feat: Add GitHub Release workflow for Python SDK

[wanlin31]

This PR introduces a new release process for the Python SDK, distributing it as a wheel file attached to GitHub Releases instead of publishing it to PyPI. This approach allows us to version and distribute the SDK without treating it as a standalone product.

Python release process

• New Versioning Scheme: Python SDK tags will now follow a composite format, sdks/python/v[SDK_VERSION]-core.[CORE_VERSION], to link each SDK release directly to the version of the core Go executable it wraps.

  • Core Go Executable Tag: v[CORE_VERSION] (Example: v0.2.8)
  • Python SDK Tag: sdks/python/v[SDK_VERSION]-core.[CORE_VERSION] (Example: sdks/python/v0.1.0-core.0.2.8)

• Automated Release Workflow: A new GitHub Actions workflow (release-python-sdk.yml) triggers automatically when a tag matching sdks/python/v* is pushed.

  • The workflow builds the Python wheel (.whl).
  • It creates a new draft GitHub Release.
  • The built wheel is attached as a release asset.

And we then set up the a release workflow that looks for tag that start with sdks/python/v, and build the artifact attach to a draft release.

Usage

Users can now install a specific version of the Python SDK directly from GitHub Releases using

pip install https://github.com/google/test-server/releases/download/[TAG]/[WHEEL_FILE_NAME].whl

Example

pip install https://github.com/google/test-server/releases/download/sdks/python/v0.1.0-core.0.2.7/test_server_sdk-0.1.0-py3-none-any.whl 

Test:

Since the we used a fork method, the build actually trigged on my fork. Once this is merged, the tag will trigger the release on upstream.

Create a release

git tag sdks/python/v0.1.0-core.0.2.7-test
git push origin sdks/python/v0.1.0-core.0.2.7-test

Successfully triggered the build on pushing the tag

Build finish successfully

Created draft release

Clean up the test

git push --delete origin sdks/python/v0.1.0-core.0.2.7-test
git tag -d sdks/python/v0.1.0-core.0.2.7-test

Would we be able to do something similar for other languages?

Is there a command for this?

[wanlin31]

I think npm and pip support this most seamlessly, golang is more on the fetch the code directly, dotnet and java may need some workaround, they might need to download the artifact and install from local.

As of now JS and Dotnet has already been published, this exercises is trying to not avoid publishing the python test-server-sdk itself as a product.

[Annhiluc]

Ack. For the 'publish the release' step is there a command for this?

[wanlin31]

When you click into the draft release, it looks like this

We can make the release public by clicking the publish button on the bottom.
