I've now skimmed through the relevant Trio issue https://github.com/python-trio/trio/issues/265 and the currently deferred https://www.python.org/dev/peps/pep-0533/ and, as I understand, the issue is not trivial and subject to subtle edge cases. Getting back to the issue, it looks like a misunderstanding on my side, sorry! As per PEP-525: The asyncio event loop will use sys.set_asyncgen_hooks() API to maintain a weak set of all scheduled asynchronous generators, and to schedule their aclose() coroutine methods when it is time for generators to be GCed. It seems that my original test case just doesn't give these aclose() coroutines a chance to run. Awaiting an asyncio.sleep() "fixes" that. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40986> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
