Paul Eggert 5508825f 2018-06-29T15:34:57 regex: glibc does not use intprops.h Maybe we can talk glibc into using intprops.h someday, but now doesn’t seem to be a good time. * lib/regcomp.c (TYPE_SIGNED): Remove; regex_internal.h now defines. * lib/regex_internal.h [_LIBC]: Do not include intprops.h. (TYPE_SIGNED, INT_ADD_WRAPV): New macros.
Paul Eggert f59be416 2018-06-28T12:23:31 regex: port to recently proposed glibc regex merge 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.

Paul Eggert 6dc8556f 2017-11-20T15:56:22 regex: merge from glibc * lib/regcomp.c (__regcomp, __regfree) [_LIBC]: Now hidden. * lib/regex_internal.h (internal_function): Remove. All uses removed.

Paul Eggert f7795760 2017-07-26T09:12:29 regex: work with GCC7's -Werror=implicit-fallthrough= * lib/regex_internal.h (FALLTHROUGH): New macro. * lib/regcomp.c (peek_token_bracket, parse_expression): * lib/regexec.c (check_node_accept): Use it.
Paul Eggert 469b0d23 2017-04-16T12:43:20 regex: port better to Solaris 10 Solaris 10 <locale.h> includes <libintl.h>, which #defines gettext, and this causes a double #define. Problem reported by Gavin Smith in: http://lists.gnu.org/archive/html/bug-gnulib/2017-04/msg00056.html * lib/regex_internal.h (gettext): #undef before #defining.
Paul Eggert a3fd683d 2017-01-01T02:59:23 version-etc: new year * 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'.
Paul Eggert 005973d6 2016-12-16T14:52:59 builtin-expect: new module Fix fnmatch to use it. Problem reported for z/OS by Daniel Richard G. * lib/fnmatch.c (__builtin_expect): * lib/glob.c (__builtin_expect): * lib/grantpt.c (__builtin_expect) [!_LIBC]: * lib/memmem.c (__builtin_expect) [!_LIBC]: * lib/scandir.c (__builtin_expect): * lib/strstr.c (__builtin_expect) [!_LIBC]: Remove macro; config.h now does this. * lib/gl_anytreehash_list1.h (add_to_bucket): * lib/regex_internal.h (BE): Assume __builtin_expect. * m4/builtin-expect.m4, modules/builtin-expect: New files. * modules/avltreehash-list, modules/fnmatch, modules/glob: * modules/grantpt, modules/memmem-simple, modules/rbtreehash-list: * modules/scandir, modules/strstr-simple: Depend on builtin-expect.
Paul Eggert ea7015f6 2016-12-16T09:34:02 regex: fix integer-overflow bug in never-used code Problem reported by Clément Pit–Claudel in: http://lists.gnu.org/archive/html/emacs-devel/2016-12/msg00654.html * lib/regex_internal.h: Include intprops.h. * lib/regexec.c (re_search_2_stub): Use it to avoid undefined behavior on integer overflow. * modules/regex (Depends-on): Add intprops.
Paul Eggert f97745b0 2016-02-19T09:27:41 regex: make it closer to libc 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.

Paul Eggert a8ba7140 2014-06-13T08:30:48 regex: don't be multithreaded if USE_UNLOCKED_IO. Problem reported by Michael Felt in: http://bugs.gnu.org/17773 * lib/regex_internal.h: Do not use multithreaded version if USE_UNLOCKED_IO is defined. This is a hack, but it works around a porting bug with coreutils 8.22 on AIX 7.1.

Jim Meyering 974b76b7 2013-10-21T14:54:30 regex: also remove dependency on HAVE_WCSCOLL * lib/regex_internal.h: Remove final vestige of the wcscoll dependency.
Paul Eggert da8d59ee 2013-07-09T11:35:01 regex: port to --with-included-regex --enable-gcc-warnings non-threaded * lib/regex_internal.h (lock_fini, lock_lock): Rework to avoid gcc warnings in the non-threaded case. Reported by Charlie Brown in <http://lists.gnu.org/archive/html/bug-gnulib/2013-07/msg00015.html>.

Paul Eggert 55ba71f4 2013-05-29T10:24:17 regex: adapt to locking regime instead of depending on pthread Instead of depending on pthread, adapt to whatever thread modules are in use. Problem reported by Ludovic Courtès in <http://lists.gnu.org/archive/html/bug-gnulib/2013-05/msg00082.html> and by Mats Erik Andersson in <http://lists.gnu.org/archive/html/bug-gnulib/2013-05/msg00100.html>. * lib/regex_internal.h (lock_define, lock_init, lock_fini): Support either the 'lock' module, or the 'pthread' module, or no module.

Paul Eggert 9ceceed2 2013-05-19T14:26:05 regex: fix dfa race in multithreaded uses Problem reported by Ludovic Courtès in <http://lists.gnu.org/archive/html/bug-gnulib/2013-05/msg00058.html>. * lib/regex_internal.h (lock_define, lock_init, lock_fini): New macros. All uses of __libc_lock_define, __libc_lock_init changed to use the first two of these. (__libc_lock_lock, __libc_lock_unlock): New macros, for non-glibc platforms. (struct re_dfa_t): Define the lock unconditionally. * lib/regexec.c (regexec, re_search_stub): Remove some now-incorrect '#ifdef _LIBC"s. * modules/regex (Depends-on): Add pthread, if we use the included regex. * lib/regcomp.c: Do actions that are not needed for glibc, but may be needed elsewhere.

(inline) [__GNUC__ < 3 && _LIBC]: Remove macro; no longer needed.
Paul Eggert d4903bb0 2012-06-26T15:16:07 regex: use locale-independent comparison for codeset name See Bruno Haible's comment in <http://bugs.gnu.org/10305#120>. * lib/regcomp.c (init_dfa): Use just ASCII case comparison for codeset name. * lib/regex_internal.h: Do not include <strings.h>, since we no longer use strcasecmp. * modules/regex (Depends-on): Remove strcase.
Bruno Haible 2457d7ca 2012-06-26T19:46:15 argp, regex: Ensure strcasecmp gets declared. * lib/argp-help.c: Include <strings.h>. * lib/regex_internal.h: Likewise. Reported and suggested by Joachim Schmitz <jojo@schmitz-digital.de>.

Paul Eggert 51096a4b 2012-02-07T23:06:43 regex: rely on stdint.h for SIZE_MAX * lib/regex_internal.h (SIZE_MAX): Remove; stdint.h supplies this now.
Paul Eggert 5a460138 2012-02-07T22:47:01 regex: merge glibc changes * lib/regcomp.c (init_dfa): Tighten overflow checks to test for IDX_MAX too, since IDX_MAX can be much less than SIZE_MAX. (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.

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.

Paul Eggert 8335a4d6 2006-04-10T06:43:33 Merge regex changes from libc, removing some of our POSIX-conformance changes that were rejected and redoing them in a less-intrusive way. * lib/regcomp.c (re_compile_internal, init_dfa): Length arg is now size_t, not Idx. All uses changed. (peek_token): Forward decl now says internal_function. (__re_error_msgid, __re_error_msgid_idx): Now static rather than extern with attribute_hidden. (re_compile_pattern) [!defined _LIBC]: Use K&R-style defn. For some reason libc prefers K&R style defns for external functions. (regerror) [!defined _LIBC]: Likewise. (re_set_syntax, re_compile_fastmap, regcomp, regfree, re_comp): (seek_collating_symbol_entry, lookup_collation_sequence_value): (build_range_exp, build_collating_symbol): Use K&R-style defn.

Don't depend on _REGEX_SOURCE any more; depend on _GNU_SOURCE instead. Don't depend on VMS; depend on __VMS instead, for POSIX namespace cleanness. (regoff_t): Define to ssize_t, not long int. Remove the REG_ macros named below. Instead, make the old names (e.g., RE_BACKSLASH_ESCAPE_IN_LISTS) visible only if __USE_GNU_REGEX.

Paul Eggert e48d8b47 2006-01-10T20:14:43 * regex_internal.h (BITSET_WORD_BITS): Work around a bug in 64-bit PGC (before version 6.1-2), where the preprocessor mishandles large unsigned values as if they were signed.
Paul Eggert b7f90374 2005-09-25T04:20:16 * regex_internal.h (__GNUC_PREREQ, always_inline, inline, pure): Remove. (__attribute): Define to empty unless GCC 3.1 or later. This works around a core dump on OpenBSD 3.4, which has GCC 2.95.3, which dumps core when given __attribute__(()). It also simplifies other tests, since we really don't want to bother with worrying about which ancient version of GCC supported what. Original problem reported by Yoann Vandoorselaere, with part of the fix suggested by Derek Price.
Paul Eggert ecc2024e 2005-09-24T23:01:17 (__attribute): Define to nothing for GCC 2. This works around a core dump on OpenBSD 3.4, which has GCC 2.95.3, which dumps core when given __attribute__(()).
Paul Eggert 7c3f8da8 2005-09-23T04:15:13 Sync from coreutils. * .cppi-disable: Add regcomp.c, regex_internal.c, regex_internal.h, stat-time.h. * argmatch.h: Include verify.h (ARGMATCH_VERIFY): Use verify rather than rolling our own. (ARGMATCH_ASSERT): Remove; unused. * canonicalize.c: Assume STDC_HEADERS. * exclude.c: Include "strcase.h". * regex_internal.h [!defined _LIBC]: Likewise. * getusershell.c: Include stdio--.h rather than stdio.h and stdio-safer.h. (getusershell): Call fopen, not fopen_safer. * save-cwd.c: Include fcntl--.h rather than fcntl.h. Do not include unistd-safer.h. (save_cwd): Don't call fd_safer; no longer needed now that we include fcntl--.h. * modules/argmatch (Depends-on): Add verify. * modules/getloadavg (Depends-on): Depend on fcntl-safer, not unistd-safer. * modules/save-cwd (Depends-on): Likewise. * backupfile.m4, calloc.m4, chown.m4, cloexec.m4, dup2.m4: * fileblocks.m4, free.m4, ftruncate.m4, getcwd.m4, getpagesize.m4: * getugroups.m4, group-member.m4, idcache.m4, link-follow.m4: * mkstemp.m4, mktime.m4, mountlist.m4, nanosleep.m4, pathmax.m4: * physmem.m4, posixver.m4, putenv.m4, safe-read.m4, same.m4: * save-cwd.m4, stdio-safer.m4, unistd-safer.m4, unlinkdir.m4: * userspec.m4, xgetcwd.m4, xreadlink.m4: Don't bother checking for string.h, stdlib.h, unistd.h. * fts.m4 (gl_FUNC_FTS_CORE): Don't require AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK; that's now the lstat module's job. * jm-macros.m4 (gl_MACROS): Likewise. * prereq.m4 (gl_PREREQ): Add gl_FUNC_LSTAT. * backupfile.c: Use ARGMATCH_VERIFY, just in case. * posixtm.c (posixtime) [lint]: Initialize *all* of tm0, not just the .tm_year member, since otherwise gcc-4.0 would now warn about tm_zone, tm_gmtoff, tm_isdst, tm_yday, tm_wday. * quotearg.c (quotearg_n_options): Change code to be suboptimal, in order to avoid an unsuppressible warning from gcc on 64-bit systems. * lstat.m4 (gl_FUNC_LSTAT): Use AC_LIBSOURCES to require lstat.c and lstat.h. Remove obsolete comment. * xreadlink.m4: Use AC_LIBSOURCES and AC_LIBOBJ. * xstrtod.m4: Likewise.
Derek R. Price 1e3866b6 2005-09-16T00:23:36 * regcomp.c, regexec.c, regex_internal.c: Back out previous changes, consolidating in... * regex_internal.h: ...this file.

Paul Eggert c4f640f1 2005-09-06T07:36:48 Change bitset word type from unsigned int to unsigned long int, as this has better performance on typical 64-bit hosts. Port bitset code to hosts with unusual word sizes. * lib/regcomp.c (build_equiv_class, build_charclass): (build_range_exp, build_collating_symbol): Prefer bitset to re_bitset_ptr_t in prototypes, when the actual argument is a bitset. This is merely a style issue, but it makes it clearer that an entire array is expected. (re_compile_fastmap_iter, init_dfa, init_word_char, optimize_subexps): * lib/regcomp.c (lower_subexp, parse_bracket_exp): (built_charclass_op): Port to the case where bitset_word is not the same as unsigned int. * lib/regex_internal.h (bitset_set, bitset_clear, bitset_contain): (bitset_not, bitset_merge, bitset_set_all, bitset_mask): Likewise. * lib/regexec.c (check_dst_limits_calc_pos_1): (check_subexp_matching_top): (build_trtable, group_nodes_into_DFAstates): Likewise. * lib/regcomp.c (re_compile_fastmap_iter, utf8_sb_map): (optimize_utf8): Don't assume that SBC_MAX is a multiple of BITSET_WORD_BITS. * lib/regex_internal.h (bitset_set_all, bitset_not): Likewise. * lib/regexec.c (group_nodes_into_DFAstates): Likewise. * lib/regcomp.c (utf8_sb_map): Don't assume UINT_MAX == 0xffffffff. * lib/regcomp.c (optimize_subexps, lower_subexp): Work even if bitset_word has holes in its bitwise representation. * lib/regex_internal.h (BITSET_WORD_BITS): Likewise. * lib/regexec.c (check_dst_limits_calc_pos_1): (heck_subexp_matching_top): Likewise. * lib/regex_internal.c (re_string_reconstruct): Don't assume UCHAR_MAX == 255. * lib/regex_internal.h (bitset_set_all): Likewise. * lib/regex_internal.h (BITSET_WORD_BITS): Renamed from UINT_BITS.

All callers changed. * lib/regexec.c (build_trtable): Don't assume bitset has no stricter alignment than re_node_set; do this by defining a new internal type struct dests_alloc and using it to allocate memory. * config/srclist.txt: Add glibc bug 1302.
Paul Eggert 812cbebe 2005-09-02T22:54:59 Check for arithmetic overflow when calculating sizes, to prevent some buffer-overflow issues. These patches are conservative, in the sense that when I couldn't determine whether an overflow was possible, I inserted a run-time check. * regex_internal.h (re_xmalloc, re_xrealloc, re_x2realloc): New macros. (SIZE_MAX) [!defined SIZE_MAX]: New macro. (re_alloc_oversized, re_x2alloc_oversized, re_xnmalloc): (re_xnrealloc, re_x2nrealloc): New inline functions. * lib/regcomp.c (init_dfa, analyze, build_range_exp, parse_bracket_exp): (build_equiv_class, build_charclass): Check for arithmetic overflow in size expression calculations. * lib/regex_internal.c (re_string_realloc_buffers): (build_wcs_upper_buffer, re_node_set_add_intersect): (re_node_set_init_union, re_node_set_insert, re_node_set_insert_last): (re_dfa_add_node, register_state): Likewise. * lib/regexec.c (re_search_stub, re_copy_regs, re_search_internal): (prune_impossible_nodes, push_fail_stack, set_regs, check_arrival): (build_trtable, extend_buffers, match_ctx_init, match_ctx_add_entry): (match_ctx_add_subtop, match_ctx_add_sublast): Likewise.

All callers changed. * lib/regexec.c (check_halt_node_context, check_dst_limits): (build_trtable, check_node_accept): Likewise. * lib/regex_internal.h: Include stdbool.h. Fix bugs uncovered when converting to bool. * lib/regcomp.c (calc_eclosure_iter): Check for storage allocation failure instead of charging ahead blindly. * lib/regex_internal.c (register_state): Likewise. * lib/regexec.c (re_search_2_stub): Use simpler method than boolean for freeing internal storage. (group_nodes_into_DFA_states): Use unsigned int, not int, for bitset pieces used as boolean, to avoid undefined behavior on hosts that do int overflow checking. * config/srclist.txt: Add glibc bug 1285.
Paul Eggert 28492cce 2005-08-31T22:51:09 On 64-bit hosts (where size_t is 64 bits and int is 32 bits), the old glibc regex code mishandles strings longer than 2**31 bytes. This patch fixes this when the regex code is used in gnulib (i.e., outside glibc). * lib/regex.h (_REGEX_LARGE_OFFSETS): New feature-test macro, governing whether the rest of this patch is active.

All uses changed to the standard name CHAR_BIT. * lib/regexec.c (match_ctx_add_entry): Don't assume that ~0 == -1; this is not true on one's complement and signed-magnitude hosts.
Paul Eggert af36f47f 2005-08-31T18:08:34 * lib/regex_internal.h (re_sub_match_top_t): Remove unused member next_last_offset. (struct re_dfa_t): Remove unused member states_alloc. * lib/regcomp.c (init_dfa): Don't initialize unused members. * config/srclist.txt: Add glibc bug 1273.
Paul Eggert 3af956ae 2005-08-26T21:47:51 * config/srclist.text: Add glibc bug 1248. * lib/regex_internal.h: Remove all references to RE_NO_INTERNAL_PROTOTYPES; no longer neeeded now that we assume C89 or better. (bitset_not, bitset_merge, bitset_not_merge): (bitset_mask, re_string_allocate, re_string_construct): (re_string_reconstruct, re_string_destruct, re_string_elem_size_at): (re_string_char_size_at, re_string_wchar_at, re_string_peek_byte_case): (re_string_fetch_byte_case, re_node_set_alloc, re_node_set_init_1): (re_node_set_init_2, re_node_set_init_copy, re_node_set_add_intersect): (re_node_set_init_union, re_node_set_merge, re_node_set_insert): (re_node_set_insert_last, re_node_set_compare, re_node_set_contains): (re_node_set_remove_at, re_dfa_add_node, re_acquire_state): (re_acquire_state_context): Remove unnecessary forward decls. (re_string_char_size_at, re_string_wchar_at, re_string_elem_size_at): Put __attribute at function definition, now that the function decl has been removed. * lib/regex_internal.c (re_string_peek_byte_case): (re_string_fetch_byte_case, re_node_set_compare, re_node_set_contains): Likewise.
Paul Eggert 8579e671 2005-08-26T06:08:46 Fix typo: __LIBC -> _LIBC.
Paul Eggert f58f44a2 2005-08-26T05:58:54 * config/srclist.txt: Add glibc bug 1245. * lib/regexec.c (set_regs): Don't alloca with an unbounded size. alloca modernization/simplification for regex. * lib/regex.c: Remove portability cruft for alloca. This no longer needs to be at the start of the file, and can be moved into regex_internal.h and simplified. * lib/regex_internal.h: Include <alloca.h>. (__libc_use_alloca) [!defined _LIBC]: New macro. * lib/regexec.c (build_trtable): Remove "#ifdef _LIBC", since the code now works outside glibc.
Paul Eggert cad71bd9 2005-08-25T20:39:57 Make regex safe for g++. This fixes one real bug (an "err" that should have been "*err"). * config/srclist.txt: Add glibc bug 1241. * lib/regex_internal.h (re_calloc): New macro, consistent with re_malloc etc. All callers of calloc changed to use re_calloc. * lib/regex_internal.c (build_wcs_upper_buffer): Return reg_errcode_t, not int. All callers changed. * lib/regcomp.c (re_compile_fastmap_iter): Don't use alloca (mb_cur_max); just use an array of size MB_LEN_MAX. * lib/regexec.c (push_fail_stack): Use re_realloc, not realloc. (find_recover_state): Change "err" to "*err"; this fixes what appears to be a real bug. (check_arrival_expand_ecl_sub): Be consistent about reg_errcode_t versus int.
Paul Eggert e6d7b6da 2005-08-24T23:29:39 * config/srclist.txt: Add glibc bug 1237. * lib/regcomp.c, lib/regex_internal.c, lib/regex_internal.h: * lib/regexec.c: All uses of recently-renamed identifiers changed to use the new, POSIX-compliant names. The code will build and run just fine without these changes, but it's better to eat our own dog food and use the standard-conforming names. * m4/regex.m4 (gl_REGEX): Use POSIX-compliant spellings when testing for GNU regex features.
Paul Eggert 087e9e5b 2005-08-20T07:42:15 * config/srclist.txt: Add glibc bugs 1220, 1221, 1222. * lib/regcomp.c: (re_compile_pattern, re_set_syntax, re_compile_fastmap): (re_compile_fastmap_iter, regcomp, regerror, regfree): (re_compile_internal, init_dfa, init_word_char, free_workarea_compile): (create_initial_state, optimize_utf8, analyze, postorder, preorder): (optimize_subexps, lower_subexps, lower_subexp, calc_first, calc_next): (link_nfa_nodes, duplicate_node_closure, search_duplicated_node): (duplicate_node, calc_inveclosure, calc_eclosure, calc_eclosure_iter): (fetch_token, peek_token, peek_token_bracket, parse, parse_reg_exp): (parse_branch, parse_expression, parse_sub_exp, parse_dup_op): (build_range_exp, build_collating_symbol, parse_bracket_exp): (parse_bracket_element, parse_bracket_symbol, build_equiv_class): (build_charclass, build_charclass_op, fetch_number, create_tree): (create_token_tree, mark_opt_subexp, duplicate_tree): Use prototypes rather than old-style definitions. * lib/regex_internal.c: (re_string_allocate, re_string_construct, re_string_realloc_buffers): (re_string_construct_common, build_wcs_buffer, build_wcs_upper_buffer): (re_string_skip_chars, build_upper_buffer, re_string_translate_buffer): (re_string_reconstruct, re_string_peek_byte_case): (re_string_fetch_byte_case, re_string_destruct, re_string_context_at): (re_node_set_alloc, re_node_set_init_1, re_node_set_init_2): (re_node_set_init_copy, re_node_set_add_intersect): (re_node_set_init_union, re_node_set_merge, re_node_set_insert): (re_node_set_insert_last, re_node_set_compare, re_node_set_contains): (re_node_set_remove_at, re_dfa_add_node, calc_state_hash): (re_acquire_state, re_acquire_state_context, register_state): (create_ci_newstate, create_cd_newstate, free_state): Likewise. * lib/regexec.c (regexec, re_match, re_search, re_match_2, re_search_2): (re_search_2_stub, re_search_stub, re_copy_regs, re_set_registers): (re_search_internal, prune_impossible_nodes): (acquire_init_state_context, check_matching, static): (check_halt_node_context, check_halt_state_context, proceed_next_node): (push_fail_stack, pop_fail_stack, set_regs, free_fail_stack_return): (update_regs, sift_states_backward, build_sifted_states): (clean_state_log_if_needed, merge_state_array): (update_cur_sifted_state, add_epsilon_src_nodes): (sub_epsilon_src_nodes, check_dst_limits, check_dst_limits_calc_pos_1): (check_dst_limits_calc_pos, check_subexp_limits, sift_states_bkref): (sift_states_iter_mb, transit_state, merge_state_with_log, static): (find_recover_state, check_subexp_matching_top, transit_state_mb): (transit_state_bkref, get_subexp, get_subexp_sub, find_subexp_node): (check_arrival, check_arrival_add_next_nodes): (check_arrival_expand_ecl, check_arrival_expand_ecl_sub): (expand_bkref_cache, build_trtable, group_nodes_into_DFAstates): (check_node_accept_bytes, check_node_accept, extend_buffers): (match_ctx_init, match_ctx_clean, match_ctx_free, match_ctx_add_entry): (search_cur_bkref_entry, match_ctx_add_subtop, match_ctx_add_sublast): (sift_ctx_init): Likewise. * lib/regex_internal.h: (re_string_allocate, re_string_construct, re_string_reconstruct): (re_string_realloc_buffers, build_wcs_buffer, build_wcs_upper_buffer): (build_upper_buffer, re_string_translate_buffer, re_string_destruct): (re_string_elem_size_at, re_string_char_size_at, re_string_wchar_at): (re_string_context_at, re_string_peek_byte_case): (re_string_fetch_byte_case): Declare even if RE_NO_INTERNAL_PROTOTYPES is defined, since we now use prototypes always. * lib/regex.h (_RE_ARGS): Remove. No longer needed, since we assume C89 or better. All uses removed.
Paul Eggert 151e40bb 2005-07-07T08:08:39 * modules/regex (Files): Add lib/regex_internal.c, lib/regex_internal.h, lib/regexec.c, lib/regcomp.c, m4/codeset.m4. (Depends-on): Add extensions. (Makefile.am): Remove lib_SOURCES; now done by m4 code. * config/srclist.txt: Add regcomp.c, regex.c, regex.h, regex_internal.c, regexec.c. Add regex_internal.h too, but as a comment, since the libc version is currently broken in gnulib mode. * lib/regex.c, lib/regex.h: Sync from libc. * lib/regcomp.c, lib/regexec_internal.c, lib/regex_internal.h, lib/regexec.c: New files, synced from libc, except that regex_internal.h currently has a small porting fix. * m4/regex.m4: Adjust to new libc regex implementation. (gl_INCLUDED_REGEX): Add AC_LIBSOURCES for all the .c and .h parts of (the new) regex. Quote the m4 stuff better. Check for RE_ICASE bug of old gnulib. Check for REG_STARTEND of recent libc. Rename local variables from jm_* to gl_*. Quote operand of "test -f". Say "recent enough" version of libc, not "version 2". (gl_PREREQ_REGEX): Remove AC_FUNC_ALLOCA, since alloca is a prerequisite module. Remove AC_HEADER_STDC; no longer needed. Check for locale.h, isblank, mbrtowc, wcrtomb, wcscoll. Remove check for btowc, isascii. Require AM_LANGINFO_CODESET.
