Subject: [PATCH v2 31/36] odb-helper: add put_object_process()
Date: Mon, 19 Mar 2018 14:31:42 +0100	[thread overview]
Message-ID: <20180319133147.15413-32-chriscool@tuxfamily.org> (raw)
In-Reply-To: <20180319133147.15413-1-chriscool@tuxfamily.org>

This adds the infrastructure to send objects to a sub-process
handling the communication with an external odb.

For now we only handle sending raw blobs using the 'put_raw_obj'
instruction.
