[PATCH 27/38] t5308: make test work with SHA-256

From
brian m. carlson <sandals@crustytoothpaste.net>
Date
Jul 10, 2020, 02:47 UTC
Message-ID
<20200710024728.3100527-28-sandals@crustytoothpaste.net>
In-Reply-To
<20200710024728.3100527-1-sandals@crustytoothpaste.net>

This test needs multiple object IDs that have the same first byte. Update the pack test code to generate a suitable packed value for SHA-256. Update the test to use this value when using SHA-256.
