This patch adds a new configure argument on OSX:
--with-universal-archs=[32-bit|64-bit|all]
When used with the --enable-universalsdk option this controls which
CPU architectures are includes in the framework. The default is 32-bit,
meaning i386 and ppc. The most useful alternative is 'all', which includes
all 4 CPU architectures supported by MacOS X (i386, ppc, x86_64 and ppc64).
This includes limited support for the Carbon bindings in 64-bit mode as well,
limited because (a) I haven't done extensive testing and (b) a large portion
of the Carbon API's aren't available in 64-bit mode anyway.
I've also duplicated a feature of Apple's build of python: setting the
environment variable 'ARCHFLAGS' controls the '-arch' flags used for building
extensions using distutils.
convention that allows safe access to errno)

errno (and LastError, on Windows).
ctypes maintains a module-global, but thread-local, variable that
contains an error number; called 'ctypes_errno' for this discussion.
This variable is a private copy of the systems 'errno' value; the copy
is swapped with the 'errno' variable on several occasions.
Foreign functions created with CDLL(..., use_errno=True), when called,
swap the values just before the actual function call, and swapped
again immediately afterwards. The 'use_errno' parameter defaults to
False, in this case 'ctypes_errno' is not touched.
The values are also swapped immeditately before and after ctypes
callback functions are called, if the callbacks are constructed using
the new optional use_errno parameter set to True: CFUNCTYPE(..., use_errno=TRUE)
or WINFUNCTYPE(..., use_errno=True).
Two new ctypes functions are provided to access the 'ctypes_errno'
value from Python:
- ctypes.set_errno(value) sets ctypes_errno to 'value', the previous
ctypes_errno value is returned.
- ctypes.get_errno() returns the current ctypes_errno value.
---
On Windows, the same scheme is implemented for the error value which
is managed by the GetLastError() and SetLastError() windows api calls.
The ctypes functions are 'ctypes.set_last_error(value)' and
'ctypes.get_last_error()', the CDLL and WinDLL optional parameter is
named 'use_last_error', defaults to False.
---
On Windows, TlsSetValue and TlsGetValue calls are used to provide
thread local storage for the variables; ctypes compiled with __GNUC__
uses __thread variables.
* Expand comments.
* Swap variable names in the sum_exact code so that x and y
are consistently chosen as the larger and smaller magnitude
values respectively.
Renamed copy_reg to copyreg in the standard library, to avoid
spurious warnings and ease later merging to py3k branch. Public
documentation remains intact.

being parsed as 'NUMBER', like expected. Also corrected the docs about
converter names being case-sensitive. They aren't any longer.
cmath module is loaded) instead of statically. This fixes compile-time
problems on platforms where HUGE_VAL is an extern variable rather than
a constant.
Thanks Hirokazu Yamamoto for the patch.
The patch also adds acosh, asinh, atanh, log1p and copysign to all platforms. Finally it fixes differences between platforms like different results or exceptions for edge cases. Have fun :)
'warnings' code in places where it was previously not possible (e.g., the
parser). It could also potentially lead to a speed-up in interpreter start-up
if the C version of the code (_warnings) is imported over the use of the
Python version in key places.
Closes issue #1631171.
-J and -X are now reserved for Jython and non-standard arguments (e.g. IronPython). I've added some extra comments to make sure the reservation don't get missed in the future.
It was only used as a helper in types.py to access types (GetSetDescriptorType and MemberDescriptorType),
when they can easily be obtained with python code.
These expressions even work with Jython.
I don't know what the future of the types module is; (cf. discussion in http://bugs.python.org/issue1605 )
at least this change makes it simpler.
I applied the same changes manually to VS7.1 and VC6 files; completely untested.
(Christian, don't try too hard merging this change into py3k.
It will be easier to do the same work again on the branch)

2.x signed value. Also, don't waste space on a table full of unsigned longs
when all it needs are unsigned ints (incase anyone builds this without zlib on
a 64-bit unix for some strange reason).
tested by forcing it to compile this version on both 32-bit and 64-bit linux.
platforms with a 64-bit long.
The Alpha/Tru64 test problem is a problem in either tarfile or test_tarfile,
not zlib.
crc32 and adler32 return 32-bit values. by using a long thats larger than
32-bits in these functions they were prevented from wrapping around to their
signed 32-bit value that we want them to return in python 2.x.
which made the return value signed. On the Alpha that also lost data
since sizeof(int) != sizeof(long) and apparently adler32/crc32 return
64 bits of data. This change keeps the signedness and continues to store the
data in a long rather than an int as was the case before r61449.
The patch adds wrappers for the Linux epoll syscalls and the BSD kqueue syscalls. Thanks to Thomas Herve and the Twisted people for their support and help.

regardless of the native sizeof(long) used in the integer object.
This somewhat odd behavior of returning a signed is maintained in 2.x for
compatibility reasons of always returning an integer rather than a long object.

The bundled libffi copy is now in sync with the recently released
libffi3.0.4 version, apart from some small changes to
Modules/_ctypes/libffi/configure.ac.
I gave up on using libffi3 files on os x.
Instead, static configuration with files from pyobjc is used.
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.
were two module_methods and the one used depended on the order the
modules were loaded. By making the test module_methods static,
it is not exported and the correct version is picked up.
* 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
and py3k. Any changes from here on should be made to trunk, and
changes will propogate to py3k).
function can be called recursively.
This was discussed in issue1020188.
In python codebase, all occurrences of Py_[X]DECREF(xxx->yyy) are suspect,
except when they appear in tp_new or tp_dealloc functions, or when
the member cannot be of a user-defined class.
Note that tp_init is not safe.
I do have a (crashing) example for every changed line.
Is it worth adding them to the test suite?
Example:
class SpecialStr(str):
def __del__(self):
s.close()
import cStringIO
s = cStringIO.StringIO(SpecialStr("text"))
s.close() # Segfault
First chapter of the Python 3.0 io framework back port: _fileio
The next step depends on a working bytearray type which itself depends on a backport of the nwe buffer API.
from the WeakValueDictionary was slower by nearly a factor of 3.
To avoid leaks, weakref proxies for the array types are put into the
cache dict, with weakref callbacks that removes the entries when the
type goes away.
