* Remove useless variable initializationVictor Stinner2016-12-091-9/+6
| | | | Don't initialize variables which are not used before they are assigned.
* Use PyObject_CallFunctionObjArgs()Victor Stinner2016-12-092-2/+2
| | | | | | | | | Issue #28915: Replace PyObject_CallFunction() with PyObject_CallFunctionObjArgs() when the format string was only made of "O" formats, PyObject* arguments. PyObject_CallFunctionObjArgs() avoids the creation of a temporary tuple and doesn't have to parse a format string.
* Use _PyObject_FastCallVa() in type slotsVictor Stinner2016-12-081-81/+50
| | | | | Issue #28915: Replace Py_VaBuildValue()+PyObject_Call() with _PyObject_FastCallVa() to avoid the creation of temporary tuple.
* Add _PyObject_VaCallFunctionObjArgs() private functionVictor Stinner2016-12-081-5/+5
| | | | | Issue #28915: Similar to _PyObject_CallFunctionObjArgs() but use va_list to pass arguments.
* Use _PyObject_CallMethodIdObjArgs()Victor Stinner2016-12-081-1/+2
| | | | | | | | | Issue #28915: Replace _PyObject_CallMethodId() with _PyObject_CallMethodIdObjArgs() when the format string only use the format 'O' for objects, like "(O)". _PyObject_CallMethodIdObjArgs() avoids the code to parse a format string and avoids the creation of a temporary tuple.
* _PyObject_CallFunctionVa() uses fast callVictor Stinner2016-12-081-9/+25
| | | | | | | | Issue #28915: Use _Py_VaBuildStack() to build a C array of PyObject* and then use _PyObject_FastCall(). The function has a special case if the stack only contains one parameter and the parameter is a tuple: "unpack" the tuple of arguments in this case.
* Add _PyObject_CallFunctionVa() helperVictor Stinner2016-12-081-54/+29
| | | | | | | | | Issue #28915: Add _PyObject_CallFunctionVa() helper to factorize code of functions: * PyObject_CallFunction() * _PyObject_CallFunction_SizeT() * callmethod()
* Add _PyObject_FastCallVa() helperVictor Stinner2016-12-081-71/+37
| | | | | | | | | | | Issue #28915: Add _PyObject_FastCallVa() helper to factorize code of functions: * PyObject_CallFunctionObjArgs() * PyObject_CallMethodObjArgs() * _PyObject_CallMethodIdObjArgs() Inline objargs_mkstack() into _PyObject_FastCallVa(), remove objargs_mkstack().

* | | _PyObject_FastCallKeywords() now calls directly tp_callVictor Stinner2016-12-061-15/+45
| | | | | | | | | | | | | | | _PyObject_FastCallKeywords() doesn't call _PyObject_FastCallDict() anymore: call directly tp_call.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue #28838: Rename parameters of the "calls" functions of the Python C API. * Rename 'callable_object' and 'func' to 'callable': any Python callable object is accepted, not only Python functions * Rename 'method' and 'nameid' to 'name' (method name) * Rename 'o' to 'obj' * Move, fix and update documentation of PyObject_CallXXX() functions in abstract.h * Update also the documentaton of the C API (update parameter names)

| | | | | | | | | | | | | | | | | | | | | | | | Modify type_setattro() to call directly _PyObject_GenericSetAttrWithDict() instead of PyObject_GenericSetAttr(). PyObject_GenericSetAttr() is a thin wrapper to _PyObject_GenericSetAttrWithDict().
* | | Issue #28858: Remove _PyObject_CallArg1() macroVictor Stinner2016-12-054-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace _PyObject_CallArg1(func, arg) with PyObject_CallFunctionObjArgs(func, arg, NULL) Using the _PyObject_CallArg1() macro increases the usage of the C stack, which was unexpected and unwanted. PyObject_CallFunctionObjArgs() doesn't have this issue.

| * | Issue #23722: improve __classcell__ compatibilityNick Coghlan2016-12-051-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Handling zero-argument super() in __init_subclass__ and __set_name__ involved moving __class__ initialisation to type.__new__. This requires cooperation from custom metaclasses to ensure that the new __classcell__ entry is passed along appropriately. The initial implementation of that change resulted in abruptly broken zero-argument super() support in metaclasses that didn't adhere to the new requirements (such as Django's metaclass for Model definitions). The updated approach adopted here instead emits a deprecation warning for those cases, and makes them work the same way they did in Python 3.5. This patch also improves the related class machinery documentation to cover these details and to include more reader-friendly cross-references and index entries.
* | | Backed out changeset b9c9691c72c5Victor Stinner2016-12-0417-30/+40
| | | | | | | | | | | | | | | | | | Issue #28858: The change b9c9691c72c5 introduced a regression. It seems like _PyObject_CallArg1() uses more stack memory than PyObject_CallFunctionObjArgs().
* | | Replace PyObject_CallFunction() with fastcallVictor Stinner2016-12-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace PyObject_CallFunction(func, "O", arg) and PyObject_CallFunction(func, "O", arg, NULL) with _PyObject_CallArg1(func, arg) Replace PyObject_CallFunction(func, NULL) with _PyObject_CallNoArg(func) _PyObject_CallNoArg() and _PyObject_CallArg1() are simpler and don't allocate memory on the C stack.
* | | Replace PyObject_CallFunctionObjArgs() with fastcallVictor Stinner2016-12-0117-40/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.
