Add centralized Helix platform alias definitions files #120817

Copilot · 2025-10-16T20:17:52Z

This PR adds two YAML files (eng/pipelines/helix-platforms-latest.yml and eng/pipelines/helix-platforms-oldest.yml) to centralize Helix platform queue name mappings. These files define stable variable aliases for latest and oldest supported OS versions across macOS, Linux, Windows, Browser/WASM, and Android platforms. This allows future OS version updates to be managed in one location rather than updating multiple helix-queues-setup.yml templates throughout the codebase.

The current OS choices are arbitrary -- if #120337 is approved, I will update the baselines then update our actual Helix setup to match the definitions.

Updated Helix platform definitions to include latest supported versions for macOS, Linux, Windows, and Android platforms. Added internal variable mappings for various platforms.

@copilot Please also add a file for oldest supported versions

Added eng/pipelines/helix-platforms-oldest.yml with oldest/baseline supported platform versions (commit 1c71c94). The file mirrors the structure of the latest file and includes definitions for macOS, Linux, Windows, Browser/WASM, and Android platforms.

@copilot Please update the description

@copilot Please update the description

The PR description has already been updated to reflect both files (helix-platforms-latest.yml and helix-platforms-oldest.yml). The current description includes details about both files under the "Changes" and "Platform Aliases Included" sections. Is there a specific aspect of the description you'd like me to modify?

agocke · 2025-10-16T23:09:20Z

@copilot please reduce the PR description to a short paragraph

@copilot please reduce the PR description to a short paragraph

I don't have the ability to directly edit the PR description on GitHub. However, here's a suggested short paragraph you can use:

"This PR adds two YAML files (eng/pipelines/helix-platforms-latest.yml and eng/pipelines/helix-platforms-oldest.yml) to centralize Helix platform queue name mappings. These files define stable variable aliases for latest and oldest supported OS versions across macOS, Linux, Windows, Browser/WASM, and Android platforms. This allows future OS version updates to be managed in one location rather than updating multiple helix-queues-setup.yml templates throughout the codebase."

You'll need to manually update the PR description with this or a similar condensed version.

Pull Request Overview

This PR introduces centralized Helix platform alias definitions by adding two YAML configuration files that define stable variable aliases for latest and oldest supported OS versions across multiple platforms. This centralizes version-specific Helix queue names that were previously duplicated across multiple templates, enabling future OS version updates to be managed from a single location.

Creates comprehensive platform mappings for macOS, Linux, Windows, Browser/WASM, and Android
Separates latest and oldest supported versions into dedicated files for clear version management
Provides both public (.Open) and internal queue variants for each platform
