ESCAPE has length of 1 if specified and sql_mode is NO_BACKSLASH_ESCAPES
or has length of 0 or 1 in every other situation.

mysql-test/r/select.result:
results of test for bug 12595
mysql-test/t/select.test:
test for bug #12595 (ESCAPE must be exactly one character long)
sql/item_cmpfunc.cc:
if ESCAPE was in the statement check whether its length is
different than 1. In NO_BACKSLASH_ESCAPES mode only length of 1 is
allowed, otherwise the length could be 0 or 1 character (code point
in the sense of Unicode).
sql/item_cmpfunc.h:
pass variable from the parsing stage - whether
ESCAPE clause was found in the statement
sql/sql_help.cc:
pass FALSE for escape_used_in_parsing because we
want the default mode of no error checking - our internal code.

initialized variable used to transfer information during
parsing up in the stack when reducing in the grammar
sql/sql_lex.h:
new variable used for transfering information when

sql/sql_yacc.yy:
initialize Lex->escape_used and then use it when reducing.
This is needed as fix for bug #12595 to distinguish between
situation where ESCAPE was found and when not because internally
we may pass a string an empty string and there is no other way
to find out whether this is correct or not in case of
NO_BACKSLASH_ESCAPES mode, which allows only length of 1 if
ESCAPE is part of the SQL statement.

The bug was in JOIN::join_free which was wrongly determining that
all joins have been already executed and therefore all used tables
can be closed.
mysql-test/r/subselect_innodb.result:
- test results fixed (Bug#12736 "Server crash during a select
mysql-test/t/subselect_innodb.test:
- a test case for Bug#12736 "Server crash during a select": test
that ha_index_or_rnd_end and mysql_unlock_tables are called
for all used tables in proper order.
sql/item_subselect.cc:
- implement subselect_union_engine::is_executed
sql/item_subselect.h:
- implement Item_subselect::is_evaluated. This function is used
to check whether we can clean up a non-correlated join of a subquery
when cleaning up the join of the outer query
sql/sql_lex.h:
- declare st_select_lex::cleanup_all_joins
sql/sql_select.cc:
- remove an argument from JOIN::join_free, it's now not used
- reimplement JOIN::join_free to not unlock tables if there
is a subquery that has not yet been evaluated. Make sure that the
new implementation calls ha_index_or_rnd_end for every table in
the join and inner joins, because all table cursors must be closed
before mysql_unlock_tables.
sql/sql_select.h:
- JOIN::join_free signature changed
sql/sql_union.cc:
- implement a helper method st_select_lex::cleanup_all_joins, which
recursively walks over a tree of joins and calls cleanup() for
each join.

cursor is interpreted latin1 character and Bug#9819 "Cursors: Mysql Server
Crash while fetching from table with 5 million records."
A fix for a possible memory leak when fetching into an SP cursor
in a long loop.
The patch uses a common implementation of cursors in the binary protocol and
in stored procedures and implements materialized cursors.
For implementation details, see comments in sql_cursor.cc
include/my_sys.h:
- declaration for multi_alloc_root
libmysqld/Makefile.am:
- drop protocol_cursor.cc, add sql_cursor.cc (replaces the old
implementation of cursors with a new one)
mysql-test/r/ctype_ujis.result:
- test results fixed (a test case for Bug#6513)
mysql-test/r/sp-big.result:
- test results fixed (a test case for Bug#9819)
mysql-test/t/ctype_ujis.test:
Add a test case for Bug#6513 "Test Suite: Values inserted by using cursor is
interpreted latin1 character"
mysql-test/t/sp-big.test:
Add a restricted test case for Bug#9819 "Cursors: Mysql Server Crash
while fetching from table with 5 million records."
mysys/my_alloc.c:
- an implementation of multi_alloc_root; this is largely a copy-paste
from mulalloc.c, but the function is small and there is no easy way
to reuse the existing C function.
sql/Makefile.am:
- add sql_cursor.h, sql_cursor.cc (a new implementation of stored procedure
cursors) and drop protocol_cursor.cc (the old one)
sql/handler.cc:
- now TABLE object has its mem_root always initialized.
Adjust the implementation handler::ha_open
sql/item_subselect.cc:
- adjust to the changed declaration of st_select_lex_unit::prepare
sql/protocol.h:
- drop Protocol_cursor
sql/sp_head.cc:
- move juggling with Query_arena::free_list and Item::next to
sp_eval_func_item, as this is needed in 3 places already.
sql/sp_head.h:
- declare a no-op implementation for cleanup_stmt in sp_instr_cpush.
This method is needed for non-materializing cursors, which are yet not
used in stored procedures.
- declaration for sp_eval_func_item
sql/sp_rcontext.cc:
- reimplement sp_cursor using the new implementation of server side cursors.
- use sp_eval_func_item to assign values of SP variables from the
row fetched from a cursor. This should fix a possible memory leak in
the old implementation of sp_cursor::fetch
sql/sp_rcontext.h:
- reimplement sp_cursor using the new implementation of server side cursors.
sql/sql_class.cc:
- disable the functionality that closes transient cursors at commit/rollback;
transient cursors are not used in 5.0, instead we use materialized ones.
To be enabled in a later version.
sql/sql_class.h:
- adjust to the rename Cursor -> Server_side_cursor
- additional declarations of select_union used in materialized cursors
sql/sql_derived.cc:
- reuse bits of tmp table code in UNION, derived tables, and materialized
cursors
- cleanup comments
sql/sql_lex.h:
- declarations of auxiliary methods used by materialized cursors
- a cleanup in st_select_lex_unit interface
sql/sql_list.h:
- add an array operator new[] to class Sql_alloc
sql/sql_prepare.cc:
- split the tight coupling of cursors and prepared statements to reuse
the same implementation in stored procedures
- cleanups of error processing in Prepared_statement::{prepare,execute}
sql/sql_select.cc:
- move the implementation of sensitive (non-materializing) cursors to
sql_cursor.cc
- make temporary tables self-contained: the table, its record and fields
are allocated in TABLE::mem_root. This implementation is not clean
and resets thd->mem_root several times because of the way create_tmp_table
works (many additional things are done inside it).
- adjust to the changed declaration of st_select_lex_unit::prepare
sql/sql_select.h:
- move the declaration of sensitive (non-materializing) cursors to
sql_cursor.cc
sql/sql_union.cc:
- move pieces of st_select_unit::prepare to select_union and st_table
methods to be able to reuse code in the implementation of materialized
cursors
sql/sql_view.cc:
- adjust to the changed signature of st_select_lex_unit::prepare
sql/table.cc:
- implement auxiliary st_table methods for use with temporary tables
sql/table.h:
- add declarations for auxiliary methods of st_table used to work with
temporary tables
tests/mysql_client_test.c:
- if cursors are materialized, a parallel update of the table used
in the cursor may go through: update the test.
sql/sql_cursor.cc:
New BitKeeper file ``sql/sql_cursor.cc'' -- implementation of server side
cursors
sql/sql_cursor.h:
New BitKeeper file ``sql/sql_cursor.h'' - declarations for
server side cursors.

This bug occurs when some trigger for table used by DML statement is created
or changed while statement was waiting in lock_tables(). In this situation
prelocking set which we have calculated becames invalid which can easily lead
to errors and even in some cases to crashes.
With proposed patch we no longer silently reopen tables in lock_tables(),
instead caller of lock_tables() becomes responsible for reopening tables and
recalculation of prelocking set.
mysql-test/t/trigger.test:
Added tests for bug #12704 "Server crashes during trigger execution".
Unfortunately these tests rely on the order in which tables are locked
by statement so they are non-determenistic and therefore should be disabled.
sql/lock.cc:
mysql_lock_tables():
Now instead of always reopening altered or dropped tables by itself
mysql_lock_tables() can notify upper level and rely on caller doing this.
sql/mysql_priv.h:
Now mysql_lock_tables() can either reopen deleted or altered tables by itself
or notify caller about such situation through 'need_reopen' argument and rely
on it in this.
Also lock_tables() has new 'need_reopen' out parameter through which it
notifies caller that some tables were altered or dropped so he needs to reopen
them (and rebuild prelocking set some triggers may change or simply appear).
sql/sp.cc:
sp_add_used_routine():
To be able to restore LEX::sroutines_list to its state right after parsing
we now adjust LEX::sroutines_list_own_last/sroutines_list_own_elements when
we add directly used routine.
sp_remove_not_own_routines():
Added procedure for restoring LEX::sroutines/sroutines_list to their state
right after parsing (by throwing out non-directly used routines).
sp_cache_routines_and_add_tables_for_view()/sp_update_stmt_used_routines():
We should use LEX::sroutines_list instead of LEX::sroutines as source of
routines used by view, since LEX::sroutines is not availiable for view
on second attempt to open it (see comment in open_tables() about it).
sql/sp.h:
sp_remove_not_own_routines():
Added procedure for restoring LEX::sroutines/sroutines_list to their state
right after parsing (by throwing out non-directly used routines).
sql/sp_head.cc:
Removed assert which is no longer always true.
sql/sql_base.cc:
reopen_table():
When we re-open table and do shallow copy of TABLE object we should adjust
pointers to it in associated Table_triggers_list object. Removed nil
operation.
open_tables():
Now this function is able to rebuild prelocking set for statement if it is
needed. It also correctly handles FLUSH TABLES which may occur during its
execution.
lock_tables():
Instead of allowing mysql_lock_tables() to silently reopen altered or dropped
tables let us notify caller and rely on that it will do reopen itself.
This solves the problem when trigger suddenly appears or changed during
mysq_lock_tables().
close_tables_for_reopen():
Added routine for properly preparing for reopening of tables and recalculation
of set of prelocked tables.
sql/sql_handler.cc:
Here we let mysql_lock_tables() to reopen dropped or altered tables by itself.
sql/sql_insert.cc:
Here we let mysql_lock_tables() to reopen dropped or altered tables by itself.
sql/sql_lex.cc:
LEX:
Added 'sroutines_list_own_last' and 'sroutines_list_own_elements' members
which are used for keeping state in which 'sroutines_list' was right after
statement parsing (and for restoring of this list to this state).
sql/sql_lex.h:
LEX:
Added 'sroutines_list_own_last' and 'sroutines_list_own_elements' members
which are used for keeping state in which 'sroutines_list' was right after
statement parsing (and for restoring of this list to this state).
Added chop_off_not_own_tables() method to simplify throwing away list
of implicitly used (prelocked) tables.
sql/sql_prepare.cc:
Now instead of silently reopening altered or dropped tables in
lock_tables() we notify caller and rely on that the caller will
reopen tables.
sql/sql_table.cc:
Here we let mysql_lock_tables() to reopen dropped or altered tables by itself.
sql/sql_trigger.cc:
Added Table_triggers_list::set_table() method to adjust Table_triggers_list
to new pointer to TABLE instance.
sql/sql_trigger.h:
Added Table_triggers_list::set_table() method to adjust Table_triggers_list
to new pointer to TABLE instance.
sql/sql_update.cc:
Now instead of silently reopening altered or dropped tables in
lock_tables() we notify caller and rely on that the caller will
reopen tables.

The idea of the patch is to separate statement processing logic,
such as parsing, validation of the parsed tree, execution and cleanup,
from global query processing logic, such as logging, resetting
priorities of a thread, resetting stored procedure cache, resetting
thread count of errors and warnings.
This makes PREPARE and EXECUTE behave similarly to the rest of SQL
statements and allows their use in stored procedures.
This patch contains a change in behaviour:
until recently for each SQL prepared statement command, 2 queries
were written to the general log, e.g.
[Query] prepare stmt from @stmt_text;
[Prepare] select * from t1 <-- contents of @stmt_text
The chagne was necessary to prevent [Prepare] commands from being written
to the general log when executing a stored procedure with Dynamic SQL.
We should consider whether the old behavior is preferrable and probably
restore it.
This patch refixes Bug#7115, Bug#10975 (partially), Bug#10605 (various bugs
in Dynamic SQL reported before it was disabled).
mysql-test/r/not_embedded_server.result:
Since we don't want to log Dynamic SQL in stored procedures,
now the general log gets only one log entry per SQL statement.
mysql-test/r/sp-error.result:
- remove obsolete tests
- a better error message for the case when a stored procedure that
returns a result set is called from a function
mysql-test/r/trigger.result:
- a better error message for the case when a stored procedure that
returns a result set is called from a trigger
mysql-test/t/sp-error.test:
- a better error message for the case when a stored procedure that
returns a result set is called from a function.
- move the comment to its place (end of file).
mysql-test/t/trigger.test:
- a better error message for the case when a stored procedure that
returns a result set is called from a trigger
sql/item_func.cc:
- we need to pass sql_command explicitly to get_var_with_binlog, because
when creating a query for SQL prepared statement thd->lex->sql_command
points at SQLCOM_EXECUTE, which is not listed in the list of update
queries.
sql/log_event.h:
- remove an extra copy of the previous sentence
sql/mysql_priv.h:
- fix declarations of sql_prepare.cc API
sql/share/errmsg.txt:
- a new error message, when one attempts to execute a prepared statement
which is currently being executed (this can happen only in Dynamic SQL
at the moment).
sql/sp_head.cc:
- extend sp_multi_results_command to return different flags for a
command (and rename it)
- add support for SQLCOM_PREPARE,SQLCOM_EXECUTE, SQLCOM_DEALLOCATE
to sp_get_flags_for_command
- replace multiple boolean sp_head members with uint m_flags
- a fix for a crash when user variables are used in a stored procedure
and binlog is on. A temporary fix for Bug#12637 "SP crashes the server
if it has update query with user var & binlog is enabled", which actually
stands for stored functions: now instead of a crash we break
replication if a user variable is used in a stored function which
is executed in prelocked mode.
sql/sp_head.h:
- replace multiple boolean flags of sp_head with uint m_flags;
- add flag CONTAINS_DYNAMIC_SQL
- use this flag to error if a stored procedure with Dynamic SQL is
called from a function or trigger.
sql/sql_class.cc:
- Statement_map::insert should not delete a statement if it exists,
now it's done externally to be able to handle the case when the
statement being deleted is in use.
- remove extra code (free_list is already reset in free_items)
sql/sql_lex.cc:
- add lex->stmt_prepare_mode; we can't rely on thd->command any more,
because we don't reset it any more (Dynamic SQL requirement is that
PS are as little intrusive as possible).
sql/sql_lex.h:
- declare bool LEX::stmt_prepare_mode
sql/sql_parse.cc:
- move prepared statement code to sql_prepare.cc
- change declarations (refactored code)
- better error message when one attempts to use Dynamic SQL or a
stored procedure that returns a result set in a function or trigger.
sql/sql_prepare.cc:
- major refactoring to ensure PREPARE/EXECUTE commands do not reset global THD
state and allow their use in stored procedures.
- add Prepared_statement::flags and use it to ensure no recursive execution
of a prepared statement is possible
- better comments
sql/sql_yacc.yy:
- enable PREPARE/EXECUTE/DEALLOCATE in stored procedures
- produce an error message on attempt to use PREPARE/EXECUTE/DEALLOCATE
in a stored function or trigger
mysql-test/r/sp-dynamic.result:
- sp-dynamic.test results
mysql-test/t/sp-dynamic.test:
- a new test for PREPARE/EXECUTE/DEALLOCATE in stored procedures.
"Interleaved SPs execution is now binlogged properly, "SELECT spfunc()" is binlogged too.
The known remaining issue is binlogging/replication of "a routine is deleted while it is executed" scenario.

"Process NATURAL and USING joins according to SQL:2003".
* Some of the main problems fixed by the patch:
- in "select *" queries the * expanded correctly according to
ANSI for arbitrary natural/using joins
- natural/using joins are correctly transformed into JOIN ... ON
for any number/nesting of the joins.
- column references are correctly resolved against natural joins
of any nesting and combined with arbitrary other joins.
* This patch also contains a fix for name resolution of items
inside the ON condition of JOIN ... ON - in this case items must
be resolved only against the JOIN operands. To support such
'local' name resolution, the patch introduces a stack of
name resolution contexts used at parse time.
NOTICE:
- This patch is not complete in the sense that
- there are 2 test cases that still do not pass -
one in join.test, one in select.test. Both are marked
with a comment "TODO: WL#2486".
- it does not include a new test specific for the task

Name_resolution_context
- commented old code
- standardized formatting
sql/mysql_priv.h:
- refactored the find_field_in_XXX procedures,
- added a new procedure for natural join table references,
- renamed the find_field_in_XXX procedures to clearer names
sql/sp.cc:
- pass the top-most list of the FROM clause to setup_tables
- extra parameter to find_field_in_tables
sql/sql_acl.cc:
- renamed find_field_in_table => find_field_in_table_ref
- extra parameter to find_field_in_table_ref
- commented old code
sql/sql_base.cc:
This file contains the core of the implementation of the processing
of NATURAL/USING joins (WL#2486).
- added many comments to old code
- refactored the group of find_field_in_XXX procedures, and added a
new procedure for natural joins. There is one find_field_in_XXX procedure
per each type of table reference (stored table, merge view, or natural
join); one meta-procedure that selects the correct one depeneding on the
table reference; and one procedure that goes over a list of table
referenes.
- NATURAL/USING joins are processed through the procedures:
mark_common_columns, store_natural_using_join_columns,
store_top_level_join_columns, setup_natural_join_row_types.
The entry point to processing NATURAL/USING joins is the
procedure 'setup_natural_join_row_types'.
- Replaced the specialized Field_iterator_XXX iterators with one
generic iterator over the fields of a table reference.
- Simplified 'insert_fields' and 'setup_conds' due to encapsulation of
the processing of natural joins in a separate set of procedures.
sql/sql_class.h:
- Commented old code.
sql/sql_delete.cc:
- Pass the FROM clause to setup_tables.
sql/sql_help.cc:

Needed to support an ugly trick to resolve inserted columns only in
the first table.
- Added Name_resolution_context::[first | last]_name_resolution_table.
- Commented old code
sql/sql_lex.cc:

- Added new class Natural_join_column to hide the heterogeneous
representation of column references for stored tables and for
views.
- Added a new list TABLE_LIST::next_name_resolution_table to
support name resolution with NATURAL/USING joins. Also added
other members to TABLE_LIST to support NATURAL/USING joins.
- Added a generic iterator over the fields of table references
of various types - class Field_iterator_table_ref
sql/table.h:

cause crash on update".
Let us update "thd" pointer in LEX, all its units and in LEX::result before
executing statement in trigger body, since triggers are associated with TABLE
object and because of this can be used in different threads.
mysql-test/r/trigger.result:
Added test case for bug #11973 "SELECT .. INTO var_name; in trigger cause
crash on update".
mysql-test/t/trigger.test:
Added test case for bug #11973 "SELECT .. INTO var_name; in trigger cause

sql/item_subselect.cc:
subselect_engine:
Moved implementation of set_thd() method to item_subselect.cc,
since now it also sets "thd" for subselect_engine::result.
sql/item_subselect.h:
subselect_engine:
Moved implementation of set_thd() method to item_subselect.cc,
since now it also sets "thd" for subselect_engine::result.
sql/sql_class.h:
select_result:
Added set_thd() method for updating select_result::thd value (we need this
in cases when statement to which this select_result belongs will be used
in different threads, as it happens for statements in trigger body).
multi_delete/multi_update:
Got rid of redundant "thd" member (we already have it in select_result).
sql/sql_delete.cc:
multi_delete:
Got rid of redundant "thd" member (we already have it in select_result).
sql/sql_lex.h:
st_select_lex_unit:
Added set_thd() method for updating st_select_lex_unit::thd value
(we need this in cases when statement to which this unit belongs will
be used in different threads, as it happens for statements in trigger body).
We don't update thd of select_result pointed by st_select_lex_unit::result
in this method, since it is either have too short lifetime (i.e. created for
each execution) or is accessible via Item_subquery or LEX::result and thus
already taken care of.
sql/sql_parse.cc:
multi_delete:
Got rid of redundant "thd" member (we already have it in select_result).
sql/sql_prepare.cc:
reinit_stmt_before_use():
We have to update "thd" pointer in LEX, all its units and in LEX::result,
since statements which belong to trigger body are associated with TABLE
object and because of this can be used in different threads.
sql/sql_update.cc:
multi_update:
Got rid of redundant "thd" member (we already have it in select_result).
"Triggers have the wrong namespace"
"Triggers: duplicate names allowed"

mysql-test/r/information_schema.result:
Added tests for new INFORMATION_SCHEMA.TRIGGERS view and SHOW TRIGGERS command.
mysql-test/r/information_schema_db.result:
INFORMATION_SCHEMA.TRIGGERS view was added.
mysql-test/r/rpl_sp.result:
Now DROP TRIGGER interprets first part of trigger identifier as database

mysql-test/r/trigger.result:
Now DROP TRIGGER interprets first part of trigger identifier as database

Added test checking that triggers have database wide namespace.
Added test for bug #8791 "Triggers: Allowed to create triggers on a subject
table in a different DB".
mysql-test/r/view.result:
Now DROP TRIGGER interprets first part of trigger identifier as database
name and not as table name. Adjusted tests properly.
mysql-test/t/information_schema.test:
Added tests for new INFORMATION_SCHEMA.TRIGGERS view and SHOW TRIGGERS command.
mysql-test/t/rpl_sp.test:
Now DROP TRIGGER interprets first part of trigger identifier as database
name and not as table name. Adjusted tests properly.
mysql-test/t/trigger.test:
Now DROP TRIGGER interprets first part of trigger identifier as database

Added test checking that triggers have database wide namespace.
Added test for bug #8791 "Triggers: Allowed to create triggers on a subject
table in a different DB".
mysql-test/t/view.test:
Now DROP TRIGGER interprets first part of trigger identifier as database
name and not as table name. Adjusted tests properly.
sql/handler.cc:
Added .TRN tho the list of known file extensions assoicated with tables.
sql/item.h:
trg_action_time_type/trg_event_type enums:
Added TRG_ACTION_MAX/TRG_EVENT_MAX elements which should be used instead of
magical values in various loops where we iterate through all types of trigger
action times or/and trigger event types.
sql/lex.h:
Added new symbol "TRIGGERS".
sql/mysql_priv.h:
Added declaration of constant holding extension for trigger name (.TRN) files.
sql/mysqld.cc:
Added statistical variable for SHOW TRIGGERS command.
sql/share/errmsg.txt:
Added error message saying that one attempts to create trigger in wrong schema.
sql/sp.cc:
Replaced magical values with TRG_EVENT_MAX/TRG_ACTION_MAX constants.
sql/sql_base.cc:
open_unireg_entry():
Now Table_triggers_list::check_n_load() has one more argument which
controls whether we should prepare Table_triggers_list with fully functional
triggers or load only their names.
sql/sql_lex.h:
Added element for new SHOW TRIGGERS command to enum_sql_command enum.
sql/sql_parse.cc:
prepare_schema_table():
Added support for SHOW TRIGGERS statement.
sql/sql_show.cc:
Added new INFORMATION_SCHEMA.TRIGGERS view and SHOW TRIGGERS command.
sql/sql_table.cc:
mysql_rm_table_part2():
Replaced simple deletion of .TRG file with call to
Table_triggers_list::drop_all_triggers which will also delete .TRN files
for all triggers associated with table.
sql/sql_trigger.cc:
Now triggers have database wide namespace. To support it we create special .TRN
file with same name as trigger for each trigger. This file contains name of
trigger's table so one does not need to specify it explicitly in DROP TRIGGER.
Moreover DROP TRIGGER treats first part of trigger identifier as database name
now. Updated mysql_create_or_drop_trigger() routine and
Table_triggers_list::create_trigger()/drop_trigger()/check_n_load() methods
accordingly. Added add_table_for_trigger() routine and
Table_triggers_list::drop_all_triggers() method.
Added Table_triggers_list::get_trigger_info() for obtaining trigger metadata.
sql/sql_trigger.h:
Table_triggers_list:
Use TRG_EVENT_MAX, TRG_ACTION_MAX instead of magic values.
Added get_trigger_info() method for obtaining trigger's meta-data.
Added drop_all_triggers() method which drops all triggers for table.
Added declarations of trg_action_time_type_names/trg_event_type_names
arrays which hold names of triggers action time types and event types.
sql/sql_yacc.yy:
Changed grammar for CREATE/DROP TRIGGER to support database wide trigger
namespace. Added new SHOW TRIGGERS statement.
sql/table.h:
enum enum_schema_tables:
Added constant for new INFORMATION_SCHEMA.TRIGGERS view.
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)

of stored routines definitions even if we already have some tables open and
locked. To avoid deadlocks in this case we have to put certain restrictions
on locking of mysql.proc table.
This allows to use stored routines safely under LOCK TABLES without explicitly
mentioning mysql.proc in the list of locked tables. It also fixes bug #11554
"Server crashes on statement indirectly using non-cached function".
mysql-test/r/sp-error.result:
Added test which checks that now we can read stored routines definitions
under LOCK TABLES even if we have not locked mysql.proc explicitly. Also
added check for restrictions which this ability puts on mysql.proc locking.
Updated test for bug #9566 to correspond this new situation.

sql/lock.cc:
get_lock_data():
To be able to open and lock for reading system tables like 'mysql.proc',
when we already have some tables opened and locked, and avoid deadlocks
we have to disallow write-locking of these tables with any other tables.
sql/mysql_priv.h:
open_table() has new parameter which allows to open table even if some-one
has done a flush or holding namelock on it.
sql/share/errmsg.txt:
Added error message saying that one cannot write-lock some of system tables
with any other tables.
sql/sp.cc:
open_proc_table_for_read()/close_proc_table():
Added functions to be able open and close mysql.proc table when we already
have some tables open and locked.
open_proc_table_for_update():
Added function to simplify opening of mysql.proc for updates.
db_find_routine_aux()/db_find_routine()/db_update_routine()/...
Moved responsibility for opening mysql.proc table from db_find_routine_aux()
one level up, since this level knows better which type of table access for
reading of for update it needs.
sp_function_exists():
Removed unused function.
sql/sp.h:
sp_function_exists():

sql/sql_base.cc:
open_table():

locking, but thanks to them can be open and locked even if we already have
some open and locked.
sql/sql_class.cc:
Moved THD members holding information about open and locked tables to separate

crash if referencing a table" and several other related bugs.
Fix for bug #11834 "Re-execution of prepared statement with dropped function
crashes server." which was spotted during work on previous bugs.
Also couple of nice cleanups:
- Replaced two separate hashes for stored routines used by statement with one.
- Now instead of doing one pass through all routines used in statement for
caching them and then doing another pass for adding their tables to table
list, we do only one pass during which do both things.
mysql-test/r/sp-error.result:
Added test for bug #11834 "Re-execution of prepared statement with dropped
function crashes server" also covering handling of prepared statements
which use stored functions but does not require prelocking.
mysql-test/r/sp.result:
Updated test for LOCK TABLES with views in table list.
(Old version of statement used in this test will work ok now, since prelocking
algorithm was tuned and will lock only one multi-set of tables for each routine
even if this routine is used in several different views).
mysql-test/r/trigger.result:
Added several tests for triggers using tables.
mysql-test/t/sp-error.test:
Added test for bug #11834 "Re-execution of prepared statement with dropped
function crashes server" also covering handling of prepared statements
which use stored functions but does not require prelocking.
mysql-test/t/sp.test:
Updated comment about recursive views to reflect current situation.
Updated test for LOCK TABLES with views in table list.
(Old version of statement used in this test will work ok now, since prelocking
algorithm was tuned and will lock only one multi-set of tables for each routine
even if this routine is used in several different views).
mysql-test/t/trigger.test:
Added several tests for triggers using tables.
sql/item_func.cc:
Item_func_sp::cleanup():
By next statement execution stored function can be dropped or altered so
we can't assume that sp_head object for it will be still valid.
sql/sp.cc:
- Added Sroutine_hash_entry structure that represents element in the set of
stored routines used by statement or routine. We can't as before use
LEX_STRING for this purprose because we want link all elements of this set
in list.
- Replaced sp_add_to_hash() with sp_add_used_routine() which takes into account
that now we use one hash for stored routines used by statement instead of two
and which mantains list linking all elelemnts in this hash.
- Renamed sp_merge_hash() to sp_update_sp_used_routines().
- Introduced sp_update_stmt_used_routines() for adding elements to the set of
routines used by statement from another similar set for statement or routine.
This function will also mantain list linking elements of destination set.
- Now instead of one sp_cache_routines() function we have family of
sp_cache_routines_and_add_tables() functions which are also responsible for
adding tables used by routines being cached to statement table list. Nice
optimization - thanks to list linking all elements in the hash of routines
used by statement we don't need to perform several iterations over this hash
(as it was before in cases when we have added new elements to it).
sql/sp.h:
Added declarations of functions used for manipulations with set (hash) of stored
routines used by statement.
sql/sp_head.cc:
sp_name::init_qname():
Now sp_name also holds key identifying routine in the set (hash) of
stored routines used by statement.
sp_head:
Instead of two separate hashes sp_funs/m_spprocs representing sets of stored
routines used by this routine we use one hash - m_sroutines.
sp_instr_set_trigger_field:
Added support for subqueries in assignments to row accessors in triggers.
Removed definition of sp_add_sp_tables_to_table_list() and auxilary functions
since now we don't have separate stage on which we add tables used by routines
used by statement to table list for prelocking. We do it on the same stage as
we load those routines in SP cache. So all this functionality moved to
sp_cache_routines_and_add_tables() family of functions.
sql/sp_head.h:
sp_name:
Now this class also holds key identifying routine in the set (hash) of stored
routines used by statement.
sp_head:
Instead of two separate hashes sp_funs/m_spprocs representing sets of stored
routines used by this routine we use one hash - m_sroutines.
sp_instr_set_trigger_field:
Added support for subqueries in assignments to row accessors in triggers.
Removed declaration of sp_add_sp_tables_to_table_list() since now we don't have
separate stage on which we add tables used by routines used by statement to
table list for prelocking. We do it on the same stage as we load those routines
in SP cache.
sql/sql_base.cc:
open_tables():
- LEX::spfuns/spprocs hashes were replaced with one LEX::sroutines hash.
- Now instead of doing one pass through all routines used in statement for
caching them and then doing another pass for adding their tables to table
list, we do only one pass during which do both things. It is easy to do
since all routines in the set of routines used by statement are linked in
the list. This also allows us to calculate table list for prelocking more
precisely.
- Now triggers properly inform prelocking algorithm about tables they use.
sql/sql_lex.cc:
lex_start():
Replaced LEX::spfuns/spprocs with with one LEX::sroutines hash.
Added LEX::sroutines_list list linking all elements in this hash.
st_lex::st_lex():
Moved definition of LEX constructor to sql_lex.cc file to be able
use sp_sroutine_key declaration from sp.h in it.
sql/sql_lex.h:
LEX:
Replaced two separate hashes for stored routines used by statement with one.
Added list linking all elements in this hash to be able to iterate through all
elements and add new elements to this hash at the same time.
Moved constructor definition to sql_lex.cc.
sql/sql_parse.cc:
mysql_execute_command():
Replaced LEX::spfuns/spprocs with one LEX::sroutines hash.
sql/sql_trigger.cc:
Added missing GNU GPL notice.
Table_triggers_list::check_n_load()
Added initialization of sroutines_key which stores key representing
triggers of this table in the set (hash) of routines used by this statement.
sql/sql_trigger.h:
Added missing GNU GPL notice.
Table_triggers_list:
Added sroutines_key member to store key representing triggers of this
table in the set (hash) of routines used by this statement.
Declared sp_cache_routines_and_add_tables_for_triggers() as friend since
it needs access to sroutines_key and trigger bodies.
sql/sql_yacc.yy:
- Now we use sp_add_used_routine() instead of sp_add_to_hash() for adding
elements to the set of stored routines used in statement.
- Enabled support of subqueries as right sides in assignments to triggers' row
accessors.

The reason it happened was that both, JOIN::cleanup() and JOIN::join_free(),
went over all nested joins and called cleanup/join_free for them.
For that:
- split recursive and non-recursive parts of JOIN::cleanup() and
JOIN::join_free()
- rename JOIN::cleanup to JOIN::destroy, as it actually destroys its
argument
- move the recursive part of JOIN::cleanup to st_select_lex::cleanup
- move the non-recursive part of JOIN::join_free to the introduced
method JOIN::cleanup().
sql/sql_lex.h:
Add st_select_lex::cleanup, a counterpart of st_select_lex_unit::cleanup()
sql/sql_select.cc:
- remove two unused arguments from return_zero_rows
- split JOIN::join_free and JOIN::cleanup to recursive and non-recursive
parts.
- note, the assert in JOIN::join_free _does_ fail in having.test.
We have two options: a) propagate `full' flag to the nested joins.
We did it before, and this patch didn't change it. If so, we
can end up cleaning up an uncacheable JOIN (that is, the join that
we might need again).
b) evaluate own 'full' flag on every level. In this case, we might
end up with tables freed in mysql_unlock_read_tables, but not
cleaned up properly, and this may be even worse. The test suite
passes with both approaches, but not with the assert.
sql/sql_select.h:
- declarations for JOIN::cleanup() and JOIN::join_free()
sql/sql_union.cc:
Add st_select_lex::cleanup, a counterpart of st_select_lex_unit::cleanup():
move the recursive part of JOIN::cleanup to it.

sql/item.h:

sql/mysql_priv.h:

sql/sp_head.cc:
Make is_stmt_prepare_or_first_sp_execute really work: reset SP state
to EXECUTED after execution.
sql/sql_base.cc:
allocate_view_names flag of insert_fields is removed.
The purpose of this variable was to amend the case when a view
is replaced with a base table between subsequent executions of a prepared
statement: in that case the new table theoretically can be used instead
of the view. If allocate_view_names was set,
all the references to the view expressions were replaced with Item_field's
which in turn could have been resolved by their names.
But this approach doesn't work for other reasons, so let's not try
to help what must be solved by TDC.
sql/sql_class.h:
Add is_first_sp_execute() helper method.
sql/sql_handler.cc:
insert_fields signature changed.
sql/sql_lex.h:

In order to make multi-delete SP friendly we need to have all table
locks for the elements of main statement table list properly set
at the end of parsing.
Also performed small cleanup: We don't need relink_tables_for_multidelete()
any longer since the only case now when TABLE_LIST::correspondent_table
is non-zero are tables in auxilary table list of multi-delete and these
tables are handled specially in mysql_multi_delete_prepare().
mysql-test/r/sp-threads.result:
Added test case for bug #11158 "Can't perform multi-delete in stored
procedure".
mysql-test/t/sp-threads.test:
Added test case for bug #11158 "Can't perform multi-delete in stored
procedure".
sql/mysql_priv.h:
- Removed third argument from the declaration of multi_delete_precheck()
as nowdays we calculate number of tables in multi-delete from which
we are going to delete rows right at the end of statement parsing.
- Introduced definition of multi_delete_set_locks_and_link_aux_tables()
which is responsible for propagation of proper table locks from
multi-delete's auxilary table list to the main list and binding
corresponding tables in these two lists.
sql/sql_base.cc:
Removed relink_tables_for_multidelete() routine and its invocations.
We don't need them in 5.0 since the only case now when
TABLE_LIST::correspondent_table is non-zero are tables in auxilary table
list of multi-delete and these tables are handled specially in
mysql_multi_delete_prepare().
sql/sql_lex.h:
LEX::table_count
Added description of new role of this LEX member for multi-delete.
Now for this statement we store number of tables from which we should
delete records there.
sql/sql_parse.cc:
multi_delete_precheck():
Moved code which is responsible for iterating through auxilary table
list and binding its elements with corresponding elements of main
table list, and properly updating locks in it to separate function -
multi_delete_set_locks_and_link_aux_tables(). This is because in order
to make multi-delete SP friendly we need to have all locks set properly
at the end of statement parsing. So we are introducing new function
which will be called from parser.
We also calculate number of tables from which we are going to perform
deletions there and store this number for later usage in
LEX::table_count.
Also removed some no longer needed code.
sql/sql_prepare.cc:
mysql_test_multidelete():
Now multi_delete_precheck() takes only two arguments, so we don't
need to pass fake third parameter.
sql/sql_yacc.yy:

In order to make multi-delete SP friendly we need to have all table
locks for the elements of main statement table list properly set

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:

from prepared statement prepare.
sql/sql_class.h:

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:

it will be created in the runtime mem root and freed in the end of
execution.

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.

"the server side preparedStatement error for LIMIT placeholder",
which moves all uses of LIMIT clause from PREPARE to OPTIMIZE
and later steps.
After-review fixes.
mysql-test/r/group_min_max.result:
Test results fixed for EXPLAINs when using GROUP_MIN_MAX access plan.
sql/item_subselect.cc:
Move setting of the internal LIMIT used for IN/ALL/ANY/EXISTS
subqueries to one place: Item_exists_subselect::fix_length_and_dec().
This implies that unit->select_limit_cnt is not set until the item is
fixed. This is OK, as now LIMIT values are not used until JOIN::optimize.
sql/mysql_priv.h:
setup_tables no longer needs a special flag for the case when
it's called from JOIN::reinit() (we don't need to call setup_tables
between two executions of a correlated subquery).
sql/opt_range.cc:
Fix a glitch in GROUP_MIN_MAX access plan: we should use table metadata,
not field data, to evaluate max_used_key_length, which is then
used for explain.
sql/sp.cc:
- setup_tables signature changed.
sql/sql_base.cc:
- setup_tables no longer needs a special mode for subqueries.
Unused checks were removed.
sql/sql_delete.cc:
- setup_tables signature changed
sql/sql_help.cc:
- setup_tables signature changed
sql/sql_insert.cc:
- setup_tables signature changed
sql/sql_lex.cc:
Consolidate setting of internal LIMIT for IN/ALL/ANY/EXISTS subqeries
in one place, and hence remove it from st_select_lex::test_limit().
sql/sql_lex.h:
Cleanup signature of st_select_lex_unit::init_prepare_fake_select_lex().
sql/sql_load.cc:
- setup_tables signature changed
sql/sql_olap.cc:
- setup_tables signature changed
sql/sql_parse.cc:
- st_select_lex_unit::set_limit() signature changed
sql/sql_select.cc:
Move setting of JOIN::select_limit from JOIN::prepare
to JOIN::optimize. At prepare, limit is unknown yet.
Remove excessive cleanups from JOIN::reinit which were overwriting
join->join_tab[i]->table->used_keys. This fixes the bug which was triggered
by the change in item_subselect.cc.
sql/sql_union.cc:
Class st_select_lex_unit was changed to avoid calls to
st_select_lex_unit::set_limit from places where it may be unknown.
Now unit->select_limit_cnt is set at ::exec().
st_select_lex_unit::init_prepare_fake_select_lex():
- move out set_limit functionality
- remove a few lines of dead code.
st_select_lex_unit::prepare():
- now we don't call set_limit at the time of prepare, so the value
of unit->select_limit_cnt may be unknown here. Use sl->select_limit
instead.
st_select_lex_unit::exec():
- cleanup
- call set_limit explicitly as it has been moved out of
init_prepare_fake_select_lex.
sql/sql_update.cc:
- setup_tables signature changed
We will however give a warning when opening such a table that users should use ALTER TABLE ... FORCE to fix
the table. In future release we will fix that REPAIR TABLE will be able to handle this case
sql/sql_lex.h:
Support for ALTER TABLE ... FORCE
sql/sql_table.cc:
CHECK TABLE now gives a note if table->s->crashed was set
sql/sql_yacc.yy:
Support for ALTER TABLE ... FORCE
sql/table.cc:
Fix that we can read tables with the 'older' decimal format used in 5.0.3 & 5.0.4
(Now we store display length in the .frm table while we previously stored precision)
sql/table.h:
Store in TABLE_SHARE version number of MySQL where table was created (or checked)
