From: Stefan Beller Date: Wed, 21 Jan 2015 01:20:55 GMT Subject: [PATCH] update-ref: Handle large transactions properly Message-ID: <1421803255-4037-1-git-send-email-sbeller@google.com> Test if we can do arbitrary large transactions. Currently this is a known bug that we cannot do large transactions, so document it at least in the test suite.
