Abstract

The invention discloses a method and an apparatus for determining a memory leakage position, and belongs to the technical field of computers. The method comprises the steps of obtaining a memory address applied through a dynamic memory application function when it is detected that the dynamic memory application function is called in a process of executing a target program, obtaining a call relation of current upper call functions of the dynamic memory application function, and in a memory occupation database, recording a corresponding relationship between the memory address and the call relation; and according to the recorded call relation, determining the memory leakage position. By adopting the method and the apparatus, the efficiency of searching for code positions of memory leakage can be improved.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method and a device for determining the location of a memory leak. Background technique [0002] For applications that do not know how much memory space to apply for in advance, they will dynamically apply for memory at runtime. When the memory is used up, the dynamically applied memory should be released. The application memory is not released in time after the memory is used up, resulting in the memory being occupied all the time. [0003] Technicians can instrument applications. In the prior art, the method for detecting whether the application program has a memory leak is to record the function that calls the dynamic memory application function during the running of the application program. For example, when the function a calls the dynamic memory application function, the application program will record a Functions and their corresponding requested memory. After the a...
