什么是Check Check是C语言的一个单元测试框架。它提供一个小巧的单元测试接口。测试案例运行在各自独立的地址空间,所以断言失败和代码错误造成的段错误或者其他的信号可以被捕捉到。另外,测试的结果显示也兼容以下这些格式:Subunit、TAP、XML和通用的日志格式。 Check is a unit testing framework for C. It features a simple interface for defining unit tests, putting little in the way of the developer. Tests are run in a separate address space 继续阅读 »

Why 读ConcurrentHashMap的时候,我们遇到的一个很大的概念就是Segment(java8之后只有在调用writeObject方法的方法的时候才会用到segment),该类继承了ReentrantLock,用于实现分段锁(乐观锁)。处于心痒痒的目的,我也尝试写了个简陋版的分段锁。 How 该Demo实现的比较简单:根据key获取或者创建Lock(获取锁的时候使用double check),然后使用该锁来同步put或者read(ConcurrentHashMap的读操作使用的volatile,这里不深入)。不足之处还请指正~ What java实现: github more ```java package 继续阅读 »
