| // This invalidates the build if any untracked files change. That's sufficient for the case | |
| // where we transition from dirty to clean. | |
| // | |
| // There's an edge-case here where the repository could be newly dirty, but we can't know | |
| // because our build hasn't been invalidated, since the untracked files weren't untracked last | |
| // time we ran. That will cause us to incorrectly report ourselves as clean. | |

| // However, in practice that shouldn't be much of an issue: If no other dependency of this | |
| // top-level crate has changed (which would've triggered our rebuild), then the resulting binary | |
| // must be equivalent to a clean build anyways. Therefore, persistent caching using the HEAD | |
