Problems solved by technology

This not only increases the programmer's burden, but also is not conducive to the automation of the variable tracking process
Also, the execution of the program may be interrupted many times before the source of the abnormal change in the value of the variable is found

Abstract

The invention relates to a method and a system for variable tracking in program debugging. An embodiment discloses the method for variable tracking in program debugging. The method comprises the steps of determining a to-be-tracked first variable and a to-be-monitored first expression associated with the first variable; performing reverse scanning on a debugged program code to search for an assignment expression used for performing assignment on the first variable; and in response to the found assignment expression, setting a monitoring point associated with the first expression after an assignment statement with the assignment expression to check whether the first expression is satisfied or not. The corresponding system is further described.

Description

technical field [0001] Embodiments of the present invention generally relate to the field of program development, and in particular to methods and devices for variable tracking in program debugging. Background technique [0002] During the program development process, the programmer needs to debug the compiled program to find syntax and / or logic errors in the program source code. A debugger is a common tool for performing debugging. For example, specialized debuggers are often provided in integrated development environments (IDEs). It is often necessary to perform variable tracking during debugging. [0003] Specifically, during debugging, programmers often need to confirm whether the value of a given variable is within a reasonable range. Currently, it is possible to use watchpoints to track the value of variables. Taking C or C++ language as an example, programmers can use statements such as assert to stop the running of the program at a specified position. Then, the ...
