* admin/merge-gnulib (GNULIB_MODULES): Add memeq, streq and remove
stringeq, to adjust to a module splitup in Gnulib.
* lib/memeq.c, lib/streq.c, lib/strnul.c, m4/memeq.m4, m4/streq.m4:
New files.
* lib/string.c, m4/stringeq.m4: Remove.
* admin/merge-gnulib (GNULIB_MODULES): Add crypto/sha3-buffer.
* lib/sha3.c: New file, imported by running admin/merge-gnulib.
* lib/sha3.h: Likewise.
* m4/sha3.m4: Likewise.
* lib/gnulib.mk.in: Updated by admin/merge-gnulib.
* m4/gnulib-comp.m4: Likewise.
* src/fns.c: Include sha3.h
(Fsecure_hash_algorithms): Add Qsha3_224, Qsha3_256, Qsha3_384, and
Qsha3_512.
(secure_hash): Likewise.
(Fsecure_hash): List the SHA-3 algorithms in the docstring.
(syms_of_fns): Define Qsha3_224, Qsha3_256, Qsha3_384, and Qsha3_512.
* test/lisp/net/gnutls-tests.el (gnutls-tests-internal-macs-upcased):
Filter out the new SHA-3 algorithms since they are currently not
implemented in gnutls.
* test/src/fns-tests.el (test-secure-hash): Add test cases for the new
algorithms.
* doc/lispref/text.texi (Checksum/Hash): List the SHA-3 algorithms.
Mention that they are considered secure.
* etc/NEWS: Mention the new feature.
Uses of <vla.h>’s macro VLA_ELEMS were removed some time ago.
* admin/merge-gnulib (GNULIB_MODULES): Remove vla.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* lib/vla.h: Remove.
* src/fns.c, src/lread.c: Do not include <vla.h>.
Remove Gnulib sources no longer needed or used.
admin/merge-gnulib is typically not smart enough to do that.
* configure.ac: Do not call gl_EEMALLOC, as it is no longer
supplied or needed.
* lib/explicit_bzero.c, lib/malloc/scratch_buffer_dupfree.c:
* lib/xalloc-oversized.h, m4/eealloc.m4, m4/explicit_bzero.m4:
* m4/st_dm_mode.m4, m4/year2038.m4:
Remove.
* admin/merge-gnulib (AVOIDED_MODULES): Add strncpy, as Emacs is not
likely to exercise the FreeBSD 15 strncpy bug that this module fixes.
* lib/issymlinkat.h: New file, taken from Gnulib.
This merges in changes that were made to Autoconf master
in April 2024. It causes ‘configure’ to prefer the C compiler to
enable C23 features if possible; otherwise, ‘configure’
behaves as before, using C11 if available and C99 if not.
* admin/merge-gnulib (GNULIB_MODULES): Add std-gnu23.
(AVOIDED_MODULES): Add (i.e., start avoiding) std-gnu11.
* m4/std-gnu11.m4: Remove.
* m4/std-gnu23.m4: Add.
See https://lists.gnu.org/archive/html/emacs-devel/2025-11/msg00145.html
for the related discussions.
* nt/mingw-cfg.site (ac_cv_func_acl_entries): Set to "yes" to
disable compilation of lib/acl_entries.c on MinGW.
* lib/acl_entries.c (acl_entries): Revert last change, as it is no
longer needed.
* lib/acl_entries.c (acl_entries): Make it no-op for MinGW, as it
was before. Without this, acl_entries doesn't compile on MinGW.
* nt/gnulib-cfg.mk (OMIT_GNULIB_MODULE_issymlink)
(OMIT_GNULIB_MODULE_issymlinkat): Disable these Gnulib modules.
* admin/merge-gnulib (GNULIB_MODULES): Add stringeq.
With current Gnulib it is already present as in indirect dependency;
listing it here because Emacs now depends on it directly.
* lib-src/ebrowse.c, lib-src/etags.c:
(streq): Remove, as Gnulib defines this now.
* lib/fseterr.c, lib/fseterr.h, lib/issymlink.c, lib/issymlink.h:
* lib/issymlinkat.c, lib/stdio-consolesafe.c, lib/string.c:
* m4/fseterr.m4, m4/gettext_h.m4, m4/stringeq.m4:
New files from Gnulib.
* src/conf_post.h (tzfree) [__ANDROID_API__ >= 35]: Remove.
The following changes were made by hand,
so that admin/merge-gnulib could succeed
instead of failing because the diff didn’t match.
* admin/gnulib-patches/lib/getloadavg.c.diff:
Remove, as it is no longer needed now that recent
Gnulib has been merged.
* admin/merge-gnulib (GNULIB_TOOL_FLAGS):
Remove the --local-dir="$src"admin/gnulib-patches option,
as it is no longer needed either.
* admin/gnulib-patches/lib/getloadavg.c.diff: New file.
* admin/merge-gnulib (GNULIB_TOOL_FLAGS): Set --local-dir to
admin/gnulib-patches.
* lib/gnulib.mk.in: Update from Gnulib.
* lib/stdalign.in.h: Remove. This file was already removed in
commit b429274c5b (2023-02-04)
but was brought back mistakenly by a merge from emacs-29 in
commit ecf08f0621 (2024-01-02).
* nt/inc/stdalign.h: Don’t mention removed file in comment.
Instead of worrying about whether malloc and realloc yield a
non-null pointer when given size 0 (the traditional behavior
recommended by Doug McIlroy, and the only behavior that makes
sense for Emacs), let Gnulib arrange for the traditional behavior.
* admin/merge-gnulib (GNULIB_MODULES): Add malloc-gnu (which we
were already depending on indirectly) and realloc-posix.
* lib/gnulib.mk.in, m4/gnulib-comp.m4:
Regenerate by running admin/merge-gnulib.
