(The bit handling isn't yet implemented) +* Added more tests to 'test1' + +1999-03-16 Michael Widenius <monty@monty.pp.sci.fi> + +* Added option -m to myisamchk as an alternative to -e (-m is faster but + not as quite as safe as -e). +* Added option --fast to not check not changed tables. +* The first update will set a bit that the table has been changed. +* The first update to a table increments a 'open_count' field. This will + be reset on close. This will allow myisamchk to find tables that hasn't + been properly closed! +* Support for true VARCHAR columns + +1999-03-01 Michael Widenius <monty@monty.pp.sci.fi> + +* Dynamic length blocks are double linked to allow easy reallocation + of block lengths. This will help that the dynamic length data will not be + as fragmented as with ISAM. +* Extended mypack_isam to compress BLOB/TEXT columns. +* Allow keys on BLOB. + +1999-02-06 Michael Widenius <monty@monty.pp.sci.fi> + +* Keys, key pointers and all varibles in the index file are stored in + high-endian-order to get better compression. +* Allow NULL on keys + +1998-10-29 Michael Widenius <monty@monty.pp.sci.fi> + +* All data is stored in low-endian order + (This means that the files will be architecture and OS independent) +* All record numbers are now of type 'ha_rows' and file pointer are now of type + my_off_t. One can use files with 32-64 bit pointers with a 32bit or 64bit + record handling. + Currently the code is limited to 5 bytes pointers, but this is real easy + to change. |
