ssh connecione Bugs

Could not establish connection. XHR failed

原因是没有网络，需要自己手动下载包

先查看包对应版本

# shaojiemike @ node5 in ~ [15:24:54] C:1
$ rm ~/.vscode-server -rf

# shaojiemike @ node5 in ~ [15:24:59]
$ ls ~/.vscode-server/bin/
784b0177c56c607789f9638da7b6bf3230d47a8c

下载对应版本，移动解压

set_proxy

wget https://update.code.visualstudio.com/commit:784b0177c56c607789f9638da7b6bf3230d47a8c/server-linux-x64/stable

mv stable ~/.vscode-server/bin/784b0177c56c607789f9638da7b6bf3230d47a8c/vscode-server-linux-x64.tar.gz

cd ~/.vscode-server/bin/784b0177c56c607789f9638da7b6bf3230d47a8c

tar -xvxf vscode-server-linux-x64.tar.gz --strip-components 1

重新连接即可

just remove the locked file

过程试图写入的管道不存在

Install terminal quit with output: 过程试图写入的管道不存在。

一般是本地的known_hosts冲突了，

删除对应项或者文件后。
terminal重新连接，添加known_hosts
VS Code 正常

服务器插件下载

设置代理，解决绝大部分问题

ssh 公钥的位置

cd
cat .ssh/id_rsa.pub

VSCODE C++ 自动跳转

已经安装了 C/C++和 C++ Intellisense 插件;
确认 C_Cpp: IntelliSenseEngine 的开关打开
1. 左击插件 C/C++，选择小齿轮 -> 扩展设置。
2. 搜索框内输入 “intell”，将 C_Cpp：Intelli Sense Engine 开关设置为 Default。
“Ctrl + Shift + P”打开C/C++:Edit Configurations(JSON)创建。

另一个基于ctag+vscode的实现方法

安装插件

VScode Debug Run

数组查看技巧

参考GDB的命令

多线程进程调试c++

-g -O0

修改代码

void LaunchProcess(uint32_t procIdx) {
    int cpid = fork();
    int tsj_flag = 1;
    while(tsj_flag){
        sleep(0.5);
    }

找到运行子进程的PID

VSCODE设置，连接上后需要暂停再启动一次

多线程进程调试python

图中白色是主进程，绿色是所属同名子进程，来负责不同的功能。

subprocess.Popen(cmd).communicate()time.sleep(20)launch.json

{
   "name": "Python: 使用 PID 连接",
   "type": "python",
   "request": "attach",
   "processId": "${command:pickProcess}"
  },

threading.Thread(target = fuc, args = (xxx)).start()

最终能有如下效果：

单线程启动

}

g++ -g -std=c++11 SLIC.cpp -o SLIC #把调试信息加到可执行文件中，如果没有-g，你将看不见程序的函数名、变量名，所代替的全是运行时的内存地址。
