Subject: [PATCH 03/11] http: use struct object_id instead of bare sha1
Date: Mon, 7 Jan 2019 03:34:40 -0500
Message-ID: <20190107083440.GC29431@sigill.intra.peff.net> (raw)
In-Reply-To: <20190107083150.GC21362@sigill.intra.peff.net>

The dumb-http walker code still passes around and stores object ids as
"unsigned char *sha1". Let's modernize it.

There's probably still more work to be done to handle dumb-http fetches
with a new, larger hash. But that can wait; this is enough that we can
now convert some of the low-level object routines that we call into from
here (and in fact, some of the "oid.hash" references added here will be
further improved in the next patch).
