0.41.0

Upgrading to 0.41.0

This release includes new features, performance improvements (including a custom msgpack encoder) and profiling and several bug fixes. With this release we will be building and publishing wheels for macOS and Windows.

Integrations

asgi

• Add ASGI integration! (#1567)

django

• Add option for using legacy resource format (#1551 -- thanks @tredzko, @jheld). The previous method used for the resource name was preferred by a number of users so we've added it back. See #1551 for details.

grpc

• Fix GRPC Channel Pin (#1582 -- thanks @munagekar). This will allow users to actually use the service name overriding functionality for grpc channels.

Profiler

• Reduce the default amount of sampling for memory/lock to 2% (#1586)
• Fix empty filenames (#1585)
• Fix race condition with periodic thread (#1569)
• Lock Recorder on reset (#1560)

Tracer

• Disable import hooks (#1563). These were causing some strange issues so we're disabling them until we sort out what's going on.
• Make environment variables consistent with other languages (#1575)
• Set tags from DD_TAGS (#1561).
• Add startup logging (#1548). These logs will help customers with setting up tracing. The feature can be opted out of by setting the environment variable DD_TRACE_STARTUP_LOGS=0.
• Add msgpack encoder (#1491). A large portion of CPU time spent is encoding. We've introduced a custom encoder to begin making optimizations.

0.40.0

Upgrading to 0.40.0

This release includes performance improvements in the core library, updates profiling, and configuration changes to several integrations. This release also adds support for installing on Windows.

grpc

• Use ddtrace.config.grpc["service_name"] to set service name reported by default for gRPC client instances. The DD_GRPC_SERVICE environment variable can also be used.

redis

• Use ddtrace.config.redis["service"] to set the service name for the redis integration. The environment variable DD_REDIS_SERVICE can also be used.

httplib

• To enable distributed tracing, use ddtrace.config.httplib["distributed_tracing"]. By default, distributed tracing for httplib is disabled.

Changes

Improvements

• fix(monkey): use lock on manual patched module add (#1479 -- thanks @uniq10)
• core: re-enable custom rng (#1474)
• core: rewrite queue (#1534)
• pin: make service optional (#1529)
• feat(ddtrace-run): allow to enable profiling (#1537)
• feat(profiling): enable flush on exit by default for Profiler (#1524)
• fix(grpc): compute service name dynamically (#1530)
• feat(redis): add global service configuration (#1515)
• feat(httplib): support distributed tracing (#1522 -- thanks @jirikuncar)
• refactor(profiling): hide Profiler._schedulers (#1523)
• feat(profiling): set Datadog-Container-Id when uploading profiles (#1520)
• feat(profiling/http): emit log message when server returns 400 (#1477)
• feat(profiling): validate API key format (#1459)

Bug fixes

• fix(profiling): fix memory leak in Python 2 stack collector (#1568)
• fix(profiling): disable exception profiling on Windows (#1538)
• fix(profiling/stack): fix GIL switching (#1475)

0.39.0

Deprecations

• The decode() method on our encoders located in ddtrace.encoders is scheduled to be removed in 0.40.

Integrations

Django

• Add headers tracing configuration. This will enable headers on requests to be attached as tags on request spans. This can be done by using the ddtrace.config API like so: config.django.http.trace_headers(["my-header-i-want-to-trace"]). Thanks to @JoseKilo for contributing this feature!
• Fix for a bug where we didn't handle all cases for a template name. Thanks @sibsibsib!

Elasticsearch

• Fix for a bug that causes the tracer to crash if params is None.

grpc

• Fix handling None RpcMethodHandlers

Tracer

• core: deprecate encoder decode()

Profiling

• Agent upload by default
• Now included by default with the tracing package
• Support for the DD_ENV and DD_VERSION environment variable configuration.
• A bunch of gevent fixes. See below for the details.

OpenTracing

• Support for tracer interleaving between the Datadog tracer (used in integrations) and the OpenTracing tracer provided in the library.

Deprecations

0.38.2

This patch release disables span linkage by default in the profiler which was causing some threading lock up issues in gevent. See #1488 and #1485 for the details.
