Changed

• Rename Datadog::Runtime to Datadog::Core::Environment (#1570)

  As we prepare the Datadog Ruby namespace to better accommodate new products, we are moving a few internal modules to a different location to avoid conflicts.

  None of the affected files are exposed publicly in our documentation, and they are only expected to be used internally and may change at any time, even between patch releases.

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

  • Most constants from Datadog::Ext::Runtime have been moved to a new module: Datadog::Core::Environment::Ext.

• Skip CPU time instrumentation if logging gem is detected (#1557)

Fixed

• Initialize dogstatsd-ruby in single threaded mode (#1576)

  This should alleviate any existing issues with dogstatsd-ruby resource leaks.

• Do not use configured dogstatsd-ruby instance when it's an incompatible version (#1560)

• Ensure tags with special Datadog processing are consistently serialized (#1556)

• Profiler: NameError during initialization (#1552)

Refactored

• Improvements to test suite & CI (#1586)
• Improvements to documentation (#1397)
