Victor Stinner 37e4ef7b17 Issue #27810: Rerun Argument Clinic on all modules 2016-09-09 20:00:13 -07:00
Victor Stinner a9efb2f56e Add METH_FASTCALL calling convention 
Issue #27810: Add a new calling convention for C functions:

    PyObject* func(PyObject *self, PyObject **args,
                   Py_ssize_t nargs, PyObject *kwnames);

Where args is a C array of positional arguments followed by values of keyword
arguments. nargs is the number of positional arguments, kwnames are keys of
keyword arguments. kwnames can be NULL.

Victor Stinner ae8b69c410 Issue #27810: Add _PyCFunction_FastCallKeywords()

Issue #27830: Add _PyObject_FastCallKeywords(): avoid the creation of a

Other changes:

* Cleanup call_function() and fast_function() (ex: rename nk to nkwargs)
* Remove now useless do_call(), replaced with _PyObject_FastCallKeywords()

Christian Heimes 07a2a1b7e5 Additional safe-guard against dereferencing NULL in reduce_newobj 
_PyObject_GetNewArguments() can leave args == NULL but the __newobj_ex__
branch expects args to be not-NULL.

 2016-09-09 00:21:22 +02:00
Christian Heimes 884332b45a Add NULL check for gen->gi_code in gen_send_ex() 
_PyGen_Finalize() checks that gen->gi_code is not NULL before it
accesses the flags of the code object. This means that the flag
could be NULL.

It passes down the generatore to gen_close() and gen_send_ex().
gen_send_ex() did not check for gen->gi_code != NULL.

Victor Stinner 942889aae2 Issue #27938: Add a fast-path for us-ascii encoding 
Other changes:

* Rewrite _Py_normalize_encoding() as a C implementation of
  encodings.normalize_encoding(). For example, " utf-8 " is now normalized to
  "utf_8". So the fast path is now used for more name variants of the same
  encoding.
* Avoid strcpy() when encoding is NULL: call directly the UTF-8 codec

Victor Stinner dd69564c38 PyObject_CallMethodObjArgs() now uses fast call 
Issue #27809:

* PyObject_CallMethodObjArgs(), _PyObject_CallMethodIdObjArgs() and
  PyObject_CallFunctionObjArgs() now use fast call to avoid the creation of a
  temporary tuple
* Rename objargs_mktuple() to objargs_mkstack()
* objargs_mkstack() now stores objects in a C array using borrowed references,
  instead of storing arguments into a tuple

objargs_mkstack() uses a small buffer allocated on the C stack for 5 arguments
or less, or allocates a buffer in the heap memory.

Note: this change is different than the change 0e4f26083bbb, I fixed the test
to decide if the small stack can be used or not. sizeof(PyObject**) was also
replaced with sizeof(stack[0]) since the sizeof() was wrong (but gave the same
result).

Victor Stinner 9be7e7b52f Add _PyObject_FastCall() 
Issue #27128: Add _PyObject_FastCall(), a new calling convention avoiding a
temporary tuple to pass positional parameters in most cases, but create a
temporary tuple if needed (ex: for the tp_call slot).

The API is prepared to support keyword parameters, but the full implementation
will come later (_PyFunction_FastCall() doesn't support keyword parameters
yet).

Add also:

* _PyStack_AsTuple() helper function: convert a "stack" of parameters to
  a tuple.
* _PyCFunction_FastCall(): fast call implementation for C functions
* _PyFunction_FastCall(): fast call implementation for Python functions

  several more) can be set to None in an implementation class and the
  behavior will be as if the method is not defined at all.
  (Previously, this mechanism existed only for __hash__, to make
  mutable classes unhashable.)  Code contributed by Andrew Barnert and
  Ivan Levkivskyi.

Raymond Hettinger 3625af5f21 Moved misplaced functions to the section for C API functions. 2016-03-27 01:15:07 -07:00
Raymond Hettinger 2c257ab0f8 Responsibility for argument checking belongs in set.__init__() rather than set.__new__(). 
See dict.__new__() and list.__new__() for comparison.  Neither of those examine or touch
args or kwds.  That work is done in the __init__() methods.

  compiled in release mode. It now has no effect if set to an empty string.
* In debug mode, debug hooks are now also installed on Python memory allocators
  when Python is configured without pymalloc.
