Hmm, to me an empty directory is the natural representation of an unpopulated submodule, but I see why that made it hard for your maintainer to notice the fact that the submodule was uninitialized. I suspect changing an unpopulated submodule to be represented by a file will surprise quite some users (some of which will probably come up with perfectly valid use cases such a change will break). What about the following: Today's Git completely ignores empty submodule directories, but I think that when the recursive checkout support is there, the "submodule.autoupdate" flag - which I believe should control that behavior - could also make those empty submodule directories show up in "git status" as being unpopulated (after all they are configured to be updated automatically, so not having them populated is something Git should show). Would something like this have helped here? Until then I can only propose to establish a best practice of using "git clone --recurse-submodules" in these situations to avoid the problem you described. -- 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
