3d15181e	2021-03-01T00:27:25	unlocked-io: do not redefine getc_unlocked etc. I ran into this problem on AIX 7.1 with GNU Tar, which enables visibility of getc_unlocked etc. after testing whether they’re declared, causing argp-namefrob.h and unlocked-io.h to redefine the macros. * lib/argp-namefrob.h, lib/unlocked-io.h: (clearerr_unlocked, feof_unlocked ferror_unlocked) (fflush_unlocked, fgets_unlocked, fputc_unlocked, fputs_unlocked) (fread_unlocked, fwrite_unlocked, getc_unlocked, getchar_unlocked) (putc_unlocked, putchar_unlocked): Do not define if already defined.
4e7f59b2	2021-03-01T00:24:05	parse-datetime2: new module This splits the old parse-datetime into two parts; the first is parse-datetime2 which supports all the new bells and whistles, the second is parse-datetime, which reverts to its original intent. This avoids some bogus diagnostics when build GNU Tar with gcc -flto -fanalyze and with --enable-gcc-warnings. And it slims down the executable a bit. * NEWS: Mention this. * lib/parse-datetime.y (parser_control) [!GNULIB_PARSE_DATETIME2]: Omit parse_datetime_debug member. (debugging): New function. Use it everywhere the old code would load parse_datetime_debug. (parse_datetime_body): New static function, with the body of the old parse_datetime2. Set pc.parse_datetime_debug only if GNULIB_PARSE_DATETIME2. (parse_datetime2, parse_datetime): Use this new function. (parse_datetime2) [!GNULIB_PARSE_DATETIME2]: Remove.

0a6dc302	2021-02-15T04:25:38	simple-atomic: New module. * lib/simple-atomic.h: New file. * lib/simple-atomic.c: New file, based on lib/asyncsafe-spin.c. * modules/simple-atomic: New file.
74a0cdfe	2021-02-15T03:41:12	Fix distinction of 32-bit/64-bit mode with xlc 13.1.3 on AIX. * m4/host-cpu-c-abi.m4 (gl_HOST_CPU_C_ABI, gl_HOST_CPU_C_ABI_32BIT): Test __LP64__ instead of _ARCH_PPC64. * m4/lib-ld.m4 (AC_LIB_PROG_LD): Likewise. * lib/stddef.in.h: Likewise.
0b38e1d6	2021-02-08T23:18:34	stddef: Fix test-stddef compilation error on MidnightBSD/x86. * lib/stddef.in.h (_GL_STDDEF_ALIGNAS, rpl_max_align_t, max_align_t): Don't ignore HAVE_MAX_ALIGN_T if the compiler is clang.
a002cbb9	2021-02-05T17:08:45	regex: fix comment location * lib/regexec.c (update_regs): Move comment.
7256c713	2021-02-05T17:08:29	regex: debug check for set member duplicates * lib/regex_internal.c (re_node_set_insert): Add a DEBUG_ASSERT that would have caught some recently-fixed performance bugs that caused sets to contain duplicate members.
70b673eb	2021-02-05T17:08:10	regex: fix longstanding backref match bug This fixes a longstanding glibc bug concerning backreferences <https://sourceware.org/11053> (2009-12-04). * lib/regexec.c (proceed_next_node, push_fail_stack) (pop_fail_stack): Push and pop the previous registers as well as the current ones. All callers changed. (set_regs): Also pop if CUR_NODE has already been checked, so that it does not get added as a duplicate set entry. (update_regs): Fix comment location. * tests/test-regex.c (tests): New constant. (bug_regex11): New test function. (main): Bump alarm value. Call new test function.
f5596242	2021-02-05T16:35:46	regex: avoid duplicate in espilon closure * lib/regcomp.c (calc_eclosure_iter): Insert NODE into epsilon closure first rather than last. Otherwise, the epsilon closure might contain a duplicate of NODE.
388d9432	2021-02-05T16:35:46	regex: make it easier to merge into glibc * lib/regex_internal.h [_LIBC]: Do not include Gnulib’s dynarray.h.
d6f9ba54	2021-02-05T16:35:45	regex: minor refactoring * lib/regexec.c (proceed_next_node): Use more-local decls.
37f2bbbe	2021-02-05T16:35:45	regex: avoid undefined behavior * lib/regexec.c (pop_fail_stack): If the stack is empty, return -1 instead of indulging in undefined behavior. This simplifies callers, and avoids undefined behavior in some cases (see glibc bug 11053, though this change does not fix that overall bug).
607c71a6	2021-02-05T16:35:45	regex: improve comments * lib/regexec.c: Add and correct comments about return values.
24446f2d	2021-01-31T12:42:47	relocatable-prog-wrapper: Update after recent changes. * lib/relocwrapper.c: Update comments. * modules/relocatable-prog-wrapper (Files): Add lib/scratch_buffer.h, lib/malloc/scratch_buffer, lib/malloc.c, lib/realloc.c, lib/free.c, lib/mempcpy.c, lib/rawmemchr.c, m4/lstat.m4. Remove lib/lstat.c. (Depends-on): Add c99, eloop-threshold, fcntl-h, idx, intprops, libc-config, stddef, sys_stat. Remove alloca-opt. (configure.ac): Invoke gl_FUNC_MALLOC_POSIX, gl_FUNC_REALLOC_POSIX, gl_FUNC_FREE, gl_FUNC_MEMPCPY, gl_FUNC_RAWMEMCHR. lib/canonicalize-lgpl.c (memmove): Undefine in the relocwrapper. * build-aux/install-reloc (func_create_wrapper): Compile also malloc/scratch_buffer_*.c, malloc.c, realloc.c, free.c, mempcpy.c, rawmemchr.c. Don't compile lstat.c.
a12d5baf	2021-01-31T12:42:33	Make it possible to compile rawmemchr.c separately, unconditionally. * lib/rawmemchr.c: Don't define rawmemchr if not needed.
9c86ea67	2021-01-31T12:42:21	Make it possible to compile mempcpy.c separately, unconditionally. * lib/mempcpy.c: Don't define mempcpy if not needed.
3dfe86d1	2021-01-31T12:41:33	Make it possible to compile free.c separately, unconditionally. * m4/free.m4 (gl_FUNC_FREE): Define HAVE_FREE_POSIX. * lib/free.c: Don't define rpl_free if not needed.
64bdee09	2021-01-31T12:39:31	Make it possible to compile realloc.c separately, unconditionally. * modules/realloc-posix (configure.ac): Invoke gl_MODULE_INDICATOR. * lib/realloc.c: Don't define rpl_realloc if not needed.

195a10b5	2021-01-23T10:19:24	libc-config: port to Xcode 7 Problem reported by Mattias Engdegård in: https://lists.gnu.org/r/emacs-devel/2021-01/msg01089.html * lib/cdefs.h (__nonnull): If already defined but glibc is not in use, override the definition with Gnulib’s _GL_ATTRIBUTE_NONNULL. This is needed for Xcode 7, which has a ‘#define __nonnull _Nonnull’ builtin for backwards-compatibility with an older Xcode syntax that GNUish code never uses.
cd1b752f	2021-01-23T14:31:44	explicit_bzero: Add fallback for other compilers. * lib/explicit_bzero.c (explicit_bzero): For other compilers, invoke memset through a volatile function pointer.
ac8adb39	2021-01-23T11:22:10	explicit_bzero: Add support for clang. * lib/explicit_bzero.c (explicit_bzero): Add a compiler barrier for clang.

44ed0db8	2021-01-20T11:50:21	gc-random: Replace implementation with call to getrandom. * lib/gc-gnulib.c [GNULIB_GC_RANDOM]: Replace #include's with those needed for getrandom. (gc_init): Remove old randomness code. (gc_done): Likewise. (randomize): Rewrite using getrandom, inspired by getentropy. * m4/gc-random.m4: Remove file. * modules/crypto/gc-random: Drop gc-random.m4, gl_GC_RANDOM, and LIB_GC_RANDOM. Add conditional dependency on getrandom. * modules/crypto/gc-tests (test_gc_LDADD): Drop LIB_GC_RANDOM.
5c52f00c	2021-01-19T18:35:30	fnmatch, regex, fts: FALLTHROUGH consistency Be more consistent about how FALLTHROUGH is defined. For Gnulib, use attribute.h. For glibc, use __GNUC__ >= 7. Problem for glibc reported by Vaseeharan Vinayagamoorthy in: https://sourceware.org/pipermail/libc-alpha/2021-January/121778.html * lib/fnmatch.c (FALLTHROUGH) [_LIBC]: * lib/regex_internal.h (FALLTHROUGH) [_LIBC]: Don’t worry about Clang, as it’s not needed and provokes GCC. * lib/fts.c (FALLTHROUGH) [!_LIBC]: * lib/regex_internal.h (FALLTHROUGH) [!_LIBC]: Rely on attribute.h for FALLTHROUGH * modules/regex: Depend on attribute module.

4abfff40	2021-01-19T01:40:09	stddef: Fix compilation for max_align_t on OS/2 kLIBC. * lib/stddef.in.h [OS/2 kLIBC]: Include <cstddef> in C++ mode.
516eb87e	2021-01-19T18:41:09	sched_yield: Implement for OS/2 kLIBC. * lib/sched_yield.c (sched_yield) [OS/2 kLIBC]: New implementation.
6d07b345	2021-01-19T01:40:07	spawn: Use special invocation for <spawn.h> on OS/2 kLIBC. * lib/spawn.in.h: Use special invocation to include <spawn.h> properly on OS/2 kLIBC.
ee634876	2021-01-18T00:32:52	immutable: Implement on native Windows. * lib/immutable.h (IMMUTABLE_EFFECTIVE): Set to 1 on native Windows. * lib/immutable.c: Include <windows.h>. (CreateFileMapping): New macro. (init_pagesize, init_mmap_file, alloc_pages, free_pages): Add implementation for native Windows.

Reported by Natanael Copa <ncopa@alpinelinux.org> in <https://lists.gnu.org/archive/html/bug-gettext/2021-01/msg00021.html>. * m4/canonicalize.m4 (gl_FUNC_REALPATH_WORKS): Add a test whether // is the same as /, on Linux only. * lib/canonicalize-lgpl.c: Correct indentation of preprocessor directives. * doc/posix-functions/realpath.texi: Mention the musl 1.2.2 bug.
ee313987	2021-01-16T19:14:35	vma-iter: Port to 64-bit Haiku. * lib/vma-iter.c (vma_iterate): Adapt to changed signature of get_next_area_info.
af586b72	2021-01-13T15:46:33	verify: simplify static_assert configuration * lib/verify.h (_GL_HAVE__STATIC_ASSERT, _GL_HAVE__STATIC_ASSERT1): Do not define for C++. This should be good enough nowadays, since recent-enough C++ compilers have static_assert. (_GL_HAVE_STATIC_ASSERT_CXX11, _GL_HAVE_STATIC_ASSERT_CXX17): Remove. All uses replaced by simply checking __cpp_static_assert.
8a10202d	2021-01-12T21:11:13	verify: Use C++11 static_assert when available. Reported by Alexandre Duret-Lutz <adl@lrde.epita.fr> in <https://lists.gnu.org/archive/html/bug-gnulib/2021-01/msg00177.html>. * lib/verify.h (_GL_HAVE_STATIC_ASSERT_CXX11): New macro.

077ffc1e	2021-01-09T14:17:32	snippet/_Noreturn: port to pedantic clang Problem reported by Joe Nelson in: https://lists.gnu.org/r/bug-gnulib/2021-01/msg00152.html * doc/noreturn.texi: Improve. * lib/_Noreturn.h (_Noreturn): * m4/gnulib-common.m4 (gl_COMMON_BODY): Do not assume _Noreturn works as-is when __STRICT_ANSI__ is defined, unless __STDC_VERSION__ indicates C11 or later. * lib/_Noreturn.h (_Noreturn): Fall back on __attribute__ ((__noreturn__)) if Clang; this merges the 2020-08-10T23:53:13Zbruno@clisp.org patch to m4/gnulib-common.m4.
c738b11c	2021-01-09T08:20:17	fchmodat: Work around trailing slash bug in fchmodat() on AIX 7.2. * m4/fchmodat.m4 (gl_FUNC_FCHMODAT): In the test whether fchmodat works, also test for the trailing slashes behaviour. Define HAVE_NEARLY_WORKING_FCHMODAT if this is the only missing feature. * lib/fchmodat.c (fchmodat): If HAVE_NEARLY_WORKING_FCHMODAT, handle trailing slashes here. * modules/fchmodat (Depends-on): Sort by condition, not alphabetically. * doc/posix-functions/fchmodat.texi: Document the AIX bug.
6a00fdb4	2021-01-08T19:50:16	dynarray: work even if ‘free’ is replaced Problem reported by Darshit Shah in: https://lists.gnu.org/r/bug-gnulib/2021-01/msg00140.html * lib/malloc/dynarray-skeleton.c (DYNARRAY_FREE): New macro. Use it everywhere instead of DYNARRAY_NAME (free).
b0ebaf83	2021-01-08T17:54:30	tempname: don’t block for minutes Derived from a patch proposed by Adhemerval Zanella in: https://sourceware.org/pipermail/libc-alpha/2021-January/121302.html * lib/tempname.c (random_bits): Use GRND_NONBLOCK.
551b70f4	2021-01-08T17:31:28	tempname: sync with proposed glibc patch This is from Adhemerval Zanella in: https://sourceware.org/pipermail/libc-alpha/2021-January/121301.html * lib/tempname.c (__lxstat64): Remove. (__lstat64, __stat64): New replacement macros. All uses changed.
87ed1f9c	2021-01-08T17:17:32	regex: stop using alloca * lib/regex_internal.h: Do not include <alloca.h> or define __libc_use_alloca or alloca. Patch written by Adhemerval Zanella: https://sourceware.org/pipermail/libc-alpha/2021-January/121374.html * modules/regex (Depends-on): Remove alloca-opt.
1731fef3	2021-01-08T14:22:15	regexec: remove alloca usage in build_trtable Prompted by this different change proposed by Adhemerval Zanella: https://sourceware.org/pipermail/libc-alpha/2021-January/121373.html * lib/regexec.c (build_trtable): Prevent inlining, so that it doesn’t bloat the caller’s stack. Use auto variables instead of alloca/malloc. After these changes, build_trtable’s total stack allocation is only 20 KiB on a 64-bit machine, and this is less than glibc’s 64 KiB cutoff so there’s little point to using alloca to shrink it. Although Gnulib traditionally has used a 4 KiB cutoff, going to 20 KiB here should not be a significant problem in practice; Gnulib-using packages concerned about overflow of tiny stacks can compile with something like gcc -fstack-clash-protection. * config/srclist.txt: Comment out regexec.c for now.
b0e441b8	2021-01-08T12:01:37	scratch_buffer: add scratch_buffer_dupfree macro * lib/scratch_buffer.h (__libc_scratch_buffer_dupfree): New macro, needed to support recent changes in this module.

Include malloc/dynarray-skeleton.c. (set_regs): Use dynarray rather than alloca. * modules/regex (Depends-on): Add dynarray.
921d2ea1	2021-01-08T11:44:19	dynarray: new module * config/srclist.txt: Mention the new files. * lib/cdefs.h (__attribute_maybe_unused__): New macro, like Gnulib’s _GL_ATTRIBUTE_MAYBE_UNUSED but with glibc naming conventions. * lib/libc-config.h: Use it instead of __glibc_likely. * lib/dynarray.h, modules/dynarray: New files. * lib/malloc/dynarray-skeleton.c, lib/malloc/dynarray.h: * lib/malloc/dynarray_at_failure.c: * lib/malloc/dynarray_emplace_enlarge.c: * lib/malloc/dynarray_finalize.c, lib/malloc/dynarray_resize.c: * lib/malloc/dynarray_resize_clear.c, modules/dynarray: New files, from glibc with the following changes needed for portability to compilers that are not recent-enough GCC. * lib/malloc/dynarray_at_failure.c: Include stdlib.h, for abort. (__libc_dynarray_at_failure) [!_LIBC]: Simply abort. * lib/malloc/dynarray_emplace_enlarge.c: * lib/malloc/dynarray_resize.c: Include intprops.h, and use INT_MULTIPLY_WRAPV instead of __builtin_mul_overflow. * lib/malloc/dynarray.h (__libc_dynarray_at_failure): Use _Noreturn instead of __attribute__ ((noreturn)). * lib/malloc/dynarray_resize_clear.c: Do not include stdlib.h; it’s not needed. (__libc_dynarray_resize_clear): Do not do arithmetic on void . lib/malloc/dynarray-skeleton.c (struct DYNARRAY_STRUCT): Do not use anonymous unions, as they are not in C99. All uses changed. Use __nonnull (X) instead of __attribute__ ((nonnull X)), and __attribute_maybe_unused__ instead of __attribute__ ((unused)).
6047713a	2021-01-07T22:55:41	localename: Fix link error with duplocale on AIX 7.2 (regr. 2019-12-18). * m4/locale_h.m4 (gl_LOCALE_H_DEFAULTS): Initialize LOCALENAME_ENHANCE_LOCALE_FUNCS. * m4/intl-thread-locale.m4 (gt_FUNC_USELOCALE): Set gt_working_uselocale. (gt_INTL_THREAD_LOCALE_NAME): Set gt_fake_locales, gt_good_uselocale, gt_localename_enhances_locale_funcs, LOCALENAME_ENHANCE_LOCALE_FUNCS. Define HAVE_GOOD_USELOCALE, LOCALENAME_ENHANCE_LOCALE_FUNCS. * m4/localename.m4 (gl_LOCALENAME): Test gt_localename_enhances_locale_funcs instead of gt_nameless_locales. * modules/locale (Makefile.am): Substitute LOCALENAME_ENHANCE_LOCALE_FUNCS. * lib/locale.in.h (newlocale, duplocale, freelocale): Don't override if module 'localename' is in use but LOCALENAME_ENHANCE_LOCALE_FUNCS is 0. * lib/localename.c (HAVE_GOOD_USELOCALE): Don't define here. (get_locale_t_name, newlocale, duplocale, freelocale): Define if LOCALENAME_ENHANCE_LOCALE_FUNCS.
a4be4b42	2021-01-06T10:02:33	libc-config: simplify clang __has_* macros cdefs.h sometimes used names like __glibc_clang_has_attribute and sometimes __glibc_has_attribute. There is no need in glibc or Gnulib to distinguish clang from other compilers here, so be consistent and use the simpler names. * lib/cdefs.h (__glibc_has_builtin, __glibc_has_extension): Rename from __glibc_clang_has_builtin, __glibc_clang_has_extension. All uses changed. (__glibc_clang_has_attribute): Remove. All uses replaced by __glibc_has_attribute. * lib/libc-config.h [!__glibc_likely]: Undef them here too. This fixes a problem where __glibc_has_attribute was not undeffed.
9b8b302f	2021-01-06T11:59:57	ilogbl: Fix compilation error with xlclang on AIX 7.2. * lib/math.in.h (ilogbl): Undefine macro before declaration.
c6d61838	2021-01-06T07:23:14	pipe-filter-gi: Fix test failure on AIX 7.2. * lib/pipe-filter-aux.h (SSIZE_MAX) [AIX]: Set to 4096.
05bee3e8	2021-01-06T06:16:22	utimens, utimensat, fdutimensat: Avoid test failures on AIX 7.2. * lib/utimecmp.c (utimecmpat): On AIX, declare equality when the two times differ by less than 0.01 seconds. * tests/test-futimens.h (test_futimens): Pass UTIMECMP_TRUNCATE_SOURCE flag.

Add a test for trailing slash handling. Improve cross-compilation guesses. Conditionally define HAVE_NEARLY_WORKING_UTIMENSAT. * lib/utimensat.c (rpl_utimensat): Add alternative implementation when HAVE_NEARLY_WORKING_UTIMENSAT is defined. * lib/utimens.c: Use the overridden utimensat when HAVE_NEARLY_WORKING_UTIMENSAT is defined. * doc/posix-functions/utimensat.texi: Mention the AIX bug.
776af40e	2021-01-05T13:12:39	libc-config: merge from glibc Use a better way of keeping glibc <sys/cdefs.h> and gnulib lib/cdefs.h mostly in sync, by using lib/cdefs.h only on platforms where <sys/cdefs.h> does not work well enough for Gnulib. * lib/cdefs.h: Go back to using _SYS_CDEFS_H rather than _GL_DEFS_H as an include guard. (__THROW, __THROWNL, __NTH, __NTHNL): Define to noexcept for C++11 and later. (__glibc_objsize, __glibc_objsize0): New, for _FORTIFY_SOURCE=3. (__warndecl): Remove. (__attribute_copy__): New macro, for GCC 9 support.

regexec: remove alloca usage in build_trtable Prompted by this different change proposed by Adhemerval Zanella: https://sourceware.org/pipermail/libc-alpha/2021-January/121373.html * lib/regexec.c (build_trtable): Prevent inlining, so that it doesn’t bloat the caller’s stack. Use auto variables instead of alloca/malloc. After these changes, build_trtable’s total stack allocation is only 20 KiB on a 64-bit machine, and this is less than glibc’s 64 KiB cutoff so there’s little point to using alloca to shrink it. Although Gnulib traditionally has used a 4 KiB cutoff, going to 20 KiB here should not be a significant problem in practice; Gnulib-using packages concerned about overflow of tiny stacks can compile with something like gcc -fstack-clash-protection. * config/srclist.txt: Comment out regexec.c for now.

fnmatch: merge from glibc + proposal This merges the change proposed by Adhemerval Zanella in: https://sourceware.org/pipermail/libc-alpha/2020-December/121212.html which fixes a Gnulib bug that led to a failed assert. * lib/fnmatch_loop.c (EXT): Use signed level, not unsigned, and check that it stays nonnegative. Use __flexarr instead of FLEXIBLE_ARRAY_MEMBER, to port better to glibc. * tests/test-fnmatch.c (main): New test cases, taken from glibc.

canonicalize: fix size overflow treatment This also has some minor cleanups. * lib/canonicalize-lgpl.c, lib/canonicalize.c: No need to include stddef.h, since the code no longer refers directly to ptrdiff_t. * lib/canonicalize-lgpl.c (realpath_stk): * lib/canonicalize.c (canonicalize_filename_mode_stk): Treat size overflow like other out-of-memory. * lib/canonicalize.c: No need to include stdlib.h, since the code no longer refers to stdlib.h functions (other than those that canonicalize.h must declare). * lib/canonicalize.c (canonicalize_filename_mode_stk): Do not bother terminating the string result on error.
