# Tests for PERFORMANCE_SCHEMA stored programs instrumentation  
#-------------------------------------------------------------

#
#  Test case to show the behaviour of stored program instrumentation 
#  when values of the system variables performance_schema_max_program_instances & 
#  performance_schema_max_statement_stack are less than the statistics collected. 
#  The status of the lost instrumentation is shown through the status variables
#  performance_schema_program_lost & performance_schema_nested_statement_lost
#  

# Restarting the server at the begining of the test.
# This is to avoid the instrumentation of extra SPs called by MTR 
# These additional stored programs which will be added might cause 
# result content mismatch failure.
