[Zope-dev] Proposal: Merge philikon-aq branch into Zope trunk
Hi. I'd like to propose to merge the philikon-aq branch into Zope trunk aka Zope 2.12. Scope: For those unfamiliar with the branch, it makes Acquisition aware of __parent__ pointers. This makes it unnecessary to use Acquisition mixin's for Zope 3 code to use them in Zope 2 code. The security machinery of Zope 2 will still be able to work as expected. Status: All tests in the Zope itself pass. New tests have been written for all edge cases found during the development of the branch. As a real world exposure Plone has been used to test the branch. All tests in Plone except one edge-case of a monkey-patch loaded package still pass. Plone in current versions make heavy use of Zope 3 and Five technologies inside Zope 2, so I see this as a very good indicator for the readiness of the branch. The one edge-case is something which needs to be fixed in Plone, as it doesn't make use of any official API. Risks: Using Zope 3 code inside Zope 2 has lead to various 'inventive solutions' to work around problems. Some of these have not used official API's. It is possible that some of those might need to be adjusted. Adjusting them should be straight forward in most cases and mostly consist of removing the hackish workarounds. The second problem that might arise, is that the implicit assumption that every object inside Zope 2 inherits from Acquisition base classes no longer holds. Code that relies on the various aq_* attributes to be there need to be adjusted to use the Acquisition methods instead. This change is trivial to do and doesn't need to be done at first. It only needs to be done when you want to allow direct Zope 3 code in your application. As part of the branch all code in Zope 2 itself have been adjusted to use the aq_* methods. Timeline: I would like to do the merge as soon as possible, so people can easily test it against all their applications and report back problems. Merging it into Zope trunk will get it into the Zope 2.12 release which is at this point not scheduled yet, but is unlikely to get a release before early 2009.

The second problem that might arise, is that the implicit assumption
that every object inside Zope 2 inherits from Acquisition base classes
no longer holds. Code that relies on the various aq_* attributes to be

The major downside here is that restricted code doesn't have access to
the required functions ('aq_inner', 'aq_parent', 'aq_acquire'), and
hence use the attributes. ('aq_base' should not be allowewd at all, as
it strips away security context).
There are probably thousands (or even tens of thousands) of templates
and scripts in the wild which use these attributes. I don't think we
can break them in a single release: we need to deprecate them first
(with suitalbe logging output), and maybe even provide
'__parent__'-aware workarounds / fallbacks in their implementations.
This
change is trivial to do and doesn't need to be done at first. It only
needs to be done when you want to allow direct Zope 3 code in your
application. As part of the branch all code in Zope 2 itself have been
