I'm quite sure there's more people out there familiar with Twisted than there are people familiar with eventlet. Twisted has been around for a while. That's also good for recruiting. > - It's a weaker argument, but it's really hard to find any comparisons > between Twisted and Eventlet on the web that say Twisted is preferable > (has anyone found any?)

It's been suggested several times that we implement something using eventlet, so that we have something concrete to compare. I'm fine with that thing being the RS API, so that we can add some substance to this discussion. I think that's a better basis for a decision than knowing that someone having told someone else something (which we don't know what is) about two different things, and these people (who are not the people working on Nova) felt they liked one of the things more than the other. I agree it's a data point, but I'd like to make my decisions based on my own opinions rather than those of strangers. I think I've said it before, but I'd like to say it again: I really don't mind code looking asynchronous if I expect it to act asynchronously. Stuff happens, it gets handled. The Twisted framework provides a bunch of protocols that let you write code this way and it's easily extensible. Once you get the hang of that it's really quite straightforward. Most people aren't used to writing async code, so it may take them a little bit to wrap their heads around it if they want to architect new components, but for the odd bugfix, I really don't thinks it's something you need to worry too much about. I think it's being made out to look like using Twisted makes it take a Herculean effort to write even the simplest things, while Eventlet code magically writes itself. I doubt that's really the case. Twisted is a big framework with a bunch of code to do common things that are a chore with the Python's standard library. Eventlet may let you use the standard library in an asynchronous way, but you're still stuck with the standard library :) -- Soren Hansen Ubuntu Developer http://www.ubuntu.com/ _______________________________________________ Mailing list: https://launchpad.net/~nova Post to : [email protected] Unsubscribe : https://launchpad.net/~nova More help : https://help.launchpad.net/ListHelp
