A prerequisite for several fulltext and XML bugs.
MY_CHARSET_HANDLER now has a new function "ctype"
to detect a type of the next character in a string
(i.e. digit, letter, space, punctuation, control, etc),
which now works correctly for both 8bit and multibyte charsets.
Previously only 8bit charsets worked correctly,
while any multibyte character was considered as letter
in multibyte charsets.
Many files:
Adding new function
Makefile.am:
Adding build rules for uctypedump,
a dump tool to create my_uctype.h
using Unicode Character Database file.
m_ctype.h:
Adding declaration of my_uni_ctype,
ctype data for Unicode.
Adding new member into MY_CHARSET_HANDLER
Makefile.am:
Adding my_uctype.h into noinst_HEADERS
my_uctype.h, uctypedump.c:
new files:
ctype data for unicode,
and the tool to generate it from
a Unicode Character Database file.
When InnoDB compares varchar field in ucs2 with given key using bin collation,
it calls my_strnncollsp_ucs2_bin() to perform comparison.
Because field length was lesser than length of key field should be padded
with trailing spaces in order to get correct result.
Because my_strnncollsp_ucs2_bin() was calling my_strnncollp_ucs2_bin(), which
doesn't pads field, wrong comparison result was returned. This results in
wrong result set.
my_strnncollsp_ucs2_bin() now compares fields like my_strnncollsp_ucs2 do,
but using binary collation.
into parts when converting to Unicode.
m_ctype.h:
Reorganizing mb_wc return codes to be able
to return "an unassigned N-byte-long character".
sql_string.cc:
Adding code to detect and properly handle
unassigned characters (i.e. the those character
which are correctly formed according to the
character specifications, but don't have Unicode
mapping).
Many files:
Fixing conversion function to return new codes.
ctype_ujis.test, ctype_gbk.test, ctype_big5.test:
Adding a test case.
ctype_ujis.result, ctype_gbk.result, ctype_big5.result:
Fixing results accordingly.
new file
mysql_fix_privilege_tables.sql, mysql_create_system_tables.sh:
Adding true BINARY/VARBINARY: fixing "password" type, not to be 0x00-padding.
Many files:
Adding true BINARY/VARBINARY: fixing tests not to output 0x00 bytes.
Adding true BINARY/VARBINARY: new pad_char structure member.
ctype-bin.c:
Adding true BINARY/VARBINARY: new pad_char structure member.
New strnxfrm, with two trailing length bytes.
field.cc:
Adding true BINARY/VARBINARY.
index doesn't return correct result
item_cmpfunc.cc:
Use charset of LIKE to decide whether
to use 8bit or Unicode "escape" value.
But use charset of "escape" to scan escape character.
strings/ctype-xxx.c:
We cannot reduce "end" pointer using charpos(),
because of possible escape characters in the string.
Limit the loop using count of written characters instead.
ctype_like_escape.inc:
new file
mysql-test/t/ctype_xxx:
mysql-test/r/ctype_xxx:
Adding test case.
In cp932, '\' character can be the second byte in a
multi-byte character stream. This makes it difficult to use
mysql_escape_string. Added flag to indicate which languages allow
'\' as second byte of multibyte sequence so that when putting a prepared
statement into the binlog we can decide at runtime whether hex encoding
is really needed.
ctype-cp932.c:
ctype-gbk.c:
ctype-mb.c:
ctype-simple.c:
ctype-sjis.c:
ctype-ucs2.c:
ctype-ujis.c:
ctype-utf8.c:
Adding explicit cast to return type
in pointer substructions to avoid
warnings from some compilers.
Fixing tests accordingly.
ctype-ucs2.c:
The same fix for UCS2.
ctype-utf8.c:
Bug #9557
MyISAM utf8 table crash
The problem was that my_strnncollsp_xxx could
return big value in the range 0..0xffff.
for some constant pairs it could return 32738,
which is defined as MI_FOUND_WRONG_KEY in
myisamdef.h. As a result, table considered to
be crashed.
Fix to return -1,0 or 1.
UPPER/LOWER now can return a string with different length.
mi_test1.c:
Adding new arguments.
Many files:
Changeing caseup/casedn to return a result with different
length than argument.
sql_string.h:
Removing unused method,
mysql_priv.h:
Removing unused method
Gluh's SESSION/GLOBAL for @variables fix in sql_yacc.yy and
Bar's well_formed_len() changes in ndb code
did not make it and should be re-applied manually
Windows to call CreateFileMapping() with correct arguments, and
propogating the introduction of query_id_t to everywhere query ids are
passed around. (Bug #8826)
Change string->float conversion to delay division as long as possible.
This gives us more exact integer->float conversion for numbers of type '123.45E+02' (Bug #7740)
Renamed HA_VAR_LENGTH to HA_VAR_LENGTH_PART
Renamed in all files FIELD_TYPE_STRING and FIELD_TYPE_VAR_STRING to MYSQL_TYPE_STRING and MYSQL_TYPE_VAR_STRING to make it easy to catch all possible errors
Added support for VARCHAR KEYS to heap
Removed support for ISAM
Now only long VARCHAR columns are changed to TEXT on demand (not CHAR)
Internal temporary files can now use fixed length tables if the used VARCHAR columns are short
Bug#5523 Test failure: 'ctype_uca'
Type cast should have been applied to shift and bit-and operation results, not to min_sort_char/max_sort_char before the operation.
