Add untokenize() function to allow full round-trip tokenization.
Should significantly enhance the utility of the module by supporting
the creation of tools that modify the token stream and writeback the
modified result.
[Bug #1074261, patch #1074381] Restrict the size of chunks read from the file in order to avoid overflow or huge memory consumption. Patch by Mark Eichin
change set_bt_compare() callback comparison function to only take two
arguments (left, right) like any sane comparison function. no need to
pass in the db object as an argument.
pybsddb 4.3.2:
* the has_key() method was not raising a DBError when a database error
had occurred. [SF patch id 1212590]
* added a wrapper for the DBEnv.set_lg_regionmax method [SF patch id 1212590]
* DBKeyEmptyError now derives from KeyError just like DBNotFoundError.
* internally everywhere DB_NOTFOUND was checked for has been updated
to also check for DB_KEYEMPTY. This fixes the semantics of a couple
operations on recno and queue databases to be more intuitive and results
in less unexpected DBKeyEmptyError exceptions being raised.
Adds 2 new type codes for marshal (binary floats and binary complexes), a
new marshal version (2), updates MAGIC and fiddles the de-serializing of
code objects to be less likely to clobber the real reason for failing if
it fails.
[ 1181301 ] make float packing copy bytes when they can
which hasn't been reviewed, despite numerous threats to check it in
anyway if noone reviews it. Please read the diff on the checkin list,
at least!
The basic idea is to examine the bytes of some 'probe values' to see if
the current platform is a IEEE 754-ish platform, and if so
_PyFloat_{Pack,Unpack}{4,8} just copy bytes around.
A problem regarding importing symlinked modules was recently reported on the
Cygwin mailing list:
http://cygwin.com/ml/cygwin/2005-04/msg00257.html
The following test case demonstrates the problem:
$ ls -l
total 1
lrwxrwxrwx 1 jt None 6 Apr 23 13:32 bar.py -> foo.py
-rw-r--r-- 1 jt None 24 Apr 18 20:13 foo.py
$ python -c 'import bar'
Traceback (most recent call last):
File "<string>", line 1, in ?
ImportError: No module named bar
Since Cygwin's case_ok() uses a modified version of the Windows's version, the
symlinked bar module actually resolves to file foo.py instead of bar.py. This
obviously causes the matching code to fail (regardless of case).
The patch fixes this problem by making Cygwin use the Mac OS X case_ok()
instead of a modified Window's version.

This test relied on short-circuiting details of dictobject.py to avoid
crashing, and indirectly on the fact that hash codes in
random.randrange(1000000000) were very unlikely to exhibit collisions.
To see the problem, replace this number with 500 and observe the crash on
either del target[key] or del keys[i].
The fix prevents recursive mutation, just as in the key insertion case.

Incorporate a lightly edited version of the SocketServer module's docstring
into the docs and segregate the method descriptions for the various classes
into separate sections. Base on suggestion by Paul Rubin in c.l.py.
* Fixed incorrect wording: expression->exception
* Noted the specific exception reported by "raise" when the is nothing
to re-raise.
* Eliminated several instances of "e.g." as recommended in the style guide.
Make subclasses of int, long, complex, float, and unicode perform type
conversion using the proper magic slot (e.g., __int__()). Also move conversion
code out of PyNumber_*() functions in the C API into the nb_* function.

Make parse_makefile fallback to environment variables if nothing is
defined in the makefile. Get CFLAGS from the Makefile, instead of
getting OPT, BASE_CFLAGS and EXTRA_CFLAGS individually.

If the data read from the bytestream in readline() ends in a '\r' read one more
byte, even if the user has passed a size parameter. This extra byte shouldn't
cause a buffer overflow in the tokenizer. The original plan was to return a line
ending in '\r', which might be recognizable as a complete line and skip any '\n'
that was read afterwards. Unfortunately this didn't work, as the tokenizer only
recognizes '\n' as line ends, which in turn lead to joined lines and
SyntaxErrors, so this special treatment of a split '\r\n' has been dropped. (It
can only happen with a temporarily exhausted bytestream now anyway.)
Fixes parts of SF bugs #1163244 and #1175396.

As per discussion on python-dev, descriptors defined in C with a NULL setter
now raise AttributeError instead of TypeError, for consistency with their
pure-Python equivalent.
