Problems solved by technology

due to figure 1 In the reference ring shown, each object refers to each other, therefore, the reference count value of each object in the reference ring is at least 1, and cannot become 0, resulting in the memory occupied by each object in the reference ring None of the resources can be recycled, resulting in a waste of memory resources

Abstract

The invention discloses a memory management method and a memory management device, which are used for recovering memory occupied by an object in a reference ring. When the method is used for garbage collection, firstly, stored information of a first reference ring is obtained, the first reference ring is a circular reference formed by multiple objects, and the information of the first reference ring comprises the multiple objects in the first reference ring and reference relations among the multiple objects; secondly, it is determined that a second reference ring exists, information of the second reference ring is matched with information of the first reference ring, and the information of the second reference ring comprises multiple objects in the second reference ring and reference relations among the multiple objects; and then recovering the memory occupied by the plurality of objects in the second reference ring. Through a mode of matching the information of the reference ring, therecovery process of the reference ring is realized, and the problem of memory resource waste caused by incapability of recovering the reference ring can be avoided.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a memory management method and device. Background technique [0002] Garbage collection is a mechanism in computer technology for automatic management of computer memory. Its main idea is: when an application program is running on the computer, there will be an object in the application program that references another object (this object also may be referred to as in-memory objects or nodes), and each object takes up memory on the computer. If an object is no longer needed, that is to say, the object is not referenced by any other object, the object should be released so that the memory occupied by the object can be used by other objects to achieve the effect of automatically reclaiming memory resources . [0003] Currently, a commonly used technical solution for implementing garbage collection is a reference counting (reference counting, RC) algorithm. The RC algo...
