* regex: __builtin_expect → __glibc_unlikelyPaul Eggert2018-10-141-73/+79
| | | | | | | | | | | | | [BZ#23744] This refactoring was prompted by a problem when the regex code is used as part of Gnulib and when the builder’s compiler does not grok __builtin_expect. Problem reported for Gawk by Nelson H.F. Beebe in: https://lists.gnu.org/r/bug-gnulib/2018-09/msg00137.html Although this refactoring does not fix the problem directly, we might as well have Gawk use the now-preferred glibc style for when __builtin_expect is unavailable. * posix/regex_internal.h (BE): Remove. All uses replaced by __glibc_unlikely or __glibc_likely.
* regex: fix uninitialized memory accessPaul Eggert2018-08-251-2/+2
| | | | | | | | | | | | | I introduced this bug into gnulib in commit 8335a4d6c7b4448cd0bcb6d0bebf1d456bcfdb17 dated 2006-04-10; eventually it was merged into glibc. The bug was found by project-repo <bugs@feusi.co> and reported here: https://lists.gnu.org/r/sed-devel/2018-08/msg00017.html Diagnosis and draft fix reported by Assaf Gordon here: https://lists.gnu.org/r/bug-gnulib/2018-08/msg00071.html https://lists.gnu.org/r/bug-gnulib/2018-08/msg00142.html * posix/regex_internal.c (build_wcs_upper_buffer): Fix bug when mbrtowc returns 0.
* posix: Sync gnulib regex implementationAdhemerval Zanella2018-07-041-138/+157
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch syncs the regex implementation with gnulib (commit 0ee5212). Only two changes in GLIBC regex testing are required: 1. posix/bug-regex28.c: as previously discussed [1] the change of expected results on the pattern should be safe. 2. posix/PCRE.tests: the ERE (a)|\1 is malformed (in the sense that the \1 doesn't mean anything) and although current GLIBC accepts it has undefined behavior. This patch removes the specific test. This sync contains some patches from thread 'Regex: Make libc regex more usable outside GLIBC.' [2] which have been pushed upstream in gnulib. This patches also fixes some regex issues (BZ #23233, BZ #21163, BZ #18986, BZ #13762) and I did not add testcases for both #23233 and #13762 because I couldn't think a simple way to trigger the expected failure path to trigger them. Checked on x86_64-linux-gnu and i686-linux-gnu. [BZ #23233] [BZ #21163] [BZ #18986] [BZ #13762] * posix/Makefile (tests): Add bug-regex37 and bug-regex38. * posix/PCRE.tests: Remove invalid test. * posix/bug-regex28.c: Fix expected values for used syntax. * posix/bug-regex37.c: New file. * posix/bug-regex38.c: Likewise. * posix/regcomp.c: Sync with gnulib. * posix/regex.c: Likewise. * posix/regex.h: Likewise. * posix/regex_internal.c: Likewise. * posix/regex_internal.h: Likewise. * posix/regexec.c: Likewise.

* Fix regex wcrtomb namespace (bug 18496).Joseph Myers2015-06-051-2/+2
| | | | | | | | | | | | | | The regex code brings in references to wcrtomb, which isn't in all the standards that contain regex. This patch makes it call __wcrtomb instead (in fact some places already called __wcrtomb, so this patch makes it internally consistent about which name is used). Tested for x86_64 and x86 that installed stripped shared libraries are unchanged by the patch. [BZ #18496] * posix/regex_internal.c (build_wcs_upper_buffer): Call __wcrtomb instead of wcrtomb.
* Fix regex wctype namespace (bug 18495).Joseph Myers2015-06-051-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | regcomp brings in references to various wctype functions that aren't in all the standards including regcomp. This patch fixes this in the usual way by using the __* versions of these functions (which already exist, but some didn't have libc_hidden_proto / libc_hidden_def before). Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). (Other wide character function references from the regex code mean that this patch by itself doesn't fix any XFAILed linknamespace test failures; further patches will be needed for that.)

* Fix up regcomp/regexecJakub Jelinek2011-12-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | 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; }

Avoided recursion on the (very unbalanced) parse tree. [BZ #611] * posix/regcomp.c (struct subexp_optimize, analyze_tree, calc_epsdest, re_dfa_add_tree_node, mark_opt_subexp_iter): Removed.
