Multi-thread log output method and device

Abstract

The invention discloses a multi-thread log output method. The method comprises the steps that a log sequence number counting program is called to set log sequence numbers for all logs according to thesequential order of log generation time of all service threads; all the logs are cached into log cache regions corresponding to the service threads; when a log output command input by a user is received, a log output thread is utilized to traverse all the log cache regions to find logs corresponding to the log output command; and the logs corresponding to the log output command are output according to the order of the log sequence numbers. According to the method, by presetting the log cache regions, isolation of output logs is realized; by calling the log sequence number counting program toset the log sequence numbers for all the logs, it is convenient to review the calling order of all the service threads; and by utilizing the log output thread to perform asynchronous order-placing output on the logs, the influence of log output on a system is lowered to the minimum. The invention meanwhile provides a multi-thread log output device, equipment and a computer readable storage medium.The multi-thread log output device, the equipment and the computer readable storage medium also have the advantages.

Description

technical field [0001] The present application relates to the field of software development, and in particular to a method, device, device and computer-readable storage medium for outputting multithreaded logs. Background technique [0002] In software development, it is a common method for developers to realize multi-threaded concurrent operation, and the log system is a necessary means to detect the running status of the software. The main design idea of ​​the multi-threaded daily arrival system is that through a shared queue, multiple input terminals can simultaneously add record information to the queue in a non-blocking manner, and the output terminal can automatically and timely output the record information in the queue to the console or It is stored in files and databases. In order to ensure the consistency of multi-threaded output logs, a common method is to lock and protect the modification of the shared queue to prevent multiple threads from modifying the queue a...

AI Technical Summary

Problems solved by technology

[0003] However, this method of locking protection has disadvantages: it is impossible to display the calling sequence of each thread, which makes it difficult for developers to detect the running status of each thread in the software

At the same time, the competition of mutexes will lead to the reduction of system performance.
