descriptor of function object creates bound method.  You can google "descriptor 
python".

> accessed?

No "should", just "can".

`3 + 5 is 8` can be True of False by language definition, while `3 + 5 == 8` is 
always True.

Like it, descriptor may or may not same instance by language definition.

You're confused because you're using wrong guide; `is`.
There are many cases that language spec doesn't define same instance is 
returned or not.

Abe Leite  added the comment:

Hi Inada-san,

Could you explain (or send me a link to) what happens when an instance method 
is accessed and why this should be different from what happens when an unbound 
method is accessed?

The `is` keyword has been very useful for me in introspection cases and that is 
why I'm confused that it doesn't behave as expected here.

Thank you,

Abe

[Inada Naoki]

Inada Naoki  added the comment:

It is a designed behavior.

I agree that it looks strange to some users who don't know implementation.
And that's why people should not use `is` normally, except some use cases (e.g. 
`is None`.)

[issue36176] Make IDLE Autocomplete / Calltip Window Colors Configurable

[Kristoffer Law]

New submission from Kristoffer Law :

IDLE utilizes the foreground text color from KDE/Qt (Window Text) for the 
autocomplete and calltip windows. If a dark theme is selected and the window 
text changed to white or another bright color, it can be difficult or 
impossible to see due to lack of contrast. There does not appear to be any way 
to change these particular windows text or background color settings from 
IDLE's configuration.

Modifying the variables under line 192 in autocomplete_w.py (bg="white") and 
line 83 in calltip_w.py (background="#e0") allows these windows to change 
background colors.

Perhaps add these as settings in IDLE's config? Or force the foreground color 
to always be black?

Python 3.7.2
GCC 8.2.1

KDE Plasma Version: 5.15.2
KDE Frameworks Version: 5.55.0
Qt Version: 5.12.1

(This is my first bug submission ever, so if I missed something obvious, I 
apologize in advance)

[issue33944] Deprecate and remove pth files

[Ivan Pozdeev]

Ivan Pozdeev  added the comment:

On 02.03.2019 9:01, Barry A. Warsaw

In all the cases you've described, Python is no different from any other 
Linux software. E.g. I can install something into /etc/profile.d that 
would break the shell or set an envvar that would change the behavior of 
standard utilities.
This is by design: Linux is designed for maximum interoperability, so 
there's only one of each component in the system and everything uses it 
whenever it needs that kind of functionality. It does support multiple 
versions of the same software, but it's a compromise that significantly 
complicates maintenance (primarily how to disambiguate them when 
something requests just "component X"), so they strive to avoid it 
whenever possible.
Likewise, complete freedom for root to wreak havoc in the system is also 
by design: distro maintainers only test and support official packages; 
anything else you use is either your responsibility or an app supplier's 
if they provide official support (and are within their right to deny 
support if you tweak the environment beyond their support promise) -- 
same as for any other software as well.

This is not even specific to .pth files, either, so you won't really 
eliminate the problem by removing them. You can break any other part of 
Python in subtle ways just as well -- e.g. overwrite or override binary 
files with incompatible ones, causing segfaults in random places 
(https://stackoverflow.com/q/51816639/648265 ).

Now, Linux does have "lower tier environments" that don't automatically 
affect "higher tiers". 1) Software installed into /usr/local doesn't 
hijack system scripts thanks to absolute paths in their shebangs; 
software in /opt is not on PATH at all; 2) /etc/profile* and bashrc are 
only executed by login shells and interactive shells, not by scripts, 
limiting their effect to processes created within a user session; 3) 
anything within a user's profile or run as a regular user (including 
~/.bash*) doesn't affect system-wide settings and processes run as root.

Blindly replicating 2) won't do for Python, however. Unlike Bash which 
has all the functionality compiled in, Python has an external standard 
library and arbitrary additional packages. They both are essential for 
its operation as a system component that other software can use without 
additional manipulations, AND Python gives the user freedom on how to 
arrange them in the system. So there must be a way to provide any 
"additional manipulations" that may be needed that the built-in startup 
logic doesn't have. From administration POV, any such startup logic is a 
part of the core offer to the system: core files+libraries+connecting 
logic = Python system component, so it must be invoked whenever Python 
is invoked.
And we do already have ways to apply startup code only to a "lower-tier 
environment" if such a need arises: user-specific -- user site; 
interactive-specific -- PYTHONSTARTUP.  There's no such thing as a 
"login shell" for Python but there's Python run in a user session; 
/etc/profile* can set envvars that would apply only there.

So it seems to me that what you are asking for is "/etc/profile.d for 
Python". When designing such a feature, note, however, that the concept 
of login sessions is completely alien to Python. I believe a way to 
provide an additional site-packages directory will do (I can't readily 
see an already available way to do so in 
https://docs.python.org/3/using/cmdline.html ).

[issue36175] Identity of bound methods

[Abe Leite]

New submission from Abe Leite :

The following code produces unexpected behavior in all versions of Python I 
have tested.

>>> class a:
... def method(self): pass

>>> inst = a()
>>> inst.method is inst.method
False

It appears that id(inst.method) changes each time inst.method is accessed by 
normal means.

So the tuple (id(inst.method), id(inst.method)) will have the same item 
repeated, but the tuple (id(inst.method), inst.method, id(inst.method)) will 
not.

Note that for unbound methods and other functions, this issue does not occur.

This creates a transparency issue for bound instance methods taking the place 
of functions.

My apologies if this is a design decision that has already been resolved! It 
just seemed like a strange behavior to me.

[issue26707] plistlib fails to parse bplist with 0x80 UID values

[Jon Janzen]

Jon Janzen  added the comment:

I recently upgraded my python version and my hot-patch broke due to changes in 
bpo-32072 (GH-4455).

It reminded me of this b.p.o., and after reading through the messages to remind 
myself where the patch stood I realized that my tone friendly towards the end 
was not overly.

@ronaldoussoren, I apologize if I offended.

In other news, I re-implemented the patch (and filed a new pull-request) due to 
the following:

* Things got spread out over too many commits
* NSKeyedArchiver only uses binary mode, so I removed the XML compatibility
* I also wrote a few tests to verify the UID implementation

[issue31861] add aiter() and anext() functions to operator module

Dima Tisnek  added the comment:

https://www.python.org/dev/peps/pep-0525/#aiter-and-anext-builtins kinda 
promised `aiter` and `anext` built-ins.

This ticket seems idle.

Perhaps it's time for the decider club to either remove that language from 
PEP-525 or make a plan for aiter/anext?

You'll see on that page that 'state' is listed as a Widget Command and not an

    STANDARD OPTIONS

        -class, undefined, undefined 
        -cursor, cursor, Cursor 
        -style, style, Style

        pathName configure ?option? ?value option value ...? 
        pathName get 
        pathName identify x y 
        pathName instate statespec ?script?

        pathName fraction x y 

    SCROLLING COMMANDS

        prefix moveto fraction 
        prefix scroll number units 
        prefix scroll number pages 

If you notice, your listing of the options includes the 6 options listed above: 
command, orient, takefocus, cursor, style, class.  It doesn't list any of the 
other widget commands, such as cget or configure.  state is like those and not 
like the options.

In other words, you would use `w.state(['!disabled', 'selected'])` as shown in 
the example on the New Mexico Tech link.

[issue36172] csv module internal consistency

[Martin Panter]

Martin Panter  added the comment:

The documentation 
 says you should 
“open the files with newline=''.” IMO this is an unfortunate quirk of the CSV 
module. Everything else that I know of in the Python built-in library either 
works with binary files, which typically do no newline translation in Python 3, 
or is fine with newline translation enabled in text mode. See also Issue 10954 
about making the behaviour stricter.

[issue36172] csv module internal consistency

[Shane]

New submission from Shane :

It occurred to me there is a slight mismatch in the behavioral consistency of 
the csv module (at least on Windows, Python 3.X).  Specifically, csv.writer() 
and csv.reader() treat the line terminator slightly differently.  To boil it 
down to a concise example:

#==
import csv

data = [[1, 2, 3], [4, 5, 6]]

with open('test.csv', 'w') as fout:
csv.writer(fout).writerows(data)

with open('test.csv', 'r') as fin:
data2 = list(csv.reader(fin))

print(data, data2, sep='\n')

>>> 
[[1, 2, 3], [4, 5, 6]]
[['1', '2', '3'], [], ['4', '5', '6'], []]
#==

So because csv.writer() uses lineterminator = '\r\n', data and data2 have a 
different structure (data2 has empty rows).  To me this seems undesirable, so I 
always go out of my way to use lineterminator = '\n'.  

#==
import csv

data = [[1, 2, 3], [4, 5, 6]]

with open('test.csv', 'w') as fout:
csv.writer(fout, lineterminator='\n').writerows(data)

with open('test.csv', 'r') as fin:
data2 = list(csv.reader(fin))

print(data, data2, sep='\n')

>>>
[[1, 2, 3], [4, 5, 6]]
[['1', '2', '3'], ['4', '5', '6']]
#==


Then the input and output have the same structure.  I assume there was a reason 
lineterminator = '\r\n' was chosen as default, but for me there is no benefit 
wrt csv files.  It seems like we would be better off with the more consistent, 
"reversible" behavior.

Alternatively, the default behavior of csv.reader() could be changed.  But in 
either case, I feel like their default behaviors should be in alignment.

Thoughts?  Thanks for reading.

[issue36114] test_multiprocessing_spawn dumps core in AMD64 FreeBSD CURRENT Shared custom

[Pablo Galindo Salgado]

Pablo Galindo Salgado  added the comment:

After some investigation, this turns out to be more complicated, as this 
'python.core' turns to be a core dumped from some of the processes spawned by 
test_multiprocessing_spawn. So the real problem is that 
test_multiprocessing_spawn segfaults, as in https://bugs.python.org/issue36116. 
I think this may be the same underlying problem. I will change the title to 
reflect this.

[issue36125] Cannot cross-compile to more featureful but same tune

[Xavier de Gaye]

Xavier de Gaye  added the comment:

Re-opening and setting the stage as 'needs patch': at least the 
cross-compilation should fail with a clear message when the cross-built 
libraries names and those of the native interpreter have the same suffix.

> Assuming that you can rely on the loader to not open target binaries when 
> they're on the path to load from is unwise.

Meanwhile a workaround may be to build the native interpreter with Py_DEBUG 
defined (using the --with-pydebug configure option) so that libraries names 
become different.

[issue35889] sqlite3.Row doesn't have useful repr

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

I have the same doubts as Berker. sqlite3.Row represents a data from a 
database. Databases are used in particularly for storing a large amount of data 
which can not be all loaded in RAM. Therefore sqlite3.Row can contain a data 
with a very long repr.

If you need to inspect the sqlite3.Row object, it is easy to convert it to a 
list. If you want to see keys together with values, it is not hard to make a 
list of key-value pairs or a dict: list(zip(row.keys(), row)) or 
dict(zip(row.keys(), row)).

That's exactly the glitch.  I'm cross-compiling to a more powerful IA process

that you can rely on the loader to not open target binaries when they're on the 
path to load from is unwise.
