Summary of Changes

Hello, 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 introduces logic to allow multiple builds to run in parallel by enhancing the build check mechanism. By incorporating a test prefix and an on-spot status flag, the system can now differentiate between concurrent build instances, enabling both PR-based and daily scheduled runs to execute simultaneously without conflict.

Highlights

• Parallel Execution Logic: Updated the build check script to support parallel execution by filtering builds based on a test prefix and an optional 'on-spot' flag.
• Configuration Updates: Modified numerous daily test YAML configurations to pass the new test prefix and on-spot parameters to the build check script.

Code Review

This pull request updates the check_running_build.sh script and its usage in various YAML build files to support prefix-based filtering for parallel builds. My review identified several critical issues: the validation script tools/cloud-build/daily-tests/validate_daily_test_builds.py must be updated to accommodate the new script arguments, and the ${_TEST_PREFIX} variable in all modified YAML files must be quoted to prevent shell argument shifting when the prefix is empty. Additionally, I have suggested a logic improvement to ensure prefix-based filtering is applied more consistently, rather than being restricted only to on-spot builds.
