Category: Python Library Group: None >Status: Closed >Resolution: Invalid Priority: 5 Submitted By: Boris Lorbeer (blorbeer) Assigned to: Vinay Sajip (vsajip) Summary: method format of logging.Formatter caches incorrectly Initial Comment: The format method of logging.Formatter is buggy in that it doesn't call the method formatException if the cache record.exc_text is set. If you have two Formatters that should format the same log record differently (i.e. each has its own overriding formatException method), the formatException method of the second formatter will never be called because the cache has been set by the first formatter. The proper way of using the cache is IMHO to check the cache only in the method formatException of logging.Formatter. ---------------------------------------------------------------------- >Comment By: Vinay Sajip (vsajip) Date: 2006-06-22 16:46 Message: Logged In: YES user_id=308438 It's not a bug, it's by design. The formatException method only takes the exception info as a parameter, and to change the method signature now could break some people's code, right? A solution would be for you to also override the format method in your custom formatter classes and set record.exc_text to None if you want to invalidate the cache before calling the base class implementation. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=105470&aid=1501699&group_id=5470 _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
