chore(deps): bump ddtrace from 3.17.2 to 3.18.1

[dependabot]

Bumps ddtrace from 3.17.2 to 3.18.1.

Release notes

Sourced from ddtrace's releases.

3.18.1

Estimated end-of-life date, accurate to within three months: 08-2026 See the support level definitions for more information.

Bug Fixes

• CI Visibility: this fix resolves an issue where repo tags would be fetched while unshallowing to extract commit metadata, causing performance issues for repos with a large number of tags.

• LLM Observability: fix support for HTTPS_PROXY.

• Error Tracking: Modifies the way exception events are stored such that the exception id is stored instead of the exception object, to prevent TypeErrors with custom exception objects.

3.18.0

Estimated end-of-life date, accurate to within three months: 08-2026 See the support level definitions for more information.

Upgrade Notes

• openai: Streamed chat/completions will no longer have token counts computed using the tiktoken library, and instead
  will default to having their token counts estimated if not explicitly provided in the OpenAI response object. To guarantee accurate streamed token metrics, set stream_options={"include_usage": True} in the OpenAI request.

Deprecation Notes

• tracing
  • Span.set_struct_tag is deprecated and will be removed in v4.0.0 with no direct replacement.
  • Span.get_struct_tag is deprecated and will be removed in v4.0.0 with no direct replacement.
  • Span.set_tag_str is deprecated and will be removed in version 4.0.0. As an alternative to Span.set_tag_str, you can use Span.set_tag instead.
• profiling: The V1 stack profiler is deprecated and will be removed in 4.0. V2 has been enabled by default since v2.20.0. DD_PROFILING_STACK_V2_ENABLED=false will no longer have an effect starting in 4.0.

New Features

• AAP
  • API Security schema collection is now supported in AWS Lambda behind an Application Load Balancer or the Lambda Function URL service where the endpoint cannot be reliably known. API Security reuses the endpoint inferred by the trace resource renaming feature or recomputes it when it is not available to perform sampling instead.
  • AppSec instrumentation for downstream request is now enabled by default for urllib3 and requests. It does not require enabling APM instrumentation for urllib3 anymore.
• profiling: Add support for threading.RLock (reentrant lock) profiling. The Lock profiler now tracks both threading.Lock and threading.RLock usage, providing comprehensive lock contention visibility for Python applications.
• LLM Observability
  • Previous dataset versions can be optionally pulled by passing the version argument to LLMObs.pull_dataset
  • Datasets have new properties version and latest_version to provide information on the version of the dataset that is being worked with and the latest global version of the dataset, respectively

Bug Fixes

• CI Visibility: This fix resolves performance issue affecting coverage collection for Python 3.12+
• kafka: This fix resolves an issue where only the first message in a batch was dispatched to Data Streams Monitoring (DSM) when consuming multiple Kafka messages
• langchain
  • This fix resolves an issue where auto instrumented prompt templates incorrectly included a version field. The version field is now omitted unless explicitly set by the user.
  • Fixes an issue where streamed responses that end before the first chunk is received would result in an IndexError.
• LLM Observability
  • Corrected the description of the assessment argument in submit_evaluation(). assessment now refers to whether the evaluation itself passes or fails according to your application, rather than the validity of the evaluation result.
