Perhaps this should also be mentioned on the "Choosing a Reactor" page for completeness? The "choosing a reactor" document could definitely be made clearer; please feel free to submit a doc patch that will help others with this.

Hi there, I'm trying to do some reverse DNS lookups with twisted and I don't seem to be able to get even the most simple of test cases to work. I've tried it on a couple of different installations with the same results, perhaps someone can help me? My test case is this: ---------------------------------------------------------------------------------- from twisted.names import client from twisted.internet import reactor def callback(a): print repr(a) client.lookupPointer('128.244.209.91.… [View More]

[Twisted-Python] Simple Epoll Reactor question
by Andrew Francis July 18, 2009

July 18, 2009

Hi Folks: I am trying to use the epollreactor. I read the "Choosing a Reactor" page. However I am not clear on how to actually install and use epollreactor. I thought I could do the following: from twisted.internet import epollreactor .... # epollreactor.install() epollreactor.listenTCP(8000, MyHttpFactory()) epollreactor.run() I get AttributeError: 'module' object has no attribute 'listenTCP' What am I doing wrong? Thanks in advance. Cheers, Andrew
