Thanks to CTOnews.com netizens for the clues of selling melons in the back row! CTOnews.com, May 5, according to the official website of the Chinese Academy of Sciences, the team of the Intelligent Software Research Center of the Software Research Institute of the Chinese Academy of Sciences has made progress in the research and development of key modules of the domestic open source operating system OpenHarmony. This research designed the log system model specification for the interconnection characteristics of OpenHarmony heterogeneous devices, and developed the first high-performance logging system HiLog for OpenHarmony. The related research results are entitled "Design and implementation of OpenHarmony High performance Log system HiLog" and are accepted by "Software Journal".

In the early days of the open source project, there are many key subsystems of the OpenHarmony operating system that have not yet been built, including the key log system. The log system is very important for the development and maintenance of the operating system. It records all the activities in the system, helps developers diagnose and solve faults, and ensures the security and stability of the system. In addition, the log system can help developers understand the usage of users and improve the function and performance of the system.

According to the Software Research Institute of the Chinese Academy of Sciences, "HiLog has become the core subsystem of OpenHarmony, with more than 450,000 lines of calls and 100% business coverage in its system source code." HiLog has been widely deployed and is used in 14 industry distributions and 32 commercial devices. With the release of HarmonyOS API-9, all HarmonyOS devices will use HiLog as the logging system. At that time, HiLog will run on more than 320 million devices, complete log collection and management, and provide important log data. "

Open source Hongmeng OpenHarmony is an open source project incubated and operated by the Open Atomic Open Source Foundation (OpenAtom Foundation). The goal is to build a framework and platform for intelligent terminal device operating systems based on open source, and to promote the development of the Internet of everything industry in the era of full scene, full connection and full intelligence.

The standard system of OpenHarmony 3.2 released in April this year is further improved (CTOnews.com Note: click this link to see more), supporting the use of ArkTS language for large-scale application, atomized service development. ArkCompiler optimization and Taskpool mechanism improve application performance; ArkUI components and animation capabilities are enhanced to enhance graphics rendering capabilities and system security capabilities to enrich distributed business development; OpenHarmony version 3.2 Release provides API Level 9 stable interface.
