Compare Source

Added

  • Add IsRandom and WithRandom on TraceFlags, and IsRandom on SpanContext in go.opentelemetry.io/otel/trace
    for W3C Trace Context Level 2 Random Trace ID Flag support. (#​8012)
  • Add service detection with WithService in go.opentelemetry.io/otel/sdk/resource. (#​7642)
  • Add DefaultWithContext and EnvironmentWithContext in go.opentelemetry.io/otel/sdk/resource to support plumbing context.Context through default and environment detectors. (#​8051)
  • Support attributes with empty value (attribute.EMPTY) in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc. (#​8038)
  • Support attributes with empty value (attribute.EMPTY) in go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc. (#​8038)
  • Support attributes with empty value (attribute.EMPTY) in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc. (#​8038)
  • Support attributes with empty value (attribute.EMPTY) in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp. (#​8038)
  • Support attributes with empty value (attribute.EMPTY) in go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp. (#​8038)
  • Support attributes with empty value (attribute.EMPTY) in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp. (#​8038)
  • Support attributes with empty value (attribute.EMPTY) in go.opentelemetry.io/otel/sdk/metric/metricdata/metricdatatest. (#​8038)
  • Add support for per-series start time tracking for cumulative metrics in go.opentelemetry.io/otel/sdk/metric.
    Set OTEL_GO_X_PER_SERIES_START_TIMESTAMPS=true to enable. (#​8060)
  • Add WithCardinalityLimitSelector for metric reader for configuring cardinality limits specific to the instrument kind. (#​7855)

Changed

  • Introduce the EMPTY Type in go.opentelemetry.io/otel/attribute to reflect that an empty value is now a valid value, with INVALID remaining as a deprecated alias of EMPTY. (#​8038)
  • Refactor slice handling in go.opentelemetry.io/otel/attribute to optimize short slice values with fixed-size fast paths. (#​8039)
  • Improve performance of span metric recording in go.opentelemetry.io/otel/sdk/trace by returning early if self-observability is not enabled. (#​8067)
  • Improve formatting of metric data diffs in go.opentelemetry.io/otel/sdk/metric/metricdata/metricdatatest. (#​8073)

Deprecated

  • Deprecate INVALID in go.opentelemetry.io/otel/attribute. Use EMPTY instead. (#​8038)

Fixed

  • Return spec-compliant TraceIdRatioBased description. This is a breaking behavioral change, but it is necessary to
    make the implementation spec-compliant. (#​8027)
  • Fix a race condition in go.opentelemetry.io/otel/sdk/metric where the lastvalue aggregation could collect the value 0 even when no zero-value measurements were recorded. (#​8056)
  • Limit HTTP response body to 4 MiB in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp to mitigate excessive memory usage caused by a misconfigured or malicious server.
    Responses exceeding the limit are treated as non-retryable errors. (#​8108)
  • Limit HTTP response body to 4 MiB in go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp to mitigate excessive memory usage caused by a misconfigured or malicious server.
    Responses exceeding the limit are treated as non-retryable errors. (#​8108)
  • Limit HTTP response body to 4 MiB in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp to mitigate excessive memory usage caused by a misconfigured or malicious server.
    Responses exceeding the limit are treated as non-retryable errors. (#​8108)
  • WithHostID detector in go.opentelemetry.io/otel/sdk/resource to use full path for kenv command on BSD. (#​8113)
  • Fix missing request.GetBody in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp to correctly handle HTTP2 GOAWAY frame. (#​8096)
