108 # Logics of original test:
109 # Reveal that a query with SLEEP does not need less time than estimated.
111 # Bug#12689: SLEEP() gets incorrectly cached/optimized-away
113 # Description from bug report (slightly modified)
115 # Bug 1 (happened all time):
116 # SELECT * FROM t1 WHERE SLEEP(1) will only result in a sleep of 1
117 # second, regardless of the number of rows in t1.
118 # Bug 2 (happened all time):
119 # Such a query will also get cached by the query cache, but should not.
121 # Notes (mleich, 2008-05)
122 # =======================
125 # Bug#36345 Test 'func_misc' fails on RHAS3 x86_64
126 # showed that the tests for both bugs could produce in case of parallel
127 # artificial system time (like via ntpd)
128 # - decreases false alarm
129 # - increases false success
131 # We try here to circumvent these issues by reimplementation of the tests
132 # and sophisticated scripting, although the cause of the problems is a massive
133 # error within the setup of the testing environment.
134 # Tests relying on or checking derivates of the system time must never meet
135 # parallel manipulations of system time.
137 # Results of experiments with/without manipulation of system time,
138 # information_schema.processlist content, high load on testing box
139 # ----------------------------------------------------------------
140 # Definition: Predicted_cumulative_sleep_time =
141 # #_of_result_rows * sleep_time_per_result_row
143 # 1. Total (real sleep time) ~= predicted_cumulative_sleep_time !!
144 # 2. The state of a session within the PROCESSLIST changes to 'User sleep'
145 # if the sessions runs a statement containing the sleep function and the
146 # processing of the statement is just within the phase where the sleep
148 # 3. NOW() and processlist.time behave "synchronous" to system time and
149 # show also the "jumps" caused by system time manipulations. (*)
150 # 4. processlist.time is unsigned, the "next" value below 0 is ~ 4G (*)
151 # 5. Current processlist.time ~= current real sleep time if the system time
152 # was not manipulated. (*)
153 # 6. High system load can cause delays of <= 2 seconds.
154 # 7. Thanks to Davi for excellent hints and ideas.
157 # - information_schema.processlist is not available before MySQL 5.1.
158 # - Observation of processlist content requires a
159 # - "worker" session sending the query with "send" and pulling results
161 # - session observing the processlist parallel to the worker session
162 # "send" and "reap" do not work in case of an embedded server.
163 # Conclusion: Tests based on processlist have too many restrictions.
165 # Solutions for subtests based on TIMEDIFF of values filled via NOW()
166 # -------------------------------------------------------------------
167 # Run the following sequence three times
168 # 1. SELECT <start_time>
169 # 2. Query with SLEEP
170 # 3. SELECT <end_time>
171 # If TIMEDIFF(<end_time>,<start_time>) is at least two times within a
172 # reasonable range assume that we did not met errors we were looking for.
174 # It is extreme unlikely that we have two system time changes within the
