* gh-115999: Add free-threaded specialization for FOR_ITER (#128798)T. Wouters2025-03-126-44/+311
| | | | Add free-threaded versions of existing specialization for FOR_ITER (list, tuples, fast range iterators and generators), without significantly affecting their thread-safety. (Iterating over shared lists/tuples/ranges should be fine like before. Reusing iterators between threads is not fine, like before. Sharing generators between threads is a recipe for significant crashes, like before.)

* gh-130920: Fix data race in STORE_SUBSCR_LIST_INT (#130923)Sam Gross2025-03-063-3/+6
| | | | | | The write of the item to the list needs to use an atomic operation in the free threading build. Co-authored-by: Tomasz Pytel <tompytel@gmail.com>
* gh-124878: Fix race conditions during interpreter finalization (#130649)Sam Gross2025-03-064-57/+79
| | | | | | | | | | | | | | | | | | | | The PyThreadState field gains a reference count field to avoid issues with PyThreadState being a dangling pointer to freed memory. The refcount starts with a value of two: one reference is owned by the interpreter's linked list of thread states and one reference is owned by the OS thread. The reference count is decremented when the thread state is removed from the interpreter's linked list and before the OS thread calls `PyThread_hang_thread()`. The thread that decrements it to zero frees the `PyThreadState` memory. The `holds_gil` field is moved out of the `_status` bit field, to avoid a data race where on thread calls `PyThreadState_Clear()`, modifying the `_status` bit field while the OS thread reads `holds_gil` when attempting to acquire the GIL. The `PyThreadState.state` field now has `_Py_THREAD_SHUTTING_DOWN` as a possible value. This corresponds to the `_PyThreadState_MustExit()` check. This avoids race conditions in the free threading build when checking `_PyThreadState_MustExit()`.
* gh-130860: Fix width calculation, when separators in fractional part (GH-130865)Sergey B Kirpichev2025-03-061-17/+18

* gh-130574: renumber RESUME opcode from 149 to 128 (GH-130685)Tomasz Pytel2025-03-061-42/+42

* gh-118331: Fix a couple of issues when list allocation fails (#130811)mpage2025-03-052-0/+4
| | | | | | | | | | | | | | | | * Fix use after free in list objects Set the items pointer in the list object to NULL after the items array is freed during list deallocation. Otherwise, we can end up with a list object added to the free list that contains a pointer to an already-freed items array. * Mark `_PyList_FromStackRefStealOnSuccess` as escaping I think technically it's not escaping, because the only object that can be decrefed if allocation fails is an exact list, which cannot execute arbitrary code when it is destroyed. However, this seems less intrusive than trying to special cases objects in the assert in `_Py_Dealloc` that checks for non-null stackpointers and shouldn't matter for performance.
