Description

Everything related to the __implements__ construct was removed. It was based on PEP245
that was proposed in 2001 and rejected in 2006. It includes everything in pylint.interfaces

Checker should only inherit BaseChecker or any of the other checker types from pylint.checkers.
Reporter should only inherit BaseReporter.

The capability from pyreverse to take it into account when generating diagrams was also removed.

For pyreverse there is some more code that can be cleaned up together with this.
I can push to this branch tomorrow evening, or if you want to merge beforehand create a follow-up PR.

There are a few more places in pyreverse that can be cleaned up now, but the important stuff is included and tests adapted, thanks for that!

From the first quick look the following things can be removed as well:

  • DiagramWriter.write_classes --> everything related to implementation links
  • printer.py: NodeType.INTERFACE and EdgeType.IMPLEMENTS, and for the concrete Printer classes the places where those are used

As said I can take a closer look tomorrow and create a follow up PR. Especially the NodeType.INTERFACE is something that as far as I know did not even work as intended, and I would have to take a closer look at it as well.

Changelog: https://pylint.pycqa.org/en/latest/whatsnew/3/3.0/index.html#summary-release-highlights

remove `__implements__`:
That attribute is apparently from a rejected PEP. They say to inherit
from BaseChecker, which we are already doing.
pylint-dev/pylint#8404

check_messages -> only_required_for_messages:
Seems straightforward instructions. I haven't actually tested it.
pylint-dev/pylint#8409

remove emptystring extension:
Looks like this has been replaced by https://pylint.readthedocs.io/en/stable/user_guide/messages/convention/use-implicit-booleaness-not-comparison-to-string.html
Which is disabled by default but we have `enable=ALL`, so I guess that means
we indeed have it enabled.

And update changelog URLs.
