SF patch #438013 Remove 2-byte Py_UCS2 assumptions
Removed all instances of Py_UCS2 from the codebase, and so also (I hope)
the last remaining reliance on the platform having an integral type
with exactly 16 bits.
PyUnicode_DecodeUTF16() and PyUnicode_EncodeUTF16() now read and write
one byte at a time.
Sigh. Strengthen the resriction of the previous checkin: tp_new is
inherited unless *both*: (a) the base type is 'object', and (b) the
subtype is not a "heap" type.
Thinking back to the 2.22 revision, I didn't like what I did there one
bit. For one, this class:
class C(object):
def __new__(myclass, ...): ...
would have no way to call the __new__ method of its base class, and
the workaround (to create an intermediate base class whose __new__ you
can call) is ugly.
So, I've come up with a better solution that restores object.__new__,
but still solves the original problem, which is that built-in and
extension types shouldn't inherit object.__new__. The solution is
simple: only "heap types" inherit tp_new. Simpler, less code,
perfect!
Previously, f.read() and f.readlines() checked for
errors on their file object and possibly raised an
IOError, but f.readline() didn't. This patch makes
f.readline() behave like the others.
Note that I've added a call to clearerr() since the other calls to
ferror() include that too.
For local files urllib.py doesn't return the MIME
headers that the documentation says it does:
http://www.python.org/doc/current/lib/module-
urllib.html#l2h-2187 states that "When the method is
local-file, returned headers will include a Date
representing the file's last-modified time, a Content-
Length giving file size, and a Content-Type containing
a guess at the file's type"
But in Python 2.1 the only header that gets returned
is the Content-Type:
Python's logolike module turtle.py did not display
the turtle except when actually drawing lines.
This patch changes the turtle.py module so that
it displays the turtle at all times when tracing is
on. This is similar to the the way that logo works.
When tracing is off the turtle will not be displayed.
Add get_objects function. This is a low level function (like
get_referents, and is not yet documented in the library manual).
Suggestions for a better name welcome.

Patch #437683: Use re instead of regex.
If multiple header files are processed simultaneously which include each
other, the corresponding modules mport each other. Specifically, if h2py
is invoked with sys/types.h first, later header files won't contain the
complete contents of TYPES.py.

Michael Hudson correctly pointed out we should cvsignore pyconfig.h, not
config.h (anymore). People will still have to delete config.h from their
source trees manually :)
Proper support for binary operators, including true division and floor
division. The basic binary operators now all correctly call the
__rxxx__ variant when they should.
In type_new(), I now make the new type a new-style number unless it
inherits from an old-style number that has numeric methods.
By way of cosmetics, I've changed the signatures of the SLOT<i> macros
to take actual function names and operator names as strings, rather
than rely on C preprocessor symbol manipulations. This makes the
calls slightly more verbose, but greatly helps simple searches through
the file: you can now find out where "__radd__" is used or where the
function slot_nb_power() is defined and where it is used.

Various fixes to streamline build process on Mac OS X:
- Give a warning if you're on a case-insensitive filesystem and have
not specified --with-suffix.
- Don't require --with-dyld, it is now default for OSX/Darwin (suggested
by Martin v. Loewis)
- Don't define _POSIX_THREADS on Darwin, it's done by standard headers already

Split macglue.c into two: a new mactoolboxglue.c (in ./Python)
with functionality needed for both unix-Python and MacPython and a
new smaller ./Mac/Python/macglue.c which contains MacPython stuff only.
pymactoolbox.h has moved to ./Include from ./Mac/Include and now also
contains the relevant stuff from macglue.h.
The net effect of this is that the ./Mac subdirectory is not needed
anymore for building the unix-Python core on MacOSX (it is needed
for building the extension modules).

Merged in bugfix from PyUnit CVS for problem reported by Gary Todd.
If 'unittest.py' was run from the command line with the name of a test

The problem was the old 'is the class X that you imported from me the same

Repair the Windows build (S_ISDIR() macro doesn't exist).
Somebody else should feel free to repair this a different way; see Python-
Dev for discussion.
- A new operator // that means floor division (the kind of division
where 1/2 is 0).
- The "future division" statement ("from __future__ import division)
which changes the meaning of the / operator to implement "true
division" (where 1/2 is 0.5).
- New overloadable operators __truediv__ and __floordiv__.
- New slots in the PyNumberMethods struct for true and floor division,
new abstract APIs for them, new opcodes, and so on.
I emphasize that without the future division statement, the semantics
of / will remain unchanged until Python 3.0.
Not yet implemented are warnings (default off) when / is used with int
or long arguments.
This has been on display since 7/31 as SF patch #443474.

Make sure XMLGenerator uses quoteattr() instead of escape() to quote

XML being generated. This makes sure it always produces the right thing.
Remove the __iter__ method from the UserDict class -- it can silently
break old code (in extreme cases). See SF bug #448153.
Add a new subclass IterableUserDict that has the __iter__ method.
Note that for new projects, unless backwards compatibility with
pre-2.2 Python is required, subclassing 'dictionary' is recommended;
UserDict might become deprecated.
- Add an explicit call to PyType_Ready(&PyList_Type) to pythonrun.c

ready all types, or none).
Add the NannyNag exception class and the process_tokens() function to

- Add comment blocks explaining add_operators() and override_slots().
(This file could use some more explaining, but this is all I had

- Renamed the argument 'base' of add_wrappers() to 'wraps' because
it's not a base class (which is what the 'base' identifier is used
for elsewhere).
Small nits:
- Fix add_tp_new_wrapper() to avoid overwriting an existing __new__
descriptor in tp_defined.
- In add_operators(), check the return value of add_tp_new_wrapper().
Functional change:
- Remove the tp_new functionality from PyBaseObject_Type; this means
you can no longer instantiate the 'object' type. It's only useful
as a base class.
- To make up for the above loss, add tp_new to dynamic types. This
has to be done in a hackish way (after override_slots() has been
called, with an explicit call to add_tp_new_wrapper() at the very
end) because otherwise I ran into recursive calls of slot_tp_new().
Sigh.
