TCP connection termination
To establish a connection over TCP, three sub-sections are required. To terminate a connection, four sub-sections are required.
(1) An application process first calls close. We call this end to take the initiative to close it. The TCP End sends a fin Shard, indicating that the data has been sent.
(2) The Peer of the received fin is

This article refer to "http://ifeve.com/java-two-phase-termination/"two-phase Termination Mode introductionStopping a thread is a simple, but not simple, task for a goal. First, Java does not provide a direct API for stopping threads. In addition, the stop thread has some additional details to consider, such as a stopped thread that is blocking (such as waiting for a lock) or waiting (waiting for another th
Some functions related to normal or abnormal program termination are provided in the C standard library , which is described below.Reference documents:[1] C and pointers, p298,342[2] C modern method of programming language (2nd edition), P489[3] Understanding of the Atexit function and the Exit function1 abort ()The abort () function is used to terminate an executing program abnormally. The function prototypes are as follows:void abort (void)This fun
process termination can be divided into normal process termination and process exception termination.
The normal termination of a process is as follows:
The main function returns
Call the Exit function
Call the _exit or _exit function
The last thread returns from the startup code
libing.(iv) Termination of the processSince a program starts again, there must be a termination. There are 8 ways to terminate a process, 5 of which are normal termination: returning from Main, calling Exit, calling _exit or _exit, the last thread returning from its startup routine, and the last thread invoking the Pthread_exit;3 type of exception
Regarding the establishment and termination of a TCP connection, the tcp connection is terminated.
0. Preface
Recently, when dealing with the company's legacy projects, I found that I didn't understand the TCP protocol at all, so I made up some content about the establishment and termination of the TCP connection. Here I will briefly write down what I know, the irrelevant fields of the message serial number
SYN to the customer and an ACK to the Customer SYN in a single subsection. 4. The customer must confirm the Syn of the server. The connection establishment process requires at least three packets to be exchanged, so it is called a three-way handshake by TCP (Three-way handshake) Termination of TCP connection:TCP uses three sub-sections to establish a connection, and terminating a connection requires four sub-sections.1. An application process
In general, there are two scenarios for POSIX thread termination: normal termination and abnormal termination. A thread's active invocation of pthread_exit () or return from a thread function causes the thread to exit normally, which is a predictable exit method, which is unpredictable if the thread exits with the intervention of another thread, or because of an
Reprint Please specify source: Jiq's technical BlogAfter my tests, I came to the following conclusions about session termination:The client creates a zookeeper instance to connect to the zookeeper server and sets the session timeout to 10s.(1) If the zookeeper server is forced to shut down (simulating its crash), the client immediately receives the disconnected connection disconnect event, waits half an hour, starts the zookeeper server again, the client receives the Syncconnected connection est
1.1.unexpected termination of thread in thread poolIf a thread in the thread pool has an exception to the task code that causes the thread to terminate, a new thread is automatically created by the thread pooling.This is true for various types of thread pools. The following code throws an exception in the thread pool of a single thread, and you can see that the values for each tid that are output in subsequent tasks are not the same. Executorservice E
1. Exit FunctionThe C,c++ function exit is used to terminate the current program, and the function is defined as follows:
void exit (int status);
The official notes are as follows:Terminates the process normally, performing the regular cleanup for terminating programs.Normal program termination performs the following (in the same order):

This is because. NET Framework 1.0 and 1.1 provide support for many unprocessed exceptions (for example, unprocessed exceptions in thread pool threads), while in Framework 2.0, the Common Language Runtime Library allows the majority of threads to continue without handling exceptions. In most cases, this means that unhandled exceptions will cause application
Process Termination:
There are eight methods to terminate the process, of which five are normal termination.
(1) return from main
(2) Call exit
(3) Call _ exit or _ exit
(4) The last current response from the startup routine
(5) The last thread calls pthread_exit.
There are three methods to terminate an exception:
(6) call abort
(7) receive a signal and terminate
