void set_persist_args_separator | ( | char ** | arg | ) |
void set_variable_source | ( | const char * | opt_name, |
void * | value | ||
) |
This function will set value for my_option::arg_source by doing a lookup into variables_hash based on opt_name as key.
If key is present corresponding value (config file, enum value) will be set in value.
[in] | opt_name | Pointer to option name. |
[out] | value | Pointer to struct holding config file path and variable source |
void update_variable_source | ( | const char * | opt_name, |
const char * | value | ||
) |
Track all options loaded from config files and command line options along with the path from where options are loaded.
For command line options path is empty string.
Ex: /etc/my.cnf has max_connections /$datadir/mysqld.auto.cnf has max_user_connections ./mysqld –server-id=47 with this setup, variables_hash has 3 entries of the above options along with path of config files and its enum value which is as below: max_connections -> (/etc/my.cnf , enum_variable_source::GLOBAL) max_user_connections -> ($datadir/mysqld.auto.cnf , enum_variable_source::PERSISTED) server-id -> ("" , enum_variable_source::COMMAND_LINE)
[in] | opt_name | Pointer to option name. opt_name must be in the form off –XXXXXX |
[in] | value | Pointer to config file path |

extern |
Holds a reference to the directory where the persisted configuration file is located.
This usually is the data directory. This is different from mysql_real_data_home mostly because it's passed down to mysys. And is also filled in a bit differently from mysql_real_data_home by Persisted_variables_cache::init()
