Alex Gaynor added the comment: Right, socket._socketobject mearly nulls out the reference to _socket.socket, and lets reference counting take care of the rest.
I've more of less got this figured out: * When do_handshake() raises an exception (say, a CertificateError), then a reference to a traceback is stored for sys.exc_info() * This traceback holds a reference to a frame where ssl.SSLObject is self * ssl.SSLObject holds a reference to _ssl._SSLSocket * Which holds a reference to _socket.socket This is avoided on Python3 because exceptions don't stick around, adding a ``sys.exc_clear()`` to that test causes it to not hang. It seems like ``ssl.SSLSocket.close()`` should probably explicitly close the ``SSLObject`` somehow? I think this problem would appear on Python3 if you caught the exception manually and kept a reference to it? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue22559> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
