* bpo-43687: Py_Initialize() creates singletons earlier (GH-25147)Victor Stinner2021-04-021-8/+11
| | | | | Reorganize pycore_interp_init() to initialize singletons before the the first PyType_Ready() call. Fix an issue when Python is configured using --without-doc-strings.
* bpo-42128: Structural Pattern Matching (PEP 634) (GH-22917)Brandt Bucher2021-02-261-1/+2
| | | | | Co-authored-by: Guido van Rossum <guido@python.org> Co-authored-by: Talin <viridia@gmail.com> Co-authored-by: Pablo Galindo <pablogsal@gmail.com>
* bpo-43268: Pass interp rather than tstate to internal functions (GH-24580)Victor Stinner2021-02-191-5/+5
| | | | | | | | | | | | | | | Pass the current interpreter (interp) rather than the current Python thread state (tstate) to internal functions which only use the interpreter. Modified functions: * _PyXXX_Fini() and _PyXXX_ClearFreeList() functions * _PyEval_SignalAsyncExc(), make_pending_calls() * _PySys_GetObject(), sys_set_object(), sys_set_object_id(), sys_set_object_str() * should_audit(), set_flags_from_config(), make_flags() * _PyAtExit_Call() * init_stdio_encoding() * etc.
* bpo-43268: _Py_IsMainInterpreter() now expects interp (GH-24577)Victor Stinner2021-02-191-1/+1
| | | | The _Py_IsMainInterpreter() function now expects interp rather than tstate.
* bpo-42519: Replace PyObject_MALLOC() with PyObject_Malloc() (GH-23587)Victor Stinner2020-12-011-1/+1
| | | | | | | | | No longer use deprecated aliases to functions: * Replace PyObject_MALLOC() with PyObject_Malloc() * Replace PyObject_REALLOC() with PyObject_Realloc() * Replace PyObject_FREE() with PyObject_Free() * Replace PyObject_Del() with PyObject_Free() * Replace PyObject_DEL() with PyObject_Free()
* bpo-42161: Remove private _PyLong_Zero and _PyLong_One (GH-23003)Victor Stinner2020-10-271-18/+0
| | | | | Use PyLong_FromLong(0) and PyLong_FromLong(1) of the public C API instead. For Python internals, _PyLong_GetZero() and _PyLong_GetOne() of pycore_long.h can be used.
* bpo-42161: Add _PyLong_GetZero() and _PyLong_GetOne() (GH-22993)Victor Stinner2020-10-261-23/+14
| | | | | | Add _PyLong_GetZero() and _PyLong_GetOne() functions and a new internal pycore_long.h header file. Python cannot be built without small integer singletons anymore.
* Revert "bpo-26680: Incorporate is_integer in all built-in and standard ↵Raymond Hettinger2020-10-071-14/+0
| | | | | library numeric types (GH-6121)" (GH-22584) This reverts commit 58a7da9e125422323f79c4ee95ac5549989d8162.
* bpo-26680: Incorporate is_integer in all built-in and standard library ↵Robert Smallshire2020-10-011-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | numeric types (GH-6121) * bpo-26680: Adds support for int.is_integer() for compatibility with float.is_integer(). The int.is_integer() method always returns True. * bpo-26680: Adds a test to ensure that False.is_integer() and True.is_integer() are always True. * bpo-26680: Adds Real.is_integer() with a trivial implementation using conversion to int. This default implementation is intended to reduce the workload for subclass implementers. It is not robust in the presence of infinities or NaNs and may have suboptimal performance for other types. * bpo-26680: Adds Rational.is_integer which returns True if the denominator is one. This implementation assumes the Rational is represented in it's lowest form, as required by the class docstring. * bpo-26680: Adds Integral.is_integer which always returns True. * bpo-26680: Adds tests for Fraction.is_integer called as an instance method. The tests for the Rational abstract base class use an unbound method to sidestep the inability to directly instantiate Rational. These tests check that everything works correct as an instance method. * bpo-26680: Updates documentation for Real.is_integer and built-ins int and float. The call x.is_integer() is now listed in the table of operations which apply to all numeric types except complex, with a reference to the full documentation for Real.is_integer(). Mention of is_integer() has been removed from the section 'Additional Methods on Float'. The documentation for Real.is_integer() describes its purpose, and mentions that it should be overridden for performance reasons, or to handle special values like NaN. * bpo-26680: Adds Decimal.is_integer to the Python and C implementations. The C implementation of Decimal already implements and uses mpd_isinteger internally, we just expose the existing function to Python. The Python implementation uses internal conversion to integer using to_integral_value(). In both cases, the corresponding context methods are also implemented. Tests and documentation are included. * bpo-26680: Updates the ACKS file. * bpo-26680: NEWS entries for int, the numeric ABCs and Decimal. Co-authored-by: Robert Smallshire <rob@sixty-north.com>

* bpo-40989: PyObject_INIT() becomes an alias to PyObject_Init() (GH-20901)Victor Stinner2020-06-151-1/+3
| | | | | | | | | | | | | | The PyObject_INIT() and PyObject_INIT_VAR() macros become aliases to, respectively, PyObject_Init() and PyObject_InitVar() functions. Rename _PyObject_INIT() and _PyObject_INIT_VAR() static inline functions to, respectively, _PyObject_Init() and _PyObject_InitVar(), and move them to pycore_object.h. Remove their return value: their return type becomes void. The _datetime module is now built with the Py_BUILD_CORE_MODULE macro defined. Remove an outdated comment on _Py_tracemalloc_config.
* bpo-29782: Consolidate _Py_Bit_Length() (GH-20739)Niklas Fiekas2020-06-151-9/+16
| | | | | | | | | | In GH-2866, _Py_Bit_Length() was added to pymath.h for lack of a better location. GH-20518 added a more appropriate header file for bit utilities. It also shows how to properly use intrinsics. This allows reconsidering bpo-29782. * Move the function to the new header. * Changed return type to match __builtin_clzl() and reviewed usage. * Use intrinsics where available. * Pick a fallback implementation suitable for inlining.
* bpo-39465: Use _PyInterpreterState_GET() (GH-20788)Victor Stinner2020-06-101-2/+2
| | | | | | | | | | | | Replace _PyThreadState_GET() with _PyInterpreterState_GET() in: * get_small_int() * gcmodule.c: add also get_gc_state() function * _PyTrash_deposit_object() * _PyTrash_destroy_chain() * warnings_get_state() * Py_GetRecursionLimit() Cleanup listnode.c: add 'parser' variable.
* bpo-29882: Add _Py_popcount32() function (GH-20518)Victor Stinner2020-06-081-8/+7
| | | | | | * Rename pycore_byteswap.h to pycore_bitutils.h. * Move popcount_digit() to pycore_bitutils.h as _Py_popcount32(). * _Py_popcount32() uses GCC and clang builtin function if available. * Add unit tests to _Py_popcount32().
* bpo-29882: Add an efficient popcount method for integers (#771)Niklas Fiekas2020-05-291-0/+70
| | | | | | | | | | | | | | | | | | | | | | | * bpo-29882: Add an efficient popcount method for integers * Update 'sign bit' and versionadded in docs * Add entry to whatsnew document * Doc: use positive example, mention population count * Minor cleanups of the core code * Move popcount_digit closer to where it's used * Use z instead of self after conversion * Add 'absolute value' and 'population count' to docstring * Fix clinic error about missing summary line * Ensure popcount_digit is portable with 64-bit ints Co-authored-by: Mark Dickinson <dickinsm@gmail.com>
* bpo-40792: Make the result of PyNumber_Index() always having exact type int. ↵Serhiy Storchaka2020-05-281-6/+6
| | | | | | | | | | | | (GH-20443) Previously, the result could have been an instance of a subclass of int. Also revert bpo-26202 and make attributes start, stop and step of the range object having exact type int. Add private function _PyNumber_Index() which preserves the old behavior of PyNumber_Index() for performance to use it in the conversion functions like PyLong_AsLong().
* bpo-37999: Fix outdated __int__ and nb_int references in comments (GH-20449)Mark Dickinson2020-05-271-8/+8
| | | | | | | | | * Fix outdated __int__ and nb_int references in comments * Also update C-API documentation * Add back missing 'method' word * Remove .. deprecated notices
* bpo-37999: No longer use __int__ in implicit integer conversions. (GH-15636)Serhiy Storchaka2020-05-261-122/+5
| | | | Only __index__ should be used to make integer conversions lossless.
* bpo-37986: Improve perfomance of PyLong_FromDouble() (GH-15611)Sergey Fedoseev2020-05-101-2/+16

* bpo-40268: Include explicitly pycore_interp.h (GH-19505)Victor Stinner2020-04-141-1/+2
| | | | pycore_pystate.h no longer includes pycore_interp.h: it's now included explicitly in files accessing PyInterpreterState.
* bpo-39943: Add the const qualifier to pointers on non-mutable PyBytes data. ↵Serhiy Storchaka2020-04-121-1/+1

* bpo-31031: Unify duplicate bits_in_digit and bit_length (GH-2866)Niklas Fiekas2020-01-161-29/+9
| | | Add _Py_bit_length() to unify duplicate bits_in_digit() and bit_length().
* bpo-38858: Small integer per interpreter (GH-17315)Victor Stinner2019-12-171-31/+28
| | | | | | | | | | | | Each Python subinterpreter now has its own "small integer singletons": numbers in [-5; 257] range. It is no longer possible to change the number of small integers at build time by overriding NSMALLNEGINTS and NSMALLPOSINTS macros: macros should now be modified manually in pycore_pystate.h header file. For now, continue to share _PyLong_Zero and _PyLong_One singletons between all subinterpreters.
* bpo-27961: Replace PY_LLONG_MAX, PY_LLONG_MIN and PY_ULLONG_MAX with ↵Sergey Fedoseev2019-12-051-5/+5
