Worked on enhancing the runner lifecycle management in the actions/runner repository by developing a robust V2 runner deletion flow. This involved refactoring the existing logic to introduce the asynchronous DeleteRunnerAsync method in RunnerDotcomServer.cs, leveraging C# for backend development and system design. A configuration toggle, UseV2Flow, was implemented to allow selective activation of the new flow, ensuring backward compatibility while improving efficiency and maintainability. The approach focused on API integration and careful refactoring to support future scalability. The work delivered a more reliable and flexible runner deletion process, positioning the system for ongoing enhancements without disrupting existing functionality.
