MAX_FULL_NAME_LEN in InnoDB to address possible insufficient name buffer

Bug #59312 Approved by Sunny Bains

Problem: master executed a statement that would fail on slave
(namely, DROP USER 'create_rout_db'@'localhost').
Then the test did:
  --let $rpl_only_running_threads= 1
  --source include/rpl_reset.inc
rpl_reset.inc calls rpl_sync.inc, which first checks which of
the threads are running and then syncs those threads that are
running. If the SQL thread fails after the check, the sync will
fail. So there was a race in the test and it failed on some
slow hosts.
Fix: Don't replicate the failing statement.

Item_sum_max/Item_sum_min incorrectly set null_value flag and
attempt to get result in parent functions leads to crash.
This happens due to double evaluation of the function argumet.
First evaluation happens in the comparator and second one
happens in Item_cache::cache_value().
The fix is to introduce new Item_cache object which
holds result of the argument and use this cached value
as an argument of the comparator.

mysql-test/r/func_group.result:
  test case
mysql-test/t/func_group.test:
  test case
sql/item.cc:
  added assertion that ether we have some result or result is NULL.
sql/item_sum.cc:
  introduce new Item_cache object which
  holds result of the argument and use this cached value
  as an argument of the comparator.
sql/item_sum.h:
  introduce new Item_cache object which
  holds result of the argument and use this cached value
  as an argument of the comparator.

Normally, auto_increment value is generated for the column by
inserting either NULL or 0 into it. NO_AUTO_VALUE_ON_ZERO
suppresses this behavior for 0 so that only NULL generates
the auto_increment value. This behavior is also followed by
a slave, specifically by the SQL Thread, when applying events
in the statement format from a master. However, when applying
events in the row format, the flag was ignored thus causing
an assertion failure:
"Assertion failed: next_insert_id == 0, file .\handler.cc"

In fact, we never need to generate a auto_increment value for
the column when applying events in row format on slave. So we
don't allow it to happen by using 'MODE_NO_AUTO_VALUE_ON_ZERO'.

Refactoring: Get rid of all the sql_mode checks to rows_log_event
when applying it for avoiding problems caused by the inconsistency
of the sql_mode on slave and master as the sql_mode is not set for
Rows_log_event.

mysql-test/extra/rpl_tests/rpl_auto_increment.test:
  Added test to verify if the assertion of "next_insert_id == 0"
  will fail in ha_external_lock() function.
mysql-test/suite/rpl/r/rpl_auto_increment.result:
  Test result for bug#56662.
sql/log_event.cc:
  Added code to not allow generation of auto_increment value when
  processing rows event by adding 'MODE_NO_AUTO_VALUE_ON_ZERO' to
  sql_mode.
sql/rpl_record.cc:
  Added code to get rid of the 'MODE_STRICT_TRANS_TABLES'  and
  MODE_STRICT_ALL_TABLES check to the table when appling the
  rows event and treat it as no strict.

Problem: Warnings for truncated data were generated on hosts with
long host names because @@hostname was inserted into a CHAR(40) column.
Fix: Change CHAR(40) to TEXT.

Major replication test framework cleanup. This does the following:
 - Ensure that all tests clean up the replication state when they
   finish, by making check-testcase check the output of SHOW SLAVE STATUS.
   This implies:
    - Slave must not be running after test finished. This is good
      because it removes the risk for sporadic errors in subsequent
      tests when a test forgets to sync correctly.
    - Slave SQL and IO errors must be cleared when test ends. This is
      good because we will notice if a test gets an unexpected error in
      the slave threads near the end.
    - We no longer have to clean up before a test starts.
 - Ensure that all tests that wait for an error in one of the slave
   threads waits for a specific error. It is no longer possible to
   source wait_for_slave_[sql|io]_to_stop.inc when there is an error
   in one of the slave threads. This is good because:
    - If a test expects an error but there is a bug that causes
      another error to happen, or if it stops the slave thread without
      an error, then we will notice.
    - When developing tests, wait_for_*_to_[start|stop].inc will fail
      immediately if there is an error in the relevant slave thread.
      Before this patch, we had to wait for the timeout.
 - Remove duplicated and repeated code for setting up unusual replication
   topologies. Now, there is a single file that is capable of setting
   up arbitrary topologies (include/rpl_init.inc, but
   include/master-slave.inc is still available for the most common
   topology). Tests can now end with include/rpl_end.inc, which will clean
   up correctly no matter what topology is used. The topology can be
   changed with include/rpl_change_topology.inc.
 - Improved debug information when tests fail. This includes:
    - debug info is printed on all servers configured by include/rpl_init.inc
    - User can set $rpl_debug=1, which makes auxiliary replication files
      print relevant debug info.
 - Improved documentation for all auxiliary replication files. Now they
   describe purpose, usage, parameters, and side effects.
 - Many small code cleanups:
    - Made have_innodb.inc output a sensible error message.
    - Moved contents of rpl000017-slave.sh into rpl000017.test
    - Added mysqltest variables that expose the current state of
      disable_warnings/enable_warnings and friends.
    - Too many to list here: see per-file comments for details.


client/mysqltest.cc:
  Added the following variables:
   $ENABLED_WARNINGS
   $ENABLED_QUERY_LOG
   $ENABLED_RESULT_LOG
   $ENABLED_ABORT_ON_ERROR
   $ENABLED_INFO
   $ENABLED_METADATA
  Each variable is 0 or 1, depending on if the corresponding
  mysqltest feature is on or off.

mysql-test/extra/rpl_tests/rpl_get_master_version_and_clock.test:
   - Replace 'start slave; wait_for_slave_to_start.inc' by
     include/start_slave.inc.
   - Use new file rpl_connect.inc to reconnect on all connections, since the
     connections are used by rpl_end.inc.
   - Use wait_for_slave_param.inc instead of wait_for_slave_io_to_start.inc,
     since wait_for_slave_io_to_start.inc now fails if the IO thread has
     an error. In this particular test case, it is normal that the IO thread
     has an error.
   - Changed wait_for_slave_io_error.inc so that it waits
     for the IO thread to stop. However, in this test case,
     the IO thread only gets a non-fatal error, so it does
     not stop. So we set $slave_io_error_is_nonfatal=1 to
     prevent wait_for_slave_io_error.inc from waiting.

     instead of wait_for_slave_sql_to_stop.inc
   - Use check_slave_no_error.inc instead of print errors
     to the log.
   - Use rpl_reset.inc instead of master-slave-reset.inc
     This means we have to clear the error from the slave
     threads by calling RESET SLAVE explicitly.
   - diff_tables.inc now takes only one parameter.

mysql-test/extra/rpl_tests/rpl_reset_slave.test:
  - replace wait_for_slave_io_error.inc+stop_slave.inc by
    wait_for_slave_io_error_and_stop.inc+stop_slave_sql.inc
    since stop_slave.inc now fails when the io thread has an
    error.
  - replace stop_slave.inc by STOP SLAVE +
    wait_for_slave_sql_to_stop.inc +
    wait_for_slave_param. stop_slave.inc would fail since
    the IO thread has an error.
  - add include/rpl_end.inc to clean up replication state
mysql-test/extra/rpl_tests/rpl_row_UUID.test:
  Don't clean up replication here since this file does not setup

  cosmetic fixes
mysql-test/extra/rpl_tests/rpl_truncate_helper.test:
  - replace reset_master_and_slave.inc by rpl_reset.inc

mysql-test/include/analyze-sync_with_master.test:
  - improved debug output printed when sync_slave_with_master or
    sync_with_master fails
  - Added documentation
mysql-test/include/assert.inc:
  Added file to facilitate assertions.
mysql-test/include/begin_include_file.inc:
  New auxiliary file to be used by replication helper files like
  rpl_init.inc, stop_slave.inc, wait_for_slave_*.inc, etc. Such
  helper files should source rpl_begin_include_file.inc at the
  beginning and rpl_end_include_file.inc at the end. That adds the
  following features:
   - When a test sources the file, the file name is printed to the
     result file. This is good because it makes result files easier to
     follow.
   - When a helper file sources a second helper file recursively, then
     the name of the second file is not printed. This is good because
     it would make the result file harder to follow if all the internal
     calls of all helper files were printed.
   - When $rpl_debug is set, all internal calls are printed to the
     result file. This is good because it helps when debugging test
     cases. (With $rpl_debug=1, many of the helper files now print other
     relevant debug info too.)
   - When a file needs to turn off the query log or the warning log
     (disable_query_log/disable_warnings), then the file can tell
     rpl_begin_include_file.inc about it. Then rpl_begin_include_file.inc
     will turn off the log correctly, and rpl_end_include_file.inc
     will turn on the log correctly. Note that if rpl_a.inc sources
     rpl_b.inc and both files need to turn off the log, then the
     log is not turned on when rpl_b.inc ends (because rpl_a.inc
     still needs the log off). This makes it easier to program
     replication helper files.
mysql-test/include/check-testcase.test:
  Made check-testcase ensure that the slave status is reset
  after the test has finished.
mysql-test/include/check_slave_is_running.inc:
  - Use existing framework (check_slave_param.inc) instead of ad-hoc code
    to check value of slave parameters.
  - Use rpl_begin_include_file.inc to improve debug capabilities.
  - improve documentation.
mysql-test/include/check_slave_no_error.inc:
  - Use rpl_begin_include_file.inc to improve debug capabilities.
  - improve documentation.
mysql-test/include/check_slave_param.inc:
  - Use rpl_begin_include_file.inc to improve debug capabilities.
  - improve documentation.
mysql-test/include/cleanup_fake_relay_log.inc:
  - Use RESET SLAVE instead of manual file removal. This also
    resets other replication state.
  - verify that RESET SLAVE correctly removed files.
mysql-test/include/diff_tables.inc:
   - Use rpl_begin_include_file.inc to improve debug capabilities.
   - Improved documentation.
   - file now supports an arbitrary number of tables
     (not just two). The tables are now given as a comma-separated
     list instead of as two variables.
   - You no longer have to specify database name for each table.
     If no database is specified, it defaults to the current
     database.
   - File now restores the connection at the end.
mysql-test/include/end_include_file.inc:
  New file to be sourced at the end of auxiliary replication include
  files. See include/rpl_begin_include_file.inc for details.
mysql-test/include/file_does_not_exist.inc:
  Added .inc file to check that a given file is removed.
mysql-test/include/force_restart.inc:
  Added file to force server restart after test
mysql-test/include/force_restart_if_skipped.inc:
  Added file to force server restart after test, if the test is skipped
mysql-test/include/have_innodb.inc:
  Made have_innodb.inc print sensible message when innodb is
  not supported.
mysql-test/include/io_thd_fault_injection.inc:
  Use rpl_server_restart.inc instead of restart_mysqld.inc in rpl tests
mysql-test/include/kill_query_and_diff_master_slave.inc:
  Renamed diff_master_slave.inc to rpl_diff.inc
mysql-test/include/master-slave.inc:
  - Use new rpl_init.inc file
  - Now, we don't do 'drop table' in master-slave.inc any more. That's good
    because drop table has nothing to do with configuring replication servers.
  - master-slave.inc now supports the additional parameter
    $rpl_server_count. By default, master-slave.inc only
    configures two servers; if $rpl_server_count is set, it
    configures that many servers. Only the second server is
    a slave; the rest are not part of the replication topology.
mysql-test/include/mtr_check.sql:
  Removed unneeded SP (use include/force_restart.inc instead)
mysql-test/include/mysqldump.inc:
  diff_tables.inc now takes only one parameter.
mysql-test/include/ndb_master-slave.inc:
  use master-slave.inc instead of ad-hoc calls to 'connect'
mysql-test/include/ndb_master-slave_2ch.inc:
  use rpl_init.inc instead of ad-hoc setup
mysql-test/include/ndb_not_readonly.inc:
  turn off query log while executing this script.
  this was previously done by the caller. now it's done in the script.
mysql-test/include/report-features.test:
  add newline at end of file
mysql-test/include/reset_master_and_slave.inc:
  rpl_reset.inc replaces this file
mysql-test/include/restart_mysqld.inc:
  force caller to use rpl_restart_server.inc instead if replication is configured
mysql-test/include/rpl_change_topology.inc:
  New file to change replication topology on the fly. This is used
  by rpl_init.inc internally, but is also used by test cases
  that need to change topology (e.g., rpl.rpl_circular_for_4_hosts, which
  reconfigures the topology to make a failover).
mysql-test/include/rpl_connect.inc:
  New file to create a named connection. This file knows about a number
  of "standard" connections (master, slave, server_1, etc), and knows how
  each of them should normally be created. This is mostly used internally
  (e.g., by rpl_init.inc, master-slave.inc, ndb_master-slave_2ch.inc etc),
  but can also be used by tests that need to bring a connection up after
  disconnecting.
mysql-test/include/rpl_connection.inc:
  New file to change connection. This prints the name of the connection.
  However, for files that source rpl_begin_include_file.inc, it does not
  print the name of the connection unless $rpl_debug=1. This is good
  because printing something every time the .inc file changed connection
  would make the result log harder to read.
mysql-test/include/rpl_diff.inc:
   - Made file capable to compare many servers
   - Hence renamed it to rpl_diff.inc
   - If no server list is specified, use all servers from
     server_1 to server_$rpl_server_count
   - It now writes the statement to file before executing it.
     That means it will be subject to SQL string interpolation,
     but not shell string interpolation (which may be
     platform-dependent)
mysql-test/include/rpl_diff_tables.inc:
  Removed this file, since its functionality has been merged into
  diff_tables.inc.
mysql-test/include/rpl_end.inc:
  Renamed master-slave-end.inc to rpl_end.inc, and made it
  work with arbitrary replication topologies (as configured
  with rpl_init.inc and possibly rpl_change_topology.inc). Also
  made it assert that no slave thread has an error. Made it
  assert that no slave thread is stopped, unless
  $rpl_only_running_threads=1.
mysql-test/include/rpl_for_each_slave.inc:
  New test script that executes a command once for each slave.
  This is used by include/rpl_start_slaves.inc and
  include/rpl_stop_slaves.inc and could possibly be useful for other
  custom scripts too.
mysql-test/include/rpl_generate_sync_chain.inc:
  New file that computes the variable $rpl_sync_chain. This variable
  determines in what order slaves are synced by include/rpl_sync.inc.
  The variable is recomputed the first time that include/rpl_sync.inc
  is called after rpl_change_topology.inc.
mysql-test/include/rpl_init.inc:
  Made file work for arbitrary topologies instead of just 4-server
  circle. This file is used by master-slave.inc, rpl_master-slave_2ch.inc
  etc, and also by tests that need other specific replication topologies.
mysql-test/include/rpl_reconnect.inc:
  New auxiliary file that will reconnect many clients to a given
  server. All clients configured by rpl_init.inc will reconnect.
mysql-test/include/rpl_reset.inc:
  Made file work for arbitrary replication topologies,
  check for errors, and sync all threads. Also removed
  'drop table' because that has nothing to do with replication.
mysql-test/include/rpl_restart_server.inc:
  New auxiliary file that restarts a server.
mysql-test/include/rpl_start_server.inc:
  New auxiliary file that starts a server that has been shut down.
mysql-test/include/rpl_start_slaves.inc:
  New auxiliary file to start all slaves configured by rpl_init.inc
  This is used internally by rpl_init.inc but may also be used by tests
  that want to bring all slaves up.
mysql-test/include/rpl_stop_server.inc:
  New auxiliary file that shuts down a server.
mysql-test/include/rpl_stop_slaves.inc:
  New auxiliary file to stop all slaves configured rpl_init.inc. This
  is used internally by rpl_end.inc, but may also be used by tests that
  want to stop all slaves.
mysql-test/include/rpl_sync.inc:
  Made file work for arbitrary replication topologies (as configured
  by rpl_init.inc and possibly rpl_change_topology.inc) instead of
  just 4-server circle.
mysql-test/include/save_master_pos.inc:
  Auxiliary file to save the master position.
mysql-test/include/setup_fake_relay_log.inc:
  - Moved complicated logic to write to file into
    write_var_to_file.inc, so that it can be re-used by
    other tests.
  - Added call to show_rpl_debug_info and die in error case.
mysql-test/include/show_rpl_debug_info.inc:
  - Made file print NOW()
  - Made file print both SHOW MASTER STATUS, SHOW SLAVE HOSTS,
    and SHOW SLAVE STATUS.
  - Made file print debug info for all servers configured by
    rpl_init.inc
mysql-test/include/show_slave_status.inc:
  - Made file use echo instead of SELECT to print variables.
  - Improved comments.
  - Use variable names that are less likely to be used by other tests.
mysql-test/include/start_slave.inc:
  - Made test use rpl_begin_include_file.inc to improve debug
    capabilities.
  - improved documentation
mysql-test/include/stop_slave.inc:
  - Made script capable to detect which threads are running
    and stop only those.
  - Improved documentation
mysql-test/include/stop_slave_io.inc:
  Added file to stop the slave IO thread.
mysql-test/include/stop_slave_sql.inc:
  Added file to stop the slave SQL thread.
mysql-test/include/sync_io_with_master.inc:
  Added file to sync the IO thread of the current connection, up to
  a previously saved position.
mysql-test/include/sync_slave_io_with_master.inc:
  - Made file work with arbitrarily-named connections.
  - Made file use rpl_begin_include_file.inc to improve debug
    capabilities.
mysql-test/include/sync_slave_sql_with_io.inc:
  Added file to sync only the SQL thread, up to the position copied
  in the IO thread.
mysql-test/include/wait_for_query_to_fail.inc:
  Added file to wait for a query to fail.
mysql-test/include/wait_for_slave_io_error.inc:
  - Use rpl_begin_include_file.inc to improve debug capabilities.
  - Use existing atom include/show_slave_status.inc to print error
    message.
  - Improve comments.
  
  ******
   - This file now waits until the slave IO thread has completely
     stopped (to avoid races in tests).
   - Some IO thread errors are non-fatal and don't cause the slave
     IO thread to stop. To allow tests to wait for such errors, we
     add the parameters $slave_io_error_is_nonfatal. If
     $slave_io_error_is_nonfatal is set, this script does not wait
     for the IO thread to stop.
mysql-test/include/wait_for_slave_io_to_start.inc:
  - Made script fail if the IO thread has an error.
  - Use rpl_begin_include_file.inc to improve debug capabilities.
  - Improved documentation.
mysql-test/include/wait_for_slave_io_to_stop.inc:
  - Fail if server is not configured as slave. Previously, the
    script accepted servers not configured as slave because there
    was cleanup code called from master-slave.inc that would execute
    STOP SLAVE on both master and slave. Now all tests have to
    clean up after themselves, so we don't have to call stop slave
    at the beginning of tests. Hence, we disallow calling this
    script on servers not configured as slaves.
  - Use rpl_begin_include_file.inc to improve debug capabilities.
  - Improved documentation.
mysql-test/include/wait_for_slave_param.inc:
  - Added $slave_error_param. This variable can be set to
    Slave_IO_Errno or Slave_SQL_Errno, in which case the
    script fails if the corresponding column in the output from
    SHOW SLAVE STATUS is nonzero.
  - Replaced exit by die.
  - Made it print timeout seconds correctly in error message.
  - Removed $slave_error_message. This is not needed.
  - Use rpl_begin_include_file.inc for better debug capabilities.
mysql-test/include/wait_for_slave_sql_error.inc:
  - Use rpl_begin_include_file.inc for better debug capabilities.
  - Improve documentation
  - Use existing atom show_slave_status.inc to print error.
mysql-test/include/wait_for_slave_sql_error_and_skip.inc:
  - Use rpl_begin_include_file.inc and rpl_connection.inc for better
    debug capabilities.

mysql-test/include/wait_for_slave_sql_to_start.inc:
  - Use rpl_begin_include_file.inc for better debug capabilities.
  - Improve documentation
mysql-test/include/wait_for_slave_sql_to_stop.inc:
  - Fail if Last_SQL_Errno is nonzero.
  - Fail if server is not configured as slave. Previously, the
    script accepted servers not configured as slave because there
    was cleanup code called from master-slave.inc that would execute
    STOP SLAVE on both master and slave. Now all tests have to
    clean up after themselves, so we don't have to call stop slave
    at the beginning of tests. Hence, we disallow calling this
    script on servers not configured as slaves.
  - Use rpl_begin_include_file.inc for better debug capabilities.

mysql-test/include/write_var_to_file.inc:
  Added file to write contents of a mysqltest variable to file.
  (This was previously in setup_fake_relay_log.inc)
mysql-test/mysql-test-run.pl:
  Allow tests to require restart in case the test is skipped.

mysql-test/suite/binlog/t/binlog_drop_if_exists.test:
  Moved test that does not use replication to binlog suite.
mysql-test/suite/binlog/t/binlog_old_versions.test:

mysql-test/suite/binlog/t/binlog_query_filter_rules-master.opt:
  Moved test that does not use replication to binlog suite.
mysql-test/suite/binlog/t/binlog_query_filter_rules.test:
  Moved test that does not use replication to binlog suite.
mysql-test/suite/binlog/t/binlog_server_id.test:
  Moved test that does not use replication to binlog suite.
mysql-test/suite/binlog/t/binlog_sf.test:
  Moved test that does not use replication to binlog suite.
  Since test sets binlog_format internally, it's useless to
  re-run it. Hence we source have_binlog_format_statement.inc
mysql-test/suite/binlog/t/binlog_sql_mode.test:
  - Test does not use replication, so we remove master-slave.inc.
  - mysqltest magically adds --force-if-open to $MYSQL_BINLOG in test
    files that source master-slave.inc. So now we have to add
    --force-if-open explicitly.

mysql-test/suite/rpl/t/rpl_circular_for_4_hosts.test:
  - Use rpl_init.inc instead of circular_rpl_for_4_hosts.inc.
    Connections have been renamed (server_[1234] instead of master_[abcd]),
    we use rpl_sync.inc instead of circular_rpl_for_4_hosts_sync.inc,

    manually, and we use rpl_change_topology.inc instead of manual
    reconfiguration.
  - Added comment to make test understandable.
  - the test contained a race condition. server_4 was not sync'ed. This could
    cause sql_slave_skip_counter to have the value 1 when the test ended, so
    check-testcase would complain. Added 'sync_slave_with_master server_4'.

Post-push fixes:

  - fixed platform dependent result files
  - appeasing valgrind warnings:
   
    Fault injection was also uncovering a previously existing 
    potential mem leaks. For BUG#46166 testing purposes, fixed 
    by forcing handling the leak when injecting faults.

Merging to latest mysql-5.1-bugteam.

"load data infile .."  allowed for access to 
unautohorized tables.
Due to a faulty if-statement it was possible to
circumvent the secure_file_priv restriction.


mysql-test/mysql-test-run.pl:
  * Add SECURE_LOAD_PATH environment variable to mtr test cases.
mysql-test/suite/sys_vars/r/secure_file_priv2.result:

  * fix indentation

IN quantified predicates are never executed directly. They are rather wrapped
inside nodes called IN Optimizers (Item_in_optimizer) which take care of the
execution. However, this is not done during query preparation. Unfortunately
the LIKE predicate pre-evaluates constant right-hand side arguments even
during name resolution. Likely this is meant as an optimization.
      
Fixed by not pre-evaluating LIKE arguments in view prepare mode.

Back-ported to 5.0s

The user-visible problem was that changes to column-level privileges,
happened in between of PREPARE and EXECUTE of a prepared statement, were
neglected. I.e. a prepared statement could be executed with the
column-level privileges as of PREPARE-time. The problem existed for
column-level privileges only.

A similar problem existed for stored programs: the changes between
executions didn't have an effect.

Technically the thing is that table references are cached in
Prepared_statement::prepare() call. In subsequent
Prepared_statement::execute() calls those cached values are used.
There are two functions to get a field by name: find_field_in_table() and
find_field_in_table_ref(). On prepare-phase find_field_in_table_ref() is
called, on execute-phase -- find_field_in_table() because the table is
cached. find_field_in_table() does not check column-level privileges and
expects the caller to do that. The problem was that this check was
forgotten.

The fix is to check them there as it happens in find_field_in_table_ref().

Bug#57913 large negative number to string conversion functions crash
String object which is used as result container of the item
has uninitialized 'str_charset' field. This object
might be used later to preform some internal operations
and str_charset field is involved in these operations.
It leads to crash.
The fix is to intialize str_charset in my_decimal2string() func.

We have several modes when we should disable subquery evaluation.
The reasons for disabling are different. It could be
uselessness of the evaluation as in case of 'CREATE VIEW'
or 'PREPARE stmt', or we should disable subquery evaluation
if tables are not locked yet as it happens in bug#54475, or
too early evaluation of subqueries can lead to wrong result
as it happened in Bug#19077.
Main problem is that if subquery items are treated as const
they are evaluated in ::fix_fields(), ::fix_length_and_dec()
of the parental items as a lot of these methods have
Item::val_...() calls inside.
We have to make subqueries non-const to prevent unnecessary
subquery evaluation. At the moment we have different methods
for this. Here is a list of these modes:

1. PREPARE stmt;
We use UNCACHEABLE_PREPARE flag.
It is set during parsing in sql_parse.cc, mysql_new_select() for
each SELECT_LEX object and cleared at the end of PREPARE in
sql_prepare.cc, init_stmt_after_parse(). If this flag is set
subquery becomes non-const and evaluation does not happen.

2. CREATE|ALTER VIEW, SHOW CREATE VIEW, I_S tables which
   process FRM files
We use LEX::view_prepare_mode field. We set it before
view preparation and check this flag in
::fix_fields(), ::fix_length_and_dec().
Some bugs are fixed using this approach,
some are not(Bug#57352, Bug#57703). The problem here is
that we have a lot of ::fix_fields(), ::fix_length_and_dec()
where we use Item::val_...() calls for const items.

3. Derived tables with subquery = wrong result(Bug19077)
The reason of this bug is too early subquery evaluation.
It was fixed by adding Item::with_subselect field
The check of this field in appropriate places prevents
const item evaluation if the item have subquery.
The fix for Bug19077 fixes only the problem with
convert_constant_item() function and does not cover
other places(::fix_fields(), ::fix_length_and_dec() again)
where subqueries could be evaluated.

Example:
CREATE TABLE t1 (i INT, j BIGINT);
INSERT INTO t1 VALUES (1, 2), (2, 2), (3, 2);
SELECT * FROM (SELECT MIN(i) FROM t1
WHERE j = SUBSTRING('12', (SELECT * FROM (SELECT MIN(j) FROM t1) t2))) t3;
DROP TABLE t1;

4. Derived tables with subquery where subquery
   is evaluated before table locking(Bug#54475, Bug#52157)

Suggested solution is following:

-Introduce new field LEX::context_analysis_only with the following
 possible flags:
 #define CONTEXT_ANALYSIS_ONLY_PREPARE 1
 #define CONTEXT_ANALYSIS_ONLY_VIEW    2
 #define CONTEXT_ANALYSIS_ONLY_DERIVED 4
-Set/clean these flags when we perform
 context analysis operation
-Item_subselect::const_item() returns
 result depending on LEX::context_analysis_only.
 If context_analysis_only is set then we return
 FALSE that means that subquery is non-const.
 As all subquery types are wrapped by Item_subselect
 it allow as to make subquery non-const when
 it's necessary.

On this platform we seem to get lots of other signals
while waiting for SIGKILL to be delivered.

Solution: use sigsuspend(<all signals blocked>)



dbug/dbug.c:
  New function _db_suicide_() which does kill(myself, -9) and then waits forever.
include/my_dbug.h:
  Let DBUG_SUICE wait forever until the KILL signal is delivered, and process dies.
