[issue35634] kwargs regression when there are multiple entries with the same key

[Ammar Askar]

Ammar Askar  added the comment:

This change in difference is caused by 
https://github.com/python/cpython/commit/e036ef8fa29f27d57fe9f8cef8d931d4122d8223

The old code checked for duplicate arguments by essentially running 
`set().intersection(d)` and since `set().intersection(['a', 'a'])` is the empty 
set, it doesn't register as a duplicated argument. The newer code iterates over 
the keys in order to merge the dictionaries.

Note however that 3.5 is now is in security only mode: 
https://devguide.python.org/#branchstatus so its unlikely this behavior will be 
back-ported.

[issue35634] kwargs regression when there are multiple entries with the same key

[iceboy]

iceboy  added the comment:

I feel like we should not check the argument and allow overriding. If the 
argument checking is desired, can we also check when there is only a single 
kwargs? Currently `foo(**d)` still works in Python 3.6 with duplicated keys.

[issue35637] Factorial should be able to evaluate float arguments

[Yash Aggarwal]

New submission from Yash Aggarwal :

Factorial as of now accepts only integers or integral floats. 
I want to suggest extending the definition of float to accept all positive real 
numbers to be more consistent with general definition of factorial that uses 
gamma function.

What I am proposing is:
1. for integer value, the function should work as it does and return integer 
result.

2. for float input, both integer and non-integer valued, the returned value 
should be a floating point number.

3. the input domain should be extended to all real numbers except negative 
integers.

Such generalized function would feel more mathematically consistent.

[issue35638] Introduce fixed point locale awear format type for floating point numbers

[steelman]

New submission from steelman :

It is currently impossible to format floating point numbers with an arbitrary 
number of decimal digits AND the decimal point matching locale settings. For 
example no current format allows to display numbers ranging from 1 to 1000 with 
exactly two decimal digits.

[issue35636] remove redundant check in unicode_hash(PyObject *self)

[Stefan Behnel]

Stefan Behnel  added the comment:

Unlikely to get changed in Py3.4/5 anymore, since this is not even a bug fix. I 
wouldn't even fight for backporting, although 3.7 seems ok for it.

I agree that this code duplication is worth removing. I don't consider hashing 
the empty string important enough for leaving it in, especially because the net 
performance effect can at most be zero, if not negative, for the normal case of 
non-empty strings.

[issue35639] Lowecasing Unicode Characters

[Erdem Uney]

New submission from Erdem Uney :

assert 'ŞİŞLİ'.lower() == 'şişli'

Lowercasing the capital İ (with a dot on - \u0130) adds a unicode character 
\u0307 after i and if there is a following character it adds that dot (\u0307) 
over that character. The behavior is different in Python 2.7.10 where it adds 
the dot on top of 'i'.

Accord to Unicode Specifications character \u0130 should be converted to 
character \u0069.

[Mark Dickinson]

Mark Dickinson  added the comment:

See related discussion in issue #33083.

Are you aware that `math.gamma` and `math.lgamma` exist? These already provide 
the ability to compute the "factorial" of a non-integral input.

I'd be opposed to extending math.factorial to accept non-integral floats.

[issue35634] kwargs regression when there are multiple entries with the same key

[Rémi Lapeyre]

Rémi Lapeyre  added the comment:

I prepared a patch to make the check when there is only one dict, it may be the 
less surprising change.

BTW, I got lost when looking for the root cause  of this change because 
grepping for the error message did not work as it has line breaks:

-PyErr_Format(PyExc_TypeError,
-"%.200s%.200s got multiple "
-"values for keyword argument '%U'",
-PyEval_GetFuncName(func),
-PyEval_GetFuncDesc(func),
-key);

Can we add a note like 
https://www.kernel.org/doc/html/v4.12/process/coding-style.html#breaking-long-lines-and-strings
 to the PEP7?

> However, never break user-visible strings such as printk messages, because 
> that breaks the ability to grep for them.

It would help in such situations.

[issue35196] IDLE text squeezer is too aggressive and is slow

[Dan Snider]

Dan Snider  added the comment:

Not 100% sure if it's appropriate to post this here... so sorry if not. 

So anyway, the _MAX_COLS and _MAX_LINE constants used for `get_argspec` seem 
like they were intended to limit the generated text tips to at most 5 rows, 85 
characters wide, which makes sense, but isn't what happens at all.

Easy to just post an example of how the call signature isn't limited in any 
meaningful way, which can easily lead to a call tip millions of character long 
that obviously cannot be rendered and can maybe cause crashes:

# freshly started repl session
>>> if 1:
from idlelib.calltips import get_argspec
G = globals()
@get_argspec
def func(x, d=G): pass
print('len of func signature:', len(func))
print(f'len(repr(globals())): {len(repr(G)):_} ({len(G)} globals)')

len of func signature: 564
len(repr(globals())): 899 (10 globals)
>>> from numpy import *
>>> if 1:
from idlelib.calltips import get_argspec
G = globals()
@get_argspec
def func(x, d=G): pass
print('len of func signature:', len(func))
print(f'len(repr(globals())): {len(repr(G)):_} ({len(G)} globals)')
...
len of func signature: 45524
len(repr(globals())): 92_488 (604 globals)

[issue35641] IDLE: calltips not properly formatted for functions without doc-strings

[Tal Einat]

New submission from Tal Einat :

IDLE usually wraps call-tips to 85 characters.  However, for functions without 
a doc-string, this formatting is skipped.  This is an issue for functions with 
long signatures, e.g. due to having many arguments or due to having default 
values with long repr-s.

This appears to be caused by line 170 in Lib/idlelib/calltip.py being indented 
once too much. (see: 
https://github.com/python/cpython/blob/87e59ac11ee074b0dc1bc864c74fac0660b27f6e/Lib/idlelib/calltip.py)

Thanks to Dan Snider for the original report in msg332881 on issue #35196.


Example:

>>> def foo(s='a'*100):
pass

>>> print(get_argspec(foo))
(s='')

>>> def bar(s='a'*100):
"""doc-string"""
pass

>>> print(get_argspec(bar))
(s='a
aaa')
doc-string

I'm marking this as easy.

Whoever works on this should make sure to add a new test case for this bug.

[issue35642] _asynciomodule.c compiled in both pythoncore.vcxproj and _asyncio.vcxproj

[Gregory Szorc]

New submission from Gregory Szorc :

The _asynciomodule.c source file is compiled as part of both pythoncore.vcxproj 
(providing pythonXY.dll) and _asyncio.vcxproj (providing _asyncio.pyd).

PC\config.c doesn't reference PyInit__asyncio. I'm inclined to believe that 
_asynciomodule.c being built as part of pythoncore.vcxproj is a mistake.

If all goes according to plan, I will contribute my first CPython patch with a 
fix shortly...

[issue35638] Introduce fixed point locale aware format type for floating point numbers

[Eric V. Smith]

Eric V. Smith  added the comment:

I haven't looked at this closely yet, but you'll need to at least:
- add tests that the locale-aware formatting is happening
- support decimal
- make sure it works with complex (which it probably does, but needs a test)

And, I think we'll need to run this through python-ideas first. One thing I 
expect to come up there: why f and not g?

Again, I haven't looked through the code yet, or really even given any thought 
to determining if this is a sound idea.

[issue35644] venv doesn't do what it claims to do (apears not to work at all?)

[Ray Donnelly]

New submission from Ray Donnelly :

Happy New Year!

I'm not sure if this is a misunderstanding on my part, a docs bug or a code bug.

At https://docs.python.org/3/library/venv.html we see:

"The solution for this problem is to create a virtual environment, a 
self-contained directory tree that contains a Python installation for a 
particular version of Python, plus a number of additional packages"

and

"This will create the tutorial-env directory if it doesn’t exist, and also 
create directories inside it containing a copy of the Python interpreter, the 
standard library, and various supporting files."

However, when testing with 
https://www.python.org/ftp/python/3.7.2/python-3.7.2-amd64.exe I see no Python 
interpreter (nor DLL) in my venv directory:

```
python.exe -m venv %TEMP%\venv
%TEMP%\venv\Scripts\activate.bat
dir %TEMP%\venv
```

gives:

```
 Directory of C:\Users\RDONNE~1\AppData\Local\Temp\venv

02/01/2019  19:38  .
02/01/2019  19:38  ..
02/01/2019  19:38  Include
02/01/2019  19:38  Lib
02/01/2019  19:38   121 pyvenv.cfg
02/01/2019  19:38  Scripts
   1 File(s)121 bytes
   5 Dir(s)  912,281,780,224 bytes free
```

pyvenv.cfg contains:

```
home = C:\Users\rdonnelly\AppData\Local\Programs\Python\Python37
include-system-site-packages = false
version = 3.7.2
```

Further to this, after activating, I do not see the `venv` directory in 
`sys.path`:

```
python -c "import sys; print(sys.path)"
['',
 
'C:\\Users\\rdonnelly\\AppData\\Local\\Programs\\Python\\Python37\\python37.zip',
 'C:\\Users\\rdonnelly\\AppData\\Local\\Programs\\Python\\Python37\\DLLs',
 'C:\\Users\\rdonnelly\\AppData\\Local\\Programs\\Python\\Python37\\lib',
 'C:\\Users\\rdonnelly\\AppData\\Local\\Programs\\Python\\Python37',
 
'C:\\Users\\rdonnelly\\AppData\\Local\\Programs\\Python\\Python37\\lib\\site-packages']
```

>From past experience, the old `virtualenv` project would copy the interpreter 
>and DLL across.

Any help here would be appreciated!

[issue35644] venv doesn't do what it claims to do (apears not to work at all?)

[Ray Donnelly]

Ray Donnelly  added the comment:

Bit of an update to this, I'm re-opening it as there appears to be a regression 
from Python 3.7.1 to 3.7.2 for the case when there is no venvlauncher.exe 
present (i.e. when there are no python{w,}.exes in Lib\venv\scripts\nt). The 
old code of copying `sys.executable` is no longer run (on Windows only).

Currently Anaconda Distribution's venv is done this way. Should we change it to 
use the same method as official CPython Windows releases?

Here is a diff I think we need to apply for now, if you feel it is reasonable 
to make a PR then I'm happy to do so.

[issue35629] hang and/or leaked processes with multiprocessing.Pool(...).imap(...)

[Rémi Lapeyre]

Rémi Lapeyre  added the comment:

I believe that this is similar to https://bugs.python.org/issue35378 on which 
@pablogsal is working.

You were right, the issue steems from a refcount bug. Until the resolution you 
can avoid the issue by explictly keeping a reference on the pool:

>>> import multiprocessing
>>> d = multiprocessing.Pool(4)
>>> tuple(d.imap(print, (1, 2, 3)))
1
2
3
(None, None, None)
>>>
