additions (3)

  • - cmd/mdatagen: Add support for supported_platforms in component metadata, allowing generated component tests to target explicitly supported platforms (#13319)
  • - pkg/xpdata: Add xhash.WithUint64 to hash a uint64 value without converting it to int64. (#16176) It produces the same hash as xhash.WithValue(pcommon.NewValueInt(int64(v))).
  • - pkg/exporterhelper: Expose PartitionConfig and NewDefaultPartitionConfig so that users can modify it. (#16197)

fixes (3)

  • - cmd/mdatagen: Fix the generated dataPointKey function triggering gosec G115 (uint64 to int64 conversion) in components that use mdatagen. (#16176) The generated hash values are unchanged.
  • - exporter/otlp_http: Report the URL the request was actually sent to in HTTP status error messages when a middleware rewrites the request URL. (#14673) Middleware RoundTrippers that clone the request before rewriting its URL left the configured placeholder URL in 4xx/5xx error messages. The exporter now reads the destination from the response instead.
  • - pkg/otelcol: Redact non-empty literal defaults in unexpanded env provider references such as ${env:NAME:-literal} in the raw config reported by the OpAMP extension when reports_raw_config is enabled (#16141) Empty defaults such as ${env:NAME:-} stay visible. Other provider schemes are unchanged.
