Thanks for the very interesting example which I mainly follow apart from the
lineReceived method in the ProxyClient, don't we need to add a callback to
the deferred before appending it to the requestQueue?
class ProxyClient(LineReceiver):
def connectionMade(self):
self.requestQueue = []
def forwardLine(self, line):
self.sendLine(line)
d = Deferred()
self.requestQueue.append(d)
return d
def lineReceived(self, line):
self.requestQueue.pop(0).callback(line)
Thanks, Michael
