Note that unfortunately the warning still points to file of dependencies, which is wrong 😞 |

Seems reasonable to me!
@ehuss mind also taking a look though? You're more in the thick-of-things with cargo fix than I am.

Could the test mostly just assert that nothing is fixed, which means that this wouldn't break when rust-lang/rust is updated?

Sure! Updated. Thank for the review 😆

Thanks! Looks good. I have two minor concerns, but I don't think they are too important:

Fix fix::fix_in_dependency to not rely on rustc This changes the `fix::fix_in_dependency` test so that it does not rely on the behavior of rustc. This test is checking the behavior when rustc includes a suggestion diagnostic that modifies a file in CARGO_HOME from a dependency. rustc should not be emitting suggestions that point outside of the current crate, but there are some known bugs where it does this. #9938 added a workaround for this to avoid writing to CARGO_HOME. However, the current test was relying on one of those bugs in rustc to exhibit its behavior. rust-lang/rust#119204 is fixing that particular behavior. Instead of relying on issues in rustc, this PR changes the test so that the test creates a fake `rustc` executable that will emit a hard-coded JSON message that tells `cargo fix` to modify a file in CARGO_HOME. This should be stable as it is no longer relying on rustc. Testing or validating this change is a little tricky. You have to essentially comment out [these three lines](https://github.com/rust-lang/cargo/blob/4f70d1781a2b2d3611087e1ee6e8096903c9b73a/src/cargo/ops/fix.rs#L654-L656) from the original #9938 change, and verify that the test fails (it says "Fixed" in the output). With those three lines in place, it should pass.
