feat(profiling): [unwrapt] remove `wrapt` dependency from Lock Profiler #15003

vlad-scherbich · 2025-10-23T15:14:05Z

https://datadoghq.atlassian.net/browse/PROF-12854

Description

This PR removes wrapt dependency from lock profiler - replaced with direct delegation. It implements the following proposal in the Lock Profiler RFC: Remove wrapt dependency

Why

Reduce overhead on each lock create / acquire / release
Simpler code, no external dependency
Consistent behavior (no more WRAPT_C_EXT detection - wrapt's compiled C extension vs pure Python)

Changes

Replaced wrapt.ObjectProxy with internal wrapper making use of __slots__
(special class attribute that allows you to explicitly declare the data members (attributes) of a class, without using dict implicitly)
Added _LockAllocatorWrapper as protocol
Removed environment-dependent frame depth logic (2 if WRAPT_C_EXT, else 3)

Performance

Ran benchmarks with 10K locks under multi-threaded contention:

Metric	Before	After	Change
Memory	~200 bytes/lock	~100 bytes/lock	-50%
Creation	2.1 µs	1.8 µs	-14%
Acquire/Release	Variable	Consistent	+10-20%

See for details.

Lost Features

wrapt is very powerful, but is an overkill for the Lock profiler in particular. That said, here are the features we would lose, which will be easy to implement ourselves:

Automatic attribute forwarding
Transparent isinstance() checks
Introspection support (dir(), vars(), etc.)
Pickle (serialization) support
Weak reference support

Testing

All existing tests pass (updated test_patch for new behavior + removed unnecessary test)
Full benchmark results: vlad/benchmark-lock-profiler

Risks

low: existing functionality intact, as shown by unit / e2e tests and local testing
low: could break users with esoteric workflows

ddtrace/profiling/collector/_lock.py

-        # The underlying threading.Lock class is implemented using C code, and
-        # it doesn't have the __dict__ attribute. So we can't do
-        # self.__dict__.pop("_self_acquired_at", None) to remove the attribute.
-        # Instead, we need to use the following workaround to retrieve and
-        # remove the attribute.
        start: Optional[int] = getattr(self, "_self_acquired_at", None)


I see you're removed the comment – is it not applicable anymore? (I guess so!)

If so, would it make sense to use __dict__ – does it make any different performance-wise?

TL;DR - it is not appropriate anymore due use of special __slots__ attribute to store the wrapped lock's attributes (not a dict!)

details:
This comment had the right explanation, it was just incomplete. When wrapt wraps a C object, it has no dict attribte. When it wraps a Python obj - it does have dict!

So the comment was lacking this crucial detail, which makes it confusing, IMO. It should've said the following at the end:

"we need to use the following workaround to retrieve~ and remove ~the attribute."
-->
"we need to use the following workaround to retrieve the attribute due to race conditions" -- see the comment below that's explaining what happens.
