[issue3403] Unexpected default arguments behaviour

[SukkoPera]

New submission from SukkoPera <[EMAIL PROTECTED]>:

I have just encountered a Python behaviour I wouldn't expect. Take
the following code:


class Parent:
a = 1

def m (self, param = a):
print "param = %d" % param

class Child (Parent):
a = 2

p = Parent ()
p.m ()

c = Child ()
c.m ()


I would expect to receive the following output:
param = 1
param = 2

But actually I get:
param = 1
param = 1

Is this the correct behaviour, and then why, or is it a bug? For
reference, I am using Python 2.5.1 on GNU/Linux.

There has been a short discussion about this at
http://groups.google.it/group/comp.lang.python/browse_thread/thread/9f740eea131e7ef2/56fd4e120a069a1d#56fd4e120a069a1d.

[issue3403] Unexpected default arguments behaviour

[Georg Brandl]

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

This is another "problem" due to the fact that parameter defaults are
evaluated once during function definition, not every time the function
is called. This is expected and will not change.

[issue3404] wrong precision in float formatting

[Hagen Fürstenau]

New submission from Hagen Fürstenau <[EMAIL PROTECTED]>:

This seems to be wrong:

>>> "{0:.2}".format(1.2345)
'1.2'

The same happens for format specifiers "g" and "n", but not for "f":

>>> "{0:.2f}".format(1.2345)
'1.23'

With empty format specifier it can even get really wrong:

>>> "{0:.1}".format(1.2345)
'1.0'

[issue3404] wrong precision in float formatting or doc error

[Hagen Fürstenau]

Hagen Fürstenau <[EMAIL PROTECTED]> added the comment:

Just found it documented for the % operator: There precision is number
of digits before and after decimal point for format "g". 

But then the documentation for 2.6 is wrong:

"The precision is a decimal number indicating how many digits should be
displayed after the decimal point for a floating point value."

[issue3362] locale.getpreferredencoding() gives bus error on Mac OS X 10.4.11 PPC

[cfr]

cfr <[EMAIL PROTECTED]> added the comment:

A work-around when using python from a shell environment (e.g. from a
bash shell in Terminal) is to issue

export __CF_USER_TEXT_ENCODING=0x1F5:0:0

before starting python. I haven't yet worked out how to apply this to
GUI apps. I tried editing ~/.MacOSX/environment.plist and
~/.CFUserTextEncoding but neither strategy prevents the crash.

I assume the fix works because it means one of the explicitly listed
encodings matches so things never get as far as the code which triggers
the error.

Without the fix, my environment contained

__CF_USER_TEXT_ENCODING=0x1F5:39:79

which does not, apparently, correspond to any of the encodings
explicitly listed in _localemodule.c.

[issue3405] Add support for the new data option supported by event generate (Tk 8.5)

[Guilherme Polo]

New submission from Guilherme Polo <[EMAIL PROTECTED]>:

Follows a patch that adds support for the new data option supported
event generate. It allows virtual events to pass a tcl object.

This patch is only intended to correctly support tcl objects, trying to
pass other objects (like a dict) will result in None being returned. If
you want to correctly pass and receive a dict, make it an attribute of
the tcl object being passed.

E.g.:

import Tkinter

def handle_it(event):
print event.data.something

root = Tkinter.Tk()
root.something = {1: 2}
root.after(1, lambda: root.event_generate('<>', data=root))
root.bind('<>', handle_it)
root.mainloop()

[issue3406] LocaleTextCalendar and LocaleHTMLCalendar break without a locale

[WoLpH]

New submission from WoLpH <[EMAIL PROTECTED]>:

Steps to reproduce:
>>> import calendar
>>> calendar.LocaleHTMLCalendar()
Traceback (most recent call last):
  File "", line 1, in 
  File "/usr/lib/python2.5/calendar.py", line 540, in __init__
locale = locale.getdefaultlocale()
AttributeError: 'NoneType' object has no attribute 'getdefaultlocale'

The same goes for LocaleTextCalendar, the problem is caused by this 
code which obviously would never work:
if locale is None:
locale = locale.getdefaultlocale()

The fix should be quite easy, rename the local variable and it will 
work again :)

Just as an added note: with the new changes made to fix_imports, this is

[issue3334] 2to3 looses indentation on import fix

[Nick Edds]

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

I believe the problem was that in the case of this fix, rather than
using set_prefix to give the new node the same prefix as before,
new.prefix = was used. Here is the one line fix which preserves the
prefix in the example given.

[issue3376] Use Python 3 lexer for 3.0 docs

[Benjamin Peterson]

New submission from Benjamin Peterson <[EMAIL PROTECTED]>:

I'm attaching two patches. One, for the Sphinx trunk, adds a
pygments_default_lexer option. The other, for the py3k branch, changes
the default lexer to python3. It also includes a rather hacky, overriden
highlightlang directive that changes the lexer from 'python' to
'python3' and calls the real highlightlang directive. This would
probably be better solved by adding a lexer_aliases option or something
to Sphinx. Note this doesn't work because the pygments version in SVN
doesn't have the Python 3 lexer.

This behavior has reappeared in the 2.6 beta releases:

Should a new bug be opened for this?  (I can't find one but I'm not too

[issue1242657] list(obj) can swallow KeyboardInterrupt

[Karen Tracey]

Karen Tracey <[EMAIL PROTECTED]> added the comment:

Thanks for responding.

It had been fixed.  2.4/2.5 behave like so:

Python 2.5.1 (r251:54863, Mar  7 2008, 04:10:12) 
[GCC 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> class F(object):
... def __iter__(self):
... yield 23
... def __len__(self):
... print 'len called, raising KeyboardInterrupt'
... raise KeyboardInterrupt
... 
>>> f = F()
>>> list(f)
len called, raising KeyboardInterrupt
Traceback (most recent call last):
  File "", line 1, in 
  File "", line 6, in __len__
KeyboardInterrupt
>>> 

It just seems to have regressed in 2.6.

[issue3408] urllib incomplete and urllib2 does not exist

[vizcayno]

vizcayno <[EMAIL PROTECTED]> added the comment:

Ok.

In the python 3.0b2 on line documentation that comes with the .msi 
installer:

1) Search with word urllib and access the fourth line found: "urllib — 
Open arbitrary resources by URL" 

2) Search with word urllib2 and select first line found: urllib2 — 
extensible library for opening URLs.

In these cases documentation refers to 3.0b1, I must say.

Many thanks for your attention and guidelines.

[issue3409] ElementPath.Path.findall problem with unicode input

[Uwe Hoffmann]

New submission from Uwe Hoffmann <[EMAIL PROTECTED]>:

[issue3410] platform.version() don't work as expected in Vista in portuguese

[Felipe Portella]

New submission from Felipe Portella <[EMAIL PROTECTED]>:

Using Vista in Portuguese platform.version is returning "32bits" 
instead of "6.0.6001". This is because in file platform.py line 379 
thee regular expression try to search for the word "Version" in 
english, while in Portuguese the command ver will return "Versão".

To solve this issue simple change:

'Version ([\d.]+))')

for

 '\S+ ([\d.]+))')

[issue3379] Option to not-exit on test

[Barry A. Warsaw]

Barry A. Warsaw <[EMAIL PROTECTED]> added the comment:

I'm not sure it's a good idea.  When exit=False, don't you lose the
results?  It would be better to return the results, but then that makes
for an ugly API (changing the return value based on an argument is a
general no-no in Python).

It would seem better to add a new method that returned the results
instead of exiting.  You'd probably want to refactor runTests().

[issue1869] Builtin round function is sometimes inaccurate for floats

[George Boutsioukis]

George Boutsioukis <[EMAIL PROTECTED]> added the comment:

The issue is that the implementation of round includes multiplying the
number by 10**ndigits, thus unnecessarily losing some precision for
large numbers within the IEEE754 double limits. This means that even
smaller numbers can produce these results for higher ndigit values, eg.

>>> round(56294995342131.5, 3) #one less digit
56294995342131.508

In the submitted patch I used modf to split the number and keep the
integral intact.

[issue3414] frameworkinstall doesn't create Python.app, which breaks python

[Erick Tryzelaar]

New submission from Erick Tryzelaar <[EMAIL PROTECTED]>:

Hello again!

It looks like doing "make frameworkinstall maninstall" isn't creating 
"Python.framework/Versions/3.0/Resources/Python.app", so when I try to 
run python it errors out with: "python3.0: execv: 
/opt/local/Library/Frameworks/Python.framework/Versions/3.0/Resources/Py
thon.app/Contents/MacOS/Python: No such file or directory". In order to 
get that file created, I need to manually run "cd Mac && make 
install_Python".

This patch fixes it, but I'm not sure if this is the proper fix:

[issue3415] Interpreter error when running a script under debugger control

[Nir]

New submission from Nir <[EMAIL PROTECTED]>:

Interpreter error results in erroneous exception when running a script
under debugger control.

Full repro description:
On Windows System, try to run idle.py under the inspection of pdb.py. 
Note that you must set a breakpoint somewhere otherwise pdb will not
trace the script and the issue will not surface.

You should get the bad exception in line 295 of multicall.py

Python complains that a local variable has been used before being
declared while in effect it has been a couple of lines before that point.

[issue2532] file that breaks 2to3 (despite being correct python)

[engelbert gruber]

engelbert gruber <[EMAIL PROTECTED]> added the comment:

The much simpler input might be another problem::

  # this is accepted
  b = ("a = 0\n" * 100)
  # this one breaks it
  ("a = 0\n" * 100)

this looks similar to ``map(None, t)`` on a line by itself is 
translated to ``list(map(None, t))`` and the message "You should use a 
for loop her"
