New submission from Tim Peters <t...@python.org>:
I added some excruciatingly obscure technical tricks to ensure that fnmatch.py's regexps can't fall into exponential-time match failures. It's hard to stop re from useless backtracking. But the new "atomic groups" make that easy instead in some cases, and make it trivial in the cases fnmatch needs. Of course addressing this has to wait for the atomic groups PR to get merged GH-31982) ---------- assignee: tim.peters components: Library (Lib) messages: 415662 nosy: tim.peters priority: normal severity: normal stage: needs patch status: open title: Use atomic groups to simplify fnmatch type: behavior versions: Python 3.11 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue47080> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
