New submission from tzongw <tzo...@163.com>:
In `tasks.gather`, when a child future throws an exception and `return_exceptions` is False, outer future will call `set_exception` while other child futures is still running. In this case, outer future call `_GatheringFuture.cancel' first to cancel all other pending child futures for efficiency. ---------- components: asyncio messages: 323755 nosy: asvetlov, tzongw, yselivanov priority: normal severity: normal status: open title: cancel all other pending child futures type: performance versions: Python 3.6 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue34433> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
