Bug#18396916 MAIN.OUTFILE_LOADDATA TEST FAILS ON ARM, AARCH64, PPC/PPC64
The recorded results for the failing tests were wrong.
They were introduced by the patch for
Bug#30946 mysqldump silently ignores --default-character-set when used with --tab
Correct results were returned for platforms where 'char' is implemented as unsigned.
This was reported as
Bug#46895 Test "outfile_loaddata" fails (reproducible)
Bug#11755168 46895: TEST "OUTFILE_LOADDATA" FAILS (REPRODUCIBLE)
The patch for that bug fixed only parts of the problem,
leaving the incorrect results in the .result file.
Solution: use 'uchar' for field_terminator and line_terminator on all platforms.
Also: remove some un-necessary casts, leaving the ones we actually need.

truncates text/blob to 766 chars
mysqldump and SELECT ... INTO OUTFILE truncated long BLOB/TEXT
values to size of 766 bytes (MAX_FIELD_WIDTH or 255 * 3 + 1).
The select_export::send_data method has been modified to
reallocate a conversion buffer for long field data.

Bug #53088: mysqldump with -T & --default-character-set set
truncates text/blob to 766 chars
The select_export::send_data method has been modified to
reallocate a conversion buffer for long field data.

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:
Added test case for bug #30946.
mysql-test/r/outfile_loaddata.result:
Added test case for bug #30946.
mysql-test/t/mysqldump.test:
Added test case for bug #30946.
mysql-test/t/outfile_loaddata.test:
Added test case for bug #30946.
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.

8bit escape characters, termination and enclosed characters
were silently ignored by SELECT INTO query, but LOAD DATA INFILE
algorithm is 8bit-clean, so data was corrupted during
encoding.
sql/sql_class.cc:
Fixed bug #32533.
SELECT INTO OUTFILE encoding was not 8bit clear, it
has been fixed for a symmetry with the LOAD DATA INFILE
decoding algorithm.
mysql-test/t/outfile_loaddata.test:
Added test case for bug #32533.
mysql-test/r/outfile_loaddata.result:
Added test case for bug #32533.

in the SELECT INTO OUTFILE clause starts with a special
character (one of n, t, r, b, 0, Z or N) and ENCLOSED BY
is empty, every occurrence of this character within a
field value is duplicated.
Duplication has been avoided.
New warning message has been added: "First character of
the FIELDS TERMINATED string is ambiguous; please use
non-optional and non-empty FIELDS ENCLOSED BY".
mysql-test/r/outfile_loaddata.result:
BitKeeper file /home/uchum/work/bk/5.0-opt-31663/mysql-test/r/outfile_loaddata.result
Added test case for bug #31663.
mysql-test/t/outfile_loaddata.test:
BitKeeper file /home/uchum/work/bk/5.0-opt-31663/mysql-test/t/outfile_loaddata.test
Added test case for bug #31663.
sql/sql_class.h:
Fixed bug #31663.
The select_export::is_ambiguous_field_term field has been added.
This field is true if select_export::field_sep_char contains
the first char of the FIELDS TERMINATED BY (ENCLOSED BY is empty),
and items can contain this character.
The select_export::field_term_char field has been added (first
char of the FIELDS TERMINATED BY string or INT_MAX).
sql/sql_class.cc:
Fixed bug #31663.
The select_export::prepare method has been modified to calculate
a value of the select_export::is_ambiguous_field_term field and
to warn if this value is true.
The select_export::send_data method has been modified to
avoid escaping or duplication of the field_set_char if
is_ambiguous_field_term is true.
sql/share/errmsg.txt:
Fixed bug #31663.
The ER_AMBIGUOUS_FIELD_TERM warning has been added.
