Two dashboard-accuracy improvements for issue #3. Disconnect debounce (5s): - Brief transient flaps (Engine.IO ping miss, eviction-then-reconnect, Wi-Fi blip) no longer immediately flip the device to offline in the dashboard. Disconnect handler now defers the offline transition; register handlers cancel the pending timer if reconnect lands in window. - Existing stale-disconnect guard kept as fast-path for the eviction case (no timer scheduled at all when the active heartbeat conn is already a different socket). - Re-check at timer fire compares socketIds: aborts only if a GENUINELY DIFFERENT socket reclaimed the device. Just the closing socket's own (not-yet-cleaned-up) entry is treated as stale and proceeds with offline transition. - Server-restart mid-grace is handled by the heartbeat checker safety net (existing component): any 'online' row with last_heartbeat older than heartbeatTimeout gets marked offline on next sweep. Truthful single-device command feedback: - dashboard:device-command handler now checks deviceNs.adapter.rooms for an active socket before emitting (matches the group-command route's pattern). - If room is empty, falls through to commandQueue.queueCommand (lazy require - if commit C is reverted, MODULE_NOT_FOUND is cached and every subsequent call gets consistent queued=false behavior). - Returns three-state ack to caller: { delivered, queued, reason }. - Server log line was misleading - now logs 'Command delivered to device X' vs 'Command for offline device X (queued=true/false)'. Frontend: - sendCommand() takes optional callback. Without one, fires-and-forgets (no behavior change for non-wired callers). With one, uses Socket.IO .timeout(5000).emit so the callback always fires (ack or no_ack). - Six device-detail command buttons wired to three-state toasts: reboot, shutdown, screen_off, screen_on, launch, update. - delivered: green/success toast (existing localized message) - queued: amber/warning toast (new generic message) - no_ack: red/error toast - fallback: red/error toast - Two callers intentionally left fire-and-forget: - window._sendCmd (generic remote-overlay keypress/touch helper) - enable_system_capture (has its own visual state machine; out of scope for this commit) Three new i18n keys (en.js only; other locales follow later): - device.toast.command_queued - device.toast.command_undeliverable - device.toast.command_no_ack Refs #3 Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |
