e855bf33b3 Fixed bug #28898.
For a join query with GROUP BY and/or ORDER BY and a view reference
in the FROM list the metadata erroneously showed empty table aliases
and database names for the view columns.



sql/item.h:
  Fixed bug #28898.
  Body of Item_ref::get_tmp_table_item method has been moved
  to item.cc file.
mysql-test/t/metadata.test:

  to copy pointers to the table alias and database name to the new
  Item_field object created for a field stored in the temporary
  table.
mysql-test/r/metadata.result:

  the Item_ref objects to the new Item_field objects created
  for fields stored in the temporary table.

c0ebdff9c7 Fixed bug #28980: the result of ROUND(<decimal expr>,<int column>)
was erroneously converted to double, while the result of
ROUND(<decimal expr>, <int literal>) was preserved as decimal.
As a result of such a conversion the value of ROUND(D,A) could
differ from the value of ROUND(D,val(A)) if D was a decimal expression.

Now the result of the ROUND function is never converted to 
double if the first argument is decimal.

e164c08eaf Bug #28934: server crash when receiving malformed com_execute packets
Sometimes a parameter slot may not get a value because of the protocol
 data being plain wrong.
 Such cases should be detected and handled by returning an error.
 Fixed by checking data stream constraints where possible (like maximum
 length) and reacting to the case where a value cannot be constructed.

ccf393b67a Bug#28904: INSERT .. ON DUPLICATE was silently updating rows when it shouldn't.
When the INSERT .. ON DUPLICATE KEY UPDATE has to update a matched row but
the new data is the same as in the record then it returns as if
no rows were inserted or updated. Nevertheless the row is silently
updated. This leads to a situation when zero updated rows are reported 
in the case when data has actually been changed.

Now the write_record function updates a row only if new data differs from
that in the record.

2b274a60d5 Bug #28754: RPM builds differ from tar.gz in "ALTER ... RENAME" on views
When constructing the path to the original .frm file ALTER .. RENAME
 was unnecessary (and incorrectly) lowercasing the whole path when not 
 on a case-insensitive filesystem.
 This path should not be modified because of lower_case_table_names
 as it is already in the correct case according to that setting.
 Fixed by removing the lowercasing.
 Unfortunately testing this would require running the tests on a case
 sensitive filesystem in a directory that has uppercase letters.
 This cannot be guaranteed in all setups so no test case added.

d8e2f2622d Fixed bug #28811: crash for a query containing a subquery with
ORDER BY and LIMIT 1. 
The bug was introduced by the patch for bug 21727. The patch
erroneously skipped initialization of the array of headers
for sorted records for non-first evaluations of the subquery.

To fix the problem a new parameter has been added to the
function make_char_array that performs the initialization.
Now this function is called for any invocation of the 
filesort procedure. Yet it allocates the buffer for sorted
records only if this parameter is NULL.

18310fabf4 Bug#28763: Selecting geometry fields in UNION caused server crash.
This bug was introduced by the fix for the bug#27300. In this fix a section
of code was added to the Item::tmp_table_field_from_field_type method.
This section intended to create Field_geom fields for the Item_geometry_func
class and its descendants. In order to get the geometry type of the current
item it casted "this" to the Item_geometry_func* type. But the
Item::tmp_table_field_from_field_type method is also used for creation of
fields for UNION and in this case this method is called for an object of the
Item_type_holder class and the cast to the Item_geometry_func* type causes 
a server crash.

Now the Item::tmp_table_field_from_field_type method correctly works when it's
called for both the Item_type_holder and the Item_geometry_func classes.
The new geometry_type variable is added to the Item_type_holder class.
The new method called get_geometry_type is added to the Item_field
and the Field classes. It returns geometry type from the field for the
Item_field and the Field_geom classes and fails an assert for other Field
descendants.


sql/field.h:
  Bug#28763: Selecting geometry fields in UNION caused server crash.
  The new method called get_geometry_type is added to the Field class.
  It returns geometry type of the field for the Field_geom class
  and fails an assert for other Field descendants.

a temporary table has grown out of heap memory reserved for it and 
the remaining disk space is not big enough to store the table as

8d0d27b5a4 Bug#28505: mysql_affected_rows() may return wrong result if CLIENT_FOUND_ROWS
flag is set.

When the CLIENT_FOUND_ROWS flag is set then the server should return
found number of rows independently whether they were updated or not.
But this wasn't the case for the INSERT statement which always returned
number of rows that were actually changed thus providing wrong info to
the user.

Now the select_insert::send_eof method and the mysql_insert function
are sending the number of touched rows if the CLIENT_FOUND_ROWS flag is set.

0304a13ee7 Bug#28778: Wrong result of BETWEEN when comparing a DATETIME field with an
integer constants.

This bug is introduced by the fix for bug#16377. Before the fix the 
Item_func_between::fix_length_and_dec method converted the second and third
arguments to the type of the first argument if they were constant and the first
argument is of the DATE/DATETIME type. That approach worked well for integer
constants and sometimes produced bad result for string constants. The fix for
the bug#16377 wrongly removed that code at all and as a result of this the
comparison of a DATETIME field and an integer constant was carried out in a
wrong way and sometimes led to wrong result sets.

Now the Item_func_between::fix_length_and_dec method converts the second and
third arguments to the type of the first argument if they are constant, the
first argument is of the DATE/DATETIME type and the DATETIME comparator isn't
applicable.
