1d24597ff9 Bug#25452 mysql_upgrade access denied
- Improve mysql_upgrade and add comments describing it's logic
 - Don't look for mysql and mysqlcheck randomly, use dir where mysql_upgrade
  was started from
 - Don't look for mysql_fix_privilege_tables.sql randomly, compile
  in the mysql_fix_privilege_tables.sql file and use that to upgrade
  the system tables of MySQL
 - Check for any unexpected error returned from runnning the mysql_fix_privilege_tables SQL
 - Fix bug#26639, bug#24248 and bug#25405

2efc0f51cf Bug #26242 UPDATE with subquery and triggers failing with cluster tables
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.

7e08016a91 Fix for BUG#27337: Privileges are not properly restored.
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.

    - 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.

6a594ffd18 Fix for BUG#25082: default database change on trigger
execution breaks replication.

When a stored routine is executed, we switch current
database to the database, in which the routine
has been created. When the stored routine finishes,
we switch back to the original database.

The problem was that if the original database does not
exist (anymore) after routine execution, we raised an error.

The fix is to report a warning, and switch to the NULL database.

6da758c216 Fixed bug #26560.
The flag alias_name_used was not set on for the outer references
in subqueries. It resulted in replacement of any outer reference
resolved against an alias for a full field name when the frm 
representation of a view with a subquery was generated. 
If the subquery and the outer query referenced the same table in
their from lists this replacement effectively changed the meaning
of the view and led to wrong results for selects from this view. 

Modified several functions to ensure setting the right value of
the alias_name_used flag for outer references resolved against
aliases.
 


mysql-test/r/view.result:
  Added a test case for bug #26560.
mysql-test/t/view.test:
  Added a test case for bug #26560.
sql/item.cc:
  Fixed bug #26560.
  Made the function resolve_ref_in_select_and_group analyze the return
  value of the last parameter with the type of the name resolution for
  the submitted reference. If the reference has been resolved against 
  an alias name from select list then its flag alias_name_used is set on.
  Now this value is used in Item_field::fix_outer_field to initialize the flag
  when the item_ref object is created for an outer reference.
  Added a parameter for the second Item_ref::Item_ref constructor to initialize
  properly the flag alias_name_used. The default value of the parameter is FALSE.
  If this flag is set on at the creation of an object by this constructor it
  will never be changed. Corrected appropriately the Item_ref::set_properties
  function.
  The function Item_ref::print now prints alias name for an outer reference
  if the flag alias_name_used is set on.
sql/item.h:
  Fixed bug #26560.
  Added a parameter for the second Item_ref::Item_ref constructor to initialize
  properly the flag alias_name_used. The default value of the parameter is FALSE.
  A similar change has been applied to the first Item_direct_ref::Item_direct_ref
  constructor.
sql/mysql_priv.h:
  Fixed bug #26560.
  Added an an enumeration type enum_resolution_type to return info on
  how the function find_item_in_list has resolved the submitted item.
  The type is used only for this function.
sql/sql_base.cc:
  Fixed bug #26560.
  Made the last parameter of the function find_field_in_tables return
  more detailed information on how the submitted item has been resolved.
  Now it says whether the item has been resolved
    against an alias name,
    or as a field name without alias,
    or as a field name hidden by alias, 
    or was resolved ignoring alias.
sql/sql_select.cc:
  Fixed bug #26560.
  Took into account the new type of the last parameter of the function
  find_item_in_list.

f8855142d7 Bug#23800: Outer fields in correlated subqueries is used in a temporary table
created for sorting.

Any outer reference in a subquery was represented by an Item_field object.
If the outer select employs a temporary table all such fields should be
replaced with fields from that temporary table in order to point to the 
actual data. This replacement wasn't done and that resulted in a wrong
subquery evaluation and a wrong result of the whole query.

Now any outer field is represented by two objects - Item_field placed in the
outer select and Item_outer_ref in the subquery. Item_field object is
processed as a normal field and the reference to it is saved in the
ref_pointer_array. Thus the Item_outer_ref is always references the correct
field. The original field is substituted for a reference in the
Item_field::fix_outer_field() function.

New function called fix_inner_refs() is added to fix fields referenced from
inner selects and to fix references (Item_ref objects) to these fields.

The new Item_outer_ref class is a descendant of the Item_direct_ref class.
It additionally stores a reference to the original field and designed to
behave more like a field.


sql/item.cc:
  Bug#23800: Correlated sub query returning incorrect results when operated upon.

  in the Item_field::fix_outer_field() function.

2572c82621 Bug#24630 Subselect query crashes mysqld
The crash happens because second filling of the same I_S table happens in
case of subselect with order by. table->sort.io_cache previously allocated
in create_sort_index() is deleted during second filling
(function get_schema_tables_result). There are two places where
I_S table can be filled: JOIN::exec and create_sort_index().
To fix the bug we should check if the table was already filled
in one of these places and skip processing of the table in second.

fbc16a85c2 BUG#25575: ERROR 1052 (Column in from clause is ambiguous) with sub-join
Two problems here:

 Problem 1:

 While constructing the join columns list the optimizer does as follows:
  1. Sets the join_using_fields/natural_join members of the right JOIN 
   operand.
  2. Makes a "table reference" (TABLE_LIST) to parent the two tables.
  3. Assigns the join_using_fields/is_natural_join of the wrapper table
   using join_using_fields/natural_join of the rightmost table
  4. Sets join_using_fields to NULL for the right JOIN operand.
  5. Passes the parent table up to the same procedure on the upper 
   level.

 Step 1 overrides the the join_using_fields that are set for a nested 
 join wrapping table in step 4.
 Fixed by making a designated variable SELECT_LEX::prev_join_using to 
 pass the data from step 1 to step 4 without destroying the wrapping 
 table data.

 Problem 2:

 The optimizer checks for ambiguous columns while transforming 
 NATURAL JOIN/JOIN USING to JOIN ON. While doing that there was no
 distinction between columns that are used in the generated join
 condition (where ambiguity can be checked) and the other columns
 (where ambiguity can be checked only when resolving references
 coming from outside the JOIN construct itself).
 Fixed by allowing the non-USING columns to be present in multiple 
 copies in both sides of the join and moving the ambiguity check 
 to the place where unqualified references to the join columns are
 resolved (find_field_in_natural_join()).

faad73550c fix for bug #19690: ORDER BY eliminates rows from the result
Depending on the queries we use different data processing methods
and can lose some data in case of double (and decimal in 4.1) fields.

The fix consists of two parts:
1. double comparison changed, now double a is equal to double b 
if (a-b) is less than 5*0.1^(1 + max(a->decimals, b->decimals)). 
For example, if a->decimals==1, b->decimals==2, a==b if (a-b)<0.005
2. if we use a temporary table, store double values there as is 
to avoid any data conversion (rounding).

  fix for bug #19690: ORDER BY eliminates rows from the result
    - test case
sql/field.cc:
  fix for bug #19690: ORDER BY eliminates rows from the result
    - use not_fixed flag instead of dec to check bounds.
sql/field.h:
  fix for bug #19690: ORDER BY eliminates rows from the result
    - Field_Double::not_fixed flag introduced, which is set if dec == NOT_FIXED_DEC
      and is used in the ::store() to check bounds. 
    - new constructor introduced (with not_fixed_arg parameter).
sql/init.cc:
  fix for bug #19690: ORDER BY eliminates rows from the result
    - fill log_01[] array with 0.1 powers.
sql/item_cmpfunc.cc:
  fix for bug #19690: ORDER BY eliminates rows from the result
    - compare_real_fixed() and compare_e_real_fixed() introduced,
      they consider double a == double b if a-b is less than 'precision',
      'precision' is set to 5*0.1^(1 + max(a->decimals, b->decimals)), 
      for example, if a->decimals==1, b->decimals==2, 'precision' is 0.005
    - use the above functions if both arguments are fixed.
sql/item_cmpfunc.h:
  fix for bug #19690: ORDER BY eliminates rows from the result
    - Arg_comparator::presision introduced.
    - Arg_comparator::compare_real_fixed(), Arg_comparator::compare_e_real_fixed() introduced.
sql/mysql_priv.h:
  fix for bug #19690: ORDER BY eliminates rows from the result
    - log_01 array of 0.1 powers added.
sql/mysqld.cc:
  fix for bug #19690: ORDER BY eliminates rows from the result
    - log_01 array of 0.1 powers added.
sql/sql_select.cc:
  fix for bug #19690: ORDER BY eliminates rows from the result
    - if we create double field in a temporary table, set not_fixed flag
      (use proper constructor) to avoid data conversion 
      in the Field_double::store(). Otherwise we can lose some data.
