open-telemetry/opentelemetry-go v0.11.0

Release v0.11.0

on GitHub

Added

• Noop and InMemory SpanBatcher implementations to help with testing integrations. (#994)
• Integration tests for more OTel Collector Attribute types. (#1062)
• A dimensionality-reducing metric Processor. (#1057)
• Support for filtering metric label sets. (#1047)
• Support for exporting array-valued attributes via OTLP. (#992)

Changed

• Rename sdk/metric/processor/test to sdk/metric/processor/processortest. (#1049)
• Rename sdk/metric/controller/test to sdk/metric/controller/controllertest. (#1049)
• Rename api/testharness to api/apitest. (#1049)
• Rename api/trace/testtrace to api/trace/tracetest. (#1049)
• Change Metric Processor to merge multiple observations. (#1024)
• The go.opentelemetry.io/otel/bridge/opentracing bridge package has been made into its own module.
  This removes the package dependencies of this bridge from the rest of the OpenTelemetry based project. (#1038)
• Renamed go.opentelemetry.io/otel/api/standard package to go.opentelemetry.io/otel/semconv to avoid the ambiguous and generic name standard and better describe the package as containing OpenTelemetry semantic conventions. (#1016)
• The environment variable used for resource detection has been changed from OTEL_RESOURCE_LABELS to OTEL_RESOURCE_ATTRIBUTES (#1042)
• Replace WithSyncer with WithBatcher in examples. (#1044)
• Replace the google.golang.org/grpc/codes dependency in the API with an equivalent go.opentelemetry.io/otel/codes package. (#1046)
• Merge the go.opentelemetry.io/otel/api/label and go.opentelemetry.io/otel/api/kv into the new go.opentelemetry.io/otel/label package. (#1060)
• Unify Callback Function Naming.
  Rename *Callback with *Func. (#1061)
• CI builds validate against last two versions of Go, dropping 1.13 and adding 1.15. (#1064)

Removed

• Duplicate, unused API sampler interface. (#999)
  Use the Sampler interface provided by the SDK instead.
• The grpctrace instrumentation was moved to the go.opentelemetry.io/contrib repository and out of this repository.
  This move includes moving the grpc example to the go.opentelemetry.io/contrib as well. (#1027)
• The WithSpan method of the Tracer interface.
  The functionality this method provided was limited compared to what a user can provide themselves.
  It was removed with the understanding that if there is sufficient user need it can be added back based on actual user usage. (#1043)
• The RegisterSpanProcessor and UnregisterSpanProcessor functions.
  These were holdovers from an approach prior to the TracerProvider design. They were not used anymore. (#1077)
• The oterror package. (#1026)
• The othttp and httptrace instrumentations were moved to go.opentelemetry.io/contrib. (#1032)

Fixed

• The semconv.HTTPServerMetricAttributesFromHTTPRequest() function no longer generates the high-cardinality http.request.content.length label. (#1031)
• Correct instrumentation version tag in Jaeger exporter. (#1037)
• The SDK span will now set an error event if the End method is called during a panic (i.e. it was deferred). (#1043)
• Move internally generated protobuf code from the go.opentelemetry.io/otel to the OTLP exporter to reduce dependency overhead. (#1050)
• The otel-collector example referenced outdated collector processors. (#1006)
