--local-infile=0 checks can be bypassed by sending a FETCH LOCAL FILE response
  
Add a check for CLIENT_LOCAL_FILES before sending a local file.
Beware, that all binary distributions enable sending of local files and it's up
to the programs which use libmysql to disable it, if they don't use this functionality.
Otherwise they are not safe.


client/mysqltest.c:
  Enable LOAD DATA LOCAL INFILE for the test suite, like some rpl and ndb test.
sql-common/client.c:
  Check if the client has LOAD DATA LOCAL INFILE disabled and
  don't serve such requests from the server. This is not 100% proof,
  as if the client has this enabled, in all binary builds for BC,
  the check won't work and the client can be tricked into sending a
  local file.
tests/mysql_client_test.c:
  Switch on LOCAL INFILE in client test. If one day there
  is a test which uses it, then it will work out of the box.

Disabled events weren't removed from the memory queue after the scheduler has been
re-enabled. After recalculation of next execution time of an event, it might get disabled.


sql/event_queue.cc:
  Sort the event queue in a way that the disabled events will always be
  at the end. We will use this for cleaning it, starting from the end.
  
  After recalculating times in the queue, after the scheduler has been enabled
  after disabled state, the queue should be cleaned from DISABLED events.
  The queue is sorted in a way such that the disabled events are at the end.
  Thus, we can start from the end of the queue and remove all DISABLED till we
  find the first with different state.

between 5.0 and 5.1.
  
The problem was that in the patch for Bug#11986 it was decided
to store original query in UTF8 encoding for the INFORMATION_SCHEMA.
This approach however turned out to be quite difficult to implement
properly. The main problem is to preserve the same IS-output after
dump/restore.
  
So, the fix is to rollback to the previous functionality, but also
to fix it to support multi-character-set-queries properly. The idea
is to generate INFORMATION_SCHEMA-query from the item-tree after
parsing view declaration. The IS-query should:
  - be completely in UTF8;
  - not contain character set introducers.
  
For more information, see WL4052.

The problem is that CREATE VIEW statements inside prepared statements
weren't being expanded during the prepare phase, which leads to objects
not being allocated in the appropriate memory arenas.

The solution is to perform the validation of CREATE VIEW statements
during the prepare phase of a prepared statement. The validation
during the prepare phase assures that transformations of the parsed
tree will use the permanent arena of the prepared statement.

sending SIGHUP.

There were two problems:
  - after some recent fix, the server started to crash after
    receiving SIGHUP. That happened because LEX of new THD-object
    was not properly initialized.
  - user-specified log options were ignored when logs were reopened.

The fix is to 1) initialize LEX and 2) take user-specified options
into account.

There is no test case in this CS, because our test suite does not
support sending SIGHUP to the server.


sql/mysqld.cc:
  Use proper logging after SIGHUP.
sql/sql_parse.cc:

The problem is that when a stored procedure is being parsed for
the first execution, the body is copied to a temporary buffer
which is disregarded sometime after the statement is parsed.
And during this parsing phase, the rule for CREATE VIEW was
holding a reference to the string being parsed for use during
the execution of the CREATE VIEW statement, leading to invalid
memory access later.

The solution is to allocate and copy the SELECT of a CREATE
VIEW statement using the thread memory root, which is set to
the permanent arena of the stored procedure.

sql/sql_view.cc:

sql/sql_yacc.yy:
  Allocate the SELECT of a CREATE VIEW using the current thread
  memory root and remove any leading and trailing whitespace.

Executing a prepared statement associated with a materialized
cursor yields to the client a metadata packet with wrong table
and database names. The problem was occurring because the server
was sending the the name of the temporary table used by the cursor
instead of the table name of the original table. The same problem
occurs when selecting from views, in which case the table name was
being sent and not the name of the view.
  
The solution is to fill the list item from the temporary table but
preserving the table and database names of the original fields. This
is achieved by tweaking the Select_materialize to accept a pointer to
the Materialized_cursor class which contains the item list to be filled.

  Fill the item list in the send_fields method and preserve
  the table and database name of the fields.

The idea of the fix is to ensure that we always commit the current
statement at the end of dispatch_command(). In order to not issue
redundant disc syncs, an optimization of the two-phase commit

the transaction is read-only.
