在学习编译和调试MYSQL源码的时候,我们是先有了鸡,才去找蛋!
是你知道了函数名,然后给它打个断点,然后去调试,步步追随!
以下两种调试方法
用VSCODE 编辑编译调试MYSQL8
这个用IDE的 需要一个干净的环境才好
这个是用LINUX下 编译查看源码的 主要使用GDB命令
假设 你想知道一个SQL语句到底要执行哪些函数呢? 那么就要使用MYSQL
TRAC功能了
要开启MYSQL TRAC功能 需要DEBUG版本
那我们上面的工作是有价值意义的.
在 shell 命令行指定调试控制字符串，示例：
--debug=d:t
--debug=d:f,main,subr1:F:L:t,20
--debug=d,input,output,files:n
--debug=d:t:i:O,\\mysqld.trace复制
对于mysqld，也可以通过设置debug系统变量在运行时更改DBUG设置。此变量具有全局值和会话值：
mysql> SET GLOBAL debug = 'debug_options';
mysql> SET SESSION debug = 'debug_options';复制
debug_options值是一系列冒号分隔的字段，值中的每个字段都由一个强制标志字符组成，前面可选+或-字符，后面可选逗号分隔的修饰符列表
[+|-]flag[,modifier,modifier,...,modifier]复制
下表介绍标志字符。无法识别的标志字符将被自动忽略。
这些东西稍微看看,不要死记硬背,看不懂意思也就算了,没啥大不了的,当作手册,以后可查!
| 标识字符 | 描述 |
| d | 为当前状态启用DBUG_XXX宏的输出。后面可能会有一个关键字列表，该列表仅为具有该关键字的DBUG宏启用输出。关键字的空列表启用所有宏的输出.在MySQL中，要启用的常见调试宏关键字有enter、exit、error、warning、info和loop。如：set debug = 'd,info'; 获取代码中DBUG_PRINT("info:" 打印的日志） |
| D | 每个调试器输出行之后的延迟。论点是延迟，以十分之一秒为单位，取决于机器的能力。例如，D，20指定两秒的延迟。 |
| f | 将调试、跟踪和分析限制在命名函数列表中。空列表启用所有功能。仍然必须给出适当的d或t标志；此标志仅在启用时限制其操作。 |
| F | 标识每行调试或跟踪输出的源文件名。 |
| i | 用每行调试或跟踪输出的PID或线程ID标识进程 |
| L | 标识调试或跟踪输出每行的源文件行号 |
| n | 打印每行调试或跟踪输出的当前函数嵌套深度 |
| N | 对调试输出的每行进行编号 |
| o | 将调试器输出流重定向到指定文件。默认输出为stderr |
| O | 与o类似，但文件在每次写入之间都会被刷新。需要时，在每次写入之间关闭并重新打开文件 |
| P | 将调试器操作限制为指定进程。一个进程必须用DBUG_进程宏标识，并与列表中的一个进程匹配，才能执行调试器操作 |
| p | 打印每行调试或跟踪输出的当前进程名称 |
| r | 推送新状态时，不要继承以前状态的函数嵌套级别。当输出从左边距开始时有用。 |
| S | 在每个已调试的函数上执行函数_sanity（_file_，_line_））直到_sanity（）返回与0不同的内容 |
| t | 启用函数调用/退出跟踪线。后面可能会有一个列表（仅包含一个修饰符），给出数字最大跟踪级别，超过该级别，调试或跟踪宏都不会出现输出。默认为编译时选项。 |
前导+或-字符和尾随修饰符列表用于标志字符，如d或f，可以对所有适用修饰符或其中一些修饰符启用调试操作：
如果没有前导+或-，则标志值将精确设置为给定的修饰符列表。使用前导+或-，列表中的修饰符将添加到当前修饰符列表或从中减去
以下示例显示了这如何适用于d标志。为所有调试宏启用了空d列表输出。非空列表仅为列表中的宏关键字启用输出。
这些语句将d值设置为给定的修饰符列表：
mysql> SET debug = 'd';
mysql> SELECT @@debug;
+---------+
| @@debug |
+---------+
| d |
+---------+
mysql> SET debug = 'd,error,warning';
mysql> SELECT @@debug;
+-----------------+
| @@debug |
+-----------------+
| d,error,warning |
+-----------------+复制
删除标志符号
mysql> SET debug = '+d,loop';
mysql> SELECT @@debug;
+----------------------+
| @@debug |
+----------------------+
| d,error,warning,loop |
+----------------------+
mysql> SET debug = '-d,error,loop';
mysql> SELECT @@debug;
+-----------+
| @@debug |
+-----------+
| d,warning |
+-----------+复制
复制
set debug = 'd:t:o,/tmp/mysqld.trace'; 只对当前会话生效，只对当前执行的语句 trace。复制
结果比较清晰复制
复制
我们玩一把复制
mysql> set debug = 'd:t:F:i:L:n:p:o,/root/mysqld.trace';
