Jun 1, 2025June 2025: Delivered reliability and quality improvements for OpenRailAssociation/osrd. Implemented timezone-aware UTC datetimes across editoast and centralized ROOT_URL configuration via Clap, eliminating manual env parsing and reducing misconfigurations. Fixed a typo in an error message and corrected a timetable view variable name to resolve UI/runtime inconsistency. Performed a formatting cleanup with cargo fmt to standardize use statements across editoast. These changes improve deployment predictability, runtime correctness, and code maintainability, supporting faster iterations and scale.

Apr 1, 2025April 2025 (OpenRailAssociation/osrd) focused on strengthening error handling and reliability in data retrieval and related modules. Delivered enhanced data retrieval error propagation and model-specific error handling, with a clean migration path away from generic InternalError to precise model-defined errors. This work improves observability, reduces debugging time, and increases safety for production deployments across retrieval, batch operations, existence checks, and timetable features. The changes position the codebase for easier maintenance and future enhancements, with backward-compatible deprecation of Retrieve::retrieve in favor of Retrieve::retrieve_real.

Nov 1, 2024November 2024: OpenRailAssociation/osrd delivered a suite of modularization and data-layer improvements that streamline architecture, improve reliability, and accelerate feature delivery. Key outcomes include centralizing OpenAPI generation in the client module (OpenApiRoot.build_openapi used directly in print_openapi); modularizing the healthcheck CLI into the client; refactoring EdItoast server startup/config using a ServerConfig in the views module; upgrading MQ client URI handling to a strong Url type; and a comprehensive EdItoast data layer/ORM refactor (Diesel DSL, field handling improvements, and typo/lifetime cleanups). These changes simplify onboarding, reduce runtime/configuration errors, and establish a robust foundation for rapid, safe evolution of the product.
