Jun 1, 20252025-06 monthly summary – hove-io/navitia Key outcomes: - Realtime schedule direction handling improvements delivered: added support for multiple terminus URIs for direction validation, aligned direction notes with the determined direction, and implemented a fallback when terminus URIs are empty. This enhances validation accuracy and resilience in live routing scenarios. - SSL verification security fix for ForsetiMultiStop: restored SSL certificate verification for HTTP requests after a prior insecure change, ensuring secure communications and reducing risk of man-in-the-middle attacks. - CI/CD stability upgrade: upgraded MIMIR version in the pipeline from v3.5.6 to v3.5.7, improving build stability and compatibility with the rest of the stack. - Tech debt and compatibility improvements: improved Python 2/3 compatibility and binary IO handling by switching to binary writes where appropriate, ensuring Python 3 support and aligning dependencies and build steps for Debian11 environments. Major bugs fixed: - Restored SSL verification in ForsetiMultiStop to re-enable secure HTTP communications. - Cross-version compatibility fixes for Python 2/3 and binary IO adjustments to prevent runtime and deployment issues. Overall impact and accomplishments: - Improved reliability, security, and maintainability of the navitia repository. - Enhanced live-routing validation accuracy, leading to more trustworthy route guidance. - More stable builds and deployments through CI/CD upgrades and modernization of IO/data handling. Technologies/skills demonstrated: - Python 2/3 interoperability, binary IO handling, and cross-version compatibility. - Secure HTTP practices (SSL/TLS verification). - CI/CD pipeline maintenance and dependency management. - Code quality through cleanup and refactoring activities when applicable.
