New submission from Aleksey Kladov: The following hangs on Linux ```Python >>> import selectors >>> s = selectors.DefaultSelector() >>> s.select() ``` On Mac it returns an empty list. ------ messages: 254975 nosy: Aleksey Kladov priority: normal severity: normal status: open title: Selector.select() hangs when there is nothing to select versions: Python 3.5 ___ Python tracker <http://bugs.python.org/issue25680> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Aleksey Kladov added the comment: >What's the point of your bug report? To show surprising platform-dependent API behavior. I don't know what is the correct behavior here, but it should be cross platform. Seems like the most sane option is to throw an exception. >Does your application really rely on the behaviour of the selector when no >file descriptor is registered? It was developed on Mac and relied (quite probably incorrectly) on the empty list result. When I run it on linux, it unexpectedly hanged. So, I would like to either * observe an exception on all platforms * observe an empty list on all platforms * observe infinite blocking on all platforms I think this special case should also be mentioned in the docs. -- ___ Python tracker <http://bugs.python.org/issue25680> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Aleksey Kladov added the comment: >I disagree, we can do better than documenting "bugs" :-) The result of `select.select([], [], [], None)` should defintelly be documented. Three platoforms made three different decisions in similar situation, so any behavior is reasonable and it should be made clear which one is used by Python. -- ___ Python tracker <http://bugs.python.org/issue25680> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
