# 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.
