* | | Add _PY_FASTCALL_SMALL_STACK constantVictor Stinner2016-12-151-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Issue #28870: Add a new _PY_FASTCALL_SMALL_STACK constant, size of "small stacks" allocated on the C stack to pass positional arguments to _PyObject_FastCall(). _PyObject_Call_Prepend() now uses a small stack of 5 arguments (40 bytes) instead of 8 (64 bytes), since it is modified to use _PY_FASTCALL_SMALL_STACK.

| | | | | | | | | | | | | | | | | | | | | Special thanks to INADA Naoki for pushing the patch through the last mile, Serhiy Storchaka for reviewing the code, and to Victor Stinner for suggesting the idea (originally implemented in the PyPy project).

* | | Inline PyEval_EvalFrameEx() in callersVictor Stinner2016-12-091-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | The PEP 523 modified PyEval_EvalFrameEx(): it's now an indirection to interp->eval_frame(). Inline the call in performance critical code. Leave PyEval_EvalFrame() unchanged, this function is only kept for backward compatibility.
* | | Use _PyObject_CallMethodIdObjArgs()Victor Stinner2016-12-093-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | Issue #28915: Replace _PyObject_CallMethodId() with _PyObject_CallMethodIdObjArgs() in various modules when the format string was only made of "O" formats, PyObject* arguments. _PyObject_CallMethodIdObjArgs() avoids the creation of a temporary tuple and doesn't have to parse a format string.
* | | Use _PyObject_CallMethodIdObjArgs()Victor Stinner2016-12-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* | | Add _Py_VaBuildStack() functionVictor Stinner2016-12-081-0/+98
| | | | | | | | | | | | | | | Issue #28915: Similar to Py_VaBuildValue(), but work on a C array of PyObject*, instead of creating a tuple.
* | | modsupport: replace int with Py_ssize_tVictor Stinner2016-12-081-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | Issue #28915: Py_ssize_t type is better for indexes. The compiler might emit more efficient code for i++. Py_ssize_t is the type of a PyTuple index for example. Replace also "int endchar" with "char endchar".
* | | modsupport: replace int with Py_ssize_tVictor Stinner2016-12-081-17/+20

* | | Uniformize argument names of "call" functionsVictor Stinner2016-12-062-7/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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)
* | | Issue #28858: Remove _PyObject_CallArg1() macroVictor Stinner2016-12-054-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Coghlan2016-12-053-1184/+1218
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Stinner2016-12-045-10/+10
| | | | | | | | | | | | | | | | | | Issue #28858: The change b9c9691c72c5 introduced a regression. It seems like _PyObject_CallArg1() uses more stack memory than PyObject_CallFunctionObjArgs().

* | | WITH_CLEANUP_START uses fastcallVictor Stinner2016-12-011-3/+10

* | | Replace PyObject_CallFunctionObjArgs() with fastcallVictor Stinner2016-12-015-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.
