Feb 1, 2025February 2025 monthly summary for finnishtransportagency/harja. Focused on delivering secure, reliable authentication flows, improving API semantics, and stabilizing testing/observability while maintainingMigrations and data integrity. Key features delivered: - Public Key and JWT Handling Refactor and Wiring: consolidated public key retrieval, standardized header handling, wired IAM public-key URL into configuration, and unified fetch helper to reduce duplication. - GET Header Enhancement: added a reminder header to improve request semantics and client guidance. - Observability and Logging: enhanced logging, added async logging, and made public-key logging visible for traceability in production and tests. - UX/config improvements: authentication labeling rename to Authentikointi and related configuration refinements; groundwork for development-mode handling and key rotation tests. Major bugs fixed: - User Access and JWT Verification Bugs: fixed user permission removal failures; validated JWT signatures for user roles; ensured proper destruction of new material values to avoid leaks. - Token presence monitoring and alerts: enforced token existence with Slack alerts and associated tests. - Stability and robustness: prevented Harja crashes and resolved related cache/test flakiness. Overall impact and accomplishments: - Strengthened security posture (JWT validation, public-key handling) and reduced risk of leaks. - Improved API semantics and traceability, enabling easier integration and faster debugging. - Increased reliability of authentication flows and stability of the system, lowering mean time to restore. - Improved maintainability through focused refactors, test hygiene, migrations, and clearer configuration. Technologies/skills demonstrated: - JWT and public-key infrastructure, IAM integration, header management, and refactoring. - Observability: advanced logging (async), header/docs logging, and traceability. - Testing framework enablement, test data validation, and infrastructure stabilization. - Database migrations and schema maintenance activities to support ongoing changes.
