Upgrade Notes

• ddtrace.contrib.gevent

  • GeventContextProvider can now return and activate None, Span or Context objects.

• ddtrace.contrib.tornado

  • TracerStackContext can now return and activate None, Span or Context objects.

• ddtrace.context.Context no longer maintains the active/current span state.

  • get_current_root_span() has been removed. Use tracer.current_root_span() instead.

  • get_current_span() has been removed. Use tracer.current_span() instead.

  • add_span() has been removed. To activate a span in an execution use tracer.context_provider.activate() instead.

  • active() now returns None, Span or Context objects.
  • activate() now accepts None, Span or Context objects.

• ddtrace.tracer.Tracer
