Method for rapidly positioning memory leak

Abstract

The invention discloses a method for rapidly positioning memory leak. The method includes steps of S1 applying for an extension area with a predetermined size in a memory when the memory is applied for, wherein the extension area is used for saving memory header information; S2, initializing the header information into a first identifier and saving function information calling the application memory; S3, adding the memory to a memory chain table; S4, arranging the header identifier information as a third identifier when the applied memory is released and saving function information for calling the released memory; S5, deleting the released memory from the memory chain table; S6, traversing the memory chain table when the memory leak needs positioning, and counting times of memory application of the same functions according to the function information, wherein the function with the continuously increased times for memory application is a function with memory leak. By means of the method for rapidly positioning the memory leak, specific functions and code lines with memory leak can be clearly displayed from more to less or from less to more according to memory application times of the functions, and rapid positioning is achieved.

Description

technical field [0001] The invention relates to the field of memory management, in particular to a method for quickly locating memory leaks. Background technique [0002] In today's IT industry, one of the most frequent operations in code development is the application and release of memory. If the memory is not released in time after the application, and this happens frequently, the remaining memory will continue to decrease, and the available memory will gradually decrease. This situation is usually called a memory leak. If there is a memory leak, the developer needs to spend more time looking at the code and finding the place that has not been released. Therefore, the memory leak problem has always been a major problem that plagues the developer's positioning problem, and often requires the developer to spend a lot of time to find out. Where there is a memory leak, it is time-consuming and labor-intensive. An existing method for locating memory leaks is as follows: firs...

If there is a memory leak, the developer needs to spend more time looking at the code and finding the place that has not been released. Therefore, the memory leak problem has always been a major problem that plagues the developer's positioning problem, and often requires the developer to spend a lot of time to find out. Where memory leaks, time-consuming and labor-intensive

Technical problems of this technology: need to start a new program, which has an impact on the operating environment of the existing program, which may cause unknown problems, and also needs to replace the memory allocation interface, create a trace file, and confirm whether it is based on the trace file There is a memory leak. If there are many places to apply for memory, the amount of information in the tracking file is very large, and it is not easy to locate
