Dubbo 2.0.10发布记录：
http://code.alibabatech.com/wiki/display/dubbo/Release+Notes#ReleaseNotes-2.0.10%2820111228%29

BUG修复：

[DUBBO-70] - 修复Cluster层传递RpcException的ErrorCode
[DUBBO-101] - 增加init属性确定是否在afterpropertiesSet时饥饿初始化
[DUBBO-124] - telnet 向上键失效
[DUBBO-131] - telnet 缓存问题，历史记录没有设置上限。
[DUBBO-132] - bytecode包的Wrapper的反射方法调用，提供方没有重载的方法时，当提供多余的参数时，多余参数会被忽略（应该报错）
[DUBBO-141] - 共享连接后，不能使用连接上保存的服务信息，否则多服务时会有问题
[DUBBO-142] - DubboCodec在获取函数时没有判断$invoke和$echo等特殊函数
[DUBBO-144] - 扩展点加载失败（如依赖的三方库运行时没有），如扩展点没有用到，则加载不要报错（在使用到时报错）
[DUBBO-146] - 调用的返回值在Provider端序列化失败（如传输对象没有实现Serialiable接口），Provider端也没有异常输出，Consumer端超时出错
[DUBBO-148] - telnet请求没有终结，死循环发送消息
[DUBBO-152] - RegistryDirectory在unsubscribe之后再标记为destroyed，否则unsubscribe会失败
[DUBBO-155] - zookeeper注册的时候抛ConnectionLoss异常
[DUBBO-157] - 配置加载时对${user.home}等占位符没有替换
[DUBBO-158] - Config类的toString方法显示的标签名不对

功能改进：

[DUBBO-113] - registry客户端缓存采用ip作为key
[DUBBO-145] - 服务方法调用重试过程中输出引起重试异常的日志
[DUBBO-147] - 通过RpcContext可以获得所有尝试过的Invoker
[DUBBO-149] - <dubbo:protocol>未配name时，生成的缺省id也应为dubbo，便于-D参数覆盖
[DUBBO-153] - telnet增加--no-prompt参数，用于nc获取信息时不显示提示符
[DUBBO-159] - URL基于host自动添加anyhost和localhost参数
[DUBBO-160] - 给Multicast和Zookeeper注册中心URL增加缺省端口

这是什么情况？貌似网络不通了，过一分钟又联上了。

你的机器的缺省网关没配置。

缺省网关肯定有，否则机器就上不了网

慢的问题，我们再Profiler分析一下，看能不能优化，有结果再答复你。
ok   哥们等着你好消息


在2.1.0实现了Redis注册中心，如果嫌Zookeeper慢，可以考虑试用Redis注册中心，使用手册：RedisRegistryReference，安装手册：
RedisRegistryInstallation，试用下载：Download

同时开多个服务连接注册中心，在ReferenceConfig.get()的时候非常慢，大概持续30秒左右，这是抛出来的异常，麻烦帮我看看是什么问题


... Failed to uregister ...

上面的异常只是Dubbo的ShutdownHook在执行uregister失败，只是停止时报错，不影响运行，可能是停止顺序问题，建议使用2.0.13版本。

启动dubbo-demo-provider-2.0.12的时候抛的异常

请暂不要使用simple-registry，已知有问题，还来不及改。

dubbo如何实现多IDC的服务分布？ 针对国内南北延时大、速度慢的问题dubbo是否有相关优化？

对于多IDC没有做特殊优化，我们是每个IDC部署一个注册中心，因为有专线，跨IDC调用延迟也能忍受，比如青岛调杭州延迟15ms左右。


专线是向电信公司申请的还是公司自己布的？

container为服务容器， 是不是用来启动dubbo服务的？ container中启动与应用服务器中启动有什么区别？ 生产环境中建议container启动吗？

因为Dubbo的服务提供者通常是一个后台Daemon程序，不需Tomcat等Web容器，直接用Main加载Spring占用资源更少，Container就是一个这样的Main，在阿里内部也有很多项目使用该Main启动，生产环境建议用Container启动。

rmi协议下会同时调用multicast广播端相同所有服务，如果关掉其中一个服务，就会抛异常


嗯，RMI协议的Graceful Shutdown处理没有Dubbo协议严格，所以在尝试到不可用机器时会有WARN信息，但因为有重试，所以会调用成功。

而且Multicast注册中心，如果提供者意外退出，消费者是收不到消息的，就不会主动删除提供者，换成Zookeeper注册中心就不会有此问题，Zookeeper服务器会推送临时数据断线删除事件。
