Hi all, I recently upgraded to 0.14.0, but I'm still seeing Factory.startFactory() being called twice when I start my server. If I start my server with the following code (adapted from simpleserv.py): app = Application('spam') app.listenTCP(1234,MyFactory()) app.run(save=0) Then by using traceback.format_stack() in MyFactory.startFactory I can see that it gets called twice, here: app.run(save=0) File "F:\Python22\Lib\site-packages\twisted\internet\app.py", line 350, in run port.startListening() File "F:\Python22\Lib\site-packages\twisted\internet\tcp.py", line 395, in startListening self.factory.startFactory() and here: app.run(save=0) File "F:\Python22\Lib\site-packages\twisted\internet\app.py", line 357, in run port.factory.startFactory() I'm currently using if not hasattr(self, 'once'): self.once = 1 # ... To workaround it, but it'd be nice to not need to do this. The docs suggest that it will get called twice, "both after an application has been unserialized and before all the ports begin accepting connections." Which is fine, except that I'm not unserialising... It's a minor glitch in an otherwise beautiful system :) -Andrew.
