Sourced from azure-core's releases.

azure-core_1.34.0

1.34.0 (2025-05-01)

Features Added

• Added a set_span_error_status method to the OpenTelemetryTracer class. This method allows users to set the status of a span to ERROR after it has been created. #40703

Other Changes

• Python 3.8 is no longer supported. Please use Python version 3.9 or later.

azure-core_1.33.0

1.33.0 (2025-04-03)

Features Added

• Added native OpenTelemetry tracing to Azure Core which enables users to use OpenTelemetry to trace Azure SDK operations without needing to install a plugin. #39563
  • To enable native OpenTelemetry tracing, users need to:
    1. Have opentelemetry-api installed.
    2. Ensure that settings.tracing_implementation is not set.
    3. Ensure that settings.tracing_enabled is set to True.
  • If setting.tracing_implementation is set, the tracing plugin will be used instead of the native tracing.
  • If settings.tracing_enabled is set to False, tracing will be disabled.
  • The OpenTelemetryTracer class was added to the azure.core.tracing.opentelemetry module. This is a wrapper around the OpenTelemetry tracer that is used to create spans for Azure SDK operations.
  • Added a get_tracer method to the new azure.core.instrumentation module. This method returns an instance of the OpenTelemetryTracer class if OpenTelemetry is available.
  • A TracingOptions TypedDict class was added to define the options that SDK users can use to configure tracing per-operation. These options include the ability to enable or disable tracing and set additional attributes on spans.
    • Example usage: client.method(tracing_options={"enabled": True, "attributes": {"foo": "bar"}})
  • The DistributedTracingPolicy and distributed_trace/distributed_trace_async decorators now uses the OpenTelemetry tracer if it is available and native tracing is enabled.
    • SDK clients can define an _instrumentation_config class variable to configure the OpenTelemetry tracer used in method span creation. Possible configuration options are library_name, library_version, schema_url, and attributes.
    • DistributedTracingPolicy now accepts a instrumentation_config keyword argument to configure the OpenTelemetry tracer used in HTTP span creation.

Breaking Changes

• Removed automatic tracing enablement for the OpenTelemetry plugin if opentelemetry was imported. To enable tracing with the plugin, please import azure.core.settings.settings and set settings.tracing_implementation to "opentelemetry". #39563
• In DistributedTracingPolicy, the default span name is now just the HTTP method (e.g., "GET", "POST") and no longer includes the URL path. This change was made to converge with the OpenTelemetry HTTP semantic conventions. The full URL is still included in the span attributes.
• Renamed span attributes in DistributedTracingPolicy:
  • "x-ms-client-request-id" is now "az.client_request_id"
  • "x-ms-request-id" is now "az.service_request_id"

Bugs Fixed

• Fixed an issue where the traceparent header was not being set correctly in the DistributedTracingPolicy. The traceparent header will now set based on the context of the HTTP client span. #40074

Other Changes

• Added opentelemetry-api as an optional dependency for tracing. This can be installed with pip install azure-core[tracing]. #39563
