Thread lock management system, method and equipment and readable medium

Abstract

The invention relates to the field of resource scheduling, in particular to a thread lock management system, method and equipment and a readable medium. A thread lock management system includes: a management pool having a first container and a second container; the first container is used for storing a thread lock in use and storing a corresponding relationship between a code and the thread lock; the second container is used for storing a plurality of blank thread locks; and the processing unit calls a corresponding thread lock if the first code exists in the first container. When a system needs to call a certain thread lock, preferentially querying whether the thread lock corresponding to the first code is used in the first container, if so, directly calling, if not, taking a blank thread lock from the second container for calling, and after the calling succeeds, taking the thread lock corresponding to the first code from the second container for calling; if yes, the first code and the thread lock are matched and stored in the first container, subsequent calling is facilitated, the reusability of the thread lock is improved, and the thread lock is prevented from being repeatedly reconstructed and destroyed.

Description

technical field [0001] The present invention relates to the field of resource scheduling, and in particular, to a thread lock management system, method, device and readable medium. Background technique [0002] For code segment or resource access, thread locks are mostly used to avoid simultaneous access. When the program is very large or the number of objects is large, thread locks will be used in quite a few places. Frequent creation and destruction of locks will bring performance loss, especially Yes, if each object has a built-in lock, there will be a higher memory footprint. [0003] The patent document with the application number of 202011039645.8 discloses a method and an apparatus for protecting resources through an object lock. A specific implementation of the method includes: in response to receiving an access request to the target resource, associating a new object lock for the value of the target resource, and initializing attribute information of the new object...

AI Technical Summary

Problems solved by technology

However, during the application of this method, even in the same code segment, the lock must be acquired every time it is used, which may take extra time

And in order to prevent resources from being accessed at the same time, only one thread owns the lock, so when the thread acquires the lock, it has to wait for the previous thread to release the lock. If you want to access the resource multiple times, you need to repeatedly acquire and release the lock, which may involve frequent creation and destruction of object locks
