open-telemetry/opentelemetry-java v1.65.0

Version 1.65.0

on GitHub

NOTE: The opentelemetry-exporter-zipkin artifact has stopped being published. It was deprecated in a prior release. Users should migrate to OTLP or use a Zipkin-compatible collector exporter.

API

• Ignore empty baggage keys in ImmutableBaggage.put (#8658)
• Use NumberFormatException in baggage decoder (#8593)
• Fix TraceStateBuilder.remove corrupting the builder when the same key is removed twice (#8613)

Incubating

• Add bound instrument APIs (BoundLongCounter, BoundDoubleCounter, BoundLongHistogram, BoundDoubleHistogram, BoundLongUpDownCounter, BoundDoubleUpDownCounter, BoundLongGauge, BoundDoubleGauge) to the incubator metrics API (#8527)

Extensions

• Trace propagators: Fix JaegerPropagator baggage header key case sensitivity (#8496)
• Trace propagators: Do not overwrite existing baggage with empty baggage in JaegerPropagator (#8632)
• Trace propagators: Skip empty baggage keys in OtTracePropagator extract (#8631)
• Trace propagators: Stop parsing a jaeger-baggage header after 64 tokens, including malformed tokens (#8702)

SDK

• Update SDK attributes implementation (AttributesMap) to enforce last-value-win semantics based on string value of AttributeKey.getKey() (#8548)

Traces

• Add Sampler shutdown lifecycle: Sampler now extends Closeable and exposes a default shutdown() invoked when the SdkTracerProvider is shut down; JaegerRemoteSampler implements it to stop its polling executor (#8574)

Metrics

• Gate PeriodicMetricReader self-observability metrics by internal telemetry version (#8597)
• Record error.type on failed collections in PeriodicMetricReader (#8650)
• Testing: Fix LongExemplarAssert.hasFilteredAttributesSatisfyingExactly to enforce exact attribute matching (#8518)

Logs

• Fix ReadWriteLogRecord default getObservedTimestampEpochNanos returning the record timestamp (#8504)

Profiles

• Fix profiles data model attribute count parameter name and timestamp doc unit (#8514)

Exporters

• WARNING Zipkin: Delete opentelemetry-exporter-zipkin; the artifact is no longer published (#8677)
• OTLP: Use HTTP error response bodies in HttpExporter warning logs (#8428)
• OTLP: Fix OkHttpHttpSender mTLS when using the platform default trust store (#8565)
• OTLP: Fix sign extension on LogRecord flags in the low-allocation log marshaler (#8493)
• OTLP: Standardize OkHttpHttpSender, JdkHttpSender, and UpstreamGrpcSender shutdown to await executor/channel termination (#8495, #8627, #8624)
• OTLP: Log the underlying except/ion when a gRPC response frame is invalid (#8626)
• OTLP: Avoid the unsafe string encoder on Android (#8637)
• Prometheus: Merge colliding Prometheus label values (#8364)
• Prometheus: Fix PrometheusHttpServer.toBuilder() dropping the configured default handler (#8619)
• Logging: Output event name in SystemOutLogRecordExporter (#8609)
• Logging: Include aggregation temporality in LoggingMetricExporter toString (#8623)

Extensions

• Autoconfigure: Avoid exposing configuration values in error messages (#8669)
• Declarative config: Fix Jaeger sampler polling interval configuration (#8668)
• Declarative config: Remove duplicate getStringList resolver in DeclarativeConfigPropertyUtil (#8572)
• Declarative config: Replace jsonschema2pojo with a hand-rolled POJO generator (#8600)
• Incubator: Restore compliance between composite samplers code and the spec (#8450)

Shims

• DEPRECATION Deprecate the OpenCensus shim public API (#8674)
• OpenCensus: Preserve OpenCensus status description when converting to OpenTelemetry (#8511)
• OpenCensus: Add links to the OpenTelemetry span instead of logging a warning and dropping them (#8635)
• OpenTracing: Return null from TracerShim extract when the carrier has no span context (#8505)
• OpenTracing: Return the extracted SpanContext when it is sampled but invalid (#8634)

Project tooling

• Pin japicmp baseline in version.gradle.kts (#8591)
• Update contributing guide in response to feedback (#8655)
