Embodiment Construction

[0019] In the embodiment of the present invention, each time the system starts an application program, the corresponding memory dynamic application information is established for the application program, and during the execution of any application program, the memory dynamic information corresponding to any application program is counted multiple times according to the preset method. Application information: analyze the changes of the dynamic memory application information according to the obtained statistical results, and determine that there is a memory leak in any application program when it is determined that the memory dynamic application information changes regularly. Combined with the statistics of key data in the memory application information, it is possible to easily determine whether there is a memory leak, accurately locate the location of the memory leak in the code, and facilitate system testers to debug the system for memory leaks.

Abstract

The invention discloses a memory leakage detecting method and a memory leakage detecting device. The method comprises the following steps of: after a system starts one application program each time, establishing corresponding memory dynamic applying information aiming at the application program, and carrying out statistic on the memory dynamic applying information corresponding to any one application program for many times according to a preset way in the execution process of the any one application program; and analyzing the variation condition of the memory dynamic applying information according to each obtained statistic result, and judging that the memory leakage exists corresponding to the any one application program when the memory dynamic applying information is determined to generate regular variation. In such way, the memory leakage can be conveniently judged whether to exist or not; the position of the memory leakage in a code is accurately positioned; and a system tester can conveniently debug the system aiming at a memory leakage problem.

Description

technical field [0001] The invention relates to the field of communication equipment testing, in particular to a memory leak detection method and device. Background technique [0002] When the program is running, the memory dynamic space application statement in the program will apply to the system for space for storing data. At this time, the system will open up a dynamic space from the heap space of the memory and allocate it to the application program; when the program finishes running , the system releases the dynamic space opened up for the program so that other programs can continue to use the heap space when running; at this time, there may be a situation where the system fails to release the temporarily opened dynamic space in time due to a program design error. This situation is memory leak. [0003] Memory leaks will make the system heap space smaller and smaller, and the system running speed will slow down. When the memory leak reaches a certain level, the syste...
