This work is substantially Anthony Baxter's, from issue

This somewhat odd behavior of returning a signed is maintained in 2.x for

Added 0b and 0o literals to tokenizer.
Modified PyOS_strtoul to support 0b and 0o inputs.
Modified PyLong_FromString to support guessing 0b and 0o inputs.
Renamed test_hexoct.py to test_int_literal.py and added binary tests.
Added upper and lower case 0b, 0O, and 0X tests to test_int_literal.py
Added "Z" format_char to PyOS_ascii_formatd to support empty float presentation type.
Renamed buf_size in PyOS_ascii_formatd to more accurately reflect it's meaning.
Modified format.__float__ to use the new "Z" format as the default.
Added test cases.
Unlike Scheme where exactness is implemented as taints, the Python
implementation associated exactness with data types. This created
inheritance issues (making an exact subclass of floats would result
in the subclass having both an explicit Exact registration and an
inherited Inexact registration). This was a problem for the
decimal module which was designed to span both exact and inexact
arithmetic. There was also a question of use cases and no examples
were found where ABCs for exactness could be used to improve code.
One other issue was having separate tags for both the affirmative
and negative cases. This is at odds with the approach taken
elsewhere in the Python (i.e. we don't have an ABC both Hashable
and Unhashable).

My tests don't show the promised speed up of 10%. The code is as fast as the old code for simple cases and slightly faster for complex cases with several of args and kwargs. But the patch simplifies the code, too.
(This may fail on some slow platforms, but we can fix those cases which
should be relatively isolated and easier to find now.)

* Fix-up issues pointed-out by Neal Norwitz.
* Add extensive comments.
* The lz->result variable is now a tuple instead of a list.
* Use fast macro getitem/setitem calls so most code is in-line.
* Re-use the result tuple if available (modify in-place instead of copy).
Highlights:
- Adding PyObject_Format.
- Adding string.Format class.
- Adding __format__ for str, unicode, int, long, float, datetime.
- Adding builtin format.
- Adding ''.format and u''.format.
- str/unicode fixups for formatters.
The files in Objects/stringlib that implement PEP 3101 (stringdefs.h,
unicodedefs.h, formatter.h, string_format.h) are identical in trunk

They still remain fragile.
For example, a call to assertEqual currently does not make any allocation

* Convert both to unittest.
* Use the same unit testing code.

The mapping between bytecode offsets and source lines (lnotab) did not contain
an entry for the beginning of the loop.
Now it does, and the lnotab can be a bit larger:
in particular, several statements on the same line generate several entries.
However, this does not bother the settrace function, which will trigger only
one 'line' event.
The lnotab seems to be exactly the same as with python2.4.
I implemented the function sys._compact_freelists() and C API functions PyInt_/PyFloat_CompactFreeList() to compact the pre-allocated blocks of ints and floats. They allow the user to reduce the memory usage of a Python process that deals with lots of numbers.
The patch also renames sys._cleartypecache to sys._clear_type_cache
which isn't as bad as it sounds. The close() *should* raise an exception,
so if it didn't we should give more time to sync and really raise it.

global to determine when the server is ready to be used. This slows the test
down, but should make it correct. There was a race condition before where the
server could have assigned a port, yet it wasn't ready to serve requests. If
the client sent a request before the server was completely ready, it would get
an exception. There was machinery to try to handle this condition. All of
that should be unnecessary and removed if this change works. A NOTE was
added as a comment about what needs to be fixed.

useful primarily for teaching, but it also demonstrates how to implement a

I expect to write a couple more patches in this area:

* Rational.trim/approximate() (maybe with different names)
* Maybe remove the parentheses from Rational.__str__()
* Maybe rename one of the Rational classes
* Maybe make Rational('3/2') work.
Surprising behaviour of the "$" regexp: it matches the
end of the string, AND just before the newline at the end
of the string::
re.sub('$', '#', 'foo\n') == 'foo#\n#'
Python is consistent with Perl and the pcre library, so
we just document it.
Guido prefers "\Z" to match only the end of the string.
round included:
* Revert round to its 2.6 behavior (half away from 0).
* Because round, floor, and ceil always return float again, it's no
longer necessary to have them delegate to __xxx___, so I've ripped
that out of their implementations and the Real ABC. This also helps
in implementing types that work in both 2.6 and 3.0: you return int
from the __xxx__ methods, and let it get enabled by the version
upgrade.
* Make pow(-1, .5) raise a ValueError again.
* Make the _replace() method respect subclassing.

r58207 and r58247 patch logic is reversed. I noticed this when I
tried to use urllib to retrieve a file which required auth.
Fix that and add a test for 401 error to verify.
Also fix the test by having the test classes inherit from object.
Are the getter/setter/deleter attributes supposed to be able to chain? As of
right now they can't as the property tries to call what the property returns,
which is another property when they are chained.
This changes the rules for when __hash__ is inherited slightly,
by allowing it to be inherited when one or more of __lt__, __le__,
__gt__, __ge__ are overridden, as long as __eq__ and __ne__ aren't.
This adds signal.set_wakeup_fd(fd) which sets a file descriptor to
which a zero byte will be written whenever a C exception handler runs.
I added a simple C API as well, PySignal_SetWakeupFd(fd).
Issue #1580: New free format floating point representation based on "Floating-Point Printer Sample Code", by Robert G. Burger. For example repr(11./5) now returns '2.2' instead of '2.2000000000000002'.

Added a dictionary sys.float_info with information about the internal floating point type to the sys module.

fixes issue 1259.
For str only the stringobject.c file was modified. But for unicode,
I needed to repeat in the four functions a lot of code, so created
a new function that does part of the job for them (and placed it in
find.h, following a suggestion of Barry).
Also added tests for this behaviour.

Update the docs to reflect a previous change to the function name.
Add an example to the docs showing how to override the default __repr__ method.
Correction for issue1265 (pdb bug with "with" statement).
When an unfinished generator-iterator is garbage collected, PyEval_EvalFrameEx
is called with a GeneratorExit exception set. This leads to funny results
if the sys.settrace function itself makes use of generators.
A visible effect is that the settrace function is reset to None.
Another is that the eventual "finally" block of the generator is not called.
It is necessary to save/restore the exception around the call to the trace
function.
This happens a lot with py3k: isinstance() of an ABCMeta instance runs

"""Override for isinstance(instance, cls)."""

it closes itself. When the stream is read in several calls to read(n),
it should behave in the same way if HTTPConnection knows where the end

behaviour.
This should make the tests more robust at the expense of allowing
tests to be sloppier by not requiring them to cleanup after themselves.
(It will legitamitely help when running two test suites simultaneously

Backport abc.py and isinstance/issubclass overloading to 2.6.
I had to backport test_typechecks.py myself, and make one small change
to abc.py to avoid duplicate work when x.__class__ and type(x) are the
same.
Make sure the type of the return value of re.sub(x, y, z) is the type
of y+x (i.e. unicode if either is unicode, str if they are both str)
even if there are no substitutions or if x==z (which triggered various
special cases in join_list()).
Could be backported to 2.5; no need to port to 3.0.

- Specialcase step-1 extended slices to optimize the common case for all

as the step is 1. (Previously, 'l[:2:1] = []' failed even though
'l[:2] = []' and 'l[:2:None] = []' do not.)

that allows sending back exception/stack trace information about
