otel_chopper 0.3.0

OpenTelemetry instrumentation for `package:chopper`. A Chopper Interceptor that emits HTTP CLIENT spans with `http.*` semconv attributes and injects W3C trace context headers.

Changelog

0.3.0 - 2026-10-11

Changed

• Requires dartastic_opentelemetry_api >=1.0.0-rc.4 <1.0.0-rc.5.
• Context is propagated with the app's configured propagators (OTelAPI.textMapPropagator: W3C trace context and baggage by default, OTEL_PROPAGATORS to change them) instead of a fixed W3C propagator.
• Breaking: depends on dartastic_opentelemetry_api only, no longer on the SDK. The application chooses and initializes the OpenTelemetry SDK. Parameters and fields typed with SDK classes now use the API types (APITracer, APISpan, APILogger, ...); SDK instances are still accepted wherever an API type is expected.

0.2.0 - 2026-08-08

Changed

• Semantic conventions updated to the current OTel registry: deprecated attribute keys are no longer emitted (db.system -> db.system.name, db.operation -> db.operation.name, rpc.system -> rpc.system.name, with rpc.service folded into a fully-qualified rpc.method).
• Dependency floors raised to dartastic_opentelemetry ^1.1.0-beta.12 and dartastic_opentelemetry_api ^1.0.0-rc.1. The previous floors declared compatibility with API versions that predate the semconv enums this package uses and could not actually resolve-and-compile.
• repository URL corrected to the canonical Dartastic org casing so pub.dev repository verification succeeds.

Added

• OTelChopperInterceptor — a Chopper Interceptor that opens an HTTP CLIENT span around each outbound request and injects the W3C traceparent header.
• Span attributes: http.request.method, url.full, server.address, server.port, http.response.status_code. 4xx/5xx responses flip span status to Error. The deprecated http.method legacy key is not emitted.
• Zone-scoped suppression (runWithoutChopperInstrumentation / async variant).
• 4 tests using http.testing.MockClient (no network needed): span shape on success, error status flip, traceparent header injection, suppression scope.
