I'm not familiar with the reasons Twistd moved from .tap to .tac (it's rather before my time), but as a user I'd be worried about things like "what happens if, due to a bug, the server winds up choking on some unexpected input, or deadlocked, or just mis-files some piece of state?" Restarting the process in question is a sledgehammer approach, but that's often what you want if the alternative is unscheduled downtime. The difference between Pickle and SQLite is that a SQLite database has probably had some thought put into its schema, and is much less likely to accidentally scoop up random other objects by reference. Also, if your database *does* pick up some unwanted state, you have the option of tinkering with the database manually; something that's much more difficult to do with pickles. I'd be interested in hearing from Twisted greybeards why .tap was deprecated, but I don't think your IRC bot has a fatal design flaw. _______________________________________________ Twisted-Python mailing list Twisted-Python@twistedmatrix.com http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python
