fix(profiling): track running asyncio loop if it exists #15120

KowalskiThomas · 2025-11-03T13:57:31Z

Description

https://datadoghq.atlassian.net/browse/PROF-12842

This PR updates the wrapping and thread-registering logic for the Profiler in order to track the running loop when it exists.

This is needed because otherwise, importing/starting the Profiler after starting a Task (or a loop more generally) will make us blind to the existing running loop.
Currently, we wrap the asyncio.set_event_loop function to capture when the Event Loop is first set (or is swapped). However, if the _asyncio module that sets up wrapping is imported/executed after the loop has been set, we will miss that first call to set_event_loop and be blind to asyncio Tasks until the Event Loop is changed (which in many cases never happens).

Note that we also need to execute the "find loop and track it" logic when we start the Profiler generally speaking, as in this case we may have tried (earlier) to call track_event_loop but that would have failed as no thread was registered in the Profiler.

I added four tests that account for various edge cases. Unfortunately, currently, two of them fail (marked them as xfail) and there is no way to correctly fix them. The issue is that we can only get the current running loop and not the current (non-running) event loop.
In other words, if an event loop is created and set in asyncio, and immediately after the Profiler is started without a Task having first been started, we will not be able to see that loop from the initialisation code and we will thus not be able to observe it from the Profiler thread.

In short, what works is the most common case:

✅ Import Profiler, start Profiler, start Tasks
✅ Import Profiler, start Tasks (from within the Tasks)
🚫 Import Profiler, create (non running) event loop, start Profiler, start Task
🚫 Import Profiler, create (non running) event loop, create Task, start Profiler

It is OK to start with that as I really consider the latter two to be edge cases.

Example: today we miss all asyncio data with the following code

# 0. Profiler is NOT imported here, no watching is set up
import os
import asyncio


async def my_coroutine(n):
    await asyncio.sleep(n)

# 0. Function is defined, not run, Profiler is still not imported
async def main():
    # 3. We get here, import the Profiler module (and _asyncio as well)
    #    We also start watching for set_event_loop_calls – we don't see the existing loop
    from ddtrace.profiling import Profiler

    prof = Profiler()
    prof.start()  # Should be as early as possible, eg before other imports, to ensure everything is profiled

    EXECUTION_TIME_SEC = int(os.environ.get("EXECUTION_TIME_SEC", "2"))

    t = asyncio.create_task(my_coroutine(EXECUTION_TIME_SEC / 2))
    await asyncio.gather(t, my_coroutine(EXECUTION_TIME_SEC))

    # 4. Interestingly, we detect a set_event_loop call here, but it's
    #    being set to None before exiting


# 1. This is executed first
if __name__ == "__main__":
    # 2. This implicitly creates and set the Event Loop
    asyncio.run(main())

Testing

I have tested this in prof-correctness (initially just replicated that it did not work) and it now works as expected. I will be adding more correctness tests, one with a "top of file" import and Profiler start, one with a "top of file import" and "in-code Profiler start", and one with both an "in-code file import" and "in-code Profiler start".

I also added four new tests to make sure we catch different edge cases with order of imports and order of task/profiler starts. Currently, two of them are marked as XFAILED because there is no way to reliably make them pass.

I know you've already checked that this works on some example app or service, but would it be too hard to add a regression test for this using the sample code you put together?

Oh yes, good point. I was planning to add one but then I got carried away and forgot. Will do 🙏

KowalskiThomas · 2025-11-03T17:24:06Z

Okay I wasn't able to run my test locally yet and it's failing in the CI. I'll fix and merge tomorrow! 🙇
