Subject: [PATCH v5 08/13] commit-graph: add core.commitGraph setting
Date: Mon, 26 Feb 2018 21:33:02 -0500	[thread overview]
Message-ID: <1519698787-190494-9-git-send-email-dstolee@microsoft.com> (raw)
In-Reply-To: <1519698787-190494-1-git-send-email-dstolee@microsoft.com>

The commit graph feature is controlled by the new core.commitGraph config
setting. This defaults to 0, so the feature is opt-in.

The intention of core.commitGraph is that a user can always stop checking
for or parsing commit graph files if core.commitGraph=0.
