Uff, reverting this broke lintcheck again :(
Maybe we have to keep workspace.exclude = target/lintcheck/crates ?

camsteffen · 2021-02-28T02:12:55Z

Hmm how can that be?

matthiaskrgr · 2021-02-28T10:06:48Z

I'm not really sure yet.
It seems to work fine on the master branch.
On my WIP branch I did a rebase and now I get panics inside clippy_dev::clippy_project_root()
But if I revert the rebase, everything seems to work fine 🤔

I've fixed the issue by redoing one of my commits but I still have no idea what caused this 🤷 😄

flip1995 · 2021-03-02T09:56:10Z

With this change, the dogfood test doesn't actually run. 🤔

flip1995 · 2021-03-02T11:00:55Z

I found the reason. If something is a (path) dep and not a workspace member, cargo will run rustc on that (path) dep instead of the RUSTC_WORKSPACE_WRAPPER. This can be seen in this verbose output:

@ehuss Is this intended behavior?

If this is intended, I guess this part of Clippy is really useless:

rust-clippy/src/driver.rs

Lines 294 to 306 in 3cd6ca0

    
           // We enable Clippy if one of the following conditions is met 
        
           // - IF Clippy is run on its test suite OR 
        
           // - IF Clippy is run on the main crate, not on deps (`!cap_lints_allow`) THEN 
        
           //    - IF `--no-deps` is not set (`!no_deps`) OR 
        
           //    - IF `--no-deps` is set and Clippy is run on the specified primary package 
        
           let clippy_tests_set = env::var("__CLIPPY_INTERNAL_TESTS").map_or(false, |val| val == "true"); 
        
           let cap_lints_allow = arg_value(&orig_args, "--cap-lints", |val| val == "allow").is_some(); 
        
           let in_primary_package = env::var("CARGO_PRIMARY_PACKAGE").is_ok(); 
        
           let clippy_enabled = clippy_tests_set || (!cap_lints_allow && (!no_deps || in_primary_package)); 
        
           if clippy_enabled { 
        
               args.extend(clippy_args); 
        
           }

Where are you seeing the dogfood test not run?

flip1995 · 2021-03-02T16:53:03Z

If I run cargo clippy inside clippy_lints on the current master branch, I get multiple lint warnings. But dogfood succeeds. So I guess it doesn't really run.

ehuss · 2021-03-02T17:06:18Z

@ehuss Is this intended behavior?

Yes. There is a subtle distinction that path dependencies in a [workspace] are members of the workspace, but without [workspace] they are not.

camsteffen · 2021-03-02T17:09:14Z

Ugh. I thought I had it working...

flip1995 · 2021-03-02T17:57:19Z

I have a fix, but after fixing 5 or 6 errors in Clippy, now the lintcheck tool triggers 30 Clippy lints (cough @matthiaskrgr cough). 😄

I will fix them and open a PR tomorrow.

camsteffen · 2021-03-02T18:10:19Z

Ok cool. It seems like the dogfood "subprojects" test can become "test all the things"?

matthiaskrgr · 2021-03-02T19:09:06Z

, now the lintcheck tool triggers 30 Clippy lints

oh no.. I'll have a look 😅

flip1995 · 2021-03-02T19:37:01Z

Yep, that's exactly my fix.

Dogfood and CI fixes The CI fix is practically #6829 rebased and squashed into one commit Dogfood fix is a follow up of #6802 r? `@matthiaskrgr` for lintcheck changes (best reviewed with whitespace changes hidden) changelog: none
