Subject: [PATCH 5/5] read_loose_refs(): read refs using resolve_ref_recursively()
Date: Thu, 9 Feb 2017 14:27:02 +0100 [thread overview]
Message-ID: <024d6b2e5ca1ffa876c2911e6d9d0bb4f6091730.1486629195.git.mhagger@alum.mit.edu> (raw)
In-Reply-To: <cover.1486629195.git.mhagger@alum.mit.edu>
There is no need to call read_ref_full() or resolve_gitlink_ref() from
read_loose_refs(), because we already have a ref_store object in hand.
So we can call resolve_ref_recursively() ourselves. Happily, this
unifies the code for the submodule vs. non-submodule cases.
This requires resolve_ref_recursively() to be exposed to the refs
subsystem, though not to non-refs code.
