* regex: make it closer to libcPaul Eggert2016-02-191-33/+32
| | | | | | | | | | | | | | | 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.

* Diagnose ERE '()|\1'Paul Eggert2015-09-191-0/+4
| | | | | | | | | Problem reported by Hanno Böck in: http://bugs.gnu.org/21513 * lib/regcomp.c (parse_reg_exp): While parsing alternatives, keep track of the set of previously-completed subexpressions available before the first alternative, and restore this set just before parsing each subsequent alternative. This lets us diagnose the invalid back-reference in the ERE '()|\1'.

* regex: don't deref NULL upon heap allocation failureJim Meyering2014-07-121-0/+2
| | | | | | | | | | | * lib/regcomp.c (parse_dup_op): Handle duplicate_tree failure in one more place. To trigger the segfault, configure grep -with-included-regex, build it, and run these commands: ( ulimit -v 300000; echo a|src/grep -E a+++++++++++++++++++++ ) I discovered this while replying to a private report from Jens Schleusener about excessive memory consumption by grep when using a regular expression like the one above.

* c-ctype, regex, verify: port to gcc -std=c90 -pedanticPaul Eggert2013-05-291-1/+1
| | | | | | | | | | | | Avoid constructions that are rejected by gcc -std=c90 -pedantic. This fixes a porting bug I recently reintroduced in regex, and some other instances that I discovered while testing the fix. * lib/c-ctype.h [__STRICT_ANSI__]: Avoid ({ ... }). * lib/regcomp.c (utf8_sb_map) [__STRICT_ANSI__]: Avoid [0 ... N] = E. * lib/regex_internal.h [!_LIBC && GNULIB_LOCK]: Do not use a macro with an empty argument if this is a pedantic pre-C99 GCC. * lib/verify.h: Do not use _Static_assert if this is a pedantic pre-C11 GCC.
* regex: fix dfa race in multithreaded usesPaul Eggert2013-05-191-3/+8
| | | | | | | | | | | | | | | | | | | | 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. (regfree, re_compile_internal): Destroy the lock. (re_compile_internal): Check for lock-initialization failure.
* regex: rename remaining __attribute calls to __attribute__.Gary V. Vaughan2013-03-081-5/+5
| | | | | | | | | | | | | | | Commit 930b85b changed definition of __attribute, but left some uses unchanged, preventing compilation of regex module on most non-gcc environments: * lib/regcomp.c (re_set_fastmap, seek_collating_symbol_entry) (lookup_collation_sequence_value, build_range_exp) (build_collating_symbol): Set attributes with newly renamed __attribute__ decorator. * lib/regex_internal.c (re_string_peek_byte_case) (re_node_set_compare, re_node_set_contains): Likewise. * lib/regexec.c (acquire_init_state_context): Likewise.

| | | | | | | | | | | | | 2013-02-26 Siddhesh Poyarekar <siddhesh@redhat.com> * lib/regex_internal.h (__attribute__): Rename from __attribute. All uses changed. (bitset_not, bitset_merge, bitset_mask, re_string_char_size_at) (re_string_wchar_at, re_string_elem_size_at): Mark function as possibly unused. 2013-02-12 Andreas Schwab <schwab@suse.de> [BZ #11561] * lib/regcomp.c (parse_bracket_exp) [_LIBC]: When looking up collating elements compare against the byte sequence of it, not its name.
* regex: conform to strict CPaul Eggert2013-01-051-1/+2
| | | | | * lib/regcomp.c (parse_bracket_exp): Add cast to conform to strict C. From Aharon Robbins.
* regex: omit needless signed-pointer castsPaul Eggert2013-01-011-13/+13
| | | | | | | | | * lib/regcomp.c (build_charclass, build_charclass_op): Use char *, not unsigned char *, for class name and extra. The char values are always nonnegative so there's no need to insist on unsigned char * here, and using char * removes the need for casts. Reported by Aharon Robbins in <http://sourceware.org/ml/libc-alpha/2012-12/msg00456.html>.

| | | | | | Reported by Aharon Robbins in <http://sourceware.org/ml/libc-alpha/2012-12/msg00456.html>. * lib/regcomp.c (init_word_char): Declaration before statement.
* 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: use locale-independent comparison for codeset namePaul Eggert2012-06-261-2/+4
| | | | | | | | | 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.
* regex: avoid warning when pointers are not longPaul Eggert2012-06-171-2/+5
| | | | | | | | | * lib/regcomp.c (parse_dup_op, mark_opt_subexp): Cast between void * and uintptr_t, not long, for portability to hosts where pointers and long have different sizes. Issue noted by Daniel P. Berrange in <http://lists.gnu.org/archive/html/bug-gnulib/2012-06/msg00122.html> and fix suggested by Bruno Haible in <http://lists.gnu.org/archive/html/bug-gnulib/2012-06/msg00128.html>.
* regex: don't assume uint64_t or uint32_tPaul Eggert2012-05-261-6/+10
| | | | | | | | * lib/regcomp.c (init_word_char): Don't assume that the types uint64_t and uint32_t exist. The C standard doesn't guarantee them, and on some 32-bit compilers there is no uint64_t. Problem reported by Gianluigi Tiesi in <http://lists.gnu.org/archive/html/bug-gnulib/2012-03/msg00154.html>.
* regex: remove unnecessary type punningPaul Eggert2012-04-041-13/+13
| | | | | | | | | | | | | | Problem reported by Vladimir Serbinenko in <http://lists.gnu.org/archive/html/bug-gnulib/2012-04/msg00006.html>. * lib/regex.h (struct re_pattern_buffer): Change the type of __REPB_PREFIX(buffer) from unsigned char * to struct re_dfa_t *. Fix comment to match code. * lib/regcomp.c (re_compile_fastmap, re_compile_fastmap_iter, regfree) (re_compile_internal, free_workarea_compile, analyze, lower_subexp) (parse, parse_reg_exp, parse_branch, parse_expression, parse_sub_exp): * lib/regexec.c (regexec, re_search_stub, re_search_internal) (set_regs): Omit no-longer-necessary casts.
* regex: pacify GCC when compiling GRUBPaul Eggert2012-03-301-1/+1
| | | | | | * lib/regcomp.c (init_dfa): Make a pointer 'const', to avoid a diagnostic. Reported by Vladimir Serbinenko in <http://lists.gnu.org/archive/html/bug-gnulib/2012-03/msg00163.html>.
* regex: diagnose too-large repeat counts in EREsPaul Eggert2012-03-161-2/+10
| | | | | | | | | | | | | | Previously, the code did not diagnose the too-large repeat count in EREs like 'b{1000000000}'; instead, it silently treated the ERE as if it were 'b\{1000000000}', which is unexpected. * lib/regcomp.c (parse_dup_op): Fail with REG_ESIZE if a repeat count is too large. REG_ESIZE is used nowhere else, and the diagnostic is a reasonable one for this problem. Another option would be to create a new REG_OVERFLOW error for repeat counts that are too large.

(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.

* regcomp.c: make non-_LIBC implementation of build_range_exp consistentJim Meyering2010-03-201-7/+15
| | | | | | | | | | | | The _LIBC implementation of build_range_exp correctly honors the RE_NO_EMPTY_RANGES flag when checking for reversed range endpoints. However, the non-_LIBC implementation would ignore that syntax-bit flag and return REG_ERANGE unconditionally. This change makes it honor that flag. * lib/regcomp.c (build_range_exp) [!_LIBC]: Add a parameter: "syntax". Make two pointer parameters "const". Use "syntax" bits in order to honor RE_NO_EMPTY_RANGES. (parse_bracket_exp): Update caller.
