chore(tracer): add span info to _start_span_after_shutdown warning by mabdinur · Pull Request #16336 · DataDog/dd-trace-py

mabdinur · 2026-02-03T21:25:59Z

Description

Includes the span's name, parent_id, and trace_id in tracer shutdown warnings to make debugging missing spans easier.
Moves typing and docs from _start_span to start_span for clarity and fixes a typing error (_start_span = start_span).

Testing

Updated tracer shutdown test cases to ensure warning is logged for both tracer.start_span and tracer.trace

Risks

None
