Subject: [PATCH 03/35] object: add repository argument to lookup_unknown_object
Date: Tue, 29 May 2018 17:47:38 -0700	[thread overview]
Message-ID: <20180530004810.30076-4-sbeller@google.com> (raw)
In-Reply-To: <20180530004810.30076-1-sbeller@google.com>

From: Jonathan Nieder <jrnieder@gmail.com>

Add a repository argument to allow callers of lookup_unknown_object 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.

The included coccinelle semantic patch will adapt any new callers in
the diff produced by `make coccicheck`.
