[dependabot]

Bumps go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc from 1.45.0 to 1.46.0.

Release notes

Sourced from go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc's releases.

v1.46.0/v0.68.0/v0.22.0/v0.0.19

This release is the last to support Go 1.25. The next release will require at least Go 1.26.

Added

• Support testing of Go 1.27. (#8811)
• Support http/json protocol in go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp. (#8273, #8775, #8831)
• Add Hasher struct and methods in go.opentelemetry.io/otel/attribute to compute authoritative Distinct hashes incrementally for attribute filtering and deduplication. (#8598)

Changed

• Lazily evaluate filtered and dropped attributes on measurement hot paths in go.opentelemetry.io/otel/sdk/metric to avoid unnecessary attribute set allocations. (#8598)
• Add ErrExporterShutdown to go.opentelemetry.io/otel/sdk/log and return it from the go.opentelemetry.io/otel/exporters/stdout/stdoutlog, go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc, and go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp exporters when Export is called after Shutdown. (#8773)
• Clarify in go.opentelemetry.io/otel/log that calling Logger.Enabled is optional and that cached results can become stale. (#8764)

Fixed

• Export dropped attribute counts in OTLP log records from go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc and go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp. (#8829)
• Name span events created from OpenTracing logs after the event log field, falling back to log, instead of always using an empty name in go.opentelemetry.io/otel/bridge/opentracing. (#8648)
• Count exception attributes omitted due to the attribute count limit as dropped in go.opentelemetry.io/otel/sdk/log. (#8796)
• Prevent log record and instrumentation scope attributes with empty keys from reaching processors and exporters in go.opentelemetry.io/otel/sdk/log. (#8797)
• Fix a data race when span attributes are read concurrently in go.opentelemetry.io/otel/sdk/trace. (#8706)
• Prevent a panic in (*Set).Filter when called on a nil receiver in go.opentelemetry.io/otel/attribute. (#8792)
• The simple span and log processors record otel.sdk.processor.{span,log}.processed when the record is submitted to the exporter instead of after the export completes, and no longer set error.type from the export outcome, in go.opentelemetry.io/otel/sdk/trace and go.opentelemetry.io/otel/sdk/log. (#8705)
• Prevent Resource.MarshalLog from panicking on nil resources in go.opentelemetry.io/otel/sdk/resource. (#8758)

Hi @dependabot[bot]. Thanks for your PR.

I'm waiting for a GoogleContainerTools member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
