* regex: modernize to newer regex bugsetPaul Eggert2021-07-141-5/+6
| | | | | | | | | | | Problem reported by Hiroo Hayashi in: https://lists.gnu.org/r/bug-gnulib/2021-07/msg00024.html * m4/regex.m4 (gl_REGEX): Allow newer glibc behavior for ()0|\1, behavior where the regex compiles but does not match. Test for glibc bug 11053. * tests/test-regex.c (bug_regex11, main): Add casts needed for printf portability. (main): Allow newer glibc behavior for ()0|\1.
* regex-tests: test for regressions fixed by the previous commitDmitry V. Levin2021-06-061-0/+4
| | | | | | | * tests/test-regex.c (tests): Add test cases for *+ and ** regressions fixed by the previous commit. Link: https://lists.gnu.org/archive/html/bug-gnulib/2021-04/msg00134.html
* regex-tests: remove incorrect commentDmitry V. Levin2021-06-061-1/+0
| | | | | | | | * tests/test-regex.c (tests): Remove the comment saying that some tests are not used. That comment was copied along with tests from glibc where some of these tests are commented out. Fixes: 70b673eb7 ("regex: fix longstanding backref match bug")
* regex-tests: add bug 11053 testPaul Eggert2021-02-051-0/+29
| | | | * tests/test-regex.c (main): New test case for glibc bug 11053.
* regex: fix longstanding backref match bugPaul Eggert2021-02-051-2/+111
| | | | | | | | | | | | | | This fixes a longstanding glibc bug concerning backreferences <https://sourceware.org/11053> (2009-12-04). * lib/regexec.c (proceed_next_node, push_fail_stack) (pop_fail_stack): Push and pop the previous registers as well as the current ones. All callers changed. (set_regs): Also pop if CUR_NODE has already been checked, so that it does not get added as a duplicate set entry. (update_regs): Fix comment location. * tests/test-regex.c (tests): New constant. (bug_regex11): New test function. (main): Bump alarm value. Call new test function.
* regex-tests: fix typoPaul Eggert2021-02-051-1/+2
| | | | | * tests/test-regex.c (main): Fix typo that would have caused an old test case to report incorrect values on failure.

* regex-tests: tweak to avoid a clang-10 warningJim Meyering2020-12-291-1/+1
| | | | | | | | | * tests/test-regex.c: Compare with explicit zero, rather than as boolean to avoid this from clang-10: test-regex.c:315:9: error: converting the result of '<<' to a \ boolean always evaluates to true \ [-Werror,-Wtautological-constant-compare] if (! REG_STARTEND)
* regex-tests: Make test more robust.Bruno Haible2020-09-261-26/+34
| | | | | * tests/test-regex.c (main): Make sure to revert the locale to "C" after the test in "tr_TR.UTF-8" locale. Exit if we can't revert it.
* regex-tests: fix possible Turkish false-alarmPaul Eggert2020-09-251-1/+3
| | | | | | | * modules/regex-tests (Depends-on): Add wctype-h. * tests/test-regex.c: Include wctype.h. (main): Check that ‘i’ uppercases to ‘İ’ in Turkish, as the Turkish regex test assumes this.
* regex-tests: fix test and add debug outputPaul Eggert2020-09-251-46/+86
| | | | | | | | | | | | | Perhaps this will fix the recent grep test failure reported at: https://buildfarm.opencsw.org/buildbot/builders/ggrep-solaris10-sparc/builds/199 At least, the debug output should help narrow down the failure. * tests/test-regex.c: Include stdarg.h, stdio.h. (exit_status): New var. (report_error): New function. (main): Use it to report failures to stdout instead of merely exiting with some nonzero status. The status info alone isn’t enough to do remote debugging. In the new tr_TR.UTF-8 test, clear regex before calling re_compile_pattern, fixing a portability bug.
* regex: fix ignore-case Turkish bugPaul Eggert2020-09-231-5/+36
| | | | | | | | * 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-tests, regex: allow glibc re_search behaviorDmitry V. Levin2013-04-111-6/+17
| | | | | | | | | | | | | | | | | | | | The data passed to re_search by the test for glibc bug 15078 is a multi-character collating element followed by a single character. According to POSIX, "It is unspecified whether a non-matching list expression matches a multi-character collating element that is not matched by any of the expressions." One of differences between glibc and gnulib implementations of re_search is that glibc re_search matches multi-character collating elements in that case while gnulib re_search doesn't. Since both re_search implementations conform to standard, change the test to allow glibc re_search behavior. * tests/test-regex.c (main): In test for glibc bug 15078, reformat re_search input data to make the multi-character collating element in it clearly visible, and treat re_search return code 0 as valid. * m4/regex.m4 (gl_REGEX): Likewise.
* regex-tests: skip UTF-8 test on mingwEric Blake2013-03-121-19/+26
| | | | | | | | | | | | | test-regex failed on mingw; and I traced it in gdb to an instance of init_dfa() setting dfa->is_utf8 to 0 in spite of setlocale() claiming success for "en_US.UTF-8". test-wcwidth already has precedent for skipping utf-8 tests where the system (or gnulib setlocale replacement, in this case) lies about utf-8 support. * modules/regex-tests (Depends-on): Add localcharset. * tests/test-regex.c (main): Use it to skip test on mingw.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | On mingw (at least, when cross-compiling with Fedora 18's mingw32-headers-2.0.999-0.15.trunk.20121110.fc18.noarch build), compilation of test-regex fails: test-regex.c: In function 'main': test-regex.c:42:11: error: 'SIGALRM' undeclared (first use in this function) test-regex.c:42:11: note: each undeclared identifier is reported only once for each function it appears in test-regex.c:43:3: warning: implicit declaration of function 'alarm' It turns out that recent mingw64 added an export of alarm() and SIGALRM, but guarded their declarations behind __USE_MINGW_ALARM (default off, and with alarm() only in the non-standard <io.h>); so the m4 tests were setting HAVE_ALARM to 1 based on link success but then failing to compile. * doc/posix-functions/alarm.texi (alarm): Document that alarm exists but still doesn't work in newer mingw. * m4/frexp.m4 (gl_FUNC_FREXP_WORKS): Check for alarm declaration, not existence.
