Subject: [PATCH v2] add--interactive: ignore submodule changes except HEAD
Date: Sat, 13 Jan 2018 19:10:38 +0700
Message-ID: <20180113121038.26984-1-pclouds@gmail.com> (raw)
In-Reply-To: <20180110110643.21465-1-pclouds@gmail.com>

For 'add -i' and 'add -p', the only action we can take on a dirty
submodule entry is update the index with a new value from its HEAD. The
content changes inside (from its own index, untracked files...) do not
matter, at least until 'git add -i' learns about launching a new
interactive add session inside a submodule.

Ignore all other submodules changes except HEAD. This reduces the number
of entries the user has to check through in 'git add -i', and the number
of 'no' they have to answer to 'git add -p' when dirty submodules are
present.

 v2 now has some tests. The commit message is rephrased a bit.
