Function run_make_support::scoped_run::test_while_readonly
source · pub fn test_while_readonly<P, F>(path: P, closure: F)
Expand description
Ensure that the path P is read-only while the test runs, and restore original permissions at the end so compiletest can clean up. This will panic on Windows if the path is a directory (as it would otherwise do nothing)
§Pitfalls
- Some CI runners are ran as root which may bypass read-only permission restrictions. Unclear exactly when such scenarios occur.
§FIXME
FIXME(Oneirical): This will no longer be required after compiletest receives the ability to manipulate read-only files. See https://github.com/rust-lang/rust/issues/126334.
