You are right, my approach is too complicated and only needed when the OP cannot modify the sending script -- which is unlikely. > This is the approach used by the examples in the library documentation > which pickle events for sending across a network: > > http://docs.python.org/howto/logging-cookbook.html#sending-and-receiving- logging-events-across-a-network > > The built-in SocketHandler pickles the LogRecord's __dict__ rather > than the LogRecord itself, precisely because of the improved > interoperability over pickling the instance directly. As a minimal change ensuring that the logging.LogRecord subclass used by the OP is a newstyle class in 2.6 with class LogRecord(logging.LogRecord, object): #... should work, too. -- http://mail.python.org/mailman/listinfo/python-list
