STINNER Victor added the comment: I wrote https://github.com/python/cpython/pull/3029 which seems to fix the issue.
I don't know importlib well enough to understand why we need a weak reference to a lock. My PR adds a second lock per module lock (!) to be able to wait until _module_locks[name] is deleted when a thread detects that _module_locks[name] exists and the associated lock was destroyed. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue31070> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
