Just sending this because I'd like the copy in pu updated. Changes noted below: Ævar Arnfjörð Bjarmason (19): grep: amend submodule recursion test in preparation for rx engine testing grep: add tests for grep pattern types being passed to submodules A s/PCRE/LIBPCRE/ on the test_have_prereq, now makes sense with the series in sequence (error added during rebasing). grep: submodule-related case statements should die if new fields are added grep: remove redundant regflags assignment under PCRE grep: remove redundant `regflags &= ~REG_EXTENDED` assignments NEW: Similarly to how we didn't need to set regflags under PCRE, we were negating REG_EXTENDED under POSIX basic, without ever setting it in the first place. This was just as confusing as the PCRE oddity, so remove it. Makefile & configure: reword outdated comment about PCRE grep: add a test for backreferences in PCRE patterns log: add exhaustive tests for pattern style options & config log: add -P as a synonym for --perl-regexp grep & rev-list doc: stop promising libpcre for --perl-regexp grep: make grep.patternType=[pcre|pcre1] a synonym for "perl" test-lib: rename the LIBPCRE prerequisite to PCRE One corresponding s/LIBPCRE/PCRE/ for the earlier change, see above. grep: change the internal PCRE macro names to be PCRE1 grep: change the internal PCRE code & header names to be PCRE1 perf: add a performance comparison test of grep -E and -P grep: add support for the PCRE v1 JIT API grep: add support for PCRE v2 We now give proper error messages via pcre2_get_error_message() when pcre2_match() fails with errors other than "didn't match", the common case for this is that the engine gave up on a pathological pattern / input combination. grep: remove support for concurrent use of both PCRE v1 & v2 Makefile & configure: make PCRE v2 the default PCRE implementation Added more details to the commit message about why switching to PCRE v2 by default is a good idea. I hadn't noticed before that deep bugs in PCRE v1 are being WONTFIX'd on the bugtracker saying "nope, never fixing thath in v1, switch to v2".
