[dependabot]

Bumps go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc from 0.19.0 to 0.21.0.

Release notes

Sourced from go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc's releases.

Release v0.20.0

Added

• The OTLP exporter now has two new convenience functions, NewExportPipeline and InstallNewPipeline, setup and install the exporter in tracing and metrics pipelines. (#1373)
• Adds semantic conventions for exceptions. (#1492)
• Added Jaeger Environment variables: OTEL_EXPORTER_JAEGER_AGENT_HOST, OTEL_EXPORTER_JAEGER_AGENT_PORT These environment variables can be used to override Jaeger agent hostname and port (#1752)
• Option ExportTimeout was added to batch span processor. (#1755)
• trace.TraceFlags is now a defined type over byte and WithSampled(bool) TraceFlags and IsSampled() bool methods have been added to it. (#1770)
• The Event and Link struct types from the go.opentelemetry.io/otel package now include a DroppedAttributeCount field to record the number of attributes that were not recorded due to configured limits being reached. (#1771)
• The Jaeger exporter now reports dropped attributes for a Span event in the exported log. (#1771)
• Adds test to check BatchSpanProcessor ignores OnEnd and ForceFlush post Shutdown. (#1772)
• Extract resource attributes from the OTEL_RESOURCE_ATTRIBUTES environment variable and merge them with the resource.Default resource as well as resources provided to the TracerProvider and metric Controller. (#1785)
• Added WithOSType resource configuration option to set OS (Operating System) type resource attribute (os.type). (#1788)
• Added WithProcess* resource configuration options to set Process resource attributes. (#1788)
  • process.pid
  • process.executable.name
  • process.executable.path
  • process.command_args
  • process.owner
  • process.runtime.name
  • process.runtime.version
  • process.runtime.description
• Adds k8s.node.name and k8s.node.uid attribute keys to the semconv package. (#1789)
• Added support for configuring OTLP/HTTP and OTLP/gRPC Endpoints, TLS Certificates, Headers, Compression and Timeout via Environment Variables. (#1758, #1769 and #1811)
  • OTEL_EXPORTER_OTLP_ENDPOINT
  • OTEL_EXPORTER_OTLP_TRACES_ENDPOINT
  • OTEL_EXPORTER_OTLP_METRICS_ENDPOINT
  • OTEL_EXPORTER_OTLP_HEADERS
  • OTEL_EXPORTER_OTLP_TRACES_HEADERS
  • OTEL_EXPORTER_OTLP_METRICS_HEADERS
  • OTEL_EXPORTER_OTLP_COMPRESSION
  • OTEL_EXPORTER_OTLP_TRACES_COMPRESSION
  • OTEL_EXPORTER_OTLP_METRICS_COMPRESSION

  • OTEL_EXPORTER_OTLP_CERTIFICATE
  • OTEL_EXPORTER_OTLP_TRACES_CERTIFICATE
  • OTEL_EXPORTER_OTLP_METRICS_CERTIFICATE
• Adds otlpgrpc.WithTimeout option for configuring timeout to the otlp/gRPC exporter. (#1821)

Fixed

• The Span.IsRecording implementation from go.opentelemetry.io/otel/sdk/trace always returns false when not being sampled. (#1750)
• The Jaeger exporter now correctly sets tags for the Span status code and message. This means it uses the correct tag keys ("otel.status_code", "otel.status_description") and does not set the status message as a tag unless it is set on the span. (#1761)
• The Jaeger exporter now correctly records Span event's names using the "event" key for a tag. Additionally, this tag is overridden, as specified in the OTel specification, if the event contains an attribute with that key. (#1768)
• Zipkin Exporter: Ensure mapping between OTel and Zipkin span data complies with the specification. (#1688)

Changed

• HistogramReservoir in go.opentelemetry.io/otel/sdk/metric/exemplar now uses a time-unbiased sampling algorithm for exemplars. (#8306)
• ⚠️ Breaking Change: Use go.opentelemetry.io/otel/attribute.Value and go.opentelemetry.io/otel/attribute.KeyValue for log bodies and attributes in go.opentelemetry.io/otel/log, go.opentelemetry.io/otel/log/logtest, go.opentelemetry.io/otel/sdk/log, and go.opentelemetry.io/otel/sdk/log/logtest. (#8490)
• Encode log bodies and attributes as go.opentelemetry.io/otel/attribute.Value JSON in go.opentelemetry.io/otel/exporters/stdout/stdoutlog. (#8490)
• Improve the performance of hashing BOOLSLICE, INT64SLICE, FLOAT64SLICE, and STRINGSLICE attribute values by avoiding reflection for short slices in go.opentelemetry.io/otel/attribute. (#8511)
• ⚠️ Breaking Change: WithEndpointURL in go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp no longer appends the default signal path when an endpoint URL has no path, making the behavior consistent with go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp and with setting the endpoint through OTEL_EXPORTER_OTLP_METRICS_ENDPOINT. If the URL has no path component, the root path (/) is used. Use WithEndpointURL(url.JoinPath(endpoint, "/v1/metrics")) to preserve the previous behavior. (#8538)
• ⚠️ Breaking Change: WithEndpointURL in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp no longer appends the default signal path when an endpoint URL has no path, making the behavior consistent with go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp and with setting the endpoint through OTEL_EXPORTER_OTLP_TRACES_ENDPOINT. If the URL has no path component, the root path (/) is used. Use WithEndpointURL(url.JoinPath(endpoint, "/v1/traces")) to preserve the previous behavior. (#8538)

Deprecated

• Deprecate WithExportBufferSize in go.opentelemetry.io/otel/sdk/log. The option remains available for source compatibility but no longer affects behavior; BatchProcessor no longer maintains a separate export-request buffer. (#8620)

Removed

• ⚠️ Breaking Change: Remove Kind, Value, KeyValue, their constructors, and attribute conversion helpers from go.opentelemetry.io/otel/log. (#8490)
• ⚠️ Breaking Change: Remove the AttributeValueLengthLimit and AttributeCountLimit fields from RecordFactory in go.opentelemetry.io/otel/sdk/log/logtest; records produced by the factory now keep attribute limits disabled so test code can append exact attributes. (#8556)

Fixed

• Apply TLS certificates configured through environment variables to gRPC connections in go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc.
• Prevent panics in go.opentelemetry.io/otel/bridge/opentracing when OpenTracing baggage is propagated concurrently with Span.SetBaggageItem.
• Fix an off-by-one error in FixedSizeReservoir in go.opentelemetry.io/otel/sdk/metric/exemplar that prevented the first exemplar from being sampled after the reservoir was filled. (#8309)
• Interpret HTTP Retry-After header values as seconds instead of nanoseconds when retrying OTLP HTTP exports in 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. (#8383)
• Fix a memory leak in the Reservoir implementation in go.opentelemetry.io/otel/sdk/metric/exemplar, where storing the full context.Context pinned large objects such as gRPC transport buffers. (#8389)

Failed CI Steps

• Check integrations otlp_input_otel

History

[github-actions]

TL;DR

The otlp_input_otel CI failure is a dependency/API compatibility break introduced by the Dependabot bump: otlploggrpc and otel/log were upgraded, but otlploghttp remained at v0.19.0, which no longer compiles against the newer log API.

Remediation

• Align OTLP log exporter versions in packages/otlp_input_otel/_dev/deploy/docker/generator/go.mod by upgrading go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp from v0.19.0 to v0.21.0 (to match otlploggrpc v0.21.0).
• Update the log body assignment in packages/otlp_input_otel/_dev/deploy/docker/generator/main.go to the current API (attribute.StringValue(...) instead of otellog.StringValue(...)).
• Re-run .buildkite/scripts/test_one_package.sh packages/otlp_input_otel ... (or at minimum go test ./... in packages/otlp_input_otel/_dev/deploy/docker/generator) to validate.

Investigation details

Root Cause

This is a dependency issue caused by a partial OpenTelemetry log stack upgrade in the generator module.

• In packages/otlp_input_otel/_dev/deploy/docker/generator/go.mod, line 7 upgrades otlploggrpc to v0.21.0 and line 13 upgrades otel/log to v0.21.0, but line 8 leaves otlploghttp at v0.19.0.
• packages/otlp_input_otel/_dev/deploy/docker/generator/main.go imports both log exporters (lines 17-18), so the stale otlploghttp dependency is compiled and fails against the newer log API.

Evidence

• Build: https://buildkite.com/elastic/integrations/builds/50016
• Job/step: Check integrations otlp_input_otel
• Key log excerpt (reproduced from PR head dependencies):

# go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp/internal/transform
.../otlploghttp@v0.19.0/internal/transform/log.go:102:36: undefined: api.KeyValue
.../otlploghttp@v0.19.0/internal/transform/log.go:283:31: undefined: api.Value
...
FAIL	generator [build failed]

After bumping otlploghttp to v0.21.0, one follow-on API break surfaced in local reproduction:

./main.go:246:21: undefined: otellog.StringValue

Using attribute.StringValue(...) at that call site resolved it.

Verification

• Ran in a local copy of the PR module state:
  • go test ./... with PR deps: fails with otlploghttp@v0.19.0 undefined API symbols.
  • go test ./... after applying both remediations above: passes (generator [no test files]).
• Checked open flaky-test issues scoped to otlp_input_otel; no directly readable matching issue was returned.

Follow-up

If you want to avoid this class of failure in future Dependabot bumps, consider grouping all go.opentelemetry.io/otel/* log-related modules in the same update set so their minor versions stay aligned.
