Subject: [PATCH 4/6] builtin/submodule--helper: store update_clone information in a struct
Date: Thu, 12 Jul 2018 12:47:52 -0700
Message-ID: <20180712194754.71979-5-sbeller@google.com> (raw)
In-Reply-To: <20180712194754.71979-1-sbeller@google.com>

The information that is printed for update_submodules in
'submodule--helper update-clone' and consumed by 'git submodule update'
is stored as a string per submodule. This made sense at the time of
48308681b07 (git submodule update: have a dedicated helper for cloning,
2016-02-29), but as we want to migrate the rest of the submodule update
into C, we're better off having access to the raw information in a helper
struct.
