I'm confused, push doesn't know the "--recurse-submodules" option at all yet while pull only does a deep fetch when it is given, the submodule work trees are not updated to the merge result right now. >> And I miss to see how >> floating would help when the tips of some submodules are not ready to >> work with other submodules tips ... > > By project policy, for any branch, all submodules' tips of the > same-named branch should be interoperable. The CI server looks after > this, as much as he can. We do the same thing on our CI server, but it can only test some combinations (even though that tends to show most problems pretty early). But in the end every superproject is responsible to use a working set of submodule commits, and I would rather bet on a combination the CI server tested than on what happens to be on the current tips. > I think of branch names as sticky notes (extra-lightweight tags, > sometimes).

We also add a branch in submodules every time a superproject needs to move away from the submodules master (so the commits won't get lost by accident). >>> But not all my developers are git-gurus yet, and they sometimes mess >>> up their ad hoc scripts or miss important changes they forgot to push >>> in one submodule or another. >> >> Sure, even though current git should help you some by showing changes >> in the submodules. > > Real newbies may not even remember to use 'git status' strategically.

I think we can make working with submodule much easier than it is now, the next step being updating all submodule work trees as git updates the superproject's work tree. Even though I suspect that in the long run submodules will always be a bit more complicated than having everything in one repository, I'm confident that will be by far outweighed by the advantages they bring. -- 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
