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.

Sam Gross	a025f27d94	gh-130920: Fix data race in STORE_SUBSCR_LIST_INT (#130923) ... 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>	2025-03-06 15:59:48 -05:00
Sam Gross	052cb717f5	gh-124878: Fix race conditions during interpreter finalization (#130649) ... 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()`.	2025-03-06 10:38:34 -05:00
Sergey B Kirpichev	2352bd418a	gh-130860: Fix width calculation, when separators in fractional part (GH-130865) ... This amends f39a07be47	2025-03-06 14:26:29 +02:00

mpage	d7bb7c7817	gh-118331: Fix a couple of issues when list allocation fails (#130811) ... * 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.	2025-03-05 10:42:09 -08:00
Mark Shannon	78d50e91ff	GH-127705: better double free message. (GH-130785) ... * Add location information when accessing already closed stackref * Add #def option to track closed stackrefs to provide precise information for use after free and double frees.	2025-03-05 14:00:42 +00:00
Sam Gross	2f6e0e9f70	gh-130794: Process interpreter QSBR queue in _PyMem_AbandonDelayed. (gh-130808) ... This avoids a case where the interpreter's queue of memory to be freed could grow rapidly if there are many short lived threads.	2025-03-04 18:04:04 -05:00

Hugo Beauzée-Luyssen	214562ed4d	gh-130740: Move some `stdbool.h` includes after `Python.h` (#130738) ... Move some `#include <stdbool.h>` after `#include "Python.h"` when `pyconfig.h` is not included first and when we are in a platform-agnostic context. This is to avoid having features defined by `stdbool.h` before those decided by `Python.h`.	2025-03-02 09:56:49 +00:00

Sam Gross	7aeaa5af2c	gh-130091: Reorder `_PyThreadState_Attach` to avoid data race (gh-130092) ... This moves `tstate_activate()` down to avoid a data race in the free threading build on the `_PyRuntime`'s thread-local `autoTSSkey`. This key is deleted during runtime finalization, which may happen concurrently with a call to `_PyThreadState_Attach`. The earlier `tstate_try/wait_attach` ensures that the thread is blocked before it attempts to access the deleted `autoTSSkey`. This fixes a TSAN reported data race in `test_threading.test_import_from_another_thread`.	2025-02-27 13:57:19 -05:00

Sam Gross	ca22147547	gh-111924: Fix data races when swapping allocators (gh-130287) ... CPython current temporarily changes `PYMEM_DOMAIN_RAW` to the default allocator during initialization and shutdown. The motivation is to ensure that core runtime structures are allocated and freed using the same allocator. However, modifying the current allocator changes global state and is not thread-safe even with the GIL. Other threads may be allocating or freeing objects use PYMEM_DOMAIN_RAW; they are not required to hold the GIL to call PyMem_RawMalloc/PyMem_RawFree. This adds new internal-only functions like `_PyMem_DefaultRawMalloc` that aren't affected by calls to `PyMem_SetAllocator()`, so they're appropriate for Python runtime initialization and finalization. Use these calls in places where we previously swapped to the default raw allocator.	2025-02-20 11:31:15 -05:00

mpage	13c4def692	gh-128955: Fix goto if tlbc creation fails when throwing into a generator (#128957) ... We don't have the correct copy of the bytecode and can't update next_instr appropriately, so just unwind.	2025-01-17 12:53:29 -08:00
Sam Gross	d66c08aa75	gh-128923: Use zero to indicate unassigned unique id (#128925) ... In the free threading build, the per thread reference counting uses a unique id for some objects to index into the local reference count table. Use 0 instead of -1 to indicate that the id is not assigned. This avoids bugs where zero-initialized heap type objects look like they have a unique id assigned.	2025-01-17 16:42:27 +01:00

Anders Kaseorg	a626f9a67b	Remove asserts that confuse `enum _framestate` with `enum _frameowner` (GH-124148) ... The `owner` field of `_PyInterpreterFrame` is supposed to be a member of `enum _frameowner`, but `FRAME_CLEARED` is a member of `enum _framestate`. At present, it happens that `FRAME_CLEARED` is not numerically equal to any member of `enum _frameowner`, but that could change in the future. The code that incorrectly assigned `owner = FRAME_CLEARED` was deleted in commit a53cc3f494 (GH-116687). Remove the incorrect checks for `owner != FRAME_CLEARED` as well.	2025-01-02 16:55:33 +00:00
