What operating system is this on? What exact Python version are you using?

I can't reproduce this with r81614 on Linux.

[issue7946] Convoy effect with I/O bound threads and New GIL

[Gregory P. Smith]

Gregory P. Smith  added the comment:

Thanks for all your work Nir!  I personally think the BFS approach is the best 
we've seen yet for this problem!

Having read the thread you linked to in full (ignoring the tagents  
bikeshedding and mudslinging that went on there), it sounds like the general 
consensus is that we should take thread scheduling changes slowly and let the 
existing new implementation bake in the 3.2 release.  That puts this issue as a 
possibility for 3.3 if users demonstrate real world application problems in 3.2.

(personally I'd say it is already obvious that there are problems an wde should 
go ahead with your BFS based approach but realistically the we're still better 
off in 3.2 than we were in 3.1 and 2.x as is)

[issue7983] The encoding map from Unicode to CP932 is different from that of Windows'

[Marc-Andre Lemburg]

Marc-Andre Lemburg  added the comment:

Hye-Shik, could you please comment on this ?

The Windows version appears to replace private use code points with CJK 
compatibility idiographs, ie. uses standard Unicode code points rather than 
private escape code points (for round-trip safety).

[issue8859] split() splits on non whitespace char when ther is no separator given.

[Ezio Melotti]

Ezio Melotti  added the comment:

I think the problem is in the default encoding used when you call unicode() 
without specifying any encoding.
>>> '\xc5\xa0'.decode('iso-8859-1').split()
[u'\xc5']
>>> '\xc5\xa0'.decode('utf-8').split()
[u'\u0160']

[issue8859] split() splits on non whitespace char when ther is no separator given.

[Peter Landgren]

Peter Landgren  added the comment:

I am not sure I can follow you. I will try to be more specific.

The test string consists originally of one character; the Czech Š.

1. On Linux with Python 2.6.4
1.1 If I keep the original code line order:
label = obj.get()
print type(label), repr(label)
label = " ".join(label.split())
print type(label), repr(label)
label = unicode(label)
if len(label) > 40:
label = label[:40] + "..."

Both lines print type(label), repr(label) gives:
 '\xc5\xa0'

1.2 If I change order and take the unicode conversion first:
label = obj.get()
label = unicode(label)
print type(label), repr(label)
label = " ".join(label.split())
print type(label), repr(label)
if len(label) > 40:
label = label[:40] + "..."

Both lines print type(label), repr(label) gives:
 u'\u0160'

2. On Windows with Python 2.6.5
2.1 The original code line order:
The lines print type(label), repr(label) gives
 '\xc5\xa0'
 '\xc5'
 8217: ERROR: gramps.py: line 138: Unhandled exception
 

2.2 If I change order and take the unicode conversion first:
Both lines print type(label), repr(label) gives:
 u'\u0160'

3.
If I use this little code:
# -*- coding: utf-8 -*-
label = 'Š'
print type(label), repr(label)
label = " ".join(label.split())
print type(label), repr(label)
I get 
 '\xc5\xa0'
 '\xc5\xa0'
on both Linux and Windows.

The examples above under 1. and 2. comes from an application, Gramps.

There is still something I don't understand.

[Antoine Pitrou]

Antoine Pitrou  added the comment:

What do you mean, "works perfectly well under Linux"?
The error also happens under Linux here, and is expected: you can't call 
unicode() without an encoding and expect it to decode properly non-ASCII chars 
(and \xa0 is a non-ASCII char).

[issue8859] split() splits on non whitespace char when ther is no separator given.

[Ezio Melotti]

Ezio Melotti  added the comment:

Both on Linux and Windows I get:
>>> '\xa0'.isspace()
False
>>> u'\xa0'.isspace()
True

The Unicode char u'\xa0' is U+00A0 NO-BREAK SPACE, so unicode.split correctly 
considers it a whitespace.
However '\xa0' is not a whitespace, so str.split ignores it.
The correct solution is to convert your string to Unicode and then split.
I'd close this as invalid but I'd like you to confirm that the example I posted 
and that 'split' return the same result on both Linux and Windows before doing 
so (the fact that on Linux works it's probably caused by something else -- e.g. 
the label is already Unicode).

[issue8859] split() splits on non whitespace char when ther is no separator given.

[Peter Landgren]

New submission from Peter Landgren :

When the variable label is equal to '\xc5\xa0 Z\nX W'
this line sequence
label = " ".join(label.split())
label = unicode(label)
results in:
7347: ERROR: gramps.py: line 138: Unhandled exception
Traceback (most recent call last):
  File "C:\Program Files (x86)\gramps\gui\views\listview.py", line 660, in 
row_changed
self.uistate.modify_statusbar(self.dbstate)
  File "C:\Program Files (x86)\gramps\DisplayState.py", line 521, in 
modify_statusbar
name, obj = navigation_label(dbstate.db, nav_type, active_handle)
  File "C:\Program Files (x86)\gramps\Utils.py", line 1358, in navigation_label
label = unicode(label)
UnicodeDecodeError: 'utf8' codec can't decode bytes in position 0-1: invalid 
data

While this line sequence:
label = unicode(label)
label = " ".join(label.split())
gives correct result and no error.

With the error the variable label changes from
'\xc5\xa0 Z\nX W'
to
'\xc5 Z X W'
by the line:
label = " ".join(label.split())
Note '\xa0' has been dropped, interpreted as "whitespace"?
This happens on Windows. It works perfectly well on Linux.

Not that I can think of.  Like you pointed out, we should have removed the

[issue8858] socket.getaddrinfo returns wrong results for IPv6 addresses

[Antoine Pitrou]

New submission from Antoine Pitrou :

It seems socket.getaddrinfo gives wrong results for IPv6 address under py3k:

>>> pprint.pprint(socket.getaddrinfo("www.python.org", 0))
[(2, 1, 6, '', ('82.94.164.162', 0)),
 (2, 2, 17, '', ('82.94.164.162', 0)),
 (2, 3, 0, '', ('82.94.164.162', 0)),
 (10, 1, 6, '', (10, b'\x00\x00\x00\x00\x00\x00 \x01\x08\x88 \x00\x00\r')),
 (10, 2, 17, '', (10, b'\x00\x00\x00\x00\x00\x00 \x01\x08\x88 \x00\x00\r')),
 (10, 3, 0, '', (10, b'\x00\x00\x00\x00\x00\x00 \x01\x08\x88 \x00\x00\r'))]

The results given by 2.x make much more sense:
>>> pprint.pprint(socket.getaddrinfo("www.python.org", 0))
[(2, 1, 6, '', ('82.94.164.162', 0)),
 (2, 2, 17, '', ('82.94.164.162', 0)),
 (2, 3, 0, '', ('82.94.164.162', 0)),
 (10, 1, 6, '', ('2001:888:2000:d::a2', 0, 0, 0)),
 (10, 2, 17, '', ('2001:888:2000:d::a2', 0, 0, 0)),
 (10, 3, 0, '', ('2001:888:2000:d::a2', 0, 0, 0))]

[issue8446] buildbot: DeprecationWarning not raised for icglue (test_py3kwarn.TestStdlibRemovals)

[Ronald Oussoren]

Ronald Oussoren  added the comment:

The root cause of this test failure is that test_macos runs before 
test_py3kwarn.

That causes MacOS to be imported before test_py3k runs and that results in not 
raising the py3k warning by the time test_py3kwarn runs.

I propose removing MacOS from the list of modules that test_py3kwarn tests for 
now.

[issue8784] tarfile/Windows: Don't use mbcs as the default encoding

[Lars Gustäbel]

Lars Gustäbel  added the comment:

My expertise on Windows is rather limited, but as far as I understand the 
issue, I consider this a reasonable idea.
I think it is impossible to find a perfect default encoding, and utf-8 seems to 
be the best bet with regard to portability. IIRC most of the archivers on the 
Windows machines I have access to use latin-1, but I don't think that latin-1 
is a suitable default value. I don't know much about Windows internals and have 
no idea what mbcs really is, but it is actually not available on other 
platforms.

Perhaps I wasn't clear:

The VS2008 installer as well as the most of VS tool chain appear
to be 32-bit binaries and thus writes its keys and values into
Software\Wow6432Node\Windows\.

If you then run a 64-bit Python binary, it won't find the keys
under the regular Software\Windows\ reg path.

BTW: This was a fresh Vista and VS2008 installation.

Can you think of any reason that we shouldn't just copy the py3k implementation

replacing "if (PyLong_Check(w))" with "if (PyInt_Check(w) || PyLong_Check(w))"?

[issue8748] integer-to-complex comparisons give incorrect results

[Mark Dickinson]

Mark Dickinson  added the comment:

D'oh (again!)

which of course, it was, in issue 5211.  And we should have caught the 
richcompare coercion in that issue.  So I apologise:  getting rid of the 
PyNumber_CoerceEx call was the right thing to do---we should have already done 
that in issue 5211.

[issue8854] msvc9compiler.py: find_vcvarsall() doesn't work with VS2008 on Windows x64

[Martin v . Löwis]

Martin v. Löwis  added the comment:

This shouldn't be necessary. If a 32-bit Python looks into the registry, it 
will get automatically redirected to Wow6432Node. If a 64-bit Python looks into 
the registry, it shouldn't have any interest in values stored in Wow6432Node.
