Summary of Changes

Hello @tvalentyn, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request refactors the Python SDK wheel identification and installation process within the container boot sequence. By eliminating the need for explicit, version-dependent wheel specification validation, the system now uses a more direct and flexible approach to locate the correct SDK wheel. This change reduces code complexity and improves the maintainability of the container's setup logic.

Highlights

• Simplified Wheel Validation: The logic for validating and identifying Python wheels, specifically for the Apache Beam SDK, has been significantly simplified by removing version-specific checks.
• Removed Unnecessary Code: The setupAcceptableWheelSpecs function, the acceptableWhlSpecs global variable, and the regexp import, all related to the previous wheel validation, have been removed.
• Streamlined SDK Installation: The installSdk and findBeamSdkWhl functions were updated to reflect the simplified wheel identification, reducing their parameter lists and internal complexity.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

Changelog

• sdks/python/container/boot.go
  • Removed the regexp import.
  • Eliminated the acceptableWhlSpecs global variable.
  • Deleted the setupAcceptableWheelSpecs function, which was responsible for determining acceptable wheel specifications.
  • Updated the installSetupPackages function to remove calls to the setupAcceptableWheelSpecs function and simplify the arguments passed to installSdk.
• sdks/python/container/piputil.go
  • Modified the findBeamSdkWhl function signature to remove the acceptableWhlSpecs parameter and simplified its internal logic to identify wheels based on a .whl suffix.
  • Adjusted the installSdk function signature and its internal call to findBeamSdkWhl to no longer require the acceptableWhlSpecs parameter.

Tested that any wheel name gets picked up:

Could this lead to us getting the wheel for the wrong python version? If yes, should we at least keep that piece of the check? (e.g. check if it contains cp313)

[tvalentyn]

Yes, it is possible if there is more than 1 wheel staged.
