New submission from Vikram U Shenoy <vikram.u.shenoy at gmail.com>:
Attached are two patches:
* Update PEP 4 about 'new' module which is deprecated since python 2.6
in favour of using types module.
* Update documentation for 'new' module.
Not sure about the exact date of proposal for deprecating 'new' module,
but closest that I was able to find was this python-dev mail thread
after it had been removed from py3k branch:

New submission from Cournapeau David <david at ar.media.kyoto-u.ac.jp>:
On windows, with python 2.6, s = '%s' % float('inf') is 'inf', but s =
'%f' % float('inf') is equal to '1.#INF'.
This patch fixes the inconsistency, by using the code from floatobject.f
format_float into stringobject.c formatfloat. I think it would be better
to use the same underlying implementations for both functions, but it is
not so easy, because format_float cannot fail (return void), whereas
formatfloat can (return error code).

New submission from Kandalintsev Alexandre <bug_hunter at messir.net>:
Documentation says that
========
There?s no chance that the reference count can overflow; at least as many bits
are used to hold the reference count as there are distinct memory locations in
virtual memory (assuming sizeof(Py_ssize_t) >= sizeof(void*)). Thus, the
reference count increment is a simple operation.
========
But Py_ssize_t is a signed type so in case of sizeof(Py_ssize_t) == sizeof
(void*)) it can only reference a half of memmory :). But because any python
object consumes much more than 2bytes this is not a problem.

Message-ID: <1230869380.06.0.720418986656.issue4804@psf.upfronthosting.co.za>
New submission from Mark Hammond <mhammond at users.sourceforge.net>:
This block in exceptions.c:
#if defined _MSC_VER && _MSC_VER >= 1400 && defined(__STDC_SECURE_LIB__)
...
/* turn off assertions in debug mode */
prevCrtReportMode = _CrtSetReportMode(_CRT_ASSERT, 0);
#endif
Does exactly what the comment says it does - disables all assertions.
It disables *all* CRT assertions in the process, which includes some
very useful ones related to memory corruption, and all 'assert' and
'ASSERT' statements in all Python extension modules.
The change was introduced in:
"""
r46894 | kristjan.jonsson | 2006-06-13 01:45:12 +1000 (Tue, 13 Jun 2006)
| 2 lines
Fix the CRT argument error handling for VisualStudio .NET 2005. Install
a CRT error handler and disable the assertion for debug builds. This
causes CRT to set errno to EINVAL.
This update fixes crash cases in the test suite where the default CRT
error handler would cause process exit.
"""
which seems like a very large hammer to be using (ie, the problem
causing the assertions to blow should probably have been fixed). I'd
like to remove these 2 lines. Any objections, or should I upload the
trivial patch?

Subject: [New-bugs-announce] [issue4805] Make python code compilable with a
C++ compiler
In-Reply-To: <1230872206.73.0.47638283248.issue4805@psf.upfronthosting.co.za>
Message-ID: <1230872206.73.0.47638283248.issue4805@psf.upfronthosting.co.za>
New submission from Alexander Belopolsky <belopolsky at users.sourceforge.net>:
I am posting this patch mainly to support python-dev discussion on this
topic. In the past (see r45330) it was possible to compile python core
and standard library modules using a C++ compiler.
According to Martin v. L?wis (issue4665), "It's not a requirement that
the Python source code is compilable as C++. Only the header files
should be thus compilable." However, I can see certain benefits from
such requirement:
1. It is hard to verify that header files are compilable if source code
is not. With compilable source code, CC=g++ ./configure; make will
supply an adequate test that does not require anything beyond a standard
distribution.
2. Arguably, C++ compliant code is more consistent and less error prone.
For example, "new" is a really bad choice for a variable name regardless
of being a C++ keyword, especially when used instead of prevailing "res"
for a result of a function producing a PyObject. Even clearly redundant
explicit casts of malloc return values arguably improve readability by
reminding the type of the object that is being allocated.
3. Compiling with C++ may reveal actual coding errors that otherwise go unnoticed. For example, use of undefined PyLong_BASE_TWODIGITS_TYPE in Objects/longobject.c.
4. Stricter type checking may promote use of specific types instead of
void* which in turn may help optimizing compilers.
5. Once achieved, C++ compilability is not that hard to maintain, but
restoring it with patches like this one is hard because it requires
review of changes to many unrelated files.

Message-ID: <1230900364.95.0.0532833034138.issue4806@psf.upfronthosting.co.za>
New submission from Hagen F?rstenau <hfuerstenau at gmx.net>:
If we call some function f with a generator as star argument and this
generator raises a TypeError, we get the following exception:
>>> def f(x): pass
...
>>> def broken(): raise TypeError
...
>>> f(*(broken() for x in (0,)))
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: f() argument after * must be a sequence, not generator
This is a misleading error message, as it's usually no problem to use a
generator as a star argument. Even just replacing the TypeError by some
other exception leads to the expected result, i.e. the exception gets
correctly propagated.
The problem seems to be around line 3710 of Python/ceval.c where the
generator is converted to a tuple. If this conversion raises a
TypeError, then the error message is replaced, which will mask any
TypeError raised by the generator.
I'm not sure how to solve this. We probably can't distinguish a "good"
TypeError from a "bad" TypeError at this point, so we might have to make
a special case for the conversion of generators.

New submission from Ulrich Eckhardt <eckhardt at satorlaser.com>:
Note up front: there is a win32 function wsprintf() and an ISO C
function swprintf(), these are different things in case you wonder.
In _winreg.c, there are two functions that use wsprintf on a char
buffer, while the function takes a TCHAR buffer instead. This leads to
compile warning and runtime errors when _UNICODE is defined, like e.g.
under MS Windows CE. The attached patch replaces the two calls to that
function with calls to fprintf() and PyString_FromFormat().

New submission from Raymond Hettinger <rhettinger at users.sourceforge.net>:
In r59144 , a bunch of internal-use constants were dumped in the main
namespace. These all need to be prefixed with an underscore.
They should be fixed right-away before people start using them. Since
they are externally undocumented and since the internal notes describe
them as being only for internal-use, I think this can go in as a bugfix.

New submission from Mitchell Model <mlm at acm.org>:
In function detect_tkinter_darwin of setup.py framework_dirs should be
the reverse of what it is: first the user's library should be searched,
then /Library, and finally /System/Library. If Tk 8.5 is installed in
/Library or ~/Library make will otherwise find the headers from 8.4 but
the libraries from 8.5.
Issue 4017 discusses this problem, among others, and is marked fixed,
but it is still incorrect in the 2.6 and 3.0 downloads as well as in the
trunk, 3.0, and 3.1 subversion repositories. It may have been "fixed"
in so far as someone was able to make a .dmg by manually altering
setup.py, and that's great, but it isn't fixed in the source and the
problem will reappear with each new version.

When using the optional ftplib.FTP()'s timeout parameter which
specifies a timeout in seconds for blocking operations like the
connection attempt, it is applied on both FTP control and passive data
channel (if any).
It is not applied for active (PORT/EPRT) data connections.

permutations} for empty combinations

New submission from Thomas Finley <tfinley at gmail.com>:
This is a patch for the Python 3.1 build checked out from
http://svn.python.org/projects/python/branches/py3k
The current behavior of itertools.combinations(iterable,r) and
itertools.permutations(iterable,r) is to throw a ValueError if iterable
yields fewer than r items. This changes these functions so the
generator instead yields 0 items.
As for my argument for acceptance, while the original behavior is not a
bug insofar as its implementation was deliberate, I'd argue this is
undesirable on grounds of mathematical consistency and functionality.
In mathematics the "choose" function is defined as "(n choose r)=0" for
r>n, so itertools.combinations' behavior is inconsistent with its
obvious combinatorial analogy. (Similar for permutations and the
combinatorial "P" function.)
For functionality I'll cite my own case as anecdote. In writing
regression tests I wanted to ensure that a group of items obeyed a
certain "mutually consistent" property between all triples. (Something
akin to the triangle inequality.) So:
all(triangle_respected(*triple) for triple in
itertools.combinations(group, 3))
If len(group)<=2, that's fine, since with no triangles there is no
inconsistency, and all(())==True. However, the code failed with a
ValueError when groups were that small. Working around this was fairly
awkward, since I wanted to continue to fail noisily if my
triangle_respected function threw a ValueError, and I wasn't sure at all
that it wouldn't if my items were
The patch modifies Modules/itertoolsmodule.c slightly, changing
combinationsobject_new and permutationsobject_new. (Deleting the error
throwing code, and have one line changes in both structures to handle
the n>r case. One could handle this special case more efficiently than
I do by not bothering to allocate certain structures in this case, but I
didn't want to tempt fate.) The patch also changes the appropriate
tests in Lib/test/test_itertools.py .
Obviously, this would break code that depends upon Python throwing
ValueError in the event of the combination or permutation sequence being
empty. However, I hope given that combinations and permutations are a
relative novelty that their behavior in this corner case is not yet
etched in stone.
Sorry if this belongs in a PEP -- it seems quite minor, but I don't
quite have a feel what the threshold is.

Here is another patch, this time for the fallback-md5-module. I know
that situations are rare where openssl is not present but threading is.
However they might occur out there and the md5module needed some love
anyway:
- The MD5 class from the fallback module can now also use threads with
'small locks'
- The behaviour regarding unicode data input is now consistent as to
what the openssl-driven classes do.
- Some code cleanup.
I might act on the sha modules as way the next days. sha256.c still
accepts 's#'...

Misc/cheatsheet could do with an upgrade, both for the 2.x and 3.x branches.
For 3.x, I guess the changes needed are quite extensive. I'm not sure
how much needs to be changed or added for 2.x; at a quick
glance, the 'with' statement, the 'x if b else y' construction, and the
unified try-except-finally are missing.

Here is the follow-up to issue #4818. The patches attached allow the

Also the build-in SHA modules will now no longer accept "s#" as input.
Input is parsed just as in the openssl-driven classes where
unicode-objects are explicitly rejected.
The built-in hash modules have been not quite beautiful before even more
code is now copy & pasted between them. Is there any interest in
refactoring all those modules? AFAIK _sha1 and such are only used by
hashlib.py ...

confusing
In-Reply-To: <1231051843.8.0.720726802561.issue4827@psf.upfronthosting.co.za>
Message-ID: <1231051843.8.0.720726802561.issue4827@psf.upfronthosting.co.za>
New submission from Jason Kankiewicz <jkankiewicz at acm.org>:
"Callback example 1: trivial callback" reads
Here?s an example of a callback option that takes no arguments, and
simply records that the option was seen:
def record_foo_seen(option, opt_str, value, parser):
parser.saw_foo = True
parser.add_option("--foo", action="callback",
callback=record_foo_seen)
but the following paragraph
Of course, you could do that with the store_true action.
is wrong because
parser.add_option("--foo", action="store_true", dest="saw_foo")
would actually be duplicated by
def record_foo_seen(option, opt_str, value, parser):
parser.values.saw_foo = True
parser.add_option("--foo", action="callback",
callback=record_foo_seen)
For example:
>>> from optparse import OptionParser
>>> parser = OptionParser()
>>> def record_foo_seen(option, opt_str, value, parser):
... parser.saw_foo = True
...
>>> parser.add_option("--foo", action="callback", callback=record_foo_seen)
<Option at 0xab4f58: --foo>
>>> parser.parse_args(['--foo'])
(<Values at 0xabb0f8: {}>, [])
>>> parser = OptionParser()
>>> parser.add_option("--foo", action="store_true", dest="saw_foo")
<Option at 0xabb1e8: --foo>
>>> parser.parse_args(['--foo'])
(<Values at 0xabb1c0: {'saw_foo': True}>, [])
>>> parser = OptionParser()
>>> def record_foo_seen(option, opt_str, value, parser):
... parser.values.saw_foo = True
...
>>> parser.add_option("--foo", action="callback", callback=record_foo_seen)
<Option at 0xabb508: --foo>
>>> parser.parse_args(['--foo'])
(<Values at 0xabb3f0: {'saw_foo': True}>, [])

New submission from Ulrich Eckhardt <eckhardt at satorlaser.com>:
Specifying the '+' more than once while opening a file results in the
error "Must have exactly one of read/write/append mode". The attached
patch extends that with ".. and at most one optional plus".
Further, the patch checks these after the loop that parses the mode
string, avoiding some unnecessary gotos and saving a few lines of code
overall.

Message-ID: <1231080757.34.0.371299910719.issue4831@psf.upfronthosting.co.za>
New submission from David M. Beazley <beazley at users.sourceforge.net>:
Please forgive me, but I'm really trying to wrap my brain around the
behavior of exec() in Python 3. Here's a quote from the documentation:
"In all cases, if the optional parts are omitted, the code is
executed in the current scope."
This is referring to the optional use of the globals/locals parameters
and seems to indicate that if they're omitted the code executes in the
scope where the exec() appeared.
Yet, this code fails:
def foo():
exec("a = 42")
print(a) # NameError: a
Now, I realize that exec() became a function in Python 3. However,
regardless of that, is it really the intent that exec() not be allowed
to ever modify any local variable of a function? In other words, do I
really have to do this?
def foo():
ldict = locals()
exec("a=42",globals(),ldict)
a = ldict['a']
print(a)
I submitted a bug report about this once before and it was immediately
dismissed.
I would appreciate some greater clarity on this matter this go around.
Specifically, what is the approved way to have exec() modify the local
environment of a function?

There should not be necessity to write filename *with extension* at the
saving dialog. It should be enough, at least on Windows, to put there
just "hello" and get "hello.py". It is really complication especially
for beginners. If they, as they are used to from another programs, put
there just "hello", it is saved without extension ".py" what have 2
result: they cannot see any icons at that file and they are not able to
run in, cause python.exe is bind with ".py".
Hoping its not duplicate I haven't found anything like this here.

Message-ID: <1231088968.72.0.101458538333.issue4833@psf.upfronthosting.co.za>
New submission from Robert Schuppenies <robert.schuppenies at gmail.com>:
We have an issue with the Python cheeseshop which is probably an issue
with Python itself as well.
When we create a zip file with standard linux tools ('zip os-zipped.zip
*'), uploading it works fine. But if we use the zipfile module from
Python and try to upload the result to the cheeseshop, we get this error
message:
" Error unpacking zipfile:[Errno 2] No such file or directory:
u'/data/packagedocs/Pympler/_sources/index.txt'"
Turns out that the Python-zipped version does not include explicit
directories. The OS-zipped version contains "directory/,
directory/asizeof.txt", the Python-zipped file only
"directory/asizeof.txt". Digging deeper, Python has no way to explicitly
add directories to a zip file.
It would be useful to have an option which allows the explicit creation
of directories inside of zip files. This would help when working with
applications which do not create directories if they are not explicitly
specified.

OS X 10.5

Message-ID: <18784.64250.252843.484595@montanaro.dyndns.org>
New submission from Skip Montanaro <skip at pobox.com>:
I get this error when trying to configure with Intel's icc on my Mac (Intel,
10.5.6, Xcode 3.1.2):
>> configure:10332: checking size of size_t
>> configure:10637: icc -o conftest -g -O2 conftest.c >&5
>> ld: library not found for -lgcc_s
After a couple notes to python-dev and a little bit of sleuthing with -v I
discovered that it was generating -lgcc_s instead of -lgcc_s.10.5 in the ld
line. I narrowed the problem down to this code in configure.in:
# Calculate the right deployment target for this build.
#
cur_target=`sw_vers -productVersion | sed 's/\(10\.[[0-9]]*\).*/\1/'`
if test ${cur_target} '>' 10.2; then
cur_target=10.3
fi
if test "${UNIVERSAL_ARCHS}" = "all"; then
# Ensure that the default platform for a 4-way
# universal build is OSX 10.5, that's the first
# OS release where 4-way builds make sense.
cur_target='10.5'
fi
CONFIGURE_MACOSX_DEPLOYMENT_TARGET=${MACOSX_DEPLOYMENT_TARGET-${cur_target}}
# Make sure that MACOSX_DEPLOYMENT_TARGET is set in the
# environment with a value that is the same as what we'll use
# in the Makefile to ensure that we'll get the same compiler
# environment during configure and build time.
MACOSX_DEPLOYMENT_TARGET="$CONFIGURE_MACOSX_DEPLOYMENT_TARGET"
export MACOSX_DEPLOYMENT_TARGET
EXPORT_MACOSX_DEPLOYMENT_TARGET=''
The test of cur_target against 10.2 seems suspicious. This code dates from
r65061 (checked in by Benjamin last July) which states:
#3381 fix framework builds on 10.4
Maybe it should be
if test ${cur_target} '>' 10.2 -a ${cur_target} '<' 10.5 ; then
cur_target=10.3
fi
(which works).

New submission from Ulrich Eckhardt <eckhardt at satorlaser.com>:
In _fileio.c, there is the following comment: "Returns 0 on success,
errno (which is < 0) on failure." The problem here is the claim that
errno ever was less than zero, which is simply wrong.
You can see this being a problem with the following few lines:
import os, io
fd = os.open( "some existing file", os.O_RDONLY)
s1 = os.fdopen(fd)
s2 = io.open(fd)
os.close(fd)
s1.close()
s2.close()
The call to close() pulls the file from under the feet of the two stream
objects, but only the one opened with os.fdopen() actually detects that.
For the second one, errno is set, but to a positive value which isn't
detected correctly.

I have a concern about distutils.dir_util and distutils.file_util modules.
Distutils implements its own file and directory copy functions there, that
could be replaced by shutil ones, except four small features:
- verbose : each time a file is copied a "source -> target" is displayed
in the output.
- dry_run : nothing is really copied
- update : each file will only be copied if they don't exist in the
target path or if they are newer
- the copy_tree function returns the list of files copied (or that
should have been copied when dry_run is True).
I think shutil could benefit from these small features, and
distutils code could be refactored to use them.
Here's a small proposal for distutils.copytree::
copytree(src, dst, symlinks=False, ignore=None) -> None
becomes:
copytree(src, dst, symlinks=False, ignore=None, update=False,
verbose=False, dry_run=False, logger=None) -> list of
copied files
where:
- update
- if False, copytree behaves as usual: if os.path.samefile(source,
target) is True it raise an error
- if True, the file is copied only if it's newer or doesn't exists,
otherwise it doesn't raise
- logger
- if None, logger is set to logging.info
- verbose: if True, a logger.info("source -> target") call is made on
each copy
- dry_run: if True, the files are not really copied
Last, the function returns a tuple of copied files.
>From there, distutils can work with shutil.copytree, shutil.copyfile and
shutil.copy2
Pro's:
- distutils can rely on this function and its specialized modules dissapear
- shutil.copytree becomes more powerful
- less redundancy in the sdtlib
Con's:
- the API signature is getting a bit complex
- distutils use case might not be common enough

Message-ID: <1231171240.01.0.534546346997.issue4845@psf.upfronthosting.co.za>
New submission from Jean-Paul Calderone <exarkun at divmod.com>:
Here's a transcript demonstrating the disagreement:
exarkun at charm:~$ mkdir warningexample
exarkun at charm:~$ cd warningexample/
exarkun at charm:~/warningexample$ mkdir foo
exarkun at charm:~/warningexample$ touch foo/__init__.py
exarkun at charm:~/warningexample$ cat > foo/bar.py
import warnings
def foo():
warnings.warn("foo")
exarkun at charm:~/warningexample$ python -c 'import foo.bar'
exarkun at charm:~/warningexample$ mv foo bar
exarkun at charm:~/warningexample$ python -c 'import bar.bar; bar.bar.foo()'
bar/bar.py:3: UserWarning: foo
warnings.warn("foo")
exarkun at charm:~/warningexample$ python -c 'import bar.bar, inspect;
print inspect.getabsfile(bar.bar.foo)'
/home/exarkun/warningexample/foo/bar.py
exarkun at charm:~/warningexample$
Notice that the warning is emitted for the file bar/bar.py but the
inspect module claims that the function which emitted the warning is
defined in /home/exarkun/warningexample/foo/bar.py. It seems that the
warning system has somehow noticed that the .pyc file has the wrong
source file listed and has figured out the correct file name, whereas
the inspect module is blindly following the contents of the .pyc file.
It would be great if the inspect module were at least as good at
figuring out filenames as the warnings system.

The build script for a Mac OS installer, in
Mac/BuildScript/build-installer.py, currently requires OS 10.4 and
Python 2.3. At some point it will have to be ported to a newer version
of Python (and Mac OS). It uses a number of modules which are slated
for future removal, particularly Carbon and MacOS. These modules are
only used in the function "setIcon". They can be replaced with a call
to a Cocoa method via PyObjC. The "setIcon" function using PyObjC would
look like this:
def setIcon(folder, imagefile):
try:
import os, AppKit
AppKit.NSApplicationLoad() # initialize Cocoa
return
AppKit.NSWorkspace.sharedWorkspace().setIcon_forFile_options_(
AppKit.NSImage.alloc().initWithContentsOfFile_(imagefile),
os.path.abspath(folder), 0)

In order to create an element with an attribute and a child, this is
necessary:
e = Element("foo")
e.setAttribute("bar", "baz")
e.appendChild(quux)
It would be preferable if Element.__init__ accepted two additional
parameters to shorten this:
e = Element("foo", attributes={"bar": "baz"}, children=[quux])
It may also be preferable to have a third new parameter, attributesNS,
to parallel the Element.setAttributeNS method. This would accept a dict
mapping namespaceURI and qualifiedName to an attribute value.

symbol is defined in the same file.
- PyThread__PyThread_exit_thread appears in the .h but is not defined

PyThread__exit_thread but it is not exposed anywhere (since r12178...)
Better remove unused code...

New submission from STINNER Victor <victor.stinner at haypocalc.com>:
I don't like the current behaviour of Python on closed socket:
>>> import socket
>>> s=socket.socket(socket.AF_INET, socket.SOCK_STREAM)
>>> s.close()
>>> s.fileno()
-1
>>> s.getsockname()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
socket.error: [Errno 9] Bad file descriptor
Some operations are still allowed whereas the other raise an ugly
error message. Most (or all) operation on a closed socket should be
blocked by a socket.error.
My patch raises a socket.error("I/O operation on closed socket") for
most operations except:
- close(): it call be called twice (or more) (keep current behaviour)
- gettimeout(): should we raise an error?
- setblocking(), settimeout(): should we raise an error? Maybe yes
for setter but no for getter which would be inconsistent with
getpeername()...
The io library already has this behaviour: read(), write(), flush(),
etc. are blocked by a ValueError("I/O operation on closed file") (see
IOBase._check_closed in the io library).
Issue #4791 changes the behaviour of closed SocketIO object: fileno()
method raise a socket.error if it's closed even if the socket is still
open.

There are several checks like "GetVersion() < 0x80000000" that try to
determine whether there is support for the WCHAR versions of the win32
API. Since all support for MS Windows 95, 98 and ME has been dropped,
all supported systems support those APIs. Also, I need that cleanup as
preparation for porting Python to MS Windows CE, so that I don't have
to clone/port code for obsolete systems there. I'll be providing
patches here.

New submission from Lukas Lueg <knabberknusperhaus at yahoo.de>:
MD5 is one of the most popular cryptographic hash-functions around,
mainly for it's good performance and availability throughout
applications and libraries. The MD5 algorithm is currently implemented
in python as part of the hashlib-module and (in more general terms) as
part of SSL in the ssl-module. However, concerns about the security of
MD5 have risen during the last few years. In 2007 a practical attack to
create collisions in the compression-function has been released and on
12/31/2008 US-CERT issued a note to warn about the general insecurity of
MD5 (http://www.kb.cert.org/vuls/id/836068).
I propose and strongly suggest to start deprecate direct support for MD5
during this year and completly remove support for it afterwards.
* MD5 is a cryptographic hash function, it's reason for being is
security. By means of current hardware and attack vectors it's a matter
of hours to create collisions and fool MD5 hashes. The reason for being
has come to an end.
* Python runs an uncountable number of exposed user interfaces on the
web. Usually the programmers rely on the security of the backing
libraries. Python can't provide this with MD5.
* The functionality of MD5 can be easily replaced by using other hashes
that are supported by python (e.g. SHA1). They supply compareable
performance but are not binary-compatible (yay).
* Programmers use MD5 in python without the need for it's cryptographic
attributes (e.g. creating unique indexes). Keeping MD5 for this use
however devaluates overall security of python for the good of few.
I'd like to start a discussion about this. Please keep in mind that -
although MD5 is currently still very popular and python's support for it
is justifed by demand - it's existence will come to an end soon.
We should now act and give people time to update their implementations.
In a rough cut:
- Patch haslib to throw a DeprecationWarning, starting during the first
half of 2009.
- Update documentation not to use MD5 for security reasons
- Remove MD5 from python in 2010.
- Keep accordance to PEP 4
Goodbye MD5 and thanks for all the fish.

Subject: [New-bugs-announce] [issue4859] pwd, spwd,
grp functions vulnerable to denial of service
In-Reply-To: <1231275151.13.0.805176401894.issue4859@psf.upfronthosting.co.za>
Message-ID: <1231275151.13.0.805176401894.issue4859@psf.upfronthosting.co.za>
New submission from David Watson <baikie at users.sourceforge.net>:
The pwd (and spwd and grp) modules deal with data from
/etc/passwd (and/or other sources) that can be supplied by users
on the system. Specifically, users can often change the data in
their GECOS fields without the OS requiring that it conform to a
specific encoding, and given some automated account signup
system, it's conceivable that arbitrary data could even be placed
in the username field.
This causes a problem since the functions in these modules try to
decode the data into str objects, and if a user has placed data
in /etc/passwd, say, that does not conform to the relevant
encoding, the function will raise UnicodeDecodeError and thus
prevent the program from learning the relevant mapping between
username and UID, etc. (or crash the program if it wasn't
expecting this). For a system program written in Python, this
can amount to a denial of service attack, especially if the
program uses the get*all() functions.
Currently, the pwd module tries to decode the string fields using
the Unicode-escape codec, i.e. like a Python string literal, and
this can fail when given an invalid backslash escape. You can
see this by running chfn(1), entering something like "\ux" in one
of the fields, and then calling pwd.getpwnam(yourname) or
pwd.getpwall(). Perhaps the use of this codec is a mistake,
given that spwd and grp decode the string fields as UTF-8, but
chfn could also be used to enter non-UTF-8 data in the GECOS
field. You can see similar failures in the grp and spwd modules
after adding a user with a non-UTF-8 name (do something like
"useradd $'\xff'" in bash).
A debug build of Python also reports a reference counting error
in grp (count goes to -1) when its functions fail on non-UTF-8
data; what I think is going on is that in mkgrent(),
PyStructSequence_SET_ITEM steals the reference to "w", meaning
the second "Py_DECREF(w)" shouldn't be there. Also, getpwall()
and getgrall() leave file descriptors open when they fail, since
they don't call end*ent() in this case. The attached minor.diff
fixes both of these problems, I think.
I've also written a patch (bytes.diff, attached) that would add
new functions pwd.getpwnamb(), etc. (analogous to os.getcwdb())
to return bytes objects for the text fields, thus avoiding these
problems - what do you think? The patch also makes pwd's
original string functions use UTF-8 like the other modules.
Alternatively or in addition, a quick "fix" for the GECOS problem
might be for the pwd module to decode the text fields as Latin-1,
since in the absence of backslash escapes this is what the
Unicode-escape encoding is equivalent to. This would at least
block any DoS attempts using the GECOS field (or attempts to add
extra commas with \x2c, etc.) without changing the behaviour
much. The attached latin1.diff does this.

New submission from Noufal <noufal at nibrahim.net.in>:
If a cookie is created with a " character in the content, the js_output
which is emitted is bad javascript. eg.
>>> import Cookie
>>> c=Cookie.Cookie('Customer="WILE_E_COYOTE"; Version=1; Path=/acme')
>>> print c
Set-Cookie: Customer="WILE_E_COYOTE"; Path=/acme; Version=1
>>> print c.js_output()
<script type="text/javascript">
<!-- begin hiding
document.cookie = "Customer="WILE_E_COYOTE"; Path=/acme; Version=1";
// end hiding -->
</script>
>>>
Also, the test_cookie tests (test_load) explicitly checks for this
(wrong) output.
I have attached a patch that seems to fix this or at the very least
produces the same Cookie settings whether the cookie is set using the
header or using javascript (I've verified this on firefox on Linux).

New submission from Matthias Klose <doko at debian.org>:
there are some problems with ctypes.util.find_library(), which I would
like to see fixed on active branches.
- find_library is not robust, if either objdump or gcc are not
installed. fixed by raising an exception if the tools are not
found. Is OSError the correct type for this exception?
- ldconfig -p already prints the shared object name. afaics there
is no need to call objdump again.
- the regexp to scan the ldconfig -p output is wrong for
architectures where libraries of more than one abi type are
installed, e.g. having ix86 libs on a x86_64 system. Having
only the library installed which doesn't match the python
executable lets find_library find the wrong library. Note that
the patch is only correct under the assumption that the python
executable is unstalled for the "main" abi.
patch attached, ok to check in?

New submission from Amaury Forgeot d'Arc <amauryfa at gmail.com>:
First write a utf-16 file with its signature:
>>> f1 = open('utf16.txt', 'w', encoding='utf-16')
>>> f1.write('0123456789')
>>> f1.close()
Then read it twice:
>>> f2 = open('utf16.txt', 'r', encoding='utf-16')
>>> print('read1', ascii(f2.read()))
read1 '0123456789'
>>> f2.seek(0)
0
>>> print('read2', ascii(f2.read()))
read2 '\ufeff0123456789'
The second read returns the BOM!
This is because the zero in seek(0) is a "cookie" which contains both the position
and the decoder state. Unfortunately, state=0 means 'endianness has been determined:
native order'.
maybe a suggestion: handle seek(0) as a special value which calls decoder.reset().
The patch implement this idea.

New submission from Skip Montanaro <skip at pobox.com>:
I was just poking around the distutils documentation and came across the
distutils.mwerkscompiler module. Surely that can't be useful anymore, can
it? The doc reads, in its entirety:
Contains MWerksCompiler, an implementation of the abstract CCompiler
class for MetroWerks CodeWarrior on the pre-Mac OS X Macintosh. Needs
work to support CW on Windows or Mac OS X.
So the only place it used to work was on pre-Mac OS X, which Python doesn't
support any longer and "will need work" for Windows or Mac OS X which
presumably nobody has done. This module should be deprecated in 3.1 and
removed in 3.2.

I think you misunderstand the kind of problem that has been detected.
It is still *not* possible to produce a colliding text within
reasonable, when given the md5 hash. So when md5 is used as the trap
function for password storage, it's use remains perfectly safe.
Likewise, md5 is still well capable of detecting corruption of binary
files (e.g. during downloads), and will remain in use for this
application for many more years.
It is only in the context of digital signatures that the "chosen prefix"
attack can be demonstrated successfully.

That's like saying "Mercedes drivers rely on efficient operation of the
motor. By putting water into the tank, the motor fails to deliver. So
let's put a ban on the usage of water in cars."
> * The functionality of MD5 can be easily replaced by using other hashes

In some case, yes, replacement is easy. In other cases, replacement is
not so easy. For example, for password hashes, you cannot simply rehash
all passwords - because you typically don't know what they are.

New submission from Karsten Petersen <kapet at kapet.de>:
[Guido asked me to file this as an issue.]
On Mac OS X Apple has configured the system provided Python to also
search this global site-packages directory:
/Library/Python/<version>/site-packages/
This allows users to install their own system-wide packages there (and
not have them to drop into /System/Library/Frameworks/Python....../).
Unfortunately if you install Python from python.org (or pythonmac.org)
it is not searching this path, it only searches the site-packages
directory _within_ its own framework:
/Library/Frameworks/Python...../
That directory is of course not searched by the Apple provided Python.
This is an issue for addon package installers (think PIL or numpy):
There is no single path that will be found by both the system provided
Python and a Python installed from python.org. This makes most/all (?)
of the pre-built packages on pythonmac.org unusable with the version of
Python Apple ships although there is no version conflict or such - it
simply installs stuff in the "wrong" directories.
Many people who tried to install PIL for Django or App Engine stumbled
into this. The system provided Python version was fine. But compiling
PIL is hard. So they installed PIL from pythonmac.org. That couldn't
be found by Python. Now some people manually copied stuff around, some
created symlinks, some installed a second Python 2.5. (The lucky ones
picked a Python download from python.org, the not so lucky ones
installed the 2.5.0 release from pythonmac.org...)
I've attached a diff of a stock Python 2.5.1 library against what I
found on my Apple Mac OS X 10.5 (Leopard) system. I've dropped changes
that are not related to the path.

In python 3.0, it crashes in _CallProc (callproc.c, line 1136) :
if (atypes[i]->type == FFI_TYPE_STRUCT
atypes[i] == NULL here because when there is no argtypes, the default
converter (ConvParam) does not set ffi_type for string parameters if
HAVE_USABLE_WCHAR_T is FALSE.
To make it work, I have to define the argtypes for the function :
>>> import ctypes
>>> lib=ctypes.cdll['./libtcod.so']
>>> from ctypes import *
>>> lib.TCOD_console_init_root.argtypes=[c_int,c_int,c_char_p,c_uint]

I've compiled python 3.0 on a standard Ubuntu 8.04 and the test_ctypes

Subject: [New-bugs-announce] [issue4868] Faster utf-8 decoding
In-Reply-To: <1231341903.79.0.54860955311.issue4868@psf.upfronthosting.co.za>
Message-ID: <1231341903.79.0.54860955311.issue4868@psf.upfronthosting.co.za>
New submission from Antoine Pitrou <pitrou at free.fr>:
Here is a patch to speedup utf8 decoding. On a 64-bit build, the maximum
speedup is around 30%, and on a 32-bit build around 15%. (*)
The patch may look disturbingly trivial, and I haven't studied the
assembler output, but I think it is explained by the fact that having a
separate loop counter breaks the register dependencies (when the 's'
pointer was incremented, other operations had to wait for the
incrementation to be committed).
[side note: utf8 encoding is still much faster than decoding, but it may
be because it allocates a smaller object, regardless of the iteration count]
The same principle can probably be applied to the other decoding
functions in unicodeobject.c, but first I wanted to know whether the
principle is ok to apply. Marc-Andr?, what is your take?
(*) the benchmark I used is:
./python -m timeit -s "import
codecs;c=codecs.utf_8_decode;s=b'abcde'*1000" "c(s)"
More complex input also gets a speedup, albeit a smaller one (~10%):
./python -m timeit -s "import
codecs;c=codecs.utf_8_decode;s=b'\xc3\xa9\xe7\xb4\xa2'*1000" "c(s)"

When investigating issue #4859 I found that when pwd.getpwall()
and grp.getgrall() fail due to decoding errors, they leave open
file descriptors referring to the passwd and group files, since
they don't call the end*ent() functions in this case. Also, the
grp.* functions have a reference counting error when they fail in
this way - a debug build reports that an object's reference count
goes to -1. What I think happens is that in mkgrent(),
PyStructSequence_SET_ITEM steals the reference to "w", meaning
that the "Py_DECREF(w)" call shouldn't be made afterwards. The
attached diff fixes both of these problems, I think, and applies
to the 2.x and 3.x branches.

This gets fixed to
from .html.entities import name2codepoint
because there is also a local module django.util.html. This is
incorrect; it should have converted it to

As a workaround, I now run
name2codepoint = __import__('html.entities').entities.name2codepoint

In Python 2.5.4 built from unmodified source:
showard at showardlt:~/src/Python-2.5.4$ ./python
Python 2.5.4 (r254:67916, Jan 7 2009, 20:28:41)

Type "help", "copyright", "credits" or "license" for more information.
>>> from xml.parsers import expat
>>> f=open('/tmp/foo')
>>> p=expat.ParserCreate()
>>> f.close()
>>> p.ParseFile(f)
Segmentation fault
The error is in the control flow in xmlparse_ParseFile()
(Modules/pyexpat.c:1000). When passed a real file object that's been
closed, PyFile_Check() returns true, but then PyFile_AsFile() returns 0
(since f_fp on the file object is set to zero when the file is closed).
So the local 'fp' is set to 0, and 'readmethod' is left as NULL. The
conditional at 1033 then fails, and the call to readinst() at 1041
passes readmethod=NULL, leading eventually to a segfault in
PyObject_Call at Objects/abstract.c:1860.
I think it's present in 2.6 as well, but I'm not sure. It seems to have
been fixed by chance in 3.0 because Guido removed the first branch in
xmlparse_ParseFile altogether in an unrelated change a while ago.
The attached patch simply checks for fp == 0 and raises an exception. I
don't know if it's the proper solution but you get the idea.
Built with the attached patch:

New submission from Kristj?n Valur J?nsson <kristjan at ccpgames.com>:
This is related to issue 4336. While that issue finally revolved around
fixing the Nagle problem for xmlrpc and other http clients, here I
propose to fix another performance bottleneck with xmlrpc, reading the
HTTP Headers.
HTTPResponse creates a socket.fileobject() with zero buffering which
means that the readline() operations used to read the headers become
very inefficient since individual socket.recv() calls are used for each
character.
The reason for this is to support users who subsequently do
socket.recv() on the underlying socket, and so we don't want to read too
much of the headers. Note that there is no example of this in the
standard library.
In the provided patch, I have removed some vestigial code from
xmrlpclib.py which attempted to use recv() even though it never did
(because the connection has been closed when HTTPConnection returns the
response). Even so, Guido has expressed his concern that we need to
keep the support for this recv() behaviour in place.
Therefore, I have added a new optional argument, nobuffer=True, which
users that promise not to call recv() can set to false. This will then
cause the generated fileobject from HTTPResponse to have default
buffering, greatly increasing the performance of the reading of the
headers.

New submission from Pablo Castagnino <pablo.castagnino at gmail.com>:
Something in python's timezone handling needs to be
updated. Python does not take into account 'daylight saving' clock time
changes.
The thing is my clock time is correct. If you
ask anyone here for the time, they will tell you it's X. However, Python
believes (correct) current time is X + 1 hour. In fact, this is the case
most of the time, but because of 'daylight saving' measures, official
time has been changed. So, without a doubt, this needs to be fixed.
A solution could be adding the possibility to set a 'daylight saving'
option which helps dealing with this. So, if I set this option to 3600
secs, then Python could +/- this remainder to the, let's call it,
'expected current time' according to the timezone.

the documentation I found after a couple hours of searching was it
mentioned that named groups can only be backreferenced _within_ the pattern.
In particular, the sections at
http://www.amk.ca/python/howto/regex/#SECTION000530000000000000000 and
the description of the (?P<name>) behavior at
http://docs.python.org/library/re.html could be modified to make it
clear that the named capture does not create a variable usable outside
of the pattern.
I would be happy to alter the documentation appropriately.

New submission from Luke Kenneth Casson Leighton <lkcl at lkcl.net>:
messy patches which get python 2.5.2 compiling - and producing
python.exe.so - under wine.
the setup.py is presently _wholly_ unsuited to use for building
the modules - get_sysconfig("srcdir") returns None because...
it's supposed to!
but, the actual libpython2.5.a and the actual python.exe _are_
successfully built - and, amazingly, useable.

New submission from Jeffrey Yasskin <jyasskin at gmail.com>:
glibc until 2.10 has a bug in gethostbyaddr_r that assumes the buffer
argument is 8-byte aligned
(http://sources.redhat.com/ml/libc-alpha/2009-01/msg00000.html). gcc
seems to always provide such alignment for the call in
socketmodule.c:socket_gethostbyaddr(), but llvm-gcc (possibly only HEAD,
not 2.4) does not, which causes a segfault in test_socket.py. The llvm
bug investigating the problem is http://llvm.org/bugs/show_bug.cgi?id=3233.
The attached patch specifies the alignment so that llvm-gcc and unfixed
glibcs work together.
I'll commit this tomorrow if there are no objections.

I'd like to suggest some improvements from mmap
1) mmap assign to slice only accepts a string. This is unfortunate,
because AFAIK a string can only be created by copying data, and this is
wasteful for large data transfers. mmap should accept any object
supporting buffer protocol as well as string.
2) buffer (mmap_obj) gives a read_only buffer. There should be a way to
make this read_write. I suggest 'as_buffer' member.
3) mmap_obj does not support weak ref. This is needed for proper
lifetime management using boost::python

__import__

Message-ID: <1231449686.43.0.781017317614.issue4886@psf.upfronthosting.co.za>
New submission from Michael Yang <yangofzeal at gmail.com>:
I want to use the included test.regrtest (located in
$pythondir/lib/python[ver]/test) to regression test some of my own
scripts located in directory myDir. The script has some nice
configurability features to skip some tests based on machine
configurations, etc. that a vanilla unittest suite doesn't include
automatically. However, it seems that the script regrtest.py has an
error following the __import__ line.
Here's my setup:
/sample.py
/myDir
/__init__.py
/test_file1.py
/test_file2.py
/...
in sample.py:
{{{
#!python
#!/usr/bin/env python
import test.regrtest as rt
rt.main(tests = ['myDir.test_file1','myDir.test_file2'], \
quiet = False, verbose = True)
}}}
running sample.py yields:
{{{
#!sh
myDir.test_file1
myDir.test_file1 skipped -- No module named myDir.test_file1
myDir.test_file2
myDir.test_file2 skipped -- No module named myDir.test_file2
2 tests skipped:
myDir.test_file1 myDir.test_file2
2 skips unexpected on win32:
myDir.test_file1 myDir.test_file2
}}}
This is due to the code snippet in regrtest.py around line 554:
{{{
#!python
...
if test.startswith('test.'):
abstest = test
else:
# Always import it from the test package
abstest = 'test.' + test
the_package = __import__(abstest, globals(), locals(), [])
the_module = getattr(the_package, test)
...
}}}
should be changed to:
{{{
#!python
...
if test.startswith('test.'):
abstest = test
modName = test[len('test.'):]
else:
# Always import it from the test package
abstest = 'test.' + test
modName = test
the_package = __import__(abstest, globals(), locals(), [])
the_module = getattr(the_package, modName)
...
}}}
This way, the the_module will correctly find the module name in
'the_package'.
A further recommendation: the main() module should be able to work with
test directories with name other than 'test.*'. Otherwise, users
wishing to use the main() on other directories will have to name them
'test.' Depending on the user's directory's position in sys.path
(before or after $pythondir/lib/python[ver]), regrtest.main() will
either fail due to the 'from test import ...' statements being shadowed
by the user's 'test' directory or the user's 'test' directory being
shadowed by the standard library's.

Subject: [New-bugs-announce] [issue4887] environment inspection and
manipulation API is buggy,
inconsistent with "Python philosophy" for wrapping native APIs
In-Reply-To: <1231452487.08.0.408278867366.issue4887@psf.upfronthosting.co.za>
Message-ID: <1231452487.08.0.408278867366.issue4887@psf.upfronthosting.co.za>
New submission from Jean-Paul Calderone <exarkun at divmod.com>:
According to a recent thread on python-dev, Python APIs with the same
name as native APIs can be trusted to just pass through to the platform
API call
(<http://mail.python.org/pipermail/python-dev/2009-January/084899.html>).
This isn't the case for the environment APIs in the os module. For
example, os.getenv doesn't always return the actual value of a key in
the environment. Instead, it looks in the os.environ pseudo-dict to get
the answer. This can be wrong because os.environ is a *copy* of the
environment which any non-Python API will use, and as a copy it can get
out of sync with the real environment. One way it can get out of sync
is via os.environ.pop (at least on POSIX - os.environ has different
implementations on different platforms, I find the way an implementation
is selected to be rather confusing and I have not tracked down the
precise behavior for all platforms):
>>> import os
>>> os.environ.pop('PATH')
'/home/exarkun/.local/sbin:/home/exarkun/.local/bin:/home/exarkun/Projects/combinator_paths/bincache:/home/exarkun/.local/sbin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/bin/X11:/usr/games'
>>> os.getenv('PATH')
>>> os.system("echo $PATH")
/home/exarkun/.local/sbin:/home/exarkun/.local/bin:/home/exarkun/Projects/combinator_paths/bincache:/home/exarkun/.local/sbin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/bin/X11:/usr/games
0
>>>
Another way is via calls to the platform environment manipulation APIs
(setenv, unsetenv or putenv). These might be invoked by a third-party
library which is exposed to Python or via ctypes.
`environ? itself is a C API, though it's a char**, whereas os.environ is
a Python dict. It's probably convenient for os.environ to remain as a
dict, since that's so much simpler to manipulate and inspect than the C
data structure used. However, it'd be good if were always in sync with
the real process environment. A good way to do this would probably be
to stop maintaining a copy of the environment and always pass through to
one of the platform APIs to satisfy a method call onto it.

New submission from Pratik Potnis <pratik.potnis at gmail.com>:
While using function HtmlDiff() from Library difflib, if there is
difference in caps of two strings it does not provide proper diff results.
Two strings in two different files in this context that I used are:
hostname vaijain123 and (this string is in small caps)
hostname CAVANC1001CR1 (This one is in large caps)
Expected behavior after diffing : It should show hostname changed (and
highlight it with Yellow color)
instead of this it is showing Added in one file and deleted in another
file. (Highlighting them with green and red color respectively)
When tried with same caps (either small or large) it shows expected
behavior(highlighting the strings in yellow color). Also with numbers it
works well.
I think its an issue with the CAPS of letters. difflib is not able to
differentiate between the caps of letters.

Quote of my original report:
(This is about the search function of the Text class in Tkinter.
An IndexError is raised when pattern == '')
...
>In addition I get an IndexError, if I delete the
>last character of the search string.
>Does Tk allow calling search with an empty pattern?

A further remark from Guilherme Polo (gpolo):
>For the suggestion about fixing the search method regarding the
>pattern:
>the fix is almost fine, but we need to disallow None as a pattern.
I do not understand that remark. Is it to avoid the TclError?
Or because the exception changes (IndexError -> TclError)?
What do you want to do when pattern == None? Raise ValueError
or IndexError (as before)?
Appended slightly simplified demo program from issue 1581476
and a patch against trunk r68445.

change breaks code

Message-ID: <1231499341.14.0.968854878286.issue4891@psf.upfronthosting.co.za>
New submission from Glenn Linderman <v+python at g.nevcal.com>:
External code that temporarily replaces warnings.formatwarning, a
technique used in IDLE and worked around (see issue 4043), is broken by
the addition of the optional parameter lineno to the formatwarning function.
While normal calls to functions can be "compatibly" extended with
additional optional parameters, that is not the case when the function
is substituted for, by matching its signature... if the signature is
extended, the code breaks on a Python upgrade, because the substituted
function doesn't know about the new parameter, and has fewer than are
being supplied by calls to the function.
Whether this is good, bad, documented, or appropriate, I don't know, but
it broke CherryPy 3.1.1 when running on Python 2.6, because of the new,
optional, lineno=None parameter to warnings.formatwarning
Not sure I have type and components right. I'm a newbie.
This problem probably also applies to 3.0, but I don't have the
environment to test it there at present.
I first described this problem on python-dev and the suggestion was made
to put it here (remainder of this comment is a quote):
This formatwarning compatibility problem between 2.5 and 2.6 is a bug.
Please file a new issue for this.

There is a separate file thread_wince.h for use with CE, but that is

CE and makes the file at least compile.
Note that this doesn't touch any working code, because the CE port is
currently broken anyway. Further, the changes compile, but since there
are various other bits and pieces still missing, it is impossible to

CE6 doesn't provide strdup() but provides an equivalent _strdup() in
stdlib.h. The attached patch simply #defines strdup _strdup after
including said header file.

Subject: [New-bugs-announce] [issue4896] Faster why variable manipulation in
ceval.c
In-Reply-To: <18791.24525.745699.580609@montanaro.dyndns.org>
Message-ID: <18791.24525.745699.580609@montanaro.dyndns.org>
New submission from Skip Montanaro <skip at pobox.com>:
The why_code enum in ceval.c has values which form a bit set. Comparison of
the why variable against multiple values is going to be faster using bitwise
operations instead of logical ones. For example, instead of
why == WHY_RETURN || why == WHY_CONTINUE
the equivalent bitwise expression is
why & (WHY_RETURN | WHY_CONTINUE)
which has fewer operations (one vs three treating the rhs of & as a
constant). This is already done in one place. The attached patch converts
all other expressions of the first form.
Also, there are some further manipulations of why in the loop after the
fast_block_end. The loop can only be entered if why != WHY_NOT. In the
loop when it is set to WHY_NOT, the loop breaks. There is thus no reason to
test its value in the while expression. Further, instead of just breaking
from the loop and then checking the why != WHY_NOT again, just jump past
that check by adding a why_not_here label.
The attached patch implements these changes (against the py3k branch). All
tests pass on my Mac except test_cmd_line (which has been failing for
awhile).

The documentation for PyIter_Next says it will raise TypeError if the
object passed to it is not an iterator. However, the implementation in
abstract.c performs an assert rather than raising TypeError. I would
prefer if the implementation were adjusted to match the documentation
rather than vice-versa.

New submission from Adeodato Sim? <dato at net.com.org.es>:
Hello.
I recently noticed that Bazaar's unified_diff() was emiting ---/+++
lines with a trailing whitespace if fromfiledate/tofiledate were the
empty string. (Which was bad because a program to detect spurious
trailing whitespace in diffs would flag them as errors.)
A patch [1] was committed recently in their tree. During the
discussion, it was pointed out that the affected function was a copy
of Python's own unified_diff() in difflib, which suffered the same
problem.
[1]: http://bazaar.launchpad.net/~bzr/bzr/trunk/revision/3923
I'm now attaching a patch to fix this issue in Python. It'd be great
if you'd consider applying it. (It seems that the correct character to
separate dates is a tab and not a space; if you feel changing this is
breaking backwards compatibility, feel free to s/\t/ / in my patch.)
Thanks.

New submission from Giovanni <dalloliogm at gmail.com>:
The doctest module should have support for fixtures (e.g. setUp and
tearDown methods).
It is very silly to be forced to always re-import all the modules needed
in every function tested with doctest.
For example, when you have to document functions that open files, you
have to import StringIO or TempFile, and then create a file, while this
could be done easily with a fixture.

Page 107 of api.pdf says that Py_TPFLAGS_HAVE_ITER is set if the type

the documentation of tp_iter and tp_iternext, it says "the next two fields
only exist if the Py_TPFLAGS_HAVE_CLASS flag bit is set".
Should the latter refer to Py_TPFLAGS_HAVE_ITER?

GetFileAttributes[W|A] returns a DWORD with this value when it
couldn't determine the file's attributes. In the Python codebase,
there are basically three values this is compared with, the above
macro, 0xffffffff and (DWORD)-1, it should only be the macro.
However, this macro isn't defined in some SDKs (I don't remember if
those were early MSVC versions or some MS Windows CE SDKs), so we also
need to work around that.
I'm currently preparing a patch that resolves those including the
workaround when the macro isn't defined.

GetLastError() is sometimes 0 when should be ERROR_NO_MORE_FILES.
This happens because, on debug build, Py_END_ALLOW_THREADS finally

The fragment
try:

s=StringIO.StringIO()
gets rewritten to
try:
import io as StringIO
except ImportError:
import io
s=io.StringIO()
Unfortunately, that code fails to work: the first import succeeds,
actually binding StringIO; the name io is unbound and gives NameError.
Apparently, the fixer choses to replace all occurrences of StringIO with
io; it should extend this replacement to "as" clauses.
My work-around is to import as _StringIO in both cases, and then refer
to the module as _StringIO.

'x.__long__() <==> long(x)'
But the long builtin no longer exists.
I'm actually not sure why the nb_long slot still exists in 3.x at all.
Can anyone enlighten me?

self._sampwidth
else:
self._file.write(data)
self._datawritten = self._datawritten + len(data) *
self._sampwidth
Note that the default (not byte swapped) assignment to _datawritten must
also be multiplied by _sampwidth. If not, audio programs will ignore the
second half of a 16-bit-sample file.
As a side note, the calls to _patchheader() do not need to be protected
by this "if" statement:
if self._datalength != self._datawritten:
_patchheader does the same test to optimize its operation.

In the Numeric Types documentation for 2.6, 3.0, and 3.1 trunc is
documented as a built-in, like round, but while there is a trunc in math
there is no built-in trunc. Read some of the debate on trunc from a year
ago convinced me that this discrepancy is a documentation problem not a
problem with the built-in functions. Sorry if I'm completely off target
here, but since I noticed I figured it was worth an issue.

The attached patch is for sysmodule.c, it contains two changes:
1. The check whether stdin is a directory is rewritten without using
fstat(), which doesn't exist under CE.
2. Replacing sys.argv[0] with the full path is skipped, CE doesn't have
a current working dir or paths relative to it, so it must already be an
absolute path.

1. Create Windows installer with Python 2.5 from attached project.
2. Install it with Python 2.6.1.
3. The post-installer will fail with error message:
*** run_installscript: internal error 0xFFFFFFFF ***
The code causing this is:
import socket
and the actual error is:
ImportError
DLL load failed: The specified module could not be found.
File "<string>", line 6, in windows_binary_install
File "c:\apps\python26\lib\socket.py", line 46, in <module>
import _socket
If the installer is created with Python 2.6.1, it works fine.
The problem was noticed in the Robot Framework project and the issue can
be found from http://code.google.com/p/robotframework/issues/detail?id=196.
This problem was first asked as part of issue
http://bugs.python.org/issue4566, but Martin v. L?wis recommended to
open new issue for this.

New submission from scott wedel <taverngeek at gmail.com>:
The HUGE_VAL aka infinity issue is solved if the LIB is -lsunmath -lm
instead of just -lm
Sun Studio 12 compiler also seems to choke on the PyByteArray_GET_SIZE
and _AS_STRING because those macros use the ',' operator to stuff an
assert before the pointer lookup. When I remove the assert portion of
those macros then they compile fine.
The assertions in those macros appear a bit silly because some places
they are used already have prior assertions and I don't see the point of
the macro which appears to be to crash due to an assertion one statement
prior to the null pointer reference causing a crash.
The configure process also appeared to make a few mistakes such as not
finding uid_t because that is in <sys/types.h> and not in the presumed
header file. If configure were to include the standard header files AND
the file that it expects to find the definition then it would be better
at finding what is defined. I don't know why Sun does that.

I haven't verified this through any test (actually I'm wondering how to
deterministically reproduce it), but logically there are cases where
gc.collect() (and, similarly, PyGC_Collect()) won't work as advertised.
Specifically, when the GC is asked to collect a given generation but a
younger generation is already being collected, collect() will simply
notice this and return 0. However, only the younger generation will have
been collected, not the generation asked by the user.
It wouldn't take too much effort to make gc.collect() and PyGC_Collect()
truely deterministic.

'=', return value of unsetenv() not checked

Message-ID: <1231803037.62.0.52390349364.issue4926@psf.upfronthosting.co.za>
New submission from David Watson <baikie at users.sourceforge.net>:
One of these problems interacts with the other, and can cause
os.unsetenv() to free memory that's still in use. Firstly,
calling os.putenv("FOO=BAR", "value") causes putenv(3) to be
called with the string "FOO=BAR=value", which sets a variable
called FOO, not FOO=BAR; hence, os.putenv() should not accept a
name with an "=" character in it.
The way this interacts with os.unsetenv() is that the string
(FOO=BAR=value) is stored in the internal dictionary object
posix_putenv_garbage under the key "FOO=BAR". The reference in
this dict is supposed to prevent the bytes object (str in 3.x on
Windows) that contains the string from being garbage collected
and freed until unsetenv() is called, since putenv(3) makes the
char **environ array point to the actual string, not a copy.
The problem with os.unsetenv() is that it does not check the
return value from unsetenv(3) at all and will unconditionally
remove the corresponding string from posix_putenv_garbage.
Following the example above, when os.unsetenv("FOO=BAR") is
called, unsetenv(3) will fail because the name contains an "="
character, but the object containing the string will be garbage
collected even though char **environ still has a pointer to it.
This is a bit tricky to give a visible demonstration of, but the
attached visibility.diff adds posix_putenv_garbage to the module
namespace and prints the return value from unsetenv() so you can
see what's going on.
The other two attached diffs fix the problems (for 2.x and 3.x
separately) by making os.unsetenv() raise OSError on failure in
the usual way, and os.putenv() raise ValueError when its first
argument contains "=". They also add test cases and docs. In
the patch for 3.x, some of the relevant code differs between Unix
and Windows; I changed both but I've only tested the Unix
version.

Subject: [New-bugs-announce] [issue4927] Inconsistent unicode repr for
fileobject
In-Reply-To: <1231838497.34.0.90195679535.issue4927@psf.upfronthosting.co.za>
Message-ID: <1231838497.34.0.90195679535.issue4927@psf.upfronthosting.co.za>
New submission from Kristj?n Valur J?nsson <kristjan at ccpgames.com>:
The repr for fileobjects is inconsistent. On windows:
f = file("tmp\\foo", "wb")
f
<open file 'tmp\foo', mode 'wb' at ...>
f = file(u"tmp\\foo", "wb")
f
<open file u'tmp\\foo', mode 'wb' at ...>
For unicode, the filename is a proper "repr", but for a string it is
just the plain string, enclosed in single quotes. Note that I consider
the string case in error. Like the repr of a list or tuple, it should
be a string containin the repr of its components.
This leads to problems in the testsuite on vista.
I propose to change this with the patch provided, which always displays
the repr of the filename. It may have side effects in the testsuite, I
will add a separate file for that.

New submission from Richard Philips <rphilips at users.sourceforge.net>:
On Solaris 10 (Solaris 10 5/08 s10x_u5wos_10 X86),
with python 2.5 (Python 2.5.2 (r252:60911, Sep 8 2008, 16:53:36) [C] on
sunos5),
tempfile.NamedTemporaryFile creates - as advertised - a temporary file.
After closing this file object (e.g. by exiting the python process), the
temporary file is indeed removed.
But if you just kill the python process, the temporary file is not
destroyed.
This behavior is different on Red Hat Linux and MS Vista, on these OSes
the temporary file is removed.
A snapshot to illustrate the behavior:
[moto /]# python
Python 2.5.2 (r252:60911, Sep 8 2008, 16:53:36) [C] on sunos5
Type "help", "copyright", "credits" or "license" for more information.
>>> import os, tempfile
>>> f = tempfile.NamedTemporaryFile()
>>> f.name
'/tmp/tmpfHraUd'
>>> os.getpid()
4403
>>> x = "With root priveleges, I execute: 'kill 4403'"
>>>
>>> Terminated

Today I was trying to compile a module using an extension in C and
noticed there are differences between compiling it on Python 2.5 and 2.6.
I was trying to compile psutil (svn checkout

problem may occur with any other package using C extensions.
Python 2.5:
D:\pyftpdlib\svn\psutil\trunk>C:\python25\python.exe setup.py install
running install

running build_ext
error: Python was built with Visual Studio 2003;
extensions must be built with a compiler than can generate compatible
binaries.
Visual Studio 2003 was not found on this system. If you have Cygwin
installed,
you can try compiling with MingW32, by passing "-c mingw32" to setup.py.
Python 2.6:

This happens on a 32-bit build on a 64-bit system, which happens to have

if sys.maxsize < (1 << 32) and struct.calcsize('P') == 4:
self.assertRaises(OverflowError,

Modifying one of the stringlib files does not trigger recompiling of
Objects/bytearray.c, although the latter includes the former.

With attached x.py:
$ cat x.py
"""
>>> foo()
"""
def foo():
1/0
if __name__ == '__main__':
import doctest, pdb
try:
doctest.testmod(raise_on_error=True)
except doctest.UnexpectedException, e:
pdb.post_mortem(e.exc_info[2])
$ ./python.exe x.py

-> 1/0
(Pdb) up
> <doctest __main__[0]>(1)<module>()
(Pdb) l
[EOF]
Apparently the problem is that the default getlines gets restored in the
"finally:" section in DocTestRunner.run() before post_mortem is invoked.
The only solution that comes to mind is to patch pdb.post_mortem
similarly to the way pdb.set_trace is patched but not restore it until
the end of testmod().
Am I missing a simpler solution?

New submission from rech <r.rechkemmer at web.de>:
A common pattern is to check numeric input like this:
a = input()
try:
int(a) # or float(a)
except ValueError:
print("Bad input")
One would expect this to work with decimal.Decimal(a), too. But, as
Decimal.__init__ raises decimal.InvalidOperation instead of a
ValueError, it fails.
Making Decimal.__init__ raise a ValueError in this context would be an
incompatible change. Also, making decimal.InvalidOperation a subclass of
ValueError might not be correct.
It would be best to create a new an more specific exception for this
case, a subclass of both decimal.InvalidOperation and ValueError. This
would keep all functionality and enable this kind of intuitive use.

Subject: [New-bugs-announce] [issue4941] Tell GCC Py_DECREF is unlikely to
call the destructor

Message-ID: <1231899030.81.0.577768364365.issue4941@psf.upfronthosting.co.za>
New submission from Daniel Diniz <ajaksu at gmail.com>:
As suggested by Paolo Giarrusso, add a "likely()" to Py_DECREF, telling
GCC it doesn't call the destructor in the common path.
This optimization seems to interact well with #4896 and to be slower on
top of #4753 on my system. Patching ceval.c instead of object.h seems to
give the same result, FWIW. Benchmarks most welcome :)
Paolo Giarrusso wrote:
"Anyway, yesterday I was looking at the assembly and I realized that
GCC optimizes the case where Py_DECREF calls the destructor! Since I
don't have time for this, can you hint GCC for the better by adding
unlikely() to Py_DECREF, at least (or maybe only) for ceval.c, or
maybe even only for the main interpreter?"

New submission from Hamish Moffatt <hamish at cloud.net.au>:
As of 2.5.3, calling accept() on an AF_UNIX socket fails on arm. The
following exception occurs:
SystemError: Negative size passed to PyString_FromStringAndSize
I have attached a test program that creates a socket and connects to it.
It works on x86-64 but fails on armeb (gcc 4.1.2).
This failure has been noted a few times by the arm buildbot too:
http://archives.free.net.ph/message/20081012.121034.89069ea2.en.html
It's already fixed in 2.6.x in rev 60214. I applied the same change to
2.5.4 and the problem was resolved.

can't write results file for modules loaded by __path__ manipulation

New submission from Matt McClure <mlm at aya.yale.edu>:
The function trace.CoverageResults.write_results() can't write coverage
results on Windows for modules loaded by using the __path__ feature of
PEP 302.
For example, Bazaar uses the __path__ feature to load plugins from
directories specified by the BZR_PLUGIN_PATH environment variable.
The attached zip file contains a test case. If it is unpacked so that
tracebug.py is in C:\, it will fail to produce a coverage results file
for C:\tracebug\dir2\hello.py. Instead it will produce an empty file
named C:\tracebug\out\C .
The bug appears to be that trace.fullmodname() returns
C:.tracebug.dir2.hello . Since the result contains a colon (:), it
can't be used as the filename of the output file produced by
trace.CoverageResults.write_results().

in Windows

New submission from Javen Wang <javen72 at gmail.com>:
I encountered a very strange issue in file flush operation in Windows.
Here's the scenario of my application:
1. The main thread of my application will create makefiles sequentially.
2. Once a makefile is generated, launch a separate process calling
nmake.exe to run it in parallell. The main thread then create another
makefile until no more makefiles to create.
3. The number of new processes is limited by command line options.
My application has been running for almost a year without any problem.
But, after I made some changes recently to the content of makefile
generated, "nmake.exe" in separate process sometimes complains that
the makefile was not found. But when I went into the directory, the
makefile was there.
Because I didn't change any thing related to file creation and the new
makefiles are a little bit less than before, I guessed that the
makefile just created hasn't been flushed to disk because of size
change so the new process could not see it in a short time.
So I decided add code to force flush file buffer after writing the
file content (I didn't flush the file explicitly before). I did it
like below:
Fd = open(File, "w")
Fd.write(Content)
Fd.flush()
os.fsync(Fd.fileno())
Fd.close()
The strangest thing happened. The "makefile" missing happened more
frequently than no flush operation. I searched the web but no answer
there.
Finally I tried to use Windows file API to create the file via pywin32
extension. The problem's gone.
import win32file
Fd = win32file.CreateFile(
File,
win32file.GENERIC_WRITE,
0,
None,
win32file.CREATE_ALWAYS,
win32file.FILE_ATTRIBUTE_NORMAL,
None
)
win32file.WriteFile(Fd, str(Content), None)
win32file.FlushFileBuffers(Fd)
win32file.CloseHandle(Fd)
I tried writing small python extension in C to make use Windows API to
create file like above. It also works well, even I removed the
FlushFileBuffers() calling.
I think that there's a bug in Python file buffer mechanism.

json compares arguments against True/False by identity, not by boolean
value; by example:
if (skipkeys is False and ensure_ascii is True and
check_circular is True and allow_nan is True ...
Using `ensure_ascii=1` won't work as intended. I don't see the reason
to check those values by identity - they *are* boolean flags, and
should be checked by value, as the usual practice.
The attached patch fixes the code and documentation (and a bug encoding
True/False as keys, including unit tests)

Hi,
I am newbie for python under the windows.
I find that the cgi module always work wrong for the binary files to upload.
I find that it cannot auto to discern the files' mode and alway use the
default mode : 'TEXT'.
So I want to change the sys.stdin 's mode to BINARY to support the
binary files.
I got this way:
import msvcrt,os
msvcrt.setmode(0,os.O_BINARY) # for stdin
msvcrt.setmode(1,os.O_BINARY) # for stdout
but it isn't work,too.
I know use C progam language can use this function:
freopen("somefilename","mode","stdin or stdout") to redirect the file
flow.
Can every one help me ?
Best Regards
oopos

Subject: [New-bugs-announce] [issue4954] native build of python win32 using
msys under wine.

Message-ID: <1232054464.28.0.565807306717.issue4954@psf.upfronthosting.co.za>
New submission from Luke Kenneth Casson Leighton <lkcl at lkcl.net>:
this patch uses work from #3871 to get a build of python for win32
by running msys under Wine, the windows emulator, on linux.
no proprietary operating system or proprietary software was used.
/bin/sh.exe is so xxxxing unbelievably slow on msys under wine
(each sh.exe takes two seconds to start up, loads 240 fonts
and 40 libraries) that running configure was completely intolerable.
consequently, given that PC/config.h is perfectly useable on nt,
this patch totally bypasses the majority of autoconf tests, and
thus cuts the configure time down from three hours to (only!)
fifteen minutes.
configure must be run as:
./configure --prefix/python25 --enable-win32build=yes \
--enable=shared=yes
there is an additional bug in msys /bin/sh which stops python.exe
from executing scripts that are handed to it on the command-line.
scripts that are fed as standard-input are absolutely fine
(even the same script). running the same script from python.exe
from wineconsole cmd prompt is _also_ fine.
as a result, the build process terminates at:
./python.exe -E setup.py build
to complete the build, "wineconsole cmd" must be run, cd $(BUILDDIR)
and then run the commands manually:
./python.exe -E setup.py build
./python.exe -E setup.py install
then, back in the borked /bin/sh.exe, make install can be run.
stunningly, this does actually work: python.exe is build,
libpython2.5.dll and libpython2.5.dll.a are built... amazing.
other necessary workarounds:
* gcc -shared .... --out-implib=libpython2.5.dll.a .... etc fails
spectacularly to create both the .a implib _and_ the .dll.
consequently, it was necessary to split these up and use dlltool
to create the dll, implib and .def file etc. etc.
* ar and ranlib on msys, versions 2.16, 2.17 _and_ 2.19 of binutils
are borked. 2.16 and 2.17 throw an exception; 2.19 segfaults.
consequently, building of $LIBRARY had to be terminated with
prejudice. --enable-shared=no will fail miserably.
regarding testing: it's all a bit... odd.
* ctypes tests cause segfaults! the S8H one manages a segfault
all on its own, but there are other tests that cause corruption
that only shows up later... euurgh.
* builtin test_open fails due to putting \r\n instead of \n in the file
* test_file.py gets a sharing violation
* test_str gets a great one!

ahh, this is gooood :)
overall it's a damn good start - i'm dead impressed with
wine and msys in that they exist at all.
compiling and testing python under wine + msys should help
test and improve both those projects, and both this patch
and #3871 will help get python off of its dependence on
proprietary software.

The attached program demonstrates that the ContentHandler.skippedEntity
callback is not invoked for all skipped entities. Specifically, it is
not invoked for those in attribute values. Additionally, it
demonstrates that when parsing a document with no DOCTYPE, skippedEntity
is not called at all; instead the parser raises an exception about an
"undefined entity".

New submission from Kristj?n Valur J?nsson <kristjan at ccpgames.com>:
I stumbled upon this. Of all the errors in the posixmodule.c, ftruncate
alone raises an IOError upon failure. All the others raise OSError.
This behaviour is not documented. However, the os module documentation
says>
Note
All functions in this module raise OSError in the case of invalid or
inaccessible file names and paths, or other arguments that have the
correct type, but are not accepted by the operating system.
This came to light when I added tests to verify that exceptions were
being raised by invalid file descriptors.
I propose to fix this to comply with the docs.

Hello.
I have dedicated mail server at home
and it holds about 1G of mail.
Most of mail is in non UTF-8 codepage, so today
I wrote little script that should recode
all letters to UTF. But I found that
email.header.decode_header parses some headers wrong.
For example, header
Content-Type: application/x-msword; name="2008
=?windows-1251?B?wu7v8O7x+w==?= 2 =?windows-1251?B?4+7kIDgwONUwMC5kb2M=?="
parsed as
[('application/x-msword; name="2008', None),
('\xc2\xee\xef\xf0\xee\xf1\xfb', 'windows-1251'), ('2
=?windows-1251?B?4+7kIDgwONUwMC5kb2M=?="', None)]
that is obviously wrong.
Now I'm playing with email/header.py file in
python 2.5 debian package
(but it's same in 2.6.1 version except that all <> changed to !=).
If it's patched with

Hi,

formatargspec now handles keyword only args that don't have defaults.

New submission from eb303 <eric.brunel at pragmadev.com>:
Scenario to reproduce the problem:
- Run the attached script.
- Click the 'Ask confirm' button and answer 'Yes'; it should print
True, which is the expected answer.
- Click the 'Ask file' button, select any file and confirm.
- Click the 'Ask confirm' button and answer 'Yes'.
The script prints False, which is obviously wrong.
Problem reproduced on Linux Red Hat Fedora Core 4, Suse Enterprise
Linux 9, Solaris 8 for Sparc and Solaris 10 on Intel. The script works
as expected on Windows 2000, so it seems to be Unix-specific.
Possible cause: the result of the _show function in tkMessageBox is not
always a string, apparently depending on what happened before. Changing
the last line to:
return str(res)
seemed to correct the problem for me.

changes after mimetypes.init()

New submission from S Arrowsmith <siona at chiark.greenend.org.uk>:
Asking mimetypes to reload mime.types can cause guess_extension() to
return a different result if multiple extensions are mapped to that mime
type:
>>> import mimetypes
>>> mimetypes.guess_extension('image/jpeg')
'.jpe'
>>> mimetypes.init()
>>> mimetypes.guess_extension('image/jpeg')
'.jpeg'
>>>
This is because both the forward (extension to type) and inverse (type
to extension) type mapping dicts are populated by iterating through the
existing forward (extension to type) dict (types_map), then supplemented
by reading from mime.types (or any other files given to init()). The
fully populated forward dict becomes the new types_map. Initially,
types_map is hard-coded, but when the type mapping dicts are
repopulated, by explicitly or implicitly calling init() again, it is
done by iterating over the types_map created by the first init() call,
not the hard-coded one. If the iteration order for a set of extensions
with the same type is different in these two versions of the forward
dict, the order of extensions appearing for that type in the inverse
dict will change. And so the behavior of guess_all_extensions() and
hence guess_extension() will change.

New submission from Guido van Rossum <guido at python.org>:
I am attaching a file encoded in UTF-16 (with bom) which causes the
stream codec employed by the file reader to barf when reading by lines.
However reading the file in binary mode and decoding it in one fell
swoop works fine, and reading the whole text file with text() also works
fine; so I believe the data in the file is not corrupt (it started out
as an export of my Gmail contacts, but I x-ed out all printable ASCII
characters).
>>> x = open('contacts.csv', 'rb').read().decode('utf16') # OK
>>> x = open('contacts.csv', encoding='utf16').read() # OK
>>> x = open('contacts.csv', encoding='utf16').readlines() # Dies

UnicodeDecodeError: 'utf16' codec can't decode byte 0x00 in position 0:

Making certain modifications to the file elicits slightly different
error messages (e.g. "'utf16' codec can't decode bytes in position
90-91: illegal encoding" when I swap the second and first half of the
file) so it looks like some kind of data corruption in the codec's state
management or in the code in io.py that feeds the codec its data.

In the Windows help version of the docs that come with the Windows .msi

In the html versions at docs.python.org, there is one scroll bar and the
index disappears when one moves very far down the page. If sensibly
possible, decoupling index and context would be nice. Please pardon my
ignorance if not.

New submission from Terry J. Reedy <tjreedy at udel.edu>:
Issues and suggestions for Python Standard Library / Built-in Types /
"Sequence Types ? str, bytes, bytearray, list, tuple, range"
1. Put subsections in the same order as in the title and main section.
In particular, move bytes/bytearray subsection up to follow string
subsection and move range subsection down to bottom of this grouping.
2. String paragraph (the second) ends with the rather wordy sentence
"In addition to the functionality described here, there are also
string-specific methods described in the String Methods section."
where 'String Methods' is a forward link to that subsection.
Add similar possibly less wordy sentence-links for other types.
In particular, end next (byte/bytearray) paragraph with something like
"For specific methods, see String Methods and Bytes and Byte Array
Methods. For bytearrays, also see Mutable Sequence Types."
End the list/tuple paragraph after the Warning with
"For list methods, see Mutable Sequence Types."
After the following range paragraph, the following could be added:
"For more, see Range Type."
However, there is almost nothing more said (perhaps there was before
range objects were stripped down), so I suggest deleting that subsection
and adding anything more that is not duplication to the end of the
beginning section's range paragraph. If tuples do not need their own
section, range needs one even less.
3. Bytes and Byte Array Method subsection correctly says that bytes and
bytearrays do not have (senseless) .encode but neglects to document the
corresponding inverse .decode method (while it does mention the
specialized .fromhex decoding method).
Also add .isdecimal, .isnumeric, .isprintable, and .maketrans to the
list of exceptions in the first sentence. (Based on dir(str), dir(bytes)
in 3.0)
4. I see three problems with the current documentation of count and
index methods.
a) They are documented under both String Methods and Mutable Sequences.
They do not really belong in the latter, which lists "additional
operations that allow in-place modification of the object", because they
do not mutate.
b) Tuples do not have their own a section, but (unlike range objects) do
have a couple of methods: count and index. Being neither string-like
nor mutable, their having methods is undocumented.
c) Bytearrays, on the other hand, are both string-like and mutable. So
they are (mis)documented as having two slightly different versions of
these methods. (They actually use the string-like definition, of course.)
Consequently, the definitions of count and index in the Mutable Sequence
subsection are not mutable sequence definitions but are really
list/tuple definitions. So I suggest one of two variations:
A) In the main section, add the list/tuple version of .count() and
.index() to the table of common sequence operations with a footnote
either explaining the difference for the string group or referring to
String Methods.
B) In the main section, add both versions to the table with footnotes
explaining which is which.
The count/index/tuple doc issue has come up more than once on c.l.p.

Subject: [New-bugs-announce] [issue4967] Bugs in _ssl object read() when a
buffer is specified
In-Reply-To: <1232159812.52.0.781690409094.issue4967@psf.upfronthosting.co.za>
Message-ID: <1232159812.52.0.781690409094.issue4967@psf.upfronthosting.co.za>
New submission from Antoine Pitrou <pitrou at free.fr>:
The read() method on ssl objects can take a buffer as a parameter, but
the method is buggy in this case:
- it only accepts bytearrays, while it should accept any object
supporting the buffer protocol in write mode
- when the object is not a bytearray, it returns NULL without setting
the current exception
- since it doesn't attempt to get a buffer export from the object, there
is no protection and the buffer could be resized while the method
releases the GIL, leading to a likely crash
This patch solves all three issues. Note that I'm not able to write an
unit test for it, because test_ssl.py is too high-level (it looks more
like functional tests than unit tests). Also, the only reason I
discovered this is that it made some tests fail on the io-in-C branch
(which uses readinto() a lot). I'm a complete SSL newbie.

Message-ID: <1232162769.03.0.624026715862.issue4968@psf.upfronthosting.co.za>
New submission from Terry J. Reedy <tjreedy at udel.edu>:
inspect module in 3.0
.isclass: says "Return true if the object is a class." Since the issue
of builtin versus Python coded is involved in all the other methods
below, I would expand this to
"Return true if the object is a class, whether built-in or Python-coded."
to emphasize that this is not an issue for this one.
.isfunction: current "Return true if the object is a Python function or
unnamed (lambda) function." falsely implies that there is such a thing
as 'unnamed (lambda) function; different from 'Python function'. By
test, it just returns True for 'function' objects. Suggestion:
"Return true for Python-coded functions, including unbound Python-coded
methods." or possibly
"Return true for functions created by def statements and lambda
expressions, including unbound Python-coded methods.
.ismethod: "Return true if the object is a method." should be specified
to something like
"Return true if the object is a bound method written in Python."
.isbuiltin: says "Return true if the object is a built-in function."
but actually tests for membership in class 'builtin_function_or_method'.
I believe that truth is
"Return true if the object is a built-in function (but not a class) or a
bound built-in non-special method."
It is True, for instance, for [].append but not [].__hash__. I am
assuming that this behavior is intended and not a bug.
.ismethoddescriptor: "Return true if the object is a method descriptor,
but not if ismethod() or isclass() or isfunction() are true." begs the
question of what a method descriptor is. I believe the following is
both true and clearer.
"Return true if the object is a built-in method and isbuiltin() is false.
I would follow with
"The methods isclass, isfunction, ismethod, isbuiltin, and
ismethoddescriptor are mutually exclusive."
I believe the following is true, and could be added also.
"Exact one is true for any instance of a built-in callable class."

The mimetypes module has a built-in default database, and, in addition,
reads mime.types files from a list of standard places (/etc/mime.types
by example)
On Windows, those files usually don't even present; MIME information is
stored in the registry instead. Until now, the mimetypes module just
ignored those settings; this patch adds support for reading the MIME
database from the Windows registry.

The x86 gentoo 3.0 and 3.x buildbots have been failing for a while at the test stage, with:
make: *** [buildbottest] Unknown signal 32

I noticed a common denominator with these failures, which is that they always seem to occur a few tests after
test_os has been run. So it looks as though something in test_os is causing this.
Can anyone reproduce this (I can't on any of the machines I have access to), and (e.g., by trial and error) identify
which of the test_os tests is causing this?

New submission from Matthew Barnett <python at mrabarnett.plus.com>:
I've found that the following 4 Unicode characters/codepoints don't
behave as I'd expect: ? (U+01C5), ? (U+01C8), ? (U+01CB), ? (U+01F2).
For example, u'\u01C5'.istitle() returns True and
unicodedata.category(u'\u01C5') returns 'Lt', but u'\u01C5'.title()
returns u'\u01C4' (?), which is the uppercase equivalent.
I believe that these 4 codepoints are the only ones where the titlecase
differs from uppercase.
I thought it might be a mistake in the Unicode database. However John
Machin says:
Doesn't look like it. AFAICT it's a mistake in Objects/unicodetype.c,
function _PyUnicode_ToTitlecase.
See
http://svn.python.org/view/python/trunk/Objects/unicodectype.c?rev=66362&view=markup
The code that says:
if (ctype->title)
delta = ctype->title;
else
delta = ctype->upper;
should IMHO merely be:
delta = ctype->title;
A value of zero for ctype->title should be interpreted simply as the
offset to add to the ordinal, as it is in the sibling _PyUnicode_To
(Upper|Lower)case functions. See also Tools/unicode/makeunicodedata.py
which treats upper, lower and title identically when preparing the
tables used by those 3 functions.
AFAICT making that change will fix the problem for those four
characters and not ruin any others.
The error that you noticed occurs as far back as I've looked (2.1) and
also occurs in 3.0.

list and tuple "classes" shouldn't be in that second sentence, should

the assumption is made that the result will fit into a PyInt.
obviously, on a 32-bit system, where SIZEOF_LONG is 4 bytes,
that ain't happening.
a complex test would be something like this:
if len <= 9: it's an int, definitely.
if len > 10: it's a long, definitely.
if len == 10, and first char is a "-", it's an int, definitely
if len == 10, and first char is 5,6,7,8,9, it's a long, definitely.
if len == 10, and first char is 0,1,2,3, it's an int, definitely.
if len == 10, and first char is 4, it _might_ be a long, but it might
also be an int, so... uh... let's assume it's a long!
and you know what? xxxx that for a game of soldiers: just use
"if len >= 10" assume it's a long :)

limit
In-Reply-To: <1232236998.05.0.906555449746.issue4979@psf.upfronthosting.co.za>
Message-ID: <1232236998.05.0.906555449746.issue4979@psf.upfronthosting.co.za>
New submission from Max Hailperin <max at gustavus.edu>:
The documentation for random.uniform says that random.uniform(a,b)
should return a number strictly less than b, assuming a<b. (The result
should be strictly less than a if a>b.) Thus both of the following
expressions should always evaluate to False:
a<b and b in [random.uniform(a,b) for i in range(20)]
a<b and b in [random.uniform(b,a) for i in range(20)]
Yet both of them evaluate to True (except, presumably, one time in a
million) after doing the following assignments:
a = 1.0
b = 1.0 + 2.0**-52
Other values of a and b also exist for which random.uniform will
sometimes return its upper limit. (For example, the -52 can be
increased to -51, -50, etc., with correspondingly less frequent
violations of the spec.)
Because this is a case where the code is violating an explicit
specification in the documentation, I'm reporting it as a behavior bug.
But perhaps the behavior is as intended and the documentation is at
fault. For that reason, I'm also emailing docs at python.org.
The documentation would in any case need a little touching up, in that
it has a self-contradictory specification for the case where a=b. There
is no value N for which a<=N<b, given a=b. That minor touch-up could be
combined with allowing the behavior described in this bug report, if
that behavior is in fact desired.

There are five sequence types: strings, byte sequences, byte arrays,

However, subsequent discussion, as well as reality, use the term "bytes"
not "byte sequences".

I upgraded to tk8.5, idle still does the same thing.
To recreate type:
rm foo.py
idle foo.py
# The idle window briefly appears, then disappears, the process hangs

In previous versions of idle any nonexistent files would be created by
idle. This is what one would expect.
I have a patch for idlelib/PyShell.py that will make idle create any
nonexisting files.

Confusion in Documentation
In-Reply-To: <1232286351.49.0.0947913998579.issue4986@psf.upfronthosting.co.za>
Message-ID: <1232286351.49.0.0947913998579.issue4986@psf.upfronthosting.co.za>
New submission from andrew cooke <andrew at acooke.org>:
There's a small confusion in terminology in the documentation related to
methods that implement augmented assignment.
The "Expressions" section of the language reference ("Simple
statements") refers to augmented assignment -
http://docs.python.org/3.0/reference/simple_stmts.html#augmented-assignment-statements
- and this seems to be a carefully chosen (and correct) phrase because
the parsing is related to assignments, which are augmented with various
operators.
It is important to note that augmented assignments ("+=" etc) are *not*
parsed as operators. It is syntax error to use them in many places
where an operator would be accepted.
In the "Data Model" section, however, things are less clear
http://docs.python.org/3.0/reference/datamodel.html#emulating-numeric-types
. The methods used to implement augmented assignment are grouped near
those used to implement arithmetic operators. That seems natural. But
the text confuses the two more than is strictly necessary. In
particular there is the phrase "augmented arithmetic operations".
As I have already tried to make clear, these are not operations. They
are augmented assignments. Calling them operations is misleading,
because they cannot be used in the same places as "real" operations -
the parser simply will not accept them.
Apart from changing "augmented arithmetic operations" to "augmented
assignments" it might be worth adding some kind of note that explains to
the user that the parser calls those methods to implement assignment,
and that they are not valid in the same syntax as operations.
I am not sure the following will help, but it does illustrate the
confusion caused -
http://groups.google.com/group/comp.lang.python/browse_thread/thread/f1322928300b2b71
Cheers, Andrew

I was looking for some library to handle calendar events. Something PIM-
style, something useful, that could check if, for example, 2 weekly
repeated events that start on Monday morning and last until December
conflict with each other.
Then I found 'calendar' module in the standard library.
My question: how this thing ever made it to the standard library?
Maybe it was useful back in the days, if somebody could not get BSD or
GNU sources for cal(1) . Nowadays, even if it is able to print HTML
calendars, lets face it - who will use that functionality? You can
easily find HTML calendars with a lot of JavaScript support, that can be
customised in a thousands of ways.
I suggest we delete this module completly.

In the yield statement documentation

the old way of calling generators is used:
"The body of the generator function is executed by calling the
generator?s next() method repeatedly until it raises an exception."
This should be changed to something like:
"The body of the generator function is executed by calling the next()
function on the generator repeatedly until it raises an exception."
Or just replace next() with __next__(), and fix the next paragraph as well.

The documentation says io.TextIOWrapper wraps io.BufferedIOBase raw
stream. In the code, io.TextIOWrapper.read(),
io.TextIOWrapper._read_chunk() calls buffer.read1() which seems
expecting buffer to be an instance of io.BufferedReader. I'm not sure
which is correct right now.

xml.sax.saxutils.XMLGenerator._write tests the argument by
isinstance(text, str), but this is problematic in Python 3.0.
XMLGenerator accepts encoding and the produced file is encoded by that
encoding, i.e., the XML is a binary sequence. So IMHO, the XMLGenerator
constructor argument should be a subclass of io.RawIOBase.

Here is a copy-paste from the python3 documentation:
Without a __dict__ variable, instances cannot be assigned new variables
not listed in the __slots__ definition. Attempts to assign to an
unlisted variable name raises AttributeError. If dynamic assignment of
new variables is desired, then add '__dict__' to the sequence of strings
in the __slots__ declaration.
Any non-string iterable may be assigned to __slots__. Mappings may also
be used; however, in the future, special meaning may be assigned to the
values corresponding to each key.

Message-ID: <1232369845.16.0.0391307501892.issue4999@psf.upfronthosting.co.za>
New submission from Fr?d?ric Sagnes <speedup+python at gmail.com>:
Objects contained in a multiprocessing.Queue object are not comming out
of the queue in the same order as they went in. For instance, if I put
in object1, object2 and object3 in this very time sequence from multiple
processes, they can end up comming out of the queue as object2, object1
then object3 instead of the original order.
When using the threading module instead of multiprocessing everything is
fine.
The provided test script adds strings to the queue with timestamps.
These messages are not ordered by timestamp when they are printed. This
is an output of the test script with format "[pid at time] message":
[2120 at 00406] Got lock
[2120 at 02424] Released lock

Using print to print the message immediatly prints the messages in the

New submission from 0x666 <vasiliauskas.agnius at gmail.com>:
I think something wrong with implementation of multiprocessing module.
I`ve run this very simple test on my machine (core 2, vista):
import multiprocessing as mul
from time import time
def f(x):
return x*x
if __name__ == '__main__':
print "-------- testing multiprocessing on ",mul.cpu_count(),"cores
----------"
print ""
elements = 100000
pool = mul.Pool(processes=mul.cpu_count())
t1 = time()
res_par = pool.map(f, range(elements))
t2 = time()
res_seq = map(f, range(elements))
t3 = time()
res_app = [pool.apply_async(f,(x,)) for x in range(elements)]
res_app = [result.get() for result in res_app]
t4 = time()
print len(res_seq),"elements","map() time",(t3-t2),"s"
print len(res_par),"elements","pool.map() time",(t2-t1),"s"
print len(res_app),"elements","pool.apply_async() time", (t4-t3),"s"
print
raw_input("press enter to exit...")
__________________________________________
Results:
-------- testing multiprocessing on 2 cores -----------
100000 elements map() time 0.0269 s
100000 elements pool.map() time 0.108 s
100000 elements pool.apply_async() time 10.567 s
--------------------------------------------------------
IMHO, execution on 2 cores should be 1.x - 2 times faster than compared
with non-parallel execution. (at least in simple cases).
If you dont believe in this, check http://www.parallelpython.com/
module (demo example sum_primes.py), which fits very well this idea.
So how it can be that parallel pool.map() method executes in about 5
times SLOWER, than ordinary map() function ?
So please correct multiprocessing package to work in more-less
perfomance predictable way (like parallelpython).

New submission from Jesse Noller <jnoller at gmail.com>:
Right now, the multiprocessing code is littered with statements like:
assert self._popen is None, 'cannot start a process twice'
assert self._parent_pid == os.getpid(), \
'can only start a process object created by current
process'
assert not _current_process._daemonic, \
'daemonic processes are not allowed to have children'
These will obviously be stripped out if running in optimized mode -
however its not cool to rely on these anyway, the code should be
refactored to proper checks, e.g.:
if not hasattr(lock, 'acquire'):
raise AttributeError("'%r' has no method 'acquire'" % lock)

New submission from Daniel Frnake <dfranke at wellohorld.com>:
On Linux and presumably on other POSIX-like systems, socket.getfqdn()
doesn't work if a system resolves its own FQDN using DNS rather than
/etc/hosts.
My system's FQDN is 'fugue.tank.wellohorld.com'. My /etc/hosts is empty
except for loopback entries, and /etc/resolv.conf contains the line
'domain tank.wellohorld.com'. This is sufficient for 'hostname -f' to
do the Right Thing, but socket.getfqdn() simply returns 'fugue':

New submission from STINNER Victor <victor.stinner at haypocalc.com>:
The following code must display 3 instead of 0:
---
with open("x", "w") as f:
f.write("xxx")
with open("x", "a") as f:
print(f.tell())
---
The example works with Python 2.x, because file object is implemented
using the FILE structure (fopen, ftell, etc.). fopen() "fixes" the
offset if the file is opened in append mode, whereas open() doesn't do
this for us :
---
import os
with open("x", "w") as f:
f.write("xxx")
fd = os.open("x", os.O_RDONLY | os.O_APPEND)
print(os.lseek(fd, 0, 1))
---
display 0 instead of 3 on Python 2.x and 3.x.
It becomes a little bit more weird when you write something :-)
---
with open("x", "w") as f:
f.write("xxx")
with open("x", "a") as f:
f.write("y")
print(f.tell())
---
displays... 4 (the correct position) on Python 2.x and 3.x.
I see (in GNU libc source code) that fopen() call lseek(fd, 0,
SEEK_END) if the file is opened in append mode.

http://mail.python.org/pipermail/python-checkins/2009-January/077474.html
probably indicates some other error in the manager's shared objects, but
the debug_info() function fails to display anything.
It seems that most keys in id_to_obj are strings ('%x' % id(obj)) except
the first one which is zero. And since python 3, you cannot compare 0
and '1' anymore...
Patch attached. I'm not sure whether this zero is used elsewhere...
and BTW, what is it useful for?

New submission from Luke Kenneth Casson Leighton <lkcl at lkcl.net>:
this is reopening http://bugs.python.org/issue4977 because it was closed
without asking whether there was any further information or anything
else that required investigation.
there is no way for me to reopen the bug so i am forced to open a
new one.
mark - don't do that again, please.
the suggestion to use PyOS_strtol was a good one: you should have
left the bug as-is after that suggestion, and WAITED until i had
tested that.
the bug involves 64-bit zip files.
the fact that a 32-bit int is being returned, as -4932893211 (whatever)
instead of 44951 (whatever) is causing the problem.
so will you be kind enough and courteous enough to wait until
i have provided full information and investigated this issue?
or do you not want me to bother?

http://codereview.appspot.com/12470/diff/1/2#newcode1055
Line 1055: # b is an iterable of ints, it won't always support len().
There is no reason for write() to accept arbitrary iterable of ints,
only bytes-like and buffer-like objects. It will make the code simpler.
http://codereview.appspot.com/12470/diff/1/2#newcode1060
Line 1060: # No buffer API? Make intermediate slice copies instead.
Objects without the buffer API shouldn't be supported at all.

http://codereview.appspot.com/12470/diff/1/2#newcode1070
Line 1070: written += e.characters_written
e.characters_written can include bytes which were already part of the

should only count those bytes which were part of the object passed to
write().

New submission from Fons Dijkstra <fdij at xs4all.nl>:
When you set the delay parameter of the
logging.handlers.RotatingFileHandler.__init__() function to True, two
things go wrong:
1) A previously set formatter is reset (to None) upon lazy creating the
StreamHandler. That means in practice that you always will have the
default formatter which just formats the message.
2) Upon a roll-over, the delay parm does not seem to be used anymore as,
even if there are no records to log, the new current logfile is always
created.

The datastructures section of the tutorial states with respect to
"sequence unpacking" that "there is a small bit of asymmetry here: packing
multiple values always creates a tuple, and unpacking works for any
sequence". This is too general, as shown by the definition of assignment
statement target in the simple_stmts section of the reference shows:
tuples and lists are the only kinds of sequences that can appear on the
left-hand side of an assignment statement.

manifest

New submission from Robin Dunn <robin at alldunn.com>:
This may have already been discussed but my searches didn't turn up
anything concrete other than issue 4120 which is a similar but different
problem. The problem I'm facing is that wxPython requires that version
6 of the common controls DLL be loaded in order for the GUI applications
to use the themed version of the widgets on XP+ platforms, but it
appears that this can only be done reliably if the manifest for the .exe
is the one that specifies that version of the common controls assembly.
Prior to 2.6 I was able to install python[w].exe.manifest files next to
the python executables from my installer and it would work fine, but now
that Python 2.6 is built with MSVC9 and it has its own manifest that
does not always work. Initial testing seems to indicate that using an
external manifest still works ok on 32-bit platforms, but not on the
64-bit versions of Windows.
I've tried ensuring that the wxPython .pyd's and the wxWidgets DLLs have
an internal manifest that specifies the common controls assembly but
that has not helped. The only thing I've been able to find that works
for both 32 and 64 bit is to replace the internal manifest in python.exe
with a new one that specifies both the CRT and the Common Controls
assemblies, but that is obviously a Bad Thing for the install of an
extension module to do, so I'm opening this issue to look for alternatives.
So, does anybody have any experience or ideas on how to enable the
wxPython extensions to load the new common controls assembly without
needing to change the stock Python executables' manifest? If not, are
there any objections to adding the common controls assembly to the stock
manifest used for python.exe and pythonw.exe?

This file fails when run with doctest.testfile::
>>> print __name__
__builtin__
>>> print globals()['__name__'] # fails with KeyError: __name__
__builtin__
"__builtin__" is probably not a good value, but more importantly, this
means that you can't use namedtuples in text file doctests, since
namedtuple() inspects the calling frame::
>>> from namedtuple import namedtuple
>>> t = namedtuple('fred', 'x') # fails
(I presume this is the same for "from collections import namedtuple",
but I've not tested with 2.6+.)
A workaround is to add this line at the start of the test::
>>> __name__ = 'test'

Execution of "make test" for Python 2.6.1 halts with a segmentation
fault on line 2198 of Python-2.6.1/Lib/test/test_datetime.py; also
occurs using the attached script, narrowing it down to the %z sequence
in the format argument to datetime.time.strftime(), but only when the
time object has a non-None tzinfo. The segfault disappears when I
comment out line 1133 of Python-2.6.1/Modules/datetimemodule.c:
PyOS_snprintf(buf, buflen, "%c%02d%s%02d", sign, hours, sep, minutes);
Compiled with GCC 3.4.3 with Smashing Stack Protector on LFS 5.1.1
(Linux 2.6.11.12 and glibc 2.3.5 with ssp patches). Using BASECFLAGS=-
fno-stack-protector has no effect on the segfault. All other Python
tests pass. HAVE_SNPRINTF has been defined to 1 in pyconfig.h by the
config script.
I have not yet compiled gdb, but I can if requested.

New submission from Mark Dickinson <dickinsm at gmail.com>:
I just got a one-off, non-reproducible test_kqueue failure, during a 'make
test' of the trunk, on OS X 10.5.6. Here's the output:
test_kqueue
test test_kqueue failed -- Traceback (most recent call last):
File "/Users/dickinsm/python_source/trunk/Lib/test/test_kqueue.py", line
136, in test_queue_event
(server.fileno(), select.KQ_FILTER_READ, flags)])
AssertionError: [(5L, -2, 5L), (6L, -2, 5L), (6L, -1, 5L)] != [(5, -2, 5),
(5, -1, 5), (6, -2, 5), (6, -1, 5)]
Looking at the test_queue.py file just before line 136, I see:
events = kq.control(None, 4, 1)
# We may need to call it several times
for i in range(5):
if len(events) == 4:
break
events = kq.control(None, 4, 1)
Would adding a time.sleep(1.0) to the for loop make this test more robust?
My first impression was that the '1' in 'kq.control(None, 4, 1)' already
did this; i.e., that it meant that the kq.control function would wait up
to 1 second for a response, but that doesn't seem to be true. I tried
replacing the 1 with 1000000 and the test still runs nearly
instantaneously, even in the case where the kq.control call doesn't get 4
events first time around.
Out of curiosity, *why* is there a need to call this several times? I
fully believe there *is* such a need; I just don't know what it is.
Something to do with waiting for the socket send calls to complete, I
assume?

Subject: [New-bugs-announce] [issue5027] xml namespace not understood by
xml.sax.saxutils.XMLGenerator
In-Reply-To: <1232571582.02.0.360824752482.issue5027@psf.upfronthosting.co.za>
Message-ID: <1232571582.02.0.360824752482.issue5027@psf.upfronthosting.co.za>
New submission from Soren Roug <soren.roug at eea.europa.eu>:
The 'xml' namespace in XML files is special in that it need not be
declared. When xml.sax.saxutils.XMLGenerator is used with the namespace
feature it does not know how to handle it.
Example. The code:
import xml.sax, xml.sax.saxutils
parser = xml.sax.make_parser()
parser.setFeature(xml.sax.handler.feature_namespaces, 1)
c = xml.sax.saxutils.XMLGenerator()
parser.setContentHandler(c)
parser.parse('testfile.xml')
executed on the testfile.xml with this content:
<?xml version="1.0"?>
<a:greetings xmlns:a="http://example.com/ns">
<a:greet xml:lang="en">Hello world</a:greet>
</a:greetings>
will produce this error:
...
File "/usr/lib/python2.5/xml/sax/saxutils.py", line 149, in startElementNS
self._write(' %s=%s' % (self._qname(name), quoteattr(value)))
File "/usr/lib/python2.5/xml/sax/saxutils.py", line 107, in _qname
prefix = self._current_context[name[0]]
KeyError: u'http://www.w3.org/XML/1998/namespace'
It can be fixed by making an exception for the xml namespace (as
required by W3C - See http://www.w3.org/XML/1998/namespace) in
xml/sax/saxutils.py. The _qname method could then look like this:
def _qname(self, name):
"""Builds a qualified name from a (ns_url, localname) pair"""
if name[0]:
if name[0] == u'http://www.w3.org/XML/1998/namespace':
return u'xml' + ":" + name[1]
# The name is in a non-empty namespace
prefix = self._current_context[name[0]]
if prefix:
# If it is not the default namespace, prepend the prefix
return prefix + ":" + name[1]
# Return the unqualified name
return name[1]

Subject: [New-bugs-announce] [issue5028] tokenize.generate_tokens doesn't
always return logical line
In-Reply-To: <1232588343.15.0.723713394492.issue5028@psf.upfronthosting.co.za>
Message-ID: <1232588343.15.0.723713394492.issue5028@psf.upfronthosting.co.za>
New submission from Duncan Findlay <duncf at apache.org>:
According to the documentation for tokenize.generate_tokens:
"The generator produces 5-tuples with these members: the token type; the
token string; a 2-tuple (srow, scol) of ints specifying the row and
column where the token begins in the source; a 2-tuple (erow, ecol) of
ints specifying the row and column where the token ends in the source;
and the line on which the token was found. The line passed (the last
tuple item) is the logical line; continuation lines are included."
It seems though that the "logical line" -- the last element of the tuple
is the physical line unless the token being returned spans beyond the
end of the line. As an example, consider a test file test.py:
foo = """
%s """ % 'bar'
>>> import pprint, tokenize
>>> pprint.pprint(list(tokenize.generate_tokens(open('test.py').readline)))
[(1, 'foo', (1, 0), (1, 3), 'foo = """\n'),
(51, '=', (1, 4), (1, 5), 'foo = """\n'),
(3, '"""\n%s """', (1, 6), (2, 6), 'foo = """\n%s """ % \'bar\'\n'),
(51, '%', (2, 7), (2, 8), '%s """ % \'bar\'\n'),
(3, "'bar'", (2, 9), (2, 14), '%s """ % \'bar\'\n'),
(4, '\n', (2, 14), (2, 15), '%s """ % \'bar\'\n'),
(0, '', (3, 0), (3, 0), '')]
>>>
Since there is only one logical line, I would expect the first 6 tokens
to have the same 5th element.

In the threading module the Thread.daemon documentation says:
"The thread?s daemon flag. This must be set before start() is called,
otherwise RuntimeError is raised.
The initial value is inherited from the creating thread.
The entire Python program exits when no alive non-daemon threads are
left."
I think the docs should state Thread.daemon's type (boolean, or integer,
or something else?) and its default value (when you have not set .daemon
in the creating thread.)

('range' and 'count' are very similar - 'count' could even be merged into
'range', for example by making 'range(None)' equivalent to 'count()')

Calling the unicode function on a proxy object, doesn't use the proxi-ed

Message-ID: <1232730438.9.0.904675957675.issue5038@psf.upfronthosting.co.za>
New submission from jan matejek <jmatejek at suse.cz>:
since 2.6 httplib supports reading from file-like objects.
Now consider the following situation:
There are two handlers in urrlib2, first is plain http, second is basic
auth.
I want to POST a file to a service, and pass the open file object as
data parameter to urllib2.urlopen.
First handler is invoked, it sends the file data, but gets 401
Unauthorized return code and fails with that.
Second handler in chain is invoked (at least that's how i understand
urrlib2, please correct me if i'm talking rubbish). At that point the
open file is at EOF, so empty data is sent.
furthermore, the obvious solution "you can't do this through urllib so
go read the file yourself" doesn't apply that well - the file object in
question is actually a mmap.mmap instance.
This code is in production since python 2.4. Until file object support
in httplib was introduced, it worked fine, handling the mmap'ed file as
a string. Now it is picked up as read()-able and this problem occurs.
Only workaround to restore pre-2.6 behavior that comes to mind is
building a wrapper class for the mmap object that hides its read() method.

New submission from Terry J. Reedy <tjreedy at udel.edu>:
Language / Data model / Objects, values and types (2.6-3.1)
third paragraph, has the following note:
"(Implementation note: the current implementation uses a
reference-counting scheme with (optional) delayed detection of
cyclically linked garbage, which collects most objects as soon as they
become unreachable, but is not guaranteed to collect garbage containing
circular references. See the documentation of the gc module for
information on controlling the collection of cyclic garbage.)"
There are two issues here: there are now other implementations that act
differently; CPython may change (as GvR reiterated strongly today in the
PyDev thread "__del__ and tp_dealloc in the IO lib", in response to a
request that the current behavior be defined and documented as not
permanent). So I suggest:
change 'the current implementation' to 'CPython currently'
add "Other implementations act differently and CPython may change." (at
the end)

In-Reply-To: <1232792394.35.0.81811153867.issue5040@psf.upfronthosting.co.za>
Message-ID: <1232792394.35.0.81811153867.issue5040@psf.upfronthosting.co.za>
New submission from Wayne Huang <WayneHuang.public at gmail.com>:
I met a bug of CGIXMLRPCRequestHandler in Python3.0. Because of the bug,
I couldn't use RPC in Apache CGI.
The version of my Python 3.0 is "Python 3.0 (r30:67507, Dec 3 2008,
20:14:27) [MSC v.1500 32 bit (Intel)] win32".
The code of my client is follow.
s = xmlrpc.client.ServerProxy('http://localhost/cgi-bin/rpc.py')
print(s.system.listMethods())
The code of my server in Apache's cgi-bin is follow
#!C:/Python30/python.exe
from xmlrpc.server import *
handler=CGIXMLRPCRequestHandler()
handler.register_introspection_functions()
handler.handle_request()
When I run the client code,some error of parser raise.
I found it is the matter of 'Content-Length' in the HTTP Response of
CGIXMLRPCRequestHandler,it is a wrong number.

New submission from Jason R. Coombs <jaraco at jaraco.com>:
When trying to create a sub-subclass of a ctypes.Structure, the behavior
is not as expected.
An executable example that describes the problem in detail and
demonstrates the issue is available at
http://paste.turbogears.org/paste/29555 and also attached.
The failing behavior is near the beginning, following the description.
Three unsuccessful workarounds follow.
The expected behavior is found at the end, where a final workaround has
been implemented.
Can this behavior be improved in subsequent releases of ctypes? If not,
can ctypes at least support the workaround natively (perhaps by
providing a method in the Structure class that performs the workaround
and can be called by a sub-subclass during __init__)?

literal strings
In-Reply-To: <1232831861.1.0.505003833235.issue5045@psf.upfronthosting.co.za>
Message-ID: <1232831861.1.0.505003833235.issue5045@psf.upfronthosting.co.za>
New submission from Branden Moore <bmoore-python at forkit.org>:
IMAP Literals are a tricky subject. Currently, if IMAP returns:
* text text text {5}\r\n
12345more text
imaplib will return 2 data items:
[("text text text {5}", '12345'), "more text"]
This forces users of imaplib to then parse out and remove the '{5}' from
the first part of the tuple before appending the literal string. It
would be nice to have imaplib strip the '{size}' portion of the string
in the first part of the tuple, so that the return value would be:
[("text text text ", '12345'), "more text"]
Though, because this entire response from the IMAP server should be
interpreted as a single line, it would be even better to return a
response such that 'data' is:
[(("text text text ", '12345'), "more text")]
a.k.a., a single 'data' item (only one IMAP response per data item) that
contains either a string or a tuple. The tuple will contain either more
tuples and/or more strings. Each sub-tuple here would contain two
strings, text, and the IMAP Literal String.
This would make parsing the responses from imaplib much more simple. It
demarks obviously where IMAP Literal Strings are, and doesn't require
additional string parsing on the side of the imaplib user.
Thanks!

New submission from Luke Kenneth Casson Leighton <lkcl at lkcl.net>:
this is an update of the mingw+msys port for native win32,
with the aim of being both compiled and used under both
wine-win32 and native-win32.
it is not a cross-compile patch. it does not require -lwine.
it does not require a unix system. it does not require cygwin.
(repeat the previous four sentences for both build _and_ use
of the resultant python.exe). this information is specifically
given and stated [so blandly] because several people have been
extremely confused by what this patch achieves, due to the
tools being utilised to achieve it [wine].
the patch is against svn trunk r68884.
as of 2 hours ago, the following tests failed:
22 tests failed:
test_cmath test_cmd_line_script test_compiler test_ctypes
test_decimal test_distutils test_file test_logging test_mailbox
test_math test_ntpath test_os test_parser test_posixpath test_pwd
test_smtplib test_startfile test_tempfile test_transformer
test_winsound test_zipfile test_zipimport_support
since then, several have been corrected. test_pwd should not be
being tested. several of the tests (test_tempfile) are fails due
to use of native wine msvcrt (it gets better when win32 msvcrt
is used).
this is work-in-progress for those people interested.
builds with --enable-msvcr9build are possible.
incorporation of roumen's cross-compile work is ongoing.

operating system which died in 2000. Can't see why we need to support it.

New submission from Konrad <konryd at gmail.com>:
The function itertools.combinations might benefit from making
the 'r' (length of the combinations) argument optionally a sequence.
With that change one could call combinations(sequence, [2, 3]) in
order to get all combinations of length 2 and 3.
In particular, one could call combinations(sequence,
range(len(sequence)) in order to get *all* combinations of given
sequence.
The change would be backwards compatible as it would check for
sequential arguments.

New submission from Mike Watkins <python at mikewatkins.ca>:
HTTPMessage.getallmatchingheaders() stopped working sometime after
Python 3.0 release. In a recent (1 day ago) svn update the
implementation says the method was copied from rfc822.message; the
Python 3.x implementation is broken (iterates through self.keys instead
of header values). I've not looked back to see where the change was
introduced but I do know that it broke post 3.0 release.
But more importantly than the flaw in this method, the functionality is
duplicated elsewhere in Python 3.x.
I propose either deprecating getallmatchingheaders() or if it is to be
kept for compatibility, the fix can be simply replacing the method body
with:
self.get_all(name)
The docstring for get_all (defined in email.message) affirms that its
output is indeed compatible with that which was intended for
getallmatchingheaders().
get_all(self, name, failobj=None) method of client.HTTPMessage instance
Return a list of all the values for the named field.
These will be sorted in the order they appeared in the original
message, and may contain duplicates. Any fields deleted and
re-inserted are always appended to the header list.
If no such fields exist, failobj is returned (defaults to None).
I've tested the use of get_all against one web server (QP) which runs on
both Python 2.x and 3.x.
As a result of the broken getallmatchingheaders() the QP web server now
uses for the same purpose as getallmatchingheaders() instead:
get_all(name) (defined in email.message.Message in Py3k and
getheaders(name) (defined in rfc822.Message).

Subject: [New-bugs-announce] [issue5054] CGIHTTPRequestHandler.run_cgi()
HTTP_ACCEPT improperly parsed
In-Reply-To: <1232897403.01.0.0399148938595.issue5054@psf.upfronthosting.co.za>
Message-ID: <1232897403.01.0.0399148938595.issue5054@psf.upfronthosting.co.za>
New submission from Mike Watkins <python at mikewatkins.ca>:
There appears to have been a bug in how HTTP_ACCEPT is parsed living in
run_cgi() for eons, perhaps from the time it was written. Perhaps not
many are using this code (I'm not either) but recent (post 3.0 Release)
Python 3.x appear to have broken something in getallmatchingheaders()
(which originates in Message) and I happened to stumble upon this
condition while searching through the stdlib code.
>From Line 980 of http.server
accept = []
for line in self.headers.getallmatchingheaders('accept'):
if line[:1] in "\t\n\r ":
accept.append(line.strip())
else:
accept = accept + line[7:].split(',')
env['HTTP_ACCEPT'] = ','.join(accept)
line[:1] in '\t\n\r' clearly was meant to to be line[-1].
However that doesn't fix completely this chunk of code as it makes some
assumptions about what getallmatchingheaders() delivers which aren't
accurate. The following behaves as expected and feels safer:
accept = []
for line in self.headers.getallmatchingheaders('accept'):
if line.lower().startswith("accept:"):
line = line[7:]
for part in line.split(','):
part = part.strip()
if part:
accept.append(part)
env['HTTP_ACCEPT'] = ','.join(accept)
Note that post Python 3.0 release,
http.client.HTTPMessage.getallmatchingheaders() was broken. I've
reported this just now and proposed a fix in #5053.

an assumption has been made in the python core api that all operating
systems "dynamic module loading" can access data segments. windows
_cannot_ do this.
the "workaround" has been to statically link absolutely _everything_
into a single whopping great dll.
the proper solution is to provide "accesser" functions:
PyAPI_FUNC(PyObject *)
PyErr_GetPyExc_OSError(void)
{
return (PyObject*)PyExc_OSError;
}
PyAPI_FUNC(char*) _PyStructSequence_Get_UnnamedField(void)
{
return PyStructSequence_UnnamedField;
}
... actually the _best_ solution is to have everything that's needed in
a vector-table [discussed on python-dev mailing list]

optimization leads to non-portable pyc file

New submission from Antoine Pitrou <pitrou at free.fr>:
The peephole optimizer can optimize indexed access to an unicode
constant which does not give the same result in UCS-2 and UCS-4 builds.
As a result, the pyc file is not portable across those builds.
This is something I witnessed when recompiling in UCS-2 rather than
UCS-4 mode, and having a strange failure in test_multibytecodec. Erasing
test_multibytecodec.pyc suppressed the failure.
Here is a small demonstration of the problem:
>>> def f():
... return '\U00012345'[0]
...
>>> import dis
>>> dis.dis(f)
2 0 LOAD_CONST 3 ('\ud808')
3 RETURN_VALUE
For reference, here is the error I had in test_multibytecodec:
======================================================================
FAIL: test_gb18030 (test.test_multibytecodec.Test_StreamWriter)

New submission from Mitchell Model <mlm at acm.org>:
Documentation of the mode parameter of the built-in function open is
insufficient with respect to what values are acceptable.
(1) Right after the mode table, it states "For binary random access, the
mode 'w+b' opens and truncates the file to 0 bytes, while 'r+b' opens
the file without truncation." This is true of text random access too --
w+ or r+. Furthermore, the possibility of a+, while meaningful, is not
mentioned.
(2) The documentation does not, but should, say that while w/r/a with or
without the plus can appear without a 'b' or 't', a plain 'b' as the
mode valuable raises an error that r/w/a wasn't specified.
(3) The documentation does not, but should, say that + cannot stand on
its own -- the mode must also include an r, w, or a. The table listing
the meanings of each value just says + means "open a disk file for
updating (reading and writing)". Suggested rewording is to put the
phrase "in conjunction with 'r', 'w', or 'a', open a disk file...".
Alternatively, add a note to that table entry and explain below that the
plus must accompany a r/w/a.

New submission from Carl Johnson <carl at carlsensei.com>:
The documentation at http://docs.python.org/library/rlcompleter.html
claims that
Completer.complete(text, state)?
Return the state*th completion for *text.
If called for text that doesn?t include a period character ('.'), it
will complete from names currently defined in __main__, __builtin__ and
keywords (as defined by the keyword module).
If called for a dotted name, it will try to evaluate anything without
obvious side-effects (functions will not be evaluated, but it can
generate calls to __getattr__()) up to the last part, and find matches
for the rest via the dir() function. Any exception raised during the
evaluation of the expression is caught, silenced and None is returned.
In other words, it claims to use dir(obj) as part of the tab completion
process. This is not true (using Python 2.6.1 on OS X):
>>> class B(object):
... def __dir__(self): return dir(u"") #Makes B objects look like strings

New submission from Jean-Paul Calderone <exarkun at divmod.com>:
Sometimes a syntax error in source passed to `compiler.parse? causes a
`SyntaxError? with lots of nice information to be raised:
>>> from compiler import parse
>>> try:
... parse("def f(")
... except SyntaxError, e:
... pass
...
>>> e
SyntaxError('unexpected EOF while parsing', (None, 1, 6, 'def f('))
But for other syntax errors, only a string message is provided, no
location information:
>>> try:
... parse("def f(x=10, y): pass")
... except SyntaxError, f:
... pass
...
>>> f
SyntaxError('non-default argument follows default argument',)
>>> try:
... parse("f(x=10, y)")
... except SyntaxError, g:
... pass
...
>>> g
SyntaxError('non-keyword arg after keyword arg',)
>>>
On the other hand, the built in compiler produces exceptions which do
have this information in these cases.
The absence of the information makes the job of tools trying to operate
on Python source code more difficult (naively written, they'll simply
fail when they encounter one of these less informative exceptions).

subprocess or personal firewall software is blocking the connection."
This should report what needs to be opened on the firewall to allow
the connection, e.g. "Allow UDP/TCP connections to 127.0.0.1 on ports
FOO and BAR and try again".

New submission from Steven D'Aprano <steve at pearwood.info>:
Documentation for IDLE states:
Starting IDLE on UNIX
On Unix, just type "idle" at a command prompt. This should bring
up a Window similar to the one above. (If it doesn't, look for
the "idle" script in the Tools/idle directory in the Python source
distribution.)
http://www.python.org/idle/doc/idlemain.html
I believe that is obsolete, I cannot see a Tools/idle directory in
either 2.5 or 2.6. Perhaps better instructions might be:
(If it doesn't, run "python LOC/idlelib/idle.py" where LOC
is the location of your Python source distribution, usually
/usr/lib/python*.)
or similar.

New submission from Andy Buckley <andy at insectnation.org>:
If you attempt to call "python setup.py install --prefix=/foo", and
/foo/lib/pythonX.Y/site-packages does not exist, the installation will
fail, requiring that the directory be made by hand.
Since there is no easy way to know in advance (other than by running
Python to build the version number string) exactly where the install
will go, this can be troublesome for automated build scripts. For this
reason, and also to be more consistent with existing build/install
systems like autotools, I suggest that distutils builds the necessary
portions of the lib directory tree (provided /foo exists). This should
certainly happen (IMHO) if the --force option is given.

New submission from Andy Buckley <andy at insectnation.org>:
At present, distutils exits with an error return code if the directory
that modules are being installed into is not in PYTHONPATH. Since the
install path is not easily obtained (it at least requires running Python
to work out the version string, plus some guesswork about "lib" vs.
"lib64", etc. etc.), it would be nice if this was not a blocking
problem... at least when the --force flag is passed to setup.py
(PS. It would be nice if there *is* a way to get the installation path
from distutils before installing, for the reasons mentioned: that way
automatic install scripts like the one I'm managing could work out the
path, make it and add it to the PYTHONPATH, without worrying about
getting it wrong. Am I just missing something that already exists?)

GET command instead of local path

New submission from Olemis Lang <olemis at gmail.com>:
Hello ...
The first thing I have to say is that I searched the open issues and I
found nothing similar to what I am going to report hereinafter. If this
ticket is duplicate , I apologize ...
Yesterday I was testing how to access the wiki pages in a
Trac [1]_ site and I realized that something wrong was happening
(a bug? ...)
Initially the behavior was as follows :
{{{
#!python
>>> u = urllib.urlopen('http://localhost:8000/trac-dev')
>>> u.read()
'Environment not found'
>>> u.close()
}}}
And tracd reported a line like this
{{{
127.0.0.1 - - [25/Jan/2009 17:32:08] "GET http://localhost:8000/trac-
dev HTTP/1.0" 404 -
}}}
Which means that a 'Not found' error code was sent back to urllib
client.
I tried to access the same page from my browser and tracd reported
{{{
127.0.0.1 - - [25/Jan/2009 18:05:44] "GET /trac-dev HTTP/1.0" 200 -
}}}
The problem is obvious ... urllib was sending the full URL after GET
and it should send only the string after the network location.
I applied the following patch to urllib (yours will be better, I am
sure about that ;)
{{{

}}}
The same picture is shown when using both Python 2.5.1 and 2.5.2 ...
I have not installed Python 2.6.x so I am not sure about whether this
issue has propagated onto newer versions of Python ... and I don't
know euther if this issue is also present in urllib2 or not ...
... so further research is needed, but IMO this is a serious bug :(
PD: If this is a bug ... how could it be hidden so far ? Is there any
test case written to assert this kind of things ? I checked out
`test.test_urllib` and `test.test_urllibnet` modules and I saw
nothing at all ...

New submission from Mark Hammond <mhammond at users.sourceforge.net>:
After consideration of issue 4120 and issue 4566, it seems to me that
executables created by bdist_wininst will have a manifest referencing
the MSVC9 assembly, and thus will be in a similar position to the .pyd
files in issue 4120 - that unless the assembly is installed globally or
next to the executable itself, the executable will not start. Note that
I have not verified this, but have verified the final installer
executable references the CRT assembly, and given those other bugs,
expect it to be true.
It seems to me a reasonable solution would be to have the bdist_wininst
stub use a static copy of the C runtime library. While this means 2
copies of the CRT will eventually be loaded and would otherwise be
considered evil, the way the stub dynamically loads Python and the few
API functions it uses means it might be reasonable in this case. Would
the trivial patch which achieves this be desired?

New submission from Mark Hammond <mhammond at users.sourceforge.net>:
bdist_wininst installers created by py3k fail due to PySys_SetArgv and
Py_SetProgramName both being passed 'char *' strings instead of wide
strings.
The patch is against the svn trunk as currently Python 2.x and 3.x share
the same bdist_wininst stub. The patch doesn't change the behaviour on
Python 2.x, and continues to allow the same executable stub to be
shared, as the appropriate signature is determined at runtime based on
the Python version.
The patch does not include the 2 new stub executables required
(wininst-9.0.exe and wininst-9.0-amd64.exe), but the patch *and* the new
stub executables should be merged into whatever py3k branches are
appropriate. I've tested (pywin32) installers based on the new stub on
python 2.6 32bit, and python 3.0 32 and 64bit.

The docs for time.ctime() (quoted below) seem to have been copied from
time.asctime(). They refer to a time tuple and localtime(), where they
should refer to seconds and time().
Current docs::
ctime(seconds) -> string
Convert a time in seconds since the Epoch to a string in local time.
This is equivalent to asctime(localtime(seconds)). When the time
tuple is not present, current time as returned by localtime() is
used.

Subject: [New-bugs-announce] [issue5080] PyArg_Parse* should raise TypeError
for float parsed with integer format

Message-ID: <1233059037.74.0.384834765102.issue5080@psf.upfronthosting.co.za>
New submission from Mark Dickinson <dickinsm at gmail.com>:
Since Python 2.3, PyArg_ParseTuple and friends give a DeprecationWarning
for floating-point arguments where integers are expected. From
http://www.python.org/download/releases/2.3/NEWS.txt:
- The PyArg_Parse functions now issue a DeprecationWarning if a float
argument is provided when an integer is specified (this affects the 'b',
'B', 'h', 'H', 'i', and 'l' codes). Future versions of Python will
raise a TypeError.
Can we turn that DeprecationWarning into a TypeError for 2.7? (It's
already a TypeError in 3.x.) I'd like to see things like 'range(-0.3)'
and 'itertools.combinations(range(3), 5.1)' raise TypeError.
N.B. The relevant format codes in 2.7 include 'I' and 'n' in addition to
the six codes listed above.

New submission from Andrea Corbellini <andrea.corbellini at beeseek.org>:
Most of the Python frameworks have some functions and classes that are
widely used. For example a 'log.debug' function will be used in almost
all modules. It is inconvenient to write 'import log' every time.
It would be useful to have a special place (a dict or a special module)
where you can declare attributes that can be used everywhere without
importing anything. Currently, the only way to do this is:
>>> import __builtin__
>>> __builtin__.debug = log.debug
However, I think that this shouldn't be the better solution. Using
something like '__framework__' would be really better, in my opinion.

Subject: [New-bugs-announce] [issue5084] unpickling does not intern
attribute names
In-Reply-To: <1233093140.55.0.0122548653801.issue5084@psf.upfronthosting.co.za>
Message-ID: <1233093140.55.0.0122548653801.issue5084@psf.upfronthosting.co.za>
New submission from Jake McGuire <jake at youtube.com>:
Instance attribute names are normally interned - this is done in
PyObject_SetAttr (among other places). Unpickling (in pickle and
cPickle) directly updates __dict__ on the instance object. This
bypasses the interning so you end up with many copies of the strings
representing your attribute names, which wastes a lot of space, both in
RAM and in pickles of sequences of objects created from pickles. Note
that the native python memcached client uses pickle to serialize
objects.
>>> import pickle
>>> class C(object):
... def __init__(self, x):
... self.long_attribute_name = x
...
>>> len(pickle.dumps([pickle.loads(pickle.dumps(C(None),
pickle.HIGHEST_PROTOCOL)) for i in range(100)],
pickle.HIGHEST_PROTOCOL))
3658
>>> len(pickle.dumps([C(None) for i in range(100)],
pickle.HIGHEST_PROTOCOL))
1441
>>>
Interning the strings on unpickling makes the pickles smaller, and at
least for cPickle actually makes unpickling sequences of many objects
slightly faster. I have included proposed patches to cPickle.c and
pickle.py, and would appreciate any feedback.

This can be fixed if replace

spawn(['tar', '--help'])
but, "tar --help" outputs very long message, it is not beautiful.
So I'll push attached patch. (This also checks gzip

New submission from Fons Dijkstra <fdij at xs4all.nl>:
Although it is possible to specify a default value for an append action,
either directly or through the set_default() function, it is not handled
correctly when this default is overruled by the user. Take for example
the following code:
import optparse
parser = optparse.OptionParser()
parser.add_option("-o", "--option", action = "append")
parser.set_defaults(option = ["a"])
options, args = parser.parse_args()
print options
When this is called without arguments the following is printed:
{'option': ['a']} # as expected
But when it is called with for example with -ob the following is
printed:
{'option': ['a', 'b']} # expected {'option': ['b']}
So the default option is also appended, even if the option is explicitly defined by the user.

I assume that there's a genuine exception here that we're not seeing;
i.e., that there's a shallow error (tuple instead of exception) that's
masking output of information from a deeper error.

New submission from Christian Heimes <lists at cheimes.de>:
One of our application recently started to segfault in
PyObject_Malloc(). The cause of the problem could be tracked down to an
overflowing internal cache.
However I was astonished that Python was segfaulting instead of raising
a memory exception. I did some post mortem debugging with gdb and found
an address out of bounds problem. I think the issue is caused by the
limited heap of a 32bit Python process.

Subject: [New-bugs-announce] [issue5092] weird memory usage in
multiprocessing module
In-Reply-To: <1233188020.97.0.306560555097.issue5092@psf.upfronthosting.co.za>

New submission from Jerzy <jerzyo at genesilico.pl>:
Hi
I am using the multiprocessing mudule and I found a very weird thing.
It seems that that the result of one fragment of the code depends on the
fragment of the code that is after it, which should not happen.
My script looks like this
import time
import multiprocessing
import sys
def f():
sys.stderr.write(str(len(l))+"\n")
print len(l)
#del l
while(True):
time.sleep(1)
l=[]
for i in range(2*1000*1000):
l.append(str(i))
process = multiprocessing.Process(target=f)
process.start()
while(True):
time.sleep(1)
And its output is as expected:
2000000
2000000
but when I uncoment the 'del l' line I get:
File
"/home/jerzyo/programs/python2.6/Python-2.6.1/Lib/multiprocessing/process.py",
line 231, in _bootstrap
self.run()
File
"/home/jerzyo/programs/python2.6/Python-2.6.1/Lib/multiprocessing/process.py",
line 88, in run
self._target(*self._args, **self._kwargs)
File "bin/momory.py", line 6, in f
sys.stderr.write(str(len(l))+"\n")
UnboundLocalError: local variable 'l' referenced before assignment
How is that? The line that deletes l is after the printing line. How
python interpreter knows that l will be deleted. This is a very anomalus
behaviour and should never happen.
By the way. Is there any way to free some parts of memory in child
process. Suppose I wand to create 100 child processes that do not use
the l list. How can I avoid making 100 copies of l in child processes.
That is my firs post and won't come here very often, so please answer
also to my email (if it is not automaic). I am running python 2.6.1 on
ubuntu 8.04 32bit.

New submission from STINNER Victor <victor.stinner at haypocalc.com>:
If Python output is redirected to a pipe, sys.stdout encoding is
ASCII. So "2to3 script.py|cat" will write the patch in ASCII. If the
script contains a non-ASCII character, 2to3 fails with:
...
File ".../lib2to3/refactor.py", line 238, in refactor_file
self.processed_file(str(tree)[:-1], filename, write=write)
File ".../lib2to3/refactor.py", line 342, in processed_file
self.print_output(diff_texts(old_text, new_text, filename))
File ".../main.py", line 48, in print_output
print(line)
UnicodeEncodeError: 'ascii' codec can't encode character '\xfb' in
position 11: ordinal not in range(128)
Should we consider the input file and stdout as binary files?
Workaround: modify the files in place (-w option) but don't write the
patch to stdout (no such option yet).
A project may contain scripts in ASCII, Latin-1 and UTF-8 (eg. Python
source code ;-)).

New submission from Brett Cannon <brett at python.org>:
When you call datetime.datetime.utcnow() you get back a naive datetime
object. But why? You asked for UTC as the timezone based on what method
call you made. And UTC is a very concrete timezone that never changes.
It would be nice to have a concrete UTC tzinfo class that utcnow() uses
so that at least those datetime instances are non-naive.
If people have no issues with making this happen I will write the code
for the concrete UTC tzinfo instance and make the appropriate changes to
utcnow().

[C:\]echo %ProgramFiles%
C:\Program Files
This 'half' escapping seems odd, and is annoying when building file

Exception exceptions.AttributeError: "'NoneType' object has no attribute

which I tracked down to the os module being set to None (yes really!) in
POpen._internal_poll() when called from Popen.__del__, so this line:

was generating the error.
I guess that the module is getting unloaded earlier somehow (maybe a
race condition)?

New submission from Jeroen Dirks <jeroen.dirks at oracle.com>:
I am using cElementTree.iterparse in order to parse through a huge XML
document and filter out sections of interest.
The usage pattern is that I wait for an "end" event for a element of
interest and then if it matches a some criterium I write it out using
cElementTree.tostring().
My code had bug in it because the cElementTree.tostring methods prints
the element including its tail. The element retreived from the iterparse
iterator sometimes contains the tail by the time it emits the end event
but sometimes it does not.
In my document the tail just consisted of the newline '\n' character and
about 98% of the time it was attached to the element during its end event.
This is rather confusing behavior.
Could ElementTree/cElementTree.iterparse be changed so that if you
respond to the end event for an element its tail is never set?

New submission from Jacques Grove <jacques at tripitinc.com>:
When doing a urllib2 fetch of a url that results in a redirect, the
connection to the redirect does not pass along the timeout of the
original url opener. The result is that the redirected url fetch (which
is a new request) will get the default socket timeout, instead of the
timeout that the user requested originally. This is obviously a bug.
So we have in urllib2.py in 2.6.1:
def http_error_302(self, req, fp, code, msg, headers):
.....
return self.parent.open(new)
this should be:
return self.parent.open(new, timeout=req.timeout)
or something in that vein.
Of course, to be 100% correct, you should probably keep track of how
much time has elapsed since the original url fetch went out, and reduce
the timeout based on this, but I'm not asking for miracles :-)

New submission from Jacques Grove <jacques at tripitinc.com>:
In ssl.py of Python 2.6.1 we have this code in SSLSocket.__init__():
if do_handshake_on_connect:
timeout = self.gettimeout()
try:
self.settimeout(None)
self.do_handshake()
finally:
self.settimeout(timeout)
The problem is, what happens if the remote end (server) is hanging when
do_handshake() is called? The result is that the user-requested timeout
will be ignored, and the connection will hang until the TCP socket
timeout expires.
This is easily reproducable with this test code:
import urllib2
urllib2.urlopen("https://localhost:9000/", timeout=2.0)
and running netcat on port 9000, i.e.:
nc -l -p 9000 localhost
If you use "http" instead of "https", the timeout works as expected
(after 2 seconds in this case).

New submission from Brandon Adams <sockonafish at gmail.com>:
When using sqlite3.Row as the row_factory for a sqlite3 connection and
performing a SQL join that returns rows from two or more tables with
identical column names, the returned sqlite3.Row object contains
duplicate keys. Subsequently, when trying to access values by key, only
the value contained in the lowest numbered index matching the key is
returned. Additionally, attempting to use the keys returned to create a
new table in the database fails due to a duplicate column name error.
A better behavior would be for the sqlite3.Row object's indices to be
prefixed with table names for cases in which a query produces results
from two or more tables.

just before example that does not work,
class A:
a = 42
b = list(a + i for i in range(10))
says :
"The scope of names defined in a class block is limited to the class
block; it does not extend to the code blocks of methods ? this includes
generator expressions since they are implemented using a function scope."
As pointed out by Alan Isaacs (clp), in 3.0,
"this includes comprehensions and generator expressions"
would be more complete and not possibly imply that g.e.s are special in
this regard. In 2.x,
c = [a + i for i in range(10)]
works but it fails with same
"NameError: global name 'a' is not defined"
in 3.0. In fact, I think 'comprehensions and ' should be added just
because this is a change which people could trip over.

New submission from John Machin <sjmachin at users.sourceforge.net>:
Docs say """The default encoding is platform dependent""" but don't say
how to find out what that is, or how it is determined. On my Windows XP
SP3 setup, the default is cp1252, but the best/only guess at finding out
without actually opening a file involved sys.defaultencoding() which
produces 'utf-8'. I was pointed at locale.getpreferredencoding(), which
returns 'cp1252' on my machine.
Please add a sentence along these lines: The default encoding is
(obtained by calling|the same as) locale.getpreferredencoding(), not
sys.getdefaultencoding() -- corrected/amplified as necessary.

PyUnicode_FromFormatV()

Message-ID: <1233314818.25.0.50797871273.issue5108@psf.upfronthosting.co.za>
New submission from STINNER Victor <victor.stinner at haypocalc.com>:
PyUnicode_FromFormatV() doesn't count correctly the unicode length of
an UTF-8 string. Commit r57837 "Change %s argument for
PyUnicode_FromFormat to be UTF-8. Fixes #1070." introduced the bug. To
compute the length, it uses a a complex code to compute the length of
the UTF-8 string, whereas PyUnicode_DecodeUTF8(p,
strlen(p), "replace") + Py_UNICODE_COPY() is used to copy the string.
The problem may comes from the error handling ("replace").
Valgrind show that the error occurs at Py_UNICODE_COPY(): Invalid
write of size 1. Since it's only one byte, Python does not always
crash.
To reproduce the crash, use PyUnicode_FromFormatV() or function using
it: PyUnicode_FromFormat(), PyErr_Format(), ...
Example 1:
import grp
x=["\uDBE7\u8C99", "\u9C31\uF8DC\u3EC5\u1804\u629D\uE748\u68C8\uCF74\u9E63\uF647\uBF7A\uED63"]
x=str(x)
grp.getgrnam(x)
Example 2:
import unicodedata
x
= "\\udbe7\u8c99', '\u9c31\\uf8dc\u3ec5\u1804\u629d\\ue748\u68c8\ucf74\u9e63\\uf647\ubf7a\\ued63"
unicodedata.lookup(x)
I wrote a patch reusing PyUnicode_DecodeUTF8(p, strlen(p), "replace")
+ PyUnicode_GET_SIZE() to get the real length of the converted UTF-8
string.
A better patch should reuse code used to convert UTF-8 to Unicode with
the "replace" error handling.

New submission from Malcolm Purvis <malcolm at purvis.id.au>:
Copying an array.array object via the array constructor is some 100x
slower than using slicing or even converting the array to a string and
then passing that string to the array constructor.
Running the attached program on a 2.2GHz MacBook Pro (OSX 10.5.5, 4GB
RAM) produces this output:
$ python2.6 array_test.py
Constructor: 18.5617749691
Slice: 0.169251918793
String: 0.375015974045
>From a look at arraymodule.c it seems that array_new() does not have a
special case for the array type and therefore uses the generic sequence
copy code rather than using memcpy(), like it can for slicing.

interpreter in a non-UTF8 terminal (Py3)
In-Reply-To: <1233329209.55.0.55287436123.issue5110@psf.upfronthosting.co.za>
Message-ID: <1233329209.55.0.55287436123.issue5110@psf.upfronthosting.co.za>
New submission from Ezio Melotti <ezio.melotti at gmail.com>:
In Py2.x
>>> u'\2620'
outputs u'\2620' whereas
>>> print u'\2620'
raises an error.
Instead, in Py3.x, both
>>> '\u2620'
and
>>> print('\u2620')
raise an error if the terminal doesn't use an encoding able to display
the character (e.g. the windows terminal used for these examples).
This is caused by the new string representation defined in the PEP3138[1].
Consider also the following example:
Py2:
>>> [u'\u2620']
[u'\u2620']
Py3:
>>> ['\u2620']
UnicodeEncodeError: 'charmap' codec can't encode character '\u2620' in
position 9: character maps to <undefined>
This means that there is no way to print lists (or other objects) that
contain characters that can't be encoded.
Two workarounds may be:
1) encode all the elements of the list, but it's not practical;
2) use ascii(), but it adds extra "" around the output and escape
backslashes and apostrophes (and it won't be possible to use _[0] in the
next line).
Also note that in Py3
>>> ['\ud800']
['\ud800']
>>> _[0]
'\ud800'
works, because U+D800 belongs to the category "Cs (Other, Surrogate)"
and it is escaped[2].
The best solution is probably to change the default error-handler of the
Python3 interactive interpreter to 'backslashreplace' in order to avoid
this behavior, but I don't know if it's possible only for ">>> foo" and
not for ">>> print(foo)" (print() should still raise an error as it does
in Py2).
This proposal has already been refused in the PEP3138[3] but there are
no links to the discussion that led to this decision.
I think this should be rediscussed and possibly changed, because, even
if can't see the "listOfJapaneseStrings"[4], I still prefer to see a
sequence of escaped chars than a UnicodeEncodeError.

New submission from Guillaume Desmottes <gdesmott at gnome.org>:
To reproduce:
- Launch a HTTP server listening on an Inet6 socket on, say, port 5555
- Try to connect using the IPv6 loopback:
http = httplib.HTTPConnection('[::1]:5555')
http.request('GET', '/foo')
r = http.getresponse()
print r.status
- You get 400 (bad-request) instead of 404
It seems that's because the HTTP request is wrong. Python sends this header:
Host: ::1:5555
but it should be:
Host: [::1]:5555
I'm using python 2.5.2-1ubuntu1 on Intrepid.

New submission from Erick Tryzelaar <idadesub at users.sourceforge.net>:
It would be really handy to add a way to portably kill process groups of
a process spawned with subprocess.Popen. My project starts a process,
which then starts other long running processes. Because of this process
tree, there's no way for me to portably kill all of those processes.
Would it be possible to extend subprocess with these features? I did
find someone who's already implemented this [1], and it's working well
in my project. There was some discussion about adding this, but it seems
no one actually committed a patch to implement it.
Anyway, I've attached a patch against python3.0's svn branch that
implements this. I don't have access to windows, so I'm not able to make
sure that the TerminateJobObject is correct, and works.

New submission from Jason R. Coombs <jaraco at jaraco.com>:
Using Python 2.5.4 and Python 2.6.1 on 32-bit python, when passing a
regular string to a function expecting pointer to a wide string
(wintypes.LPCWSTR), the function executes without problems.
When calling the same using Python 2.6.1 on 64-bit windows, the called
function appears not to recognize the parameter unless it is first
converted to unicode.
I discovered this when calling the WNetAddConnection2 function.
Assuming a properly-initialized NETRESOURCE, resource.
password = None
username = 'username at domain.com'
flags = 0
val = ctypes.windll.mpr.WNetAddConnection2W(
ctypes.byref(resource),
password,
username,
flags)
This method works fine on 32-bit python but fails on 64-bit python
unless username=unicode(username). The error returned is "The specified
password is incorrect", indicating that the username is in fact
incorrect because the correct username does not require a password.
I wish I had a better test case; I'll try to track down one that doesn't
require such a complex underlying API.
I'm not sure what the correct fix is for this, but regardless, I would
expect the behavior to be consistent for the same Python version
independent of word size.

For some reason the recently added test_ttk_guionly is causing Tcl to
abort on Mac. I would prefer to disable the test for now, except if some
mac owner has the time to fix it.
I would like to know the tcl version being used on the noller-osx86
buildslave too, if possible.
