From f0be0db13dbd2d96d2240374e0e9cb106bf6a614 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Mon, 7 Jan 2019 03:34:40 -0500 Subject: [PATCH] http: use struct object_id instead of bare sha1 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).
