[issue3448] Multi-process 2to3

[Collin Winter]

Collin Winter <[EMAIL PROTECTED]> added the comment:

"I don't think we should force people using it as a library to go
multiprocess."

I don't understand this. What downsides do you perceive in
multiprocessing support? Multiprocessing is a significant speed-up for
2to3 on multicore systems.

[issue4013] Python 2.6 Doc/tools folder bigger than in 2.6rc2

[Koen van de Sande]

New submission from Koen van de Sande <[EMAIL PROTECTED]>:

The Doc/tools folder in the 2.6 distribution contains docutils, jinja, 
pygments, sphinx folders, which were not there in the 2.6rc2 .tar.bz2. 
Also, there is a roman.pyc in the Doc/tools folder. 

The difference in uncompressed size is about 9MB between 2.6 and 
2.6rc2. The difference in compressed size is 1.5MB. Perhaps including a 
fully functional doc build environment is intentional?

[issue957650] Fix for bugs relating to ntpath.expanduser()

[Christian Heimes]

Christian Heimes <[EMAIL PROTECTED]> added the comment:

I just saw this bug entry in the whatsnew list. The os.path.expanduser()
function handles ~user the wrong way. The (naive) implementation expects
that all user directories are inside a common base path. This is only
true for standalone Windows computers.

There is no way to get the path to a user's home directory w/o her
login+password or the login of a domain admin. The feature should be
removed in 2.6.1.

Martin, do you concur?

[issue4006] os.getenv silently discards env variables with non-UTF-8 values

[Toshio Kuratomi]

Toshio Kuratomi <[EMAIL PROTECTED]> added the comment:

It's not a feature it's a bug! :-)  (I hope you meant to have a smiley
too ;-)

As stated in the os.listdir() related bug, on Unix filesystems filenames
are a sequence of bytes.  The system encoding allows the user-level
tools to display the filenames as characters instead of byte sequences
and allows you to manipulate the filenames using characters instead of
byte sequences.  But if you change your locale the user level tools will
interpret the byte sequences as different characters and allow you free
access to create files in a different encoding.

So in order to work correctly on Unix you must be able to accept byte
sequences in place of filename.

The sad fact of the matter is that while we can be all unicode with data
and strings inside of python we will always have to be prepared to
handle supposed strings as byte sequences when talking to some things
outside of ourselves.  Sometimes the border has a specification that
tells us what encoding to expect and we can do conversion automatically.
 But when it doesn't we have to be prepared to 1) tell the user that the
data exists even but isn't string type as expected and 2) make the byte
sequence available to the user.

Silently pretending that the data doesn't exist at all is a bug (maybe a
minor bug depending on how often we expect the situation to arise but
still a bug.)

[issue1541] Bad OOB data management when using asyncore with select.poll()

[Josiah Carlson]

Josiah Carlson <[EMAIL PROTECTED]> added the comment:

While handle_expt() is documented has only being called when OOB data is 
known, it has become the catch-all for "something strange is happening 
on the socket".

The reason it wasn't changed/fixed in Python 2.6 is because a new method 
would need to be added, which would break previously existing asyncore-
derived applications.

I might still be able to fix it for 3.0 .

Martin, can you check in your changes to add sys.setfilesystemencoding()?

I will check in Victor's changes (with some edits).

Together this means that the various suggested higher-level solutions
(like returning path-like objects, or some kind of roudtripping
almost-but-not-quite-utf-8 encoding) can be implemented in pure Python.

Barry:
I've marked this bug as blocker because it makes Vista installations
useless. It's not a blocker for the upcoming beta but it should be fixed
before the next rc. It's a rather nasty issue with side-by-side
assemblies. It can only be debugged on a Vista machine *WITHOUT* any
development tools like Visual Studio or 3rd party programs shipped with
msvcrt90 assembly.

Georg Brandl <[EMAIL PROTECTED]> added the comment:

There's also an applyAsync left in the introductory Pool example.

Jesse, while you're at it, could you please add a blurb that some
examples won't work when tried at the interactive interpreter (and
perhaps also why)?

[issue4012] Minor errors in multiprocessing docs

[Georg Brandl]

Georg Brandl <[EMAIL PROTECTED]> added the comment:

I e.g. tried a minimal example with Pool.map():

>>> from multiprocessing import Pool
>>> p = Pool(5)
>>> def f(x):
...  return x*x
...
>>> p.map(f, [1,2,3])
Process PoolWorker-1:
Traceback (most recent call last):
  File "/home/gbr/devel/python/Lib/multiprocessing/process.py", line
231, in _bootstrap

in run
self._target(*self._args, **self._kwargs)
  File "/home/gbr/devel/python/Lib/multiprocessing/pool.py", line 57, in

Process PoolWorker-2:

[some more exceptions]

task = get()
  File "/home/gbr/devel/python/Lib/multiprocessing/queues.py", line 339,

And then the prompt doesn't reappear.

[issue2810] _winreg.EnumValue fails when the registry data includes multibyte unicode characters

[Erik Nolte]

Erik Nolte <[EMAIL PROTECTED]> added the comment:

To reproduce on Windows XP with Python 2.4, 2.5, and 2.6:

1. Import issue_2810.reg (it creates two keys under
HKCU\PythonTestUnicodeKeys: one with a one byte unicode char in the key,
the other with multiple 2-byte unicode chars)

2. Run the following:
import _winreg

key = _winreg.OpenKey( _winreg.HKEY_CURRENT_USER, "PythonTestUnicodeKeys" )

one_byte_key = _winreg.EnumKey( key, 0 )
two_byte_key = _winreg.EnumKey( key, 1 )

_winreg.CloseKey( key )

try:
unicode( one_byte_key )
except Exception, ex:
print "EnumKey didn't return a valid string:", ex

print "should be unicode, not str:", two_byte_key.__class__
for ch in two_byte_key:
print ord( ch ),
print ""

I'll add a note. I'm going to file a separate bug, I don't think that

This is useful but as its a feature we won't be able to add it until

Until then, the approach I suggest is to subclass httplib.HTTPConnection

[issue4020] hasattr boundary case failure

[Xore]

New submission from Xore <[EMAIL PROTECTED]>:

http://www.python.org/doc/2.5.2/lib/built-in-funcs.html#l2h-35

"(This is implemented by calling getattr(object, name) and seeing
whether it raises an exception or not.)"

If a property exists but it's retrieval throws some error, hasattr will
interpret this as the property not existing, since it only checks for
the existence of an error, not an AttributeError


class test:
@property
def prop(self):
# do stuff
raise ZeroDivisionError # an example

foobar = test()

assert hasattr(foobar, "prop")

[issue957650] Fix for bugs relating to ntpath.expanduser()

[Martin v. Löwis]

Martin v. Löwis <[EMAIL PROTECTED]> added the comment:

> Martin, do you concur?

Not really. On my system, which is part of a domain, expanduser("~")
gives 'C:\\Documents and Settings\\martin.vonloewis', which is
indeed the directory where my profile lives. HOMEDRIVE is Y:,
and HOMESHARE is some system in our network, but those aren't
considered for determining ~ - although I do think
%HOMEDRIVE%\%HOMEPATH% might have been a better choice.
However, given the choice that was made, I think the assumption
is correct that somebody else's profile will live in the same
folder. Is it possible to configure a domain profile so that it's
not in Documents and Settings?

Even if this doesn't work for all systems, I don't think we can
revert it for 2.6.1 (as it does give the correct answer at least
in some cases). Such a change will have to wait for 2.7.

[issue4018] "for me" installer problem on x64 Vista

[Martin v. Löwis]

Martin v. Löwis <[EMAIL PROTECTED]> added the comment:

I had noticed the problem myself, and I don't know any solution to it.
It's still part of the aftermath of switching to VS 2008, maybe we
should have stayed with VS 2003 :-(

Out of curiosity: Is this Vista SP1? If so, can somebody try Vista RTM?
I recall that it used to work, but I don't have any Vista RTM
installation anymore.

In short, the problem is that Vista now complains about the .. in the
name attribute of the manifest; XP considers the manifest file fine.

A work-around is to place another copy of msvcr90.dll into the DLLs
order, and adjusting the manifest to point to this copy. I rejected this
solution, as it causes two copies of the CRT to be loaded (as can be
seen in sysinternals process explorer). Loading two copies of the CRT
itself caused problems in the past (e.g. when FILE* is passed across DLL
boundaries).

As a consequence, I propose that the "for me" installation just isn't
supported on Vista; it should be easy to adjust the UI accordingly.
Vista users should invoke the "for all installation" (and I should
change the installer back to invoking UAC).

In any case, I don't think this should block the release, given that no
real solution seems possible.

[issue4010] configure options don't trickle down to distutils

[Roumen Petrov]

Roumen Petrov <[EMAIL PROTECTED]> added the comment:

One of the problems that I see in that LDFLAGS is Makefile variable and
Makefile is part of distribution for posix build systems.
If you set specific LDFLAGS and you want to distribute own python build
user will get you specific settings.
One another environment variable is OPT (if compiler don't accept -R XXX
may be -Wl,-rpath,XXX ?) and we may use it. Also OPT environment
variable is also Makefile variable and user specific settings will go
into distribution too :( .

I quick look into distutils code show that sysconfig.py don't parse
LDFLAGS and append environment variable LDFLAGS as is to the ldshared
variable.
So the first question is why setup.py parse only -L flags instead to
pass variable value as is (aka sysconfig.py).
The second question is why LDFLAGS is a Makefile variable ? 


For now I would like to know if you set on Solaris suitable
LD_RUN_PATH(for the build) and LD_LIBRARY_PATH (when run) did you
succeed to build and run python ?

[issue4018] "for me" installer problem on x64 Vista

[John Ehresman]

John Ehresman <[EMAIL PROTECTED]> added the comment:

I think one of the tested machines is Vista RTM, though it's been 
updated.  I also tried of Vista x32 SP1 and it fails there.

If non-admin installs can't be made to work, I agree that the "for me" 
option be dropped and the installer changed to invoke UAC.  I looked for 
a solution to this, but so far can't find any -- and this would also 
mean that .pyd files in site-packages and elsewhere would need .manifest 
files that contain the path to where msvcr90.dll is located.  I think 
requiring an admin install might cause problems for py2exe though.

This is rather important because it means that python is unusable using 
the default installation options and I suspect that many users won't 
know how to install for everyone.

I'd still like to see the need to depend on a C runtime dll dropped at 
some point in the future, but I know that it's not an easy thing to do.

[issue4008] IDLE: checksyntax() doesn't support Unicode?

[STINNER Victor]

STINNER Victor <[EMAIL PROTECTED]> added the comment:

loewis wrote:
> Notice that there is also IOBinding.coding_spec.
> Not sure whether this or the one in tokenize is more correct.

Oh! IOBinding reimplement many features now available in Python like 
universal new line or function to write unicode strings to a file. But 
I don't want to rewrite IDLE, I just want to fix the initial problem: 
IDLE is unable to open a non-ASCII file using "#coding:" header.

So IDLE reimplemented coding detection twice: once in IOBinding and 
once in ScriptBinding. So I wrote a new version of my patch removing 
all the code to reuse tokenize.detect_encoding().

I changed IDLE behaviour: IOBinding._decode() used the locale encoding 
if it's unable to detect the encoding using UTF-8 BOM and/or if the 
#coding: header is missing. Since I also read "Finally, try the 
locale's encoding. This is deprecated", I prefer to remove it. If you 
want to keep the current behaviour, use:
-
def detect_encoding(filename, default=None):
with open(filename, 'rb') as f:
encoding, line = tokenize.detect_encoding(f.readline)
if (not line) and default:
return default
return encoding
...
encoding = detect_encoding(filename, locale_encoding)
-

Please review and test my patch (which becomes longer and longer) :-)

@a.badger: Again, dropping invalid filenames in listdir() is a (very

See also issue3187 and read the long python-dev mailing list thread 
about filenames (start few days ago).

Guido just commited my huge patch to support bytes filename in Python3 
trunk. So using Python3 final, you will be abl to list all files using 
os.listdir(b'.') or os.listdir(os.getcwdb()).

Because that's the use case I was supporting when I added the support;
I just needed the -L flags for compiling the extensions. If someone
writes a patch that makes it more generic it has a chance of being
checked in.

> The second question is why LDFLAGS is a Makefile variable ?

Because there is no guarantee that someone specified the envvar when
running setup.py, but if they were set for configure you know that
Python was built using those values.

I don't think this could even work: apparently, Vista disallows putting
a path into the name field. So extension modules will have to ship with
their own copy of the CRT (or link statically).

[issue4008] IDLE: checksyntax() doesn't support Unicode?

[Martin v. Löwis]

Martin v. Löwis <[EMAIL PROTECTED]> added the comment:

> Oh! IOBinding reimplement many features now available in Python like 
> universal new line or function to write unicode strings to a file.

It did not *re*implement. The implementation in IOBinding predates all
other implementations out there.

[issue2636] Regexp 2.7 (modifications to current re 2.2.2)

[Matthew Barnett]

Matthew Barnett <[EMAIL PROTECTED]> added the comment:

Perl v5.10 offers the ability to have duplicate capture group numbers in
branches. For example:

(?|(a)|(b))

would number both of the capture groups as group 1.

Something to include?

[issue2636] Regexp 2.7 (modifications to current re 2.2.2)

[Matthew Barnett]

Matthew Barnett <[EMAIL PROTECTED]> added the comment:

I've extended the group referencing. It now has:

Forward group references

(\2two|(one))+

\g-type group references

(n is name or number)
\g (Python re replacement string)
\g{n} (Perl)
\g'n' (Perl)
\g"n" (because ' and " are interchangeable)
\gn   (n is single digit) (Perl)

(n is number)
\g<+n>
\g<-n>
\g{+n} (Perl)
\g{-n} (Perl)

\k-type group references

(n is group name)
\k (Perl)
\k{n} (Perl)
\k'n' (Perl)
\k"n" (because ' and " are interchangeable)

[issue4021] tokenize.detect_encoding(): raise SyntaxError on codecs.lookup() error

[STINNER Victor]

New submission from STINNER Victor <[EMAIL PROTECTED]>:

tokenize.detect_encoding() raises a LookupError() if the charset is 
unknown whereas Python raises a SyntaxError. So this patch mimics 
Python behaviour for tokenize module.

Extra: reuse BOM_UTF8 from the codecs module.

[issue4008] IDLE: checksyntax() doesn't support Unicode?

[STINNER Victor]

STINNER Victor <[EMAIL PROTECTED]> added the comment:

@loewis: Ok, I didn't know. I think that it's better to reuse existing 
code.

I also compared the implementations of encoding detection, and the 
code looks the same in IDLE and tokenize, but I prefer tokenize. 
tokenize.detect_encoding() has longer documentation, return the line 
(decoded as Unicode) matching the encoding cookie, and look to be more 
robust.

I saw an interesting test in IDLE code: it checks the charset. So I 
wrote a patch raising a SyntaxError for tokenize: issue4021.

[issue4018] "for me" installer problem on x64 Vista

[John Ehresman]

John Ehresman <[EMAIL PROTECTED]> added the comment:

> I don't think this could even work: apparently, Vista disallows putting

I agree that this is the case.  The closest thing I found to 
documentation of this is 
http://msdn.microsoft.com/en-us/library/ms235291.aspx under Deploying 
Visual C++ library DLLs as private assemblies.  It specifies that the 
assembly be copied twice, once into the folder with the .exe and again 
into the folder with the .dll.

I think the best option is to always install for everyone as 
administrator on Vista.

[issue4022] 2.6 dependent on c:\python26\ on windows

[Armando Rowe]

New submission from Armando Rowe <[EMAIL PROTECTED]>:

The windows installer for Python 2.6 offers to install on c:\python26\ -
If you chose to install on c:\python\ instead, the installation will run
through and terminate succesfully, but whenever you try executing any
python program, an error message tells you that mvscr90.dll is missing.

It turns out the installer does properly install the dll in a subfolder
of c:\windows\winsxs.

If you remove python, then install on c:\python26\, it will work just fine.

Event occurred on a Dell latitude D620 laptop with 2 GB RAM and a 2 GHz
intel core duo, with Windows XP professional Service Pack 3. No python
packages were installed.

I can't reproduce the problem. It works fine for me, displaying the box

[issue4023] convert os.getcwdu() to os.getcwd(), and getcwdu() to getcwd()

[STINNER Victor]

New submission from STINNER Victor <[EMAIL PROTECTED]>:

Python3 removes os.getcwdu() and introduces os.getcwdb(). The patch is 
a fixer for lib2to3 replacing "os.getcwdu()" to "os.getcwd()", 
and "getcwdu()" to "getcwd()". I hope that nobody defined its 
own "getcwdu()" function :-)

Example:

cwd = os.getcwdu()
print "cwd=%s" % cwd

from os import getcwdu
cwd = getcwdu()
print "cwd=%s" % cwd


Result:
-
 import os
-cwd = os.getcwdu()
-print "cwd=%s" % cwd
+cwd = os.getcwd()
+print("cwd=%s" % cwd)

-from os import getcwdu
-cwd = getcwdu()
-print "cwd=%s" % cwd
+from os import getcwd
+cwd = getcwd()
+print("cwd=%s" % cwd)

[Martin v. Löwis]

Martin v. Löwis <[EMAIL PROTECTED]> added the comment:

(there is currently no patch attached)

I don't think getcwd() should be fixed as getcwdb(). It's not possible
to tell what the intention of the call was, in which case I recommend
not to change the code at all.
