ddtrace 0.39.0

on Python PyPI

Deprecations

• The decode() method on our encoders located in ddtrace.encoders is scheduled to be removed in 0.40.

Integrations

Django

• Add headers tracing configuration. This will enable headers on requests to be attached as tags on request spans. This can be done by using the ddtrace.config API like so: config.django.http.trace_headers(["my-header-i-want-to-trace"]). Thanks to @JoseKilo for contributing this feature!
• Fix for a bug where we didn't handle all cases for a template name. Thanks @sibsibsib!

Elasticsearch

• Fix for a bug that causes the tracer to crash if params is None.

grpc

• Fix handling None RpcMethodHandlers

Tracer

• core: deprecate encoder decode()

Profiling

• Agent upload by default
• Now included by default with the tracing package
• Support for the DD_ENV and DD_VERSION environment variable configuration.
• A bunch of gevent fixes. See below for the details.

OpenTracing

• Support for tracer interleaving between the Datadog tracer (used in integrations) and the OpenTracing tracer provided in the library.
