Subject: [PATCH 5/5] rev-list: handle missing tree objects properly
Date: Thu,  9 Aug 2018 15:45:04 -0700	[thread overview]
Message-ID: <54d827e7c0dc757451fa10f5bd0752e1e3356281.1533854545.git.matvore@google.com> (raw)
In-Reply-To: <cover.1533854545.git.matvore@google.com>

Previously, we assumed only blob objects could be missing. This patch
makes rev-list handle missing trees like missing blobs. A missing tree
will cause an error if --missing indicates an error should be caused,
and the hash is printed even if the tree is missing.
