Subject: [PATCH 04/23] object-store: prepare read_object_file to deal with any repo
Date: Fri, 14 Dec 2018 16:09:23 -0800
Message-ID: <20181215000942.46033-5-sbeller@google.com> (raw)
In-Reply-To: <20181215000942.46033-1-sbeller@google.com>

As read_object_file is a widely used function (which is also regularly used
in new code in flight between master..pu), changing its signature is painful
is hard, as other series in flight rely on the original signature. It would
burden the maintainer if we'd just change the signature.

Introduce repo_read_object_file which takes the repository argument, and
hide the original read_object_file as a macro behind
NO_THE_REPOSITORY_COMPATIBILITY_MACROS, similar to
e675765235 (diff.c: remove implicit dependency on the_index, 2018-09-21)

Add a coccinelle patch to convert existing callers, but do not apply
the resulting patch to keep the diff of this patch small.
