gh-142476: fix memory leak when creating JIT executors by ashm-dev · Pull Request #142492 · python/cpython

ashm-dev · 2025-12-09T20:27:32Z

Issue: ASan memory leak in test_gc with --enable-experimental-jit (allocate_executor) #142476

ashm-dev · 2025-12-09T20:32:04Z

I believe a news entry is not required for this change.

Fidget-Spinner

Wow, great catch!

Could you please add a comment(review below) so that we know why this is needed?

Fidget-Spinner · 2025-12-09T23:59:27Z

The failing Windows test is likely because of https://github.com/python/cpython/pull/137016/files. Could you please try pulling in the changes from there?

ashm-dev · 2025-12-10T04:07:10Z

Yes, applying the changes from #137016 fixes the Windows crash.

Fidget-Spinner · 2025-12-10T09:52:58Z

We need this to be merged first https://github.com/python/cpython/pull/137016/files

Also, I'm not sure I get why we DECREF executor in _Py_ExecutorDetach? It is called from executor_clear with self and it doesn't seem right to me.

Maybe @markshannon can shed a light to this, because of #118459

Detach is for removing the executor from a code object. The code object owns a strong reference to the executor so we must decref it.

sergey-miryanov · 2025-12-12T20:10:14Z

@Fidget-Spinner Thanks!

ashm-dev · 2025-12-12T22:05:19Z

The crashes were caused by a double untrack exposed by the fix.

The original fix correctly drops the reference.
If the executor is destroyed during a GC cycle (via tp_clear), the GC has already untracked the object.
uop_dealloc was blindly calling _PyObject_GC_UNTRACK again, causing assertion failures (Windows) and heap corruption (Linux/Mac).

The fix: Guard the untrack call with if (_PyObject_GC_IS_TRACKED(self)).

ashm-dev · 2025-12-12T22:11:57Z

@Fidget-Spinner I've added the news entry.

Fidget-Spinner · 2025-12-13T14:33:29Z

So I'm gonna leave this around for a few more days. However could you please add a code comment above the if that tp_traverse might untrack the onject once it breaks cycles, so we need to not double-untrack it please?

ashm-dev · 2025-12-13T15:40:45Z

Got it, sounds good — I’ll do that.

sergey-miryanov · 2025-12-19T04:57:35Z

@ashm-dev #142931 changed the schema of the executors management. Could you please re-apply your changes and retest?

ashm-dev · 2025-12-19T08:03:47Z

@sergey-miryanov The project doesn't even build right now, so I'm unable to verify it. I'm building Python from the main branch as follows: CC=clang-21 CXX=clang++-21 ./configure --with-pydebug --with-address-sanitizer --enable-experimental-jit=yes && make -j, and here is the result (I'm attaching the logs and ASan leaks below):

@ashm-dev does the project build if you apply this patch here to main?

ashm-dev · 2025-12-19T09:17:22Z

@Fidget-Spinner No, it doesn't build even with my patch applied. It looks like the JIT is broken again.

Fidget-Spinner

It's not broken (apart from the refcount leak I think), the current patch seems to be breaking it.

ashm-dev · 2025-12-19T09:35:04Z

But it doesn't build on main either, even without my patch. I posted the logs above.

sergey-miryanov

Looks good to me. Thanks!

@ashm-dev I think you're misunderstanding me. I'm asking if it builds with this patch currently on this branch?

ashm-dev · 2025-12-19T10:27:24Z

@Fidget-Spinner Yes, it builds!
