Java多线程之多线程的锁机制
当两条线程同时访问一个类的时候，可能会带来一些问题。并发线程重入可能会带来内存泄漏、程序不可控等等。不管是线程间的通讯还是线程共享数据都需要使用Java的锁机制控制并发代码产生的问题。本篇总结主要著名Java的锁机制，阐述多线程下如何使用锁机制进行并发线程沟通。1、并发下的程序异常 先看下下面两个代码，查看异常内容。 异常1：单例模式 1 package com.scl.thread; 2 3...

消息队列的简单实现
消息队列：一个进程向另一个进程发送数据块 消息队列基于消息，管道基于字节流 消息队列是用链表实现 1.创建：int megget(key_t key, int msgflag) key:函数ftok()的返回值 msgflag:IPC_CREAT是创建新的消息队列；IPC_EXCL与IPC_CREAT一起使用，即如果要创建的消息队列已存在，则返回错误 成功：返回队列标识符 失败：-1...

进程间通信之信号量
本质：计数器。当前资源个数 生命周期：随内核 本身不具有数据交换的功能，是通过控制其他通信资源（文件、外部设备）来实现进程间通信，本身是一种外部资源的标识。在此过程中负责数据操作的互斥与同步功能。 互斥：独占临界资源（排他） 同步：建立在互斥基础上（顺序性） 主要作用：协调进程对共享资源的访问，保证在任一时刻，只有一个执行线程访问代码的临界区域。（其中共享内存的使用就要用到信号量） 操作：...

View Article关于保留最新文件或清除过期文件的简单总结
在运维工作中经常遇到要管理备份、日志等与时间戳有关的文件，例如删除超过10天的备份/日志文件，保存最新的10个的备份/日志文件等。 “删除超过10天的备份/日志文件”是用的比较多的一种，通常用于定时计划任务，每次产生这些文件都是规律的时间点。 “保存最新的10个备份/日志文件”这种需求通常用在不定时的产生备份（例如每次手动执行一次产生）和日志文件（超过一定的大小则切割）。...
