A model install is limited to the entries of the model list. The legacy
server compared save_path, base and filename with the list, but not the
url the file is downloaded from, so a request with a listed name and
another url was queued as given. The glob server lost the list check,
and the check for formats other than .safetensors, when its routes
moved to data models (0be0a2e6), so it queued and downloaded whatever a
request named.
Compare the url in both servers; for the legacy server this is the port
of #3428. In the glob server, run both checks in the worker, which
queue/install_model and queue/task both reach. A default channel list
without models counts as empty there, so the model is refused and the
worker keeps running.
ComfyUI-Manager: Core Backend (glob)
This directory contains the Python backend modules that power ComfyUI-Manager, handling the core functionality of node management, downloading, security, and server operations.
Directory Structure
- glob/ - code for new cacheless ComfyUI-Manager
- legacy/ - code for legacy ComfyUI-Manager
Core Modules
- manager_core.py: The central implementation of management functions, handling configuration, installation, updates, and node management.
- manager_server.py: Implements server functionality and API endpoints for the web interface to interact with the backend.
Specialized Modules
- share_3rdparty.py: Manages integration with third-party sharing platforms.
Architecture
The backend follows a modular design pattern with clear separation of concerns:
- Core Layer: Manager modules provide the primary API and business logic
- Utility Layer: Helper modules provide specialized functionality
- Integration Layer: Modules that connect to external systems
Security Model
The system implements a comprehensive security framework with multiple levels:
- Block: Highest security - blocks most remote operations
- High: Allows only specific trusted operations
- Middle: Standard security for most users
- Normal-: More permissive for advanced users
- Weak: Lowest security for development environments
Implementation Details
- The backend is designed to work seamlessly with ComfyUI
- Asynchronous task queuing is implemented for background operations
- The system supports multiple installation modes
- Error handling and risk assessment are integrated throughout the codebase
API Integration
The backend exposes a REST API via manager_server.py that enables:
- Custom node management (install, update, disable, remove)
- Model downloading and organization
- System configuration
- Snapshot management
- Workflow component handling
