Subject: [PATCH 06/15] Use the final_oid_fn to finalize hashing of object IDs
Date: Sat, 10 Apr 2021 15:21:31 +0000 [thread overview]
Message-ID: <20210410152140.3525040-7-sandals@crustytoothpaste.net> (raw)
In-Reply-To: <20210410152140.3525040-1-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.
