You could probably work directly with the pickles way faster than activating every object in a large site: look at the 'fsdump' script for clues. You could also write a stand-alone python routine to access the zodb (.fs file) directly (should be faster than running a script through a running zope instance and maybe easier than working with pickles).

On second thought I guess my hidden assumption was that context.all_meta_types() would give me the best list of installed products to compare against, and thus I would need the actual meta_type string. On examining the results of the first run of my db-based script, I'm not so sure. It's after all just some strings.. Perhaps I ought to rephrase that as a question :) Can I rely on context.all_meta_types() being complete, or could a product have installed objects that would not be in that list? Is there some other, more reliable way to link an object to it's product?

[Zope] Finding unused products
Quick question before I reinvent. Is there some established way of finding products which have no instances in zodb, and can be safely removed?
