Subject: [PATCH v1 03/11] remote-odb: implement remote_odb_get_direct()
Date: Sat, 23 Jun 2018 14:18:40 +0200	[thread overview]
Message-ID: <20180623121846.19750-4-chriscool@tuxfamily.org> (raw)
In-Reply-To: <20180623121846.19750-1-chriscool@tuxfamily.org>

This is implemented only in the promisor remote mode
for now by calling fetch_object().
