View definition as SELECT ... FROM DUAL WHERE ... has
valid syntax, but use of such view in SELECT or
SHOW CREATE VIEW syntax causes unexpected syntax error.

Server omits FROM DUAL clause when storing view body
string in a .frm file for further evaluation.
However, syntax of SELECT-witout-FROM query is more
restrictive than SELECT FROM DUAL syntax, and doesn't
allow the WHERE clause.

NOTE: this syntax difference is not documented.


View registration procedure has been modified to
preserve original structure of view's body.

This bug can not be reproduced in the current version,
adding the test case to the test suite for coverage, no code change.

  Minor test case cleanup after bug#34529.

The bool data type was redefined to BOOL (4 bytes on windows).
Removed the #define and fixed some of the warnings that were uncovered
by this.
Note that the fix also disables 2 warnings :
4800 : 'type' : forcing value to bool 'true' or 'false' (performance warning)
4805: 'operation' : unsafe mix of type 'type' and type 'type' in operation

These warnings will be handled in a separate bug, as they are performance related or bogus.

Fixed to int the return type of functions that return more than 
2 distinct values.

When swapping out heap I_S tables to disk, this is done after plan refinement.
Thus, READ_RECORD::file will still point to the (deleted) heap handler at start
of execution. This causes segmentation fault if join buffering is used and the 
query is a star query where the result is found to be empty before accessing
some table. In this case that table has not been initialized (i.e. had its 
READ_RECORD re-initialized) before the cleanup routine tries to close the handler.
Fixed by updating READ_RECORD::file when changing handler.

Before breaking the connection we have to check that there's no query
  executing at the moment. Otherwise it can lead to crash in embedded server.

Queries like:

  SELECT ROW(1, 2) IN (SELECT t1.a, 2)
    FROM t1 GROUP BY t1.a

or 

  SELECT ROW(1, 2) IN (SELECT t1.a, 2 FROM t2)
    FROM t1 GROUP BY t1.a

lead to assertion failure in the
Item_in_subselect::row_value_transformer method in debugging
build, or to unexpected error message in release build:

  ERROR 1247 (42S22): Reference '<list ref>' not supported (forward
                      reference in item list)

Unexpected error message and assertion failure have been
eliminated.

  
Disable test case for bug 29948, which is causing sporadically
failures in other tests inside mysql_client_test.

logging is not enabled on the server.
Fixed by returning error code.

Casting AVG() to DECIMAL led to incorrect results when the arguments
had a non-DECIMAL type, because in this case
Item_sum_avg::val_decimal() performed the division by the number of
arguments twice.

Fixed by changing Item_sum_avg::val_decimal() to not rely on
Item_sum_sum::val_decimal(), i.e. calculate sum and divide using
DECIMAL arithmetics for DECIMAL arguments, and utilize val_real() with
subsequent conversion to DECIMAL otherwise.

Under some circumstances, the mysql_insert_id() value after SELECT ...
INSERT could return a wrong value. This could happen when the last
SELECT ... INSERT did not involve an AUTO_INCREMENT column, but the
value of mysql_insert_id() was changed by some previous statements.

Fixed by checking the value of thd->insert_id_used in
select_insert::send_eof() and returning 0 for mysql_insert_id() if it
is not set.

- Apply Eric Bergen's patch: in join_read_always_key(), move ha_index_init() call
  to before the late NULLs filtering code.
- Backport function comments from 6.0.

                    with errno 17

my_create() did not perform any checks for the case when a file is
successfully created by a call to open(), but the call to
my_register_filename() later fails because the number of open files
has exceeded the my_open_files limit. This can happen on platforms 
which do not have getrlimit(), and hence we do not know the real limit
for open files. In such a case an error was returned to a caller
although the file has actually been created. Since callers assume
my_create() to return an error only when it failed to create a file,
they did not perform any cleanups, leaving an 'orphaned' file on the
file system.

Fixed by adding a check for the above case to my_create() and ensuring
the newly created file is deleted before returning an error.

Creating a deterministic test case in the test suite is impossible,
because the exact steps required to reproduce the above situation
depend on the platform and/or environment (OS per-user limits, queries
executed by previous tests, startup parameters). The patch was
manually tested on Windows using examples posted in the bug report.
