Serhiy Storchaka c740e4fe8a bpo-30347: Stop crashes when concurrently iterate over itertools.groupby() iterators. (#1557) 2017-09-26 21:47:56 +03:00
Raymond Hettinger 49392c63a2 bpo-27385: Clarify docstring for groupby() (#3738) 2017-09-25 01:21:06 -07:00
Serhiy Storchaka c247caf33f bpo-30346: An iterator produced by the itertools.groupby() iterator (#1569) 
now becames exhausted after advancing the groupby iterator.

Serhiy Storchaka b3a77964ea bpo-27541: Reprs of subclasses of some classes now contain actual type name. (#3631) 
Affected classes are bytearray, array, deque, defaultdict, count and repeat.

Serhiy Storchaka 4ab46d7949 bpo-31497: Add private helper _PyType_Name(). (#3630) 
This function returns the last component of tp_name after a dot.
Returns tp_name itself if it doesn't contain a dot.

Serhiy Storchaka 6cca5c8459 bpo-30592: Fixed error messages for some builtins. (#1996) 
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.

Will Roberts 0ecdc52514 bpo-30537: use PyNumber in itertools.islice instead of PyLong (#1918) 
* 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

Serhiy Storchaka bf623ae884 bpo-30061: Check if PyObject_Size()/PySequence_Size()/PyMapping_Size() (#1096) 
raised an error.

Replace them with using concrete types API that never fails if appropriate.

T. Wouters 5466d4af5f bpo-29942: Fix the use of recursion in itertools.chain.from_iterable. (#889) 
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.

Serhiy Storchaka ba85d69a3e bpo-29878: Add global instances of int for 0 and 1. (#852) 2017-03-30 09:09:41 +03:00
Serhiy Storchaka fff9a31a91 bpo-29865: Use PyXXX_GET_SIZE macros rather than Py_SIZE for concrete types. (#748) 2017-03-21 08:53:25 +02:00
Serhiy Storchaka 5ab81d787f Issue #28959: Added private macro PyDict_GET_SIZE for retrieving the size of dict. 2016-12-16 16:18:57 +02:00
Victor Stinner de4ae3d486 Backed out changeset b9c9691c72c5 
Issue #28858: The change b9c9691c72c5 introduced a regression. It seems like
_PyObject_CallArg1() uses more stack memory than
PyObject_CallFunctionObjArgs().
 2016-12-04 22:59:09 +01:00
Victor Stinner 27580c1fb5 Replace PyObject_CallFunctionObjArgs() with fastcall 
* 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.

Serhiy Storchaka 1ed017ae92 Issue #20440: Cleaning up the code by using Py_SETREF and Py_CLEAR. 
Old code is correct, but with Py_SETREF and Py_CLEAR it can be cleaner.
This patch doesn't fix bugs and hence there is no need to backport it.
