[issue45971] calendar module issue

[Vedran Čačić]

Vedran Čačić  added the comment:

https://docs.python.org/3/library/calendar.html#module-calendar

The functions and classes defined in this module use an idealized calendar, the 
current Gregorian calendar extended indefinitely in both directions.

https://en.wikipedia.org/wiki/Proleptic_Gregorian_calendar

Even if we decide to change this, this is the thing locale should worry about: 
not every place adopted Gregorian Calendar at the same time, nor in the same 
way.

[issue45970] Py_NewInterpreter causes bogus fatal error along the failure path

[Jason Haslam]

New submission from Jason Haslam :

The failure cleanup of `Py_NewInterpreter` causes a bogus fatal error on the 
call to `PyThreadState_Delete`. The error is about deleting the current thread 
state. The saved thread state should be swapped back in *before* deleting the 
new thread state.

[issue45969] When uninstalling Python under Windows the "Scripts" folders should be removed from the PATH environment variable

[Steve Dower]

Steve Dower  added the comment:

Unless someone can find an authoring bug under Tools/msi, I don't think we can 
do anything about this. We rely on the built-in Windows support for adding and 
removing these variables, and if that's broken, we can't do anything with our 
current setup.

I really want to get us out of this addiction to cluttering up PATH with lots 
of different directories - it's bad for security/reliability/etc. of the system 
as a whole, and I don't like Python being the cause of issues here. But I 
haven't quite come up with the better design yet... 

Anyway, all that to say that I'm not in any rush to expand or seriously mess 
with the current PATH settings. If there's an authoring bug we can fix, great, 
but I don't think this one is on us in a way we can easily deal with.

[issue45582] Rewrite getpath.c in Python

[Steve Dower]

Steve Dower  added the comment:

It's done! Those were some of the hardest memory leaks I've had to track down, 
but it should be clear now.

As I mentioned in the commit message, this change attempts to preserve every 
known quirk. However, I think these ought to be streamlined across platforms to 
improve the code and/or startup performance.

But at least we know now that any changes in the future that require test 
changes are expected, and not the result of this change :)

[issue28533] Remove asyncore, asynchat and smtpd modules

[STINNER Victor]

STINNER Victor  added the comment:

> ansible-5.0.0

Reported upstream (it's a single file, used for tests):
https://github.com/ansible/ansible/issues/76452


> gevent-21.8.0

It's https://github.com/gevent/gevent/tree/master/src/greentest directory which 
contains subsets of the Python test suite. I guess that when they will copy the 
Python 3.11 tests, it will be fine.

* ansible-5.0.0
* cassandra-driver-3.25.0

[issue27946] elementtree calls PyDict_GetItem without owning a reference to the dict

[Irit Katriel]

Irit Katriel  added the comment:

This is a bug in elementtree - the caller should own a reference to the dict 
during the entire PyDict_GetItem call.

We won't add the refcount change you propose because it's not free and this is 
a hot function. 

The test in your patch doesn't fail for me (I tried on version 3.11 on a Mac). 
Are you still seeing the problem on version >= 3.9, or perhaps it was fixed in 
eaementtree by now?

Thank you Ali. It confirms my guess, but it is still not clear why we get a 
Tcl_Obj rather of None or empty string.

Please examine what is the output of the following code:

res = root.tk.call('wm', 'overrideredirect', root._w, True)
print([res.typename])
print([res.string])

If the first print crashes comment out it.

[issue45969] When uninstalling Python under Windows the "Scripts" folders should be removed from the PATH environment variable

[Luca]

New submission from Luca :

This issue is related to:
  https://bugs.python.org/issue3561
and:
  https://bugs.python.org/issue45968

When installing Python under Windows, if the "Add Python 3.x to PATH" option is 
flagged, the following two folders are added to the PATH environment variable:
  %USERPROFILE%\AppData\Local\Programs\Python\Python3x\
  %USERPROFILE%\AppData\Local\Programs\Python\Python3x\Scripts\

However when uninstalling Pyhton only the former folder is removed from the 
PATH environment variable, and not the latter one.

Moreover if also the following folder will be added to the PATH environment 
variable in future (see issue #45968):
  %USERPROFILE%\AppData\Roaming\Python\Python3x\Scripts\
then the same would apply to it.

[issue45957] _tkinter.TclError: expected boolean value but got ""

[Ali Amin-Nejad]

Ali Amin-Nejad  added the comment:

@serhiy.storchaka I tried that command, the returned value is not an empty 
string, it is an object of type . However including 
that line in my script immediately after creating the `root` object actually 
fixes the problem - no more error and the button appears and is responsive.

@ned.deily I am on tkinter 8.6.11. The output from the second command is:

```
/Users/ali/miniconda3/envs/bitfount/lib/python3.8/lib-dynload/_tkinter.cpython-38-darwin.so:
@rpath/libtcl8.6.dylib (compatibility version 8.6.0, current version 
8.6.11)
@rpath/libtk8.6.dylib (compatibility version 8.6.0, current version 
8.6.11)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current 
version 1213.0.0)
```

I have just tried the same script in a separate python 3.9 environment with 
python 3.9.6 and tkinter 8.6.10 and the error is not there so it seems like it 
is introduced in 8.6.11. Happy to try on 8.6.12 but I'm not sure how to upgrade 
to it.

[issue45957] _tkinter.TclError: expected boolean value but got ""

[Ned Deily]

Ned Deily  added the comment:

I am not able to reproduce this failure with various macOS Pythons from 
python.org that are built with either Tk 8.6.8 or 8.6.12. Perhaps it's an issue 
with the Tk provided with your Miniconda Python?  Besides answering Serhiy's 
question, it would be helpful to know the exact patch level of Tk that is being 
used and also the path to the Tk library.

The output from

/path/to/your/python -m test.pythoninfo

and

otool -L $(/path/to/your/python -c "import _tkinter;print(_tkinter.__file__)")

will give those answers.

[issue45920] make doctest fails

[Ned Deily]

Ned Deily  added the comment:

> So I guess the only way to actually get make doctest to work is if the 
> virtual env uses the version of python in main. Is there anyway to do that?

By default, the Doc/Makefile "venv" target uses the first "python3" it finds on 
your shell PATH to build the venv and sphinx. Either arrange for "python3" to 
point at a Python of the same release family on your PATH or you can use the 
PYTHON= command line argument to "make venv" to specify the path to the 
interpreter, for example:

cd cpython
./configure && make
cd Doc
make clean venv doctest PYTHON=../python
  [...]
  Doctest summary

[issue45897] Frozen dataclasses with slots raise TypeError

[Alex Waygood]

Alex Waygood  added the comment:

You get the same error if you subclass a frozen dataclass, then try to set an 
attribute that is not one of the superclass's __slots__:

```
>>> @dataclass(slots=True, frozen=True)
... class Point:
... x: int
... y: int
... 
... 
>>> class Subclass(Point): pass
... 
>>> s = Subclass(1, 2)
>>> s.z = 5
Traceback (most recent call last):
  File "", line 1, in 
s.z = 5
  File "", line 7, in __setattr__
TypeError: super(type, obj): obj must be an instance or subtype of type
```

[issue45966] Error in Multiplication

[Eric V. Smith]

Eric V. Smith  added the comment:

This isn't a bug, it's a function of the IEEE-754 double precision floating 
point type that python uses. See: 
https://docs.python.org/3/tutorial/floatingpoint.html

You might want to consider the decimal module, although that will also have 
limitations.

[issue45966] Error in Multiplication

[Mukesh]

New submission from Mukesh :

I've tried various methods to multiply some numbers but every time I get an 
unsatisfying result when I try to evaluate 48*1.2 or 41*1.2 or 51*1.4 etc. For 
example if I run

import math
NUM3 = eval(input("Your Input: "))
print(NUM3)

Output:
Your Input: 51*1.4
71.39

Now it should give me a straight 71.4 but instead it's giving 71.39

It's not an issue with the version of python that I'm using cause I've already 
tried it on various versions.

[issue45965] fileinput.input(path, inplace=True) crashes for valid filename with 252-255 characters

[Jamil Raichouni]

New submission from Jamil Raichouni :

import fileinput
from pathlib import Path
path = Path(252 * "x")
path.write_text("")
for line in fileinput.input(path, inplace=True):
pass

raises an

OSError: [Errno 63] File name too long

for perfectly valid (yes, quite long) file names.

Reason:

Internally the fileinput library creates a backup file when we pass 
'inplace=True' to fileinput.input() and that backup file gets a file name that 
is longer than the name for the file of interest.

Enhancement idea:

Work with a backup file name that is sth like GUID.bak or remove some chars 
from the original file name.

Hint:

vim /path/to/my/file creates a .swp file and can handle very long file names 
with 252-255 chars.

[issue45476] [C API] PEP 674: Disallow using macros as l-value

[STINNER Victor]

STINNER Victor  added the comment:

> pysha3-1.0.2

This module must not be used on Python 3.6 and newer which has a built-in 
support for SHA-3 hash functions. Example:

$ python3.6
Python 3.6.15 (default, Sep  5 2021, 00:00:00) 
>>> import hashlib
>>> h=hashlib.new('sha3_224'); h.update(b'hello'); print(h.hexdigest())
b87f88c72702fff1748e58b87e9141a42c0dbedc29a78cb0d4a5cd81

By the way, building pysha3 on Python 3.11 now fails with:

Modules/_sha3/backport.inc:78:10: fatal error: pystrhex.h: No such file or 
directory

The pystrhex.h header file has been removed in Python 3.11 by bpo-45434. But I 
don't think that it's worth it trying to port it to Python 3.11, if the module 
must not be used on Python 3.6 and newer.

Environment markers can be used to skip the pysha3 dependency on Python 3.6 on 
newer.

Example: "pysha3; python_version < '3.6'"

[issue45476] [C API] PEP 674: Disallow using macros as l-value

[STINNER Victor]

STINNER Victor  added the comment:

> frozendict-2.1.1

If I understand correctly, this module is compatible with the PEP 674, it only 
has to copy Python 3.11 header files once Python 3.11 is released, to port the 
project to Python 3.11.

Incompatable code is not part of the "frozendict" implementation, but only in 
copies of the Python header files (Python 3.6, 3.7, 3.8, 3.9 and 3.10). For 
example, it contains the frozendict/src/3_10/cpython_src/Include/object.h 
header: copy of CPython Include/object.h file.

Source code: https://github.com/Marco-Sulla/python-frozendict

[issue45963] Embed interpreter frame in generator.

[Mark Shannon]

New submission from Mark Shannon :

Currently, the InterpreterFrame for a generator is allocated on the heap 
separately from the generator.
This means that 2 allocations are needed to create a generator, and an extra 
indirection is needed to get from the generator to the frame.

By embedding the frame in the generator, we only need one alloaction, we save 
an indirection *and* the code gets simpler: transferring the frame from 
generator to frame object is just a single memcpy.

[issue45957] _tkinter.TclError: expected boolean value but got ""

[Serhiy Storchaka]

Serhiy Storchaka  added the comment:

What is the result of

   root.tk.call('wm', 'overrideredirect', root._w, True)

?

Is it not an empty string?

[issue45961] [doc] Missing documentation for wait_for module

[Alex]

New submission from Alex :

I wondering why there is no documentation for the synchronous module "wait_for":

site-packages/wait_for/__init__.py

It's just missing or there are some reason? I didn't see any deprecation info 
about this module.

[Sascha Hesse]

New submission from Sascha Hesse :

Given a docker container on raspbian 10.11
based on bullseye:

docker run --rm -it --entrypoint sh python:3.10-slim

time.time() fails with error

# python

>>> import time
>>> time.time()
Traceback (most recent call last):
  File "", line 1, in 
PermissionError: [Errno 1] Operation not permitted

based on buster:

docker run --rm -it --entrypoint sh python:3.10-slim-buster

works as expected
