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.

Thomas Wouters 49fd7fa443 Merge p3yk branch with the trunk up to revision 45595. This breaks a fair
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.

Tim Peters feec4533e2 Bug 1003935: xrange overflows
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.

Raymond Hettinger ef9bf4031a Tidied up the implementations of reversed (including the custom ones
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.

Guido van Rossum d4774fb6ef Untested code for 64-bit platforms. range_length() is declared as int
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).

Jeremy Hylton 938ace69a0 staticforward bites the dust.
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.

Guido van Rossum 3f56166b1a Rip out the fancy behaviors of xrange that nobody uses: repeat, slice,
contains, tolist(), and the start/stop/step attributes.  This includes
removing the 4th ('repeat') argument to PyRange_New().

Guido van Rossum 65e0b99b61 SF patch #103158 by Greg Ball: Don't do unsafe arithmetic in xrange
object.

This fixes potential overflows in xrange()'s internal calculations on
64-bit platforms.  The fix is complicated because the sq_length slot
function can only return an int; we want to support
xrange(sys.maxint), which is a 64-bit quantity on most 64-bit
platforms (except Win64).  The solution is hacky but the best
possible: when the range is that long, we can use it in a for loop but
we can't ask for its length (nor can we actually iterate beyond
2**31-1, because the sq_item slot function has the same restrictions
on its arguments.  Fixing those restrictions is a project for another
day...
