Subject: [PATCH v4 05/12] pack-bitmap: uninteresting oid can be outside bitmapped packfile
Date: Wed, 18 Dec 2019 12:25:40 +0100	[thread overview]
Message-ID: <20191218112547.4974-6-chriscool@tuxfamily.org> (raw)
In-Reply-To: <20191218112547.4974-1-chriscool@tuxfamily.org>

From: Jeff King <peff@peff.net>

bitmap_has_oid_in_uninteresting() only used bitmap_position_packfile(),
not bitmap_position(). So it wouldn't find objects which weren't in the
bitmapped packfile (i.e., ones where we extended the bitmap to handle
loose objects, or objects in other packs).

As we could reuse a delta against such an object it is suboptimal not
to use bitmap_position(), so let's use it instead of
bitmap_position_packfile().
