Ddtrace

Bug Fixes

- Fixed the support for Celery workers that fork sub-processes with Python 3.6 and earlier versions.
- Fixes cases in which the `test.status` tag of a test span from `pytest` would be missing because `pytest_runtest_makereport` hook is not run, like when `pytest` has an internal error.
- Pin `protobuf` version to `<3.18` for Python \<=3.5 due to support being dropped.

Upgrade Notes

- Replace DD_TRACER_PARTIAL_FLUSH_ENABLED with DD_TRACE_PARTIAL_FLUSH_ENABLED Replace DD_TRACER_PARTIAL_FLUSH_MIN_SPANS with DD_TRACE_PARTIAL_FLUSH_MIN_SPANS

Deprecation Notes

- The DD_TRACER_PARTIAL_FLUSH_ENABLED and DD_TRACER_PARTIAL_FLUSH_MIN_SPANS environment variables have been deprecated and will be removed in version 1.0 of the library.

New Features

- The `ddtrace.Tracer.get_log_correlation_context` method has been added to replace `ddtrace.helpers.get_correlation_ids`. It now returns a dictionary which includes the current span's trace and span ids, as well as the configured service, version, and environment names.
- The gevent tasks are now tracked by the threading lock events

Bug Fixes

- Fixes an issue where a manually set `django.request` span resource would get overwritten by the integration.
- Pin `setup_requires` dependency `setuptools_scm[toml]>=4,<6.1` to avoid breaking changes.
- The profiler now updates the trace resource when capturing span information with the stack and lock collectors. That means that if the trace resource changes after the profiling events are created, the profiler samples will also be updated. This avoids having trace resource being empty when profiling, e.g., WSGI middleware.

Deprecation Notes

- Removed the `collect_metrics` argument from `Tracer.configure`. See the release notes for v0.49.0 for the migration instructions.

New Features

- Add tracing support for the `httpx` library. Supported versions `>=0.14.0`.

- ASGI: store the ASGI span in the scope. The span can be retrieved with the
`ddtrace.contrib.asgi.span_from_scope` function.

- Submit runtime metrics as distribution metrics instead of gauge metrics.

- Support flask-caching (\>= 1.10.0) with the Flask-Cache tracer.

- Only for CI Visibility (<span class="title-ref">pytest</span> integration): It is now possible to specify any of the following git metadata through environment variables:
- \`DD_GIT_REPOSITORY_URL\`: The url of the repository where the code is stored
- \`DD_GIT_TAG\`: The tag of the commit, if it has one
- \`DD_GIT_BRANCH\`: The branch where this commit belongs to
- \`DD_GIT_COMMIT_SHA\`: The commit hash of the current code
- \`DD_GIT_COMMIT_MESSAGE\`: Commit message
- \`DD_GIT_COMMIT_AUTHOR_NAME\`: Commit author name
- \`DD_GIT_COMMIT_AUTHOR_EMAIL\`: Commit author email
- \`DD_GIT_COMMIT_AUTHOR_DATE\`: The commit author date (ISO 8601)
- \`DD_GIT_COMMIT_COMMITTER_NAME\`: Commit committer name
- \`DD_GIT_COMMIT_COMMITTER_EMAIL\`: Commit committer email
- \`DD_GIT_COMMIT_COMMITTER_DATE\`: The commit committer date (ISO 8601)

Bug Fixes

- ASGI: handle decoding errors when extracting headers for trace propagation.

- Corrected some typing annotations for PEP 484 compliance

- Django: add support for version 3.1+ ASGI applications. A different codepath is taken for requests starting in Django 3.1 which led to the top level span not being generated for requests. The fix introduces automatic installation of the ASGI middleware to trace Django requests.

- dogpile.cache: handle both kwargs and args in the wrapper functions (using
only kwargs would result in an IndexError.

- Fixes an issue with the Django integration where if the `urlconf` changes at any point during the handling of the request then the resource name will only be `<METHOD> 404`. This fix moves resource name resolution to the end of the request.

- Fixes error with tagging non-string Flask view args.

- `werkzeug.exceptions.NotFound` 404 errors are no longer raised and logged as a server error in the Flask integration.

- Fixes type hinting for `**patch_modules` parameter for `patch`/`patch_all` functions.

- Fixes an issue when using the pytest plugin with doctest which raises an `AttributeError` on `DoctestItem`.

- Fixes a bug in the pytest plugin where xfail test cases in a test file with a module-wide skip raises attribute errors and are marked as xfail rather than skipped.

- Fixed the handling of sanic endpoint paths with non-string arguments.

- opentracer: don't override default tracing config for the <span class="title-ref">ENABLED</span>,
<span class="title-ref">AGENT_HOSTNAME</span>, <span class="title-ref">AGENT_HTTPS</span> or <span class="title-ref">AGENT_PORT</span> settings.
