Subject: [PATCH v2 05/13] Use the final_oid_fn to finalize hashing of object IDs
Date: Mon, 26 Apr 2021 01:02:53 +0000	[thread overview]
Message-ID: <20210426010301.1093562-6-sandals@crustytoothpaste.net> (raw)
In-Reply-To: <20210426010301.1093562-1-sandals@crustytoothpaste.net>

When we're hashing a value which is going to be an object ID, we want to
zero-pad that value if necessary.  To do so, use the final_oid_fn
instead of the final_fn anytime we're going to create an object ID to
ensure we perform this operation.
