No. Wait there... AMPConnector is only a frontend and it's not made to be inherited. You might want to inherit it only to add some weird functionality to it. Another option is to not use it but create a new one to avoid using AMP as a child-parent protocol. You really want to subclass AMPChild and create a good AMPParent by subclassing amp.AMP. There are some examples in the code and to expose a process pool on the net you shouldn't do anything more than adding the right argument to the command line twistd plugin.
Two more questions: What's the mechanism of 'registring' multiple twisted servers (something similar to a Name server in Corba) -- so an event dispatching client can 'discover' the servers running on multiple machines
I haven't written such a mechanism yet. It shouldn't be too hard to have a simple version but having everything go through the same master nodeis kind of problematic from a scalability point of view. It would be better to
have a routing system where each system knows each other but probably this has a lot of memory overhead to keep in memory the list of nearbyservers... If anyone is willing to spend some time to design some kind of solution for this I'd be happy to implement it in ampoule. I'm pretty sure that
this was done in other projects already.
And how does one run multiple XAMPP servers in twisted -- such that work to each server is distributed either by a hash on a user name or some other way (or does such mechanism exist).
It's just AMP, XMPP is another protocol. -- Valentino Volonghi aka Dialtone Now running MacOS X 10.5 Home Page: http://www.twisted.it http://www.adroll.com
