12000-11-27 Michael Widenius <monty@mysql.com> 2 3* Changed mi_create.c to use less stack. 4 52000-08-23 Michael Widenius <monty@mysql.com> 6 7* Fixed bug when comparing DECIMAL/NUMERIC key parts. 8 92000-08-17 Michael Widenius <monty@mysql.com> 10 11* Add a new flag in share.staus so that we can quickly check if a table 12 is analyzed or not! 13 142000-07-02 Michael Widenius <monty@mysql.com> 15 16* Added safety margin to guard against full index file. 17 182000-05-22 Michael Widenius <monty@mysql.com> 19 20* Fixed that --join works with myisampack. 21 222000-05-14 Michael Widenius <monty@mysql.com> 23 24* Don't lock datafile during myisamchk (only indexfile is locked; This is good 25 enough for all MyISAM functions); This made it possible to close datafile 26 in rep_by_sort(). 27 282000-05-04 Michael Widenius <monty@mysql.com> 29 30* Fixed bug in code that scanned after rows in a crashed table. 31 This could cause an infinite loop when repairing tables. 32 332000-04-26 Michael Widenius <monty@mysql.com> 34 35* Fixed bug when doing read_next after a delete/insert which balanced key 36 pages (In this case one internal buffer was wrongly reused) 37 382000-04-21 Michael Widenius <monty@tik.pp.sci.fi> 39 40* Changed mi_find_halfpos() to return key, key_length and pos after key. 41* Don't join or split key buffers in the middle when inserting a key 42 that is bigger than all other keys; This will improve inserts when 43 doing these in sorted order. 44 452000-04-04 Michael Widenius <monty@mysql.com> 46 47* Added support for different languages on key part level. 48 492000-02-23 Michael Widenius <monty@monty.pp.sci.fi> 50 51* Fixed that myisamchk works properly with RAID. 52 532000-02-07 Michael Widenius <monty@tik.pp.sci.fi> 54 55* Added delete and rename of tables (works with RAID tables) 56 572000-01-29 Michael Widenius <monty@monty.pp.sci.fi> 58 59* Fixed the sorting of index works with prefix-packed keys. 60 611999-11-24 Michael Widenius <monty@monty.pp.sci.fi> 62 63* Fixed that DECIMAL() keys are sorted correct for negative numbers. 64 651999-11-22 Michael Widenius <monty@monty.pp.sci.fi> 66 67* removed 'NO_LOCKING' macros. 68* Added function mi_rnext_same 69* Added support for concurrent reads. 70 711999-11-05 Michael Widenius <monty@tik.pp.sci.fi> 72 73* Added function mi_scan(). 74* Changed all functions to return error number in case of errors. 75 761999-08-17 Michael Widenius <monty@tik.pp.sci.fi> 77 78* Added option DELAY_KEY_WRITE to tables and mi_open() 79 801999-08-10 Michael Widenius <monty@tik.pp.sci.fi> 81 82* Added support of HA_READ_PREFIX_LAST to mi_rkey(). This finds the last 83 row with the given prefix. 84 85Mon Aug 2 13:54:35 1999 Michael Widenius <monty@bitch.pp.sci.fi> 86 87* Added data- and key-file-length to myisamchk. 88* Fixed some problems with null and space packed keys. 89 901999-07-15 Michael Widenius <monty@tik.pp.sci.fi> 91 92* The following options are for COUNT(DISTINCT ..) 93* Added option HA_EXTRA_NO_ROWS; In this case only the index tree is updated 94* Added mi_delete_all_rows() 95 961999-07-13 Michael Widenius <monty@tik.pp.sci.fi> 97 98* Added special handling of tempoary tables 99 1001999-06-12 Michael Widenius <monty@monty.pp.sci.fi> 101 102* Added optional checksum for file and for each dynamic-length row 103* Added unique constraint checking 104 1051999-05-06 Michael Widenius <monty@tik.pp.sci.fi> 106 107* All index blocks of the same size now share the same key block delete link 108 1091999-03-17 Michael Widenius <monty@monty.pp.sci.fi> 110 111* Different key packing code depending on if the first key part 112 is a variable length column (space packed, BLOB or VARCHAR) 113* The create interface allows one to specify a key segment to start and 114 end one a specific bit. (The bit handling isn't yet implemented) 115* Added more tests to 'test1' 116 1171999-03-16 Michael Widenius <monty@monty.pp.sci.fi> 118 119* Added option -m to myisamchk as an alternative to -e (-m is faster but 120 not as quite as safe as -e). 121* Added option --fast to not check not changed tables. 122* The first update will set a bit that the table has been changed. 123* The first update to a table increments a 'open_count' field. This will 124 be reset on close. This will allow myisamchk to find tables that hasn't 125 been properly closed! 126* Support for true VARCHAR columns 127 1281999-03-01 Michael Widenius <monty@monty.pp.sci.fi> 129 130* Dynamic length blocks are double linked to allow easy reallocation 131 of block lengths. This will help that the dynamic length data will not be 132 as fragmented as with ISAM. 133* Extended mypack_isam to compress BLOB/TEXT columns. 134* Allow keys on BLOB. 135 1361999-02-06 Michael Widenius <monty@monty.pp.sci.fi> 137 138* Keys, key pointers and all varibles in the index file are stored in 139 high-endian-order to get better compression. 140* Allow NULL on keys 141 1421998-10-29 Michael Widenius <monty@monty.pp.sci.fi> 143 144* All data is stored in low-endian order 145 (This means that the files will be architecture and OS independent) 146* All record numbers are now of type 'ha_rows' and file pointer are now of type 147 my_off_t. One can use files with 32-64 bit pointers with a 32bit or 64bit 148 record handling. 149 Currently the code is limited to 5 bytes pointers, but this is real easy 150 to change. 151
