The kiosk touchscreen has no way to hard-refresh, and the service worker
served stale cached JS after updates. SpoolBuddy pages now unregister
any existing SW and skip registration entirely. Regular desktop/mobile
users still get the SW. Restored kiosk restart in SSH update flow since
SW is no longer an obstacle.
Check button had no visual feedback because isFetching doesn't trigger
reliably with cached data — replaced with manual loading state. Removed
kiosk restart via getty; the frontend now detects daemon re-registration
via WebSocket and calls window.location.reload(), keeping the user on
the same page and fetching all fresh data.
The SSH update set status to "complete" after the daemon had already
restarted and re-registered, overwriting the cleared state so it stuck
forever. Removed the post-restart "complete" write — daemon
re-registration is now the completion signal, clearing any update status.
The daemon's self-update mechanism (git fetch/reset on its own code) was
fragile: .git permission errors, self-modifying code mid-run, hardcoded
main branch. Bambuddy now SSHes into the SpoolBuddy Pi and drives the
update remotely — matching its own branch, with step-by-step progress
via WebSocket. After updating the daemon, the kiosk browser is also
restarted so it loads the updated frontend.
SSH key pairing is automatic: Bambuddy generates an ED25519 keypair and
returns the public key in the registration response. The daemon deploys
it to authorized_keys on first connect — no manual setup needed.
Changes:
- New: backend/app/services/spoolbuddy_ssh.py
- Rewritten: trigger_daemon_update endpoint (SSH instead of pending_command)
- New: GET /spoolbuddy/ssh/public-key endpoint
- Auto SSH key deployment via registration response + daemon
- Removed: daemon _perform_update() and cmd=="update" handler
- Install script: bash shell, sudoers for daemon + kiosk restart, .ssh/ setup
- Dockerfile: added openssh-client
- Frontend: SSH key display, force update button
- Fixed: update check compares APP_VERSION, not GitHub releases
- Fixed: kiosk browser restart after update
