* 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-38200: Add itertools.pairwise() (GH-23549)Raymond Hettinger2020-12-011-1/+136
|
* 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.
* bpo-41078: Rename pycore_tupleobject.h to pycore_tuple.h (GH-21056)Victor Stinner2020-06-221-1/+1
|
* bpo-40898: Remove redundant if statements in tp_traverse (GH-20692)Hai Shi2020-06-071-2/+1
|
* bpo-40268: Remove unused structmember.h includes (GH-19530)Victor Stinner2020-04-151-1/+1
| | | | | | If only offsetof() is needed: include stddef.h instead. When structmember.h is used, add a comment explaining that PyMemberDef is used.

* bpo-15999: Clean up of handling boolean arguments. (GH-15610)Serhiy Storchaka2019-09-011-3/+3

* bpo-37976: Prevent shadowing of TypeError in zip() (GH-15592)Sergey Fedoseev2019-08-301-4/+0

* bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. ↵Siddhesh Poyarekar2018-04-291-23/+23
| | | | | | | | | (GH-6030) METH_NOARGS functions need only a single argument but they are cast into a PyCFunction, which takes two arguments. This triggers an invalid function cast warning in gcc8 due to the argument mismatch. Fix this by adding a dummy unused argument.

| | | | | (#3631) Affected classes are bytearray, array, deque, defaultdict, count and repeat.
* bpo-31497: Add private helper _PyType_Name(). (#3630)Serhiy Storchaka2017-09-171-4/+3
| | | | This function returns the last component of tp_name after a dot. Returns tp_name itself if it doesn't contain a dot.
