There is one big distinction. My patch for commit doesn't add any new
problems. It just adds the --ignore-submodules argument, which is easy
to implement and no unclear behavior decisions are needed.
You are right that when specifying ignored submodules on commit's
command line, there is the same problem as with git add. However, it's
already there anyway. I don't feel in position to solve it, I'd just
like to have "git commit --ignore-submodules=none".
With git add however, changing it to honor settings from .gitmodules
would change behavior people might be used to, so I would be afraid to
do that. Btw add also has the problem already, but only if somebody
configures the submodule's ignore setting in .git/config, rather than
.gitmodules. I don't know how much real use case that is.
As I see it, there are now these rather easy possibilities (sorted
from the easiest):
1) Just teach commit the --ignore-submodules argument, as I proposed.
2) Teach both add and commit to --ignore-submodules, but dont add that
problematic gitmodules_config() in add.c.
3) Teach both add and commit to --ignore-submodules, and also let add
honor settings from .gitmodules, to make it more consistent with other
commands. And, make add --force imply --ignore-submodules=none.
I like both 1) and 2). I don't like 3), the problem of add with
submodules' ignore setting is a bug IMHO (ignore=all in .git/config
causes strange behavior, while ignore=all in .gitmodules is ignored),
but not directly related to the --ignore-submodules param, and should
be solved separately.
