This version is already two releases out of support, but is "only" 7
years old so is probably still being used in the real world. Document
this version along with some other testing dependencies. Remove code
support for earlier versions. Disable ruff checks that need a newer
version.
Mostly, this means two blank lines between classes and functions and one
line between methods. Since these checks are currently in preview, they
are done in a separate ruff invocation to avoid turning ALL the preview
checks on at the same time.
- Checks for missing explicit `return` statements at the end of functions
that can return non-`None` values.
- Checks for classes that inherit from `object`.
- Checks for useless expressions.
- Within an `except*` clause, raise exceptions with `raise ... from err`
or `raise ... from None` to distinguish them from errors in exception
handling
- Checks for variable assignments that immediately precede a `return` of the
assigned variable.
- Checks for `else` statements with a `return` statement in the preceding
`if` block.
- Checks for unnecessary parentheses on raised exceptions.
Closes: #21258
This makes it easier for users to run it with the correct options
locally. Also, update the ruff, pytype and cmakelint versions to the
latest current ones.
Closes#17343
