| | | | | | | | | | | Issue #29311: dict.get() and dict.setdefault() methods now use Argument Clinic to parse arguments. Their calling convention changes from METH_VARARGS to METH_FASTCALL which avoids the creation of a temporary tuple. The signature of docstrings is also enhanced. For example, get(...) becomes: get(self, key, default=None, /)

| | | | | | | | | | | | | | | | | | | | | Issue #28147: Fix a memory leak in split-table dictionaries: setattr() must not convert combined table into split table. Patch written by INADA Naoki.
| * | Issue #28731: Optimize _PyDict_NewPresized() to create correct size dict.INADA Naoki2016-12-071-5/+19

* | | Backed out changeset b9c9691c72c5Victor Stinner2016-12-041-1/+2
| | | | | | | | | | | | | | | | | | 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 Stinner2016-12-011-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.
