Bumps go.opentelemetry.io/collector/pdata from 1.57.0 to 1.66.0.

Changelog

Sourced from go.opentelemetry.io/collector/pdata's changelog.

v1.66.0/v0.160.0

🛑 Breaking changes 🛑

pkg/service: telemetry.Factory.CreateResource and telemetry.CreateResourceFunc now return (pcommon.Resource, string, error) instead of (pcommon.Resource, error) to expose the resource's schema URL. (#15129) The telemetry.Factory interface is experimental and cannot be implemented externally (it has an unexported method). Callers using telemetry.WithCreateResource must update the function signature to return a third string value for the schema URL.

🚩 Deprecations 🚩

pkg/confighttp: Deprecate flat keepalive fields in client and server config in favor of the new keepalive section. (#14020) The following client configuration fields are deprecated in favor of the keepalive section:

idle_conn_timeout -> keepalive::idle_conn_timeout

max_idle_conns -> keepalive::max_idle_conns

max_idle_conns_per_host -> keepalive::max_idle_conns_per_host

disable_keep_alives: true -> keepalive::enabled: false The following server configuration fields are deprecated in favor of the keepalive section:

idle_timeout -> keepalive::idle_timeout

keep_alives_enabled: false -> keepalive::enabled: false Deprecated fields set in the configuration keep working exactly as before and produce a deprecation warning when the client or server is created. Setting deprecated fields together with the new keepalive section is an error. Code migrating off the deprecated fields can use the new NewDefaultKeepaliveClientConfig and NewDefaultKeepaliveServerConfig functions to build a keepalive section with the default values.

💡 Enhancements 💡

pkg/component: Add ResourceSchemaURL field to component.TelemetrySettings to expose the collector resource's schema URL to components. (#15129)

pkg/exporterhelper: Migrate TimeoutConfig to schema-based configuration generated by mdatagen. (#15505)

🧰 Bug fixes 🧰

pkg/pprofile: add bounds checks to FromLocationIndices and switchDictionary (#15697) FromLocationIndices now returns an error instead of panicking on an out-of-range or negative location index, mirroring FromAttributeIndices. The index checks used when merging profiles now also reject negative indices. These were previously reachable with a negative index decoded from an OTLP payload, which panicked the collector via Profiles.MergeTo.

v1.65.0/v0.159.0
