if cached query uses many tables
The problem was that query cache would not properly cache
queries which used 256 or more tables but yet would leave
behind query cache blocks pointing to freed (destroyed)
data. Later when invalidating (due to a truncate) query cache
would attempt to grab a lock which resided in the freed data,
leading to hangs or undefined behavior.
This was happening due to a improper return value from the
function responsible for registering the tables used in the
query (so the cache can be invalidated later if one of the
tables is modified). The function expected a return value of
type boolean (char, 8 bits) indicating success (1) or failure
(0) but the number of tables registered (unsigned int, 32 bits)
was being returned instead. This caused the function to return
failure for cases where it had actually succeed because when
a type (unsigned int) is converted to a narrower type (char),
the excess bits on the left are discarded. Thus if the 8
rightmost bits are zero, the return value will be 0 (failure).
The solution is to simply return true (1) only if the number of
registered table is greater than zero and false (0) otherwise.

Problem was an unclear error message since it could suggest that
MyISAM did not support INSERT DELAYED.
Changed the error message to say that DELAYED is not supported by the
table, instead of the table's storage engine.
The confusion is that a partitioned table is in somewhat sense using
the partitioning storage engine, which in turn uses the ordinary
storage engine. By saying that the table does not support DELAYED we
do not give any extra informantion about the storage engine or if it
is partitioned.

Fix for this bug and additional improvements/fixes
In detail:
- Remove unicode attribute from several columns
(unicode properties were nowhere needed/tested)
of the table tb3
-> The runnability of these tests depends no more on
the availibility of some optional collations.
- Use a table tb3 with the same layout for all
engines to be tested and unify the engine name
within the protocols.
-> <engine>_trig_<abc>.result have the same content
- Do not load data into tb3 if these rows have no
impact on result sets
- Add tests for NDB (they exist already in 5.1)
- "--replace_result" at various places because
NDB variants of tests failed with "random" row
order in results
This fixes a till now unknown weakness within the
funcs_1 NDB tests existing in 5.1 and 6.0
- Fix the expected result of ndb_trig_1011ext
which suffered from Bug 32656
+ disable this test
- funcs_1 could be executed with the mysql-test-run.pl
option "--reorder", which saves some runtime by
optimizing server restarts.
Runtimes on tmpfs (one attempt only):
with reorder 132 seconds
without reorder 183 seconds
- Adjust two "check" statements within func_misc.test
which were incorrect (We had one run with result set
difference though the server worked good.)
- minor fixes in comments
Upmerge of fix for this bug and a second similar problem
found during experimenting.
This replaces the first fix (already pushed to 5.1
and merged to 6.0) which
- failed in runs with the embedded server
- cannot be ported back to 5.0

first row or fails with an error:
ERROR 1022 (23000): Can't write; duplicate key in table ''
The server uses intermediate temporary table to store updated
row data. The first column of this table contains rowid.
Current server implementation doesn't reset NULL flag of that
column even if the server fills a column with rowid.
To keep each rowid unique, there is an unique index.
An insertion into an unique index takes into account NULL
flag of key value and ignores real data if NULL flag is set.
So, insertion of actually different rowids may lead to two
kind of problems. Visible effect of each of these problems
depends on an initial engine type of temporary table:
1. If multiupdate initially creates temporary table as
a MyISAM table (a table contains blob columns, and the
create_tmp_table function assumes, that this table is
large), it inserts only one single row and updates
only rows with one corresponding rowid. Other rows are
silently ignored.
2. If multiupdate initially creates MEMORY temporary
table, fills it with data and reaches size limit for
MEMORY tables (max_heap_table_size), multiupdate
converts MEMORY table into MyISAM table and fails
with an error:
ERROR 1022 (23000): Can't write; duplicate key in table ''
Multiupdate has been fixed to update the NULL flag of
temporary table rowid columns.

slave
The stored-routine code took the contents of the (lowest) parser
and copied it directly to the binlog, which causes problems if there
is a special case of interpretation at the parser level -- which
there is, in the "/*!VER */" comments. The trailing "*/" caused
errors on the slave, naturally.
Now, since by that point we have /properly/ created parse-tree (as
the rest of the server should do!) for the stored-routine CREATE, we
can construct a perfect statement from that information, instead of
writing uncertain information from an unknown parser state.
Fortunately, there's already a function nearby that does exactly
that.

In create_string, we may not have a sp_name parameter yet, so
instead pass the char* and length of the only member we'd get out

CREATE (FUNC|TRIG|PROC) statement to the binlog as we always used
to display the statement to the user.

sql/item_strfunc.cc:
Fixed bug #36488.
The Item_func_concat::val_str method is optimized to
use first non-empty argument of the CONCAT function for in-place
result accumulation. This optimization is acceptable if that
first argument is not a constant.
However, current implementation checks this condition only for
the first actual argument of the CONCAT function.
So, the Item_func_concat::val_str method can corrupt values
of, for example, literal strings by appending random data.
The Item_func_concat::val_str method has been modified to take
into account the ability to be modified in-place for the first
non-empty argument.
subselects into account
It is forbidden to use the SELECT INTO construction inside UNION statements
unless on the last SELECT of the union. The parser records whether it
has seen INTO or not when parsing a UNION statement. But if the INTO was
legally used in an outer query, an error is thrown if UNION is seen in a
subquery. Fixed in 5.0 by remembering the nesting level of INTO tokens and
mitigate the error unless it collides with the UNION.
