LP:702084 - myisam_block_size is not reported in SHOW GLOBAL VARIABLES

When we were playing around with the various MyISAM features we found that the server option myisam_block_size is not reported at all in the output of SHOW GLOBAL VARIABLES.

This was already discussed in bug #33098 http://bugs.mysql.com/bug.php?id=33098 but never fixed.

And from the user point of view I do not care if this is a variable or an option. I just want to see it in show global variables.

I was looking in the code to see if I can write a patch. But I have not found the reason, why this server option is not displayed but others are:

mysqld.cc

741 static ulong opt_specialflag, opt_myisam_block_size;

7195

{"myisam_block_size", OPT_MYISAM_BLOCK_SIZE, 7196 "Block size to be used for MyISAM index pages.", 7197 &opt_myisam_block_size, &opt_myisam_block_size, 0, GET_ULONG, REQUIRED_ARG, 7198 MI_KEY_BLOCK_LENGTH, MI_MIN_KEY_BLOCK_LENGTH, MI_MAX_KEY_BLOCK_LENGTH, 7199 0, MI_MIN_KEY_BLOCK_LENGTH, 0}

,

9201 myisam_block_size=(uint) 1 << my_bit_log2(opt_myisam_block_size);

I hope somebody takes care about?
