In certain cases AFTER UPDATE/DELETE triggers on NDB tables that referenced
subject table didn't see the results of operation which caused invocation
of those triggers. In other words AFTER trigger invoked as result of update
(or deletion) of particular row saw version of this row before update (or
deletion).
The problem occured because NDB handler in those cases postponed actual
update/delete operations to be able to perform them later as one batch.
This fix solves the problem by disabling this optimization for particular
operation if subject table has AFTER trigger for this operation defined.
To achieve this we introduce two new flags for handler::extra() method:
HA_EXTRA_DELETE_CANNOT_BATCH and HA_EXTRA_UPDATE_CANNOT_BATCH.
These are called if there exists AFTER DELETE/UPDATE triggers during a
statement that potentially can generate calls to delete_row()/update_row().
This includes multi_delete/multi_update statements as well as insert statements
that do delete/update as part of an ON DUPLICATE statement.
include/my_base.h:
Added HA_EXTRA_DELETE_CANNOT_BATCH and HA_EXTRA_UPDATE_CANNOT_BATCH to inform handler when batching of delete/update is not possible.
mysql-test/r/ndb_trigger.result:
Bug #26242 UPDATE with subquery and triggers failing with cluster tables
---
Added new test cases
mysql-test/t/ndb_trigger.test:
Bug #26242 UPDATE with subquery and triggers failing with cluster tables
---
Added new test cases
sql/ha_ndbcluster.cc:
Bug #26242 UPDATE with subquery and triggers failing with cluster tables: Use HA_EXTRA_DELETE_CANNOT_BATCH and HA_EXTRA_UPDATE_CANNOT_BATCH to inform handler when batching of delete/update is not possible
sql/ha_ndbcluster.h:
Bug #26242 UPDATE with subquery and triggers failing with cluster tables: Added member variables for handling of HA_EXTRA_DELETE_CANNOT_BATCH and HA_EXTRA_UPDATE_CANNOT_BATCH to inform handler when batching of delete/update is not possible
sql/mysql_priv.h:
Added new method prepare_triggers_for_insert_stmt to check if batching of delete/update must be disallowed.
sql/sql_delete.cc:
Use HA_EXTRA_DELETE_CANNOT_BATCH to inform handler when batching of delete is not possible
sql/sql_insert.cc:
Added method prepare_triggers_for_insert_stmt to check if batching of delete/update must be dissallowed.
Use HA_EXTRA_DELETE_CANNOT_BATCH and HA_EXTRA_UPDATE_CANNOT_BATCH to inform handler
when batching of delete/update is not possible
sql/sql_load.cc:
Call prepare_triggers_for_insert_stmt to check if batching of delete/update must be dissallowed and
mark fields used by triggers for the insert statement.
sql/sql_trigger.h:
Added has_triggers to support what particular triggers exist on a table.
sql/sql_update.cc:
Use HA_EXTRA_UPDATE_CANNOT_BATCH to inform handler when batching of update is not possible
IN/BETWEEN predicates in sorting expressions.
Wrong results may occur when the select list contains an expression
with IN/BETWEEN predicate that differs from a sorting expression by
an additional NOT only.
Added the method Item_func_opt_neg::eq to compare correctly expressions
containing [NOT] IN/BETWEEN.
The eq method inherited from the Item_func returns TRUE when comparing
'a IN (1,2)' with 'a NOT IN (1,2)' that is not, of course, correct.
mysql-test/r/order_by.result:
Added a test case for bug #27532.
mysql-test/t/order_by.test:
Added a test case for bug #27532.
sql/item_cmpfunc.cc:
Fixed bug #27532.
Added the method Item_func_opt_neg::eq to compare correctly expressions
containing [NOT] IN/BETWEEN.
The eq method inherited from the Item_func returns TRUE when comparing
'a IN (1,2)' with 'a NOT IN (1,2)' that is not, of course, correct.
sql/item_cmpfunc.h:
Added the method Item_func_opt_neg::eq to compare correctly expressions
containing [NOT] IN/BETWEEN.
The eq method inherited from the Item_func returns TRUE when comparing
'a IN (1,2)' with 'a NOT IN (1,2)' that is not, of course, correct.

The problem was that THD::db_access variable was not restored after
database switch in stored-routine-execution code.
The fix is to restore THD::db_access in this case.
Unfortunately, this fix requires additional changes,
because in prepare_schema_table(), called on the parsing stage, we checked
privileges. That was wrong according to our design, but this flaw haven't
struck so far, because it was masked. All privilege checkings must be
done on the execution stage in order to be compatible with prepared statements
and stored routines. So, this patch also contains patch for
prepare_schema_table(), which moves the checkings to the execution phase.
mysql-test/r/grant.result:
Updated result file.
mysql-test/t/grant.test:
Added test case for BUG#27337.
sql/mysql_priv.h:
Added function declaration.
sql/sql_db.cc:
Fix for BUG#27337 -- set THD::db_access even if we're called
from stored-routine-execution code.
sql/sql_parse.cc:
Split prepare_schema_table() into two functions:
- prepare_schema_table(), which is called from the parser (parsing stage);
- check_show_access(), which is called on the execution stage.
sql/sql_show.cc:
Ignore schema_select_lex member if its table is NULL.
mysql-test/r/ndb_autodiscover.result:
changes ndbd error code to mysqld error code when no cluster connection
sql/ha_ndbcluster.cc:
map 4009 error code to mysql not connected error
sql/handler.cc:
define return codes to ha_table_exists_in_engine to something useful
NOTE: in 5.1 this should call a handlerton method, not horrible ifdef ndb stuff
sql/sql_table.cc:
clearly define what happens on create table if exits/not exists/not connected to engine
The query-cache watch thread was continually allocating new thread entries on the
THD MEM_ROOT, not freed until server exit.
Fixed by using a simple array, auto-expanded as necessary.
sql/ha_ndbcluster.cc:
Use a fixed array (auto-expanded as necessary) for temporary copy of open shares,
don't keep pushing list entries on the THD mem root.
LEFT JOIN
Fixed that in certain situations MATCH ... AGAINST returns false hits
for NULLs produced by LEFT JOIN when there is no fulltext index
available.
mysql-test/r/fulltext_left_join.result:
A test case for BUG#25729.
mysql-test/t/fulltext_left_join.test:
A test case for BUG#25729.
sql/item_func.cc:
concat_ws(NULL) returns empty string instead of NULL. There is not much
sense to calculate relevance for empty strings, thus return 0 immediately
if we got NULL or empty string from concat_ws.
sql/item_func.h:
Item_func_match::concat renamed to concat_ws.
