Bug #18361: Triggers on mysql.user table cause server crash
Because they do not work, we do not allow creating triggers on tables
within the 'mysql' schema.
(They may be made to work and re-enabled at some later date, but not
in 5.0 or 5.1.)
mysql-test/r/trigger.result:
Add new results
mysql-test/t/trigger.test:
Add new regression test for creating triggers on system schema
sql/share/errmsg.txt:
Add new error message
sql/sql_trigger.cc:
Disallow creating triggers on tables in the 'mysql' schema
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:
Touch the code that reads thd->db (cleanup).
sql/log_event.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/slave.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/slave.h:
Remove a declaration for a method that is used only in one module.
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.
in older version.
The problem is that TRN-files created in "old" versions contain
junk in trigger_table field, which is not acceptable in "new" versions.
sql/parse_file.cc:
1. Made parse_escaped_string() available globally;
2. Polishing: fixing the comments.
sql/parse_file.h:
Made parse_escaped_string() available globally.
sql/sql_trigger.cc:
1. Polishing
2. Removed declaration of global handle_old_incorrect_sql_modes()
since it is not used anymore.
3. Added a hook to support invalid "trigger_table" field in TRN-file
from old versions.
triggers".
Applying ALTER/OPTIMIZE/REPAIR TABLE statements to transactional table or to
table of any type on Windows caused disappearance of its triggers.
Bug was introduced in 5.0.19 by my fix for bug #13525 "Rename table does not
keep info of triggers" (see comment for sql_table.cc for more info).

mysql-test/r/trigger.result:
Added test-case covering handling of triggers when one does ALTER TABLE which
should move table to different database.
mysql-test/t/trigger.test:
Added test-case covering handling of triggers when one does ALTER TABLE which

sql/sql_table.cc:
mysql_alter_table():
Removal of strdup() which is no longer necessary allows us to preserve
nice assumption that "(new_db != db || new_table != table_name) indicates
that table will be renamed. So now we really can use this condition to
avoid updating trigger definitions when table is not renamed.
Note that we can't use (alter_info->flags & ALTER_RENAME) condition instead
since it can be also true when we do "ALTER TABLE t1 RENAME TO t1".
sql/sql_trigger.cc:
Table_triggers_list::change_table_name():
Mentioned assumption that subject table is not renamed to itself in method
description. Added DBUG_ASSERT() to catch wrong usage of this method.

qualified subject table" which was introduced during work on bug #13525
"Rename table does not keep info of triggers".
The bug was caused by the fact that during reconstruction of CREATE TRIGGER
statement stored in .TRG file which happened during RENAME TABLE we damaged
trigger definition in case when it contained fully qualified name of subject
table (see comment for sql_yacc.yy for more info).
mysql-test/r/trigger.result:
Added test for bug #17866 "Problem with renaming table with triggers with fully
qualified subject table".
mysql-test/t/trigger.test:
Added test for bug #17866 "Problem with renaming table with triggers with fully
qualified subject table".
sql/sql_trigger.cc:
Table_triggers_list::change_table_name_in_triggers():
Instead of trying to use pointer to the end of subject table identifier
we use pointer to the beginning of FOR lexeme now, so during reconstruction
of CREATE TRIGGER statement in this function we need to add extra space
before part which begins with FOR to get nice trigger definition.
sql/sql_yacc.yy:
trigger_tail:
In this rule we can't rely on using remember_end token after table_ident token,
since value returned depends on whether table name is fully qualified or not.
So instead of trying to get pointer to the end of table identifier we use
pointer to the beginning of FOR lexeme.
The idea is to add DEFINER-clause in CREATE PROCEDURE and CREATE FUNCTION
statements. Almost all support of definer in stored routines had been already
done before this patch.
NOTE: this patch changes behaviour of dumping stored routines in mysqldump.
Before this patch, mysqldump did not dump DEFINER-clause for stored routines
and this was documented behaviour. In order to get full information about stored
routines, one should have dumped mysql.proc table. This patch changes this
behaviour, so that DEFINER-clause is dumped.
Since DEFINER-clause is not supported in CREATE PROCEDURE | FUNCTION statements
before this patch, the clause is covered by additional version-specific comments.
client/mysqldump.c:
Updated the code for dumping stored routines: cover DEFINER-clause
into version-specific comment.
mysql-test/r/gis.result:
Updated result file after adding DEFINER-clause.

sql/sql_trigger.cc:
Renamed trigger_definition_begin into stmt_definition_begin to be used for
triggers and stored routines.
sql/sql_yacc.yy:
Added DEFINER-clause.
The idea of the fix is to extend support of non-SUID triggers for backward
compatibility. Formerly non-SUID triggers were appeared when "new" server
is being started against "old" database. Now, they are also created when
"new" slave receives updates from "old" master.

Let us transfer triggers associated with table when we rename it (but only if
we are not changing database to which table belongs, in the latter case we will
emit error).
mysql-test/r/trigger.result:
Added test for bug #13525 "Rename table does not keep info of triggers".

sql/sql_rename.cc:
rename_tables():
Now after renaming table's .FRM file and updating handler data we call
Table_triggers_list::change_table_name() which is reponsible for
updating .TRG and .TRN files.
sql/sql_table.cc:
mysql_alter_table():
Now in case when ALTER should rename table we call
Table_triggers_list::change_table_name() which is responsible
for updating .TRG and .TRN files after renaming table.
sql/sql_trigger.cc:
Added Table_triggers_list::change_table_name() method and
change_table_name_in_triggers()/trignames() methods responsible for updating
.TRG and .TRN files for table during its renaming.
Two small cleanups - removed versioning for .TRG files (since it was not working
before anyway) and emphasized that type of lock specified in tables list is
unimportant for DROP TABLE (since this statement uses name-locking).
sql/sql_trigger.h:
Table_triggers_list:
Added on_table_names_list member to store pointers and lenghts of
"ON table_name" parts in triggers' definitions to be able easily
change them during RENAME TABLE.
Added change_table_name() method and change_table_name_in_trignames/triggers()
helper methods responsible for updating .TRG and .TRN files.
sql/sql_yacc.yy:
trigger_tail:
To be able properly update triggers' definitions with new table names
when renaming tables we need to know where in CREATE TRIGGER statement
"ON db_name.table_name" part resides.
Small cleanup - let us emphasize that for CREATE TRIGGER statement
lock type which is specified in table list is unimportant since
name-locking is used.
- BUG#15166: Wrong update permissions required to execute triggers
- BUG#15196: Wrong select permission required to execute triggers
The idea of the fix is to check necessary privileges
in Item_trigger_field::fix_fields(), instead of having "special variables"
technique. To achieve this, we should pass to an Item_trigger_field instance
a flag, which will indicate the usage/access type of this trigger variable.
mysql-test/r/trigger-grant.result:
Update the result file.
mysql-test/t/trigger-grant.test:
Add test cases for BUG#15166 and BUG#15196
sql/item.cc:
Item_trigger_field: check appropriate (SELECT/UPDATE) privilege in fix_fields().
sql/item.h:
Add a flag to specify access type for trigger field.
sql/sql_trigger.cc:
"Special variable" technique of checking privileges for NEW/OLD variables
was replaced by checking table- and column-level privileges in
Item_trigger_field::fix_fields().
sql/sql_trigger.h:
"Special variable" technique of checking privileges for NEW/OLD variables
was replaced by checking table- and column-level privileges in

sql/sql_yacc.yy:

There are two main idea of this fix:
- introduce a common function for server and client to split user value
(<user name>@<host name>) into user name and host name parts;
- dump DEFINER clause in correct format in mysqldump.
BitKeeper/etc/ignore:
added client/my_user.c libmysqld/my_user.c sql/my_user.c

The idea is to use Field-classes to implement stored routines
variables. Also, we should provide facade to Item-hierarchy

in expressions).

if inner routine has more local variables than outer one, and
one of its last variables was used as argument to NOT operator".
THD::spcont was non-0 when we were parsing stored routine/trigger
definition during execution of another stored routine. This confused
methods of Item_splocal and forced them use wrong runtime context.
Fix ensures that we always have THD::spcont equal to zero during
routine/trigger body parsing. This also allows to avoid problems
with errors which occur during parsing and SQL exception handlers.

Indeed now that stored procedures CALL is not binlogged, but instead the invoked substatements are,
the restrictions applied by log-bin-trust-routine-creators=0 are superfluous for procedures.
They still need to apply to functions where function calls are written to the binlog (for example as "DO myfunc(3)").
We rename the variable to log-bin-trust-function-creators but allow the old name until some future version (and issue a warning if old name is used).

droping trigger on InnoDB table".
Deadlock occured in cases when we were trying to create two triggers for
the same InnoDB table concurrently and both threads were able to reach
close_cached_table() simultaneously. Bugfix implements new approach to
table locking and table cache invalidation during creation/dropping
of trigger.
No testcase is supplied since bug was repeatable only under high concurrency.
sql/mysql_priv.h:
reopen_name_locked_table():
Changed function signature to make it more robust against erroneous usage.
sql/sql_base.cc:
reopen_name_locked_table():
Changed function signature to make it more robust against erroneous usage.
Obtaining LOCK_open lock is now resposibility of caller.
When searching for the table to open we should not prefer connection's current
database over database which was explicitly specified in TABLE_LIST::db member
(even if database is not explicitly specified for table in original query
TABLE_LIST::db will be set properly at parsing stage).
Fixed behavior of function in cases when error occurs during opening of table.
sql/sql_table.cc:
prepare_for_restore()/prepare_for_repair():
We should not prefer connection's current database over database which was
specified in TABLE_LIST::db member (even if database is not explicitly
specified for table in original query TABLE_LIST::db will be set properly
at parsing stage). Fixed behavior in unlikely case when we are unable
to open table which we are restoring/reparing at the end of preparation
stage.
sql/sql_trigger.cc:
mysql_create_or_drop_trigger():
Now instead of opening and locking table, creating trigger, and then trying
to invalidate all instances of this table in table cache, we obtain name
lock on table first (thus ensuring that no other thread has this table
open), open it, create trigger and then close table therefore releasing lock.
New approach is more in line with other places where change .frm files
(i.e. change table meta-data).
With this change we also get rid of deadlock which occured in cases when we
were trying to create two triggers for the same InnoDB table concurrently
and both threads were able to reach close_cached_table() simultaneously.
(Alternative was to forbid to InnoDB downgrade locks for CREATE/DROP
TRIGGER statements in one way or another but I think that proposed
solution is better long term).
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.
This allows us to use statement replication with functions and triggers
The following things are fixed with this patch:
- NOW() and automatic timestamps takes the value from the main event for functions and triggers (which allows these to replicate with statement level logging)
- No side effects for triggers or functions with auto-increment values(), last_insert_id(), rand() or found_rows()
- Triggers can't return result sets
Fixes bugs:
#12480: NOW() is not constant in a trigger

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

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

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

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/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.
all tables suggested by prelocking algorithm.
Added test for bug #11889 "Server crashes when dropping trigger using stored
routine" (which was fixed by previous patch).
mysql-test/r/trigger.result:
Since we are using open_ltable() now to open table for trigger creation, code
for error when we try to create trigger on view has changed to equivalent one.
Added test for bug #11889 "Server crashes when dropping trigger using stored

mysql-test/t/trigger.test:
Since we are using open_ltable() now to open table for trigger creation, code
for error when we try to create trigger on view has changed to equivalent one.
Added test for bug #11889 "Server crashes when dropping trigger using stored
routine".
sql/sql_trigger.cc:
mysql_create_or_drop_trigger():
It is better to open only table for which we are going to create or drop
trigger with open_ltable() since we don't really need working prelocking
in this case.

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.

#5860 "Multi-table UPDATE does not activate update triggers"
#6812 "Triggers are not activated for INSERT ... SELECT"
#8755 "Trigger is not activated by LOAD DATA".
This patch also implements proper handling of triggers for special forms
of insert like REPLACE or INSERT ... ON DUPLICATE KEY UPDATE.
Also now we don't call after trigger in case when we have failed to
inserted/update or delete row. Trigger failure should stop statement
execution.
I have not properly tested handling of errors which happen inside of
triggers in this patch, since it is simplier to do this once we will be
able to access tables from triggers.
mysql-test/r/trigger.result:
Added tests for triggers behavior for various non-standard forms of
INSERT such as REPLACE and INSERT ... ON DUPLICATE KEY UPDATE.
Also added tests for bugs #5860 "Multi-table UPDATE does not activate
update triggers", #6812 "Triggers are not activated for INSERT ... SELECT"
and #8755 "Trigger is not activated by LOAD DATA".
mysql-test/t/trigger.test:
Added tests for triggers behavior for various non-standard forms of
INSERT such as REPLACE and INSERT ... ON DUPLICATE KEY UPDATE.
Also added tests for bugs #5860 "Multi-table UPDATE does not activate
update triggers", #6812 "Triggers are not activated for INSERT ... SELECT"
and #8755 "Trigger is not activated by LOAD DATA".
sql/item.cc:
Since it turned out that at trigger loading time we can't say in which
buffer TABLE::record[0] or record[1] old version of row will be stored
we have to change our approach to binding of Item_trigger_field to
Field instances.
Now after trigger parsing (in Item_trigger_field::setup_table()) we only
find index of proper Field in the TABLE::field array. Then before trigger
is invoked we set Table_triggers_list::old_field/new_field so they point
to arrays holding Field instances bound to buffers with proper row
versions. And as last step in Item_trigger_field::fix_fields() we get
pointer to Field from those arrays using saved field index.
Item_trigger_field::setup_field()/fix_fields() were changed to implement
this approach.

Item_trigger_field:
- Added field_idx member to store index of Field object corresponding to
this Item in TABLE::field array.
- Added triggers member to be able to access to parent Table_trigger_list
object from fix_fields() method.
- setup_field() no longer needs to know for which type of event this
trigger is, since it does not make decision Field for which buffer
(record[0] or record[1] is appropriate for this Item_trigger_field)
sql/mysql_priv.h:
Added fill_record_n_invoke_before_triggers() methods. They are simple
wrappers around fill_record() which invoke proper before trigger right
after filling record with values.
sql/sql_base.cc:
Added fill_record_n_invoke_before_triggers() methods. They are simple
wrappers around fill_record() which invoke proper before trigger right
after filling record with values.
sql/sql_delete.cc:
mysql_delete():
Now we stop statement execution if one of triggers failed, we also
don't execute after delete trigger if we failed to delete row from
the table (We also pass information about which buffer contains old
version of row to process_triggers()).
multi_delete::send_data()/do_deletes():
Now we also invoke triggers in case of multi-delete.
sql/sql_insert.cc:
mysql_insert():
Moved invocation of before triggers to fill_record_n_invoke_before_triggers()
method. After triggers are now executed as part of write_record().
(as nice side effect now we also stop statement execution if one of
triggers fail).
write_record():
Invoke after insert trigger after performing insert. Also invoke proper
triggers if insert is converted to update or conflicting row is deleted.
Cleaned up error handling a bit - no sense to report error via
handler::print_error if it was not generated by handler method and
was reported before.
Also now we will execute after trigger only if we really have written
row to the table.
select_insert::send_data()/store_values():
We should also execute INSERT triggers for INSERT ... SELECT statement.
sql/sql_load.cc:
read_fixed_length()/read_sep_field():
We should execute INSERT triggers when processing LOAD DATA statement.
Small cleanup in auto-increment related code. Also moved check for
thd->killed which is used to abort LOAD DATA in case of problems
in 'traditional' mode to better place..
sql/sql_trigger.cc:
Since it turned out that at trigger loading time we can't say in which
buffer TABLE::record[0] or record[1] old version of row will be stored
we have to change our approach to binding of Item_trigger_field to

to arrays holding Field instances bound to buffers with proper row
versions. And as last step in Item_trigger_field::fix_fields() we get
pointer to Field from those arrays using saved field index.
Table_triggers_list methods were changed to implement this approach
(see also comments for sql_trigger.h).
sql/sql_trigger.h:

to arrays holding Field instances bound to buffers with proper row
versions. And as last step in Item_trigger_field::fix_fields() we get
pointer to Field from those arrays using saved field index.
Changed Table_triggers_list to implement this new approach:
- Added record1_field member to store array of Field objects bound
to TABLE::record[1] buffer (instead of existing old_field member)
- Added new_field member and changed meaning of old_field member.
During trigger execution they should point to arrays of Field objects
bound to buffers holding new and old versions of row respectively.
- Added 'table' member to be able to get access to TABLE instance
(for which this trigger list object was created) from process_triggers()
method.
- Now process_triggers() method sets old_field and new_field members
properly before executing triggers body (basing on new
old_row_is_record1 parameter value).
- Renamed prepare_old_row_accessors_method() to prepare_record1_accessors()
Also added has_before_update_triggers() method which allows to check
whenever any before update triggers exist for table.
sql/sql_update.cc:
mysql_update():
Now we invoke before triggers in fill_record_n_invoke_before_triggers()
method. Also now we abort statement execution when one of triggers fail.
safe_update_on_fly():
When we are trying to understand if we can update first table in multi
update on the fly we should take into account that BEFORE UPDATE
trigger can change field values.
multi_update::send_data()/do_updates()
We should execute proper triggers when doing multi-update
(in both cases when we do it on the fly and using temporary tables).

To do this we have to check for existence of .TRG file and delete it
(until the moment when we will store trigger definitions in the same
.FRM file as table description).
sql/sql_trigger.cc:
Made constant holding extension for trigger files externally visible.
Improved handling of situations when we encounter error during
CREATE PROCEDURE (FUNCTION/TRIGGER/...) and bail out of yyparse()
without restoring proper THD::lex.
sql/sp.cc:
We do not need to call sp_head::restore_lex() explicitly to restore right
value of THD::lex in case when we have encountered error during parsing.
Now we do this in sp_head::~sp_head() instead.
sql/sp_head.cc:
sp_head::destroy():
Fixed cleaning up of stack of auxilary LEXes.
We also restore right value of THD::lex during this process now.
sql/sql_parse.cc:
We do not need to call sp_head::restore_lex() explicitly to restore right
value of THD::lex in case when we have encountered error during parsing.
Now we do this in sp_head::~sp_head() instead.
sql/sql_prepare.cc:
We do not need to call sp_head::restore_lex() explicitly to restore right
value of THD::lex in case when we have encountered error during parsing.
Now we do this in sp_head::~sp_head() instead.
sql/sql_trigger.cc:
We do not need to call sp_head::restore_lex() explicitly to restore right
value of THD::lex in case when we have encountered error during parsing.
Now we do this in sp_head::~sp_head() instead.
