in a select list.
The objects of the Item_trigger_field class inherited the implementations
of the methods copy_or_same, get_tmp_table_item and get_tmp_table_field
from the class Item_field while they rather should have used the default
implementations defined for the base class Item.
It could cause catastrophic problems for triggers that used SELECTs
with select list containing trigger fields such as NEW.<table column>
under DISTINCT.

This is the 5.0 part of the fix.
Currently TRUNCATE command will not call
delete_all_rows() in the handler (that implements
the "fast" TRUNCATE for InnoDB) when there are
triggers on the table.
As decided by the architecture team TRUNCATE must
use "fast" TRUNCATE even when there are triggers.
Thus it must ignore the triggers.
Made TRUNCATE to ignore the triggers and call
delete_all_rows() for all storage engines
to maintain engine consistency.

mysql-test/t/trigger.test:

sql/sql_delete.cc:
Bug#23556: TRUNCATE TABLE still maps to DELETE
- We implemenent fast TRUNCATE for InnoDB even
if triggers are present.
- TRUNCATE ignores triggers.
This change set implements the DROP TRIGGER IF EXISTS functionality.
This fix is considered a bug and not a feature, because without it,
there is no known method to write a database creation script that can create
a trigger without failing, when executed on a database that may or may not
contain already a trigger of the same name.
Implementing this functionality closes an orthogonality gap between triggers
and stored procedures / stored functions (which do support the DROP IF
EXISTS syntax).
In sql_trigger.cc, in mysql_create_or_drop_trigger,
the code has been reordered to:
- perform the tests that do not depend on the file system (access()),
- get the locks (wait_if_global_read_lock, LOCK_open)
- call access()
- perform the operation
- write to the binlog
- unlock (LOCK_open, start_waiting_global_read_lock)
This is to ensure that all the code that depends on the presence of the
trigger file is executed in the same critical section,
and prevents race conditions similar to the case fixed by Bug 14262 :
- thread 1 executes DROP TRIGGER IF EXISTS, access() returns a failure
- thread 2 executes CREATE TRIGGER
- thread 2 logs CREATE TRIGGER
- thread 1 logs DROP TRIGGER IF EXISTS

stored function invoked from different connections".
Invocation of trigger which was using stored function from different
connections caused server crashes (for non-debug server this happened
in highly concurrent environment, but debug server failed on assertion
in relatively simple scenario).
Item_func_sp was not safe to use in triggers (in other words for
re-execution from different threads) as artificial TABLE object
pointed by Item_func_sp::dummy_table referenced incorrect THD
object. To fix the problem we force re-initialization of this
object for each re-execution of statement.

This patch reverts a change introduced by Bug 6951, which incorrectly
set thd->abort_on_warning for stored procedures.
As per internal discussions about the SQL_MODE=TRADITIONAL,
the correct behavior is to *not* abort on warnings even inside an INSERT/UPDATE
trigger.
Tests for Stored Procedures, Stored Functions, Triggers involving SQL_MODE
have been included or revised, to reflect the intended behavior.
(reposting approved patch, to work around source control issues, no review needed)

this key does not stop" (version for 5.0 only).
UPDATE statement which WHERE clause used key and which invoked trigger
that modified field in this key worked indefinetely.
This problem occured because in cases when UPDATE statement was
executed in update-on-the-fly mode (in which row is updated right
during evaluation of select for WHERE clause) the new version of
the row became visible to select representing WHERE clause and was
updated again and again.
We already solve this problem for UPDATE statements which does not
invoke triggers by detecting the fact that we are going to update
field in key used for scanning and performing update in two steps,
during the first step we gather information about the rows to be
updated and then doing actual updates. We also do this for
MULTI-UPDATE and in its case we even detect situation when such
fields are updated in triggers (actually we simply assume that
we always update fields used in key if we have before update
trigger).
The fix simply extends this check which is done in check_if_key_used()/
QUICK_SELECT_I::check_if_keys_used() routine/method in such way that
it also detects cases when field used in key is updated in trigger.
As nice side-effect we have more precise and thus more optimal
perfomance-wise check for the MULTI-UPDATE.
Also check_if_key_used()/QUICK_SELECT_I::check_if_keys_used() were
renamed to is_key_used()/QUICK_SELECT_I::is_keys_used() in order to
better reflect that boolean predicate.
Note that this check is implemented in much more elegant way in 5.1

Added test case for bug#20670 "UPDATE using key and invoking trigger that
modifies this key does not stop".
mysql-test/t/trigger.test:
Added test case for bug#20670 "UPDATE using key and invoking trigger that
modifies this key does not stop".
sql/key.cc:
Renamed check_if_key_used() to is_key_used(). Also this routine checks if
key uses field which can be updated by before update trigger defined on the
table. As result we avoid using update-on-the-fly method in cases when trigger
updates part of key which is used by select which filters rows to be updated
and thus avoid infinite updates. By doing such check here we cover both UPDATE
and MULTI-UPDATE cases.
sql/mysql_priv.h:
Renamed check_if_key_used() to is_key_used().
sql/opt_range.cc:
Renamed check_if_key_used()/QUICK_SELECT_I::check_if_keys_used() to
is_key_used()/QUICK_SELECT_I::is_keys_used().
sql/opt_range.h:
Renamed QUICK_SELECT_I::check_if_keys_used() method to is_keys_used(),
also updated comment describing it to reflect its extended semantics
(this change was caused by change in check_if_key_used()/is_key_used()
routine semantics).
sql/sql_trigger.cc:
Introduced Table_triggers_list::is_updated_in_before_update_triggers()
method which is needed for checking if field of subject table can be
changed in before update trigger.
sql/sql_trigger.h:
Table_triggers_list:
Removed has_before_update_triggers() method which is not used any longer.
Added declaration of is_updated_in_before_update_triggers() which is
needed for checking if field of subject table can be changed by before
update trigger.
sql/sql_update.cc:
safe_update_on_fly():
check_if_key_used() routine and check_if_keys_used() method were
renamed to is_key_used()/is_keys_used().
Now cases when trigger updates fields which are part of key used for
filtering rows for update are caught directly in is_key_used().
This also allows to cover both UPDATE and MULTI-UPDATE cases.

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/sp-error.result:

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:
Added test for values returned by ROW_COUNT() function (and thus for values

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.

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

Applying ALTER/OPTIMIZE/REPAIR TABLE statements to transactional table or to

Removal of strdup() which is no longer necessary allows us to preserve

since it can be also true when we do "ALTER TABLE t1 RENAME TO t1".

"Rename table does not keep info of triggers".
The bug was caused by the fact that during reconstruction of CREATE TRIGGER

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

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.
