- RoomMessageSearch.tsx: add explicit generic type for resp.data
- RoomPinPanel.tsx: make sender_id optional (string | null)
- message-list.tsx: remove unused index variable in map
- repository-context.tsx: use correct RepoInfo field names
- use-audio-recording.ts: use audioStream state instead of undefined var
- universal-ws.ts: rename unused id to _id
- SSH rate limiter: wire SshRateLimiter into SSHServer with IP-based
rate limiting on new_client connections
- Room startup: cap initial room load at 1000 via limit() to prevent
resource exhaustion on large instances
- WS token exposure: only include token in URL for cross-origin
connections; same-origin web clients authenticate via secure cookies
- CSRF: confirmed SameSite::Lax + Secure + HttpOnly are all set
(session config defaults)
Clear wsToken on auth-related close codes (3000-4999), connection
timeout, and after 3 consecutive reconnect failures so the next connect
attempt fetches a fresh token. Add onRoomAiUpdated and onRepoChanged
callbacks that re-fetch AI configs and repo list when pushed via WS.
Fix AI member list to never display raw UUID.
Add 'repo' to MentionType across all editor types, include repos in the
@ trigger pool, add repo badge (green chip), Repos section in the
mention dropdown, and MentionBadge styles. Wire projectRepos from
room context into IMEditor mentionItems.
- TypingUsers state split by sender_type: AI vs human typing
- AI typing shows "{Name} is thinking..." with accent color
- Human typing shows "{Name} is typing..." with muted style
- AI typing relies on backend 60s TTL stop (no client-side 4s fallback)
- Add Page Visibility API to reconnect WS on tab become visible
- Add debug logs for typing flow tracing
- Pass sender_type through WS room.typing event routing
- MessageInput: ignore empty text in handleEditorUpdate to avoid
TipTap's onUpdate("") on init clearing the typing state
- DiscordChatPanel: show typing indicator when other users are typing
- room-context: wire onTypingStart/Stop into ws callbacks
- Remove duplicate smooth scroll effect from DiscordChatPanel; handle
all scroll logic in MessageList instead
- MessageList: track isInitialLoadRef to instant-jump to bottom on
first load (no animation), and only auto-scroll for new messages
when user is already near the bottom
- sender.ts: getSenderDisplayName rejects UUID values and falls back
to 'AI' for AI messages; getSenderModelId uses display_name
- Rewrite DiscordChannelSidebar with @dnd-kit drag-and-drop:
rooms are sortable within categories; dragging onto a different
category header assigns the room to that category
- Add inline 'Add Category' button: Enter/Esc to confirm/cancel
- Wire category create/move handlers in room.tsx via RoomContext
- Fix onAiStreamChunk to accumulate content properly and avoid
redundant re-renders during AI streaming (dedup guard)
- No backend changes needed: category CRUD and room category update
endpoints were already wired
- Refactor room-context.tsx with improved WebSocket state management
- Enhance room-ws-client.ts with reconnect logic and message handling
- Update Discord layout components with message editor improvements
- Add WebSocket universal endpoint support in ws_universal.rs
Frontend:
- Add Discord-style 3-column layout (server icons / channel sidebar / chat)
- AI Studio design system: new CSS token palette (--room-* vars)
- Replace all hardcoded Discord colors with CSS variable tokens
- Add RoomSettingsPanel (name, visibility, AI model management)
- Settings + Member list panels mutually exclusive (don't overlap)
- AI models shown at top of member list with green accent
- Fix TS errors: TipTap SuggestionOptions, unused imports, StarterKit options
- Remove MentionInput, MentionPopover, old room components (废弃代码清理)
Backend:
- RoomAiResponse returns model_name from agents.model JOIN
- room_ai_list and room_ai_upsert fetch model name for each config
- AiConfigData ws-protocol interface updated with model_name
Note: RoomSettingsPanel UI still uses shadcn defaults (未完全迁移到AI Studio)
Replace module-level refs and circular dependencies with a centralized
mention state hook (useMentionState) and shared types (mention-types).
- Introduce mention-types.ts for shared types (avoid circular deps)
- Introduce mention-state.ts with useMentionState hook (replace global refs)
- Rewrite MentionInput as contenteditable with AST-based mention rendering
- Rewrite MentionPopover to use props-only communication (no module refs)
- Fix MessageMentions import cycle (mention-types instead of MentionPopover)
- Wire ChatInputArea to useMentionState with proper cursor handling
Problem: showMentionPopover state is stale when handleKeyDown fires
immediately after handleChange (both in same event loop), causing Enter
to be silently swallowed.
Solution:
- Read textarea.value directly in handleKeyDown to detect @ mentions
- Module-level refs (mentionSelectedIdxRef, mentionVisibleRef) share
selection state between MentionPopover and ChatInputArea
- handleMentionSelect reads DOM instead of relying on props state
Backend:
- Add MENTION_TAG_RE matching new `<mention type="..." id="...">label</mention>` format
- Extend extract_mentions() and resolve_mentions() to parse new format (legacy backward-compatible)
Frontend:
- New src/lib/mention-ast.ts: AST types (TextNode, MentionNode, AiActionNode),
parse() and serialize() functions for AST↔HTML conversion
- MentionPopover: load @repository: from project repos, @ai: from room_ai configs
(not room members); output new HTML format with ID instead of label
- MessageMentions: use AST parse() for rendering (falls back to legacy parser)
- ChatInputArea: insertMention now produces `<mention type="user" id="...">label</mention>`
- RoomParticipantsPanel: onMention passes member UUID to insertMention
- RoomContext: add projectRepos and roomAiConfigs for mention data sources
Root cause: publish_reaction_event sends a RoomMessageEvent (not
reaction_added) with reactions field set. The onRoomMessage handler
previously returned prev immediately when a duplicate ID was found,
skipping the reaction update entirely.
Fix:
- Add reactions field to RoomMessagePayload so TypeScript knows it's there
- When a duplicate message ID is found AND payload carries reactions,
update the existing message's reactions field instead of ignoring
- ReactionItem and ReactionGroup have identical shapes, so assignment works
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
On auto-reconnect (scheduleReconnect), attempt connection with the stored
wsToken first. If the WS closes immediately (server rejected the token),
fall back to fetching a fresh token and retrying. Only requests a new
token when the existing one fails or when connect() is called manually
with forceNewToken=true.
- Remove clearRoomMessages on room switch: IDB cache now persists across
visits, enabling instant re-entry without API round-trip
- Increase initial API limit from 50 → 200: more messages cached upfront
- Add loadOlderMessagesFromIdb: uses 'by_room_seq' compound index to
serve scroll-back history from IDB without API call
- loadMore now tries IDB first before falling back to API
- sendMessage: guard with sendingRef to prevent concurrent in-flight
sends (was missing — rapid clicks could create duplicate messages)
- resubscribeAll: log at warn level instead of silently swallowing,
so operators can observe auth expiry or persistent failure patterns
- RoomMessageBubble: apply opacity-60 when isPending or isFailed,
and hide action toolbar for pending messages (can't react/act on
unconfirmed messages)
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.
