has grown beyond what font-lock will work with using the default (X)Emacs
settings.
Indentation of the description has been made consistent, and a number of
smaller markup adjustments have been made as well.
introduced in Python 2.2.
Add documentation for the slice object interface (not complete).
Added version annotations for several of the Python 2.2 APIs already
documented.
Moved the PyArg_Parse*(), Py_BuildValue() functions to the Utilities
chapter, added a minimal description and reference to the Extending
manual for Py_BuildValue().
PyObject_InitVar(), PyObject_Del(), PyObject_NEW(),
PyObject_NEW_VAR(), and PyObject_DEL().
Add notes to PyMem_Malloc() and PyMem_New() about the memory buffers
not being initialized.
This fixes SF bug #439012.
Added explicit return value information for PyList_SetItem(),
PyDict_SetItem(), and PyDict_SetItemString(). Corrected return type
for PyList_SET_ITEM().
Fixed index entries in the descriptions of PyLong_AsLong() and
PyLong_AsUnignedLong().
This fixes the API manual portion of SF bug #440037.
Note that the headers properly declare everything as 'extern "C"' for
C++ users.
Document _Py_NoneStruct.
Added links to the Extending & Embedding manual for PyArg_ParseTuple()
and PyArg_ParseTupleAndKeywords().
Added note that PyArg_Parse() should not be used in new code.
Fix up a few style nits -- avoid "e.g." and "i.e." -- these make
translation more difficult, as well as reading the English more
difficult for non-native speakers.
PySequence_Size(), not PyObject_Size(): the later considers the mapping
methods as well as the sequence methods, which is not needed here. Either
should be equally fast in this case, but PySequence_Size() offers a better
conceptual match.
state *which* other function the current one is like, even if the
descriptions are adjacent.
Revise the _PyTuple_Resize() description to reflect the removal of the
third parameter.
and introduces a new method .decode().
The major change is that strg.encode() will no longer try to convert
Unicode returns from the codec into a string, but instead pass along
the Unicode object as-is. The same is now true for all other codec
return types. The underlying C APIs were changed accordingly.
Note that even though this does have the potential of breaking
existing code, the chances are low since conversion from Unicode
previously took place using the default encoding which is normally
set to ASCII rendering this auto-conversion mechanism useless for
most Unicode encodings.
The good news is that you can now use .encode() and .decode() with
much greater ease and that the door was opened for better accessibility
of the builtin codecs.
As demonstration of the new feature, the patch includes a few new
codecs which allow string to string encoding and decoding (rot13,
hex, zip, uu, base64).

patch for sharing single character Unicode objects.
Martin's patch had to be reworked in a number of ways to take Unicode
resizing into consideration as well. Here's what the updated patch
implements:
* Single character Unicode strings in the Latin-1 range are shared
(not only ASCII chars as in Martin's original patch).
* The ASCII and Latin-1 codecs make use of this optimization,
providing a noticable speedup for single character strings. Most
Unicode methods can use the optimization as well (by virtue
of using PyUnicode_FromUnicode()).
* Some code cleanup was done (replacing memcpy with Py_UNICODE_COPY)
* The PyUnicode_Resize() can now also handle the case of resizing
unicode_empty which previously resulted in an error.
* Modified the internal API _PyUnicode_Resize() and
the public PyUnicode_Resize() API to handle references to
shared objects correctly. The _PyUnicode_Resize() signature
changed due to this.
* Callers of PyUnicode_FromUnicode() may now only modify the Unicode
object contents of the returned object in case they called the API
with NULL as content template.
Note that even though this patch passes the regression tests, there
may still be subtle bugs in the sharing code.
