Subject: [PATCH 14/44] connect: detect algorithm when fetching refs
Date: Wed, 13 May 2020 00:53:54 +0000 [thread overview]
Message-ID: <20200513005424.81369-15-sandals@crustytoothpaste.net> (raw)
In-Reply-To: <20200513005424.81369-1-sandals@crustytoothpaste.net>
If we're fetching refs, detect the hash algorithm and parse the refs
using that algorithm.
