Thanks to recent enhancements, epecially in bpo-46417, the last memory blocks are now released at Python exit! The initial issue has been fixed!!! This bug was 15 years old! Current main branch: $ ./python -I -X showrefcount -c pass [-5 refs, 0 blocks] "0 blocks" means that Python no longer leaks memory at exit. You can use Valgrind to check it ;-) The negative reference count is being discussed in bpo-46449. I close this issue since it has an insane history: too many pull requests, changes, etc. While the work is not 100% done (we need to convert remaining static types to heap types, and convert extensions to multi-phase init), I prefer to address remaining issues in (existing or new) separated issues. See for example the bpo-40077: "Convert static types to heap types: use PyType_FromSpec()". I would like to thank everybody who helped to fix this issue! It's hard to list all names since this issue is a meta issues made of many sub-issues which also have sub-issues. Authors of PEP 573 and PEP 630 also helped fixing this issue! ---------- resolution: -> fixed stage: patch review -> resolved status: open -> closed versions: +Python 3.11 -Python 3.10 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue1635741> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
