Detection methods and devices for memory leaks

Abstract

The embodiment provides detection methods and devices for memory leaks,which is used to automatically detected the technical results of memory leaks. The method comprises a memory test module monitors each work Activity for a target application; when the any exit of the activity described is monitored, and described the Activity of one or more references are not cleared, a memory leak of the described target application will be determined; one or more references that are not cleared are dumped to one or more binary dump file hprof files of the target application one by one, the hprof file is capable of representing a reference relation to a reference, the referenced chain for each of the referenced references is identified, the chain of references that cause memory leaks from one or more referenced chains can be identified.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method and device for detecting memory leaks. Background technique [0002] A memory leak means that a function module continues to apply for memory space. After the function ends, the memory space requested by the function cannot be recovered. The emergence of memory leaks will cause the memory to continue to increase, and eventually the system will forcibly end the application and release the memory. Forcibly ending the application will cause the application to exit abnormally and reduce the user experience. [0003] In the prior art, memory leaks are detected through manual testing. However, it is difficult to test all memory leaks due to the contingency of manual testing. Moreover, there are differences between the manual testing environment and the actual application environment, and manual testing must be completed before it is put into the market, so manual testing ...

Problems solved by technology

However, it is difficult to test all memory leaks due to the contingency of manual testing

Moreover, there are differences between the manual testing environment and the actual application environment, and manual testing must be completed before it is put into the market, so manual testing is difficult to restore the actual situation of memory leaks

[0004] Therefore, because the existing technology relies on manual detection of memory leaks, the cycle of detecting memory leaks and solving memory leaks is long
