Subject: [PATCH v2 08/15] t4015: abstract away SHA-1-specific constants
Date: Mon, 28 Oct 2019 00:59:00 +0000	[thread overview]
Message-ID: <20191028005907.24985-9-sandals@crustytoothpaste.net> (raw)
In-Reply-To: <20191028005907.24985-1-sandals@crustytoothpaste.net>

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