data": remove the fix for another bug (8807) that
added OUTER_REF_TABLE_BIT to all subqueries that used a placeholder
to prevent their evaluation at prepare. As this bit hanged in
Item_subselect::used_tables_cache for ever, a constant subquery with
a placeholder was never evaluated as such, which caused wrong
choice of the execution plan for the statement.
- to fix Bug#8807 backport a better fix from 5.0
- post-review fixes.

Bug#8367 "low log doesn't gives complete information about prepared
statements"
Implement status variables for prepared statements commands (a port of
the patch by Andrey Hristov).
See details in comments to the changed files.
No test case as there is no way to test slow log/general log in
mysqltest.
mysql-test/r/ps_grant.result:
Now execute is logged with tag 'Execute' (changed result file).
sql/mysql_priv.h:
- remove obsolete macro.
- add declarations for new status variables.
- export function log_slow_statement, which now is used in sql_prepare.cc
sql/mysqld.cc:
Add status variables for prepared statements API: now we record
mysql_stmt_close, mysql_stmt_reset, mysql_stmt_prepare, mysql_stmt_execute
mysql_stmt_send_long_data, PREPARE, EXECUTE, DEALLOCATE.
sql/sql_parse.cc:
- account DEALLOCATE prepare as a Com_stmt_close command (close of a
prepared statement).
sql/sql_prepare.cc:
- fix a bug in SQL syntax for prepared statements + logging:
if we use --log and EXECUTE stmt USING @no_such_variable;, the
server crashed because the old code assumed that the variable
returned by get_var_with_binlog is never NULL.
- account statistics for
mysql_stmt_{prepare,execute,close,reset,send_long_data} in
Com_stmt_{prepare,execute,close,reset,send_long_data} correspondingly.
- log slow statements into the slow log early, when thd->query
points to a valid (with expanded placeholder values) query.
The previous version was logging it in sql_parse, when thd->query
is empty. Prevent the server from logging the statement twice by
setting thd->enable_slow_log= FALSE.
- now in case of EXECUTE stmt in SQL syntax for prepared statements the
general log gets two queries, e.g.
Query EXECUTE stmt USING @a, @b, @c
Execute INSERT INTO t1 VALUES (1, 2, 3)
This makes the behavior consistent with PREPARE command, which
also logs the statement twice.
ALTER, OPTIMIZE and ANALYZE statements".
In 4.1 we disabled logging of slow admin statements. The fix adds an
option to enable it back.
No test case (slow log is not tested in the test suite), but tested
manually.
+ post-review fixes (word police mainly).
sql/mysql_priv.h:
- declaration for a new option
sql/mysqld.cc:
Add server option '--log-slow-admin-statements' to log slow
optimize/alter/etc statements to the slow log if it's enabled.
Add warnings that this option works only if the slow log is open.
sql/sql_class.h:
Rename 'thd->slow_command' to thd->enable_slow_log (negates
the meaning of this variable, and so resolves the need to negate
value opt_log_slow_admin_statements when setting it).
sql/sql_parse.cc:
Implement optional logging of administrative statements in the slow log.

1.) Added a new option to mysql_lock_tables() for ignoring FLUSH TABLES.
Used the new option in create_table_from_items().
It is necessary to prevent the SELECT table from being reopend.
It would get new storage assigned for its fields, while the
SELECT part of the command would still use the old (freed) storage.
2.) Protected the CREATE TABLE and CREATE TABLE ... SELECT commands
against a global read lock. This prevents a deadlock in
CREATE TABLE ... SELECT in conjunction with FLUSH TABLES WITH READ LOCK
and avoids the creation of new tables during a global read lock.
3.) Replaced set_protect_against_global_read_lock() and
unset_protect_against_global_read_lock() by
wait_if_global_read_lock() and start_waiting_global_read_lock()
in the INSERT DELAYED handling.

vio/viosocket.c:
Added function comment
and fixing it another way (per Monty; a simpler solution which does not increase the number
of binlog events is to always execute DROP TEMPORARY TABLE IF EXISTS on slave). A new test rpl_drop_temp.
2) fixing BUG#8436 "Multiple "stacked" SQL statements cause replication to stop" by setting
thd->query_length to the length of the query being executed, not counting the next queries
if this is a multi-query. Should also improve display of SHOW PROCESSLIST. A new test rpl_multi_query.
mysql-test/r/drop_temp_table.result:
back to one single DROP
sql/sql_base.cc:
undoing the fix I had made some days ago: we are back to one single DROP TEMPORARY TABLE for all temp tables.
sql/sql_parse.cc:
1) set thd->query_length to the length of the query being executed, excluding the other next queries
if this is a multi-query. The setting happens ASAP, ie. just after we know it's a multi-query, ie. just after yyparse().
Don't include the ';' in thd->query_length, because this is not good for storage in binlog.
2) always execute a DROP TEMPORARY TABLE IF EXISTS on slave, don't skip it even if --replicate-ignore-table
connections is actually reset after an hour, and also fix (unlikely)
conditions under which the per-hour query and connection limits could be
exceeded. (Bug #8350)
sql/sql_parse.cc:
Add time_out_user_resource_limits() function to
reset the user resource limits before they are
checked, and add locking to check_mqh() because
not doing so isn't as safe as the old comment
explaining its absence said it is.
