cat, or remove trailing blanks. * config/config.guess, config.sub, install-sh, missing, texinfo.tex: Undo previous (whitespace-only) change. 2003-08-12 Paul Eggert Merge from coreutils. * modules/euidaccess: Add lib_SOURCES, include for new file euidaccess.h 2003-08-12 Paul Eggert * m4/gettext.m4, iconv.m4, intdiv0.m4, inttypes-pri.m4, lib-link.m4, lib-prefix.m4, longdouble.m4, po.m4, progtest.m4, signed.m4: Normalize leading white space and remove trailing white space. Merge from coreutils * m4/euidaccess.m4 (gl_FUNC_EUIDACCESS): Check for euidaccess decl. * m4/lib-ld.m4, lib-link.m4, lib-prefix.m4: Regenerate from gettext 0.12.1. These files are now being upgraded automatically by ../config/srclist-update. 2003-08-12 Paul Eggert * lib/argp-help.c, argp-parse.c, config.charset, getopt.h: Normalize leading white space and remove trailing white space. * lib/ref-add.sin, ref-del.sin: Use '#' before empty line in copyright notice, as per ../config/srclist-update. Merge from coreutils. * lib/euidaccess.h: New file. * lib/euidaccess.c: Include it. * lib/.cppi-disable: Add printf-args.h, printf-parse.h, stdbool_.h, vasnprintf.h, vasprintf.h. Remove strdup.c, gettext.h. * lib/regex.h, strdup.c, strtoll.c, strtoul.c: Normalize white space. 2003-08-12 Paul Eggert * config/srclist-update: Add copyright notice. (remove_id_lines, remove_trailing_blanks): New constants. (fixfile): Use them to normalize spacing a bit in copied files. * config/config.guess, config.sub, install-sh, missing, texinfo.tex: Normalize leading white space and remove trailing white space. * config/texinfo.tex: Sync with texinfo. * config/srclist.txt: Don't get regex.h, strdup.c, strtoll.c, strtoul.c from libc, to merge coreutils whitespace changes. * config/srclist.txt: Get the following m4 files from gettext: codeset.m4, gettext.m4, glibc21.m4, iconv.m4, intdiv0.m4, inttypes-pri.m4, lcmessage.m4, lib-ld.m4, lib-link.m4, lib-prefix.m4, longdouble.m4, nls.m4, po.m4, progtest.m4, signed.m4, wchar_t.m4, wint_t.m4. 2003-08-12 Karl Berry * config/srclist.txt: can't sync vasnprintf.c any more, changes have been made. 2003-08-11 Paul Eggert * modules/gnu-source, m4/gnu-source.m4: Remove; we're assuming Autoconf 2.54 or later now. Suggested by Bruno Haible. * MODULES.html.sh (func_all_modules): Remove gnu-source. 2003-08-11 Bruno Haible * m4/vasnprintf.m4 (gl_PREREQ_VASNPRINTF): Also check for wcslen. 2003-08-11 Bruno Haible * lib/vasnprintf.c (local_wcslen): New function, for Solaris 2.5.1. (vasnprintf): Use it instead of wcslen. 2003-08-11 Bruno Haible * lib/stdbool_.h (_Bool): Undo last change; instead use a negative enum value to ensure that _Bool promotes to int. Use #define for _Bool when using the Solaris C compiler. Adds comments suggested by Paul Eggert. 2003-08-10 Karl Berry * lib/regex.h: update from libc (whitespace fix). 2003-08-09 Paul Eggert Merge some files from coreutils. These changes were originally made by Jim Meyering. * lib/acl.c: Include before ; many older Unixes require this. * lib/alloca.c (alloca): Remove cast to argument of free; no longer needed in C89. * lib/alloca_.h, regex.h: Fix white space to match what GNU indent does. 2003-08-09 Paul Eggert * m4/regex.m4 (jm_INCLUDED_REGEX): Change "\201" to "\371"; apparently Emacs's Unicode mode got confused before my 2003-08-05 checkin. 2003-08-08 Paul Eggert * m4/extensions.m4: New file. * m4/timespec.m4 (jm_CHECK_TYPE_STRUCT_TIMESPEC): Require gl_USE_SYSTEM_EXTENSIONS. * m4/unlocked-io.m4 (jm_FUNC_GLIBC_UNLOCKED_IO): Require gl_USE_SYSTEM_EXTENSIONS rather than AC_GNU_SOURCE. 2003-08-08 Paul Eggert * MODULES.html.sh (func_all_modules): Add extensions, gnu-source. * modules/extensions, modules/gnu-source: New files. * modules/timespec, modules/unlocked-io: Depend on extensions. 2003-08-07 Paul Eggert * modules/restrict: New file. * MODULES.html.sh (func_all_modules): Add restrict. * modules/regex: Depend on restrict. 2003-08-07 Paul Eggert * m4/restrict.m4: New file. * m4/regex.m4 (jm_PREREQ_REGEX): Add gl_C_RESTRICT. 2003-08-07 Bruno Haible * modules/getndelim2 (Makefile.am): Add the files to EXTRA_DIST, not lib_SOURCES, because getndelim2.m4 now uses AC_LIBOBJ(getndelim2). 2003-08-07 Bruno Haible * m4/getndelim2.m4 (gl_GETNDELIM2): Use AC_LIBOBJ(getndelim2). This makes the module 'getndelim2' compatible with the module 'getline'. 2003-08-05 Paul Eggert * m4/regex.m4 (jm_INCLUDED_REGEX): Replace a single non-ASCII byte with "\201" to avoid glitches when editing that source file with multi-gnome-terminal. 2003-08-05 Paul Eggert * lib/bumpalloc.h: Remove. 2003-08-05 Paul Eggert * MODULES.html.sh (func_all_modules): Remove bumpalloc. * modules/bumpalloc: Remove. 2003-08-04 Paul Eggert * lib/getloadavg.c: Change copyright notice and spacing to conform to GNU coding style.

From glibc. * lib/getdate.y (date): Also accept dates like May-23-2003; suggestion from Karl Berry, implemented by Jim Meyering. * lib/getgroups.c: Include "xalloc.h" instead of declaring xalloc fns; from Dmitry V. Levin. Remove anachronistic cast of xrealloc. * lib/fnmatch_.h (__const): Remove. Use 'const'. * lib/fnmatch_loop.c (NEW_PATTERN): Cast alloca return value to proper type. Otherwise, it wouldn't compile with at least /bin/cc on ymp-cray-unicos9.0.2.X. Combine two mostly-identical uses of alloca into one. Thanks to the Cray-Cyber project for access to a Cray Y-MP. 2003-08-04 Dave Love [From Emacs.] * lib/getloadavg.c: Check `__unix' as well as `unix'. Use #ifdef, not #if. Check HAVE_LIBKSTAT as well as LOAD_AVE_TYPE. Check F_SETFD, not FD_SETFD. Use HAVE_STRUCT_NLIST_N_UN_N_NAME, not obsolete NLIST_NAME_UNION. [__GNU__]: Undef BSD and FSCALE. [!NLIST_STRUCT]: Remove conditional definition of NLIST_STRUCT. 2003-08-03 Paul Eggert * lib/stdbool_.h (_Bool): Make it signed char, instead of an enum type, so that it's guaranteed to promote to int. See: 2003-08-03 Karl Berry * config/depcomp: update from automake. 2003-07-31 Paul Eggert * lib/strerror.c: Include config.h, limits.h. Declare sprintf.

Include "closeout.h" right after config.h, to test that it can stand by itself. Include "exitfail.h". Clients should set exit_failure instead. (EXIT_FAILURE): Remove; no longer needed. Do not include . 2003-07-18 Bruno Haible * modules/getndelim2: New file. * modules/getline: Share files with module getndelim2. * modules/getnline: Depend on getndelim2 instead of sharing files with it.

(getline, getdelim): Update. 2003-07-17 Bruno Haible * lib/Makefile.am: Remove file. * lib/Makefile.in: Remove file. 2003-07-17 Bruno Haible * configure.in: Remove file. * Makefile.in: Remove file. 2003-07-17 Bruno Haible * MODULES.html.sh: Put the right before . 2003-07-16 Karl Berry * config/srclist-update: was running fixlicense twice, which caused texinfo.tex to be nullified for some reason. Simplify, $gplsrc is no longer needed as far as I can see? 2003-07-16 Jim Meyering * modules/save-cwd: Depend on xgetcwd. From Derek Price. 2003-07-15 Paul Eggert * config/srclist.txt: Get the following files from gettext-runtime/intl instead: config.charset, localcharset.c, localcharset.h, ref-add.sin, ref-del.sin. From Bruno Haible. * config/srclist-update (fixfile): Change grep pattern again, since the previous fix didn't work (there was another trailing $). Use '[$]' to escape the $s. 2003-07-15 Karl Berry * lib/vasnprintf.c: update from gettext. 2003-07-15 Karl Berry * config/srclist-update (fixfile): Change grep pattern, since 'Id' gets expanded when surrounded by '$'. 2003-07-15 Jim Meyering * modules/save-cwd: Don't depend on error. From Derek Price. 2003-07-15 Jim Meyering * lib/makepath.c (make_path): Enclose diagnostic in _(...). 2003-07-14 Simon Josefsson * modules/mempcpy: New file. * MODULES.html.sh (func_all_modules): Add mempcpy. 2003-07-14 Simon Josefsson * m4/mempcpy.m4: New file. 2003-07-14 Simon Josefsson * lib/mempcpy.h: New file. * lib/mempcpy.c: New file. 2003-07-14 Paul Eggert * modules/getdate, modules/posixtm: Depend on mktime. 2003-07-14 Paul Eggert * lib/ceill.c, expl.c, floorl.c, frexpl.c, ldexpl.c, mathl.h, sincosl.c, sqrtl.c, trigl.c, trigl.h, poll.c, poll_.h, mkstemp.c, unicodeio.c, unicodeio.h, unlocked-io.h: Switch from LGPL to GPL. 2003-07-14 Paul Eggert * lib/asnprintf.c, asprintf.c, config.charset, gettext.h, localcharset.c, localcharset.h, mkdtemp.c, printf-args.c, printf-args.h, printf-parse.c, printf-parse.h, ref-add.sin, ref-del.sin, setenv.c, unsetenv.c, vasnprintf.c, vasnprintf.h, vasprintf.c, vasprintf.h: Regenerate. These files are now being updated automatically by ../config/srclist-update. This changes their license from LPGL to GPL. 2003-07-14 Paul Eggert * config/srclist.txt: Add tons more gettext files. $GETTEXT is now assumed to refer to the root of the most recent stable gettext version. * config/srclistvars.sh: Add defaults for eggert. * config/srclist-update: Convert LGPL to GPL in shell scripts, too. Match "This program" as well as "The program". This is needed for gettext. 2003-07-14 Jim Meyering Don't emit diagnostics. Let callers do that. * lib/save-cwd.c: Don't include "error.h". (save_cwd): Don't call error. Ensure that errno is valid when returning nonzero. * lib/save-cwd.h (restore_cwd): Update prototype. * lib/save-cwd.c (restore_cwd): Remove two parameters. Simplify. Don't call error upon failure. Let callers do that. (save_cwd): Mention that Irix 5.3 has the same problem as SunOS 4 when auditing is enabled. But don't bother updating the #if. 2003-07-11 Alexandre Duret-Lutz * lib/obstack.h (__INT_TO_PTR): Revert change of 2003-03-13; it breaks C++ compilation. [!__GNUC__ || !__STDC__] (obstack_finish): Cast result to void*. 2003-07-10 Simon Josefsson * modules/strchrnul (Makefile.am): Add strchrnul.h. 2003-07-10 Jim Meyering * m4/clock_time.m4: Remove trailing blank. * m4/intmax_t.m4: Likewise. 2003-07-10 Jim Meyering * lib/vasnprintf.c: Remove trailing blanks.

Add $LIBCSRC/sysdeps/generic/strtoul.c. In comments, add more libc files that differ from gnulib for one reason or another; we'd like this list to be smaller but for now let's document what we have. 2003-07-08 Paul Eggert * config/srclist-update: Port to POSIX 1003.1-2001 hosts by avoiding the use of GNU extensions. Change "x=`eval echo $x`" to the shorter and sweeter "eval x=$x". * config/srclist.txt: Get lib/argp* from glibc. 2003-07-07 Paul Eggert * lib/mktime.c: Fix some boundary cases and remove need for floating point. Issue a compile-time diagnostic if time_t is floating point, or if two's complement arithmetic is not in effect, or if arithmetic right shift does not propagate the sign. These assumptions were all in the original code but they weren't checked. (TIME_T_MIDPOINT, verify): New macros. (__isleap): Remove; it has integer overflow problems. (leapyear): New function, without those problems. (ydhms_tm_diff): Remove; splitting into two parts. (ydhms_diff): New function, containing the arithmetic part of the old ydhms_tm_diff function. Issue a compile-time diagnostic if we are not using C99 integer division. Avoid casts when possible. (guess_time_tm): New function, containing the checking part of the old ydhms_tm_diff function. Return the new value, rather than the difference between it and the old. Accept a new argument T so that *T specifies the old value. Check for overflow in the result. (__mktime_internal): Use a time_t offset, not a long int offset. This undoes the 2003-06-04 change, which is no longer needed now that we have better overflow checking. (localtime_offset): Likewise. (__mktime_internal): Avoid harmful overflow on hosts where time_t and long are 64-bit but int is only 32-bit. (ydhms_diff): Use long int to store year1 and yday1. Issue a compile-time diagnostic if long int is not wide enough. (__mktime_internal): Use long int to store adjusted year and yday. Use plain C rather than preprocessor commands, if that doesn't affect efficiency. Check for overflow (and try to repair) after each probe rather than checking only at the very end. This avoids some bugs (e.g., southern hemisphere, behind GMT, and GMT offset at minimum time does not equal GMT offset at maximum time). Use integer to check for overflow rather than floating point; this is more portable to non-IEEE hosts, and is a tad faster. When we detect that we are oscillating between two values, don't check whether tm_isdst has the requested value, since we already know the answer. When tm_isdst has the wrong value, use a different heuristic to find the right one, based on the extreme values actually observed in practice in tz2003a, rather than the (overly optimistic) "previous 3 calendar quarters". (not_equal_tm, print_tm, check_result): Use "const T" rather than "T const" to accommodate glibc style. (check_result): Use less-confusing report format. "long" -> "long int. (main): Likewise. Don't loop if the iteration overflows time_t. Allow a negative step in the iteration. 2003-07-06 Karl Berry * config/depcomp: update from automake. * config/config.sub: update from prep. 2003-07-03 Karl Berry * config/config.guess: update from prep. 2003-07-01 Paul Eggert * m4/xreadlink.m4 (gl_XREADLINK): Don't check for sys/types.h, since xreadlink.c now includes it unconditionally. 2003-07-01 Paul Eggert * lib/xreadlink.c: Include unconditionally, instead of having it depend on HAVE_SYS_TYPES_H. 2003-07-01 Bruno Haible * m4/ssize_t.m4 (gt_TYPE_SSIZE_T): Don't include . should be sufficient.

This fixes a bug when processing fall-backwards gaps immediately after a long period of daylight-saving time. * lib/mktime.c: Assume freestanding C89 or better. (HAVE_LIMITS_H): Remove. Assume it's 1. (__P): Remove; not used. (CHAR_BIT, INT_MIN, INT_MAX): Remove; defines them. (mktime, not_equal_tm, print_tm, check_result, main): Use prototypes. Use const * where appropriate. (main): Fix typo in testing code that uncovered by above changes.

(localtime_offset): Now long int, not time_t, because we want it to be guaranteed to be signed. All uses changed. (__mktime_internal): If overflow would occur when adding offset, don't add it. Merge 'human' changes from coreutils. Rewrite to support locale-specific notations like thousands separators. * lib/human.c: Simplify authorship notice. Include human.h immediately after config.h. , : Do not include; no longer needed. : Do not include, since human.h does.

(power_letter): Renamed from suffixes. (generate_suffix_backwards): Remove. (adjust_value): Now takes int style (because of human.h changes) and long double value (for greater precision on some platforms). (group_number): New function. (human_readable): Use it. Use integer options, not enum. Put the options before the sizes in the arg list. Support all the new options. The old human_readable function has been removed; use inttostr.h instead. (human_readable, default_block_size, humblock): Use uintmax_t, not int, for block sizes. (human_readable_inexact, block_size_types): Remove. (block_size_opts): New constant.

(human_readable): Size args are now uintmax_t, not int. (human_options): New decl. * lib/exclude.c: (new_exclude, add_exclude): Remove casts that are unnecessary now that we assume C89 or better. This change imported from coreutils. * lib/mktime.c (__mktime_internal): Do not reject negative timestamps arbitrarily. This is the same patch as 2003-05-28, but it got lost in the 2003-05-30 sync from glibc. .h files should stand alone, but we shouldn't include if we can get away with just . * lib/__fpending.h, addext.c, backupfile.c, exclude.c, getline.c, malloc.c, putenv.c, realloc.c, strcasecmp.c: Include rather than , as we merely need size_t. * lib/dirname.h, memcoll.h, xalloc.h, xmemcoll.h: Include , to get size_t. * lib/hash.h, linebuffer.h, readtokens.h, stdio-safer.h, version-etc.h: Include , to get FILE. * lib/memcasecmp.c: Don't include , as we can assume memcasecmp.h has included and all we need is size_t. * lib/memcoll.c: Include "memcoll.h", which gets us size_t and checks our interface, instead of including 2003-06-04 Paul Eggert * config/srclist.txt ($LIBCSRC/time/mktime.c lib gpl): Comment out for now, as glibc mktime is buggy on non-glibc systems. 2003-06-03 Karl Berry * config/config.sub: update from prep. 2003-06-02 Paul Eggert [from coreutils] Fix some minor time-related bugs with POSIX time arguments. Some valid time stamps were being rejected (notably -1, and time stamps before 1900 on 64-bit hosts). And some invalid time stamps were being accepted, e.g. September 31. * lib/posixtm.h (posixtime): Return bool instead of time_t, so that we can return (time_t) -1 successfully. * lib/posixtm.c: Likewise. [HAVE_STDBOOL_H]: Include . (bool, false, true) [!HAVE_STDBOOL_H]: New type. (t): Remove static var. (year, posix_time_parse): Now takes struct tm * arg to modify, instead of static var. All uses changed. (year): Do not reject years before 1900; they can occur with 64-bit time_t. (posix_time_parse): Do not check for out-of-range components; that is now the caller's responsibility, since our checks were only approximations. (posixtime): Use mktime to check for out-of-range components, since it knows them exactly. If mktime returns (time_t) -1, check whether an error actually occurred by invoking localtime on -1. (main) [TEST_POSIXTIME]: Check for input data errors, and report posixtime failures better. Improve the test data (in comments only). 2003-06-02 Karl Berry * config/mkinstalldirs (version): new variable. (--version): new option. (usage): improve message. 2003-05-30 Karl Berry * lib/mktime.c: update from libc. 2003-05-30 Bruno Haible * modules/gettext: Add files m4/nls.m4 and m4/po.m4. * config/config.rpath: Upgrade to gettext-0.12.1. 2003-05-30 Bruno Haible * m4/gettext.m4: Upgrade to gettext-0.12.1. * m4/nls.m4: New file, from gettext-0.12.1. * m4/po.m4: New file, from gettext-0.12.1. * m4/progtest.m4: Upgrade to gettext-0.12.1. 2003-05-30 Bruno Haible * lib/config.charset: Upgrade to gettext-0.12.1 and libiconv-1.9.1. * lib/localcharset.h: Likewise. * lib/localcharset.c: Likewise. 2003-05-29 Karl Berry * config/config.rpath: update from gettext. 2003-05-28 Paul Eggert Assume the headers required for C89 freestanding compilers. * m4/backupfile.m4 (gl_BACKUPFILE): Don't check for limits.h. * m4/fsusage.m4 (gl_PREREQ_FSUSAGE_EXTRA): Likewise. * m4/human.m4 (gl_HUMAN): Likewise. * m4/pathmax.m4 (gl_PATHMAX): Likewise. * m4/rpmatch.m4 (gl_FUNC_RPMATCH): Likewise. * m4/userspec.m4 (gl_USERSPEC): Likewise. * m4/xreadlink.m4 (gl_XREADLINK): Likewise. * m4/xstrtol.m4 (gl_PREREQ_XSTRTOL): Likewise. * m4/quote.m4 (gl_QUOTE): Don't check for stddef.h. 2003-05-28 Paul Eggert Assume the headers required for C89 freestanding compilers. * lib/addext.c, lib/backupfile.c, lib/fsusage.c, lib/human.c, lib/pathmax.h, lib/rpmatch.c, lib/userspec.c, lib/xreadlink.c, lib/xstrtol.c: Include without checking for HAVE_LIMITS_H. * lib/backupfile.c, lib/fsusage.c, lib/hash.c, lib/human.c, lib/safe-read.c, lib/userspec.c, lib/xstrtol.c (CHAR_BIT): Don't define, since is guaranteed to do that. * lib/fatal.c: Include without checking for __STDC__. * lib/exclude.c: Include unconditionally. * lib/tempname.c: Include unconditionally. * lib/hash.c: Include , since we no longer define CHAR_BIT. * lib/modechange.c, rpmatch.c (NULL): Don't define, since does that. * lib/quote.c: Dont include or ; not needed. * lib/safe-read.c (INT_MAX): Don't define, since does that. * lib/safe-read.c (TYPE_MINIMUM, TYPE_MAXIMUM): Remove; no longer needed. * lib/xstrtol.c: Likewise. * lib/safe-read.c: Remove TYPE_SIGNED; no longer needed. * lib/savedir.c: Include instead of defining NULL. * lib/addext.c (addext): Use assignment rather than cast, to avoid warnings on some platforms. * lib/mktime.c (__mktime_internal): Do not reject negative timestamps arbitrarily. 2003-05-26 Jim Meyering Merge in a change from coreutils: * m4/dirfd.m4 (UTILS_FUNC_DIRFD): Test the cache variable, not one that is guaranteed to be `no'. Use `no_such_member' to indicate that condition, rather than `-1' which is slightly misleading. Change the name of the cache variable to have the gl_ prefix. Prompted by a patch from Richard Dawe for DJGPP. 2003-05-24 Karl Berry * config/config.guess: update from prep. 2003-05-22 Karl Berry * gnulib-tool (func_usage): =LIBRARY not =libRARY in help msg. 2003-05-20 Karl Berry * config/config.guess: update from prep. 2003-05-18 Karl Berry * config/srclistvars.sh (TEXMF): use TEXMFROOT instead, since TEXMF might actually be set by the user. * config/depcomp, install-sh, mdate-sh: update from automake. 2003-05-17 Bruno Haible * m4/dirfd.m4 (UTILS_FUNC_DIRFD): Fix a quoting bug leading to an invalid expansion for AC_EGREP_CPP. * m4/strtoimax.m4 (gl_FUNC_STRTOIMAX): Likewise. * m4/strtoumax.m4 (gl_FUNC_STRTOUMAX): Likewise.

(EXCLUDE_macros_do_not_collide_with_FNM_macros): Use FNM_PATHNAME instead of FNM_FILE_NAME, for compatibility with pure POSIX sytems. 2002-12-06 Paul Eggert Undo the 2001-07-02 change for jm-glibc-io, as it was too much of a pain in practice to deal with generated m4 files. This change goes together with the 2002-12-04 unlocked-io.h change in ../lib. * m4/Makefile.am.in (Makefile.am): Don't mention jm-glibc-io.m4n and jm-glibc-io.m4, as they are no longer a special case. * m4/jm-glibc-io.m4: Rename from jm-glibc-io.m4n, and remove the kludge and the auto-generation stuff. Check only whether the functions are declared, not whether they exist, since older hosts that don't declare the functions can't use the optimization anyway. 2002-12-06 Jim Meyering * lib/error.c: Be consistent: change `#ifndef _LIBC' to `#if !_LIBC'. Merge in changes from libc's misc/error.c, in preparation for the merge of gnulib's changes back into libc. * lib/error.c (_): Define only if not already defined.

Check for arithmetic overflow when computing combined size. 2002-12-04 Paul Eggert Do not generate unlocked-io.h automatically, since it's easier to maintain it by hand. * lib/unlocked-io.h: New file, from GNU diffutils, but with proper copyright notice and attribution. * lib/gen-uio: Remove. * lib/Makefile.am: Add copyright notice. (libfetish_a_SOURCES): Add unlocked-io.h. (BUILT_SOURCES, all-local): Remove unlocked-io.h. (DISTCLEANFILES, io_functions): Remove macros. (EXTRA_DIST): Remove gen_uio.

(INT_MAX): Provide fallback. (safe_read): Rewrite to iterate IFF the read fails with EINTR. * lib/safe-read.h (SAFE_READ_ERROR): Define. 2002-12-02 Bruno Haible * lib/safe-write.c (CHAR_BIT, TYPE_SIGNED, TYPE_MINIMUM, TYPE_MAXIMUM): Define, taken from safe-read.c. (INT_MAX): Provide fallback. (safe_write): Rewrite to iterate IFF the write fails with EINTR. * lib/safe-write.h (SAFE_WRITE_ERROR): Define. * lib/safe-read.c (EINTR): Remove definition.

Include , for size_t, so that we can be included first. (PARAMS): Remove; we now assume C89 or later. All uses removed. * lib/quotearg.c: Include quotearg.h immediately after config.h. No need to include stddef.h or sys/types.h any more. Surround local include files with "", not "<>". Assume HAVE_LIMITS_H unconditionally, as we assume C89.

(quotearg_buffer_restyled, quotearg_n, quotearg_n_style, quotearg_char): Use SIZE_MAX rather than (size_t) -1 when we are talking about "infinity". (quotearg_buffer_restyled): Fix bug when quoting trigraphs. 2002-11-22 Paul Eggert * lib/hash.c: Avoid use of , as the GNU Coding Standards hint that one should use `if (! x) abort ();' rather than `assert (x);', and anyway it's one less thing to worry about configuring. (hash_lookup, hash_get_first, hash_get_next, hash_find_entry, hash_rehash, hash_insert): Use abort rather than assert. 2002-11-22 Bruno Haible * lib/safe-read.h: Assume C89. Add comments.

Include stdlib.h, for EXIT_FAILURE. Always include , since we assume C89. (EXIT_FAILURE): Remove pre-C89 bug workaround. * lib/argmatch.h: Do not include or . Include instead, since it's all we need for size_t. (PARAMS): Remove. All uses removed. (ARRAY_CARDINALITY): Do not bother to #undef.

From diffutils-2.8.2. * lib/fnmatch.h: Remove file. 2002-06-21 Jim Meyering * m4/c-bs-a.m4: Add comment, from diffutils-2.8.2. * m4/mbrtowc.m4: Likewise. * m4/mbstate_t.m4: Update from diffutils-2.8.2. * m4/mbswidth.m4: Reflect name change: s/AC_MBSTATE_T/AC_TYPE_MBSTATE_T. * m4/prereq.m4 (jm_PREREQ_QUOTEARG): Likewise. * m4/lib-link.m4: Update from gettext-0.11.2. * m4/gettext.m4: Likewise. * m4/jm-macros.m4 (jm_CHECK_ALL_HEADERS): Check for hurd.h. From Alfred M. Szmidt. 2002-06-18 Paul Eggert * lib/file-type.h: Report an error if neither S_ISREG nor S_IFREG is defined, instead of using a test specific to glibc 2.2. This should be safe, since POSIX requires S_ISREG and Unix Version 7 had S_IFREG. We don't need to check for since we don't use any symbols that it defines. 2002-06-15 Richard Dawe * lib/Makefile.am (lstat.c, stat.c, .sin.sed): Use t-$@, rather than $@-t, so that each temporary file name is unique and valid in the first 8 characters, for operation under DOS. 2002-06-15 Paul Eggert * m4/jm-macros.m4 (jm_CHECK_ALL_TYPES): Check for st_author. 2002-06-15 Jim Meyering Work even with DJGPP 2.03, which lacks support for symlinks. From Richard Dawe. * lib/xstat.in (S_ISLNK): Define to 0 if neither S_ISLNK nor S_IFLNK is defined. * lib/lchown.c (S_ISLNK): Likewise. 2002-06-15 Jim Meyering * lib/file-type.h (FILE_TYPE_H): Guard entire contents with #ifndef. For GNU libc 2.2 and newer, ensure that and have been included before this file. 2002-06-14 Jim Meyering * lib/file-type.h: Use the version from diffutils-2.8.2. * lib/file-type.c: Likewise. 2002-06-07 Jim Meyering * m4/prereq.m4 (jm_PREREQ_STAT): Check for sys/param.h and sys/mount.h. They're needed at least for NetBSD 1.5.2. ($statxfs_includes): Include those same headers. ($statxfs_includes): Include sys/vfs.h if available. ($statxfs_includes): Likewise for sys/statvfs.h. Check for the following members in both structs statfs and statvfs: f_basetype, f_type, f_fsid.__val, f_namemax, f_namelen. 2002-06-01 Jim Meyering * m4/d-type.m4 (jm_CHECK_TYPE_STRUCT_DIRENT_D_TYPE): Rename macro: s/D_TYPE_IN_DIRENT/HAVE_STRUCT_DIRENT_D_TYPE/. 2002-05-28 Jim Meyering * m4/readdir.m4 (jm_FUNC_READDIR): Undefine `mkdir', not `rmdir'. Reported by Volker Borchert. 2002-05-27 Jim Meyering Fix a problem seen only on nonconforming systems whereby ls.c's use of localtime, and then of gettimeofday would cause trouble: the localtime call used to initialize rpl_gettimeofday's save mechanism would clobber ls's current local time information so that in any long listing the first file would always be listed with date 1970-01-01. Analysis by Volker Borchert. * lib/gettimeofday.c (localtime): Undefine. (rpl_localtime): New function. 2002-05-27 Jim Meyering * m4/gettimeofday.m4 (AC_FUNC_GETTIMEOFDAY_CLOBBER): Also replace localtime. * m4/readdir.m4 (jm_FUNC_READDIR): Undefine `rmdir' so we don't try to use the replacement function; it wouldn't resolve at link time. Reported by Volker Borchert. 2002-05-22 Jim Meyering * lib/Makefile.am (libfetish_a_SOURCES): Add file-type.c and file-type.h. * lib/file-type.h: New file. * lib/file-type.c (file_type): New file/function. Extracted from diffutils. 2002-04-30 Jim Meyering * m4/prereq.m4 (jm_PREREQ): Add jm_PREREQ_STAT. 2002-04-29 Paul Eggert * m4/prereq.m4 (jm_PREREQ_SIG2STR): Remove; all callers changed. 2002-04-29 Paul Eggert * m4/prereq.m4 (jm_PREREQ_HARD_LOCALE): Check for stdlib.h. Do not check for alloca.h (no longer used) or stdbool.h (was never used?). Add AM_C_PROTOTYPES since hard-locale.h uses it. 2002-04-29 Paul Eggert * lib/hard-locale.c: Upgrade to version used in GNU Diffutils 2.8.1. 2002-04-29 Jim Meyering * m4/jm-macros.m4 (jm_MACROS): Remove use of AC_FUNC_STRNLEN. * m4/prereq.m4: Add jm_PREREQ_STRNLEN. Use AC_FUNC_STRNLEN here instead. * m4/jm-macros.m4: Don't AC_REQUIRE([AC_PROG_CC_STDC]). With autoconf-2.53a, it's part of AC_PROG_CC. 2002-04-28 Paul Eggert * m4/jm-macros.m4 (jm_MACROS): Add AC_REPLACE_FUNCS(sig2str). * m4/prereq.m4 (jm_PREREQ): Add jm_PREREQ_SIG2STR. 2002-04-28 Paul Eggert * lib/sig2str.h, lib/sig2str.c: New files. * lib/Makefile.am (libfetish_a_SOURCES): Add sig2str.h. 2002-04-28 Paul Eggert * lib/sig2str.h (SIGNUM_BOUND): Do not use WTERMSIG, to avoid depending on and WTERMSIG. Default to 64 instead of 127, since 64 is the largest conceivable number for ancient nonstandard hosts. * lib/sig2str.c: Do not include ; no longer needed. 2002-04-28 Jim Meyering * lib/sig2str.c (WTERMSIG): Remove definition (unused). 2002-04-24 Jim Meyering * m4/prereq.m4 (jm_PREREQ_HARD_LOCALE): New macro. (jm_PREREQ): Use it. * m4/getloadavg.m4: Check for these headers: locale.h unistd.h mach/mach.h fcntl.h. Check for this function: setlocale. 2002-04-24 Jim Meyering * lib/gettext.h: New file, from Gettext. * lib/Makefile.am (INCLUDES): Remove -I../intl. (libfetish_a_SOURCES): Add gettext.h. 2002-04-16 Jim Meyering * m4/prereq.m4 (jm_PREREQ_READUTMP): Also check for these members: ut_pid, ut_id, ut_exit. 2002-04-16 Jim Meyering * lib/readutmp.h (UT_TYPE): Remove definition (now in who.c). (HAVE_STRUCT_XTMP_UT_EXIT, HAVE_STRUCT_XTMP_UT_ID): Define. (HAVE_STRUCT_XTMP_UT_PID, HAVE_STRUCT_XTMP_UT_TYPE): Define. 2002-04-12 Jim Meyering * m4/ls-mntd-fs.m4 (checking for getmntinfo function...): Remove now-bogus check for f_type in sys/mount.h. Instead, just test for the existence of the getmntinfo function. Needed for Darwin 5.3. * m4/dirfd.m4 (UTILS_FUNC_DIRFD): Also detect when dirfd is a macro. This is necessary at least on Darwin 5.3. * m4/jm-macros.m4: Don't AC_REPLACE(strnlen), now that we use AC_FUNC_STRNLEN. Otherwise, we'd end up putting two copies of strnlen.o in the library, and that makes some versions of ranlib object. 2002-04-12 Jim Meyering * lib/dirfd.h (dirfd): Elide prototype if dirfd is a macro. 2002-04-09 Jim Meyering * m4/malloc.m4: (jm_FUNC_MALLOC): Change the `checking ...' message to be more precise. Rather than saying we're checking whether the function `works', say what we're testing. * m4/realloc.m4 (jm_FUNC_REALLOC): Likewise. Reported by Bruno Haible. 2002-03-10 Jim Meyering * lib/makepath.c (make_path): Remove a comma from a diagnostic. Suggestion from Santiago Vila. 2002-03-08 Jim Meyering * lib/rename.c: Mention that this wrapper is needed also on mips-dec-ultrix4.4 systems. 2002-03-02 Jim Meyering * lib/gettime.c (gettime): Test HAVE_CLOCK_GETTIME, not HAVE_CLOCK_SETTIME. 2002-02-27 Paul Eggert * m4/jm-macros.m4 (jm_MACROS): Do not replace stime; no longer used. Check for clock_settime. 2002-02-27 Paul Eggert * lib/nanosleep.h: Rename to.... * lib/timespec.h: New name for nanosleep.h.

Remove nanosleep.h. 2002-02-25 Paul Eggert * m4/acl.m4: New file. * m4/jm-macros.m4 (jm_MACROS): Require AC_FUNC_ACL. Do not check for acl or sys/acl.h, as AC_FUNC_ACL does that now. 2002-02-25 Paul Eggert * lib/acl.c, lib/acl.h: New files. * lib/Makefile.am (libfetish_a_SOURCES): Add acl.h, acl.c. 2002-02-24 Jim Meyering * lib/strnlen.c (strnlen): Define-away/undef so that an inconsistent prototype in string.h (on at least AIX4.3.2.0 w/gcc-2.95.3) doesn't cause trouble. Reported by Nelson Beebe. 2002-02-23 Paul Eggert * lib/path-concat.c (xpath_concat): Reorder code to pacify compilers that don't know that xalloc_die never returns. 2002-02-20 Jim Meyering * lib/getdate.c: Regenerate using bison-1.33. 2002-02-17 Jim Meyering * config/config.guess (main): Don't use `head -1'; it's no longer portable. Use `sed 1q' instead. 2002-02-16 gettextize * m4/codeset.m4: Upgrade to gettext-0.11. * m4/gettext.m4: Upgrade to gettext-0.11. * m4/glibc21.m4: Upgrade to gettext-0.11. * m4/iconv.m4: Upgrade to gettext-0.11. * m4/isc-posix.m4: Upgrade to gettext-0.11. * m4/lcmessage.m4: Upgrade to gettext-0.11. * m4/lib-ld.m4: New file, from gettext-0.11. * m4/lib-link.m4: New file, from gettext-0.11. * m4/lib-prefix.m4: New file, from gettext-0.11. * m4/progtest.m4: Upgrade to gettext-0.11. 2002-02-15 Paul Eggert * m4/prereq.m4 (jm_PREREQ_POSIXVER): New macro.

Otherwise, some versions of automake would omit the rule that makes Makefile from Makefile.in. 2002-01-21 Paul Eggert * lib/xmemcoll.h, lib/xmemcoll.c: New files. * lib/Makefile.am (libfetish_a_SOURCES): Add them. * lib/memcoll.c: Include errno.h, and declare errno if not defined. (memcoll): Set errno to zero if there is no error. * lib/quotearg.c (quotearg_buffer_restyled): Fix bug with quoting buffers containing NUL when backslashing escapes.

Bison (as of version 1.31) no longer papers over that mistake. 2002-01-05 Jim Meyering * lib/version-etc.c (version_etc_copyright): Update copyright year. 2001-12-19 Paul Eggert * lib/closeout.c (close_stdout_status): If ferror (stdout), do not silently exit merely because the output buffer happens to have nothing pending. 2001-12-18 Paul Eggert See the big note in ../ChangeLog. * lib/human.c (suffixes): Prefer K to k for 1024. (generate_suffix_backwards): New function. (human_readable_inexact): Use it. * lib/xstrtol.c (__xstrtol): If there is no number but there is a valid suffix, assume 1. "MB" now means decimal, "MiB" binary.

Don't cast xrealloc return value to char* Return NULL, not 0. 2001-12-09 Jim Meyering * lib/modechange.c (mode_compile): Add cast to avoid pedantic warning about `signed and unsigned type in conditional expression'. * lib/posixtm.c (posix_time_parse): Likewise. * lib/xreadlink.c (xreadlink): Add cast to avoid a pedantic warning. * lib/readtokens.c (readtoken): Declare an index to be of type unsigned to avoid a pedantic warning. * lib/getstr.c: Don't include assert.h. (getstr): Remove warning-evoking assertions. Return -1 if offset parameter is out of bounds. Change the type of a local from int to size_t. * lib/strftime.c (my_strftime_localtime_r): Include this function definition in the `#if ! HAVE_TM_GMTOFF' block. * lib/xgethostname.c: Remove declarations of xmalloc and xrealloc. Include xalloc.h instead. 2001-12-02 Jim Meyering * lib/tempname.c: Don't declare getenv, thus reverting the change of 2001-11-18. It's no longer necessary, now that stdlib.h is always included. * lib/regex.c [!__BOUNDED_POINTERS__]: Define away __bounded, __unbounded, and __ptrvalue. Reported by Uwe H. Steinfeld. 2001-11-30 Akim Demaille * lib/xstrdup.c: Include xalloc.h, so that xstrdup is declared before being defined. 2001-11-27 Paul Eggert * lib/quotearg.h (quotearg_n, quotearg_n_style): First arg is int, not unsigned. * lib/quotearg.c (quotearg_n, quotearg_n_style): Likewise. (SIZE_MAX, UINT_MAX): New macros. (quotearg_n_options): Abort if N is negative. Avoid overflow check on hosts where size_t is 64 bits and int is 32 bits, as overflow is impossible there. Fix off-by-one typo that caused unnecessary reallocation. 2001-11-27 Jim Meyering * lib/tempname.c: Merge with version from libc. * lib/regex.c: Likewise. * lib/tempname.c: Include stdlib.h unconditionally. On some old systems for which STDC_HEADERS is 0, it was not included, resulting in a warning about an integer-to-pointer conversion problem with getenv. Reported by Volker Borchert. 2001-11-26 Jim Meyering * lib/gtod.h: Remove file. * lib/Makefile.am (libfetish_a_SOURCES): Remove gtod.h. * lib/gettimeofday.c: Don't include gtod.h.

Merely declare it. * lib/hash.c (struct hash_table): Define it here instead. 2001-11-22 Jim Meyering * lib/hash.h: Bracket contents of file with #ifndef HASH_H_ ... #endif. 2001-11-20 Jim Meyering * m4/mkstemp.m4 (UTILS_FUNC_MKSTEMP): Update comment to reflect that SunOS 4.1.4 and Solaris 2.5.1 lose, too. 2001-11-19 Jim Meyering * m4/mkstemp.m4 (UTILS_FUNC_MKSTEMP): Don't bother with a temporary directory. Use "conftestXXXXXX" as the template. Suggestion from Paul Eggert. * m4/mkstemp.m4 (UTILS_FUNC_MKSTEMP): Close each descriptor immediately, so the test doesn't mistakenly hit the max-open-files limit. 2001-11-18 Paul Eggert * lib/tempname.c (TMP_MAX): Remove; no longer needed. (TEMPORARIES): New macro. (__gen_tempname): Use TEMPORARIES rather than TMP_MAX.

Prompted by a report from Bob Proulx. * m4/jm-macros.m4 (jm_MACROS): Don't test for mkstemp here. Instead, require UTILS_FUNC_MKSTEMP. 2001-11-17 Jim Meyering * m4/jm-macros.m4 (jm_MACROS): Remove code to set POW_LIBM. Now, that's done as part of AC_FUNC_STRTOD. 2001-11-17 Jim Meyering * lib/modechange.c (mode_adjust): Fix error introduced on 1999-04-26 that made e.g., `chmod a=,o=w,g=o F' cause F to be group readable rather than group writable. Patch by Juan F. Codagnone. * lib/readtokens.c: Remove explicit declarations of xmalloc and xrealloc, Instead, include "xalloc.h". * lib/mountlist.c: Include unlocked-io.h after all system headers. Remove explicit declarations of xmalloc, xrealloc, and xstrdup.

(physmem_total) [HAVE_PSTAT_GETSTATIC]: If sysconf couldn't be used to determine the amount of total physical memory, use pstat_getstatic. HPUX-11 doesn't define _SC_PHYS_PAGES. (physmem_available) [HAVE_PSTAT_GETSTATIC && HAVE_PSTAT_GETDYNAMIC]: If sysconf couldn't be used to determine the amount of available physical memory, use both pstat_getstatic and pstat_getdynamic. Based on a patch from Bob Proulx. 2001-11-10 Jim Meyering * m4/prereq.m4 (jm_PREREQ_PHYSMEM): New function. (jm_PREREQ): Use it. 2001-11-09 Jim Meyering * m4/jm-macros.m4: Require autoconf-2.52f. (AC_FUNC_ERROR_AT_LINE, AC_FUNC_OBSTACK, AC_FUNC_STRTOD): Use these AC_-prefixed names, not the AM_-prefixed ones. * m4/afs.m4 (jm_AFS): Quote the body. Patch by Akim Demaille. 2001-11-05 Jim Meyering * lib/xstat.in (slash_aware_lstat): Correct a misleading comment. 2001-11-04 Jim Meyering * m4/fpending.m4: Remove unused cruft that saved, set, and restored $DEFS. 2001-11-03 Jim Meyering * m4/jm-glibc-io.m4n (jm_FUNC_GLIBC_UNLOCKED_IO): Quote first arg of AC_DEFUN. * m4/dirfd.m4 (UTILS_FUNC_DIRFD): Rework so dirfd.c doesn't have to know the name of the variable in the macro definition. 2001-11-03 Jim Meyering * lib/argmatch.h (ARGMATCH_TO_ARGUMENT): Remove casts of first two args in argmatch_to_argument call. * lib/dirfd.c (dirfd): Reflect the fact that DIR_TO_FD now takes an argument. * lib/hash.c (hash_clear): Fix a bug that could lead to an infloop or e.g., a fault due to an attempt to free a NULL pointer. 2001-11-01 Jim Meyering * m4/dirfd.m4 (UTILS_FUNC_DIRFD): New macro. * m4/jm-macros.m4 (jm_MACROS): Require UTILS_FUNC_DIRFD. 2001-11-01 Jim Meyering * lib/dirfd.c, lib/dirfd.h: New files. * lib/Makefile.am (libfetish_a_SOURCES): Add dirfd.h. * lib/hash.c (hash_print) [TESTING]: Clean up. 2001-10-22 Paul Eggert * lib/hard-locale.c (alloca): Define to __builtin_alloca if __GNUC__, to avoid a warning if -Wall. 2001-10-22 Jeff Bailey * README: New file * doc/*: Add COPYING, COPYING.LIB, COPYING.DOC, fdl.texi (per RMS's instructions, this is now the canonical source) * lgpl/, gpl/: New directories. 2001-10-21 Paul Eggert * lib/regex.c (uintptr_t): Remove macro and decl; it's config.h's job. 2001-10-21 Jim Meyering * lib/obstack.c (_): Honor the setting of ENABLE_NLS. Otherwise, this code would end up calling gettext even in packages built with --disable-nls. * lib/getopt.c (_): Likewise. * lib/regex.c (_): Likewise. 2001-10-20 Paul Eggert * m4/error.m4 (jm_PREREQ_ERROR): Do not invoke AC_CHECK_FUNCS with strerror_r, as AC_FUNC_STRERROR_R does that. Check for strerror declaration. * m4/strerror_r.m4: Add copyright notice, as nontrivial m4 files are supposed to have them these days. (AC_FUNC_STRERROR_R): Always do char* test, so that it gets cached. Merge changes from latest Autoconf CVS. Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p, and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since POSIX decided to standardize on the int flavor of strerror_r. 2001-10-20 Paul Eggert * lib/error.c (strerror_r): Do not declare unless !_LIBC. Do not check for HAVE_DECL_STRERROR_R missing unless STRERROR_R_CHAR_P. Use strerror_r that is only a macro, even if it is not a function. (strerror): Check for HAVE_DECL_STRERROR before declaring. (private_strerror): Use prototypes, not old-style function definition. (print_errno_message): New function. Support the POSIX 'int'-flavored strerror_r, as well as the traditional char*-flavored one. (error_tail, error, error_at_line): Use it. 2001-10-11 Jim Meyering * lib/argmatch.c (argmatch_invalid): Use quotearg_n_style (0, ... and quote_n (1, ... to avoid clobbering a buffer. 2001-10-05 Jim Meyering * lib/Makefile.am: (libfetish_a_SOURCES): Add hash-pjw.c and hash-pjw.h. * lib/hash-pjw.c: New file (factored out of fileutils' remove.c). * lib/hash-pjw.h: New file. 2001-09-30 Jim Meyering * m4/ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS): See if `struct fsstat' has the `f_fstypename' member. Use that to define FS_TYPE, which is now used to make the getfsstat link test tighter. 2001-09-30 Jim Meyering * lib/mountlist.c [MOUNTED_GETFSSTAT]: Include , for Apple Darwin. Include sys/mount.h and sys/fs_types.h only if available. (FS_TYPE): Define. (read_filesystem_list): Use FS_TYPE. 2001-09-29 Paul Eggert * lib/exclude.c (excluded_filename): 0 -> false, since it's a boolean context. 2001-09-29 Jim Meyering * m4/ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS) [one-argument getmntent function]): Include stdio.h before mntent.h. SunOS 4.1.x needs it for the declaration of `FILE'. Patch by Volker Borchert. * m4/ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS) Check for these headers: sys/param.h sys/ucred.h sys/mount.h sys/fs_types.h, and make the link-test for getfsstat guard #include directives with appropriate #if HAVE_*_H tests so that we can detect getfsstat on Apple Darwin1.3.7 systems. Reported by Nelson Beebe. Fix harmless typo in cache variable name: s/getsstat/getfsstat/. 2001-09-28 Paul Eggert Fix bug reported by Petter Reinholdtsen for HP-UX 10.20, which #defines strtoimax. Also treat the other strto* functions like strtoimax. * m4/xstrtoimax.m4 (jm_AC_PREREQ_XSTRTOIMAX): Check for strtoul and strtoumax, as those declarations are made even in the signed case. * m4/xstrtoumax.m4 (jm_AC_PREREQ_XSTRTOUMAX): Likewise, for strtol and strtoimax. 2001-09-28 Paul Eggert Fix bug reported by Petter Reinholdtsen for HP-UX 10.20, which #defines strtoimax. Also treat the other strto* functions like strtoimax. * lib/xstrtol.c (strtol): Do not declare if HAVE_DECL_STRTOL. (strtoul): Do not declare if HAVE_DECL_STRTOUL. (strtoimax, strtoumax): Do not declare if already defined as a macro. 2001-09-26 Jim Meyering Most macros in unlocked-io.h had the wrong number of arguments. * lib/gen-uio: New script. (USE_UNLOCKED_IO): Define to 1 if not already defined. * lib/unlocked-io.hin: Remove file. * lib/Makefile.am (unlocked-io.h): Rewrite to use a separate script, rather than trying to embed it here. (EXTRA_DIST): Add gen-uio. Remove unlocked-io.hin Reported by Padraig Brady. 2001-09-25 Volker Borchert * lib/gettimeofday.c (rpl_gettimeofday): Declare local variable `result'. 2001-09-24 Jim Meyering * m4/gettext.m4: Use the version from gettext-0.10.40, not CVS. 2001-09-23 Jim Meyering * m4/ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS): Add a compile-test instead of the mere test for existence of mntent.h. The latter would get a false-positive on AIX 3.4 systems. In the outer getmntent if-block, don't die if neither of the getmntent tests succeeds. Instead, just fall through and continue with the remaining tests. 2001-09-23 Jim Meyering * lib/mountlist.c: Remove useless parentheses in #if directives. (MOUNTED) [!defined MOUNTED]: Define to _PATH_MOUNTED, for when the deprecated MOUNTED symbol is no longer defined in mntent.h. 2001-09-22 Jim Meyering * m4/gettext.m4: New file. From gettext. * m4/lcmessage.m4: Sync with gettext -- this changes only comments. * m4/progtest.m4: Likewise * m4/isc-posix.m4: Decrement serial number to sync with gettext. * m4/glibc21.m4: Likewise. * m4/libintl.m4: Remove. No longer used. 2001-09-22 Jim Meyering * lib/localcharset.c: Update from latest gettext. * lib/config.charset: Likewise. 2001-09-20 Jim Meyering * m4/xstrtoimax.m4 (jm_AC_PREREQ_XSTRTOIMAX): Check for declaration of strtoimax. * m4/xstrtoumax.m4 (jm_AC_PREREQ_XSTRTOUMAX): Check for declaration of strtoumax. 2001-09-20 Jim Meyering * lib/xstrtol.c (strtoimax): Guard declaration with `#if !HAVE_DECL_STRTOIMAX', rather than just `#ifndef strtoimax'. The latter fails because some systems (at least rs6000-ibm-aix4.3.3.0) have their own, conflicting declaration of strtoimax in sys/inttypes.h. (strtoumax): Likewise, for completeness (it wasn't necessary). 2001-09-17 Paul Eggert * lib/strtoimax.c (HAVE_LONG_LONG): Redefine to HAVE_UNSIGNED_LONG_LONG if unsigned. (strtoimax): Use sizeof (long), not sizeof strtol (ptr, endptr, base), to work around bug in IBM C compiler. 2001-09-17 Jim Meyering * m4/chown.m4, fstypename.m4, getgroups.m4, gettimeofday.m4, * m4/jm-mktime.m4, lstat.m4, malloc.m4, memcmp.m4, mkdir-slash.m4, * m4/nanosleep.m4, putenv.m4, readdir.m4, realloc.m4, rename.m4, * m4/st_dm_mode.m4, stat.m4, strerror_r.m4, timespec.m4, utimbuf.m4, * m4/utimes.m4: Use AC_DEFINE rather than AC_DEFINE_UNQUOTED, whenever the right hand side need not be expanded by the shell. 2001-09-16 Paul Eggert * m4/fnmatch.m4 (jm_FUNC_FNMATCH): Remove test for GNU C library. It's not correct, as some older glibcs are buggy. fnmatch wasn't fixed until glibc 2.2. Use AC_DEFINE, not AC_DEFINE_UNQUOTED, as there's no special shell magic here. 2001-09-16 Jim Meyering * m4/mkdir-slash.m4 (UTILS_FUNC_MKDIR_TRAILING_SLASH): New file/macro. * m4/jm-macros.m4: Require it. 2001-09-16 Jim Meyering * lib/mkdir.c: New file. 2001-09-15 Jim Meyering * m4/jm-macros.m4: Check for help2man. 2001-09-11 Jim Meyering * m4/host-os.m4 (UTILS_HOST_OS): New file/macro. The body, by Paul Eggert, was moved here from configure.in. * m4/jm-macros.m4: Require UTILS_HOST_OS. 2001-09-04 Paul Eggert * m4/prereq.m4 (jm_PREREQ_XREADLINK): New macro. (jm_PREREQ): Use it. 2001-09-04 Paul Eggert * lib/xreadlink.c (xreadlink): Omit size_t* arg. All uses changed. Use ssize_t, not int, to store result of readlink. Check for ssize_t overflow as well as size_t overflow, as POSIX says the result of readlink is implementation-defined when ssize_t overflows. Remove unnecessary cast to char*. Use free+malloc instead of realloc, as the storage doesn't need to be preserved and it's clearer and can be more efficient that way. (SIZE_MAX, SSIZE_MAX): New macros, if doesn't declare. * lib/xreadlink.h (xreadlink): Update prototype. 2001-09-04 Paul Eggert * lib/xgetcwd.c: Revert some of the previous change; intead, fix the HAVE_GETCWD_NULL code to behave more like the !HAVE_GETCWD_NULL code used to. Include "xalloc.h". (xgetcwd): Do not return NULL when memory is exhausted; instead, invoke xalloc_die. 2001-09-03 Paul Eggert * m4/prereq.m4 (jm_PREREQ_XGETCWD): Check for limits.h and sys/param.h, as pathmax.h includes them. 2001-09-03 Paul Eggert * m4/prereq.m4 (jm_PREREQ): Add jm_PREREQ_XGETCWD. (jm_PREREQ_XGETCWD): New macro. * m4/getcwd.m4: New file. 2001-09-03 Paul Eggert * lib/xgetcwd.c: Fix the !HAVE_GETCWD_NULL code to behave more like the HAVE_GETCWD_NULL code. Include pathmax.h if not HAVE_GETCWD. Do not include xalloc.h. (INITIAL_BUFFER_SIZE): New symbol. Do not use xmalloc / xrealloc, since the caller is responsible for handling errors. Preserve errno around `free' during failure. Do not overrun buffer when using getwd. 2001-09-03 Paul Eggert * lib/xgetcwd.c (xgetcwd): Use HAVE_GETCWD_NULL, not (defined __GLIBC__ && __GLIBC__ >= 2), to decide whether to use getcwd (NULL, 0). 2001-09-03 Paul Eggert * lib/exclude.c (fnmatch_no_wildcards): Fix confusion between usage of FNM_CASEFOLD and FNM_LEADING_DIR. The bug was spotted by Jim Meyering. 2001-09-03 Jim Meyering * lib/xreadlink.c (xreadlink): Preserve errno around `free' during failure. 2001-09-02 Jim Meyering * lib/error.c: Update from GNU libc. 2001-09-01 Jim Meyering * m4/jm-macros.m4 (jm_MACROS): Check for canonicalize_file_name. Used by df. 2001-09-01 Jim Meyering * lib/xreadlink.c: New file. * lib/xreadlink.h: New file. * lib/Makefile.am (libfetish_a_SOURCES): Add xreadlink.c and xreadlink.h. * lib/regex.c (uintptr_t) [!_LIBC]: Define to private_uintptr_t, so it doesn't conflict with sparc Solaris 7's definition in /usr/include/sys/int_types.h. * lib/exclude.c: Use `""', not `<>' to #include non-system header files. (fnmatch_no_wildcards): Rewrite not to use function names, strcasecmp and strncasecmp as r-values. Unixware didn't have declarations. 2001-08-31 Paul Eggert * lib/xstrtol.h: Add copyright notice. (_DECLARE_XSTRTOL): Improve quality of diagnostic for LONGINT_INVALID_SUFFIX_CHAR. 2001-08-31 Paul Eggert * lib/xstrtol.c (strtoimax): New decl. 2001-08-31 Paul Eggert * lib/xgetcwd.c: Don't include pathmax.h. Include stdlib.h and unistd.h if available. Include xalloc.h. (xmalloc, xstrdup, free): Remove decls. (xgetcwd): Don't assume sizes fit in unsigned. Check for overflow when computing sizes. Simplify reallocation code. 2001-08-31 Paul Eggert * lib/savedir.c (savedir): Remove size parameter, as POSIX says that a directory's st_size can have an arbitrary value, so the old usage could waste an arbitrary amount of memory. All uses changed. * lib/savedir.h: Update prototype. 2001-08-31 Paul Eggert * lib/Makefile.am (libfetish_a_SOURCES): Remove strtoxmax.c. * lib/strtoimax.c: Renamed from strtoxmax.c, removing the old strtoimax.c. Also, make the following further changes to make this file's configuration more similar to that of strtol.c: (UNSIGNED): Renamed from STRTOUXMAX_UNSIGNED. All uses changed. (strtoumax, uintmax_t, strtoull, strtol): Remove. (intmax_t, strtoimax, strtol, strtoll): New macros, if UNSIGNED. (strtoimax): Renamed from strtoumax. All uses of unsigned values changed to signed values. And make the following changes as well: Fix copyright notice, as 1999 was missing. (verify): New macro. (strtoimax): Check sizes at compile-time, not run-time. Prefer strtol to strtoll if both work. (main): Remove; it was not that useful and was a pain to maintain. * lib/strtoumax.c: Include strtoimax.c, not strtouxmax.c. 2001-08-31 Jim Meyering * lib/xgetcwd.c (xgetcwd): Reorganize to avoid some duplication. Use an initial, malloc'd, buffer of length 128 rather than a statically allocated one of length 1024. 2001-08-30 Paul Eggert Simplify code, partly by assuming autoconf 2.52 semantics. * m4/Makefile.am (EXTRA_DIST): Remove uintmax_t.m4. * m4/inttypes.m4 (AC_PREREQ): Bump to 2.52. (jm_AC_HEADER_INTTYPES_H): Remove; now done by autoconf in 2.52. All uses removed. (jm_AC_TYPE_INTMAX_T, jm_AC_TYPE_UINTMAX_T): Move AC_REQUIRE to next-to-top level, to avoid confusion. Use 2.52's AC_CHECK_TYPE instead of merely looking for the header. * m4/prereq.m4 (jm_PREREQ_HUMAN): Don't require jm_AC_HEADER_INTTYPES_H. * m4/jm-macros.m4 (jm_MACROS): Likewise. * m4/uintmax_t.m4: Remove, as it duplicates inttypes.m4. * m4/xstrtoimax.m4 (jm_AC_PREREQ_XSTRTOIMAX): Quote first arg of AC_DEFUN. Require jm_AC_TYPE_UINTMAX_T and jm_AC_TYPE_UNSIGNED_LONG_LONG since they are needed to parse the include file even if we need only xstrtoimax. Simplify logic behind the args to AC_REPLACE. * m4/xstrtoumax.m4 (jm_AC_PREREQ_XSTRTOUMAX): Likewise, but with opposite signedness. 2001-08-30 Paul Eggert Merge 'exclude' changes from tar 1.13.22. This fixes one or two unlikely storage allocation overflow bugs, but doesn't change user-visible behavior otherwise. 2001-08-30 Paul Eggert * m4/prereq.m4 (jm_PREREQ): Add jm_PREREQ_EXCLUDE. (jm_PREREQ_EXCLUDE): New macro. 2001-08-30 Paul Eggert * lib/quotearg.c: BSD/OS 4.1 wchar.h requires FILE and struct tm to be declared. 2001-08-30 Paul Eggert * lib/hash.c: Remove '2001' from copyright notice. 2001-08-30 Paul Eggert * lib/full-write.h: New file. * lib/Makefile.am (libfetish_a_SOURCES): Add full-write.h. * lib/full-write.c: Correct credits, as cccp.c no longer exists and anyway it was so heavily changed from the old cccp code as to be unrecognizable. Include full-write.h. (full_write): Return size_t, with short writes meaning failure. All callers changed. This fixes a bug with large buffers on 64-bit hosts. * lib/utime.c: Include full-write.h. 2001-08-30 Paul Eggert * lib/exclude.c (bool): Declare, perhaps by including stdbool.h. (): Include only if HAVE_SYS_TYPES_H. (, , , , ): Include if available. (): Include (SIZE_MAX): Define if or doesn't. (verify): New macro. Use it to verify that EXCLUDE macros do not collide with FNM macros. (struct patopts): New struct. (struct exclude): Use it, as exclude patterns now come with options. (new_exclude): Support above changes. (new_exclude, add_exclude_file): Initial size must now be a power of two to simplify overflow checking. (free_exclude, fnmatch_no_wildcards): New function. (excluded_filename): No longer requires options arg, as the options are determined by add_exclude. Now returns bool, not int. (excluded_filename, add_exclude): Add support for the fancy new exclusion options. (add_exclude, add_exclude_file): Now takes int options arg. Check for arithmetic overflow when computing sizes. (add_exclude_file): xrealloc might modify errno, so don't realloc until after errno might be used. * lib/exclude.h (EXCLUDE_ANCHORED, EXCLUDE_INCLUDE,EXCLUDE_WILDCARDS): New macros. (free_exclude): New decl. (add_exclude, add_exclude_file): Now takes int options arg. (excluded_filename): No longer requires options arg, as the options are determined by add_exclude. Now returns bool, not int. 2001-08-30 Paul Eggert * lib/alloca.c (alloca): Arg is of type size_t, not unsigned. 2001-08-27 Jim Meyering * lib/Makefile.am (libfetish_a_SOURCES): Add strtoxmax.c * lib/version-etc.c (N_): Remove definition. Revert most of last change. Instead, simply don't mark the `Copyright...' string for translation. Based on advice from Paul Eggert. * lib/strtoxmax.c: Tweak comment. 2001-08-26 Jim Meyering * m4/jm-macros.m4: Require jm_AC_PREREQ_XSTRTOIMAX. * m4/xstrtoimax.m4: New file. * m4/xstrtoumax.m4: Add comments explaining why we AC_REPLACE_FUNCS(strtol). 2001-08-26 Jim Meyering * lib/version-etc.c (version_etc_copyright_fmt): Replace literal year of copyright with `%s' so translators don't get an untranslated message in 2002. (COPYRIGHT_YEAR): Define. (version_etc): Use fprintf rather than fputs. Suggestion from Ulrich Drepper. * lib/Makefile.am (libfetish_a_SOURCES): Add xstrtoimax.c. * lib/strtoll.c: New file, from GNU libc. * lib/xstrtoimax.c: New file. * lib/xstrtol.h: Add xstrtoimax. * lib/strtoumax.c: New file. Simply include "strtoumax.c". * lib/strtoimax.c: New file. Likewise, but first define STRTOUXMAX_SIGNED. * lib/strtoumax.c: Factor to work both for unsigned and signed types, ... * lib/strtoxmax.c: ... then renamed to this. 2001-08-18 Paul Eggert * m4/inttypes.m4: Add AC_PREREQ(2.13). (jm_AC_HEADER_INTTYPES_H): Test for intmax_t, too. (jm_AC_TYPE_INTMAX_T): New macro. (jm_AC_TYPE_UINTMAX_T): Moved here from uintmax_t.m4. * m4/longlong.m4 (jm_AC_TYPE_LONG_LONG): New macro. * m4/longlong.m4: Renamed from ulonglong.m4. * m4/inttypes.m4: Renamed from inttypes_h.m4. * m4/uintmax_t.m4: Removed. 2001-08-13 Paul Eggert * lib/Makefile.am (unlocked-io.h): Do not append "_unlocked" twice. Port to Solaris 8, where 'sed' requires a space after the 'r' command, and where sh dislikes "$/". Clean up the spacing a bit. Redirect output to $tmp just once. 2001-08-12 Paul Eggert * lib/addext.c (): Include. (errno): Declare if not defined. (addext): Work correctly when pathconf returns -1 and leaves errno alone because there is no limit. Also, work even if pathconf returns a value greater than SIZE_MAX. 2001-08-12 Jim Meyering * m4/afs.m4, assert.m4, bison.m4, check-decl.m4, chown.m4, d-ino.m4, d-type.m4, dos.m4, error.m4, fnmatch.m4, fpending.m4, fstypename.m4, fsusage.m4, ftruncate.m4, getgroups.m4, glibc.m4, gnu-source.m4, group-member.m4, jm-glibc-io.m4, jm-macros.m4, jm-mktime.m4, jm-winsz1.m4, jm-winsz2.m4, lchown.m4, lib-check.m4, libintl.m4, link-follow.m4, ls-mntd-fs.m4, lstat.m4, malloc.m4, mbrtowc.m4, mbstate_t.m4, mbswidth.m4, memcmp.m4, nanosleep.m4, perl.m4, prereq.m4, putenv.m4, readdir.m4, realloc.m4, regex.m4, rename.m4, rmdir-errno.m4, search-libs.m4, st_dm_mode.m4, st_mtim.m4, stat.m4, strftime.m4, timespec.m4, unlink-busy.m4, uptime.m4, utimbuf.m4, utime.m4, utimes.m4, xstrtoumax.m4: Quote the first argument in each use of AC_DEFUN. 2001-08-12 Jim Meyering * lib/xgetcwd.c (xgetcwd) [defined __GLIBC__ && __GLIBC__ >= 2]: Simply `return getcwd (NULL, 0);'. [! (defined __GLIBC__ && __GLIBC__ >= 2)]: Use 1300 as initial value for length, not PATH_MAX. * lib/pathmax.h: Clean up cpp syntax. 2001-08-12 Jim Meyering * lib/gettimeofday.c: New file. * lib/gtod.h: New file. * lib/Makefile.am (libfetish_a_SOURCES): Add gtod.h. 2001-08-05 Jim Meyering * m4/jm-macros.m4: Require autoconf-2.52. 2001-08-04 Jim Meyering * lib/error.h (__attribute__): Remove `|| __STRICT_ANSI__' from #if stmt, to get in sync with glibc. 2001-08-03 Paul Eggert The following changes are from gettext 0.10.39 as maintained by Bruno Haible. * lib/mbswidth.h (MBSW_REJECT_UNPRINTABLE, MBSW_REJECT_INVALID): Renamed from MBSW_ACCEPT_UNPRINTABLE and MBSW_ACCEPT_INVALID with inverted sense. All uses changed. * lib/mbswidth.c: Don't include . Include and unconditionally. (iswcntrl, mbsinit, ISCNTRL): New macros. (mbsnwidth): Use K&R style function declarations. Don't bother checking for MB_LEN_MAX == 1, since the compiler can optimize it when MB_CUR_MAX == 1. The width of control characters is zero, not 1. 2001-08-03 Paul Eggert The following changes are from gettext 0.10.39 as maintained by Bruno Haible, except that getline.m4 continues to use AC_LIBOBJ. * m4/codeset.m4: Upgrade to serial AM1. (AM_LANGINFO_CODESET): Renamed from jm_LANGINFO_CODESET; all uses changed. Quote first arg of AC_DEFUN. (am_cv_langinfo_codeset): Renamed from jm_cv_langinfo_codeset. * m4/iconv.m4: Upgrade to serial AM2. (AM_ICONV): Renamed from jm_ICONV; all uses changed. Add --with-libconv-prefix. Quote first arg of AC_DEFUN. Add description for ICONV_CONST. (am_cv_func_iconv): Renamed from jm_cv_func_iconv. (am_cv_lib_iconv): Renamed from jm_cv_lib_iconv. (am_cv_proto_iconv): Renamed from jm_cv_proto_iconv. * m4/jm-macros.m4 (jm_MACROS): Reflect s/jm_/AM_/ renamings. * m4/c-bs-a.m4 (AC_C_BACKSLASH_A): Quote first arg of AC_DEFUN. * m4/getline.m4 (AM_FUNC_GETLINE): Likewise. * m4/glibc21.m4 (jm_GLIBC21): Likewise. * m4/inttypes_h.m4 (jm_AC_HEADER_INTTYPES_H): Likewise. * m4/isc-posix.m4 (AC_ISC_POSIX): Likewise. * m4/lcmessage.m4 (AM_LC_MESSAGES): Likewise. * m4/progtest.m4 (AM_PATH_PROG_WITH_TEST): Likewise. * m4/uintmax_t.m4 (jm_AC_TYPE_UINTMAX_T): Likewise. * m4/ulonglong.m4 (jm_AC_TYPE_UNSIGNED_LONG_LONG): Likewise. * m4/getline.m4 (AM_FUNC_GETLINE): Don't bother checking for string.h any more. * m4/progtest.m4 (AM_PATH_PROG_WITH_TEST): If not found, print "no", not the default value. 2001-06-25 Bruno Haible * m4/mbswidth.m4 (jm_PREREQ_MBSWIDTH): Don't require AM_C_PROTOTYPES. Also check for mbsinit. Needed for SCO 3.2v5.0.2. Also include ; this is where AIX 3.2.5 declares wcwidth. Also check for iswcntrl, used for wcwidth fallback. Use AC_TRY_COMPILE to emulate AC_CHECK_DECLS, for portability to Autoconf 2.13. 2001-08-03 Jim Meyering * m4/mbrtowc.m4 (jm_FUNC_MBRTOWC): Use `#include', not `@%:@include', as it was in the original. Reported by Paul Eggert. 2001-07-16 Jim Meyering * m4/gettimeofday.m4: New file. Prompted by a report from Bernhard Baehr. 2001-07-15 Jim Meyering * m4/Makefile.am.in (Makefile.am): Remove most of the unlocked-io.h stuff. Now it's in ../Makefile.cfg. 2001-07-15 Jim Meyering * lib/Makefile.am (EXTRA_DIST): Add unlocked-io.hin. (BUILT_SOURCES): Add unlocked-io.h. (io_functions): Define. (unlocked-io.h): New rule. (DISTCLEANFILES): Add unlocked-io.h. (all-local): Depend on unlocked-io.h, to ensure it is created. * lib/unlocked-io.hin: New file * lib/regex.c: Update from glibc. 2001-07-05 Jim Meyering * lib/Makefile.am (noinst_HEADERS): Remove definition, per new automake recommendation. (libfetish_a_SOURCES): Put all .h files here instead. Remove a thus-exposed (better checks in automake) duplicate and two unnecessary .h files. 2001-07-04 Jim Meyering * m4/Makefile.am.in (glibc-io.struct): New target. Rework the code that generates jm-glibc-io.m4 so that it doesn't trigger any make distcheck failure. 2001-07-02 Jim Meyering The following changes were prompted by suggestions from Bruno Haible. * m4/jm-glibc-io.m4n: New file, the template from which jm-glibc-io.m4 is now generated. * m4/Makefile.am.in (Makefile.am): Include jm-glibc-io.m4n in emitted definition of EXTRA_DIST. (Makefile.am): Emit the dependency, `all-local: jm-glibc-io.m4' to ensure that the generated file is created/updated whenever the list of $(unlocked_functions) is changed. (jm-glibc-io.m4): New rule. (unlocked-io.h): New rule -- currently unused. 2001-06-24 Jim Meyering * m4/regex.m4 (jm_INCLUDED_REGEX): Use a quadrigraph to represent an unmatched right bracket, rather than kludging it with an extra, falsely-matching quote in a comment. Patch by Akim Demaille. 2001-06-11 Jim Meyering * lib/regex.c: Update from GNU libc. 2001-05-27 Jim Meyering * m4/prereq.m4 (jm_PREREQ_READUTMP): Check for ut_type in struct utmpx. Check for ut_type in struct utmp. 2001-05-27 Jim Meyering * lib/readutmp.h (UT_TYPE): Define. 2001-05-24 Jim Meyering * lib/argmatch.c: Include "quote.h". (argmatch_invalid): Remove explicit `' quotes. Instead, use the quote function. Reported by Göran Uddeborg. 2001-05-22 Jim Meyering * m4/strftime.m4 (_jm_STRFTIME_PREREQS): Don't use AC_LIBOBJ(strftime), now that we use the package-supplied version unconditionally. (jm_FUNC_STRFTIME): Don't replace strftime, for the same reason. 2001-05-21 Jim Meyering * m4/regex.m4: Change a couple backticks to single quotes to avoid shell syntax errors. 2001-05-21 Alexandre Duret-Lutz * m4/dos.m4 (jm_AC_DOS): Check for _WIN32, __WIN32__, and __MSDOS__. 2001-05-20 Paul Eggert * m4/strftime.m4 (jm_FUNC_GNU_STRFTIME): Don't bother to check library strftime, since we'll be using our own my_strftime function anyway. Define my_strftime instead of strftime. 2001-05-20 Alexandre Duret-Lutz * lib/dirname.c (dir_name): Compute append_dot using path, not newpath which is not yet declared. 2001-05-15 Jim Meyering * m4/regex.m4: Use proper quoting so brackets appear in the test program. Reported by, and with help from, Bruno Haible. 2001-05-13 Jim Meyering * m4/jm-macros.m4 (major_t, minor_t): Define to unsigned int if undefined. 2001-05-11 Paul Eggert dirname code cleanup. base_name now behaves more compatibly with POSIX basename when given file names that have trailing slashes, and similarly for dir_name. Add new primitives base_len and dir_len. Put the directory-name-related decls into dirname.h. * lib/addext.c (ISSLASH, base_name): Remove; now in dirname.h. * lib/backupfile.c (base_name): Likewise. * lib/basename.c (FILESYSTEM_PREFIX_LEN, PARAMS, ISSLASH): Likewise. * lib/dirname.c (FILESYSTEM_PREFIX_LEN, ISSLASH): Likewise. * lib/makepath.c (strip_trailing_slashes): Likewise. * lib/path-concat.c (DIRECTORY_SEPARATOR, FILESYSTEM_PREFIX_LEN, ISSLASH): Likewise. * lib/rename.c (strip_trailing_slashes): Likewise. * lib/same.c (base_name): Likewise. * lib/stripslash.c (ISSLASH): Likewise. * lib/addext.c: Include after size_t is defined. * lib/backupfile.c: Likewise. * lib/addext.c (addext): Use base_len to trim redundant trailing slashes instead of doing it ourselves. But do not trim the last slash if it is not redundant. * lib/backupfile.c (find_backup_file_name, max_backup_version): Use base_len instead of rolling it ourselves. Handle the case of "" and (on DOS) "C:" correctly. * lib/basename.c: Do not include , ; no longer needed. Include , . (base_name): Allow file names ending in slashes, other than names that are all slashes. In this case, return the basename followed by the slashes. This is more general, and can be used in places where the original base_name purposely had an assertion failure. (base_len): New function. * lib/dirname.c: Include instead of . Do not include ; no longer needed. Include xalloc.h. (memrchr): Remove decl. (dir_name_r): Remove. (dir_len): Renamed from dirlen. All callers changed. Rewrite in terms of base_name, for simplicity and consistency. (dir_name): Never return NULL. All callers changed. Do not include in test program; no longer needed. return 0; is fine for test program. * lib/dirname.h (DIRECTORY_SEPARATOR, ISSLASH, FILESYSTEM_PREFIX_LEN): New macros. (base_name, base_len, dir_len, strip_trailing_slashes): New decls. * lib/path-concat.c (path_concat): Use base_len to compute base length, not strlen; this means we cannot rely on memcpy to null-terminate. * lib/same.c (STREQ): Remove. (same_name): Handle the case where the basename ends in trailing '/'. * lib/stripslash.c (strip_trailing_slashes): Return nonzero if a slash was stripped. Do not strip the last slash after a file system prefix. 2001-05-11 Paul Eggert * lib/Makefile.am (libfetish_a_SOURCES): Add strftime.c, since we now compile it on all hosts. * lib/strftime.c (my_strftime): Define to nstrftime if emacs, but only if my_strftime is not defined. (extra_args, extra_args_spec, extra_args_spec_iso): Rename from ut_argument, ut_argument_spec, ut_argument_spec_iso, respectively. Add one more extra argument: a nanoseconds value. All uses changed. (ns): New macro. (my_strftime function): Add %N format. (emacs_strftimeu): Renamed from emacs_strftime, with extra ut argument. 2001-05-09 Paul Eggert * m4/jm-macros.m4 (jm_MACROS): Do not check for fseeko; no longer used. 2001-04-21 Jim Meyering * m4/rmdir-errno.m4: Write to a new file, so that a restrictive umask doesn't interfere. 2001-04-21 Alexandre Duret-Lutz * m4/ftruncate.m4: Check for chsize. Link with ftruncate.o unconditionally if ftruncate is missing. This was required when cross-compiling to i586-mingw32msvc. 2001-04-08 Jim Meyering * lib/getdate.y (get_date): Set tm_isdst to -1 to ensure that it is recomputed; that's necessary when the offset spans a DST transition. Patch by David J. MacKenzie. Reported by Hon-Yin Kok. 2001-04-02 Jim Meyering * lib/regex.h, regex.c: Update from GNU libc. 2001-03-24 Jim Meyering * m4/jm-macros.m4: Require autoconf-2.49d. 2001-03-20 Bruno Haible * m4/iconv.m4 (jm_ICONV): Recommend GNU libiconv. 2001-03-19 Paul Eggert * lib/version-etc.c (version_etc_copyright): Update to 2001. 2001-03-17 Jim Meyering * m4/memcmp.m4 (jm_AC_FUNC_MEMCMP): Remove my copy of AC_FUNC_MEMCMP, now that the version in autoconf is equivalent. (jm_FUNC_MEMCMP): Adjust to use AC_FUNC_MEMCMP. * m4/error.m4 (jm_PREREQ_ERROR): Invoke AC_FUNC_STRERROR_R. Suggestion from Akim Demaille. * m4/prereq.m4 (jm_PREREQ): Add jm_PREREQ_TEMPNAME. (jm_PREREQ_TEMPNAME): New function. 2001-03-16 Paul Eggert * lib/tempname.c (uint64_t): Define to uintmax_t if not defined, and if UINT64_MAX is not defined. Required at least for Vax Ultrix4.3, which doesn't define uint64_t. Reported by John David Anglin. 2001-03-15 Bruno Haible * lib/localcharset.c (locale_charset): Allow wildcard syntax. Also resolve alias if codeset is empty. * lib/config.charset (BeOS): Use wildcard syntax. 2001-03-13 Jim Meyering * lib/path-concat.c (path_concat) [FILESYSTEM_ACCEPTS_DRIVE_LETTER_PREFIX]: Don't insert a backslash when concatenating e.g., `C:' and `foo'. From Bruno Haible. 2001-03-06 Bruno Haible * lib/localcharset.c (locale_charset): Don't use setlocale(LC_CTYPE,NULL). Don't return NULL. * lib/unicodeio.c (print_unicode_char): Simplify accordingly. 2001-03-06 Bruno Haible * lib/config.charset: Update for FreeBSD 4.2 and OSF/1 5.1. Add support for DOS/DJGPP. 2001-03-01 Paul Eggert * m4/jm-macros.m4 (jm_MACROS): Use mkstemp replacement if the system lacks mkstemp. Compile our own tempname.c if we compile our own mkstemp.c, as mkstemp relies on tempname. 2001-03-01 Jim Meyering * m4/dos.m4 (jm_AC_DOS): Remove extra backslashes, now that AH_VERBATIM really does output its argument verbatim. 2001-02-28 Paul Eggert * lib/Makefile.am (libfetish_a_SOURCES): Add dup-safer.c, fopen-safer.c. (noinst_HEADERS): Add stdio-safer.h, unistd-safer.h. * lib/dup-safer.c, lib/fopen-safer.c, lib/stdio-safer.h: * lib/unistd-safer.h: New files. 2001-02-25 Paul Eggert The mkstemp replacement is taken from glibc 2.2.2, with some portability fixes for use outside glibc, as follows: * lib/tempname.c (struct_stat64): New macro. (direxists, __gen_tempname): Use it. This avoids a portability problem with Solaris 8. * lib/tempname.c (): Include if HAVE_CONFIG_H. (, , ): Include only if STDC_HEADERS || _LIBC.

Ignore S_ISDIR if STAT_MACROS_BROKEN. (stat64, __getpid, __gettimeofday, __mkdir, __open, __open64, lxstat64, __xstat64): Define if not _LIBC. (__secure_getenv): Define if ! (HAVE___SECURE_GETENV || _LIBC). (__gen_tempname): Invoke gettimeofday only if HAVE_GETTIMEOFDAY || _LIBC; otherwise, fall back on plain "time". Use macros like S_IRUSR | S_IWUSR rather than octal values like 0600. * lib/mkstemp.c (__GT_FILE): Define to zero if not defined. * lib/mkstemp.c, lib/tempname.c: New files, taken from glibc 2.2.2. 2001-02-18 Paul Eggert * m4/jm-macros.m4 (jm_CHECK_ALL_HEADERS): Check for sys/resource.h. 2001-02-17 Paul Eggert * m4/mbrtowc.m4: New file, defining jm_FUNC_MBRTOWC. * m4/mbswidth.m4 (jm_PREREQ_MBSWIDTH): Use jm_FUNC_MBRTOWC, not AC_CHECK_FUNCS(mbrtowc). * m4/prereq.m4 (jm_PREREQ_QUOTEARG): Likewise. 2001-02-17 Paul Eggert * lib/mbswidth.c, quotearg.c (mbrtowc, mbsinit): Remove workaround macros for hosts that have mbrtowc but not mbstate_t, as we now insist on proper declarations for both before using mbrtowc. 2001-02-17 Jim Meyering * m4/ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS): Don't check for getmntent via AC_CHECK_FUNCS, since that would get a `no' and disrupt further attempts by AC_FUNC_GETMNTENT to check with e.g., -lgen on UnixWare 7.1.1. * m4/mbrtowc.m4 (jm_FUNC_MBRTOWC): Adapt to use AC_CACHE_CHECK etc., rather than AC_CACHE_VAL. 2001-02-17 Jim Meyering * lib/strtoul.c: Sync from GNU libc. Use double quotes, not <...> around included file name. * lib/strnlen.c (__strnlen): Merge in a change from GNU libc. * lib/strftime.c: Update from GNU libc (the only changes were to comments). 2001-02-17 Jim Meyering * lib/regex.c: Update from libc. 2001-02-17 Bruno Haible * lib/mbswidth.h (mbswidth): Also define as macro, to avoid prototype clash. 2001-02-16 Paul Eggert * lib/alloca.c (malloc): Undef before defining, since stdlib.h may have defined it. Needed for Encore Umax-3.0.9.16b systems. Reported by Mark Hounschell via Paul Eggert. 2001-02-07 Jim Meyering * m4/regex.m4 (jm_INCLUDED_REGEX): Add a test for the latest bug. 2001-02-05 Jim Meyering * m4/jm-macros.m4: Require autoconf-2.14d (not yet released), because it includes the patch required for `large file' support with at least HP-UX's 10.20 /bin/cc. 2001-02-03 Jim Meyering * m4/ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS): Restore prior use of AS_IF, now that it works once again (mysteriously). * m4/fsusage.m4 (jm_FILE_SYSTEM_USAGE): Likewise. 2001-01-30 Jim Meyering Don't use filenames that are 8.3-equivalent to "conftest" on DOS. * m4/chown.m4: Rename conftestchown to conftest.chown. * m4/rename.m4: s/conftestdir/conftest.d1/ and s/conftestdir2/conftest.d2/. * m4/utimes.m4: s/conftestdata/conftest.data/ Inspired by Pavel Roskin's change in autoconf. 2001-01-30 Bruno Haible * lib/config.charset: Update for FreeBSD 4.2. 2001-01-27 Jim Meyering * m4/ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS): Open-code what was a use of AS_IF. * m4/fsusage.m4 (jm_FILE_SYSTEM_USAGE): Likewise. 2001-01-26 Jim Meyering * m4/prereq.m4 (jm_PREREQ_QUOTEARG): Check for stddef.h, now that quotearg.c includes it. 2001-01-26 Jim Meyering * lib/quotearg.c: Include stddef.h. * lib/quote.c: Include stddef.h.

[HAVE_DONE_WORKING_REALLOC_CHECK]: Likewise. Reported by Axel Kittenberger. 2001-01-24 Stefan Monnier * regex.c (mutually_exclusive_p): Don't blindly handle `charset_not' as if it was a `charset'. 2001-01-21 Bruno Haible * m4/iconv.m4 (jm_ICONV): Also check whether the iconv declaration has const. 2001-01-21 Bruno Haible * lib/unicodeio.c (print_unicode_char): Cast the second iconv() arg, to avoid a warning. Add back 'const' to inptr. 2001-01-20 Jim Meyering Be sure that headers are checked before used in code compiled for the type checks. * m4/jm-macros.m4 (jm_MACROS): Remove all header checks. In place of that, invoke jm_CHECK_ALL_TYPES. (jm_CHECK_ALL_HEADERS): New functions with the above checks. (jm_CHECK_ALL_TYPES): Require jm_CHECK_ALL_HEADERS. Alan Iwi reported a build failure on an f300-fujitsu-uxpv4.1_ES; The check for ssize_t was mistakenly run before the test for unistd.h. The configure-time check for stdbool.h was missing. * m4/prereq.m4 (jm_PREREQ): Add jm_PREREQ_HASH. (jm_PREREQ_HASH): New function. 2001-01-17 Jim Meyering * m4/fsusage.m4 (jm_FILE_SYSTEM_USAGE): Use AS_IF, not AS_IFELSE, for autoconf-2.49c. * m4/ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS): Likewise. 2001-01-16 Jim Meyering * lib/basename.c: Include , needed by assert on SunOS 4. From Bruno Haible. 2001-01-14 Jim Meyering * m4/rename.m4: Use temporary directories named conftestdir{,2}, not foo and bar. Create conftestdir/ in the script, not in the C code. Remove directories in the script, not in the C code. Remove conftestdir{,2} before trying to create the directory. Make the entire configure script fail if the mkdir fails. 2001-01-14 Jim Meyering * lib/rename.c: New file. From Volker Borchert. Include stdlib.h, string.h or strings.h, and xalloc.h. Use strip_trailing_slashes rather than open-coding it. 2001-01-03 Paul Eggert * lib/strftime.c: Sync with glibc time/strftime.c 1.81. 2001-01-03 Jim Meyering * lib/unicodeio.c (print_unicode_char): Remove `const' from declaration of local `inptr' to avoid warning with some system declarations of iconv. 2001-01-02 Volker Borchert * m4/rename.m4: New file. * m4/jm-macros.m4 (jm_MACROS): Require vb_FUNC_RENAME. 2001-01-01 Jim Meyering * m4/prereq.m4 (jm_PREREQ_READUTMP): Include utmp.h (if available), even on systems with utmpx.h. It's necessary for the declaration of utmp's ut_user member. Reported by Andreas Jaeger. * m4/check-decl.m4 (jm_CHECK_DECLS): Include grp.h and pwd.h if available. They are required for the declarations of getgrgid and getpwuid resp. (_jm_DECL_HEADERS): Check for grp.h and pwd.h. Reported by Andreas Jaeger. 2001-01-01 Alexandre Duret-Lutz * m4/libintl.m4 (AM_GNU_GETTEXT): Define MKINSTALLDIRS by expanding the value of $ac_aux_dir, as in AM_MISSING_HAS_RUN, so `make install' also works in VPATH builds. 2000-12-31 Alexandre Duret-Lutz * m4/libintl.m4 (AM_WITH_NLS): When using AC_CONFIG_AUX_DIR, prepend $(top_srcdir) to the value of MKINSTALLDIRS so that it can be used in subdirectories. 2000-12-29 Paul Eggert * lib/modechange.c: Do not assume that mode_t uses the traditional octal encoding. E.g. "chmod 1 FOO" should set the other-execute bit of FOO even if S_IXOTH != 1. (SUID, SGID, SVTX, RUSR, WUSR, XUSR, RGRP, WGRP, XGRP, ROTH, WOTH, XOTH, ALLM): New macros. (S_ISUID, S_ISGID, S_ISVTX, S_IRUSR, S_IWUSR, S_IXUSR, S_IRGRP, S_IWGRP, S_IXGRP, S_IROTH, S_IWOTH, S_IXOTH): Use them. (S_ISGID): Fix typo; it was defaulting to the same value as S_ISUID. (S_IRWXU, S_IRWXG, S_IRWXO): Specify defaults in terms of the above. (mode_compile): No need to use uintmax_t; unsigned long is long enough. Don't bother to get suffix since we don't use it. 2000-12-26 Jim Meyering * m4/dos.m4 (jm_AC_DOS): Rewrite (though it's still a stub) to work better with autoheader. 2000-12-24 Jim Meyering * lib/hash.c (is_prime): Return explicit boolean values. (hash_get_first): Return NULL to appease Irix5.6's 89. Reported by Nelson Beebe. 2000-12-19 Bruno Haible * lib/localcharset.c (locale_charset): Add support for Win32. 2000-12-18 Paul Eggert * lib/physmem.h, lib/physmem.c: New files. * lib/Makefile.am (libfetish_a_SOURCES): Add physmem.c.

Include stdlib.h. (ADDITIONAL_DEFAULT_SHELLS): Define. (default_shells): Prepend ADDITIONAL_DEFAULT_SHELLS. Based mostly on a patch from Prashant TR. 2000-12-16 Bruno Haible * lib/config.charset: Add ISO-8859-3, BIG5HKSCS, GB18030, JOHAB, VISCII, CP874, CP949, CP950, CP1250, CP1253, CP1254, CP1255, CP1256, CP1257 to the list of canonical encodings. Rename EUC-CN to GB2312. 2000-12-08 Andreas Schwab * lib/mbswidth.c (mbsnwidth): Don't loop endlessly when called with an invalid mulitbyte sequence and with the MBSW_ACCEPT_INVALID flag set. 2000-12-07 Jim Meyering * lib/stripslash.c (ISSLASH): Define. (strip_trailing_slashes): Use ISSLASH rather than comparing against `/'. From Prashant TR. * lib/dirname.c (FILESYSTEM_PREFIX_LEN): Define. (dir_name_r): Declare this function as static. [BACKSLASH_IS_PATH_SEPARATOR]: Fix a bug that'd manifest itself on a name containing a mix of slashes and backslashes. Make this function work with names starting with a DOS-style drive letter and colon prefix. (dir_name): Append `.' if necessary. Based mostly on patches from Prashant TR and Eli Zaretskii. * lib/dirname.h (dir_name_r): Remove prototype. 2000-12-06 Paul Eggert * m4/off_t-format.m4: Remove this file. * m4/jm-macros.m4 (jm_MACROS): Remove jm_SYS_OFF_T_PRINTF_FORMAT. 2000-12-06 Jim Meyering * m4/xstrtoumax.m4 (jm_AC_PREREQ_XSTRTOUMAX): If we need the replacement strtoull, we may well need the replacement strtoul, too. Check for declarations of strtoul and strtoull. Check for strtol. Mainly as a cue to cause automake to include strtol.c -- that file is included by each of strtoul.c and strtoull.c. Check for limits.h -- strtol.c needs it. 2000-12-05 Jim Meyering * lib/dirname.c (dir_name_r): Add `const' in a few local declarations. 2000-12-04 Jim Meyering * lib/path-concat.c: [!HAVE_DECL_MALLOC]: Declare malloc. Also include memory.h, stdlib.h, unistd.h if appropriate.

From Werner Almesberger. 2000-11-22 Paul Eggert * lib/strftime.c (my_strftime): Do not invoke mbrlen with a size of (size_t) -1; it's not portable. 2000-11-17 Jim Meyering * lib/strstr.c: Update from GNU libc. 2000-11-17 Akim Demaille * lib/obstack.h: Formatting changes. (obstack_grow, obstack_grow0): Don't cast WHERE at all: that would prevent type checking. (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't cast the value to (void *): assigning a `foo *' to a `void *' variable is valid. (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int. 2000-11-16 Jim Meyering * lib/strverscmp.c: Incorporate weak-alias-related changes from glibc. 2000-11-11 Jim Meyering * lib/error.c: Add a couple #includes, merging from GNU libc version. 2000-11-10 Jim Meyering * lib/obstack.h: Update from GNU libc. * lib/obstack.c: Likewise. 2000-11-08 Bruno Haible * m4/jm-macros.m4 (jm_MACROS): Add test for wcrtomb. 2000-11-06 Paul Eggert * lib/getusershell.c (setusershell): Use rewind rather than fseek/fseeko, to avoid configuration hassles with fseeko. Don't bother opening SHELLS_FILE if shellstream is NULL; it's not necessary. 2000-11-05 Jim Meyering * lib/makepath.h (make_dir): Declare. * lib/makepath.c (make_dir): Remove `static' attribute. Tweak a comment. 2000-11-04 Jim Meyering * m4/regex.m4: Use the `m4_' prefix on `syscmd' and `m4_sysval'. 2000-11-04 Alexandre Duret-Lutz * lib/hash.c (hash_get_next): Fix a thinko: when ENTRY is the last one in a bucket, advance to the next bucket. 2000-11-02 Vesselin Atanasov * lib/fnmatch.c: Do not comment out all the code if we are using the GNU C library, because in some cases we are replacing buggy code in the GNU C library itself. 2000-10-30 Stefan Monnier * regex.c (re_iswctype, re_wctype_to_bit): Fix braino. (regex_compile): Catch bogus \(\1\). 2000-10-30 Paul Eggert * lib/fnmatch.c (FOLD): Do not assume that characters are unsigned. (fnmatch): Fix some FNM_FILE_NAME and FNM_LEADING_DIR bugs, e.g. fnmatch("d*/*1", "d/s/1", FNM_FILE_NAME) incorrectly yielded zero. 2000-10-30 Paul Eggert * lib/error.h, getline.h, modechange.h: Remove "2000" from Copyright line, as the file hasn't been changed this year other than in the copyright notice. * lib/xalloc.h: Add "2000" to Copyright line, as this file was changed this year. 2000-10-29 Jim Meyering * m4/fsusage.m4: s/AC_SHELL_IFELSE/AS_IFELSE/ to match autoconf renaming. * m4/ls-mntd-fs.m4: Likewise 2000-10-29 Jim Meyering * lib/xstat.in: Fix grammar in comment. 2000-10-29 Greg Louis * lib/regex.h (__restrict_arr): Move definition out of #ifndef block. Required because egcs-2.91.66 (aka 1.1.2) defines __restrict, but doesn't define __restrict_arr. 2000-10-28 Jim Meyering * m4/prereq.m4 (jm_PREREQ): Add jm_PREREQ_MEMCHR. (jm_PREREQ_MEMCHR): New function. 2000-10-28 Jim Meyering * lib/memchr.c: Update from libc. Adjust for portability: [HAVE_STDLIB_H]: Include stdlib.h.

Avoid using fseek, when possible -- it's broken by design. Patch by Ulrich Drepper. 2000-10-27 Stefan Monnier * regex.c (POP_FAILURE_REG_OR_COUNT, re_match_2_internal) (re_match_2_internal, re_match_2_internal, re_match_2_internal): Giving in to popular pressure to shut up the compiler with casts. 2000-10-26 Jim Meyering * lib/strftime.c: Update from libc. 2000-10-25 Stefan Monnier * regex.c: More `unsigned char' -> `re_char' changes. Also change several `int' into `re_wchar_t'. (PATTERN_STACK_EMPTY, PUSH_PATTERN_OP, POP_PATTERN_OP): Remove. (PUSH_FAILURE_POINTER): Don't cast any more. (POP_FAILURE_REG_OR_COUNT): Remove the cast that strips `const'. We want GCC to complain, since this piece of code makes re_match non-reentrant, which *should* be fixed. (GET_BUFFER_SPACE): Use size_t rather than unsigned long. (EXTEND_BUFFER): Use RETALLOC. (SET_LIST_BIT): Don't cast. (re_wchar_t): New type. (re_iswctype, re_wctype_to_bit): Make it crystal clear to GCC that those two functions will always properly return. (IMMEDIATE_QUIT_CHECK): Cast to void. (analyse_first): Use recursion rather than an explicit stack. (re_compile_fastmap): Can't fail anymore. (re_search_2): Don't check re_compile_fastmap for failure. (PUSH_NUMBER): Renamed from PUSH_FAILURE_COUNT. Now also sets the new value (passed in a new argument). (re_match_2_internal): Use it. Also, use a new var `reg' of type size_t when looping through regs rather than reuse the inappropriate `mcnt'. 2000-10-25 Jim Meyering * lib/obstack.c: Update from libc. 2000-10-24 Kenichi Handa * regex.c (regex_compile): Change the way of handling a range from a char less than 256 to a char not less than 256. 2000-10-24 Andrew Innes * regex.c (IMMEDIATE_QUIT_CHECK): New macro, which does QUIT on NT-Emacs only. (re_match_2_internal): Use IMMEDIATE_QUIT_CHECK instead of QUIT, so that re_search functions only quit when callers expect them to. 2000-10-23 Jim Meyering * lib/hard-locale.c (hard_locale): Revert last change -- it was simply wrong. That set_locale call must not have any side effects. From Paul Eggert. 2000-10-22 Jim Meyering * lib/md5.c (md5_process_block) [OP]: Use `rol', not CYCLIC. [CYCLIC]: Remove now-unused definition. * lib/save-cwd.c (O_DIRECTORY): Define, if needed. (save_cwd) [HAVE_FCHDIR]: Use O_DIRECTORY when opening ".". Suggestion from Ulrich Drepper. 2000-10-21 Jim Meyering * m4/check-decl.m4 (jm_CHECK_DECLS): Also check for memrchr. * m4/prereq.m4 (jm_PREREQ_DIRNAME): New macro. * m4/jm-macros.m4 (AC_REPLACE_FUNCS): Add memrchr. 2000-10-21 Jim Meyering * lib/dirname.c (memrchr): Declare if necessary. (dir_name): Remove the restriction that there be no trailing slashes. Now, this code skips past them, effectively ignoring them. [TEST_DIRNAME] (main): New unit tests. * lib/memrchr.c: New file from GNU libc. Undef __memrchr, too. [!weak_alias]: Define __memrchr to memrchr. Guard weak_alias use with `#ifdef weak_alias'. 2000-10-21 Jim Meyering * lib/dirname.c (dir_name_r): New function, factored out of dir_name. (dir_name): Use dir_name_r. * lib/dirname.h (dir_name_r): Declare it. 2000-10-17 Jim Meyering * lib/quote.h (PARAMS): Define and use. Reported by Akim Demaille. * lib/getopt.c: Update from libc. 2000-10-16 Jim Meyering * lib/hard-locale.c (hard_locale): Use "", not 0 as 2nd arg to setlocale. From Jan Fedak. 2000-10-15 Stefan Monnier * regex.c (WIDE_CHAR_SUPPORT): Define if _LIBC as well. 2000-09-25 Jim Meyering * lib/md5.h (rol): Define (from GnuPG). * lib/sha.c: Give credit (GnuPG) where due. (M): Use rol rather than open-coding it. Add a FIXME comment. 2000-09-21 Jim Meyering * lib/userspec.c (parse_user_spec): Remove debugging printf I'd added. Reported by Michael Stone. 2000-09-20 Jim Meyering * lib/Makefile.am (libfetish_a_SOURCES): Add sha.c. (noinst_HEADERS): Add sha.h. Based on code from Scott G. Miller and from GnuPG. 2000-09-18 Jim Meyering * m4/getloadavg.m4 (AC_FUNC_GETLOADAVG): Restore the initial value of LIBS. Otherwise, everyone ends up linking with -lelf for some configurations. Reported by Mike Stone. 2000-09-15 Jim Meyering * lib/regex.c: Update from libc. 2000-09-10 Jim Meyering * lib/getopt.c (_getopt_internal): Update from glibc. 2000-09-09 Jim Meyering * lib/quotearg.c: Rename ISASCII to IN_CTYPE_DOMAIN, so people don't think it should be used as a general replacement for isascii. * lib/fnmatch.c: Likewise. * lib/mbswidth.c: Likewise * lib/regex.c: Likewise. Don't use atoi. * lib/userspec.c: Include sys/param.h and limits.h. Include xstrtol.h. (CHAR_BIT, TYPE_SIGNED, TYPE_MINIMUM, TYPE_MAXIMUM): Define. (UID_T_MAX, GID_T_MAX, MAXUID, MAXGID): Define. (parse_user_spec): Use xstrtoul, not atoi when converting numeric UID, GID. Check range. 2000-09-06 Jim Meyering * lib/getopt.c (_getopt_internal): Update from glibc. 2000-08-30 Jim Meyering * lib/strftime.c: Merge in changes from GNU libc. 2000-08-26 Jim Meyering * m4/jm-macros.m4: Use jm_FUNC_FPENDING. * m4/fpending.m4: New file. 2000-08-26 Jim Meyering * lib/closeout.c: Include "__fpending.h". (close_stdout_status): Return right away if there's nothing to flush. * lib/Makefile.am (noinst_HEADERS): Add __fpending.h. * lib/__fpending.c: New file. * lib/__fpending.h: New file. 2000-08-20 Jim Meyering * m4/check-decl.m4: Include utmp.h `#if HAVE_UTMP_H', rather than `#if !HAVE_UTMPX_H'. The latter would lose on systems with neither utmp.h nor utmpx.h. Reported by Eli Zaretskii. 2000-08-11 J. David Anglin Improve fileutils installation on systems where running programs (like install) can't be unlinked. * m4/unlink-busy.m4 (jm_FUNC_UNLINK_BUSY_TEXT): New file/macro. * m4/jm-macros.m4: Use jm_FUNC_UNLINK_BUSY_TEXT. 2000-08-07 Paul Eggert Standardize on "memory exhausted" instead of "Memory exhausted" or "virtual memory exhausted". * lib/obstack.c (print_and_abort): Use "memory exhausted", not "virtual memory exhausted". * lib/same.c (same_name): Invoke xalloc_die instead of printing our own message. * lib/userspec.c (parse_user_spec): Likewise. * lib/bumpalloc.h: comment fix * lib/same.c, userspec.c: Include xalloc.h. * lib/xalloc.h (xalloc_msg_memory_exhausted): Now char const[], not char *const and pointing to a constant array. * lib/xmalloc.c (xalloc_msg_memory_exhausted): Likewise. (xrealloc): Comment fix. * lib/userspec.c (parse_user_spec): Don't translate a message until just before returning, to avoid unnecessary translation. 2000-08-07 Jim Meyering * lib/addext.c, argmatch.c, argmatch.h, backupfile.h, bumpalloc.h, chown.c, diacrit.h, dirname.h, dup2.c, exclude.h, fileblocks.c, fnmatch.c, fnmatch.h, fsusage.c, fsusage.h, getdate.h, getgroups.c, gethostname.c, getopt.h, group-member.c, hard-locale.c, hash.h, isdir.c, lchown.c, linebuffer.c, linebuffer.h, long-options.h, malloc.c, md5.c, md5.h, memchr.c, memcmp.c, memcoll.c, memset.c, mktime.c, modechange.h, obstack.h, pathmax.h, realloc.c, rmdir.c, safe-read.c, save-cwd.c, stime.c, stpcpy.c, strcasecmp.c, strcspn.c, strdup.c, stripslash.c, strstr.c, strtod.c, strtol.c, strtoul.c, strtoull.c, strtoumax.c, utime.c, version-etc.h, xalloc.h, xstrdup.c, xstrtoumax.c, yesno.c: Back out Copyright date changes for each file with no change this year. This eases coordination with other programs using the same source code modules. From Paul Eggert. 2000-08-06 Paul Eggert * m4/mbstate_t.m4 (AC_MBSTATE_T): Define mbstate_t to be int, not char, for compatibility with glibc 2.1.3 strftime.c. 2000-08-03 Greg McGary * lib/regex.c (SET_HIGH_BOUND, MOVE_BUFFER_POINTER, ELSE_EXTEND_BUFFER_HIGH_BOUND): New macros. (EXTEND_BUFFER): Use them. 2000-08-01 Jim Meyering * lib/dirname.c (ISSLASH): Define. (BACKSLASH_IS_PATH_SEPARATOR): Define. (dir_name) [BACKSLASH_IS_PATH_SEPARATOR]: Handle the case in which both `\' and `/' may be use as path separators. Based on a patch from Prashant TR. 2000-07-31 Paul Eggert * lib/quotearg.c (quotearg_n_options): Don't make the initial slot vector a constant, since it might get modified. 2000-07-31 Jim Meyering * lib/xmalloc.c: Use `virtual memory exhausted', not `Memory exhausted'. * lib/obstack.c (print_and_abort): Likewise. 2000-07-30 Paul Eggert * lib/quotearg.c (quotearg_n_options): Preallocate a slot 0 buffer, so that the caller can always quote one small component of a "memory exhausted" message in slot 0. From a suggestion by Jim Meyering. 2000-07-30 Jim Meyering * lib/makepath.c (make_path): Quote the other instance, too. * lib/quotearg.c (N_STATIC_SLOTVECS): Define. (STATIC_BUF_SIZE): Define. (quotearg_n_options): Use only statically allocated storage when N < N_STATIC_SLOTVECS and the length of the quoted result is smaller than STATIC_BUF_SIZE. 2000-07-29 Jim Meyering * lib/diacrit.c (diacrit_diac): Use __MSDOS__ in favor of MSDOS. * lib/dirname.c (dir_name): Likewise. * lib/basename.c (base_name): Use ISSLASH rather than comparing against `/'. * lib/dirname.c (dir_name) [MSDOS]: Declare `lim' to be const. (dir_name): Assert that there are no trailing slashes. 2000-07-29 Bruno Haible * lib/mbswidth.h (mbswidth): Add a flags argument. (mbswidth): New declaration. (MBSW_ACCEPT_INVALID, MBSW_ACCEPT_UNPRINTABLE): New macros. * lib/mbswidth.c (mbswidth): Add a flags argument. (mbsnwidth): New function. 2000-07-24 Jim Meyering * lib/mbswidth.c: Remove useless #else. From Bruno Haible. 2000-07-23 Paul Eggert * m4/mbswidth.m4 (jm_PREREQ_MBSWIDTH): Check for wcwidth declaration. 2000-07-23 Paul Eggert * lib/quotearg.c: Streamline by invoking multibyte code only if needed. : Include only if HAVE_MBRTOWC && 1 < MB_LEN_MAX. (MB_CUR_MAX): Redefine to 1 if ! (HAVE_MBRTOWC && 1 < MB_LEN_MAX). (quotearg_buffer_restyled): If a unibyte locale, don't bother to invoke multibyte primitives. 2000-07-23 Paul Eggert * lib/quotearg.c: Include even if ! (HAVE_MBRTOWC && 1 < MB_LEN_MAX), so that mbstate_t is always defined. Do not inspect MB_LEN_MAX, since it's incorrectly defined to be 1 in at least one GCC installation, and this configuration error is likely to be common. Ignoring MB_LEN_MAX hurts performance on hosts that have mbrtowc but have only unibyte locales, but I assume these hosts are rare. 2000-07-23 Paul Eggert * lib/mbswidth.c (_XOPEN_SOURCE): Don't define; this causes problems on Solaris 7. (wcwidth) [!HAVE_DECL_WCWIDTH]: Declare. 2000-07-23 Jim Meyering * m4/check-decl.m4 (jm_CHECK_DECLS): Check for declarations of these, too: getgrgid, getpwuid, getuid. 2000-07-23 Jim Meyering * lib/basename.c (base_name): Add an assertion. 2000-07-23 Bruno Haible * lib/quotearg.c: When the system forces us to redefine mbstate_t, shadow its mbsinit function. 2000-07-17 Bruno Haible * lib/mbswidth.h: New file. * lib/mbswidth.c: New file. * lib/Makefile.am (libfetish_a_SOURCES): Add mbswidth.c. (noinst_HEADERS): Add mbswidth.h. 2000-07-17 Bruno Haible * lib/config.charset: Add support for FreeBSD. Improve support for HP-UX and IRIX 6. 2000-07-16 Bruno Haible * m4/mbswidth.m4: New file. * m4/prereq.m4 (jm_PREREQ): Call jm_PREREQ_MBSWIDTH. 2000-07-15 Jim Meyering * lib/makepath.c: Include quote.h. (make_path): Convert "`%s'" in format strings to "%s", and wrap each corresponding argument in a `quote (...)' call. Give better diagnostics. * lib/Makefile.am (libfetish_a_SOURCES): Add quote.c. (noinst_HEADERS): Add quote.h. * lib/quote.c (quote, quote_n): New file. Two functions taken verbatim from tar's src/misc.c. * lib/quote.h: New file. Prototypes for same. 2000-07-14 Paul Eggert From a suggestion by Bruno Haible. * lib/quotearg.c (mbrtowc): Do not use HAVE_WCHAR_H in the definition. Use defined mbstate_t, not HAVE_MBSTATE_T_OBJECT, to decide whether to define the BeOS workaround macro; this adjusts to the change to AC_MBSTATE_T. 2000-07-14 Jim Meyering * m4/xstrtoumax.m4 (jm_AC_PREREQ_XSTRTOUMAX): Require jm_AC_TYPE_UINTMAX_T. 2000-07-13 Paul Eggert * lib/quotearg.h (enum quoting style): New enum clocale_quoting_style. * lib/quotearg.c (quoting_style_args, quoting_style_vals, quotearg_buffer_restyled): Add support for clocale_quoting_style. Undo previous change to locale_quoting_style behavior, and undo the "{LEFT QUOTATION MARK}" and "{RIGHT QUOTATION MARK}" msgids. 2000-07-10 Paul Eggert From a suggestion by Bruno Haible. * m4/mbstate_t.m4 (AC_MBSTATE_T): Renamed from AC_MBSTATE_T_OBJECT. All uses changed. Change from a two-part test, which defines both HAVE_MBSTATE_T_OBJECT and mbstate_t, to a single-part test that simply defines mbstate_t. * m4/prereq.m4 (jm_PREREQ_QUOTEARG): s/AC_MBSTATE_T_OBJECT/AC_MBSTATE_T/. 2000-07-10 Jim Meyering * m4/strerror_r.m4: Mirror the correction made in autoconf. * m4/gnu-source.m4: Output to confdefs.h directly. Suggestion from Akim Demaille. 2000-07-09 Paul Eggert The old behavior of quoting `like this' doesn't look good with newer, ISO-style fonts. See: http://www.cl.cam.ac.uk/~mgk25/ucs/quotes.html Instead, quote "like this" by default. Let the translator tailor the locale-specific quoting behavior by providing translations for {LEFT QUOTATION MARK} and {RIGHT QUOTATION MARK}. * lib/quotearg.c (N_): New macro. (gettext_default): New function. (quotearg_buffer_restyled): Use gettext_default ("{LEFT QUOTATION MARK}", "\"") for left quote, and gettext_default ("{RIGHT QUOTATION MARK}", "\"") for right quote. 2000-07-09 Jim Meyering * m4/jm-macros.m4 (jm_MACROS): Add a test to see if -lm is required to link seq. If so, set SEQ_LIBM to -lm. From Bruno Haible. * m4/gnu-source.m4 (AC__GNU_SOURCE): New file/macro. * m4/jm-macros.m4 (jm_CHECK_ALL_TYPES): Require it. 2000-07-09 Jim Meyering * lib/Most files: Update copyright dates to include 2000. 2000-07-08 Jim Meyering * lib/xgethostname.c (ENAMETOOLONG): Define to an unlikely value if not defined. (xgethostname): Remove now-unnecessary #ifdef. Move declaration of `err' into loop where it's used. 2000-07-05 Paul Eggert and Bruno Haible * m4/mbstate_t.m4 (AC_MBSTATE_T_OBJECT): Test for mbstate_t only if the test for an object-type mbstate_t fails. This prevents us from mistakenly reporting that mbstate_t is a system object type after we "#define mbstate_t int" to work around its lack. 2000-07-05 Paul Eggert and Bruno Haible * lib/quotearg.c (mbrtowc): Declare returned type, since BeOS doesn't. 2000-07-05 Bruno Haible * m4/strerror_r.m4 (AC_FUNC_STRERROR_R): Pass a reasonably large buffer to strerror_r. Include for use of isalpha. 2000-07-05 Bruno Haible * lib/xgethostname.c (xgethostname): Protect against the SunOS 5.5 bug by allocating a larger buffer. Test the gethostname return value for being >= 0, not == 0, for BeOS. Don't exhaust memory if gethostname returns an error and ENAMETOOLONG isn't defined. 2000-07-05 Bruno Haible * lib/quotearg.c (struct quoting_options): Simplify quote_these_too dimension. 2000-07-04 Jim Meyering * m4/fsusage.m4 (jm_FILE_SYSTEM_USAGE): Use plain old `echo' instead of the deprecated AC_CHECKING. 2000-07-04 Jim Meyering * lib/strndup.c: [!HAVE_DECL_STRNLEN]: Declare strnlen. Reported by Bruno Haible. 2000-07-04 Jim Meyering * lib/quotearg.c: Make inclusion of independent of whether HAVE_MBRTOWC is set. Required at least for irix-5.6, which lacks mbrtowc. 2000-07-03 Paul Eggert * m4/mbstate_t.m4 (AC_MBSTATE_T_OBJECT): Port to autoconf 2.13. Add AC_CHECK_HEADERS(stdlib.h), since we use HAVE_STDLIB_H. 2000-07-03 Paul Eggert and Bruno Haible * lib/quotearg.c (mbrtowc): Assign to *pwc, and return 1 only if result is nonzero. (iswprint): Use ISPRINT when substituting our own mbrtowc. 2000-07-03 Jim Meyering * m4/check-decl.m4 (AC_CHECK_DECLS): Add strnlen. 2000-07-03 Jim Meyering * lib/readutmp.h: [HAVE_UTMPX_H]: Include if HAVE_UTMP_H. This is necessary to get a definition of e.g., UTMP_FILE on HP-UX 10.20. From Bob Proulx. 2000-07-02 Jim Meyering * m4/mbstate_t.m4: Also define mbstate_t, if necessary. * m4/chown.m4: Replace each use of AC_SUBST(LIBOBJS)/LIBOBJS=... with AC_LIBOBJ(function_name). * m4/chown.m4: Likewise. * m4/fnmatch.m4: Likewise. * m4/ftruncate.m4: Likewise. * m4/getgroups.m4: Likewise. * m4/getline.m4: Likewise. * m4/group-member.m4: Likewise. * m4/jm-macros.m4: Likewise. * m4/lstat.m4: Likewise. * m4/malloc.m4: Likewise. * m4/memcmp.m4: Likewise. * m4/nanosleep.m4: Likewise. * m4/putenv.m4: Likewise. * m4/realloc.m4: Likewise. * m4/regex.m4: Likewise. * m4/stat.m4: Likewise. * m4/strftime.m4: Likewise. 2000-07-02 Jim Meyering * lib/quotearg.c (mbstate_t): Don't define here. 2000-07-02 Jim Meyering * lib/nanosleep.c (SIGCONT): Define if not already defined. 2000-07-01 Jim Meyering * m4/uptime.m4: Put double quotes around use of $cross_compiling. 2000-07-01 Jim Meyering * m4/ls-mntd-fs.m4: Remove a `FIXME' comment and fix the associated problem. 2000-07-01 Bruno Haible * m4/ls-mntd-fs.m4 (jm_LIST_MOUNTED_FILESYSTEMS): Rename BeOS specific macro from MOUNTED_NEXT_DEV to MOUNTED_FS_STAT_DEV. 2000-07-01 Bruno Haible * lib/mountlist.c: Use MOUNTED_FS_STAT_DEV instead of MOUNTED_NEXT_DEV, per change in ../m4/ls-mntd-fs.m4. (read_filesystem_list): Ignore symbolic links. 2000-06-29 Jim Meyering * lib/same.c: Include or , as appropriate, for declaration of strcmp. * lib/long-options.c: Include , for declaration of exit. * lib/mountlist.c (fsp_to_string) [HAVE_F_FSTYPENAME_IN_STATFS]: Avoid warning by casting result to `char *' to remove `const'. 2000-06-28 Jim Meyering * m4/mbstate_t.m4: Use stdlib.h, not stdio.h. The latter is not included by quotearg.c, for which we perform this test. From Bruno Haible. 2000-06-27 Bruno Haible * m4/check-decl.m4 (_jm_DECL_HEADERS): Check for utmp.h as well. * m4/prereq.m4 (jm_PREREQ_READUTMP): Likewise. If either or exists, put readutmp.o into LIBOBJS. 2000-06-27 Bruno Haible * lib/Makefile.am (libfetish_a_SOURCES): Remove readutmp.c. 2000-06-26 Paul Eggert savedir now sets errno on failure and invokes xmalloc to get memory. Fix a couple of other minor bugs while we're at it. * lib/savedir.c (): Do not include; there's no need. (NAMLEN): Remove macro. (malloc, realloc): Remove decls. (stpcpy): Likewise. ("xalloc.h"): Include. (NAME_SIZE_DEFAULT): New macro. (savedir): Use xmalloc / xrealloc to allocate memory. Use NAME_SIZE_DEFAULT if name_size is negative or overflows to zero. Skip "" directory entries. Use strlen to calculate directory entry length, since the old method is rarely used these days and isn't worth supporting. Don't use a pointer after freeing it. Check for integer overflow when calculating allocation size. Use memcpy to copy entries, instead of stpcpy. Set errno properly when returning NULL. Check for readdir error. 2000-06-26 Jim Meyering * lib/posixtm.c [HAVE_STDLIB_H]: Include stdlib.h, for decl of abort. 2000-06-25 Jim Meyering * m4/mbstate_t.m4: Include stdio.h before wchar.h to work around Linux header bug when _XOPEN_SOURCE is defined to 500. 2000-06-25 Bruno Haible * lib/unicodeio.c (print_unicode_char): Work around ansi2knr deficiency. 2000-06-25 Bruno Haible * lib/getusershell.c (xmalloc, xrealloc): Remove functions. Include xalloc.h. Don't include . Don't declare malloc, realloc. 2000-06-24 Jim Meyering * m4/strerror_r.m4: Revive this file -- to try out an experimental version of AC_FUNC_STRERROR_R that may work even on BeOS, a system for which strerror does return char*, but which lacks a conveniently accessible declaration of the function. If the compile-test says strerror_r doesn't work, then resort to a `run'-test that works on BeOS and segfaults on DEC Unix. 2000-06-24 Jim Meyering * lib/error.c [!HAVE_DECL_STRERROR_R]: Declare strerror_r. 2000-06-23 Paul Eggert * m4/mbstate_t.m4: New file, defining AC_MBSTATE_T_OBJECT. * m4/prereq.m4 (jm_PREREQ_QUOTEARG): Use it. Add check for iswprint. 2000-06-23 Paul Eggert * lib/quotearg.c: Include after , for Solaris 2.5. (mbrtowc, mbstate_t): Define substitutes if HAVE_MBRTOWC && HAVE_WCHAR_H && !HAVE_MBSTATE_T_OBJECT. (iswprint): Define to 1 if !defined iswprint && !HAVE_ISWPRINT, not if ! (HAVE_MBRTOWC && HAVE_WCHAR_H). 2000-06-23 Jim Meyering * m4/afs.m4: Add missing AC_MSG_RESULT. Reported by Bruno Haible. * m4/fsusage.m4: s/AC_MSG_CHECKING/AC_CHECKING/. Suggestion from Bruno Haible. 2000-06-23 Jim Meyering * lib/getpass.c: New file, from Bruno Haible. Required for BeOS. 2000-06-21 Jim Meyering * m4/jm-macros.m4 (AC_REPLACE_FUNCS): Add getpass. 2000-06-21 Jim Meyering * lib/Makefile.am (libfetish_a_SOURCES): Add getstr.c. (noinst_HEADERS): Add getstr.h. * lib/getline.c (getstr): Move into a separate file. * lib/getstr.c (getstr): New file, extracted from getline.c, with the following changes: new parameter, delim2; both delim[12] parameters have type `int', not `char'. The latter would lose with 8-bit delimiters. * lib/getstr.h: New file. 2000-06-21 Bruno Haible * lib/xgetcwd.c (xgetcwd): If the required pathname length is smaller than 1024, return a memory chunk of least possible size, instead of size PATH_MAX + 2. In the loop, increment the size proportionally. Use free/xmalloc instead of xrealloc to avoid copying for very long paths. 2000-06-21 Bruno Haible * lib/path-concat.c (path_concat): Don't access dir[-1] if dir is the empty string. 2000-06-21 Bruno Haible * lib/canon-host.c (canon_host): Use malloc and memcpy to copy an address, not strdup. Include and don't declare free(). 2000-06-19 Jim Meyering * lib/getloadavg.c [HAVE_NLIST_H] (NLIST_STRUCT): Define. 2000-06-18 Jim Meyering * m4/jm-macros.m4 (AC_REPLACE_FUNCS): Remove mkdir. * m4/link-follow.m4 (jm_AC_FUNC_LINK_FOLLOWS_SYMLINK): Change the `checking whether...' message to be consistent with that of the lstat test. 2000-06-18 Jim Meyering * lib/mkdir.c: Remove file, due mainly to copyright incompatibility. Besides, these days every porting target provides a mkdir function. * lib/strnlen.c: Include memory.h, string.h, and/or strings.h as needed. (this snippet comes from src/system.h). 2000-06-16 Bruno Haible * m4/glibc21.m4 (jm_GLIBC21): Define GLIBC21 for Makefiles, not for C. 2000-06-15 Paul Eggert * lib/human.c (adjust_value): New function. (human_readable_inexact): Apply rounding style even when printing approximate values. 2000-06-14 Paul Eggert * lib/human.c (human_readable_inexact): Allow an input block size that is not a multiple of the output block size, and vice versa. Reported by Piergiorgio Sartor. 2000-06-14 Paul Eggert * lib/getdate.y (get_date): Apply relative times after time zone indicator, not before. Reported by Todd A. Jacobs. 2000-06-13 Jim Meyering * lib/Makefile.am (all-local): Depend on lstat.c and stat.c. * lib/xstat.in [!HAVE_DECL_FREE]: Declare free in lstat.c. 2000-06-12 Paul Eggert * lib/xstat.in: Include in lstat, to declare "free". 2000-06-12 Jim Meyering * m4/getloadavg.m4 (AM_FUNC_GETLOADAVG): Replace with AC_FUNC_GETLOADAVG from autoconf, and tweak the latter to accept an optional argument. * m4/jm-macros.m4: s/AM_FUNC_GETLOADAVG/AC_FUNC_GETLOADAVG/, and supply the optional argument, `lib'. 2000-06-08 Jim Meyering * m4/largefile.m4: Remove file (now that it's part of autoconf). 2000-06-04 Paul Eggert Rewrite largefile configuration so that we don't need to run getconf and don't need AC_CANONICAL_HOST. [I'm leaving the use of AC_CANONICAL_HOST in configure.in -- jmm] * m4/largefile.m4 (AC_SYS_LARGEFILE_FLAGS, AC_SYS_LARGEFILE_SPACE_APPEND): Remove. (AC_SYS_LARGEFILE_TEST_INCLUDES): New macro. (AC_SYS_LARGEFILE_MACRO_VALUE): Change arguments from CODE-TO-SET-DEFAULT to VALUE, INCLUDES, FUNCTION-BODY. All uses changed. Instead of inspecting the output of getconf, try to compile the test program without and with the macro definition. (AC_SYS_LARGEFILE): Do not require AC_CANONICAL_HOST or check for getconf. Instead, check for the needed flags by compiling test programs. 2000-06-04 Paul Eggert * lib/strnlen.c: Include if HAVE_CONFIG_H. 2000-06-04 Jim Meyering * lib/getugroups.c (getugroups): Cast -1 to gid_t, for systems like SunOS 4.1.4 for which gid_t is an unsigned type. 2000-06-03 Jim Meyering * m4/prereq.m4 (jm_PREREQ_HUMAN): Use []-quoted list in AC_CHECK_DECLS, now that autoconf requires that. * m4/jm-glibc-io.m4: Add a kludge to make autoheader emit the required #undefs. E.g., #undef HAVE_DECL_FERROR_UNLOCKED. Use []-quoted list in AC_CHECK_DECLS, now that autoconf requires that. 2000-06-03 Jim Meyering * lib/strnlen.c [!HAVE_DECL_MEMCHR]: Declare memchr. 2000-06-03 Bruno Haible * m4/glibc21.m4: New file. * m4/jm-macros.m4 (jm_MACROS): Call jm_GLIBC21. 2000-06-03 Bruno Haible * lib/Makefile.am (install-exec-local): On systems with glibc-2.1 or newer, don't install charset.alias. * lib/config.charset: Change the Linux/glibc rules so they become empty on glibc-2.1 or newer. 2000-06-02 Jim Meyering * lib/mountlist.c: Back out last change.

(hash_delete): Rewrite to use neither the assignment operator nor the comma operator in an if-expression. 2000-05-15 Paul Eggert * lib/closeout.c: , , , (STDOUT_FILENO): Remove; no longer needed. "quotearg.h": Add include. (file_name): Do not bother to explicitly initialize to NULL; it's less efficient on some hosts. (close_stdout_status): Remove test as to whether stdout was already closed; it breaks for the case "echo x | sort >&-". Quote file name colons. Do not assume that _("write error") lacks format strings. 2000-05-15 Jim Meyering * lib/version-etc.c (version_etc_copyright): Update the copyright string used in all --version output. 2000-05-14 Jim Meyering * lib/closeout.c (close_stdout_set_file_name): New function.

Otherwise, regex.h is included first, then limits.h is included by locale.h by libintl.h. From John David Anglin. 2000-04-25 Jim Meyering * lib/makepath.c (S_IRWXUGO): Define. (make_path): Always perform explicit chmod if MODE specifies any of the `special' permission bits.

Based on a patch from Bruno Haible. 2000-04-17 Jim Meyering Get it right :-) * m4/jm-macros.m4 (jm_CHECK_ALL_TYPES) [_GNU_SOURCE]: Emit the actual #define via AH_VERBATIM. Don't need separate AC_DEFINE. Suggestion from Akim Demaille. 2000-04-17 Jim Meyering * lib/strftime.c (my_strftime) [strftime]: Declare strftime here, since the definition of it to rpl_strftime also defined-away the system's declaration. 2000-04-15 Jim Meyering Use `C' to denote so-called `contiguous' files, the same way that tar does. * lib/filemode.c (S_ISCTG) [!S_ISCTG && S_IFCTG]: Define. (ftypelet): Use S_ISCTG. From Michael Deutschmann. 2000-04-14 Jim Meyering * m4/jm-macros.m4 (jm_CHECK_ALL_TYPES) [_GNU_SOURCE]: Use the one-arg form of AC_DEFINE.

Thanks to a report from Christian Krackowizer. More code moved from ../configure.in into (jm_CHECK_ALL_TYPES). * m4/jm-macros.m4 (_GNU_SOURCE): Define. (AC_SYS_LARGEFILE): Require. (AM_C_PROTOTYPES): Require. 2000-04-08 Jim Meyering * lib/Makefile.am (charset.alias): Use t-$@, not $@-t so the DOS 8.3 names don't conflict.

From Bruno Haible. 2000-04-07 Bruno Haible * lib/unicodeio.c (print_unicode_char): Avoid triggering Solaris iconv bug. Deal with the different error behavior of Irix iconv. 2000-04-05 Paul Eggert * m4/largefile.m4 (AC_SYS_LARGEFILE_FLAGS): Don't use -n32 on IRIX if the installer said otherwise. 2000-04-05 Jim Meyering Portability tweaks required for ultrix4.3. * m4/check-decl.m4 [!HAVE_UTMPX_H] (headers): Include . (jm_CHECK_DECLS): Add getutent to the list of functions. (_jm_DECL_HEADERS): Add utmpx.h. From John David Anglin. * m4/strftime.m4: Back out the 2000-04-02 change. Instead of that change, simply undefine putenv in the test program. 2000-04-05 Jim Meyering Portability tweaks required for ultrix4.3. * lib/readutmp.h [HAVE_UTMPX_H && !HAVE_DECL_GETUTENT]: Declare getutent. * lib/readutmp.c: Include sys/types.h before sys/stat.h. * lib/canon-host.c: Declare strdup. * lib/path-concat.c: Likewise.

Reported by Eli Zaretskii. 2000-04-03 Jim Meyering * m4/gettext.m4: Fix typo in comment. * m4/codeset.m4 (AC_CHECK_HEADERS): Add langinfo.h (moved here from textutils/configure.in). Suggestion from Paul Eggert. (AC_CHECK_FUNCS): Add nl_langinfo. (also from textutils/configure.in) 2000-04-02 Paul Eggert * m4/strftime.m4 (jm_FUNC_GNU_STRFTIME): Set TZ environment variable in the shell rather than using putenv, which isn't portable. This avoids the configure-time inter-test dependency on the potentially-renamed putenv function. 2000-03-30 Paul Eggert * m4/jm-macros.m4 (jm_CHECK_ALL_TYPES): Include before checking struct stat.st_blksize, so that HAVE_STRUCT_STAT_ST_BLKSIZE is defined correctly. 2000-03-29 Paul Eggert * m4/strftime.m4 (_jm_STRFTIME_PREREQS): Check for strftime, since strftime.c uses HAVE_STRFTIME to decide whether to use the underlying strftime. 2000-03-29 Paul Eggert * lib/time/strftime.c (my_strftime): Make sure we call the system strftime, not ourselves, when invoking the underlying strftime. 2000-03-24 Jim Meyering * lib/Makefile.am (EXTRA_DIST): Add ref-add.sed.in and ref-del.sed.in. (charset_alias): Define. (install-exec-local): Factor out common code. (uninstall-local): Split lines longer than 80. (ref-add.sed, ref-del.sed): Remove rules...

(print_unicode_char): Pass the Unicode character to iconv in UTF-8 format instead of in UCS-4 with platform dependent endianness. 2000-03-10 Jim Meyering * m4/lib-check.m4: Look for getspnam in -lgen, too. From Marco Franzen. 2000-03-07 Paul Eggert * lib/savedir.c (savedir): Work even if directory size is negative; this can happen with some screwy NFS configurations. 2000-03-06 Jim Meyering * lib/localcharset.c (get_charset_aliases): Don't try to free file_name if it's NULL (because we ran out of memory). From Bruno Haible. 2000-03-05 Jim Meyering * lib/localcharset.c ("path-concat.h"): Include.

Guard declaration of strtoull also with `&& HAVE_UNSIGNED_LONG_LONG'. * lib/backupfile.c: Guard inclusion of stdlib.h with `#if HAVE_STDLIB_H', not `#if STDC_HEADERS'. Declare malloc if needed. * lib/backupfile.c: Use `#if !HAVE_DECL...' instead of `#ifndef HAVE_DECL..' now that autoconf always defines the HAVE_DECL_ symbols. * lib/human.c: Likewise. * lib/same.c: Likewise. * lib/strtoumax.c: Likewise. * lib/backupfile.c: Arrange for cpp to fail if the configure-time declaration check was not run. * lib/hash.c: Likewise. * lib/human.c: Likewise. * lib/same.c: Likewise. * lib/strtoumax.c: Likewise. * lib/userspec.c (parse_user_spec): If there is no `:' but there is a `.', then first look up the entire `.'-containing string as a login name. 2000-02-23 Jim Meyering * m4/check-decl.m4: Now that we have the new AC_CHECK_DECLS, use it in place of my hack. 2000-02-18 Paul Eggert * lib/getdate.y: Handle two-digit years with leading zeros correctly. (textint): New typedef. (parser_control): Member year changed from int to textint. All uses changed. (YYSTYPE): Removed; replaced by %union with int and textint members. (tDAY, tDAY_UNIT, tDAYZONE, tHOUR_UNIT, tID, tLOCAL_ZONE, tMERIDIAN, tMINUTE_UNIT, tMONTH, tMONTH_UNIT tSEC_UNIT, tSNUMBER, tUNUMBER, tYEAR_UNIT, tZONE, o_merid): Now of type . (tSNUMBER, tUNUMBER): Now of type . (date, number, to_year): Use width of number in digits, not its value, to determine whether it's a 2-digit year, or a 2-digit time. (yylex): Store number of digits of numeric tokens. Reported by John Kendall. (parser_control): Changed from struct parser_control to typedef (for consistency). All uses changed. (tID): Removed; not used. (yylex): Return '?' for unknown identifiers, rather than (unused) tID. 2000-02-14 Paul Eggert * lib/getpagesize.h (getpagesize): Port to VMS for Alpha; adapted from changes to grep getpagesize.h by Martin P.J.

Remove explicit use of AC_HEADER_TIME. It is required by jm_CHECK_TYPE_STRUCT_TIMESPEC. Using AC_HEADER_TIME and `AC_REQUIRE'ing jm_CHECK_TYPE_STRUCT_TIMESPEC provoked a but in autoconf whereby the expansion of the latter ended up preceding the expansion of its prerequisite, AC_HEADER_TIME. Reported by Volker Borchert. 2000-02-03 Jim Meyering * m4/prereq.m4 (jm_PREREQ_READUTMP): Check for utmpxname. 2000-02-03 Jim Meyering * lib/readutmp.c (read_utmp): Guard with `#ifdef UTMP_NAME_FUNCTION', rather than with `#if HAVE_UTMPNAME'. 2000-02-02 Jim Meyering * m4/prereq.m4 (jm_PREREQ_ADDEXT): Fix typo that resulted in no definition of HAVE_PATHCONF: s/AC_CHECK_FUNC/AC_CHECK_FUNCS/.

From Andreas Schwab. 2000-01-31 Jim Meyering * m4/check-decl.m4 (jm_CHECK_DECLS): Add nanosleep to the list of functions. Add the time.h and sys/time.h headers along with the AC_REQUIRE'ment of AC_HEADER_TIME. 2000-01-31 Jim Meyering * lib/nanosleep.h (nanosleep): Guard declaration with `#if ! HAVE_DECL_NANOSLEEP'. Without this, OFS gets a redeclaration error for rpl_nanosleep, due to the declaration in that vendor's sys/timers.h. Reported by Christian Krackowizer. * lib/quotearg.c (ISASCII): Add #undef and move definition to follow inclusion of wctype.h to work around Solaris 2.6 namespace pollution. (ISPRINT): Likewise.

Check for ut_user and ut_name members in both struct utmpx and struct utmp. 2000-01-30 Jim Meyering * lib/readutmp.c (extract_trimmed_name): Use UT_USER instead of hard-coding uses of ->ut_name. The latter doesn't work with new Linux header files where only utmpx.ut_user is declared. * lib/readutmp.h (UT_USER): Define. 2000-01-29 Jim Meyering * m4/lib-check.m4: New file containing library-related checks from fileutils and sh-utils (textutils had none). 2000-01-28 Jim Meyering * m4/perl.m4: Change format of warning message to look more like that from the missing script. Suggestion from François Pinard. 2000-01-25 Jim Meyering * m4/timespec.m4: Require AC_HEADER_TIME, and include sys/time.h as well as time.h in the compile check. * m4/nanosleep.m4: Require AC_HEADER_TIME rather than simply using it.

Extracted from fileutils/configure.in. s/space/ac_fsusage_space/. (jm_FILE_SYSTEM_USAGE): Take two parameters. * m4/ftruncate.m4: New file (derived from part of fileutils/configure.in). * m4/jm-macros.m4 (jm_FUNC_FTRUNCATE): AC_REQUIRE it. (jm_CHECK_ALL_TYPES): Require AC_HEADER_MAJOR and AC_HEADER_DIRENT. * m4/jm-macros.m4 (OPTIONAL_BIN_PROGS, OPTIONAL_BIN_ZCRIPTS, MAN): AC_SUBST these here, rather than just in sh-util/configure.in, so that the now-shared-by-fileutils-and-textutils lib/Makefile.am are all the same. (AM_FUNC_OBSTACK): Add (from fileutils/configure.in). (AC_CHECK_FUNCS): Merge all checks from fileutils, textutils, sh-utils. (AM_FUNC_STRTOD): Added (from textutils', sh-utils' configure.in). (AC_SUBST(POW_LIBM)): Likewise.

(AC_CHECK_HEADERS): Likewise for textutils. Merge the three lists of headers. * m4/prereq.m4 (jm_PREREQ_ADDEXT): New macro. Parts moved here from fileutils' configure.in. * m4/decl.m4: Remove kludgy `test -z $ac_...AC_CHECK_HEADERS(...)' code. Moved tests into their own function (_jm_DECL_HEADERS) in check-decl.m4. * m4/check-decl.m4: Use #if rather than #ifdef. Add HAVE_DECL_STRTOUL and HAVE_DECL_STRTOULL. (jm_CHECK_DECLARATIONS): Add strtoul strtoull. (_jm_DECL_HEADERS): Define new function. (jm_CHECK_DECLARATIONS): Require it. 2000-01-22 Jim Meyering * lib/strtoumax.c: [! HAVE_DECL_STRTOUL]: Declare strtoul. [! HAVE_DECL_STRTOULL]: Declare strtoull. Required for some AIX systems. Reported by Christian Krackowizer.

(strverscmp): Use ISDIGIT, not isdigit. 2000-01-19 Jim Meyering * m4/nanosleep.m4 (jm_FUNC_NANOSLEEP): Include , too. Use AC_HEADER_TIME. Volker Borchert reported that OpenBSD-2.3/sparc defines `struct timespec' in * m4/c-bs-a.m4: Remove uses of changequote altogether. Thanks to Akim for explaining. 2000-01-17 Paul Eggert * lib/nanosleep.c (nanosleep): Don't use SA_INTERRUPT to decide whether to call sigaction, as POSIX.1 doesn't require SA_INTERRUPT and some systems (e.g. Solaris 7) don't define it.
