+Content Type Detection and Stream Classification
+
+This module provides intelligent content-type detection for changedetection.io.
+It addresses the common problem where HTTP Content-Type headers are missing, incorrect,
+or too generic, which would otherwise cause the wrong processor to be used.
+
+The guess_stream_type class combines:
+1. HTTP Content-Type headers (when available and reliable)
+2. Python-magic library for MIME detection (analyzing actual file content)
+3. Content-based pattern matching for text formats (HTML tags, XML declarations, etc.)
+
+This multi-layered approach ensures accurate detection of RSS feeds, JSON, HTML, PDF,
+plain text, CSV, YAML, and XML formats - even when servers provide misleading headers.
+
+Used by: processors/text_json_diff/processor.py and other content processors

+    Ultra-reliable priority queue using janus for async/sync bridging.

+    CRITICAL DESIGN NOTE: Both sync_q and async_q are required because:
+    - sync_q: Used by Flask routes, ticker threads, and other synchronous code
+    - async_q: Used by async workers (the actual fetchers/processors) and coroutines
+    
+    DO NOT REMOVE EITHER INTERFACE - they bridge different execution contexts:
+    - Synchronous code (Flask, threads) cannot use async methods without blocking
+    - Async code cannot use sync methods without blocking the event loop
+    - janus provides the only safe bridge between these two worlds
+    
+    Attempting to unify to async-only would require:
+    - Converting all Flask routes to async (major breaking change)
+    - Using asyncio.run() in sync contexts (causes deadlocks)
+    - Thread-pool wrapping (adds complexity and overhead)
+    
+    Minimal implementation focused on reliability:
+    - Pure janus for sync/async bridge
+    - Thread-safe priority ordering

+# Real-time Socket.IO Implementation
+
+This directory contains the Socket.IO implementation for changedetection.io's real-time updates.
+
+## Architecture Overview
+
+The real-time system provides live updates to the web interface for:
+- Watch status changes (checking, completed, errors)
+- Queue length updates  
+- General statistics updates
+
+## Current Implementation
+
+### Socket.IO Configuration
+- **Async Mode**: `threading` (default) or `gevent` (optional via SOCKETIO_MODE env var)
+- **Server**: Flask-SocketIO with threading support
+- **Background Tasks**: Python threading with daemon threads
+
+### Async Worker Integration
+- **Workers**: Async workers using asyncio for watch processing
+- **Queue**: AsyncSignalPriorityQueue for job distribution
+- **Signals**: Blinker signals for real-time updates between workers and Socket.IO
+
+### Environment Variables
+- `SOCKETIO_MODE=threading` (default, recommended)
+- `SOCKETIO_MODE=gevent` (optional, has cross-platform limitations)
+
+## Architecture Decision: Why Threading Mode?
+
+### Previous Issues with Eventlet
+**Eventlet was completely removed** due to fundamental compatibility issues:
+
+1. **Monkey Patching Conflicts**: `eventlet.monkey_patch()` globally replaced Python's threading/socket modules, causing conflicts with:
+   - Playwright's synchronous browser automation
+   - Async worker event loops
+   - Various Python libraries expecting real threading
+
+2. **Python 3.12+ Compatibility**: Eventlet had issues with newer Python versions and asyncio integration
+
+3. **CVE-2023-29483**: Security vulnerability in eventlet's dnspython dependency
+
+### Current Solution Benefits
+✅ **Threading Mode Advantages**:
+- Full compatibility with async workers and Playwright
+- No monkey patching - uses standard Python threading
+- Better Python 3.12+ support
+- Cross-platform compatibility (Windows, macOS, Linux)
+- No external async library dependencies
+- Fast shutdown capabilities
+
+✅ **Optional Gevent Support**:
+- Available via `SOCKETIO_MODE=gevent` for high-concurrency scenarios
+- Cross-platform limitations documented in requirements.txt
+- Not recommended as default due to Windows socket limits and macOS ARM build issues
+
+## Socket.IO Mode Configuration
+
+### Threading Mode (Default)
+```python
+# Enabled automatically
+async_mode = 'threading'
+socketio = SocketIO(app, async_mode='threading')
+```
+
+### Gevent Mode (Optional)
+```bash
+# Set environment variable
+export SOCKETIO_MODE=gevent
+```
+
+## Background Tasks
+
+### Queue Polling
+- **Threading Mode**: `threading.Thread` with `threading.Event` for shutdown
+- **Signal Handling**: Blinker signals for watch state changes
+- **Real-time Updates**: Direct Socket.IO `emit()` calls to connected clients
+
+### Worker Integration
+- **Async Workers**: Run in separate asyncio event loop thread
+- **Communication**: AsyncSignalPriorityQueue bridges async workers and Socket.IO
+- **Updates**: Real-time updates sent when workers complete tasks
+
+## Files in This Directory
+
+- `socket_server.py`: Main Socket.IO initialization and event handling
+- `events.py`: Watch operation event handlers  
+- `__init__.py`: Module initialization
+
+## Production Deployment
+
+### Recommended WSGI Servers
+For production with Socket.IO threading mode:
+- **Gunicorn**: `gunicorn --worker-class eventlet changedetection:app` (if using gevent mode)
+- **uWSGI**: With threading support
+- **Docker**: Built-in Flask server works well for containerized deployments
+
+### Performance Considerations
+- Threading mode: Better memory usage, standard Python threading
+- Gevent mode: Higher concurrency but platform limitations
+- Async workers: Separate from Socket.IO, provides scalability
+
+## Environment Variables
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `SOCKETIO_MODE` | `threading` | Socket.IO async mode (`threading` or `gevent`) |
+| `FETCH_WORKERS` | `10` | Number of async workers for watch processing |
+| `CHANGEDETECTION_HOST` | `0.0.0.0` | Server bind address |
+| `CHANGEDETECTION_PORT` | `5000` | Server port |
+
+## Debugging Tips
+
+1. **Socket.IO Issues**: Check browser dev tools for WebSocket connection errors
+2. **Threading Issues**: Monitor with `ps -T` to check thread count  
+3. **Worker Issues**: Use `/worker-health` endpoint to check async worker status
+4. **Queue Issues**: Use `/queue-status` endpoint to monitor job queue
+5. **Performance**: Use `/gc-cleanup` endpoint to trigger memory cleanup
+
+## Migration Notes
+
+If upgrading from eventlet-based versions:
+- Remove any `EVENTLET_*` environment variables
+- No code changes needed - Socket.IO mode is automatically configured
+- Optional: Set `SOCKETIO_MODE=gevent` if high concurrency is required and platform supports it
