Victor Stinner ae8b69c410 Issue #27810: Add _PyCFunction_FastCallKeywords() 
Use _PyCFunction_FastCallKeywords() in ceval.c: it allows to remove a lot of
code from ceval.c which was only used to call C functions.

Benjamin Peterson 621b430a14 remove all usage of Py_LOCAL 2016-09-09 13:54:34 -07:00
Victor Stinner d873572095 Add _PyObject_FastCallKeywords() 
Issue #27830: Add _PyObject_FastCallKeywords(): avoid the creation of a
temporary dictionary for keyword arguments.

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 ad8c83ad6b Avoid inefficient way to call functions without argument

string to produce 0 argument.

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).
