Bug#21789221 SHOW STATUS FAILS WITH LOCK TABLES AND SHOW_COMPATIBILITY_56=OFF
================================================================================
Verify that SHOW STATUS and SHOW VARIABLES works under LOCK TABLES mode
CREATE TABLE test.t1 (s1 INT);
LOCK TABLE test.t1 READ;
SHOW GLOBAL STATUS WHERE VARIABLE_NAME LIKE "foo";
Variable_name Value
SHOW SESSION STATUS WHERE VARIABLE_NAME LIKE "foo";
Variable_name Value
SHOW GLOBAL VARIABLES WHERE VARIABLE_NAME LIKE "foo";
Variable_name Value
SHOW SESSION VARIABLES WHERE VARIABLE_NAME LIKE "foo";
Variable_name Value
UNLOCK TABLES;
LOCK TABLE test.t1 WRITE;
SHOW GLOBAL STATUS WHERE VARIABLE_NAME LIKE "foo";
Variable_name Value
SHOW SESSION STATUS WHERE VARIABLE_NAME LIKE "foo";
Variable_name Value
SHOW GLOBAL VARIABLES WHERE VARIABLE_NAME LIKE "foo";

Bug#28515475 BOGUS DATA WHEN ORDERING RESULTS FROM VARIABLES_BY_THREAD
================================================================================
Verify the results from "WHERE variable_name IN(...)", particularly for those
variables that are listed after the deprecated variable gtid_executed.
The ORDER BY also forces an additional code path through rnd_pos().
SELECT variable_name FROM performance_schema.variables_by_thread
WHERE variable_name IN ('interactive_timeout','net_read_timeout','net_write_timeout','wait_timeout')
ORDER BY variable_name;
variable_name
interactive_timeout
net_read_timeout
net_write_timeout
wait_timeout
