if you looking for something simple, consider new_mode:
if (thd->variables.new_mode)
return new_mysql_alter_table(...)
else
return old_mysql_alter_table(...)
Or old_mode:
if (!global_system_variables.old_mode)
return new_mysql_alter_table(...)
else
return old_mysql_alter_table(...)
Or old_alter_table:
if (!thd->variables.old_alter_table)
return new_mysql_alter_table(...)
else
return old_mysql_alter_table(...)
All these already exist as mysqld command line options and system
variables. First and third are session variables, second is a global one.
