Summary

  • write auth-profile temp files with owner-only permissions on Unix so auth-profiles.json is published as 0600 after atomic replacement
  • clear both positive and negative current-user caches during clear_session so same-token re-login cannot reuse stale session state
  • add regression coverage for the file mode and cache reset behavior

Fixes #5724.
Fixes #5758.

Tests

  • cargo fmt --all -- --check
  • git diff --check
  • CARGO_INCREMENTAL=0 cargo test -p openhuman --lib clearing_current_user_caches_drops_positive_and_negative_entries
  • CARGO_INCREMENTAL=0 cargo test -p openhuman --lib auth_profile_store_is_owner_only_after_create_and_update
  • CARGO_INCREMENTAL=0 cargo clippy -p openhuman -- -D warnings

Summary by CodeRabbit

  • Bug Fixes

    • Signing out now immediately clears cached user information and recorded lookup failures, preventing stale account state from appearing.
    • Authentication profile files on Unix systems are now restricted to the account owner, improving credential protection during creation and updates.
  • Tests

    • Added coverage to verify cache clearing removes both successful and failed lookup records.
    • Added checks confirming secure permissions for newly created and updated authentication profiles.

Review Change Stack

📝 Walkthrough

Walkthrough

The change adds a public reset for current-user caches, calls it during logout, and hardens Unix auth profile persistence by creating temporary files with mode 0600. Tests cover cache invalidation and permissions after initial and replacement writes.

Changes

Session and credential security

Layer / File(s) Summary
Current-user cache reset and logout integration
src/openhuman/desktop/app_state/ops.rs, src/openhuman/security/credentials/ops.rs, src/openhuman/desktop/app_state/ops_tests.rs
clear_current_user_caches clears positive and failure caches. clear_session calls it after removing the session profile. Tests verify both entries are removed.
Auth profile file permissions
src/openhuman/security/credentials/profiles.rs, src/openhuman/security/credentials/profiles_tests.rs
Unix temporary auth profile files are created with mode 0600. The test verifies this mode after creation and replacement. Non-Unix writing retains the existing behavior.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟠 High · up to 092cd

This PR hardens auth-profile file permissions and logout cache invalidation, but it is not merge-ready while the current implementation can fail to compile on Windows and can leave stale session state when profile removal encounters an error.

A rabbit clears the cached trail

And locks the token-file rail
Fresh writes hide from prying sight
Old logout ghosts depart at night
The burrow rests, secure and bright

Explanation

The changes satisfy both linked issues. Auth-profile temporary files use Unix mode 0600 and tests cover initial creation and replacement. clear_session clears both positive and negative current-user caches, with regression coverage.

P1 Badge Keep lock-writing imports available on Windows

On non-Unix builds these imports disappear, but this module still uses bare OpenOptions in acquire_lock() and relies on the Write trait for the writeln!(file, ...) call that records the lock owner. That means the shipped Windows desktop target fails to compile even though only the temp-profile writer needed Unix-specific permissions; keep the shared lock-file imports unconditional or use fully qualified names inside the Unix-only helper.

🔒 Security & Privacy | 🟠 Major | ⚡ Quick win

Clear current-user caches even when profile removal fails.

The ? at Line 813 returns before Line 814 on lock or filesystem errors. clear_session has already set the signed-out scheduler state at Line 808, so this path can leave stale positive or negative current-user entries in the process. Clear the caches before propagating the removal error.

Proposed fix
-let removed = auth
-    .remove_profile(APP_SESSION_PROVIDER, DEFAULT_AUTH_PROFILE_NAME)
-    .map_err(|e| e.to_string())?;

🎯 Functional Correctness | 🔴 Critical | ⚡ Quick win

Keep OpenOptions available on all targets.

The cross-platform lock path calls OpenOptions::new() at Line 1238. Gating the std::fs::OpenOptions import with #[cfg(unix)] makes the Windows build fail with an unresolved type. Keep this import unconditional and gate only Unix-specific extensions.

Proposed import fix
-use std::fs;
-#[cfg(unix)]
-use std::fs::OpenOptions;
+use std::fs::{self, OpenOptions};
