昨天分析完adlist的Redis代码.今天立即马不停蹄的继续学习Redis代码中的哈希部分的结构学习,只是在这里他不叫什么hashMap,而是叫dict.并且是一种全新设计的一种哈希结构,他仅仅是通过几个简单的结构体.再搭配上一些比較常见的哈希算法,就实现了类似高级语言中HashMap的作用了.也让我见识了一些哈希算法的实现.比方dbj hash的算法实现.俗称times33,算法,就是不停的*33,.这样的算是一种超级简单的哈希算法. 以下说说给我感觉Redis代码中哈希实现的不是那么简单.…

snull是<Linux Device Drivers>中的一个网络驱动的例子.这里引用这个例子学习Linux网络驱动. 因为snull的源码,网上已经更新到适合最新内核,而我自己用的还是2.6.22.6比较旧的内核.而网上好像找不到旧版的snull.因此结合<Linux Device Drivers>把最新的snull例子移植到2.6.22.6内核中.移植也相对简单,这里也提供移植好的代码. 估计不少网友看到<Linux Device Drivers>的网络驱动部分,…
