Dec 1, 2024December 2024 monthly summary for rossvideo/Catena focusing on security, build/test infrastructure, and documentation. Implemented scope-based authorization with an Authorizer, integrating with Device, IParam, and ParamDescriptor to enforce read/write permissions. Fixed inverted authorization check and removed an unnecessary Device::LockGuard to improve reliability of access control. Enhanced testing and build automation by adding a gRPC connection installer test and restructuring CMake/.gitignore for cleaner install paths and dependencies, plus a status update service example. Expanded installation testing documentation with build/test steps (CMake/Ninja) and Linux toolchain fixes to improve developer onboarding and CI reliability. Resolved node_modules installation handling by ensuring it installs as a directory to support codegen dependencies.

Nov 1, 2024Month 2024-11 highlights for rossvideo/Catena: Delivered key SDK advancements focused on variant data types, modular code generation, and command generation. Implemented Variant Types Support with nested variants and arrays, enhanced code generation and usage examples, and added constraints for robust modeling of device parameters. Introduced Modular Parameter Definitions Import and a DeviceModel class to centralize device descriptors, simplifying codegen and parameter imports. Added Code Generation for Commands in the C++ SDK to generate command initialization and descriptions in artifacts. Improved build reliability with path/root discovery fixes, performed extensive codebase cleanup, tests for menu constraints, and documentation enhancements. Refined schema organization by splitting device and parameter schemas for better validation and maintenance. These changes drive faster device onboarding, reduce maintenance effort, and improve overall system reliability.
