Method and device for determining reference relationship of memory objects

Abstract

This application discloses a method and device for determining the reference relationship of memory objects. This application can obtain the memory snapshot information at the target time point during the running of the target application. The memory snapshot information includes the value and address of the memory object, and then based on A memory object When referencing the B memory object, the value of the A memory object contains the address of the B memory object. Match the value of each memory object in the memory snapshot information with the addresses of other memory objects in the memory snapshot information. According to the matching result Determine the reference relationship between each memory object. By determining the reference relationship between each memory object, it can help developers find the essential reason why the redundant memory objects are not destroyed, cancel the redundant reference relationship at the code layer, and optimize the code.

Description

technical field [0001] The present application relates to the technical field of memory detection, and more specifically, to a method and device for determining a memory object reference relationship. Background technique [0002] With the development of Internet technology, various types of applications have sprung up, providing users with diversified network services, such as video services, game services, webcast services, etc., greatly enriching users' lives. [0003] The application will dynamically apply for memory space during the running process, and as the application process runs, the applied memory space should be released in time if it is no longer used, so as to avoid the infinite growth of application memory and memory leaks. For a memory object, if it is referenced by other memory objects, the memory object cannot be destroyed by the garbage collection mechanism GC. That is, the referenced memory object cannot be destroyed. For most applications on the marke...

AI Technical Summary

Problems solved by technology

For a memory object, if it is referenced by other memory objects, the memory object will not be destroyed by the garbage collection mechanism GC

That is, the referenced memory object cannot be destroyed

For most applications on the market, due to imperfect code writing, there may be some reference relationships between memory objects that cannot be canceled in time, resulting in memory objects that cannot be destroyed in time
