Subject: [PATCH v21 04/19] refs.c: allow passing NULL to ref_transaction_free
Date: Mon, 14 Jul 2014 13:58:46 -0700	[thread overview]
Message-ID: <1405371541-32121-5-git-send-email-sahlberg@google.com> (raw)
In-Reply-To: <1405371541-32121-1-git-send-email-sahlberg@google.com>

Allow ref_transaction_free(NULL) as a no-op. This makes ref_transaction_free
easier to use and more similar to plain 'free'.

In particular, it lets us rollback unconditionally as part of cleanup code
after setting 'transaction = NULL' if a transaction has been committed or
rolled back already.
