- * Changed mi_create.c to use less stack.
- 2000-08-23 Michael Widenius <monty@mysql.com>
- * Fixed bug when comparing DECIMAL/NUMERIC key parts.
- 2000-08-17 Michael Widenius <monty@mysql.com>
- * Add a new flag in share.staus so that we can quickly check if a table
- is analyzed or not!
- 2000-07-02 Michael Widenius <monty@mysql.com>
- * Added safety margin to guard against full index file.
- 2000-05-22 Michael Widenius <monty@mysql.com>
- * Fixed that --join works with myisampack.
- 2000-05-14 Michael Widenius <monty@mysql.com>
- * Don't lock datafile during myisamchk (only indexfile is locked; This is good
- enough for all MyISAM functions); This made it possible to close datafile
- in rep_by_sort().
- 2000-05-04 Michael Widenius <monty@mysql.com>
- * Fixed bug in code that scanned after rows in a crashed table.
- This could cause an infinite loop when repairing tables.
- 2000-04-26 Michael Widenius <monty@mysql.com>
- * Fixed bug when doing read_next after a delete/insert which balanced key
- pages (In this case one internal buffer was wrongly reused)
- 2000-04-21 Michael Widenius <monty@tik.pp.sci.fi>
- * Changed mi_find_halfpos() to return key, key_length and pos after key.
- * Don't join or split key buffers in the middle when inserting a key
- that is bigger than all other keys; This will improve inserts when
- doing these in sorted order.
- 2000-04-04 Michael Widenius <monty@mysql.com>
- * Added support for different languages on key part level.
- 2000-02-23 Michael Widenius <monty@monty.pp.sci.fi>
- * Fixed that myisamchk works properly with RAID.
- 2000-02-07 Michael Widenius <monty@tik.pp.sci.fi>
- * Added delete and rename of tables (works with RAID tables)
- 2000-01-29 Michael Widenius <monty@monty.pp.sci.fi>
- * Fixed the sorting of index works with prefix-packed keys.
- 1999-11-24 Michael Widenius <monty@monty.pp.sci.fi>
- * Fixed that DECIMAL() keys are sorted correct for negative numbers.
- 1999-11-22 Michael Widenius <monty@monty.pp.sci.fi>
- * removed 'NO_LOCKING' macros.
- * Added function mi_rnext_same
- * Added support for concurrent reads.
- 1999-11-05 Michael Widenius <monty@tik.pp.sci.fi>
- * Added function mi_scan().
- * Changed all functions to return error number in case of errors.
- 1999-08-17 Michael Widenius <monty@tik.pp.sci.fi>
- * Added option DELAY_KEY_WRITE to tables and mi_open()
- 1999-08-10 Michael Widenius <monty@tik.pp.sci.fi>
- * Added support of HA_READ_PREFIX_LAST to mi_rkey(). This finds the last
- row with the given prefix.
- Mon Aug 2 13:54:35 1999 Michael Widenius <monty@bitch.pp.sci.fi>
- * Added data- and key-file-length to myisamchk.
- * Fixed some problems with null and space packed keys.
- 1999-07-15 Michael Widenius <monty@tik.pp.sci.fi>
- * The following options are for COUNT(DISTINCT ..)
- * Added option HA_EXTRA_NO_ROWS; In this case only the index tree is updated
- * Added mi_delete_all_rows()
- 1999-07-13 Michael Widenius <monty@tik.pp.sci.fi>
- * Added special handling of tempoary tables
- 1999-06-12 Michael Widenius <monty@monty.pp.sci.fi>
- * Added optional checksum for file and for each dynamic-length row
- * Added unique constraint checking
- 1999-05-06 Michael Widenius <monty@tik.pp.sci.fi>
- * All index blocks of the same size now share the same key block delete link
- 1999-03-17 Michael Widenius <monty@monty.pp.sci.fi>
- * Different key packing code depending on if the first key part
- is a variable length column (space packed, BLOB or VARCHAR)
- * The create interface allows one to specify a key segment to start and
- end one a specific bit. (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.
