Subject: [PATCH v2 09/13] builtin/show-index: set the algorithm for object IDs
Date: Mon, 26 Apr 2021 01:02:57 +0000 [thread overview]
Message-ID: <20210426010301.1093562-10-sandals@crustytoothpaste.net> (raw)
In-Reply-To: <20210426010301.1093562-1-sandals@crustytoothpaste.net>
In most cases, when we load the hash of an object into a struct
object_id, we load it using one of the oid* or *_oid_hex functions.
However, for git show-index, we read it in directly using fread. As a
consequence, set the algorithm correctly so the objects can be used
correctly both now and in the future.
