[issue22362] Warn about octal escapes 0o377 in re

2014-09-12 Thread STINNER Victor

STINNER Victor added the comment:

re_octal_escape_overflow_raise.patch: you should write a subfunction to not 
repeat the error message 3 times.

+if c  0o377:

Hum, I never use octal. 255 instead of 0o377 would be less surprising :-p By 
the way, you should also check for negative numbers.

 -3  0xff
253

Before,  0xff also converted negative numbers to positive in range 0..255.

[issue22389] Generalize contextlib.redirect_stdout

2014-09-12 Thread STINNER Victor

STINNER Victor added the comment:

redirect_stdout(stderr, stream) looks wrong to be: you want to redirect 
stdout or stderr?

If you want to redirect something else (ex: stdin), you can still implement the 
very simple pattern:

old_stdin = sys.stdin
try:
  sys.stdin = mock_input
  ...
finally:
  sys.stdin = old_stdin

By the way, I'm not convinced that we should add redirect_stderr.

@Barry: How many usage of this new functions do you see in the standard library?

[issue19232] Speed up _decimal import

2014-09-12 Thread STINNER Victor

STINNER Victor added the comment:

We could speed up the import further by not importing collections
in _decimal.  That could be done once structseq fully implements
the namedtuple protocol (for DecimalTuple).

I suggest to close this issue. I guess that importing decimal is already fast 
enough, and enhance structseq is a completly different issue. (Is there an open 
issue, just to get the link?)

IMO we should mention the write buffer limits (high- and low-water limits for 
write flow control). get_write_buffer_limits() and set_write_buffer_limits() 
methods of the transport are public, there is no reason to hide them.

Nick Coghlan added the comment:

I'm fine with adding redirect_stderr - better to have the obvious
counterpart, rather than hypergeneralising, or having to explain why it's
missing. It's *currently* missing largely on a wait for someone to ask
basis, and Barry asked.

(Tangentially related, I should do a contextlib2 release at some point, but
my previous CI provider shut down...)

[issue22348] Documentation of asyncio.StreamWriter.drain()

2014-09-12 Thread Martin Richard

Martin Richard added the comment:

Here is an other patch which mentions high and low water limits. I think it's 
better to talk about it, since it tells extactly what a full buffer and 
partially drained means.

On the other hand, StreamWriter wraps the transport but does not expose the 
set/get_write_buffer_limits() directly, you reach then through 
stream_writer.transport (which makes sense, StreamWriter is here to help 
writing, not to do plumbery) - so I did not mention the functions.

[issue21356] Support LibreSSL (instead of OpenSSL): make RAND_egd optional

2014-09-12 Thread Michał Górny

Michał Górny added the comment:

 In CPython, the _ssl module is compiled in C. How can we check if libssl 
 provides RAND_egd() or not at compile time?

How about... checking whether the function is provided? Unless I'm missing some 
major point, AC_CHECK_FUNC should be good enough.

 Is there a way to check if libssl is OpenSSL or LibreSSL?

Why would you want to do that? Do you want to make silly assumptions on API 
depending on provider name, and then add extra conditionals for versions?

[issue22394] Update documentation building to use venv and pip

2014-09-12 Thread Brett Cannon

New submission from Brett Cannon:

Now that we have ensurepip, is there any reason to not have the Doc/ Makefile 
create a venv for building the docs instead of requiring people to install 
sphinx into either their global Python interpreter or some venv outside of 
their checkout? Basically it would be like going back to the old Makefile of 
checking out the code but instead do a better isolation job and let pip manage 
fetching everything, updating the projects, etc.

[issue22253] ConfigParser does not handle files without sections

2014-09-12 Thread kernc

kernc added the comment:


 I am dubious that there are any with a mixture of both sections and
 additional option lines at the top without a section.


rsyncd.conf [1] is one such example, and I wouldn't say there aren't
countless more in the wild.

 Anyone writing an app and planning to parse a .ini file can add [Start] or
 [Setup] at the top.


Indeed. Here lies the problem of this unfortunate issue:
MissingSectionHeaderError is only ever caught [9] to mitigate this **awful
default behavior** and attach a dummy section at the top, as you say. Or
can anyone care to propose another relevant use case for this poorly (un-)
thought through exception?

 I think a more useful new configparser feature would be to keep comment
 lines and write them back out after a configuration is changed.


While this is very much off-topic, configobj [3] does too seem to have done
so since ages.

[issue22396] AIX posix_fadvise and posix_fallocate

2014-09-12 Thread David Edelsohn

New submission from David Edelsohn:

As with Solaris and Issue10812, test_posix fadvise and fallocate fail on AIX.  
Python is compiled with _LARGE_FILES, which changes the function signature for 
posix_fadvise and posix_fallocate so that off_t is long long on 32 bit system 
passed in two registers.  The Python call to those functions does not place the 
arguments in the correct registers, causing an EINVAL error.  This patch fixes 
the failures in a similar way to Solaris ZFS kludge for Issue10812.

See similar Ruby issue: https://bugs.ruby-lang.org/issues/9914 .

As workaround we can redeclare posix_fadvise as int posix_fadvise(int fd, long 
offset, long len, int advice) on 32-bit AIX with enabled _LARGE_FILES. More 
safe option is to disable posix_fadvise in such case (as Ruby had done).

[issue22398] Tools/msi enhancements for 2.7

New submission from Steve Dower:

This patch has some minor changes to the build scripts for Python 2.7 on

Tools/msi scripts are not used or that the changes won't have an impact.

The Tools/msi/msi.py changes to use environment variables are mostly to make my 
life easier. Apparently the old way was to actually modify the file before 
making an official release...

The Tools/msi/msilib.py fix is necessary because of some new files that were 
added for 2.7.9. Technically it's a release blocker, though it won't actually 
hold anything up since I spotted it.

[issue22398] Tools/msi enhancements for 2.7

2014-09-12 Thread Zachary Ware

Zachary Ware added the comment:

Actually, I think the method Martin used was to create a local config.py in 
Tools/msi/, which provided the proper settings for the release.  See 
http://hg.python.org/cpython/file/2.7/Tools/msi/msi.py#l37

Either way, the buildbots are completely unaffected by Tools/msi, and I don't 
think anything actually uses PCbuild/build_tkinter.py (unless you do :)), so 
since the script is now yours, I'd say you're clear to change as you like.

[issue22398] Tools/msi enhancements for 2.7

2014-09-12 Thread Steve Dower

Steve Dower added the comment:

Thanks for confirming. Somehow I never noticed the import config line - guess 
that's a pattern I'm not really used to seeing. Still, I prefer having the env 
variables there as I invoke the scripts through some batch files (very specific 
to my machine, unfortunately, but the 3.5 ones will be more generic).

And since you mention it, apparently I'm not using build_tkinter.py any more 
either. I was at one point, hence the fix. I'll leave it in there - we can 
probably remove the file completely but no harm in leaving it.

[issue22399] Doc: missing anchor for dict in library/functions.html

2014-09-12 Thread Philippe Dessauw

New submission from Philippe Dessauw:

There is a missing anchor for the dict functions in the documentation at 
library/functions.html. It is present in the documentation of all python 
version.

It seems to impact cross-referencing in Sphinx (using intersphinx).

[issue22354] Idle: highlite tabs

2014-09-12 Thread Terry J. Reedy

Terry J. Reedy added the comment:

I agree that this is an issue, and I believe others have made similar comments 
or requests, but I cannot find an existing issue for this.

By experiment, it is possible to tag a tab and change the background color for 
the spaces a tab is visually converted to.  

import tkinter as tk
root = tk.Tk()
text = tk.Text(root)
text.pack()
text.insert('insert', 'a\tb')
text.tag_add('TAB', 1.1, 1.2)
text.tag_config('TAB', background='#ffd')  # light yellow, or
text.tag_config('TAB', background='#eee')  # light gray

http://infohost.nmt.edu/tcc/help/pubs/tkinter/web/text-methods.html
The other tag configuration options that refer to text, such as overstrike and 
underline, have no visual effect. Neither does non-zero borderwidth.

I am reluctant to add visible characters. The need to delete them would 
complicate converting tabs to spaces and saving files.  Since Idle normally 
converts tabs to spaces on input, they are not common in edited files.  The 
main issue, as you mention, is code imported from elsewhere.

Some issue remain.

1. Tagging tabs: I presume this is no problem, but will not know until there is 
a patch.

2. The priority of the TAB tag relative to others. The importance of this 
depends on the next question.

3. Should tab space in comments and strings be shaded?  I think so.  If so, 
should the shading match the comment/string foreground color?

[issue22376] urllib2.urlopen().read().splitlines() opening a directory in a FTP server randomly returns incorrect result

2014-09-12 Thread Terry J. Reedy

Terry J. Reedy added the comment:

You should have just added a new message to #22375 with the revision.

#15002 ends with This is fixed in 3.4 and 3.5. I will backport to 2.7 ( I 
think, it is worth it). Please check whether the backport has been done or 
whether current you still have a problem with the latest 2.7.8.  If so, did the 
3.4 patch, included in 3.4.1, fix the issue (ie, install 3.4.1 and test).  If 
you code works on 3.4.1 and not on 2.7.8, you could add a request for a 
backport to #15002.

I agree with making a complete and separate sentence.  There are 3 variations.

Add parenthetical note after last sentence.  (Contributed by me.)

Add note on next line after short line.

--
Add note after a blank line.

I guess version 2 will be formatted the same as version 1. In 3.4 What's New I 
only say one instance of the 3rd, blank line style, for the multi-paragraph 
Improvements to Codec Handling, which it arguable was appropriate.
