[PATCH 14/24] t5313: make test hash independent

From
brian m. carlson <sandals@crustytoothpaste.net>
Date
Jan 13, 2020, 12:38 UTC
Message-ID
<20200113123857.3684632-15-sandals@crustytoothpaste.net>
In-Reply-To
<20200113123857.3684632-1-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.
