New submission from STINNER Victor: While testing bpo-31234 fix, I noticed that some test_ssl tests using ThreadedEchoServer create reference cycles with ConnectionHandler: ConnectionHandler fills ThreadedEchoServer.conn_errors with exceptions, but exceptions keep an alive traceback object which contains frame locals.
I tried to use traceback.clear_frames(), but this function is broken: see bpo-31321. Attached PR works around the issue by storing errors are text rather than objects. The PR prevents warnings about dangling threads. ---------- components: Tests messages: 301116 nosy: haypo priority: normal severity: normal status: open title: test_ssl: reference cycle between ThreadedEchoServer and its ConnectionHandler type: resource usage versions: Python 3.7 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue31323> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
