Subject: [PATCH 5/9] add test for streaming corrupt blobs
Date: Mon, 25 Mar 2013 16:21:34 -0400 [thread overview]
Message-ID: <20130325202134.GE16019@sigill.intra.peff.net> (raw)
In-Reply-To: <20130325201427.GA15798@sigill.intra.peff.net>
We do not have many tests for handling corrupt objects. This
new test at least checks that we detect a byte error in a
corrupt blob object while streaming it out with cat-file.
