* regex: assume RE_ENABLE_I18NPaul Eggert2021-11-241-40/+0
| | | | | | | | | | | These days there is no longer any need to port to platforms lacking iswctype etc., since Gnulib now has substitutes. * config/srclist.txt: Comment out regex_internal.c and regex_internal.h for now, since they no longer match glibc. The intent is to merge them again soon. * lib/regex_internal.h (RE_ENABLE_I18N): Remove. All uses changed to assume that RE_ENABLE_I18N is 1. * modules/regex (Depends-on): Add iswctype.

| | | | | | | | * lib/regex_internal.c (build_wcs_upper_buffer): Do not assume that converting single-byte character to upper yields a single-byte character. This is not true for Turkish, where towupper (L'i') yields L'İ', which is not single-byte. * tests/test-regex.c (main): Test for this bug.

* regex: port to recently proposed glibc regex mergePaul Eggert2018-06-281-1/+11
| | | | | | | | | | | | | | | | | | | | | | | | This patch is inspired by Adhemerval Zanella's recent proposal https://www.sourceware.org/ml/libc-alpha/2018-06/msg00905.html to merge glibc and Gnulib regex. It aims to simplify the merge on the glibc side, without keeping Gnulib portable. * lib/regex.h: Fix a problem with glibc installed-header checking, as follows: (_Restrict_): Prefer __restrict if defined or if GCC 2.95 or later. (_Restrict_arr_): Prefer __restrict_arr if defined, otherwise prefer _Restrict_ if C99 or GCC 3.1 or later (but not C++). * lib/regex_internal.c (re_string_realloc_buffers, build_wcs_buffer) (build_wcs_upper_buffer, build_upper_buffer) (re_string_translate_buffer, re_string_context_at): Move decls here from lib/regex_internal.h, for glibc internal tests. (build_wcs_upper_buffer): Use __wcrtomb, not wcrtomb, fixing glibc BZ #18496. * lib/regex_internal.h (lock_fini) [_LIBC]: Cast to 0 to pacify -Wunused-value. (bitset_set, bitset_clear, bitset_contain, bitset_empty) (bitset_set_all, bitset_copy, bitset_not, bitset_merge) (bitset_mask): Now static inline, and without any __attribute__ ((unused)) decoration, for glibc internal tests.

* regex: make it closer to libcPaul Eggert2016-02-191-21/+20
| | | | | | | | | | | | | | | Make Idx a signed type, rather than possibly unsigned. The unsignedness was not really buying us anything, since the code overflows for other reasons before getting to PTRDIFF_MAX. Making it signed allows us to use -1 and -2 with abandon, like libc does, thus lessening the number of differences between gnulib and libc. Also, it should help avoid gratuitous warnings like the one reported by Nelson H. F. Beebe in: http://bugs.gnu.org/22702 * lib/regex.h (__re_idx_t): Remove. All uses changed to regoff_t. * lib/regex_internal.h (SSIZE_MAX): Define if <limits.h> doesn't. (IDX_MAX) [_REGEX_LARGE_OFFSETS]: Now SSIZE_MAX. (REG_MISSING, REG_ERROR, REG_VALID_INDEX, REG_VALID_NONZERO_INDEX): Remove. Revert all uses to their libc versions.

* Use consistent style to check DEBUG macro in regex_internal.cSiddhesh Poyarekar2014-08-011-2/+2
| | | | | | | | | | | | The DEBUG macro is checked using both #if and #ifdef in regex_internal.c. Make this consistent with mktime, where we use "#if defined DEBUG && DEBUG", to be compatible with gnulib as well as glibc style. regex: Make #if/#ifdef usage consistent for DEBUG * lib/regex_internal.c: Use "#if defined DEBUG && DEBUG" instead of the inconsistent usage of #if and #ifdef as that works with both Glibc and Gnulib's style.
* regex: port to OS X 10.8.5 en_US.UTF-8 localePaul Eggert2014-03-061-10/+5
| | | | | | | | | | | | | This fixes a bug when ignoring case and when comparing the titlecase letter 'Lj' (U+01C8 LATIN CAPITAL LETTER L WITH SMALL LETTER J) to the corresponding uppercase letter 'LJ' (U+01C7 LATIN CAPITAL LETTER LJ). In the OS X 10.8.5 en_US.UTF-8 locale, the titlecase letter is neither lowercase nor uppercase, but uppercasing the titlecase letter (via towupper) yields the uppercase letter, so the two letters should match when ignoring case. Problem reported by Jim Meyering in <http://debbugs.gnu.org/16911#16>. * lib/regex_internal.c (build_wcs_upper_buffer, build_upper_buffer): Don't test whether a character is lowercase before uppercasing it.

* regex: merge glibc changesPaul Eggert2012-12-301-9/+10
| | | | | | | | | Also, copy the license wording from glibc. This simplifies merging changes. gnulib-tool will change the wording to GPL as appropriate, when importing it to other packages. The only glibc change made since the last merge, which needs merging, is: 2012-05-24 Andreas Schwab <schwab@linux-m68k.org> * lib/regex_internal.h (gettext): Remove use of INTUSE.
* regex: no 'static inline'Paul Eggert2012-11-291-1/+1

(inline) [__GNUC__ < 3 && _LIBC]: Remove macro; no longer needed.

(init_word_char): Work even if bitset words are not exactly 32 or 64 bits wide. Don't assume there are no padding bits. * lib/regex.c [_LIBC]: Do not include <config.h>. [!_LIBC]: Add pragmas to ignore -Wsuggest-attributes=pure and -Wtype-limits. * lib/regex.h (__USE_GNU): Renamed from __USE_GNU_REGEX, to avoid needless disagreement with glibc. All uses changed. Define it to 1 only if _GNU_SOURCE, to match glibc. (_REG_RM_NAME): Remove; no longer needed, since the names in question are now all protected by __USE_GNU. (_REG_RE_NAME): Remove; replaced by glibc's __REPB_PREFIX. (REG_TRANSLATE_TYPE): Remove; replaced by glibc's __RE_TRANSLATE_TYPE. * lib/regex_internal.h (MIN): New macro. 2012-01-03 Ulrich Drepper <drepper@gmail.com> * lib/regcomp.c (init_word_char): Optimize regex a bit. 2011-12-30 Jakub Jelinek <jakub@redhat.com> * lib/regex_internal.c (re_string_fetch_byte_case): Fix up regcomp/regexec. The problem is that parse_bracket_symbol is miscompiled, and it turns out it is because of an incorrect attribute on re_string_fetch_byte_case. Unlike re_string_peek_byte_case, this one is really not pure, it modifies memory (increments pstr->cur_idx), and with the pure attribute GCC assumed it doesn't and it cached the presumed value of regexp->cur_idx in a variable across the for (;; ++i) { if (i >= BRACKET_NAME_BUF_SIZE) return REG_EBRACK; if (token->type == OP_OPEN_CHAR_CLASS) ch = re_string_fetch_byte_case (regexp); else ch = re_string_fetch_byte (regexp); if (re_string_eoi(regexp)) return REG_EBRACK; if (ch == delim && re_string_peek_byte (regexp, 0) == ']') break; elem->opr.name[i] = ch; } 2011-11-29 Andreas Schwab <schwab@redhat.com> * lib/regcomp.c (build_equiv_class): Fix access after end of search string in regex matcher. 2011-11-12 Ulrich Drepper <drepper@redhat.com> * lib/regex_internal.c, lib/regex_internal.h: Fix warnings in regex. 2011-10-12 Ulrich Drepper <drepper@redhat.com> * lib/regcomp.c (parse_branch): One more regex memory leak fixed. 2011-10-11 Ulrich Drepper <drepper@redhat.com> * lib/regcomp.c (parse_branch, parse_sub_exp): More regex memory leak fixes and tests. (parse_sub_exp, parse_bracket_exp): Fix memory leak for some invalid regular expressions. 2011-05-28 Ulrich Drepper <drepper@gmail.com> * lib/regex_internal.c, lib/regexec.c: Fix unnecessary overallocation due to incomplete character. When incomplete characters are found at the end of a string the code ran amok and allocated lots of memory. Stricter limits are now in place. 2011-05-20 Reuben Thomas <rrt@sc3d.org> * lib/regex.h: Update documentation. 2011-05-16 Aharon Robbins <arnold@skeeve.com> * lib/regex.h: Update RE_SYNTAX*_AWK constants. 2010-05-05 Andreas Schwab <schwab@redhat.com> * lib/regexec.c (find_collation_sequence_value): Fix lookup of collation sequence value during regexp matching. 2010-01-22 Ulrich Drepper <drepper@redhat.com> * lib/regex_internal.c (re_dfa_add_node): Extend overflow detection. 2008-01-16 Ulrich Drepper <drepper@redhat.com> * lib/regex.h: Cleanup namespace. 2007-11-26 Ulrich Drepper <drepper@redhat.com> * lib/regex.h (REG_ENOSYS): Define REG_ENOSYS also for __USE_XOPEN2K. 2007-08-26 Ulrich Drepper <drepper@redhat.com> * lib/regex_internal.h: Prevent some declarations and definitions to be seen when used in tests. 2005-05-06 Ulrich Drepper <drepper@redhat.com> * lib/regex_internal.h: Include bits/libc-lock.h or define dummy __libc_lock_* macros if not _LIBC. (struct re_dfa_t): Add lock.
