# Bug#6760: Add SLEEP() function (feature request)
#
#   Logics of original test:
#   Reveal that a query with SLEEP does not need less time than estimated.
#
# Bug#12689: SLEEP() gets incorrectly cached/optimized-away
#
#   Description from bug report (slightly modified)
#
#   Bug 1 (happened all time):
#      SELECT * FROM t1 WHERE SLEEP(1) will only result in a sleep of 1
#      second, regardless of the number of rows in t1.
#   Bug 2 (happened all time):
#      Such a query will also get cached by the query cache, but should not.
#
# Notes (mleich, 2008-05)
# =======================
#
# Experiments around
#    Bug#36345 Test 'func_misc' fails on RHAS3 x86_64
# showed that the tests for both bugs could produce in case of parallel
# artificial system time (like via ntpd)
# - decreases false alarm
# - increases false success
#
# We try here to circumvent these issues by reimplementation of the tests
# and sophisticated scripting, although the cause of the problems is a massive
# error within the setup of the testing environment.
# Tests relying on or checking derivates of the system time must never meet
# parallel manipulations of system time.
#
# Results of experiments with/without manipulation of system time,
# information_schema.processlist content, high load on testing box
# ----------------------------------------------------------------
# Definition: Predicted_cumulative_sleep_time =
#                #_of_result_rows * sleep_time_per_result_row
#
# 1. Total (real sleep time) ~= predicted_cumulative_sleep_time !!
# 2. The state of a session within the PROCESSLIST changes to 'User sleep'
#    if the sessions runs a statement containing the sleep function and the
#    processing of the statement is just within the phase where the sleep
#    is done. (*)
# 3. NOW() and processlist.time behave "synchronous" to system time and
#    show also the "jumps" caused by system time manipulations. (*)
# 4. processlist.time is unsigned, the "next" value below 0 is ~ 4G (*)
# 5. Current processlist.time ~= current real sleep time if the system time
#    was not manipulated. (*)
# 6. High system load can cause delays of <= 2 seconds.
# 7. Thanks to Davi for excellent hints and ideas.
#
#    (*)
#    - information_schema.processlist is not available before MySQL 5.1.
#    - Observation of processlist content requires a
#      - "worker" session sending the query with "send" and pulling results
#        with "reap"
#      - session observing the processlist parallel to the worker session
#      "send" and "reap" do not work in case of an embedded server.
#    Conclusion: Tests based on processlist have too many restrictions.
#
# Solutions for subtests based on TIMEDIFF of values filled via NOW()
# -------------------------------------------------------------------
# Run the following sequence three times
#    1. SELECT <start_time>
#    2. Query with SLEEP
#    3. SELECT <end_time>
# If TIMEDIFF(<end_time>,<start_time>) is at least two times within a
# reasonable range assume that we did not met errors we were looking for.
#
# It is extreme unlikely that we have two system time changes within the
# < 30 seconds runtime. Even if the unlikely happens, there are so
# frequent runs of this test on this or another testing box which will
# catch the problem.
