feat(profiling): support Python 3.14 #15546

taegyunkim · 2025-12-07T23:48:17Z

Description

This PR adds support for Python 3.14 in the profiler by updating it to handle CPython internal changes.

Key CPython changes addressed

_PyInterpreterFrame Structure Changes

Moved from Include/internal/pycore_frame.h to Include/internal/pycore_interpframe_structs.h
PyObject *f_executable and PyObject *f_funcobj changed to _PyStackRef type. Profilers like us now need to clear the LSB of these fields to get the PyObject*. See Use deferred reference counting in some _PyInterpreterFrame fields python/cpython#123923 for details
int stacktop field removed, replaced with _PyStackRef *stackpointer pointer. See GH-120024: Use pointer for stack pointer python/cpython#121923 (GH-120024) for details
PyObject *localsplus[1] changed to _PyStackRef localsplus[1]. See gh-117139: Convert the evaluation stack to stack refs python/cpython#118450 (gh-117139) for details

FutureObj/TaskObj Changes

Added fields: awaited_by, is_task, awaited_by_is_set in FutureObj_HEAD macro
Added struct llist_node_task_node field for linked-list storage

Asyncio Task Storage Changes

Prior to Python 3.14,

All tasks are stored in _scheduled_tasks WeakSet (exported from C extension)
Eager tasks are stored in _eager_tasks set (exported from C extension)

From Python 3.14,

Native asyncio.Tasks are stored in a linked-list (struct llist_node) per thread and per interpreter
- Per-thread: tstate->asyncio_tasks_head (in _PyThreadStateImpl)
- Per-interpreter: interp->asyncio_tasks_head (for lingering tasks)
- Each TaskObj has a task_node field with next and prev pointers
Third-party tasks: Still stored in Python-level _scheduled_tasks WeakSet (now Python-only, not exported from C extension)
Eager tasks: Still stored in Python-level _eager_tasks set

Implementation Summary

Frame reading (frame.h, frame.cc): Updated header includes to use pycore_interpframe_structs.h for Python 3.14+. Implemented tagged pointer handling: clear LSB of f_executable to recover PyObject* (per gh-123923). Replaced stacktop field access with stackpointer pointer arithmetic for stack depth calculation. Updated PyGen_yf() to use _PyStackRef and stackpointer[-1] instead of localsplus[stacktop-1]. Added handling for FRAME_OWNED_BY_INTERPRETER frame type (introduced in 3.14).
Task structures (cpython/tasks.h): Added Python 3.14+ FutureObj_HEAD macro with new fields: awaited_by, is_task, awaited_by_is_set. Added struct llist_node task_node field to TaskObj for linked-list storage. Updated PyGen_yf() implementation to handle _PyStackRef and stackpointer instead of stacktop.
Asyncio discovery (tasks.h, threads.h): Implemented get_tasks_from_linked_list() to safely iterate over circular linked-lists with iteration limits (MAX_ITERATIONS = 2 << 15). Added get_tasks_from_thread_linked_list() to read tasks from _PyThreadStateImpl.asyncio_tasks_head (per-thread active tasks). Added get_tasks_from_interpreter_linked_list() to read lingering tasks from PyInterpreterState.asyncio_tasks_head (per-interpreter). Updated get_all_tasks() to handle both linked-list (native asyncio.Task instances) and WeakSet (third-party tasks).
Python integration (_asyncio.py): Added compatibility handling for BaseDefaultEventLoopPolicy → _BaseDefaultEventLoopPolicy rename in 3.14. Updated _scheduled_tasks access to handle Python-only WeakSet (no longer exported from C extension in 3.14+).

Testing

All existing tests pass except for tests/profiling/collector/test_memalloc.py which needed some edits.

Overall LGTM, I think we should just make it clear what the expectation is with regards to Generator Frames.

I refactored the code a bit to keep the original address of PyThreadState struct and pass that down to copy over the asyncio_tasks_head from _PyThreadStateImpl

This fixed the issue of slowdown in asyncio tests.

## Description For [feat(profiling): support Python 3.14](#15546), I first gathered how we use CPython internal headers/structs, and then compared how they changed from 3.13.0 to 3.14.0. Then, generated an action plan based off on these. This PR is to have those two skills available so that we can follow similar steps when adding support for newer versions of Python, 3.15+, and free-threading Python.  ## Testing  ## Risks  ## Additional Notes
