The install-denial diagnostics named the wrong gate, sending users to settings that could not resolve their denial: - SECURITY_MESSAGE_FLAG_GIT_URL / _FLAG_PIP omitted the loopback half of the flag-AND-loopback predicate, telling users to enable a flag that was often already enabled. They now state both conditions, print the live --listen value at every emission site, and explain that both values are read once at startup (stop the server, edit, then start). - SECURITY_MESSAGE_MIDDLE_OR_BELOW instructed setting security_level to 'middle', a value that does not exist; it now names only real values (any level other than 'strong': normal, normal-, weak). - The blocked-risk arm reused SECURITY_MESSAGE_GENERAL, blaming security_level although no value of it can help there; it now emits a dedicated SECURITY_MESSAGE_BLOCKED_RISK stating this is not a configuration problem. - SECURITY_MESSAGE_NORMAL_MINUS_MODEL now names its loopback-listener condition and the same restart guidance. - The js/common.js dedicated-403 messages mirror the loopback clause.
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.
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.
- manager_downloader.py: Handles downloading operations for models, extensions, and other resources.
- manager_util.py: Provides utility functions used throughout the system.
Specialized Modules
- cm_global.py: Maintains global variables and state management across the system.
- cnr_utils.py: Helper utilities for interacting with the custom node registry (CNR).
- git_utils.py: Git-specific utilities for repository operations.
- node_package.py: Handles the packaging and installation of node extensions.
- security_check.py: Implements the multi-level security system for installation safety.
- 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
