STINNER Victor <vstin...@python.org> added the comment:
For me, there are different issues: * PyType_FromSpec() must fail if a type is declared with Py_TPFLAGS_HAVE_GC but its tp_traverse function is NULL. * _ssl.SSLError must implement the tp_traverse slot Moreover, in debug mode, PyObject_GC_Track() calls the traverse function to ensure that it's safe to call it. PyObject_GC_Track() must crash of tp_traverse is NULL. If it didn't track, it means that the _ssl.SSLError instance was not tracked by the GC. Is that ok? Objects implementing the GC protocol should be tracked by the GC, no? An exception is *likely* to be part of a reference cycle because it contains a traceback which contains frames which contains variables, and one variable can be the exception. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue44252> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
