Change WindowsError to carry the Win32 error code in winerror,
and the DOS error code in errno. Revert changes where
WindowsError catch blocks unnecessarily special-case OSError.

- Add new Warning class, ImportWarning

Thu, 27 Apr 2006 23:13:20 +0000

- Add new Warning class, ImportWarning

- Warn-raise ImportWarning when importing would have picked up a directory
as package, if only it'd had an __init__.py. This swaps two tests (for
case-ness and __init__-ness), but case-test is not really more expensive,
and it's not in a speed-critical section.

- Test for the new warning by importing a common non-package directory on
sys.path: site-packages

- In regrtest.py, silence warnings generated by the build-environment
because Modules/ (which is added to sys.path for Setup-created modules)
has 'zlib' and '_ctypes' directories without __init__.py's.

Fri, 21 Apr 2006 10:40:58 +0000

Merge p3yk branch with the trunk up to revision 45595. This breaks a fair
number of tests, all because of the codecs/_multibytecodecs issue described
here (it's not a Py3K issue, just something Py3K discovers):
http://mail.python.org/pipermail/python-dev/2006-April/064051.html

Hye-Shik Chang promised to look for a fix, so no need to fix it here. The
tests that are expected to break are:

test_codecencodings_cn
test_codecencodings_hk
test_codecencodings_jp
test_codecencodings_kr
test_codecencodings_tw
test_codecs
test_multibytecodec

This merge fixes an actual test failure (test_weakref) in this branch,
though, so I believe merging is the right thing to do anyway.

PEP 352 implementation. Creates a new base class, BaseException, which has an
added message attribute compared to the previous version of Exception. It is
also a new-style class, making all exceptions now new-style. KeyboardInterrupt
and SystemExit inherit from BaseException directly. String exceptions now
raise DeprecationWarning.

Stop producing or using OverflowWarning. PEP 237 thought this would
happen in 2.3, but nobody noticed it still was getting generated (the
warning was disabled by default). OverflowWarning and
PyExc_OverflowWarning should be removed for 2.5, and left notes all over
saying so.

Provide module attributes for functions defined in C and Python.

Fri, 31 Jan 2003 18:33:18 +0000

Provide __module__ attributes for functions defined in C and Python.

__module__ is the string name of the module the function was defined
in, just like __module__ of classes. In some cases, particularly for
C functions, the __module__ may be None.

Change PyCFunction_New() from a function to a macro, but keep an
unused copy of the function around so that we don't change the binary
API.

Change pickle's save_global() to use whichmodule() if __module__ is
None, but add the __module__ logic to whichmodule() since it might be
used outside of pickle.

Fix SF bug 610610 (reported by Martijn Pieters, diagnosed by Neal Norwitz).

The switch in Exception__str__ didn't clear the error if
PySequence_Size() raised an exception. Added a case -1 which clears
the error and falls through to the default case.

Iterators phase 1. This comprises:

new slot tp_iter in type object, plus new flag Py_TPFLAGS_HAVE_ITER
new C API PyObject_GetIter(), calls tp_iter
new builtin iter(), with two forms: iter(obj), and iter(function, sentinel)
new internal object types iterobject and calliterobject
new exception StopIteration
new opcodes for "for" loops, GET_ITER and FOR_ITER (also supported by dis.py)
new magic number for .pyc files
new special method for instances: __iter__() returns an iterator
iteration over dictionaries: "for x in dict" iterates over the keys
iteration over files: "for x in file" iterates over lines

TODO:

documentation
test suite
decide whether to use a different way to spell iter(function, sentinal)
decide whether "for key in dict" is a good idea
use iterators in map/filter/reduce, min/max, and elsewhere (in/not in?)

First, the allocated buffer was never freed after using it to create

comments, docstrings or error messages. I fixed two minor things in

There is a minor style issue involved: Guido seems to have preferred English
grammar (behaviour, honour) in a couple places. This patch changes that to
American, which is the more prominent style in the source. I prefer English
myself, so if English is preferred, I'd be happy to supply a patch myself ;)
