Prelude

In preparation for the upcoming v1.0.0 release, we recommend users enable deprecation warnings after having installed ddtrace>=0.59.0,<1.0.0. See the Upgrading and deprecation warnings section for further details.

New Features

  • Add environment variable DD_TRACE_RAISE_DEPRECATIONWARNING to raise library deprecation warnings as errors for those unable to configure warning filters otherwise.

  • Add Span.get_tags and Span.get_metrics.

  • aiohttp: add client integration. This integration traces requests made using the aiohttp client and includes support for distributed tracing. See the documentation for more information.

  • aiohttp_jinja2: move into new integration. Formerly the aiohttp_jinja2 instrumentation was enabled using the aiohttp integration. Use patch(aiohttp_jinja2=True) instead of patch(aiohttp=True). To support legacy behavior patch(aiohttp=True) will still enable aiohttp_jinja2.

  • fastapi: add support for tracing fastapi.routing.serialize_response.

    This will give an insight into how much time is spent calling jsonable_encoder within a given request. This does not provide visibility into how long it takes for Response.render/json.dumps.

  • HTTP connections for trace payloads to the agent will be reused when possible.

Deprecation Notes

  • Span.to_dict is deprecated and will be removed in v1.0.0.
  • ddtrace.Tracer.log is deprecated. Use logging.getLogger("ddtrace.tracer") instead.
  • Tracer.write() is deprecated. Writing spans to the writer through the tracer is not supported.

Bug Fixes

  • tracing/internal: fix encoding of propagated internal tags.
  • Fix issue building ddtrace from source on macOS 12.
  • Fixes wrong numbers of memory allocation being reported in the memory profiler.
  • pymongo: fix write_command being patched with the wrong method signature.

Other Notes

  • tracing/internal: disable Datadog internal tag propagation
