I'm making an IRC client using Twisted, and I want to connect to a different server when connection fails, but I haven't been able to figure out how to do that.. Here's a more or less minimal code sample reflecting what I have now: ------------------------------------------------------------------------------------------------ from twisted.words.protocols import irc from twisted.internet import protocol from twisted.internet import reactor class ServerConnection(irc.IRCClient): def __init__(self): self.signedon = False self.nickindex = 0 def signedOn(self): print("signed on") def nickChanged(self, newnick): self.nickname = newnick class Network(object): def __init__(self, servers, mynick=None): self.servers = servers self.mynick = mynick self.serverindex = 0 class ServerFactory(protocol.ReconnectingClientFactory): def __init__(self, nickname="qttwirc", password=None, username="qttwirc", realname=None, network=None): self.network = network self.network.mynick = nickname self.nickname = nickname self.username = username self.password = password self.realname = realname protocol.ReconnectingClientFactory.initialDelay = 10 #should i leave this at 1? protocol.ReconnectingClientFactory.maxDelay = 10 #no idea what value this should be. 3.5 wasn't slow enough, i was being throttled. def buildProtocol(self, addr): p = ServerConnection() self.serverconnection = p p.server = self p.nickname = self.nickname p.username = self.username self.resetDelay() return p def clientConnectionLost(self, connector, reason): self.serverconnection = None protocol.ReconnectingClientFactory.clientConnectionLost(self, connector, reason) def clientConnectionFailed(self, connector, reason): self.serverconnection = None addr, port = self.network.servers[self.network.serverindex] self.network.serverindex = (self.network.serverindex+1) % len(self.network.servers) #todo: make it actually use these values #reactor.callLater(config.reconnectdelay, reactor.connectTCP, addr.encode("ascii"), port, self) #reactor.connectTCP(addr, port, self) #is this feasible? i don't know a better way to do this. connector.connect() apparently doesn't take server/port as arguments. protocol.ReconnectingClientFactory.clientConnectionFailed(self, connector, reason) network = Network([("hitchcock.freenode.net", 6667), ("verne.freenode.net", 6667)]) server = ServerFactory(nickname="test123", username="test123", network=network) reactor.connectTCP(*network.servers[network.serverindex], server) reactor.run() ------------------------------------------------------------------------------------------------ If I have to completely change the structure of how I connect, that's fine.. I don't understand Twisted very well, so I'm not aware of what some other options are for how to make an IRC client. (It probably doesn't matter, but in my actual program I'm using both Twisted and PyQt5 in the same run loop using qt5reactor..) Thanks.
