* lib/sys_stat.in.h: Invoke _GL_INLINE_HEADER_BEGIN,
_GL_INLINE_HEADER_END. Include <errno.h>, <unistd.h>.
(_GL_ISSYMLINK_INLINE, _GL_ISSYMLINKAT_INLINE): New macros.
(issymlink, issymlinkat): New declarations.
* lib/unistd.in.h: Do the #include <fcntl.h>, when needed for O_CLOEXEC,
at the end of the file. So that when <fcntl.h> includes <sys/stat.h>,
the declarations of readlink() and readlinkat() on native Windows are
already present.
* lib/issymlink.c: New file.
* lib/issymlinkat.c: New file.
* m4/sys_stat_h.m4 (gl_SYS_STAT_H_REQUIRE_DEFAULTS): Initialize
GNULIB_ISSYMLINK, GNULIB_ISSYMLINKAT.
* modules/sys_stat-h (Depends-on): Add extern-inline.
(Makefile.am): Substitute GNULIB_ISSYMLINK, GNULIB_ISSYMLINKAT.
* modules/issymlink: New file.
* modules/issymlinkat: New file.
To test for a symlink, use readlink, not lstat+S_ISLNK,
when the lstat is used only for the symlink test.
This avoids EOVERFLOW issues.
* lib/lchown.c (rpl_lchown) [CHOWN_CHANGE_TIME_BUG]:
* lib/rename.c (rpl_rename):
[!(_WIN32 && !__CYGWIN__) && (RENAME_TRAILING_SLASH_SOURCE_BUG
|| RENAME_DEST_EXISTS_BUG || RENAME_HARD_LINK_BUG)]:
* lib/renameatu.c (renameatu):
[HAVE_RENAMEAT && RENAME_TRAILING_SLASH_SOURCE_BUG]:
* lib/unlink.c (rpl_unlink):
* lib/unlinkat.c (rpl_unlinkat):
* lib/utimens.c (lutimens) [!HAVE_LUTIMENS]:
Prefer readlink to lstat+S_ISLNK.
* modules/lchown, modules/rename, modules/unlink, modules/utimens:
(Depends-on): Add readlink.
* modules/unlinkat (Depends-on): Add fstatat, readlinkat.
Problem reported by Leah Neukirchen <https://bugs.gnu.org/79139>.
* lib/copy-file-range.c: Include sys-limits.h.
(copy_file_range) [glibc 2.42 and earlier]:
Copy at most SYS_BUFSIZE_MAX bytes.
* m4/copy-file-range.m4 (gl_FUNC_COPY_FILE_RANGE):
Replace on glibc platforms, as well as on Linux platforms.
* modules/copy-file-range (Files): Add lib/sys-limits.h.
* lib/copy-file-range.c [__linux__ && HAVE_COPY_FILE_RANGE]:
Include <linux/version.h>. Include <sys/utsname.h>
only for kernel 5.2 and earlier.
(CHECK_LINUX_KERNEL_VERSION): New macro.
(copy_file_range) [__linux__ && HAVE_COPY_FILE_RANGE]:
Call utsname only when built for kernel 5.2 and earlier.
(copy_file_range) [!__linux__ && HAVE_COPY_FILE_RANGE]:
Use underlying copy_file_range. This doesn’t change
behavior since the code is not compiled in this case,
but it makes the code a bit cleaner.
* modules/copy-file-range (Depends-on): Add bool.
* lib/stackvma.c: On Linux, include <sys/ioctl.h>, <linux/fs.h>.
(vma_iterate_procmap_query): New function.
(vma_iterate): Try vma_iterate_procmap_query first.
* lib/vma-iter.c: On Linux, include <sys/ioctl.h>, <linux/fs.h>.
(vma_iterate_procmap_query): New function.
(vma_iterate): Try vma_iterate_procmap_query first.
Suggested by Collin Funk.
* modules/nstrftime-limited: New file, based on modules/nstrftime.
* modules/nstrftime (Depends-on): Add nstrftime-limited.
Add localename-unsafe. Remove localename-unsafe-limited.
(configure.ac): Invoke gl_MODULE_INDICATOR.
(Makefile.am): Don't add nstrftime.c to lib_SOURCES; this would conflict
with modules/nstrftime-limited.
(Link): Add $(LIBTHREAD).
* lib/strftime.c (SUPPORT_NON_GREG_CALENDARS_IN_STRFTIME): Don't force
to false if GNULIB_NSTRFTIME is defined.
* modules/nstrftime-tests (Makefile.am): Link test-nstrftime,
test-nstrftime-?? with $(LIBTHREAD).
* lib/git-merge-changelog.c: Suggest to pass %Y as 4th parameter.
Include <errno.h>, spawn-pipe.h, wait-process.h, xvasprintf.h,
c-ctype.h.
(_): New macro.
(execute_and_read_line): New function, from lib/javacomp.c.
(is_all_hex_digits): New function.
(long_options): Moved into 'main'.
(usage): Document the --debug option.
(main): Accept a --debug option and turn on debugging at runtime instead
of compile-time. Accept an optional other_conflict_label parameter.
Improve 'downstream' determination using two heuristics.
* modules/git-merge-changelog (Depends-on): Add spawn-pipe,
wait-process, xvasprintf, c-ctype.
This is in response to the GCC developers;
see <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=120993>.
* lib/float.c (gl_LDBL_MAX): Remove the implementation for PowerPC,
as it should no longer be needed.
* lib/float.in.h (LDBL_MIN_EXP, LDBL_MIN_10_EXP, LDBL_MIN)
(LDBL_MAX, LDBL_EPSILON, LDBL_NORM_MAX): On PowerPC with IBM long
double, simplify by using the GCC 15 values unconditionally.
These are the correct values according to the GCC developers
and there seems little point to disagreeing with current GCC
about obsolescent arithmetic that is so problematic in practice.
* tests/test-float-h.c (test_long_double): Relax tests of LDBL_MAX
when !LDBL_IS_IEC_60559, as the tests would now fail on PowerPC and
they were not portable in that case anyway.
Reported by Collin Funk in
<https://lists.gnu.org/archive/html/bug-gnulib/2025-07/msg00170.html>.
* m4/thrd.m4 (gl_FUNC_THRD_JOIN): Define BROKEN_THRD_START_T or
BROKEN_THRD_JOIN. Don't define BROKEN_THRD_START_T_OR_JOIN.
* lib/thrd.c (thrd_main_func): Define with the right return type,
depending on BROKEN_THRD_START_T.
* lib/mkdir-p.c (make_dir_parents): If mkdir fails with ENOENT or
ENOTDIR, do not attempt anything else since the file does not exist.
Treat ENOENT and ENOTDIR consistently later, too.
Problem reported by Lauri Tirkkonen <https://bugs.gnu.org/79072>.
* lib/mkdir-p.c (make_dir_parents):
If savewd_chdir fails due to anything other than EACCES, do
not attempt to preserve permissions; instead, fail with mkdir’s
errno if nonzero, and with savewd_chdir’s errno otherwise.
