* bpo-41342: Convert int.__round__ to Argument Clinic (GH-21549)Serhiy Storchaka2020-07-201-7/+15

* bpo-41123: Remove PyLong_FromUnicode() (GH-21204)Inada Naoki2020-06-291-11/+0

* 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 Remove an outdated comment on _Py_tracemalloc_config.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-37986: Improve perfomance of PyLong_FromDouble() * Use strict bound check for safety and symmetry * Remove possibly outdated performance claims Co-authored-by: Mark Dickinson <dickinsm@gmail.com>
* bpo-40455: Remove gcc10 warning about x_digits (#19852)Dong-hee Na2020-05-041-4/+3
| | | | | | | * bpo-40455: Remove gcc10 warning about x_digits * bpo-40455: nit * bpo-40455: fix logic error
* 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.

| | | | (GH-19472)

* bpo-39573: Use Py_SET_SIZE() function (GH-18402)Victor Stinner2020-02-071-31/+37
| | | | Replace direct acccess to PyVarObject.ob_size with usage of the Py_SET_SIZE() function.
* bpo-39573: Use Py_TYPE() macro in Objects directory (GH-18392)Victor Stinner2020-02-071-4/+4
| | | Replace direct access to PyObject.ob_type with Py_TYPE().
* bpo-39489: Remove COUNT_ALLOCS special build (GH-18259)Victor Stinner2020-02-031-10/+0

* 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
| | | | | standard macros (GH-15385) Use standard constants LLONG_MIN, LLONG_MAX and ULLONG_MAX.

|
* Make PyXXX_Fini() functions private (GH-15531)Victor Stinner2019-08-261-1/+1

| | | | Classes that define __str__ the same as __repr__ can just inherit it from object.
* bpo-36292: Mark unreachable code as such in long bitwise ops (GH-12333)stratakis2019-03-181-4/+2

* bpo-36048: Use __index__() instead of __int__() for implicit conversion if ↵Serhiy Storchaka2019-02-251-9/+76

| | | | | | PyObject_INIT() and PyObject_INIT_VAR() now cast their first argument to PyObject*, as done in Python 3.7. Revert partially commit b4435e20a92af474f117b78b98ddc6f515363af5.
* bpo-35064 prefix smelly symbols that appear with COUNT_ALLOCS with _Py_ ↵Pablo Galindo2018-10-281-3/+3
| | | | | | | (GH-10152) Configuring python with ./configure --with-pydebug CFLAGS="-D COUNT_ALLOCS -O0" makes "make smelly" fail as some symbols were being exported without the "Py_" or "_Py" prefixes.
* bpo-35059: Convert PyObject_INIT() to function (GH-10077)Victor Stinner2018-10-261-2/+2
| | | | | * Convert PyObject_INIT() and PyObject_INIT_VAR() macros to static inline functions. * Fix usage of these functions: cast to PyObject* or PyVarObject*.
