Bumps ddtrace from 4.8.2 to 4.15.6.

Release notes

Sourced from ddtrace's releases.

4.15.6

Security Issues

• tracing: Fixes a security vulnerability, as described in GHSA-3633-r77q-h3v3.

4.15.5

Bug Fixes

• Code Security (IAST): fixes an issue where taint tracking could abort the Python process when old-style % string formatting handled tainted text containing a lone surrogate character.

4.15.4

Bug Fixes

• internal: Fixes an issue on macOS where starting a subprocess can deadlock while a hostname lookup is in progress.
• tracing: Fixes a native memory leak on Linux when DD_TRACE_OTEL_CTX_ENABLED is set to true and a thread exits while an OpenTelemetry thread context is still attached.

4.15.3

Bug Fixes

• LLM Observability:
  • Resolves an issue where a streamed Bedrock InvokeModelWithResponseStream request that ended in an error or was cancelled part-way produced a span with no output annotation. The text received before the failure is now tagged on the span.
  • Resolves an issue where a streamed Bedrock ConverseStream request that ended in an error or was cancelled part-way produced a span that was not marked as an error, making an interrupted request indistinguishable from a successful one.
  • This fix resolves an issue where cancelled or failed OpenAI streamed requests produced no LLM Observability span at all. These requests now produce an LLM span carrying the input messages, whatever output arrived before the stream ended, and estimated token metrics.
• internal:
  • Fixes incorrect telemetry being collected when hitting cardinality limits during stats computation.
• tracing:
  • Fixes an issue where the Python garbage collector stops and memory grows without limit when DD_RUNTIME_METRICS_ENABLED is true.
• Profiling:
  • A crash that could occur in applications that use signal handlers to recover from crashes has been fixed.

4.15.2

Upgrade Notes

• tracing: DD_TRACE_OTEL_CTX_ENABLED now defaults to false until a Linux-native memory leak caused by setting it to true is fixed.

Bug Fixes

• LLM Observability: Fixes an issue where abandoned or disconnected streamed LLM requests can leave spans unfinished, causing memory to grow in long-running web workers.
• CI Visibility: Fixes an issue where Auto Test Retries do not retry tests that use pytest-timeout thread mode and terminate a pytest-xdist worker.

4.15.1

Bug Fixes

• LLM Observability
  • Resolves an issue where gen_ai.* attributes were added to APM spans when LLM Observability was disabled. These attributes are now only emitted when LLM Observability is enabled.

4.15.0

Estimated end-of-life date, accurate to within three months: 05-2027
