Two functions have different ideas of what a string should look like;
one of them reads memory it assumes the other one may have written.
And "if you assume ..."
We now use a more defensive variety of the assuming function, this fixes
a warning thrown by the valgrind tool.
sql/item_cmpfunc.cc:
c_ptr() makes incorrect assumptions about the string we get from
out of args[0]->val_str(&tmp); c_str_safe() is more defensive.

The bug was fixed similar to how context switch is handled in
Item_func_sp::execute_impl(): we store pointer to current
Name_resolution_context in Item_func_current_user class, and use
its Security_context in Item_func_current_user::fix_fields().
mysql-test/r/view_grant.result:
Add result for bug#20570.

sql/item_create.cc:
Remove create_func_current_user(), as it is not used for automatic
function creation.
sql/item_create.h:
Remove prototype for create_func_current_user().
sql/item_strfunc.cc:
Add implementations for Item_func_user::init(),
Item_func_user::fix_fields() and
Item_func_current_user::fix_fields() methods. The latter uses
Security_context from current Name_resolution_context, if one is
defined.
sql/item_strfunc.h:
Move implementation of CURRENT_USER() out of Item_func_user to
to new Item_func_current_user class. For both classes calculate
user name in fix_fields() method.
For Item_func_current_user add context field to store
Name_resolution_context in effect.
sql/sql_yacc.yy:
Pass current Name_resolution_context to Item_func_current_user.
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.
mysql-test/r/federated.result:
Additional test for bug#18437 "Wrong values inserted with a before update

sql/item.cc:
Item_trigger_field::setup_field():
Added comment explaining why we don't set Field::query_id in this method.
sql/mysql_priv.h:
mysql_alter_table() function no longer takes handle_duplicates argument.
Added declaration of mark_fields_used_by_triggers_for_insert_stmt() function.
sql/sql_delete.cc:
Mark fields which are used by ON DELETE triggers so handler will retrieve
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.

The intention with the original code was to show that MySQL treats the first
given unique key as a primary key. Clients can use the marked primary key as a
real primary key to validate row changes in case of conflicting updates. The
ODBC driver (and other drivers) may also use this fact to optimize/check
updates and handle conflicts. The marked key also shows what some engines, like InnoDB or NDB,
will use as it's internal primary key.
For checking if someone has declared a true PRIMARY KEY, one should use 'SHOW CREATE TABLE'

When using a parameter bind MYSQL_TYPE_DATE in a prepared statement,
the time part of the MYSQL_TIME buffer was written to zero in

In some functions dealing with strings and character sets, the wrong
