[issue46396] Typing: test invalid usages of `Concatenate`

[Nikita Sobolev]

Nikita Sobolev  added the comment:

> So maybe that code could just be removed?

I see this trend in typing.py :)

I think it makes sense to make all new types (I still consider `ParamSpec` and 
`Concatenate` as new, desipte the fact they are already released in 3.10) as 
flexible as possible.

I will change my PR.

[issue45995] string formatting: normalize negative zero

[Mark Dickinson]

Mark Dickinson  added the comment:

[John]

> Mark, would you give it a review this month?

Apologies; my holiday-break free time was nobbled from unexpected quarters. I 
can't promise to find time this month, but I can promise to try. I did at least 
skim through the PR, and while there are still likely some iterations needed 
I'm satisfied that this is technically feasible.

But I'm afraid that's the easy part. If this is to go in, the other problem we 
still have to solve is achieving some consensus among the core developers that 
this is worth doing. Right now, judging by comments on this issue, I think I'm 
the only core dev who thinks this is a good idea; others are lukewarm at best, 
and I'm not willing to unilaterally approve and merge these changes without 
something closer to a consensus. There are a couple of ways forward here:

- Post the proposal on python-ideas to get wider visibility and feedback. If 
everyone agrees this is a great idea (from experience, this seems an unlikely 
outcome), then we can go ahead and merge. Otherwise we'd likely need a PEP to 
move forward.

- Bypass the python-ideas step, write the PEP, discuss in the appropriate 
forums, and then submit to the SC for approval / rejection.

- Convince Eric Smith. :-) With apologies to Eric for singling him out: Eric 
could reasonably be described as the steward/maintainer of the formatting 
machinery, so if he's persuaded, that's good enough for me.

The fact that you've already created a working implementation so that people 
can experiment is a bonus when it comes to trying to sell this to others.

I don't have the bandwidth to write a PEP, but I would be happy to act as PEP 
sponsor.

[issue46470] `_remove_dups_flatten` in `typing.py` contains dead branch

[Nikita Sobolev]

New submission from Nikita Sobolev :

Here's how `_remove_dups_flatten` is defined right now:

```
def _remove_dups_flatten(parameters):
"""An internal helper for Union creation and substitution: flatten Unions
among parameters, then remove duplicates.
"""
# Flatten out Union[Union[...], ...].
params = []
for p in parameters:
if isinstance(p, (_UnionGenericAlias, types.UnionType)):
params.extend(p.__args__)
elif isinstance(p, tuple) and len(p) > 0 and p[0] is Union:
params.extend(p[1:])
else:
params.append(p)

return tuple(_deduplicate(params))
```

Source: 
https://github.com/python/cpython/blob/38afeb1a336f0451c0db86df567ef726f49f6438/Lib/typing.py#L274

It is only used in `def Union():`, source: 
https://github.com/python/cpython/blob/38afeb1a336f0451c0db86df567ef726f49f6438/Lib/typing.py#L522-L523

```
parameters = tuple(_type_check(p, msg) for p in parameters)
parameters = _remove_dups_flatten(parameters)
```

But, notice that `_remove_dups_flatten` contains this branch: `elif 
isinstance(p, tuple) and len(p) > 0 and p[0] is Union:`.

It is never executed, removing it does not change `test_typing` / `test_types` 
results. And it is reasonable: `_type_check` ensures that `parameters` can only 
contain types, not `tuple`s.

Proof:

```
>>> from typing import Union, get_type_hints

>>> Union[int, (Union, str, bool)]
# TypeError: Union[arg, ...]: each arg must be a type. Got (typing.Union, 
, ).

>>> class Some:
...x: 'Union[int, (Union, str, bool)]'
... 
>>> get_type_hints(Some)
# TypeError: Union[arg, ...]: each arg must be a type. Got (typing.Union, 
, ).
```

Since it is pretty old, I guess the internal API has changed significantly and 
it is not needed anymore.

I am going to send a PR to remove it.

[issue46471] use global singletons for single byte bytes objects in deepfreeze

[Kumar Aditya]

New submission from Kumar Aditya :

By using global singletons for single byte bytes objects in deepfreeze, there 
is no need to generate c code for it so it reduces the size of generated c file 
and reduces memory use of the objects when they are allocated on the heap as 
now they are statically allocated and they are already immortal.

[issue46472] A option that choose between single quote and double quote in shlex.quote

[I_love_study]

New submission from I_love_study <1450069...@qq.com>:

shlex.quote always use single quote
but in some shell (like Cmd on Windows), single quote cannot be recognized as a 
shell-escaped string, only double quote can.
So I think a option that can choose between single quote and double quote is 
better

[issue46396] Typing: test invalid usages of `Concatenate`

Let's change typing_extensions.py too in the same way.

Speaking of typing-extensions, it'd be great if someone could review

[issue46473] importlib.metadata does not honor .egg-link files

[Ben]

New submission from Ben :

When installing a package using --editable, pip creates a .egg-link file in 
your site-packages dir that points to the .egg-info metadata that by default 
exists along side the source that it was installed from. This worked just fine 
with the older pkg_resources package. However, the newer importlib.metadata 
does not seem to be aware of .egg-link files at all. The only solution is to 
include the source dir that contains the .egg-info metadata into your 
PYTHONPATH, which sort of defeats the purpose of having the .egg-link pointer 
in the first place.

[issue46473] importlib.metadata does not honor .egg-link files

[Éric Araujo]

Éric Araujo  added the comment:

It would make sense if importlib only supported official specs.
For editable/develop installs, it is https://www.python.org/dev/peps/pep-0660/ 
which does not mention egg (not egg-link nor egg-info, long since replaced by 
dist-info).

Are you using latest pip, and pyproject.toml?  I would expect pip to follow the 
PEP too.

[issue46473] importlib.metadata does not honor .egg-link files

[Ben]

Ben  added the comment:

yes, the latest version of pip creates an .egg-info metadata dir at the level 
of the package src dir and .egg-link and easy-install.pth stubs in the 
site-packages dir (the contents of which are paths to the package src dir). The 
intent is that these links would be followed to find the necessary metadata for 
the package. However, importlib.metadata does not follow either one of these 
links. These links are what makes editable installs possible, so I'm not sure 
how they can be ignored all together, unless there's some different facility 
that provides this functionality.

[issue1635741] Py_Finalize() doesn't clear all Python objects at exit

[STINNER Victor]

STINNER Victor  added the comment:

In bpo-46417, I pushed a change to call _PyDebug_PrintTotalRefs() after 
destroying the interpreter. I backported locally this change to other Python 
versions to compare the progress on old Python versions:

./python -I -X showrefcount -c pass command:

* Python 3.7: [22636 refs, 7453 blocks]
* Python 3.8: [18082 refs, 5867 blocks]
* Python 3.9: [17786 refs, 5766 blocks]
* Python 3.10: [10725 refs, 3978 blocks]
* current main branch: [2957 refs, 1240 blocks]

Yeah, main is way better than Python 3.10! I pushed many changes in 
bpo-46417 to clear most static types, it helps a lot!

[issue46417] Clear static types in Py_Finalize() for embedded Python

[STINNER Victor]

STINNER Victor  added the comment:

Attached cannot_deallocate.patch explains why some static types cannot be 
deallocated. It lists (static) types which are not cleard properly at Python 
exit.

Simplest example:
---
$ ./python -c pass
Cannot clear type 'object': it still has subclasses
* EncodingMap
* fieldnameiterator
* formatteriterator
* BaseException
* _io._IOBase
* _io._BytesIOBuffer
* _io.IncrementalNewlineDecoder
---

More complete example:
---
$ ./python setup.py build
running build
(...)
Cannot clear type 'types.GenericAlias': it still has subclasses
* _CallableGenericAlias
Cannot clear type 'tuple': it still has subclasses
* datetime.IsoCalendarDate
* DecimalTuple
Cannot clear type 'staticmethod': it still has subclasses

[issue46474] Inefficient regular expression complexity in EntryPoint.pattern

[Jason R. Coombs]

New submission from Jason R. Coombs :

Originally reported to the Python Security Response Team, the 
EntryPoint.pattern demonstrates a potential 
[ReDoS](https://owasp.org/www-community/attacks/Regular_expression_Denial_of_Service_).

The issue has been patched and fix released with importlib_metadata 4.10.1. 
Let's get that fix incorporated into Python as well.

[issue46474] Inefficient regular expression complexity in EntryPoint.pattern

[Jason R. Coombs]

Jason R. Coombs  added the comment:

Because I want this security issue to be back-portable to older Pythons, I'll 
first apply importlib_metadata 4.10.0 and then apply the change from 4.10.1 
separately.

[issue46454] '0 -> /dev/null' is lost

[Eryk Sun]

Eryk Sun  added the comment:

> If some one closes fd 0, then he reopens it. it will not be inherited.

In Windows, when a console process spawns a child console process without 
enabling handle inheritance -- e.g. subprocess.Popen(['python.exe']) -- the OS 
will manually duplicate (not inherit) the standard handles to the child. It 
doesn't matter in this case that a standard handle isn't inheritable. 

The latter also doesn't matter when any of the standard handles is overridden 
by a Popen() call in Windows -- e.g. subprocess.Popen(['python.exe'], 
stderr=DEVNULL). All of the standard handle values have to be overridden 
together. Popen() uses this as an opportunity to duplicate an inheritable 
handle for each that's not overridden, instead of just copying the handle value.

On the other hand, if subprocess.Popen() is called in Windows with handle 
inheritance enabled and without overriding the standard handles -- e.g. 
subprocess.Popen(['python.exe'], close_fds=False) -- then the standard handles 
should be inheritable. If any of the standard handles isn't inheritable, then 
at best the standard handle value in the child will be invalid or used by a 
handle for a kernel object type other than a file (e.g. process, event). By 
coincidence, however, a file open in the child could reuse the standard handle 
value, which can lead to buggy behavior.

[issue46431] Trouble subclassing ExceptionGroup

[Guido van Rossum]

Guido van Rossum  added the comment:

Is this a matter of adding some documentation showing how it should be done? 
Even if we don't want to encourage such subclassing, we do have APIs to support 
it, and I think we ought to show how to do it, given that you have to 
coordinate a bunch of things.

How feasible is it to improve the error? (If that error is what you always get 
when __init__ and __new__ don't agree, maybe that could be a separate, more 
general issue?)
