positional argument instead.

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.

Mark Dickinson 7c4e409d07 Issue #11734: Add support for IEEE 754 half-precision floats to the struct module. Original patch by Eli Stevens. 2016-09-03 17:21:29 +01:00
Serhiy Storchaka 16931c3559 Issue #26983: float() now always return an instance of exact float.
The deprecation warning is emitted if __float__ returns an instance of
a strict subclass of float.  In a future versions of Python this can
be an error.

Martin Panter eeb896c411 Issue #24802: Copy bytes-like objects to null-terminated buffers if necessary
This avoids possible buffer overreads when int(), float(), compile(), exec()
and eval() are passed bytes-like objects. Similar code is removed from the
complex() constructor, where it was not reachable.

Patch by John Leitch, Serhiy Storchaka and Martin Panter.

Zachary Ware a4b7a7548c Issue #3158: doctest can now find doctests in functions and methods
written in C.

As a part of this, a few doctests have been added to the builtins module
(on hex(), oct(), and bin()), a doctest has been fixed (hopefully on all
platforms) on float, and test_builtins now runs doctests in builtins.

Victor Stinner 1c8f059019 Issue #18520: Add a new PyStructSequence_InitType2() function, same than
PyStructSequence_InitType() except that it has a return value (0 on success,
-1 on error).

 * PyStructSequence_InitType2() now raises MemoryError on memory allocation failure
 * Fix also some calls to PyDict_SetItemString(): handle error

Victor Stinner 8f674ccd64 Close #17694: Add minimum length to _PyUnicodeWriter
* Add also min_char attribute to _PyUnicodeWriter structure (currently unused)
 * _PyUnicodeWriter_Init() has no more argument (except the writer itself):
   min_length and overallocate must be set explicitly
 * In error handlers, only enable overallocation if the replacement string
   is longer than 1 character
 * CJK decoders don't use overallocation anymore
 * Set min_length, instead of preallocating memory using
   _PyUnicodeWriter_Prepare(), in many decoders
 * _PyUnicode_DecodeUnicodeInternal() checks for integer overflow

Victor Stinner d3f0882dfb Issue #14744: Use the new _PyUnicodeWriter internal API to speed up str%args and str.format(args)
* Formatting string, int, float and complex use the _PyUnicodeWriter API. It
   avoids a temporary buffer in most cases.
 * Add _PyUnicodeWriter_WriteStr() to restore the PyAccu optimization: just
   keep a reference to the string if the output is only composed of one string
 * Disable overallocation when formatting the last argument of str%args and
   str.format(args)
 * Overallocation allocates at least 100 characters: add min_length attribute
   to the _PyUnicodeWriter structure
 * Add new private functions: _PyUnicode_FastCopyCharacters(),
   _PyUnicode_FastFill() and _PyUnicode_FromASCII()

The speed up is around 20% in average.

Kristján Valur Jónsson daa06544c8 Issue #14435: Remove special block allocation code from floatobject.c
PyFloatObjects are now allocated using PyObject_MALLOC like all other
internal types, but maintain a limited freelist of objects at hand for
performance.  This will result in more consistent memory usage by Python.
