* bpo-45061: Detect refcount bug on empty string singleton (GH-28504)Victor Stinner2021-09-211-18/+37
| | | | | | | Detect refcount bugs in C extensions when the empty Unicode string singleton is destroyed by mistake. * Move forward declarations to the top of unicodeobject.c. * Simplifiy unicode_is_singleton().
* bpo-45061: Detect refcount bug on empty tuple singleton (GH-28503)Victor Stinner2021-09-213-5/+21
| | | | | | Detect refcount bugs in C extensions when the empty tuple singleton is destroyed by mistake. Add the _Py_FatalRefcountErrorFunc() function.
* Clean up initialization __class_getitem__ with Py_GenericAlias. (GH-28450)Serhiy Storchaka2021-09-198-9/+9
| | | | | The cast to PyCFunction is redundant. Overuse of redundant casts can hide actual bugs.

* bpo-43413: Fix handling keyword arguments in subclasses of some buitin ↵Serhiy Storchaka2021-09-126-12/+21
| | | | | | | | classes (GH-26456) * Constructors of subclasses of some buitin classes (e.g. tuple, list, frozenset) no longer accept arbitrary keyword arguments. * Subclass of set can now define a __new__() method with additional keyword parameters without overriding also __init__().
* bpo-44348: BaseException deallocator uses trashcan (GH-28190)Victor Stinner2021-09-071-1/+6
| | | | | | | | | | The deallocator function of the BaseException type now uses the trashcan mecanism to prevent stack overflow. For example, when a RecursionError instance is raised, it can be linked to another RecursionError through the __context__ attribute or the __traceback__ attribute, and then a chain of exceptions is created. When the chain is destroyed, nested deallocator function calls can crash with a stack overflow if the chain is too long compared to the available stack memory.
* bpo-45123: PyAiter_Check and PyObject_GetAiter fix & rename. (GH-28194)Yury Selivanov2021-09-071-7/+5
| | | | | | | | Fix PyAiter_Check to only check for the `__anext__` presense (not for `__aiter__`). Rename `PyAiter_Check()` to `PyAIter_Check()`, `PyObject_GetAiter()` -> `PyObject_GetAIter()`. Co-authored-by: Pablo Galindo Salgado <Pablogsal@gmail.com>

* bpo-34561: Switch to Munro & Wild "powersort" merge strategy. (#28108)Tim Peters2021-09-062-92/+177
| | | | | For list.sort(), replace our ad hoc merge ordering strategy with the principled, elegant, and provably near-optimal one from Munro and Wild's "powersort".
* bpo-45030: Fix integer overflow in __reduce__ of the range iterator (GH-28000)Serhiy Storchaka2021-09-041-16/+18
| | | | It happened with fast range iterator when the calculated stop = start + step * len was out of the C long range.
* bpo-45061: Detect Py_DECREF(Py_True) bug (GH-28089)Victor Stinner2021-08-312-7/+11
| | | | | Add a deallocator to the bool type to detect refcount bugs in C extensions which call Py_DECREF(Py_True) or Py_DECREF(Py_False) by mistake.

* bpo-44990: Change layout of evaluation frames. "Layout B" (GH-27933)Mark Shannon2021-08-253-25/+11
| | | Places the locals between the specials and stack. This is the more "natural" layout for a C struct, makes the code simpler and gives a slight speedup (~1%)

* Fix a SystemError in code.replace() (#27771)Guido van Rossum2021-08-161-3/+5
| | | | | | | While the comment said 'We don't bother resizing localspluskinds', this would cause .replace() to crash when it happened. (Also types.CodeType(), but testing that is tedious, and this tests all code paths.)
* bpo-44914: Maintain invariants of type version tags. (GH-27773)Mark Shannon2021-08-161-27/+13

| | | | | | | | | | | | | | | | | (GH-27530) * Unify the C and Python implementations of OrderedDict.popitem(). The C implementation no longer calls ``__getitem__`` and ``__delitem__`` methods of the OrderedDict subclasses. * Change popitem() and pop() methods of collections.OrderedDict For consistency with dict both implementations (pure Python and C) of these methods in OrderedDict no longer call __getitem__ and __delitem__ methods of the OrderedDict subclasses. Previously only the Python implementation of popitem() did not call them.
