Question

I have the following code. I am trying to get reactor to run on the ports starting at 1025 + NUM_TABLES. The issue is that when I call reactor.run() in the loop, the loop freezes. When it is commented, the loop counts from 0 to 9, but when it is uncommented, it only prints 0.

NUM_TABLES = 10

factories = [ ]
for i in range(0, NUM_TABLES):
    print i
    factory = Factory()
    factory.protocol = Socket
    factory.clients = []
    factories.append(factory)
    reactor.listenTCP(1025+i, factory)
    #print "Blackjack server started"
    reactor.run()

WHat does it take to be able to run a new factory on a different port? Why does reactor stop at 0? It has worked before, why not now? Thanks.

Answer 1

Don’t call reactor.run() until all of your listeners have been created and registered. It’s meant to be the last call you make directly from your main script; everything after that is callbacks.

To clarify, just un-indent the last line one level.
