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

Bug#18775 - Temporary table from alter table visible to other threads
Manual merge
Continued implementation of WL#1324 (table name to filename encoding)
The intermediate (not temporary) files of the new table
during ALTER TABLE was visible for SHOW TABLES. These
intermediate files are copies of the original table with
the changes done by ALTER TABLE. After all the data is
copied over from the original table, these files are renamed
to the original tables file names. So they are not temporary
files. They persist after ALTER TABLE, but just with another
name.
In 5.0 the intermediate files are invisible for SHOW TABLES
because all file names beginning with "#sql" were suppressed.
This failed since 5.1.6 because even temporary table names were
converted when making file names from them. The prefix became
converted to "@0023sql". Converting the prefix during SHOW TABLES
would suppress the listing of user tables that start with "#sql".
The solution of the problem is to continue the implementation of
the table name to file name conversion feature. One requirement
is to suppress the conversion for temporary table names.
This change is straightforward for real temporary tables as there
is a function that creates temporary file names.
But the generated path names are located in TMPDIR and have no
relation to the internal table name. This cannot be used for
ALTER TABLE. Its intermediate files need to be in the same
directory as the old table files. And it is necessary to be
able to deduce the same path from the same table name repeatedly.
Consequently the intermediate table files must be handled like normal
tables. Their internal names shall start with tmp_file_prefix
(#sql) and they shall not be converted like normal table names.
I added a flags parameter to all relevant functions that are
called from ALTER TABLE. It is used to suppress the conversion
for the intermediate table files.
The outcome is that the suppression of #sql in SHOW TABLES
works again. It does not suppress user tables as these are
converted to @0023sql on file level.
This patch does also fix ALTER TABLE ... RENAME, which could not
rename a table with non-ASCII characters in its name.
It does also fix the problem that a user could create a table like
`#sql-xxxx-yyyy`, where xxxx is mysqld's pid and yyyy is the thread
ID of some other thread, which prevented this thread from running
ALTER TABLE.
Some of the above problems are mentioned in Bug 1405, which can
be closed with this patch.
This patch does also contain some minor fixes for other forgotten
conversions. Still known problems are reported as bugs 21370,
21373, and 21387.

storage/innobase/row/row0mysql.c:
Bug#18775 - Temporary table from alter table visible to other threads
Continued implementation of WL#1324 (table name to filename encoding)
Changed back the encoded temp file prefix to #sql.
Continued implementation of WL#1324 (table name to filename encoding)
The intermediate (not temporary) files of the new table
during ALTER TABLE was visible for SHOW TABLES. These
intermediate files are copies of the original table with
the changes done by ALTER TABLE. After all the data is
copied over from the original table, these files are renamed
to the original tables file names. So they are not temporary
files. They persist after ALTER TABLE, but just with another
name.
In 5.0 the intermediate files are invisible for SHOW TABLES
because all file names beginning with "#sql" were suppressed.
This failed since 5.1.6 because even temporary table names were
converted when making file names from them. The prefix became
converted to "@0023sql". Converting the prefix during SHOW TABLES
would suppress the listing of user tables that start with "#sql".
The solution of the problem is to continue the implementation of
the table name to file name conversion feature. One requirement
is to suppress the conversion for temporary table names.
This change is straightforward for real temporary tables as there
is a function that creates temporary file names.
But the generated path names are located in TMPDIR and have no
relation to the internal table name. This cannot be used for
ALTER TABLE. Its intermediate files need to be in the same
directory as the old table files. And it is necessary to be
able to deduce the same path from the same table name repeatedly.
Consequently the intermediate table files must be handled like normal
tables. Their internal names shall start with tmp_file_prefix
(#sql) and they shall not be converted like normal table names.
I added a flags parameter to all relevant functions that are
called from ALTER TABLE. It is used to suppress the conversion
for the intermediate table files.
The outcome is that the suppression of #sql in SHOW TABLES
works again. It does not suppress user tables as these are
converted to @0023sql on file level.
This patch does also fix ALTER TABLE ... RENAME, which could not
rename a table with non-ASCII characters in its name.
It does also fix the problem that a user could create a table like
`#sql-xxxx-yyyy`, where xxxx is mysqld's pid and yyyy is the thread
ID of some other thread, which prevented this thread from running
ALTER TABLE.
Some of the above problems are mentioned in Bug 1405, which can
be closed with this patch.
This patch does also contain some minor fixes for other forgotten
conversions. Still known problems are reported as bugs 21370,
21373, and 21387.

Now CREATE statements for writing in the binlog are created as follows:
- the beginning of the statement is re-created;
- the rest of the statement is copied from the original query.
The problem appears when there is a version-specific comment (produced by
mysqldump), started in the re-created part of the statement and closed in the
copied part -- there is closing comment-parenthesis, but there is no opening
one.
The proper fix could be to re-create original statement, but we can not
implement it in 5.0. So, for 5.0 the fix is just to cut closing
comment-parenthesis. This technique is also used for SHOW CREATE PROCEDURE
statement (so we are able to reuse existing code).

Routine arguments were evaluated in the security context of the routine

The bug is fixed the following way:
- Item_func_sp::find_and_check_access() has been split into two
functions: Item_func_sp::find_and_check_access() itself only
finds the function and check that the caller have EXECUTE privilege
on it. New function set_routine_security_ctx() changes security
context for SUID routines and checks that definer have EXECUTE
privilege too.
- new function sp_head::execute_trigger() is called from
Table_triggers_list::process_triggers() instead of
sp_head::execute_function(), and is effectively just as the
sp_head::execute_function() is, with all non-trigger related code
removed, and added trigger-specific security context switch.
- call to Item_func_sp::find_and_check_access() stays outside
of sp_head::execute_function(), and there is a code in
sql_parse.cc before the call to sp_head::execute_procedure() that
checks that the caller have EXECUTE privilege, but both
sp_head::execute_function() and sp_head::execute_procedure() call
set_routine_security_ctx() after evaluating their parameters,
and restore the context after the body is executed.

Two main changes:
- We use TABLE::read_set/write_set bitmaps for marking fields used by
statement instead of Field::query_id in 5.1.
- Now when we mark columns used by statement we take into account columns
used by table's triggers instead of marking all columns as used if table
has triggers.
mysql-test/r/federated.result:
Changed test in order to make it work with RBR.
RBR changes the way in which we execute "DELETE FROM t1" statement - we don't
use handler::delete_all_rows() method if RBR is enabled (see bug#19066).
As result federated engine produces different sequences of statements for
remote server in non-RBR and in RBR cases. And this changes order of the
rows inserted by following INSERT statements.

sql/log_event.cc:
Write_rows_log_event::do_before_row_operations():
Now we explicitly inform handler that we want to replace rows so it can
promote operation done by write_row() to replace.
sql/mysql_priv.h:

is no longer used (we have TABLE::mark_columns_needed_for_insert() instead).
sql/sql_insert.cc:
Adjusted code after merge. Get rid of mark_fields_used_by_triggers_for_insert_stmt()
as now we use TABLE::mark_columns_needed_for_insert() for the same purprose.
Aligned places where we call this method with places where we call
mark_fields_used_by_triggers_for_insert() in 5.0.
Finally we no longer need to call handler::extra(HA_EXTRA_WRITE_CAN_REPLACE)
in case of REPLACE statement since in 5.1 write_record() marks all columns
as used before doing actual row replacement.
sql/sql_load.cc:
Adjusted code after merge. In 5.1 we use TABLE::mark_columns_needed_for_insert() instead of
mark_fields_used_by_triggers_for_insert_stmt() routine. We also no longer

NDB table".
SQL-layer was not marking fields which were used in triggers as such. As
result these fields were not always properly retrieved/stored by handler
layer. So one might got wrong values or lost changes in triggers for NDB,
Federated and possibly InnoDB tables.
This fix solves the problem by marking fields used in triggers
appropriately.
Also this patch contains the following cleanup of ha_ndbcluster code:
We no longer rely on reading LEX::sql_command value in handler in order
to determine if we can enable optimization which allows us to handle REPLACE
statement in more efficient way by doing replaces directly in write_row()
method without reporting error to SQL-layer.
Instead we rely on SQL-layer informing us whether this optimization
applicable by calling handler::extra() method with
HA_EXTRA_WRITE_CAN_REPLACE flag.
As result we no longer apply this optimzation in cases when it should not
be used (e.g. if we have on delete triggers on table) and use in some
additional cases when it is applicable (e.g. for LOAD DATA REPLACE).
Finally this patch includes fix for bug#20728 "REPLACE does not work
correctly for NDB table with PK and unique index".
This was yet another problem which was caused by improper field mark-up.
During row replacement fields which weren't explicity used in REPLACE
statement were not marked as fields to be saved (updated) so they have
retained values from old row version. The fix is to mark all table
fields as set for REPLACE statement. Note that in 5.1 we already solve
this problem by notifying handler that it should save values from all
fields only in case when real replacement happens.
include/my_base.h:
Added HA_EXTRA_WRITE_CAN_REPLACE, HA_EXTRA_WRITE_CANNOT_REPLACE - new
parameters for ha_extra() method. We use them to inform handler that
write_row() which tries to insert new row into the table and encounters
some already existing row with same primary/unique key can replace old
row with new row instead of reporting error.

sql/sql_delete.cc:

values for these fields.
sql/sql_insert.cc:
Explicitly inform handler that we are doing REPLACE (using ha_extra() method)
in cases when it can promote insert operation done by write_row() to replace.
Also when we do REPLACE we want to store values for all columns so we should
inform handler about it.
Finally we should mark fields used by ON UPDATE/ON DELETE triggers as such
so handler can properly retrieve/restore values in these fields during
execution of REPLACE and INSERT ... ON DUPLICATE KEY UPDATE statements.
sql/sql_load.cc:
Explicitly inform handler that we are doing LOAD DATA REPLACE (using
ha_extra() method) in cases when it can promote insert operation done by
write_row() to replace.
Also when we do replace we want to save (replace) values for all columns
so we should inform handler about it.
Finally to properly execute LOAD DATA for table with triggers we should
mark fields used by ON INSERT triggers as such so handler can properly
store values for these fields.
sql/sql_parse.cc:
mysql_alter_table() function no longer takes handle_duplicates argument.
sql/sql_table.cc:
Got rid of handle_duplicates argument in mysql_alter_table() and
copy_data_between_tables() functions. These functions were always
called with handle_duplicates == DUP_ERROR and thus contained dead
(and probably incorrect) code.
sql/sql_trigger.cc:
Added Table_triggers_list::mark_fields_used() method which is used to mark
fields read/set by triggers as such so handlers will be able properly
retrieve/store values in these fields.
sql/sql_trigger.h:
Table_triggers_list:
Added mark_fields_used() method which is used to mark fields read/set by
triggers as such so handlers will be able properly retrieve/store values
in these fields. To implement this method added 'trigger_fields' member
which is array of lists linking items for all fields used in triggers
grouped by event and action time.
sql/sql_update.cc:
Mark fields which are used by ON UPDATE triggers so handler will retrieve
and save values for these fields.
mysql-test/r/ndb_trigger.result:
Added test for bug#18437 "Wrong values inserted with a before update trigger
