New submission from Mark Summerfield <mark at qtrac.eu>:
>>> # Py30a3
>>> import locale
>>> locale.setlocale(locale.LC_ALL, "en_US.UTF8")
'en_US.UTF8'
>>> locale.format("%d", 12345, True)
'12,345'
>>> "{0:n}".format(12345)
'12345'
According to the docs the 'n' format should use the locale-dependent
separator, so I expected both strings to be '12,345'.
Also, it is a pity that locale.format() uses the old deprecated % syntax
rather than the much nicer and better str.format() syntax.

In-Reply-To: <1207052027.28.0.27225375953.issue2527@psf.upfronthosting.co.za>
Message-ID: <1207052027.28.0.27225375953.issue2527@psf.upfronthosting.co.za>
New submission from Peter Otten <__peter__ at web.de>:
I'd like to suggest a different approach than the one taken in rev.
54348 to improve timeit's scripting interface: allow passing it a
namespace. Reasons:
- It has smaller overhead for functions that take an argument:
>>> def f(a): pass
...
# trunk
>>> min(ht.Timer(lambda f=f: f(42)).repeat())
0.54068493843078613
# my patch
>>> min(mt.Timer("f(42)", ns=dict(f=f)).repeat())
0.29009604454040527
- it is more flexible. Example:
# working code, requires matplotlib
from timeit import Timer
from time import sleep
def linear(i):
sleep(.05*i)
def quadratic(i):
sleep(.01*i**2)
x = range(10)
y = []
for a in x:
y.append([min(Timer("f(a)", ns=dict(f=f, a=a)).repeat(1, 1))
for f in linear, quadratic])
from pylab import plot, show
plot(x, y)
show()
The above code works unaltered inside a function, unlike the hacks
using "from __main__ import ...".
- the implementation is simpler and should be easy to maintain.
The provided patch is against 2.5.1. If it has a chance of being
accepted I'm willing to jump through the necessary hoops:
documentation, tests, etc.

New submission from Tim Golden <mail at timgolden.me.uk>:
At present, os.access under Windows simply calls GetFileAttributes to
determine the readonly attribute (ignoring directories). The patch
attached combines this with the use of the AccessCheck API to compare
the user's permissions with those required for the path.
I'm assuming that ATTRIB and CACLS will be available for use in the unit
tests included.
I haven't altered the structure of the posix_access function at all
although I suspect that it could now be simplified now that we're not
supporting Win9x.

Message-ID: <1207077549.89.0.118557412226.issue2529@psf.upfronthosting.co.za>
New submission from Nick Guenther <kousu at users.sourceforge.net>:
I think I've found a bug in python's list comprehension parser. Observe:
>>> [e for i in j in ['a','b','c']]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'j' is not defined
Now, according to the grammar at http://docs.python.org/ref/lists.html,
a list comprehension is (condensed for clarity):
list_comprehension ::= expression list_for
list_for ::= "for" target_list "in" old_expression_list [list_for]
So a list comprehension should always be
[.... for ... in .... for ... in ... for ... in ...]
(that is, alternating 'for's and 'in's) but here I have a test case that
python happily tries to run that looks like
[... for ... in ... in ....]

New submission from Thomas Dimson <tdimson at gmail.com>:
Having a peculiar issue (exception raised despite being valid) when
defining a decorator that takes a class method as a callback. Here is a
cooked example:
def decorator( callback ):
def inner(func):
def application( *args, **kwargs ):
callback(*args,**kwargs)
func(*args,**kwargs)
return application
return inner
class DecorateMe:
@decorator( callback=DecorateMe.callback )
def youBet( self ):
pass
def callback( self ):
print "Hello!"
>>> DecorateMe().youBet()
Traceback (most recent call last):
File "<pyshell#0>", line 1, in <module>
DecorateMe().youBet()
File "C:\Python25\badpython.py", line 4, in application
callback(*args,**kwargs)
TypeError: unbound method callback() must be called with DecorateMe
instance as first argument (got DecorateMe instance instead)
If you change the line "callback=DecorateMe.callback" to
"callback=lambda x: DecorateMe.callback(x)" python gives you:
>>> DecorateMe().youBet()
Hello!
Mysteriously, I did encounter this during my coding with a non-cooked
decorator.

New submission from Daniel Diniz <ajaksu2 at users.sourceforge.net>:
Currently, Modules/itertoolsmodule.c lines 2471-2475 are:
PyDoc_STRVAR(permutations_doc,
"permutations(iterables[, r]) --> permutations object\n\
\n\
Return successive r-length permutations of elements in the iterable.\n\n\
permutations(range(4), 3) --> (0,1,2), (0,1,3), (0,2,3), (1,2,3)");
but that describes behavior of itertools.combinations. The correct
example is in a comment on line 2254 of the same file:
'permutations(range(3), 2) --> (0,1) (0,2) (1,0) (1,2) (2,0) (2,1)'
I used "misleading" instead of "wrong" because the current docstring
does show a subset of the real output and could be said to be
incomplete. If that is the case, I suggest being explicit:
'permutations(range(4), 3) --> (0, 1, 2), (0, 1, 3), (0, 2, 1), (0, 2,
3), (0, 3, 1), (0, 3, 2), (1, 0, 2), (1, 0, 3), (1, 2, 0), (1, 2, 3),

Subject: [New-bugs-announce] [issue2539] Windows Registry issue with 2.5.2
AMD64 msi
In-Reply-To: <1207188986.33.0.533862298048.issue2539@psf.upfronthosting.co.za>
Message-ID: <1207188986.33.0.533862298048.issue2539@psf.upfronthosting.co.za>
New submission from Jason <iggyboo at bestmail.us>:
I have tried multiple times and even checking manually, but the
Python 2.5.2 AMD64 msi installer does not register Python correctly, or
it doesn't enter it into the registry correctly. I'm not sure. I
install it after uninstalling 2.5.1 and and when I try to install
wxPython2.8 and pygtk-2.10.6 both give me an error that they cannot find
Python or its path in the registry. I reinstall 2.5.1 and it all works
perfectly. I'm using all default selections and just clicking
"Next,Next,Next, etc."

I noticed compiler warned "'longval' is not used anywhere."
And I found 'longval' was not initialized where HAVE_LONG_LONG
was not defined. Is attached patch intended behavior? Thanks.

According to

raw strings with \u and \U escape sequences should have these sequences
parsed as usual. However, they are currently escaped.

'\\u0020'

PyErr_ExceptionMatches must not fail, according to the docs. So an
error code from PyObject_IsSubclass() cannot be returned.
The attached patch calls PyErr_WriteUnraisable in this case, and returns
an arbitrary value (0 was chosen in the patch).

Sphinx seems to need tabs expanded in reST, but the autodoc extension
doesn't do so. The following patch is very small, and fixes the issue on
my system.
Oddly, I can reproduce this on a Linux system with doctools and docutils
trunk, but not on a Mac with doctools and docutils trunk vOv.

Subject: [New-bugs-announce] [issue2550] SO_REUSEADDR doesn't have the same
semantics on Windows as on Unix
In-Reply-To: <1207324680.68.0.575928167509.issue2550@psf.upfronthosting.co.za>
Message-ID: <1207324680.68.0.575928167509.issue2550@psf.upfronthosting.co.za>
New submission from Trent Nelson <tnelson at onresolve.com>:
Background: I came across this issue when trying to track down why
test_asynchat would periodically wedge python processes on the Windows
buildbots, to the point that they wouldn't even respond to SIGKILL (or
ctrl-c on the console).
What I found after a bit of digging is that Windows doesn't raise
EADDRINUSE socket.errors when you bind() two sockets to identical
host/ports *IFF* SO_REUSEADDR has been set as a socket option.
Decided to brighten up my tube journey into work this morning by
reading the Gospel's take on the situation. As per the 'SO_REUSEADDR
and SO_REUSEPORT Socket Options' section in chapter 7.5 of Stevens'
UNIX Network Programming Volume 1 (2nd Ed):
"With TCP, we are never able to start multiple servers that bind
the same IP address and same port: a completely duplicate binding.
That is, we cannot start one server that binds 198.69.10.2 port 80
and start another that also binds 198.69.10.2 port 80, even if we
set the SO_REUSEADDR socket option for the second server."
So, it seems at least Windows isn't adhering to this, at least on XP
and Server 2008 with 2.5-2.6. I've patched test_socket.py to
explicitly test for this situation -- as expected, it passes on Unix
(tested on FreeBSD in particular), and fails on Windows. I'd like to
commit this to trunk to see if any of the buildbots for different
platforms match the behaviour of Windows.

New submission from Benjamin Peterson <musiccomposition at gmail.com>:
According to the 2.6 docs, says you can set it yourself to control
bytecode generation. That doesn't work because the dont_write_bytecode
flag is set from command option and never looked at again. Either we
should remove this misleading information or use PySys_GetObject in
pythonrun.c where the flag is used.

New submission from Guido van Rossum <guido at python.org>:
In 2.x, \uDDDD and \UDDDDDDDD are interpreted as Unicode escapes in
raw Unicode strings. That was a mistake, but we can't fix it (except
when using "from __future__ import unicode_literals"). In 3.0, \u or
\U in a raw string should have no special meaning -- it's just a
backslash followed by 'u' or 'U'.
This was fixed in 3.0a3. It seems to have reverted to the old (2.x)
behavior in 3.0a4.
THIS MUST BE FIXED!

result. Here's the make output after simply removing all '*ctypes*'

Message-ID: <1207475239.5.0.0696358951433.issue2562@psf.upfronthosting.co.za>
New submission from Tarek Ziad? <ziade.tarek at gmail.com>:
If I try to put my name in the Author field as a string field,
it will brake because distutils makes the assumption that
the fields are string encoded in ascii, before it decodes
it into unicode, then encode it in utf8 to send the data.
See in distutils.command.register.post_to_server :
value = unicode(value).encode("utf-8")
One way to avoid this error is to provide unicode for all field,
but will fail farther if setuptools is used, because
this other package makes the assumption that the fields *are* strings::
self.run_command('egg_info')
...
distutils/dist.py", line 1047, in write_pkg_info
pkg_info.write('Author: %s\n' % self.get_contact() )
UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' in
position 18: ordinal not in range(128)
So I guess distutils shouldn't guess that it receives ascii strings
and do a raw unicode() call, and should make the assumption that
it receives unicode fields only.
Since many packages out there use strings, I have left a unicode()
call in my patch, together with a warning.
test provided.

New submission from Mark Hammond <mhammond at users.sourceforge.net>:
The move to vs2008 has caused .manifest files to be created next to
distutils created extensions modules, rather than being embedded as
recommended by Microsoft.
See http://msdn2.microsoft.com/en-us/library/ms235591(VS.80).aspx
The attached patch achieves this by telling the compiler to generate the
manifest in the temp dir, them embeds that manifest using mt.exe
Adding Christian for comment (hopefully the correct Christian this time
- sorry about that :)

"%S Second as a decimal number [00,61]. (2)
(2) The range really is 0 to 61; this accounts for leap seconds and the
(very rare) double leap seconds."
That is wrong. There NEVER can be two leap seconds in one moment, since UTC
time keep the difference between UTC and UT1 from exceeding ?0.9 s.
Leap seconds occur only at the end of a UTC month, and have only ever been
inserted at the end of June 30 or December 31.
So, 61 is wrong, real seconds range from 0 to 60 inclusive.

New submission from pk <pk at q-leap.com>:
Hello,
the urlparse() function accepts a parameter default_scheme, to be used
if the address given does not contain one, but I cannot make
use of it, because I would expect these two returning
identical values:
>>> from urlparse import urlparse
>>> urlparse("www","http")
('http', '', 'www', '', '', '')
>>> urlparse("http://www","http")
('http', 'www', '', '', '', '')
This has been reported about six years ago but apparently
the behaviour hasn't changed. I cannot imagine that this
really is the intended behaviour.
Regards,
pk

In 3.0, r'\u1234' is a string of 6 characters (\, u, 1, 2, 3, 4). In
2.6, after "from __future__ import unicode_literals" it is a string of
one character (code point 0x1234). IMO the 3.0 behavior should be
imported from the future as well (using the same import).

There is currently no way in the configure script to specify an
alternate name for Python.framework. If I want to completely separate
versions of Python (e.g. for 3.0 alphas and/or Stackless), I have to
manually edit configure.in and configure to change the framework name.
It would be much more convenient if --with-framework could take an
optional parameter of the framework name to use.

New submission from bms <bms at incunabulum.net>:
Hi,
Here is a patch to add RFC 3768 SSM Multicast support to low-level
Python socket module as of 2.5.1.
I have not tested the setsourcefilter()/getsourcefilter() socket member
functions other than compiling the patch on a Gentoo Linux 2008.0 box
w/2.6 Linux kernel.
These APIs should be fairly portable. Note that I haven't added any
other configure glue, like the rest of socket, support is very low level
and getting the arguments to struct.pack() right is the user's problem.
cheers
BMS

lack of socket buffer

Message-ID: <1207601711.27.0.24453345668.issue2576@psf.upfronthosting.co.za>
New submission from Aren Olson <reacocard at gmail.com>:
This is a reposting of issue 508157, as requested by gvanrossum.
The socket file object in httplib is opened without any buffering
resulting in very slow performance of read(). The specific problem is
in the httplib.HTTPResponse constructor. It calls sock.makefile() with
a 0 for the buffer size. changing the buffer size to 4096 improved the
time needed to download 10MB from 15.5s to 1.78s, almost 9x faster.
Repeat downloads of the same file (meaning the server now has the file
cached in memory), yield times of 15.5s and 0.03s, a 500x improvement.
When fetching from a server on the local network, rather than from
localhost, these times become 15.5s and 0.9s in both cases, a 17x
speedup. Real-world situations will likely be a mix of these, however it
is safe to say the speed improvement will be substantial. Adding an
option to adjust the buffer size would be very welcome, though the
default value should still be zero, to avoid the issues already
mentioned in issue 508157.
These speed results were obtained with python2.5 and apache2 under
Ubuntu linux, using the code found here: http://pastebin.ca/973578

The 'toctree references unknown document' can be misleading when the
document name includes whitespace.
For example, I had mistakenly created an index file of the form
.. toctree::
:maxdepth: 2
overview
(note that overview has a leading space). In the error message is was
very difficult to see that this was a problem, as the error message was
WARNING: /home/henry/code/bdec.docs/doc/source/index.rst:8: (WARNING/2)
toctree references unknown document overview
By putting the document name in quotes, it becomes clearer what the
problem was.
WARNING: /home/henry/code/bdec.docs/doc/source/index.rst:8: (WARNING/2)
toctree references unknown document ' overview'
A patch to include these quotes has been attached.

manual entry

Message-ID: <1207621575.04.0.143306946794.issue2580@psf.upfronthosting.co.za>
New submission from Terry J. Reedy <tjreedy at udel.edu>:
Based on c.l.p discussion with Mark Dickinson, who supplied details and
corrections, we propose the following for the int() entry at
http://docs.python.org/dev/3.0/library/functions.html#int
int([number | string[, radix]])
Convert a number or string to an integer. If no arguments are given,
return 0. If a number is given, return number.__int__(). Conversion of
floating point numbers to integers truncates towards zero. A string
must be a base-radix integer literal optionally preceded by '+' or '-'
(with no space in between) and optionally surrounded by whitespace. A
base-n literal consists of the digits 0 to n-1, with 'a' to 'z' (or 'A'
to 'Z')having values 10 to 35. The default radix is 10. The allowed
values are 0 and 2-36. Base-2, -8, and -16 literals can be optionally
prefixed with 0b/0B, 0o/0O, or 0x/0X, as with integer literals in code.
Radix 0 means to interpret exactly as a code literal, so that the
actual radix is 2, 8, 10, or 16, and so that int('010',0) is not legal,
while int('010') is.
The revised signature makes it clear from the start that *radix* can
only follow *string*, so no sentence to that effect is needed in the
text. The other changes are to discuss the signature in order and to
add details. We believe the above accurately reflects the
intended/actual behavior once the no-space-after-sign patch is applied.
(I don't know if that made it into .0a4).
Some of this might apply to the 2.6 docs, except that the no-space patch
will apparently not be backported. I believe the acceptable strings are
a bit different also, at least for octals, but I am not sure.

New submission from Mark Hammond <mhammond at users.sourceforge.net>:
The attached patch adds basic UAC support to bdist_wininst created
installers. A new option '--user-access-control' has been added to
bdist_wininst, which is written to the INI file read by the installer.
The installer reads this value: if it is 'force', elevation is always
requested, if it is 'auto', elevation is requested when Python is
installed in HKLM. 'none' (the default) means nothing UAC related
happens at all.
The elevation happens by having the installer re-execute itself using
ShellExecute.
I've also ensured the code builds for all versions of VS we support. As
a result, it was necessary to change the old bdist_wininst project files
to point to the later zlib version Python itself uses. All these
changes are in the patch.

Hi,
This is my first problem with anything Python :-) and my first issue.
Doing in the following:
urlparse.urljoin( 'http://site.com/', '../../../../path/' )
'http://site.com/../../../../path/'
urlparse.urljoin( 'http://site.com/', '/path/../path/.././path/./' )
'http://site.com/path/../path/.././path/./'
These URLs are normalized to http://site.com/path/ in both Firefox and
Google (the google spider would follow these OK)
I think the documentation could be improved to point at the
posixpath.py normpath function and how it solves the above. I blogged a
how to:
http://teethgrinder.co.uk/blog/Normalize-URL-path-python/
I hope my bug report is OK. Thanks for all the code :-)

According to the documentation there is not suppose to be numeric
overflow in python 2.5. However....
If you run a for loop with the range(1, 300000000)a couple of times (for
me 2 or 3 times worked) in the IDLE (1.2.2)GUI . It will cause what
appears to be a memory leak, at least under vista home edition. Haven't
tested out other platforms yet. Vista's logon process will fail to start
security dialog as well if you try to ctrl-alt-del. Which effectively
cripples the system. I haven't tested to see if the condition will get
better over long period of time. I've waited a max of 10 minutes for the
system to respond.
I tested running the script multiple times under cmd in windows, and it
spits out a memory error after a minute of not responding and then the
cmd prompts will close and the system will begin responding. So it
appears to be isolated to IDLE.

either of the code paths in PyObject_MALLOC()-- both of which will
incorrectly allocate memory.
This may not seem like a big deal, but I'm posting this instead of
filing a bug for every place this screws you guys over.

The PyOS_vsnprintf() contains the caveat that the length parameter
cannot be zero, however this is only enforced via assert() which is
compiled out. As a result if the length parameter is zero then the
function will underflow and write a null byte to invalid memory.

New submission from Justin Ferguson <justin.ferguson at ioactive.com>:
On architectures that do not have a vsnprintf() in their standard
library Python attempts to emulate it. When doing so, the implementation
ambitiously allocates more memory than requested without verifying the
sanity of the summed value. As a result it becomes possible (although
unlikely) for an integer overflow to occur misallocating memory and
causing a buffer overflow.

New submission from Justin Ferguson <justin.ferguson at ioactive.com>:
The S_unpack_from() function in Modules/_struct.c does not adequately
validate its arguments, potentially causing an out-of-bounds read
access. It should be noted that the check at line 1561 is inadequate for
obscene values of offset. Finally, because they're not really important
and I really don't want to type them all up-- you guys might want to go
through your code-- especially the modules and look for constructs where
an empty string will cause memory to be uninitialized-- look at the
audioop module for examples of what I mean-- the only thing that
actually saved you guys from overflows there was that the loops you
write with use the same variable.

New submission from Justin Ferguson <justin.ferguson at ioactive.com>:
The imgfile module contains multiple integer overflows, this module is
only used on SGI boxes and is likely mostly unused and thus is fairly
low priority imho-- no repros, no poc, no sgi box :/
I'm only going to post one to give you the idea, there's no need for me
to (further) spam the bug database by filing a bug for each one of
these, they're all pretty much the same.
Here the variables xsize, ysize and zsize are all externally derived.
While xsize and zsize are sanity checked, ysize is not. This potentially
results in an integer overflow/misallocation at line 133 and writes to
invalid memory in the calls to getrow()

102 return NULL;

116 xsize = image->xsize;
117 ysize = image->ysize;
118 zsize = image->zsize;
119 if ( zsize != 1 && zsize != 3) {
120 iclose(image);
121 PyErr_SetString(ImgfileError,
122 "Can only handle 1 or 3 byte pixels");
123 return NULL;
124 }
125 if ( xsize > 8192 ) {
126 iclose(image);

128 "Can't handle image with > 8192
columns");

2to3 should be able to translate the code snippet below successfully.
First guess: generalizing fix_dict's notion of special contexts would do
the trick.

chosen = []
while len(chosen) < 6:
number = random.choice(numbers)
numbers.remove(number)
chosen.append(number)
chosen.sort()

to default to next positional argument (e.g., "{}")

New submission from Bruce Frederiksen <dangyogi at gmail.com>:
Being forced to number the arguments when using positional arguments in
a format string is difficult to maintain. Adding an argument to the
format string either requires renumbering all subsequent arguments, or
using an out of sequence number such that the order of the format()
arguments no longer matches the order of the "{...}" arguments. Making
the integer optional would solve this. Thus, "{}" would be like the old
"%s" where it was far easier to add %s arguments in the middle of the
format string.

New submission from Pau Aliagas <linuxnow at newtral.org>:
I wanted to use urllib2 with something as usual as binding to a given
network interface and it was incredibly complex. I also did not like the
usual propodes solution to timeout the connections: set the global
socket timeour. I needed a different timeout for each connection.
So I took my time, I learnt about httplib and urllib2 and made a patch
to enhance both libraries.
BindingHTTPConnectionWithTimeout extends HTTPConection with supports
timeouts and a binding address.
BindingHTTPHandlerWithTimeout extends HTTPHandler and basically uses the
new http class provided.
The patch is really simple and would make a great addition to the
standard library. I've tried to follow the style amd copied similar
methods, giving the due credits.
I hope you find it useful and consider it for inclusion.

New submission from Matthias Klose <doko at debian.org>:
r61009 on the 2.5 branch
- Bug #1389051, 1092502: fix excessively large memory allocations when
calling .read() on a socket object wrapped with makefile().
causes a regression compared to 2.4.5 and 2.5.2:
When reading from urllib2 file descriptor, python will read the data a
byte at a time regardless of how much you ask for. python versions up to
2.5.2 will read the data in 8K chunks.
This has enough of a performance impact that it increases download time
for a large file over a gigabit LAN from 10 seconds to 34 minutes. (!)
Trivial/obvious example code:
f =
urllib2.urlopen("http://launchpadlibrarian.net/13214672/nexuiz-data_2.4.orig.tar.gz")
while 1:
chunk = f.read()
... and then strace it to see the recv()'s chugging along, one byte at a
time.

Message-ID: <1207822509.14.0.860100540347.issue2605@psf.upfronthosting.co.za>
New submission from Piet Delport <pjdelport at gmail.com>:
Short version: __get__/__set__/__delete__ attributes on descriptor objects
(as opposed to their types) are treated inconsistently as part of the
descriptor
protocol: the documentation and support code includes them; the core
implementation doesn't.
Example:
class D(object):
__get__ = lambda self, i, o: 'D'
class C(object):
d = D()
d.__get__ = lambda i, o: 'd'
d.__set__ = lambda i, v: 1/0
c = C()
According to pydoc and inspect, and the description in the reference manual
(section 3.4.2.3), d's __get__ and __set__ override D's:
>>> inspect.isdatadescriptor(C.__dict__['d'])
True
>>> help(C)
class C(__builtin__.object)
| Data descriptors defined here:
...
| d
>>> type(c).__dict__['d'].__get__(c, type(c))
'd'
>>> type(c).__dict__['d'].__set__(c, 5)
ZeroDivisionError: integer division or modulo by zero
According to CPython, they have no effect:
>>> c.d
'D'
>>> c.d = 5; c.d
5
PEP 252 notes: "For speed, the get and set methods are type slots", which
points to the CPython behavior being an intentional concession for
performance.
Should CPython respect descriptor object attributes, if reasonable
performance
can be maintained? Otherwise, should the documentation and support code be
changed to ignore them?

In Py30a4's trace.py there is this:

calls.sort()
which causes:
AttributeError: 'dict_keys' object has no attribute 'sort'
There are two other occurrences of this idiom in trace.py (just search
for ".sort"). I guess they should be easy to fix.

New submission from Andreas Eisele <eisele at dfki.de>:
I need to count pairs of strings, and I use
a defaultdict in a construct like
count[a,b] += 1
I am able to count 50K items per second on a very fast machine,
which is way too slow for my application.
If I count complete strings like
count[ab] += 1
it can count 500K items/second, which is more reasonable.
I don't see why there is a performance penalty of a factor
of 10 for such a simple construct.
Do I have to switch to Perl or C to get this done???
Thanks a lot for any insight on this.
Best regards,
Andreas
PS.: The problem seems to exist for ordinary
dicts as well, it is not related to the fact that
I use a defaultdict
PPS: I also tried nested defaultdicts
count[a][b] += 1
and get the same slow speed (and 50% more memory consumption)

If @test file is not writable in the current directory,

if TESTFN is an absolute path:
$ mkdir @test
$ make test
..
4 tests failed:
test_import test_site test_urllib test_zipfile

For example,
$ ./python -E -tt ./Lib/test/regrtest.py -l test_urllib
test_urllib
test test_urllib failed -- Traceback (most recent call last):
File "Lib/test/test_urllib.py", line 84, in test_geturl

AssertionError: 'file:///tmp/@test' != '/tmp/@test'
Note that I discovered this problem after (probably killed) test_os left
@test/ directory behind. It took me a while to realize what happened.
I think the simplest fix is to os.chdir to '/tmp' if @test is not
writable instead of changing TESTFN. Other solutions may include
deleting or renaming @test with a warning when it exists, using
tempnam() instead of @test and bailing out if cwd is not writeable etc.

New submission from Brad Miller <bonelake at gmail.com>:
I use Python in my CS1 and CS2 curriculum and I have a question.
As I've been using the Python 3.0 alphas one of the things that I am
bothered by is that I cannot see the sequence produced by range
without introducing students to the list() function.
I typically introduce range on day 1 of class and show students what
it produces without making a big deal out of the fact that it creates
a list. They all accept this and things work out nicely when I
introduce lists for real in a week or two.
My question is why couldn't the __str__ method for the range object be
more friendly and show a representation of the sequence? I understand
why __repr__ should return range(0,10) for an object created using
range(10) but couldn't print(range(10)) produce [0, 1, 2, ... 9]
The ... could even be used if the sequence were excessively long.
I have attached a patch, which follows the suggestion from Guido on how
to format the string so it is not confused with a list.
This is my first attempt at patching any part of the C code for Python.
Please let me know what should be changed and If I've missed something.
In particular I wonder whether I should be nesting any calls to PyNumber
functions or whether temporary variables should be used to avoid leaking
memory?
In addition I get the following warning on the line where I install the
range_str function in the PyRange_Type array.
Objects/rangeobject.c:357: warning: initialization from incompatible
pointer type

It'd be nice if there was a facility to force a particular test to be
re-run in verbose mode with the most recent build via the buildbot web
interface. It would allow us to get a bit more information about
what's going on when the buildbots report stuff like this:
test_property
test_cprofile
test_signal
command timed out: 1800 seconds without output, killing pid 214235
SIGKILL failed to kill process
using fake rc=-1
program finished with exit code -1
Neal or Martin, if neither of you have the desire/bandwidth to look
into this, I'm more than happy to take it on. Suspect it'd involve a
buildbot change on dinsdale right?

Subject: [New-bugs-announce] [issue2614] Console UnicodeDecodeError s once
more
In-Reply-To: <1207903659.28.0.871159161104.issue2614@psf.upfronthosting.co.za>
Message-ID: <1207903659.28.0.871159161104.issue2614@psf.upfronthosting.co.za>
New submission from anatoly techtonik <techtonik at gmail.com>:
Python debugging under console is a PITA, because it has a bad habit to
fail with UnicodeEncodeError in case of unknown encoding in output. It
quickly turns into a headache when inspecting methods like in the
following example running under windows:
>>> import active_directory
>>> users = active_directory.search ("objectCategory='Person'",
"objectClass='User'")
>>> u = users.next()
>>> u = users.next()
>>> u = users.next()
>>> u.dump()
LDAP://CN=L????????,CN=Users,DC=dom,DC=com
{
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "build\bdist.win32\egg\active_directory.py", line 495, in dump
File "C:\Python25\lib\codecs.py", line 303, in write
data, consumed = self.encode(object, self.errors)
File "C:\Python25\lib\encodings\cp1251.py", line 12, in en
code
return codecs.charmap_encode(input,errors,encoding_table)
UnicodeDecodeError: 'ascii' codec can't decode byte 0x84 in position 8:
ordinal
not in range(128)
Will this be fixed in Py3k to allow range(255) in case of unknown
encoding? Or will there be a new wrapper function - some
rawhexprint(...) that will temporary change sys.output encoding for the
time arguments are executed and process out of range symbols in output
stream according to its embedded rules (i.e. converting to hex
representaton). Another function can be supplied to write raw bytes to
console as-is. Raw write is preferable as it gives the possibility to
redirect output to a file and inspect it later.
These encoding issues in my POV is the stumbling block that makes
scripting in Python 2.x harder for non-english users and hampers overall
Python adoption. Is this going change in Py3k?

xml.dom.minidom details three methods: writexml(), toxml(),

In the documentation for writexml() the encoding argument is explained,
but toprettyxml() refers to toxml() for the details, which are not
present there.

New submission from Kevin Walzer <wordtech at users.sourceforge.net>:
The Tile module adds support for the platform-native themed widgets now
available in Tk 8.5's core (ttk:: namespace in Tk terms). The module
also supports the ttk:: namespace for Tk 8.4 if a separate Tk extension
is installed. Adding this module to the core lib-tk library will make it
simple for Tkinter developers to access the improved, modern widget set
now available.
The module was originally developed by Martin Franklin. I have updated
and maintained it for the past two years. Martin Franklin has granted me
permission to submit it for inclusion in the lib-tk core; documentation
available on request.

Message-ID: <1207953338.18.0.167765254153.issue2620@psf.upfronthosting.co.za>
New submission from Justin Ferguson <justin.ferguson at ioactive.com>:
174 static
175 int unicode_resize(register PyUnicodeObject *unicode,
176 Py_ssize_t length)
177 {
[...]
201
202 oldstr = unicode->str;
203 PyMem_RESIZE(unicode->str, Py_UNICODE, length + 1);
[...]
209 unicode->str[length] = 0;
210 unicode->length = length;
211
95 #define PyMem_RESIZE(p, type, n) \
96 ( assert((n) <= PY_SIZE_MAX / sizeof(type)) , \
97 ( (p) = (type *) PyMem_REALLOC((p), (n) * sizeof(type)) ) )
The unicode_resize() function acts essentially as a wrapper to
realloc(), it accomplishes this via the PyMem_RESIZE() macro which
factors the size with the size of the type, in this case it multiplies
by two as Py_UNICODE is typedef'd to a wchar_t. When resizing large
strings, this results in an incorrect allocation that in turn leads to
buffer overflow.
This is specific to the Unicode objects, however I would not be
surprised to see that other types have this complication as well. Please
see attached proof of concepts.

New submission from Kjell Braden <fnord at pentabarf.de>:
Distutils should tell swig to create it's C wrapper file into the
temporary directory (eg. build/temp.linux-i686-2.5) and to write the
language specific files to the library directory (eg.
build/lib.linux-i686-2.5).
Rationale:
Without the language specific files, python swig extensions won't be
able to run, so they should definetly be distributed by distutils.
The wrapper files are build by-products and should therefore be in the
temporary directory, so they get cleaned up on "setup.py clean".

First time I noticed it during compilation of python3 r62301, then

Step "./python -E ./setup.py -q build" called by make never ends (and
there is no output). Just "/python" behaves the same: it eats memory
and prints nothing. Gcc 3.4.6 works fine. Previous versions of gcc 4
were working too, but I didn`t tested them now.
My system: gcc 4.3.0, kernel 2.6.24.zen5.20080410 (with zen patchset,
can test again with vanilla 2.6.24, or if you say it is too old I will
compile 2.6.24.4), glibc 2.7, Arch GNU/Linux.

New submission from Jonathan <jbell at scrippsweb.com>:
About a year ago I found myself fighting a broken FTP server that
couldn't handle multiple passive data transfers through a firewall or
NATed connection. Thankfully, this same problem server supports block
transmission mode, which allows a client to create a single data
connection for transferring multiple files.
I've attached a patch (and sample debug output) for the latest trunk.
Might this be useful to anyone else in any way? I realize any MODE
option rather than S is widely unsupported and possibly an edge case,
but getting this into trunk would be preferable. We've been running this
code under Python2.3 for nearly a year -- the jobs run several times per
hour -- and are extremely happy with the results.

New submission from Gregory P. Smith <greg at krypto.org>:
In _PyUnicode_New() a unicode object is taken from the freelist but if
the unicode_resize() call fails and returns -1, the goto onerror calls
_Py_ForgetReference on the unicode object... But it has NULL _ob_prev
and _ob_next values causing a crash when they're used.
How to reproduce:
* Make a 32-bit --with-pydebug build of Python trunk.
* Run it on a machine with lots of ram (at least 3gigs recommended, or
lots of swap and a heap of patience):
./python
Python 2.6a2+ (trunk:62336M, Apr 13 2008, 18:51:30)
>>> msg = 'A'*2000111222
>>> x = msg.decode('utf8')
It segmentation faults in _Py_ForgetReference.

Subject: [New-bugs-announce] [issue2630] repr() should not escape non-ASCII
characters

New submission from atsuo ishimoto <ishimoto at users.sourceforge.net>:
In py3k, repr() escapes non-ASCII characters in Unicode to \uXXXX as
Python 2. This is unpleasant feature if you are working with non-latin
characters. This issue was once discussed by Hye-Shik Chang[1], but was
rejected. Here's a new challenge for Python 3 to fix issue.
In this patch, repr() converts special ascii characters such as "\t",
"\r", "\n", but doesn't convert non-ASCII characters to \uXXXX form.
Non-ASCII characters are converted by TextIOWrapper on printing. I set
'errors' attribute of sys.stdout and sys.stderr to 'backslashreplace', so
un-printable characters are converted to '\uXXXX' if your console
cannot print such characters.
This patch breaks five regr tests on my environment.
I'll fix these tests if this patch is acceptable.

the instruction requires two parameters to be on the stack.
TOS and TOS1 should map to the fromlist and level parameters to the

http://docs.python.org/lib/node528.html (17.1.1 Using the subprocess

If env is not None, it defines the environment variables for the new
process.
This is too vague to be useful. If it's not None, what should it be? A
dictionary in the style of os.environ? A sequence of name/value pairs? A
string with some sort of delimiter between each entry?

Note: this is (sort of) related to Issue2633.
http://docs.python.org/lib/os-process.html (14.1.5 Process Management).
The docs for os.execvpe() say, "the env parameter must be a mapping which
is used to define the environment variables for the new process". It's
not clear if this mapping replaces the existing environment, or defines
additional entries which are added to the existing environment. This
should be clarified.
This applies to the spawn*() methods too.

Subject: [New-bugs-announce] [issue2636] Regexp 2.6 (modifications to
current re 2.2.2)
In-Reply-To: <1208260672.14.0.711874677361.issue2636@psf.upfronthosting.co.za>
Message-ID: <1208260672.14.0.711874677361.issue2636@psf.upfronthosting.co.za>
New submission from Jeffrey C. Jacobs <timehorse at users.sourceforge.net>:
I am working on adding features to the current Regexp implementation,
which is now set to 2.2.2. These features are to bring the Regexp code
closer in line with Perl 5.10 as well as add a few python-specific
niceties and potential speed-ups and clean-ups.
I will be posting regular patch updates to this thread when major
milestones have been reach with a description of the feature(s) added.
Currently, the list of proposed changes are (in no particular order):
1) Fix <a href="http://bugs.python.org/issue433030">issue 433030</a> by
adding support for Atomic Grouping and Possessive Qualifiers
2) Make named matches direct attributes of the match object; i.e.
instead of m.group('foo'), one will be able to write simply m.foo.
3) (maybe) make Match objects subscriptable, such that m[n] is
equivalent to m.group(n) and allow slicing.
4) Implement Perl-style back-references including relative back-references.
5) Add a well-formed, python-specific comment modifier, e.g. (?P#...);
the difference between (?P#...) and Perl/Python's (?#...) is that the
former will allow nested parentheses as well as parenthetical escaping,
so that patterns of the form '(?P# Evaluate (the following) expression,
3\) using some other technique)'. The (?P#...) will interpret this
entire expression as a comment, where as with (?#...) only, everything
following ' expression...' would be considered part of the match.
(?P#...) will necessarily be slower than (?#...) and so only should be
used if richer commenting style is required but the verbose mode is not
desired.
6) Add official support for fast, non-repeating capture groups with the
Template option. Template is unofficially supported and disables all
repeat operators (*, + and ?). This would mainly consist of documenting
its behavior.
7) Modify the re compiled expression cache to better handle the
thrashing condition. Currently, when regular expressions are compiled,
the result is cached so that if the same expression is compiled again,
it is retrieved from the cache and no extra work has to be done. This
cache supports up to 100 entries. Once the 100th entry is reached, the
cache is cleared and a new compile must occur. The danger, all be it
rare, is that one may compile the 100th expression only to find that one
recompiles it and has to do the same work all over again when it may
have been done 3 expressions ago. By modifying this logic slightly, it
is possible to establish an arbitrary counter that gives a time stamp to
each compiled entry and instead of clearing the entire cache when it
reaches capacity, only eliminate the oldest half of the cache, keeping
the half that is more recent. This should limit the possibility of
thrashing to cases where a very large number of Regular Expressions are
continually recompiled. In addition to this, I will update the limit to
256 entries, meaning that the 128 most recent are kept.
8) Emacs/Perl style character classes, e.g. [:alphanum:]. For instance,
:alphanum: would not include the '_' in the character class.
9) C-Engine speed-ups. I commenting and cleaning up the _sre.c Regexp
engine to make it flow more linearly, rather than with all the current
gotos and replace the switch-case statements with lookup tables, which
in tests have shown to be faster. This will also include adding many
more comments to the C code in order to make it easier for future
developers to follow. These changes are subject to testing and some
modifications may not be included in the final release if they are shown
to be slower than the existing code. Also, a number of Macros are being
eliminated where appropriate.
10) Export any (not already) shared value between the Python Code and
the C code, e.g. the default Maximum Repeat count (65536); this will
allow those constants to be changed in 1 central place.
11) Various other Perl 5.10 conformance modifications, TBD.
More items may come and suggestions are welcome.
-----
Currently, I have code which implements 5) and 7), have done some work
on 10) and am almost 9). When 9) is complete, I will work on 1), some
of which, such as parsing, is already done, then probably 8) and 4)
because they should not require too much work -- 4) is parser-only
AFAICT. Then, I will attempt 2) and 3), though those will require
changes at the C-Code level. Then I will investigate what additional
elements of 11) I can easily implement. Finally, I will write
documentation for all of these features, including 6).
In a few days, I will provide a patch with my interim results and will
update the patches with regular updates when Milestones are reached.

Message-ID: <1208272151.95.0.897886992301.issue2637@psf.upfronthosting.co.za>
New submission from Tim Lesher <tlesher at gmail.com>:
The urllib.quote docstring implies that it quotes only characters in RFC
2396's "reserved" set.
However, urllib.quote currently escapes all characters except those in
an "always_safe" list, which consists of alphanumerics and three
punctuation characters, "_.-".
This behavior is contrary to the RFC, which defines "unreserved"
characters as alphanumerics plus "mark" characters, or "-_.!~*'()".
The RFC also says:
Unreserved characters can be escaped without changing the semantics
of the URI, but this should not be done unless the URI is being used
in a context that does not allow the unescaped character to appear.
This seems to imply that "always_safe" should correspond to the RFC's
"unreserved" set of "alphanum" | "mark".

New submission from Ron Longo Work <longorh at npt.nuwc.navy.mil>:
When a Tkinter window comes up that uses tkSimpleDialog to construct a
dialog box, the window first flashes on the screen as an unpopulated
top-level window, before being drawn in its completed state.
This problem is easily corrected by adding two lines of code to the
constructor for class Dialog in tkSimpleDialog.py. The first line of
the constructor reads Toplevel.__init__( self, parent ). After this
line insert self.overrideredirect( True ). The second line from the
last in this constructor reads self.initial_focus.focus_set(), just
before this line insert self.overrideredirect( False). That's it.
I've attached the revised version of this file.

New submission from Roy Smith <roy at panix.com>:
The current doc says, "Copy the contents of the file named src to a file
named dst". Anybody used to the unix shell "cp" command would assume that
dst could be a directory, in which case the true destination is a file in
that directory with the same basename as src. Experimentation shows that
this is not true. A note something like the following would help:
Note: unlike the "cp" shell command, dst may not be a directory; it must
be a path to a file in that directory.
True, there's no place in the docs which actually says a directory is
valid for dst, but the name of the module is shutil, so it's reasonable
for people to assume that these act the same way as the corresponding unix
shell commands. It should be stated up front that this is not true, to
avoid confusion.

On my Mac, /usr/local/bin/python2.5 is a symlink to
"../../../Library/Frameworks/Python.framework/Versions/2.5/bin/python2.5".
When I install Mercurial from source, the "mercurial" package is
installed at "/usr/local/lib/python2.5/site-packages/mercurial", so the
installation is broken. Since "site-packages" appears nowhere in the
Mercurial source tree, I think it's setuptools (not Mercurial) that is
getting this wrong.
Mercurial's setup.py can be seen here:
(as of this writing)
http://hg.intevation.org/mercurial/crew/file/628da4a91628/setup.py
(the latest)
http://hg.intevation.org/mercurial/crew/file/tip/setup.py
I'm not sure what the Right Thing would be, but if it's agreed that the
current behavior is a hack, then `(p for p in sys.path if
p.endswith('site-packages')).next()`, falling back to the current
behavior, seems like a better hack.
Happy to patch, if someone can advise me; MvL?

New submission from Wesley Spikes <wesley.spikes at gmail.com>:
I've searched and did not find any open ticket to make suggestions on,
so I'm posting it here.
You currently have posted "The MSI installers for Python 3.0a4 are
compiled with the new Visual Studio 2008 Professional version.
Therefore Python depends on the -Visual C++ runtime library 9.0. We
currently don't package this library properly, which means that non-
Administrator installation is currently not supported. Contributions to
fix this problem are welcome."
Two potential fixes, both of which should be very readily doable. First
one is to set the Linking option in MSVC++ to a static link to the CRT.
This in-builds the library with Python. (Options /MT and /MTd, for
release and debug versions, respectively.)
The other potential resolution for Non-Admin installs, which may or may
not be more stable, is to include the MSVCRT DLLs into the directory
containing the Python installation. If needed, you may have to register
these files manually into the HKCU hive.
Hope that helps with your described packaging issue with the installer.
(Classified under Build and Installation, since it deals with both
halves -- feel free to reclassify as appropriate.)

New submission from Niall O'Higgins <niallo at unworkable.org>:
I do a lot of urllib2 reads of HTTP URLs. From time to time, I see the
following exception being thrown:
File "/usr/local/lib/python2.5/socket.py", line 291, in read
data = self._sock.recv(recv_size)
File "/usr/local/lib/python2.5/httplib.py", line 509, in read
return self._read_chunked(amt)
File "/usr/local/lib/python2.5/httplib.py", line 548, in _read_chunked
chunk_left = int(line, 16)
ValueError: invalid literal for int() with base 16: ''
The chunked reading code does not expect an empty string. I have
attached a patch which checks for ValueError in this case and sets
chunk_left to 0, which will break from the loop. I am not entirely sure
if this is the correct fix, however, but it should illustrate the problem.

I am using a web framework (TurboGears w/ genshi templating) which often
pass around dictionaries as keyword arguments in order to have 1 to 1
representation of json data and URL parameters. This is usually fine
except when using libraries such as simplejson which encodes all of the
keywords as unicode.
Attached is a patch which is most likely just the tip of the iceberg but
hopefully it turns out to be this easy.

The current version of the receipe moneyfmt doesn't have a leading "0"

The attached patch adds a new parameter "zero". The parameter is empty
per default and can set to "0" print a leading "0". The examples are

Possibly the new option should be "0" per default.

There are 2 changes from the original fnmatch.py file:
(1) The documentation for the fnmatch() function has been updated to
reflect the new functionality
(2) The translate() function has been completely replaced.
I ran test_fnmatch.py and test_glob.py and both ran without errors.

New submission from Rick Harris <rconradharris at gmail.com>:
Here is a bug in Python 2.5 which would be nice to fix for Py3k (since
we are already breaking compatibility):
Take a string:
s = "Hello"
Create a KeyError exception with that string:
e = KeyError(s)
Counterintuitively, casting the exception to a string doesn't return the
same string:
str(e) != s
Instead, when KeyError is cast to a string it affixes single-quotes
around the string.
I have create a test which shows that the other built-in exceptions
(except for 3 Unicode Errors which seem to be unusual in that they don't
accept just a string), do indeed round-trip the string unaltered.
This actually caused a bug (in an old version of zope.DocumentTemplate).
I am including the test case I wrote for now; I will begin looking into
a solution shortly and hopefully whip up a patch.

New submission from Thomas Heller <theller at ctypes.org>:
This patch implements a .from_buffer(source, offset=0) class method from
ctypes types. 'source' must expose a writeable buffer interface; the
created ctypes instance will share the internal buffer of the source
object; also it holds a reference to the source object to keep it alive.
The usual problems with the buffer interface are not hidden.
Open question:
Should there be an additional 'copy_from_buffer' class method that
accepts read-only buffer interface (as an alternative, an optional
'copy=False' parameter could be introduced)?

New submission from Fernando P?rez <fer_perez at users.sourceforge.net>:
Curses sometimes fails to correctly initialize the terminal.
Unfortunately I don't know how to reproduce the problem, it was reported
multiple times by ipython users, but I have no idea what causes it. I
finally found a workaround by making a termios call that at least
restores terminal state (see attachment), but it's just a workaround,
not a real fix.
The issue manifests itself as follows: at some point (I don't know why),
a call to curses.initscr() doesn't actually set the terminal in the
usual mode where input isn't accepted, but instead the terminal
continues accepting normal input, issuing newlines, etc. The only sign
that curses is active is that in a modern terminal, the scrollbar
changes to fill the screen. After this, calling curses.endwin(),
instead of restoring terminal state, leaves the terminal in the mode
that typically initscr() would put it in: no input is displayed,
printouts swallow end-of-line characters, etc.
When this happened in ipython sessions, we'd just suggest users call
!reset (the system command), which would restore terminal state. But
the problem is obviously in curses itself, because once this problem
appeared, running the attached script would always print 'False' for the
state condition checked there.
For now in IPython we have a workaround, but perhaps with this little
description/example, someone who knows the curses code might be able to
actually fix the real problem. If I find a reliable way to trigger the
bug, I'll add comments here indicating so.

headers
In-Reply-To: <1208608894.4.0.0735061784066.issue2658@psf.upfronthosting.co.za>
Message-ID: <1208608894.4.0.0735061784066.issue2658@psf.upfronthosting.co.za>
New submission from Christoph Schneeberger <cschnee at telemedia.ch>:
email.Header.decode_header() does not correctly deal with multiline
Headerlines.
header.py in revision 54371 (1) changes the behaviour, whereas
previously multiline headers where parsed correctly, header.py 54371
introduced a new regex part, that renders such headers invalid and they
won't be parsed as expected.
Given the following header line (doesn't matter if its parsed from a
mail or read from a string) which represents IMHO a valid RFC2047 header
line:
from email.Header import decode_header
decode_header('=?windows-1252?Q?=22M=FCller_T=22?=\r\n <T.Mueller at xxx.com>')
this will result in:
header.py (54371):
[('=?windows-1252?Q?=22M=FCller_T=22?=\r\n <T.Mueller at xxx.com>', None)]
resp. with header.py (54370):
[('"M\xfcller T"', 'windows-1252'), (' <T.Mueller at xxx.com>', None)]
Actually both seem parsed wrong, but with 54370 the result looks more
sane (the space should be IMO removed).
Once the CRLF sequence is removed from the header it works fine and all
looks as expected:
>>> decode_header('=?windows-1252?Q?=22M=FCller_T=22?= <T.Mueller at xxx.com>')
[('"M\xfcller T"', 'windows-1252'), ('<T.Mueller at xxx.com>', None)]
This problem might or might not be related to
- issue 1372770
- issue 1467619

New submission from Sylvain Fourmanoit <syfou at users.sourceforge.net>:
The textwrap module in standard library breaks hyphenated words given
the opportunity; I don't think that's absolutely obvious from the
current doc, and it's something worth mentioning.
Here is a short addition to the library reference guide.
Initial discussion started here:

While running the 2to3 script on the scons codebase, I ran into an
UnicodeDecodeError.
Attached is just the portion of the script that causes the error.
2to3 throws an error on the string regardless of whether the unicode
string literal is prepended on the front.

Message-ID: <1208642973.7.0.825847798287.issue2661@psf.upfronthosting.co.za>
New submission from David Anderson <dave at natulte.net>:
Some test cases in Lib/test/mapping_tests.py are problematic for users
wishing to test their own implementations of the mapping protocol:
- TestHashMappingProtocol.test_repr() requires the user implementations
to look like a dict when repr() is applied. It is unclear why this is
required of conforming mapping protocol implementations.
- TestMappingProtocol.test_fromkeys() cannot pass for any
implementation that uses its constructor in fromkeys(), because baddict1
defines a constructor accepting no arguments. It should accept *args,
**kwargs to be sane for user implementations that handle passing data
sources to the constructor.
- TestHashMappingProtocol.test_mutatingiteration(), for some faulty
implementations, makes the iteration degrade into an infinite loop.
Making the test more strict (eg. keeping an explicit iteration count and
failing if it goes >1) would be more helpful to buggy implementations.
These all seem like trivial issues. If it is agreed that the repr_test
should be removed from the ABC tests, I can provide a patch implementing
these three corrections.

Here's a first draft of a small addon to shutil.copytree.
This patch allows excluding some folders or files from the copy, given
glob-style patterns. A callable can also be provided instead of the
patterns, for a more complex filtering.
I didn't upgrade Doc/shutil.rst yet in this patch, as this can be done
when the change will be accepted and in its final shape I guess.

webbrowser.py ignores browsers listed in the BROWSER environment
variables if it doesn't recognize the browser. For example, if I add
"links2" to the BROWSER env var, webbrowser.py ignores it.
It is because _synthesize() doesn't know how to handle an unknown
browser. The attached patch checks if _synthesize() doesn't register a
browser and registers a GenericBrowser.
Another approach would be to register GenericBrowser in _synthesize().

New submission from Alexander Belopolsky <belopolsky at users.sourceforge.net>:
Current Doc/library/functions.rst says "The use of apply() is exactly
equivalent to function(*args, **keywords)." which is no longer correct
because f(*args, **keywords) notation allows use of an arbitrary mapping
as keywords in 2.6, but apply(f, args, keywords) does not.
I don't think changing the code to allow arbitrary mapping in apply is
worth the trouble and even mentioning this difference explicitly in the
apply() docs is probably not justified.
My recommendation is to just s/exactly equivalent/equivalent/ in the
sentence quote above.

New submission from John Arbash Meinel <john at arbash-meinel.com>:
I was performance profiling some of my own code, and I ran into
something unexpected. Specifically,
set.update(empty_generator_expression) was significantly slower than
set.update(empty_list_expression).
I double checked my findings with timeit:
With python 2.4.3:
$ python -m timeit -s 'x = set(range(10000))' 'x.update([])'
1000000 loops, best of 3: 0.296 usec per loop
$ python -m timeit -s 'x = set(range(10000))' 'x.update(y for y in [])'
1000000 loops, best of 3: 0.837 usec per loop
$ python -m timeit -s 'x = set(range(10000))' 'x.update([y for y in []])'
1000000 loops, best of 3: 0.462 usec per loop
With 2.5.1 (on a different machine)
$ python -m timeit -s 'x = set(range(10000))' 'x.update([])'
1000000 loops, best of 3: 0.265 usec per loop
$ python -m timeit -s 'x = set(range(10000))' 'x.update(y for y in [])'
1000000 loops, best of 3: 0.717 usec per loop
$ python -m timeit -s 'x = set(range(10000))' 'x.update([y for y in []])'
1000000 loops, best of 3: 0.39 usec per loop
So generally, it is about 2x faster to create the empty list expression
and pass it in than to use an empty generator.

Subject: [New-bugs-announce] [issue2675] Curses terminal resize problems
when Python is in interactive mode
In-Reply-To: <1208965300.42.0.575050740888.issue2675@psf.upfronthosting.co.za>
Message-ID: <1208965300.42.0.575050740888.issue2675@psf.upfronthosting.co.za>
New submission from Pavel Bazant <maxplanck at seznam.cz>:
When python is in interactive mode, curses does not react to resize
events properly.
test.py:
import curses
def run():
stdscr=curses.initscr()
key=0
while(key!=ord('q')):
key=stdscr.getch()
stdscr.addstr(0,0,str(stdscr.getmaxyx())+' '+str(key))
stdscr.refresh()
curses.endwin()
run()
When this is run directly, everything is ok. When it is called via
execfile() from the interactive prompt, it shows the right screen size
after the first keypress, but behaves oddly after the resize.
IMHO, the following happens:
For some reason, env. variables LINES and COLUMNS are set but they are
not reflected in the os.environ structure nor they respond to screen
size changes. If these variables are set then the ncurses library (see
man pages) uses their values instead of getting the term size via
ioctl.
The ncurses library receives a SIGWINCH and sees that LINES
and COLUMNS are set. However, their values are same as the
screen dimensions before the resize, so it is perplexed why there is
a SIGWINCH if the screen did not change and it just ungetchs an ERR
and ncurses internal structures are not changed appropriately.
>From the resizeterm man page:
"If the environment variables LINES or COLUMNS are set, this overrides
the library's use of the window size obtained from the operating
system. Thus, even if a SIGWINCH is received, no screen size change may
be recorded. In that case, no KEY_RESIZE is queued for the next call to
getch; an ERR will be returned instead."
Executing
import os
os.environ['LINES']="blah"
del os.environ['LINES']
os.environ['COLUMNS']="blah"
del os.environ['COLUMNS']
solves the problem for me.
Perhaps the problem has sth to do with python using readline
in interactive mode???

New submission from Daniel Diniz <ajaksu at gmail.com>:
[Reported by Alberto Casado Mart?n [1]]
Message.get_content_type() hangs when very large values are split by the
regex:
ctype = paramre.split(value)[0].lower().strip() #line 439
paramre comes from line 26:
paramre = re.compile(r'\s*;\s*')
Unless the full fledged parser cited in the comment before line 26 is in
the works, I suggest splitting the string by ";" to get exactly the same
behavior in a more reliable way.

apply when function uses PyArg_ParseTuple

Message-ID: <1209031286.77.0.288825613693.issue2677@psf.upfronthosting.co.za>
New submission from Ludovico Gardenghi <garden at acheronte.it>:
(It seems strange to me that this issue hasn't been raised in the past,
maybe I just failed to find it in the BTS. In that case please excuse me
and please point me to the original discussion.)
The Language Reference, section 5.3.4, states that, for every callable
object:
"[...] If keyword arguments are present, they are first converted to
positional arguments, as follows. First, a list of unfilled slots is
created for the formal parameters. [...] Next, for each keyword
argument, the identifier is used to determine the corresponding slot (if
the identifier is the same as the first formal parameter name, the first
slot is used, and so on). [...]"
This is not true if the function is defined using the C function
PyArg_ParseTuple, and this happens a lot in the standard library. I
discovered it trying to call os.open("filename", flag=os.O_RDONLY), just
to make an example. In this case it seems useless to specify the
keyword, but I have to write a generic "wrapping" function that takes a
function name and its arguments (as keyword arguments) and call the
original function after having changed the content of some of the arguments.
Apart from the reason, I believe that this behavior is inconsistent with
the language definition and should be fixed. I'm very new to Python, but
maybe the format string of ParseTuple should be extended in order to
accept also the name of the positional arguments? Or something like
ParseTupleAndKeywords should be used instead?
I tried only on Python 2.4 and 2.5 but I took a look at the source code
of 2.6 and 3.0 and I believe the issue is still there.

New submission from Jim Jewett <jimjjewett at users.sourceforge.net>:
feedparser defines four regexs for end-of-line, but two are redundant.
NLCRE checks for the three common line endings.
NLCRE_crack also captures the line ending.
NLCRE_eol also adds a $ to ensure it is at the end.
NLCRE_bol ... is identical to NLCRE_crack.
It should either use a ^ to insist on line-start, or be explicitly the
same. (e.g., NLCRE_bol=NLCRE_crack.) (It gets away with not listing the ^
because the current code only uses NLCRE_bol.match.
(Actually, if the regexes are considered private, then the current code
could just use the bound methods directly ... setting NLCRE_bol to the
.match method, NLCRE_eol to the .search method, and NLCRE_crack to the
.split method.)

Message-ID: <1209054598.56.0.869643516556.issue2680@psf.upfronthosting.co.za>
New submission from Carlos Scheidegger <cscheid at sci.utah.edu>:
When creating ctypes.Structure classes dynamically, there's a gotcha.
_fields_ is final, but it takes a list that can be appended to. I'm not
sure this is a bug, but I would argue it is a lot more surprising than
it could be:
Python 2.5.2 (r252:60911, Apr 21 2008, 11:17:30)
[GCC 4.2.3 (Ubuntu 4.2.3-2ubuntu7)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import ctypes
>>> class Foo(ctypes.Structure):
... _fields_ = [('dim', ctypes.c_int)]
...
>>> x = Foo()
>>> x.dim = 1
>>> x.dim = '123' # This is ok, and expected
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: an integer is required
>>>
>>>
>>> class Bar(ctypes.Structure):
... pass
...
>>> x._fields_ = []
>>> x._fields_.append(('dim', ctypes.c_int))
>>> x = Bar()
>>> x.dim = '123' # This, however, is strange
>>>
This was somewhat foreseen, since _fields_ is final:
>>> class Baz(ctypes.Structure):
... pass
...
>>> Baz._fields_ = []
>>> Baz._fields_ = [('dim', ctypes.c_int)]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: _fields_ is final
Would it not make sense for _fields_ to require a tuple, so that it
cannot be mutated? I realize this is a big change. Currently, ctypes
accepts tuples as the input to _fields_. Maybe a warning should be
issued when a list is assigned to _fields_?

Octal literals containing an 8 or a 9 should raise a SyntaxError, but 8 ist
accepted as the first character of such a literal (e.g., 0o8 or 0o876, but
not 0o678). Those literals evaluate to 0.0.
The fix for this is trivial, a patch against current SVN (r62479) is
attached.

About same as problem in 2.4 Issue1470422 closed without a test case on
MacOS X/Python 2.4.
Also same as
http://mail.python.org/pipermail/python-bugs-list/2004-July/024111.html
and so on back for years.
What happens:
chasm at chasm-laptop:~/py$ cat x.py
import logging
logging.basicConfig(level=logging.DEBUG,
format="%(levelname)s:%(pathname)s:%(lineno)d:%(message)s")
from logging import debug
if __name__ == "__main__":
debug("Hello")
chasm at chasm-laptop:~/py$ python x.py
DEBUG:logging/__init__.py:1327:Hello
What should happen:
It should print DEBUG: x.py:3:Hello
Why it fails:
Because logging guesses that the right sys._getframe(level) should be
level 3 in __init__.py:71, in currentFrame
if hasattr(sys, '_getframe'): currentframe = lambda: sys._getframe(3)
What should happen:
It shouldn't guess. In Python 2.5, the lambda might count. In any
case, the level is off by one (4). I suggest that it get set by walking
up the stack from until it exits the stack frame.

New submission from A.M. Kuchling <lists at amk.ca>:
On my MacOS 10.4.11 machine, the example SSL server and client in the
documentation don't work, and they fail with a mysterious error 0. The
attached tarball contains my slightly-modified version of the scripts
and the test key/cert I'm using.
When I run the server, and then the client, the output of the server is:
amk at amk:~/source/p/python$ ./python.exe server.py
Waiting for connection...
Connection received from ('127.0.0.1', 61915)
Traceback (most recent call last):

ssl.SSLError: [Errno 8] _ssl.c:429: EOF occurred in violation of protocol
And the client is:

Traceback (most recent call last):
File "client.py", line 10, in <module>
ssl_sock.connect(('', 9000))

amk at amk:~/source/p/python$
The error 0 is very puzzling.
Perhaps I generated the key and cert incorrectly, and parsing them is
failing in this strange way?

New submission from Alexander Belopolsky <belopolsky at users.sourceforge.net>:
Attached patch makes range objects precompute their length on creation.
This speeds up indexing and len at the expense of a small increase in
range object size. The main benefit, however is that unsupported length >
sys.maxsize is detected early and confusing OverflowError from len(r) or
r[i] is avoided.
See discussion starting at http://mail.python.org/pipermail/python-

IIUC, the bytes object should be immutable (in contrast to bytearray).
But PyObject_FromWriteBuffer() does not fail.
It seems that the attached patch fixes it; however there are lots of
failures in the testsuite with the patch - even 'memoryview(b"abcd")' fails.

Message-ID: <1209166587.6.0.537428901937.issue2693@psf.upfronthosting.co.za>
New submission from Greg Couch <gregcouch at gmail.com>:
IDLE and Tk 8.5 don't well work together for both Python 2.5 and 2.6a
(SVN version). The reasons are related but different.
In Python 2.5, you can't select any text in the IDLE window and whenever
a calltip is to appear, you get a backtrace ending with "invalid literal
for int() with base 10: '(72,'". That comes from an interaction between
WidgetRedirector's dispatch function and _tkinter. The Text widget's
bbox method returns a tuple of ints, the dispatch function isn't
monitoring bbox, so it returns the tuple as is to _tkinter, where
PythonCmd converts the tuple to a Python string, not a Tcl list, so when
Tkinter sees the string, it can't convert to a tuple.
The Python "2.6a2" SVN version of _tkinter fixes that bug but exposes
others (Ikinter.py, tupleobject.c), so I've attached a simple patch for
Python 2.5. The SVN version of idle appears to work, so this patch
should only be on the 2.5 branch.

Hi,
I wanted to build a msi using the build_msi distutils command for one of
my package, but at some point, it fails, at the function make_id, at
line 177 in mstlib/__init__.py, for a file named aixc++.py. The regex
indeed refuses any character which is not alphanumeric: is msi itself
really that strict, or could this check be relaxed ?

Message-ID: <1209217597.75.0.0893619687269.issue2697@psf.upfronthosting.co.za>
New submission from andrew cooke <andrew at acooke.org>:
I am seeing some odd behaviour with logging which would be explained
if loggers that are not defined explicitly (but which are controlled
via their ancestors) must be created after the logging system is
configured via fileConfig().
That's a bit abstract, so here's the problem itself: I define my log
within a module by doing
import logging
log = logging.getLogger(__name__)
Now typically __name__ will be something like "acooke.utils.foo".
That happens before the application configures logging, which it does
by calling logging.config.fileConfig() to load a configuration.
If I do that, then I don't see any logging output from
"acooke.utils.foo" (when using "log" from above after "fileConfig" has
been called) unless I explicitly define a logger with that name.
Neither root nor an "acooke" logger, defined in the config file, are
called.
One way to handle this is to make creation of module-level Loggers
lazy, and make sure that logging initialisation occurs before any
other logging is actually used (which is not so hard - just init log
at the start of the application).
Of course, there's a performance hit...
For example:
class Log(object):
def __init__(self, name):
super(Log, self).__init__()
self._name = name
self._lazy = None
def __getattr__(self, key):
if not self._lazy:
self._lazy = logging.getLogger(self._name)
return getattr(self._lazy, key)
and then, in some module:
from acooke.util.log import Log
log = Log(__name__)
[...]
class Foo(object):
def my_method(self):
log.debug("this works as expected")

If you pass csv.reader() a filename as its first argument:
csv.reader('filename')
instead of a file object like you're supposed to, you don't get an error.
You instead get a reader object which returns the characters which make up
the filename.
Technically, this is not a bug, since the documentation says, "csvfile can
be any object which supports the iterator protocol and returns a string
each time its next method is called", and a string meets that definition.
Still, this is unexpected behavior, and is almost certainly not what the
user intended. It would be useful if a way could be devised to catch this
kind of mistake.

Message-ID: <1209282789.34.0.562999954252.issue2702@psf.upfronthosting.co.za>
New submission from Daniel Darabos <darabos.daniel at gmail.com>:
The documentation[1] says:
Trying to pickle a highly recursive data structure may exceed the
maximum recursion depth, a RuntimeError will be raised in this
case. You can carefully raise this limit with sys.setrecursionlimit().
The lightweight pickle module handles this problem correctly (in that it
raises a RuntimeError), but cPickle sometimes raises KeyError instead,
or just silently terminates the interpreter (=crashes). (I have not been
able to pinpoint what it depends on. In the attached example I get
silent termination, but if instead of lists I use sets to describe the
connections, I get the RuntimeError.)
This was mentioned in issue 2480, but that has now been changed to a
feature request to eliminate recursion altogether. That may have a lower
priority, but this crash can be hard to diagnose in a complex
application, and I am not sure if sys.setrecursionlimit() affects
cPickle behavior (I guess not).

"SimpleXMLRPCDispatcher.__init__ used to take a single argument
(self) in python2.4 and now it takes three. The two new arguments
need to get default values or else this breaks backwards
compatibility badly."
while SimpleXMLRPCDispatcher is not described as part of the interface,
it is mentioned in the docs. The fix seems to be easy. Ok for trunk and
the branch?

New submission from Roger Serwy <roger.serwy at gmail.com>:
See attached diff file. Patching PyShell.py Version 1.2.1
PyShell ignores letter/number key presses when the cursor is not on the
command line. Instead it should redirect any letter/number key presses
to the command line. (Changed ModifiedUndoDelegator)
Also, up/down arrow presses should scroll through history when the
cursor is on the command line. But when the cursor is not on the command
line, the arrow keys should move around the PyShell window. (Added new
bindings with conditional logic)

Message-ID: <1209323334.77.0.104236998001.issue2705@psf.upfronthosting.co.za>
New submission from Jean-Paul Calderone <exarkun at divmod.com>:
In Python 2.5 and earlier, the `showwarning? function in the `warnings?
module has this signature:
def showwarning(message, category, filename, lineno, file=None):
In trunk (and presumably what will become Python 2.6), this has become:
def showwarning(message, category, filename, lineno, file=None,
line=None):
`showwarning? is documented as a hook which libraries or applications
may override in order to control how warnings are reported. The
addition of a new parameter to the function and the change to related
code to call it with an argument for that new parameter means that
libraries and applications which replaced it will not work without
modification on Python 2.6. Instead, a `TypeError? will be raised when
a warning is emitted.
I suggest restoring the previous signature for `showwarning? and adding
a new (perhaps preferred) API for showing a warning with the extra
information available. It may also make sense to emit a deprecation
warning when an overridden old-style `showwarning? is found.

Subject: [New-bugs-announce] [issue2706] datetime: define division
timedelta/timedelta
In-Reply-To: <1209330247.56.0.71148380164.issue2706@psf.upfronthosting.co.za>
Message-ID: <1209330247.56.0.71148380164.issue2706@psf.upfronthosting.co.za>
New submission from webograph <webograph at eml.cc>:
i suggest that division be defined for timedelta1/timedelta2, in that
sense that it gives how many times timedelta2 fits in timedelta1 (ie the
usual meaning of division), using integer arithmetics for floor division
(//) and returning float for truediv (/ after `from __future__ import
division`)
use case
--------
aside from the obvious how-many-times-does-a-fit-into-b, this solves the
issue of having individual methods for conversion to a number of
seconds, hours, days or nanocenturies (as described in #1673409).
example:
from datetime import timedelta
duration = timedelta(hours=1.5, seconds=20)
print "Until the time is up, you can listen to 'We will rock you' %d
times."%(duration//timedelta(minutes=5, seconds=3))
import time
time.sleep(duration/timedelta(seconds=1))
history
-------
this issue follows a discussion on python-list, re-initiated by [1].
there have previously been similar feature requests on datetime, most of
which have been rejected due to ambiguities (e.g. [2]), conflicts with
time_t or issues with time zones.
the only issue i've seen that can be relevant here is the
integer-vs-float discussion, which is here handled by floordiv (//) and
truediv.
patch
-----
i've written a patch against svn trunk revision 62520.
it uses function pointers to reduce code duplication; in case this
inappropriate here, i also have a pointerless version.
i familiar with c but not experienced, especially with the python ways
of writing c. most of the code is just adapted from other functions in
the same files, so it is probably, but should nevertheless checked with
special care.
i've also added test, but am not sure what has to be tested and what not.
compatibility
-------------
only cases in which division would fail without the patch are changed.
this will be a problem if (and only if) someone divides unknown objects
and waits for TypeError to be raised.
such behavior is probably rare.

Hi all.
I'w been looking for an answer to this.
If I use IDLE for som "just fore fun" programming and then exit, I have
to "kill" IDLE, dispite theres nothin "running" persay, then when i
start IDLE again I get too error messages popping up:
1: Socket Error: Connection refused
2: IDLE's subprocess didn't make connection. Either IDLE can't start a
subprocess or personal firewall is blocking the connection.
The code written in IDLE that triggers the problem can be something
simple like:
>>> a = 'hello world'
>>> print a
I have to reboot to get past the error.
I'm only getting the error when running vista and xp theres no problom
in any of the other systems i'v tried (mainly linux)
I should mention that the error dosn't come every time I "kill" IDLE, I
would say about every 3rd run, or there about.
I'v tried removeing/killing windows owen firewall and then running IDLE
but with the same result.
Like I said, i been look around fore a "fix" fore this but havent found
any...
If I have made a "double post" please let me know and remove this
post....

tk.rst tells, among other things:
"`Tkinter`'s chief virtues are that it is fast, and that it usually comes
bundled with Python. Although it has been used to create some very good
applications, including IDLE, it has weak documentation ..."
Why does it say Tkinter has weak documentation ? There is a printed book
("Python and Tkinter Programming"), several online tutorials and
references, there is a wiki too, the mail list and possibly something
else I've missed.

patch adds tempfile.mkstempf to remedy that.

This patch causes struct *compiling to be passed around to all of the
ast helper functions. Since most functions already take it, this makes
it more consistent as a whole. Also, the filename (from
compiling->c_filename) is needed to issue warnings with PyErr_WarnExplicit.

New submission from Paul Winkler <pw_lists at slinkp.com>:
A comment in unittest.py says "these functions should be considered
obsolete". But I've seen a lot of code in the wild still using
unittest.makeSuite(MyTestCase)... in fact it's used frequently in the
python standard library tests.
And I don't see a replacement for this use case: given a subclass of
TestCase, conveniently turn all its test* methods into a suite. How are
we supposed to do that now?
Either makeSuite should be documented, or a suitable replacement should
be provided and documented.

New submission from Sandeep Sabnani <sandeepsabnani at gmail.com>:
Section 4.4 on page http://docs.python.org/tut/node6.html has a for loop
which uses the range function. However, the displayed output of that
loop is not correct. I ran the same code and got the output as follows:
3 is a prime number
4 = 2 * 2
5 is a prime number
5 is a prime number
5 is a prime number
6 = 2 * 3
7 is a prime number
7 is a prime number
7 is a prime number
7 is a prime number
7 is a prime number
8 = 2 * 4
9 is a prime number
9 = 3 * 3
Can this be corrected in the tutorial as it can be confusing for a
python newbie!
Thanks!

New submission from Thomas Lee <tom at vector-seven.com>:
The current code in Parser/asdl.py doesn't handle syntax errors very
well. A minor problem to be sure, since the net result is the same (i.e.
build fails), but the error message being displayed is entirely
unhelpful to the developer.
The attached patch will display the error message as was seemingly intended.
This probably affects earlier versions (including python-trunk), but I
haven't tested.

New submission from Abhik Shah <abhikshah at gmail.com>:
The autoclass directive adds the class constructor's argspec to the header and shows the class docstring
below it but doesn't add the constructor's docstring. I usually use the class docstring to describe the
class and the constructor's docstring to describe the constructor arguments so if the constructor argspec
is being shown, I would expect the description of it to be included below.

I don't know how other people would expect autodoc to work so maybe this behavior could be controlled by
a config param?
