+# SELECT col2 FROM mysqltest.my_aux WHERE col1 = -1
+# Both statements differ in the statement length.

+# SELECT col2 FROM mysqltest.my_aux WHERE col1 = 2
+# SELECT col2 FROM mysqltest.my_aux WHERE col1 = 1
+# Both statements have the same length.

+# SELECT col2 FROM mysqltest.my_aux WHERE col1 = 1

+# SELECT col2 FROM mysqltest.my_aux WHERE col1 = 1
+# Both statements have the same length.
+# One statement earns an one row containing an empty string.
+# The other statement earns two rows containing an empty string.
+# 4.5 Check the differences caused by Connects
+# Attention: Succesful Connects run an additional "DO 1".
+# 4.5.1 Connects do not charge anything into READ or WRITE counters
+# of the instance with EVENT_NAME NOT LIKE ('%client_connection%').
+# This mean all these counters must be 0.
+# 4.5.2 Connects using for host the value 'localhost'
+# 4.5.2.1 For the instance with EVENT_NAME LIKE '%server_tcpip_socket'
+# COUNT_MISC = 0 AND SUM_TIMER_MISC = 0 must be valid
+# because we run through server_unix_socket.
+# 4.5.2.2 For the instance with EVENT_NAME LIKE '%server_unix_socket'
+# COUNT_MISC > 0 AND SUM_TIMER_MISC > 0 must be valid.
+# SKIPPED FOR WINDOWS
+# 4.5.3 Connects using for host a value <> 'localhost'
+# 4.5.3.1 For the instance with EVENT_NAME LIKE '%server_unix_socket'
+# COUNT_MISC = 0 AND SUM_TIMER_MISC = 0 must be valid
+# because we run through server_tcpip_socket.
+# SKIPPED FOR WINDOWS
+# 4.5.3.2 For the instance with EVENT_NAME LIKE '%server_tcpip_socket'
+# COUNT_MISC > 0 AND SUM_TIMER_MISC > 0 must be valid.
+# 4.5.4 Failing Connects do not cause any row with EVENT_NAME
+# LIKE '%client_connection'
+# 4.5.5 Successful Connects cause a new instance with EVENT_NAME
+# LIKE '%client_connection'
+# 4.6 Check the differences caused by Connects
+# - INSTANCES with an EVENT_NAME like server_tcpip_socket or
+# server_unix_socket are already checked
+# - the stability of results is already checked
+# So we con go with the results of the first run.
+# 4.6.1 The SUM_OF_BYTES_WRITE value is the same for all Connects.
+# 4.6.2 The SUM_OF_BYTES_WRITE value hast to be > 100.
+# 4.6.3 COUNT_READ, COUNT_WRITE and COUNT_MISC have to be to be > 0
+# 4.6.4 Checks based on comparison of results for connects
+# 4.6.4 The user name length affects the SUM_OF_BYTES_READ value
+# 4.6.5 The database name length affects the SUM_OF_BYTES_READ value

+# Some functional checks for the content of the performance_schema table
+# socket_summary_by_instance.
+#
+# Created: mleich 2011-07-01
+#
+# Rough description of "What is when tested"
+# 1. Impact of successful connect
+# A new row with EVENT_NAME "client_connection" shows up
+# is tested in 0 and 4.5.
+# 2. Impact of disconnect
+# A row with EVENT_NAME "client_connection" disappears up
+# is tested in 0. and 1.2.
+# 3. Disabling the instrumentation for some thread causes that the
+# counter for this thread become static is tested in 4.3.
+# Nearby the beginning of this test and somewhere in the middle.
+# 4. TRUNCATE table resets the counter is tested nearby the beginning.
+# 5. Consistency within a row like MIN_* <= AVG_* <= MAX_*
+# -> include/socket_summary_check.inc which is called at
+# various places
+# 6. Consistency of the instances mentioned in socket_summary_by_event
+# and socket_summary_by_instance is checked per call of
+# include/socket_summary_check.inc
+# 7. Check if changes in counters of instances caused by actions
+# are reasonable is tested for
+# - Connects+SQL statements in 4.1 and 4.2
+# - SQL statements in 4.4
+# - Connects in 4.5
