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.)
(from 10) and in main() (from 1).
Add a -v option that shows the raw times. Repeating it cranks up the
display precision.
Always use the "best of N" form of output.
- Make all local variables in the template start with an underscore,
to prevent name conflicts with the timed code.
- Added a method to print a traceback that shows source lines from the
expanded template.
- Use that method in main().

1. Clarify that rpc.SocketIO._getresponse() currently blocks on socket.
2. Improve exception handling in subprocess when GUI terminates abruptly.
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!
When the null string is used as the terminator, it used to be the same
as None, meaning "collect all the data". In the current code, however, it
falls into an endless loop; this change reverts to the old behavior.

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.
long header lines is now (properly) in the Header class. So we no
longer need _split_header() and we'll just defer to Header.encode()
when we have a plain string.
_encode_chunks(): Pass maxlinelen in instead of always using
self._maxlinelen, so we can adjust for shorter initial lines.
Pass this value through to _max_append().
encode(): Weave maxlinelen through to the _encode_chunks() call.
_split_ascii(): When recursively splitting a line on spaces
(i.e. lower level syntactic split), don't append the whole returned
string. Instead, split it on linejoiners and extend the lines up to
the last line (for proper packing). Calculate the linelen based on
the last element in the this list.
- 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.
part itself is longer than maxlen, and we aren't already splitting on
whitespace, then we recursively split the part on whitespace and
append that to the this list.
preserve spaces in the encoded/unencoded word boundaries. RFC 2047 is
ambiguous here, but most people expect the space to be preserved.
Really closes SF bug # 640110.
_split(): New implementation of ASCII line splitting which should do a
better job and not be subject to the various weird artifacts (bugs)
reported. This should also do a better job of higher-level syntactic
splits by trying first to split on semis, then commas, then
whitespace.
Use a Timbot-ly binary search for optimal non-ASCII split points for
better packing of header lines. This also lets us remove one
recursion call. Don't pass in firstline, but instead pass in the
actual line length we're shooting for. Also pass in the list of split
characters.
encode(): Pass in the list of split characters so applications can
have some control over what "higher level syntactic breaks" are.
Also,
decode_header(): Transform binascii.Errors which can occur when
decoding a base64 RFC 2047 header with bogus data, into an
email.Errors.HeaderParseError. Closes SF bug #696712.
_handle_multipart(): Ensure that if the preamble exists but does not
end in a newline, a newline is still added. Without this, the
boundary separator will end up on the preamble line, breaking the MIME
structure.
_make_boundary(): Handle differences in the decimal point character
based on the locale.
Charset: Alias __repr__ to __str__ for debugging.
header_encode(): When calling quopriMIME.header_encode(), set
maxlinelen=None so that the lower level function doesn't (also) try to
wrap/fold the line.
_max_append(): Change the comparison so that the new string is
concatenated if it's less than or equal to the max length.
header_encode(): Allow for maxlinelen == None to mean, don't do any
line splitting. This is because this module is mostly used by higher
level abstractions (Header.py) which already ensures line lengths. We
do this in a cheapo way by setting the max_encoding to some insanely
<100k wink> large number.
could be responsible for various unexplained problems with Python/OSA
interaction over the years):
- Enum values were passed as their string counterparts. Most applications
don't seem to mind this, but some do (InDesign).
- Attributes have never worked (!), as they were incorrectly passed
as parameters. Apparently nobody uses them much:-)

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

M run.py
Move exception formatting out of rpc.py. This allows each end of the
link to format and print exceptions how and where it sees fit and makes it
easier for threads to display their own exceptions.
* Changed variable name from 'list' to 'flist'.
* Replaced "while 1" with "while True".
* Replaced if/elif/elif/elif structure with a shorter and
faster dispatch dictionary that maps attrs to methods.
* Simplified and sped comparison logic by using
ifilter, ifilterfalse, and dict.fromkeys.
* Used True and False rather than 1 and 0.
* Replaced "while 1" with "while True"
* Rewrote read() and readline() for clarity and speed.
* Replaced variable 'list' with 'hlist'
* Used augmented assignment in two places.
specified with an absolute path, the object file is also
written to an absolute path. The patch drops the drive and
leading '/' from the source path, so a path like /path/to/foo.c
results in an object file like build/temp.i686linux/path/to/foo.o.
create a temporary file. This fixes#688011.
Got rid of the install() method in macresource, and replaced it with
a resource_filename() method which will optionally decode a given resourcefile
(which may be applesingle-encoded) and return the real resourcefile.
Use this new method in buildtools to copy the correct resource file to
the bundle. This fixes#688007.
- Replaced bootstrap shell script with Python script. This means
standalone apps built with bundlebuilder will not work on MacOS < 10.1,
since we depend (again) on an installed Python.
- Add a hack to set sys.executable; the bootstrap script does os.execve()
with an argv[0] that's different from the actual Python executable
(it has to match the CFBundleExecutable entry in the Info.plist to make
the app work both from the Finder and the command line, and it has to be
the bootstrap script), yet a proper sys.executable is needed to spawn
auxiliary processes.
