otel_chopper 0.2.0

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

Changelog

0.2.0 - 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.
