mip: package installation using GitLab URLs for repos in subgroups

micropython/mip/mip/init.py の 63 行目付近にある _rewrite_url 関数から始め、GitLab のサブグループ URL を使って失敗する mpremote mip install コマンドを再現します。動作する raw URL および既存の GitHub/GitLab 形式と比較します。サブグループのパッケージ URL と依存関係 URL が、現在の URL 処理を壊すことなく正しく解決されれば完了です。

This is more of an awareness piece and something to trigger a discussion. There is also the possibility that I am wrong and the installation process is working as intended.

I'm currently developing MicroPython packages on GitLab, which sit inside a 'Libraries' subgroup, which is inside a parent 'MicroPython IoT Projects' group.

Due to the way that the mip _rewrite_url function parses GitLab and GitHub URLs, the assumption is made that the first component after splitting the URL, is the org and the second is the repository slug, which doesn't account for subgroups.

https://github.com/micropython/micropython-lib/blob/96bd01ec047923c15bf936d2f77043968745542d/micropython/mip/mip/__init__.py#L63

As a result, I had to change the way I reference my packages and package extension urls and deps in the package.json files. My network-utils 'package.json' has to have the following structure:

{
    "urls": [
        ["network_utils/__init__.py", "https://gitlab.com/micropython-iot-projects/libraries/micropython-network-utils/-/raw/HEAD/network-utils/network_utils/__init__.py"]
    ],
    "deps": [
        ["logging", "latest"],
        ["github:josverl/micropython-stubs/mip/typing.mpy", "main"],
        ["github:josverl/micropython-stubs/mip/typing_extensions.mpy", "main"]
    ],
    "version": "0.0.1"
}

In order to install network-utils with mpremote, I would have to use the following command:

mpremote mip install https://gitlab.com/micropython-iot-projects/libraries/micropython-network-utils/-/raw/HEAD/network-utils/package.json

The command below will not work, resulting in a 403 error:

mpremote mip install gitlab:micropython-iot-projects/libraries/micropython-network-utils/network-utils/package.json

The network-utils-mqtt extension package, which requires network-utils, had to have its package.json written like so:

{
    "urls": [
        ["network_utils/mqtt.py", "https://gitlab.com/micropython-iot-projects/libraries/micropython-network-utils/-/raw/HEAD/network-utils-mqtt/network_utils/mqtt.py"]
    ],
    "deps": [
        ["https://gitlab.com/micropython-iot-projects/libraries/micropython-network-utils/-/raw/HEAD/network-utils/",  "develop"]
    ],
    "version": "0.0.1"
}

The URL for the deps, which is the network-utils package this one extends, had to be rewritten so that the package.json could be found correctly.
