Update plugin to support mypy 1.17.0

[Jazzinghen]

I have made things!

What was done

• Updated parameter passing for MyPy 1.16+ compatibility in returns/contrib/mypy/_features/kind.py
• Updated typesafety test files, mostly to match newer MyPy syntax
  • Union[A, B] → A | B
  • Tuple[A, B] → tuple[A, B]
  • Updated fully qualified type names and temporary module references
• Fixed string representation of Hypothesis test expectations for version 6.136+ strategy format changes (Cache, defer, and truncate sampled_from repr HypothesisWorks/hypothesis#4441)

Checklist

• I have double checked that there are no unrelated changes in this pull request (old patches, accidental config files, etc)
• I have created at least one test case for the changes I have made
• I have updated the documentation for the changes I have made
• I have added my changes to the CHANGELOG.md

Related issues

Closes #2148

I have not updated the readme as there is no strict reference to the supported mypy version, and it looks like the changelog contains release info, so I didn't touch that one either.

All the checks passed, even though I had to add an ignore flag in a function that was using some strange trait-based property access.

I used a solution very similar to the one used in typeddjango/django-stubs#2670 but I get the version info using importlib instead of the string in the module.

[Jazzinghen]

This is strange. I haven't seen these issues on my side. 🤔

You updated

name = "wemake-python-styleguide"
version = "1.1.0"

Let's pin it to 1.0 for now :)

[Jazzinghen]

Oh? I didn't notice. I think I might have just ran poetry update -U to get the latest version of Mypy and that updated everything in the lock file. Should I change the entry in pyproject.toml to limit the version to 1.0?

[sobolevn]

yes, please :)

[Jazzinghen]

Rebased against master and pinned version

@sobolevn @Jazzinghen are there any plans to continue work on this PR?

[sobolevn]

@svorcan-rho today mypy@1.17.0 was released :)
Any help is appreciated.

@sobolevn @Jazzinghen are there any plans to continue work on this PR?

I was waiting for approval after my last commit. Was there something missing?

[sobolevn]

the CI is still red, I would be happy to approve it after it is green :)

A lot of errors seem to be not very related to what I did, however I'll try to fix them. They're quite a lot, I hope I won't break anything.

[sobolevn]

Please, run poetry update to fix the ci :)

[Jazzinghen]

I guess this PR became more of a "Update all the tests to run with the newer Mypy" than just that small change I did, haha

[Jazzinghen]

Everything should be fixed now.

[sobolevn]

Awesome! Almost all fixed. Thank you! 👍

[Jazzinghen]

This is strange. I don't get the same error on my PC. I'll try to reproduce it, otherwise I might need some more info than what the CI pipeline is printing.

[Jazzinghen]

Oh, wait, the error is not generated by the command I was testing. I am dumb.

[Jazzinghen]

This was a pretty long debugging session, however it seems like mypy started checking for additional magic attributes. One of those, __await__, was checked in all the type aliases of KindN, even though it does not exist.
I hope this solution is the correct one, however if you have a better solution I'd like to hear about it. :D
