- Do not compile unicodeobject, unicodectype, and unicodedata if Unicode is disabled
- check for Py_USING_UNICODE in all places that use Unicode functions

- add the types.StringTypes list
- remove Unicode literals from most tests.
And remove all the extern decls in the middle of .c files.
Apparently, it was excluded from the header file because it is
intended for internal use by the interpreter. It's still intended for
internal use and documented as such in the header file.
In the default branch, keep three ifs that are used if level == 0, the
most common case. Note that first if here is a slight optimization
for the 'O' format.
Second part of SF patch 426072.
Note that lots of code was re-indented.
Replace two-step of convertsimple() and convertsimple1() with
convertsimple() and helper converterr(), which is called to format
error messages when convertsimple() fails. The old code did all the
real work in convertsimple1(), but deferred error message formatting
to conversimple(). The result was paying the price of a second
function call on every call just to format error messages in the
failure cases.
Factor out of the buffer-handling code in convertsimple() and package
it as convertbuffer().
Add two macros to ease readability of Unicode coversions,
UNICODE_DEFAULT_ENCODING() and CONV_UNICODE, an error string.
The convertsimple() routine had awful indentation problems, primarily
because there were two tabs between the case line and the body of the
case statements. This patch reformats the entire function to have a
single tab between case line and case body, which makes the code
easier to read (and consistent with ceval). The introduction of
converterr() exacerbated the problem and prompted this fix.
Also, eliminate non-standard whitespace after opening paren and before
closing paren in a few if statements.
(This checkin is part of SF patch 426072.)

"s#" will now return a pointer to the default encoded string data
of the Unicode object instead of a pointer to the raw UTF-16
data.
The latter is still available via PyObject_AsReadBuffer().
The patch also adds an optimization for string objects which is
based on the fact that string objects return the raw character data
for getreadbuffer access and are always single-segment.
-32768..65535 is acceptable. Added B specifier (with values from
-128..255). No L added (which would have completed the set) because l
already accepts any value (and the letter L is taken for quadwords).
the Python Unicode implementation.
The internal buffer used for implementing the buffer protocol
is renamed to defenc to make this change visible. It now holds the
default encoded version of the Unicode object and is calculated
on demand (NULL otherwise).
Since the default encoding defaults to ASCII, this will mean that
Unicode objects which hold non-ASCII characters will no longer
work on C APIs using the "s" or "t" parser markers. C APIs must now
explicitly provide Unicode support via the "u", "U" or "es"/"es#"
parser markers in order to work with non-ASCII Unicode strings.
(Note: this patch will also have to be applied to the 1.6 branch
of the CVS tree.)
comments, docstrings or error messages. I fixed two minor things in
test_winreg.py ("didn't" -> "Didn't" and "Didnt" -> "Didn't").
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 ;)
This patch fixes a problem on AIX with the signed int case code in
getargs.c, after Trent Mick's intervention about MIN/MAX overflow
checks. The AIX compiler/optimizer generates bogus code with the
default flags "-g -O" causing test_builtin to fail: int("10", 16) <>
16L. Swapping the two checks in the signed int code makes the problem
go away.
Also, make the error messages fit in 80 char lines in the
source.
Limit the 'b' formatter of PyArg_ParseTuple to valid values of an unsigned
char, i.e. [0,UCHAR_MAX]. It is expected that this is the common usage of 'b'.
An OverflowError is raised if the parsed value is outside this range.
Changes the 'b', 'h', and 'i' formatters in PyArg_ParseTuple to raise an
Overflow exception if they overflow (previously they just silently
overflowed).
Changes by Guido: always accept values [0..255] (in addition to
[CHAR_MIN..CHAR_MAX]) for 'b' format; changed some spaces into tabs in
other code.
Added 'u' and 'u#' tags for PyArg_ParseTuple - these turn a
PyUnicodeObject argument into a Py_UNICODE * buffer, or a Py_UNICODE *
buffer plus a length with the '#'. Also added an analog to 'U'
for Py_BuildValue.
Fixed a memory leak found by Fredrik Lundh. Instead of
PyUnicode_AsUTF8String() we now use _PyUnicode_AsUTF8String() which
returns the string object without incremented refcount (and assures
that the so obtained object remains alive until the Unicode object is
garbage collected).
The attached patch set includes a workaround to get Python with
Unicode compile on BSDI 4.x (courtesy Thomas Wouters; the cause
is a bug in the BSDI wchar.h header file) and Python interfaces
for the MBCS codec donated by Mark Hammond.
Also included are some minor corrections w/r to the docs of
the new "es" and "es#" parser markers (use PyMem_Free() instead
of free(); thanks to Mark Hammond for finding these).
The unicodedata tests are now in a separate file
(test_unicodedata.py) to avoid problems if the module cannot
be found.
Attached you find the latest update of the Unicode implementation.
The patch is against the current CVS version.
It includes the fix I posted yesterday for the core dump problem
in codecs.c (was introduced by my previous patch set -- sorry),
adds more tests for the codecs and two new parser markers
"es" and "es#".
The MS compiler doesn't call it 'long long', it uses __int64,
so a new #define, LONG_LONG, has been added and all occurrences
of 'long long' are replaced with it.

Subject: getargs bug in 1.2 and 1.3 BETA
We have found a bug in the part of the getargs code that we added
and submitted, and which was incorporated into 1.1.
The parsing of "O?" format specifiers is not handled correctly;
there is no "else" for the "if" and therefore it can never fail.
What's worse, the advancing of the varargs pointer is not
handled properly, so from then on it is out of sync, wreaking
all sorts of havoc. (If it had failed properly, then the out-of-sync
varargs would not have been an issue.)
Below is the context diff for the change.
Note that I have made a few stylistic changes beyond adding the
else case, namely:
1) Making the "O" case follow the convention established by the other
format specifiers of getting all their vararg arguments before
performing the test, rather than getting some before and some after
the test passes.
2) Making the logic of the tests parallel, so the "if" part indicates
that the format is accepted and the "else" part indicates that the
format has failed. They were inconsistent with each other and with the
the other format specifiers.

Geoff Philbrick <philbric@delphi.hks.com> (slightly changed by me).
Also a little change to make the file acceptable to K&R C compilers
(HPUX, SunOS 4.x).
bltinmodule.c: fixed coerce() nightmare in ternary pow().
modsupport.c (initmodule2): pass METH_FREENAME flag to newmethodobject().
pythonrun.c: move flushline() into and around print_error().
Include/modsupport.h: moved getargs() to its own file and
re-implemented it entirely to support optional arguments, multiple
arguments without surrounding parentheses
(when called as newgetargs()), and better error messages
