At some point in the past, somebody decided it would be a great idea to have Twisted's "twistd" start applications from Python pickles; you could start up a server, configure it interactively, and when you shut it down the entire server state would be persisted in a pickle-file; when you started it up it would resume exactly as it had been when you shut it down. The idea seems to have fallen from grace, possibly because restarting a process is often the simplest way to resolve a production problem. These days, new Twisted users are encouraged to use Python ".tac" files rather than ".tap" pickles, and I expect that sentence is just a relic of that bygone era. _______________________________________________ Twisted-Python mailing list Twisted-Python@twistedmatrix.com http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python
