- script/build_helpers.py: when injecting a non-MULTI_CONF component
into the post-validation config, run its CONFIG_SCHEMA with {} so
defaults are populated. Without this, socket got config = {} and
socket.FILTER_SOURCE_FILES crashed with KeyError on
'implementation' (the schema's defaulted key was never filled in).
Falls back to {} if the schema can't validate empty input.
- tests/components/json/__init__.py: enable codegen for json so its
to_code runs during cpp unit test builds, registering the
ArduinoJson library. Required for any api dep test, since
json_util.cpp #includes <ArduinoJson.h>.
Locally verified 'script/cpp_unit_test.py api' now compiles and runs;
ProtoMacVarint test suite (9 cases) passes.
Three fixes so 'script/cpp_unit_test.py api' actually compiles instead
of crashing in build setup:
1. script/build_helpers.py: when adding transitive component
dependencies to the post-validation config, use {} (dict) instead
of [] (list) for non-MULTI_CONF components. socket's
FILTER_SOURCE_FILES (and any other code that subscripts
CORE.config[component] with a string key) was crashing because
socket got config = [] from setdefault.
2. esphome/components/api/api_pb2_service.cpp + the codegen in
script/api_protobuf/api_protobuf.py: wrap the generated
APIConnection::read_message_ definition in #ifdef USE_API. The
class itself is only declared inside #ifdef USE_API in
api_connection.h, so without the guard the .cpp fails to compile
in any build that pulls in the api source files without setting
USE_API (e.g. cpp unit tests of api dependencies).
Adds a (mac_address) field option that switches uint64 fields holding
48-bit MAC addresses to a specialized varint encoder. The fast path
emits exactly 7 bytes when bits [42..47] are non-zero (the common case
for real MACs, since OUIs occupy the top 24 bits) -- one bounds check
and 7 independent stores instead of the 7-iteration shift+branch loop.
calc_uint64_48bit_force mirrors the same fast path in size calculation.
Applied to BluetoothLERawAdvertisement.address, the per-advertisement
address encode in BluetoothLERawAdvertisementsResponse drops from a
serialized per-byte loop to straight-line code.
CI measured 90.6ms after the lazy-import refactor lands. Set baseline to
91ms with 15% margin (ceiling 104.65ms, ~14ms headroom for GHA variance
over the observed measurement).
CI now measures 81.2ms after the zeroconf/writer/yaml_util lazy loads.
Reset baseline to 82ms with the 15% margin (ceiling 94.3ms, ~13ms
headroom for GHA variance).
