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.
