Updates go.opentelemetry.io/otel from 1.46.0 to 1.47.0

Release notes

Sourced from go.opentelemetry.io/otel's releases.

v1.47.0/v0.69.0/v0.23.0/v0.1.0

This release contains the first stable release of the OpenTelemetry Go Logs API and SDK. Our project stability guarantees now apply to the following modules:

• go.opentelemetry.io/otel/log
• go.opentelemetry.io/otel/sdk/log

See our versioning policy for more information about these stability guarantees.

Added

• Add String method for KeyValue type in go.opentelemetry.io/otel/attribute. (#8205)
• Add String method for Set type in go.opentelemetry.io/otel/attribute. (#8347)
• Add WithMaxExportBatchSize to go.opentelemetry.io/otel/sdk/metric to configure the maximum export batch size for PeriodicReader. (#8960)
• Add WithAttributeValueDepthLimit, DefaultAttributeValueDepthLimit, and SpanLimits.AttributeValueDepthLimit in go.opentelemetry.io/otel/sdk/trace to configure the maximum depth of span, event, link, and instrumentation scope attribute values. (#8938)
• Add WithAttributeValueDepthLimit in go.opentelemetry.io/otel/sdk/log to configure the maximum depth of log record and instrumentation scope attribute values. (#8938)
• Add WithMaxResponseSize to go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp, go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp, and go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp. (#8941)
• Add experimental ProbabilitySampler in go.opentelemetry.io/otel/sdk/trace/x that conforms to the OpenTelemetry specification's threshold-based sampling algorithm. (#8123)
• Add experimental *Binder extension interfaces in go.opentelemetry.io/otel/metric/x for instruments that support binding attributes ahead of time. (#8760)
• Add the experimental Finisher synchronous metric instrument extension interface to go.opentelemetry.io/otel/metric/x. (#8906)

Changed

• Use the OpenTelemetry Attribute Collection representation for non-OTLP protocols for metric data diffs in go.opentelemetry.io/otel/sdk/metric/metricdata/metricdatatest. (#8993)
• Apply a maximum depth of 64 by default to span, event, link, log record, and instrumentation scope attribute values in go.opentelemetry.io/otel/sdk/trace and go.opentelemetry.io/otel/sdk/log. (#8938)
• Reduce allocations when applying attribute value length limits in go.opentelemetry.io/otel/sdk/trace and go.opentelemetry.io/otel/sdk/log by rebuilding composite values only when truncation is needed. (#8912)
• Decode traceparent using a hex lookup table in go.opentelemetry.io/otel/propagation, which rejects the specification-disallowed upper-case characters without a separate scan of the header. (#8739)
• Decode all characters at constant indices in TraceIDFromHex and SpanIDFromHex in go.opentelemetry.io/otel/trace to eliminate bounds checks. (#8740)

Fixed

• Count valid U+FFFD replacement characters toward attribute value length limits in go.opentelemetry.io/otel/trace, go.opentelemetry.io/otel/sdk/trace, and go.opentelemetry.io/otel/sdk/log.
• Truncate string attribute values to empty strings when the configured length limit is zero, including malformed UTF-8, in go.opentelemetry.io/otel/trace, go.opentelemetry.io/otel/sdk/trace, and go.opentelemetry.io/otel/sdk/log. (#9054)
• Fix a data race in NewPeriodicReader where r.inst was assigned after the background goroutine was launched in go.opentelemetry.io/otel/sdk/metric. (#9028)
• Prevent precision loss for large int64 values in Sum, Histogram, and ExponentialHistogram aggregations in go.opentelemetry.io/otel/sdk/metric. (#8981)
• Ensure grpc.DialOption values passed via WithDialOption take precedence over conflicting internally-computed defaults in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc, go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc, and go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc. (#8805, #8834, #8836)
• Treat overflowing OTEL_METRIC_EXPORT_INTERVAL and OTEL_METRIC_EXPORT_TIMEOUT values as invalid in go.opentelemetry.io/otel/sdk/metric. (#8800)
• Prevent a panic in NewFixedSizeReservoir and FixedSizeReservoirProvider when given a negative size in go.opentelemetry.io/otel/sdk/metric/exemplar; negative sizes are now clamped to zero, consistent with a size of zero. (#8832)
• Preserve exponential histogram ZeroThreshold during OTLP metric export in go.opentelemetry.io/otel/exporters/otlp/otlpmetric. (#8801)
• Ensure metric helpers in go.opentelemetry.io/otel/semconv/v1.32.0, go.opentelemetry.io/otel/semconv/v1.33.0, and go.opentelemetry.io/otel/semconv/v1.34.0 record measurements only once when no attributes are provided. (#8849)
• Treat empty OTEL_TRACES_SAMPLER and OTEL_TRACES_SAMPLER_ARG values as unset in go.opentelemetry.io/otel/sdk/trace. (#8873)
• Normalize global OTEL_EXPORTER_OTLP_ENDPOINT path joining in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp so trailing-slash base URLs do not produce double-slash log export paths. (#8864)
• Prevent a deadlock when formatting an error passed to RecordError calls back into the span in go.opentelemetry.io/otel/sdk/trace. (#8815)
• Prevent SimpleSpanProcessor.Shutdown from panicking when constructed with a nil exporter in go.opentelemetry.io/otel/sdk/trace. (#8844)
• Propagate invalid exponential histogram scale errors to Prometheus exporter self-observability metrics in go.opentelemetry.io/otel/exporters/prometheus. (#8839)

• Decode traceparent using a hex lookup table in go.opentelemetry.io/otel/propagation, which rejects the specification-disallowed upper-case characters without a separate scan of the header. (#8739)
• Decode all characters at constant indices in TraceIDFromHex and SpanIDFromHex in go.opentelemetry.io/otel/trace to eliminate bounds checks. (#8740)

Fixed

• Count valid U+FFFD replacement characters toward attribute value length limits in go.opentelemetry.io/otel/trace, go.opentelemetry.io/otel/sdk/trace, and go.opentelemetry.io/otel/sdk/log.
• Truncate string attribute values to empty strings when the configured length limit is zero, including malformed UTF-8, in go.opentelemetry.io/otel/trace, go.opentelemetry.io/otel/sdk/trace, and go.opentelemetry.io/otel/sdk/log. (#9054)
• Fix a data race in NewPeriodicReader where r.inst was assigned after the background goroutine was launched in go.opentelemetry.io/otel/sdk/metric. (#9028)
• Prevent precision loss for large int64 values in Sum, Histogram, and ExponentialHistogram aggregations in go.opentelemetry.io/otel/sdk/metric. (#8981)
• Ensure grpc.DialOption values passed via WithDialOption take precedence over conflicting internally-computed defaults in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc, go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc, and go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc. (#8805, #8834, #8836)
• Treat overflowing OTEL_METRIC_EXPORT_INTERVAL and OTEL_METRIC_EXPORT_TIMEOUT values as invalid in go.opentelemetry.io/otel/sdk/metric. (#8800)
• Prevent a panic in NewFixedSizeReservoir and FixedSizeReservoirProvider when given a negative size in go.opentelemetry.io/otel/sdk/metric/exemplar; negative sizes are now clamped to zero, consistent with a size of zero. (#8832)
• Preserve exponential histogram ZeroThreshold during OTLP metric export in go.opentelemetry.io/otel/exporters/otlp/otlpmetric. (#8801)
• Ensure metric helpers in go.opentelemetry.io/otel/semconv/v1.32.0, go.opentelemetry.io/otel/semconv/v1.33.0, and go.opentelemetry.io/otel/semconv/v1.34.0 record measurements only once when no attributes are provided. (#8849)
• Treat empty OTEL_TRACES_SAMPLER and OTEL_TRACES_SAMPLER_ARG values as unset in go.opentelemetry.io/otel/sdk/trace. (#8873)
• Normalize global OTEL_EXPORTER_OTLP_ENDPOINT path joining in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp so trailing-slash base URLs do not produce double-slash log export paths. (#8864)
• Prevent a deadlock when formatting an error passed to RecordError calls back into the span in go.opentelemetry.io/otel/sdk/trace. (#8815)
• Prevent SimpleSpanProcessor.Shutdown from panicking when constructed with a nil exporter in go.opentelemetry.io/otel/sdk/trace. (#8844)
• Propagate invalid exponential histogram scale errors to Prometheus exporter self-observability metrics in go.opentelemetry.io/otel/exporters/prometheus. (#8839)
