Fix #1449
After #1391 introduced proactive token refresh at half the token lifetime, users on rotating-refresh-token IdPs (reported with Authentikk #1175 and #1449 for context.) get bounced through the full OIDC re-login flow during active sessions, losing unsaved work.
TokenService::checkLoginToken()runs on every request (wired inApplication::boot). Once the token passes half-life, every request, including parallel background polls (notifications, user_status heartbeat), attempts a refresh. With refresh-token rotation, two concurrent requests race: the winner refreshes and the IdP rotates/invalidates the old refresh token; the loser then presents that already-rotated token, which the IdP rejects (or treats as token-reuse and revokes the whole family).The token can no longer be refreshed, so
reauthenticate()issues a hard redirect.The per-session lock added in #1391 didn't prevent this: its double-check read
$this->session(a per-request in-memory snapshot), which is stale on non-locking session backends (Redis/memcached), exactly the setups where parallel requests aren't serialized.🤖 AI (if applicable)
