Subject: [PATCH 07/15] t4011: abstract away SHA-1-specific constants
Date: Sat,  5 Oct 2019 21:12:01 +0000	[thread overview]
Message-ID: <20191005211209.18237-8-sandals@crustytoothpaste.net> (raw)
In-Reply-To: <20191005211209.18237-1-sandals@crustytoothpaste.net>

Adjust the test so that it computes variables for object IDs instead of
using hard-coded hashes.
