v0.46.0

Upgrade Notes

• elasticsearch: removed get_traced_transport method and ddtrace.contrib.elasticsearch.transport module.
• The profiler will only load tags from the DD_TAGS environment variable once at start.
• flask: Use HTTP Custom Error Codes instead of ddtrace.config.flask['extra_error_codes'].

New Features

• aiohttp: store request and response headers.
• bottle: store request and response headers.
• elasticsearch: add support for version 7.
• flask: store response headers.
• molten: store request headers.
• pyramid: store request and response headers.
• flask: store request and response headers when auto-instrumented.
• The ddtrace.profiling.auto module will warn users if gevent monkey patching is done after the profiler is auto-instrumented.
• The Profiler object can now be passed tags with the tags keyword argument.

Bug Fixes

• dbapi: avoid type error with potential non-compliance in db libraries when setting tag for row count.
• django: add legacy resource format of {handler}.
• grpc: fix wrapper for streaming response to support libraries that call an internal method directly.
• sanic: use path parameter names instead of parameter values for the resource.
• The profiler won't deadlock on fork when gevent monkey patch is enabled.
• requests: fix TracedSession when patches are not applied.

v0.45.0

Prelude

Python 3.9 wheels are now built and published to PyPI.

New Features

• botocore: added distributed_tracing configuration setting which is enabled by default.

• The ddtrace-run command now supports the following arguments:

  -h, --help
  -d, --debug enable debug mode (disabled by default)
  -i, --info print library info useful for debugging
  -p, --profiling enable profiling (disabled by default)
  -v, --version show program's version number and exit
  

It now also has friendlier error messages when used incorrectly.

• Add functionality to call gevent.monkey.patch_all() with ddtrace-run by setting the environment variable DD_GEVENT_PATCH_ALL=true. This ensures that gevent patching is done as early as possible in the application.

• botocore: inject distributed tracing data to ClientContext to trace lambda invocations.

• botocore: inject tracing data to MessageAttributes.

• The profiler now tracks the running gevent Greenlet and store it as part of the CPU and wall time profiling information.

• The profiler is now able to upload profiles to the Datadog Agent by using a Unix Domain Socket.

• It is now possible to pass a url parameter to the Profiler to specify the Datadog agent location.

• The new memory profiler for Python is now enabled by default. This improves the profiler memory consumption and performance impact. It can still be disabled by setting DD_PROFILING_MEMALLOC=0 as an environment variable.

• The profiler now uses the tracer configuration if no configuration is provided.

• pytest integration. This enables the pytest <https://pytest.org>_ runner to trace test executions.

Upgrade Notes

• Context.get() has been removed and the functionality has been rolled into Context.close_span().

• Tracer.record() has similarly been removed as it is no longer useful with Context.get() removed.

• The deprecated compatibility module ddtrace.profile has been removed.

• The profiler now uses the tracer configuration if no configuration is provided.

Deprecation Notes

• The pyddprofile wrapper is deprecated. Use DD_PROFILING_ENABLED=true ddtrace-run instead.

• The profiler does not catch uncaught exception anymore.

Bug Fixes

• core: always reset the current_span in the context.

• django: Http404 exceptions will no longer be flagged as errors

• django: add safe guards for building http.url span tag.

• aiobotocore: set span error for 5xx status codes.

• elasticsearch: set span error for 5xx status codes.

• django, DRF, ASGI: fix span type for web request spans.

• Fixes span id tagging in lock profiling.

• Fix UDS upload for profiling not using the correct path.

• Fixed an issue in profiling exporting profiles twice when forking.

• core: fix race condition in TracerTagCollector.

Other Notes

• Start-up logs are now disabled by default. To enable start-up logs use DD_TRACE_STARTUP_LOGS=true or DD_TRACE_DEBUG=true.
