让我们看看下面这段代码在Java中 int x = 0;
int who = 1
Thread #1:
(1) x++;
(2) who = 2;
Thread #2
while(who == 1);
x++;
print x; (the value should be equal to 2 but, perhaps, it is not*
的我的问题是给帖子： https://shipilev.net/blog/2014/safe-public-construction/ public class UnsafeDCLFactory {
private Singleton instance;
public Singleton get() {
if (instance == null) { // read
所以我有一个简单的cow_ptr。它看起来是这样的： template<class T, class Base=std::shared_ptr<T const>>
struct cow_ptr:private Base{
using Base::operator*;
using Base::operator->;
using Base::operator bool;
假设我想使用布尔状态标志在线程之间进行协作取消。 （我认识到，一个最好使用CancellationTokenSource代替，这些都不是这个问题的地步。） private volatile bool _stopping;
public void Start()
{
var thread = new Thread(() =>
{
while (!_stoppin
Joe Albahari在C＃中解释了volatile的一篇很好的文章：Threading in C#: PART 4: ADVANCED THREADING。 考虑指令重新排序乔使用这个例子： public class IfYouThinkYouUnderstandVolatile
{
private volatile int x, y;
private void Tes
在一篇文章中有关A scalable reader/writer scheme with optimistic retry有一个代码示例： using System;
using System.Threading;
public class OptimisticSynchronizer
{
private volatile int m_version1;
private
我书面方式这篇文章中的连接上下文的JIT产生的x86输出到Deep understanding of volatile in Java public class Main {
private int x;
private volatile int g;
public void actor1(){
x = 1;
g = 1;
}
