Complex numbers implement divmod() and //, neither of which makes one
lick of sense.  Unfortunately this is documented, so I'm adding a
deprecation warning now, so we can delete this silliness, oh, around
2005 or so.

Bugfix candidate (At least for 2.2.2, I think.)

A stupid bug in object_set_class(): didn't check for value==NULL
before checking its type.

Bugfix candidate.

#543674.

Bugfix candidate.

In DatagramRequestHandler.setup(), the wfile initialization should be
StringIO.StringIO(), not StringIO.StringIO(slf.packet).

Bugfix candidate (all the way back to Python 1.5.2 :-).

When os.stat() for a file raises OSError, turn it into IOError per
documentation.

Bugfix candidate.

The problem was that an exception can occur in the text.get() call or
in the write() call, when the text buffer contains non-ASCII
characters.  This causes the previous contents of the file to be lost.

The provisional fix is to call str(self.text.get(...)) *before*
opening the file, so that if the exception occurs, we never open the
file.

Two orthogonal better solutions have to wait for policy decisions:

1. We could try to encode the data as Latin-1 or as UTF-8; but that
   would require IDLE to grow a notion of file encoding which requires
   more thought.

2. We could make backups before overwriting a file.  This requires
   more thought because it needs to be fast and cross-platform and
   configurable.

complex_subtype_from_string():  this stopped parsing at the first 0
byte, as if that were the end of the input string.

Bugfix candidate.

Highlights: import and friends will understand any of \r, \n and \r\n
as end of line. Python file input will do the same if you use mode 'U'.
Everything can be disabled by configuring with --without-universal-newlines.

See PEP278 for details.

Added code to call this when PYMALLOC_DEBUG is enabled, and envar
PYTHONMALLOCSTATS is set, whenever a new arena is obtained and once
late in the Python shutdown process.

Put a bound on the number of frameobjects that can live in the
frameobject free_list.

Am also backporting to 2.2.  I don't intend to backport to 2.1 (too
much work -- lots of cyclic structures leak there, and the GC API).

methods.
Part of SF feature #444708.

Add optional arg to string methods strip(), lstrip(), rstrip().
The optional arg specifies characters to delete.

Also for UserString.

Still to do:

- Misc/NEWS
- LaTeX docs (I did the docstrings though)
- Unicode methods, and Unicode support in the string methods.

_PyObject_DebugMalloc:  explicitly cast PyObject_Malloc's result to the
target pointer type.

_PyObject_DebugDumpStats:  change decl of arena_alignment from unsigned
int to unsigned long.

This is for the 2.3 release only (it's new code).

(The real issue is whether modules can benefit from an alternate
implementation strategy rather than using a dictionary.  We should migrate
away from direct dictionary manipulation to allow more room for Jeremy to
flex the implementation with changes in globals lookup.)

Clean up the example of exporting a C-callable API from an extension module.
Add a hyperlink to a related section in the Python/C API reference.

PyModule_GetDict(), which is also more flexible: it does not assume that the
"module" is a real module.

Change a section title to fit in better.
