all, either to see whether the # of chars fit in an int, or that the
amount of memory needed fit in a size_t. Checking these is expensive, but
the alternative is silently wrong answers (as in the bug report) or
core dumps (which were easy to provoke using Unicode strings).
resized after creation. 0-length strings are usually shared
and _PyString_Resize() fails on these shared strings.
Fixes [ Bug #111667 ] unicode core dump.
Properly end a comment block. It was terminated fine later but by a subsequent

talking about it. :)
function (together with other locale aware ones) should into a new collation
support module. See python-dev for a discussion of this removal.
Note: This patch should also be applied to the 1.6 branch.
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.)
The UTF-8 decoder is still buggy (i.e. it doesn't pass Markus Kuhn's
stress test), mainly due to the following construct:
#define UTF8_ERROR(details) do { \
if (utf8_decoding_error(&s, &p, errors, details)) \
goto onError; \
continue; \
} while (0)
(The "continue" statement is supposed to exit from the outer loop,
but of course, it doesn't. Indeed, this is a marvelous example of
the dangers of the C programming language and especially of the C
preprocessor.)
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 ;)
value is calculated from the character values, in a way
that makes sure an 8-bit ASCII string and a unicode string
with the same contents get the same hash value.
(as a side effect, this also works for ISO Latin 1 strings).
for more details, see the python-dev discussion.
Fixed a bug in PyUnicode_Count() which would have caused a
core dump in case of substring coercion failure.
Synchronized .count() with the string method of the same name
to return len(s)+1 for s.count('').
Fixed %c formatting to check for one character arguments. Thanks
to Finn Bock for finding this bug.
Added a fix for bug PR#348 which originated from not resetting
the globals correctly in _PyUnicode_Fini().
Change the default encoding to 'ascii' (it was previously
defined as UTF-8).
Note: The implementation still uses UTF-8 to implement
the buffer protocol, so C APIs will still see UTF-8. This
is on purpose: rather than fixing the Unicode implementation,
the C APIs should be made Unicode aware.
Added support for user settable default encodings. The
current implementation uses a per-process global which
defines the value of the encoding parameter in case it
is set to NULL (meaning: use the default encoding).
Fix the string methods that implement slice-like semantics with
optional args (count, find, endswith, etc.) to properly handle
indeces outside [INT_MIN, INT_MAX]. Previously the "i" formatter
for PyArg_ParseTuple was used to get the indices. These could overflow.
This patch changes the string methods to use the "O&" formatter with
the slice_index() function from ceval.c which is used to do the same
job for Python code slices (e.g. 'abcabcabc'[0:1000000000L]).

For documentation read the comments in mymalloc.h and objimpl.h.
(This is not exactly what Vladimir posted to the patches list; I've
made a few changes, and Vladimir sent me a fix in private email for a
problem that only occurs in debug mode. I'm also holding back on his
change to main.c, which seems unnecessary to me.)
