Hi. For Zope 2.13 (trunk) I'd like to try to reduce the C dependencies of the Zope2 distribution itself. Ideally it would not have any C dependencies in its own distribution, but that's a bit too much for now. As a next step I'd like to split out the initgroups, Missing, MultiMapping, Record and ThreadLock packages into their own distributions. The code in these hasn't changed in years and I don't see this changing anytime soon. If this is done the remaining C libraries are in AccessControl, DocumentTemplate and ZCTextIndex. AccessControl has a reference implementation in Python and could the C library could be made an optional optimization. The ZCTextIndex okascore.c and stopper.c should also be relatively easy to do as Python implementations. DocumentTemplate has a pDocumentTemplate.py module as a reference implementation, which clearly states that it is outdated. This would need to be updated to match the C implementation. Hanno
