Subject: [PATCH v3 5/5] upload-pack: make uploadpack.packObjectsHook protected
Date: Fri, 27 May 2022 21:09:21 +0000	[thread overview]
Message-ID: <e25d5907cd1e3894f19ffbfb3310175fd660563b.1653685761.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1261.v3.git.git.1653685761.gitgitgadget@gmail.com>

From: Glen Choo <chooglen@google.com>

Now that protected config includes "-c", "uploadpack.packObjectsHook"
behaves identically to a 'Protected config only' variable. Refactor it
to use git_protected_config() and mark it 'Protected config only'.
