[issue46005] [doc] replace 'distutils' examples with 'setuptools'

[Tal Einat]

Tal Einat  added the comment:

First, I think that it's good and useful to have full, well-maintained examples 
of how to build extension modules in the docs.

Second, until distutils is removed, I think we should keep the documentation 
for how to use it. Due to this, I don't think adding the "setuptools 
disclaimer" would be appropriate, since we shouldn't remove the section once 
the setuptools docs are updated.

It seems to me that we should:

1. Add a prominent note about distutils being deprecated and what that means: 
can one still use it, should one still use it, when is it planned to be 
removed, etc.

2. Add mention that 3rd-party tools are now the recommended way to build 
extensions. Include links to the sections in these libraries' docs explaining 
how to build extensions.

[issue45452] Support crash tolerance feature for gdbm module

[Gregory P. Smith]

Gregory P. Smith  added the comment:

The gdbm module's purpose is effectively one of just exposing the underlying C 
library APIs to Python as you said.  

Consider this a +1 in favor of exposing the new APIs in the Python gdbm module.

I'm not concerned about anyone wanting these in older Python versions. It 
really requires a combination of modern software in order to use.  Running on a 
recent kernel version, using a non-default fancy filesystem, and linking 
against a recent gdbm library.  So being a new feature in 3.11 makes sense.  
Anyone satisfying all of the above is highly likely to already also use a 
recent CPython.

If anyone _really_ wants it for older things, they can maintain backport on 
PyPI.

[issue46421] unittest ValueError when invoking as module

[Bader Zaidan]

New submission from Bader Zaidan :

When running a local unittest as a module (for example, `python -m unittest 
./tests/*.py`), the command fails with a ValueError. However, if we remove the 
local directory definition, and call it as `python -m unittest tests/*.py`, it 
runs without issue.

A GitHub pull request with a pull request will be sent promptly.

[issue46392] MessageIDHeader is too strict for message-id

[R. David Murray]

R. David Murray  added the comment:

Note that the parser does attempt to accept obsolete syntax (registering 
defects for it), so if there is a bug in the implementation of the obsolete 
syntax handling it should be fixed.  And yes, there have been other bugs with 
whitespace handling in the parser, unfortunately.

Examples would be most helpful, even if you don't write unit tests.  Most of 
the tests, by the way, are in test__header_value_parser (search for 
message_id).  There aren't very many, so more would be good.

[David Lord]

David Lord  added the comment:

I can reproduce this on Python 3.10. 
Actually, `input` and `getpass` both seem to have this behavior now. Please 
reopen it.

```python
import getpass

try:
getpass.getpass("in: ")
except:
pass

print("done")
```

```
$ python example.py
getpass: ^D done
$
```

Run this and press `Ctrl+D` or `Ctrl+C`. The shell prompt appears on the same 
line rather than the next line.

[issue46419] Incomplete Comparison to C++ Methods

[Jorgen Harmse]

New submission from Jorgen Harmse :

The description of classes mentions twice that methods are like C++ virtual 
member functions, but the truth is a bit stranger.

Even __init__ seems to act like a virtual function, so there is no guarantee 
that the base-class part of a derived-class instance is properly constructed.

Even if the base class __init__ is called, it may behave erratically. The 
object is already considered to belong to the derived class, so any method 
calls will resolve to the derived class. In C++, the run-time type inside any 
constructor or destructor always matches the compile-time type. Derived-class 
members are not called because those methods would attempt to use parts of the 
object that haven't been constructed yet or have already been destructed. 
Python takes no such precautions, and programmers should be warned accordingly. 
(I think the solution is to be very careful of calling any other method from 
__init__.)

[issue46412] PyQT6 projects crashes with python 3.10

[Fernando Pérez Gómez]

Fernando Pérez Gómez  added the comment:

I have to perform several tests to provide a detailed report, check other
third party libraries, mysql connector for example, and send it to you.
There are several things that don't work with Qt libs (the one that works
best is PyQt6). When I finish the tests and have the report, I'll send it
to you. In the meantime I suggest you search for pyqt6 + python3.10 on the
web. There are plenty of complaints on all platforms (Windows, Mac and
Linux). My system is Manjaro Linux , kernel version 5.15-2 , the PyQt6
version installed is 6.22.3 . So far I have verified that it is not the
fault of the IDE and that it does not install the plugins via pip . Of
course I will report the same to River Bank Computing. Sorry I can't be
more specific at the moment, because python has been updated on my system
recently.
Thanks for your patience , I 'll send you a full report in a couple of days
. that takes work

[issue46418] Simplify `MODULE` variable in `test_enum.py`

[Nikita Sobolev]

New submission from Nikita Sobolev :

Right now `MODULE` in Lib/test/test_enum.py is defined as:

```python
MODULE = ('test.test_enum', '__main__')[__name__=='__main__'] 
```

I dived into history and did not find any reasoning why it should not be just 
`__name__`. (But, I might had missed it: the first usage of it is dated back to 
2016)

This came up in https://github.com/python/cpython/pull/30641

So, I think it is a good idea to simplify it like this:

```python
MODULE = __name__
```

Probably, this won't cause any more confusion in the future :)

I am not going to change all `MODULE` usages to `__name__` to keep the diff as 
minimal as possible.

[issue45691] Partial moving of core objects to interpreter state is incorrect at best, unsafe at worse.

[STINNER Victor]

STINNER Victor  added the comment:

> `sys.float_info.n_unnamed_fields` causes a memory violation if the 
> per-interpreter allocated 0 held by sys.float_info.n_unnamed_fields is freed.
> If it is not freed, then `sys.float_info.n_unnamed_fields is 0` is False, 
> meaning that there are two zeros present.

Python 3.9 and 3.10 are concerned by this issue: integer singletons are 
per-interpreter since Python 3.9.

Should Python 3.9 and 3.10 be fixed? "x is 0" is recommended and should be 
used. For example, the compiler emits a SyntaxWarning:

$ python3.9
>>> x=0
>>> x is 0
:1: SyntaxWarning: "is" with a literal. Did you mean "=="?
True

I propose to only fix the main branch and so close the issue.

[issue46417] [subinterpreters] Clear static types in Py_Finalize()

[STINNER Victor]

New submission from STINNER Victor :

Converting static types to heap types is a work-in-progress:

* bpo-40077: "Convert static types to heap types: use PyType_FromSpec()"
* At December 29, 2020, 43% (89/206) of types are declared as heap types on a 
total of 206 types. For comparison, in Python 3.8, only 9% (15/172) of types 
were declared as heap types: 74 types have been converted in the meanwhile.
* https://vstinner.github.io/isolate-subinterpreters.html

Static types are still causing issues with Py_Initialize() / Py_Finalize() is 
called multiple times in the same process, which is a supported use case for 
embedded Python. See bpo-45691 "Partial moving of core objects to interpreter 
state is incorrect at best, unsafe at worse" for a recent example with 
sys.float_info where sys.float_info.n_unnamed_fields holds a reference to a 
Python object.

In june 2020, I wrote GH-20763 to clear static types at exit. But I abandoned 
my attempt because of bugs. Copy of my 
https://bugs.python.org/issue1635741#msg371119 message:

"""
I wrote PR 20763 to "finalize" static types in Py_Finalize(). It mostly works, 
but "./Programs/_testembed test_forced_io_encoding" crash. This program calls 
Py_Initialize() and Py_Finalize() multiple times in a loop.

It doesn't look to be safe to clear static types. Many functions rely on the 
fact that static types are "always there" and are never finalized. Also, only a 
few static types are cleared by my PR: many static types are left unchanged. 
For example, static types of the _io module.

It seems like a safer approach is to continue the work on bpo-40077: "Convert 
static types to PyType_FromSpec()".
"""

I propose a "best effort" approach: only clear a static type if it is no longer 
used. For example, check its reference count and its __subclasses__() method.

Pure enums have a few more dir() entries now; mixed enums now show all

[issue46414] Add typing.reveal_type

[Jelle Zijlstra]

New submission from Jelle Zijlstra :

The `reveal_type()` primitive is injected by type checkers into the builtins. 
When the type checker sees a call, it prints the inferred type of the argument.

This has been implemented across all type checkers, but adding an 
implementation to `typing` would help document the behavior and make it more 
discoverable for users. Also, it means code with `reveal_type()` calls can run 
without runtime errors, useful if you want to run your tests at the same time 
as you're debugging a typing issue.

The runtime implementation can be very simple:

def reveal_type(obj: _T, /) -> _T:
print("Runtime type is", type(obj))
return obj


reveal_type() is supported by all type checkers that I'm aware of (docs include 
https://google.github.io/pytype/faq.html#can-i-find-out-what-pytype-thinks-the-type-of-my-expression-is
 for pytype and 
https://mypy.readthedocs.io/en/stable/common_issues.html#reveal-type for mypy).

One area of divergence is the return value. Pyright returns the inferred type 
of the expression as a string (and uses that in its test suite for testing type 
inference). Mypy returns the argument, which has the advantage that you can 
insert `reveal_type()` in the middle of an expression without having to put it 
on its own line. Also, the Pyright behavior cannot sensibly be implemented at 
runtime. Therefore, I suggest using Mypy's behavior for `typing.reveal_type`.

This is most likely a problem with PyQt6. Please ask that project first (with a 
clearer description of what goes wrong and on which platforms).

[issue46413] `__or__` is not covered for `_GenericAlias` and `_SpecialGenericAlias` in `typing`

[Nikita Sobolev]

New submission from Nikita Sobolev :

Today I've noticed that these two methods are not covered: 
https://github.com/python/cpython/blame/16901c0482734dbd389b09ca3edfcf3e22faeed7/Lib/typing.py#L1028-L1032

- `typing._GenericAlias.__or__`
- `typing._GenericAlias.__ror__`

Later, I've realized that these two methods are not covered as well: 
https://github.com/python/cpython/blame/16901c0482734dbd389b09ca3edfcf3e22faeed7/Lib/typing.py#L1149-L1153

- `typing._SpecialGenericAlias.__or__`
- `typing._SpecialGenericAlias.__ror__`

My test plan is:
1. Cover regular `_GenericAlias` with `|` operation
2. Cover some `_SpecialGeneriAlias` instances like `Sized` and `Hashable`
3. Cover `Callable` and `Tuple` types, because they are a special-cased 
subtypes of `_SpecialGeneriAlias`

PR is on its way.

[issue22039] PyObject_SetAttr doesn't mention value = NULL

[Petr Viktorin]

Petr Viktorin  added the comment:

This cannot be changed in 3.x, since the PyObject_DelAttr macro calls 
PyObject_SetAttr(..., NULL), and the macro is expanded in all extensions that 
use the stable ABI.
(Technically, it would be possible to add a PyObject_SetAttr *macro* that would 
warn/fail, while keeping the PyObject_SetAttr *function* untouched, but that 
would be a pain to test/maintain.) 

The wording could be clarified to something like: "This behaviour is deprecated 
in favour of using PyObject_DelAttr(), but there are currently no plans to 
remove it."
