Hi all, I'm learning Twisted by reading Abe Fettig's "Twisted Networking Programming Essentials". I tried the example 2-6 (dataforward.py) but the program hung after printing 'Connected to ...'. I don't know Twisted enough to figure out where the problem is. Will anybody tell me why? I paste the code here: -------------------------------------------------------------- from twisted.internet import stdio, reactor, protocol from twisted.protocols import basic import re class DataForwardingProtocol(protocol.Protocol): def __init__(self): self.output = None self.normalizeNewlines = False def dataReceived(self, data): if self.normalizeNewlines: data = re.sub(r"(\r\n|\n)", "\r\n", data) if self.output: self.output.write(data) class StdioProxyProtocol(DataForwardingProtocol): def connectionMade(self): inputForwarder = DataForwardingProtocol() inputForwarder.output = self.transport inputForwarder.normalizeNewlines = True stdioWrapper = stdio.StandardIO(inputForwarder) self.output = stdioWrapper print "Connected to server. Press ctrl-C to close connection." class StdioProxyFactory(protocol.ClientFactory): protocol = StdioProxyProtocol def clientConnectionLost(self, transport, reason): reactor.stop() def clientConnectionFailed(self, transport, reason): print reason.getErrorMessage() reactor.stop() if __name__ == '__main__': import sys if not len(sys.argv) == 3: print "Usage: %s host port" % __file__ sys.exit(1) reactor.connectTCP(sys.argv[1], int(sys.argv[2]), StdioProxyFactory()) reactor.run() ----------------------------------------------------------------------- Thanks in advance.
