Subject: [PATCH v2 4/8] fetch: add --repair option
Date: Thu, 24 Feb 2022 16:13:34 +0000 [thread overview]
Message-ID: <79c409d05422b02f7df9135af39cd0fa565f027a.1645719218.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1138.v2.git.1645719218.gitgitgadget@gmail.com>
From: Robert Coup <robert@coup.net.nz>
Teach fetch and transports the --repair option to force a full fetch
without negotiating common commits with the remote. Use when applying a
new partial clone filter to refetch all matching objects.
