Subject: [New-bugs-announce] [issue4477] Speed up PyEval_EvalFrameEx when
tracing is off.

New submission from Jeffrey Yasskin <jyasskin at gmail.com>:
Tracing support shows up fairly heavily an a Python profile, even
though it's nearly always turned off. The attached patch against the
trunk speeds up PyBench by 2% for me. All tests pass. I have 2
questions:
1) Can other people corroborate this speedup on their machines? I'm
running on a Macbook Pro (Intel Core2 processor, probably Merom) with
a 32-bit build from Apple's gcc-4.0.1. (Apple's gcc consistently
produces a faster python than gcc-4.3.)
2) Assuming this speeds things up for most people, should I check it
in anywhere besides the trunk? I assume it's out for 3.0; is it in for
2.6.1 or 3.0.1?

The branch should be predicted accurately either way, so there are 2
things that may be contributing to the performance change.
First, adding the global caching variable halves the amount of memory
that has to be read to check the prediction. The memory that is read
is still read one instruction before it's used, but adding a local
variable to read the memory earlier doesn't affect the performance.
Without the global variable, the compiler puts the tracing code
immediately after the if; with the global, it moves it away and puts the
non-tracing code immediately after the first test in the if. This
may affect branch prediction and may affect the icache. I tried using
gcc's __builtin_expect() to ensure that the tracing code is always
out-of-line. This moved it much farther away and cost about 1% in
performance (i.e. 1% instead of 2% faster than "before"). I don't know
why the __builtin_expect() version would be slower. If anyone feels
inspired to test this out on another processor or compiler version,
let me know how it goes.

shutil.Error: `/tmp/f` and `/tmp/f` are the same file
The Python 3 docs at
http://docs.python.org/dev/3.0/library/shutil.html#module-shutil
mention that copyfile can raise IOError, but they omit to mention that
copyfile can also raise shutil.Error.
Also, just out of interest, I notice that Sphinx now supports the
':raises:' field. Are there any plans for the Python documentation to
start using it?

Now that #4389 is fixed, it would be nice if the bdist_msi and
bdist_wininst created installers could use the same Python icon for
their uninstallers.
Note that both commands create installers that are prefixed with the
Python version, so there already is a tight binding between the Python
interpreter itself and the extensions installed using those installers.
Alternatively, perhaps we could add a way to set the icon via command
options.

Under Debian/Lenny/i486, I install python3.0rc3.
After untar the Python3.0rc3 package, I replace in the configure
"/usr/local" by "/usr". After I do :
"configure --with-pydebug --with-doc-strings --enable-shared
--enable-profiling --enable-ipv6 --with-threads --with-tsc ; make"
The result during make is :
"Failed to find the necessary bits to build these modules:
_dbm
To find the necessary bits, look in setup.py in detect_modules() for the
module's name."
The release of the dbm library is :
libgdbm-dev 1.8.3-3 GNU dbm database routines (development files)
The header for dbm : "_gdbmmodule.c" request "gdbm.h", and is here
"/usr/include/gdbm.h"
The "Modules/_dbmmodule.c" use :
#include <gdbm/ndbm.h>" ... #include <ndbm.h> ...
but I have only "/usr/include/gdbm-ndbm.h"
Can you patch the "_dbmmodule.c" to use it ?

Message-ID: <1228199205.8.0.509541493061.issue4484@psf.upfronthosting.co.za>
New submission from Shaddy Baddah <shaddy_baddah at hotmail.com>:
I note that using the struct module, a user can specify if number items
of the format are to be interpreted as either big or small endian.
However the format specifier can only accept one indicator character at
its first character to apply for all number items in it. e.g:
"<HI" specifies that both the unsigned short and unsigned int are to be
interpreted as little endian values.
It would be nice to be able to instead do "<>HI" where the first '<'
character indicates the default endianess (for compatibility purposes)
and then the second '>' character indicates that the unsigned short
should be interpreted as big endian. The unsigned int defaults to small
endian as per the first character.

Here's how I set up my computer, for multiple versions. Now to change
the "default", I just use the assoc command to change the association
for .py to one of the three listed ftypes. Simple and quick.
c:\>ftype Python25.File
ftype Python25.File
Python25.File="C:\Python25\python.exe" "%1" %*
c:\>ftype Python26.File
ftype Python26.File
Python26.File="C:\Python26\python.exe" "%1" %*
c:\>ftype Python30.File
ftype Python30.File
Python30.File="C:\Python30\python.exe" "%1" %*
c:\>assoc .py
assoc .py
.py=Python25.File
It would be nice if the ftypes were version specific as created by the
installer; IIRC, I created the above three from the ftype Python.File as
I installed each version.
The Python.File could still be created by default, and could still
reflect the last temporally installed version of Python... but by
documenting the version specific ftypes, the user could still switch
among versions.
I suppose there is a question of if the version should contain two or
three parts, i.e. Python253.File; and if the version should be separated
such as Python2.5.3.File; the above worked for me for the moment, but
some thought might reveal a more useful technique.
It might even be appropriate for a Python version to create 3 ftypes,
such that version N.M.O creates ftypes named PythonN.File,
PythonN.M.File, and PythonN.M.O.File. All but the most specific one
would be subject to change when additional versions are installed. If M
or O are zero, they should probably still be specified (as zero) in a
scheme like this, so that there would be a solid way of referring to all
the specific versions.

__context__ are both set on the current exception.
=================
>>> try:

... except:

KeyError
The above exception was the direct cause of the following exception:
Traceback (most recent call last):
File "<stdin>", line 2, in <module>
IOError
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "<stdin>", line 4, in <module>
AttributeError
=================
I'm not entirely sure what *should* be displayed here (the code I typed
in is admittedly bizarre), but what is currently being displayed
definitely isn't right.

New submission from maxua <ischenko at gmail.com>:
When using MIME email package you can specify "utf8" as the encoding. It
will be accepted but it is not rendered correctly in some MUA. E.g. Mac
OS X Mail.app doesn't display it properly while Google Gmail does.
It is confusing since Python itself happily understands both utf8 and utf-8.
The patch adds "utf8" as an alias to "utf-8" encoding which means user
won't need to think twice.
Test case:
from email.MIMEText import MIMEText
msg = MIMEText(u'\u043a\u0438\u0440\u0438\u043b\u0438\u0446\u0430')
msg.set_charset('utf8')
print msg.as_string()

New submission from Martin Meredith <mez at ubuntu.com>:
I'm a new python user (developing in python) and I recently had a
discussion with someone that my main issue with python is finding where
the functions are that I need to use.
An example (probably not the best) - I need to split a filename so that
I can have the extension and the rest of the filename seperate. Fine.. I
google, and I get the following page:-
http://www.python.org/doc/2.5.2/lib/os-path.html
Now, that lists the function splitext - which is what I need - but it's
not clear on the page where that function is located (os.path)
I think that this should be made clearer somehow - as it seems to me
that you have to go through about 3 pages trying to work out where it is
(or work it out from the URL) - which isn't very intuitive, espescially
for a new user, who doesn't actually know where all the functions exist.

New submission from Mart S?mermaa <mrts at mrts.pri.ee>:
Race condition in the rmtree function in the shutils module allows local
users to delete arbitrary files and directories via a symlink attack.
See also http://bugs.debian.org/286922
Attack:
---
# emulate removing /etc

$ mkdir /tmp/attack

New submission from John J Lee <jjlee at users.sourceforge.net>:
The fix for #900744 tried to close the connection when a bad chunk
length was received. The comment inserted with that fix "close the
connection as protocol synchronisation is probably lost" is incorrect:
self.close() in _read_chunked does not close the connection. You have
to call HTTPConnection.close() to close the connection.
So:
* The comment is incorrect, and should be removed or fixed. I guess
the self.close() should stay.
* It's probably a bug that it doesn't result in the connection being
closed. I guess a fix for that would be for the HTTPResponse to set
some state on itself that HTTPConnection can query so that
HTTPConnection can close itself the next time somebody tries to do
something with the connection.

Message-ID: <1228250772.41.0.047917224679.issue4493@psf.upfronthosting.co.za>
New submission from John J Lee <jjlee at users.sourceforge.net>:
As required by RFC 2616 section 3.2.2, for all HTTP requests sent by
urllib2, the path component of the URI should be normalized to "/"
before the Request-URI derived from it gets passed to httplib (or
something functionally equivalent to that). This was fixed in one case
in #2464, but the fix is in the wrong place, since it's a general
problem not specific to redirects. See the longer discussion here:
http://bugs.python.org/msg76736
(hmm, let's see if I can just say msg76736 and get a hyperlink)
Example:
import urllib2
urllib2.urlopen("http://python.org?spam")
Expect: sends "/?spam" in request line.
Got: sends "?spam" in request line.
Probably should be fixed by making Request.get_selector() return the
normalized URI reference (with the slash always present). When fixing,
remember that the Request-URI of RFC 2616 (returned by .get_selector())
is sometimes a relative reference, and sometimes a URI (in RFC 3986's
terminology).

When building python 2.6 with Py_NO_ENABLE_SHARED compilation fails on

r54137 replaced a comment in urllib2.py with a misleading comment. The
comment now implies the .insort() in question achieves the goal
specified in the new comment. That's not true, which was the reason the
original comment was there in the first place.
At least replace the comment with the original comment. Alternatively,
(correctly) resolve the question in the original comment somehow (for
example by removing the .handlers attribute -- but since .handlers is
misnamed in not having an initial underscore, it may have tempted people
to use it, even though it's undocumented, hence private).

Should / must we do anything about the issue? At least Python builds
with a C89 compiler except of ssl and socket module. Those modules
include non C89 compliant header files from the OS (bluetooth and tpic).

New submission from Giampaolo Rodola' <billiejoex at users.sourceforge.net>:
I discovered that some pyftpdlib [1] tests fail when using poll()
instead of select().
The problem is in asyncore.readwrite() function which erroneously calls
handle_read_event() in case of a POLLPRI event.
The patches modify readwrite() function so that:
- POLLPRI is now treated as synonym for "there is urgent data to read"
so handle_expt_event() is called.
- POLLHUP, POLLERR and POLLINVAL are now treated as synonyms for "the
connection has been closed" (Twisted behaves exactly the same) so
handle_close() is called.
Both pyftpdlib and asyncore tests passed on Linux Debian Etch and
FreeBSD 7.0-RC1.

At the moment there is no way of getting the current pre_input_hook out
of the readline module, so applications cannot set_pre_input_hook
without possibly over-writing users settings (or other parts of the
applications settings) I have attached a patch that implements this
functionality.
It is probably not very useful in many situations, but I am now using it
to maintain my normal custom auto-indenting python prompt in a library
that allows me to edit arbitrary strings using readline. A better way to
implement this might be to

spaces in path to output/src files

New submission from Brian Thorne <hardbyte at gmail.com>:
I found this bug when using scipy's weave and having some inline C/C++
code. Weave uses distutils to compile the source in its own directory,
python was installed under "program files". Unfortunately it doesn't
seem to handle spaces in the path to either the output or the temporary
source files.
I checked that this was the only problem by copying the weave directory
from site-packages and put it in another directory without spaces in the
path - weave and distutils then worked fine.
I then tried the g++ command seen in the stack trace at the command line
and got the same error - so altered the command by correctly quoting the
-c "path/to source/a.c" and the -o objects.
This worked so set out changing it in distutils.
The two files I altered were unixcompiler.py (surprising as I am under
windows!) and cygwinccompiler.py
This was clearly an older stable build so I checked out the python trunk
r67510 on windows (32bit), made a patch, and tested with my weave
dependant code.
(I am not familiar enough with distutils to make a standalone test).
The same method to cause a problem has the same effect in ubuntu - the
build directory seems to default to users home, but as the source path
has a space in it g++ gets confused.

New submission from David W. Lambert <lambertdw at corning.com>:
http://docs.python.org/dev/3.0/reference/datamodel.html#special-lookup
(After fixing the link to http://docs.python.org/3.0 at http://www.python.org/doc/ (and likewise the http://docs.python.org/whatsnew/3.0.html link.)...
The comment that __getattribute__ is "Called unconditionally to
implement attribute accesses for instances of the class" gave me hope
that some combination of "meta" "super" and "sub" might let me access
__getattribute__ for expression eval('obj + another_object') despite the
special notes. I realize now the truth is that
"__getattribute__ is NEVER accessible in pure python code when the code
uses the syntax of a unary or binary operator such as a+b, ~a, len(a)."
See most of the functions in this manual section.
Also name hash, which doesn't find much explicit use but could well be
the most used python functionality. Find a smooth way to replace my
NEVER since code can obviously access __getattribute__ from the special
function.
Thank you, and great work!

On the 3.0 release page (http://python.org/download/releases/3.0/) the

However, the doc pages there show the version documented to be "Python
v3.1a0". There's even a link called "What's new in Python 3.1?" that
doesn't work.
Could it be that the pages currently under

New submission from Bobby Xiao <nneonneo at gmail.com>:
Under http://docs.python.org/dev/3.0/whatsnew/3.0.html#new-syntax, on
the last two points, it says
"# New binary literals, e.g. 0b1010 (already in 2.6).
# Bytes literals are introduced with a leading b or B, and there is a
new corresponding builtin function, bin()."
I believe it should read
"# New binary literals, e.g. 0b1010 (already in 2.6), and there is a new
corresponding builtin function, bin().
# Bytes literals are introduced with a leading b or B, and there is a
new corresponding builtin function, bytes()."
or something along those lines, as "bin" is for binary literals, not
bytes literals, and "bytes" is for bytes literals.

New submission from Paul Goins <general at vultaire.net>:
Just got Python 3.0 final on Windows and was testing out IDLE, and it's
having some issues.
Specifically:
* Options -> Configure IDLE..., General Tab:
Change Default Source Encoding from None to UTF-8
* Create a new python file and enter a print command
containing Japanese text. Save it. (Saves to UTF-8.)
* Press F5 to run the script. IDLE crashes.
However, if the default encoding is left as "None", and you create a new
file and allow IDLE to save it as cp932, then it runs with no problem
through IDLE.
Straight Python on a command line is not affected and reads the UTF-8
files perfectly fine.
Attached is a script which crashes IDLE every single time I run it.
Thanks.

New submission from Matt Kraai <kraai at ftbfs.org>:
When I try to build Python 3.0 on QNX 6.3.2, the build has the following
error:
gcc -c -fno-strict-aliasing -DNDEBUG -g -O3 -Wall -Wstrict-prototypes
-I. -IInclude -I./Include -DPy_BUILD_CORE -o Python/pythonrun.o
Python/pythonrun.c
Python/pythonrun.c: In function `Py_InitializeEx':

Python/pythonrun.c:180: (Each undeclared identifier is reported only once
Python/pythonrun.c:180: for each function it appears in.)
...
make: *** [Python/pythonrun.o] Error 1
LC_CTYPE is defined in locale.h, which isn't included because
HAVE_LANGINFO_H isn't defined because QNX 6.3.2 doesn't provide
langinfo.h. The setlocale call in the trunk is guarded by
HAVE_LANGINFO_H, so maybe that should be done here as well.
Once this error has been fixed, the following error occurs:
gcc -c -fno-strict-aliasing -DNDEBUG -g -O3 -Wall -Wstrict-prototypes
-I. -IInclude -I./Include -DPy_BUILD_CORE -DPYTHONPATH='":plat-qnx6"' \

-DVPATH='""' \
-o Modules/getpath.o ./Modules/getpath.c
./Modules/getpath.c:132: invalid initializer
...
make: *** [Modules/getpath.o] Error 1
This version of GCC apparently cannot handle wchar_t array initializers.
This can be worked around by changing the type of lib_python to a
wchar_t pointer instead.

New submission from Terry J. Reedy <tjreedy at udel.edu>:
C.l.p poster reported that 3.0 file.read is orders of magnitude slower
than with 2.5 (but confused issue with buffer = 0). Jerry Hill reported
"Here's a quick comparison between 2.5 and
3.0 on a relatively small 17 meg file:
C:\>c:\Python30\python -m timeit -n 1
"open('C:\\work\\temp\\bppd_vsub.csv', 'rb').read()"
1 loops, best of 3: 36.8 sec per loop
C:\>c:\Python25\python -m timeit -n 1
"open('C:\\work\\temp\\bppd_vsub.csv', 'rb').read()"
1 loops, best of 3: 33 msec per loop
That's 3 orders of magnitude slower on python3.0!"
I verified this informally on WinXP by opening and then reading
Doc/Pythonxy.chm (about 4 megs) -- an eye blink versus 3 seconds,
repeated. Even the open seemed slower but I did not time it.
>>> f=open('Doc/Python30.chm','rb')

New submission from jeff deifik <jeff at jeffunit.com>:
I compiled python 3.0 on a cygwin platform.
Here is my modest function:
def List_to_String(lis):
# return str.join(lis, '') # This is fast, but seems broke in 3.0
s = '' # This is really slow, but works in 3.0
for l in lis: s = s + l
return s
Here is my test case:
def test_List_to_String(self):
inp = ['f', 'r', 'e', 'd', ' ', 'i', 's']
out = 'fred is'
self.assertEqual(jefflib.List_to_String(inp), out)
Here is what happens when I try to run the commented out version (the
one with the join):
ERROR: test_List_to_String (__main__.TestJefflibFunctions)

TypeError: descriptor 'join' requires a 'str' object but received a 'list'
Of course, it worked fine in python 2.6.
I am baffled.

Message-ID: <1228425636.98.0.0937158312047.issue4536@psf.upfronthosting.co.za>
New submission from Laszlo <laszlok2 at gmail.com>:
>>> range(1.0, 0, 1)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'float' object cannot be interpreted as an integer
>>> range(1.0, 0, -1)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
SystemError: NULL result without error in PyObject_Call
The error here is that range() does not accept float arguments. However
in the second example the step argument is -1. Since -1 is also used to
indicate a integer overflow, when processing the step argument, it is
assumed that (step == -1 && PyErr_Occurred()) means that an overflow
occured.
However in this particular case, step is supposed to be -1, and the
error is a TypeError from the previous argument which is a float. The
error is then cleared and step is rounded to fit inside an integer.
start = PyNumber_Index(start);
stop = PyNumber_Index(stop);
step = validate_step(step);
if (!start || !stop || !step)
goto Fail;
Now in the above code start is NULL, and the if statement checks for
this, and goes to Fail which return NULL. But no error condition is set
(it was cleared before) and NULL raises a SystemError.
My patch changes three things:
* In validate_step(): remove unnecessary 'step = PyNumber_Index(step)',
because this PyNumber_Index conversion is already done in the next line
by PyNumber_AsSsize_t().
* In validate_step(): don't clear the error is the result is -1. The
overflow error is already cleared by PyNumber_AsSsize_t(), and any other
errors should remain.
* In range_new(): check for NULL values before calling validate_step(),
because unlike for the other arguments where we call PyNumber_Index(),
calling validate_step() may clear the previous error.

It would be useful if ctypes included limiting constants for the various

Maybe it does and I just missed just didn't see it in the docs?

Subject: [New-bugs-announce] [issue4539] askdirectory() in
tkinter.filedialog is broken

Message-ID: <1228431916.65.0.748760497567.issue4539@psf.upfronthosting.co.za>
New submission from Chad Spratt <internet2.0 at gmail.com>:
Calls to tkinter.filedialog.askdirectory() throw a KeyError if any of
the options (title, text, bitmap, default, strings) are not provided.
Previously saying "askdirectory()" with no arguments would open a file
browser window. Since all other functions in filedialog still function
with no arguments this seems like an error. (Actually askopenfiles()
seems to be broken too, saying "IOError: [Errno 2] No such file or
directory: '{'")

New submission from Zach Hirsch <zhirsch at umich.edu>:
I've found that having a way to strip a leading substring from a string
is convienent. I've also gotten bitten by the fact that str.strip takes
a sequence of characters to remove from the beginning -- not a full string.
I've attached a patch that implements lstrips, rstrips, and strips on
str, unicode, and as methods in the string module. I'm not particularly
attached to the names.
Please consider this patch for inclusion in Python. Thanks!

Doing the following (more info than necessary in case I'm doing
something weird):
def odd(n):
return n % 2
x = (1, 2, 3, 4, 5)
y = filter(odd, x)
list(y)
list(y)
Will correctly build a list from y and return [1, 3, 5] on the first
call to list(), but will return an empty list thereafter. y still
identifies itself as a filter object, but you either can't coerce it to
anything else or the value of the filter object is reset (I don't know
how to tell the difference yet).
The other container constructors (set, tuple, etc.) seem to have the
same behaviour.

>From textwrap.py: 46863 2006-06-11 19:42:51Z tim.peters
The __all__ define in this module is missing the helper function 'dedent'.
This causes pydoc to not the list the function correctly.
Secondly, it also prevents 'dedent' from being imported when using 'from
textwrap import *' (Yes, yes, I know this should never be done. Hence
why it is probably never noticed by anyone.)

New submission from fboule <fabien.bouleau at ses-engineering.com>:
This concerns a known bug in the frame_setlineno() function for Python
2.5.x and 2.6.x (maybe in earlier/later version too). It is not possible
to use this function when the address or line offset in lnotab are
greater than 127. The problem comes from the lnotab variable which is
typed char*, i.e. "signed char*" implicitly. Any value above 127 becomes
a negative number.
The fix is very simple (applied on the Python 2.6.1 version of the
source code):

Hi guys.. i found something strange on the behavior of OptionParser
If I have this sample code :
import sys
from optparse import OptionParser
if __name__ == '__main__':
parser = OptionParser()
parser.add_option("-p", "--p", help="The P of python", default=None)
parser.add_option("-y", "--y", help="The Y of python", default=None)
(options,args) = parser.parse_args(sys.argv)
print options
and i execute :
myFile.py -p -y
the options.p will be -y and options.y will be None
worst.. if my user say :
myFile.py -p -y 'thon'
options.p will be -y and options.y will be None...
In all case I think that, if i do
myFile.py -p -y
options -p and options -y must be None
and if i want to put -y in options.p i say something like
myFile.py -p "-y" so i can do after myFile.py -p "-y" -y "thon".

"If a name is declared global, then all references and assignments go
directly to the middle scope containing the module?s global names.
Otherwise, all variables found outside of the innermost scope are
read-only (an attempt to write to such a variable will simply create a
new local variable in the innermost scope, leaving the identically named
outer variable unchanged)." ___excerpt from <The Python

The above description is correct in Python 2.X.
Since 3.X introduced the "nonlocal" keyword, I think the above
description is obsolete, need to be upgraded.

For people who are following HOWTO guides verbatim, there are two types

1. ``print`` statements instead of functions.
2. Use of beloved but deprecated ``%`` format operator.

New submission from Lennart Regebro <regebro at gmail.com>:
The whatsnew/3.0.rst document claims
"It is not recommended to try to write source code that runs unchanged
under both Python 2.6 and 3.0; you?d have to use a very contorted coding
style, e.g. avoiding print statements, metaclasses, and much more. "
This is no longer true, since 2.6 now has much backwards compatibility,
including fopr print statements and unicode, so it's prefectly possible
and not at all contorted to support both any longer.
I'd recommend that the above statement is changed to "under both Python
2.5 and 3.0" or simply removed.

New submission from Christian Heimes <lists at cheimes.de>:
The new io library needs some serious profiling and optimization work.
I've already fixed a severe slowdown in _fileio.FileIO's read buffer
allocation algorithm (#4533).
More profiling tests have shown a speed problem in write() files opened
in text mode. For example three str.count() calls are taking up 20% of
the time. The str.count calls can be replaced with an optimized C
function that returns the count of (\r\n, \n, \r) in one pass instead of
three passes.

Subject: [New-bugs-announce] [issue4566] 2.6.1 breaks many applications that
embed Python on Windows
In-Reply-To: <1228577334.37.0.676469955994.issue4566@psf.upfronthosting.co.za>
Message-ID: <1228577334.37.0.676469955994.issue4566@psf.upfronthosting.co.za>
New submission from Craig Holmquist <craigholm at gmail.com>:
Applications on Windows that don't link to the MSVCR90.DLL via a
manifest are broken with Python 2.6.1. This includes apps that link
with the C library statically and apps that link with other versions of
it. These applications worked fine with Python 2.6.
To test this, I created a simple application that did nothing but call
Py_Main (compiled with VS2008). When that app links with the C library
statically, attempting to import the socket module gives this error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Python26\lib\socket.py", line 46, in <module>
import _socket
ImportError: DLL load failed: The specified module could not be found.
When that app links with the C library dynamically, it works properly.
In particular, this issue breaks mod_python. From the Apache error log:
[Sat Dec 06 00:49:21 2008] [error] make_obcallback: could not import
mod_python.apache.\n
Traceback (most recent call last):
File "C:\Python26\lib\site-packages\mod_python\apache.py", line 29, in
<module>
import cgi
File "C:\Python26\Lib\cgi.py", line 40, in <module>
import urllib
File "C:\Python26\Lib\urllib.py", line 26, in <module>
import socket
File "C:\Python26\lib\socket.py", line 46, in <module>
import _socket
ImportError: DLL load failed: A dynamic link library (DLL)
initialization routine failed.
I'm guessing this is a side-effect of the fix for #4120. Since modules
like _socket.pyd don't have manifests that tell Windows where to find
the side-by-side assembly to load, and the application loading
_socket.pyd doesn't have it in its manifest either, Windows has no clue
where to find MSVCR90.dll.
Something I discovered (by accident) is that, if there's an external
manifest in the same folder as the hosting application (ie,
testpy.exe.manifest) that points to the C runtime, it fixes the problem,
even if the host app links statically to the C runtime. I don't recall
off-hand whether these external manifests take precedence over the
internal ones, but in this case it seems to provide enough information
to Windows that it can resolve the dependency.

In the trunk (r67617) documentation for *optparse* callback example 6
doesn't handle negative number arguments, and fixing it is "left as an
exercise for the reader." Well, I'm a reader, and I've attached my stab
at it. Caveat: It relies in trying to coerce the argument into a
float... maybe there's a cleaner way to do it?
(This is my first patch, so I apologize if I've fouled it up in some
way, particularly in the headers of the patch format.)

New submission from jeff deifik <jeff at jeffunit.com>:
I have a program that needs to output binary data to stdout.
I don't want to convert it to a string.
for example something like
sys.stdout.write('0o377')
to write a byte with all the bits turned on.
When I try this, I get an error like:
sys.stdout.write(data)
File "/usr/local/lib/python3.0/io.py", line 1484, in write
s.__class__.__name__)
TypeError: can't write bytes to text stream
I know I can open a file in 'wb' mode and write to it, but what
I want to do is somehow switch the mode of stdout to 'wb' mode.
I read lots of python 3 documentation, as well as searched without
finding a way.

New submission from gumpy <gumpy2k7 at gmail.com>:
Currently io.IOBase.seek(offset[, whence]) uses magic numbers for the
second argument. Since this is essentially identical the C function
fseek I think adding the same "constants" that C uses (SEEK_SET=0,
SEEK_CUR=1, SEEK_END=2) may be worth considering.
These values could be added to the global scope in the io module:
f = io.open('foo', 'rb')
f.seek(0, io.SEEK_END)
If added to the io.IOBase class then I believe they'd be accessible
without importing io:
f = open('foo', 'rb')
f.seek(0, f.SEEK_END)

fnmatch/glob
In-Reply-To: <1228637877.49.0.438531462048.issue4573@psf.upfronthosting.co.za>
Message-ID: <1228637877.49.0.438531462048.issue4573@psf.upfronthosting.co.za>
New submission from Erick Tryzelaar <idadesub at users.sourceforge.net>:
As I mentioned on python-ideas, I my project needs to extend fnmatch to
support zsh-style globbing, where you can use brackets to designate
subexpressions. Say you had a directory structure like this:
foo/
foo.ext1
foo.ext2
bar/
foo.ext1
foo.ext2
The subexpressions will let you do patterns like this:
>>> glob.glob('foo/foo.{ext1,ext2}')
['foo/foo.ext1', 'foo/foo.ext2']
>>> glob.glob('foo/foo.ext{1,2}')
['foo/foo.ext1', 'foo/foo.ext2']
>>> glob.glob('{foo,bar}')
['bar', 'foo']
>>> glob.glob('{foo,bar}/foo*')
['bar/foo.ext1', 'bar/foo.ext2', 'foo/foo.ext1', 'foo/foo.ext2']
>>> glob.glob('{foo,bar}/foo.{ext*}')
['bar/foo.ext1', 'bar/foo.ext2', 'foo/foo.ext1', 'foo/foo.ext2']
>>> glob.glob('{f?o,b?r}/foo.{ext*}')
['bar/foo.ext1', 'bar/foo.ext2', 'foo/foo.ext1', 'foo/foo.ext2']
Would this be interesting to anyone else? It would unfortunately break
fnmatch since it currently treats {} as ordinary characters. It'd be
easy to work around that by adding a flag or using a different function
name though. Anyway, here's the patch against the head of py3k.

New submission from John Machin <sjmachin at users.sourceforge.net>:
Problem in the newline handling in io.py, class
IncrementalNewlineDecoder, method decode. It reads text files in 128-
byte chunks. Converting CR LF to \n requires special case handling
when '\r' is detected at the end of the decoded chunk in case
there's an LF at the start of the next chunk. It prepends b'\r' (only 1
byte) to the next chunk's raw bytes and decodes that. But \r in UTF-16
takes 2 bytes; we are now 1 byte out of kilter and various failures are
possible (including silently producing garbage output from a truncated
file with an odd number of bytes).
The attached script illustrates the problems.

test_cmath failure on x86

Message-ID: <1228653764.46.0.349797077595.issue4575@psf.upfronthosting.co.za>
New submission from Mark Dickinson <dickinsm at gmail.com>:
In issue 4506, Skip reported that test_cmath fails on Solaris 10/x86 for
3.0. If my guesses are correct, it probably fails on all x86 systems that
(a) use the x87 coprocessor for floating-point (as opposed to using SSE2,
for example), and (b) don't have isinf available.
Problem: Py_IS_INFINITY is applied to a floating-point value sitting in an
80-bit x87 register; that value is not infinity, but after moving it back
to memory (and hence rounding from 80-bit extended precision to 64-bit
double precision with its smaller exponent range) it becomes infinity.
Solution: Add a macro to pymath.h that forces rounding from extended
precision to double precision; apply this macro *before* calling
Py_IS_INFINITY. See attached patch for an example.
Problem: After applying the attached patch to the py3k branch, the cmath
module fails to build. On OS X 10.5, I get:
running build_ext

Solution: ???
Christian, as the architect of pymath.h, do you have any ideas what I'm
doing wrong? Or comments on the patch in general? What do I need to do
to make Py_force_to_memory visible to extension modules?

This is very strange behaviour. First, .read() succeeds, and .readline()
fails, but after writing and seeking, .read() also fails.
In python3, both read and readline fail, but with different exceptions:

In my opinion, all operations, in all python versions, should fail like
readline in the first example: IOError: [Errno 9] Bad file descriptor

array('i', [0, 1, 2, 3, 4, 5, 6, 7, 8, 9])

An additional problem is that `shape` is a pointer to an array of
integers, and we don't know how to reallocate it.

Subject: [New-bugs-announce] [issue4585] Build failure on OS X 10.5.5: make:
*** [sharedmods] Error 1

New submission from Mark Dickinson <dickinsm at gmail.com>:
There are two recent reports of build failures of Python 3.0 on OS X
10.5.5: see
http://mail.python.org/pipermail/python-list/2008-November/514159.html
and
http://mail.python.org/pipermail/python-3000/2008-December/015404.html
It seems likely that these are related. For both reports the build
eventually fails with something like:
gcc Python.framework/Versions/3.0/Python -o python.exe \
Modules/python.o \
-ldl
make: *** [sharedmods] Error 1
I can reproduce this in the py3k branch and release30-maint branch on my
Macbook by doing (at a Terminal prompt):
export LC_CTYPE="UTF-8"
./configure && make
I'll try to find time to look at this; any and all help welcomed!

On the page:

Note that the function "Py_InitModule" is used. From what I can tell,
this function no longer exists and regrettably I can't figure out how to
get "PyModule_Create" to work in its place.

New submission from Skip Montanaro <skip at pobox.com>:
Fixing issue4483 resulted in adding an extra header file check for
gdbm-based header files when the gdbm library was found. This caused
problems for Roumen Petrov. In considering the problems he encountered I
decided we probably need to provide users some more flexibility when
deciding which libraries and header files to use when building the dbm
module (or _dbm on 3.0). For example, the current hard-coded perform checks
in this order: ndbm, gdbm, BerkDB. What if the system has hdbm installed
but the builder wants to use the BerkDB compatibility API?
This ticket is to track the discussion and come up with a suitable system.

I want to make my own data of types bytes in order to write it out.
For example, I want to write out the bytes 0..9

foo = b''
for i in range (0,10):
foo += i
#sys.stdout.buffer.write(foo)
Here is the error:
Traceback (most recent call last):
File "./x.py", line 4, in <module>
foo += i
TypeError: can't concat bytes to int
I cannot find any function to convert the int i into something
that I can append to foo. I tried chr, which produced a string
typeerror. byte() was not defined. There must be a way to convert
an integral value to a bytes type.

In-Reply-To: <1228717270.54.0.0773896272442.issue4589@psf.upfronthosting.co.za>
Message-ID: <1228717270.54.0.0773896272442.issue4589@psf.upfronthosting.co.za>
New submission from Jeffrey Yasskin <jyasskin at gmail.com>:
When a context manager's __exit__() method returns an object whose
conversion to bool raises an exception, 'with' loses that exception. For
example:
>>> class CM(object):
... def __init__(self, exit_result):
... self.exit_result = exit_result
... def __enter__(self):
... return 3
... def __exit__(self, a, b, c):
... return self.exit_result()
...
>>> class TrueAsBool(object):
... def __nonzero__(self): return True
...
>>> class FalseAsBool(object):
... def __nonzero__(self): return False
...
>>> class FailAsBool(object):
... def __nonzero__(self):
... raise RuntimeError("Should see this but won't")
...
>>> with CM(TrueAsBool):
... raise AssertionError("Should NOT see this")
...
>>> with CM(FalseAsBool):
... raise AssertionError("Should see this")
...
Traceback (most recent call last):
File "<stdin>", line 2, in <module>
AssertionError: Should see this
>>> with CM(FailAsBool):
... raise AssertionError("Should see RuntimeException (oops)")
...
>>>
The problem is that WITH_CLEANUP only checks if PyObject_IsTrue(x)
returns non-zero, but that function returns <0 when the bool conversion
raises an exception.

I noticed that fix_long and fix_numliterals both strip trailing Ls from
numbers. That's redudant, one of them should be enough.
I attached a patch that removes the literal changing from the fix_long
fixer. Because I'm not sure if that may be the correct fixer to modify
I didn't commit it but created an issue for review.

New submission from Sjoerd Mullender <sjoerd at acm.org>:
On Fedora 8 and 10 using Python 2.5.1 and 2.5.2 (64 bit):
$ grep nfsnobody /etc/passwd
nfsnobody:x:4294967294:4294967294:Anonymous NFS
User:/var/lib/nfs:/sbin/nologin
So the UID of nfsnobody is 4294967294 (-2 if viewed as signed 32-bit int).
>>> import pwd, os
>>> print pwd.getpwnam('nfsnobody').pw_uid
4294967294
>>> os.chown('some file', pwd.getpwnam('nfsnobody').pw_uid,
pwd.getpwnam('nfsnobody').pw_gid)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OverflowError: signed integer is greater than maximum
The reason for this error is that os.chown uses the "i" format to
convert the second and third arguments. But the valued do not fit in a
32-bit signed integer. uid_t and gid_t are defined as unsigned
quantities on this system.
The bug does not occur on 32 bit Fedora since there the uid and gid of
nfsnobody are 65534.

The documentation for the apply() and apply_async() methods of a Pool
object might emphasize that these operations execute func(*args,**kwargs)
in only one of the pool workers and that func() is not being executed in
parallel on all workers. On first reading, I actually thought it might
be the latter (and had to do some experimentation to figure out what was
actually happening).

I downloaded the source to Python 3.0 onto my Nokia N810, an ARM-based
Linux machine. The native gcc is 3.4.4 (upgrading might be possible,
but would certainly be a pain). I was able to build only by switching
from -O3 to -O2; -O3 caused a compiler crash.
Now, this isn't really Python's fault; gcc really shouldn't be crashing.
However, it'd be nice if configure had a way to specify the
optimization level--I had to go in and edit the generated Makefile by
hand. Better yet would be if configure could recognize the platform and
set the -O level accordingly.

ob.__class__ = ob2
gives some confusing TypeError messages.
>>> c.__class__ = 1
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: __class__ must be set to new-style class, not 'int' object
Problem: 'new-style' is obsolete in 3.0. It is also too inclusive...
>>> c.__class__ = object
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: __class__ assignment: only for heap types
object *is* 'new-style'. I presume 'heap type' means 'class defined by
class statement'. If so, let us say so, since beginning programmers may
not know what a 'heap type' is. If the above is incorrect, then this
experienced programmer also does not know what it means in Python
context ;-).
Proposal: when someone tries to set __class__ to an inappropriate
object, give similar error message for instances and heap classes.
TypeError: __class__ must be set to a class defined by a class
statement, not 'xxx' [object].
where 'object', without the brackets, is added for non-classes, as it is
today.
>>> c.__class__ = object
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: __class__ assignment: only for heap types
C, the class of c, *is* a heap type. The different problem, the target
being an instance of heap class, should get a different message. 'Heap'
is still possibly confusing. Proposal:
TypeError: __class__ assignment: only for instances of classes defined
by class statements.

The attached patch is a possible way to fix this issue. It'd be great

Well, Python does have a way - the way you have been using.
However, as yet another way, you can set the OPT environment variable,
to define the optimization flags to be used (and other non-essential
compiler flags).

I'm opposed. Selecting such a thing by platform and compiler version
is too transient to be maintainable. It would be different if the
platform would have been around for 10 years, and had seen no compiler
change for 8 years, but in this case, this likely is fixed before the
next Python release is even made. Please report this to the system
vendor.

New submission from Terry J. Reedy <tjreedy at udel.edu>:
In 2.6, Ref Manual / Lexical Analysis / Indentation says
"First, tabs are replaced (from left to right) by one to eight spaces
such that the total number of characters up to and including the
replacement is a multiple of eight (this is intended to be the same rule
as used by Unix). The total number of spaces preceding the first
non-blank character then determines the line?s indentation. "
and Using Python / Command line / Misc options says
"-t
Issue a warning when a source file mixes tabs and spaces for
indentation in a way that makes it depend on the worth of a tab
expressed in spaces. Issue an error when the option is given twice (-tt)."
Inyeol Lee, on c.l.p., in response to a report of a TabError, says "-tt
option in python 2.x is now default in python 3.0.
Apparently it got slipped from any documentation, including what's
new."
In 3.0 docs, the -t option *was* removed from Using Python, but the
Indentation sentences quoted above remain unchanged, though obsolete. I
would guess that they should be replaced by something like
"When a source file mixes tabs and spaces for indentation in a way that
makes it depend on the worth of a tab expressed in spaces, a TabError is
raised."
Perhaps What's New should get a sentence too. "The former -tt startup
option to raise TabError on ambiguous mixtures of tabs and spaces for
indentation has been removed as an option and is now the standard behavior."

New submission from chris <followingthepath at gmail.com>:
http://docs.python.org/3.0/library/stdtypes.html#str.translate
mentions the following:
"You can use the maketrans() helper function in the string module to
create a translation table."
But maketrans is now a string method not just a function of the string
module. It even mentions that right above it that it is now a method of
string objects:
"A map for translate() is usually best created by str.maketrans()."
The page where this all appears in is:
http://docs.python.org/3.0/library/stdtypes.html
It may have just not been updated fully from an older release.
If I am mistaken and this is not a bug, I appologise.

POINTER(...) doesn't always result in NULL

Message-ID: <1228816020.28.0.155864486659.issue4606@psf.upfronthosting.co.za>
New submission from Robert Luce <luce at math.tu-berlin.de>:
Consider the library 'c_lib.so' consisting of a single function 'c_func'
int c_func ( double *arg0, double *arg1, double *arg2, double *arg3,
double *arg4, double *arg5, double *arg6) {
printf("Value of arg0 is %p\n", arg0);
printf("Value of arg1 is %p\n", arg1);
printf("Value of arg2 is %p\n", arg2);
printf("Value of arg3 is %p\n", arg3);
printf("Value of arg4 is %p\n", arg4);
printf("Value of arg5 is %p\n", arg5);
printf("Value of arg6 is %p\n", arg6);
return 0;
}
and the following snippet:
from ctypes import *
c_lib = CDLL('c_lib.so')
t = POINTER(c_double)
c_lib.c_func.argtypes = [t,t,t,t,t,t,t]
def call_c_func():
nptr = None
c_lib.c_func(nptr, nptr, nptr, nptr, nptr, nptr, nptr)
The output I get from call_c_func() with Python 2.6 and Python 2.5 on a
64 bit Linux box is (it probably won't happen on 32 bit systems):
Value of arg0 is (nil)
Value of arg1 is (nil)
Value of arg2 is (nil)
Value of arg3 is (nil)
Value of arg4 is (nil)
Value of arg5 is (nil)
Value of arg6 is 0xa00000000
The reason appears to be that in 'PointerType_from_param' (_ctypes.c)
Py_None is converted to a Python integer of value 0. Later, in
'ConvParam' (callproc.c), this integer ends up as a 4 byte integer type
on the argument stack for ffi. I don't know anything about ffi, but this
looks at least suspicious on any platform where sizeof(void*) is 8.
I propose to remove NULL pointer handling from the above from_param
function, since Py_None is properly handled by ConvParam itself. A patch
against the 2.6 maintenance branch is attached.

Following a discussion on reddit it seems that the unicode case

$ python3.0
Python 3.0rc1 (r30rc1:66499, Oct 10 2008, 02:33:36)

>>> x='?'
>>> print(x, x.upper())
? ?
This conversion is correct as defined in UnicodeData.txt however
http://unicode.org/Public/UNIDATA/SpecialCasing.txt defines a more
complete set of case conversions.
According to this file "?".upper() should be "SS". Presumably Python
simply isn't using this file to create it's mapping database.

In reference to Issue4592 (which includes a patch),
PyModule_Create()calls PyModule_New instead of PyImport_AddModule.
Because of this, calling PyModule_Create() won't work like Py_InitModule().
Is this correct, because the documentation is showing that
PyModule_Create() is all you need to use to create and add a module to
the system. However, this is not the case.

New submission from Albert Hopkins <marduk at python.net>:
Say I have module foo.py:
def a(x):
def b():
x
del x
If I run foo.py under Python 2.4.4 I get:
File "foo.py", line 4
del x
SyntaxError: can not delete variable 'x' referenced in nested
scope
Under Python 2.6 and Python 3.0 I get:
SyntaxError: can not delete variable 'x' referenced in nested
scope
The difference is under Python 2.4 I get a traceback with the lineno and
offending line, but I do not get a traceback in Pythons 2.6 and 3.0.
This also kinda relates to the 2to3 tool. See:

else:
k = x
if k in keys:

is also an exception target

Message-ID: <1228911523.24.0.570670634565.issue4617@psf.upfronthosting.co.za>
New submission from Amaury Forgeot d'Arc <amauryfa at gmail.com>:
This issue comes from issue4613. The following code raises a
SyntaxError("can not delete variable 'e' referenced in nested scope"):
def f():
e = None
def g():
e
try:
pass
except Exception as e:
pass # SyntaxError here???
The reason is because of
http://www.python.org/dev/peps/pep-3110/#semantic-changes, a "del e"
statement is inserted.
The above code is correct, and should work.
I suggest that the limitation: "can not delete variable referenced in
nested scope" could be removed.
After all, the "variable referenced" has no value before it is set,
accessing it raises either NameError("free variable referenced before
assignment in enclosing scope") or UnboundLocalError("local variable
referenced before assignment")
The Attached patch adds a DELETE_DEREF opcode, that removes the value of
a cell variable, and put it in a "before assignment" state.
Some compiler experts should review it. Few regressions are possible,
since the new opcode is emitted where a SyntaxError was previously
raised. The patch could also be applied to 2.7, even if it is less
critical there.
Tests are to come, but I'd like other's suggestions.

Argument is a Mutable Object

New submission from Robert Hunger <rhunger at gmx.ch>:
Reopening of issue 4181.
Evaluating default parameter values when the function definition is
executed is a design bug.
Even the documentation of this behaviour (see
http://docs.python.org/reference/compound_stmts.html#index-754) makes
this clear by stating: "This is generally not what was intended." It
then makes a suggestion for a workaround ("A way around this ..."). Only
bugs need workarounds.
An interface or behaviour should fulfil a users expectation for the
"normal" case, not for some "special" case. For a default parameter
value a user expects that whenever this function gets called a new
instance of a mutable object is created. This is much closer to the
current behaviour for non-mutable objects.
Usage cases for the current default behaviour are less common.

Each entry of a zip file, as read by the zipfile module, can be accessed
via a ZipInfo object. The filename attribute of ZipInfo is a string.
However, the read method of a ZipFile object expects a binary as
argument, or at least this is what I can deduct from the following behavior:
>>> import zipfile
>>> testzip = zipfile.ZipFile('test.zip')
>>> t1 = testzip.infolist()[0]
>>> t1.filename
't?st.xml'
>>> data = testzip.read(testzip.infolist()[0])

When I look at the folder .idlerc in windows explorer, I get an error
each time I click on it that access is denied, even though I am running

deleting the .idlerc folder. I have also tried manually unchecking the

Now, it's gone in Python 2.6.1, and it was never there for Python 3.0.
Which is a pain, because it's really hard to get "readlines" to install
just using config/make/install.
So, whoever is in charge of making that disk image should make it again.

New submission from Brett Cannon <brett at python.org>:
Passing in bytes to compile() works well for letting the parser handle
the decoding of a file when an encoding is specified, but it doesn't
take care of universal newlines::
>>> source = b'a = 1\r\nb = 2\r\n'
>>> compile(source, '<test>', 'exec')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<test>", line 1
a = 1

Consider the following program tmp.py:
import sys, getopt
print(getopt.getopt(sys.argv[1:], '', ['help']))
The program accept "--help" without a value:
python helloworld.py --help
But if someone invoke the program like:
python helloworld.py --help=
Python should raise an error.
"--help=" is not considered as no_argument in libc's getopt implementation (tested on Mac OS X
Leopard):
#include <getopt.h>
static struct option longopts[] = {
{ "help", no_argument, NULL, "h" },
};
#include <getopt.h>
static struct option longopts[] = {
{ "help", no_argument, NULL, 'h' },
};
int main(int argc, char **argv)
{
while (getopt_long(argc, argv, "h", longopts, NULL) != -1);
return 0;
}

New submission from Mark Summerfield <mark at qtrac.eu>:
IDLE's cursor blinks with Python 3.0 on Linux.
But it shouldn't (and doesn't for prior versions) because in my
.Xdefaults file I have the line:
*insertOffTime: 0
Now I have to manually edit idlelib/EditorWindow.py to stop the cursor
from blinking.
(I also have to do this on Windows because IDLE ignores the blink rate
set in the control panel.)
I am one of a minority of people who cannot work with blinking cursors.
I hope that at the least IDLE will get an option to switch it off.

I find that file.tell returns not the byte offset of the next byte, but
possibly the byte offset of the next block to be read. I find it always
to be a multiple of 1024. Following is a demo of the bug. where I read a
few lines into a text file, step back by the length of the last read
line, read again, and do not find the same data. What is returned is the
tail part of a line way down in the file. I woeked around by keeping
track of the file pointer, and seek worked fine. tell() is at fault.

New submission from Allan Crooks <amc1 at users.sourceforge.net>:
If cgitb.html tries to get the value of an attribute from an object, and
the getattr call causes an exception to be raised (other than an
AttributeError), then cgitb.html fails to work:
If you run the attached file in Python 2.5.2 or 2.6, you get the
following output:
----
A: the letter a
B:
Something went wrong - attempting to generate HTML stack trace.
Error generating HTML stack trace!
Traceback (most recent call last):
File "attrtest.py", line 21, in <module>
html_text = cgitb.html(sys.exc_info())
File "C:\python26\lib\cgitb.py", line 133, in html
vars = scanvars(reader, frame, locals)
File "C:\python26\lib\cgitb.py", line 84, in scanvars
value = getattr(parent, token, __UNDEF__)
File "attrtest.py", line 8, in __getattr__
return str(slf) # Intentional NameError
NameError: global name 'slf' is not defined
----
The problem is in the scanvars function - it offers no protection
against any unexpected exceptions that occur (that escape the getattr
call) - which can be a problem if it is the same problematic code that
caused cgitb.html to be called in the first place.
I think scanvars should catch any exceptions that come from the getattr
call and either mention that the attribute value could not be
determined, or simply omit the mention of the attribute at all.
If the line in the attached file is commented out, then the next line is
caught appropriately and formatted correctly (the offending code occurs
in the same block, but doesn't cause the same problem because it raises
an AttributeError).

It mentions that the script name is refactor.py, rather than 2to3.py (I

this is a python < 3k issue.

New submission from Thomas Heller <theller at ctypes.org>:
Distutils setup function accepts an 'options' named argument which
allows to pass options to subcommands in a dictionary (At the moment I
cannot find where this is documented).
When an empty dictionary is passed, distutils spits out a warning:
C:\sf\comtypes>py3 setup.py clean
c:\python30\lib\distutils\dist.py:259: UserWarning: Unknown distribution
option: 'options'
warnings.warn(msg)

...
I believe the bug is in all versions of Python; since it never has been
fixed (or even found) I'm not sure if it is worth fixing. However,
patch is attached.

The test fails raising the message:

AssertionError: could not roundtrip 'from . import sys': Expected node

Apparently the parser expects a NAME token and gets a DOT token.
This behaviour affects Python 2.5 and Python 2.6. Unchecked for Python 3.0.

Please look at the example code in the following Python 3.0
documentation/tutorial:
http://docs.python.org/3.0/tutorial/controlflow.html#break-and-continue-statements-and-else-clauses-on-loops
The line 4 has a little fix to be made:
from
... print(n, 'equals', x, '*', n//x)
to
... print(n, 'equals', x, '*', n/x)
You probably noticed that n//x was proposed to be fixed to n/x. Please
note that this is Python 3.0 code. It's a small fix so I hope you won't
mind to fix this.

I have installed python 3.0 on Ubuntu 8.10 yesterday and played around
with the new unicode features and had no problems with Japanese
characters(both in interactive and script mode). However, after
rebooting, IDLE will no longer let me input any Japanese characters.
(I have it set to UFT-8, if it makes any difference anymore)
The terminal works fine. It lets me input Japanese and runs commands
correctly.
So I used gedit and saved a simple print("Hello(in Japanese chars)"),
and run it with IDLE 3.0 but I get a blank line >>>.
(Can I also make sure that I'm opening IDLE correctly? This is how I do it:
1)Open Terminal
2)~$ Python.3.0
3)>>> input idlelib.idle
Thank You in advance.

I ran my typo.pl perl script that locates possible C/C++ typos.
I found four that looked valid.
Two of the typos were in the Python directory {pythonrun.c,
dynload_win.c}, two were in PC/bdist_wininst {install.c, extract.c}.
Python/dynload_win.c:
Win32 API FormatMessageW() expects the 6th parameter to be the count of
characters, NOT the count of bytes.
Python/pythonrun.c:
The source code contains "if (ferr != NULL || ferr != Py_None)". This
does not work as expected - if ferr == NULL, then the second part of
the if expression will succeed. Look at the code handling fout about 8
lines up to see the correct code.
PC/bdist_wininst/extract.c:
Win32 API CreateFileMapping returns NULL on error, not
INVALID_HANDLE_VALUE.
PC/bdist_wininst/install.c:
Win32 API CreateFileMapping returns NULL on error, not
INVALID_HANDLE_VALUE.

2./home/share/a.lnk which is symbolic link to the /home/share/temp/a
3./home/share/temp/test.py whose contents are

print sys.version
print os.uname()
print os.path.realpath("/home/share/temp/../a.lnk")
print os.path.abspath("/home/share/temp/../a.lnk")
and I ran the python script on two different machines,but the version
of python interpreters are the same,and both of them are 64 bits machine,
but the result of os.path.realpath is different,one is

New submission from Jake <jah.mailinglist at gmail.com>:
When installing python 2.6, I used:
./configure --prefix=/home/name/usr
Installation was fine and everything was installed to:
~/usr/lib/python2.6
But the .so files were installed to:
~/usr/lib/python
As ~/usr/lib/python was (no longer) declared in my PYTHONPATH, I ran
into import issues. The problem was due to a forgotten file:
~/.pydistutils.cfg
So this is clearly a user error, but I wonder if it is something which
should be avoided at the setup.py level.
When installing python, the installation locations are derived from the
results of ./configure. When setup.py is eventually called, the
installation locations can change. This seems undesirable. Would it be
better if setup.py instructed distutils to ignore any configuration file
so that the installation directories matched what was used by the rest
of 'make install'?

[From a question sent to the python-help list.]
In the Python 3 tutorial at:
http://docs.python.org/3.0/tutorial/datastructures.html#dictionaries
it says:
The keys() method of a dictionary object returns a list of all the keys
used in the dictionary, in arbitrary order if you want it sorted, just
apply the sort() method to the list of keys
But in What's New in Python 3.0 at:
http://docs.python.org/3.0/whatsnew/3.0.html
it says:
dict methods dict.keys(), dict.items() and dict.values() return ?views?
instead of lists. For example, this no longer works: k = d.keys();
k.sort(). Use k = sorted(d) instead
I expect that it's just a matter of updating the tutorial.

New submission from Nick Coghlan <ncoghlan at gmail.com>:
When writing the unit tests for running doctests from inside a zipfile,
I initially had "<anon>" as the name being passed to the
doctest.DocTestFinder.find method.
With that name, the line numbers coming back for all of the examples
were being incremented by 1 beyond what test_doctest expected (and hence
my tests were failing).
Changing the name to "anon" eliminated the errors. (Both "<anon" and
"anon>" also failed in the same fashion as "<anon>")
I suspect there may be a problem with __LINECACHE_FILENAME_RE when "<"
or ">" are embedded in the name used for the doctest execution.

task_done() issue

Message-ID: <1229273282.85.0.657676661464.issue4660@psf.upfronthosting.co.za>
New submission from Brian <brian at merrells.org>:
Despite carefully matching my get() and task_done() statements I would
often trigger "raise ValueError('task_done() called too many times')" in
my multiprocessing.JoinableQueue (multiprocessing/queues.py)
Looking over the code (and a lot of debug logging), it appears that the
issue arises from JoinableQueue.put() not being protected with a locking
mechanism. A preemption after the first line allows other processes to
resume without releasing the _unfinished_tasks semaphore.
The simplest solution seems to be allowing task_done() to block while
waiting to acquire the _unfinished_tasks semaphore.
Replacing:
if not self._unfinished_tasks.acquire(False):
raise ValueError('task_done() called too many times')
With simply:
self._unfinished_tasks.acquire()
This would however remove the error checking provided (given the many
far more subtler error that can be made, I might argue it is of limited
value). Alternately the JoinableQueue.put() method could be better
protected.

New submission from Adeodato Sim? <dato at net.com.org.es>:
Currently, email.parser/feedparser can only parse messages that come
as a string, or from a file opened in text mode.
Email messages, however, can contain 8bit characters in any encoding
other than the local one (yet still be valid e-mails, of course), so I
think a method is needed to have the parser be able to receive bytes.
At the moment, and as far as I can see, it's not possible to parse
some perfectly valid messages with python 3.0.
I don't think it's appropriate to ask that files be opened with the
proper encoding, and then for the parser to read them. First, it is
not possible to know what encoding that would be without parsing the
message. And second, a message could contain parts in different
encoding, and many mailboxes with random messages most certainly do.
Also, message objects will need a way to return a bytes repreentation,
for the reasons explained above, and particularly if one wants to
write back the message without modifying it.

Simply bumping TextIOWrapper._CHUNK_SIZE from 128 to 1024 yields some

New submission from Skip Montanaro <skip at pobox.com>:
I don't know if the Python source is supposed to be compilable with a C++
compiler or not, but I'm having trouble finding a C compiler on the
Solaris10/SPARC machines at work. I decided to give a C++ compiler a whirl:
/opt/gnu/bin/c++ -c -fno-strict-aliasing -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -I. -IInclude -I../Include -DPy_BUILD_CORE -o Parser/tokenizer.o ../Parser/tokenizer.c
../Parser/tokenizer.c: In function `char * PyTokenizer_RestoreEncoding(tok_state *, int, int *)':
../Parser/tokenizer.c:1614: ANSI C++ forbids implicit conversion from `void *' in assignment
Now this turns out to be a very old compiler:
% /opt/gnu/bin/c++ --version
2.95.3
Should Python be able to compile with this ancient GNU C++ compiler?
Thx,
Skip

Running pydoc [ pydoc <modulename> ] on a python module using Tkinter
displayed the window defined in the module - not what I was
expecting.. Running pydoc on
from os import remove
sFile='tmp.tmp'
remove(sFile)
will remove the file tmp.tmp, if it exists.
If this behaviour is intentional ( as it appears to be, see
imp.load_module ) & presumably integral to the operation of pydoc, then
it might be worth providing a warning on the web page (
http://docs.python.org/library/pydoc.html ) ??
Running a code with default arguments in an arbitrary directory could
potentially produce unwanted side effects, at the very least..

but calling the same swig command works fine. It's the same copy of
swig, but it seems to be distutils rather than swig that is throwing the
error. This is particularly relevant since I need to use -outdir to meet
the autotools "distcheck" requirement of successfully building from a
build-dir separate from the source dir: code generation tools like SWIG
blur such a distinction and so need to support output location flags
like -outdir.
I see this was also noticed some time ago:
http://osdir.com/ml/python.distutils.devel/2006-06/msg00009.html
but no useful reply was ever forthcoming ;( Maybe this time will be
luckier!

New submission from Andy Buckley <andy at insectnation.org>:
It would make package maintenance easier, as well as integration with
other build systems e.g. autotools (necessary for projects where not
everything is Python), if the distutils supported an uninstallation
command, e.g.
python setup.py uninstall
This would presumably require monitoring of which files were installed
where, and it's of course possible to do undesirable things, but exactly
the same counter-arguments exist for autotools, and there the uninstall
target is an important and useful feature for developers, once you know
how to behave in a way to make it safe.

New submission from Mihai Ibanescu <mihai.ibanescu at gmail.com>:
According to http://www.ietf.org/rfc/rfc2617.txt section 2, in basic
HTTP authentication the password can be any character (including newline).
urllib does the following:
_passwdprog = re.compile('^([^:]*):(.*)$')
That should be changed to:
_passwdprog = re.compile('^([^:]*):(.*)$', re.S)
otherwise newlines will not be caught by the second part of the regex,
and bad things are produced.
For a password with regular chars in it:
> python -c "import urllib; print urllib.splitpasswd('user:ab')"
('user', 'ab')
For a password with a newline:
> python -c "import urllib; print urllib.splitpasswd('user:a\nb')"
('user:a\nb', None)
The expected result should have been ('user', 'a\nb')

New submission from Somelauw <Somelauw at yahoo.com>:
I'm using python 3.0 final which was released on December the 3th.
I also have python 2.5 installed.
2 bugs in python3 IDLE which might be related (but don't have to)
1.
The Python3 IDLE sometimes suddenly closes.
It always happens when I'm using it for a while, then press the shift +
home or end key and then it just disappears and my unsaved work is lost.
It really completely exits without an error and I also don't see it on
the background.
I'm unable to reproduce the error. But it usually happens when I have
hold down shift and press the home key.
2.
When I have some code then scroll down the code, then hold down shift
and press up a few times, then press home the selected code completely
switches.
Instead some code above the cursor suddenly gets selected.
The reason I think both are related is because both involve shift + home
key.
Both of the bugs have never happened in the IDLE 1.2.1 which was part of
python 2.5.2
I think

New submission from Eric Eisner <ede at mit.edu>:
I discovered this when trying to splice a string containing unicode
codepoints higher than U+FFFF
all examples on 32-bit Ubuntu Linux
python 2.5.2 (for comparison):
sys.maxunicode # 1114111
len(unichr(66674)) # 1
len(u'\U00010472') # 1
len(u'??') # 2
unichr(66674)[0] # u'\U00010472'
python 3.0: (same behavior on ubuntu's rc1 package and my build(r67781)
from svn)
sys.maxunicode # 65535
len(chr(66674)) # 2
len('\U00010472') # 2
len('??') # 2
chr(66674)[0] # '\ud801'
I expect the nth element of a string to be the nth codepoint, regardless
of unicode settings. I don't know why the maxunicode is configured
differently (both compiled by ubuntu), but is this the expected behavior?
If this is actually the expected behavior, how can I configure a build
of python to use the larger maxunicode value?

New submission from Alex Roper <alexr at ugcs.caltech.edu>:
Hi,
I wrote a simple script (attached) to do some preprocessing of MediaWiki
XML dumps. When it has a 8 MB chunk ready to dump to disk, it forks, and
the child writes it out and (will) compress it, then exit. The main
thread continues as before. Note that the child thread never touches (or
executes code that has in scope) the shelve handle.
The attached script, as written, will work fine on dumps (I tested it on
enwikisource-20081112-pages-articles.xml available from
http://download.wikimedia.org/enwikisource/20081112/). If you uncomment
the fork on line 40 (and the exit() on line 46 of course) and run it, it
will die after writing out about 450 megabytes with the backtrace below.
This appears to happen deterministically at the same place 3 of the 3
times I ran it. Apologies for the size and complexity of the test, I
don't have time to reduce it further at the moment, and it looks like it
may be fairly involved. I can try to work out a reduced case later and
resubmit if no one wants to touch this as is;)
# I ran the script with:
bzcat enwikisource-20081112-pages-articles.xml.bz2 | ./convert.py
wikisource 8388608
# (after making a dir called wikisource)
Let me know if I can be of any assistance, and apologies if this is
somewhere documented and I missed it.
Using Python 2.6.1 as released from python.org.

It would be nice if Queue.Queue included a way to access the high-water

often useful when assessing application performance.
I am assuming this is cheap, i.e. O(1), to provide.

New submission from saa <p5thon at saaworld.com>:
In trying to use the mmap offset to allow me to work with a 12GB file, I
encountered the fact that the new offset parameter was a ssize_t, which
is only 32 bits on my platform (OS X). The mmap offset in C is defined
to be an off_t
(http://opengroup.org/onlinepubs/007908775/xsh/mmap.html), which is 64
bits on my platform. The attached patch attempts to fix the non-Windows
code to have an off_t offset parameter and allows my code to access all
12 GB of my file. As a warning, this is the first time I've even looked
at the Python source, and wouldn't even consider myself a Python coder;
I just use Python every few months. Review the patch carefully.

The 'b' format unit to PyArg_ParseTuple, PyArg_ParseTupleAndKeywords, and PyArg_Parse is described in the documentation (in Parsing arguments and
building values) as representing a signed char, but actually represents an
unsigned char.
Personally, I would say that this is a problem with the interpreter core,
but 'b' has been an unsigned char since 2000 and fixing it now would
probably break backwards compatibility of extensions.

The attached script, when edited to fill in valid LiveJournal
credentials (or InsaneJournal, if you change the URL and user list)
fails for me in a very odd way. It fetches the first two URLs quite
happily, and returns a 401 on the third after querying my password
manager about 6 times (always the third, no matter what the user list
is). Rebuilding the opener each time around the loop doesn't fix it.
Recreating the HTTPDigestAuthHandler (and then rebuilding the opener)
*does* fix it. Seems like any given instance of HTTPDigestAuthHandler
fails on the third hostname.
Python package version 2.5.1-5ubuntu5.2. Haven't tried it on newer versions.

All of a sudden, it shut off, closed and will no longer open. This

I uninstalled it and re-installed it to no avail. The command line works

Subject: [New-bugs-announce] [issue4686] Exceptions in ConfigParser don't
set .args
In-Reply-To: <1229545362.85.0.86911392572.issue4686@psf.upfronthosting.co.za>
Message-ID: <1229545362.85.0.86911392572.issue4686@psf.upfronthosting.co.za>
New submission from David M. Beazley <beazley at users.sourceforge.net>:
The ConfigParser module defines a variety of custom exceptions, many of
which take more than one argument (e.g., InterpolationError,
NoOptionError, etc.). However, none of these exceptions properly set
the .args attribute. For example, shouldn't NoOptionError be defined
as follows:
class NoOptionError(Error):
def __init__(self,option,section):
Error.__init__(self,"No option %r in section: %r" %
(option,section))
self.option = option
self.section = section
self.args = (option,section) #!! Added this line
This is kind of a minor point, but the missing args means that these
exceptions don't work properly with programs that need to do fancy kinds
of exception processing (i.e., catching errors and reraising them in a
different context or process).
I can't speak for Python 3.0, but it's my understanding that .args
should always be set to the exception arguments.
Don't ask how I came across this---it was the source of a really bizarre
bug in something I was playing around with.

New submission from Antoine Pitrou <pitrou at free.fr>:
With gc.DEBUG_STATS, each GC collection displays the elapsed time.
Unfortunately, this elapsed time includes the debug overhead itself,
most notable the calls to gc_list_size() which can be quite expensive
with lots of objects in the older generation. Consequently, collections
of generation 0 will incorrectly appear as very expensive, while in
non-debug mode they are very cheap.
Here is a patch to get a more useful output, by not including the time
taken in gc_list_size().

Split out from #4074, here is a standalone patch which disables GC
tracking for simple tuples (tuples made of atomic objects or immutable
containers, possibly nested). The performance improvement can be
evaluated using tuple_gc_hell.py from #4074.
The patch also adds a function named is_tracked() to the gc module.

closed sockets when use_poll=True
In-Reply-To: <1229560322.27.0.660252722227.issue4690@psf.upfronthosting.co.za>
Message-ID: <1229560322.27.0.660252722227.issue4690@psf.upfronthosting.co.za>
New submission from Forest Wilkinson <forest at users.sourceforge.net>:
With use_poll=True on linux, asyncore calls handle_write() after the
socket has been closed.
More specifically, it looks like asyncore dispatches handle_read() and
handle_close() events between the writable() test and the corresponding
handle_write() call. If handle_close() calls close(), as asyncore's
default implementation does, the subsequent handle_write() will fail and
generate an EBADF (bad file descriptor) exception. If handle_error()
also calls close(), as asyncore's default implementation does, this will
mean close() gets called twice on the same socket.
I am attaching example code which demonstrates the problem on Linux
2.6.24 using python 2.5.2, 2.5.3rc1, and 2.6. In one window, run
pollwritefail.py. In another window, establish a TCP connection to port
12345 and immediately close it without reading or writing. This can be
done from within the python interactive interpreter like this:
import socket
s=socket.socket( socket.AF_INET, socket.SOCK_STREAM); s.connect(
('localhost', 12345)); s.close()
The output from pollwritefail.py will look like this:
writable() - asyncore asked if we have data to write
handle_read() - asyncore asked us to read
handle_close() - asyncore said the remote host closed connection
close() - we are closing our end of the connection
handle_write() - asyncore asked us to write
handle_error() - asyncore exception: (9, 'Bad file descriptor')
close() - we are closing our end of the connection
IMHO, two things need fixing here:
1. When writable() returns True, the next handler asyncore calls should
be handle_write(). Calling other handlers in between risks invalidating
the writable() return value.
2. After close(), asyncore should not call handle_write(), even if
writable() would return true.

I made changes to my code and hit F5 to run it through IDLE. The code
appeared to run without any errors, but when I closed everything out and
ran it again it turned out to be full of errors.
I am able to replicate this problem with my code and have seen others
have the same problem, but its unclear when and what causes the caching
to take place. I created a test file that only contained "print hello".
I ran this, made changes and then ran it again. The changes were
reflected, but after testing my code, it still cached.
Attached is a simple python file I used to test everything out. Run the
test, then comment out the Struct class and run it again. No errors
should appear, but if you close the code, reopen it and then run it
again it will error.

In the main python Makefile.pre.in, the frameworkinstallextras target,
only used on OS X, has a bogus "Make" command instead of "$(MAKE)" as in
other targets. Traditionally and by default, the OS X root file system is
case-insensitive, in which case "Make" coincidentally does invoke
/usr/bin/make. However, with OS X installed on a case-sensitive fs, the
command fails. One-liner patch attached.

I am not sure, if this is intentional. But if you look at Python 3k and
3.1 installation.
changing mode of /usr/local/bin/pydoc to 755
changing mode of /usr/local/bin/idle to 755
changing mode of /usr/local/bin/2to3 to 755
changing mode of /usr/local/bin/smtpd.py to 755
running install_egg_info
* Note: not installed as 'python'.
* Use 'make fullinstall' to install as 'python'.
* However, 'make fullinstall' is discouraged,
* as it will clobber your Python 2.x installation.
ors at goofy:~/python/py3k$
pydoc, idle, 2to3 and smtp.py by default are Py3k's.
Where as python is Py2.x's.
Do you see the difference when one wants to try out python prompt.
- If he types python in the console, he would be greeted by 2.x
- If he types idle, he would be greeted by 3k.
pydoc may cause similar confusion too.
2to3 is okay because it is to be used by 3k,
Not sure about smtp.py
Do you agree this as an issue and if so, how do we address it?
- label idle as idle3.0 and pydoc as pydoc3.0 and make it default with
make fullinstall ?

Subject: [New-bugs-announce] [issue4701] range objects becomes hashable
after attribute access

New submission from Hagen F?rstenau <hfuerstenau at gmx.net>:
As reported by Dmitry Vasiliev on python-dev, a range object suddenly
becomes hash()able after an attribute access, e.g. by dir().
If I understand correctly, then the reason is that PyRange_Type doesn't
set tp_hash and PyType_Ready is not normally called on the type, but
only e.g. in PyObject_GenericGetAttr.
I don't see any use for range objects being hashable, as they don't even
have meaningful equality defined on them. So I'd recommend making them
unhashable. The attached patch does this and adds a test.

New submission from Philip Jenvey <pjenvey at users.sourceforge.net>:
Python 2.6's new msvc9compiler misbehaves when it can't find a compiler
(actually a utility of the missing compiler) in its query_vcvarsall() --
it raises an IOError instead of a typical distutils error
build tools expect a consistent set of potential exceptions from the
compiler suites, such as CCompilerError, DistutilsExecError,
DistutilsPlatformError, etc. Distributions like simplejson, Genshi, etc.
look for these errors when compiling their optional C extension speedups
as an indication that there's no compiler, and to fallback to their pure
python counterparts
An IOError in this case just doesn't make sense
This patch changes them to DistutilsExecErrors. Maybe it should be
DistutilsPlatformError -- whatever, just not IOError
I think this should be included in 2.6.2

pybench needs to be updated for Python 3.0, in particular to remove use of
cmp. Here's a patch, against the py3k branch.
Questions (mainly for Marc-Andr? Lemburg):
1. Should the version number be bumped for *all* tests, or just for those
that have changed? Assuming all tests.
2. Presumably these changes should appear in 3.0.1, and should be
backported to 2.x. Backport this to 2.6.2? Or just 2.7?
3. Should I update the sample output in the README file? I was going to
just change the PYBENCH 2.0 line to PYBENCH 3.0, but that seems a little
bit bogus without updating the rest.

New submission from STINNER Victor <victor.stinner at haypocalc.com>:
I like and I need an "unbuffered" standard output which was provided
by -u command line option (or PYTHONUNBUFFERED environment variable).
Current status of -u option in Python3: the option exists and change
the buffer size (disable buffering) of the stdin, stdout and stderr
file descriptors.
The problem is in initstdio() which creates files with buffering=-1
(default buffer) instead of buffering=0 (no buffering) or buffering=1
(line buffer). But open() enable line buffering of TextIOWrapper is
buffering=-1 and the raw file is a tty.
Example with py3k trunk:
------------
$ ./python
>>> import sys; sys.stdout.line_buffering
True
$ ./python |cat
>>> import sys; sys.stdout.line_buffering
False
------------
I would like line buffering when stdout is redirected to a pipe and -u
option is used. initstdio() have to be changed to choose buffering
option. So it's something like:

But "if (1)" have to be replaced "if -u option is used" :-) See

I was trying to install Twisted on my son's OLPC. Twisted comes with a
handful of C extensions which are all optional and most of which are not
expected to compile on this platform anyway (they are platform-specific
for Mac or Windows). If my son's OLPC had a C compiler installed, then
it would attempt to build those modules, fail, and proceed to install
Twisted. However, since it doesn't have a C compiler, then instead it
stops with an error.
It would be nice if Twisted could tell distutils to try to build a
module, and report whether the build succeeded, but don't stop the
entire setup().

New submission from Christian Taylor <dingo at chello.at>:
I've been playing around with the newly released Python 3.0, and I'm a
bit confused about the built-in round()-function. To sum it up in a
single example:
Python 3.0 (r30:67503, Dec 7 2008, 04:54:04)
[GCC 4.3.2] on linux2
>>> round(25, -1)
30.0
I had expected the result to be the integer 20, because:
1. The documentation on built-in functions says: "values are rounded to
the closest multiple of 10 to the power minus n; if two multiples are
equally close, rounding is done toward the even choice"
2. Both help(round) and the documentation on built-in functions claim
that, if two arguments are given, the return value will be of the same
type as the first argument.
Is this unintended behaviour, or am I missing something?

os.pipe should return inheritable descriptors on Windows.
Patch below, test attached. New pipe() returns descriptors, which
cannot be inherited. However, their permissions are set correctly, so
msvcrt.get_osfhandle and msvcrt.open_osfhandle can be used to obtain an
inheritable handle.
Docs should contain a note to the effect. 'On Windows, use
msvcrt.get_osfhandle to obtain a handle to the descriptor which can be
inherited. In a subprocess, use msvcrt.open_osfhandle to obtain a new
corresponding descriptor.'

New submission from Cournapeau David <david at ar.media.kyoto-u.ac.jp>:
I believe the current pyport.h for windows x64 has some problems. It
does not work for compilers which are not MS ones, because building
against the official binary (python 2.6) relies on features which are
not enabled unless MS_WIN64 is defined, and the later is not defined if
an extension is not built with MS compiler.
As a simple example:
#include <Python.h>
int main()
{
printf("sizeof(Py_intptr_t) = %d\n", sizeof(Py_intptr_t));
return 0;
}
If you build this with MS compiler, you get the expected
sizeof(Py_intptr_t) = 8, but with gcc, you get 4. Now, if I build the
test like:
gcc -I C:\Python26\include -DMS_WIN64 main.c
Then I got 8 as well.
I believe the attached patch should fix the problem (I have not tested
it, since building python on amd64).

New submission from Kuba Wieczorek <faw217 at gmail.com>:
This behaviour has been known of course for quite long time. I suppose
this is not intentional so I've played a bit with this and I hope you'll
consider some little change.
Currently, if a ZIP archive contains some subdirectories then
zipfile.ZipFile.extract()/extractall() will create files instead of
directories in the target location. This of course will lead some
scripts to crash (unless any work-around has been done) because files
from the subdirectories couldn't be created.
Attached is a patch against current 2.7 tree. Applied, will make
extractall() extract properly all the contents of the archive with
proper tree structure. If a directory name is passed to the extract(),
it will only create the directory itself without the contents (I guess
it is obvious).

New submission from Scott Dial <scott at scottdial.com>:
There is a problem with the table contents with respect to literals that
cannot be word-wrapped. I see this issue here:
http://docs.python.org/dev/2.6/library/multiprocessing.html
The line in the table of contents that reads "The multiprocessing.dummy
module" is broken in that the literal "multiprocessing.sharedctypes"
overflows into the right-hand side. It also ends up underneath the
contents on the right, which makes it extra hard to know what that entry
was about.
This instance may be browser specific, but I think it brings up a more
general question of what should be done with such long literals and how
overflow should be handled. And perhaps even whether it is wise to have
set the width of that div to such a narrow and specific value (230px).
I've attached a screenshot from Firefox 2.0.0.20/Win32 in case it is not
as reproducible as I would expect.

New submission from Christoph Zwerschke <cito at online.de>:
If you install sgmlop (downloadable from
http://effbot.org/downloads/#sgmlop) under Python 2.x, then this can
break xmlrpclib.
You can reproduce this problem as follows (I have tested with Py 2.4,
2.5 and 2.6):
------------
data = """<?xml version="1.0" encoding="UTF-8"?>
<methodCall><methodName>f</methodName><params>
<param><value>käse</value></param>
</params></methodCall>"""
import xmlrpclib
assert xmlrpclib.FastParser is None
print xmlrpclib.SgmlopParser and 'with' or 'without', 'sgmlop'
assert xmlrpclib.loads(data) == ((u'k\xe4se',), 'f')
------------
If sgmlop is installed, this gives a UnicodeDecodeError, otherwise
everything works well.
This happens because xmlrpclib prefers using sgmlop over
lib.parsers.expat, but fails to handle numeric character entities
properly with this parser.
Find attached a patch that fixes this problem.
I also wonder whether lib.parsers.expat shouldn't be preferred over
sgmlop, since the latter is somewhat outdated, and installing external
libraries should not cause crashes or wrong behavior of standard lib
modules (see also Issue1772916 for a similar problem).

New submission from Antoine Pitrou <pitrou at free.fr>:
This patch prints opcode statistics at the end of a pybench run if
DYNAMIC_EXECUTION_PROFILE has been enabled when compiling the interpreter.
Is it ok? Is it better to add it to the Benchmark class?

Subject: [New-bugs-announce] [issue4715] optimize bytecode for conditional
branches
In-Reply-To: <1229900285.73.0.345956521758.issue4715@psf.upfronthosting.co.za>
Message-ID: <1229900285.73.0.345956521758.issue4715@psf.upfronthosting.co.za>
New submission from Antoine Pitrou <pitrou at free.fr>:
This patch optimizes the bytecode for conditional branches.
For example, the list comprehension "[x for x in l if not x]" produced
the following bytecode:
1 0 BUILD_LIST 0
3 LOAD_FAST 0 (.0)
>> 6 FOR_ITER 23 (to 32)
9 STORE_FAST 1 (x)
12 LOAD_FAST 1 (x)
15 JUMP_IF_TRUE 10 (to 28)
18 POP_TOP
19 LOAD_FAST 1 (x)
22 LIST_APPEND 2
25 JUMP_ABSOLUTE 6
>> 28 POP_TOP
29 JUMP_ABSOLUTE 6
>> 32 RETURN_VALUE
but after the patch it produces the following bytecode:
1 0 BUILD_LIST 0
3 LOAD_FAST 0 (.0)
>> 6 FOR_ITER 18 (to 27)
9 STORE_FAST 1 (x)
12 LOAD_FAST 1 (x)
15 POP_JUMP_IF_TRUE 6
18 LOAD_FAST 1 (x)
21 LIST_APPEND 2
24 JUMP_ABSOLUTE 6
>> 27 RETURN_VALUE
Notice that not only the code is shorter, but the conditional jump
(POP_JUMP_IF_TRUE) jumps right to the start of the loop instead of going
through the JUMP_ABSOLUTE at the end. "continue" statements are helped
similarly.
Furthermore, the old jump opcodes (JUMP_IF_FALSE, JUMP_IF_TRUE) could
profitably be replaced by two new opcodes:
- one which jumps if true and pops otherwise
- one which jumps if false and pops otherwise

New submission from Fabio Zadrozny <fabioz at users.sourceforge.net>:
In Python 3.0, the interpreter will not shutdown properly after setting
a tracing function and something goes into stdout.
The code attached shows the problem in action: just execute it and
notice how the interpreter will be kept running after the code has been
executed.
There are some more things that need to be considered:
- If the print('here') is not called, it will shutdown
- If BOTH the print('here') and the sys.settrace(None) is not called, it
will NOT shutdown
Note: I've marked the bug as crash because it's halting, but maybe there
could be a better alternative for it...

In 2to3, execfile(file, globals, locals) is translated to
exec(open(file).read(), globals, locals)
But that's not correct, as the actual file from the executed code gets
wrong with that.
The correct thing would be:
exec(compile(open(file).read(), file, 'exec'), globals, locals)
So that the name of the file remains correct in the module that's being run.

New submission from Dmitry Vasiliev <dima at hlabs.spb.ru>:
It seems the wsgiref package was copied from Python 2.* without any
modifications. There are already 3 issues about that but they only
describe a part of the problem so I decided to start a new one. The
issues was:
http://bugs.python.org/issue3348
http://bugs.python.org/issue3795
http://bugs.python.org/issue4522
The attached patch fix the problem with the following changes:
- Fixed headers handling in wsgiref/simple_server.py;
- Fixed encoding problems. Now WSGI applications must return iterable
with bytes but start_response() allow status and headers as bytes and as
strings. "wsgi.input" file-like now use BytesIO instead of StringIO;
- Fixed tests;
- Updated documentation examples;

New submission from George <ge1 at mail.gr>:
I have Python 2.6.1 in Windows Vista. It happened in Python 2.6 and I
hoped it would be fixed. I don't know what happenes in other versions.
When I open a file containing a python program(".py"/".pyw" and even
one compiled with py2exe) made by using the PythonWX GUI programming
libraries it crashes immediately after the mouse hovers over the window
created by the program(spesifically in the area inside it). It happenes
both when the program is a ".py" file and a ".pyw" file or one compiled
with py2exe. I get a message that the program stopped working.
Shouldn'nt I get a message about wrong code? It doesn't crash in the
Python Shell, but it has happened ,too, a few times.
Do I do something wrong?
Is there something I should know?
The programs I use are not made by me(I can't yet make mine), but they
are examples downloaded or copy-pasted. Here is one:
import wx
app = wx.PySimpleApp()
frame = wx.Frame(None,-1,"Hello World")
frame.Show(True)
app.MainLoop()
Please tell me what is wrong or what I should do.

1. Create registry key (let's assume it's located in
HKEY_CURRENT_USER\TestKey);
2. Walk to it in "regedit";
3. Right-click on "(Default)" and select "Modify binary data";
4. Leave everything blank and press "OK";
5. Go to Python and execute this:
>>> import _winreg
>>> _winreg.QueryValue(_winreg.HKEY_CURRENT_USER, 'TestKey')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
SystemError: ..\Objects\stringobject.c:4271: bad argument to internal
function
== What is the expected output? What do you see instead?
I expect either returning "''" or some ValueError indicating that source
string is malformed.
== What version of the product are you using? On what operating system?
1. Windows XP Professional SP2 English;
2. Tested on Python 2.5.2;
3. Tested on Python 2.6.1;
4. Tested on Stackless Python 2.5.2.
== Please provide any additional information below.
And yes, I know that this function is lame and everybody using it also
is lame, but it's not really a reason to include buggy functions, right?

Probably the problem is only in windows, however i would like You to know.
I verified the same behaviour in (WindowsXP, spanish, SP3) using Python
2.5.2 and also in 2.6.1 (installers from Python.org).
In my case i have directory names, beginning with year/month numbers.
Aparrently python is confusing something, so os.path.basename is not
working:
dd = 'C:\downloads\hacking\0812logcompress'
>>> os.path.basename(dd)
'hacking\x00812logcompress'

New submission from rocky bernstein <rocky at gnu.org>:
When listing a traceback or showing stack frames or implementing a
debugger (or a tool which wants to track the exact location of the
source code), how is one supposed to detect a file located inside an egg
or some other archive mechanism?
There are a number of issues, I think. First, I think some sort of
consistent naming convention would be helpful.
Here's an example of the current situation. I have a file called
tracer.py inside egg
/usr/lib/python2.5/site-packages/tracer-0.1.0-py2.5.egg/tracer.py
and I get an exception inside of that. The traceback shows this:
File "build/bdist.linux-i686/egg/tracer.py", line 216, in size
The file information comes from frame.f_code.co_filename and its
relation to a file is a bit nebulous since there is no file either in
the filesystem with that path suffix nor a file in an with that name.
(It's possible there was a file with that suffix at one time during the
build of the egg.)
So possibly this is a bug.
Via the __loader__ key in the tracer module's __dict__ hash (a
zipimporter object) there is a _files hash which has a key "tracer.py"
with value
"/usr/lib/python2.5/site-packages/tracer-0.1.0-py2.5.egg/tracer.py".
This seems to correspond to a file tracer.py in zip file:
/usr/lib/python2.5/site-packages/tracer-0.1.0-py2.5.egg
Glomming the two parts together as one entity or one name is a bit weird
and means that things that work on files will have do some parsing to
figure out that this there is a member inside an archive (and egg here).
PEP 302 has lots of interesting things in it such as a way to get the
file source text, but it doesn't specify uniform file *names* of either
the surrounding package/archive or the member inside that.
So possibly this is an omission or something that should be added.
Finally looking at linecache.py, the function update_cache() has a
routine to do some sort of filename resolution consulting loaders using
the API of PEP 302. Possibly the name resolution part (without reading
file data) might be made callable by itself so that it returns a
package/archive name and a package/archive member name.

My text editor places a comment block at the top of each source file with
a block of information about the author, the project, license, etc. One
(rather pointless) line of this block looks like
# FILE: "somefile.py"
The re in `_find_lineno()` misinterprets this line as the beginning of the
docstring. I believe the attached patch maintains the spirit of the re,
while avoiding this false positive.

According to both of these bugs:
http://bugs.python.org/issue1398
http://bugs.python.org/issue4331
pickle can't pickle functools.partial objects. It looks the underlying
reason is that objects that pickle can't handle objects with __new__ and
keyword only arguments. To support this, would this require a new pickle
protocol and a __getnewfullargs__ that returns a tuple and dict?

New submission from Cournapeau David <david at ar.media.kyoto-u.ac.jp>:
I had some problems with python and universal builds related to the
WORDS_BIGENDIAN macro. Because universal builds are built in one pass
(one configure), the AC_C_ENDIAN cannot be used reliably. Example:
int main()
{
#ifdef WORDS_BIGENDIAN
printf("Big endian macro defined\n");
#else
printf("No big endian macro defined\n");
#endif
return 0;
}
If I build this against python 2.5, it prints no big endian macro (I
have an intel CPU), as expected. But with python 2.6.0 (official binary
from python.org), I get Big endian macro defined.

New submission from Senthil <orsenthil at gmail.com>:
This is a new change in the documentation.
Tutorial -> More Control Flow Tools -> pass Statements
There is a new section which says:
"However, as pass is silently ignored, a better choice may be to raise a
NotImplementedError exception:"""
While what the section says is correct, but its placement in the
documentation is inappropriate. The tutorial has not yet introduced the
reader to function and Exceptions, and this portion has squeezed its way
in between.
I feel, this needs to be rearranged. Georg, what is your thought?

Subject: [New-bugs-announce] [issue4730] cPickle corrupts high-unicode
strings
In-Reply-To: <1230035446.04.0.56766649246.issue4730@psf.upfronthosting.co.za>
Message-ID: <1230035446.04.0.56766649246.issue4730@psf.upfronthosting.co.za>
New submission from Nathaniel Smith <njs at pobox.com>:
cPickle.dump by default does not properly encode unicode characters
outside the BMP -- it throws away the high bits:
>>> cPickle.loads(cPickle.dumps(u"\U00012345"))
u'\u2345'
The problem is in dump, not load:
>>> pickle.dumps(u"\U00012345") # works
'V\\U00012345\np0\n.'
>>> cPickle.dumps(u"\U00012345") # no!
'V\\u2345\n.'
It does work correctly when using a more modern pickling protocol:
>>> cPickle.loads(cPickle.dumps(u"\U00012345", 1))
u'\U00012345'
>>> cPickle.loads(cPickle.dumps(u"\U00012345", 2))
u'\U00012345'
But this is not much comfort for users whose data has been corrupted
because they went with the defaults. (Fortunately in my application I
knew that all my characters were in the supplementary plane, so I could
repair the data after the fact, but...)
Above tests are with 2.5.2, but from checking the source, the bug is
obviously still present in 2.6.1:
cPickle.c:modified_EncodeRawUnicodeEscape has no code to handle 32-bit
unicode values.
OTOH, it does look like someone noticed the problem and fixed it for
3.0; _pickle.c:raw_unicode_escape handles such characters fine. Guess
they just forgot to backport the fixes... but the code is there, and can
probably just be copy-pasted back to 2.6.

I was thrown by the "Failed to find the necessary bits to build these
modules" message at the end of newer Python builds, and thought that
this indicated that the Python executable itself was not built.
That's arguably stupidity on my part, but I wonder if others will not
trip on this, too.
Would it be possible to change this wording slightly, to something like
Python built, but failed to find the necessary bits to build these
modules
?

segfault on RHEL

New submission from Andrew Gillis <fbsdboy at gmail.com>:
Allocating large numbers of strings objects has been causing Python to
segfault on RHEL. Originally detected when sending large data
structures over XMLRPC, but also happens when appending large numbers of
small strings to a list and calling join in the list.
-- Crash is always a segmentation fault when accessing the free list to
allocate a python object (obmalloc.c) or an invalid pointer when
accessing a string object during a join operation (stringobject.c)
-- Happens on RHEL with latest updates and no modified RPMs.
-- Also happens with Python built from source on RHEL machine.
-- Crash happens on RHEL machines running on different hardware.
-- Reproducible with Python 2.4, 2.5, 2.6 and RHEL 5.1 and 5.2.
-- Problem not seed on FreeBSD 6.2 or 7.0.
Attached to the bug report is a script that is capable of recreating the
problem on various RHEL and Python versions. If running three instances
of the script, usually one of them will segfault within 30 minutes.
Below is a backtrace from the crash. This is in a call to join(),
concatenating a very long sequence of strings. While iterating over the
sequence of string objects to get the memory needed, one of the string
objects appears to be located in invalid memory, resulting in segfault.

New submission from Daniel Diniz <ajaksu at gmail.com>:
This patch adds a version of urlopen that uses available encoding
information to return strings instead of bytes.
The main goal is to provide a shortcut for users that don't want to
handle the decoding in the easy cases[1]. One added benefit it that the
failures of such a function would be make it clear why 2.x style "str is
either bytes or text" is flawed for network IO.
Currently, charset detection simply uses addinfourl.get_charset(), but
optionally checking for HTTP headers might be more robust.

urllib to have an option to automatically decode and return a string
instead of bytes.

New submission from ebfe <knabberknusperhaus at yahoo.de>:
My application needs to pack and unpack workunits all day long and does
this using multiple threading.Threads. I've noticed that the zlib module
seems to use only one thread at a time when using [de]compressobj(). As
the comment in the sourcefile zlibmodule.c already says the module uses
a global lock to protect different threads from accessing the object.
While the c-functions release the GIL while waiting for the global lock,
only one thread at a time can use zlib.
My app ends up using only one CPU to compress/decompress it's workunits...
The patch (svn diff to ) attached here fixes this problem by extending
the compressobj-structure by an additional member to create
object-specific locks and removes the global lock. The lock protects
each compressobj individually and allows multiple python threads to use
zlib in parallel, utilizing all available CPUs.

When I first came across decorators (about a year ago?), they confused

One of the things that I tried was help('@') but that didn't work
either. This patch is to make that work, and also a lot of other
google-proof syntax constructs.

I've tried to do it with as few changes/duplications as possible, but my
style is quite different from the rest of the module. I hereby donate my
code to whoever wants to commit it. Do what you want with it, and clean
it up however you want. I'm doing it for the n00bs.
The patch is against pydoc.py from python 2.5.2-0ubuntu1. If you want me
to create a patch against another version of python, send me an email.
Otherwise, apply it by hand: I've tried to make as few changes as
possible, so it shouldn't be too tricky.
Notes on other versions of Python
=================================
Python 3000 (and maybe 2.6? I've not checked) has the note:
# CAUTION: if you change one of these dictionaries, be sure to adapt the
# list of needed labels in
Doc/tools/sphinxext/pyspecific.py and
# regenerate the pydoc_topics.py file by running
# make pydoc-topics
# in Doc/ and copying the output file into the Lib/ directory.
but all I'm doing is adding aliases, so you shouldn't need to rebuild
the docs just to get help() working. Note that I've not actually tested
this though.
To test, I did:
python -c 'import pydoc ; help(":=")' | grep 'no Python documentation
found for .*'
which should print:
no Python documentation found for ':='
and:
python -c 'import pydoc ; [help(k) for k in pydoc.help.symbols]' | grep
-c 'no Python documentation found for .*'
which should print nothing.

New submission from John Machin <sjmachin at users.sourceforge.net>:
In a package, "import local1, local2" is not fixed. Here's some real
live 2to3 output showing the problem and the workaround:
import ExcelFormulaParser, ExcelFormulaLexer
-import ExcelFormulaParser
-import ExcelFormulaLexer
+from . import ExcelFormulaParser
+from . import ExcelFormulaLexer
import sys, struct
-from antlr import ANTLRException
+from .antlr import ANTLRException
As a solution that covers cases like "import sys, local1, local2" is
possibly difficult, I suggest putting out a warning that a manual fix
(one import per line) may be required. I've put this kludge in my copy
of fix_import.py:
def probably_a_local_import(imp_name, file_path):
+ if "," in imp_name:
+ print("*** Can't handle import %r in %s" % (imp_name, file_path))
# Must be stripped because the right space is included by the parser
imp_name = imp_name.split('.', 1)[0].strip()
base_path = dirname(file_path)
base_path = join(base_path, imp_name)
[Aside: "right space"? Possibly should be "left space"]
and it produces:
*** Can't handle import ' ExcelFormulaParser, ExcelFormulaLexer' in
\2to3\xlwt\py3\xlwt\ExcelFormula.py
*** Can't handle import ' sys, struct' in
\2to3\xlwt\py3\xlwt\ExcelFormula.py

New submission from David M. Beazley <beazley at users.sourceforge.net>:
The documentation for asynchat needs to be more precise in its use of
strings vs. bytes. Unless the undocumented use_encoding attribute is
set, it seems that all data should be bytes throughout (e.g., the
terminator, inputs to push methods, etc.).
I have no idea if the use_encoding attribute is officially blessed or
not. However, to avoid "magic behavior", I'm guessing that it would be
better practice to be explicit in one's use of bytes vs. text rather
than having take place in the internals of asynchat. Advice welcome.

Quote from http://docs.python.org/3.0/c-api/arg.html, regarding the "s"
argument:
"""
s (string or Unicode object) [const char *]
Convert a Python string or Unicode object to a C pointer to a
character string. You must not provide storage for the string itself; a
pointer to an existing string is stored into the character pointer
variable whose address you pass.
"""
I guess the phrase "you must not provide storage" is a failed
translation and not meant like that. It should say "you are not required
to provide storage". It's confusing to have such strong wording without
reason.

Message-ID: <1230252107.45.0.57470787699.issue4747@psf.upfronthosting.co.za>
New submission from Gabriel Genellina <gagsl-py2 at yahoo.com.ar>:
Attempting to directly execute a script containing non-ASCII
characters in its name or path raises SyntaxError.
The script contents are mostly irrelevant, except it must contain an
encoding declaration (with *any* encoding, real or inexistent).
Running "python foo.py" works, but invoking it directly as "foo.py"
raises `SyntaxError: None`, or sometimes `SyntaxError: encoding
problem: with BOM` (no BOM is present in the source file, a plain
ASCII text file).
C:\TEMP>cd ?????
C:\TEMP\?????>type test.py
# -*- coding: ascii -*-
C:\TEMP\?????>C:\Apps\Python30\python.exe test.py
C:\TEMP\?????>test.py
SyntaxError: None
To avoid any doubt, the file has no strange characters:
C:\TEMP\?????>python -c "print(repr(open('test.py','rb').read()))"
'# -*- coding: ascii -*-\r\n'
and .py files are associated with the same interpreter:
C:\TEMP\?????>assoc .py
.py=Python.File
C:\TEMP\?????>ftype Python.File
Python.File="C:\Apps\Python30\python.exe" "%1" %*
The same thing happens if the file name contains any non-ASCII
character (the path may be pure ASCII).

It seems that RotatingFileHandler is experiencing an issue when

I tried the code on Python 2.5.2 and 2.5.4 under Windows XP SP 2, with
the same results. To reproduce run the attached scripts few times. The
first time the handlers attempt to rotate the log files the error
message above is received.
In addition to crashing the application, log files are getting lost as
a result, which is a serious issue.
I have seen few complaints about this issue, but tickets were closed
without a real resolution to the issue (unless I missed something)

Message-ID: <1230298756.92.0.632482701363.issue4751@psf.upfronthosting.co.za>
New submission from ebfe <knabberknusperhaus at yahoo.de>:
The hashlib functions provided by _hashopenssl.c hold the GIL all the
time although the underlying openssl-library is basically thread-safe.
I've attached a patch (svn diff) which basically does four things:
* If python is compiled with thread-support, the EVPobject is extended
by an additional PyThread_type_lock which protects the objects individually.
* The 'update' function releases the GIL if the to-be-hashed object is a
Bytes-object and therefor provides trustworthy locking (all other types,
including subclasses, are not trustworthy!). This allows multiple
threads to do hashing in parallel.
* The EVP_hash function removes duplicated code.
* The situation regarding unicode objects is now more meaningful. Upon
passing a unicode-string to the .update() function, the original hashlib
throws a "TypeError: object supporting the buffer API required" which is
confusing. I think it's perfectly valid not to accept unicode-strings as
input and people should required to call str.encode() upon their strings
before hashing, so a well-defined byte-representation of their strings
get hashed. Therefor I patched the MY_GET_BUFFER_VIEW_OR_ERROUT-macro to
throw "TypeError: Unicode-objects must be encoded before hashing". This
also fixes issue #1118
I've tested this patch and did not run into problems. CPU occupancy
relies on the buffer-size passed to .update() as releasing the GIL is
basically not worth the effort for very small buffers. More testing may
be needed...

Subject: [New-bugs-announce] [issue4753] Faster opcode dispatch on gcc
In-Reply-To: <1230325778.98.0.752974375077.issue4753@psf.upfronthosting.co.za>
Message-ID: <1230325778.98.0.752974375077.issue4753@psf.upfronthosting.co.za>
New submission from Antoine Pitrou <pitrou at free.fr>:
This patch implements what is usually called "threaded code" for the
ceval loop on compilers which support it (only gcc). The idea is that
there is a separate opcode dispatch epilog at the end of each opcode,
which allows the CPU to make much better use of its branch prediction
capabilities. The net result is a 15-20% average speedup on pybench and
pystone, with higher speedups on very tight loops (see below for the
full pybench result chart).
The opcode jump table is generated by a separate script which is called
as part of the Makefile (just as the asdl building script already is).
On compilers other than gcc, performance will of course be unchanged.

Subject: [New-bugs-announce] [issue4755] Common path prefix
In-Reply-To: <1230350435.61.0.221193783724.issue4755@psf.upfronthosting.co.za>
Message-ID: <1230350435.61.0.221193783724.issue4755@psf.upfronthosting.co.za>
New submission from Skip Montanaro <skip at pobox.com>:
os.path.commonprefix returns the common prefix of a list of paths taken character-by-character. This can
return invalid paths. For example, os.path.commonprefix(["/export/home/dave", "/etc/passwd"]) will return "/e", which likely has no meaning as a path, at least in the context of the input list.
Ideally, os.path.commonprefix would operate component-by-component, but people rely on the existing
character-by-character operation, so it has been so far impossible to change semantics. There are several
possible ways to solve this problem. One, change how commonprefix behaves. Two, add a flag to
commonprefix to allow it to operate component-by-component if desired. Three, add a new function to
os.path.
I personally prefer the first option. Aside from the semantic change though, it presents the problem of
where to put the old definition of commonprefix. It's clearly of some use or people wouldn't have co-
opted it for non-filesystem use. It could go in the string module, but that's been living a life in limbo
since the creation of string methods. People have been loathe to add new functionality there. The second
option seems to me like would just be a hack on top of already broken behavior and probably require the
currently slightly broken behavior as the default to boot, so I won't go there. Since option one is
perhaps not going to be available to me, I've implemented the third option as a new function,
commonpathprefix. See the attached patch. It includes test cases and documentation changes.

It's stronger than "you are not required to": if you do provide storage
(by allocating memory), then this memory most likely will be garbage,
and you must not attempt to free it afterwards (as doing so would cause
a crash).

New submission from STINNER Victor <victor.stinner at haypocalc.com>:
Python 2.x allows to encode any byte string (str) and ASCII unicode
string (unicode):
$ python
Python 2.5.1 (r251:54863, Jul 31 2008, 23:17:40)
>>> import zlib
>>> zlib.compress('abc')
"x\x9cKLJ\x06\x00\x02M\x01'"
>>> zlib.compress(u'abc')
"x\x9cKLJ\x06\x00\x02M\x01'"
>>> zlib.compress(u'abc\xe9')
...
UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' ...
I'm not sure that this behaviour was really wanted become the
decompress operation is not symetric (the result type is always byte
string):
$ python
Python 2.5.1 (r251:54863, Jul 31 2008, 23:17:40)
>>> import zlib
>>> zlib.decompress("x\x9cKLJ\x06\x00\x02M\x01'")
'abc'
---
Python 3.0 accepts any string: bytes or characters. But decompress
always produce bytes string:
$ ./python
Python 3.1a0 (py3k:67926M, Dec 26 2008, 23:59:07)
>>> import zlib
>>> zlib.compress(b'abc')
b"x\x9cKLJ\x06\x00\x02M\x01'"
>>> zlib.compress('abc')
b"x\x9cKLJ\x06\x00\x02M\x01'"
>>> zlib.compress('abc\xe9')
b'x\x9cKLJ>\xbc\x12\x00\x06\xca\x02\x93'
>>> zlib.compress('abc\xe9'.encode('utf-8'))
b'x\x9cKLJ>\xbc\x12\x00\x06\xca\x02\x93'
>>> zlib.decompress(b'x\x9cKLJ>\xbc\x12\x00\x06\xca\x02\x93')
b'abc\xc3\xa9'
The most strange operation is the decompression of an unicode string:
$ ./python
>>> zlib.decompress('x\x9cKLJ>\xbc\x12\x00\x06\xca\x02\x93')
...
zlib.error: Error -3 while decompressing data: incorrect header check
---
I propose to change zlib API to reject unicode string and use explicit
conversion to/from bytes. Functions/methods:
- compress(bytes, ...)
- decompress(bytes, ...)
- <compress object>.compress(bytes, ...)
- <decompress object>.decompress(bytes, ...)
- crc32(bytes, value=0)
- adler(bytes, value=1)
Note: binascii.crc32() already rejects unicode string.
The behaviour may kept in Python 3.0.x and only changed in Python 3.1.

New submission from David M. Beazley <beazley at users.sourceforge.net>:
I have recently completed a pretty thorough survey of library
documentation for Python 3.0 in conjunction with an update I'm making to
my book. This issue is not so much a bug as a documentation request.
For all of the library modules related to network programming, it would
be extremely useful to be much very explicit about what methods work
with strings and what methods requires byte. So many of these modules
operate on small fragments of data (e.g., send a request, add a header,
parse a query string, etc.). Sometimes using a string is okay,
sometimes it's not and sadly, it's not often predictable. Part of the
problem is that the documentation has been written for a Python 2 world
where text strings and binary data were interchangeable.
Anyways, this request minimally covers these modules:
ftplib
smtplib
nntplib
http.*
urllib.*
xmlrpc.*
socketserver
asynchat
asyncore
If there is interest, I can submit more detailed notes from my own work,
but I'm not sure how the documentation maintainer would want this.
Separate issue for each? Added as comments here? Please advise.

New submission from Antoine Pitrou <pitrou at free.fr>:
Very recent POSIX versions have introduced a set of functions named
openat(), unlinkat(), etc. (*) which allow to access files relatively to
a directory pointed to by a file descriptor (rather than the
process-wide current working directory). They are necessary to implement
thread-safe directory traversal without any symlink attacks such as in
#4489. Providing Python wrappers for these functions would help creating
higher-level abstractions for secure directory traversal on platforms
that support it.
(*) http://www.opengroup.org/onlinepubs/9699919799/functions/openat.html
?The purpose of the openat() function is to enable opening files in
directories other than the current working directory without exposure to
race conditions. Any part of the path of a file could be changed in
parallel to a call to open(), resulting in unspecified behavior. By
opening a file descriptor for the target directory and using the
openat() function it can be guaranteed that the opened file is located
relative to the desired directory.?

New submission from STINNER Victor <victor.stinner at haypocalc.com>:
PyFile_FromFd() never changes the name of new created file object:
$ ./python -c "import sys; print(sys.stdout.buffer.name,
sys.stdout.name)"
0 0
Expected result: <stdout> <stdout>.
---
Binary mode:
- with buffering == 0, the file object is a FileIO. Changing the name
can be done with: file._name=new_name
- with buffering != 0, the file object is a BufferedXXX() and
file.raw is a FileIO. So we have to set: file.raw._name=new_name
If text mode, the file object is a TextIOWrapper and file.raw is a
BufferedXXX() (buffering=0 is forbidden for text file). So changing
the name can be done with: file.raw.raw._name=newname.
I'm not sure of the classes/types.
Note: PyFile_FromFd() shouldn't use PyErr_Clear() if changing the name
fails.

The documentation for PyErr_GivenExceptionMatches states that "If given is
NULL, a memory access violation will occur." However, looking at the
code, this is not the case: the function returns 0 (read: false).
It appears, rather, that this function always succeeds.

Py2.4 and 2.5 (and probably other 2.x releases too):
>>> try: f=open('existing_dir')

...
None
(expected result: "existing_dir")
Py3.0 (and possibly 3.1 too):
>>> try: f=open('existing_dir')
... except IOError as exc: print(exc.filename)
...
None
(expected result: "existing_dir")
But no problems with:
open('existing_dir', 'w')

open('not_existing_file')
=> exc.filename=='not_existing_file'

It may be similar to issue #599163

New submission from Alex Fainshtein <alex_fainshtein at netzero.net>:
How to reproduce:
1. Start IDLE -> "Python Shell" window opens.
2. Open Options|"Configure Idle...".
3. In "idle" dialog select "Keys" tab.
4. Click "Set as New Custom Key Set" button.
5 In "New Custom Key Set" dialog, type a name, click "Ok".
4. Click "Apply". Then notice that in the folder
C:\Documents and Settings\<user>\.idlerc,
two new files appear, config-keys.cfg and config-main.cfg. The
contents of the latter is
[Keys]
default = 0
name = <Key Set Name>
SO FAR ALL IS OK.
5. Now go back to "idle" dialog, click "Delete Custom Key Set", then
"Apply". Notice that config-keys.cfg file disappeared, but
config-main.cfg neither disappeared nor changed. My guess, THIS IS THE BUG.
6. Now click "Ok" - no reaction. Click "Cancel" - crash: the Python
windows disappear. Try to restart IDLE - it WOULD NOT START until
config-main.cfg is manually deleted.

precise about strings/bytes

Message-ID: <1230564109.29.0.851125901537.issue4766@psf.upfronthosting.co.za>
New submission from David M. Beazley <beazley at users.sourceforge.net>:
Documentation for the email package needs to be more clear about the
usage of strings and bytes. In particular:
1. All operations that parse email messages such as message_from_file()
or message_from_string() operate on *text*, not binary data. So,
the file must be opened in text mode. Strings must be text strings,
not binary strings.
2. All operations that set/get the payload of a message operate on
byte strings. For example, using m.get_payload() on a Message
object returns binary data as a byte string.
Opinion: There might be other bug reports about this, but I'm not
advocating that the email module should support reading messages from
binary mode files or byte strings. Email and MIME were originally
developed with the assumption that messages would always be handled as
text. Minimally, this assumed that messages would stay intact even if
processed as 7-bit ASCII. By extension, everything should still work
if processed as Unicode. So, I think the use of text-mode files is
entirely consistent with this if you wanted to keep the module "as is."
There may be some confusion on this matter because if you're reading or
writing email messages (or sending them across a socket), you may
encounter messages stored in the form of bytes strings instead of text.
People will then wonder why a byte string can't be parsed by this module
(especially given that email messages only use character values in the
range of 0-127).

However, it's confusing because none of these classes are actually found

Suggest either using the full proper name:

MIMEText()

bytes/str crash - b64encode() bug?

Message-ID: <1230571301.08.0.30132908931.issue4768@psf.upfronthosting.co.za>
New submission from David M. Beazley <beazley at users.sourceforge.net>:
The email.generator.Generator class does not work correctly message
objects created with binary data (MIMEImage, MIMEAudio, MIMEApplication,
etc.). For example:
>>> from email.mime.image import MIMEImage
>>> data = open("IMG.jpg","rb").read()
>>> m = MIMEImage(data,'jpeg')
>>> s = m.as_string()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/tmp/lib/python3.0/email/message.py", line 136, in as_string
g.flatten(self, unixfrom=unixfrom)
File "/tmp/lib/python3.0/email/generator.py", line 76, in flatten
self._write(msg)
File "/tmp/lib/python3.0/email/generator.py", line 101, in _write
self._dispatch(msg)
File "/tmp/lib/python3.0/email/generator.py", line 127, in _dispatch
meth(msg)
File "/tmp/lib/python3.0/email/generator.py", line 155, in
_handle_text
raise TypeError('string payload expected: %s' % type(payload))
TypeError: string payload expected: <class 'bytes'>
>>>
The source of the problem is rather complicated, but here is the gist of
it.
1. Classes such as MIMEAudio and MIMEImage accept raw binary data as
input. This data is going to be in the form of bytes.
2. These classes immediately encode the data using a base64 encoder.
This encoder uses the library function base64.b64encode().
3. base64.b64encode() takes a byte string as input and returns a byte
string as output. So, even after encoding, the payload of the message
is of type 'bytes'
4. When messages are generated, the method Generator._dispatch() is
used. It looks at the MIME main type and subtype and tries to dispatch
message processing to a handler method of the form
'_handle_type_subtype'. If it can't find such a handler, it defaults
to a method _writeBody(). For image and audio types, this is what
happens.
5. _writeBody() is an alias for _handle_text().
6. _handle_text() crashes because it's not expecting a payload of type
'bytes'.
Suggested fix:
I think the library function base64.b64encode() should return a string,
not bytes. The whole point of base64 encoding is to take binary data
and encode it into characters safe for inclusion in text strings.
Other fixes:
Modify the Generator class in email.generator to properly detect bytes
and use a different _handle function for it. For instance, maybe add a
_handle_binary() method.

bytes

Message-ID: <1230572153.22.0.954048343235.issue4769@psf.upfronthosting.co.za>
New submission from David M. Beazley <beazley at users.sourceforge.net>:
The whole point of base64 encoding is to safely encode binary data into
text characters. Thus, the base64.b64decode() function should equally
accept text strings or binary strings as input. For example, there is a
reasonable expectation that something like this should work:
>>> x = 'SGVsbG8='
>>> base64.b64decode(x)
b'Hello'
>>>
In Python 3, you get this exception however:
>>> base64.b64decode(x)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/tmp/lib/python3.0/base64.py", line 80, in b64decode
raise TypeError("expected bytes, not %s" % s.__class__.__name__)
TypeError: expected bytes, not str
>>>
I realize that there are encoding issues with Unicode strings, but
base64 encodes everything into the first 127 ASCII characters. If the
input to b64decode is a str, just do a encode('ascii') operation on it
and proceed. If that fails, it wasn't valid Base64 to begin with.
I can't think of any real negative impact to making this change as long
as the result is still always bytes. The main benefit is just
simplifying the decoding process for end-users.
See issue 4768.

New submission from David M. Beazley <beazley at users.sourceforge.net>:
See Issue 4869 for a related bug.
Most of the functions in binascii are meant to go from binary data to
textual representations (hex digits, base64, binhex, etc.). There are
numerous problems:
1. Misleading error messages. For example:
>>> binascii.b2a_base64("Some text")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: b2a_base64() argument 1 must be string or buffer, not str
>>> binascii.crc32("Some text")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: crc32() argument 1 must be string or buffer, not str
>>>
Huh? Didn't I just pass a string? Error message should say "argument
1 must be bytes or buffer, not str".
This problem shows up with most of the other encoding functions too
(i.e., b2a_uu).
2. Expected behavior with encoding/decoding.
The functions in this module are going from binary to text. To be
consistent, I think the result of encoding operations such as b2a_uu(),
b2a_base64(), should be strings, not bytes.
Similarly, decoding operations are going from text back to bytes. I
think the input arguments should be allowed to be str (in addition to
bytes if you want).

The hashlib documentation has incorrect examples showing the use of the

b'a4337bc45a8fc544c03f52dc550cd6e1e87021bc896588bd79e901e2'

b'cc4a5ce1b3df48aec5d22d1f16b894a0b894eccc'

However, the result of h.hexdigest() is of type 'str', not bytes. Actual
output:
>>> h.hexdigest()
'cc4a5ce1b3df48aec5d22d1f16b894a0b894eccc'

Sure would be nice if that string of hex digits was easy to decode back
into a binary string.
>>> import binascii
>>> b = binascii.a2b_hex(h.hexdigest())
>>>
Hmmm. So *SOME* of the functions in binascii do accept Unicode strings.

New submission from David M. Beazley <beazley at users.sourceforge.net>:
A file-like object u returned by the urlopen() function in both Python
2.6/3.0 has a method info() that returns a 'HTTPMessage' object. For
example:
::: Python 2.6
>>> from urllib2 import urlopen
>>> u = urlopen("http://www.python.org")
>>> u.info()
<httplib.HTTPMessage instance at 0xce5738>
>>>
::: Python 3.0
>>> from urllib.request import urlopen
>>> u = urlopen("http://www.python.org")
>>> u.info()
<http.client.HTTPMessage object at 0x4bfa10>
>>>
So far, so good. HTTPMessage is defined in two different modules, but
that's fine (it's just library reorganization).
Two major problems:
1. There is no documentation whatsoever on HTTPMessage. No description
in the docs for httplib (python 2.6) or http.client (python 3.0).
2. The HTTPMessage object in Python 2.6 derives from mimetools.Message
and has a totally different programming interface than HTTPMessage in
Python 3.0 which derives from email.message.Message. Check it out:

I know that getting rid of mimetools was desired, but I have no idea if
changing the API on HTTPMessage was intended or not. In any case, it's
one of the only cases in the entire library where the programming
interface to an object radically changes from 2.6 -> 3.0.
I ran into this problem with code that was trying to properly determine
the charset encoding of the byte string returned by urlopen().
I haven't checked whether 2to3 deals with this or not, but it might be
something for someone to look at in their copious amounts of spare time.

New submission from Alain Spineux <alain.spineux at gmail.com>:
This is a test script, to help me to understand why I have unexpected
result in application.
But I got a more unexpected result, and probably wrong error message
about the read-only cursor.
The full script is at the end.
I got this only one ! I restart the script after the crash, but
this has freezed my xen virtual machine after some minutes. I had to
"destroy" it and restart it.
After restart was not working anymore, blocked, not responding except to
CTRL-C
I had to drop the old DB, and then i worked again
I run python 2.5.2 inside a kolab 2.2.0 (aka openpkg) environement
on a xen centos 5.x running kernel 2.6.18-8.el5xen and glibc-2.5-12
The host is a P4 running centos 5.X and kernel 2.6.18-53.1.4.el5xen
Here are the errors, I waited for long time after the firts backtrace,
to press CTRL-C and got immediately the second backtrace.

New submission from David Morley <morley at ai.sri.com>:
There is a systemic error in the Python documentation on time (such as
<http://docs.python.org/library/time.html>). The term UTC is used
incorrectly in the documentation where the term UT1 should be used.
The difference is that UTC includes leap seconds, whereas UT1 does not (see <http://en.wikipedia.org/wiki/Coordinated_Universal_Time>). The
conversion routines ignore leap seconds, e.g., (time.mktime((2000,1,1,12,0,0,0,0,0))-
time.mktime((1990,1,1,12,0,0,0,0,0))) returns an exact multiple of
24*60*60 and does not include all the leap seconds added between those
dates. Using UT1 is more sensible that using UTC, since with UTC it is
impossible to know when future leap seconds will be added, and hence
impossible to convert future times to a number of seconds past the
epoch.

Read the documentation carefully. It doesn't claim that mktime uses UTC,
and claiming that it uses UT1 would be equally incorrect. Instead,
mktime uses local time (as documented). Whether that includes leap
seconds or not depends on the definition of your time zone in your
operating system.
Also notice that the Unix time (time_t) is discontinuous with respect
to leap seconds; each day time_t advances by 86400 seconds even if there
was a leap second on that day; see
http://en.wikipedia.org/wiki/Unix_time
So even if your time zone includes leap seconds, then mktime still
correctly computes the difference as multiple of 86400.
Which specific other usage of UTC do you also consider incorrect?

I've just installed Python 3.0 (with Tkinter) on Windows Vista, but I
can't import Tkinter : "No module named Tkinter"
When installing Python 2.6, it works.
Why ?
Thank you.

I needed the attached patch to install a framework build of Python3 (py3k

I haven't applied the patch to the repository because I don't know if
there's a reason for not using RUNSHARED in the first place.

(Big A** Warning Message)

Message-ID: <1230657409.93.0.0443603821797.issue4783@psf.upfronthosting.co.za>
New submission from David M. Beazley <beazley at users.sourceforge.net>:
The json module is described as having an interface similar to pickle:
json.dump()
json.dumps()
json.load()
json.loads()
I think it would be a WISE idea to add a huge warning message to the
documentation that these functions should *NOT* be used to serialize or
unserialize multiple objects on the same file stream like pickle. For
example:
f = open("stuff","w")
json.dump(obj1, f)
json.dump(obj2, f) # NO! FLAMING DEATH!
f = open("stuff","r")
obj1 = json.load(f)
obj2 = json.load(f) # NO! EXTRA CRIPSY FLAMING DEATH!
For one, it doesn't work. load() actually reads the whole file into a
big string and tries to parse it as a single object. If there are
multiple objects in the file, you get a nasty exeption. Second, I'm
not even sure this is technically allowed by the JSON spec.
As far as I call tell, concatenating JSON objects together in the same
file falls into the same category as concatenating two HTML documents
together in the same file (something you just don't do).
Related: json.load() should probably not be used on any streaming input
source such as a file wrapped around a socket. The first thing it does
is consume the entire input by calling f.read()---which probably not
what someone is expecting (and it might even cause the whole program to
hang).

Message-ID: <1230658934.34.0.991784557371.issue4785@psf.upfronthosting.co.za>
New submission from David M. Beazley <beazley at users.sourceforge.net>:
The strict parameter to JSONDecoder() is undocumented and is confusing
because someone might assume it has something to do with the encoding
parameter or the general handling of parsing errors (which it doesn't).
As far as I can determine by reading the source, strict determines
whether or not JSON strings are allowed to contain literal newlines in
them or not. For example (note: loads() passes its parameters to
JSONDecoder):
>>> s = '{"test":"Hello\nWorld"}'
>>> print(s)
{"test":"Hello
World"}
>>> json.loads(s)
Traceback (most recent call last):
...
File "/tmp/lib/python3.0/json/decoder.py", line 159, in JSONString
return scanstring(match.string, match.end(), encoding, strict)
ValueError: Invalid control character at: line 1 column 14 (char 14)
>>> json.loads(s,strict=False)
{'test': 'Hello\nWorld'}
>>>
Note in this last example how the result has the literal newline
embedded in it when strict is set False.

Not a bug, but a question to developers:

plans to rename it to xml.etree.elementtree?
Just curious.

New submission from Damian <atagar1 at gmail.com>:
Hi, in switching to Python 3.0 I've run into an issue with displaying
Unicode characters via curses. In Python 2.x a simple hello-world looks
like:
#!/usr/bin/python
# coding=UTF-8
import curses
import locale
locale.setlocale(locale.LC_ALL,"")
def doStuff(stdscr):
message = u"hello ???!"
stdscr.addstr(0, 0, message.encode("utf-8"), curses.A_BLINK)
stdscr.getch() # pauses until a key's hit
curses.wrapper(doStuff)
This works. However, when I try to come up with an equivalent for Python
3.0:
#!/usr/bin/python
import curses
import locale
locale.setlocale(locale.LC_ALL,"")
def doStuff(stdscr):
message = "hello ???!"
stdscr.addstr(0, 0, message, curses.A_BLINK)
stdscr.getch() # pauses until a key's hit
curses.wrapper(doStuff)
It fails (printing gibberish to the console). It seems that the problem
is that the curses module isn't respecting the system's preferred
encoding (utf-8) which was set via the setlocale function (as per
instructions at
http://docs.python.org/dev/3.0/library/curses.html#module-curses).
My apologies in advance if this is my mistake. Cheers! -Damian

New submission from Christopher Mahan <chris.mahan at gmail.com>:
The python program crashes (stops responding) both from the command line
and in IDLE (ver 3.0), after listing all the files in the approprate
directory, both with ftp.dir() and with ftp.retrlines('LIST') (see prog
listing below).
I have to close the window (both window shell and IDLE). No other key
combo responds.
Python env (from IDLE):
Python 3.0 (r30:67507, Dec 3 2008, 20:14:27) [MSC v.1500 32 bit
(Intel)] on win32
Program:
import ftplib
ftp = ftplib.FTP('ftp.edgecastcdn.net', user='theusername',
passwd='thepassword')
ftp.cwd('chrismahan-675')
ftp.dir()
#ftp.retrlines('LIST')
ftp.close()
The username and password are correct.
I am able to use the ftp resource with filezilla (3.1.6) with no problem.
This runs on a Windows Server 2003 Standard Edition, Service Pack 2.
This is also a completely clean install of Python 3.0. I installed it,
then wrote this program.
Python 2.5 is installed on this server and runs fine.

should use the given "interp" parameter

New submission from Guilherme Polo <ggpolo at gmail.com>:
Right now PythonCmd is using the Tcl interpreter stored in self->interp,
but this is unsafe and since it is a Tcl_CmdProc it already receives the
Tcl interpreter as a parameter. Using the interpreter in self->interp is
unsafe because Python might deallocate this TkappObject and then
PythonCmd could be invoked later, and using the interpreter given to the
Tcl_CmdProc is guaranteed to be safe by Tcl.
To reproduce this I needed a debug build and also needed to run the
example below in the interpreter:
>>> import tkFileDialog
>>> tkFileDialog.askdirectory() # here I both windows, then:
>>> Segmentation fault
There are other ways to reproduce this but I can't remember them
offhand, I know there are other ways because I've hit this same problem
in another python <-> tcl bridge by doing something else.
The patch could be expanded to remove the use of "self" in
PythonCmd_Clientdata, but given another wish I have -- to move to
Tcl_CreateObjCommand -- self would be needed again.

New submission from Lenard Lindstrom <len-l at telus.net>:
http://www.python.org/doc/2.6/glossary.html
The decorator entry in the Python 2.6 documentation incorrectly
describes a decorator as "merely syntactic sugar". It is not, as this
example shows:
>>> def decorator(f):
f.prev = globals()[f.__name__]
return f
>>> func = 0
>>> def func():
pass
>>> func = decorator(func)
>>> func.prev
<function func at 0x00C748F0>
>>> func = 0
>>> @decorator
def func():
pass
>>> func.prev
0
This distinction could be useful in building multi-methods, for example.

Subject: [New-bugs-announce] [issue4794] garbage collector blocks and takes
worst-case linear time wrt number of objects

Message-ID: <1230752086.58.0.537070994703.issue4794@psf.upfronthosting.co.za>
New submission from darrenr <python-roundup at dranalli.com>:
Python's garbage collector holds GIL during collection and doesn't
provide any method of interruption or concurrency with other Python
threads within a single Python VM. This can be a problem for realtime
applications. The worst-case performance of the garbage collector takes
linear time with respect to the number of Python objects that could
potentially be involved in a garbage cycle. I've attached timings taken
on a Core 2 Quad 2.4 GHz (WinXP Pro, 3GB RAM), with ever-increasing
numbers of objects. The gc at worst takes upwards of 3 seconds before
the process runs out of memory.
If gc periodically released the GIL it would allow it to be put in a
separate thread, but as it stands it blocks the Python VM for periods of
time that are too long for realtime interactive applications.
Alternatively a gc that is incremental by default would eliminate the
need for a second thread.

Subject: [New-bugs-announce] [issue4795] inspect.isgeneratorfunction
inconsistent with other inspect functions

Message-ID: <1230763627.06.0.589317806347.issue4795@psf.upfronthosting.co.za>
New submission from Steven D'Aprano <steve at pearwood.info>:
The inspect isSOMETHING() functions all return True or False, except
for isgeneratorfunction(), which returns True or None.
The body of the function is very brief:
if (isfunction(object) or ismethod(object)) and \
object.func_code.co_flags & CO_GENERATOR:
return True
The behaviour can be made consistent with the other routines by either
appending "else: return False", or changing the body to:
return bool(
(isfunction(object) or ismethod(object)) and
object.func_code.co_flags & CO_GENERATOR)

Subject: [New-bugs-announce] [issue4796] Decimal to receive from_float method
In-Reply-To: <1230764359.55.0.955763939043.issue4796@psf.upfronthosting.co.za>
Message-ID: <1230764359.55.0.955763939043.issue4796@psf.upfronthosting.co.za>
New submission from Steven D'Aprano <steve at pearwood.info>:
In the PEP for Decimal, it was discussed that the class should have a
from_float() method for converting from floats, but to leave it out of
the Python 2.4 version:
http://www.python.org/dev/peps/pep-0327/#from-float
Following discussions with Mark Dickinson, I would like to request
that this now be implemented.
The suggested API is:
Decimal.from_float(floatNumber, [decimal_places])
At the risk of derailing the request, I wonder whether it is better to
give a context rather than a number of decimal places?
Pro: better control over conversion, as you can specify rounding
method as well as number of decimal places.
Con: more difficult for newbies to understand.
Semi-pro: float to decimal conversions are inherently tricky, perhaps
we should be discouraging newbies from blindly calling from_float()
and make the (hypothetical) context argument mandatory rather than
optional?
