Timer task processing method and device and server

Abstract

The invention provides a timer task processing method and device and a server, which are applied to the technical field of computers, and the method comprises the following steps: after a task scheduler is locked, determining a current to-be-processed timer task in each timer task based on a preset circular linked list; and judging based on task information of the current to-be-processed timer task recorded in a preset circular linked list, and if the current to-be-processed timer task is not in a running state and the sleep duration of the current to-be-processed timer task is greater than or equal to a corresponding sleep duration threshold value, determining the current to-be-processed timer task as an executable task. And marking the executable task as a running state, and executing the executable task after the lock of the task scheduler is released. Compared with the prior art, undifferentiated execution frequency can be effectively avoided, so that waste of processor resources is avoided, and the execution efficiency of a real-time processing system is improved.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a timer task processing method, device and server. Background technique [0002] In practical applications, the application software in the real-time processing system often sets a large number of timer tasks that need to be executed according to a certain period, such as scanning the hash table. The effectiveness of the hash table and meet the real-time requirements of the real-time processing system. [0003] Different hash tables have different requirements for real-time performance. Some software business information is updated quickly, and the hash table is required to expire quickly after timeout, and the frequency of timeout scanning is high; some software business information is updated slowly. Correspondingly, the hash table The longer the timeout period, the lower the timeout scanning frequency. Most timer tasks in real-time processing systems have simil...

Problems solved by technology

[0004] In the prior art, the execution frequency of timer tasks is implemented based on hardware timers, that is, all timer tasks are processed at a fixed frequency. Taking scanning hash tables as an example, for hash tables with long timeouts, The frequency of overtime scanning to it will be far greater than the actual demand, and a large proportion of the scanning process does not need to be carried out. Therefore, the timer task processing method in the prior art will inevitably cause waste of processor resources, and even affect the entire real-time Processing System Execution Efficiency
