| | | | | | | | | | | | | | * 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.

* lchmod: port back to AIX 7.2Paul Eggert2022-06-191-2/+1
| | | | | | | | | | | 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: port better to MS-Windows etc.Paul Eggert2022-06-122-6/+5
| | | | | | | | | | | | | | | | | | | | | | | | | 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.
* termcap: Fix link error when no suitable library is found.Bruno Haible2022-05-141-1/+6
| | | | | * m4/termcap.m4 (gl_TERMCAP_BODY): If no suitable library is found, set LIBTERMCAP and LTLIBTERMCAP to empty.
* manywarnings: update C warnings for GCC 12Paul Eggert2022-05-121-0/+2
| | | | | | | | | 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.
* glob: improve config and test cleanupPaul Eggert2022-04-281-3/+3
| | | | | | | | | | 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].
* Port _GL_HAS_C_ATTRIBUTE to pedantic gcc -std=c99Paul Eggert2022-04-191-1/+5

* sigsegv: Fix compilation error on arceb CPUs.Bruno Haible2022-04-161-2/+2
| | | | | | | | Reported by Fabrice Fontaine <fontaine.fabrice@gmail.com> in <https://lists.gnu.org/archive/html/bug-gnulib/2022-04/msg00028.html>. * m4/stack-direction.m4 (SV_STACK_DIRECTION): Treat the 'arc' variants like 'arc'.

* Port __has_attribute to Apple’s Clang renumberingPaul Eggert2022-02-251-1/+3
| | | | | | | | | 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 pselectPaul Eggert2022-02-251-23/+1
| | | | | | | | | | | | | | | | | | | | | | | | 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.
* mktime: improve heuristic for ca-1986 Indiana DSTPaul Eggert2022-02-191-4/+25
| | | | | | | | | | | | | | | | Problem reported by Mark Krenz <https://bugs.gnu.org/48085>. * 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.

* extern-inline: improve macOS portPaul Eggert2022-01-171-2/+17
| | | | | | | | | | * 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

* copy-file-range: work around Linux kernel bugPaul Eggert2022-01-142-1/+25
| | | | | | | | | | | | | | | | This workaround is adapted from Coreutils. * lib/copy-file-range.c [__linux__ && HAVE_COPY_FILE_RANGE]: Include <sys/utsname.h>. (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.
