a doubly-linked list, exposed by sys.getobjects(). Unfortunately, it's not
really all live objects, and it seems my fate to bump into programs where
sys.gettotalrefcount() keeps going up but where the reference leaks aren't
accounted for by anything in the list of all objects.
This patch helps a little: if COUNT_ALLOCS is also defined, from now on
type objects will also appear in this list, provided at least one object
of a type has been allocated.
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.
variables to store internal data. As a result, any atempts to use the
unicode system with multiple active interpreters, or successive
interpreter executions, would fail.
Now that information is stored into members of the PyInterpreterState
structure.
* Adds missing pop() methods to weakref.py
* Expands test suite to broaden coverage of objects with
a mapping interface.

- Implement the behavior as specified in PEP 277, meaning os.listdir()
will only return unicode strings if it is _called_ with a unicode
argument.
- And then return only unicode, don't attempt to convert to ASCII.
- Don't switch on Py_FileSystemDefaultEncoding, but simply use the
default encoding if Py_FileSystemDefaultEncoding is NULL. This means
os.listdir() can now raise UnicodeDecodeError if the default encoding
can't represent the directory entry. (This seems better than silcencing
the error and fall back to a byte string.)
- Attempted to decribe the above in Doc/lib/libos.tex.
- Reworded the Misc/NEWS items to reflect the current situation.
This checkin also fixes bug #696261, which was due to os.listdir() not
using Py_FileSystemDefaultEncoding, like all file system calls are
supposed to.
introduced when shifting around some code, and added some redundancy
to reduce chances of hitting the wrong source code. (This is
experimental - it will improve the accuracy, but will reduce the
ability of the user to deliberately select the buffer they want the
buffer grubbing stuff to find. I think the accuracy improvement will
be worth it, but am not sure, so may remove this.)
[ 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!).
the reported path. (Eg, precompiled scripts with a file path suitable
for a different host, scripts actually running on a remote system or
with no valid path, like Zope through-the-web python scripts.)
On failing to find the code on the reported path, pdbtrack takes the
function name and looks through the buffers, from most to least
recent, seeking the first python-mode buffer that either is named for
the function or has a definition (def or class) for that function. So
to get source tracking for code that's not located where the path
indicates, you put a copy of the script in a buffer, and pdbtrack will
find it.
Also, fixed a small bug so pdbtrack now properly presents the overlay
arrow when you run the pdb 'w'here command.
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
