From: Brian Harring Date: Tue, 03 Jan 2012 13:46:03 GMT Subject: [PATCH] fix hang in git fetch if pointed at a 0 length bundle Message-ID: <20120103134603.GA31034@localhost> In-Reply-To: <20120103011352.GA13825@localhost> git-repo if interupted at the exact wrong time will generate zero length bundles- literal empty files. git-repo is wrong here, but git fetch shouldn't effectively spin loop if pointed at a zero length bundle.
