The idle thread is a special thread in the system thread that has the lowest priority, and when no other threads in the system can run, the scheduler dispatches to the idle thread. Idle threads are usually a dead loop and are never suspended. The Rt-thread real-time operating system provides a hook function for idle th

About the Idle processthat is the process of pid=0. It is the first process created after the kernel has completed initialization and executes when the system is idle. Its code is simple:for (;;) pause ();Emphasize that the idle process is a user-state process. So the problem is that the kernel is always in the kernel state from boot to initialization, so how doe

All databases are automatically cleared of idle connections that are timed out, because the database itself is a socket server, and it must periodically clear dead connections to keep them running for long periods of time.After the database clears the idle connection, the con.connected inside the middleware connection pool is still equal to true, that is, in the middleware is unable to determine whether the

Most technical experts know this fact, but we haven't discussed it in detail about how the CPU switches from idle to working and then back to idle. This mechanism becomes increasingly important for modern processors; One of the goals of today's chip design is

You may have heard of many troubleshooting methods for vswitches by Using idle ports of vswitches. The following describes how to use idle ports of vswitches to analyze network traffic, how can we use this method to make it easier for us? The following describes how to troubleshoot a vswitch. In a switched network, it is often more difficult to troubleshoot a vswitch than to troubleshoot a vro. Although the

For the server version SDK, I will describe its queue management details here, but you do not need to know these things when using the SDK alone,

It is used to determine whether the system is idle during code compilation. It must be used in both Linux and Windows. Initially, the getsystemtimes function was used for determination. Later, it was found that it could not be used in Win2000. Later, we switched to the performance API, which provides four interfaces: WMI, ODBC, registery, and PDH. Registry seems to be the best choice, but in fact there are too few materials available and it is useless

Most people usually execute the reload (SYS) statement just to be able to modify the Python default character set, which is the ability to call sys.setdefaultencoding (). However, if you execute reload (SYS)in idle, you will cause the next failure to execute any commands.At first there was nothing to do with the problem, and later on StackOverflow it was seen that someone had said it. This is because idle,

Idle is a python Development Environment officially recommended by python. It is very convenient. It supports syntax highlighting and Automatic completion, and supports one-click operation. Take two screenshots to see the effect. The first one is the Editor interface and the second is the running environment interface. I have tried several other models and found that they are not easy to use. The official Python installation package i
