[Twisted-Python] Question about Writing a Stackless Friendly Reactor
Hello : I have been using Twisted with Stackless. I am interested in writing a more Stackless "friendly" reactor. I believe a stackless friendly reactor would call stackless.schedule() whenever possible. I notice there are different types of reactor. I have been looking at SelectReactor and its base case, Posixbase. It seems easy enough to modify MainLoop to put in a stackless.schedule(). However this approach does not seem to be the most maintainable or effective, since I would be overriding MainLoop only to put in one line. What is the proper Twisted approach to doing this?

Please see the archives for previous discussions on this topic. Thanks, Jean-Paul

I disagree. Separate reactor implementations are for different OS multiplexing mechanisms. stackless.schedule() should *not* be called "whenever possible", but rather, whenever stackless tasks have something to do.

Don't implement a reactor :). I recently replied to a very similar question in a different thread: http://article.gmane.org/gmane.comp.python.twisted/13946 What about my answer there was not clear?
