Runtime error site analysis tool based on variable tracking
Zhang Tianjion · Journal of Computer Applications · 2014
A runtime error is generated in the course of the program's dynamic execution. When the error occurred, it needs to use traditional debug tools to analyze the cause of the error. For the real execution environment of some exception and multi-thread can not be reproduced, the traditional debug analysis means is not obvious. If the variable information can be captured during the program execution, the runtime error site will be caught, which is used as a basis for analysis of the cause of the error. In this paper, the technology of capture runtime error site based on variable tracking was proposed; it can capture specific variable information according to user needs, and effectively improved the flexibility of access to variable information. Based on it, a tool named Runtime Fault Site Analysis( RFST) was implemented, which could be used to analyze error cause and provide error site and aided analysis approach as well.
