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().

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.
mysql-test/r/ps.result:

dropping/creating tables": test that multi-delete
tables are cleaned up properly before re-execution.
sql/sql_lex.cc:
Always initialize auxilliary_table_list when we initialize the lex:
this way we don't have to check that lex->sql_command equals to
SQLCOM_DELETE_MULTI whenever we need to access auxilliary_table_list.
In particular, in reinit_stmt_before_use we can simply check that
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

sql/item_strfunc.cc:

sql/slave.cc:
While we are at it, replace direct access to thd->db with a method.

sql/slave.h:

sql/sp.cc:
Rewrite sp_use_new_db: this is a cleanup that I needed in order to understand
this function and ensure that it has no bugs.
sql/sp.h:
Add a new declaration for sp_use_new_db (uses LEX_STRINGs) and a comment.
sql/sp_head.cc:
- drop sp_name_current_db_new - a creator of sp_name class that was used
when sp_name was created for an identifier without an explicitly initialized
database. Now we pass thd->db to constructor of sp_name right in the
parser.
- rewrite sp_head::init_strings: name->m_db is always set now
- use the new variant of sp_use_new_db
- we don't need to update thd->db with SP MEM_ROOT pointer anymore when
parsing a stored procedure, as noone will refer to it (yes!)
sql/sp_head.h:
- remove unneded methods and members
sql/sql_class.h:
- introduce 3 THD methods to work with THD::db:
.set_db to assign the current database
.reset_db to reset the current database (temporarily) or set it to NULL
.opt_copy_db_to - to deep-copy thd->db to a pointer if it's not NULL
sql/sql_db.cc:
While we are at it, replace direct access to thd->db with a method.
Should simplify future conversion of THD::db to LEX_STRING.
sql/sql_insert.cc:
- replace checks with asserts: table_list->db must be always set in the parser.
sql/sql_lex.h:
- add a comment
sql/sql_parse.cc:
- implement the invariant described in the changeset comment.
- remove juggling with lex->sphead in SQLCOM_CREATE_PROCEDURE:
now db_load_routine uses its own LEX object and doesn't damage the main
LEX.
- add DBUG_ASSERT(0) to unused "check_db_used"
sql/sql_table.cc:
- replace a check with an assert (table_ident->db)
sql/sql_trigger.cc:
While we are at it, replace direct access to thd->db with a method.
Should simplify future conversion of THD::db to LEX_STRING.
sql/sql_udf.cc:
- use thd->set_db instead of direct modification of to thd->db
sql/sql_view.cc:
- replace a check with an assert (view->db)
sql/sql_yacc.yy:
- make sure that we always copy table->db or name->db or ident->db or
select_lex->db from thd->db if the former is not set. If thd->db
is not set but is accessed, return an error.
sql/tztime.cc:
- be nice, never copy thd->db by pointer.

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.

the set_var/sys_var class design. Updates are, however, protected

sql/item_row.cc:
Implement Item_row::cleanup(): we should reset used_tables_cache
before reexecution of a prepared statement. In case ROW
arguments contain a placeholder, used_tables_cache has PARAM_TABLE
bit set in statement prepare. As a result, when executing a statement,
the condition push down algorithm (make_cond_for_table) would think
that the WHERE clause belongs to the non-existent PARAM_TABLE and
wouldn't attach the WHERE clause to any of the real tables,
effectively optimizing the clause away.
