Subject: [PATCH v4 03/11] promisor-remote: implement promisor_remote_get_direct()
Date: Mon,  1 Apr 2019 18:40:37 +0200	[thread overview]
Message-ID: <20190401164045.17328-4-chriscool@tuxfamily.org> (raw)
In-Reply-To: <20190401164045.17328-1-chriscool@tuxfamily.org>

From: Christian Couder <christian.couder@gmail.com>

This is implemented for now by calling fetch_objects(). It fetches
from all the promisor remotes.
