temporary home

Error message

temporary home

What it means

Test setup assertion in `audit_retirement_validates_tree_and_removes_only_verified_source`: `tempfile::tempdir()` must yield a scratch home directory for constructing an `AstridHome`. The `expect("temporary home")` fires when the OS cannot create the temporary directory (permissions or path issues), so the retirement test cannot run.

Solutions

1. Free space / fix permissions on the temp filesystem used by the test runner.
2. Set `TMPDIR` to a writable location before running the tests.
3. If sandbox rules block tempfile, allow writes to the system temp dir in the sandbox config.
4. Retry the test once if the failure was transient (e.g. concurrent cleanup).

Example fix

// before
let directory = tempfile::tempdir().expect("temporary home");
// after
let directory = tempfile::tempdir()
    .unwrap_or_else(|e| panic!("tempdir creation failed (check TMPDIR/permissions): {e}"));

// Rust (test/CI): verify temp dir writability before running
let probe = std::env::temp_dir().join(".write_probe");
std::fs::write(&probe, b"x").expect("TMPDIR not writable");
let _ = std::fs::remove_file(&probe);

// Rust: report environment context on tempdir failure
let directory = tempfile::tempdir()
    .unwrap_or_else(|e| panic!("tempdir failed (TMPDIR={:?}): {e}", std::env::var("TMPDIR").ok()));

When it happens

Trigger: Calling `tempfile::tempdir()` when creating a directory under `$TMPDIR` fails — read-only /tmp, full filesystem, restricted permissions, or TMPDIR pointing at a non-writable path.

Common situations: CI runners with read-only or quota-exhausted temp dirs, sandboxed test environments blocking tmp creation, or a bad `TMPDIR` env var in the developer's shell.
