Subject: [PATCH 16/39] object-store: add repository argument to foreach_alt_odb
Date: Wed, 30 Aug 2017 00:02:16 -0700
Message-ID: <20170830070216.GQ153983@aiede.mtv.corp.google.com> (raw)
In-Reply-To: <20170830064634.GA153983@aiede.mtv.corp.google.com>

From: Stefan Beller <sbeller@google.com>

Add a repository argument to allow foreach_alt_odb callers to be more
specific about which repository to handle. This is a small mechanical
change; it doesn't change the implementation to handle repositories
other than the_repository yet.

As with the previous commits, use a macro to catch callers passing a
repository other than the_repository at compile time.

While at it, move the declaration to object-store.h, where it should
be easier to find.
