Cleanup after migration from Plone 2.5 to 3
Products.Plone3Cleaners: cleanup after migration from Plone 2.5 to 3
This package is a collection of browser views that you might need when migrating from Plone 2.5 to Plone 3. And actually, some of these can be handy also when not migration, like removing portal_factory items from the portal_catalog.
Add this package to the eggs of your buildout; no install inside Plone is needed.
Five local sites
Local sites from Products.Five have changed a lot since the Plone 2.5 days. They need migration. Products.Five offers the manage_site.html page; just add this to the url of your local site and click the ‘Migrate to Five.component’ button. You should try that first, but in my experience that usually does not work.
Note that a default Plone 2.5 Site does not use localsites, so if you have them, then they are from a third party product. If you see an error like this in the logs when looking at your Plone 3 Site you have a problem:
2009-06-23 12:30:17 ERROR ZPublisher BeforeTraverse: Error while invoking hook: "__local_site_hook__" Traceback (most recent call last): File "/home/maurits/zopes/Zope-2.10.7-final-py2.4/lib/python/ZPublisher/BeforeTraverse.py", line 145, in __call__ meth(*(container, request, None)[:args]) AttributeError: __call__
We have two browser views that help in fixing this:
- @@find_local_sites: add this to the url of your Plone Site or of your Zope root. Click the submit button to find all objects with a problematic local site hook. Your zope instance log will have some details and the page will display links to the objects that need fixing. The links will point to our second browser view:
- @@update_local_site: add this to the url of an object with an old local site hook that needs fixing. Likely, calling this will give that same AttributeError once or twice, but you can ignore that as you are about to fix it : click the ‘Migrate to Five.component’ button.
The object that had the old local site hook may need some fixes in the python code as well. Ask the developer of the product that this object is from. Note that a local site hook is not always the right solution; and this migration is not always enough. In a client project I got rid of one hook and used a simple attribute instead; a second hook worked fine after the above migration; a third hook needed a different migration.
portal_factory in portal_catalog
You have seen this: you write a catalog query, on one of the brains you do a brain.getObject() and this fails because the object was wrongly added to the catalog while being created and it was not cleaned up. Clean it up with @@factory_cleanup. You can choose to remove those portal_factory brains or remove any brain where getObject() fails. For various reasons this may find less or more items; certainly it takes a lot longer.
