多线程应用程序的存在,在运行打开一个潜在的多线程安全的接入资源. 两个线程相同的资源可能会以意想不到的方式改变相互干扰. 例如.一个线程可以覆盖有一个线程改变或使应用程序进入一个潜在的无效的状态未知. 假设你幸运,毁坏的资源也能导致明显的性能问题或相对easy追踪和修复的崩溃.假设你不幸,然而.毁坏的资源可能导致微妙的错误,一直不显现直到非常久以后,或者错误可能须要对底层编码设计进行彻底检查. 当涉及到线程安全时,好的设计是最好的保护.避免资源共享和降低线程间的交互使它们不太相互干扰. 一个全然…

The HTML importer should not be called from a background thread (that is, the options dictionary includesNSDocumentTypeDocumentAttribute with a value of NSHTMLTextDocumentType). It will try to synchronize with the main thread, fail, and time out. Cal…

介绍:当开发一个多线程程序时,同步是一个很大的问题.如果你的程序需要数据流包,那么用队列是个好办法. 你可以在 http://www.boost.org/ 发现 boost 库和文档,从它的网站可以看出用boost的优势: In a word, Productivity. Use of high-quality libraries like Boost speeds initial development, results in fewer bugs, reduces reinvention-o…

前面的文章:多线程爬坑之路-学习多线程需要来了解哪些东西?(concurrent并发包的数据结构和线程池,Locks锁,Atomic原子类) 多线程爬坑之路-Thread和Runable源码解析 前面大致的了解了Thread的一些方法和属性下面对一些方法进行运用看看具体效果<下面可能还是会贴很多的源代码,其实我是拒绝的,我只想贴每个方法的代码,但是有时候看到一个方法里面有调用了方法,但是笔者有没有给出来,很蛋疼,有种爽到一半的感觉,所以我还是会把它贴出来,希望一次就能挖到底,不论有没有全懂,但至…

测试在进行一次性能测试的时候发现并发300个请求时出现了下面的异常: HTTP Status 500 - Handler processing failed; nested exception is java.lang.OutOfMemoryError: unable to create new native thread 看到这个异常有点发慌,毕竟并发程序写的少,突然来这么一个确实有点找不着背.但不管怎么样还是先搜索一下是啥原因吧. 这个错误是因为无法再创建新线程导致的,原因可能是没有更多的空…
