Subject: [PATCH v21 16/19] refs.c: make update_ref_write update a strbuf on failure
Date: Mon, 14 Jul 2014 13:58:58 -0700 [thread overview]
Message-ID: <1405371541-32121-17-git-send-email-sahlberg@google.com> (raw)
In-Reply-To: <1405371541-32121-1-git-send-email-sahlberg@google.com>
Change update_ref_write to also update an error strbuf on failure.
This makes the error available to ref_transaction_commit callers if the
transaction failed due to update_ref_sha1/write_ref_sha1 failures.
