Subject: [PATCH v4 7/8] maintenance: use 'incremental' strategy by default
Date: Thu, 15 Oct 2020 17:22:03 +0000	[thread overview]
Message-ID: <145c63ed8c61126dd19dbcdbe3fed81c32862f0a.1602782524.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.724.v4.git.1602782524.gitgitgadget@gmail.com>

From: Derrick Stolee <dstolee@microsoft.com>

The 'git maintenance (register|start)' subcommands add the current
repository to the global Git config so maintenance will operate on that
repository. It does not specify what maintenance should occur or how
often.

To make it simple for users to start background maintenance with a
recommended schedlue, update the 'maintenance.strategy' config option in
both the 'register' and 'start' subcommands. This allows users to
customize beyond the defaults using individual
'maintenance.<task>.schedule' options, but also the user can opt-out of
this strategy using 'maintenance.strategy=none'.
