I wrote PR 12743 to modify _abc: use weakref.WeakSet rather than using directly a set of weak references. With this PR, calling _get_dump() should clear all broken weak references. I'm not sure if it's really useful for this specific issue, since dash_R_cleanup() calls obj._abc_caches_clear() on all abstract base classes (ABC): all caches must be removed before reading the total number of allocated memory blocks (sys.getallocatedblocks()). ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue36560> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
