New submission from Марк Коренберг <socketp...@gmail.com>:
Proof: ================ import asyncio async def test(): while True: print('sleeping 1') await asyncio.gather(asyncio.sleep(1), return_exceptions=True) async def amain(): print('creating task') qwe = asyncio.Task(test()) print('sleeping 2') await asyncio.sleep(2) print('cancelling task') qwe.cancel() print('waiting task for completion') try: await qwe except Exception as e: print('task complete: %r', e) loop = asyncio.get_event_loop() loop.run_until_complete(amain()) ================ This program will never complete. This case should be either fixed, or documented. ---------- components: asyncio messages: 310843 nosy: asvetlov, socketpair, yselivanov priority: normal severity: normal status: open title: asyncio.gather(..., return_exceptions=True) swallows cancellation type: behavior versions: Python 3.5, Python 3.6, Python 3.7, Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue32684> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
