daohp c05434aab1 refactor: Update session management and logging in query routes
- Removed legacy import statements and integrated session history management directly into query routes.
- Enhanced logging functionality to capture session details and errors more effectively.
- Updated README.md to comment out the environment variable setup command for clarity.

🧪 Session History Testing

Test 1: Create Session

curl -X POST http://localhost:9621/history/sessions \
  -H "Content-Type: application/json" \
  -H "X-User-ID: test@example.com" \
  -H "Authorization: Bearer test-token" \
  -d '{"title": "Test Session"}'

Response:

{
    "id": "ed4422e4-6fd6-4575-81ba-67598bdfeafd",
    "title": "Test Session",
    "created_at": "2025-12-03T07:40:43.952573Z",
    "last_message_at": "2025-12-03T07:40:43.952573Z"
}

Test 2: List Sessions

curl http://localhost:9621/history/sessions \
  -H "X-User-ID: test@example.com" \
  -H "Authorization: Bearer test-token"

Response:

[
    {
        "id": "ed4422e4-6fd6-4575-81ba-67598bdfeafd",
        "title": "Test Session",
        "created_at": "2025-12-03T07:40:43.952573Z",
        "last_message_at": "2025-12-03T07:40:43.952573Z"
    }
]

🎯 Access Points

Local Access

Session History Endpoints

  • POST /history/sessions - Create session
  • GET /history/sessions - List sessions
  • GET /history/sessions/{id}/history - Get messages
  • DELETE /history/sessions/{id} - Delete session

🔧 Configuration Summary

What Was Simplified

Before (Complex):

SESSION_HISTORY_ENABLED=true
SESSION_POSTGRES_HOST=localhost
SESSION_POSTGRES_PORT=5433
SESSION_POSTGRES_USER=session_user
SESSION_POSTGRES_PASSWORD=session_password
SESSION_POSTGRES_DATABASE=sessions_db

After (Simple):

# Just use existing POSTGRES_* configuration!
# Session history automatically enabled
# No additional configuration needed

Zero-Config Session History

  • No SESSION_HISTORY_ENABLED variable needed
  • No SESSION_POSTGRES_* variables needed
  • Uses existing POSTGRES_* configuration
  • Automatically creates tables in same database
  • Always enabled by default

📊 Server Configuration

📡 Server: 0.0.0.0:9621
🤖 LLM: gpt-4o-mini (OpenAI)
📊 Embedding: text-embedding-3-small (1536 dims)
💾 Storage:
   ├─ KV: RedisKVStorage
   ├─ Vector: PGVectorStorage
   ├─ Graph: Neo4JStorage
   ├─ Doc Status: PGDocStatusStorage
   └─ Session History: PGVectorStorage (same PostgreSQL)
⚙️  RAG:
   ├─ Language: Vietnamese
   ├─ Chunk Size: 1500
   ├─ Top-K: 40
   └─ Cosine Threshold: 0.2

🎉 Success Highlights

Integration Complete

  1. Session history fully integrated into LightRAG core
  2. Zero additional configuration required
  3. Shares PostgreSQL with other LightRAG data
  4. Tables auto-created on startup
  5. Graceful degradation if PostgreSQL unavailable

Migration from service/ folder

  • Old service/ approach: Separate service, separate config
  • New integrated approach: Built-in, zero config

Simplification Achieved

  • Removed: SESSION_HISTORY_ENABLED
  • Removed: SESSION_POSTGRES_*
  • Removed: SESSION_HISTORY_AVAILABLE check
  • Result: Just works!

🚀 Next Steps

Using Session History

  1. From WebUI:

  2. From API:

    # Create session
    curl -X POST http://localhost:9621/history/sessions \
      -H "Content-Type: application/json" \
      -H "X-User-ID: your@email.com" \
      -H "Authorization: Bearer your-token" \
      -d '{"title": "My Research Session"}'
    
    # Query with session
    curl -X POST http://localhost:9621/query \
      -H "Content-Type: application/json" \
      -d '{
        "query": "What is LightRAG?",
        "session_id": "session-uuid-here"
      }'
    

Verification

Check logs at:

tail -f c:\Users\hauph\.cursor\projects\d-work-LightRAG\terminals\11.txt

Or:

tail -f D:\work\LightRAG\lightrag.log

Database Verification

Connect to PostgreSQL and check tables:

\c lightrag
\dt lightrag_chat*
SELECT * FROM lightrag_chat_sessions_history;
