push_warning(MYSQL_ERROR::WARN_LEVEL_ERROR)).
The Signal/Resignal patch changes the push_warning() API: now
it silently downgrades WARN_LEVEL_ERROR to WARN_LEVEL_WARN.
This patch should be rolled back when Bug#47233 is fixed.
During insert, we are not reading the rows in a referring table but
instead using the last read row that happens to be in table->record[0].
Now INSERT into such view is denied.

BUG#38049 "incorrect rows estimations with references from preceding table"
(from revid:sergefp@mysql.com-20090126194259-ue20il3qro529l4d).
Compared to 6.0 where EXPLAIN indicates "Using index condition", here in join_optimizer.result
we see "Using where"; it's normal; 6.0 shows the same if disabling Index Condition Pushdown.
The flag EXTRA_ACL is used in conjugation with our access checks, yet it is
not clear what impact this flag has.
This is a code clean up which replaces use of EXTRA_ACL with an explicit
function parameter.
The patch also fixes privilege checks for:
- SHOW CREATE TABLE: The new privilege requirement is any privilege on
the table-level.
- CHECKSUM TABLE: Requires SELECT on the table level.
- SHOW CREATE VIEW: Requires SHOW_VIEW and SELECT on the table level
(just as the manual claims)
- SHOW INDEX: Requires any privilege on any column combination.

EXPLAIN EXTENDED warning.
Query optimizer searches for the constant tables and optimizes them away. This
means that fields of such tables are substituted for their values and on later
phases they are treated as constants. After this constant tables are removed
from the query execution plan. Nevertheless constant tables were shown in
the EXPLAIN EXTENDED warning thus producing query that might be not an
equivalent of the original query.
Now the print_join function skips all tables that were optimized away from
printing to the EXPLAIN EXTENDED warning. If all tables were optimized away it
produces the 'FROM dual' clause.

Bug#30302: Tables that were optimized away are printed in the
EXPLAIN EXTENDED warning.
Now the print_join function skips all tables that were optimized away from
printing to the EXPLAIN EXTENDED warning. If all tables were optimized away it
produces the 'FROM dual' clause.
sql/table.h:
Adjusted test case result after fix for the bug#30302.
The optimized_away flag is added to the TABLE_LIST struct.
rpl_semi_sync_master_wait_sessions was reset by FLUSH STATUS,
which could cause the master fail to wake up waiting sessions and
result in master timeout waiting for slave reply.
rpl_semi_sync_master_wait_session should not be reset, this
problem is fixed by this patch.
plugin/semisync/semisync_master_plugin.cc:
Change wait_sessions from SHOW_LONG back to SHOW_FUNC so that it will not be reset by FLUSH STATUS.

Fix for Bug#38992: Server crashes sporadically with
'waiting for initial ...' msg on windows.
The problem is that connection timeout is too small
for busy windows box.
The fix is to
- add support for connect_timeout command line argument
to mysqltest;
- set default value of the connect_timeout option to
120 seconds.

message:
WL#3288, step 1: ensure that the SQL layer always closes an open
cursor (rnd or index read) before closing a handler.
sql/handler.h:
Assert that the read is closed in handler destructor.
sql/sql_select.cc:
Remove JOIN::table which was a piece of redundancy. The problem was
that JOIN::cleanup() works only if JOIN::table is not null,
but JOIN::cleanup also assigns JOIN::table to NULL. This assignment
is apparently there for safety, from the times when we had no support for correlated
subqueries. Indeed, in case of a evaluation of a correlated subquery more than once it led
to JOIN::cleanup doing nothing, and leaving the rnd or index read open.
In do_select(), make sure we call JOIN::join_free() even in case of an
error.
sql/sql_select.h:
Remove JOIN::table, JOIN::all_tables has the same functionality.
