Subject: [PATCH v2 13/22] t5313: make test hash independent
Date: Sat, 25 Jan 2020 23:00:19 +0000	[thread overview]
Message-ID: <20200125230035.136348-14-sandals@crustytoothpaste.net> (raw)
In-Reply-To: <20200125230035.136348-1-sandals@crustytoothpaste.net>

Make this test hash independent by computing the length of the object
offsets and looking up values which will hash to object IDs with the
right properties.
