How to use vscode for developing
参考插件：
以下设置基于这些插件。
参考.vscode/setting.json
{
"cmake.cmakePath": "${workspaceFolder}/deps/3rd/usr/local/oceanbase/devtools/bin/cmake",
"cmake.parallelJobs": 6,
"cmake.generator": "Unix Makefiles",
"cmake.buildDirectory": "${workspaceFolder}/build_debug",
"cmake.configureArgs": [
"-DCMAKE_BUILD_TYPE=Debug",
"-DOB_USE_LLD=ON",
"-DOB_BUILD_UNITTEST=ON"
],
"C_Cpp.default.compilerPath": "${workspaceFolder}/deps/3rd/usr/local/oceanbase/devtools/bin/clang++",
"C_Cpp.default.configurationProvider": "ms-vscode.cmake-tools",
"cmake.debugConfig": {
"MIMode": "gdb",
"miDebuggerPath": "/usr/bin/gdb",
}
}参考.vscode/launch.json

"stopAtEntry": false,
// working dirctory resolved by CMake Tools.
"cwd": "${command:cmake.getLaunchTargetDirectory}",
// configure source file map manually to walk around debug files
// not found bug in vscode.
// Here shows an example for debugging source files in sql/parser
"sourceFileMap":{
"./build_debug/unittest/sql/parser/./unittest/sql/parser": {
"editorPath": "${workspaceFolder}/unittest/sql/parser"
},
"./build_debug/src/sql/parser/./src/sql/parser": {

},
},
"environment": [
{
// add the directory where our target was built to the PATHs
// it gets resolved by CMake Tools:

},
],
"MIMode": "gdb",

{

// traditional debug configuration: set target manually.
{

}使用attach request

{

{

"text": "-enable-pretty-printing",
"ignoreFailures": true
}
],
"sourceFileMap": {
"./build_debug/src/observer/./src/observer/omt": {
"editorPath": "${workspaceFolder}/src/observer/omt"
},
"./build_debug/src/sql/parser/./src/sql/parser": {
"editorPath": "${workspaceFolder}/src/sql/parser",
"useForBreakpoints": true
},
"./build_debug/src/sql/./src/sql": {
"editorPath": "${workspaceFolder}/src/sql",
"useForBreakpoints": true
},
"./build_debug/src/sql/engine/expr/./src/sql/engine/expr": {
"editorPath": "${workspaceFolder}/src/sql/engine/expr",
"useForBreakpoints": true
},
"./build_debug/src/storage/./src/storage": {
"editorPath": "${workspaceFolder}/src/storage",
"useForBreakpoints": true
},
"./build_debug/src/observer/./src/observer/mysql": {
"editorPath": "${workspaceFolder}/src/observer/mysql",
"useForBreakpoints": true
},
"./build_debug/deps/oblib/src/rpc/./deps/oblib/src/rpc/": {
"editorPath": "${workspaceFolder}/deps/oblib/src/rpc/",
"useForBreakpoints": true
},
"./build_debug/src/observer/./deps/oblib/src/lib/allocator/": {
"editorPath": "${workspaceFolder}/deps/oblib/src/lib/allocator",
"useForBreakpoints": true
},
"./build_debug/deps/oblib/src/lib/./deps/oblib/src/lib/": {
"editorPath": "${workspaceFolder}/deps/oblib/src/lib",
"useForBreakpoints": true
},
"./build_debug/src/storage/./src/sql/engine/basic": {
"editorPath": "${workspaceFolder}/src/sql/engine/basic",
"useForBreakpoints": true
}
}
}
],
"inputs": [
{
"id": "FindPID",
"type": "command",
"command": "shellCommand.execute",
"args": {
"command": "ps -aux | grep /bin/observer | grep -v grep | awk '{print $2}'",
"description": "Select your observer PID",
"useFirstResult": true,
}
}
]
}如果想通过写Debug历程验证一些东西可以使用此方法：
- 在某个源码文件夹添加新的源码文件
- 在对应文件夹下Cmake文件中添加编译目标
- 上方为功能区;
- 下方为调试入口，右边选择target.
