Subject: [PATCH v3 8/8] fetch-pack: implement ref-in-want
Date: Wed, 20 Jun 2018 14:32:35 -0700 [thread overview]
Message-ID: <20180620213235.10952-9-bmwill@google.com> (raw)
In-Reply-To: <20180620213235.10952-1-bmwill@google.com>
Implement ref-in-want on the client side so that when a server supports
the "ref-in-want" feature, a client will send "want-ref" lines for each
reference the client wants to fetch.
