erroneous check
Problem: Actually there were two problems in the server code. The check
for SQLCOM_FLUSH in SF/Triggers were not according to the existing
architecture which uses sp_get_flags_for_command() from sp_head.cc .
This function was also missing a check for SQLCOM_FLUSH which has a
problem combined with prelocking. This changeset fixes both of these
deficiencies as well as the erroneous check in
sp_head::is_not_allowed_in_function() which was a copy&paste error.

mysql-test/r/trigger.result:

mysql-test/t/sp-error.test:
FLUSH can create a problem with prelocking, hence it's disabled.
There is a better way to check this than a check in the parser.
Now we use sp_get_flags_for_command() and the error returned is
different.
mysql-test/t/trigger.test:
FLUSH can create a problem with prelocking, hence it's disabled.
There is a better way to check this than a check in the parser.
Now we use sp_get_flags_for_command() and the error returned is
different.
sql/sp_head.cc:
FLUSH and RESET are not allowed inside a SF/Trigger.
Because they don't imply a COMMIT sp_head::HAS_COMMIT_OR_ROLLBACK
cannot be used. Two new flags were introduced for that reason.
sql/sp_head.h:
Don't check m_type as this check is erroneous. This is probably
a copy and paste error when moving code from somewhere else. Another
fact which supports this was prefixing the enum value with the name
of class sp_head.
Adding two new flags HAS_SQLCOM_RESET and HAS_SQLCOM_FLUSH. The values
are 2048 and 4096 because in the 5.1 branch there are already new flags
which are with values up-to 1024.
sql/sql_parse.cc:
FLUSH can cause a problem with prelocking in SF/Trigger and
therefore is already disabled. RESET is also disabled because
is handled by the same code as FLUSH. We won't allow RESET inside
SF/Trigger at that stage without thorough analysis. The check for
them is already done in the parser by calling
is_not_allowed_in_function()
sql/sql_yacc.yy:
By listing SQLCOM_FLUSH as command which implies COMMIT
in sp_get_flags_for_command() the check in sql_yacc.yy is
obsolete.
User name (host name) has limit on length. The server code relies on these
limits when storing the names. The problem was that sometimes these limits
were not checked properly, so that could lead to buffer overflow.
The fix is to check length of user/host name in parser and if string is too
long, throw an error.

It was hard to distinguish case, when one was unable to create trigger
on the table because trigger with same action time and event already
existed for this table, from the case, when one tried to create trigger
with name which was already occupied by some other trigger, since in
both these cases we emitted ER_TRG_ALREADY_EXISTS error and message.
Now we emit ER_NOT_SUPPORTED_YET error with appropriate additional
message in the first case. There is no sense in introducing separate
error for this situation since we plan to get rid of this limitation
eventually.

Bug #18361: Triggers on mysql.user table cause server crash
Because they do not work, we do not allow creating triggers on tables

in 5.0 or 5.1.)

INSERT triggers".
In cases when REPLACE was internally executed via update and table had
on update (on delete) triggers defined we exposed the fact that such
optimization used by callng on update (not calling on delete) triggers.
Such behavior contradicts our documentation which describes REPLACE as
INSERT with optional DELETE.
This fix just disables this optimization for tables with on delete triggers.
The optimization is still applied for tables which have on update but have
no on delete triggers, we just don't invoke on update triggers in this case
and thus don't expose information about optimization to user.
Also added test coverage for values returned by ROW_COUNT() function (and
thus for values returned by mysql_affected_rows()) for various forms of
INSERT.
mysql-test/r/insert.result:

sql/sql_insert.cc:
write_record():
We should not expose that internally we sometimes execute REPLACE
via UPDATE instead of documented INSERT + DELETE pair. So we should not
use this optimization for tables with on delete triggers. OTOH it is ok
to use it for tables which have on update but have no on delete triggers,
we just should not invoke on update triggers in this case.

CONNECTION_ID() was implemented as a constant Item, i.e. an instance of
Item_static_int_func class holding value computed at creation time.
Since Items are created on parsing, and trigger statements are parsed
on table open, the first connection to open a particular table would
effectively set its own CONNECTION_ID() inside trigger statements for
that table.
Re-implement CONNECTION_ID() as a class derived from Item_int_func, and
compute connection_id on every call to fix_fields().

A table with an on insert trigger was reported as crashed when the insert
was processed with bulk insert mode on (handler::start_bulk_insert).
The trigger was also selecting from the same table, and that caused
the "crash".
The same problem was present when an insert statement, which was processed
in bulk mode, also used a stored function that was reading the same table.
This fix disables bulk inserts if a statement uses functions or invokes
triggers. Implementing more granular checks will require much more code and
therefore can hardly be done in 5.0

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".

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).

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.

unimportant for DROP TABLE (since this statement uses name-locking).

lock type which is specified in table list is unimportant since
name-locking is used.

(This allows us to remove the extra test in check_grant() and check_table_access())
Now when we create or drop trigger we check that both trigger name and trigger
table always have database part specified. Thus we give an error if it they
are not specified explicitly or implicitly via current database.

THD::spcont was non-0 when we were parsing stored routine/trigger

methods of Item_splocal and forced them use wrong runtime context.
Fix ensures that we always have THD::spcont equal to zero during

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.

open_table():
If we are in stored function or trigger we should ensure that

So if we are opening table for writing, we should check that it
is not already open by some calling stamement.
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
#12481: Using NOW() in a stored function breaks statement based replication
#12482: Triggers has side effects with auto_increment values
#11587: trigger causes lost connection error

sql/share/errmsg.txt:

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).

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:

name and not as table name. Adjusted tests properly.
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

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/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.

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

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.
