Subject: [PATCH 21/27] upload-pack: support define shallow boundary by excluding revisions
Date: Fri, 10 Jun 2016 19:27:08 +0700 [thread overview]
Message-ID: <20160610122714.3341-22-pclouds@gmail.com> (raw)
In-Reply-To: <20160610122714.3341-1-pclouds@gmail.com>
This should allow the user to say "create a shallow clone of this branch
after version <some-tag>".
Short refs are accepted and expanded at the server side with expand_ref()
because we cannot expand (unknown) refs from the client side.
Like deepen-since, deepen-not cannot be used with deepen. But deepen-not
can be mixed with deepen-since. The result is exactly how you do the
command "git rev-list --since=... --not ref".
