Subject: [PATCH v5 08/14] partial-clone: define partial clone settings in config
Date: Tue, 21 Nov 2017 21:15:22 +0000 [thread overview]
Message-ID: <20171121211528.21891-9-git@jeffhostetler.com> (raw)
In-Reply-To: <20171121211528.21891-1-git@jeffhostetler.com>
From: Jeff Hostetler <jeffhost@microsoft.com>
Create get and set routines for "partial clone" config settings.
These will be used in a future commit by clone and fetch to
remember the promisor remote and the default filter-spec.
Signed-off-by: Jeff Hostetler <jeffhost@microsoft.com>
