Multi-thread scheduling method and device based on thread pool

Abstract

The embodiment of the invention discloses a multi-thread scheduling method based on a thread pool. The method comprises the steps that a calling process of a thread scheduling function of the thread pool is detected, and stack characteristic information of a calling stack corresponding to the calling process and a target task object are obtained; an operation function of the target task object is detected and called, a counting lock and / or a countdown lock corresponding to the stack characteristics information are / is added to the operation function of the target task object, the locking state of the counting lock and / or the countdown lock is detected, the counting lock is released when the thread number corresponding to the target task object is larger than or equal to the threshold value of the counting lock, and the countdown lock is released after a preset period of time is waited; when the counting lock and / or the countdown lock are / is in the locked state, the execution of the operation function of the target task object is stopped. When the locked state of the counting lock or the countdown lock is released, the operation function of the target task object is executed. By adopting the multi-thread scheduling method, the program crash recurrence rate can be increased.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a thread pool-based multi-thread scheduling method and device. Background technique [0002] With the development of communication and Internet technologies, various application programs are more and more widely used in users' lives, and users have higher and higher requirements on the performance of the application programs. Among them, stability is an important index to measure the performance of an application, and the stability of the application determines the retention rate and reputation of the application to a certain extent. Therefore, improving the stability of the application is very important for the application development is of great significance. During the development and use of the application, it will analyze and reproduce the program crash (Crash) that occurs during the running of the application, determine the specific cause of the trigger Crash, and make c...

Problems solved by technology

However, because many crashes on existing terminals are caused by multi-threaded competition for resources, in the Android system, in the process of scheduling and managing threads through the thread pool ThreadPoolExecutor, the start method is not called directly, but through The thread pool is used to determine the start time of each thread, that is to say, the start time of the thread is not determined by the developer, with uncertainty, for example, it will be affected by related factors such as the size of the thread pool, thread cache queue, etc. This leads to the fact that in the process of reproducing Crash, the developer cannot determine the specific start time of each thread, cannot reproduce the specific start time of each thread when the previously reported Crash occurred, and cannot restore it in program debugging or The specific usage scenario when the user uses it, and the real reason that triggers the Crash cannot be known

[0004] That is to say, in the above-mentioned related technologies, there is a problem that the Crash cannot be accurately located when the Crash occurs
