Martin v. Löwis 6819210b9e PEP 3123: Provide forward compatibility with Python 3.0, while keeping
backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and
PyVarObject_HEAD_INIT.

Neal Norwitz 8a87f5d37e Patch #1538606, Patch to fix __index__() clipping.
I modified this patch some by fixing style, some error checking, and adding
XXX comments.  This patch requires review and some changes are to be expected.
I'm checking in now to get the greatest possible review and establish a
baseline for moving forward.  I don't want this to hold up release if possible.

Raymond Hettinger ea3fdf44a2 SF patch #659536: Use PyArg_UnpackTuple where possible.
Obtain cleaner coding and a system wide
performance boost by using the fast, pre-parsed
PyArg_Unpack function instead of PyArg_ParseTuple
function which is driven by a format string.

Michael W. Hudson cbd6fb9006 Handle really big steps in extended slices.
Fixes a test failure on 64 bit platforms (I hope).

Michael W. Hudson 173f11da5d Some days, I think my comment of
/* this is harder to get right than you might think */

angered some God somewhere.  After noticing

    >>> range(5000000)[slice(96360, None, 439)]
    []

I found that my cute test for the slice being empty failed due to
overflow.  Fixed, and added simple test (not the above!).

Michael W. Hudson f0d777c56b A few days ago, Guido said (in the thread "[Python-Dev] Python
version of PySlice_GetIndicesEx"):

> OK.  Michael, if you want to check in indices(), go ahead.

Then I did what was needed, but didn't check it in.  Here it is.

Guido van Rossum bea18ccde6 SF patch 568629 by Oren Tirosh: types made callable.
These built-in functions are replaced by their (now callable) type:

    slice()
    buffer()

and these types can also be called (but have no built-in named
function named after them)

    classobj (type name used to be "class")
    code
    function
    instance
    instancemethod (type name used to be "instance method")

The module "new" has been replaced with a small backward compatibility
placeholder in Python.

A large portion of the patch simply removes the new module from
various platform-specific build recipes.  The following binary Mac
project files still have references to it:

    Mac/Build/PythonCore.mcp
    Mac/Build/PythonStandSmall.mcp
    Mac/Build/PythonStandalone.mcp

[I've tweaked the code layout and the doc strings here and there, and
added a comment to types.py about StringTypes vs. basestring.  --Guido]

Michael W. Hudson 5efaf7eac8 This is my nearly two year old patch
[ 400998 ] experimental support for extended slicing on lists

somewhat spruced up and better tested than it was when I wrote it.

Includes docs & tests.  The whatsnew section needs expanding, and arrays
should support extended slices -- later.

Guido van Rossum d82fb78b5c Add values to tp_getattro and tp_flags so that dir(Ellipsis) will
return the same as dir(None).

Guido van Rossum 6f7993765a Add optional docstrings to member descriptors. For backwards
compatibility, this required all places where an array of "struct
memberlist" structures was declared that is referenced from a type's
tp_members slot to change the type of the structure to PyMemberDef;
"struct memberlist" is now only used by old code that still calls
PyMember_Get/Set.  The code in PyObject_GenericGetAttr/SetAttr now
calls the new APIs PyMember_GetOne/SetOne, which take a PyMemberDef
argument.

As examples, I added actual docstrings to the attributes of a few
types: file, complex, instance method, super, and xxsubtype.spamlist.

Also converted the symtable to new style getattr.

Guido van Rossum a1351fbd88 SF patch #408326 by Robin Thomas: slice objects comparable, not
hashable

This patch changes the behavior of slice objects in the following
manner:

- Slice objects are now comparable with other slice objects as though
they were logically tuples of (start,stop,step). The tuple is not
created in the comparison function, but the comparison behavior is
logically equivalent.

- Slice objects are not hashable. With the above change to being
comparable, slice objects now cannot be used as keys in dictionaries.

[I've edited the patch for style.  Note that this fixes the problem
that dict[i:j] seemed to work but was meaningless.  --GvR]

Guido van Rossum b18618dab7 Vladimir Marangozov's long-awaited malloc restructuring.
For more comments, read the patches@python.org archives.
For documentation read the comments in mymalloc.h and objimpl.h.

(This is not exactly what Vladimir posted to the patches list; I've
made a few changes, and Vladimir sent me a fix in private email for a
problem that only occurs in debug mode.  I'm also holding back on his
change to main.c, which seems unnecessary to me.)

Guido van Rossum e449af7da9 Ellipses -> Ellipsis rename (the dictionary really says that it should
be Ellipsis!).
Bumped the API version because a linker-visible symbol is affected.
Old C code will still compile -- there's a b/w compat macro.
Similarly, old Python code will still run, builtin exports both
Ellipses and Ellipsis.
