There is a periodic call you may insert in to any event loop. Other than that there is a function you call when you recv a packet, and you pass it a function handle to call when it needs to send a packet. So, in the implementation on Twisted, I use a normal Twisted UDP socket to send an receive packets, and a task.LoopingCall to run the periodic call. That's it. I was able to get it running on Twisted very easily, using the direct uTP API. I built an ITransport out of it, which wasn't too much trouble, and even took a swing at the Client/Server/Connection/Connector pile of objects to implement reactor.connectUTP and reactor.listenUTP. Those have a lot of edge cases around when the connection is lost or manually closed, which I'll need to test, but it seems to work at a basic level. -Greg _______________________________________________ tahoe-dev mailing list tahoe-dev@allmydata.org http://allmydata.org/cgi-bin/mailman/listinfo/tahoe-dev
