Self-Debugging Software via Virtual System Mirroring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current software systems lack effective self-debugging capabilities, leading to system failures from external faults and internal bugs, with existing fault-tolerant and self-stabilizing systems being difficult to build and error-prone, and formal verification methods not directly resulting in robust self-debugging systems.
Innovation Solution
A generative approach to building self-debugging systems that mimics nature's immune response strategy, involving recognition, classification, response, and protection phases, using a reflective, correct-by-construction method to generate provably correct code that can adapt to faults and environmental changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If formal verification methods are used to analyze fault-tolerant algorithms, then algorithm correctness is improved, but the gap between analyzed algorithms and deployed systems increases
Solution Approach 1:
The patent creates a virtual copy of the software system that mirrors the actual system's structure and behavior. This virtual copy can be formally verified without affecting the real system, allowing verification results to be directly applied to the deployed system. The virtual copy includes virtual processing devices, memory, and storage that replicate the actual system's components, enabling formal analysis while maintaining direct applicability to the real system.
Solution Approach 2:
The patent introduces a virtual system as an intermediary between formal verification methods and the actual deployed system. This virtual system serves as a bridge that can be formally analyzed while accurately representing the real system's behavior, thereby eliminating the gap between theoretical verification and practical deployment.
2Reliability
If fault-tolerant and self-stabilizing systems are built, then system reliability is improved, but the systems become difficult to build and error-prone
Solution Approach 1:
The patent divides the software system into modular components including virtual processing devices, memory modules, and storage devices. Each component can be independently designed, verified, and assembled. This modular approach simplifies the building process by allowing developers to work with smaller, more manageable units rather than constructing complex fault-tolerant systems as a whole.
Solution Approach 2:
The patent performs formal verification of individual components and their interactions before assembling the complete system. By verifying correctness in advance during the design phase rather than after deployment, the system achieves fault tolerance without requiring complex runtime monitoring or self-healing mechanisms that would increase building difficulty.
3Reliability
If self-debugging capabilities are added to software systems, then fault recovery is improved, but system complexity increases
Solution Approach 1:
The patent implements self-diagnosis and self-correction capabilities within the virtual system that automatically detect and respond to faults without external intervention. The system monitors its own state, identifies errors, and executes recovery procedures autonomously, providing fault recovery while keeping the complexity manageable through automated rather than manual debugging processes.

AI summary
In one embodiment the present invention includes a computer-implemented method of self debugging a computer program operating in a distributed processing environment. The method includes detecting a fault in a plurality of processing devices and classifying the fault according to fault classifications. The fault classifications have corresponding responses. The method further includes executing one of the responses in accordance with the fault having been classified. The method further includes revising the computer program according to the response. This method may be embodied in a computer program or executed by a computer system. In this manner, the computer program performs self debugging.
