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.
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.

the Python Windows installer finally has an attractive Pythonic bitmap
to delight the senses and dampen the fears of the millions and millions of
eager new Windows users anticipating their first Python programming joy.
Always knew Mac users secretly wanted to switch to Windows <wink>.
In the Wise installer's "Advanced Options" dialog, substitute in the
actual name of "the system directory" -- this is clearer, and especially
for people reading this dialog who aren't me <wink>.
- 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
(fix by Tony Lownds)
- Don't use the Mac subtree anymore, the routines relevant to OSX/Darwin
have moved to a new file Python/mactoolboxglue.c.
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).
If 'unittest.py' was run from the command line with the name of a test
case class as a parameter, it failed with an ugly error. (Which was a
shame, because the documentation says you can do that.)
The problem was the old 'is the class X that you imported from me the same
as my class X?' gotcha.
This introduces:
- 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.
