May 1, 2025May 2025 monthly summary for DataDog/dd-trace-rb focusing on business value and technical excellence. Key features delivered: - AppSec Security Engine Modernization: Introduced AppSec::SecurityEngine::Engine to manage WAF builder/config, load defaults, handle initialization errors, and rebuild the WAF handle when configurations change. Refactored Runner to work with WAF::Context, added a helper to create runners with a built context, migrated to a unified Engine, added type signatures, and switched AppSec to the Engine from the deprecated Processor. Enabled remote configuration handling and improved error handling. Major bugs fixed: - Fixed appsec security engine related specs to align with the new Engine-based architecture and ensure stability with the Engine transition. Documentation and dependencies: - Documentation and Dependency Maintenance: Updated automated PR template with conflict-resolution guidance to improve PR hygiene. Upgraded libddwaf dependency to 1.24.1 and adjusted related error handling for compatibility with the new library. Overall impact and accomplishments: - Delivered a unified, engine-based AppSec for WAF management, reducing configuration errors, enabling remote adjustments, and improving maintainability. The changes reduce deployment risk and enable faster iteration on security policies. - Achieved stronger type safety and clearer ownership with the Engine, simplifying onboarding and future enhancements. Technologies/skills demonstrated: - Ruby Engine architecture, WAF integration, and context-driven design (WAF::Context) - Type signatures and API stabilization - Remote configuration handling and robust error management - Dependency management and test maintenance
