should this be the target version for the whole jit directory, rather than just one file...?

| "c-analyzer/c_parser/__init__.py" = ["F401"] # Re-exports from submodules | ||

| "c-analyzer/c_parser/preprocessor/common.py" = ["F401"] # Re-exported by preprocessor/__init__.py |

Adding __all__ and listing the re-exports in __all__ would probably be a more idiomatic way of fixing these errors (but perhaps that's something for a followup PR, since there's a chance it could be controversial :-)

in a case like this where there's only one error, I'd usually lean towards using a noqa comment in the code rather than per-file-ignores. But, again, perhaps that's best done as a followup..

Keeping those linters busy man 😉 |

Is it needed to repeat it? It's already in the parent (project) configuration, no?

The parent config doesn't define a select, so defaults to ["E4", "E7", "E9", "F"].
We don't want to run the whole F category, or those other ones, so this select overwrites that one.
(There is an extend-select that is in addition to select, but we do want a smaller set here.)

Oh sorry, I mixed Lib/.ruff.toml and .ruff.toml. You're right.

GH-152916 is a backport of this pull request to the 3.15 branch. |
Follow on from #151440 and #151442.
Also add Ruff F401 to help avoid this in the future, and exclude any files with false positives (rather than adding
noqacomments).
