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) |
