feat(profiling): profile `threading.Semaphore` primitives with Python Lock profiler by vlad-scherbich · Pull Request #15327 · DataDog/dd-trace-py

Description

This PR adds profiling support for threading.Semaphore to the Lock Profiler, including critical double-counting prevention when multiple lock collectors are active simultaneously.

What

Add ThreadingSemaphoreCollector: New collector for profiling threading.Semaphore usage
Prevent double-counting: Detect and skip profiling stdlib-internal locks to avoid duplicate samples
Proper stack attribution: Ensure stack traces point to user code, not threading.py internals

Why

Without direct Semaphore profiling:

Stack traces attribute operations to threading.py internals (e.g., Condition.__enter__ at line 502)
Flame graphs show stdlib code instead of application code
Performance bottlenecks are obscured and unusable for debugging

The double-counting problem:

# When both ThreadingLockCollector and ThreadingSemaphoreCollector are active:
sem = threading.Semaphore(1)  # User creates semaphore
# Internally: Semaphore → Condition → Lock (3 wrapped objects!)
sem.acquire()  # Would generate 2 samples: Semaphore + internal Lock (INSTEAD of 1!)

Without prevention, one user operation generates multiple profile samples, making metrics inaccurate.

Changes

1. New Semaphore Collector (ddtrace/profiling/collector/threading.py)
2. Double-Counting Prevention (ddtrace/profiling/collector/_lock.py)
3. Drive-by fixes (tests/profiling_v2/collector/test_threading.py)

added type annotations
renamed type aliases for clarity

Testing

New Unit Tests

Test user code is attributed, and not that of internal libs: test_stack_trace_points_to_user_code
Test internal locks are marked: test_internal_lock_marked_correctly
Test double-counting prevention: test_no_double_counting_with_lock_collector

note: location of manual test scripts: https://github.com/DataDog/dd-trace-py/compare/vlad/proflock-semaphores-demo?expand=1

UI: BEFORE

Flame graph -- shows internal lib locks in threading.py:

threading.py:401:_lock in Semaphore.wait_for method (its internal Lock member)

UI: AFTER

Flamegraph -- shows actual threading.Semaphore name from user code:

connection_pool_semaphore

Implementation Notes

Flame graphs show clean attribution to application code.
The Semaphore → Condition → Lock chain is not visible
Why use Frame 2, Not Frame 1?

Frame 0: _profiled_allocate_lock (currently executing)
Frame 1: _LockAllocatorWrapper.__call__ (the wrapper)
Frame 2: actual caller (user code OR threading.py) ← We inspect this!

Performance Impact

Extra ~8 bytes per lock for the new __slots__ field (~8% increase from optimized version)
Lock creation: +1 sys._getframe(2) call, +1 path comparison (one-time per lock)
Hot path (acquire/release): +1 if self.is_internal check (negligible)

Risk

Low: new profiled type added, existing are unmodified
Low: edge cases in is_internal detection (mitigated by testing)
