That indicates a lack of test coverage: classes which claim to implment interfaces on behalf or their instances need tests (via 'zope.interface.verify.verifyClass'). For example the IContentProvider interface requires the render method to be def render(*args, **kwargs). Almost no viewlet is complying to this starting with the base viewlet manager zope.viewlet.manager.ViewletManagerBase which accepts no arguments. Passing in the view to the render method therefor doesn't work (render is often directly the template). Let's just fix the viewlet classes, then. As a result I have abandoned this plan as well.

Is there a TODO of what is pending to finish it? The good news is that all Zope tests are passing and all the heavy lifting is done. The bad news is that there is one rather nasty minor problem with the branch. Now we were able to remove Acquistion wrapping and base classes from a lot of places in Five. In almost all places this would cause no problem, and following __parent__ pointers instead would do the trick. The only place where this turned out to be tricky is the ViewPageTemplateFile aka ZopeTwoPageTemplateFile of Five (found in Products.Five.browser.pagetemplatefile). The main difference between the Zope3 and the former Zope2 version is the way those get to know the view which they operate on. In Zope3 the view is always passed in as the first argument to the __call__ method, the argument is called instance here. The Zope2 version so far depended on Acquisition to get to the view. As we removed Acquisition wrapping from a lot of places, the ViewPageTemplateFile doesn't have any proper AQ context anymore to work with. For most cases this isn't a problem as the view is passed in as the first argument as well in Zope2, but looking through the Plone codebase (which we used as a real-life testcase for interesting uses of Five technology) it turned out that there are various different ways of usage out there, which wouldn't pass in the view. Those do work right with current Zope and obviously need to keep working for BBB reasons. The only way I found to get this working without reintroducing AQ-wrapping all over the place again, which kind of defeats the purpose of this branch, is to walk up the stack frames to get to the view. I hacked this version just yesterday and it still produces some TraversalError for 'macros' in some cases. If you want to test this, just create a Plone instance from the Plone 3 SVN branch, try inline-editing on the front-page, @@manage-portlets, creating a new content-rule inside the control panel and looking at the mail control panel. These all use ViewPageTemplateFiles in various different ways and so far I haven't been able to get all of them working at the same time. Hanno P.S. If you want to see my latest attempt at writing horrible code, this is the new __call__ method for Five's ViewPageTemplateFile: def __call__(self, *args, **keywords): instance = None # Ensure that the first argument is the instance if len(args) 0: instance, args = args[0], args[1:] if not IBrowserView.providedBy(instance): # The first arg is not the desired instance. Put the first # argument back into the list. args = list(args) args.insert(0, instance) instance = None # XXX! This isn't a particular nice way to get the instance. def _acquireInstance(): instance = None for i in range(2, 7): instance = sys._getframe(i).f_locals['self'] if IBrowserView.providedBy(instance): break return instance if instance is None: instance = _acquireInstance() # Copied the code from zope.app.pagetemplate as we need to pass on # the keywords which might contain one named 'instance', which would # conflict with the first required arg of that method.
