Subject: [PATCH v2 4/9] pack-bitmap: don't rely on bitmap_git->reuse_objects
Date: Sat, 19 Oct 2019 12:35:26 +0200 [thread overview]
Message-ID: <20191019103531.23274-5-chriscool@tuxfamily.org> (raw)
In-Reply-To: <20191019103531.23274-1-chriscool@tuxfamily.org>
From: Jeff King <peff@peff.net>
We will no longer compute bitmap_git->reuse_objects in a
following commit, so we cannot rely on it anymore to
terminate the loop early; we have to iterate to the end.
