* Issue #29507: Fix _PyObject_CallFunctionVa()Victor Stinner2017-02-101-2/+4
| | | | is_size_t test was reversed. Bug spotted by INADA Naoki.
* Optimize slots: avoid temporary PyMethodObjectVictor Stinner2017-02-092-58/+160
| | | | | | | | | | | | | | | | | | Issue #29507: Optimize slots calling Python methods. For Python methods, get the unbound Python function and prepend arguments with self, rather than calling the descriptor which creates a temporary PyMethodObject. Add a new _PyObject_FastCall_Prepend() function used to call the unbound Python method with self. It avoids the creation of a temporary tuple to pass positional arguments. Avoiding temporary PyMethodObject and avoiding temporary tuple makes Python slots up to 1.46x faster. Microbenchmark on a __getitem__() method implemented in Python: Median +- std dev: 121 ns +- 5 ns -> 82.8 ns +- 1.0 ns: 1.46x faster (-31%) Co-Authored-by: INADA Naoki <songofacandy@gmail.com>
* Fix PyCFunction_Call() performance issueVictor Stinner2017-02-091-4/+50
| | | | | | | Issue #29259, #29465: PyCFunction_Call() doesn't create anymore a redundant tuple to pass positional arguments for METH_VARARGS. Add a new cfunction_call() subfunction.
* Fix refleaks if Py_EnterRecursiveCall() failsVictor Stinner2017-02-081-1/+4

* Issue #29306: Fix usage of Py_EnterRecursiveCall()Victor Stinner2017-02-082-73/+90
| | | | | | | * *PyCFunction_*Call*() functions now call Py_EnterRecursiveCall(). * PyObject_Call() now calls directly _PyFunction_FastCallDict() and PyCFunction_Call() to avoid calling Py_EnterRecursiveCall() twice per function call
* Issue #29460: _PyArg_NoKeywords(), _PyArg_NoStackKeywords() andSerhiy Storchaka2017-02-061-3/+2
| | | | _PyArg_NoPositional() now are macros.
* Reduce load factor (from 66% to 60%) to improve effectiveness of linear probing.Raymond Hettinger2017-02-041-3/+3
| | | | | | | Decreased density gives better collision statistics (average of 2.5 probes in a full table versus 3.0 previously) and fewer occurences of starting a second possibly overlapping sequence of 10 linear probes. Makes resizes a little more frequent but each with less work (fewer insertions and fewer collisions).

* Issue #29383: reduce temporary interned unicodeINADA Naoki2017-01-281-3/+10
| | | | | | | | | | | | | | add_methods(), add_members(), and add_getset() used PyDict_SetItemString() to register descriptor to the type's dict. So descr_new() and PyDict_SetItemString() creates interned unicode from same C string. This patch takes interned unicode from descriptor, and use PyDict_SetItem() instead of PyDict_SetItemString(). python_startup_no_site: default: Median +- std dev: 12.7 ms +- 0.1 ms patched: Median +- std dev: 12.5 ms +- 0.1 ms

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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, /)
