Category: Python Library Group: Python 2.4 >Status: Open Resolution: Works For Me Priority: 5 Submitted By: tdir (tdir) Assigned to: Vinay Sajip (vsajip) Summary: logging fileConfig swallows handler exception Initial Comment: If you specify a handler such as a RotatingFileHandler and the path you provide in the args specification ('option') is bad, config.fileConfig() catches the exception and 'swallows' it. The result is later on, when that handler is specified for a logger, you get an exception saying there is no such handler. A much friendlier behavior would be for fileConfig() to raise an exception so the real cause of the problem can be easily identified. Also, if there is a bug in the code itself, it would also get swallowed in similar fashion. In general, silently swallowing exceptions is rarely the best choice IMHO. Example ini with bad path (assuming /bad/path does not exist): [handler_defaultrotatingfile] class=handlers.RotatingFileHandler args=("/bad/path/logdir/my_log.log", 'w', 100000, 10) formatter=std ---------------------------------------------------------------------- >Comment By: tdir (tdir) Date: 2006-06-22 18:18 Message: Logged In: YES user_id=1541624 Python 2.4.2 (#67, Sep 28 2005, 12:41:11) [MSC v.1310 32 bit (Intel)] on win32 ABOVE IS THE PYTHON SIGNON I HAVE ALSO ATTACHED THE config.py FROM THE INSTALL.
