 # GoChat Multi-Container Deployment - Change Log
 
+## 2026-01-26
+
+### Session: Fixed Messages Not Displaying Bug
+
+**Bug Fix: Messages Not Displaying After Send**
+- Fixed critical bug where sent messages were not appearing in chat window in real-time
+- Root cause: WebSocket port mismatch between frontend and Docker configuration
+
+**Root Cause Analysis:**
+1. Frontend hardcodes WebSocket URL as `ws://127.0.0.1:7000/ws`
+2. `.env` file had `WS_PORT=17000`, mapping container port 7000 to host port 17000
+3. Frontend could not connect to WebSocket, so real-time message delivery failed
+4. Messages were saved to database successfully, but not pushed via WebSocket
+
+**Fixes Applied:**
+
+**.env**
+- Changed `WS_PORT=17000` to `WS_PORT=7000` to match frontend expectation
+
+**api/rpc/rpc.go** (Additional improvement)
+- Added proper error handling for all RPC client functions
+- Now returns `FailReplyCode` when RPC calls fail instead of silently succeeding
+- Affected functions: `Login`, `Register`, `GetUserNameByUserId`, `CheckAuth`, `Logout`, `Push`, `PushRoom`, `Count`, `GetRoomInfo`, `GetSingleChatHistory`, `GetRoomHistory`
+
+---
+
+### Session: Added Image Message Support
+
+**Feature: Image Message Uploads and Delivery**
+- Users can now upload images and send image messages in single chat and room chat
+- Images are stored in MinIO object storage with automatic bucket creation
+- Supports JPEG, PNG, GIF, and WebP formats up to 10MB
+
+**docker-compose.yml**
+- Added MinIO service (minio/minio:latest) on 172.28.0.14
+- Added ports 9000 (API) and 9001 (console) for MinIO
+- Added `minio-data` volume for persistent storage
+- Updated API service to depend on MinIO and added minio extra_host
+
+**config/config.go**
+- Added `CommonMinIO` struct with endpoint, accessKeyId, secretAccessKey, bucketName, useSSL
+- Added `ContentTypeText`, `ContentTypeImage`, and `MaxImageSizeBytes` constants
+- Updated `Common` struct to include `CommonMinIO`
+
+**config/{dev,staging,prod}/common.toml**
+- Added `[common-minio]` section with MinIO connection settings
+
+**db/db.go**
+- Added `ContentType` field to Message struct for database migration
+
+**logic/dao/message.go**
+- Added `ContentType` field to Message struct (default: "text")
+
+**proto/logic.go**
+- Added `ContentType` field to `Send`, `SendTcp`, and `MessageItem` structs
+
+**api/handler/upload.go** (new file)
+- Created `InitMinioClient()` to initialize MinIO client and create bucket
+- Created `UploadImage()` handler for multipart form image uploads
+- Validates file size (max 10MB) and content type (jpeg/png/gif/webp)
+- Generates unique filenames with date-based paths (YYYY/MM/uuid.ext)
+
+**api/handler/push.go**
+- Added `ContentType` field to `FormPush` and `FormRoom` structs
+- Updated `Push()` and `PushRoom()` to pass contentType to RPC
+
+**api/router/router.go**
+- Added route `POST /push/uploadImage` for image uploads
+
+**api/chat.go**
+- Added MinIO client initialization on API service startup
+
+**logic/rpc.go**
+- Updated `Push()` to save ContentType to database
+- Updated `PushRoom()` to save ContentType to database
+- Updated `GetSingleChatHistory()` to return ContentType in response
+- Updated `GetRoomHistory()` to return ContentType in response
+
+**go.mod**
+- Added `github.com/minio/minio-go/v7` dependency
+
+**tests/helpers/api_client.go**
+- Added `PushWithContentType()` for sending messages with content type
+- Added `PushRoomWithContentType()` for room messages with content type
+
+**tests/integration/image_message_test.go** (new file)
+- Test image upload success
+- Test invalid image type rejection
+- Test oversized image rejection
+- Test sending image message (single chat)
+- Test sending image message (room chat)
+- Test image message appears in history with correct contentType
+
+**scripts/feat-image-message.sh** (new file)
+- Functional test script for image message feature
+- Tests user registration, image upload, message sending, and history retrieval
+
+---
+
+## 2026-01-25
+
+### Session: Added Message Persistence and History API
+
+**Feature: Chat Message Persistence**
+- Messages are now persisted to SQLite database before delivery
+- Supports both single chat and room messages
+- Synchronous persistence ensures messages are saved reliably
+
+**logic/dao/message.go** (new file)
+- Created `Message` model with fields: Id, FromUserId, FromUserName, ToUserId, ToUserName, RoomId, MessageType, Content, CreateTime
+- Added `Add()` method for inserting messages
+- Added `GetSingleChatHistory()` for retrieving chat history between two users
+- Added `GetRoomHistory()` for retrieving room message history
+
+**db/db.go**
+- Migrated from SQLite to PostgreSQL
+- Added `User` struct for auto-migration
+- Added `Message` struct for auto-migration
+- Added auto-migration for user and message tables on database initialization
+- Added connection pool configuration (maxIdleConns, maxOpenConns, connMaxLifetime)
+
+**config/config.go**

+**config/{dev,staging,prod}/common.toml**
+- Added `[common-postgresql]` section with host, port, user, password, dbname, sslmode, connection pool settings
+
+**docker-compose.yml**
+- Added PostgreSQL service (postgres:15-alpine) on 172.28.0.13
+- Added `postgres-data` volume for data persistence
+- Updated logic service to depend on postgres
+
+**logic/rpc.go**
+- Modified `Push()` to persist single chat messages before publishing to RabbitMQ
+- Modified `PushRoom()` to persist room messages before publishing to RabbitMQ
+- Added `GetSingleChatHistory()` RPC method for retrieving single chat history
+- Added `GetRoomHistory()` RPC method for retrieving room message history
+
+**proto/logic.go**
+- Added `GetSingleChatHistoryRequest` with CurrentUserId, OtherUserId, Limit, Offset
+- Added `GetRoomHistoryRequest` with RoomId, Limit, Offset
+- Added `MessageItem` for representing messages in responses
+- Added `GetMessageHistoryResponse` with Code and Messages array
+
+**api/handler/message.go** (new file)
+- Created `GetSingleChatHistory()` HTTP handler
+- Created `GetRoomHistory()` HTTP handler
+
+**api/rpc/rpc.go**
+- Added `GetSingleChatHistory()` RPC client method
+- Added `GetRoomHistory()` RPC client method
+
+**api/router/router.go**
+- Added route `POST /push/history/single` for single chat history
+- Added route `POST /push/history/room` for room chat history
+
