[issue17852] Built-in module _io can loose data from buffered files at exit

[Charles-François Natali]

Charles-François Natali added the comment:

When you say Python 2, I assume you mean CPython 2, right?
Because - AFAICT - files got flushed only by accident, not by design.
For example, I suspect that Jython doesn't flush files on exit (since
the JVM doesn't), and I guess IronPython neither.

That's the problem with implementation-defined behavior ;-)

[issue17838] Can't assign a different value for sys.stdin in IDLE

[Roger Serwy]

Roger Serwy added the comment:

I agree with Serhiy that the patch should be updated to better explain why the 
extra reference to stdin was being held. The attached patch provides that 
update in case anyone considers applying it in the future.

Terry, are you suggesting that the code should read like "sys.__stdin__ = 
sys.stdin" within MyHandler in Lib/idlelib/run.py ?

[issue17859] improve error message for saving ints to file

[anatoly techtonik]

New submission from anatoly techtonik:

I needed to write some bytes to file and got this message.

>>> hex = open('hex', 'wb')
>>> for x in range(0, 0xff, 0x11):
...   hex.write(x)
...
Traceback (most recent call last):
  File "", line 2, in 
TypeError: 'int' does not support the buffer interface

The cause of the error is not that 'int' doesn't support some interface (which 
is strange already, because the function analyzes and writes int, not the int 
writes itself), but because it is impossible to know how many binary bytes the 
int type should take when written.

In Python 2 the solution is:
  ...
  hex.write(chr(x))

But in Python 3 this is again:
  TypeError: 'str' does not support the buffer interface

In Python 3 the solution is:
  ...
  hex.write(x.to_bytes(1, 'little'))

[issue17806] Add keyword args support to str/bytes.expandtabs()

[Ezio Melotti]

Ezio Melotti added the comment:

Without patch:
$ ./python -m timeit -s 'et = "a\tb\tc\td\te".expandtabs' 'et()'
100 loops, best of 3: 0.672 usec per loop
$ ./python -m timeit -s 'et = "a\tb\tc\td\te".expandtabs' 'et(4)'
100 loops, best of 3: 0.744 usec per loop
$ ./python -m timeit -s 'et = "a\tb\tc\td\te".expandtabs' 'et(8)'
100 loops, best of 3: 0.762 usec per loop

$ ./python -m timeit -s 'et = "a\tb\tc\td\te".expandtabs' 'et()'
100 loops, best of 3: 0.658 usec per loop
$ ./python -m timeit -s 'et = "a\tb\tc\td\te".expandtabs' 'et(4)'
100 loops, best of 3: 0.73 usec per loop
$ ./python -m timeit -s 'et = "a\tb\tc\td\te".expandtabs' 'et(8)'
100 loops, best of 3: 0.769 usec per loop
$ ./python -m timeit -s 'et = "a\tb\tc\td\te".expandtabs' 'et(tabsize=4)'
100 loops, best of 3: 1.84 usec per loop
$ ./python -m timeit -s 'et = "a\tb\tc\td\te".expandtabs' 'et(tabsize=8)'
100 loops, best of 3: 1.89 usec per loop

If "tabsize" is not used the performances seem the same, if it's used it's 2-3 
times slower.  I don't think expandtabs is used in performance-critical paths, 
but if it is the patch shouldn't affect it as long as people don't add 
"tabsize" to the call.

FTR the reason to add this is consistency (Python functions allow you to pass 
positional args as keywords too) and readability (s.expandtabs(3) might be read 
as "expand at most 3 tabs" or something else).

[issue17859] improve error message for saving ints to file

[Ezio Melotti]

Ezio Melotti added the comment:

Maybe the error could be replaced with something like:
TypeError: write() requires an object that supports the buffer interface, not 
''

But that's a bit long and also not entirely accurate, because the type accepted 
by write depends on the type of the file (binary or text).  The first problem 
could be solved by using "requires a bytes-like object"[0], the second problem 
could be fixed by omitting the name of the function:
TypeError: a bytes-like object is required, not ''

[0]: #16518 has a discussion about the best term to describe "objects that 
support the buffer protocol"

Oh, I just did a grep on the Python 3.3.0 code base and couldn't
find any hits. Was the issue you mentioned applied to the 3.3.1 dot
release ?

If so, then those new mentions will have to be fixed as well,
of course.

[issue12220] minidom xmlns not handling spaces in xmlns attribute value field

[R. David Murray]

R. David Murray added the comment:

Thanks for the patch.  It would be nice to have a test before we commit this.  
The tests should use assertRaisesRegex to look for something specific to this 
error...probably the word 'syntax'...in the error text.

On the other hand, if the spaces are technically legal, is calling it a syntax 
error appropriate?  Perhaps the message should instead say something like 
"spaces in URIs is not supported"?

[issue17724] urllib -- add_handler method refactoring for clarity

[R. David Murray]

R. David Murray added the comment:

I presume you closed this bug yourself because you decided it probably wasn't 
worth applying it?  I'm inclined to agree.  Cleaning up the code would be nice, 
but since the existing code works fine, changing it *just* to clean it up 
probably isn't worth the code churn or the chance of introducing an unexpected 
new bug.  

If we were also fixing a bug while doing the rewrite, it would be a different 
story.  So I'll try to keep this patch in mind if we have occasion to fix 
anything in that code.

[issue17860] subprocess docs lack info how to use output result

[anatoly techtonik]

New submission from anatoly techtonik:

http://docs.python.org/3/library/subprocess.html

A common confusion is that result from subprocess calls in Python 3 is bytes, 
not string, and needs to be converted.

The problem is complicated because you need to know the encoding of 
input/output streams. This should be documented at least.

[issue17358] imp.load_module() leads to the improper caching of the 'file' argument

[Brett Cannon]

Brett Cannon added the comment:

I figured out why testing was difficult; the file is only read from if it's 
necessary. That means if you are trying to load source which has bytecode 
available which is legitimate it will simply skip over the source and read from 
the bytecode.

So in the end I just fixed it without a test since it's for a marginal case for 
a deprecated module. Plus the fix is rather simple and still passed the test 
suite.

[issue17859] improve error message for saving ints to file

[Éric Araujo]

Éric Araujo added the comment:

I don’t understand that the first message says.

If one wants to call the write method of a file object opened in binary mode, 
one needs to pass bytes, as the doc surely explains.  The same error that is 
seen here with ints would be seen with any other objects.  A more practical way 
is to use print (with its file, sep and end parameters) which will do the 
conversion for you.

[issue17862] itertools.chunks(iterable, size, fill=None)

[anatoly techtonik]

New submission from anatoly techtonik:

The history:
2007 - http://bugs.python.org/issue1502
2009 - http://bugs.python.org/issue6021

I'd like to resurrect this proposal again, but name it:
  itertools.chunks(iterable, size, fill=None)

Two reasons.
1. practicality  - top itertools request on StackOverflow
http://stackoverflow.com/search?tab=votes&q=%5bpython%5d%20%2bitertools

2. performance
the time should be a constant for a fixed-length iterable regardless of a size 
of chunk, but in fact the time is proportional to the size of chunk

{{{
import timeit

print timeit.timeit(
  'grouper(3, "x"*40)', setup='from __main__ import grouper', 
number=1000
)
print timeit.timeit(
  'grouper(30, "x"*40)', setup='from __main__ import grouper', 
number=1000
)
}}}

1.52581005407
14.6219704599


Addressing odd length user stories from msg87745:
1. no exceptions - odd end is an easy check if you need it
2. fill-in value - provided
3. truncation - just don't set fill-in value
3.1. if you really need fill-in as None, then an itertools.TRUNCATE value can 
be used as a truncation parameter
4. partially filled-in tuple - not sure what that means

Raymond, your opinion is critical here. =)

[issue10079] idlelib for Python 3 with Guilherme Polo GSoC enhancements

[Terry J. Reedy]

Terry J. Reedy added the comment:

With PEP343 accepted, we can apply changes more uniformly.

I think each of the changes listed should be separate issues with separate 
review, as most already are (msg149930). 

"Run a script without saving it first." I am sure this has been mentioned on at 
least 1 other issue, but I cannot find an issue devoted to this.

"The "PseudoStderrFile" in PyShell.py brings the shell forward if an error 
occurs." The PseudoFiles were updated last fall. Has this behavior been added?

[issue17863] Bad sys.stdin assignment hands interpreter.

[Terry J. Reedy]

New submission from Terry J. Reedy:

This appears to be Python 3 specific. On 2.7.4 (Win7):
>>> import sys
>>> sys.stdin='abd'
>>>

With fresh 3.4 repository debug build, prompt never appears, ^C, ^D are 
ignored. Must close with window's [X] button. With fresh 3.3, get repeated 
[62312 refs] lines. One could guess that they are generated but suppressed in 
3.4.

There is a possibility that this is specific to debug builds; I cannot 
currently build or run one for 2.7. However, there is no problem with Idle 
running (on Windows) with 3.3/3.4 pythonw-d. (In other words, see same behavior 
as 2.7 above.)

[issue17838] Can't assign a different value for sys.stdin in IDLE

[Terry J. Reedy]

Terry J. Reedy added the comment:

Roger: yes. This solves immediate problem and makes Idle more like console 
interpreter. Same should be done for all three.

Serhiy: the sole and documented purpose of sys.__stdxyz__ is to serve as backup 
bindings for the three i/o streams, so rebinding them is senseless. I would be 
willing to say 'you get what you deserve if you do that'. But since console 
tolerates double rebinding, we can make Idle do so too. Again, same should be 
done for all three streams.

See attached patch. It seems to work, but someone please recheck for typos. Are 
we sure that binding streams to handler object cannot cause problems, such as 
during shutdown with atexit handlers?

[issue17642] IDLE add font resizing hot keys

[Alejandro Rodas]

Alejandro Rodas added the comment:

I have made a patch to zoom in and out with  and  
events, respectively. I'll upload it soon since the test suite is giving me an 
error in test_multiprocessing, even before writing the patch.

I have taken a look at ZoomFont.py of IdleX and it also has the option to reset 
the font size to its original value, but I don't know if this feature was 
wanted to be added too. However, ZoomFont controls the size of the LineNumber 
extension, while this patch only changes the font of the editview's text widget.

[issue17864] IDLE won't run

[Ben Read]

New submission from Ben Read:

I am installing Python 3.31 on a Mac running OS 10.8.2 and have already 
installed ActiveTCL 8.5.13. When I try and launch IDLE, the icon appears on the 
dock for a second and then disappears and the application doesn't run. I have 
already installed both Python and Active TCL in the same way on two other Macs 
and it has run just fine, so I don't know why it's not running on this one. Is 
there anything specific that would cause this to happen?

Thanks,
Ben

[issue17642] IDLE add font resizing hot keys

[Abhishek Kumar]

Abhishek Kumar added the comment:

I have submitted a patch that is working fine on Windows and on Ubuntu. I have 
used ZoomFont.py of IdleX.

On pressing Ctrl+ or Ctrl- it changes the user configuration and updates the 
font of all open windows as there is a common user configuration for all 
windows. I have removed polling from CodeContext instead I set font of 
CodeContext on every font change.

As this is my first patch. Please review it and give your valuable feedback.

[issue17864] IDLE won't run

[Ned Deily]

Ned Deily added the comment:

OK, assuming you are using a default install of Python 3.3.1, try opening a 
terminal window (Terminal.app) and launching IDLE from there by typing:

/usr/local/bin/python3.3 -c 'import sys;print(sys.version)'
/usr/local/bin/python3.3 -m idlelib

and report what messages you see there.

Also, are there any other messages with "com.apple.launchd.peruser" or 
"org.python.IDLE" immediately before that one?  You can use Console.app to see 
if there are any relevant crash reports under User Diagnostic Reports.  You 
could use Activity Monitor.app to see if there is already an IDLE or Python 
process running.  If you can, try logging -out and -in and/or rebooting.  And 
which Python 3.3.1 did you install: from the python.org 3.3.1 64-bit/32-bit 
installer, from the python.org 3.3.1 32-bit-only installer, or from somewhere 
else?

[issue17863] Bad sys.stdin assignment hands interpreter.

[R. David Murray]

R. David Murray added the comment:

Indeed, in both 3.3.0 non-debug and 3.4 tip debug, python starts consuming 100% 
of the CPU.  I'm guessing there is some subtlety involving the new IO system 
involved here.

Python 2.7 debug build acts as you indicate for your 2.7 non-debug build.

All my tests are on linux, and I had to kill -HUP the python process.  As you 
say, ctl-C (and ctl-D, not surprisingly) were ignored.

[issue17864] IDLE won't run

In response to the first command:

[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)]

…and the second command:

Warning: unable to create user config directory
/Users/ben/.idlerc
 Check path and permissions.
 Exiting!

I've checked console and activity monitor and cannot see any further reference 
to IDLE. The message I sent previously was the only one shown in 'All Messages' 
after a marker I added to know where to start from. 

I downloaded Python 3.31 from the official site and selected the 64bit version. 
I ran the ActiveTCL 8.5.13 download first. 

Thanks,

Ben

[issue17864] IDLE won't run

[Ned Deily]

Ned Deily added the comment:

That's really odd.  It looks you have a permissions problem with your home 
directory. On startup, IDLE attempts to create the directory .idlerc in your 
home directory, /Users/ben, if it doesn't exist already.  If for some reason 
the directory creation fails, IDLE aborts.  Interestingly, if the directory 
exists but IDLE lacks write permission to create files in it, it does not abort 
but posts a warning message in a window.  Perhaps it could be a little more 
consistent about that.  But still, this appears to be avery unusual situation.  
I can't think of any reason why IDLE would be unable to create a directory 
unless you have some security system installed or some unusual access control 
list setting.  The most likely reason is just a plain old permission problem on 
your home directory.  Try this in a terminal session:

cd ~
ls -lde ~

You should see something similar to this:
drwxr-xr-x+ 38 nad  staff  2992 Apr 28 15:26 /Users/nad/
 0: group:everyone deny delete

if the permissions string is missing the "w" ("dr-xr-x"), that means you do not 
have write permission to your home directory and can't create new directories 
there.  In that case, 

mkdir ~/.idlerc

should fail.  (This is essentially what IDLE is trying to do.)

If you are missing write permission on your home directory, you *should* be 
able to fix it by doing:

chmod u+w ~

[issue17642] IDLE add font resizing hot keys

[Alejandro Rodas]

Alejandro Rodas added the comment:

I have uploaded my patch as well, it doesn't make use of tkfont (just vanilla 
Tkinter methods) and it works both in Python 2.7 and 3.4 without the need of 
any import.

I think the main difference with Abhishek Kumar's version is that mine does not 
use idleConf to retrieve and set the font size. However, the original 
ZoomFont.py of IdleX does not use it. Is it really necessary?

Sorry, I submitted a patch which only works on Windows. This one has been 
tested on Ubuntu too.

[issue17863] Bad sys.stdin assignment hands interpreter.

[Terry J. Reedy]

Terry J. Reedy added the comment:

In searching for an existing issue about this, there seemed to be other 
edge-case stdin problems. I don't think that they were all usage errors. This 
problem was revealed by an accidental usage error that should have lain dormant 
until an exception was raised upon first use by input() (as happened in 2.7).

[issue17865] PowerPC exponentiation and round() interaction

[Ellen Wang]

New submission from Ellen Wang:

This is only on a PowerPC, specifically a p2020, running Debian 7.0 wheezy, 
python 2.7.3.

Calling round() seems to corrupt something (in the floating point state?) that 
causes subsequent exponentiation (the ** operator) to be wrong:

Python 2.7.3 (default, Jan  2 2013, 16:38:11)
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> 2 ** -2
0.25
>>> round(1)
1.0
>>> 2 ** -2
0.1253019036571362

Cool.  Huh?

[issue17865] PowerPC exponentiation and round() interaction

[Ellen Wang]

Ellen Wang added the comment:

Here's an example that uses only math library functions and float literals, 
presumably with a simpler code path:

Python 2.7.3 (default, Jan  2 2013, 16:38:11)
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import math
>>> math.exp(-2.0)
0.1353352832366127
>>> math.ceil(1.0)
1.0
>>> math.exp(-2.0)
0.23902241864785234

By the way, the equivalent C program (using exp() and ceil()) on the same 
platform behaves correctly, so it's not an obvious libc or fpu problem.

[issue15518] Provide test coverage for filecmp.dircmp.report methods.

[Eli Bendersky]

Eli Bendersky added the comment:

Thanks for the heads up Chris. Since I'm a bit busy myself lately, it's fine to 
wait until you have time to complete the patch. I'll review it then.
