How to correctly require a specific commit in Composer so that it would be available for dependent packages?

Question

I have a library foo/foo-lib which requires a specific commit from GitHub:

{
    \"name\": \"foo/foo-lib\",
    \"repositories\": [

You'll have to explicitly require the Gaufrette library at that hash, with a dev flag, in both your library and your application. Something like this should work in the application composer.json:

{
    "name": "bar/bar-app",
    "repositories": [
        {
            "type": "vcs",
            "url": "ssh://git.example.com/foo-lib"
        }
    ],
    "require-dev": {
        "foo/foo-lib": "dev-master",
        "knplabs/gaufrette": "dev-master#2633721877cae79ad461f3ca06f3f77fb4fce02e"
    }
}

From the documentation:

If one of your dependencies has a dependency on an unstable package you need to explicitly require it as well, along with its sufficient stability flag.

The documentation also suggests that you'll need to include the repository for Gaufrette in your bar/bar-app Composer file, though it sounds like this wasn't necessary in this case. I'm not sure why.
