The main thread closes a file descriptor which is part of the asyncore loop "map", a thread polls on the asyncore "map" file descriptors. -- Main thread -- Close a socket: File "/usr/home/vstinner/python/master/Lib/test/test_logging.py", line 1072, in test_basic server.stop() File "/usr/home/vstinner/python/master/Lib/test/test_logging.py", line 870, in stop self.close() -- TestSMTPServer thread -- Wait in asyncore.loop(): Exception in thread Thread-1 (serve_forever): Traceback (most recent call last): File "/usr/home/vstinner/python/master/Lib/threading.py", line 990, in _bootstrap_inner self.run() File "/usr/home/vstinner/python/master/Lib/threading.py", line 928, in run self._target(*self._args, **self._kwargs) File "/usr/home/vstinner/python/master/Lib/test/test_logging.py", line 863, in serve_forever asyncore.loop(poll_interval, map=self._map) File "/usr/home/vstinner/python/master/Lib/asyncore.py", line 211, in loop poll_fun(timeout, map) File "/usr/home/vstinner/python/master/Lib/asyncore.py", line 145, in poll r, w, e = select.select(r, w, e, timeout) OSError: [Errno 9] Bad file descriptor |
