The problem is that NOX doesn't handle multiple threads in Python. The
solution is to just scrap the thread. NOX already has a reactor running, so
just set up your protocol and you should be good to go -- all you need is the
following in the install() method:
factory = Factory()
factory.protocol = QOTD
reactor.listenTCP(8007, factory)

Hello,
I am trying to run a thread inside of a python NOX component using twisted that
listens for TCP connections. I added code to pyswitch.py to see if I could get
it working. However, I am getting this seg fault from NOX. It seems to be
failing at 'reactor.listenTCP(8007, factory)'. Any ideas on what the problem
might be?
Added code:
class ServerThread(Thread):
def run(self):
print "Thread started"
factory = Factory()
factory.protocol = QOTD
reactor.listenTCP(8007, factory)
reactor.run()
class QOTD(LineReceiver):
def connectionMade(self):
self.transport.write("Vene, vidi, vici\n")
self.transport.loseConnection()
I added the following two lines at the end of pyswitch's install method:
self.serverThread = ServerThread()
self.serverThread.start()
NOX Output:
