Subject: [PATCH 08/31] refs.c: only write reflog update if msg is non-NULL
Date: Wed, 14 May 2014 15:13:07 -0700 [thread overview]
Message-ID: <1400105610-21194-9-git-send-email-sahlberg@google.com> (raw)
In-Reply-To: <1400105610-21194-1-git-send-email-sahlberg@google.com>
When performing a reflog transaction update, only write to the reflog iff
msg is non-NULL. This can then be combined with REFLOG_TRUNCATE to perform
an update that only truncates but does not write.
