The patch for Bug#21074 replaces acquisition of the global LOCK_open lock
with exclusive locks on table names in such operations ad DROP TABLE
and RENAME TABLE.
Unfortunately, NDB internally assumes that LOCK_open is acquired and
tries to release it.
This dependency should be fixed by a separate (and significant in size)
patch. For now we just satisfy it - after all, the original
goal of the patch for Bug#21074 was to move query_cache_invalidate
outside of the scope of LOCK_open, and we still can do that.
This fixes some failing NDB tests in the runtime tree.

Move release of LOCK_open after ha_ndbcluster::rename_tables to
satisfy an assert in ndb_log_schema_op.

When executing a CREATE EVENT statement with ON COMPLETION NOT PRESERVE
clause (explicit or implicit) and completion date in the past, we do not
create the event. Or, put it differently, we create it and then drop
immediately.
A warning is issued in this case, not an error -- we want to load
successfully old database dumps, and such dumps may contain events
that are no longer valid.

we now have exclusive name lock on the table name in mysql_rm_table_part2,
we still should keep LOCK_open - some storage engines are not

moved out of LOCK_open scope.

incomplete in 5.0 (and review fixes).
When in 5.0.13 I introduced class Prepared_statement and methods
::prepare and ::execute, general logging was left out of this class.
This was good for stored procedures, since in stored procedures
we do not log sub-statements, but introduced a regression in case of SQL
syntax for prepared statements, as previously we would log the actual
statements to the log, and after the change we would log only
COM_QUERY text.
Restore the old behavior, but still suppress logging if inside a stored
procedure.
Based on a community contributed patch from Vladimir Shebordaev.
No test case since we do not have a mechanism to test output
of the general log.

causes full table lock on innodb table.
Also fixes Bug#28502 Triggers that update another innodb table
will block on X lock unnecessarily (duplciate).
Code review fixes.
Both bugs' synopses are misleading: InnoDB table is
not X locked. The statements, however, cannot proceed concurrently,
but this happens due to lock conflicts for tables used in triggers,
not for the InnoDB table.
If a user had an InnoDB table, and two triggers, AFTER UPDATE and
AFTER INSERT, competing for different resources (e.g. two distinct
MyISAM tables), then these two triggers would not be able to execute
concurrently. Moreover, INSERTS/UPDATES of the InnoDB table would
not be able to run concurrently.
The problem had other side-effects (see respective bug reports).
This behavior was a consequence of a shortcoming of the pre-locking
algorithm, which would not distinguish between different DML operations
(e.g. INSERT and DELETE) and pre-lock all the tables
that are used by any trigger defined on the subject table.
The idea of the fix is to extend the pre-locking algorithm to keep track,
for each table, what DML operation it is used for and not
load triggers that are known to never be fired.

sql/item.h:
enum trg_event_type is needed in table.h
sql/sp.cc:
Take into account table_list->trg_event_map when determining
what tables to pre-lock.
After this change, if we attempt to fire a
trigger for which we had not pre-locked any tables, error
'Table was not locked with LOCK TABLES' will be printed.
This, however, should never happen, provided the pre-locking
algorithm has no programming bugs.
Previously a trigger key in the sroutines hash was based on the name
of the table the trigger belongs to. This was possible because we would
always add to the pre-locking list all the triggers defined for a table when
handling this table.
Now the key is based on the name of the trigger, owing
to the fact that a trigger name must be unique in the database it
belongs to.
sql/sp_head.cc:
Generate sroutines hash key in init_spname(). This is a convenient
place since there we have all the necessary information and can
avoid an extra alloc.
Maintain and merge trg_event_map when adding and merging elements
of the pre-locking list.
sql/sp_head.h:
Add ,m_sroutines_key member, used when inserting the sphead for a
trigger into the cache of routines used by a statement.
Previously the key was based on the table name the trigger belonged
to, since for a given table we would add to the sroutines list
all the triggers defined on it.
sql/sql_lex.cc:
Introduce a new lex step: set_trg_event_type_for_tables().
It is called when we have finished parsing but before opening
and locking tables. Now this step is used to evaluate for each
TABLE_LIST instance which INSERT/UPDATE/DELETE operation, if any,
it is used in.
In future this method could be extended to aggregate other information
that is hard to aggregate during parsing.
sql/sql_lex.h:
Add declaration for set_trg_event_type_for_tables().
sql/sql_parse.cc:
Call set_trg_event_type_for_tables() after MYSQLparse(). Remove tabs.

sql/sql_yacc.yy:
Move assignment of sp_head::m_type before calling sp_head::init_spname(),
one is now used inside another.
sql/table.cc:
Implement TABLE_LIST::set_trg_event_map() - a method that calculates
wh triggers may be fired on this table when executing a statement.
sql/table.h:
Add missing declarations.
Move declaration of trg_event_type from item.h (it will be needed for
trg_event_map bitmap when we start using Bitmap template instead
of uint8).

A race condition in the integration between MyISAM and the query cache code
caused the query cache to fail to invalidate itself on concurrently inserted
data.
This patch fix this problem by using the existing handler interface which, upon
each statement cache attempt, compare the size of the table as viewed from the
cache writing thread and with any snap shot of the global table state. If the
two sizes are different the global table size is unknown and the current
statement can't be cached.

SHOW CREATE TABLE or SELECT FROM I_S.
This is the last patch for this bug, which depends on the big
CS patch and was pending.
The problem was that SHOW CREATE statements returned original
queries in the binary character set. That could cause the query
to be unreadable.
The fix is to use original character_set_client when sending
the original query to the client. In order to preserve the query
in mysqldump, 'binary' character set results should be set when
issuing SHOW CREATE statement. If either source or destination
character set is 'binary' , no conversion is performed.
The idea is that since the source character set is no longer
'binary', we fix the destination character set to still produce
valid dumps.

Switch character_set_results of mysqldump-connection before
calling SHOW CREATE statements for the objects.
