b444f80882 Fix for BUG#24040: Create View don't succed with "all privileges"
on a database.

The problem was that we required not less privileges on the base tables
than we have on the view.

The fix is to be more flexible and allow to create such a view (necessary
privileges will be checked at the runtime).


mysql-test/r/view_grant.result:
  Updated result file.
mysql-test/t/view_grant.test:
  Added test case for BUG#24040 (Create View don't succed with
  "all privileges" on a database).

6d93f15039 Bug#27006: AFTER UPDATE triggers not fired with INSERT ... ON DUPLICATE KEY
UPDATE if the row wasn't actually changed.

This bug was caused by fix for bug#19978. It causes AFTER UPDATE triggers
not firing if a row wasn't actually changed by the update part of the
INSERT .. ON DUPLICATE KEY UPDATE.

Now triggers are always fired if a row is touched by the INSERT ... ON
DUPLICATE KEY UPDATE.

2e8e78a42c Bug #26261:
INSERT uses query_id to verify what fields are
 mentioned in the fields list of the INSERT command.
 However the check for that is made after the 
 ON DUPLICATE KEY is processed. This causes all
 the fields mentioned in ON DUPLICATE KEY to be 
 considered as mentioned in the fields list of 
 INSERT.
 Moved the check up, right after processing the
 fields list.

542f18a31a Bug#27033: 0 as LAST_INSERT_ID() after INSERT .. ON DUPLICATE if rows were
touched but not actually changed.

The LAST_INSERT_ID() is reset to 0 if no rows were inserted or changed.
This is the case when an INSERT ... ON DUPLICATE KEY UPDATE updates a row
with the same values as the row contains.

Now the LAST_INSERT_ID() values is reset to 0 only if there were no rows
successfully inserted or touched.
The new 'touched' field is added to the COPY_INFO structure. It holds the
number of rows that were touched no matter whether they were actually
changed or not.

a22f257e04 Bug #26794:
Different set of conditions is used to verify
the validity of index definitions over a GEOMETRY
column in ALTER TABLE and CREATE TABLE. 
The difference was on how sub-keys notion validity
is checked.
Fixed by extending the CREATE TABLE condition to
support the cases allowed in ALTER TABLE.
Made the SHOW CREATE TABLE not to display spatial
indexes using the sub-key notion.

969b71653d BUG#26881 - Large MERGE tables report incorrect specification when no
differences in tables
Certain merge tables were wrongly reported as having incorrect definition:
- Some fields that are 1 byte long (e.g. TINYINT, CHAR(1)), might
  be internally casted (in certain cases) to a different type on a
  storage engine layer. (affects 4.1 and up)
- If tables in a merge (and a MERGE table itself) had short VARCHAR column (less
  than 4 bytes) and at least one (but not all) tables were ALTER'ed (even to an
  identical table: ALTER TABLE xxx ENGINE=yyy), table definitions went ouf of
  sync. (affects 4.1 only)

This is fixed by relaxing a check for underlying conformance and setting
field type to FIELD_TYPE_STRING in case varchar is shorter than 4
when a table is created.


myisam/mi_create.c:
  Added a comment.
mysql-test/r/merge.result:
  A test case for bug#26881.
mysql-test/t/merge.test:
  A test case for bug#26881.
sql/ha_myisam.cc:
  Relaxed some checks performed by check_definition():
  As comparing of fulltext keys (and key segments) is not yet implemented,
  only return an error in case one of keys is fulltext and other is not.
  Otherwise, if both keys are fulltext, accept them as is.
  
  As comparing of spatial keys (and key segments) is not yet implemented,
  only return an error in case one of keys is spatial and other is not.
  Otherwise, if both keys are spatial, accept them as is.
  
  A workaround to handle situation when field is casted from FIELD_SKIP_ZERO
  to FIELD_NORMAL. This could happen only in case field length is 1 and row
  format is fixed.
sql/sql_parse.cc:
  When a table that has varchar field shorter than 4 is created, field type is
  set to FIELD_TYPE_VAR_STRING. Later, when a table is modified using alter
  table, field type is changed to FIELD_TYPE_STRING (see Field_string::type).
  That means HA_OPTION_PACK_RECORD flag might be lost and thus null_bit might
  be shifted by alter table, in other words alter table doesn't create 100%
  equal table definition.
  
  This is usually not a problem, since when a table is created/altered,
  definition on a storage engine layer is based on one that is passed from
  sql layer. But it is a problem for merge engine - null_bit is shifted when
  a table (merge or underlying) is altered.
  
  Set field type to FIELD_TYPE_STRING in case FIELD_TYPE_VAR_STRING is shorter
  than 4 when a table is created as it is done in Field::type.

91abf15ed2 Fixed bug #26738: incomplete string values in a result set column
when the column is to be read from a derived table column which 
was specified as a concatenation of string literals.
The bug happened because the Item_string::append did not adjust the
value of Item_string::max_length. As a result of it the temporary 
table column  defined to store the concatenation of literals was 
not wide enough to hold the whole value.

816ea8a379 Bug#15757: Wrong SUBSTRING() result when a tmp table was employed.
When the SUBSTRING() function was used over a LONGTEXT field the max_length of
the SUBSTRING() result was wrongly calculated and set to 0. As the max_length
parameter is used while tmp field creation it limits the length of the result
field and leads to printing an empty string instead of the correct result.

Now the Item_func_substr::fix_length_and_dec() function correctly calculates
the max_length parameter.

548a39a104 Bug#25673 - spatial index corruption, error 126
incorrect key file for table

In certain cases it could happen that deleting a row could
corrupt an RTREE index.

According to Guttman's algorithm, page underflow is handled
by storing the page in a list for later re-insertion. The
keys from the stored pages have to be inserted into the
remaining pages of the same level of the tree. Hence the
level number is stored in the re-insertion list together
with the page.

In the MySQL RTree implementation the level counts from zero
at the root page, increasing numbers for levels down the tree.

If during re-insertion of the keys the tree height grows, all
level numbers become invalid. The remaining keys will be
inserted at the wrong level.

The fix is to increment the level numbers stored in the
reinsert list after a split of the root block during reinsertion.

  stored in the reinsert list after a split of the root block
  during reinsertion.

11b533b8be Bug#25373: Stored functions wasn't compared correctly which leads to a wrong
result.

For built-in functions like sqrt() function names are hard-coded and can be
compared by pointer. But this isn't the case for a used-defined stored
functions - names there are dynamical and should be compared as strings.

Now the Item_func::eq() function employs my_strcasecmp() function to compare
used-defined stored functions names.

6de277910b Bug#22331: Wrong WHERE in EXPLAIN EXTENDED when all expressions were optimized
away.

During optimization stage the WHERE conditions can be changed or even
be removed at all if they know for sure to be true of false. Thus they aren't
showed in the EXPLAIN EXTENDED which prints conditions after optimization.

Now if all elements of an Item_cond were removed this Item_cond is substituted
for an Item_int with the int value of the Item_cond.
If there were conditions that were totally optimized away then values of the
saved cond_value and having_value will be printed instead.
