Hi Ian
I ran into this just recently, but am not entirely certain I found the best
solution. I needed to be able to switch the port the reactor was listening
on without restarting the reactor. Here's how I did it:
def startListener(self, port, interface="127.0.0.1"):
self.iListeningPort = reactor.listenTCP(
port,
self.factory,
interface=interface
)
def restartListener(self, port, interface="127.0.0.1"):
self.iListeningPort.stopListening()
self.startListener(port, interface)
I'm not sure if doing this will have any unintended side-effects, but so far
it seems to have done the trick. If someone else on the list could confirm
this does what I think it does (and what Ian is looking for) that would be
great.
Best,
Travis

I have created an internet server that is started in a thread from a Python QT GUI.
I can call reactor.stop() and sucessfully get notified of shutdown and the run thread terminates, the TCP/IP listen port is closed.
When I restart it by calling reactor.listenTCP() and reactor.run(installSignalHandlers=0) a second time I find that things don't work correctly. e.g. TCP calls are accepted and my protocol.dataReceived() is called but then calling reactor.callInThread(self.blockingMethod, data) does nothing. Also calling stop() a second time does not stop the running reactor thread or terminate the TCP listener.
I have tried numerous options, and have been careful to avoid any conflicts with the GUI threads. It appears that the reactor is not being restarted correctly after stop() and a second run().
What I need is to stop and re-start the listenTCP. Is there a way to do this?
Thanks, Ian
