[PATCH 15/16] packfile: refactor `get_all_packs()` to work on packfile store

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The `get_all_packs()` function prepares the packfile store and then
returns its packfiles. Refactor it to accept a packfile store instead of
a repository to clarify its scope.
