/* thread-unsafe function */ int increment_counter() { static int counter = 0; counter++; return counter; } 为使该函数线程安全,静态变量counter 需要被静态锁保护,如下例(伪代码)所示: /* pseudo-code threadsafe function */ int increment_counter(); { static int counter = 0; static lock_type...

也就是说明中的function uses a global variable that is not protected
Revert "n-api: detect deadlocks in thread-safe function"… 9eec1ed This reverts commitd26ca06because it breaks running the tests in debug mode, as `v8::Isolate::GetCurrent()` is not allowed if no `Isolate` is active on the current thread. Refs:Refs: ...
I was under the impression that all re-entrant are thread-safe.Is this assumption wrong? 但想想我好像也分不太清这俩啥区别,对可重入(reentrant)的认识主要还是关于内核中断处理时重新使能中断带来的一些问题。因此闪过的第一个念头是: 可重入是线程安全的充分条件?毕竟都可以重复进入执行了,应该也就线程安全...
析构阶段的thread-safe的难点的根本在于:因为一个对象的mutex的生命周期最多等于该对象的生命周期,而析构阶段在对象的生命期之后!因此指望单个mutex能够做到完美的保护是不现实的。mutex只能保证类中的其他函数单个单个地执行。 3. 函数内部Lock多个对象 这种情况会有潜在的死锁可能。解决方案之一是:按照对象的地址顺序...

"Thread safe" is a bit of a C throw-back, where you can determine if a particular function is thread safe if it isn't dependent on any stored state. However an object could only be deemed thread safe in the same manner if it didn't maintain any state, which wouldn't be much of...
If we need to share state between different threads, we can create thread-safe classes by making them immutable. 如果我们需要在不同线程之间共享状态,则可以通过使它们的值不可变来创建线程安全类。 Immutability is a powerful, language-agnostic concept and it's fairly easy to achieve in Java. ...
