Subject: [PATCH 08/17] object: convert internal hash_obj() to object_id
Date: Thu, 20 Jun 2019 03:41:17 -0400	[thread overview]
Message-ID: <20190620074117.GH3713@sigill.intra.peff.net> (raw)
In-Reply-To: <20190620073952.GA1539@sigill.intra.peff.net>

Now that lookup_object() has an object_id, we can consistently pass that
around instead of a raw sha1. We still convert to a hash to pass to
sha1hash(), but the goal is for that to go away shortly.
