A newbie found it difficult to translate the exampe into a
case that used only short options or long options but not both.
He tried to shorten the tuple search but forgot the trailing comma,
The appropriate pattern is an equality check.
Revised the example to point him in the right direction.
Backport candidate.
tmpnam() appears essentially useless on Windows, and it finally broke
the test for Irmen de Jong. Read the long new comment in test_tmpnam()
for details. Since the MS implementation is insane, it might be good
if we supplied a different implementation.
Bugfix candidate.
- The socket module now provides the functions inet_pton and inet_ntop
for converting between string and packed representation of IP addresses.
See SF patch #658327.
This still needs a bit of work in the doc area, because it is not
available on all platforms (especially not on Windows).
docs here are best-guess: the MS docs I could find weren't clear, and
some even claimed _commit() has no effect on Win32 systems (which is
easily shown to be false just by trying it).

- section references: use a "tie" between the word "section" and the
section number, use quotation marks around section titles

interpreted by slicing, so negative values count from the end of the
list. This was the only place where such an interpretation was not
placed on a list index.
- Expose NullTranslations and GNUTranslations to __all__
- Set the default charset to iso-8859-1. It used to be None, which
would cause problems with .ugettext() if the file had no charset
parameter. Arguably, the po/mo file would be broken, but I still think
iso-8859-1 is a reasonable default.
- Add a "coerce" default argument to GNUTranslations's constructor. The
reason for this is that in Zope, we want all msgids and msgstrs to be
Unicode. For the latter, we could use .ugettext() but there isn't
currently a mechanism for Unicode-ifying msgids.
The plan then is that the charset parameter specifies the encoding for
both the msgids and msgstrs, and both are decoded to Unicode when read.
For example, we might encode po files with utf-8. I think the GNU
gettext tools don't care.
Since this could potentially break code [*] that wants to use the
encoded interface .gettext(), the constructor flag is added, defaulting
to False. Most code I suspect will want to set this to True and use
.ugettext().
- A few other minor changes from the Zope project, including asserting
that a zero-length msgid must have a Project-ID-Version header for it to
be counted as the metadata record.
* Doc - add doc for when functions were added
* UserString

'chars' is used for the last parameter everywhere.
These changes will be backported, since part of the changes
have already been made, but they were inconsistent.
out a month's worth of checkins to libstdtypes.tex (including my

I think this checkin merges them all back in, but if you make one of

Use \code{True} (or False) instead of true/false.

I've seen \constant{True} in other places.

some checking may be in order.
- 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.
[ 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!).
rarely needed, but can sometimes be useful to release objects

#693195.) Thanks to Kevin Jacobs!
* Modules/bz2module.c
(BZ2FileObject): Now the structure includes a pointer to a file object,
instead of "inheriting" one. Also, some members were copied from the
PyFileObject structure to avoid dealing with the internals of that
structure from outside fileobject.c.
(Util_GetLine,Util_DropReadAhead,Util_ReadAhead,Util_ReadAheadGetLineSkip,
BZ2File_write,BZ2File_writelines,BZ2File_init,BZ2File_dealloc,
BZ2Comp_dealloc,BZ2Decomp_dealloc):
These functions were adapted to the change above.
(BZ2File_seek,BZ2File_close): Use PyObject_CallMethod instead of
getting the function attribute locally.
(BZ2File_notsup): Removed, since it's not necessary anymore to overload
truncate(), and readinto() with dummy functions.
(BZ2File_methods): Added xreadlines() as an alias to BZ2File_getiter,
and removed truncate() and readinto().
(BZ2File_get_newlines,BZ2File_get_closed,BZ2File_get_mode,BZ2File_get_name,
BZ2File_getset):
Implemented getters for "newlines", "mode", and "name".
(BZ2File_members): Implemented "softspace" member.
(BZ2File_init): Reworked to create a file instance instead of initializing
itself as a file subclass. Also, pass "name" object untouched to the
file constructor, and use PyObject_CallFunction instead of building the
argument tuple locally.
(BZ2File_Type): Set tp_new to PyType_GenericNew, tp_members to
BZ2File_members, and tp_getset to BZ2File_getset.
(initbz2): Do not set BZ2File_Type.tp_base nor BZ2File_Type.tp_new.
* Doc/lib/libbz2.tex
Do not mention that BZ2File inherits from the file type.
* Removed the ifilter flag wart by splitting it into two simpler functions.
* Fixed comment tabbing in C code.
* Factored module start-up code into a loop.
Documentation:
* Re-wrote introduction.
* Addede examples for quantifiers.
* Simplified python equivalent for islice().
* Documented split of ifilter().
Sets.py:
* Replace old ifilter() usage with new.
__ne__ no longer complain if they don't know how to compare to the other
thing. If no meaningful way to compare is known, saying "not equal" is
sensible. This allows things like
if adatetime in some_sequence:
and
somedict[adatetime] = whatever
to work as expected even if some_sequence contains non-datetime objects,
or somedict non-datetime keys, because they only call __eq__.
It still complains (raises TypeError) for mixed-type comparisons in
contexts that require a total ordering, such as list.sort(), use as a
key in a BTree-based data structure, and cmp().
* Fixed typo in exception message for times()
* Filled in missing times_traverse()
* Document reasons that imap() did not adopt a None fill-in feature
* Document that count(sys.maxint) will wrap-around on overflow
* Add overflow test to islice()
* Check that starmap()'s argument returns a tuple
* Verify that imap()'s tuple re-use is safe
* Make a similar tuple re-use (with safety check) for izip()
This patch adds stdin, stdout as optional arguments to the cmd.Cmd
constructor (defaulting to sys.stdin, sys.stdout), and changes the Cmd
methods throughout to use self.stdout.write() and self.stdin.foo for
output and input. This allows much greater flexibility for using cmd -
for instance, hooking it into a telnet server.
Patch for library module and for documentation.
error handers in the Unicode codecs: Negative
positions are treated as being relative to the end of
the input and out of bounds positions result in an
IndexError.
Also update the PEP and include an explanation of
this in the documentation for codecs.register_error.
Fixes a small bug in iconv_codecs: if the position
from the callback is negative *add* it to the size
instead of substracting it.
From SF patch #677429.
* remove doc for defunct IllegalKeywordArgument exception
* add note that HTTP class is for backward compatibility and refer reader to
online docstrings for help
compare against "the other" argument, we raise TypeError,
in order to prevent comparison from falling back to the
default (and worse than useless, in this case) comparison
by object address.
That's fine so far as it goes, but leaves no way for
another date/datetime object to make itself comparable
to our objects. For example, it leaves Marc-Andre no way
to teach mxDateTime dates how to compare against Python
dates.
Discussion on Python-Dev raised a number of impractical
ideas, and the simple one implemented here: when we don't
know how to compare against "the other" argument, we raise
TypeError *unless* the other object has a timetuple attr.
In that case, we return NotImplemented instead, and Python
will give the other object a shot at handling the
comparison then.
Note that comparisons of time and timedelta objects still
suffer the original problem, though.
