Subject: [PATCH v2 35/39] t: allow testing different hash algorithms via environment
Date: Mon, 13 Jul 2020 02:49:05 +0000	[thread overview]
Message-ID: <20200713024909.3714837-36-sandals@crustytoothpaste.net> (raw)
In-Reply-To: <20200713024909.3714837-1-sandals@crustytoothpaste.net>

To allow developers to run the testsuite with a different algorithm than
the default, provide an environment variable, GIT_TEST_DEFAULT_HASH, to
specify the algorithm to use. Compute the fixed constants using
test_oid. Move the constant initialization down below the point where
test-lib-functions.sh is loaded so the functions are defined.
