Products.PurgeMissingObjectInterfaces

It's main purpose is being installed and run on an instance that has old, broken marker interface dependencies and being used to find and clear those dependencies. In particular this product was built to remove p4a (Plone 4 Artists) cruft when upgrading from Plone 3 to Plone 4. It should be noted that product has its own uninstallation procedure.

Project Description

Warning: This product is highly experimental, and created without deep knowledge/experience of the marker interfaces or ZODB machinery. It may start making modifications deep within the ZODB and interface machinery as soon as it is loaded.

It's main purpose is being installed and run on an instance that has old, broken marker interface dependencies and being used to find and clear those dependencies. In particular this product was built to remove p4a (Plone 4 Artists) cruft when upgrading from Plone 3 to Plone 4. It should be noted that product has its own uninstallation procedure.

To use, create an external method find, and give it the parameter string which is a comma-separated list of package/class names to look for and remove. In the case of Plone 4 Artists and its dependency dateable.chronos I used 'find?string=dateable,p4a'.

Portions copied from ZODB and zope.interface (under the ZPL). The rest is available under the GPL.
