New Features

• 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.

• Add support to reuse HTTP connections when sending trace payloads to the agent. This feature is disabled by default. Set DD_TRACE_WRITER_REUSE_CONNECTIONS=true to enable this feature.

• MySQLdb: Added optional tracing for MySQLdb.connect, using the configuration option here.

• The profiler now supports profiling asyncio.Lock objects.

• Add support for injecting and extracting B3 propagation headers.

  See DD_TRACE_PROPAGATION_STYLE_EXTRACT and DD_TRACE_PROPAGATION_STYLE_INJECT configuration documentation to enable.

Bug Fixes

• botocore: omit SecretBinary and SecretString from span metadata for calls to Secrets Manager.

• Fix issue building ddtrace for the Pyston Python implementation by not building the _memalloc extension anymore when using Pyston.

• tracer.get_log_correlation_context(): use active context in addition to
  active span. Formerly just the span was used and this would break cross execution log correlation as a context object is used for the propagation.

• opentracer: update set_tag and set_operation_name to return a
  reference to the span to match the OpenTracing spec.

• The CPU profiler now reports the main thread CPU usage even when asyncio tasks are running.
