Solution Overview

Problem

Debugging tools face challenges in providing secure and efficient debugging capabilities across different communication interfaces for multithreaded systems, particularly when integrating with web servers and multi-model databases, due to the complexity of socket connections and security risks in single-threaded systems.

Innovation Solution

A debug adapter that converts debug requests into HTTP requests, using JSON format for communication between the debugger and the server, ensuring secure and concurrent execution of debug operations through HTTP protocol, and leveraging the V8 JavaScript engine's Inspector protocol for multithreaded environments, with privilege checks and REST APIs for secure access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If socket connections are used for debugging in single-threaded systems, then debugging functionality is achieved, but security risks increase and implementation becomes difficult for multithreaded systems

Engineering Contradiction:
Improvedebugging functionalityVSAvoidsecurity risks
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an HTTP-based intermediary layer between the debugging tool and the multithreaded system. Instead of using direct socket connections, the debug adapter communicates through HTTP requests and responses, which provides built-in security mechanisms and protocol standardization. This intermediary approach maintains debugging functionality while eliminating the security risks associated with direct socket connections in multithreaded environments.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If socket connections are used for debugging, then debugging capability is provided, but implementation difficulty increases for multithreaded systems

Engineering Contradiction:
Improvedebugging capabilityVSAvoidimplementation difficulty
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent implements a universal HTTP-based debugging interface that can work across multithreaded systems. By using standard HTTP protocols and JSON formatting, the debug adapter becomes universally applicable to different multithreaded architectures without requiring system-specific socket connection implementations. This universal approach significantly reduces implementation difficulty while maintaining debugging capability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If distinct communication interfaces are used for debugging tools, web servers, and databases, then system modularity is maintained, but debugging across interfaces becomes complex

Engineering Contradiction:
Improvesystem modularityVSAvoiddebugging complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The debug adapter serves as an intermediary that translates between different communication interfaces. It receives debugging requests from the debugging tool, converts them into appropriate HTTP requests for the web server or database, and translates responses back into debugging format. This intermediary layer maintains system modularity while simplifying cross-interface debugging by handling interface translation automatically.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Object-affected harmful factors

If privilege checks are implemented for debug requests, then system security is improved, but processing time increases

Engineering Contradiction:
Improvesystem securityVSAvoidprocessing time
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The patent implements privilege checks as preliminary actions that are performed once during user authentication and session establishment. The system pre-determines which users have debugging privileges and stores this information in session data or authentication tokens. When debug requests are received, the system checks against pre-established privilege criteria rather than performing full authentication checks for each request, thereby maintaining security while minimizing processing time overhead.

Inventive Principle:
Principle #10Preliminary action

AI summary

A non-transitory computer readable storage medium has instructions executed by a processor to receive a debug adapter request. A HyperText Transfer Protocol (HTTP) request is generated from the debug adapter request. A debug request is derived from the HTTP request. Privilege to submit the debug request is confirmed. A string serialized JavaScript Object Notation (JSON) debug request is submitted to a JavaScript Engine. A string serialized JSON debug response from the JavaScript Engine is received. A JSON debug response is formed from the string serialized JSON debug response. An HTTP response is prepared from the JSON debug response. A debug adapter response based upon the HTTP response is submitted.
