[issue45669] An 'ascii_alphanumerics' variable is missing in the 'strings' lib

2021-10-30 Thread Paolo Melchiorre 


Paolo Melchiorre  added the comment:

Thank you all for the feedback, also I have been using python for years and 
contributing to other python-based projects it is my first PR to Cpython and I 
don't know if my contribution to the discussion is foreseen.

It seems to me that adding this constant does not cause any damage in fact it 
is an easy victory. However, I try to clarify some doubts raised.

I proposed this new variable to simplify the code in a use case that occurs 
very often, not so much to save some characters.

I think every single new variable, constant and function needed a waiting 
period before being used in packages that support different versions of python 
(ex: f-string in Python 3.6) but can be used in the code of projects that use 
the latest version of python or in the python code itself.

The definition of the alphanumeric constant in the standard libraries I believe 
can help to have a clearly defined common variable[1], which could be used as a 
basis for alphabets containing additional symbols (ex: _- =)

[issue45625] Add support for top-level await

2021-10-30 Thread Fred 


Fred  added the comment:

No, I was not aware of that.

After I started Python by running "python3 -m asyncio" then it behaved as I 
expected it should behave by default.

But this seems to work only in the REPL. I would like to write Python scripts 
stored in files where I can easily await at the top level as in the example in 
my first post.

I read that to mean that the streams are file-like objects (or TextIOWrappers)

FWIW: I think it's best not bother and simply freeze the whole thing.

It's mostly char mappings which compress well and there's a benefit
in sharing these using mmap (which the OS does for you with static
C data).

I don’t know that longer is the right think to look at here, but rather more 
specific.  Unless I’m mistaken, a cookie for test.com is not read on

[issue45588] cached_method similar to cached_property to cache with classes

2021-10-30 Thread Éric Araujo 

Éric Araujo  added the comment:

The feature proposed here is not clear to me.

Is it about caching the method object on the instance to optimize the creation 
of the bound method, as the name suggests?  Or is it about caching the result 
of calling the method, which is consistent with the references to lru_cache and 
cachedproperty?

[issue45679] typing.Literal[True] is implicitly converted to typing.Literal[1]

2021-10-30 Thread Serhiy Storchaka 


Serhiy Storchaka  added the comment:

I agree. lru_cache(typed=True) itself should not look into iterable internals. 
It would be not only slow, but a change of semantic.

The simplest way to solve this issue is to remove caching of __getitem__(). The 
more sophisticated way is to move caching to lower level and apply it to a 
function with a var-positional parameter.

[issue45679] typing.Literal[True] is implicitly converted to typing.Literal[1]

2021-10-30 Thread Nikita Sobolev 


Nikita Sobolev  added the comment:

I see several ways of solving this:
1. Make `lru_cache(typed=True)` to look into iterable internals. This might be 
slow. And very slow for large iterables. Maybe even infinite for infinite ones
2. Adapt `Literal` / possibly other types to be treated differently. Because, 
most of the time, `Literal` take a small amount of args

I am going to send a PR with the second option.

[issue45679] typing.Literal[True] is implicitly converted to typing.Literal[1]

2021-10-30 Thread Nikita Sobolev 


Nikita Sobolev  added the comment:

This happens to all `lru_cache` calls, where we deal with container types.

Example:

```
from functools import lru_cache

@lru_cache(typed=True)
def test(arg):
return str(arg)

print(test((1, 'a')))  # (1, 'a')
print(test((True, 'a')))  # (1, 'a')
```

Moveover, this behavior is not tested in `test_functools`:

[issue45679] typing.Literal[True] is implicitly converted to typing.Literal[1]

2021-10-30 Thread Van Burgerberg 


New submission from Van Burgerberg :

When you create `Literal[1]` annotation and then create `Literal[True]` 
annotation, in the second case you will actually get `Literal[1]` instead. This 
is happening because `typing` performs caching of the outcome of parameterizing 
generics and `hash(True)` is equal to `hash(1)`. I think this behavior is 
incorrect and may lead to unexpected results.

Why is this inaccuracy important?
Consider the following example:

```python
from typing import Literal

SomeUsefulAlias = Literal[1, "abc"]

def func(arg: Literal[True, "abc"]):
if arg is not True:
arg.capitalize()
```

If we look at `func.__annotations__["arg"]`, we will see `Literal[1, 'abc']`. 
According to the new annotation, we can pass the value `1` to `func`, and this 
will lead to an attribute error, as you've already understood. Thus, proper 
runtime type checking cannot be performed.

[issue45669] An 'ascii_alphanumerics' variable is missing in the 'strings' lib

2021-10-30 Thread Serhiy Storchaka 


Serhiy Storchaka  added the comment:

I was also against this feature. My reasons:

1. There will be not much benefit. ascii_alphanumerics is too long, so there is 
no much saving of typing. There is larger chance of typo. You will be not able 
to use it for several years, until support of Python 3.10 be dropped, without 
making the code uglier.

2. What exactly should it include? In virtually all use cases in the stdlib and 
tests (except two tests) you need a set which contains ascii_letters, digits, 
and some other characters (usually "_", but sometimes more). Should "_" be 
included in ascii_alphanumerics? Whatever we choose, it will be less explicit 
than ascii_letters + digits and people will need to look in the documentations 
or make errors. And every reader of the code would have doubts.

[issue45669] An 'ascii_alphanumerics' variable is missing in the 'strings' lib

2021-10-30 Thread Dong-hee Na 


Dong-hee Na  added the comment:

@skip.montanaro

I agree with your concern, if authors want to use this constant,
they need to use the mentioned workaround to import it.
But we already have cases that add such constants if we considered them as 
useful constants.

So I think that the main concern of this issue is that how it will be useful.
In my case, if I should write the utility to generate random tokens for 
authentication in python, I always write a single trivial code to use 
ascii_alphanumerics, that's why I thought that this constant can be useful.
FYI We already have the same use case in official documentation[1] also.

But if other core devs also thought that this is not that commonly well-used 
case, I will change my mind to -1 since we can not support all ASCII 
variations(e.g ascii_number_special) and I agree with that point.

[issue32453] shutil.rmtree can have O(n^2) performance on large dirs

2021-10-30 Thread Niklas Hambüchen 

Niklas Hambüchen  added the comment:

A small update / summary so far:

>From here this developed into coreutils discussion:

#29921 O(n^2) performance of rm -r
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=29921

and finally a `linux-fsdevel` discussion:

O(n^2) deletion performance

https://lore.kernel.org/linux-fsdevel/5ca3808d-4eea-afec-75a6-2cc41f44b...@nh2.me/t/#u

Dave Chinner (xfs dev) suggests that on XFS there is no quadratic behaviour 
once  the problem is bound by seek-time of the spinning disk.

Somebody should try to confirm that it becomes linear in even larger tests, 
e.g. way larger than 21 minutes deletion time.

[issue45678] `functools.singledispatchmethod` is missing tests

2021-10-30 Thread Alex Waygood 


New submission from Alex Waygood :

`test_functools` includes a test to check that `functools.singledispatch` 
correctly wraps the attributes of the target function. However, there is no 
equivalent test for `functools.singledispatchmethod`. There should be, as this 
is done separately in the `__get__` method of `functools.singledispatchmethod`; 
it is a different mechanism to `functools.singledispatch`.

Additionally, `test_abstractmethod_register` tests that the return value of 
`singledispatchmethod.__get__` wraps the target function's 
`__isabstractmethod__` attribute. However, the `__isabstractmethod__` property 
of the `singledispatchmethod` class is untested.

[issue45669] An 'ascii_alphanumerics' variable is missing in the 'strings' lib

2021-10-30 Thread Skip Montanaro 


Skip Montanaro  added the comment:

I'll be the wet blanket here and say -1. This doesn't seem at all necessary. 81 
occurrences in ~3.5k PyPI packages? That's a hardly overwhelming endorsement. 
To top it off, since this can't be backported to 3.10 and earlier, it creates a 
needless (trivial) difference. Package authors who would like to use this but 
support earlier versions of Py3 will need to do something like this:

try:
from string import ascii_alphanumerics
except ImportError:
ascii_alphanumerics = string.ascii_letters + string.digits

They get no benefit from the addition. In fact, their code gets marginally 
harder to read.

[issue30082] hide command prompt when using subprocess.Popen with shell=False on Windows

2021-10-30 Thread Eryk Sun 


Eryk Sun  added the comment:

Here's an example test that calls WinAPI GetConsoleWindow() and 
IsWindowVisble() in a child process.

if mswindows:
try:
import ctypes
except ImportError:
ctypes = None

# added in Win32ProcessTestCase
def test_force_hide(self):
if ctypes:
script = textwrap.dedent(r'''
import sys, ctypes
GetConsoleWindow = ctypes.WinDLL('kernel32').GetConsoleWindow
IsWindowVisible = ctypes.WinDLL('user32').IsWindowVisible
sys.exit(IsWindowVisible(GetConsoleWindow()))
''')
else:
script = 'import sys; sys.exit(0)'
rc = subprocess.call([sys.executable, '-c', script], force_hide=True)
self.assertEqual(rc, 0)

This test will work reliably even if the user has Windows Terminal set as the 
default terminal (available with recent builds of Windows and Windows Terminal 
Preview). The proxy does not hand off to Windows Terminal if the STARTUPINFO 
wShowWindow is SW_HIDE or SW_SHOWMINIMIZED, or if the process is created with 
the CREATE_NO_WINDOW flag. In these cases, it just creates a system conhost.exe 
session.

[issue45671] str(CancelledError()) is empty

2021-10-30 Thread Serhiy Storchaka 


Serhiy Storchaka  added the comment:

Then you would get

>>> raise asyncio.CancelledError
Traceback (most recent call last):
  File "", line 1, in 
asyncio.exceptions.CancelledError: CancelledError

instead of

>>> raise asyncio.CancelledError
Traceback (most recent call last):
  File "", line 1, in 
asyncio.exceptions.CancelledError

Many existing code include both of exception name and message in the report 
about exception. Repeating the exception name as exception message will cause 
confusing.

You should follow common practice and print not just an exception object, but 
its name or repr. It will help in other cases, when the exception has non-empty 
message, but you do not know its type.
