Error message

redirect fixture

What it means

The message "redirect fixture" is the expect() on std::os::unix::fs::symlink(&outside, principal_home.audit_dir().join("redirect")) at audit_retirement_tests.rs:35-36. This plants a symlink named 'redirect' inside the principal's audit directory pointing outside the tree — the exact pattern retire_legacy_audit_dir must reject. The expect panics if symlink creation fails; the function is unix-only (the test is cfg(unix)) and fails on filesystems or platforms that disallow symlinks, or if audit_dir does not exist.

Solutions

1. Confirm principal_home.ensure() ran and created audit_dir before line 35.
2. Check no prior run left a 'redirect' entry in the audit dir; tempdirs should be unique, so prefer fixing a shared-path bug over deleting manually.
3. Run on a native unix filesystem with symlink support (ext4/apfs); avoid network mounts for cargo test target dirs.
4. Since retire_legacy_audit_dir must reject this symlink, keep the fixture; only change creation mechanics, not the semantics.

Example fix

// before
std::os::unix::fs::symlink(&outside, principal_home.audit_dir().join("redirect"))
    .expect("redirect fixture");
// after
let link = principal_home.audit_dir().join("redirect");
std::os::unix::fs::symlink(&outside, &link)
    .unwrap_or_else(|e| panic!("redirect fixture: symlink {} -> {}: {e}", link.display(), outside.display()));

let link = principal_home.audit_dir().join("redirect");
if link.symlink_metadata().is_ok() {
    panic!("redirect fixture: {} already exists", link.display());
}
if !principal_home.audit_dir().is_dir() {
    panic!("redirect fixture: audit dir missing");
}

fn symlinks_supported(dir: &std::path::Path) -> bool {
    let probe = dir.join(".symlink-probe");
    match std::os::unix::fs::symlink("target", &probe) {
        Ok(_) => { std::fs::remove_file(&probe).ok(); true }
        Err(_) => false,
    }
}

std::os::unix::fs::symlink(&outside, &link)
    .unwrap_or_else(|e| panic!("redirect fixture: {} -> {}: {e}", link.display(), outside.display()));

When it happens

Trigger: symlink() returns Err: audit_dir was never created by ensure(), a file/symlink named 'redirect' already exists (AlreadyExists), the filesystem is Windows/NTFS or a mount with symlinks disabled (EPERM), or permissions block inode creation in audit_dir.

Common situations: Running the unix-gated test on filesystems without symlink support (FAT/exFAT mounts, some Windows Developer-mode setups if cfg(unix) were removed); running tests as a user without symlink privileges; ensure() regressions leaving audit_dir absent.
