Subject: [PATCH 1/6] Protect peel_ref fallback case from NULL parse_object result
Date: Sun, 24 Feb 2008 03:07:19 -0500 [thread overview]
Message-ID: <20080224080719.GA22587@spearce.org> (raw)
If the SHA-1 we are requesting the object for does not exist in
the object database we get a NULL back. Accessing the type from
that is not likely to succeed on any system.
