Repro:
1. Run the attached script ('repro.py')
Expected output:
2018-07-31 16:39:57,069 - asyncio - DEBUG - Using proactor: IocpProactor
2018-07-31 16:39:57,084 - root - INFO - Starting
2018-07-31 16:39:58,100 - root - INFO - Sleep done
2018-07-31 16:39:58,100 - root - INFO - Loop closed
Actual output:
2018-07-31 16:37:58,583 - asyncio - DEBUG - Using proactor: IocpProactor
2018-07-31 16:37:58,599 - root - INFO - Starting
2018-07-31 16:37:59,614 - root - INFO - Sleep done
2018-07-31 16:37:59,614 - asyncio - DEBUG - taking long time to close proactor
2018-07-31 16:37:59,614 - root - INFO - Loop closed

I *suspect* the issue is down to a discrepancy between: - IocpProactor.close(), and - IocpProactor._poll() When the former calls the latter, it seems to be expecting a truth value response from _poll() to indicate that no timeout occurred. However, the latter only ever returns None. Of note is that `ms != 0` whenever a timeout occurs, potentially giving a simple test point. |
