[ty] Make `[abstract-method-in-final-class]` diagnostics less verbose for classes with many abstract methods by AlexWaygood · Pull Request #23379 · astral-sh/ruff

AlexWaygood · 2026-02-17T18:53:20Z

Summary

Another PR pulled out of #22898 to reduce the diff on that PR.

If an @final class has many unimplemented abstract methods, we currently emit a diagnostic with an extremely long summary message. For this snippet:

from typing import Protocol, final

class Abstract(Protocol):
    def aaaaaaaaa(self) -> int: ...
    def bbbbbbbb(self) -> int: ...
    def cccccccc(self) -> int: ...
    def dddddddddd(self) -> int: ...
    def eeeeeeee(self) -> int: ...
    def fffffff(self) -> int: ...
    def ggggggggg(self) -> int: ...
    def hhhhhhhhh(self) -> int: ...
    def iiiiiiiiii(self) -> int: ...
    def kkkkkkkkk(self) -> int: ...

@final
class StillSadlyAbstract(Abstract): ...

We currently emit this diagnostic:

Screenshot

The ecosystem report on early versions of #22898 pointed out that it's not unusual to have a class with lots of abstract methods, so the status quo here seems unreasonable. This PR limits the number of diagnostics we print to the terminal to 3 by default, unless --verbose has been specified on the command line. The new default diagnostic is:

Screenshot

And if you specify --verbose, it becomes:

Test Plan

Mdtests added.

Testing this feature necessitated adding the ability to specify verbose = true in a TOML config block in mdtests.

… for classes with many abstract methods
