It replaces the need for git-based JIT enablement methods and provides a unified API for both iOS 16 and iOS 17+ devices. +This is the Flask backend for SideStore, which provides JIT enablement for iOS apps. -## Features +## Setup -- Secure device registration with JWT authentication -- JIT enablement for iOS 16 and below -- JIT enablement for iOS 17+ -- Session tracking for JIT operations -- Health check endpoint -- Device management +1.

Clone this repository -2. Install dependencies: - ``` - pip install -r requirements.txt - ``` +The backend requires specific versions of dependencies to work correctly: -## Development +- `pymobiledevice3==2.30.0`: Version 2.31.0+ breaks the JIT functionality due to changes in the API. +- `construct==2.10.69`: Required for pymobiledevice3 2.30.0 to work properly. Newer versions cause 'stream.tell()' errors. -Run the development server: +If you encounter the error `ModuleNotFoundError: No module named 'pymobiledevice3.services.debugserver'`, the backend will automatically use a compatibility module that implements the missing functionality. -```bash -export FLASK_ENV=development -export FLASK_APP=app.py -flask run --host=0.0.0.0 --port=5000 -``` +### Compatibility Module -## Production Deployment +The `pymobiledevice3_compat` directory contains a compatibility layer that implements the missing `debugserver` module. This allows the backend to work with newer versions of pymobiledevice3 if needed, although it's still recommended to use the pinned versions in requirements.txt. -### Using Docker +## API Endpoints -1. Build the Docker image: - ``` - docker build -t sidestore-jit-backend . - ``` +- `/health`: Check if the server is running +- `/register`: Register a device +- `/enable-jit`: Enable JIT for an app +- `/session/`: Get the status of a JIT enablement session +- `/devices`: List registered devices and active sessions -2.

Run with Gunicorn: +2. If you're using a system-wide Python installation, you might need to use the specific Python executable: ``` - gunicorn --bind 0.0.0.0:5000 --workers 4 production_app:app + /Library/Developer/CommandLineTools/usr/bin/python3 -m pip install pymobiledevice3==2.30.0 construct==2.10.69 ``` -## API Endpoints - -### Health Check -- `GET /health` - - Returns the health status of the server - -### Device Registration -- `POST /register` - - Registers a device and returns a JWT token - - Request body: `{"udid": "device_udid", "device_name": "iPhone"}` - - Response: `{"token": "jwt_token", "message": "Device registered successfully"}` - -### Enable JIT -- `POST /enable-jit` - - Enables JIT for a specific app - - Requires JWT authentication - - Request body: `{"bundle_id": "com.example.app", "ios_version": "16.5"}` - - Response: `{"status": "JIT enabled", "session_id": "uuid", "message": "Enabled JIT for 'com.example.app'!"}` - -### Session Status -- `GET /session/` - - Gets the status of a JIT enablement session - - Requires JWT authentication - - Response: `{"status": "completed", "started_at": 1617293932, "bundle_id": "com.example.app"}` - -### Device Statistics -- `GET /devices` - - Gets statistics about registered devices and active sessions - - Response: `{"registered_devices": 10, "active_sessions": 5}` - -## Security Considerations - -- In production, always use HTTPS -- Set a strong JWT_SECRET_KEY -- Consider implementing rate limiting -- Use a proper database for device and session storage -- Implement proper access controls for admin endpoints - -## License - -This project is licensed under the MIT License - see the LICENSE file for details. +3.
