[issue13519] Tkinter rowconfigure and columnconfigure functions crash if minsize, pad, or weight is not None

[aoi.leslie]

New submission from aoi.leslie :

Symptom:
When use tkinter Widget class's rowconfigure or columnconfigure function (The 
two functions are defined in baseclass Misc.) to get the setting for a row or 
column (The setting is a dict containing fields 'minsize', 'pad', 'weight', and 
'uniform'.), if field value of 'minsize', 'pad', or 'weight' is a positive 
integer instead of None, then error |TypeError: argument of type 'int' is not 
iterable| is raised. Field value of 'uniform' does not matter.

Speculation:
File |tkinter.__init__|, function |_grid_configure|, line 1279, code |elif '.' 
in value| caused this error. The code assumes the value is a str, but the value 
can be int.

Suggested Fix:
Change the code block around line 1279 to handle int value as well.

[issue13517] readdir() in os.listdir not threadsafe on OSX 10.6.8

[Thouis (Ray) Jones]

Thouis (Ray) Jones  added the comment:

Further testing indicates the problem is in the filesystem itself (either the 
server or client, but not in python).

Serializing the loops calling readdir / readdir_r fixes the problem on my 
system, but using either function in a large number of parallel threads causes 
some directory entries to be missed (usually 2 entries in a row, oddly enough). 
 I was also able to cause 'find' to fail in the same way by placing the 
filesystem under sufficient stress, which I hadn't managed to do before 
(leading me to trust the filesystem more than I should have).

I apologize for the noise.  I've closed this bug report.

[Éric Araujo]

Éric Araujo  added the comment:

I’m perfectly happy to let Lars do it next week or next month, there is no 
rush.  The existing patch may even require very little or no change, as 
Nadeem’s module (in the stdlib) provides the same classes than the other lzma 
module which was used by the patch.

I preferred to add a separate test, because only the tests with "assert False"

[issue13520] Patch to make pickle aware of __qualname__

[sbt]

New submission from sbt :

The attached patch makes pickle use an object's __qualname__ attribute if 
__name__ does not work.

This makes nested classes, unbound instance methods and static methods 
picklable (assuming that __module__ and __qualname__ give the correct 
"address").


BTW, It would not be hard to make instance methods picklable (and, as a 
by-product, class methods) by giving instance methods a __reduce__ method 
equivalent to

  def __reduce__(self):
return (getattr, (self.__self__, self.__name__))

Is there any reason not to make such a change?

[issue12067] Doc: remove errors about mixed-type comparisons.

[Ezio Melotti]

Ezio Melotti  added the comment:

Would it be ok to state that:
1) <, >, ==, >=, <=, and != compare the values of two objects;
2) the two objects don't necessarily have to be of the same type;
3) with == and !=, objects of different types compare unequal, unless they 
define a specific __eq__ and/or __ne__;
4) with <, >, <=, and >=, the comparison of objects of different types raises a 
TypeError, unless they define specific __lt__, __gt__, __le__, and __ge__;
5) some built-in types define these operations, so it's possible to compare 
e.g. int and floats;

This should summarize the possible behaviors.  There's no reason IMHO to expose 
implementation details and to special case built-in types (unless their 
comparison is actually different and doesn't depend on __eq__, __ne__, etc.).

Good question. A simple counter is the only thing we can enable by default, 
though. Anything else would require recompiling Python, which is probably a 
barrier for most users.

> Did you already found real leaks using your hack^Wpatch? (was

yes, c6dafa2e2594 was found with this patch. It's the only one, though (there's 
also a leak in test_ctypes but I don't want to investigate :-)).

Thanks. I'm not sure that's a good approach for protocol 3: some pickles
created by Python 3.3 would not be readable by Python 3.2. That's why I
initially added that idea to PEP 3154, for a hypothetical protocol 4.

However, perhaps it is possible to use the same reduce/getattr trick you
are proposing for instance methods?

I don't see any personally. Actually, multiprocessing has a Pickler
subclass called ForkingPickler which does something similar (in
Lib/multiprocessing/forking.py).

[issue12067] Doc: remove errors about mixed-type comparisons.

[Terry J. Reedy]

Terry J. Reedy  added the comment:

In Python 3, where all classes inherit from object, the default rules are, by 
experiment, (which someone can verify from the code) simpler than you stated.

3. By default, == and /= compare identities.
4. By default, order comparisons raise TypeError.
ob <= ob raises even though ob == ob because ob is ob.

I am not sure of the method look-up rules for rich comparisons, but perhaps the 
following are true:

3) with == and !=, an object is equal to itself and different objects (a is not 
b) compare unequal, unless the class of the first define a specific __eq__ and 
__ne__;

4) with <, >, <=, and >=, comparison raises a TypeError, unless the class of 
the first object defines specific __lt__, __gt__, __le__, and __ge__, or the 
class of the second defines the reflected method (__ge__ reflects __lt__, 
etcetera);

What is not clear to me is whether the reflected method is called if the first 
raises TypeError. The special method names doc (reference 3.3) says "A rich 
comparison method may return the singleton NotImplemented if it does not 
implement the operation for a given pair of arguments. 
...
There are no swapped-argument versions of these methods (to be used when the 
left argument does not support the operation but the right argument does); 
rather, __lt__() and __gt__() are each other’s reflection, __le__() and 
__ge__() are each other’s reflection, and __eq__() and __ne__() are their own 
reflection."

Does 'not supported' mean 'raises TypeError', 'returns NotImplemented', or 
both? If the last, I don't really understand the reason for NotImplemented 
versus TypeError. That point should be clarified in 3.3 also. And 3.3 should be 
referenced in the comparisons section.

I think point 5 should say a bit more: builtin numbers compare as expected, 
even when of different types; builtin sequences compare lexicographically.

>>> help(Frame.rowconfigure)
Help on function grid_rowconfigure in module tkinter:

grid_rowconfigure(self, index, cnf={}, **kw)
Configure row INDEX of a grid.

Valid resources are minsize (minimum size of the row),
weight (how much does additional space propagate to this row)
and pad (how much space to let additionally).
'''
The above implies that setting uniform=1 (in your code) works because it is 
ignored. From docs on the web, it appears that 'uniform' is valid and is just 
missing from our doc string. It is different from the other three, though, in 
jperhaps not being restricted to int values.

You are right that (line 1259)
def _grid_configure(self, command, index, cnf, kw):
expects strings (which is what tcl uses). I do not know enough, though, to know 
where the bug is. I do notice, however, that setting with a Python int matches 
online Python examples and that the code runs without the attempt to read the 
config.

[issue11838] IDLE: make interactive code savable as a runnable script

[Terry J. Reedy]

Terry J. Reedy  added the comment:

Roger Serway pointed me to the PastePyShell.py extension that is part of the 
IdleX package http://idlex.sourceforge.net/ 
That does the conversion when *pasting* interpreter text into an edit window. I 
would have File/Save do the same thing when saving the shell text to a .py file.

[issue13521] Make dict.setdefault() atomic

[Raymond Hettinger]

New submission from Raymond Hettinger :

A dialog on python-dev suggests that dict.setdefault() was intended to be 
atomic and that a number of experienced developers have deployed code relying 
on its atomicity:  
http://mail.python.org/pipermail/python-3000/2007-July/008693.html

The actual implementation shows a second call to PyDict_Setitem() which can 
call PyObject_Hash() which can call arbitrary Python code.   
http://hg.python.org/cpython/file/2.7/Objects/dictobject.c#l1937

This fix is straight-forward, use the results of the initial lookup to insert 
the default object.  This will make the operation atomic and it will make it 
faster.

[issue11838] IDLE: make interactive code savable as a runnable script

[Roger Serwy]

Roger Serwy  added the comment:

I considered saving directly from the shell but then I ran into a use-case 
problem. Saving the shell window as an runnable script will also save any 
syntax errors that were entered. A user would then have to open an editor to 
correct these errors.

A high-level task analysis would be as follows:
With "Save As Runnable", the user needs to save, open, and then fix.
With "Paste from Shell", the user needs to copy, paste, and then fix.


If you have suggestions for handling shell errors, I'm open to them.

[issue13519] Tkinter rowconfigure and columnconfigure functions crash if minsize, pad, or weight is not None

[aoi.leslie]

aoi.leslie  added the comment:

Setting the config has no problem. Only reading has.

The config is read from Tk at line 1270 by code

res = self.tk.call('grid',
   command, self._w, index)

. If each of the four options (minsize, pad, uniform, and weight) has been set 
to value 1, |res|'s value after the tk call would be a tuple |('-minsize', 1, 
'-pad', 1, '-uniform', '1', '-weight', 1)|. This explains why |uniform|'s value 
does not cause problem, because it is a str, while the other three's are int. 
Also int 0 does not cause problem because it is handled at line 1277 by code

if not value:
value = None

so the resulting option value appears as None in rowconfigure or 
columnconfigure's resulting dict.

In my speculation, the bug is that, when converting from the tuple returned by 
tk call into the resulting dict to be returned by rowconfigure or 
columnconfigure, the converting code assumes that the option values in the 
tuple returned by tk call are all str. But somehow only |uniform|'s value is 
str, while other three's are int.

[issue11838] IDLE: make interactive code savable as a runnable script

[Terry J. Reedy]

Terry J. Reedy  added the comment:

Either way, it would be nice to have erroneous commands flagged or filtered. 
That can be detected when the first line of output is 

Traceback (most recent call last):

I typically would copy, correct, and rerun a line until I get it correct, so I 
would want bad lines just removed. Others might prefer otherwise. I should take 
a look at your extension when I get a chance.
