Subject: [PATCH 18/31] refs.c: return immediately from _commit if the transaction has an error
Date: Wed, 14 May 2014 15:13:17 -0700 [thread overview]
Message-ID: <1400105610-21194-19-git-send-email-sahlberg@google.com> (raw)
In-Reply-To: <1400105610-21194-1-git-send-email-sahlberg@google.com>
If a previous transaction operation has failed and flagged a transaction
as having an error, then return immediately from commit and indicate failure.
Once we move checks from _commit to _update, _update will already have updated
the error string so the caller will know what failed. Thus we don't need to do
anything at all in _commit than return failure.
