py39-salt, missing contextvars dependency?

G

I upgraded my sysutils/py-salt package to version 3006.1_1 (currently running 13.1-RELEASE with "latest" pkg sources). When trying to run a state from a minion the call crashes with various error messages. The line I finally found is:
Code: 
pkg_resources.DistributionNotFound: The 'contextvars' distribution was not found and is required by salt
The error appears on an upgraded version and on a fresh install of salt.
After running
Code: 
pkg install py39-pip
pip install contextvars
# not nice, I know. But for debugging purposes
the states I called worked flawlessly again.

How can I help to improve this behavior? Thanks for your response ;)
 
That contextvars should be included with Python 3.8 and above.

Code: 
dice@molly:~ % python3.9 -m contextvars
dice@molly:~ %
 
Hmm, interesting. I'm investigating further.

Using a freshly created jail I install sysutils/py-salt and try to salt-call state.apply a state from my salt master.
Code: 
# "quarterly" pkg sources
root@testjail:~ # pkg info py39-salt
py39-salt-3005.1_2
Name           : py39-salt
Version        : 3005.1_2
Installed on   : Mon Jul  3 09:31:32 2023 UTC
Origin         : sysutils/py-salt

# works fine ;)
I then changed the pkg sources to "latest" and did a pkg upgrade -y which updates py39-salt to 3006.1_1.
Now calling the same state with the updated salt results in tons of errors... including the one I included above, see attached log file.

Sadly I upgrade today to 3006 and it's broken on my system as well..

Code:

I tried to pip installed contextvars , but it is still not working.

Code: 
sharky@unbound ~ % pip list
Package       Version

certifi       2021.10.8
cffi          1.15.0
chardet       4.0.0
contextvars   2.4

From the contextvar readme ....


Listing as a Dependency
=======================

The good news is that the standard library always takes the
precedence over site packages, so even if a local ``contextvars``
module is installed, the one from the standard library will be used.
Therefore you can simply list "contextvars" in your
``requirements.txt`` or ``setup.py`` files.

Another option is to use `"platform specific dependencies"
<http://setuptools.readthedocs.io/en/latest/setuptools.html\
#declaring-platform-specific-dependencies>`_ setuptools feature:

.. code-block:: python

import setuptools

setuptools.setup(
name="Project",
...
install_requires=[
'contextvars;python_version<"3.7"'
]
)

1. edit /usr/local/lib/python3.9/site-packages/salt-3006.2-py3.9.egg-info/requires.txt
2. Comment out contextvars there.
3. Solved.

For me anyway. I use the package so it may be different with the port.
