The following were missing in the patch for mwl106:
- KEY_PART_INFO::fieldnr were not set for generated keys to access
tmp tables storing the rows of materialized derived tables/views
- TABLE_SHARE::column_bitmap_size was not set for tmp tables storing
the rows of materialized derived tables/views.
These could cause crashes or memory overwrite.
If a view/derived table is non-mergeable then the definition of the tmp table
to store the rows for it is created at the prepare stage. In this case if the
view definition uses outer joins and a view column belongs to an inner table
of one of them then the column should be considered as nullable independently
on nullability of the underlying column. If the underlying column happens to be
defined as non-nullable then the function create_tmp_field_from_item rather
than the function create_tmp_field_from_field should be employed to create
the definition of the interesting column in the tmp table.
mysql-test/r/join.result:
Test case for LP:798597
mysql-test/t/join.test:
Test case for LP:798597
sql/sql_select.cc:
In simplify_joins we reset table->maybe_null for outer join tables that can't ever be NULL.
This caused a conflict between the previously calculated items and the group_buffer against the fields
in the temporary table that are created as not null thanks to the optimization.
The fix is to correct the group by items to also be not_null so that they match the used fields and keys.
The function simple_pred did not take into account that a multiple equality
could include ref items (more exactly items of the class Item_direct_view_ref).
It caused crashes for queries over derived tables or views if the
min/max optimization could be applied to these queries.
The patch for bugs 717577 and 724942 has missed to make adjustments for the
call item_equal->add_const(const_item, orig_field_item) in the function
check_simple_equality that builds multiple equality for a field and a constant.
As a result, when this field happens to be a view field and the corresponding
Item_field object F is wrapped in an Item_direct_view_ref object R the object
F is placed in the multiple equality instead of the object R.
A substitution of an equal item for F potentially can cause very serious
problems and in some cases can lead to crashes of the server.
- Added regression test with queries over the WORLD database.
- Discovered and fixed several bugs in the related cost calculation
functionality both in the semijoin and non-semijon subquery code.
- Added DBUG printing of the cost variables used to decide between
IN-EXISTS and MATERIALIZATION.
Added option to aria_read_log to crash recovery at certain points in the recovery process.

Align aria_chk -d output
Don't write warning Aria table '...' is usable but should be fixed if the table was before marked as crashed but now is ok
storage/maria/maria_read_log.c:
Added option to aria_read_log to crash recovery at certain points in the recovery process.
The function generate_derived_keys did not take into account the fact
that the last element in the array of keyuses could be just a barrier
element. In some cases it could lead to a crash of the server.
Also fixed a couple of other bugs in generate_derived_keys: the inner
loop in the body of if this function did not change the cycle variables
properly.

INSERT/UPDATE/DELETE statement that used a temptable view v1 could lead to
a crash if v1 was defined as a select from a mergeable view v2 that selected
rows from a temptable view v3.
When INSERT/UPDATE/DELETE uses a view that is not updatable then field
translation for the view should be created before the prepare phase.
The code that added semi-join transformations missed checking
the state of the fixed flag for the items built with the
and_items function before calls of the fix_fields method.
This could lead to an abort failure when the first argument
of and_items() happened to be NULL.
When looking for the execution plan of a derived table to be materialized
JOIN::optimize finds out that all joined tables of the derived table
contain not more than one row then the derived table should be maretialized
at the optimization stage.
Added a test case for the bug.
Adjusted results in other test cases.
compilation error in mysys/my_getsystime.c fixed
some redundant code removed
sec_to_time, time_to_sec, from_unixtime, unix_timestamp, @@timestamp now

Safety check that could cause core dump when doing create table with virtual column.
- Don't attempt to construct FirstMatch access method if we've
just figured three lines above that it can't be used (because join
prefix doesn't have the needed tables), and so have set
pos->first_firstmatch_table= MAX_TABLES
Attempts to analyze join->positions[MAX_TABLES] caused valgrind warnings
