Hi. I've started working some more on my pet project of refactoring Zope2 - specifically to move all C code to external distributions. My working branch is at svn+ssh://svn.zope.org/repos/main/Zope/branches/hannosch-dtml-vs-accesscontrol which also has a TODO.txt with some notes. On the branch DocumenTemplate imports from AccessControl but not the other way around. So in general I think this can be made to work. My current plan involves: - Move Shared.TaintedString to an external distribution. It's used both by DocumentTemplate and ZPublisher. Moving it into DocumentTemplate and have ZPublisher depend on it, sounds like a poor choice to me - a publisher shouldn't depend on a markup language. We could also move it into AccessControl as it's sort of a security feature. - Move zExceptions to an external distribution. It's used from all over, but has no external dependencies on its own. Instead of just moving it out, I'd look at merging some of it into zope.exceptions. The two share a good deal of code like the exception formatter and common exception classes. - Move the ZMI parts of AccessControl into the App package. App already holds a good deal of general ZMI pages, so this seems a good fit. It basically makes App the zope.app of Zope2. There's a bunch of more minor stuff to work out and lots of awful test dependencies, but in general it looks good. If you have any feedback on the above, please shout - otherwise I'll continue as planned and time permits. Once this is finished and merged, ZCTextIndex holds the last bits of C code inside the Zope2 distribution - there's multiple ways to deal with it: break it and HelpSys out or reuse the C code from zope.index. We can look at that later. Hanno
