* Make autogen a shell function tooPaul Eggert2022-12-274-450/+912
| | | | | | | | | | 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’. (autogen): New function, containing the top level of the old top/autogen.sh.
* Move scriptversion= lines up in scriptsPaul Eggert2022-12-275-12/+12

| | | | | | | | * m4/gnulib-common.m4 (gl_COMMON_BODY): In _GL_ATTRIBUTE_DEALLOC_FREE, with GNU C++, cast the 'free' function. * lib/string.in.h (_GL_ATTRIBUTE_DEALLOC_FREE): With GNU C++, cast the 'free' function. * lib/wchar.in.h (_GL_ATTRIBUTE_DEALLOC_FREE): Likewise.

* largefile: sync from Autoconf masterPaul Eggert2022-12-256-209/+287
| | | | | | | | | | | | | | | | | | * 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.

* extensions: enable some C23 Annex F functionsPaul Eggert2022-12-242-3/+13
| | | | | | * 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: deprecatePaul Eggert2022-12-246-20/+38
| | | | | | | C23 says <stdnoreturn.h> 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.
* doc: C2x → C23Paul Eggert2022-12-246-10/+10

* file-has-acl: improve recent NFSv4 supportPaul Eggert2022-12-235-136/+138
| | | | | | | | | | | | | | | | | | | | | | | | 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).
* posix_spawnp-tests: fix filename typoPaul Eggert2022-12-222-1/+10
| | | | | | | | 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.
* file-has-acl: Basic support for checking NFSv4 ACLs in Linux.Ondrej Valousek2022-12-225-0/+151
| | | | | | | | | * lib/acl-internal.h (acl_nfs4_nontrivial): New declaration. * lib/acl-internal.c (acl_nfs4_nontrivial): New function. * lib/file-has-acl.c: Include <arpa/inet.h>. (XATTR_NAME_NFSV4_ACL, TRIVIAL_NFS4_ACL_MAX_LENGTH): New macros. (file_has_acl): Test for NFSv4 ACLs. * doc/acl-nfsv4.txt: New file.
* Port __has_c_attribute to strict C23Paul Eggert2022-12-212-23/+40
| | | | | | | * 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: deprecatePaul Eggert2022-12-216-0/+26
| | | | | | | | 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.

* memset_explicit: port to older MS-WindowsPaul Eggert2022-12-172-9/+10
| | | | | | | | | * 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.
* Update users.txt.Bruno Haible2022-12-102-0/+6
| | | | * users.txt: Add lbzip2.
* fts: make debug version compilable againPaul Eggert2022-12-092-22/+55
| | | | | | | | | | | | | | | | | | 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 <stdint.h> (not needed, since we include <stdint.h>) 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.
* verify: update __STDC_VERSION__ as per C23Paul Eggert2022-12-072-1/+10
| | | | | | | | 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.
* fts: fix race + mishandling of fstatat failurePaul Eggert2022-12-062-8/+34
| | | | | | | | | | | I hope this fixes a Luke Dashjr coreutils bug report about ext4 ramdisks; see “9.1: du Aborted (corrupt filesystem)” <https://debbugs.gnu.org/59821>. * 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_closedirPaul Eggert2022-12-062-6/+5
| | | | * lib/fts.c (fts_build): Refactor to omit goto.
* fts: clarify ISSETPaul Eggert2022-12-062-1/+6
| | | | * lib/fts.c (ISSET): Refactor to clarify boolean usage.
* argp: Correct documentation.Bruno Haible2022-12-0611-40/+46
| | | | | | Reported by José E. Marchesi <jemarch@gnu.org>. * doc/glibc-functions/argp_*.texi: Mention the 'argp' module.
* doc: poll: document poll of special files not supported on macOSPádraig Brady2022-12-023-2/+9
| | | | | | * doc/posix-functions/poll.texi: Reinstate (updated) macOS info, removed in recent cleanup re removal of support for Mac OS X <= 10.4. * m4/poll.m4: Update macOS to latest tested version.
* add new ronna and quetta SI prefixesPádraig Brady2022-11-293-2/+21
| | | | | | | | As voted for in Nov 2022 by the BIPM: https://www.bipm.org/en/cgpm-2022/resolution-3 * lib/human.c: Add Ronna (10^27), and Quetta (10^30) to the prefix list. * lib/xstrtol.c (__xstrtol): Likewise.

| | | | | * doc/glibc-functions/explicit_bzero.texi: Say that memset_explicit is preferred in new code.
* read-file: use memset_explicitPaul Eggert2022-11-283-7/+13
