* gh-99113: Add Py_MOD_PER_INTERPRETER_GIL_SUPPORTED (gh-104205)Eric Snow2023-05-051-0/+1
| | | Here we are doing no more than adding the value for Py_mod_multiple_interpreters and using it for stdlib modules. We will start checking for it in gh-104206 (once PyInterpreterState.ceval.own_gil is added in gh-104204).
* gh-101476: Add _PyType_GetModuleState (GH-101477)Erlend E. Aasland2023-02-231-1/+2
| | | For fast module state access from heap type methods.

* gh-60203: Revert changes in cycle.__setstate__ (#99982)Serhiy Storchaka2022-12-051-2/+3
| | | | In case if only True/False be supported as boolean arguments in future, we should continue to support 1/0 here.
* bpo-15999: Accept arbitrary values for boolean parameters. (#15609)Serhiy Storchaka2022-12-031-2/+2
| | | builtins and extension module functions and methods that expect boolean values for parameters now accept any Python object rather than just a bool or int type. This is more consistent with how native Python code itself behaves.
* gh-99845: Use size_t type in __sizeof__() methods (#99846)Victor Stinner2022-11-301-21/+13
| | | | | | | | The implementation of __sizeof__() methods using _PyObject_SIZE() now use an unsigned type (size_t) to compute the size, rather than a signed type (Py_ssize_t). Cast explicitly signed (Py_ssize_t) values to unsigned type (Py_ssize_t).
* gh-99537: Use Py_SETREF() function in C code (#99656)Victor Stinner2022-11-221-2/+1
| | | | | | | | | | | | | | | Fix potential race condition in code patterns: * Replace "Py_DECREF(var); var = new;" with "Py_SETREF(var, new);" * Replace "Py_XDECREF(var); var = new;" with "Py_XSETREF(var, new);" * Replace "Py_CLEAR(var); var = new;" with "Py_XSETREF(var, new);" Other changes: * Replace "old = var; var = new; Py_DECREF(var)" with "Py_SETREF(var, new);" * Replace "old = var; var = new; Py_XDECREF(var)" with "Py_XSETREF(var, new);" * And remove the "old" variable.
* gh-99300: Use Py_NewRef() in Modules/itertoolsmodule.c (#99439)Victor Stinner2022-11-131-62/+31

* bpo-46728: fix docstring of combinations_with_replacement for consistency ↵DongGeon Lee2022-02-151-2/+2
| | | | (GH-31293)
* 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.

| | | | | | If only offsetof() is needed: include stddef.h instead. When structmember.h is used, add a comment explaining that PyMemberDef is used.
