I can reproduce on 3.9.6 A little digging and it seems asyncio imports Task from _asyncio and _asyncio's implementation (in asynciomodule.c) of Task has an __init__ which adds the task to the `all_tasks` weakref.WeakSet which appears to be implemented in Python (in Lib/_weakrefset.py) weakref.WeakSet is not thread-safe, which means concurrent create_task's in different threads (even on separate event loops) is not safe. ---------- nosy: +bjs _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue44962> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
