Bug Fixes

• CI Visibility:
  • Resolved an issue where the CODEOWNERS file of the project being tested was looked up in the current working directory rather than the repository root.
• Dynamic Instrumentation:
  • Fixed an issue with a GC-based lookup for code origin resolution resulting in high performance overhead.
• Kafka:
  • Fixed an issue where a producer or consumer initialized with an unpacked config resulted in TypeError, causing a failed connection. confluent-kafka supports both unpacked and packed config; this change allows initialization with either.
• Profiling:
  • Fixed an issue in the SynchronizedSamplePool where pool could be null when calling into ddog_ArrayQueue_ functions, leading to segfaults in the uWSGI shutdown
• Tracing:
  • Fixed a bug in the sampling rule matcher where the pattern ?* was not being matched correctly for DD_TRACE_SAMPLING_RULES tags, due to it matching on spans with no tag matching the specified key.
