Describe your change:

% ruff rule RUF012

mutable-class-default (RUF012)

Derived from the Ruff-specific rules linter.

What it does

Checks for mutable default values in class attributes.

Why is this bad?

Mutable default values share state across all instances of the class,
while not being obvious. This can lead to bugs when the attributes are
changed in one instance, as those changes will unexpectedly affect all
other instances.

When mutable value are intended, they should be annotated with
typing.ClassVar.

Examples

classA:
mutable_default: list[int] = []

Use instead:

fromtypingimportClassVarclassA:
mutable_default: ClassVar[list[int]] = []

% ruff rule RUF012

mutable-class-default (RUF012)

Derived from the Ruff-specific rules linter.

What it does

Checks for mutable default values in class attributes.

Why is this bad?

Mutable default values share state across all instances of the class,
while not being obvious. This can lead to bugs when the attributes are
changed in one instance, as those changes will unexpectedly affect all
other instances.

When mutable value are intended, they should be annotated with
typing.ClassVar.

Examples

classA:
mutable_default: list[int] = []

Use instead:

fromtypingimportClassVarclassA:
mutable_default: ClassVar[list[int]] = []

I think we should wait. We've received a few issues with the latest changes to this rule.

All new PRs are failing. Should we ignore RUF012 in pyproject.tml?
