New submission from Alisue Lambda <lambdali...@hashnote.net>:
This is my first time to create an issue on the python bug tracker so let me
know if I don't follow the rule which I need to follow.
# Summary
Using 'loop.sock_connect' with 'asyncio.wait_for' raises 'OSError [WinError
10038]' in Windows 10 Pro when timed-out.
# Detail
I use 'loop.sock_connect' to establish a TCP connection for checking if a
particular port on a target host is available.
However, when I wrap the coroutine with 'asyncio.wait_for', the following
exception is raised when the wrapped coroutine has timed-out.
Traceback (most recent call last):
File "C:\Users\alisue/test.py", line 41, in <module>
loop.run_until_complete(test(loop))
File "C:\Python36\lib\asyncio\base_events.py", line 454, in
run_until_complete
self.run_forever()
File "C:\Python36\lib\asyncio\base_events.py", line 421, in run_forever
self._run_once()
File "C:\Python36\lib\asyncio\base_events.py", line 1395, in _run_once
event_list = self._selector.select(timeout)
File "C:\Python36\lib\selectors.py", line 323, in select
r, w, _ = self._select(self._readers, self._writers, [], timeout)
File "C:\Python36\lib\selectors.py", line 314, in _select
r, w, x = select.select(r, w, w, timeout)
OSError: [WinError 10038] ...........
While it is raised from 'lib\selectors.py', I cannot catch this exception so
the event loop has halted.
The attached 'test.py' is a minimum script to reproduce the error.
Thanks.
