Problems solved by technology

With the development of new functions, related software codes gradually increase, and the complexity of the codes also increases. Therefore, the difficulty of debugging the program to solve the cause of program bugs is also greatly increased.
[0004] The traditional program debugging method used in the prior art is based on the GDB debugging tool using ptrace for breakpoint debugging. By setting breakpoints to debug the program step by step, the execution efficiency of the program will be affected during the debugging process.
For storage devices, the impact on application execution efficiency during debugging is strictly not allowed, which will seriously affect the storage services provided by the system.

Abstract

The invention discloses a program debugging method. The program debugging method comprises the steps of mapping data files of a business process to a memory space of a debugging process in an mmap manner; and parsing and debugging the data files according to resource files and symbol table files of the business process by utilization of a BE binary editor, wherein the resource files and the symbol table files are generated during a compilation process of the business process in advance. By mapping the data files of the business process to the debugging process, the data files can be parsed to complete debug according to the resource files and the symbol table files without influencing execution efficiency of the business process. The invention also discloses a program debugging apparatus having the above beneficial effect.

Description

technical field [0001] The present application relates to the technical field of storage, and in particular to a program debugging method and device. Background technique [0002] With the rapid development of information technology, technological innovation in the field of storage technology is also changing with each passing day, quietly changing people's production and lifestyle. [0003] At present, a single disk storage device has gradually transformed into a more complex intelligent storage device system, and software development is based on the Linux system to meet the production requirements of modern society. With the development of new functions, the number of related software codes gradually increases, and the complexity of the codes also increases. Therefore, the difficulty of debugging the program to solve the cause of program bugs is also greatly increased. [0004] The traditional program debugging method adopted in the prior art is based on the breakpoint de...
