[Twisted-Python] How to use defer.fail better...

Hoi all, I'm writing a twisted/python SMTP server that accepts emails from a MTA using twisted. All works well, except that when I return a defer.fail(None) from processEmail to messageHandler.eomReceived (see below), twisted dumps the trace back of the last exception on stdout. Is there a way to

[Twisted-Python] What kind of throughput can we expect to achieve when using DatagramProtocol (UDP)

Hi, We have an application we intend to release where we intend to have about a million applications sending UDP packets to a Twisted Python server which needs to process incoming data (Approx 128 bytes of text) per packet, which a BACK end system is inserting this data into mySQL tables.

[Twisted-Python] New user - plugin question

Hello, I'm a long time linux/python user who's just now starting to use twisted. I am looking for advice more than anything specific. We're working on a small game/etc server that has several small games that can be played between users. Maybe a card game, tic-tac-toe, etc. There are a l
