Detailed Description

Definitions of all server's session or global variables.

How to add new variables:

1. copy one of the existing variables, and edit the declaration. 2. if you need special behavior on assignment or additional checks use ON_CHECK and ON_UPDATE callbacks. 3. *Don't* add new Sys_var classes or uncle Occam will come with his razor to haunt you at nights

Note - all storage engine variables (for example myisam_whatever) should go into the corresponding storage engine sources (for example in storage/myisam/ !

Function Documentation

export bool fix_delay_key_write ( sys_var self,
THD *  thd,
enum_var_type  type 
When updating myisam_delay_key_write, we should do a 'flush tables' of all MyISAM tables to ensure that they are reopen with the new attribute.
void sql_mode_deprecation_warnings ( sql_mode_t  sql_mode)

If sql_mode is set throught the client, the deprecation warning should go to the client connection. If it is used as server startup option, it will go the error-log if the deprecated sql_modes are used.
