Worked on the envoyproxy/gateway repository to address nondeterministic routing behavior by implementing deterministic sorting for HTTPRoutes. The solution involved ordering routes first by creation timestamp, then by namespace, and finally by name, ensuring stable and predictable routing outcomes. Updated the associated tests to reflect this new sorting logic, which reduced test flakiness and improved the reliability of the routing layer. Utilized Go and YAML to modify both the core routing logic and the test suite, applying knowledge of the Gateway API and Kubernetes environments. This work contributed to the project’s release readiness by enhancing routing consistency and test stability.
