Windows when n is too big to fit in a 32-bit int. This was a hole in
2.2's large file support on Windows, and turns out it's a bad hole at
least for ZODB.
as "a bug" because there's no other way in core Python to ensure that
bytes written are actually on disk. At least ZODB wants this guarantee,
for robustness against crashes.
Fix SF bug #697220, string.strip implementation/doc mismatch
Attempt to make all the various string/unicode *strip methods the same.
* Doc - add doc for when functions were added
* UserString
* string/unicode object methods
* string module functions
'chars' is used for the last parameter everywhere.
pack_float, pack_double, save_float: All the routines for creating
IEEE-format packed representations of floats and doubles simply ignored
that rounding can (in rare cases) propagate out of a long string of
1 bits. At worst, the end-off carry can (by mistake) interfere with
the exponent value, and then unpacking yields a result wrong by a factor
of 2. In less severe cases, it can end up losing more low-order bits
than intended, or fail to catch overflow *caused* by rounding.
PyObject_Generic{Get,Set}Attr:
Don't access tp_descr_{get,set} of a descriptor without checking the
flag bits of the descriptor's type. While we know that the main type
(the type of the object whose attribute is being accessed) has all the
right flag bits (or else PyObject_Generic{Get,Set}Attr wouldn't be
called), we don't know that for its class attributes!
Provide access to the import lock, fixing SF bug #580952. This is
mostly from SF patch #683257, but I had to change unlock_import() to
return an error value to avoid fatal error.
Fix SF bug #667147, Segmentation fault printing str subclass
Fix infinite recursion which occurred when printing an object
whose __str__() returned self.
