* glob: merge from glibc with Zanella glob changesPaul Eggert2017-08-231-9/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Merge glob from glibc, with changes for glob proposed by Adhemerval Zanella in the thread starting here: https://sourceware.org/ml/libc-alpha/2017-08/msg01079.html plus some fixes for this merge. * lib/flexmember.h: Change license wording to something that works unchanged in Glibc, since this code might be used in Glibc and this will minimize 'diff' output. * lib/glob_internal.h, lib/glob_pattern_p.c, lib/globfree.c: New files, ported from glibc. * lib/glob_pattern_p.c, lib/globfree.c, lib/glob.c [!_LIBC]: Include <config.h> first. * lib/glob-libc.h (_Restrict_): Remove. All uses replaced with __restrict. (__size_t): Remove. All uses replaced by size_t. (size_t): Define by defining __need_size_t and including <stddef.h>. This should work even in non-glibc platforms, where any name pollution is OK. Use __USE_MISC instead of __USE_BSD || __USE_GNU. (struct stat64): Don’t worry about __GLOB_GNULIB. (glob, globfree, glob_pattern_p): Remove macros for __USE_FILE_OFFSET64 && __GNUC__ < 2 && !defined __GLOB_GNULIB case. Remove _GL_ARG_NONNULL as GNU behavior is to accept NULL but set errno. * lib/glob.c (_GL_ARG_NONNULL) [!_LIBC]: Remove. All uses removed since the glibc behavior works on null pointers. Do not include stdio.h; old SunOS is irrelevant now. Do not worry about GLOB_ONLY_P as we now mimic glibc here. Include glob_internal.h. (D_INO_TO_RESULT): Depend on (_LIBC || D_INO_IN_DIRENT), not ((POSIX || WINDOWS32) && !__GNU_LIBRARY__). The latter probably worked only coincidentally. (attribute_hidden, __attribute_noinline__, __glibc_unlikely): Remove macros; now done in glob.in.h. (size_add_wrapv): Do not use __builtin_add_overflow if __ICC. (glob): Properly initialize glob structure with GLOB_BRACE|GLOB_DOOFFS (bug 20707). Remove old code using SHELL since Bash no longer uses this. (glob, prefix_array): Separate MS code better. (glob, glob_in_dir): Use C99 decls before statements when glibc does. (glob_in_dir): Remove old Amiga and VMS code. (globfree, __glob_pattern_type, __glob_pattern_p): Move to separate files. * lib/glob.in.h (attribute_hidden, __attribute_noinline__) (__glibc_unlikely): Move here from glob.c. (__restrict): New macro here, replacing the _Restrict_ in glob.c. (weak_alias): New macro. (__size_t): Remove. All uses replaced by size_t. * modules/d-ino (License): Now LGPLv2+, for compatibility with glob. * modules/flexmember (License): Now LGPLv2+, which it should have been anyway since flexmember.h is not unlimited-license. * modules/glob (Files): Add +lib/glob_internal.h, lib/glob_pattern_p.c, lib/globfree.c. (Depends-on): Remove snippet/arg-nonnull.
* version-etc: new yearPaul Eggert2017-01-011-1/+1
| | | | | | | | | | * build-aux/gendocs.sh (version): * doc/gendocs_template: * doc/gendocs_template_min: * doc/gnulib.texi: * lib/version-etc.c (COPYRIGHT_YEAR): Update copyright dates by hand in templates and the like. * all files: Run 'make update-copyright'.
* flexmember: new macro FLEXALIGNOFPaul Eggert2016-09-071-6/+9
| | | | | | * lib/flexmember.h: Include <stddef.h>, for offsetof. (FLEXALIGNOF): Rename from _GL_XALLOC_ALIGNOF, as Emacs can use this macro. Update comments.
* flexmember: port better to GCC + valgrindPaul Eggert2016-09-071-0/+39
With a char[] flexible array member in a struct with nontrivial alignment, GCC-generated code can access past the end of the array, because GCC assumes there are padding bytes to get the struct aligned. So the common idiom of malloc (offsetof (struct s, m), n) does not properly allocate an n-byte trailing member, as malloc’s argument should be the next multiple of alignof (struct s). See GCC Bug#66661: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66661 Although C11 apparently permits this GCC optimization (i.e., there was a bug in Gnulib not in GCC), possibly this is a defect in C11. See the thread containing: https://gcc.gnu.org/ml/gcc-patches/2016-09/msg00317.html * lib/flexmember.h: New file. * lib/fnmatch.c, lib/fts.c, lib/glob.c, lib/idcache.c: * lib/localename.c, lib/time_rz.c: Include flexmember.h. * lib/fnmatch_loop.c (struct patternlist): * lib/localename.c (struct hash_node): Use FLEXIBLE_ARRAY_MEMBER. * lib/fnmatch_loop.c (EXT): * lib/fts.c (fts_alloc): * lib/glob.c (glob_in_dir): * lib/idcache.c (getuser, getuidbyname, getgroup, getgidbyname): * lib/localename.c (gl_lock_define_initialized): * lib/time_rz.c (tzalloc): Use FLEXSIZEOF instead of offsetof. * m4/flexmember.m4 (AC_C_FLEXIBLE_ARRAY_MEMBER): Check that the size of the struct can be taken. * modules/flexmember (Files): Add lib/flexmember.h. * modules/fnmatch, modules/glob, modules/localename (Depends-on): Add flexmember.
