eb04c21373
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.

# PCRE version 4.4 21-August-2003

|
|
# Tests taken from PCRE and modified to suit glibc regex.

# PCRE LICENCE
|
|
# ------------
|
|
#
|
|
# PCRE is a library of functions to support regular expressions whose syntax
|
|
# and semantics are as close as possible to those of the Perl 5 language.
