The prerequisites must exist and be well connected in the target repo before the pack file is indexed: presumably, the reference objects all exist if the checks hold, or there is a logic flaw in the thin-pack generation. If the prereq test is removed, then avoiding a thin pack might allow the pack file to be applied to a repo that held only the prereqs for a single head out of many in the bundle, but there is no info for the user to understand how or when to do this and I don't really think that is a good practice to encourage. I suggest waiting for a well defined use-case that really demands being able to apply only part of a pack file before implementing. > Also, as mentioned above, I think that we have to check that "git rev-list > --objects --not --all" does not result in missing objects. > This is certainly a good safety check: even though the prereqs are satisfied and all *should* be ok, some error might still exist and it is better to be safe. > Ciao, > Dscho >
