-------------------------------------------------------------------------------- /docs/docs/game/debug-output.md: -------------------------------------------------------------------------------- 1 | --- 2 | title: 输出调试信息 3 | --- 4 | 5 | 本篇文档介绍如何向[训练营](https://open.oceanbase.com/train)输出调试信息。 6 | 7 | 在使用训练营提交测试时，有时候会遇到本地环境没有问题，但是训练营上的输出总是不符合预期。但是训练营没有办法调试，这时候就需要在训练营上输出调试信息，以便于定位问题。 8 | 9 | **如何输出调试信息** 10 | 11 | 可以参考文件 `sql_debug.h`，在需要输出调试信息的地方，调用`sql_debug`函数即可。sql_debug 的使用与打印日志类似，不过可以在向客户端输出正常结果后，再输出调试信息。 12 | 执行`sql_debug`同时会在日志中打印DEBUG级别的日志。 13 | 14 | **示例** 15 | 16 | 1. `CreateTableStmt::create` 17 | 2. `TableScanPhysicalOperator::next` 18 | 19 | **注意** 20 | 由于训练营上能够容纳的信息有限，所以输出太多信息会被截断。 21 | 22 | **开关** 23 | 24 | 每个连接都可以开启或关闭调试，可以参考 `Session::sql_debug_`。 25 | 26 | 在交互式命令行中，可以使用 `set sql_debug=1` 开启调试，使用 `set sql_debug=0` 关闭调试。 27 | 28 | > 当前没有实现查看变量的命令。 29 | 30 | 示例 31 | 32 | ```bash 33 | miniob > select * from t; 34 | id 35 | 1 36 | 37 | # get a tuple: 1 38 | miniob > set sql_debug=0; 39 | SUCCESS 40 | miniob > select * from t; 41 | id 42 | 1 43 | 44 | ``` 45 | 46 | 在训练营中，需要手动修改 `session.h` 文件中的代码来开启调试/关闭调试。 47 | ```c++ 48 | // 将 Session::sql_debug_ 设置为 false，关闭调试 49 | bool sql_debug_ = false; 50 | // 将 Session::sql_debug_ 设置为 true，开启调试 51 | bool sql_debug_ = true; 52 | ```
