Bug #59677	Table name case sensitive in grant privileges on mac

Category:	MySQL Server: Security: Privileges	Severity:	S2 (Serious)
Version:	5.1.41, 5.5.8	OS:	MacOS
Assigned to:		CPU Architecture:	Any

Description:
Granting privileges on a table which has uppercase letters on mac results in client not able to query. The testing was done on: 5.0.77, 5.1.35,40,41,42,44,45,50, 5.5.8 and 6.0.11 and found to have started as from 5.1.41, still an issue with 5.5.8 but not on 6.0.11.

How to repeat:
as user with grant option:

create database testing;
use testing
create table table1(a int);
create table Table2(a int);
grant select on testing.table1 to 'dc'@'localhost';
grant select on testing.Table2 to 'dc'@'localhost';

as dc from localhost:
use testing
show tables;

This is not specific for Mac. Same on Windows with 'lower_case_table_names' = 2 setting in configuration (on both 5.1.54 and 5.5.8):

5.5.8:

SHOW VARIABLES LIKE 'lower_case_table_names'; -- returns 2
SHOW GRANTS; 
/*
Grants for dc@localhost                               
------------------------------------------------------
GRANT USAGE ON *.* TO 'dc'@'localhost'                
GRANT SELECT ON `testing`.`table1` TO 'dc'@'localhost'
GRANT SELECT ON `testing`.`table2` TO 'dc'@'localhost'
*/

USE testing;
SHOW TABLES;

/* returrns

Tables_in_testing
-----------------
table1           
*/

All the *ever returning* issues with 'lower_case_table_names' in MySQL since 4.0 are so annoying (and also unforgivable *STUPID* and *UNATTENTIVE* (as there are more than enough reports already with 'lower_case_table_names' -issues). 

To pin it out:

1) SHOW GRANTS should return table names in *mixed case* as tables were created.
2) SHOW TABLES should return both tables (and also in *mixed case*).

One more detail:

SHOW GRANTS;
/*
Grants for dc@localhost                               
------------------------------------------------------
GRANT USAGE ON *.* TO 'dc'@'localhost'                
GRANT SELECT ON `testing`.`table1` TO 'dc'@'localhost'
*/

USE testing;
SELECT * FROM table2; -- succeeds with any lettercase.

I missed a line in my  output.  it hsould be 

Grants for dc@localhost                               
------------------------------------------------------
GRANT USAGE ON *.* TO 'dc'@'localhost'                
GRANT SELECT ON `testing`.`table1` TO 'dc'@'localhost'
GRANT SELECT ON `testing`.`table2` TO 'dc'@'localhost'

The problem is that SHOW and SELECT FROM I_S does not respect 'lower_case_table_names' setting.

.. and also that SHOW GRANTS does not.

Thank you for the report.

Please provide output of SHOW TABLES in your environment. I get both tables:

$mysql51 -udc testing
Reading table information for completion of table and column names
