Victor Stinner de4ae3d486 Backed out changeset b9c9691c72c5 
Issue #28858: The change b9c9691c72c5 introduced a regression. It seems like
_PyObject_CallArg1() uses more stack memory than
PyObject_CallFunctionObjArgs().
 2016-12-04 22:59:09 +01:00
Victor Stinner 27580c1fb5 Replace PyObject_CallFunctionObjArgs() with fastcall 
* 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.

Victor Stinner be75b8cf23 Issue #25349: Optimize bytes % int 
Optimize bytes.__mod__(args) for integere formats: %d (%i, %u), %o, %x and %X.
_PyBytesWriter is now used to format directly the integer into the writer
buffer, instead of using a temporary bytes object.

Formatting is between 30% and 50% faster on a microbenchmark.

Victor Stinner 5783fd2c58 Issue #24999: In longobject.c, use two shifts instead of ">> 2*PyLong_SHIFT" to 
avoid undefined behaviour when LONG_MAX type is smaller than 60 bits.

This change should fix a warning with the ICC compiler.

R David Murray 861470c836 #16518: Bring error messages in harmony with docs ("bytes-like object") 
Some time ago we changed the docs to consistently use the term 'bytes-like
object' in all the contexts where bytes, bytearray, memoryview, etc are used.
This patch (by Ezio Melotti) completes that work by changing the error
messages that previously reported that certain types did "not support the
buffer interface" to instead say that a bytes-like object is required.  (The
glossary entry for bytes-like object references the discussion of the buffer
protocol in the docs.)

Victor Stinner 45e8e2f218 Issue #21490: Add new C macros: Py_ABS() and Py_STRINGIFY()
