Nit: (and not necessarily one that needs to be addressed directly) -- do you mean "backtracking", where you write "backtraces"? |
It did not work in the case of a subpattern containing backtracking. Temporary implement possessive quantifiers as equivalent greedy qualifiers in atomic groups.

Thank you @ferdnyc. Fixed. |
|
It is a last resort. It will be merged if we not find a fix for POSSESSIVE_REPEAT implementation before the next releases. |
|
Since 'the next releases' for Python 3.12 is today, do you want this in for 3.12.0 beta 4, or wait for rc1? |
|
I think it can wait for rc1, but we should not miss bugfix release for 3.11. |
|
rc1 is in a few days if you want this in before then. I don't think this is really a release blocker even if it does sound nice to fix. 3.11 users already have to deal with the bug existence even if we manage to get a fix into a patch release. |
