Summary

Peels the defensive asyncio introspection hardening out of #17624 into its own standalone PR. These guards are independent of Python 3.15 — they harden ddtrace/profiling/_asyncio.py against future CPython internal API changes (3.16+) and against runtime edge cases that also apply to 3.10–3.14.

Stack

Changes

  • ddtrace/profiling/_asyncio.py:
    • Guard hasattr access to every asyncio private API we introspect: _scheduled_tasks, _eager_tasks, _all_tasks, _GatheringFuture, _wait, task WeakSet internals. On known versions <3.16 a missing attribute raises with a GitHub issue link; on unknown versions >=3.16 we warn and degrade gracefully.
    • Wrap asyncio.get_running_loop / asyncio.current_task calls inside our task-link wrappers with try/except RuntimeError so a task completing outside of a running loop — observed on 3.15 — no longer propagates an exception into user code.
    • Introduce structural Protocol classes _HasSetEventLoop, _HasCreateTask and explicit type annotations for the attributes we introspect, so the contract we depend on is documented.
  • ddtrace/internal/wrapping/{asyncs,context,generators}.py:
    • Matching type-annotation polish on the wrapping helpers touched by the new guards.

Why split this out

Testing

Release notes

No user-facing behavior change beyond graceful handling of future-version attribute removals. Tagging changelog/no-changelog to match the rest of the 3.15 PR stack (#17531, #17624).

fix(profiling): guard asyncio private APIs against future removal
6e58750 
_GatheringFuture and _wait are asyncio internals with no stability contract.
Wrap each with hasattr so removal/rename in a future CPython release degrades
gracefully (task linking silently skipped) instead of AttributeError at
profiler startup.

Also adds AIDEV-TODO comments flagging the asyncio policy system deprecation
in 3.15 (CPython #127949, removal in 3.16) for the next CPython port.

a394f2d 
…asyncio internals

On Python <= 3.15 (validated versions), missing _GatheringFuture or _wait is a
real bug — raise RuntimeError immediately so it is never silently swallowed.
On Python >= 3.16 (where the asyncio policy system is being removed and these
internals may disappear), degrade gracefully with a log.warning so the profiler
still starts with reduced task-link coverage.

…emoval

Apply same tiered hasattr + RuntimeError/log.warning pattern to
_scheduled_tasks and _all_tasks in _call_init_asyncio(). On Python <=3.15
(validated versions) a missing attribute raises immediately; on Python >=3.16
it degrades gracefully with a warning. _eager_tasks uses getattr fallback
since it was added in 3.12 and absence is not an error.

Slimming down: the only commit needed for 3.15 robustness (current_task() RuntimeError guard) was folded into #17624. The other 5 commits in this PR are 3.16+ future-proofing (defensive guards for asyncio private API removal) and pure type annotations — deferred to a future stack. Closing without merge.
