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

[Toshio Kuratomi]

New submission from Toshio Kuratomi <[EMAIL PROTECTED]>:

On a Linux system with a locale setting whose encoding is utf-8, if you
set an environment variable to have a non-utf-8 chanacter, that
environment variable silently does not appear in os.environ::

mkdir ñ
convmv -f utf-8 -t latin-1 --notest ñ
for i in * ; do export PATH=$PATH:$i ; done
echo $PATH
/usr/lib/qt-3.3/bin:/usr/kerberos/bin:/usr/lib/ccache:/usr/local/bin:/usr/bin:/bin:/home/badger/bin:�
python3.0
Python 3.0rc1 (r30rc1:66499, Sep 28 2008, 08:21:09) 
[GCC 4.3.0 20080428 (Red Hat 4.3.0-8)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> os.environ['PATH']
Traceback (most recent call last):
  File "", line 1, in 
  File "/usr/lib/python3.0/os.py", line 389, in __getitem__
return self.data[self.keymap(key)]
KeyError: 'PATH'

I'm uncertain of the impact of this.  It was brought up in a discussion
of sending non-ASCii data to a CGI-WSGI script where the data would be
transferred via os.environ.

[issue2382] [Py3k] SyntaxError cursor shifted if multibyte character is in line.

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc <[EMAIL PROTECTED]> added the comment:

For the moment, I'd suggest that one unicode character has a the same
with as the space character, assuming that stdout.encoding correctly
matches the terminal.

Then the C implementation could do something similar to the statements I
added in traceback.py:
offset = len(line.encode('utf-8')[:offset].decode('utf-8'))

[issue3448] Multi-process 2to3

[Collin Winter]

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

I believe the only issue I recall was that the patch didn't work
out-of-the-box for Python 2.6 (changed imports, PEP 8 compliance changes
in the multiprocess module). Has that been fixed?

I disagree with Benjamin: this is an import speed increase, and I don't
see the point in adding the needless complexity of a subclass. The user
won't notice any difference, and anyone wanting to use this as a library
will want the faster version.

The "clean" target in the makefile fails to delete the libpython.a file
and the libpython.so.X.Y file (should you have configured using
--enable-shared).  The attached trivial patch solves that problem.
The patch is against the trunk as of just before the 2.6 final release.
It will almost certainly apply cleanly to the py3k version as well.

class C(object):
def __init__(self): self._x = None


All other lines in the code example are written in the way that the 
code block of the function definition is in the next line and properly

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

[STINNER Victor]

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

Hum, the problem is that IDLE asks io.open() to detect the charset 
whereas open() doesn't know the #coding: header. So if your locale is 
ASCII, CP1252 or anything different of UTF-8, read the file will 
fails.

I wrote a patch to detect the encoding. Python code (detect_encoding() 
function) is based on PyTokenizer_FindEncoding() and get_coding_spec() 
(from Parser/tokenizer.c). There is no existing Python function to 
detect the encoding of a Python script? (a public function available 
in a Python script)

The current version is clear and maintainable.  There is nothing unholy

feature for named tuples that they are exactly equivalent to a
hand-written class.

I appreciate your effort but am rejecting it flat-out.

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

[Skip Montanaro]

New submission from Skip Montanaro <[EMAIL PROTECTED]>:

If you are fortunate enough to have all your third-party libraries in
a single quasi-standard location, say, /usr/local/lib, you will
probably have never encountered this problem, but setting environment
variables like LDFLAGS don't get translated into the relevant args for
the distutils build_ext command.  The evidence for this is this output
at the end of the make process:

Failed to find the necessary bits to build these modules:
_hashlib   _sqlite3   _ssl
bsddb185   linuxaudiodev  ossaudiodev
To find the necessary bits, look in setup.py in detect_modules() for
the module's name.


Failed to build these modules:
_curses_curses_panel  _tkinter
gdbm   readline

Here's the specific failure for readline:

>>> import readline_failed
Traceback (most recent call last):
  File "", line 1, in 
ImportError: ld.so.1: python: fatal: libreadline.so.4: open failed: No
such file or directory

yet if you poke around in my config.status file you'll see that I set
the relevant -L and -R flags:

s,@LDFLAGS@,|#_!!_#|-L/opt/app/nonc++/ncurses-5.6/lib
-R/opt/app/nonc++/ncurses-5.6/lib -L/opt/app/nonc++/gdbm-1.8/lib
-R/opt/app/nonc++/gdbm-1.8/lib -L/opt/app/nonc++/readline-4.3/lib
-R/opt/app/nonc++/readline-4.3/lib -L/opt/app/nonc++/tcl-8.4/lib
-R/opt/app/nonc++/tcl-8.4/lib -L/opt/app/nonc++/BerkleyDB-4.3/lib
-R/opt/app/nonc++/BerkleyDB-4.3/lib,g

The workaround is to run the build_ext command separately:

./python ../setup.py build_ext --library-dirs=... --rpath=...

It's not hard to work around this problem, but it's tedious to build
the command line args from the massive list of directories I have to
educate distutils about.

[issue3995] iso-xxx/cp1252 inconsistencies in Python 2.* not in 3.*

[Roumen Petrov]

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

Thanks Martin for correction: yes not reserved - assigned.

Jean-Michel, you test case is incorrect. You terminal is run in CP1252
where byte \x80 is shown as euro sing. But if you run terminal(if is
possible in reported operating system) in ISO-8859-{1|15} this byte is a
control character without visual representation.

To avoid "visual" ambiguity you should use hex representation of characters:
1) >>> unicode('\x80', 'cp1252')
u'\u20ac'
2) >>> unicode('\xa4','iso-8859-15')
u'\u20ac'

For the second case in you terminal you should enter:
>>> unicode('¤','iso-8859-15')
u'\u20ac'
'¤'(cp1252) = \xa4 = 164 = '€'(iso-8859-15)

I guess you understand what is incorrect in you report.

Ah, there's the problem.  It picks through LDFLAGS looking for -L but fails
to pay attention to -R.  I'll see if I can work up a patch.

Also, I'm seeing this problem on Solaris.  I suppose it's possible that
linkage on OS X records the location of the libraries it finds, sort of
implicitly doing a -R.

[Nick Edds]

Nick Edds <[EMAIL PROTECTED]> added the comment:

The currently attached patch works in Python2.5 not Python2.6, so I will
update it for 2.6 when I get the chance. But as it is currently written,
the default behavior is not multiprocess. Instead, if you want
multiprocess, you specify how many processes you want when you run 2to3
from the command line. And as long as you've got multiple files to run
2to3 on and multiple cores, doing multiprocess 2to3 is significantly faster.

This seems to be a difficult problem. Doesn't the exact width depend on 
the terminal capabilities? and fonts, and combining diacritics...

An easy way to put the caret at the same exact position is to repeat the 
beginning of the line up to the offending offset:
   print "あいうえお"
   print "あいうえお^<--
But I don't know how to make it look less ugly.

At least my "one unicode char is one space" suggestion corrects the case 
of Western languages, and all messages with single-width characters.

[issue4012] Minor errors in multiprocessing docs

[Kent Johnson]

New submission from Kent Johnson <[EMAIL PROTECTED]>:

In the docs for AsyncResult
http://docs.python.org/dev/library/multiprocessing.html#multiprocessing.pool.AsyncResult

"get([timeout)" is missing a ]

In the example following, it refers to pool.applyAsync() in two places;
the docs spell this apply_async(), one of them must be wrong :-)

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

[STINNER Victor]

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

It's not a bug, it's a feature! Python3 rejects invalid byte sequence
(according to the "default system encoding") from the command line or
environment variables. listdir(str) will also drop invalid filenames.
Yes, we need a PEP (a FAQ) about invalid bytes sequences.

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

Confirmed that nothing seems broken on my OS X 10.5 laptop (doing a
unix-style build, not a framework build).

[issue3736] super is a built-in type

[Raymond Hettinger]

Raymond Hettinger <[EMAIL PROTECTED]> added the comment:

The super() docs have been updated to be more clear.  It is still listed
amongst built-in functions -- that list doesn't separate callables that
are also types, so super() is appropriately listed side-by-side with
tuple().
