* (regexp-tests-backtrack-optimization): Mark it as failingStefan Monnier2023-09-051-0/+1
| | | | | * test/src/regex-emacs-tests.el (regexp-tests-backtrack-optimization): The fix for bug#65726 broke some of the optimization added for bug#61514.
* ; Add regression test for bug#65726Mattias Engdegård2023-09-051-0/+4
| | | | | * test/src/regex-emacs-tests.el (regex-tests-mutual-exclusive-inf-rec): New test.
* regex-emacs.c: Reduce the use of backtracking a bit furtherStefan Monnier2023-02-201-0/+11
| | | | | | | | | | | bug#61514 exhibited some undesirable backtracking in a case where it's easy to avoid it by making `mutually_exclusive_p` just a bit more careful. * src/regex-emacs.c (mutually_exclusive_p): Handle `on_failure_jump`s. * test/src/regex-emacs-tests.el (regexp-tests-backtrack-optimization): Add a few tests.

* Fix regexp matching with atomic strings and optimised backtrackingMattias Engdegård2022-10-241-0/+5
| | | | | | | | | | | | | | | | This bug occurs when an atomic pattern is matched at the end of a string and the on-failure-keep-string-jump optimisation is in effect, as in: (string-match "\\'\\(?:ab\\)*\\'" "a") which succeeded but clearly should not (bug#58726). Reported by Michael Heerdegen. * src/regex-emacs.c (PREFETCH): Add reset parameter. (re_match_2_internal): Use it for proper atomic pattern treatment. * test/src/regex-emacs-tests.el (regexp-atomic-failure): New test.
* Audit quoting the quote character in doc stringsLars Ingebrigtsen2022-04-221-6/+6

* Recognise ß properly as a lower-case letter (bug#11309)Mattias Engdegård2020-12-091-4/+11
| | | | | | | | | | | | | | ß was incorrectly treated as a caseless character and thus not matched by the regexp [[:lower:]] (or, in case-folding mode, [[:upper:]]). The reason is that the upcase table maps it to itself, which can be remedied by mapping it to ẞ (U+7838) instead. Doing so does not affect upcasing since the special-uppercase property maps it to SS. * lisp/international/characters.el (tbl): Map ß to ẞ in the upcase table. * test/src/regex-emacs-tests.el (regexp-eszett): Uncomment previously failing tests. Add checks to make sure that case transformations remain valid.
* Fix [:upper:] and [:lower:] for Unicode characters (bug#11309)Mattias Engdegård2020-12-091-0/+57
| | | | | | | | * src/regex-emacs.c (execute_charset): Add canon_table argument to allow expression of a correct predicate for [:upper:] and [:lower:]. (mutually_exclusive_p, re_match_2_internal): Pass extra argument. * test/src/regex-emacs-tests.el (regexp-case-fold, regexp-eszett): New tests. Parts of regexp-eszett still fail and are commented out.
