[issue21727] Ambiguous sentence explaining `cycle` in itertools documentation

[Raymond Hettinger]

Raymond Hettinger added the comment:

I see no real difference here and AFAICT the current wording has not caused any 
confusion since it was written a decade ago.

[issue12387] IDLE save keyboard shortcut problem

[Terry J. Reedy]

Terry J. Reedy added the comment:

I pushed Roger's patch so that the Windows section of config-keys.def is in a 
consistent state. However, this does not fix the problem for 
config-extensions.def or user versions of config-keys.def. A) The basic method 
of the key dialog does not allow entry of proper pairs. B) it is easy to forget 
to enter both versions when using the advanced method or editing a file 
directly.

So rather than develop a similar patch for the Unix block, which is always 
missing the uppercase version of key-bindings, our GSOC student will work on 
code to add the 'other' version when alpha key-bindings are read. If and when 
that works, the Unix block will work as is and the Windows block can have 
removed what will then become duplicates.

[issue634412] RFC 2387 in email package

[Abhilash Raj]

David: What about his API then?
   https://gist.github.com/maxking/b3ed4f54674e5f480275

Here cids are generated behind the scenes when the html part is added and those 
 cids are assigned to the attachments on the first come basis?
Like {0} is replaced by the cid of `roasted-asparagus.jpg`, I think you get the 
idea?

I will post a brief summary of this discussion to email-sig list later today.

[issue21714] Path.with_name can construct invalid paths

[Antony Lee]

Antony Lee added the comment:

I have the patch almost ready, but ran into another issue: should 
"path.with_name('foo/')" be allowed?  It may make sense to treat it like 
"path.with_name('foo')", just like 'Path("foo/") == Path("foo")'.

The implementation is also simpler with it, as it can reuse the "parse_parts" 
approach used by "with_suffix".  But this also raises a separate issue, which 
is that with the current implementation, we have 
"Path('foo').with_suffix('.bar') == Path('foo').with_suffix('.bar/')", and that 
is less reasonable.  Should I open a separate issue for that?

[issue21728] Confusing error message when initialising type inheriting object.__init__

[R. David Murray]

R. David Murray added the comment:

See issue 7963 for a clue to why you get this message.  That is, it is 
object.__new__ that is getting called, not object.__init__, and __new__ methods 
result in different error messages than __init__ methods.  I don't know if 
there is a practical way to make it better.  For example you also have this:

>>> a = A('abc', 'xyz')
Traceback (most recent call last):
  File "", line 1, in 
TypeError: decoding str is not supported
>>> a = A('abc', 2, 3, 54)
Traceback (most recent call last):
  File "", line 1, in 
TypeError: str() takes at most 3 arguments (4 given)

Hmm.  There's a conflict marker in that patch.

I *think* that if you do an 'hg pull --rebase' and then give your repository

tried it with the URL you sent me and it generated a diff that contained 
unrelated changes, which is why I suggest the hg pull --rebase).

Thanks you for the patch. It may be good to add a unit test for this.

[issue21728] Confusing error message when initialising type inheriting object.__init__

[Gerrit Holl]

New submission from Gerrit Holl:

When I initialise a class that doesn't define its own __init__, but I still 
pass arguments, the error message is confusing:

>>> class A: pass
... 
>>> A(42)
Traceback (most recent call last):
  File "", line 1, in 
TypeError: object() takes no parameters

Although it is correct that object() takes no parameters, it would be more 
correct to state that A() does not take any parameters.

[issue20580] IDLE should support platform-specific default config defaults

[Terry J. Reedy]

Terry J. Reedy added the comment:

I am not completely sure what you are asking. Config-keys.def has 4 Idle 
Classic sections, one each for Windows, Unix, Mac (still needed?), and OSX. On 
my Windows install, the one for Windows is preselected. I have presumed the the 
appropriate selections are made for other systems. If so, your opening sentence 
'provide different default settings depending on which platform it is running,' 
would be true already. If not, that would be a bug.

ConfigHandler.IdleConf.GetCoreKeys has hard-coded backups that probably work on 
Windows and Unix but not Max/OSX. I don't know if the 'Alt' to 'Option' 
replacement is applied to these are not.

If 'Alt' to 'Option' is insufficient for key bindings in config-extensions.def, 
I don't know what the answer is. Non-mac extension writers are unlikely to know 
what else to do.

Can any of the editing of Mac/Makefile be moved into runtime?

In "all versions by default share the same user configuration files", does 
versions mean 2.7, 3.4, 3.5 on one machine? If so, the statement describes a 
great feature that I would not change. If 'versions' means Windows Idle on one 
machine and OSX Idle on another machine, then the statement make no sense to me 
as we do not deliver user configuration files. If you mean multiple OS versions 
on the same machine, and it is possible to login as the same user with 
different Oses (I have no idea if this is so), then I could see a problem.

[issue634412] RFC 2387 in email package

[R. David Murray]

R. David Murray added the comment:

It is a clever idea, and might be worth considering, but it doesn't feel 
natural to have to specify the attachments before the html.  What I'd really 
like is an API that hides the messy details of the RFC from the library user, 
and I haven't thought of anything I'm satisfied with yet.  Specifically, it 
would be great if the 'keys' could be specially formatted strings ("@mypicid1@" 
or something like that) and the helper would automatically replace them with 
cids in both the html and the attachments.

It would probably be worth taking this discussion to the email-sig mailing list.

[issue21712] fractions.gcd failure

[Tim Peters]

Tim Peters added the comment:

@pacosta, if Mark's answer is too abstract, here's a complete session showing 
that the result you got for gcd(2.7, 107.3) is in fact exactly correct:

>>> import fractions
>>> f1 = fractions.Fraction(2.7)
>>> f2 = fractions.Fraction(107.3)
>>> f1
Fraction(3039929748475085, 1125899906842624) # the true value of "2.7"
>>> f2
Fraction(7550566250263347, 70368744177664)   # the true value of "107.3"
>>> fractions.gcd(f1, f2)  # computed exactly with rational arithmetic
Fraction(1, 1125899906842624)
>>> float(_)
8.881784197001252e-16

But this will be surprising to most people, and probably useless to all people. 
 For that reason, passing non-integers to gcd() is simply a Bad Idea ;-)

[issue21727] Ambiguous sentence explaining `cycle` in itertools documentation

[Matt Deacalion Stevens]

New submission from Matt Deacalion Stevens:

https://docs.python.org/3.5/library/itertools.html#itertools.cycle

The first sentence sounds a bit ambiguous:
"Make an iterator returning elements from the iterable and saving a copy of 
each."

Suggestion:
"Make an iterator that returns elements from the iterable and saves a copy of 
each."

[issue21726] Unnecessary line in documentation

[Reid Price]

New submission from Reid Price:

https://docs.python.org/2/distutils/examples.html#pure-python-distribution-by-package

Chrome on Linux

The last (parenthetical) sentence is not needed.

  "(Again, the empty string in package_dir stands for the current directory.)"

because there is no package_dir option in the example.

< Preceding Text >
  ...

If you have sub-packages, they must be explicitly listed in packages, but any 
entries in package_dir automatically extend to sub-packages. (In other words, 
the Distutils does not scan your source tree, trying to figure out which 
directories correspond to Python packages by looking for __init__.py files.) 
Thus, if the default layout grows a sub-package:

/
setup.py
foobar/
 __init__.py
 foo.py
 bar.py
 subfoo/
   __init__.py
   blah.py
then the corresponding setup script would be

from distutils.core import setup
setup(name='foobar',
  version='1.0',
  packages=['foobar', 'foobar.subfoo'],
  )

(Again, the empty string in package_dir stands for the current directory.)

[issue14102] argparse: add ability to create a man page

[Oz Tiram]

Oz Tiram added the comment:

Hi, 

I have been wanting this feature for quite a long time. IMHO, binaries and 
scripts should always include a man page. The Debian developers require that. 
However, man pages have a 'bizarre' format. 
Long talk, short time. I did implement something. I tested it on Python 2.7 
since my project currently only supports Python 2.7. 
I think it should not be complicated to port to Python 3.X. 

I doubt if the correct place for formatting a man page should be in argparse.py 
itself. My solution is an extension of Andial's brecht solution that uses 
ofcourse argparse.

You can see it in action in https://github.com/pwman3/pwman3

I am also attaching the code here. 

I hope you will find this file useful. I would appreciate your comments too. 

Regards, 
Oz

[R. David Murray]

R. David Murray added the comment:

Milan: your patch looks good for the most part.  Now that I committed the 
decode_data patch you should modify it so that SMTPUTF8 implies 
decode_data=False (otherwise we *don't* have an 8-bit-clean channel).  Please 
either attach the modified patch here or link the repository such that the 
patch can be generated (for rietveld review).

I'll need to play with it for a bit to make sure there's nothing more needed.

[issue21724] resetwarnings doesn't reset warnings registry

[Antoine Pitrou]

New submission from Antoine Pitrou:

There seems to be no (official) way to reset the warnings registry; in 
particular, resetwarnings() doesn't reset it. It makes it difficult to get 
repeatable warning messages, e.g. at the command prompt, because the shortcut 
path will silence messages which were already emitted, even if the filter have 
been changed to "always" in-between.

[issue21723] Float maxsize is treated as infinity in asyncio.Queue

[Vajrasky Kok]

New submission from Vajrasky Kok:

import asyncio

loop = asyncio.get_event_loop()
q = asyncio.Queue(maxsize=1.2, loop=loop)
q.put_nowait(1)
q.put_nowait(1)
q.put_nowait(1)
q.put_nowait(1)
q.put_nowait(1)
 and so on

It seems counter intuitive for my innocent eyes. As comparison with the 
traditional queue:

import queue
q = queue.Queue(maxsize=1.2)
q.put(1)
q.put(1)
q.put(1) -> blocking

Here is the patch to make the behaviour consistent with its sibling.

[issue19662] smtpd.py should not decode utf-8

[R. David Murray]

R. David Murray added the comment:

Thanks, Maciej. 

I tweaked the patch a bit, you might want to take a look just for your own 
information.  Mostly I fixed the warning stuff, which I didn't explain very 
well.  The idea is that if the default is used (no value is specified), we want 
there to be a warning.  But if a value *is* specified, there should be no 
warning (the user knows what they want).  To accomplish that we make the actual 
default value None, and check for that.  I also had to modify the tests so that 
warnings aren't issued, as well as test that they actually get issued when the 
default is used.

I also added versionchanged directives and a whatsnew entry, and expanded the 
decode_data docs a bit.

This patch teaches distutils/command/upload.py to return a non-zero exit code

Should be applied against tip.

[issue21719] Returning Windows file attribute information via os.stat()

[STINNER Victor]

STINNER Victor added the comment:

> Instead of the somewhat cryptic name "winattrs", I suggest to call it 
> st_file_attributes (...)

On Windows, os.stat() calls GetFileInformationByHandle() which fills a 
BY_HANDLE_FILE_INFORMATION structure, and this structure has a dwFileAttributes 
attribute. The os.stat() calls also GetFileType().
http://msdn.microsoft.com/en-us/library/windows/desktop/aa364952%28v=vs.85%29.aspx

So I agree that os.stat().st_file_attributes is less surprising for Windows 
developers and it is more homogenous with FILE_ATTRIBUTE_xxx constants.

[issue21205] Add a name to Python generators

[STINNER Victor]

STINNER Victor added the comment:

gen_qualname.patch: add a new "__qualname__" attribute to generators and change 
how the name is set: use the name of the function, instead of using the name of 
the code.

Incompatible changes of this patch:

- repr(generator) now shows the qualified name instead of the name
- generator name comes from the function name which may be different

If the function has a name different than the code (if the function name was 
changed, for example by @functools.wraps), the generator now gets the name from 
the function, no more from the code object. IMO it's the expected behaviour, 
and it's more useful.

I'm writing on email to python-dev to discuss these changes.

[Antoine Pitrou]

Antoine Pitrou added the comment:

I think raising ValueError is the way to go. Would you like to try writing a 
patch for it?

[issue21718] sqlite3 cursor.description seems to rely on incomplete statement parsing for detection

[R. David Murray]

R. David Murray added the comment:

It is true that the sqlite interface does not support WITH currently.  It is an 
interesting question whether or not we could change this as a bug fix or 
not...I suppose it depends on whether or not it changes any behavior other than 
making .description work.

[issue21720] "TypeError: Item in ``from list'' not a string" message

[David Szotten]

New submission from David Szotten:

```
>>> __import__('fabric.', fromlist=[u'api'])
Traceback (most recent call last):
  File "", line 1, in 
```

accidentally ended up with something like this via some module that was using 
`unicode_literals`. stumped me for a second until i realised that my variable 
was a string, but not `str`. would be nice with a custom error message if this 
is a unicode string, explicitly mentioning that these must not be unicode or 
similar

[issue21719] Returning Windows file attribute information via os.stat()

[Ben Hoyt]

New submission from Ben Hoyt:

I asked recently on python-dev [1] about adding a "st_winattrs" attribute to 
stat result objects on Windows, to return the full set of Windows file 
attribute bits, such as "hidden" or "compressed" status. Copying from that 
thread for a bit more context here:

Python's os.stat() simply discards most of the file attribute
information fetched via the Win32 system calls. On Windows, os.stat()
calls CreateFile to open the file and get the dwFileAttributes value,
but it throws it all away except the FILE_ATTRIBUTE_DIRECTORY and
FILE_ATTRIBUTE_READONLY bits. See CPython source at [2].

Given that os.stat() returns extended, platform-specific file
attributes on Linux and OS X platforms (for example,
st_blocks, st_rsize, etc), it seems that Windows is something of a
second-class citizen here.

There are several questions on StackOverflow about how to get this
information on Windows, and one has to resort to ctypes. For example,
[3].

To solve this problem, I think we should add a "st_winattrs" attribute to the 
object returned by os.stat() on
Windows. And we should add the relevant Win32 FILE_ATTRIBUTE_* constants to the 
"stat" module.

Then, similarly to existing code like hasattr(st, 'st_blocks') on
Linux, you could write a cross-platform function to determine if a
file was hidden, something like so:

def is_hidden(path):
if startswith(os.path.basename(path), '.'):
return True
st = os.stat(path)
return getattr(st, 'st_winattrs', 0) & FILE_ATTRIBUTE_HIDDEN != 0

There was general support for this idea on python-dev (see [4] [5] [6]), so I'd 
love to see this in Python 3.5.

Basically we need to add a "st_winattrs" integer attribute to the win32_stat 
struct in posixmodule.c and add the FILE_ATTRIBUTE_* constants to _stat.c, as 
well as adding Windows-specific tests and documentation.

I've never compiled CPython on Windows, but I aim to provide a patch for this 
at some stage soonish. Feedback and other patches welcome in the meantime. :-)

[issue21718] sqlite3 cursor.description seems to rely on incomplete statement parsing for detection

[mike bayer]

New submission from mike bayer:

Per DBAPI and pysqlite docs, .description must be available for any SELECT 
statement regardless of whether or not rows are returned.  However, this fails 
for SELECT statements that aren't simple "SELECT"s, such as those that use CTEs 
and therefore start out with "WITH:":

import sqlite3
conn = sqlite3.connect(":memory:")

cursor = conn.cursor()
cursor.execute("""
create table foo (id integer primary key, data varchar(20))
""")

cursor.execute("""
insert into foo (id, data) values (10, 'ten')
""")

cursor.execute("""
with bar as (select * from foo)
select * from bar where id = 10
""")

assert cursor.description is not None


cursor.execute("""
with bar as (select * from foo)
select * from bar where id = 11
""")

assert cursor.description is not None


the second statement returns no rows and cursor.description is None.   
Libraries like SQLAlchemy which rely on this to determine that the statement 
supports fetchone() and similar are blocked.

[issue21712] fractions.gcd failure

[Mark Dickinson]

Mark Dickinson added the comment:

Agreed with Tim.

Oddly enough[1], remembering that with binary floating-point numbers, what you 
see is not what you get[2], it turns out that 8.881784197001252e-16 (= 
Fraction(1, 1125899906842624)) is in fact *exactly* the right answer, in that 
it's a generator for the additive subgroup of the rationals generated by 2.7 (= 
Fraction(3039929748475085, 1125899906842624)) and 107.3 
(=Fraction(7550566250263347, 70368744177664)).

[1] Actually not so odd, given that % is a perfectly exact operation when 
applied to two positive finite floats.

[issue3068] IDLE - Add an extension configuration dialog

[Tal Einat]

Tal Einat added the comment:

Ned, many thanks for the review and detailed feedback!

Here are responses to your comments

1. Thanks for the code suggestion regarding the menudefs! That's a good catch. 
I have an OSX box for such testing.

2. I'll check this out. Could you perhaps explain or point me to resources 
regarding how to run IDLE with various Tk implementations on OSX?

3. Unfortunately, IDLE's config mechanism doesn't have special support for 
options with only several valid values, as would have been ideal for 
ParenMatch's "style" parameter. As it is, these are just considered strings, 
and no explicit error occurs if an invalid value is specified. Without 
upgrading the config mechanism itself, the config dialog has no way of 
supplying the valid values and/or validating user input of such values. This 
could be useful, but should be considered a separate issue IMO. I would be 
happy to add relevant support to the dialog once the underlying support is 
implemented.

4. Regarding having thing updated only on new windows or after restart, AFAIK 
that is currently the case with many options in the existing config dialog. 
Ideally the behavior would be consistent for all config options, and even more 
ideally all config changes would take effect immediately. However, that would 
require major changes to IDLE. Again, I think this is outside the scope of this 
issue.

5. I completely agree that the button for boolean options looks horrible. 
Suggestions for a better Tk widget to use are welcome!

Finally, regarding
