* [3.11] gh-60203: Revert changes in cycle.__setstate__ (GH-99982) (#100016)Łukasz Langa2022-12-051-0/+1
| | | | | | | In case if only True/False be supported as boolean arguments in future, we should continue to support 1/0 here. (cherry picked from commit 922a6cf6c265e2763a003291885ff74d46203fc3) Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>
* bpo-46728: fix docstring of combinations_with_replacement for consistency ↵DongGeon Lee2022-02-151-2/+2

* bpo-46541: Replace core use of _Py_IDENTIFIER() with statically initialized ↵Eric Snow2022-02-081-10/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | global objects. (gh-30928) We're no longer using _Py_IDENTIFIER() (or _Py_static_string()) in any core CPython code. It is still used in a number of non-builtin stdlib modules. The replacement is: PyUnicodeObject (not pointer) fields under _PyRuntimeState, statically initialized as part of _PyRuntime. A new _Py_GET_GLOBAL_IDENTIFIER() macro facilitates lookup of the fields (along with _Py_GET_GLOBAL_STRING() for non-identifier strings). https://bugs.python.org/issue46541#msg411799 explains the rationale for this change. The core of the change is in: * (new) Include/internal/pycore_global_strings.h - the declarations for the global strings, along with the macros * Include/internal/pycore_runtime_init.h - added the static initializers for the global strings * Include/internal/pycore_global_objects.h - where the struct in pycore_global_strings.h is hooked into _PyRuntimeState * Tools/scripts/generate_global_objects.py - added generation of the global string declarations and static initializers I've also added a --check flag to generate_global_objects.py (along with make check-global-objects) to check for unused global strings. That check is added to the PR CI config. The remainder of this change updates the core code to use _Py_GET_GLOBAL_IDENTIFIER() instead of _Py_IDENTIFIER() and the related _Py*Id functions (likewise for _Py_GET_GLOBAL_STRING() instead of _Py_static_string()). This includes adding a few functions where there wasn't already an alternative to _Py*Id(), replacing the _Py_Identifier * parameter with PyObject *. The following are not changed (yet): * stop using _Py_IDENTIFIER() in the stdlib modules * (maybe) get rid of _Py_IDENTIFIER(), etc. entirely -- this may not be doable as at least one package on PyPI using this (private) API * (maybe) intern the strings during runtime init https://bugs.python.org/issue46541
* bpo-45439: Move _PyObject_CallNoArgs() to pycore_call.h (GH-28895)Victor Stinner2021-10-121-2/+1
| | | | | | | * Move _PyObject_CallNoArgs() to pycore_call.h (internal C API). * _ssl, _sqlite and _testcapi extensions now call the public PyObject_CallNoArgs() function, rather than _PyObject_CallNoArgs(). * _lsprof extension is now built with Py_BUILD_CORE_MODULE macro defined to get access to internal _PyObject_CallNoArgs().
* bpo-45439: Rename _PyObject_CallNoArg() to _PyObject_CallNoArgs() (GH-28891)Victor Stinner2021-10-111-1/+1
| | | | | Fix typo in the private _PyObject_CallNoArg() function name: rename it to _PyObject_CallNoArgs() to be consistent with the public function PyObject_CallNoArgs().
* Clean up initialization __class_getitem__ with Py_GenericAlias. (GH-28450)Serhiy Storchaka2021-09-191-1/+1
| | | | | 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 Storchaka2021-09-121-2/+4
| | | | | | | | 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-44563: Fix error handling in tee.fromiterable() (GH-27020)Serhiy Storchaka2021-07-051-9/+10
| | | In debug build failed tee.fromiterable() corrupted the linked list of all GC objects.
* bpo-42536: GC track recycled tuples (GH-23623)Brandt Bucher2020-12-051-0/+26
| | | | | | | | | | | | | | | | Several built-in and standard library types now ensure that their internal result tuples are always tracked by the garbage collector: - collections.OrderedDict.items - dict.items - enumerate - functools.reduce - itertools.combinations - itertools.combinations_with_replacement - itertools.permutations - itertools.product - itertools.zip_longest - zip Previously, they could have become untracked by a prior garbage collection.

* bpo-42161: Modules/ uses _PyLong_GetZero() and _PyLong_GetOne() (GH-22998)Victor Stinner2020-10-271-3/+5
| | | | | | Use _PyLong_GetZero() and _PyLong_GetOne() in Modules/ directory. _cursesmodule.c and zoneinfo.c are now built with Py_BUILD_CORE_MODULE macro defined.

| | | | | | | | | (GH-6030) METH_NOARGS functions need only a single argument but they are cast into a PyCFunction, which takes two arguments. This triggers an invalid function cast warning in gcc8 due to the argument mismatch. Fix this by adding a dummy unused argument.
