Subject: [PATCH v2 32/36] sha1_file: convert read_object_with_reference to object_id
Date: Sun, 25 Feb 2018 21:12:08 +0000 [thread overview]
Message-ID: <20180225211212.477570-33-sandals@crustytoothpaste.net> (raw)
In-Reply-To: <20180225211212.477570-1-sandals@crustytoothpaste.net>
Convert read_object_with_reference to take pointers to struct object_id.
Update the internals of the function accordingly.
