Program debugging system with program analysis function

Abstract

The invention relates to a program debugging system with a program analysis function. The program debugging system comprises debugging steps as follows; establishing connection with a target virtual machine, conducting standard debugging and conducting expansion debugging. The program debugging system is not limited to the traditional program debugging mode any longer; debugging is not to only analyze the current running status of a program any longer; debugging personnel can check a complete executing process of the program; debugging is convenient; and the program can be understood conveniently; the program debugging system can record application classes and application methods in one execution of the program and reduce attention ranges of the debugging personnel. When the system conducts dynamic program slicing, the program is not required to be traced and control dependence analysis is only conducted on methods concerned in the program executing process; the algorithm efficiency can be improved; and the precision of slicing can be improved according to stack information and control dependence relationship.

Description

technical field [0001] The invention relates to a program debugging system, in particular to a program debugging system with program analysis function for analyzing and understanding programs in the process of software debugging and system maintenance. Background technique [0002] Program debugging is the process of testing the compiled program manually or by compiling the program before putting it into actual operation, and correcting grammatical and logical errors. This is an essential step to ensure the correctness of computer information systems. As the scale of software increases day by day, traditional debugging techniques cannot effectively deal with complex and large programs. Large-scale application systems usually have millions of lines of code, and program developers often cannot quickly understand the code in the program, which brings great difficulties to program debugging and maintenance. [0003] In program debugging, the most common job is to find an error...

Problems solved by technology

[0005] In order to solve the problem that the existing debugging technology cannot effectively deal with complex large-scale programs and program developers often cannot quickly understand the codes in the program, the present invention provides a A program debugging system with program analysis function. The program debugging system is no longer limited to the traditional program debugging method, so that debugging is no longer just to analyze the current running state of the program. The program debugging system can record from the beginning of the program to the current state The debugger can view the complete execution process of the program, and debug and understand the program conveniently; the program debugging system can also record t
