de4d183955 Issue #18327: Fix argument order in call to compatible_for_assignment(oldto, newto, attr). 
The fix only affects the error message of __class__ assignment. CID 983564

2c40f640d9 Issue #18408: Fix list_ass_slice(), handle list_resize() failure 
I tested the patch manually by injecting a fault using gdb: list items are
correctly restored on failure.

8e47832737 Issue #18408: PyObject_Str(), PyObject_Repr() and type_call() now fail with an 
assertion error if they are called with an exception set (PyErr_Occurred()).

As PyEval_EvalFrameEx(), they may clear the current exception and so the caller
looses its exception.

f97dfd7b59 Issue #18408: Fix dict_repr(), don't call PyObject_Repr() with an exception set 
PyObject_Repr() can removes the current exception. For example, module_repr()
calls PyErr_Clear() if calling loader.module_repr(mod) failed.

26f91999b4 Close #18469: Replace PyDict_GetItemString() with _PyDict_GetItemId() in structseq.c 
_PyDict_GetItemId() is more efficient: it only builds the Unicode string once.
Identifiers (dictionary keys) are now created at Python initialization, and if
the creation failed, Python does exit with a fatal error.

Before, PyDict_GetItemString() failure was not handled: structseq_new() could
call PyObject_GC_NewVar() with a negative size, and structseq_dealloc() could
also crash.

3997cfdb7f Cleanup type_call() to ease debug 
It was easy to miss the call to type->tp_init because it was done in a long
conditional expression. Split the long expression in multiple lines to make the
debug step by step easier.

e699e5a218 Issue #18408: Don't check unicode consistency in _PyUnicode_HAS_UTF8_MEMORY() 
and _PyUnicode_HAS_WSTR_MEMORY() macros

These macros are called in unicode_dealloc(), whereas the unicode object can be
"inconsistent" if the creation of the object failed.

For example, when unicode_subtype_new() fails on a memory allocation,
_PyUnicode_CheckConsistency() fails with an assertion error because data is
NULL.

9035ad932b Issue #18408: In debug mode, PyCFunction_Call() now checks if an exception was

2e8474ddde Issue #18408: slot_tp_str() must not fallback on slot_tp_repr() on error 
type->tp_str must not point to slot_tp_str() if type has no __str__ attribute,
so there is no reason for slot_tp_str() to fallback on slot_tp_str() on lookup
error. Moreover, calling PyErr_Clear() may hide a real bug like MemoryError.

If __str__ attribute is removed, slots must be updated (which is done by
type_setattro()).

c4266360fc Issue #18408: Fix _PyMem_DebugRealloc() 
Don't mark old extra memory dead before calling realloc(). realloc() can fail
and realloc() must not touch the original buffer on failure.

So mark old extra memory dead only on success if the new buffer did not move
(has the same address).

  of PyMem_Malloc()

0507bf56f0 Issue #3329: Implement the PEP 445 
Add new enum:

* PyMemAllocatorDomain

Add new structures:

* PyMemAllocator
* PyObjectArenaAllocator

Add new functions:

* PyMem_RawMalloc(), PyMem_RawRealloc(), PyMem_RawFree()
* PyMem_GetAllocator(), PyMem_SetAllocator()
* PyObject_GetArenaAllocator(), PyObject_SetArenaAllocator()
* PyMem_SetupDebugHooks()

Changes:

* PyMem_Malloc()/PyObject_Realloc() now always call malloc()/realloc(), instead
  of calling PyObject_Malloc()/PyObject_Realloc() in debug mode.
* PyObject_Malloc()/PyObject_Realloc() now falls back to
  PyMem_Malloc()/PyMem_Realloc() for allocations larger than 512 bytes.
* Redesign debug checks on memory block allocators as hooks, instead of using C
  macros
