When statement to be prepared contained CREATE PROCEDURE, CREATE FUNCTION
or CREATE TRIGGER statements with a syntax error in it, the preparation
would fail with syntax error message, but the memory could be corrupted.

The problem occurred because we switch memroot when parse stored
routine or trigger definitions, and on parse error we restored the
original memroot only after performing some memory operations.  In more
detail:
 - prepared statement would activate its own memory root to parse
   the definition of the stored procedure.
 - SP would reset this memory root with its own memory root to
   parse SP statements
 - a syntax error would happen
 - prepared statement would restore the original memory root
 - stored procedure would restore what it thinks was the original
   memory root, but actually was the statement memory root.
That led to double free - in destruction of the statement and in
a next call to mysql_parse().

The solution is to restore memroot right after the failed parsing.

  The change here is for safety, currently query_cache_abort() and
  lex->unit.cleanup() calls do not use current memroot.

The problem was that during statement re-execution if the result was
empty the old result could be returned for group functions.

The solution is to implement proper cleanup() method in group
functions.

Re-execution of a parametrized prepared statement or a stored routine
with a SELECT that use LEFT JOIN with second table having only one row
could yield incorrect result.

The problem appeared only for left joins with second table having only
one row (aka const table) and equation conditions in ON or WHERE clauses
that depend on the argument passed.  Once the condition was false for
second const table, a NULL row was created for it, and any field involved
got NULL-value flag, which then was never reset.

The cause of the problem was that Item_field::null_value could be set
without being reset for re-execution.  The solution is to reset
Item_field::null_value in Item_field::cleanup().

subquery resulted in the creation of a andor structure

should work in Prepared Statements. Post-review changeset.

Problem: There are some commands which are avaiable to be executed in SP
         but cannot be prepared. This patch fixes this and makes it possible
         prepare these statements.

Changes: The commands later are made available in PS. RESET has been forbidden
         in SF/Trigger.

Solution: All current server commands where checked and those missing (see later)
          we added. Tests for all of the commands with repeated executions were
          added - testing with SP, SF and PS.

dropping/creating tables".

The bug could lead to a crash when multi-delete statements were
prepared and used with temporary tables.

The bug was caused by lack of clean-up of multi-delete tables before
re-execution of a prepared statement. In a statement like
DELETE t1 FROM t1, t2 WHERE ... the first table list (t1) is
moved to lex->auxilliary_table_list and excluded from lex->query_tables
or select_lex->tables. Thus it was unaccessible to reinit_stmt_before_use
and not cleaned up before re-execution of a prepared statement.

  auxilliary_table_list is not NULL and clean it up if the check returns
  a true value.
sql/sql_prepare.cc:
  Move the one table clean-up functionality to a method of st_table_list.
  Clean up auxiliary_table_list if it's not empty.

 Bug#19022 "Memory bug when switching db during trigger execution"
 Bug#17199 "Problem when view calls function from another database."
 Bug#18444 "Fully qualified stored function names don't work correctly in
            SELECT statements"

 Documentation note: this patch introduces a change in behaviour of prepared
 statements.

 This patch adds a few new invariants with regard to how THD::db should
 be used. These invariants should be preserved in future:

  - one should never refer to THD::db by pointer and always make a deep copy
    (strmake, strdup)
  - one should never compare two databases by pointer, but use strncmp or
    my_strncasecmp
  - TABLE_LIST object table->db should be always initialized in the parser or
    by creator of the object.

    For prepared statements it means that if the current database is changed
    after a statement is prepared, the database that was current at prepare
    remains active. This also means that you can not prepare a statement that
    implicitly refers to the current database if the latter is not set.
    This is not documented, and therefore needs documentation. This is NOT a
    change in behavior for almost all SQL statements except:
     - ALTER TABLE t1 RENAME t2 
     - OPTIMIZE TABLE t1
     - ANALYZE TABLE t1
     - TRUNCATE TABLE t1 --
     until this patch t1 or t2 could be evaluated at the first execution of
     prepared statement. 

     CURRENT_DATABASE() still works OK and is evaluated at every execution
     of prepared statement.

     Note, that in stored routines this is not an issue as the default
     database is the database of the stored procedure and "use" statement
     is prohibited in stored routines.

  This patch makes obsolete the use of check_db_used (it was never used in the
  old code too) and all other places that check for table->db and assign it
  from THD::db if it's NULL, except the parser.

 How this patch was created: THD::{db,db_length} were replaced with a
 LEX_STRING, THD::db. All the places that refer to THD::{db,db_length} were
 manually checked and:
  - if the place uses thd->db by pointer, it was fixed to make a deep copy
  - if a place compared two db pointers, it was fixed to compare them by value
    (via strcmp/my_strcasecmp, whatever was approproate)
 Then this intermediate patch was used to write a smaller patch that does the
 same thing but without a rename.

 TODO in 5.1:
   - remove check_db_used
   - deploy THD::set_db in mysql_change_db

too many open statements". The patch adds a new global variable
@@max_prepared_stmt_count. This variable limits the total number
of prepared statements in the server. The default value of
@@max_prepared_stmt_count is 16382. 16382 small statements
(a select against 3 tables with GROUP, ORDER and LIMIT) consume 
100MB of RAM. Once this limit has been reached, the server will 
refuse to prepare a new statement and return ER_UNKNOWN_ERROR 
(unfortunately, we can't add new errors to 4.1 without breaking 5.0). The limit is changeable after startup
and can accept any value from 0 to 1 million. In case
the new value of the limit is less than the current
statement count, no new statements can be added, while the old
still can be used. Additionally, the current count of prepared 
statements is now available through a global read-only variable 
@@prepared_stmt_count.

 of system vars at PREPARE time": implement a special Item
to handle system variables. This item substitutes itself with 
a basic constant containing variable value at fix_fields.


mysql-test/r/ps.result:
  - test results fixed (Bug#9359).
mysql-test/t/ps.test:
  - add a test case for Bug#9359 "Prepared statements take snapshot
   of system vars at PREPARE time"
sql/item_func.cc:
  - implement Item_func_get_system_var: we should not evaluate system
  variables in the parser, but instead should create an item which 
  is evaluated to a constant at execute.
  - remove an unused function
sql/item_func.h:
  Add a new item, Item_func_get_system_var
sql/mysql_priv.h:
  Move necessary declarations to make set_var.h objects visible in 
  item_func.h
sql/set_var.cc:
  - we should not print to network from get_system_var: if it's called
  from prepared statement prepare, we get packets out of order when using
  the binary protocol. Instead report the error to be sent to the user later.
  This is a backport from 5.0.
sql/set_var.h:
  - declaration of enum_var_type moved to mysql_priv.h

mysql-test/t/ps.test:
  Disable prepared statements for a part of the test to avoid
  result mismatch.

 syntax in binlog which stops replication":
disallow the use of parameter markers which can lead to generation
of malformed binlog queries. 


mysql-test/r/ps.result:
  Test results fixed: a test case for Bug#11299
mysql-test/t/ps.test:
  A test case for Bug#11299
sql/sql_lex.cc:
  Introduce a new parser token for a parameter marker. Make sure
  that a parameter marker can not be used in a query which, when
  transformed to a binlog query, becomes grammatically incorrect.
sql/sql_yacc.yy:
  The check for COM_PREPARE has been moved into the lexer.
mysql-test/var:
  New BitKeeper file ``mysql-test/var''

character set is UCS2".
The bug is no longer repeatable.


mysql-test/r/ps.result:
  Test results fixed (a test case for Bug#9442)
mysql-test/t/ps.test:
  A test case for Bug#9442 "Set parameter make query fail if column 
  character set is UCS2

binary).


mysql-test/r/ps.result:
  Test results fixed (Bug#9379)
mysql-test/t/ps.test:
  A test case for Bug#9379 (collation of a parameter marker is binary)
sql/item.cc:
  - set Item_param::collation to str_value collation, if Item_param
  is assigned a string. Reset it to default in Item_param::reset() (on 
  the next execution it can be assigned a number).
sql/item_func.cc:
  - now that item collation can change between executions
  (if this item is Item_param), we need to register the change
  of the execution tree in the rollback list.

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.


mysql-test/r/ps.result:
  Bug#11458: test results fixed
mysql-test/t/ps.test:
  - add a test case for Bug#11458 "Prepared statement with subselects return 
  random data"
sql/item.cc:
  - remove unnecessary Item_param::fix_fields
  - fix Item_param::set_null to set item_type accordingly (safety:
    Item_param should behave like a basic constant).
sql/item.h:
  Remove Item_param::fix_fields
sql/item_subselect.h:
  Remove no more existing friend.
sql/mysql_priv.h:
  Add UNCACHEABLE_PREPARE to mark all subqueries as uncacheable if
  in statement prepare (backport from 5.0).
sql/sql_lex.h:
  Comment fixed.
sql/sql_parse.cc:
  If in statement prepare, mark all subqueries as uncacheable (backport
  from 5.0)
sql/sql_prepare.cc:
  Switch off the uncacheable flag from all subqueries after statement
  prepare is done (backport from 5.0)

INSERT ... SELECT with UNION" (reviewed version).

Altough bug manifest itself only starting from 5.0 it is better to
apply fix to 4.1 to keep some assumptions true and make code more
future-proof.


mysql-test/r/ps.result:
  Added test case for bug #11060 "Server crashes on re-execution of
  prepared INSERT ... SELECT with UNION".
mysql-test/t/ps.test:
  Added test case for bug #11060 "Server crashes on re-execution of
  prepared INSERT ... SELECT with UNION".
sql/sql_insert.cc:
  select_insert::prepare():
    Item::fix_fields() methods operate assuming that LEX::current_select
    points to the select to which current item belongs. Thus
    during check_insert_fields() routine execution LEX::current_select
    should point ot the first select in query since this is the
    select with which items in insert list is associated.
    But if we have INSERT SELECT UNION SELECT type of query
    LEX::current_select will point to the fake_select_lex instead
    since select_insert::prepare() is called during processing of JOIN
    which corresponds to this select_lex.
    So we have set LEX::current_select before calling check_insert_fields()
    and restore it afterwards.

 - Print warning that says display width is not supported for datatype TIMESTAMP, if user tries to create a TIMESTAMP column with display width.
 - Use display width for TIMESTAMP only in type_timestamp test to make sure warning is displayed correctly.


mysql-test/include/ps_create.inc:
  Reove all uses of display width in for TIMESTAMP columns, except in the type_timestamp test.
mysql-test/r/alias.result:

 error for LIMIT placeholder".
The patch adds grammar support for LIMIT ?, ? and changes the
type of ST_SELECT_LEX::select_limit,offset_limit from ha_rows to Item*,
so that it can point to Item_param.


mysql-test/include/ps_modify.inc:
  Fix existing tests: now LIMIT can contain placeholders.
mysql-test/include/ps_query.inc:
  Fix existing tests: now LIMIT can contain placeholders.
mysql-test/r/ps.result:
  Add basic test coverage for LIMIT ?, ? and fix test results.
mysql-test/r/ps_2myisam.result:
  Fix test results: now LIMIT can contain placeholders.
mysql-test/r/ps_3innodb.result:
  Fix test results: now LIMIT can contain placeholders.
mysql-test/r/ps_4heap.result:
  Fix test results: now LIMIT can contain placeholders.
mysql-test/r/ps_5merge.result:
  Fix test results: now LIMIT can contain placeholders.
mysql-test/r/ps_6bdb.result:
  Fix test results: now LIMIT can contain placeholders.
mysql-test/r/ps_7ndb.result:
  Fix test results: now LIMIT can contain placeholders.
mysql-test/t/ps.test:
  Add basic test coverage for LIMIT ?, ?.
sql/item.h:
  Add a short-cut for (ulonglong) val_int() to Item.
  Add a constructor to Item_int() that accepts ulonglong.
  Simplify Item_uint constructor by using the c-tor above.
sql/item_subselect.cc:
  Now select_limit has type Item *.
  We can safely create an Item in Item_exists_subselect::fix_length_and_dec():
  it will be allocated in runtime memory root and freed in the end of
  execution.
sql/sp_head.cc:
  Add a special initalization state for stored procedures to 
  be able to easily distinguish the first execution of a stored procedure
  from prepared statement prepare.
sql/sql_class.h:
  Introduce new state 'INITIALIZED_FOR_SP' to be able to easily distinguish
  the first execution of a stored procedure from prepared statement prepare.
sql/sql_derived.cc:
  - use unit->set_limit() to set unit->select_limit_cnt, offset_limit_cnt
    evreryplace. Add a warning about use of set_limit in 
  mysql_derived_filling.
sql/sql_error.cc:
  - use unit->set_limit() to set unit->select_limit_cnt, offset_limit_cnt
    evreryplace.
  - this change is also aware of bug#11095 "show warnings limit 0 returns 
  all rows instead of zero rows", so the one who merges the bugfix from
  4.1 can use local version of sql_error.cc.
sql/sql_handler.cc:
  - use unit->set_limit() to initalize 
  unit->select_limit_cnt,offset_limit_cnt everyplace.
sql/sql_lex.cc:
  Now ST_SELECT_LEX::select_limit, offset_limit have type Item *
sql/sql_lex.h:
  Now ST_SELECT_LEX::select_limit, offset_limit have type Item *
sql/sql_parse.cc:
  - use unit->set_limit() to initalize 
  unit->select_limit_cnt,offset_limit_cnt everyplace. 
  - we can create an Item_int to set global limit of a statement:
  it will be created in the runtime mem root and freed in the end of
  execution.
sql/sql_repl.cc:
  Use unit->set_limit to initialize limits.
sql/sql_select.cc:
  - select_limit is now Item* so the proper way to check for default value
  is to compare it with NULL.
sql/sql_union.cc:
  Evaluate offset_limit_cnt using the new type of ST_SELECT_LEX::offset_limit
sql/sql_view.cc:
  Now ST_SELECT_LEX::select_limit, offset_limit have type Item *
sql/sql_yacc.yy:
  Add grammar support for LIMIT ?, ? clause.
