  • The following modules have been moved:

  Datadog::Runtime::Cgroup -> Datadog::Core::Environment::Cgroup
  Datadog::Runtime::ClassCount -> Datadog::Core::Environment::ClassCount
  Datadog::Runtime::Container -> Datadog::Core::Environment::Container
  Datadog::Runtime::GC -> Datadog::Core::Environment::GC
  Datadog::Runtime::Identity -> Datadog::Core::Environment::Identity

  Datadog::Runtime::Socket -> Datadog::Core::Environment::Socket
  Datadog::Runtime::ThreadCount -> Datadog::Core::Environment::ThreadCount

• Profiler: NameError during initialization (#1552)

0.47.0 - 2021-03-29

Release notes: https://github.com/DataDog/dd-trace-rb/releases/tag/v0.47.0

Git diff: https://github.com/DataDog/dd-trace-rb/compare/v0.46.0...v0.47.0

Added

• Document support for httpx integration (#1396) (@HoneyryderChuck)
• Schemas to list of supported AWS services (#1415) (@tomgi)
• Branch test coverage report (#1343)

Changed

• BREAKING Separate Resolver configuration and resolution steps (#1319)

  ActiveRecord describes configuration now supports partial matching

  Partial matching of connection fields (adapter, username, host, port, database) is now allowed. Previously, only an exact match of connections fields would be considered matching. This should help greatly simplify database configuration matching, as you will only need to provide enough fields to correctly separate your distinct database connections.

  If you have a c.use active_record, describe: statement in your application that is currently not matching any connections, you might start seeing them match after this release.

  c.use active_record, describe: statements that are currently matching a connection will continue to match that same connection.

  You can refer to the expanded ActiveSupport documentation for details on how to use the new partial matchers and configuration code examples.

  Datadog::Contrib::Configuration::Resolver interface changed

  The interface for Datadog::Contrib::Configuration::Resolver has changed: custom configuration resolvers that inherit from Datadog::Contrib::Configuration::Resolver will need be changed to fulfill the new interface. See code documentation for Datadog::Contrib::Configuration::Resolver for specific API requirements.

0.40.0 - 2020-09-08

• Que integration (#1141, #1146) (@hs-bguven)
• Components#startup! hook (#1151)
• Code coverage report (#1159)
  • Every commit now has a coverage CI step that contains the code coverage report. This report can be found in the Artifacts tab of that CI step, under coverage/index.html.

Changed

• Use a single top level span for Racecar consumers (#1150) (@dasch)

Fixed

• Sinatra nested modular applications possibly leaking spans (#1035, #1145)

  • BREAKING for nested modular Sinatra applications only:

    class Nested < Sinatra::Base
    end
    
    class TopLevel < Sinatra::Base
      use Nested # Nesting happens here
    end

  • Non-breaking for classic applications nor modular non-nested applications.

  Fixes issues introduced by #1015 (in 0.35.0), when we first introduced Sinatra support for modular applications.

  The main issue we had to solve for modular support is how to handle nested applications, as only one application is actually responsible for handling the route. A naive implementation would cause the creation of nested sinatra.request spans, even for applications that did not handle the request. This is technically correct, as Sinatra is traversing that middleware, accruing overhead, but that does not aligned with our existing behavior of having a single sinatra.request span.

  While trying to achieve backwards-compatibility, we had to resort to a solution that turned out brittle: sinatra.request spans had to start in one middleware level and finished it in another. This allowed us to only capture the sinatra.request for the matching route, and skip the non-matching one. This caused unexpected issues on some user setups, specially around Sinatra middleware that created spans in between the initialization and closure of sinatra.request spans.

  This change now address these implementation issues by creating multiple sinatra.request, one for each traversed Sinatra application, even non-matching ones. This instrumentation is more correct, but at the cost of being a breaking change for nested modular applications.

  Please see #1145 for more information, and example screenshots on how traces for affected applications will look like.

• Rack/Rails span error propagation with rescue_from (#1155, #1162)

• Prevent logger recursion during startup (#1158)

• Race condition on new worker classes (#1154)

  • These classes represent future work, and not being used at the moment.

• Improvements to documentation (#1138)

Removed

• Ruby 1.9 support ended, as it transitions from Maintenance to End-Of-Life (#1137)
• GitLab status check when not applicable (#1160)
  • Allows for PRs pass all status checks once again. Before this change, a dd-gitlab/copy_to_s3 check would never leave the "Pending" status. This check tracks the deployment of a commit to an internal testing platform, which currently only happens on master branch or when manually triggered internally.

0.37.0 - 2020-06-24

Git diff: https://github.com/DataDog/dd-trace-rb/compare/v0.36.0...v0.37.0

Refactored

• Documentation improvements regarding Datadog Agent defaults (#1074) (@cswatt)
• Improvements to test suite (#1043, #1051, #1062, #1075, #1076, #1086)

Removed

• DEPRECATION: Deprecate Contrib::Configuration::Settings#tracer= (#1072, #1079)

  • The tracer: option is no longer supported for integration configuration. A deprecation warning will be issued when this option is used.

  • Tracer instances are dynamically created when ddtrace is reconfigured (through Datadog.configure{} calls).

    A reference to a tracer instance cannot be stored as it will be replaced by a new instance during reconfiguration.

    Retrieving the global tracer instance, by invoking Datadog.tracer, is the only safe mechanism to acquire the active tracer instance.

    Allowing an integration to set its tracer instance is effectively preventing that integration from dynamically retrieving the current active tracer in the future, thus causing it to record spans in a stale tracer instance. Spans recorded in a stale tracer instance will look disconnected from their parent context.

• BREAKING: Remove Pin#tracer= and DeprecatedPin#tracer= (#1073)

  • The Pin and DeprecatedPin are internal tools used to provide more granular configuration for integrations.
  • The APIs being removed are not public nor have been externally documented. The DeprecatedPin specifically has been considered deprecated since 0.20.0.
  • This removal is a continuation of #1079 above, thus carrying the same rationale.

Migration

• Remove tracer argument provided to integrations (e.g. c.use :rails, tracer: ...).
• Remove tracer argument provided to Pin or DeprecatedPin initializers (e.g. Pin.new(service, tracer: ...)).
• If you require a custom tracer instance, use a global instance configuration:

  Datadog.configure do |c|
    c.tracer.instance = custom_tracer
  end
