Problem: SOUNDEX returned an invalid string for international
characters in multi-byte character sets.
For example: for a Chinese/Japanese 3-byte long character
_utf8 0xE99885 it took only the very first byte 0xE9,
put it into the outout string and then appended with three
DIGIT ZERO characters, so the result was 0xE9303030 - which
is an invalide utf8 string.
Fix: make SOUNDEX() multi-byte aware and - put only complete
characters into result, thus return only valid strings.
This patch also makes SOUNDEX() compatible with UCS2.

what it actually means (Monty approved the renaming)
- correcting description of transaction_alloc command-line options
(our manual is correct)
- fix for a failure of rpl_trigger.
mysql-test/t/rpl_misc_functions.test:
test was cleaning up only on slave, but it's also needed on master,
otherwise it influences rpl_trigger.test
sql/lock.cc:
clearer name
sql/mysqld.cc:
I checked the code that those two variables are not about binlogging
but about the size of the transaction's memroot which is used
to create savepoint structures and to store list of tables to be invalidated
(for NDB). The manual has a correct description, no need to fix it.
sql/sql_base.cc:
clearer name
sql/sql_derived.cc:
clearer name
sql/sql_select.cc:
clearer name
sql/table.h:
clearer name: TMP_TABLE is used for non-transactional tables.

When rand() is called multiple times inside a stored procedure, the server does
not binlog the correct random seed values.
This patch corrects the problem by resetting rand_used= 0 in
THD::cleanup_after_query() allowing the system to save the random seeds if needed
for each command in a stored procedure body.
However, rand_used is not reset if executing in a stored function or trigger
because these operations are binlogged by call and thus only the calling statement
need detect the call to rand() made by its substatements. These substatements must
not set rand_used to 0 because it would remove the detection of rand() by the
calling statement.
mysql-test/r/rpl_misc_functions.result:
Bug #25543 Replication of wrong values if using rand() in stored procedure
The result file was modified to include the correct processing of the new
additions to the test. The results from execution are written to files on
both the master and the slave. The files are compared to ensure the values
from rand() generated on the master are correctly generated on the slave.
mysql-test/t/rpl_misc_functions.test:
Bug #25543 Replication of wrong values if using rand() in stored procedure
The test was modified to include a test of a stored procedure that calls

slave. The files are compared to ensure the values from rand() generated
on the master are correctly generated on the slave.
sql/sql_class.cc:
Bug #25543 Replication of wrong values if using rand() in stored procedure
The code was modified to reset rand_used so that detection of calls to rand()
will save random seeds if needed by the slave.

causes incorrect duplicate entries
Keys for BTREE indexes on ENUM and SET columns of MEMORY tables
with character set UTF8 were computed incorrectly. Many
different column values got the same key value.
Apart of possible performance problems, it made unique indexes
of this type unusable because it rejected many different
values as duplicates.
The problem was that multibyte character detection was tried
on the internal numeric column value. Many values were not
identified as characters. Their key value became blank filled.
Thanks to Alexander Barkov and Ramil Kalimullin for the patch,
which sets the character set of ENUM and SET key segments to
the pseudo binary character set.

my_seek: Assertion `fd != -1' failed"
In difficult optimize/repair situations the server could crash.
Under some circumstances the server retries an optimize/repair
with more elaborate options. But it did not check if the first
attempt failed so badly that a second one must not be tried.
This could happen when a new data file has been created
but it was not possible to open it. In this case the
repair leaves behind a table with closed data file.
This must not be used for another repair attempt.
We do now detect the closed data file and do not try
another repair attempt in this situation.
No test case. The required table corruption can not be
repeated easily. There is a test program attached to
bug 25433.
sql/ha_myisam.cc:
Bug#25289 - repair table causes "my_seek.c:56:
my_seek: Assertion `fd != -1' failed"
Added code to detect a closed data file. It could be closed
by a preceeding repair attempt. We must not try another
repair then.

When the DEFINER clause isn't specified in the ALTER statement then it's loaded
from the view definition. If the definer differs from the current user then
the error is thrown because only a super-user can set other users as a definers.
Now if the DEFINER clause is omitted in the ALTER VIEW statement then the
definer from the original view is used without check.

suppressing warnings. And if the context
happens to enable warnings (e.g. INSERT ..

the data the key is compared to are
reported to the client.
Fixed by suppressing warnings when converting
the data to the same type as the key parts.

The problem in this bug is when we create temporary tables. When
temporary tables are created for unions, there is some
inferrence being carried out regarding the type of the column.
Whenever this column type is inferred to be REAL (i.e. FLOAT or
DOUBLE), MySQL will always try to maintain exact precision, and
if that is not possible (there are hardware limits, since FLOAT
and DOUBLE are stored as approximate values) will switch to
using approximate values. The problem here is that at this point
the information about number of significant digits is not
available. Furthermore, the number of significant digits should
be increased for the AVG function, however, this was not properly
handled. There are 4 parts to the problem:
#1: DOUBLE and FLOAT fields don't display their proper display
lengths in max_display_length(). This is hard-coded as 53 for
DOUBLE and 24 for FLOAT. Now changed to instead return the
field_length.
#2: Type holders for temporary tables do not preserve the
max_length of the Item's from which they are created, and is
instead reverted to the 53 and 24 from above. This causes
*all* fields to get non-fixed significant digits.
#3: AVG function does not update max_length (display length)
when updating number of decimals.
#4: The function that switches to non-fixed number of
significant digits should use DBL_DIG + 2 or FLT_DIG + 2 as
cut-off values (Since fixed precision does not use the 'e'
notation)
Of these points, #1 is the controversial one, but this
change is preferred and has been cleared with Monty. The
function causes quite a few unit tests to blow up and they had
to b changed, but each one is annotated and motivated. We
frequently see the magical 53 and 24 give way to more relevant
numbers.

delta 1: field was originally declared as DOUBLE with no display
length, so the hardware maximum is chosen rather than 53.
delta 2: fields exceed the maximum precision and thus switch to
non-fixed significant digits
delta 3: Same as above, number of decmals and significant digits
was not specified when t3 was created.

Test case
sql/field.h:
bug#24791
The method max_display_length is reimplemented as
uint32 max_display_length() { return field_length; }
in Field_double and Field_float. Since all subclasses of
Field_real now have the same implementation of this method, the
implementation has been moved up the hierarchy to Field_real.
sql/item.cc:
bug#24791
We switch to a non-fixed number of significant digits
(by setting decimals=NOT_FIXED_DECIMAL) if the calculated
display length is greater than the display length of a value
with the maximum precision. These values differ for double and
float, obviously.
sql/item_sum.cc:
bug#24791
We must increase the display length accordinly whenever we
change number of decimal places.

fix for cast( AS DATETIME)+0 in 5.0 and above versions.
val_real now works using val_decimal for DATETIME Items
Superfluous val_real() methods deleted
sql/item_timefunc.h:
val_real() for datetime functions implemented
as { return val_real_from_decimal(); }
It's not a fastest possible way, but code is simple and less
error-prone, what i belive is more important here as this part
works unfrequently.

the decimal expression had been evaluated to NULL.

aggregated in outer context returned wrong results.
This happened only if the subquery did not contain any references
to outer fields.
As there were no references to outer fields the subquery erroneously
was taken for non-correlated one.
Now any set function aggregated in outer context makes the subquery
correlated.

To correctly decide which predicates can be evaluated with a given table
the optimizer must know the exact set of tables that a predicate depends
on. If that mask is too wide (refer to non-existing tables) the optimizer
can erroneously skip a predicate.
One such case of wrong table usage mask were the aggregate functions.
The have a all-1 mask (meaning depend on all tables, including non-existent
ones).
Fixed by making a real used_tables mask for the aggregates. The mask is
constructed in the following way :
1. OR the table dependency masks of all the arguments of the aggregate.
2. If all the arguments of the function are from the local name resolution
context and it is evaluated in the same name resolution
context where it is referenced all the tables from that name resolution
context are OR-ed to the dependency mask. This is to denote that an
aggregate function depends on the number of rows it processes.
3. Handle correctly the case of an aggregate function optimization (such that
the aggregate function can be pre-calculated and made a constant).
Made sure that an aggregate function is never a constant (unless subject of a
specific optimization and pre-calculation).
One other flaw was revealed and fixed in the process : references were
not calling the recalculation method for used_tables of their targets.
