This is a replacement for a traceback. In later Python versions, the full traceback is printed. In the general case it represents a bug in the code that should be fixed. Most such errors arise from the vagaries of module finalization (such as your issue 19021), but not all of them do: the rest represent real bugs in __del__ methods (which are executed asynchronously in the general case). So the question is, is the bug in the user code, or the stdlib code? >From the issue, it sounds like it could be considered either (or most likely, both). --David _______________________________________________ Python-Dev mailing list [email protected] https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
