If you call socket.setdefaulttimeout() to enable timeout mode, then create a POP3-over-SSL connection by instantiating a poplib.POP3_SSL() object, the resulting connection can hang because the underlying socket.ssl() object doesn't work when timeouts are enabled. If, after creating the POP3_SSL object, you call object.conn.sock.setblocking(1), the hangs will not happen. This is exactly the same bug as happened with IMAP SSL connections, as I reported in bug #977680. The Python documentation still does not mention that socket SSL support is not compatible with socket timeout support.

Logged In: YES user_id=139606 It's just broken in _ssl.c. In PySSL_SSLread() there is: sockstate = check_socket_and_wait_for_timeout(self->Socket, 0); It hangs here because that function waits for new data on the socket but SSL layer could already read that data.
