* timespec_getres: new modulePaul Eggert2021-12-282-1/+21
| | | | | | | | | | | * lib/time.in.h (timespec_getres): New decl. * lib/timespec_getres.c, m4/timespec_getres.m4: * modules/timespec_getres, modules/timespec_getres-tests: * tests/test-timespec_getres.c: New files. * m4/time_h.m4 (gl_TIME_H_REQUIRE_DEFAULTS, gl_TIME_H_DEFAULTS): * modules/time (time.h): Support timespec_getres.
* gettime-res: new modulePaul Eggert2021-12-282-4/+13
| | | | | | | * lib/gettime-res.c, modules/gettime-res: New files. * lib/timespec.h (gettime_res): New decl. * m4/clock_time.m4 (gl_CLOCK_TIME): Also check for clock_getres. * m4/gettime.m4 (gl_GETTIME_RES): New macro.
* gettime: port better to non-POSIX C2xPaul Eggert2021-12-281-2/+2
| | | | | | | | | C2x requires a function timespec_get; prefer that to gettimeofday, since it has better resolution. * lib/gettime.c (gettime): Prefer timespec_get to gettimeofday. * m4/gettime.m4 (gl_GETTIME): Check for timespec_get. Omit a check for gettimeofday; not needed because the gettime module depends on the gettimeofday module.
* perl: let caller see whether perl was foundPaul Eggert2021-12-281-9/+16
| | | | | | | Problem reported for coreutils by Serge Belyshev (Bug#52844). * m4/perl.m4 (gl_PERL): Use AC_CACHE_CHECK, so that an invoker of gl_PERL can later inspect gl_cv_prog_perl to see whether perl was found.
* libtextstyle-optional: Fix generation of textstyle.h (regr. 2021-12-15).Bruno Haible2021-12-181-1/+8
| | | | | * m4/libtextstyle-optional.m4 (gl_LIBTEXTSTYLE_OPTIONAL): Invoke gl_CONDITIONAL_HEADER.
* automake-subdir support: Support the libunistring modules.Bruno Haible2021-12-151-2/+6
| | | | | * m4/libunistring-base.m4 (gl_LIBUNISTRING_LIBHEADER): Use the value of the gl_source_base_prefix variable.
* Accommodate non-recursive Automake in a less hacky way.Bruno Haible2021-12-152-3/+12
| | | | | | | | | | | | | | | | | | | | | * gnulib-tool: New option --automake-subdir. (automake_subdir): New variable. (func_emit_initmacro_end): Add a second argument. Use it to prefix each object file name in *_LIBOBJS and *_LTLIBOBJS. (func_emit_shellvars_init): New function. (func_import): Add support for --automake-subdir. Invoke prefix-gnulib-mk. Update calls to func_emit_initmacro_end. Call func_emit_shellvars_init. (func_create_testdir): Update calls to func_emit_initmacro_end.

(contents_of_file): Renamed from contents. (contents_of_stdin): New function. (process): Inline and remove function. * doc/gnulib-tool.texi (Non-recursive make): New section.
* Move .h file names out of the *.m4 files.Bruno Haible2021-12-1534-184/+147

Also mention that we use it on files only. * m4/gl-openssl.m4 (gl_CRYPTO_CHECK): Use manual line breaking, not the line-filling style of AS_HELP_STRING. Show that --with-openssl takes an optional argument. List the hash functions for which we use the OpenSSL library. Don't mention --with-linux-crypto if the af_alg module is not in use. Mention that --with-linux-crypto applies only to the Linux kernel. Mention that it gets used only when available. Mention that it takes precedence only for files. In the error or warning, mention the pre-built package name that people can install.
* string, wchar: Don't require undefined m4 macros (regr. today).Bruno Haible2021-09-192-4/+4
| | | | | | | | | Reported by Colin Watson <cjwatson@debian.org> in <https://lists.gnu.org/archive/html/bug-gnulib/2021-09/msg00078.html>. * m4/string_h.m4 (gl_STRING_H_REQUIRE_DEFAULTS): Don't use m4_require directly. Instead, invoke gl_STDLIB_H_REQUIRE_DEFAULTS. * m4/wchar_h.m4 (gl_WCHAR_H_REQUIRE_DEFAULTS): Likewise.
* string, wchar: Don't cause link errors for rpl_free (regr. 2021-09-07).Bruno Haible2021-09-182-2/+6
| | | | | | | | | | * lib/string.in.h (free, rpl_free): Consider GNULIB_FREE_POSIX variable. * lib/wchar.in.h (free, rpl_free): Likewise. * m4/string_h.m4 (gl_STRING_H_REQUIRE_DEFAULTS): Require module indicator variable initializations from the stdlib module. * m4/wchar_h.m4 (gl_WCHAR_H_REQUIRE_DEFAULTS): Likewise. * modules/string (Makefile.am): Substitute GNULIB_FREE_POSIX in string.h. * modules/wchar (Makefile.am): Substitute GNULIB_FREE_POSIX in wchar.h.
* threadlib: Avoid crashes in thread-related functions on Cygwin 3.2.0.Bruno Haible2021-09-171-26/+36
| | | | | | | | Reported by Brian Inglis via Akim Demaille in <https://lists.gnu.org/archive/html/bug-gnulib/2021-09/msg00063.html>. * m4/threadlib.m4 (gl_WEAK_SYMBOLS): Force a "guessing no" result on Cygwin.

* extern-inline: Fix syntax error on macOS with GCC 11 (regr. 2021-08-22).Bruno Haible2021-09-131-2/+2
| | | | | | | | Reported by Akim Demaille in <https://lists.gnu.org/archive/html/bug-gnulib/2021-09/msg00052.html>. * m4/extern-inline.m4 (_GL_INLINE, _GL_EXTERN_INLINE): Put _GL_UNUSED before, not after, 'static'.
* strerror_r-posix: port even better to AndroidPaul Eggert2021-09-082-2/+7
| | | | | | | | | | | | | | | | * lib/strerror_r.c: Use STRERROR_R_CHAR_P to decide whether the system strerror_r returns char *, and HAVE_DECL_STRERROR_R to decide whether it either does that or returns an integer. 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 AndroidPaul Eggert2021-09-081-4/+6
| | | | | | | | | | | * 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 reported by Lucy Phipps in: https://lists.gnu.org/r/bug-gnulib/2021-09/msg00026.html
* string, wchar: avoid some namespace pollutionPaul Eggert2021-09-071-1/+1
| | | | | | | | | | | * lib/string.in.h, lib/wchar.in.h: (free): Declare by hand instead of including stdlib.h. This avoids some namespace pollution. It should also avoid some nested-include problems described by Lucy Phipps in: https://lists.gnu.org/r/bug-gnulib/2021-09/msg00018.html * modules/string, modules/wchar: (Depends-on): Add stdlib, so that REPLACE_FREE has the right value. (Makefile.am): Replace @REPLACE_FREE@ when creating the include file.

* manywarnings: enable some malloc warningsPaul Eggert2021-08-021-9/+3
| | | | | | | | * m4/manywarnings.m4 (gl_MANYWARN_ALL_GCC): Stop adding -Wno-analyzer-double-free, -Wno-analyzer-null-dereference, and -Wno-analyzer-use-after-free, as these false alarms don’t seem to be as much of an issue now that we’ve pacified a couple of individual modules and GCC has some bug fixes.

* year2038: port to unusual time_t platformsPaul Eggert2021-08-021-25/+36
| | | | | | | | | | | * m4/year2038.m4 (gl_YEAR2038_TEST_INCLUDES): Check that time_t can go to 2**32 - 1, not to 2**63 - 1, as the former is enough to be year 2038 safe. Unsigned 32-bit time_t (AmigaOS) and signed 40-bit time_t (Unisys ClearPath) have occurred in the wild, and even if Gnulib code is rarely or never ported to them there’s no need to exclude them merely because of year 2038 issues. (gl_YEAR2038_BODY): Adjust messages to match. Use 2**32 - 1, not 2**32, as the test timestamp, to allow unsigned 32-bit time_t.
* xalloc: no attribute (malloc (free)) on inlinePaul Eggert2021-08-011-1/+2
| | | | | | | | | | | | | | | | The GCC manual says you can’t use __attribute__ ((__malloc__ (free, 1))) on inline functions. 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). Anyway, the GCC manual says it shouldn’t work at all, so don’t use it. * lib/xalloc.h (xnmalloc, xcharalloc): No longer inline. * lib/xmalloc.c (xcharalloc, xnmalloc): Move function bodies here. * m4/gnulib-common.m4 (_GL_ATTRIBUTE_DEALLOC) (_GL_ATTRIBUTE_DEALLOC_FREE): Document that these cannot be used on inline functions, as per the GCC 11.2.1 manual.

* gnulib-common: update for gcc -Wmismatched-deallocPaul Eggert2021-07-311-0/+12
| | | | | | * m4/gnulib-common.m4 (gl_COMMON_BODY): Define the macros _GL_ATTRIBUTE_DEALLOC and _GL_ATTRIBUTE_DEALLOC_FREE. These can be useful with gcc -Wmismatched-dealloc.
* gnulib-common: update for C2x 2020-12-11 draftPaul Eggert2021-07-311-9/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Use blessed-by-draft-standard way to test for [[__deprecated__]] etc.; this is supported by GCC 11 and the fallback code should work fine with GCC 10 and earlier, clang, etc. * NEWS, doc/attribute.texi: Mention that DEPRECATED etc. must now come first. * lib/fflush.c, lib/unistr.in.h: Do not include unused-parameter.h. All uses of _GL_UNUSED_PARAMETER (after parameters) replaced by _GL_ATTRIBUTE_MAYBE_UNUSED (before parameters). Although perhaps we need a shorter name for _GL_ATTRIBUTE_MAYBE_UNUSED, that should probably be in gnulib-common.m4, due to the ubiquity of this issue. And perhaps the snippet/unused-parameter module should be marked obsolete since it's no longer compatible with its old use. * m4/gnulib-common.m4 (gl_COMMON_BODY): Define the macro _GL_HAS_C_ATTRIBUTE, and use it instead of __STDC_VERSION__ in deciding whether to use C2x attributes like [[__deprecated__]]. (_GL_ATTRIBUTE_MAYBE_UNUSED): Fall back on _GL_ATTRIBUTE_UNUSED. (_GL_ATTRIBUTE_UNUSED): New macro, for labels where C2x [[maybe_unused]] do not work. (_GL_UNUSED, _GL_UNUSED_LABEL): Use it. * modules/fflush, modules/unistr/base (Depends-on): Remove snippet/unused-parameter. * modules/fflush (selinux/selinux.h, selinux/context.h) (selinux/label.h): Do not use $(UNUSED_PARAMETER). Remove useless chmod a-x.
* limits-h: add BOOL_MAX, BOOL_WIDTHPaul Eggert2021-07-311-1/+2
| | | | | | | * doc/posix-headers/limits.texi (limits.h): Document them. * lib/limits.in.h: Also define CHAR_WIDTH etc. if C2x. (BOOL_MAX, BOOL_WIDTH): New macros, from C2x. * m4/limits-h.m4 (gl_LIMITS_H): Also check BOOL_WIDTH.

* regex: modernize to newer regex bugsetPaul Eggert2021-07-141-2/+38
| | | | | | | | | | | Problem reported by Hiroo Hayashi in: https://lists.gnu.org/r/bug-gnulib/2021-07/msg00024.html * m4/regex.m4 (gl_REGEX): Allow newer glibc behavior for ()0|\1, behavior where the regex compiles but does not match. Test for glibc bug 11053. * tests/test-regex.c (bug_regex11, main): Add casts needed for printf portability. (main): Allow newer glibc behavior for ()0|\1.
* regex: fix shell quoting problem in configurationPaul Eggert2021-07-141-3/+3
| | | | | | * m4/regex.m4 (gl_REGEX): Fix quoting problems. These C programs are put into unquoted here-documents, so $ and \ need to be quoted.
* year2038: Add --disable-year2038 optionPaul Eggert2021-07-062-10/+15
| | | | | | | | | | | Also, document this stuff better. Suggested by Bruno Haible in: https://lists.gnu.org/r/bug-gnulib/2021-07/msg00011.html * doc/year2038.texi: Document --disable-year2038. * m4/year2038.m4 (gl_YEAR2038_BODY): Support ‘./configure --disable-year2038’ to disable 64-bit time_t when that is not the default. 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.
* year2038: support glibc 2.34 _TIME_BITS=64Paul Eggert2021-07-012-26/+65
| | | | | | | | | | | | | | | | | | | | | | | | | 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.
