环境

  • vscode- gcc5.4
  • ubuntu16.04 或者 ubuntu18.04
  • make

下载6.2版本. 我使用的是国内github镜像地址：github.com.cnpmjs.org，速度比较快。

$ git clone https://github.com.cnpmjs.org/redis/redis.git redis
$ git checkout -b 6.2 remotes/origin/6.2

vscode不参与编译，只充当可视化的调试工具。

使用插件：

  • C/C++ 先编译redis
cd redis && make -j4

打开redis目录后直接按F5，会出现选择启动调试。选择c++(GDB/LLDB)
选择之后在左边的.vscode目录下会出现launch.json文件,将program修改为${workspaceFolder}/src/redis-server

{<!-- -->
    "version": "0.2.0",
    "configurations": [
        {<!-- -->
            "name": "(gdb) 启动",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/src/redis-server",
            "args": ["redis.conf"],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "setupCommands": [
                {<!-- -->
                    "description": "为 gdb 启用整齐打印",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        }
    ]
}

这样配置了之后可以按F5直接运行调试啦。

VScode编译调试redis

使用插件：

  • C/C++ 在.vscode目录下新建 tasks.json(“CFLAGS="-g -O0"“参数是为了编译debug版本),
{<!-- -->
    "version": "2.0.0",
    "tasks": [
        {<!-- -->
            "label": "build",
            "type": "shell",
            "command": "make",
            "args": [
                "CFLAGS=\"-g -O0\""
            ]
        }
    ]
}

修改launch.json->preLaunchTask: Build使得tasks.json可以被加载

{<!-- -->
    "version": "0.2.0",
    "configurations": [
        {<!-- -->
            "name": "(gdb) 启动",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/src/redis-server",
            "args": ["redis.conf"],
            "stopAtEntry": false,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "preLaunchTask": "build",
            "setupCommands": [
                {<!-- -->
                    "description": "为 gdb 启用整齐打印",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ]
        }
    ]
}

这样配置了之后可以按F5直接编译运行调试啦。
