Subject: packfile: extract function to iterate through objects of a store
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=900d89743667e28db4de002427e950a270bfb734;p=thirdparty%2Fgit.git

packfile: extract function to iterate through objects of a store

In the next commit we're about to introduce a new function that knows to
iterate through objects of a given packfile store. Same as with the
equivalent function for loose objects, this new function will also be
agnostic of backends by using a `struct object_info`.

Prepare for this by extracting a new shared function to iterate through
a single packfile store.
