An update that used a join of a table to itself and modified the
table on one side of the join reported the table as crashed or
updated wrong rows.
Fixed by creating temporary table for self-joined multi update statement.
mysql-test/r/myisam.result:
A test case for BUG#21310.
mysql-test/t/myisam.test:
A test case for BUG#21310.
sql/lock.cc:
Exclude 'table' param from check.
sql/sql_update.cc:
Disabling record cache for self-joined multi update statement is wrong.
The join must only see the table as it was at the beginning of the statement.
safe_update_on_fly check if it is safe to update first table on the fly, that is
not creating temporary table. It is possible in case a row from this table is
never read more than once. safe_update_on_fly now detect self-joined table and
refuse to update this table on the fly.
An update that used a join of a table to itself and modified the
table on one side of the join reported the table as crashed or
updated wrong rows.
Fixed by creating temporary table for self-joined multi update statement.

When executing dependent subqueries they are re-inited and re-exec() for
each row of the outer context.
The cause for the bug is that during subquery reinitialization/re-execution,
the optimizer reallocates JOIN::join_tab, JOIN::table in make_simple_join()
and the local variable in 'sortorder' in create_sort_index(), which is
allocated by make_unireg_sortorder().
Care must be taken not to allocate anything into the thread's memory pool
while re-initializing query plan structures between subquery re-executions.
All such items mush be cached and reused because the thread's memory pool
is freed at the end of the whole query.
Note that they must be cached and reused even for queries that are not
otherwise cacheable because otherwise it will grow the thread's memory
pool every time a cacheable query is re-executed.
We provide additional members to the JOIN structure to store references
to the items that need to be cached.

Note: bug#21726 does not directly apply to 4.1, as it doesn't have stored
procedures. However, 4.1 had some bugs that were fixed in 5.0 by the
patch for bug#21726, and this patch is a backport of those fixes.
Namely, in 4.1 it fixes:
- LAST_INSERT_ID(expr) didn't return value of expr (4.1 specific).
- LAST_INSERT_ID() could return the value generated by current
statement if the call happens after the generation, like in
CREATE TABLE t1 (i INT AUTO_INCREMENT PRIMARY KEY, j INT);
INSERT INTO t1 VALUES (NULL, 0), (NULL, LAST_INSERT_ID());
- Redundant binary log LAST_INSERT_ID_EVENTs could be generated.

set THD::last_insert_id_used when statement calls LAST_INSERT_ID().
In Item_func_last_insert_id::val_int(), return THD::current_insert_id
if called like LAST_INSERT_ID(), otherwise return value of argument if
called like LAST_INSERT_ID(expr).
sql/item_func.h:
Add declaration of Item_func_last_insert_id::fix_fields().
sql/log_event.cc:
Do not set THD::last_insert_id_used on LAST_INSERT_ID_EVENT. Though we
know the statement will call LAST_INSERT_ID(), it wasn't called yet.
sql/set_var.cc:
In sys_var_last_insert_id::value_ptr(), set THD::last_insert_id_used,
and return THD::current_insert_id for @@LAST_INSERT_ID.
sql/sql_class.h:

which then will be returned for LAST_INSERT_ID() and @@LAST_INSERT_ID.
sql/sql_select.cc:
If "IS NULL" is replaced with "= <LAST_INSERT_ID>", use right value,
which is THD::current_insert_id, and also set THD::last_insert_id_used
to issue binary log LAST_INSERT_ID_EVENT.

Non-upper-level INSERTs (the ones in the body of stored procedure,
stored function, or trigger) into a table that have AUTO_INCREMENT
column didn't affected the result of LAST_INSERT_ID() on this level.
The problem was introduced with the fix of bug 6880, which in turn was
introduced with the fix of bug 3117, where current insert_id value was
remembered on the first call to LAST_INSERT_ID() (bug 3117) and was
returned from that function until it was reset before the next
_upper-level_ statement (bug 6880).
The fix for bug#21726 brings back the behaviour of version 4.0, and
implements the following: remember insert_id value at the beginning
of the statement or expression (which at that point equals to
the first insert_id value generated by the previous statement), and
return that remembered value from LAST_INSERT_ID() or @@LAST_INSERT_ID.
Thus, the value returned by LAST_INSERT_ID() is not affected by values
generated by current statement, nor by LAST_INSERT_ID(expr) calls in
this statement.
Version 5.1 does not have this bug (it was fixed by WL 3146).

Item_func_last_insert_id::val_int().

THD::current_insert_id the first value generated during execution of the
previous statement, and return this value for @@LAST_INSERT_ID.
sql/sql_class.cc:
Reset THD::last_insert_id_used after each statement execution.
sql/sql_class.h:
Rather then remember current insert_id value on first invocation of
THD::insert_id(), remember it in Item_func_last_insert_id::fix_fields(),
sys_var_last_insert_id::value_ptr(), or mysql_execute_command().
Remove THD::insert_id(), as it lost its value now.
sql/sql_insert.cc:
THD::insert_id() is removed, use THD::last_insert_id directly.
sql/sql_load.cc:
THD::insert_id() is removed, using THD::last_insert_id directly is OK.
sql/sql_parse.cc:
Remember in THD::current_insert_id first generated insert id value of
the previous statement in mysql_execute_command().
No need to reset THD::last_insert_id_used in
mysql_reset_thd_for_next_command(), it will be reset after each
statement.
sql/sql_select.cc:

this key does not stop" (5.1 version).
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 with help of
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. We do this by
changing check_if_key_used() to take field bitmap instead
field list as argument and passing TABLE::write_set
to it (we also have to add info about fields used in
triggers to this bitmap a bit earlier).
As nice side-effect we have more precise and thus more optimal
perfomance-wise check for the MULTI-UPDATE.
Also check_if_key_used() routine and similar method were renamed
to is_key_used()/is_keys_used() in order to better reflect that
it is simple boolean predicate.
Finally, partition_key_modified() routine now also takes field
bitmap instead of field list as argument.
sql/key.cc:
Now check_if_key_used() takes field bitmap instead of field list as
argument (bitmaps are also used in its implementation).
It is no longer responsible for checking if key uses automatically
updated TIMESTAMP fields, instead callers should properly mark such
fields in field bitmap.
Also renamed this function to is_key_used().
sql/mysql_priv.h:
Renamed check_if_key_used() to is_key_used(), also now this routine
takes field bitmap instead of field list as argument.
sql/opt_range.cc:
QUICK_SELECT_I::check_if_keys_used() method and check_if_key_used()
routine were renamed to is_keys_used()/is_key_used(). Also now they

sql/sql_update.cc:
To detect situation in which trigger modifies part of key which is
going to be used for processing of where clause and thus makes
processing of this update with update-on-the-fly method unsafe
we use check_if_key_used() routine and similar method (which were
renamed to is_key_used()) plus information from TABLE::write_map
bitmap. Note that we have to call TABLE::mark_columns_needed_for_update()
method earlier now to fill this bitmap with information about fields
updated in triggers.
safe_update_on_fly() routine now uses the same approach and no
longer needs list of fields as argument.

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
mysql-test/r/trigger.result:
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.
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.
