Martin, the test is failing because the dist is missing the file:
Lib/test/Sine-1000Hz-300ms.aif . That file is in SVN and was included
in the rc1 tarball.

New submission from Guilherme Polo <ggpolo at gmail.com>:
The attached patch removes the return statements from proxy_forget and
proxy_place since these methods aren't supposed to return anything.
It also fixes the docstring for the identify and paneconfigure methods.
While fixing the docstring in paneconfigure I considered as important to
rename "tagOrId" to "window", so the documentation and the method
signature get in agreement and also makes sense.

The other changes in the patch are about removing unneeded return

body

Message-ID: <1243871968.86.0.721781511059.issue6161@psf.upfronthosting.co.za>
New submission from Guthur <guthur at hotmail.com>:
HTTPResponse does not store the HTTP response body while it does store
the response headers, which in my opinion makes it rather useless as a
HTTP response abstraction object.
The only way to obtain the response body is to call HTTPResponse.Read
([amt]) and store the body seperately, this must also be carried out
before the connection is closed, which makes no sense as the server
serves both HEADERs and BODY together.
I can think of no real reason why this should be the case HTTP already
provides a method for receiving just the headers with the HEAD request
type.
Keynotes: HTTPResponse should store the body, if received, as well as
the headers.

As signals are only delivered to the main thread, what should happen
when the main thread dies? Currently, the signal mask is not unset in
any other thread, so when the main thread dies, all signals set in the
mask are simply ignored. Perhaps an other thread could be selected as
the main thread?
The accompanied file demonstrates this behavior.

New submission from Guilherme Polo <ggpolo at gmail.com>:
Hi,
I've noticed some minor problems in Tkinter.Scrollbar that would be good
to be addressed. The activate method never returns a value and it also
doesn't accept to be called without an element -- which is accepted by
tcl. When an element is not especified, the current active element
should be returned. It's signature is also a bit strange, I don't see
why it has a parameter named "index" while it never takes an index but
an element.
The second problem is about the set method. It accepts any amount of
arguments, but it only needs to accept two. Passing a tuple in the form
of (number, number) to it isn't accepted, so I don't see much reason to
continue with an *args there.

If you again double click on another class or function name, the new
code section should be highlighted in the Editor Window but isn't.
Nothing happens. You have to first close the Class Browser window,
reopen it and double click on another name to select it the Editor Window.
In the Windows versions, successive double clicking will highlight the

In the final example in the multiprocessing package on
http://docs.python.org/3.0/whatsnew/2.6.html#pep-371-the-multiprocessing-package
a part of the code is not properly indented. There should be one more
level of indentation starting at "#Mark pool as closed".
Patch adds that level of indentation.

New submission from Daniel Svensson <dsvensson at gmail.com>:
The documentation for inet_aton specifically says that it's used to
"Convert an IPv4 address from dotted-quad string format". This however
is not really true, it does accept dotted-quad, but not dotted-quad
alone, but also these forms from inet(3) man page:
a.b.c.d Each of the four numeric parts specifies a byte of the
address; the bytes are assigned in left-to-right order to produce the
binary address.
a.b.c Parts a and b specify the first two bytes of the binary
address. Part c is interpreted as a 16-bit value that defines the
rightmost two bytes of the binary address. This notation is suitable
for specifying (outmoded) Class B network addresses.
a.b Part a specifies the first byte of the binary address.
Part b is interpreted as a 24-bit value that defines the rightmost
three bytes of the binary address. This notation is suitable for
specifying (outmoded) Class C network addresses.
a The value a is interpreted as a 32-bit value that is
stored directly into the binary address without any byte rearrangement.
Sure, it references the man-page, but if anything it should say among
the formats it supports, dotted-quad is *one* of them.

It seems that the "flock" wrapped by the fcntl module is the one

people...)
Quote :
"""
fcntl.flock(fd, op)
Perform the lock operation op on file descriptor fd (file objects
providing a fileno() method are accepted as well). See the Unix manual
flock(3) for details. (On some systems, this function is emulated using
fcntl.)

In Python 2.6 the testRunner keyword argument to unittest.main
(TestProgram) changed from None to TextTestRunner.
This breaks test suites (like the setuptools tests) which pass in None
when not wanting to override the default.
This is easy to fix without breaking anything (but hard to test). I will
be fixing this and backporting to 2.6-maint unless there are objections.

pythonLaunch.py is a symbolic link to python 2.6.2 binary.
>From disassembling the python binary, I've found the corrosponding line

if (tstate->frame->f_exc_type != NULL)
tstate->frame is null, and an access on f_exc_type causes a segfault
(trying to access memory 0x58, see above segfaults).
I can't find any clear code path that could cause tstate->frame to go
null, any suggestions? This is preventing us from moving from python 2.4
32-bit to python 2.6 64-bit.

The documentation of the for statement in Section 7 of the Python 3

(since this is the reference it should be technically accurate)

Hi there,
I've found several minor issues in Tkinter.Listbox which are all fixed
by the attached patch.
I'm considering the bbox method should be clear in relation to the
amount of accepted arguments, which is always one. So I dropped the
*args usage there.
The curselection method has a reminder about applying getints on it, I
have done it now. I think it is fine to finally fix it, since we have
some tests for it now (at least in the tk_and_idle_maintenance branch).
The remaining changes in the patch are all about fixing docstring of
several methods in Listbox.

Do not use this bug for discussion of the topic. Use the python-dev

It should me mentioned, that the Python variable PYTHONPATH has to be
set to the directory where the multiply.py file is. This can be achieved
via export in Linux or via the PySys_SetPath() function in C (see
attachment)
It should also be mentioned that otherwise the program will have
following output:
ImportError: No module named multiply

According to PEP 291, the subprocess module is supposed to be compatible

rev 60097 introduced the use of os.closerange(), which is new in python
2.6.
Either PEP-291 needs to be revised, rev 60097 be reverted, or some sort of
fallback mechanism needs to be added.

New submission from Kristj?n Valur J?nsson <kristjan at ccpgames.com>:
It is useful to be able to disable the Nagle algoritm on socket
connections from the TCPServer. These are typically used by HTTP servers.
If combined with write buffering (setting RequestHangler.wbufsize = -1) it
can make sure that http responses are not subject to Nagle/Delayed-ack
delays. Disabling Nagle in addition to providing the buffering is
necessary to make sure that the final wfile.flush() arrives promptly, in
case a previous flush occurred and the final flush is small.
A patch is provided.

New submission from R. David Murray <rdmurray at bitdance.com>:
At the bottom of http://docs.python.org/library/fcntl.html there is a
"see also" section for the os module that says:
If the locking flags O_SHLOCK and O_EXLOCK are present in the os
module, the os.open() function provides a more platform-independent
alternative to the lockf() and flock() functions.
However, those flags are documented as being "unix only" (ie: no
windows), and in fact Linux does not support them. Alan Cox rejected
support for them back in 2000 according to this linux kernel posting:
http://lkml.indiana.edu/hypermail/linux/kernel/0005.1/1309.html
so it doesn't seem likely linux will ever support them.
Thus, to say that they provide a "more platform independent-alternative"
would appear to be false, since they appear to only be supported on BSD
and derivitives.

If a tarball has a-x perms set on its root directory, one cannot access

$ tar zxf generator_tools-0.3.5.tar.gz.
$ ls generator_tools-0.3.5/
ls: cannot access generator_tools-0.3.5/README.txt: Permission denied

sridharr at double:/tmp/i$
This is fine for GNU tar (the user can always do a chmod +x later). But
for the tarfile library, it would be better to have a flag such as
readaccess=True that will force ``extractall`` to enforce *minimum*
permissions required for the basic read access. This means, tarfile
would ignore u-x on directories and u-r on files.
The reason I make this feature request (instead of working around the
issue myself in a verbose way) is that the very reason to write a
program to extract tarball (instead of doing it manually) is to automate
it .. which automation is more effective and simple if ``extractall``
had a flag such as readaccess=True.

test_float fails on Windows with:
======================================================================
FAIL: test_format_testfile (test.test_float.IEEEFormatTestCase)

Traceback (most recent call last):

self.assertEqual(fmt % float(arg), rhs)
AssertionError: '3' != '2'
----------------------------------------------------------------------
The problematic line from formatfloat_testcases.txt is:
%.0f 2.5 -> 2
On some systems *printf() uses round-to-even. But the Windows CRT uses
round-half-away-from-zero. Consider the following C code:
printf("%+.1f -> %+.0f\n", -2.5, -2.5);
printf("%+.1f -> %+.0f\n", -1.5, -1.5);
printf("%+.1f -> %+.0f\n", +1.5, +1.5);
printf("%+.1f -> %+.0f\n", +2.5, +2.5);
On Linux this will produce:
-2.5 -> -2
-1.5 -> -2
+1.5 -> +2
+2.5 -> +2
And on Windows:
-2.5 -> -3
-1.5 -> -2
+1.5 -> +2
+2.5 -> +3

----------------------------------------------------------------------
_winreg.OpenKey() returns a PyHKEY. This type can no longer be used in
a "with" statement after r72912 introduced the SETUP_WITH opcode. The
old way used PyObject_GetAttr() to get __enter__ and __exit__ which
works fine with PyHKEY since it has a tp_getattr function. The new way
uses _PyObject_LookupSpecial() which uses the MRO and the dict of the
object.
I guess the right fix here is to update PyHKEY so it uses the modern
APIs but I don't know how to do this without breaking the special casing
for the "handle" member. Using T_INT isn't quite correct since it is a
pointer not an int.

"mac-roman" on OS X, not influenced by locale env variables

New submission from Ned Deily <nad at acm.org>:
Potential Release Blocker
The default file encoding for 3.x file objects is the value of
locale.getpreferredencoding(). Currently, the locale module behavior on
OS X deviates from other python POSIX platforms in a few unexpected and
bad ways:
1. On OS X, locale.getpreferredencoding() returns "mac-roman", an
obsolete encoding from the old "Classic" MacOS days.
2. Unlike other POSIX platforms (at least Debian Linux), the values
returned by locale.getdefaultlocale() and locale.getpreferredencoding()
on OS X are not influenced by the settings of the POSIX locale
environment variables, i.e LANG. So, unlike on the other POSIX
platforms, one can't override the (obsolete) encoding without explicitly
setting the encoding argument to open().
Compare the results from Debian Linux:
$ unset LANG

A quick look at the code shows that part of the problem is in
Modules/_localemodule.c where there is a #if defined(__APPLE__) version
of PyLocale_getdefaultlocale which appears to have its origins in MacOS
and should probably just be removed and locale.py modified to
eliminate/minimize the special case mac/darwin code. For the case of no
locale, "UTF-8" would seem to be a reasonable default. In any case,
"mac-roman" is not.

New submission from Ned Deily <nad at acm.org>:
In the Library Reference section 22.2.1 for locale, it states:
"Initially, when a program is started, the locale is the C locale, no
matter what the user?s preferred locale is. The program must explicitly
say that it wants the user?s preferred locale settings by calling
setlocale(LC_ALL, '')."
This is the case for python2.x:
$ export LANG=en_US.UTF-8
$ python2.5
Python 2.5.4 (r254:67916, Feb 17 2009, 20:16:45)

>>> import locale; locale.getlocale()

but not for 3.1:
$ python3.1

[GCC 4.3.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import locale; locale.getlocale()
('en_US', 'UTF8')
>>> locale.getdefaultlocale()
('en_US', 'UTF8')

Either the code is incorrect in 3.1 or the documentation should be
updated.

james at computer:~/testsetup$
as you will notice, the image1.jpg file does not get included in the
source distribution, and if i want to backup the entire dir/code of
everything to send to someone else.
perhaps this is a peculiarity of distutils. i realize i could write my
own manifest.in but then i have to specify *everything* and this isn't
automatic anymore.
this is definitely an issue since a user who downloads the sdist file
and runs an install will see:
error: can't copy 'image1.jpg': doesn't exist or not a regular file
this occurs because it obviously didn't get included in the sdist. the
same thing happens when sdist is run with --no-prune
i thought that perhaps i was using the wrong target so i tried a bdist
(tar.gz). in this case the image1.jpg file gets included, however
unpacking the directory doesn't give me a structure similar to the one
my code is originally maintained in.
so how do i use distutils to share *everything*, (eg: everything
specified in the setup.py directory) with my friends on the tubes?
if you want, i'll write a patch.

I don't know if something like this has been said before, so if it did
just ignore this.
I have noticed that very few programming languages use simple for loops.
Python itself doesn't have a really simple one. So here's my suggestion:
for ( value ):
# Repeats the code that follows 'value' times if value is an integer. If
it's a string or a list, repeats the code once per character or instance
on 'value'.
for ( iniINC , finalEXC ):
# Repeats the code that follows 'finalEXC - iniINC' times if they're
integers.
for ( variable , iniINC , finalEXC ):
# Assigns iniINC to variable and raises it by one until it reaches
finalEXC (not executing when it does).
#example1
for 70:
doNothing()
#example2
a = 10
for a:
doNothing()
#example3
a = 5
for ( a , 10 ):
doNothing()
#example4
i = 0
for ( i , 10 , 20 ):
doNothing()

New submission from Patrick W. <poke at BornToLaugh.de>:
I'm currently writing a library that executes predefined http requests
to a specified server. In case there is for example a HTTP Error, I want
to raise a user-defined exception that contains additional information
about when the error actually occured (so that the user of that library
gets information what happened without having to look at the actual
library code).
The in Python 3 introduced "feature" of chained exceptions (PEP 3134) is
something which is a bit annoying in that particular situation. While it
is probably good in a lot situation to know where an exception comes
from (especially when they are chained), it makes reading the actual
exception for the library user harder.
Let me show you an example:
def doXY ():
# ...
try:
page = urlopen( someRequest )
except urllib.error.URLError as e:
raise MyError( 'while doing XY', e )
# ...
MyError is an exception class, that uses the second parameter to get
additional information (for HTTPErrors the status code for example) and
compiles a detailed error message.
Before Python 3, this was a good way to prevent users from having to dig
into the code when they encounter an exception. Now however, you get
some error message like this:
-----
Traceback (most recent call last):
File "..", line ., in doXY
page = urlopen( someRequest )
File "..\lib\urllib\request.py", line 122,
in urlopen
return _opener.open(url, data, timeout)
File "..\lib\urllib\request.py", line 364,
in open
response = meth(req, response)
File "..\lib\urllib\request.py", line 476,
in http_response
'http', request, response, code, msg, hdrs)
File "..\lib\urllib\request.py", line 402,
in error
return self._call_chain(*args)
File "..\lib\urllib\request.py", line 336,
in _call_chain
result = func(*args)
File "..\lib\urllib\request.py", line 484,
in http_error_default
raise HTTPError(req.get_full_url(), code, msg, hdrs, fp)
urllib.error.HTTPError: HTTP Error 401: Unauthorized
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "..", line ., in <module>
doXY()
File "..", line ., in doXY
raise MyError( 'while doing XY', e )
MyError: 'HTTP Error 401 while doing XY (Unauthorized)'
-----
While the error message of MyError would be completely sufficient for
the user to know (and to fix by simply giving correct data) he is
flooded with a lot of information about the previously raised exception
instead with far too many unneccessary information.
So what I basically would like to have is some mechanism to prevent
Python from printing out all previous exception. As there is already the
'raise NewException from PreviousException' syntax, something like
'raise NewException from None' would be great, with explicitely stating
None to clear the buffer of previous exceptions.
Thanks you for any comments on this issue.

The behaviour of several incremental encoders is inconsistent between
2.x and py3k.
In 2.x:
>>> enc = codecs.getincrementalencoder('utf-16')()
>>> enc.getstate()
0
>>> enc.setstate(0)
>>> enc.encode(u'abc')
'\xff\xfea\x00b\x00c\x00'
In py3k:
>>> enc = codecs.getincrementalencoder('utf-16')()
>>> enc.getstate()
2
>>> enc.setstate(0)
>>> enc.encode('abc')
b'a\x00b\x00c\x00'

>From msg88801
'''
for 3.1: raising the KEEPALIVE_SIZE_LIMIT to 32 as explained and
motivated here:
msg64215
That's a simple non-disruptive change which makes a lot of sense
due to the advances in CPU designs in the last 9 years. I determined
the original value of 9 using benchmarks and similar statistics in
1999/2000.
It's probably also a good time to remove the warning, now that the
implementation has proven itself for so many years...
/* Limit for the Unicode object free list stay alive optimization.
The implementation will keep allocated Unicode memory intact for
all objects on the free list having a size less than this
limit. This reduces malloc() overhead for small Unicode objects.
At worst this will result in PyUnicode_MAXFREELIST *
(sizeof(PyUnicodeObject) + KEEPALIVE_SIZE_LIMIT +
malloc()-overhead) bytes of unused garbage.
Setting the limit to 0 effectively turns the feature off.
Note: This is an experimental feature ! If you get core dumps when
using Unicode objects, turn this feature off.
*/
#define KEEPALIVE_SIZE_LIMIT 9
'''
If this is as non-controversial as it seems, perhaps someone could
change 9 to 32 and remove "Note: This is an experimental feature..." in
time for rc2.

New submission from Alexandre Vassalotti <alexandre at peadrop.com>:
Here is a patch to add pickling support to io.BytesIO and io.StringIO.
Although they are non-trivial, the additions were made with a fair
amount of care (and love!) and thus I believe they could be included in
3.1.
Furthermore, the improved test-suite uncovered a number of bugs in the
implementation of io.StringIO. So the patch also fixes:
* fixes a memory-leak in stringio_dealloc;
* disallows bytes-like object from being used as the newline
argument of StringIO;
* and changes the exception raised by StringIO.__init__ to a
TypeError when initial_value is not a str.

Why _PyUnicode_AsString and _PyUnicode_AsStringAndSize are not public
API? They are very useful when porting extension module to Python 3,
because they have the semantic as same as PyString_AsString. For
extension author, these API can be used for replacing PyString_AsString
without any other change in code logic.
So why not make these API public? Any consideration? If we can document
these API, then C extension author can know them and use them, without
spending a lot of time to dig them out from Python source code.
Thanks!

Tkinter.Canvas and one in Misc._configure

New submission from Guilherme Polo <ggpolo at gmail.com>:
Hi,
While testing Tkinter.Canvas I've found several minor bugs that I would
prefer to see fixed. Many of them change the current Canvas api a bit,
but for better. For example, the methods "focus", "gettags", "icursor",
"index", "insert", "move" (and some others) accept arbitrary amount of
arguments, but all these tcl subcommands have a fixed amount of
arguments they accept, so I consider it is better to make this clear on
Tkinter too.
I've also found a problem in Misc._configure which is also fixed by the
attached patch. The problem is that when cnf is a string, the call
"self.tk.split(self.tk.call(_flatten((self._w, cmd, '-'+cnf))))" may
still result in an empty string causing the following statement to fail
"return (x[0][1:],) + x[1:]".
One thing that left me curious was the comment "# XXX Should use
_flatten on args" in Canvas.coords. I've tried understanding why it
should use _flatten there, but couldn't figure it out. This is a very
old comment, so maybe it is no longer true ?

It'd be nice to eventually standardize on the kwarg name used for basic
file-like args in the stdlib. print, warnings.showwarning and some
others take a file= argument whereas pprint, getpass.getpass take
stream=
print and pprint in particular should match -- though they do have a
different option set, when you're using the same options this
consistency would ease replacing:
print(obj, file=sys.stderr)
with
pprint(obj, stream=sys.stderr)

The file Lib/test/doctest_aliases.py is used by test_doctest to check
the handling of duplicate removal. The "g = f" line in this file is one
indent too far to the right so instead of creating an alias for f called
g it is just unreachable code inside of f. Since there is no alias
there is no need to remove duplicates and the test passes trivially.
I think this affects all versions but I've only checked on 2.7.

round() gives a result that is closer to

than the expected result of
697.0415795825
- it has not rounded to the closest 10th decimal digit after the decimal

New submission from Neil Muller <drnlmuller+bugs at gmail.com>:
ElementTree and cElementTree give slightly different results for
repr(Element):
>>> import xml.etree.ElementTree as ET
>>> import xml.etree.cElementTree as cET
>>> repr(ET.ElementTree('tag'))
'<Element tag at b7cf506c>'
>>> repr(cET.ElementTree('tag')
"<Element 'tag' at 0xb7c266f8>"
The quoting around the tag name is missing from ElementTree.
This inconsistency seems pointless.
Attached patch changes ElementTree to match cElementTree behaviour, and
adds a test.

encode characters that can't be represented in the specified
encoding

Message-ID: <1244410260.68.0.534028988218.issue6233@psf.upfronthosting.co.za>
New submission from Neil Muller <drnlmuller+bugs at gmail.com>:
In py3k, ElementTree no longer correctly converts characters to entities
when they can't be represented in the requested output encoding.
Python 2:
>>> import xml.etree.ElementTree as ET
>>> e = ET.XML("<?xml version='1.0'
encoding='iso-8859-1'?><body>t\xe3t</body>")
>>> ET.tostring(e, 'ascii')
"<?xml version='1.0' encoding='ascii'?>\n<body>tãt</body>"
Python 3:
>>> import xml.etree.ElementTree as ET
>>> e = ET.XML("<?xml version='1.0'
encoding='iso-8859-1'?><body>t\xe3t</body>")
>>> ET.tostring(e, 'ascii')
.....
UnicodeEncodeError: 'ascii' codec can't encode characters in position
1-2: ordinal not in range(128)
It looks like _encode_entity isn't ever called inside ElementTree
anymore - it probably should be called as part of _encode for characters
that can't be represented.

New submission from Sridhar Ratnakumar <sridharr at activestate.com>:
It'd be nice to get the encoding used by a specific Python file.
Considering that 'print' uses sys.stdout.encoding which is always set to
None when the Python process is run by subprocess, knowing the source
encoding is absolutely necessary in decoding the output generated by
that script.
eg: Run 'python setup.py --author' in the python-wifi-0.3.1 source
package as a subprocess.Popen(...) call.. and print the stdout.read()
string; you'll get encoding error.. unless you do
stdout.read().decode('latin1') .. where latin1 is specified as a coding:
line in setup.py.
The following function tries to detect the coding, but this guess work
not necessary when this is integrated with the standard library whose
implementation maps directly to that of PEP 263.
+def get_python_source_encoding(python_file):
+ """Detect the encoding used in the file ``python_file``
+ Detection is done as per http://www.python.org/dev/peps/pep-0263/
+ """
+ first_two_lines = open(python_file).readlines()[:2]
+ coding_line_regexp = ".*coding[:=]\s*([-\w.]+).*"
+
+ for line in first_two_lines:
+ m = re.match(coding_line_regexp, line)
+ if m:
+ return m.group(1)
+
+ # if no encoding is defined, use the default encoding
+ return 'ascii'

Snippet to reproduce:
import curses
scr = curses.initscr()
curses.ungetch(1025)
scr.getkey()
This is because `keyname()` in `PyCursesWindow_GetKey()` returns NULL
which is passed to `PyString_FromString()` then.
The attached patch fixes the segfault.

Apple just announced that MacOSX 10.6 ("Snow Leopard") will be released
in September, and will only support intel systems.
This means that the --with-universal-archs option is not 100% usable if
you want to build a version of Python that specifically targets this
release of the OS.
The attached patch adds the option '--with-universal-archs=intel', which
will build a 32-bit/64-bit framework for intel systemsn (that is i386
and x86_64).
Note: the patch is for the trunk, I'll port it to 3.x after review.

New submission from Ritesh Raj Sarraf <rrs at researchut.com>:
Shoudl argparse be included in the Python Standard Library.
I know we already have getopt and optparse but optparse doesn't
support many features easily. (like options without hyphen, nargs=*)
Here a little about argparse:
argparse: Python command line parser
The argparse module makes writing command line tools in Python easy.
Just briefly describe your command line interface and argparse will take
care of the rest, including:
parsing the arguments and flags from sys.argv
converting arg strings into objects for your program
formatting and printing any help messages
and much more ...
For those familiar with the optparse module from the Python standard
library, argparse improves on this module in a number of ways, including:
handling positional arguments
supporting sub-commands
allowing alternative option prefixes like + and /
handling zero-or-more and one-or-more style arguments
producing more informative usage messages
providing a much simpler interface for custom types and actions

Message-ID: <1244566538.72.0.477638958657.issue6248@psf.upfronthosting.co.za>
New submission from Kristj?n Valur J?nsson <kristjan at ccpgames.com>:
When an error occurs in a StreamRequestHandler, its wfile and rfile
members are not closed. This causes the underlaying socket to stay
alive and and it is therefore not closed, even when the SocketServer
closes it in server.close_request(). This means that a client will not
know that there is no one listening on the other end.
This is due to incorrect error handling semantics in BaseRequestHandler.
This patch fixes the error handling in BaseRequestHandler, ensuring that
request.finish() is called when request.setup() has completed.
I also add an explicit socket.shutdown() in TCPServer.close_request() to
make sure that at least a half-close occurs even in the face of socket
reference leaks.

Python currently emits bytecode for code that is unreachable (e.g.
following a return statement). This doesn't hurt anything but it takes
up space doing nothing.
This patch attempts to avoid generating any bytecode in this situation.
There's an optional warning, enabled with the -r command line switch,
which notifies you if any unreachable code is found. Running
regrtest.py with this switch produces a bit of noise but also revealed
issue6227 which looks like a real bug.

New submission from John O'Driscoll <biggerbumme at yahoo.co.in>:
feature: extension module C++ howto/example in extending-embedding/c-api
documentation
why: The embedding/extension documentation states that module
implementation in c++ is possible, without providing any guidance beyond
this. Coders more familiar/comfortable with c++ than c, writing c++ code
to expose in python, might want to create the actual python class/module
implementations in c++ classes or structs. A basic guide can help
prevent wastage of energy reinventing the wheel, and also serve as a
guide to safe/preferred style. The method outlined here can be a
starting point in finding out what that style is.
Also it seems, to my eyes at least, a little easier to 'visualise' and
apply than the equivalent in plain C (the Noddy module etc), a bit more
'systematic', and easier to understand the relation between c and python
objects. So after some trial and error, discovering the pitfalls, I am
finding it easy to create useful python classes with this recipe. Others
might also find it useful, even if only as a stimulus to find a Better Way.
Python is an object-oriented language noted for its clarity, so an
allegedly simple and clear OO implementation strategy for module classes
should be examined.
what: I've written a module currently called 'cpeepee', containing a
basic python class ,(struct TestRealDestructor in C++,
'cpeepee.destructo' in python). It has been tested with python-2.5 and
g++-4.2 on ubuntu-'hardy heron' and python-2.5/g++-3.4 on FreeBSD-6.4.
The c++ struct inherits from PyObject.(You could also inherit from
PyVarObject or other more specialised types). The most important
non-feature of this class is that it is not virtual, has no virtual
destructor or functions(in member objects virtual destructors and the
rest are OK however). Therefore the packing of ob_refcnt and friends is
correct, and casting to/from PyObject is safe(-and otherwise is not -
the PyObject* cast from such a type with virtual destructor is offset by
the size of a pointer -the vptr?-, but when python casts back to the
type - from void* or so?- the offset is not removed, leading to mayhem).
[You could also not inherit, simply put the PyObject_HEAD macro as the
first entry in the struct - could be a class also, as long as the
PyObject members(ob_refcnt, ob_type ... )were public - You would have to
write a new macro to fill in those members in the constructor's
initialiser list, but that doesn't look too hard. As it is the inherited
classes use a function and some macros (almost identical to
PyObject_HEAD_INIT(typo) ) to fill in the PyObject parent. Again, vfuncs
are out]
The destructo method and member tables are static members of
TestRealDestructor, as is its type object.(Other optional tables etc
should also be static members if provided - makes for a simple
consistent setup)
The objects constructor is called from
TestRealDestructor::type.tp_new() and passed the args and kwds arguments
it is passed, using placement new with memory obtained from
tp_alloc()(see TestRealDestructor::create() ). Being able to properly
call an object's constructor was the real motivation for writing the
code this derives from. Using C style one is stuck casting a char* to
your type and then filling its fields by hook or crook.
On error, either you could throw a c++ exception in constructor to catch
in tp_new, and convert to a python exception, or simply throw the python
exception in the constructor, and then check if PyErr_Occurred() in
tp_new() - the approach with destructo.
Since tp_new and the constructor take care of object creation, this
leaves tp_init not doing much at all. It could be used for extra checks,
or printing funky messages about preserved ham
Functions to be exposed in python API as class member functions should
static members of the class, and to do the work they call ordinary
member functions of the class object passed into the static function .
You could use global static functions(with the first arg
TestRealDestructor* say, rather than PyObject*), but that's less clear,
less systematic, less OO.
Everything can be placed in a namespace to avoid any pollution of global
namespace.
I've worked out the bugs that were obvious to me, so it should compile
and run as is, without error messages. The one compile warning I don't
know how to banish comes from the offsetof macro when setting member
offsets in the member table(as copied from the c example) - however the
object whose offset is so established works fine from python, so I think
it's a spurious warning.
If you find any issues with my approach, I'm happy to work through them,
or if you know what to do then make whatever changes you think required.
I'm happy to put any code or words I contribute on this topic to go
under python's copyright as long as I'm credited somehow(however you
normally do that). Whatever, I'm happy to contribute to such a great
project as python
sincerely

New submission from Turnaev Evgeny <xiled at yandex.ru>:
i have a very basic setup of logging in a long running daemon app..
I use TimedRotatingFileHandler with rotating at midnight.
The bug:
The last open logging file was for 2009-05-25..
app was running without logging anything for about a week or more.
After a week past something happened and daemon started to log messages,
but.. for each new message logging system creates new file.
In other words.. suppose we was idle since 2009-05-25, now it is
2009-06-10 and we want to log 10 messages..
current opened file is for 2009-05-25.. so when a first messages
arrives into logging system current must be closed. and a new file must
be opened where all 10 messages should be..
but instead logging system will log each subsequent message in files
2009-05-26, 2009-05-27, 2009-05-28..(in fact it will log in file
without a date and then when nect message arives rename current to
2009-05-26, 2009-05-27, 2009-05-28.. but is still the same) and so on,
one message per file.. i think until it reaches current date.
It is a logic error.
my logging setup looks like this:
---------

New submission from Jan Pobrislo <ccx at volny.cz>:
When using OptionParser.format_help(formatter), the formatter parameter
should be used to format all of the help message. This is not the case
for usage message, as the method get_usage() is not passed the formatter
and always uses self.formatter. I'm using python-2.6.2-r1.

seekable files
In-Reply-To: <1244648812.36.0.982521816376.issue6254@psf.upfronthosting.co.za>
Message-ID: <1244648812.36.0.982521816376.issue6254@psf.upfronthosting.co.za>
New submission from Michael K Johnson <a1237+pybugs at danlj.org>:
In python 2.6 (not 2.4, haven't checked 2.5), the __init__() method of
the TarFile class calls the tell() method on the tar file, which doesn't
work if you are reading from standard input or writing to standard
output, two very reasonable things to do with a tar file.
While there are cases where it is logical to seek within a tar file,
supporting those cases should not preclude the normal design case for
tar archives of streaming reads/writes, including tar files being
streamed between processes via pipes. If the tell() method is not
implemented for the file object, then the seek() method of TarFile (and
any other methods that can be implemented only for seekable files) can
raise a reasonable exception. Note that this also means that the next()
method should not need to seek() for non-seekable files; it should
assume that it is at the correct block and read from there.

New submission from Jason R. Coombs <jaraco at jaraco.com>:
It appears as if bdist_msi isn't properly tagging 64-bit binary builds.
When launching an .msi built by Python 2.6.2 using bdist_msi, such as
numpy found here
(https://sourceforge.net/project/showfiles.php?group_id=1369&package_id=175103),
it improperly detects the location of Python (which it gets from the
registry). If the 32-bit Python 2.6 is also installed, it finds that
version. If 32-bit Python 2.6 is not installed, it fails to find the
Python installation. Even if the proper 64-bit Python 2.6 location is
selected, the files are not installed to the Python 2.6 site-packages.
Furthermore, the registry Uninstall information is stored in the
Wow6432Node.
bdist_wininst executables appear to detect 64-bit Python and install
correctly.
I will attempt to recreate this problem with a minimal project and clean
64-bit Vista or Windows 7 machine at a later date.

Hi, in using os.utime, it's nice that you can specify `None' for the
second argument. However it would be even `nicer' to be able to specify
None for either (or potentially both) values for the argument in the
tuple. to emulate this, i've been using os.stat to read the value
beforehand, and just use os.utime with the new value, and the old one
pulled from stat()
HTH, _J
example:
os.utime('/dev/pts/1', None) WORKS
os.utime('/dev/pts/1') SHOULD WORK (allow second argument to default to
None)
os.utime('/dev/pts/1', (time.time(), None)) SHOULD WORK
os.utime('/dev/pts/1', (None, None)) SHOULD WORK
os.utime('/dev/pts/1', (None, time.time())) I GUESS SHOULD WORK
ps: if this is a feature you'd agree with, let me know any maybe i can
*try* to write a patch?

New submission from Mark Dickinson <dickinsm at gmail.com>:
The documentation for random.uniform() was recently updated to reflect
the fact that it's possible for random.uniform(a, b) to produce the
value b; see issue 4979.
In a recent c.l.p. thread, Robert Kern suggested that 'it
might be confusing to a user why random.random() returns values in a
half-open interval while random.uniform() claims a closed interval';
the thread itself confirms this potential for confusion. See
http://mail.python.org/pipermail/python-list/2009-June/715851.html
Suggested extra wording for random.uniform, from Robert Kern:
"Due to floating point arithmetic, for some values of a and b, b may or
may not be one of the possible generated results."

Hi,
Would it be possible to obtain MSVC++2008(9.0) binaries of Python 2.5.4?
We are actually stuck to this version and have problem with MSVC
runtime libraries incompatibility. I can build Python.exe from source,
but there are a lot of missing modules (external dependencies). Then,
as you already build full binaries with MSVC++7.1, I was wondering if
it would be possible for you to build MSVC++9.0(2008) binaries...
Thanks in advance.
Cheers, Bertrand.

New submission from Black Dew <blackdew at gmail.com>:
This page http://docs.python.org/install/index.html#gnu-c-cygwin-mingw
says:
"These instructions only apply if you?re using a version of Python
prior to 2.4.1 with a MinGW prior to 3.0.0 (with binutils-2.13.90-
20030111-1)"
But it seems that it is still needed for Python 2.6 with MinGW 3.15.2.
Without manually generating libpython26.a I can't compile any python
extension, geting a bunch of undefined references, for example:
c:\mingw\bin\gcc.exe -mno-cygwin -shared -s build\temp.win32-2.6

If I do generate libpython26.a - everythong works fine.

cElementTree will raise a SyntaxError on XML parsing errors, while
ElementTree will raise ExpatError. This makes changing between the two
a bit more problematic than it could be. See for example
https://lists.canonical.com/archives/bazaar/2006q3/017491.html
ElementTree 1.3 raises a ParseError, which is subclassed from
SyntaxError, which will improve the situation when it's merged, but
cElementTree should be adjusted to raise the same error.

13
>>> f.seek(0)
0

'spam ham eggs'

0

'\ufeffspam ham eggs'
Although the BOM character is a ZERO WIDTH NO-BREAK SPACE, and should
therefore not impose many problems, the behavior is inconsistent and
unexpected.
codecs.open in 2.x suffers from this same behavior.

New submission from Greg Couch <gregc at cgl.ucsf.edu>:
Sometime around Python 2.5.4, Menu.delete was changed to delete
associated entry commands (and thus plug a memory leak). This broke
Pmw.OptionMenu because it already had similar code, so when Menu.delete
was called, the commands were already gone, and a TclError was raised
saying "can't delete Tcl command".
While Pmw could be patched to workaround this bug, it seems strange that
Tkinter.Misc.deletecommand unconditionally deletes commands it knows
nothing about. All uses of deletecommand in Tkinter refer to commands
that were Tkinter.Misc._register'ed, so they should appear in the
widget._tclCommands list. So the proper solution is to only delete
commands that are still registered with the widget.
Repeat by:
import Pmw
om = Pmw.OptionMenu()
om.pack()
om.setitems(['a', 'b'])
om.setitems(['b'])

Hi, Valgrind just told me that Python calls close(-1) on
my_mmap_object.close() for memory mappings. That's because a memory
mapping has no (related) file descriptor.
Using attached warn.py, you can see the warning using strace:
$ strace -e close python warn.py 2>&1|grep -A1 12345
close(12345) = -1 EBADF (Bad file descriptor)
close(4294967295) = -1 EBADF (Bad file descriptor)
close(12345) = -1 EBADF (Bad file descriptor)
where close(4294967295) means close(-1).
Attached patch fixes this warning.

I don't know why ElementTree 1.2.6 was chosen initially.
I don't find any request for the upgrade.
So opening this one.

I wouldn't call the feature "client-side cert support" - client
certificates are already supported, and had been for a long time.
What you are adding to httplib is server certificate validation.
I find the patch incomplete, for formal and semantical reasons:
a) it doesn't come with documentation or test suite changes, and
b) it doesn't implement the typical certificate checks that browsers
do, beyond validating that the certificate is valid - e.g. also
validating that the certificate is issued to the host you are trying
to connect to.
API-wise, I'm not sure what the point of passing cert_reqs as a
parameter is - ISTM that, in httplib, if ca_certs is not None, then
cert_reqs should automatically be CERT_REQUIRED (just like it is
in get_server_certificate).
> Also, ideally this could be added to 2.6 maint (it seems like a pretty big
> hole)
It's a new feature, so it shouldn't be added to 2.6. Not sure what you
mean by "big hole".

New submission from Zooko O'Whielacronx <zooko at zooko.com>:
I've been struggling to write a function that takes UTC timestamps in
ISO-8601 strings and returns UTC timestamps in unix-seconds-since-epoch.
The first implementation used time.mktime() minus time.timezone
(http://allmydata.org/trac/tahoe/browser/src/allmydata/util/time_format.py?rev=2424
), but that doesn't work in London if the argument date is in a certain
period during the 1970's. Then there was force-the-tz-to-UTC
(http://allmydata.org/trac/tahoe/changeset/3911/src/allmydata/util/time_format.py
), but that doesn't work on Windows. Then there was
force-the-tz-to-UTC-except-on-Windows
(http://allmydata.org/trac/tahoe/changeset/3913/src/allmydata/util/time_format.py
), but that still doesn't work on Windows. Then there was this horrible
hack of converting from string-iso-8601 to localseconds with
time.mktime(), then converting from the resulting localseconds to an
iso-8601 string, then converting the resulting string back to seconds
with time.mktime(), then subtracting the two seconds values to find out
the real offset between UTC-seconds and local-seconds for the current tz
and for the time indicated by the argument
(http://allmydata.org/trac/tahoe/changeset/3914/src/allmydata/util/time_format.py
). This actually works everywhere, but it is horrible. Finally,
yesterday, someone pointed out to me that the inverse of time.gmtime()
is located in the "calendar" module and is named calendar.timegm(). Now
the implementation of our function is simple
(http://allmydata.org/trac/tahoe/changeset/3915/src/allmydata/util/time_format.py
) I suggest that timegm() be moved to the time module next to its
sibling gmtime().

New submission from Daniel Eloff <dan.eloff at gmail.com>:
The try statement at the end of hashlib.py is some of the worst python
code I've had the mispleasure of reading for a long time.
Secondly, it seems flawed in function as well as form.
__get_builtin_constructor can throw an ImportError, which seems
erroneously caught in the except (why on earth does the except span more
than the "import _hashlib"? That's bad style for precisely this reason.)
This will cause an error in the import of hashlib when there are
possibly many working hash functions already imported. Changing the:
try:
exec funcName + ' = __get_builtin_constructor(funcName)'
except ValueError:
pass
to catch ImportError as well solves the problem for me.

When creating a TarFile object that uses compression, the compressor is
always created using its default compression level.
import bz2
self.cmp = bz2.BZ2Compressor()
You can't specify the compression level (i.e. self.cmp =
bz2.BZ2Compressor(1)).

New submission from Jean-Paul Calderone <exarkun at divmod.com>:
Consider this source file:
# coding: ascii
?
It is not a valid Python program (for several reasons). The first
problem encountered is that bytes representing SNOWMAN do not fit into
ASCII, so the file cannot be decoded using the declared encoding.
If one tries to import this file, a reasonable thing happens:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "encodingfoo.py", line 2
SyntaxError: 'ascii' codec can't decode byte 0xe2 in position 0: ordinal
not in range(128)
If the builtin compile() is used instead, though, something different
happens:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<string>", line 0
SyntaxError: unknown encoding: ascii

New submission from Alex James <ac.james at shaw.ca>:
When using cPickle to pickle / unpickle an object instance whose
__dict__ contains a dictionary of NumPy Arrays (on a windows32 system),
some of the array elements have the wrong type raising a ValueError:
could not convert string to float.
On UNIX platform this error does not occur, and the data is read out in
the correct type every time.
Forcing the caller to use pickle.py module instead removed the issue.
Statements about the imprecision of cPickle (such as issue1536, 655802),
or its deprecaition (now I can't find where that was mentioned), would
assist. By contrast the current state of the documentation implies that
cPickle is better overall, and thus should be used preferentially.

The attached patch fixes a number of tests to work when -OO is given to
Python. The majority of these tests are docstring-related, either doctests
or making assertions about __doc__, with a handful of tests testing that
assert statements will trigger and another handful of distutils tests that
are looking for .pyc files.
With this applied, PYTHONOPTIMIZE=2 ./python.exe -OO Lib/test/regrtest.py
now passes for trunk.

New submission from Terry J. Reedy <tjreedy at udel.edu>:
When (at least sometimes) exceptions occur during shutdown, warnings
like the following appear:
Exception TypeError: "'NoneType' object is not callable" in ignored
This is apparently meant to be read as
Exception <<TypeError: "'NoneType' object is not callable" in ...>>
[was] ignored
instead of, for instance
Exception TypeError: "'NoneType' object is not callable" in ignored
Even when parsed correctly, it is a bit mysterious (who/what ignored the
exception?) to one not in the know and has generated more than one
python-list thread.
Suggestion (from John Machin): reword to something like
Shutdown ignored this exception: TypeError: "'NoneType' object is not
callable"
This would tell people that they might need to find out more about the
shutdown process.
Would it be permissible to change this in 3.1?

"Get a character. Note that the integer returned does not have to be in
ASCII range: function keys, keypad keys and so on return numbers higher
than 256. By default, getch() is blocking and wait indefinitely for a
key press. In nodelay() mode, -1 is returned if there is no input."

support for setup.py sdist in distutils on Windows

Message-ID: <1245245630.18.0.224607523943.issue6296@psf.upfronthosting.co.za>
New submission from Michael Foord <michael at voidspace.org.uk>:
setup.py should be able to generate tarfile distributions on Windows
without requiring tar to be on the path.
Ideally "setup.py sdist" should create the same type of archive (zip or
tarball) by default independent of platform.
At the moment it creates a zip by default on Windows and a tarball on
Linux / OS X.
Packages created on Windows also have CRLF line endings in the MANIFEST
file which is a nuisance for non-Windows consumers of distributions.

New submission from Jerry Chen <jerry at 3rdengine.com>:
Added Misc/python.pc to 'distclean' rule
Minor issue... After running ./configure, Misc/python.pc is generated
from python.pc.in. Interesting to note in the python2.7 trunk, this file
is added to the svn:ignore property of Misc/ so it doesn't show up to
svn, but in accordance with the rest of the 'distclean' rule, it makes
sense to remove the file completely.
Diff'd against r73468.

I never tried any of the 2.5.x Python builds, but I can tell you that I
built several versions in the 2.4.x series, and none of those versions
had problems compiling or linking pyexpat.
I do have expat 2.0.1 (also built with the Sun compiler in 64 bit mode)
installed on the system, but from the comments in setup.py and the
compiler output, it appears clear that the expat components that ship
with Python 2.6.x are the ones that are being compiled and attempted for
use in the link.
Please let me know if I can provide any relevant information.
Thanks,
Tim (the Enchanter)

I repeatedly find myself typing things like
"mybytestring.decode('ASCII', errors='replace')". This seems like the
natural (I'm tempted to say Pythonic) thing to do, and is more readable
(IMO) than "mybytestring.decode('ASCII', 'replace')". (replace what?).
However currently encode and decode complain that they do not take any
keyword arguments.

It is not clear what distinction Python makes between text and binary

different than cPython? And does Python automatically alter end-of-line

New submission from R. David Murray <rdmurray at bitdance.com>:
decode_header only accepts str as input. If the input contains no
encoded words, the output is str (ie: the input string) and None. If it
does contain encoded words, the output is pairs of bytes plus str
charset identifiers (or None). This makes it difficult to use this
function to decode headers, since one has to test for the special case
of str output when there are no encoded words.
I think decode_header should take bytes as input, and output (bytes.
str) pairs consistently.
In any case, the documentation is wrong since it says it returns
strings. The example is also wrong, since the actual output is:
[(b'p\xf6stal', 'iso-8859-1')]

The documentation for the print function specifies that the input

file= parameter points to a file open for binary write, the error
message produced is:
>>> out = open('temp', 'wb')
>>> print(b'abc', file=out)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: write() argument 1 must be bytes or buffer, not str
which is, to say the least, confusing, since I clearly passed print a
bytes object as argument 1.

New submission from higer <higerinbeijing at gmail.com>:
I just want to compare two files,one from windows and the other from
unix. But I do not want to compare them through reading them line by
line. Then I found there is a filecmp module which is used as file and
directory comparisons. However,when I use two same files (one from
unix,one from windows,the content of them is the same) to test its cmp
function, filecmp.cmp told me false.
Later, I found that windows use '\n\r' as new line flag but unix use
'\n', so filecmp.cmp think that they are different,then return false.
I think maybe it's a bug.
If filecmp.cmp can support two platform files with the same content
and only the diffrent last newline flag, that's would be wonderful.

Subject: [New-bugs-announce] [issue6308] termios fix for QNX breaks HP-UX
In-Reply-To: <1245342143.83.0.0806702305005.issue6308@psf.upfronthosting.co.za>
Message-ID: <1245342143.83.0.0806702305005.issue6308@psf.upfronthosting.co.za>
New submission from Michael Haubenwallner <michael.haubenwallner at salomon.at>:
The patch for issue 1722225 in Include/pyport.h to include
<sys/termio.h> before <termios.h> for QNX does break for HP-UX:
On HP-UX, 'struct termios' gets declared within <sys/termio.h>, but when
included via <termios.h> _only_. Due to the include guard, it does not
declare 'struct termios' when included via <termios.h> the second time.
This is Python-2.6.2, but the code looks unchanged in trunk. As I'm not
sure how best to fix this, for 2.6.2 here I go with:
-#ifdef HAVE_SYS_TERMIO_H
+#if defined(HAVE_SYS_TERMIO_H) && defined(__QNX__)
Thanks!

I found that if Python installed only for current user on Windows XP
Home Edition SP3 Python fails to run from Start -> Run dialog or using
ShellExecute() call. It is because it creates "App Paths" key in
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\App
Paths\Python.exe
and not in
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\App
Paths\Python.exe
Can anybody confirm this?

New submission from helgekraak <helge at kraak.info>:
Hi,
I'm neither a Python nor a Unix specialist, so please understand that I
can't give a very professional bug report.
My issue seems to be related to issues 1092502 and 1389051. When I run
archivemail with Python 2.6.2 after a couple of minutes the virtual
memory in the activity monitor suddenly goes up to more than 2 GB and
then the python process quits as it seems to have reached a limit of the
virtual memory (the virtual memory available is about 10 GB). Most of
the time the virtual memory is stable around 40 MB and only sporadically
the memory suddenly increases to values between 100 MB and 2 GB but goes
back to 40 MB again until the one time that it goes so high that the
python process quits. The error happens much faster when I use a non
secured imap connection compared to a secured connection.
I get this error message:
command: archivemail --date='23 April 2030' --include-flagged
--output-dir=/temp --copy imaps://*****:*****@*****/inbox

Subject: [New-bugs-announce] [issue6312] httplib fails with HEAD requests to
pages with "transfer-encoding: chunked"
In-Reply-To: <1245419610.47.0.800823464354.issue6312@psf.upfronthosting.co.za>
Message-ID: <1245419610.47.0.800823464354.issue6312@psf.upfronthosting.co.za>
New submission from Ezio Melotti <ezio.melotti at gmail.com>:
Try this code (youtube.com uses "transfer-encoding: chunked"):
import httplib
url = 'www.youtube.com'
conn = httplib.HTTPConnection(url)
conn.request('HEAD', '/') # send an HEAD request
res = conn.getresponse()
print res.getheader('transfer-encoding')
so far it works fine, but when you try:
res.read()
it just hung there, where "there" is:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Programs\Python26\lib\httplib.py", line 517, in read
return self._read_chunked(amt)
File "C:\Programs\Python26\lib\httplib.py", line 553, in _read_chunked
line = self.fp.readline()
File "C:\Programs\Python26\lib\socket.py", line 395, in readline
data = recv(1)
KeyboardInterrupt
If instead of youtube.com we replace the url with the one of a site that
doesn't use "transfer-encoding: chunked" (e.g. url = 'dpaste.com'),
res.read() returns an empty string.
When an HEAD request is sent, the content of the page is not returned,
so there should be no point in calling .read(), but try this:
import urllib2
class HeadRequest(urllib2.Request):
def get_method(self):
return 'HEAD'
url = 'http://www.youtube.com/watch?v=tCVqx2b-c7U'
# Note: I had this problem with this URL, the video
# is not available in my country (Finland) and it
# may work fine for other countries
req = HeadRequest(url)
page = urllib2.urlopen(req)
This is what happens here with Python 2.5:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.5/urllib2.py", line 124, in urlopen
return _opener.open(url, data)

File "/usr/lib/python2.5/urllib2.py", line 419, in error
result = self._call_chain(*args)
File "/usr/lib/python2.5/urllib2.py", line 360, in _call_chain
result = func(*args)
File "/usr/lib/python2.5/urllib2.py", line 579, in http_error_302

File "/usr/lib/python2.5/socket.py", line 291, in read

return self._read_chunked(amt)
File "/usr/lib/python2.5/httplib.py", line 548, in _read_chunked
chunk_left = int(line, 16)
ValueError: invalid literal for int() with base 16: ''
With Python 2.6 the error is slightly different:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Programs\Python26\lib\urllib2.py", line 124, in urlopen
return _opener.open(url, data, timeout)
File "C:\Programs\Python26\lib\urllib2.py", line 389, in open
response = meth(req, response)
File "C:\Programs\Python26\lib\urllib2.py", line 502, in http_response
'http', request, response, code, msg, hdrs)
File "C:\Programs\Python26\lib\urllib2.py", line 421, in error
result = self._call_chain(*args)
File "C:\Programs\Python26\lib\urllib2.py", line 361, in _call_chain
result = func(*args)
File "C:\Programs\Python26\lib\urllib2.py", line 594, in http_error_302
fp.read()
File "C:\Programs\Python26\lib\socket.py", line 327, in read
data = self._sock.recv(rbufsize)
File "C:\Programs\Python26\lib\httplib.py", line 517, in read
return self._read_chunked(amt)
File "C:\Programs\Python26\lib\httplib.py", line 563, in _read_chunked
raise IncompleteRead(value)
httplib.IncompleteRead
With Py3.0 it is the same:
[...]
http.client.IncompleteRead: b''
In this case self.fp.readline() (and the data = recv(1) in socket.py)
returns and the error happens a few lines later.
This seems to happen when there's a redirection in between (the video is
not available in my country, the server sends back a 303 status code,
and redirects me to the home page). The redirection is not handled by
httplib so there might be something wrong in urllib2 too (why it's
trying to read the content if we sent and HEAD request and if there is a
redirection in between?), but fixing httplib to return an empty string
or something similar could be enough to solve this problem too. If
there's actually a problem another issue should probably be created.
With the same code and the url of a working youtube video (no
redirections in between), "page = urllib2.urlopen(req)" works even if
there's the "transfer-encoding: chunked" but it fails later if we do
"page.read()":
Traceback (most recent call last):
File "C:\Programs\Python30\lib\http\client.py", line 520, in _read_chunked
chunk_left = int(line, 16)
ValueError: invalid literal for int() with base 16: ''
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Programs\Python30\lib\http\client.py", line 479, in read

Message-ID: <1245485035.23.0.886110297482.issue6315@psf.upfronthosting.co.za>
New submission from Stephen J. Turnbull <stephen at xemacs.org>:
Which causes the locale machinery to spit exceptions, and the program to
die, usually (eg, hg).
This manifests naturally on an Intel Mac, Mac OS X 10.5.7, but the
problem behavior is in _build_localename. When called as
_build_localename((None,'any_string'))
it returns 'C.any_string'. I don't know of any system that supports
anything but the POSIX portable character set in the C/POSIX locale, so
this is clearly wrong.
I suggest that when the first component of the argument is None, the
second component should be ignored.
Probably my Mac is misconfigured, but I think this is still a bug that
should be fixed.
Observed in all of 2.5.4, 2.6.2, and 3.0.1 (vanilla MacPorts builds).
References: It's possible this is related to issue1699853, issue1176504,
issue504219, but I don't think fixing this will help with those issues.
It is not related to issue3067.

New submission from Steven Bethard <steven.bethard at gmail.com>:
Right now, bdist_msi can run out of memory when used for larger
packages. (I found this problem working with NLTK.) The solution is
really simple - just add a db.Commit() so that stuff gets flushed to
disk more often. The attached patch does just that.
I set this as a release blocker because I think shipping Python 3.1 with
a bdist_msi in that doesn't work for large packages is probably a
mistake, and the patch to fix it is small and non-invasive.

New submission from jwishnie <jwishnie at gmail.com>:
The standard string codecs for converting from unicode to strs does not
include the GSM 0.38 char mapping used by GSM services (like SMS).
I've written a codec for my use based on 'char_mapper' and the skeleton
from gencodec.py, though it's a little complicated by the fact that the
GSM encoding is semi-multibyte and not just a straight table look-up.
Gory details here in the comments:
http://www.unicode.org/Public/MAPPINGS/ETSI/GSM0338.TXT
The codec is available here:
http://github.com/jwishnie/pygsm/tree/f574f6db99c585f785f0c73a080814c043
2c6087/pygsm/gsmcodecs
Please consider it, or an optimized/improved version of it, for
inclusion with the standard codecs distributed with python

New submission from samwyse <samwyse at gmail.com>:
Every time IDLE is asked to run a program, it doesn't ensure that the
modules referenced by the program are completely loaded. This can cause
problems if one of those modules is also being edited, because once it
is loaded, any subsequent changes are not compiled and re-loaded.
PyUnit faced a similar problem and solved it with a custom importer
(http://pyunit.sourceforge.net/notes/reloading.html). Ideally, the
custom importer would be used in two places: The obvious choice is when
a program is run, unloading when it returns. The less obvious is when
the Python Shell window is opened, since import statements can be run
from there as well. Closing that window should cause all such imports
to be unloaded. Of course, care must be taken to insure that all run
commands are properly nested within the lifetime of a shell window.

as "a.py", run "python -m pdb a.py", say "b 3" to set a breakpoint on
line 3. Say "c" to start execution. Watch the program finish without
ever hitting the breakpoint.
The problem is that line 3 has no bytecode generated for it, so there's
nothing to break on. Pdb should provide feedback in this case. I'm the
author of PuDB, and I've written code to check for this condition Please

I was debugging a class where I defined __getitem__ and __iter__, but
not __contains__. The documentation describing this case (at the end of
section 5.9) is old and hasn't been updated for the iterator protocol.
It should read something like:
"For user-defined classes which do not define __contains__() and do
define __iter__() or __getitem__(), x in y is true if and only if there
is a value z reachable from iter(y) before iter(y) throws a
StopIteration exception. (If any other exception is raised, it is as if
in raised that exception)."
Or something better worded.
(I'm using Python 2.5, but I really doubt things have changes in 2.6 or
2.7. I don't know enough about 3.0 to know either way.)

with query strings

Message-ID: <1245731150.83.0.504271486523.issue6325@psf.upfronthosting.co.za>
New submission from Brian Slesinsky <brian at slesinsky.org>:
If a robots.txt file contains a rule of the form:
Disallow: /some/path?name=value
This pattern will never match a URL passed to can_fetch(), as far as I
can tell.
It's arguable whether this is a bug. The 1994 robots.txt protocol is
silent on whether to treat query strings specially and just says "any
URL that starts with this value will not be retrieved". The 1997 draft
standard talks about the path portion of a URL but doesn't give any
examples about how to treat the '?' character in a robots.txt pattern.
Google extends the protocol to allow wildcard characters in a way that
doesn't treat the '?' character specially. See:
http://www.google.com/support/webmasters/bin/answer.py?answer=40360&cbid=-1rdq1gi8f11xx&src=cb&lev=answer#3
I'll leave aside whether to implement pattern matching, but it seems
like a good idea to do something reasonable when a robots.txt pattern
contains a literal '?', and treating it as a literal character seems
simplest.
Cause: in robotparser.can_fetch(), there is this code which seems to
take only the path (stripping the query string).
url = urllib.quote(urlparse.urlparse(urllib.unquote(url))[2]) or "/"
Also, when parsing patterns in the robots.txt file, a '?' character
seems to be automatically URL-escaped. There's nothing in a standards
doc about doing this so I think that might be a bug too.
Tested with python 2.4. I looked at the code in Subversion head and it
doesn't look like there were any changes on the trunk.

New submission from Kristj?n Valur J?nsson <kristjan at ccpgames.com>:
It is sometimes useful to be able to swap the contents of two lists and
this patch provides a way to do so using the fastest way possible.
> a = [1, 2]
> b = [3]
> id(a), id(b)
(100, 101)
> a.swap(b)
> a
[3]
> b
[1, 2]
> id(a), id(b)
(100, 101)
One application of this is to make help a performance problem when one
wants to upgrade a list instance into a subclass instance.
orglist = rawlist_from_server()
mylist = ListSubclass(orglist)
This involves copying duplicating the list, and then discarding, which
can take a while for long lists. Much faster is using>
mylist = ListSubclass()
mulist.swap(orglist)
We are using this extension within CCP to decoratate database queries
from our database engine, that are returned as python lists. The
performance gained by shaving off this extra list duplication can be
significant for large data sets.

Message-ID: <1245782402.41.0.142582030858.issue6329@psf.upfronthosting.co.za>
New submission from Raymond Hettinger <rhettinger at users.sourceforge.net>:
Despite being a sequence (with both __getitem__ and __len__ defined),
memoryview objects were not recognized as being iterable. The docs say
that all such sequences are iterable, so this is a bug.
>>> b = b'abcde'
>>> m = memoryview(b)
>>> list(m)
Traceback (most recent call last):
File "<pyshell#2>", line 1, in <module>
list(m)
TypeError: 'memoryview' object is not iterable
The underlying problem is that the __getitem__ method is listed in the
as_mapping section instead of as_sequence. This was necessary so that
the ellipsis could be supported (the mapping version accepts arbitrary
objects while the sequence version only accepts integer indices).
Unfortunately, the logic for Objects/abstract.c::PySeq_Iter() expects to
find the getitem defined in s->ob_type->tp_as_sequence->sq_item slot.
This patch attaches the appropriate code in that slot. The code is a
simple cut and paste from the more general memory_subscript() function
listed just above.

New submission from Sridhar Ratnakumar <sridharr at activestate.com>:
The logging module has a bug that tries to call `flush' on a closed
file handle (sys.std[out|err] to be specific). This bug was introduced
by ConsoleHandler as defined in http://code.activestate.com/
recipes/576819/
The fix is simple: change definition of StreamHandler.flush in logging/
__init__.py to:
def flush(self):
if self.stream and hasattr(self.stream, 'flush') and not
self.stream.closed:
logging.StreamHandler.flush()

New submission from smartmobili <forumer at smartmobili.com>:
Hi,
I can see that python still doesn't support mingw environnment whil
during past years some people provided some patch.
I wanted recently to compile Python-3.0.1 on mingw and I have found a
patch in a svn repository of a opensource project(don't remember which
one)- So I attach it and I hope it will studied by python dev.
Generally it's not very difficult, you should add some #ifdef
__MINGW32__ when needeed and hack around these lines.
Don't understand you still don't support it.
So this patch is a first step because it doesn't work very well, I mean
I had to copy manually errmap.h from PC to include folder.
And after I get an issue :
gcc -L/usr/local/lib -o python.exe \
Modules/python.o \
libpython3.0.a -lm
Could not find platform independent libraries <prefix>
Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
Fatal Python error: Py_Initialize: can't initialize sys standard streams
ImportError: No module named encodings.utf_8
This application has requested the Runtime to terminate it in an unusual
way.
Please contact the application's support team for more information.

Primarily because the patches that have been contributed don't work
well. We see no point in adding patches that don't work, and prefer
to add only patches that actually do work.

Importing the "uuid" module on a posix system (FreeBSD in my case) that
does not have a C compiler causes "cc: not found" to be sent to stderr.
This is because it imports ctypes and calls ctypes.util.find_library
which attempts to determine if the C compiler is called "gcc" or "cc"
using a shell command.

Message-ID: <1245878670.95.0.838166352982.issue6339@psf.upfronthosting.co.za>
New submission from Gregor Lingl <gregorlingl at users.sourceforge.net>:
In the Python3.1rc2 documentation for turtle.py there are the following
functional errors:
In the overview section the (newly added) entries for the functions/methods
shearfactor
get_shapepoly
onkeypress
numinput
do not have links to the corresponding text sections. These exist but
also have errors, sometimes the leading 'turtle.' is missing, sometimes
the parameter self erroneously appears in the text.
I'm not very educated in restructured Text Syntax respectively the
documentatin system. Nevertheless I inspected the source and I assume
the following causes for this:
In the first lines of the sections for shearfactor and numinput there
are superfluous self, which should be deleted.
In the sections for get_shapepoly, onkeypress and numinput there are
perturbing colons at the end of the first lines, which perhaps should be
deleted.
As I'm not sure if this suggestions are right and/or comlete and I do
not have any means to test them, I cannot submit a patch.
Please could some docs-guru check my suggestions (and possibly repair
the defects) It would be fine if this errors wouldn't appear in 3.1
Regards,
Gregor

Rstrip has unexpected behavior with some strings. Example:
-----
>>> "proxa.py".rstrip(".py")
'proxa'
>>> "proxy.py".rstrip(".py")
'prox'
-----
Tested with Python 2.6.1

My gcc complains that the variables x and y might be used uninitialized

because the macro getsyx of curses.h apparently only sets x and y if
newscr is not NULL. There seems to have been a related discussion last year:

New submission from str1442 <lancerstr at freenet.de>:
After playing around with the setrecursionlimit() Function in the sys
module, i noticed it crashes if you set the limit to a value that is too
high. I explored this further until i noticed the value from which the
crashing begins is exactly 18063. I know that the highest setable value
is platformdependent, but crashing seems inappropriate if a value is
given that is too high.
I'm using Debian GNU/Linux Testing, last upgrade one month ago.
uname -svomr:
Linux 2.6.27.7 #4 SMP Fri Nov 28 01:44:17 CET 2008 i686 GNU/Linux
(Kernel is a pure kernel.org Kernel, self compiled)
Python Version in question is 2.5.4. Searching through the tracker for
setrecursionlimit brought no corresponding issues.
This is a the test script I used:
import sys
sys.setrecursionlimit(18063)
def f():
g()
def g():
f()
f()

In-Reply-To: <1246224690.37.0.731708410356.issue6358@psf.upfronthosting.co.za>
Message-ID: <1246224690.37.0.731708410356.issue6358@psf.upfronthosting.co.za>
New submission from James Abbatiello <abbeyj at gmail.com>:
Start a process with os.popen() and then try to get its exit code by
closing the resulting file handle. The value returned is inconsistent
between 2.x and 3.x. Example:
Python 2.6.2 (r262:71605, Apr 14 2009, 22:40:02) [MSC v.1500 32 bit
(Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> f = os.popen("exit 42", "r")
>>> f.close()
42
Python 3.1 (r31:73574, Jun 26 2009, 20:21:35) [MSC v.1500 32 bit
(Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> f = os.popen("exit 42", "r")
>>> f.close()
10752
>>> divmod(10752, 256)
(42, 0)
The docs for 2.6.2 say that the return value is the exit status of the
process as returned by wait()
(http://docs.python.org/library/os.html#os.popen). That's what 3.1 is
doing(*) but not what 2.6 has actually been doing. In 2.6 the exit code
(not exit status) is returned; if the process didn't exit cleanly then
an exception is thrown.
The docs for 3.1 say that os.popen() is documented in the section "File
Object Creation" but it is not.
http://docs.python.org/3.1/library/os.html#process-management
http://docs.python.org/3.1/library/os.html#file-object-creation
It doesn't seem to be documented at all in 3.1 although it is mentioned
many times on that page.
Since os.popen() is mostly for backward compatibility, should the 3.x
behavior be changed to match the actual 2.6 behavior?
(*) It looks like 3.1 doesn't return the right value if the subprocess
is killed by a signal but I can't test this on win32.

incorrectly for exceptions
In-Reply-To: <1246229003.36.0.107970043042.issue6359@psf.upfronthosting.co.za>
Message-ID: <1246229003.36.0.107970043042.issue6359@psf.upfronthosting.co.za>
New submission from Ned Batchelder <nedbat at users.sourceforge.net>:
Pyexpat.c calls the tracing function explicitly (not sure why). When it
intercepts an exception, it calls the function with PyTrace_EXCEPTION,
but then leaves the scope without calling PyTrace_RETURN. This is
incorrect. There should always be a PyTrace_RETURN for every PyTrace_CALL.
I've attached domshow.py to demonstrate the problem.
Running it produces many lines of output, including:
line expatbuilder.py 222
line expatbuilder.py 223
call pyexpat.c 905
call expatbuilder.py 892
line expatbuilder.py 894
line expatbuilder.py 900
exception expatbuilder.py 900
return expatbuilder.py 900
exception pyexpat.c 905
exception expatbuilder.py 223
line expatbuilder.py 225
line expatbuilder.py 226
The exception at line 905 in pyexpat.c should be followed with a return
from line 905 in pyexpat.c, but is not. After that exception, the
nesting is off by one because the Calls and Returns don't match.

def test(buf):
textio = io.TextIOWrapper(buf)
buf = io.BytesIO()
test(buf)
print(buf.closed) # This prints True currently
The problem here is TextIOWrapper closes its buffer when deleted.
BufferedRWPair behalves similarly. The solution is simply to override
the __del__ method of TextIOWrapper inherited from IOBase.

Subject: [New-bugs-announce] [issue6362] multiprocessing: handling of errno
after signals in sem_acquire()
In-Reply-To: <1246236953.98.0.347685302465.issue6362@psf.upfronthosting.co.za>
Message-ID: <1246236953.98.0.347685302465.issue6362@psf.upfronthosting.co.za>
New submission from Ryan Leslie <rylesny at gmail.com>:
While developing an application, an inconsistency was noted where,
depending on the particular signal handler in use,
multiprocessing.Queue.put() may (or may not) raise OSError() after
sys.exit() was called by the handler. The following example, which was
tested with Python 2.6.1 on Linux, demonstrates this.
#!/usr/bin/env python
import multiprocessing
import signal
import sys
def handleKill(signum, frame):
#sys.stdout.write("Exit requested by signal.\n")
print "Exit requested by signal."
sys.exit(1)
signal.signal(signal.SIGTERM, handleKill)
queue = multiprocessing.Queue(maxsize=1)
queue.put(None)
queue.put(None)
When the script is run, the process will block (as expected) on the
second queue.put(). If (from another terminal) I send the process
SIGTERM, I consistently see:
$ ./q.py
Exit requested by signal.
$
Now, if I modify the above program by commenting out the 'print', and
uncommenting the 'sys.stdout' (a very subtle change), I would expect
the result to be the same when killing the process. Instead, I
consistently see:
$ ./q.py
Exit requested by signal.
Traceback (most recent call last):
File "./q.py", line 15, in <module>
queue.put(None)
File "python2.6/multiprocessing/queues.py", line 75, in put
if not self._sem.acquire(block, timeout):
OSError: [Errno 0] Error
$
After debugging this further, the issue appears to be in
semlock_acquire() or semaphore.c in Modules/_multiprocessing:
http://svn.python.org/view/python/trunk/Modules/_multiprocessing/semaphore.c?revision=71009&view=markup
The relevant code from (the Unix version of) semlock_acquire() is:
do {
Py_BEGIN_ALLOW_THREADS
if (blocking && timeout_obj == Py_None)
res = sem_wait(self->handle);
else if (!blocking)
res = sem_trywait(self->handle);
else
res = sem_timedwait(self->handle, &deadline);
Py_END_ALLOW_THREADS
if (res == MP_EXCEPTION_HAS_BEEN_SET)
break;
} while (res < 0 && errno == EINTR && !PyErr_CheckSignals());
if (res < 0) {
if (errno == EAGAIN || errno == ETIMEDOUT)
Py_RETURN_FALSE;
else if (errno == EINTR)
return NULL;
else
return PyErr_SetFromErrno(PyExc_OSError);
}
In both versions of the program (print vs. sys.stdout), sem_wait() is
being interrupted and is returning -1 with errno set to EINTR. This is
what I expected. Also, in both cases it seems that the loop is
(correctly) terminating with PyErr_CheckSignals() returning non-zero.
This makes sense too; the call is executing our signal handler, and then
returning -1 since our particular handler raises SystemExit.
However, I suspect that depending on the exact code executed
for the signal handler, errno may or may not wind up being reset in
some nested call of PyErr_CheckSignals(). I believe that the
error checking code below the do-while (where sem_wait() is called),
needed errno to have the value set by sem_wait(), and the author
wasn't expecting anything else to have changed it. In the "print"
version, errno apparently winds up unchanged with EINTR, resulting in
the `return NULL' statement. In the "sys.stdout" version (and probably
many others), errno winds up being reset to 0, and the error handling
results in the `return PyErr_SetFromErrno(PyExc_OSError)' statement.
To patch this up, we can probably just save errno as, say, `wait_errno'
at the end of the loop body, and then use it within the error handling
block that follows. However, the rest of the code should probably be
checked for this type of issue.

New submission from Stefan Behnel <scoder at users.sourceforge.net>:
When compiling a C extension (lxml in this case) in Py3.1, calling the
"build_ext -i" distutils target duplicates the package path when writing
the dynlib. In this case, I get "lxml/lxml/etree.so" instead of
"lxml/etree.so". Obviously, the extension module cannot be found
afterwards, as it's not inside its package anymore. The extension is
named "lxml.etree" when creating the Extension object.
This is a regression from 3.1rc1 AFAICT.

HI all
I am not the too technical guy, but thinking about the new way of
controlling the flow instead of throwing an error.
as of now if we need to break a control and go back exceptions helps,
but it is not a actual way.
it would be great if we have a control over the frames execution, I mean
A calls B calls C calls D
at that point if we think to move directly to B (what error handler do
if that B has the handler defined of the error), changing the frames
instruction pointer to back to the B's position (in python code without
raising an exception) is a really useful for this web applications.
Please excuse me if we have this control already, (can u explain?)
Thanks
Vinoth

New submission from SilentGhost <michael.mischurow+bpo at gmail.com>:
I'm comparing initialisation of Counter from an iterable with the
following function:
def unique(seq):
"""Dict of unique values (keys) & their counts in original sequence"""
out_dict = dict.fromkeys(set(seq), 0)
for i in seq:
out_dict[i] += 1
return out_dict
iterable = list(range(43)) + list(range(43, 0, -1))
The timeit-obtained values show that it takes Counter four (4) times
longer to finish. As it's obvious from comparing my function and lines
429-430 of collections.py the only difference is preallocating the final
dictionary. When line 430 of collections is replaced with:
self[elem] = self.get(elem, 0) + 1
I was able to get about 25% time-performance increase (I assume
__missing__ is bypassed). I hope that it's possible to improve its
implementation even further.

New submission from Pablo Torres Navarrete <tn.pablo at gmail.com>:
I propose that all formal parameters that really act as options/switches
be made keyword-only. Examples of switches are all flags, timeouts,
'verbose' bools, maximums and minimums, etc.
This stresses the difference between needed input for a function and an
argument that changes/extends the behavior. Besides, the code would be
more readable, because instead of having some cryptic function call like
register('Pablo Torres', 2, 4, 5, False) you would have the prettier
register('Pablo Torres', hour=2, min=4, sec=5, had_reservation=False).
The implementation would just require putting a star '*' before all
options, according to pep 3102.
If needed, I can rewrite this as a PEP.

New submission from Pascal Chambon <chambon.pascal at gmail.com>:
I feel the description of the subprocess.popen semantics is a little
incomplete/confusing to me, on some points, eg. :
- what does the "shell" argument do on windows, exactly ? The beginning
of the description states that nothing changes (createProcess() is used
in any way), but later "COMSPEC" and "shell" are quoted, and their
effect is unclear on windows...
-"If cwd is not None, the child?s current directory will be changed to
cwd before it is executed. Note that this directory is not considered
when searching the executable, so you can?t specify the program?s path
relative to cwd." -> maybe we should precise that only the "executable"
argument is concerned, not the 'executable' program name which might be
given as first item in "args" argument (and which is, on the contrary,
searched relatively to "cwd" argument)
-for the "bufsize" argument, it would be handy to precise which buffer
size is set (of which file descriptors exactly ? Of Pipes only ?)
Regards,
P. Chambon

The library reference of Decimal.logical_invert:
.. method:: logical_invert(other[, context])
:meth:`logical_invert` is a logical operation. The argument must
be a *logical operand* (see :ref:`logical_operands_label`). The
result is the digit-wise inversion of the operand.
There should not be "other" argument, since it's an unary operation.

With the release of Python 3.1 the --compiler switch is ignored in

Once that was fixed there was another issue with get_version() in
cygwincompiler but that appears to be fixed in the 3.1 branch. The
revision that introduced this problem is 72596 (from 72593 in trunk).

New submission from Zbigniew Braniecki <zbigniew.braniecki at gmail.com>:
Python has a very useful function any() that will iterate over a list
and break on the first matching case.
Now, it would be great to have similar function but with:
a) ability to use a callback for matching test
b) that would return the first match
so something like:
key = first(['es-AR','es','en-US'], lambda x:self._value.has_key(x))
instead of:
for k in ['es-AR','es','en-US']:
if self._value.has_key(k):
key = k
break
It would be also nice to be able to capture the first match and return it:
value = first(['es-AR','es','en-US'], lambda x:self._value[x])
I'm not sure which one is more generically applicable.

Subject: [New-bugs-announce] [issue6380] Deadlock during the "import" in the
fork()'ed child process if fork() happened while import_lock
was held
In-Reply-To: <1246315934.51.0.706424064381.issue6380@psf.upfronthosting.co.za>
Message-ID: <1246315934.51.0.706424064381.issue6380@psf.upfronthosting.co.za>
New submission from Dmitriy Khramtsov <highdn at gmail.com>:
Greetings,
The 2.4 and 2.5 versions of python contains a deadlock caused by
possibility to hold import_lock while doing fork() and not resetting it
in the child (on the linux platform).
The prove of concept code is:
--BEGIN (import_lock.py)--
#!/usr/bin/python2.4
import os
import time
import threading
class SecondThread(threading.Thread):
def run(self):
# Give the main thread time to hold import_lock and start importing.
time.sleep(1)
# Fork the process while holding import_lock in the main thread.
pid = os.fork()
if pid == 0: # Child process
print "child begin"
# The import lock is still taken by main thread which is now not
the part
# of the child process. The import lock will never be released in the
# child process. Effectively, any import is a deadlock from now on.
import types
# This statement will never be executed.
print "child end"
def main():
second_thread = SecondThread()
second_thread.start()
# Take the import_lock and then release global interpreter lock in the
# import_lock_helper module by calling any blocking operation.
import import_lock_helper
second_thread.join()
main()
--END (import_lock.py)--
--BEGIN (import_lock_helper.py)--
#!/usr/bin/python2.4
import time
# Release the global interpreter lock by calling any blocking operation.
time.sleep(10)
--END (import_lock_helper.py)--
The stack of the child python interpreter at the time of dead lock:

(gdb) pystack
import_lock.py (26): run
/usr/lib/python2.4/threading.py (443): __bootstrap
The code directly responsible for import locking (Python/import.c):
--BEGIN--
static PyThread_type_lock import_lock = 0;
static long import_lock_thread = -1;
static int import_lock_level = 0;
static void
lock_import(void)
{
long me = PyThread_get_thread_ident();
if (me == -1)
return; /* Too bad */
if (import_lock == NULL) {
import_lock = PyThread_allocate_lock();
if (import_lock == NULL)
return; /* Nothing much we can do. */
}
if (import_lock_thread == me) {
import_lock_level++;
return;
}
if (import_lock_thread != -1 ||
!PyThread_acquire_lock(import_lock, 0))
{
PyThreadState *tstate = PyEval_SaveThread();
PyThread_acquire_lock(import_lock, 1);
PyEval_RestoreThread(tstate);
}
import_lock_thread = me;
import_lock_level = 1;
}
static int
unlock_import(void)
{
long me = PyThread_get_thread_ident();
if (me == -1 || import_lock == NULL)
return 0; /* Too bad */
if (import_lock_thread != me)
return -1;
import_lock_level--;
if (import_lock_level == 0) {
import_lock_thread = -1;
PyThread_release_lock(import_lock);
}
return 1;
}
/* This function is called from PyOS_AfterFork to ensure that newly
created child processes do not share locks with the parent. */
void
_PyImport_ReInitLock(void)
{
#ifdef _AIX
if (import_lock != NULL)
import_lock = PyThread_allocate_lock();
#endif
}
--END--
The possible solution is to reset import_lock in the
_PyImport_ReInitLock() not only for _AIX but also for Linux and maybe
other platforms (do you know why _AIX-only guard is there?).
--CUT HERE--
void
_PyImport_ReInitLock(void)
{
if (import_lock != NULL)
import_lock = PyThread_allocate_lock();
}
--CUT HERE--
Prove of concept example above works fine (w/o deadlocks) on the python
interpreter rebuilt with the _PyImport_ReInitLock() modification above.
Also this bug can be worked around in Python code by holding import_lock
before fork() and releasing import_lock right after fork() in both
parent and child.
The workaround code is:
--BEGIN (workaround_fork_import_bug.py)--
import imp
import os
def __fork():
imp.acquire_lock()
try:
return _os_fork()
finally:
imp.release_lock()
try:
_os_fork
except NameError:
_os_fork = os.fork
os.fork = __fork
--END (workaround_fork_import_bug.py)--
This workaround can also be implemented in Python interpreter in C and
could be other solution for this bug.
Thanks,
Dmitriy

I am making a demo program, a class which is a subset of int, which
implements a partial implementation of PEP313 (Roman numeral literals).
I discover that my conversion routines fail for values > 50000 due to an
error in unicodedata for the two code points 2187 and 2188. The return
value of unicodedata.numeric() for those two points should be 50,000.0

when initial script is a symbolic link

Message-ID: <1246356344.6.0.218965497612.issue6386@psf.upfronthosting.co.za>
New submission from jbeulich <jbeulich at novell.com>:
Due to the way PySys_SetArgv() works, when the initial script is a
symbolic link, importing from normal files in the same directory does
not work. This is particularly surprising when the work tree is a
symlinked clone (cp -s) of an original (i.e. snapshot) tree with a few
modifications (patches) applied to one or more of the modules imported
from: Due the the erratum, the modifications made will appear to not
take effect until one realizes that the wrong module is being imported from.
The solution would in my opinion be to not only add the path left after
the readlink()/realpath() processing to the import search path list, but
also any intermediately encountered ones (in the order processed) as
long as the leaf component continues to be a symlink.
(Note: It seems pointless to use readlink() in the current [3.1 and
earlier] implementation, since the result gets passed to realpath()
anyway. Also, the documentation doesn't seem to mention this behavior,
and from the sources it remains unclear why this processing is needed at
all.)

New submission from David Jones <drj at pobox.com>:
Consider: x//y != x//float(y) for some integer values of x and y.
For example, x = 2**54-1, and y = 2:
>>> x=2**54-1
>>> y=2
>>> x//y
9007199254740991L
>>> x//float(y)
9007199254740992.0
>>> _==x//y
False
I have no idea whether this should actually be a bug or not. The
behaviour (above) _is_ the documented behaviour (because the operands
are documented as being converted to a common type). But... I think
there's a good case for computing the mathematically correct answer
regardless of the types of the inputs. For one thing, one of the
reasons behind introducing the // operator was to make division the same
regardless of whether the inputs were floating point or int. Computing
the mathematically correct answer (which since the answer is an integer
is always exactly representable in Python) would be better, and simpler
to document.

New submission from Michael <mhearne808 at yahoo.com>:
If you look at the documentation for os.chmod(), it says:
"mode may take one of the following values (as defined in the stat
module)..."
and then lists a number of constants from the stat module (stat.S_ISUID,
stat.S_ISGID, etc.)
I cannot seem to find these constants defined anywhere on the stat
module page. May I suggest that these constants be defined in the
documentation for os.chmod(), to make it easier on the user?

Subject: [New-bugs-announce] [issue6390] File reads past EOF in "w+b" mode

Message-ID: <1246380770.16.0.615703374982.issue6390@psf.upfronthosting.co.za>
New submission from Brian Mearns <bmearns at ieee.org>:
Open a file in "w+b" mode: if you write to the file, then read from it
without seeking backward, it reads past the EOF, apparently out into
memory, which could be a pretty bad security concern. Have not checked
if "w+" mode does the same.
### Bad behavior...
>>> fid = open("temp", "w+b")
>>> fid.read()
''
>>> fid.write("foobar")
#Read while positioned on EOF
>>> fid.read(10)
'\xc2\x00\x00\x00\x00\x00\x00\x00\x00\x00'
>>> fid.seek(0)
>>> fid.read(10)
'foobar\xc2\x00\x00\x00'
>>> fid.close()
###Correct behavior after seeking backwards:
>>> fid = open("temp2", "w+b")
>>> fid.read()
''
>>> fid.write("foobar")
>>> fid.seek(0)
>>> fid.read(10)
'foobar'
>>> fid.close()
Interestingly, it appears that any seek works, you don't necessarily
have to go backwards:
>>> fid = open("temp2", "w+b")
>>> fid.write("foobar")
>>> fid.tell()
6L
>>> fid.seek(6)
>>> fid.read()
''

In Python 2.6 Document, Library reference 26.3 unittest
(http://docs.python.org/library/unittest.html#unittest.TestCase.run)
The description of TestCase.run method says that ``If result is omitted
or None, a temporary result object is created (by calling the
defaultTestCase() method) and used'', but I think it should be
defaultTestResult() instead of defaultTestCase().
