Hi Martijn, it's good to see that someone other than me is monitoring the check-ins and this response allows me to give an update about the server code.

Yes, though WSGI is not as much magic as everyone expects. If you want to connect to another Web server, you will have to write some glue code, but it demonstrated in the zope/app/wsgi/README.txt file what has to be done. I hope that through the Twisted integration we will see some opportunity to generalize and *maybe* we can find a way to allow changing servers by modifying a couple of lines in a configuration file. > And the WSGI support in ZServer mean that Zope 3 can function as a WSGI > server itself? Yes. Instead of passing in a request factory, as it is the case for the publisher HTTP server, you pass in the application callable. This is very easy indeed. Note though, that we are not planning to support zope.server anymore and we will switch to twisted only. I basically did the ZServer WSGI version as an exercise for the Twisted integration. > Is the Twisted integration based on WSGI? Twisted is not integrated yet; I have only created a link to their repository and made the required license remarks. But the new twisted.web2 code is WSGI compliant and we will connect to it via WSGI. But the first step will have to be to throw out the old ZServer loop and replace it by Twisted's. Once this is done, adding servers, be it HTTP (via WSGI or not), FTP, SMTP, or others should be a fairly straightforward task. Also note that WSGI makes it much harder to include the user in the logging (i.e. the current approach will not work) and it will be trickier to implement clean server shutdowns and restarts. Since Itamar lives in Cambridge these days, we are going to meet this weekend and work on the full Twisted integration. I hope that foom (James), the author of twisted.web2, will be able to join us as well. > I'd be interested in seeing > Apache mod_python integration using WSGI as well, though I think > mod_python WSGI support is still behind... I think Phillip v.

Thanks, but actually I am just interested in the Twisted integration, since I really want to see how we can hookup other protocols such as SMTP and POP3 to Zope 3. Jim really wanted WSGI for the HTTP server and since Twisted supports it I thought I learn about it some more; thus the documentation cleanups and interfaces.
