Subject: [PATCH 07/39] sha1_file: add repository argument to alt_odb_usable
Date: Tue, 29 Aug 2017 23:56:31 -0700 [thread overview]
Message-ID: <20170830065631.GH153983@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 the alt_odb_usable caller to be
more specific about which repository to act on. This is a small
mechanical change; it doesn't change the implementation to handle
repositories other than the_repository yet.
Since the implementation does not yet work with other repositories,
use a wrapper macro to enforce that the caller passes in
the_repository as the first argument. It would be more appealing to
use BUILD_ASSERT_OR_ZERO to enforce this, but that doesn't work
because it requires a compile-time constant and common compilers like
gcc 4.8.4 do not consider "r == the_repository" a compile-time
constant.
