From c05434aab1001ba767fe43e71e490edc62b57204 Mon Sep 17 00:00:00 2001 From: daohp Date: Wed, 3 Dec 2025 14:42:37 +0700 Subject: [PATCH] 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. --- MIGRATION_STEPS.md | 191 ++++++++++++++++++++ README.md | 2 +- STARTUP_SUCCESS.md | 251 ++++++++++++++++++++++++++ lightrag/api/routers/query_routes.py | 256 ++++++++++++--------------- lightrag/api/session_database.py | 4 + 5 files changed, 562 insertions(+), 142 deletions(-) create mode 100644 MIGRATION_STEPS.md create mode 100644 STARTUP_SUCCESS.md diff --git a/MIGRATION_STEPS.md b/MIGRATION_STEPS.md new file mode 100644 index 00000000..c02fdf04 --- /dev/null +++ b/MIGRATION_STEPS.md @@ -0,0 +1,191 @@ +# Migration Steps - Session History Integration + +## Current Situation + +You are on the `session_intergrate` branch which still uses the old `service/` folder approach. The new integration code I created uses `lightrag/api/session_*` modules. + +## Quick Fix Applied + +I've updated these files to use the new integrated modules: + +### 1. `lightrag/api/routers/query_routes.py` +Changed imports from: +```python +from app.core.database import SessionLocal +from app.services.history_manager import HistoryManager +``` + +To: +```python +from lightrag.api.session_database import SessionLocal, get_db +from lightrag.api.session_manager import SessionHistoryManager +``` + +### 2. `lightrag/api/session_database.py` +Added SessionLocal alias for backward compatibility: +```python +SessionLocal = lambda: get_session_db_manager().get_session() +``` + +## Steps to Complete Migration + +### 1. Install Dependencies +```bash +cd /d/work/LightRAG +pip install sqlalchemy psycopg2-binary httpx +``` + +### 2. Configure PostgreSQL +Ensure your `.env` file has PostgreSQL configured: +```bash +POSTGRES_HOST=localhost +POSTGRES_PORT=5432 +POSTGRES_USER=postgres +POSTGRES_PASSWORD=your_password +POSTGRES_DATABASE=lightrag_db +``` + +### 3. Start PostgreSQL +If using Docker: +```bash +docker run -d --name postgres \ + -e POSTGRES_USER=postgres \ + -e POSTGRES_PASSWORD=password \ + -e POSTGRES_DB=lightrag_db \ + -p 5432:5432 \ + postgres:16 +``` + +Or use existing PostgreSQL instance. + +### 4. Test Server +```bash +cd /d/work/LightRAG +lightrag-server +``` + +Check logs for: +``` +INFO: Session history database initialized successfully +``` + +### 5.
