[issue42238] Deprecate suspicious.py?

[Julien Palard]

Julien Palard  added the comment:

Good idea Ned!

So proposed plan:

- Drop it from docs build and the CI to avoid time loss.
- Add it as a step of PEP 101, for a few release, for good measures
- I'll check it from time to time between releases, just to ensure it does not 
accumulate tons of things to do on the the release day.

If during a few release, we notice this tool is no loger usefull we'll be able 
to drop it.

If we spot some errors that can be migrated to the rstlint.py we'll do.

If this tool is in fact usefull, we'll have to think about it again.

[issue42195] Inconsistent __args__ between typing.Callable and collections.abc.Callable

In that case I prefer ((int, int), str), in case we ever end up needing to add 
additional parameters to Callable. I propose we first fix

[issue42102] Make builtins.callable "generic"

[Guido van Rossum]

Guido van Rossum  added the comment:

I'd like to pursue this for real; other issues for callable have popped up, 
https://bugs.python.org/issue42195 and https://bugs.python.org/issue40494 
(https://bugs.python.org/issue40398 is also related but already fixed).

>From 42195 I learn that __args__ ought to be hashable. I would prefer it to 
>still be structured, e.g. callable[[int, str], float].__args__ should be 
>((int, str), float).

This means we have to change typing.Callable and collections.abc.Callable as 
well (the latter may share code with builtins.callable, but typing.Callable 
should probably stay separate, but returning the same structure).

For performance reasons I'd prefer that the return value be hashable for both, 
but we've already shipped the workarounds [0,1,2] for 3.9.0 and will maintain 
that until 3.9 reaches EOL in any case.

Whether we return (int, int, str) or ((int, int), str) doesn't make much 
difference to me, the latter will require a trivial patch to [2] so please do 
whatever makes most sense upstream.


> Also, maybe we should make builtins.callable generic as well?

I like this idea :-)

[issue38506] Launcher for Windows (py.exe) may rank Python 3.xx (in the future) after 3.x

[Guido van Rossum]

Guido van Rossum  added the comment:

Hm, actually I think this needs to be backported to 3.8 and 3.9 (at least) 
since IIUC whichever release is installed last (or first?) overwrites "py.exe", 
so if "py.exe" came from e.g. 3.9, and 3.10 is present, we still want it to 
sort that correctly.

[issue36011] ssl - tls verify on Windows fails

[Tom Kent]

Tom Kent  added the comment:

Christian's message indicated that a workaround was possible by adding 
mozilla's certs to windows cert store. 

I'm sure there are sysadmins who will really hate this idea, but I've 
successfully implemented it in a windows docker image, and wanted to document 
here.

Powershell commands, requires OpenSSL to be installed on the system:
```
cd $env:USERPROFILE;
Invoke-WebRequest https://curl.haxx.se/ca/cacert.pem -OutFile 
$env:USERPROFILE\cacert.pem;
$plaintext_pw = 'PASSWORD';
$secure_pw = ConvertTo-SecureString $plaintext_pw -AsPlainText -Force;
& 'C:\Program Files\OpenSSL-Win64\bin\openssl.exe' pkcs12 -export -nokeys -out 
certs.pfx -in cacert.pem -passout pass:$plaintext_pw;
Import-PfxCertificate -Password $secure_pw  -CertStoreLocation 
Cert:\LocalMachine\Root -FilePath certs.pfx;
```

Once mozilla's store is imported into the microsoft trusted root store, python 
has everything it needs to access files directly.

[issue42280] The list of standard generic collections is incomplete

[jack1142]

jack1142  added the comment:

I was thinking that this could be the case but if I'm not mistaken, there's 
actually quite a lot of types in this list that aren't collections (awaitable, 
coroutine, iterable, iterator, generator, the async versions of those, 
callable, *hmm, are views collections?*, and the ones you mentioned), so I 
figured that listing *only* collections might have not been the intention when 
this was written. But listing all of the generics in Python would indeed be 
lengthy so it might make sense to limit it to collections nonetheless, I'm not 
really sure about it though.

Guido van Rossum  added the comment:

I think the difference between the two lists is that not every generic type is

If we apply that standard, I think the contextlib and re classes need to be

[issue42365] Python launcher: sort order in "Installed versions" off with 3.10

[Guido van Rossum]

New submission from Guido van Rossum :

I installed Python 3.10 on Windows and now the sort order of the versions 
printed by `py -0` is kind of weird:
```
Installed Pythons found by C:\WINDOWS\py.exe Launcher for Windows
 -3.9-64 *
 -3.8-64
 -3.7-64
 -3.6-64
 -3.5-64
 -3.10-64
```
I'm guessing we're going to have to parse the versions...

(I accidentally first reported this in 
https://github.com/brettcannon/python-launcher/issues/42.)

[issue6237] Build errors when using LDFLAGS="-Wl,--no-undefined"

[Irit Katriel]

Irit Katriel  added the comment:

Closing as out of date because it's from 14 years ago and the OP did not reply 
to Mark's ping. 

If this is an issue in Python 3 please open a new issue for that.

[issue42364] Typo in french doc translation

[Mathias MICHEL]

New submission from Mathias MICHEL :

In https://docs.python.org/fr/3/tutorial/inputoutput.html, § 7.1.3. Formatage 
de chaînes à la main

After the code block the sentence between () should  replace `donc` by `dont`:

(Remarquez que l'espace séparant les colonnes vient de la manière dont print() 
fonctionne : il ajoute toujours des espaces entre ses arguments.)

[issue39168] Generic type subscription is a huge toll on Python performance

[Guido van Rossum]

Guido van Rossum  added the comment:

@davidm

I don't see such a dramatic difference -- the generic version is a tad slower, 
but the difference is less than the variation between runs.

What platform are you using?  (I'm doing this on Windows.)

[issue13888] test_builtin failure when run after test_tk

[Terry J. Reedy]

Terry J. Reedy  added the comment:

tcl/tk 8.5, likely used in 2012 test, was by default compiled without thread 
support.  8.6, used now for sure on psf Windows and Macs installs and I believe 
on most *nixes, the default is *with* thread support.  Given the comments, this 
might affect results.

[issue39168] Generic type subscription is a huge toll on Python performance

[David Lord]

David Lord  added the comment:

Is this performance issue supposed to be fixed in 3.9? I'm still observing 
severe slowdown by inheriting from `Generic[T]`.

I'm currently adding typing to Werkzeug, where we define many custom data 
structures such as `MultiDict`. It would be ideal for these classes to be 
recognized as generic mappings. I remembered hearing about this performance 
issue somewhere, so I decided to test what happens.

Here's a minimal example without Werkzeug, the results in Werkzeug are similar 
or worse. I'd estimate each request creates about 10 of the various data 
structures, which are then accessed by user code, so I simulated that by 
creating and iterating a list of objects.

```python
class Test:
def __init__(self, value):
self.value = value

def main():
ts = [Test(x) for x in range(10)]
sum(t.value for t in ts)
```

```
$ python3.9 -m timeit -n 10 -s 'from example import main' 'main()'
10 loops, best of 5: 7.67 usec per loop
```

```python
import typing

V = typing.TypeVar("V")

class Test(typing.Generic[V]):
def __init__(self, value: V) -> None:
self.value = value

def main():
ts = [Test(x) for x in range(10)]
sum(t.value for t in ts)
```

```
$ python3.9 -m timeit -n 10 -s 'from example import main' 'main()'
10 loops, best of 5: 18.2 usec per loop
```

There is more than a 2x slowdown when using `Generic`. The timings (7 vs 18 
usec) are the same across Python 3.6, 3.7, 3.8, and 3.9. It seems that 3.9 does 
not fix the performance issue.

Since we currently support Python 3.6+, I probably won't be able to use 
generics anyway due to the performance in those versions, but I wanted to make 
sure I'm not missing something with 3.9.

[issue16801] Preserve original representation for integers / floats in docstrings

[Batuhan Taskaya]

Batuhan Taskaya  added the comment:

I'm very late to join this thread, but since the Constant() node has now a kind 
field, we can possibly add this (though I'm not saying we should, depending on 
whether still this would be a nice addition to clinic docstrings.)

2 options that I can think off:
- Introduce a couple of new tokens (BIN_NUMBER, OCT_NUMBER, HEX_NUMBER). 
- Add a new field to the tok_state struct (like const char* number_type) and 
when constructing the Constant node in the _PyPegen_number_token, add that 
number_type as the kind field of the constant.

In case of anyone wondering, the latter would be a +20 lines addition (no 
changes on the grammar / tokens, just a couple of new lines into the tokenizer 
and the _PyPegen_number_token.)

[issue38495] print built-in function docs bug

[Julien Palard]

Julien Palard  added the comment:

Hi!

Thanks Alex for reporting, and everyone involved.

This has been fixed in python-docs-theme, so it's fixed for >=3.8. As 3.7 is in 
security-only (and embeds python-docs-theme), better not touch it.

Bests.

[issue42345] Equality of typing.Literal depends on the order of arguments

[Ken Jin]

Ken Jin  added the comment:

@Guido and @Ivan,

Should Literals de-duplicate values in its __args__ similar to Union? PEP 586 
states that:
> Literal[v1, v2, v3] is equivalent to Union[Literal[v1], Literal[v2], 
> Literal[v3]]

Naturally, a Union de-duplicates values, so I was wondering if Literal should 
follow.

[issue42363] I think it will be better to output self._state for debugging

[Jim Lin]

New submission from Jim Lin :

I think the exception "raise ValueError("Pool not running")" is not easy for a 
programmer to quickly know the problem of their code.

Therefore, I add the value of self._state when throwing the ValueError.

[issue42362] Switch to clang as default compiler in build-installer.py

[Ronald Oussoren]

New submission from Ronald Oussoren :

build-installer.py still defaults to gcc as the default compiler, even though 
clang has been the system compiler for ages (and gcc is an alias in anything 
remotely recent).

PR is forthcoming

[issue42361] Use Tcl/Tk 8.6.10 in build-installer.py when building on recent macOS

[Ronald Oussoren]

New submission from Ronald Oussoren :

As discussed before we want to switch to Tcl/Tk 8.6.10 when building the 
installer on a recent version of macOS. The build on macOS 10.9 should continue 
to use 8.6.8 due to build issues.

PR is forthcoming (currently running tests)

[issue42328] ttk style.map function incorrectly handles the default state for element options.

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

Thank you for your examples Pat. Now it looks clearer to me.

Semantically this data in Tk is a sequence of pairs: states (which can be a 
single word or several words or empty) and default value.

>>> from tkinter import ttk
>>> style = ttk.Style()
>>> style.theme_use('clam')
>>> style.tk.eval(f'{style._name} map TCombobox -fieldbackground')
'{readonly focus} #4a6984 readonly #dcdad5'
>>> style.tk.eval(f'{style._name} map TNotebook.Tab -background')
'selected #dcdad5 {} #bab5ab'

Internally states represented in Tk as the StateSpec object. When automatically 
convert to Python it became the Tcl_Obj object with typename 'StateSpec'. 
Without postprocessing.

>>> style.tk.call(style._name, 'map', 'TCombobox', '-fieldbackground')
(, '#4a6984', , '#dcdad5')
>>> style.tk.call(style._name, 'map', 'TNotebook.Tab', '-background')
(, '#dcdad5', , '#bab5ab')

Style.map() does postprocessing. It converts a sequence (with even items 
number) to a list of tuples. The last item of a tuple is the default value, and 
the rest are items of the StateSpec object.

>>> style.map('TCombobox', 'fieldbackground')
[('readonly', 'focus', '#4a6984'), ('readonly', '#dcdad5')]
>>> style.map('TNotebook.Tab', 'background')
[('selected', '#dcdad5'), ('#bab5ab',)]

But when set tkinter.wantobjects = 0 before running this example the result 
will be different, because StateSpec objects will be automatically represented 
as strings (it matches the behavior of initial versions of Tkinter):

>>> style.tk.call(style._name, 'map', 'TCombobox', '-fieldbackground')
'{readonly focus} #4a6984 readonly #dcdad5'
>>> style.tk.call(style._name, 'map', 'TNotebook.Tab', '-background')
'selected #dcdad5 {} #bab5ab'
>>> style.map('TCombobox', 'fieldbackground')
[('readonly focus', '#4a6984'), ('readonly', '#dcdad5')]
>>> style.map('TNotebook.Tab', 'background')
[('selected', '#dcdad5'), ('', '#bab5ab')]

The main problem is in representing an empty StateSpec. As every string in 
Python contains an empty string, {} can represent an empty sequence and a 
sequence containing single empty string. In Python, it can be no items before 
default value (like in ('#bab5ab',)) or a single item containing an empty 
string (like in ('', '#bab5ab')).

The former representation (an empty sequence) is default for the style.map() 
output, but it is rejected as the style.map() input (see state[0] in 
_mapdict_values). There are two ways to fix it: either change the output of 
style.map() (what PR 23241 does) or change the validation of the input. I think 
that the latter solution can be backported, but the former can be used only in 
the future Python version.
