## Test the Performance Schema-based implementation of SHOW PROCESSLIST.
|
|
##
|
|
## Verify handling of the SELECT and PROCESS privileges.
|
|
##
|
|
## Test cases:
|
|
## - Execute SHOW PROCESSLIST (new and legacy) with all privileges
|
|
## - Execute SELECT on the performance_schema.processlist and information_schema.processlist with all privileges
|
|
## - Execute SHOW PROCESSLIST (new and legacy) with no privileges
|
|
## - Execute SELECT on the performance_schema.processlist and information_schema.processlist with no privileges
|
|
##
|
|
## Results must be manually verified.
|
