Subject: [PATCH v2 28/36] odb-helper: add init_object_process()
Date: Mon, 19 Mar 2018 14:31:39 +0100	[thread overview]
Message-ID: <20180319133147.15413-29-chriscool@tuxfamily.org> (raw)
In-Reply-To: <20180319133147.15413-1-chriscool@tuxfamily.org>

This adds the infrastructure to launch and use long running
sub-processes as external odb helpers.

For now only the 'init' and 'get_direct' capabilities are
supported with sub-processes.
