preface This article is my learning record of learning Python 3 multithreading for the first time. I have a relatively shallow understanding soon after I start learning. I hope you guys will forgive me. 1, Introduction to multithreading I've been exposed to multithreading since Python 3, and I haven't been exposed to multithreading ...

Catalogue of series articles preface 1, Linux thread concept 1. What is a thread An execution route in a program is called a thread. A more accurate definition is that a thread is "the internal control sequence of a process".All processes have at least one execution thread.Threads run inside a process, essentially in ...

wait/notify mechanism principle Only threads with the same lock can implement the wait/notify mechanism The wait method is a method of the Object class. Its function is to make the thread currently executing the wait method wait, pause the execution at the code where the wait is located, and release the lock until it is notified or interr ...

What is synergetic process In short, a coroutine is an existence based on threads, but more lightweight than threads. For the system kernel, the co process has invisible characteristics. Therefore, this lightweight thread managed by programmers writing their own programs is called "user space thread". Advantages of more threads 1. ...

1, What is JMM 1. Concept JMM:Java virtual machine is a cross platform virtual system, so it also has its own memory model, namely Java Memory Model (JMM). 2. JMM synchronization Before the thread is unlocked, the shared variable must be flushed back to main memory immediately. Before locking a thread, you must read the latest value in ma ...

java provides three CAS operations in Unsafe: compareAndSwapInt()，compareAndSwapObject()，compareAndSwapLong() //Parameter meaning: object, attribute memory offset, attribute expected value, attribute update value public final native boolean compareAndSwapObject(Object var1, long var2, Object var4, Object var5); public final native boolean ...

1. Write in front I've been studying the code of our products recently, In some functions Asynchrony has been used in (for example, warehousing), but it has not been studied in detail for so long. Many popular explanations of relevant contents on the Internet are based on life examples such as making tea and washing clothes. Personally, I thin ...

Blocking queue, as the name suggests, is a queue first, and the role of blocking queue in data structure is: Thread 1 adds elements to the queue, and thread 2 takes elements from the queue. When the blocking queue is empty, the operation of fetching elements from the queue will be blocked. When the blocking queue is full, adding elements to th ...

In daily development, it is often encountered that the foreground calls the service, then triggers a time-consuming asynchronous service, and returns the original service without waiting for the processing result of the asynchronous task. Here is a knowledge of Java asynchronous call. The following article attempts to summarize the var ...
