Subject: [PATCH v3 08/39] t6500: specify test values for SHA-256
Date: Thu, 23 Jul 2020 01:09:12 +0000 [thread overview]
Message-ID: <20200723010943.2329634-9-sandals@crustytoothpaste.net> (raw)
In-Reply-To: <20200723010943.2329634-1-sandals@crustytoothpaste.net>
In this test, we want to produce several blobs whose first two hex
characters are "17", since we look at this object directory as a proxy
for how many loose objects there are before we need to GC. Use
test_oid_cache to specify strings that will hash to the right values
when turned into blobs.
