A resource leak detection method, device and system

Abstract

The embodiment of the present invention discloses a resource leakage detection method, device and system, the method comprising: obtaining the target resource called by the target code of the program when running; wherein the target code is part of the program code; determining the target resource the first amount of storage resources occupied; judging whether the first amount of storage resources occupied by the target resource satisfies the first preset condition; if the first amount of storage resources occupied by the target resource satisfies the first preset condition, the The storage location was determined to be the location of the resource leak. In the embodiment of the present invention, the object code of the program can be tracked, and the storage location of the object code can be further detected and determined as the resource leak location, without tracking all resource allocation and release, thereby reducing performance overhead and improving resource leakage. detection efficiency.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a resource leakage detection method, device and system. Background technique [0002] During the running of the program, some resources are usually called, such as memory, file handle, semaphore, message packet, database connection pool, etc., and the called resource needs to be released in time after the program finishes running. Resource leakage means that the program cannot release resources that are no longer used due to problems such as leaking release or stepping on memory, so that these resources cannot be reused. As resources continue to leak, the available resources of the system become less and less, resulting in system performance degradation, and eventually the system cannot provide services and process business due to insufficient resources. [0003] In a prior art, when memory is allocated, the number of times of memory allocation and the size of memory allocation ...

AI Technical Summary

Problems solved by technology

In this prior art, it is necessary to track and record all memory allocation and memory release, the detection overhead is high and the efficiency is low, it can only be used in the testing phase or debugging phase of the program, and the memory leak detection cannot be performed in the online environment where the program is actually running. It is impossible to detect memory leaks that are hidden and occur when the program is actually running. Undetected memory leaks will cause business damage or even business interruption
