Removing that option results in the expected behaviour. Yes, removing it will help your use case but break others. The reason for that is that because submodules are not updated during a rebase it doesn't make sense to compare their HEAD to what is recorded in the superproject, as that might have been changed by an earlier commit. And as the submodules HEAD hasn't been updated back then, it is stale and will always show up as modified (even if it wasn't). > I can understand not updating submodules while running the rebase, but I expected that having resolved a conflict and added my change to the index it would be applied by `git rebase --continue`, as indeed it is if there happen to be other (non-submodule) changes in the same commit. The irony is that you would have to update submodules (or at least their HEAD and use "--ignore-submodules=dirty") while running rebase to make that work in all cases ;-) But just updating the HEAD would be dangerous as you would have to be very careful to restore the submodules HEAD after the rebase, or the submodule's work tree will be out of sync. I suspect in the long run a rebase should, e.g. when invoked with --recurse-submodules, update the submodules too and won't use the --ignore-submodule option for diff anymore ... then everything should Just Work. But until that happens, I don't see a solution for your problem. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
