Re: problem w/recursive, submodules?

- I'm afraid that we're unable to expose the internal repo because of co. policies.  Other than wrapper scripts for our internal dev. environment, the only thing of note in the internal repo is the .gitmodules file, which consists of the following:

[submodule "staging"]
	path = src
	branch = staging
	url = https://github.com/nyfix/OpenMAMA-omnm.git

- We've found that the problem is avoided if we execute the following command *after* doing the recursive clone.  Not sure why this is necessary -- shouldn't the recursive clone handle that on its own?

git submodule update --remote --recursive

- It sounds like you're suggesting that we need to go into the submodule and manually checkout a specific commit?  Shouldn't the recursive clone pick up the HEAD of the submodule branch?

If it sounds like we don't quite understand what git is doing here, that's a fair statement ;-)  In particular, only the submodule branch is exposed to us, but it sounds like git internally stores the commit hash instead?

Thanks again for your help!

It's harder to understand the problem without being able to reproduce it. Do you have another example with public repositories?

If I understood it correctly, it looks to me that it's another case of one of the most common misconceptions about submodules: they always reference a specific commit instead of branch or the latest commit.

If you want your repository to reference other commit of your submodule, you'll need to manually change this and commit this change. One way you can do that:

cd <submodule> git checkout <new commit of the submodule> cd - git add <submodule> git commit

Note that you'll need to do that every time you want you want your repository to reference other commit of the submodule.
