| I marked the issue #272989 as a duplicate of this one. Copy of the by Terry J. Reedy: 3.6, Windows 10, debug build. The following appeared before and after pulling and rebuilding today. I am reporting as per Victor's request on pydev list. 0:00:22 [ 52/402] test_asyncio passed F:\Python\dev\36\lib\asyncio\sslproto.py:329: ResourceWarning: unclosed transport <asyncio.sslproto._SSLProtocolTransport object at 0x03B57658> source=self) F:\Python\dev\36\lib\asyncio\sslproto.py:329: ResourceWarning: unclosed transport <asyncio.sslproto._SSLProtocolTransport object at 0x03B57E70> source=self) F:\Python\dev\36\lib\asyncio\sslproto.py:329: ResourceWarning: unclosed transport <asyncio.sslproto._SSLProtocolTransport object at 0x03AA9038> source=self) |

| From my observations, this is due to transport is forgotten to close in test_connect_accepted_socket. Upload a patch to add the close function. |

| I was about to report this same issue - I get the error message even though I explicitly call transport.close(): C:\Python35\lib\asyncio\selector_events.py:582: ResourceWarning: unclosed transport <_SelectorDatagramTransport closing fd=232> It looks like the _sock attribute of the Transport subclasses must be set to None in their close() methods. (The presence of a non-None _sock is used elsewhere as an indicator of whether the transport has been closed or not. |

| The patch I submitted is about to solve the resource leak in the test suite. Paul, your problem seems to need other triage. |

| @Paul: close() is asynchronous in Python :-) |
