Debugging Tool Execution Capture Replay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of modern systems, including software and external interactions, makes debugging efforts lengthy and challenging, requiring thorough data collection and analysis, and is influenced by programming languages and tool utilization.
Innovation Solution
A debugging tool captures and replays the memory state of an application and its input/output interactions with external systems, allowing configurable capture points, recording external system calls, and enabling stepping through execution paths to analyze code paths, variable values, and external system interactions.

Engineering Contradiction Analysis
1Measurement precision
If traditional debugging methods are used with manual data collection and analysis, then thorough exploration of execution paths can be achieved, but the time required for debugging increases significantly
Solution Approach 1:
The system performs preliminary actions by capturing and recording execution data, memory states, and external system interactions before the actual debugging analysis begins. The debugger automatically collects trace information, variable values, and execution paths in advance, so that when debugging is needed, the data is already prepared and can be immediately analyzed without manual data collection.
Solution Approach 2:
The system creates a copy of the execution trace and memory state data that can be replayed and analyzed independently from the original running system. This copied execution data allows thorough analysis of what happened during execution without interfering with the actual system operation, enabling multiple analysis passes and detailed examination of execution paths.
2Reliability
If detailed monitoring of execution paths is performed, then identification of errors can be improved, but the complexity of the debugging process increases
Solution Approach 1:
The debugger performs self-service by automatically capturing, recording, and analyzing execution data without requiring manual intervention for each monitoring step. The system autonomously traces execution paths, records memory states at configurable points, and identifies external system interactions, thereby reducing the operational complexity while maintaining detailed monitoring capabilities.
Solution Approach 2:
The system merges multiple monitoring functions into a unified debugging process. Instead of separately tracking execution paths, memory states, and external interactions, the system combines all these monitoring activities into a single integrated capture and replay mechanism, simplifying the overall debugging process while maintaining comprehensive monitoring.
3Measurement precision
If manual data collection and analysis is performed, then comprehensive path analysis can be achieved, but productivity decreases
Solution Approach 1:
The system maintains continuous useful action by persistently capturing and recording execution data throughout the entire program run. The debugger continuously monitors execution paths, memory states, and external interactions without interruption, ensuring that complete path analysis data is collected automatically during normal operation rather than requiring intermittent manual data gathering.
Solution Approach 2:
The system replaces manual mechanical data collection and analysis processes with automated electronic capturing and replay mechanisms. Instead of programmers manually tracing execution paths and collecting data, the system uses automated tracing infrastructure to capture execution traces, memory states, and interaction logs, significantly improving productivity while maintaining analysis completeness.
Data Source
AI summary
A debugging tool is provided that is capable of recording code paths taken during a program's execution, and along the way capture the memory state at configurable points in time such as function exits or statements. The tool also records interactions with external systems like a database, and captures which statements resulted in interactions with these systems. An analysis of the output of the debugging tool enables a developer to understand which part of the code executed; what the value of relevant variables were at configurable points in time; and which code statements correlate to which interactions with external systems.
