Subject: [PATCH 1/3] archive: use packet_reader for communications
Date: Tue, 11 Sep 2018 22:35:17 -0700 [thread overview]
Message-ID: <20180912053519.31085-2-steadmon@google.com> (raw)
In-Reply-To: <20180912053519.31085-1-steadmon@google.com>
Using packet_reader will simplify version detection and capability
handling, which will make implementation of protocol v2 support in
git-archive easier.
