I'm trying to work out how to use WSGI with Zope, as I believe that this is the way to attach a filter to Zope output. However the seem to be some issues with Zope 2.10.3. Setting use-wsgi on in zope.conf seems to break Five. The interfaces tab is no longer visible in the ZMI and Plone stops working (giving me an AttributeError: @@plone). This seems tricky to debug though as ZPublisher.test still works.

Changing ZPublisher.Test.publish_method to use WSGIPublisher.publish rather than Publish.publish brings up the zope 3 security issues when running the Five tests as bug #2190, but these can be fixed with the same interaction fix that Philipp applied to Publish.py in r71819 (see attached diff). Having applied this fix I still get the same problems with AttributeError: @@plone and the manage_interfaces tab not showing up.


If anyone has an example of attaching a filter to Zope output using WSGI you'd make my day.
