0.49.0

Release Notes

v0.49.0

Prelude

Several deprecations have been made to Context as we prepare to move active span management out of this class.

New Features

• The futures integration is now enabled by default.
• requests: add global config support. This enables the requests service name to be configured with ddtrace.config.requests['service'] or the DD_REQUESTS_SERVICE environment variable.

Upgrade Notes

• Support for aiohttp previous to 2.0 has been removed.
• Support for deprecated DD_PROFILING_API_URL environment variable has been removed. Use DD_SITE instead.
• Support for deprecated DD_PROFILING_API_KEY environment variable has been removed. Use DD_API_KEY instead.
• Profiling support for agentless mode must now be explicitly enabled.
• The ddtrace pytest plugin can now label spans from test cases marked xfail with the tag "pytest.result" and the reason for being marked xfail under the tag "pytest.xfail.reason".
• requests: spans will no longer inherit the service name from the parent.
• The return value of Span.pprint() has been changed to a single line in the tracer debug logs rather than the previous custom multiline format.
• Spans are now processed per tracer instance. Formerly spans were stored per-Context which could be shared between tracer instances. Note that context management is not affected. Tracers will still share active spans.
• Spans from asynchronous executions (asyncio, gevent, tornado) will now be processed and flushed together. Formerly the spans were handled per-task.
• tracer.write() will no longer have filters applied to the spans passed to it.
• The function ddtrace.utils.merge_dicts has been removed.

Deprecation Notes

• Context.clone is deprecated. It will not be required in 0.50.

• Context.add_span is deprecated and will be removed in 0.50.

• Context.add_span is deprecated and will be removed in 0.50.

• Context.close_span is deprecated and will be removed in 0.50.

• Context.get_current_span is deprecated and will be removed in 0.50 please use Tracer.current_span instead.

• Context.get_current_root_span is deprecated and will be removed in 0.50 please use Tracer.current_root_span instead.

• Deprecate the configuration of the analytics through the generic dbapi2 configuration. This should now be configured via integration configurations, for example:

  # Before
  export DD_TRACE_DBAPI2_ANALYTICS_ENABLED=1
