Integration as an optional feature or replacement of ZPublisher/ZServer?The direct goal of this is to make it more pluggable, so that we can introduce twisted or zope.publisher as alternatives. Twisted, so that we can write new servers for Zope2, and zope.publisher, so that we can closer to the goal of being able to run both Zope3 and Zope2 software under the same server.
The long term goal is to replace ZServer/ZPublisher with whatever Zope3 uses, which at that point in time most likely will be twisted/zope.publisher, to tighten the Z2/Z3 integration, and reduce the amount of code we need to maintain.
Getting rid of ZServer is a fine goal but as long as Twisted is much slower (from what I've heard) ZServer has to stay (ZServer is not subject to be deprecated at this time).
The risks is that somehow we introduce some subtle behavioural change that isn't tested for.
I would love to see the stuff tested with the major frameworks (CMF 2, Plone + CPS) before it will be merged into the trunk.
The traversal refactoring means that the role checking is now done after each traversal step, instead of intermingled with it. The functionality should be the same, but perhaps there is some untested special case when it changes. We have had much larger incompatibility changes in earlier major releases though. The WSGI refactoring may mean that somebody using internal features of ZServer might need to change something. Also it means that what the publish_module() method expect as parameters will change.
I have no problems with the traversal refactoring..that sound sane. -aj -- ZOPYX Ltd. & Co. KG - Charlottenstr. 37/1 - 72070 Tübingen - Germany Web: www.zopyx.com - Email: [EMAIL PROTECTED] - Phone +49 - 7071 - 793376 E-Publishing, Python, Zope & Plone development, Consulting
