the loose scan optimization for grouping queries was applied returned 
a wrong result set when the query was used with the SQL_BIG_RESULT
option.

The SQL_BIG_RESULT option forces to use sorting algorithm for grouping
queries instead of employing a suitable index. The current loose scan
optimization is applied only for one table queries when the suitable
index is covering. It does not make sense to use sort algorithm in this
case. However the create_sort_index function does not take into account
the possible choice of the loose scan to implement the DISTINCT operator
which makes sorting unnecessary. Moreover the current implementation of
the loose scan for queries with distinct assumes that sorting will
never happen. Thus in this case create_sort_index should not call
the function filesort.

The C optimizer may decide that data access operations
through pointer of different type are not related to 
the original data (strict aliasing).
This is what happens in fetch_long_with_conversion(),
when called as part of mysql_stmt_fetch() : it tries 
to check for truncation errors by first storing float
(and other types of data) into a char * buffer and then 
accesses them through a float pointer.
This is done to prevent the effects of excess precision
when using FPU registers.
However the doublestore() macro converts a double pointer
to an union pointer. This violates the strict aliasing rule.
Fixed by making the intermediary variables volatile (
to not re-introduce the excess precision bug) and using
the intermediary value instead of the char * buffer.
Note that there can be loss of precision for both signed
and unsigned 64 bit integers converted to double and back,
so the check must stay there (even for compatibility 
reasons).
Based on the excellent analysis in bug 28400.

ALTER VIEW is currently not supported as a prepared statement
and should be disabled as such as they otherwise could cause server crashes.

ALTER VIEW is currently not supported when called from stored
procedures or functions for related reasons and should also be disabled.

This patch disables these DDL statements and adjusts the appropriate test
cases accordingly.

Additional tests has been added to reflect on the fact that we do support
CREATE/ALTER/DROP TABLE for Prepared Statements (PS), Stored Procedures (SP)
and PS within SP.


mysql-test/r/ps_1general.result:
  - Updated test to reflect on the new policy to disallow ALTER VIEW within SP.
mysql-test/r/sp-dynamic.result:
  - Added PS ALTER TABLE test from within SP-context to demonstrate that CREATE/ALTER/DROP
  TABLE statements is working.
  - Added PS CREATE/ALTER/DROP VIEW tests from within SP-context to show that
  ALTER VIEW is not supported, CREATE VIEW/DROP VIEW are supported.
mysql-test/r/sp-error.result:
  - Updated test to reflect on the new policy to disallow VIEW DDL within SP.
mysql-test/t/ps_1general.test:
  - Updated test to reflect on the new policy to disallow VIEW DDL within SP.
mysql-test/t/sp-dynamic.test:
  - Add PS ALTER TABLE test from within SP to demonstrate that CREATE/ALTER/DROP
  TABLE statements are supported.
mysql-test/t/sp-error.test:
  - Updated test to reflect on the new policy to disallow ALTER VIEW
  within SP-context.
  - Changed error code 1314 to the more abstract ER_SP_BADSTATEMENT.
sql/sql_class.h:
  - Added comment for clarity
sql/sql_parse.cc:
  - Added comment for clarity
sql/sql_prepare.cc:
  - Disallow ALTER VIEW as prepared statements until they are
    properly supported. Note that SQLCOM_CREATE_VIEW also handles ALTER VIEW
    statements.
sql/sql_view.cc:
  - converted to doxygen comments
  - Added comment for clarity
sql/sql_yacc.yy:
  - Disallow ALTER VIEW statements within a SP.
  If the parser is operating within the SP context, this is shown
  on the sp->sphead pointer. If this flag is set for view DDL operations
  we stop parsing with the error 'ER_SP_BAD_STATEMENT'.

  inconsistent column results hidden

The reason the "reap;" succeeds unexpectedly is because the query was completing(almost always) and the network buffer was big enough to store the query result (sometimes) on Windows, meaning the response was completely sent before the server thread could be killed.

Therefore we use a much longer running query that doesn't have a chance to fully complete before the reap happens, testing the kill properly.


mysql-test/r/kill.result:
  We use a much longer running query that doesn't have a chance to fully complete before the reap happens.

- When creating an index for the sort, the number of rows plus 1 is used 
to allocate a buffer.  In this test case, the number of rows 4294967295 
is the max value of an unsigned integer, so when 1 was added to it, a 
buffer of size 0 was allocated causing the crash.
- Create new test suite for this bug's test suite as per QA.

long shared-memory-base-names could overflow a static internal buffer
and thus crash mysqld and various clients.  change both to dynamic
buffers, show everything but overflowing those buffers still works.

The test case for this would pretty much amount to
mysqld --shared-memory-base-name=HeyMrBaseNameXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX --shared-memory=1 &
mysqladmin --no-defaults --shared-memory-base-name=HeyMrBaseNameXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX shutdown

Unfortunately, we can't just use an .opt file for the
server. The .opt file is used at start-up, before any
include in the actual test can tell mysqltest to skip
this one on non-Windows. As a result, such a test would
break on unices.

Fixing mysql-test-run.pl to export full path for master
and slave would enable us to start a server from within
the test which is ugly and, what's more, doesn't work as
the server blocks (mysqltest offers no fire-and-forget
fork-and-exec), and mysqladmin never gets run.

Making the test rpl_windows_shm or some such so we can
is beyond ugly. As is introducing another file-name based
special case (run "win*.test" only when on Windows). As is
(yuck) coding half the test into mtr (as in, having it
hand out a customized environment conductive to the shm-
thing on Win only).

Situation is exacerbated by the fact that .sh is not
necessary run as expected on Win.

In short, it's just not worth it. No test-case until we
have a new-and-improved test framework.
