Bug #48370 Absolutely wrong calculations with GROUP BY and
decimal fields when using IF
Added the test cases in the above two bugs for regression
testing.
Added additional tests that demonstrate a incomplete fix.
Added a new factory method for Field_new_decimal to
create a field from an (decimal returning) Item.
In the new method made sure that all the precision and
length variables are capped in a proper way.
This is required because Item's can have larger precision
than the decimal fields and thus need to be capped when
creating a field based on an Item type.
Fixed the wrong typecast to Item_decimal.

Bug#32082 : definition of VOID in my_global.h conflicts with Windows
SDK headers
VOID macro is now removed. Its usage is replaced with void cast.
In some cases, where cast does not make much sense (pthread_*, printf,
hash_delete, my_seek), cast is ommited.

We set up DATE and TIMESTAMP differently in field-creation than we
did in field-MD creation (for CREATE). Admirably, ALTER TABLE
detected this and didn't damage any data, but it did initiate a
full copy/conversion, which we don't really need to do.
Now we describe Field and Create_field the same for those types.
As a result, ALTER TABLE that only changes meta-data (like a
field's name) no longer forces a data-copy when there needn't
be one.
mysql-test/r/alter_table.result:
0 rows should be affected when a meta-data change is enough ALTER TABLE.
mysql-test/t/alter_table.test:
add test-case: show that we don't do a full data-copy on ALTER TABLE
when we don't need to.
sql/field.cc:
Remove Field_str::compare_str_field_flags() (now in Field/Create_field as
field_flags_are_binary().
Correct some field-lengths!
sql/field.h:
Clean-up: use defined constants rather than numeric literals for certain
field-lengths.
Add enquiry-functions binaryp() to classes Field and Create_field.
This replaces field.cc's Field_str::compare_str_field_flags().

Altering a table to update a column with types DATE or TIMESTAMP
would incorrectly be seen as a significant change that necessitates
a slow copy+rename operation instead of a fast update.
There were two problems:
The character set is magically set for TIMESTAMP to be "binary",
but that was done too deep in field use code for ALTER TABLE to
know of it. Now, put that in the constructor for Field_timestamp.
Also, when we set the character set for the new replacement/
comparison field, also raise the "binary" field flag that tells us
we should compare it exactly. That is necessary to match the old
stored definition.
Next is the problem that the default length for TIMESTAMP and DATE
fields is different than the length read from the .frm . The
compressed size is written to the file, but the human-readable,
part-delimited length is used as default length. IIRC, for
timestamp it was 19!=14, and for date it was 8!=10. Length
mismatch causes a table copy.
Also, clean up a place where a comparison function alters one of its
parameters and replace it with an assertion of the condition it
mutates.

The problem was that appending values to the end of an existing
ENUM or SET column was being treated as table data modification,
preventing a immediately (fast) table alteration that occurs when
only table metadata is being modified.
The cause was twofold: adding a enumeration or set members to the
end of the list of valid member values was not being considered
a "compatible" table alteration, and for SET columns, the check
was being done upon the max display length and not the underlying
(pack) length of the field.
The solution is to augment the function that checks wether two ENUM
or SET fields are compatible -- by comparing the pack lengths and
performing a limited comparison of the member values.
mysql-test/r/alter_table.result:
Add test case result for Bug#45567
mysql-test/t/alter_table.test:
Add test case for Bug#45567
sql/field.cc:
Check whether two fields can be considered 'equal' for table
alteration purposes. Fields are equal if they retain the same
pack length and if new members are added to the end of the list.
sql/field.h:
Add comment and remove method.

To-number conversion warnings work differenly with CHAR
and VARCHAR sp variables.
The original revision-IDs are:
staale.smedseng@sun.com-20081124095339-2qdvzkp0rn1ljs30
staale.smedseng@sun.com-20081125104611-rtxic5d12e83ag2o
The patch provides ER_TRUNCATED_WRONG_VALUE warning messages
for conversion of VARCHAR to numberic values, in line with
messages provided for CHAR conversions. Conversions are
checked for success, and the message is emitted in case
failure.
The tests are amended to accept the added warning messages,
and explicit conversion of ON/OFF values is added for
statements checking system variables. In test
rpl.rpl_switch_stm_row_mixed checking for warnings is
temporarily disabled for one statement, as this generates
warning messages for strings that vary between executions.
sql/field.cc:
The pushing of the truncation warning is now done in a
separate static function, and used in various places.

with gcc 4.3.2
This patch fixes a number of GCC warnings about variables used
before initialized. A new macro UNINIT_VAR() is introduced for
use in the variable declaration, and LINT_INIT() usage will be
gradually deprecated. (A workaround is used for g++, pending a
patch for a g++ bug.)
GCC warnings for unused results (attribute warn_unused_result)
for a number of system calls (present at least in later
Ubuntus, where the usual void cast trick doesn't work) are
also fixed.
client/mysqlmanager-pwgen.c:
A fix for warn_unused_result, adding fallback to use of
srand()/rand() if /dev/random cannot be used. Also actually
adds calls to rand() in the second branch so that it actually
creates a random password.

The problem was that creating a DECIMAL column from a decimal
value could lead to a failed assertion as decimal values can
have a higher precision than those attached to a table. The
assert could be triggered by creating a table from a decimal
with a large (> 30) scale. Also, there was a problem in
calculating the number of digits in the integral and fractional
parts if both exceeded the maximum number of digits permitted
by the new decimal type.
The solution is to ensure that truncation procedure is executed
when deducing a DECIMAL column from a decimal value of higher
precision. If the integer part is equal to or bigger than the
maximum precision for the DECIMAL type (65), the integer part
is truncated to fit and the fractional becomes zero. Otherwise,
the fractional part is truncated to fit into the space left
after the integer part is copied.
This patch borrows code and ideas from Martin Hansson's patch.
mysql-test/r/type_newdecimal.result:
Add test case result for Bug#45261. Also, update test case to
reflect that an additive operation increases the precision of
the resulting type by 1.
mysql-test/t/type_newdecimal.test:
Add test case for Bug#45261
sql/field.cc:
Added DBUG_ASSERT to ensure object's invariant is maintained.
Implement method to create a field to hold a decimal value
from an item.
sql/field.h:
Explain member variable. Add method to create a new decimal field.
sql/item.cc:
The precision should only be capped when storing the value
on a table. Also, this makes it impossible to calculate the
integer part if Item::decimals (the scale) is larger than the
precision.
sql/item.h:
Simplify calculation of integer part.
sql/item_cmpfunc.cc:
Do not limit the precision. It will be capped later.
sql/item_func.cc:
Use new method for allocating a new decimal field.
Add a specialized method for retrieving the precision
of a user variable item.
sql/item_func.h:
Add method to return the precision of a user variable.
sql/item_sum.cc:
Use new method for allocating a new decimal field.
sql/my_decimal.h:
The integer part could be improperly calculated for a decimal
with 31 digits in the fractional part.
sql/sql_select.cc:
Use new method which truncates the integer or decimal parts
as needed.

column on partitioned table
An assertion 'ASSERT_COULUMN_MARKED_FOR_READ' is failed if the query
is executed with index containing double column on partitioned table.
The problem is that assertion expects all the fields which are read,
to be in the read_set.
In this query only the field 'a' is in the readset as the tables in
the query are joined by the field 'a' and so the assertion fails
expecting other field 'b'.
Since the function cmp() is just comparison of two parameters passed,
the assertion is not required.
Fixed by removing the assertion in the double fields comparision
function and also fixed the index initialization to do ordered
index scan with RW LOCK which ensures all the fields from a key are in
the read_set.
Note: this bug is not reproducible with other datatypes because the
assertion doesn't exist in comparision function for other
datatypes.
mysql-test/r/partition.result:
Testcase for BUG#45816
mysql-test/t/partition.test:
Testcase for BUG#45816
sql/field.cc:
Removed the assertion ASSERT_COLUMN_MARED_FOR_READ in Field_double::cmp()
function
sql/ha_partition.cc:
Fixed index_int() method to make it initialize the read_set properly if
ordered index scan with RW lock is requested.

when used with --tab
1) New syntax: added CHARACTER SET clause to the
SELECT ... INTO OUTFILE (to complement the same clause in
LOAD DATA INFILE).
mysqldump is updated to use this in --tab mode.
2) ESCAPED BY/ENCLOSED BY field parameters are documented as
accepting CHAR argument, however SELECT .. INTO OUTFILE
silently ignored rests of multisymbol arguments.
For the symmetrical behavior with LOAD DATA INFILE the
server has been modified to fail with the same error:
ERROR 42000: Field separator argument is not what is
expected; check the manual
3) Current LOAD DATA INFILE recognizes field/line separators
"as is" without converting from client charset to data
file charset. So, it is supposed, that input file of
LOAD DATA INFILE consists of data in one charset and
separators in other charset. For the compatibility with
that [buggy] behaviour SELECT INTO OUTFILE implementation
has been saved "as is" too, but the new warning message
has been added:
Non-ASCII separator arguments are not fully supported
This message warns on field/line separators that contain
non-ASCII symbols.
client/mysqldump.c:
mysqldump has been updated to call SELECT ... INTO OUTFILE
statement with a charset from the --default-charset command
line parameter.
mysql-test/r/mysqldump.result:

sql/field.cc:
String conversion code has been moved from check_string_copy_error()
to convert_to_printable() for reuse.
sql/share/errmsg.txt:
New WARN_NON_ASCII_SEPARATOR_NOT_IMPLEMENTED message has been added.
sql/sql_class.cc:
The select_export::prepare() method has been modified to:
1) raise the ER_WRONG_FIELD_TERMINATORS error on multisymbol
ENCLOSED BY/ESCAPED BY field arguments like LOAD DATA INFILE;
2) warn with a new WARN_NON_ASCII_SEPARATOR_NOT_IMPLEMENTED
message on non-ASCII field or line separators.
The select_export::send_data() merhod has been modified to
convert item data to output charset (see new SELECT INTO OUTFILE
syntax). By default the BINARY charset is used for backward
compatibility.
sql/sql_class.h:
The select_export::write_cs field added to keep output
charset.
sql/sql_load.cc:
mysql_load has been modified to warn on non-ASCII field or
line separators with a new WARN_NON_ASCII_SEPARATOR_NOT_IMPLEMENTED
message.
sql/sql_string.cc:
New global function has been added: convert_to_printable()
(common code has been moved from check_string_copy_error()).
sql/sql_string.h:
New String::is_ascii() method and new global convert_to_printable()
function have been added.
sql/sql_yacc.yy:
New syntax: added CHARACTER SET clause to the
SELECT ... INTO OUTFILE (to complement the same clause in
LOAD DATA INFILE). By default the BINARY charset is used for
backward compatibility.

Compiling MySQL with gcc 4.3.2 and later produces a number of
warnings, many of which are new with the recent compiler
versions.
This bug will be resolved in more than one patch to limit the
size of changesets. This is the first patch, fixing a number
of the warnings, predominantly "suggest using parentheses
around && in ||", and empty for and while bodies.

Field_time::get_time() did not initialize some members of
MYSQL_TIME which led to valgrind warnings when those members
were accessed in Protocol_simple::store_time().
It is unlikely that this bug could result in wrong data
being returned, since Field_time::get_time() initializes the
'day' member of MYSQL_TIME to 0, so the value of 'day'
in Protocol_simple::store_time() would be 0 regardless
of the values for 'year' and 'month'.

UNION could convert fixed-point FLOAT(M,D)/DOUBLE(M,D) columns
to FLOAT/DOUBLE when aggregating data types from the SELECT
substatements. While there is nothing particularly wrong with
this behavior, especially when M is greater than the hardware
precision limits, it could be confusing in cases when all
SELECT statements in a union have the same
FLOAT(M,D)/DOUBLE(M,D) columns with equal precision
specifications listed in the same position.
Since the manual is quite vague on what data type should be
returned in such cases, the bug was fixed by implementing the
most 'expected' behavior: do not convert FLOAT(M,D)/DOUBLE(M,D)
to anything else if all SELECT statements in a UNION have the
same precision for that column.

procedure, uservar
A stored procedure involving substrings could crash the server on certain
platforms because of invalid memory reads.
During storing the new blob-field value, the cached value's address range
overlapped that of the new field value. This caused problems when the
cached value storage was reallocated to provide access for a new
characater set representation. The patch checks the address ranges, and if
they overlap, the new field value is copied to a new storage before it is
converted to the new character set.
mysql-test/r/sp.result:
Added result set
mysql-test/t/sp.test:

sql/field.cc:
The source and destination address ranges of a character conversion must not overlap or the 'from' address will be invalidated as the temporary value-
