New submission from Govinda Totla <govinda.totla.cs...@itbhu.ac.in>:
The logging module allows you set a custom Logger class as the default logger. However, this breaks when we try to copy the logger which was created before setting the logger class ``` import copy import logging # Some module we don't control oldLogger = logging.getLogger("abc") # Some module where we want to change over to custom logging class MyLogger(logging.Logger): pass # Override the manager, root, etc., so everything uses our class logging.setLoggerClass(MyLogger) logging.root = root = MyLogger("", logging.WARNING) logging.Logger.manager = logging.Manager(root) newLogger = logging.getLogger("def") # Later on this happens, which internally calls __reduce__ copy.deepcopy(oldLogger) ``` ---------- components: Library (Lib) messages: 414750 nosy: govinda18 priority: normal severity: normal status: open title: Logger with a custom class breaks on copy type: crash versions: Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue46957> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
