* bpo-35444: Unify and optimize the helper for getting a builtin object. ↵Serhiy Storchaka2018-12-111-1/+2
| | | | | | | | (GH-11047) This speeds up pickling of some iterators. This fixes also error handling in pickling methods when fail to look up builtin "getattr".
* bpo-34659: Adds initial kwarg to itertools.accumulate() (GH-9345)Lisa Roach2018-09-241-3/+29

* 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.
* bpo-32747: Remove trailing spaces in docstrings. (GH-5491)oldk2018-02-021-5/+5
|
* bpo-32571: Avoid raising unneeded AttributeError and silencing it in C code ↵Serhiy Storchaka2018-01-251-6/+4
| | | | | (GH-5222) Add two new private APIs: _PyObject_LookupAttr() and _PyObject_LookupAttrId()

* bpo-30346: An iterator produced by the itertools.groupby() iterator (#1569)Serhiy Storchaka2017-09-241-0/+8
| | | now becames exhausted after advancing the groupby iterator.
* bpo-27541: Reprs of subclasses of some classes now contain actual type name. ↵Serhiy Storchaka2017-09-211-6/+13
| | | | | (#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.
* bpo-30592: Fixed error messages for some builtins. (#1996)Serhiy Storchaka2017-06-081-7/+7
| | | | | Error messages when pass keyword arguments to some builtins that don't support keyword arguments contained double parenthesis: "()()". The regression was introduced by bpo-30534.
* bpo-30537: use PyNumber in itertools.islice instead of PyLong (#1918)Will Roberts2017-06-081-4/+4
| | | | | | | | * bpo-30537: use PyNumber in itertools instead of PyLong * bpo-30537: revert changes except to islice_new * bpo-30537: test itertools.islice and add entry to Misc/NEWS
* bpo-30061: Check if PyObject_Size()/PySequence_Size()/PyMapping_Size() (#1096)Serhiy Storchaka2017-04-191-1/+2
| | | | | | raised an error. Replace them with using concrete types API that never fails if appropriate.
* bpo-29942: Fix the use of recursion in itertools.chain.from_iterable. (#889)T. Wouters2017-03-301-24/+28
| | | | | Fix the use of recursion in itertools.chain.from_iterable. Using recursion is unnecessary, and can easily cause stack overflows, especially when building in low optimization modes or with Py_DEBUG enabled.
* bpo-29878: Add global instances of int for 0 and 1. (#852)Serhiy Storchaka2017-03-301-13/+5
|
* bpo-29865: Use PyXXX_GET_SIZE macros rather than Py_SIZE for concrete types. ↵Serhiy Storchaka2017-03-211-2/+2

* Backed out changeset b9c9691c72c5Victor Stinner2016-12-041-5/+5
| | | | | | Issue #28858: The change b9c9691c72c5 introduced a regression. It seems like _PyObject_CallArg1() uses more stack memory than PyObject_CallFunctionObjArgs().
* Replace PyObject_CallFunctionObjArgs() with fastcallVictor Stinner2016-12-011-5/+5
| | | | | | | | | | | | | | * PyObject_CallFunctionObjArgs(func, NULL) => _PyObject_CallNoArg(func) * PyObject_CallFunctionObjArgs(func, arg, NULL) => _PyObject_CallArg1(func, arg) PyObject_CallFunctionObjArgs() allocates 40 bytes on the C stack and requires extra work to "parse" C arguments to build a C array of PyObject*. _PyObject_CallNoArg() and _PyObject_CallArg1() are simpler and don't allocate memory on the C stack. This change is part of the fastcall project. The change on listsort() is related to the issue #23507.
