Subject: [PATCH 09/38] {lock,commit,rollback}_packed_refs(): add files_ref_store arguments
Date: Fri, 3 Jun 2016 23:03:44 +0200 [thread overview]
Message-ID: <54d13545f73cf6a00a2e3a5f89c3e4568b5c836b.1464983301.git.mhagger@alum.mit.edu> (raw)
In-Reply-To: <cover.1464983301.git.mhagger@alum.mit.edu>
These functions currently only work in the main repository, so add an
assert_main_repository() check to each function.
