2000-11-27  Michael Widenius  <monty@mysql.com>

* 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.
