Subject: [PATCH v6 26/40] odb-helper: add init_object_process()
Date: Sat, 16 Sep 2017 10:07:17 +0200 [thread overview]
Message-ID: <20170916080731.13925-27-chriscool@tuxfamily.org> (raw)
In-Reply-To: <20170916080731.13925-1-chriscool@tuxfamily.org>
From: Ben Peart <benpeart@microsoft.com>
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.
