Jul 1, 2026July 2026 monthly summary for mozilla/treeherder. Focused on stabilizing CI tests and enhancing observability to accelerate debugging and business value realization. Key features and fixes include per-worker Redis-based cache isolation for pytest-xdist to prevent cross-worker cache flushing and flaky authentication tests, corrections to test imports (notably pushesStore) to eliminate module-not-found errors, and a utility plus config to dynamically update per-worker cache settings. Also introduced Google Cloud Platform structured logging to backend logs by attaching task_id, run_id, job_id, and component labels via contextvars, enabling queryable CI failure analysis. All work was designed to improve CI reliability, reduce debugging time, and provide richer operational signals.
