New lint `clippy::join_absolute_paths` #11453

xFrednet · 2023-09-02T21:43:08Z

Hey @ofeeg, this PR is a copy of all the changes you did in 47171d3 from PR #11208. I wasn't sure how to fix the git history. Hope you're okay with me figuring this out in this separate PR

changelog: New lint [join_absolute_paths]
#11453

Closes: #10655

r? @Centri3 Since you also gave feedback on the other PR. I hope that I copied everything correctly, but a third pair of eyes would be appreciated :D

+                diag
+                      .note("joining a path starting with separator will replace the path instead")
+                      .help("if this is unintentional, try removing the starting separator")
+                      .help("if this is intentional, try creating a new Path instead");


Suggested change

diag

.note("joining a path starting with separator will replace the path instead")

.help("if this is unintentional, try removing the starting separator")

.help("if this is intentional, try creating a new Path instead");

diag.note("joining a path starting with separator will replace the path instead")

.help("if this is unintentional, try removing the starting separator")

.help("if this is intentional, try creating a new Path instead");

Still a bit weird in terms of formatting. I also think we should also add suggestions here instead of just .help(...).

+        && let ExprKind::Lit(spanned) = &join_arg.kind

Does \\ do this on unix as well? Or is it normalized to / immediately? If it doesn't, we could say this behavior would only be present on windows to remove any potential confusion.

On unix it just accepts it as a file name

let path = Path::new("C:\\Users"); let path2 = path.join("\\Ducks"); println!("{path2:#?}"); -> "C:\\Users/\\Ducks"

This behavior actually makes sense to me. I'll add a note to the lint description. I wouldn't add it to the lint emission, as it's already quite verbose.

Can we use [has_root](https://github.com/rust-lang/rust-clippy/pull/11453#method.has_root) to check ?

@lengyijun I assume you mean Path::has_root()?

I don't think that it would be good to be platform specific here. I can imagine that several projects just run Clippy on linux without specifying --all-targets. This assumption comes from the fact that I often forget to specify that flag in the CI. There might also be users, who only run Clippy locally. However, this can lead to false positives, even if I don't believe that anybody wants to start their folder name with \\ on linux. So, I think we should keep the current behavior, but move the lint to suspicious, to have the lint warn by default and not deny. Does that sound good to everyone?

Everything looks fine to me, minus the nits. CI seems to agree too.

ofeeg · 2023-09-04T17:58:56Z

Looks like it all got figured out. Sorry for the trouble.

I've rebased and moved the lint to suspicious, the rest should be the same as before

I say as the CI fails... And everything should be fixed now
