Embodiment Construction

[0046] The embodiments of the invention provide a method and device for detecting memory leaks, which are used to realize the technical effect of automatically detecting memory leaks.

[0047] In order to solve the above technical problems, the general idea of ​​the technical solution provided by the present invention is as follows:

[0048] In the technical solution of the embodiment of the present invention, the memory detection module monitors each job Activity of the target application, and when any Activity is monitored to exit and one or more references of the Activity are not cleared, the target application is determined There is a memory leak, and then one or more references that have not been cleared are dumped into one or more binary dump files hprof files of the target application. The hprof file can indicate the reference relationship of a reference, and then based on each The hprof file indicates the reference relationship of the references stored in the hprof fil...

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 ...
