From c3c031e4e4456c18b5dce889e45c2b3ce7305ca9 Mon Sep 17 00:00:00 2001 From: spencrmartin Date: Fri, 14 Nov 2025 11:19:36 -0500 Subject: [PATCH] fix: prevent duplicate message rendering in collaborative sessions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ๐Ÿ”ง MESSAGE DEDUPLICATION: Eliminate double rendering when second user sends messages ## Root Cause Analysis: Messages from other users were being processed by multiple event handlers: 1. Regular 'message' event handler 2. Goose message detection (heuristic) 3. Session message handler This caused the same message to appear multiple times in the chat. ## Solution Implementation: ### Enhanced Message Classification: โœ… Added message type flags (isGooseMessage, isSessionMessage) โœ… Use else-if chain to ensure only one handler processes each message โœ… Prevent multiple event emissions for the same message ### Smart Event Routing: โœ… Regular messages: Only emit 'message' if not Goose/session message โœ… Goose messages: Emit 'gooseMessage' + special 'gooseSessionSync' for collaboration โœ… Session messages: Emit 'sessionMessage' for legacy session handling โœ… Structured logging to track which handler processes each message ### Enhanced Matrix Context: โœ… Updated onMessage to support both default and named event listeners โœ… Overloaded function signature for backward compatibility โœ… Support for 'gooseSessionSync' event in useSessionSharing ### Session Sharing Integration: โœ… Added listener for 'gooseSessionSync' events โœ… Proper cleanup for all event listeners โœ… Maintains existing functionality while preventing duplicates ## Technical Flow: 1. Message received โ†’ Classify as regular/Goose/session 2. Emit appropriate event(s) โ†’ Only one primary handler per message 3. UI renders once โ†’ No duplicate message components 4. Collaboration sync โ†’ Works via dedicated 'gooseSessionSync' event ## Benefits: ๐ŸŽฏ **No More Duplicates**: Each message renders exactly once ๐Ÿ”„ **Preserved Functionality**: All existing features still work ๐Ÿฆ† **Goose Communication**: Still detects and handles Goose messages ๐Ÿ“ **Session Sync**: Collaborative sessions work without duplicates ๐Ÿงน **Clean Logging**: Clear indication of message processing path Now when a second user sends a message in a collaborative session, it will appear exactly once with the correct sender avatar! ๐Ÿฆ†โœจ --- ui/desktop/src/contexts/MatrixContext.tsx | 17 +++++++-- ui/desktop/src/hooks/useSessionSharing.ts | 2 + ui/desktop/src/services/MatrixService.ts | 45 ++++++++++++++++------- 3 files changed, 46 insertions(+), 18 deletions(-) diff --git a/ui/desktop/src/contexts/MatrixContext.tsx b/ui/desktop/src/contexts/MatrixContext.tsx index 69da76e721..fc27d21602 100644 --- a/ui/desktop/src/contexts/MatrixContext.tsx +++ b/ui/desktop/src/contexts/MatrixContext.tsx @@ -38,7 +38,7 @@ interface MatrixContextType { getOrCreateDirectMessageRoom: (userId: string) => Promise; // Events - onMessage: (callback: (data: any) => void) => () => void; + onMessage: ((callback: (data: any) => void) => () => void) & ((eventName: string, callback: (data: any) => void) => () => void); onAIMessage: (callback: (message: GooseAIMessage) => void) => () => void; onGooseMessage: (callback: (message: GooseChatMessage) => void) => () => void; onSessionMessage: (callback: (data: any) => void) => () => void; @@ -191,9 +191,18 @@ export const MatrixProvider: React.FC = ({ children, matrix await matrixService.setDisplayName(displayName); }; - const onMessage = (callback: (data: any) => void) => { - matrixService.on('message', callback); - return () => matrixService.off('message', callback); + const onMessage = (eventNameOrCallback: string | ((data: any) => void), callback?: (data: any) => void) => { + if (typeof eventNameOrCallback === 'string' && callback) { + // Support for specific event names like 'gooseSessionSync' + matrixService.on(eventNameOrCallback, callback); + return () => matrixService.off(eventNameOrCallback, callback); + } else if (typeof eventNameOrCallback === 'function') { + // Default behavior for 'message' event + matrixService.on('message', eventNameOrCallback); + return () => matrixService.off('message', eventNameOrCallback); + } else { + throw new Error('Invalid arguments for onMessage'); + } }; const onAIMessage = (callback: (message: GooseAIMessage) => void) => { diff --git a/ui/desktop/src/hooks/useSessionSharing.ts b/ui/desktop/src/hooks/useSessionSharing.ts index a50d79e1f9..4eb7c255e1 100644 --- a/ui/desktop/src/hooks/useSessionSharing.ts +++ b/ui/desktop/src/hooks/useSessionSharing.ts @@ -208,10 +208,12 @@ export const useSessionSharing = ({ const sessionCleanup = onSessionMessage(handleSessionMessage); const messageCleanup = onMessage(handleRegularMessage); + const gooseSessionCleanup = onMessage('gooseSessionSync', handleRegularMessage); return () => { sessionCleanup(); messageCleanup(); + gooseSessionCleanup(); }; }, [isConnected, sessionId, state.roomId, currentUser?.userId, onSessionMessage, onMessage, onMessageSync, onParticipantJoin]); diff --git a/ui/desktop/src/services/MatrixService.ts b/ui/desktop/src/services/MatrixService.ts index 8f67942ef3..79b3edda91 100644 --- a/ui/desktop/src/services/MatrixService.ts +++ b/ui/desktop/src/services/MatrixService.ts @@ -495,8 +495,12 @@ export class MatrixService extends EventEmitter { senderInfo, }; + let isGooseMessage = false; + let isSessionMessage = false; + // Check if this is a structured Goose message (new format) if (content['goose.message.type']) { + isGooseMessage = true; const gooseChatMessage: GooseChatMessage = { type: content['goose.message.type'] as any, messageId: content['goose.message.id'] || this.generateMessageId(), @@ -517,14 +521,13 @@ export class MatrixService extends EventEmitter { }, }; - console.log('๐Ÿฆ† Received Goose message:', gooseChatMessage.type, 'from:', sender, isFromSelf ?
