I have a producer sort of working thanks to this :
and this post :
I have a question though, I was looking at the way all this works by
using a debugger, and I noticed that in twisted.internet.abstract.py in
registerProducer() there is the following :
if not streaming:
Why is this done only for the pull producer? Shouldn't it also be called
for the push producer since to have the data sent one has to call either
self.transport.write() or resumeProducing() anyways? If you look at :
it does :
thus starting the writing process and in the pull producer :
it doesn't need to start the writing process explicitly since it's
started when the producer is registered.
