+# Purpose of include/ddl1.inc - include/ddl8.inc:
+#
+#    Stress storage engines with rapid CREATE/DROP TABLE/INDEX
+#    and following SELECT/INSERT/SHOW etc.
+#
+# The variables
+#     $loop_size -- number of rounds till we look at the clock again
+#     $runtime   -- rough intended runtime per subtest variant
+#                Real runtime without server restarts and comparison is:
+#                   -   >= $runtime
+#                   -   > runtime needed for $loop_size execution loops
+#     $engine_type -- storage engine to be used in CREATE TABLE
+# must be set within the routine sourcing this script.
+#
+# Other stuff which must already exist:
+# - connection con2
+# - stmt_start and stmt_break prepared by the default connection
+#
+# Attention:
+#    The test does suppress the writing of most statements, server error
+#    messages and result sets.
+#    This is needed because their number is usual not deterministic.
+#    The test is partially self checking. That means is prints some
+#    helpful hints into the protocol and aborts if something is wrong.

+############################################################################
+#
+# Some details:
+#
+# 1. Base question of the test:
+#       There was just a create or drop of some object (TABLE/INDEX).
+#
+#       Could it happen that the next statement referring to this
+#       object gets a somehow wrong server response (result set,
+#       error message, warning) because the creation or removal of
+#       the object is in an incomplete state?
+#
+#       Thinkable reasons for incomplete state of creation or removal:
+#       The server performs the creation or removal
+#       - all time incomplete.
+#         Example:
+#            Bug#28309 First insert violates unique constraint
+#                      - was "memory" table empty ?
+#       - asynchronous
+#         In that case the next statement has probably to wait till
+#         completion.
+#
+# 2. Why do we use in some scripts "--error 0,<expected error>" followed
+#    a check of $mysql_errno?
+#
+#    System reactions when running with "--error 0,<expected error>":
+#    - RC=0 --> no error message
+#    - RC=<expected error> --> no error message
+#    - RC not in (0,<expected error>) --> error message + abort of script
+#                                         execution
+#
+#    Requirements and tricky solution for statements which are expected
+#    to fail:
+#    1. RC=<expected error>
+#       - no abort of script execution
+#         --> add "--error <expected error>"
+#       - no error message into the protocol, because the number of
+#         executions is NOT deterministic
+#         --> use "--error 0,<expected error>"
+#    2. RC=0 = failure
+#       - abort of script execution
+#       "--error 0,<expected error>" prevents the automatic abort of
+#       execution. Therefore we do not need to code the abort.
+#       --> Check $mysql_errno and do an explicit abort if $mysql_errno = 0.
+#    3. RC not in (0,<expected error>)
+#       - abort of script execution
+#       "--error 0,<expected error>" causes an automatic abort.
+#
+# 3. We do not check the correctness of the SHOW CREATE TABLE output
+#    in detail. This must be done within other tests.
+#    We only check here that
+#    - same CREATE TABLE/INDEX statements lead to the same
+#    - different CREATE TABLE/INDEX statements lead to different
+#    SHOW CREATE TABLE output
+#    (Applies to ddl4.inc. and ddl8.inc.)
+#
+# 4. It could be assumed that running this test with
+#    - PS-PROTOCOL
+#      There are already subtests using prepared statements contained.
+#    - SP/CURSOR/VIEW-PROTOCOL
+#      These protocol variants transform SELECTs to hopefully much
+#      stressing statement sequencies using SP/CURSOR/VIEW.
+#      The SELECTs within include/ddl*.inc are very simple.
+#    does not increase the coverage.
+#    Therefore we skip runs with these protocols.
+#
+# 5. The test consumes significant runtime when running on a non RAM
+#    based filesystem (run without "--mem").
+#    Therefore we adjust $runtime and $loop_size depending on "--big-test"
+#    option.
+#    $runtime and $loop_size do not influence the expected results.
+#    Rough runtime in seconds reported by mysql-test-run.pl:
+#        (engine_type = MEMORY)
+#    option set    -> $runtime $loop_size  real runtime in seconds
+#                         1        20             68
+#    --mem                1        20             32
+#          --big-test     5       100            200
+#    --mem --big-test     5       100            400
+#    I assume that runs with slow filesystems are as much valuable
+#    as runs with extreme fast filesystems.
+#
+# 6. Hints for analysis of test failures:
+#    1. Look into the protocol and check in which ddl*.inc
+#       script the difference to the expected result occured.
+#    2. Comment the sourcing of all other ddl*.inc scripts
+#       out.
+#    3. Edit the ddl*.inc script where the error occured and
+#       remove all
+#       - "--disable_query_log", "--disable_result_log"
+#       - successful passed subtests.
+#    4. Alternative:
+#       Have a look into VARDIR/master-data/mysql/general_log.CSV
+#       and construct a new testcase from that.
+#    5. If the problem is not deterministic, please try the following
+#       - increase $runtime (important), $loop_size (most probably
+#         less important) within the "t/ddl_<engine>.test" and
+#         maybe the "--testcase-timeout" assigned to mysqltest-run.pl
+#       - vary the I/O performance of the testing machine by using
+#         a RAM or disk based filesystem for VARDIR
