Subject: [PATCH v3 33/39] Enable SHA-256 support by default
Date: Thu, 23 Jul 2020 01:09:37 +0000 [thread overview]
Message-ID: <20200723010943.2329634-34-sandals@crustytoothpaste.net> (raw)
In-Reply-To: <20200723010943.2329634-1-sandals@crustytoothpaste.net>
Now that the we have a complete SHA-256 implementation in Git, let's
enable it so people can use it. Remove the ENABLE_SHA256 define
constant everywhere it's used. Add tests for initializing a repository
with SHA-256.
