Compare Source

Added

• opentelemetry-docker-tests: Refactor Docker tests to properly validate
  contents of exported telemetry
  (#​5220)
• opentelemetry-exporter-otlp-common: add shared package for common OTLP
  utilities
  (#​5252)
• opentelemetry-sdk: add MissingDependencyError exception for declarative
  configuration and use it for missing optional dependency errors
  (#​5265)
• opentelemetry-sdk: Add ability to refresh process dependent Resource
  attributes
  (#​5280)
• opentelemetry-sdk: add force_flush method to LogRecordExporter ABC
  (#​5294)
• opentelemetry-sdk: Make it possible to limit the size of stored spans in
  InMemorySpanExporter
  (#​5296)
• opentelemetry-sdk: add log record limits environment variables
  OTEL_LOGRECORD_ATTRIBUTE_COUNT_LIMIT and
  OTEL_LOGRECORD_ATTRIBUTE_VALUE_LENGTH_LIMIT
  (#​5300)
• opentelemetry-sdk: add support for file exporter with declarative config
  (#​5311)
• opentelemetry-sdk: expose SynchronousMultiLogRecordProcessor and
  ConcurrentMultiLogRecordProcessor publicly
  (#​5327)
• opentelemetry-sdk: point the declarative configuration package README at
  the shared language support status
  matrix
  in the opentelemetry-configuration repo, so Python conformance status lives
  alongside the other languages instead of being duplicated per language SDK.
  (#​5347)
• opentelemetry-sdk: document that Python-implementation extensions
  (OTEL_PYTHON_* variables) are bypassed when OTEL_CONFIG_FILE is set. The
  env-var initialisation path is skipped entirely in favour of the declarative
  file; honouring these alongside a config file is tracked as a follow-up.
  (#​5353)
• opentelemetry-sdk: wire id_generator from declarative configuration to
  TracerProvider
  (#​5363)
• opentelemetry-sdk: Add support for activating instrumentors from a
  declarative configuration file via the instrumentation/development.python
  section. Instrumentors can declare a configuration attribute to have their
  options validated through the same type-coercion pipeline used for SDK
  component configuration.
  (#​5372)
• opentelemetry-sdk: add record_min_max option to
  ExponentialBucketHistogramAggregation, matching the option already
  available on ExplicitBucketHistogramAggregation and required by the
  specification
  (#​5377)

Changed

• opentelemetry-sdk: revert BoundedAttributes RLock back to Lock
  (#​5329)
• docs: update logs example to use opentelemetry-instrumentation-logging
  (#​5344)
• opentelemetry-sdk: bump declarative configuration schema to v1.1.0
  (#​5345)
• opentelemetry-configuration: declarative configuration moves from
  opentelemetry.sdk._configuration into the new public
  opentelemetry-configuration package (opentelemetry.configuration
  namespace), published experimentally. opentelemetry-sdk[file-configuration]
  continues to work as an alias that installs opentelemetry-configuration
  alongside the SDK.
  (#​5356)
• opentelemetry-api: remove env carrier environment snapshot caching, you now
  have to pass explicitly the mapping where to get the environment variables
  from as the EnvironmentGetter.get first argument.
  (#​5366)
• opentelemetry-semantic-conventions: bump to 1.42.0
  (#​5410)
• opentelemetry-semantic-conventions: bump to 1.43.0
  (#​5413)

Removed

• opentelemetry-api, opentelemetry-sdk: Removed deprecated Events API/SDK.
  Use LogRecord with the event_name field set instead.
  (#​5293)

Fixed

• opentelemetry-sdk: Optimize LogRecord memory in BatchLogRecordProcessor
  by clearing the Context object before buffering. This is a potentially
  breaking change for custom log exporters that access context from the
  exported ReadableLogRecord, as the context will now be an empty Context()
  instead of the original.
  (#​4977)
• opentelemetry-sdk: drop non-finite measurements (NaN and Inf) at the
  instrument level to prevent permanent aggregation poisoning
  (#​5336)
• opentelemetry-sdk: raise ValueError when
  ExplicitBucketHistogramAggregation boundaries are not strictly increasing
  or finite
  (#​5340)
• opentelemetry-sdk: ProcessResourceDetector no longer collects or emits
  process.command_args and process.command_line by default since the values
  are not sanitized and may contain sensitive information. Users who depend
  on these resource attributes must pass include_command_args=True.
  (#​5364)
• opentelemetry-exporter-otlp-proto-http: fix the OTLP HTTP metric exporter
  self-observability metrics over-counting data points when
  max_export_batch_size splits a batch; each split now reports its own
  data-point count instead of the whole-batch count.
  (#​5370)
• opentelemetry-api: Prevent in-place mutation of Context via inherited
  dict methods
  (#​5399)

  (#​5251)
• opentelemetry-sdk: add ServiceInstanceIdResourceDetector for populating
  service.instance.id
  (#​5259)
• opentelemetry-sdk: declarative config loader now recursively converts
  parsed dicts into typed dataclass instances, including nested dataclasses,
  lists of dataclasses, and enum values. End-to-end YAML/JSON → SDK
  configuration now works via the factory functions.
  (#​5269)
• opentelemetry-sdk: add configure_sdk(config) to the declarative
  configuration API. Single entry point that takes a parsed
  OpenTelemetryConfiguration, builds the resource, and applies the
  tracer/meter/logger providers and propagator globally. Honors the top-level
  disabled flag.
  (#​5270)
• opentelemetry-sdk: the SDK configurator now honors the OTEL_CONFIG_FILE
  environment variable. When set, the SDK loads and applies the referenced
  declarative configuration file (YAML or JSON) in place of the env-var-based
  init path.
  (#​5271)
• opentelemetry-sdk: update declarative config to use
  ServiceInstanceIdResourceDetector
  (#​5299)
• opentelemetry-exporter-otlp-proto-common,
  opentelemetry-exporter-otlp-json-common: encoders now always accept null,
  and encode it as an empty AnyValue in accordance with the spec.
  (#​5305)
• opentelemetry-sdk: validate the declarative config file_format version —
  reject an unsupported major version and warn on a newer minor version, per
  the configuration spec versioning rules
  (#​5315)

• [BREAKING] Remove LogData and extend SDK LogRecord to have instrumentation scope
  (#​4676)

• [BREAKING] Rename several classes from Log to LogRecord
  (#​4647)

  Migration Guide:

  LogData has been removed. Users should update their code as follows:

  • For Log Exporters: Change from Sequence[LogData] to Sequence[ReadableLogRecord]

    # Before
    from opentelemetry.sdk._logs import LogData
    def export(self, batch: Sequence[LogData]) -> LogRecordExportResult:
        ...
    
    # After
    from opentelemetry.sdk._logs import ReadableLogRecord
    def export(self, batch: Sequence[ReadableLogRecord]) -> LogRecordExportResult:
        ...

  • For Log Processors: Use ReadWriteLogRecord for processing, ReadableLogRecord for exporting

    # Before
    from opentelemetry.sdk._logs import LogData
    def on_emit(self, log_data: LogData):
        ...
    
    # After
    from opentelemetry.sdk._logs import ReadWriteLogRecord, ReadableLogRecord
    def on_emit(self, log_record: ReadWriteLogRecord):
        # Convert to ReadableLogRecord before exporting
        readable = ReadableLogRecord(
            log_record=log_record.log_record,
            resource=log_record.resource or Resource.create({}),
            instrumentation_scope=log_record.instrumentation_scope,
            limits=log_record.limits,
        )
        ...

  • Accessing log data: Use the same attributes on ReadableLogRecord/ReadWriteLogRecord

    • log_record.log_record - The API LogRecord (contains body, severity, attributes, etc.)
    • log_record.resource - The Resource
    • log_record.instrumentation_scope - The InstrumentationScope (now included, was in LogData before)
    • log_record.limits - The LogRecordLimits

• Mark the Events API/SDK as deprecated. The Logs API/SDK should be used instead, an event is now a LogRecord with the event_name field set
  (#​4654).

• Fix type checking for built-in metric exporters
  (#​4820)

• logs: extend Logger.emit to accept separated keyword arguments
  (#​4737)

  (#​4691)
• Update OTLP gRPC/HTTP exporters: calling shutdown will now interrupt exporters that are sleeping
  before a retry attempt, and cause them to return failure immediately.
  Update BatchSpan/LogRecordProcessors: shutdown will now complete after 30 seconds of trying to finish
  exporting any buffered telemetry, instead of continuing to export until all telemetry was exported.
