I am not so interested in "debug runs", but more in a way to get more informations of our tool stack bugs when run in production. I guess what I am looking for is some good practices for dealing with errors, then. Maybe a piece of code in twisted itself ? cheers, David _______________________________________________ Twisted-Python mailing list Twisted-Python@twistedmatrix.com http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python
