* gh-132639: Adds PyLong_AsNativeBytes, PyLong_FromNativeBytes and ↵Steve Dower2025-04-211-51/+0

* gh-111178: Fix function signatures in longobject.c (#124895)Victor Stinner2024-10-021-0/+3
| | | | | | | | | | | | | | * Add _PyLong_CAST() macro. * Move forward declarations to the top of longobject.c. * Change long_add(), long_sub(), long_mul(), long_neg(), long_lshift(), long_abs() to take PyLongObject* and return PyLongObject*. Avoid CHECK_BINOP() test. * Add long_add_method(), long_sub_method(), long_mul_method(), long_neg_method(), long_lshift_method(), and long_abs_method() which take PyObject* and return PyObject*. Implement CHECK_BINOP() test. * Add long_lshift_int64() function. * _PyLong_DivmodNear() calls long_lshift_int64(obj, 1) instead of long_lshift_obj(obj, one).
* gh-123497: New limit for Python integers on 64-bit platforms (GH-123724)Serhiy Storchaka2024-09-291-3/+2
| | | | | | | | | | | Instead of be limited just by the size of addressable memory (2**63 bytes), Python integers are now also limited by the number of bits, so the number of bit now always fit in a 64-bit integer. Both limits are much larger than what might be available in practice, so it doesn't affect users. _PyLong_NumBits() and _PyLong_Frexp() are now always successful.
* gh-121485: Always use 64-bit integers for integers bits count (GH-121486)Serhiy Storchaka2024-08-301-2/+2
| | | | | Use 64-bit integers instead of platform specific size_t or Py_ssize_t to represent the number of bits in Python integer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Restore removed private C API functions, macros and structures which have no simple replacement for now: * _PyDict_GetItem_KnownHash() * _PyDict_NewPresized() * _PyHASH_BITS * _PyHASH_IMAG * _PyHASH_INF * _PyHASH_MODULUS * _PyHASH_MULTIPLIER * _PyLong_Copy() * _PyLong_FromDigits() * _PyLong_New() * _PyLong_Sign() * _PyObject_CallMethodId() * _PyObject_CallMethodNoArgs() * _PyObject_CallMethodOneArg() * _PyObject_CallOneArg() * _PyObject_EXTRA_INIT * _PyObject_FastCallDict() * _PyObject_GetAttrId() * _PyObject_Vectorcall() * _PyObject_VectorcallMethod() * _PyStack_AsDict() * _PyThread_CurrentFrames() * _PyUnicodeWriter structure * _PyUnicodeWriter_Dealloc() * _PyUnicodeWriter_Finish() * _PyUnicodeWriter_Init() * _PyUnicodeWriter_Prepare() * _PyUnicodeWriter_PrepareKind() * _PyUnicodeWriter_WriteASCIIString() * _PyUnicodeWriter_WriteChar() * _PyUnicodeWriter_WriteLatin1String() * _PyUnicodeWriter_WriteStr() * _PyUnicodeWriter_WriteSubstring() * _PyUnicode_AsString() * _PyUnicode_FromId() * _PyVectorcall_Function() * _Py_HashDouble() * _Py_HashPointer() * _Py_IDENTIFIER() * _Py_c_abs() * _Py_c_diff() * _Py_c_neg() * _Py_c_pow() * _Py_c_prod() * _Py_c_quot() * _Py_c_sum() * _Py_static_string() * _Py_static_string_init()
* gh-106320: Re-add some PyLong/PyDict C-API functions (GH-#111162)scoder2023-10-251-0/+42
| | | | | | | | * gh-106320: Re-add _PyLong_FromByteArray(), _PyLong_AsByteArray() and _PyLong_GCD() to the public header files since they are used by third-party packages and there is no efficient replacement. See https://github.com/python/cpython/issues/111140 See https://github.com/python/cpython/issues/111139 * gh-111262: Re-add _PyDict_Pop() to have a C-API until a new public one is designed.
* gh-106320: Remove private _PyLong_Sign() (#108743)Victor Stinner2023-09-011-15/+0
| | | | | | Move the private _PyLong_Sign() and _PyLong_NumBits() functions to the internal C API (pycore_long.h). Modules/_testcapi/long.c now uses the internal C API.
* gh-106320: Remove private _PyLong_FileDescriptor_Converter() (#108503)Victor Stinner2023-08-261-2/+0
| | | | | | | | | Move the private _PyLong converter functions to the internal C API * _PyLong_FileDescriptor_Converter(): moved to pycore_fileutils.h * _PyLong_Size_t_Converter(): moved to pycore_long.h Argument Clinic now emits includes for pycore_fileutils.h and pycore_long.h when these functions are used.
* gh-106320: Remove private _PyLong converter functions (#108499)Victor Stinner2023-08-261-4/+0
| | | | | | | | | | | Move these private functions to the internal C API (pycore_long.h): * _PyLong_UnsignedInt_Converter() * _PyLong_UnsignedLongLong_Converter() * _PyLong_UnsignedLong_Converter() * _PyLong_UnsignedShort_Converter() Argument Clinic now emits #include "pycore_long.h" when these functions are used.
* gh-108444: Remove _PyLong_AsInt() function (#108461)Victor Stinner2023-08-251-3/+0
| | | | * Update Parser/asdl_c.py to regenerate Python/Python-ast.c. * Remove _PyLong_AsInt() alias to PyLong_AsInt().
* gh-108444: Add PyLong_AsInt() public function (#108445)Victor Stinner2023-08-241-1/+2
| | | | | | * Rename _PyLong_AsInt() to PyLong_AsInt(). * Add documentation. * Add test. * For now, keep _PyLong_AsInt() as an alias to PyLong_AsInt().
* gh-106320: Remove private PyLong C API functions (#108429)Victor Stinner2023-08-241-69/+1
