New submission from Sebastien Bourdeauducq <s...@m-labs.hk>:
The current behavior causes an exception to be raised when trying to create a datagram socket and _ipaddr_info returns None (since asyncio then calls loop.getaddrinfo with SOCK_STREAM and IPPROTO_UDP). Preserving socket type is made difficult by https://bugs.python.org/issue21327; the proposed patch includes a dirty workaround. I do not know yet if it works on Windows. --- selector_events.py 2018-05-11 10:01:42.011164837 +0800 +++ selector_events.py.new 2018-05-29 17:41:03.103155480 +0800 @@ -439,8 +439,9 @@ raise ValueError("the socket must be non-blocking") if not hasattr(socket, 'AF_UNIX') or sock.family != socket.AF_UNIX: + socktype = sock.type & 0xf # WA https://bugs.python.org/issue21327 resolved = base_events._ensure_resolved( - address, family=sock.family, proto=sock.proto, loop=self) + address, family=sock.family, type=socktype, proto=sock.proto, loop=self) if not resolved.done(): yield from resolved _, _, _, _, address = resolved.result()[0] ---------- components: asyncio messages: 318001 nosy: asvetlov, sebastien.bourdeauducq, yselivanov priority: normal severity: normal status: open title: selector_events.BaseSelectorEventLoop.sock_connect should preserve socket type type: behavior versions: Python 3.5, Python 3.6 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue33678> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
