[Zope-dev] WSGIPublisher and Five

[Laurence Rowe]

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.
