From 14228447c9ce664a4e9c31ba10344ec5e4ea4ba5 Mon Sep 17 00:00:00 2001 From: "brian m. carlson" Date: Mon, 26 Apr 2021 01:02:56 +0000 Subject: hash: provide per-algorithm null OIDs Up until recently, object IDs did not have an algorithm member, only a hash. Consequently, it was possible to share one null (all-zeros) object ID among all hash algorithms. Now that we're going to be handling objects from multiple hash algorithms, it's important to make sure that all object IDs have a correct algorithm field. Introduce a per-algorithm null OID, and add it to struct hash_algo. Introduce a wrapper function as well, and use it everywhere we used to use the null_oid constant.
