- Fix ReactionGroup.count: i64 -> i32 and users: Vec<Uuid> -> Vec<String>
to match frontend ReactionItem (count: number, users: string[]).
Mismatched types caused the WS reaction update to silently fail.
Also update ReactionItem in api/ws_types.rs to match.
- Add activeRoomIdRef guard in onRoomReactionUpdated to prevent stale
room state from processing outdated events after room switch.
- Switch from prev.map() to targeted findIndex+spread in onRoomReactionUpdated
to avoid unnecessary array recreation.
Backend:
- Add reaction_batch handler: GET /api/rooms/{room_id}/messages/reactions/batch?message_ids=...
- Register route in libs/api/room/mod.rs
- Backend already had message_reactions_batch service method, just needed HTTP exposure
Frontend:
- Add ReactionListData import to room-context.tsx
- Fix thisLoadReactions client type (was using broken NonNullable<ReturnType<>>)
- Remove unused oldRoomId variable
- Delete unused useRoomWs.ts hook (RoomWsClient has no on/off methods)
- Remove unused EmojiPicker function and old manual overlay picker from RoomMessageBubble
- Remove unused savedToken variable in room-ws-client
- reaction.rs: query before insert to detect new vs duplicate reactions,
only publish Redis event when a reaction was actually added
- room.rs: delete Redis seq key on room deletion to prevent seq
collision on re-creation
- message.rs: use Redis-atomic next_room_message_seq_internal for
concurrent safety; look up sender display name once for both
mention notifications and response body; add warn log when
should_ai_respond fails instead of silent unwrap_or(false)
- ws_universal.rs: re-check room access permission when re-subscribing
dead streams after error to prevent revoked permissions being bypassed
- RoomChatPanel.tsx: truncate reply preview content to 80 chars
- RoomMessageList.tsx: remove redundant inline style on message row div
- Add `check_room_access` before `manager.subscribe()` in ws_universal
to prevent unauthorized room subscription (security fix)
- Fix busy-wait in `poll_push_streams`: sleep 50ms when streams are
empty, yield only when there are active streams
- Re-subscribe dead rooms after stream errors so events are not
permanently lost until manual reconnect
- Fix streaming message placeholder using fake content as room_id:
use chunk.room_id from backend instead
- Show toast error on history load failures instead of silent fallback
Backend:
- Atomic seq assignment via Redis Lua script: INCR + GET run atomically
inside a Lua script, preventing duplicate seqs under concurrent requests.
DB reconciliation only triggers on cross-server handoff (rare path).
- Broadcast channel capacity: 10,000 → 100,000 to prevent message drops
under high-throughput rooms.
Frontend:
- Optimistic sendMessage: adds message to UI immediately (marked
isOptimistic=true) so user sees it instantly. Replaces with
server-confirmed message on success, marks as isOptimisticError on
failure. Fire-and-forget to IndexedDB for persistence.
- Seq-based dedup in onRoomMessage: replaces optimistic message by
matching seq, preventing duplicates when WS arrives before REST confirm.
- Reconnect jitter: replaced deterministic backoff with full jitter
(random within backoff window), preventing thundering herd on server
restart.
- Visual WS status dot in room header: green=connected, amber
(pulsing)=connecting, red=error/disconnected.
- isPending check extended to cover both old 'temp-' prefix and new
isOptimistic flag, showing 'Sending...' / 'Failed' badges.
validate_origin() only allowed localhost origins by default, causing
production WebSocket connections to be rejected. Now it reads
APP_DOMAIN_URL and APP_STATIC_DOMAIN from env and automatically
adds their http/https/ws/wss variants to the allowed origins list.
Also add APP_DOMAIN_URL to the production configmap.
