* bpo-44263: Fix _decimal and _testcapi GC protocol (GH-26464) (GH-26465)Miss Islington (bot)2021-05-311-2/+1
| | | | | | | | | | | * _testcapi.heapgctype: implement a traverse function since the type is defined with Py_TPFLAGS_HAVE_GC. * _decimal: PyDecSignalDictMixin_Type is no longer defined with Py_TPFLAGS_HAVE_GC since it has no traverse function. (cherry picked from commit 142e5c5445c019542246d93fe2f9e195d3131686) Co-authored-by: Victor Stinner <vstinner@python.org> Co-authored-by: Victor Stinner <vstinner@python.org>

* bpo-43422: Revert _decimal C API addition (GH-24960)Antoine Pitrou2021-03-211-193/+7
| | | | | | | | | Stefan Krah requested the reversal of these (unreleased) changes, quoting him: > The capsule API does not meet my testing standards, since I've focused on the upstream mpdecimal in the last couple of months. > Additionally, I'd like to refine the API, perhaps together with the Arrow community.

* 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-42006: Stop using PyDict_GetItem, PyDict_GetItemString and ↵Serhiy Storchaka2020-10-261-17/+30
| | | | | | | | | | | _PyDict_GetItemId. (GH-22648) These functions are considered not safe because they suppress all internal errors and can return wrong result. PyDict_GetItemString and _PyDict_GetItemId can also silence current exception in rare cases. Remove no longer used _PyDict_GetItemId. Add _PyDict_ContainsId and rename _PyDict_Contains into _PyDict_Contains_KnownHash.

| | | | | library numeric types (GH-6121)" (GH-22584) This reverts commit 58a7da9e125422323f79c4ee95ac5549989d8162.
* bpo-26680: Incorporate is_integer in all built-in and standard library ↵Robert Smallshire2020-10-011-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-41302: Fix build with system libmpdec (GH-21481)Felix Yan2020-07-151-0/+5
| | | | | | | Move definition of UNUSED from modified headers of libmpdec to _decimal.c itself. This makes the vendored source closer to the standalone library and fixes build with --with-system-libmpdec. Tested to build fine with either system libmpdec or the vendored one.

* bpo-40268: Remove unused structmember.h includes (GH-19530)Victor Stinner2020-04-151-1/+0

* bpo-40268: Remove explicit pythread.h includes (#19529)Victor Stinner2020-04-151-1/+0

* bpo-36974: tp_print -> tp_vectorcall_offset and tp_reserved -> tp_as_async ↵Jeroen Demeyer2019-05-311-8/+8
