This series lets you query the delta base for a particular object (or set of objects), like: $ git rev-list --objects --all | git cat-file --batch-check='%(objectname) %(deltabase) %(rest)' The only other way I know of to get this information is using verify-pack (or index-pack), which is much slower (and less convenient to parse). I needed this recently to write tests for another (not yet published) series. But I think it stands on its own as a debugging / introspection tool.
