on duplicate key".

INSERT ... SELECT ... ON DUPLICATE KEY UPDATE which was used in
stored routine or as prepared statement and which in its ON DUPLICATE
KEY clause erroneously tried to assign value to a column mentioned only
in its SELECT part was properly emitting error on the first execution
but succeeded on the second and following executions.

Code which is responsible for name resolution of fields mentioned in
UPDATE clause (e.g. see select_insert::prepare()) modifies table list
and Name_resolution_context used in this process. It uses
Name_resolution_context_state::save_state/restore_state() to revert
these modifications. Unfortunately those two methods failed to revert
properly modifications to TABLE_LIST::next_name_resolution_table
and this broke name resolution process for successive executions.

This patch fixes Name_resolution_context_state::save_state/restore_state()
in such way that it properly handles TABLE_LIST::next_name_resolution_table.

tables' lock."

Execution of ALTER TABLE ... ENABLE KEYS on a table (which can take rather
long time) prevented concurrent execution of all statements using tables.

The problem was caused by the fact that we were holding LOCK_open mutex
during whole duration of this statement and particularly during call
to handler::enable_indexes(). This behavior was introduced as part of the
fix for bug 14262 "SP: DROP PROCEDURE|VIEW (maybe more) write to binlog
too late (race cond)"

The patch simply restores old behavior. Note that we can safely do this as
this operation takes exclusive lock (similar to name-lock) which blocks both
DML and DDL on the table being altered.

It also introduces mysql-test/include/wait_show_pattern.inc helper script
which is used to make test-case for this bug robust enough.

The problem was that the events_bugs test could randomly fail due to
races in the test case.

The solution is to replace fixed sleeps with reliable polling of a
certain state to settle.  For that, a new auxiliary script
include/wait_condition.inc is used, that allows waiting for a given
query to return true.

WL#3681 (ALTER TABLE ORDER BY)

Before this fix, the ALTER TABLE statement implemented an ORDER BY option
with the following characteristics :

1) The order by clause accepts a list of criteria, with optional ASC or
DESC keywords

2) Each criteria can be a general expression, involving operators,
native functions, stored functions, user defined functions, subselects ...

With this fix :

1) has been left unchanged, since it's a de-facto existing feature,
that was already present in the code base and partially covered in the test
suite. Code coverage for ASC and DESC was missing and has been improved.

2) has been changed to limit the kind of criteria that are permissible:
now only a column name is valid.

The problem was that if a prepared statement accessed a view, the
access to the tables listed in the query after that view was done in
the security context of the view.

The bug was in the assigning of the security context to the tables
belonging to a view: we traversed the list of all query tables
instead.  It didn't show up in the normal (non-prepared) statements
because of the different order of the steps of checking privileges
and descending into a view for normal and prepared statements.

The solution is to traverse the list and stop once the last table
belonging to the view was processed.
