Magne Mahre	bd97e771a1	Bug #14637 : trim trailing spaces processes data only byte wise (From: gkodinov) Use and int * where possible to scan for trailing space in a string instead of always iterating char-by-char. Using the attached benchmark file on a 32 bit Intel Core 2 Duo CPU I've got 43485 ms run with the fix compared to 44373 without it. Backported to 5.6.0 (next-mr-runtime) 6.0-codebase revid: 2476.1362.1	16 years ago
V Narayanan	3b02f76aaf	Bug#46448 trailing spaces are not ignored when user collation maps space != 0x20 In MySQL when the mapping for space is changed to something other than 0x20 by defining a different collation, then space is not ignored when comparing two strings. This was happening because the function that performs the comparison of two strings while ignoring ending spaces, was comparing the collation value of a space with the ascii value of the ' ' character. This should be changed to do comparison between the collated values.	16 years ago

knielsen@loke.(none)	5dc5fc8292	BUG#31799: Scrambled number output due to integer overflow An integer overflow in number->string conversion caused completely wrong output of the number LONGLONG_MIN with gcc 4.2.1.

kaa@polly.(none)	e0691da0c1	Fix for bug #30453 : String not cast to int correctly. Problem: my_strntoull10rnd_8bit() handled incorrectly cases when the input string contains a decimal point and is long enough to overrun the 'unsigned long long' type. The position of the decimal point was not taken into account which resulted in miscalculated numbers and truncation to appropriate SQL data type limits. Solution: Fix my_strntoull10rnd_8bit() to take the position of a decimal point into account in such cases.	18 years ago

evgen@moonbone.local	ff3fd46c32	Bug#29461: Sort order of the collation wasn't used when comparing characters with the space character. When the my_strnncollsp_simple function compares two strings and one is a prefix of another then this function compares characters in the rest of longer key with the space character to find whether the longer key is greater or less. But the sort order of the collation isn't used in this comparison. This may lead to a wrong comparison result, wrongly created index or wrong order of the result set of a query with the ORDER BY clause. Now the my_strnncollsp_simple function uses collation sort order to compare the characters in the rest of longer key with the space character.	19 years ago

monty@mysql.com/narttu.mysql.fi	088e2395f1	WL#3817: Simplify string / memory area types and make things more consistent (first part) The following type conversions was done: - Changed byte to uchar - Changed gptr to uchar* - Change my_string to char * - Change my_size_t to size_t - Change size_s to size_t Removed declaration of byte, gptr, my_string, my_size_t and size_s. Following function parameter changes was done: - All string functions in mysys/strings was changed to use size_t instead of uint for string lengths. - All read()/write() functions changed to use size_t (including vio). - All protocoll functions changed to use size_t instead of uint - Functions that used a pointer to a string length was changed to use size_t* - Changed malloc(), free() and related functions from using gptr to use void * as this requires fewer casts in the code and is more in line with how the standard functions work. - Added extra length argument to dirname_part() to return the length of the created string. - Changed (at least) following functions to take uchar* as argument: - db_dump() - my_net_write() - net_write_command() - net_store_data() - DBUG_DUMP() - decimal2bin() & bin2decimal() - Changed my_compress() and my_uncompress() to use size_t. Changed one argument to my_uncompress() from a pointer to a value as we only return one value (makes function easier to use). - Changed type of 'pack_data' argument to packfrm() to avoid casts. - Changed in readfrm() and writefrom(), ha_discover and handler::discover() the type for argument 'frmdata' to uchar** to avoid casts. - Changed most Field functions to use uchar* instead of char* (reduced a lot of casts). - Changed field->val_xxx(xxx, new_ptr) to take const pointers. Other changes: - Removed a lot of not needed casts - Added a few new cast required by other changes - Added some cast to my_multi_malloc() arguments for safety (as string lengths needs to be uint, not size_t). - Fixed all calls to hash-get-key functions to use size_t. (Needed to be done explicitely as this conflict was often hided by casting the function to hash_get_key). - Changed some buffers to memory regions to uchar to avoid casts. - Changed some string lengths from uint to size_t. - Changed field->ptr to be uchar* instead of char*. This allowed us to get rid of a lot of casts. - Some changes from true -> TRUE, false -> FALSE, unsigned char -> uchar - Include zlib.h in some files as we needed declaration of crc32() - Changed MY_FILE_ERROR to be (size_t) -1. - Changed many variables to hold the result of my_read() / my_write() to be size_t. This was needed to properly detect errors (which are returned as (size_t) -1). - Removed some very old VMS code - Changed packfrm()/unpackfrm() to not be depending on uint size (portability fix) - Removed windows specific code to restore cursor position as this causes slowdown on windows and we should not mix read() and pread() calls anyway as this is not thread safe. Updated function comment to reflect this. Changed function that depended on original behavior of my_pwrite() to itself restore the cursor position (one such case). - Added some missing checking of return value of malloc(). - Changed definition of MOD_PAD_CHAR_TO_FULL_LENGTH to avoid 'long' overflow. - Changed type of table_def::m_size from my_size_t to ulong to reflect that m_size is the number of elements in the array, not a string/memory length. - Moved THD::max_row_length() to table.cc (as it's not depending on THD). Inlined max_row_length_blob() into this function. - More function comments - Fixed some compiler warnings when compiled without partitions. - Removed setting of LEX_STRING() arguments in declaration (portability fix). - Some trivial indentation/variable name changes. - Some trivial code simplifications: - Replaced some calls to alloc_root + memcpy to use strmake_root()/strdup_root(). - Changed some calls from memdup() to strmake() (Safety fix) - Simpler loops in client-simple.c	19 years ago

bar@mysql.com/bar.intranet.mysql.r18.ru	d18fcb3a0f	Bug#20404: SHOW CREATE TABLE fails with Turkish I Problem: SHOW CREATE TABLE printed garbage in table name for tables having TURKISH I (i.e. LATIN CAPITABLE LETTER I WITH DOT ABOVE) when lower-case-table-name=1. Reason: In some cases during lower/upper conversion in utf8, the result string can be shorter the original string (including the above letter). Old implementation of caseup_str() and casedn_str() didn't handle the result length properly, assuming that length cannot change. This fix changes the result type of cs->cset->casedn_str() and cs->cset->caseup_str() from VOID to UINT, to return the result length, as well as put '\0' terminator on a proper place. Also, my_caseup_str_utf8() and my_casedn_str_utf8() were rewritten not to use strlen() for performance purposes. It was done with help of adding of new functions - my_utf8_uni_no_range() and my_uni_utf8_no_range() - for null terminated strings.	19 years ago
bar@mysql.com/bar.intranet.mysql.r18.ru	29bc5cc179	Bug#6147: Traditional: Assigning a string to a numeric column has unexpected results The problem was that when converting a string to an exact number, rounding didn't work, because conversion didn't understand approximate numbers notation. Fix: a new function for string-to-number conversion was implemented, which is aware of approxinate number notation (with decimal point and exponent, e.g. -19.55e-1)	20 years ago
bar@mysql.com	df2d425afd	Bug#16233: XML: ExtractValue() fails with special characters ExtractValue didn't understand tag and attribute names consisting of "tricky" national letters (e.g. latin accenter letters).

bar@mysql.com	d7c773834b	WL#1386 - CTYPE table for unicode character sets 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.
