上一篇回顾:<memcached学习笔记——存储命令源码分析上篇>通过分析memcached的存储命令源码的过程,了解了memcached如何解析文本命令和mencached的内存管理机制. 本文是延续上一篇,继续分析存储命令的源码.接上一篇内存分配成功后,本文主要讲解:1.memcached存储方式:2.add和set命令的区别. memcached存储方式 哈希表(HashTable) 哈希表在实践中使用的非常广泛,例如编译器通常会维护的一个符号表来保存标记,很多高级语言中也显式的支持哈希…

原创文章,转载请标明,谢谢. 上一篇分析过memcached的连接模型,了解memcached是如何高效处理客户端连接,这一篇分析memcached源码中的process_update_command函数,探究memcached客户端的set命令,解读memcached是如何解析客户端文本命令,剖析memcached的内存管理,LRU算法是如何工作等等. 解析客户端文本命令 客户端向memcached server发出set操作,memcached server读取客户端的命令,客户端的连接状态…

[转][安卓笔记]AsyncTask源码剖析 http://blog.csdn.net/chdjj/article/details/39122547 前言: 初学AsyncTask时,就想研究下它的实现源码,怎奈源码看了好几遍都没看懂,于是搁置了.最近心血来潮,又看了一些源码,如 HandlerThread,IntentService,AsyncQueryHandler等,收获颇深,于是乎想回头再研究下AsyncTask, 没想到这次居然很容易看懂了... 正文: 注:1.读者阅读本文前,必须对…

一.前言 在分析了 AbstractQueuedSynchronier 源码后,接着分析ReentrantLock源码,其实在 AbstractQueuedSynchronizer 的分析中,已经提到过ReentrantLock,ReentrantLock表示下面具体分析ReentrantLock源码. 二.ReentrantLock数据结构 ReentrantLock的底层是借助AbstractQueuedSynchronizer实现,所以其数据结构依附于AbstractQueuedSynch…
