This commit rewrites the docstring for int() to incorporate the documentation
changes made in issue #16036. It also switches the docstrings for int(),
str(), range(), and slice() to use multi-line signatures.
the fast versions of range.__reversed__ and range iteration. Also
fix wrong results and a refleak for PyLong version of range.__reversed__.
Thanks Eric Smith for reviewing, and for suggesting improved tests.
Before the patch a lot of internal types weren't available in the header files. The patch exposes the new iterators, views and some other types to all C modules. I've also renamed some of the types and tp_names.
without calling PyType_Ready().
Question 1: Should the interpreter register all types with PyType_Ready()?
Many types seem to avoid it.
Question 2: To reproduce the problem, run the following code:
def f():
while True:
for a in iter(range(0,1,10**20)):
pass
f()
And watch the memory used by the process.
How do we test this in a unittest?
PyString_Concat() and PyString_ConcatAndDel() (the name PyUnicode_Concat()
was already taken).
Change PyObject_Repr() to always return a unicode object.
Update all repr implementations to return unicode objects.
Add a function PyObject_ReprStr8() that calls PyObject_Repr() and converts
the result to an 8bit string.
Use PyObject_ReprStr8() where using PyObject_Repr() can't be done
straightforward.

So long xrange. range() now supports values that are outside
-sys.maxint to sys.maxint. floats raise a TypeError.
This has been sitting for a long time. It probably has some problems and
needs cleanup. Objects/rangeobject.c now uses 4-space indents since
it is almost completely new.

number of tests, all because of the codecs/_multibytecodecs issue described
here (it's not a Py3K issue, just something Py3K discovers):
http://mail.python.org/pipermail/python-dev/2006-April/064051.html
Hye-Shik Chang promised to look for a fix, so no need to fix it here. The
tests that are expected to break are:
test_codecencodings_cn
test_codecencodings_hk
test_codecencodings_jp
test_codecencodings_kr
test_codecencodings_tw
test_codecs
test_multibytecodec
This merge fixes an actual test failure (test_weakref) in this branch,
though, so I believe merging is the right thing to do anyway.
Added XXX comment about why the undocumented PyRange_New() API function
is too broken to be worth the considerable pain of repairing.
Changed range_new() to stop using PyRange_New(). This fixes a variety
of bogus errors. Nothing in the core uses PyRange_New() now.
Documented that xrange() is intended to be simple and fast, and that
CPython restricts its arguments, and length of its result sequence, to
native C longs.
Added some tests that failed before the patch, and repaired a test that
relied on a bogus OverflowError getting raised.
for xrange and list objects).
* list.__reversed__ now checks the length of the sequence object before
calling PyList_GET_ITEM() because the mutable could have changed length.
* all three implementations are now tranparent with respect to length and
maintain the invariant len(it) == len(list(it)) even when the underlying
sequence mutates.
* __builtin__.reversed() now frees the underlying sequence as soon
as the iterator is exhausted.
* the code paths were rearranged so that the most common paths
do not require a jump.
but returns r->len which is a long. This doesn't even cause a warning
on 32-bit platforms, but can return bogus values on 64-bit platforms
(and should cause a compiler warning). Fix this by inserting a range
check when LONG_MAX != INT_MAX, and adding an explicit cast to (int)
when the test passes. When r->len is out of range, PySequence_Size()
and hence len() will report an error (but an iterator will still
work).
The staticforward define was needed to support certain broken C
compilers (notably SCO ODT 3.0, perhaps early AIX as well) botched the
static keyword when it was used with a forward declaration of a static
initialized structure. Standard C allows the forward declaration with
static, and we've decided to stop catering to broken C compilers. (In
fact, we expect that the compilers are all fixed eight years later.)
I'm leaving staticforward and statichere defined in object.h as
static. This is only for backwards compatibility with C extensions
that might still use it.
XXX I haven't updated the documentation.
handlers were both set, but were not compatible. This change uses only the
tp_getattro handler with a more "modern" approach.
This fixes SF bug #551285.
