Bug Fixes

• CI Visibility: This fix resolves an issue where a failure response from the /search_commits endpoint caused the git metadata upload to fall back to sending the full 30-day commit history instead of aborting. This fallback could trigger cascading write load on the backend. The upload now aborts when search_commits fails, matching the behavior when the /packfile upload itself fails.

• ai_guard: This fix resolves a conflict between ddtrace.auto and strands when imported in the same file, which left Strands hooks silently disabled. The Strands integration now loads lazily on first attribute access so its event class identities match those the agent dispatches.

• AAP: This fix resolves an issue where Application and API Protection (AAP) was incorrectly reported as an enabled product in internal telemetry for all services by default. Previously, registering remote configuration listeners caused AAP to be reported as activated even when it was not actually enabled. This had no impact on customers as it only affected internal telemetry data. AAP is now only reported as activated when it is explicitly enabled or enabled through remote configuration.

• iast: A crash has been fixed.

• profiling: A crash that could happen in child processes after fork has been fixed.

• tracing: This fix resolves a memory leak where reference cycles through a span's properties were invisible to Python's cyclic garbage collector and accumulated proportionally to traced call volume.

• internal: A crash has been fixed.

• LLM Observability: Fixes incorrect span hierarchy in LLMObs traces when using the ddtrace SDK alongside OTel-based instrumentation (e.g. Strands Agents). OTel gen_ai spans (e.g. invoke_agent) were incorrectly appearing as siblings of their SDK parent span (e.g. call_agent) rather than being nested under it.

• profiling: A rare crash occurring when profiling asyncio code with many tasks or deep call stacks has been fixed.

• profiling: A bug in Lock Profiling that could cause crashes when trying to access attributes of custom Lock subclasses (e.g. in Ray) has been fixed.

• profiling: A race condition which could make asyncio code raise exceptions at exit has been fixed.

• serverless: AWS Lambda functions now appear under their function name as the service when DD_SERVICE is not explicitly configured. Service remapping rules configured in Datadog will
  now apply correctly to Lambda spans.
