Dr.Lt.Data 573742e800 v4: Settle which OpenCV package provides cv2 after the repair (#3493)
The package installed last provides cv2. The repair ranked the
packages with the GUI above the headless ones, so on a Linux without
the graphics libraries it replaced a working headless cv2 with one
that cannot be imported.

- Install a headless package after one with the GUI, and within each
  kind the one with the contrib modules last: opencv-python,
  opencv-contrib-python, opencv-python-headless,
  opencv-contrib-python-headless
- The package that ends up providing cv2 follows from this order alone,
  not from which package was the older one
- Update the tests and correct the CHANGELOG sentence

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:

  1. Core Layer: Manager modules provide the primary API and business logic
  2. Utility Layer: Helper modules provide specialized functionality
  3. 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
