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.
Bugfix candidate, but I already backported this to 2.2.
In 2.3, this code remains in severe need of refactoring.
invalid, rather than returning a string of random garbage of the
estimated result length. Closes SF patch #703471 by Hye-Shik Chang.
Will backport to 2.2-maint (consider it done.)
ALERT! A month ago or so I made test_ossaudiodev.py require the
'audio' resource, but I didn't make the necessary changes to
regrtest.py. This means that *nobody* has been testing the oss module
all that time!

To prevent code duplication, I patched _strptime to use datetime's date
object to do Julian day, Gregorian, and day of the week calculations.
Patch also includes new regression tests to test results and the
calculation gets triggered.
Very minor comment changes and the contact email are also changed.
* Adds missing pop() methods to weakref.py
* Expands test suite to broaden coverage of objects with
a mapping interface.

Quoting the path doesn't work on Win2K (cmd.exe) regardless, this is just
a hack to let the test pass again on Win2K (so long as Python isn't
installed in a path that does contain an embedded space). On Win2K it
looks like we'd also have to add a second pair of double quotes, around
the entire command line.
- the test was sloppy about filenames: "0-REGTYPE-TEXT" was used where
the archive held "/0-REGTYPE-TEXT".
- tarfile extracts all files in binary mode, but the test expected to be able to
read and compare text files in text mode. Use universal text mode.
[ 555817 ] Flawed fcntl.ioctl implementation.
with my patch that allows for an array to be mutated when passed
as the buffer argument to ioctl() (details complicated by
backwards compatibility considerations -- read the docs!).
assertRaises. Fixed a repeated subtle bug in the inplace tests by
removing the possibilty that a self.fail() call could raise a
TypeError that the test catches by mistake.
Allow mixed-type __eq__ and __ne__ for Set objects. This is messier than
I'd like because Set *also* implements __cmp__. I know of one glitch now:
cmp(s, t) returns 0 now when s and t are both Sets and s == t, despite
that Set.__cmp__ unconditionally raises TypeError (and by intent). The
rub is that __eq__ gets tried first, and the x.__eq__(y) True result
convinces Python that cmp(x, y) is 0 without even calling Set.__cmp__.
rarely needed, but can sometimes be useful to release objects
referenced by the traceback held in sys.exc_info()[2]. (SF patch
#693195.) Thanks to Kevin Jacobs!
