Subject: [PATCH] Packfile-uris support excluding commit objects
Date: Fri,  7 May 2021 10:11:40 +0800	[thread overview]
Message-ID: <20210507021140.31372-1-dyroneteng@gmail.com> (raw)

On the server, more sophisticated means of excluding objects should be
supported, such as commit object. This commit introduces a new
configuration `uploadpack.commitpackfileuri` for this.

This patch only pack the commit object, not including the that commit
and all objects that it references. This work will be done in a further
patch recently.

Similarly, there are related documents that will be included in
subsequent patches.
