e03e5b1f91 Remove assumption that cls is a subclass of dict. 
Simplifies the code and gets Just van Rossum's example to work.

61ce0a9bae slot_tp_hash(): In the normal path, this leaked a reference to the 
integer hash object returned by __hash__().  This accounts for some of
the "mystery leaks" in the sandbox datetime tests, but probably not
all of them.

a69c030c15 The final tweaks before closing 
[ 633152 ] list slice ass ignores subtypes of list

Allow arbitrary sequences on the RHS of extended slices.

b02bb5ed0a Replace BadInternalCall with TypeError. Add a test case. Fix whitespace. 
Just van Rossum showed a weird, but clever way for pure python code to
trigger the BadInternalCall.  The C code had assumed that calling a class
constructor would return an instance of that class; however, classes that
abuse __new__ can invalidate that assumption.

ade8c8b2c3 Nudge getting __module__ and __name__ for new-style classes so that 
the results of *setting* __name__ are not so surprising.

If people can suggest more tests, that'd be grand, or is what's there
sufficient?

7e7c00db0c I don't know why staring at the email to python-checkins made me 
see problems with my code that I didn't see before the checkin, but:

When a subtype .mro() fails, we need to reset the type whose __bases__
are being changed, too.  Fix + test.

Michael W. Hudson
586da8fddd Readjustments to the way we cope with exceptions from subclasses' 
mro() methods.  Now any exception aborts the whole __bases__ change.

And more tests.

ac74f5d44b Initialize a variable. Hope this makes things work for Guido. 
It's odd that gcc on my ibook didn't complain about this.

98bbc49c54 This is my patch: 
[ 635933 ] make some type attrs writable

Plus a couple of extra tests beyond what's up there.

It hasn't been as carefully reviewed as it perhaps should, so all readers
are encouraged, nay exhorted, to give this a close reading.

There are still a couple of oddities related to assigning to __name__,
but I intend to solicit python-dev's opinions on these.

98f3373a8c A tweaked version of Jeremy's patch #642489, to produce better error 
messages about MRO conflicts.  (The tweaks include correcting spelling
errors, some refactoring to get the name of classic classes, and a
style nit or two.)

7d791240c0 float_int(): Some systems raise an exception if a double is cast to 
long but the double is too big to fit in a long.  Prevent that.  This
closes some recent bug or patch on SF, but SF is down now so I can't
say which.

Bugfix candidate.

f171540ab8 Change int() so that passing a string, unicode, float or long argument 
that is outside the integer range no longer raises OverflowError, but
returns a long object instead.

26db587485 str and unicode objects now have a __mod__ slot so don't special case them in 
PyNumber_Remainder().  This fixes SF bug #615506 and allows string and unicode

89350a41b9 Remove _Py_ResetReferences. Fixes bug #529750 "Circular reference makes

Py_Finalize() and Py_Initialize() if they are kept alive by circular
references.

1f1213120e Use the new C3 MRO algorithm, implemented by Samuele Pedroni (SF patch 
619475; also closing SF bug 618704).  I tweaked his code a bit for
style.

This raises TypeError for MRO order disagreements, which is an
improvement (previously these went undetected) but also a degradation:
what if the order disagreement doesn't affect any method lookups?
I don't think I care.

80a1bf4b5d Fix SF # 635969, No error "not all arguments converted" 
When mwh added extended slicing, strings and unicode became mappings.
Thus, dict was set which prevented an error when doing:
	newstr = 'format without a percent' % string_value

This fix raises an exception again when there are no formats
and % with a string value.

b9099c3df4 SF patch 637176: list.sort crasher 
Armin Rigo's Draconian but effective fix for

SF bug 453523: list.sort crasher

slightly fiddled to catch more cases of list mutation.  The dreaded
internal "immutable list type" is gone!  OTOH, if you look at a list
*while* it's being sorted now, it will appear to be empty.  Better
than a core dump.

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!).
