- Move BASE_CODEGEN_COMPONENTS and USE_TIME_TIMEZONE_FLAG to test_helpers.py
- Use shared constants in both cpp_unit_test.py and cpp_benchmark.py
- Move json import to top level in cpp_benchmark.py
- Refactor setup_codspeed_lib.py into focused helper functions
- Combine clone + submodule init, use --shallow-submodules
Add automated benchmarks using Google Benchmark to prevent performance
regressions in the API protobuf encoding/decoding and core loop paths.
Benchmarks cover:
- Protobuf encode: SensorState, BinarySensorState, HelloResponse,
LightState, DeviceInfoResponse (20 nested devices + 20 areas)
- Protobuf decode: HelloRequest, SwitchCommand, LightCommand
- Protobuf calculate_size and full calc+encode send path
- Varint parse/encode/size for various value ranges
- Scheduler call/next_schedule_in with idle and active timers
- Application loop component dispatch and blocking guard overhead
Infrastructure:
- Extract shared build logic from cpp_unit_test.py into test_helpers.py
- Add cpp_benchmark.py mirroring the unit test build pattern
- Support benchmark.yaml per component dir for declaring dependencies
- Add CodSpeed CI workflow triggered on api/core changes
- Fix ProtoMessage protected destructor on host platform
