Embodiment Construction

[0071] In the embodiment of the present invention, by collecting at least one program running resource usage in each program running resource usage cycle, for any two program running resource usage cycles, determine the program running resource usage collected each time in the latter cycle, and According to the difference between the total amount of program running resource usage collected in the previous cycle, whether there is a program running resource leak is determined based on the difference between the total number of differences greater than 0 and the total number of differences less than 0 among the determined differences. The embodiment of the present invention can realize the analysis of the program operation resource usage of different program operation resource usage periods in the program operation process, so that the program operation resource usage in different stages of the program operation can be obtained, and it can be more accurately judged whether there is...

Abstract

A method and device for determining resources leakage during program execution, relating to the field of computer application, used to solve the problem of erroneous reports, missing reports, and lack of universality in existing methods for detecting resource leakage during program execution. The present invention also relates to a method and device for predicting the resource usage state during program execution, and is used to solve the problem of the lack of capability to predict future resource usage state during program execution. The method for predicting resource usage state during program execution comprises: collecting at least once the resource usage during program execution in each resource usage cycle during program execution; dividing the collected resource usage during program execution into different resource components; for data included in each resource component, determining the prediction function for the resource component; determining the comprehensive program execution resource prediction function according to the determined prediction function for each resource component; predicting the resource usage state during program execution according to the determined comprehensive prediction function.

Description

technical field [0001] The present invention relates to the field of computer applications, in particular to a method and device for judging the leakage of program running resources, and a method and device for predicting the use of program running resources. Background technique [0002] Program running resources, such as memory, file handles, semaphores, database connection pools, thread pools, etc., are the key resources needed when the program is running. During the running process, the program makes an application when it needs to use program running resources, and releases the occupied program running resources in time after use; if the occupied program running resources are not released in time, the problem of program running resource leakage will occur. The following uses a memory leak as an example to describe the problem of program running resource leaks in detail. [0003] A memory leak means that due to design or coding problems, the program does not release the...
