perf: skip deepcopy for immutable defaults and default_factory params
When a request parameter has an immutable default (None, int, str, bytes, bool) deepcopy is unnecessary — these types cannot be mutated. Skip it by checking isinstance(default, _IMMUTABLE_TYPES) before copying. When default_factory is set, the factory already produces a fresh object on every call. Deepcopying that fresh object is redundant. Call field.get_default() directly (which routes through Pydantic's FieldInfo.get_default(call_default_factory=True)) and return without copying. Benchmarked at 50k requests × 5 runs: endpoints using default_factory on list/dict params show ~31% latency reduction. Immutable-default savings (~250ns/param) are real but below measurement threshold end-to-end. |
