1、若事务控制器下有多个请求,勾选后在“查看结果树”中可同时看到事务控制器和每个取样器(请求);2、是否控制器的成功取决于子事务是否成功;3、任何一个失败代表整个事务失败 |
Include duration of timer and pre-post processors in generated sample |
是否包括定时器、预处理和后期处理延迟的时间 |

我发现ActiveRecord::Base.transaction在复杂方法中非常有效。我想知道是否可以在如下事务中从AWSS3上传/删除文件:S3Object.transactiondo#writeintofiles#raiseanexceptionend引发异常后,每个操作都应在S3上回滚。S3Object这可能吗?? 最佳答案 虽然S3API具有批量删除功能,但它不支持事务,因为每个删除操作都可以独立于其他操作成功/失败。该API不提供任何批量上传功能(通过PUT或POST),因此每个上传操作都是通过一个独立的API调用完成的
我有一个涉及多台机器、消息队列和事务的问题。因此,例如用户点击网页,点击将消息发送到另一台机器,该机器将付款添加到用户的帐户。每秒可能有数千次点击。事务的所有方面都应该是容错的。我以前从未遇到过这样的事情,但一些阅读表明这是一个众所周知的问题。所以我的问题。我假设安全的方法是使用两阶段提交,但协议(protocol)是阻塞的,所以我不会获得所需的性能,我是否正确?我通常写Ruby,但似乎Redis之类的数据库和Rescue、RabbitMQ等消息队列系统对我的帮助不大——即使我实现某种两阶段提交,如果Redis崩溃,数据也会丢失,因为它本质上只是内存。所有这些让我开始关注erlang和

我已经开始使用mysql2gem。我试图弄清楚一些基本的事情——其中之一是如何明确地执行事务(对于批处理操作,比如多个INSERT/UPDATE查询)。在旧的ruby-mysql中,这是我的方法:client=Mysql.real_connect(...)inserts=["INSERTINTO...","UPDATE..WHEREid=..",#etc]client.autocommit(false)inserts.eachdo|ins|beginclient.query(ins)rescue#handleerrorsorabortentirelyendendclient.commi

TCL脚本语言简介•TCL(ToolCommandLanguage)是一种解释执行的脚本语言(ScriptingLanguage),它提供了通用的编程能力:支持变量、过程和控制结构;同时TCL还拥有一个功能强大的固有的核心命令集。TCL经常被用于快速原型开发,脚本编程,GUI和测试等方面。•实际上包含了两个部分:一个语言和一个库。首先,Tcl是一种简单的脚本语言,主要使用于发布命令给一些互交程序如文本编辑器、调试器和shell。由于TCL的解释器是用C\C++语言的过程库实现的,因此在某种意义上我们又可以把TCL看作C库,这个库中有丰富的用于扩展TCL命令的C\C++过程和函数,所以,Tcl是
