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.
