小编kif*_*ord的帖子

在TortoiseMerge文档中,等号表示:

通过恢复到该行的原始内容,撤消了更改.

小组显示了矿山或他们的基地之间的差异,我的问题是:

如果删除某些内容,则可以使用减号.如果添加了某些内容,则可以使用添加符号.为什么需要等号？描述"线条的原始内容"是什么意思？

我有一个安装了Docker的CentOS 7.2 VM.Docker服务和Docker容器以前正常工作.但是当我试图拉出一个docker镜像时,VM突然关闭了.重新启动VM后,无法启动Docker服务:

[root@AY13091717064020986bZ ~]# service docker start
Redirecting to /bin/systemctl start  docker.service
Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

systemctl status docker.service 输出:

[root@AY13091717064020986bZ ~]# systemctl status docker.service

我将我的grunt项目迁移到ember-cli,我发现从文件修改到liveload完成的时间很长,大约10分钟.

在我安装了ember-cli-windows,ember-cli-windows-addon之后,没有获得明显的提示.以下是安装ember-cli-windows,ember-cli-windows-addon之后的一个示例输出:

相比之下,在文件修改后的grunt项目中,构建过程可以在2~3秒内完成.

我用的是Windows 7.

我使用带有websocket支持的spring 4.0.3,我的websocket的spring配置是:

<websocket:message-broker application-destination-prefix="/kiford">
    <websocket:stomp-endpoint path="/websocket">
        <websocket:sockjs/>
    </websocket:stomp-endpoint>
    <websocket:simple-broker prefix="/queue, /topic"/>
</websocket:message-broker>    

当我的客户端连接到服务器时:

        this.socket = new SockJS('websocket/'); 
        this.client = Stomp.over(this.socket);
        this.client.connect({}, success_callback, error_callback);

spring的控制台打印了以下错误消息:
