* Changed locking code to get better handling of locks of different types.
1998-08-09 Michael Widenius <monty@monty.pp.sci.fi>
* mysqld will now ignore trailing ';' characters in queries. This is to
make it easier to emigrate from some other SQL servers that require the
end ';'

a given number of rows.
* Fix for corrupted output of fixed format and SELECT INTO OUTFILE:
select * from test into outfile "/tmp/test.txt" fields terminated by '' enclosed by ''

* Add support for INSERT INTO table ... VALUES(...),(...),(...)
1998-08-03 Michael Widenius <monty@monty.pp.sci.fi>
* Added Oracle GREATEST() and LEAST() functions. One must now use
these instead if the MAX() and MIN() functions to get the biggest/smallest

string values.
* The following query now uses indexing instead of sorting the table:
SELECT ... FROM table ORDER BY key_part1 desc,key_part2 desc,...
* Added check that the error message file has enough error messages.
* DAYOFWEEK() had offset 0 for Sunday. Changed the offset to 1.

* new option to mysql: '--vertical' to print results in vertical mode.
* All count structures in the client (affected_rows, insert_id...) are now of
type BIGINT to allow one to use 64 bit values.
This required a minor change in the MySQL protocol which may affect
old clients when using tables with auto_increment values > 24M.
* The return type of mysql_fetch_lengths() has changed from uint *
to ulong *. This may give a warning for old clients but should work
on most machines.
Thu Jul 30 15:29:05 1998 Michael Widenius <monty@tik>
* COUNT(), STD() and AVG() are extended to handle more than 4G rows.
Wed Jul 29 10:36:05 1998 Michael Widenius <monty@tik>

(instead of uname()).
Sun Jul 12 12:38:45 1998 Michael Widenius <monty@tik>
* Index only optimization; Some queries are now resolved using
only indexes. Until MySQL 4.0 this works only for number columns.
SELECT key_part1,key_part2 FROM table WHERE key_part1=#
SELECT COUNT(*) FROM table WHERE key_part1=# and key_part2=#
SELECT key_part2 FROM table GROUP BY key_part1;
SELECT * FROM table ORDER BY key_part2;

* MySQL now automaticly changes a query from an ODBC client:
SELECT ... from table WHERE auto_increment_column IS NULL
to
SELECT ... from table WHERE auto_increment_column == LAST_INSERT_ID().
This allows some ODBC programs (Delphi, Access) to retrieve the newly
inserted row to fetch the auto_increment id.
* Drop table now waits for all users to free a table before deleting it
1998-07-02 Michael Widenius <monty@monty.pp.sci.fi>

WHERE/ON expression with uniquely identifies one record.
1998-06-07 Michael Widenius <monty@monty.pp.sci.fi>

Tue May 5 14:41:47 1998 Michael Widenius <monty@bitch.pp.sci.fi>
* String functions now return VARCHAR() instead of CHAR() and
the column type is now VARCHAR() for fields saved as VARCHAR().
This should make the MyODBC driver better, but may break some old
MySQL clients that doesn't handle FIELD_TYPE_VARCHAR identical as
FIELD_TYPE_CHAR.
Mon May 4 00:33:27 1998 Michael Widenius <monty@bitch.pp.sci.fi>

for crackers to kill mysqld trough telnet + TCP/IP.
1998-03-24 Michael Widenius <monty@monty.pp.sci.fi>
* new mysqld option --big-selects:
Allow big result sets by saving all temporary sets on file.
(Solves most 'table full' errors)
1998-03-21 Michael Widenius <monty@monty.pp.sci.fi>
* WHERE with string-column-key = constant-string didn't always find all rows
if the column had many values differing only with characters of the same sort
value (like e and <20>).
* Added opened_tables to 'show status'.
* Strings keys looked up with 'ref' was not compared case sensitively.

* Changed protocol (downward compatible) to mark if a column
is auto_increment or a timestamp. This is needed for the
new java driver.

characters over 127.
Thu Dec 18 00:33:25 1997 <monty@monty.pp.sci.fi>
* Fixed core dump in first() when chaning some very specific AND and OR
key columns.
* Fixed lock problem: When freeing a read lock on a table with multiple
read locks, a thread waiting for write lock would have given the lock.
This shouldn't affect data integrity, but could possible make mysqld
to restart if one thread was reading data that another thread modified.
* LIMIT offset,count didn't work in INSERT ... SELECT.
Wed Dec 17 12:35:11 1997 <monty@monty.pp.sci.fi>
* optimized key block caching. This will be quicker than the old one when
using bigger key caches.
Tue Dec 16 23:33:24 1997 <monty@monty.pp.sci.fi>
* Changed bool to my_bool in some item structures to use less memory.

(One couldn't insert more than 1 record in such a table).
Fri Dec 12 18:31:32 1997 <monty@monty.pp.sci.fi>
* Added ODBC and ANSI SQL style LEFT OUTER JOIN.
The following are new reserved words: LEFT, NATURAL, USING
* Changed use of table bits and key bits to use typedefs to make it easy
to extend join tables and keys to 64.
* The client library is now using the environment variable MYSQL_HOST as
the default host if it's defined.
Wed Dec 10 01:29:11 1997 <monty@monty.pp.sci.fi>
* Release of 3.21.16a

ROUND(2 arg) and TRUNCATE().
* Added optional (ignored) argument to CURRENT_TIME() and CURRENT_TIMESTAMP().
* LOCATE() parameters where swapped according to ODBC standard. Fixed.
* Added detection of all ODBC 3.0 functions to crash-me
* In some cases default values was not used for NOT NULL fields.
* Timestamp wasn't updated in UPDATE SET... if the timestamp was used as
a value or in the WHERE clause.
Sun Nov 30 04:06:31 1997 <monty@monty.pp.sci.fi>
* Renamed version.h to mysql_version.h
Sat Nov 29 10:50:28 1997 <monty@monty.pp.sci.fi>

* Allow DATE '1997-01-01', TIME '12:10:10' and TIMESTAMP '1997-01-01 12:10:10'
formats required by ANSI SQL.
This has the unfortunate side-effect that one can't have columns named
DATE, TIME or TIMESTAMP anymore :(
* Changed net_write() to my_net_write() because of name conflict with sybase.
* Added --no-auto-rehash option to mysql.
* Added VARBINARY as synonym for VARCHAR BINARY

(patch by Zeev Suraski)
* Recoded all delete item to avoid use of stack space for deletes.
(For crash-me)
* Added command: SET SQL_LOG_OFF=1 to not log commands to standard log.
This will only affect users with process list privileges.
Sat Nov 22 13:08:55 1997 <monty@monty.pp.sci.fi>
* Added stack checking for crash-me :)
The following failed before: select 1+1+1+1+1+.... (687 times)
Fri Nov 21 01:50:34 1997 <monty@monty.pp.sci.fi>
* Added new patch for Chinese Big5 code.

to the client as field_length.
Thu Nov 20 15:37:05 1997 <monty@monty.pp.sci.fi>
* fixed bug in range-optimizer that crashed mysql on some queries.
* table and column name completion for mysql by
Zeev Suraski and Andi Gutmans
* Fixed problem with queries that didn't find any records: This happens only
when using multiple part keys where the first part is a number and some
other part is a char or varchar.
* Removed some wrong warning messages from range optimizer
Wed Nov 19 16:41:14 1997 <monty@monty.pp.sci.fi>

Sun Nov 16 21:41:32 1997 <monty@monty.pp.sci.fi>
* The thread stack was overwritten if one tried to create a table with too many
fields (more than 1000).

Thu Nov 13 03:12:54 1997 <monty@monty.pp.sci.fi>
* ALTER TABLE forgot BINARY attribute for strings and BLOBS
* Change comparision of strings to integer to compare as floats instead
of as integers.

This isn't compleat yet.
Wed Nov 12 00:28:58 1997 <monty@monty.pp.sci.fi>
* Added automatic removal of 'ODBC function conversions': {fn now() }
* Added new function DATE_FORMAT(date_expr,format). The format string is the
same one that was previously integrated with from_unix_timestamp().
* Changed from_unix_timestamp() to call function DATE_FORMAT() with format
element.
Mon Nov 10 18:17:39 1997 <monty@monty.pp.sci.fi>
* Added flag for stupid ODBC applications (like access) that wants found_rows
instead of affected_rows.
* Added basic functions for handling av ANSI INTERVAL.
Sat Nov 8 01:20:03 1997 <monty@monty.pp.sci.fi>
* compare with DATE and TIME with NULL didn't work. (IS NULL worked)

Wed Nov 5 13:10:10 1997 Michael Widenius <monty@analytik>
* SORTING on calculated DOUBLE values sorted on integer results instead.
* SELECT ... WHERE KEY=constant ORDER BY ... didn't use key to retrieve
records. This was slow because everything was sorted..
* CHECK isn't a reserved word anymore.
Mon Nov 3 07:55:47 1997 Michael Widenius <monty@monty.pp.sci.fi>
* Allow start of mysqld.cc without a current database.
* Changed server version to include -debug and -log if compiled with debugging
and to show that one has a logging enabled.
Sat Nov 1 13:08:00 1997 <monty@monty.pp.sci.fi>
* Added missing expression 'NOT IN'
* Changed the place where HAVING should be. According to ANSI it should be
after GROUP BY but before ORDER BY. MySQL 3.20 had it wrongly last.
* Added Sybase command: USE DATABASE to start using another database.
* Fixed core dump when one had a wrong password in the password column.
* Added automatic adjusting of number of connections and table cache size
if the maximum number of files that can be opened are less than needed.
This should fix that mysqld doesn't crash even if one hasn't done a
ulimit -n 256 before starting mysqld.
* Added limit checks for create table.
* Added more checks of different errors from net_read for SCO port.
Tue Oct 28 14:30:31 1997 <monty@monty.pp.sci.fi>

open 256 files.
Mon Oct 27 10:02:19 1997 <monty@monty.pp.sci.fi>
* Added options LINE STARTING WITH to LOAD DATA INFILE and
SELECT ... into outfile. Now one can do:
LOAD DATA INFILE '/tmp/syslog.sql' INTO TABLE uptime
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED by "'"
LINES STARTING WITH 'VALUES (' LINES TERMINATED by ');\n' ignore 100 lines
and
SELECT * from uptime into outfile '/tmp/syslog2.sql'
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED by "'"
LINES STARTING WITH 'INSERT INTO uptime VALUES (' LINES TERMINATED by ');\n'
* Added IGNORE # LINES to LOAD DATA INFILE.
* Allow \N as a shorthand of NULL in SQL statements.
Sun Oct 26 11:34:38 1997 <monty@monty.pp.sci.fi>
* More memory checking.
* Fixed grouping of functions with many from tables.
Sat Oct 25 01:46:27 1997 <monty@monty.pp.sci.fi>
* New error message so one can check if the connection was lost while
the command was running or if the connection was down from the start.
* The mysql command tool now does a automatic reconnect if the connection
was lost when it does a query.
* new command: 'mysqladmin debug'. This forces the server to dump out some
useful information to stdout. Currently it prints all lock information.
* Rewrite lexer to be faster and more easy to extend.
Fri Oct 24 13:57:06 1997 <monty@monty.pp.sci.fi>
* Fixed bug when like on number key.

grouped.
* Now SQL_BIG_TABLES + DISTINCT is also optimized.
* Changed the syntax of ALTER TABLE ... ALTER COLUMN ident SET DEFAULT ...
(The DEFAULT keyword wasn't allowed or required before).
* Added russian error messages.
Mon Oct 20 04:10:53 1997 <monty@monty.pp.sci.fi>
* LIKE with '_' as last character didn't work. Fixed
* Added many error checks for 'end of memory'

New reserved words: MATCH, FULL, PARTIAL
Sun Oct 19 23:13:50 1997 <monty@monty.pp.sci.fi>
* Force .log to logfile-name if one uses hostname as logfile.
* mysqld now allows ip and hostname to the --bind-address option.
Sat Oct 18 22:02:36 1997 <monty@monty.pp.sci.fi>
* Added "SET OPTION CHARACTER SET cp1251_koi8" to enable conversions off
data to/from different character sets. Currently cp1251_koi8 is the only
one, but it's now trivial to add others.
Conversions: strings in the query -> intern set
fields and items in result -> terminal set
One can get back to the old one with:
SET OPTION CHARACTER SET DEFAULT
* Lots of changes for Win95 port
Fri Oct 17 15:29:44 1997 <monty@monty.pp.sci.fi>
* Changed the create column syntax off NOT NULL to be after the DEFAULT value
as specified in the ANSI SQL standard. This will make mysqldump with
NOT NULL and default values incompatible with MySQL 3.20.
* New reserved words are: BOTH, FOR, LEADING and TRAILING
* Added a lot of function name alias so one can use the functions with
ODBC or ANSI SQL92 syntax.
* Fixed ALTER TABLE person ALTER COLUMN phone SET DEFAULT NULL syntax.
* Added CHAR and BIT as a synonyms for CHAR(1)
* Changed the name if the INTERVAL type to ENUM, because INTERVAL is used in
ANSI SQL.
* Added extended ANSI SQL TRIM() function.
* Added CURTIME().
Thu Oct 16 17:26:48 1997 <monty@monty.pp.sci.fi>
* Fixed core dump when updating as user with only select privilige.
Wed Oct 15 04:25:47 1997 <monty@monty.pp.sci.fi>
* INSERT ... SELECT ... GROUP BY didn't work in some cases. On got
'Invalid use of group function'
* When using LIMIT, SELECT now always uses keys instead of record scan.
This will give better performance on SELECT and a WHERE that matches many
rows.
* Added function last_insert_id() to retreive last auto_increment value.
This is for clients to ODBC that can't use the mysql_insert_id API function.
* Added option '--flush-logs' to mysqladmin.
* Added command 'status' to mysql.
* Moved some messages from libmysql.c to errmsg.c
Mon Oct 13 18:38:01 1997 <monty@monty.pp.sci.fi>

Tue Sep 30 02:40:42 1997 <monty@monty.pp.sci.fi>
* Added new function: REPEAT(string,count).
* Added patch of support of Chinese(BIG5).
* Fixed awful slowdown of libmysql.c when configuring using '--with-debug=yes'
This affected all clients that got large results from the server.
(This didn't affect using --quick or mysql_use_result).
Sun Sep 28 20:59:41 1997 <monty@monty.pp.sci.fi>
* Made a new function: mysql_real_connect, that takes two extra arguments:
port and socket to use on connection.
* Added text types: TINYTEXT, TEXT, MIDDLETEXT and LONGTEXT.
These are actually blobs, but all searching is done text independent.
All old BLOB fields are now TEXT fields.
* LONG VARCHAR is a synonym for TEXT. LONG BINARY is a synonym for BLOB.
* 'LONG' is now a reserved word.
Fri Sep 26 16:11:34 1997 <monty@monty.pp.sci.fi>
* Release of 3.21.9
* Fixed a couple of portable problems with include files.

set when searching on multiple key with only one entry (very rare).
Wed Sep 24 15:51:37 1997 <monty@monty.pp.sci.fi>
* Changed thread scope from PROCESS to SYSTEM. This should give better
scheduling (performance) on Solaris.
* Fixed duplicated free bug in sql_base with io_cache.

Mon Sep 22 14:54:00 1997 <monty@monty.pp.sci.fi>
* mysql_fetch_lengths() returned sometimes wrong lengths when one used
mysql_use_result(). This affected at least some cases of mysqldump --quick.
Sun Sep 21 20:50:07 1997 <monty@monty.pp.sci.fi>
* Fixed memory leak bug in range optimizer.
Sat Sep 20 00:03:51 1997 <monty@monty.pp.sci.fi>

* Fixed bug in optimization of WHERE const op field.
Fri Sep 19 12:06:37 1997 <monty@monty.pp.sci.fi>
* Fixed problem when sorting on NULL fields.
* Added handling of calculation of sum() functions.
* Added handling of trigometric functions: PI(), ACOS(), ASIN(), ATAN(),
COS(), SIN() and TAN().

argument).
Thu Aug 21 16:40:21 1997 <monty@monty.pp.sci.fi>
* Version 3.21.6
* Enabled range optimizer for update and delete. Now update and delete can
use keys again.
* Fixed bug when using unknown field in group clause.
Tue Aug 19 00:49:13 1997 <monty@monty.pp.sci.fi>
* The range optimizer is now enabled as default. Use msyqld --skip-new
to disable it.
* numerous small fixes to the range optimzer and a couple if fixes to
group and where handling.
* Added patch from JOERG_HENNE@Non-HP-Germany-om88.om.hp.com to allow
mit-threads to work on HPUX10. (This patch is regarded alpha)
Fri Aug 15 02:29:21 1997 <monty@monty.pp.sci.fi>
* Remove reverse lookup of hostnames because this takes 2 seconds
one some machines for every connection!
This can be enabled with the --secure option to mysqld.
Thu Aug 14 22:40:15 1997 <monty@monty.pp.sci.fi>

YYYY-MM-DD HH:MM:DD format.
* New function sec_to_time(seconds) which returns a string in H:MM:SS format.
Sat Aug 2 17:18:22 1997 <monty@monty.pp.sci.fi>
* Fixed some porting issues for OSF1 and for Alpha.
Now MySQL is know to configure on OSF1 with the Dec compiler,
after changeing one line in config.h:
#define SOCKET_SIZE_TYPE int
Wed Jul 30 11:05:39 1997 <monty@monty.pp.sci.fi>
* Added reverse check lookup of hostnames to get better security.
* Fixed some possible buffer overflows if one uses too long filenames.
* mysqld doesn't accept hostnames that starts with digits followed by a '.'
because the hostname may look like a IP.
* Added option --skip-networking to only allow socket connections.
(This will not work with MIT threads!)
Tue Jul 29 10:38:55 1997 Michael Widenius <monty@monty.pp.sci.fi>
* Removed wrong free() that killed the server on 'create/drop database'.
* Changed the name of some mysqld -O options to better names.
* Added option '-O join_cache_size=#'.
* Added option '-O max_join_size=#' to be able to set a limit how big queries
(in this case big = slow) one should be able to handle without specifying
'SQL_OPTION OPTION_BIG_SELECTS=1'.
A # = is about 10 examined records. The default is 'unlimited'.
* When comparing a TIME, DATE, DATETIME or TIMESTAMP column to a
constant the constant is converted to a time value before comparing.
This will make it easier to get ODBC and particularly Access97 to work with
the above types. It should also make dates easier to use and the compares
should be quicker than before.
* added check of too long table names for alias.
Mon Jul 21 16:09:47 1997 Michael Widenius <monty@monty.pp.sci.fi>
* Applied patch from Jochen Wiedmann that fixes that query() in mysqlperl now
can take queries with \0 in it.
Sat Jul 19 01:11:38 1997 Michael Widenius <monty@monty.pp.sci.fi>
* Store of timestamp with 2 digit year YYMMDD didn't work.
* Fix that timestamp isn't automaticly updated if set in a update clause.
* Now the automatic timestamp field is the FIRST timestamp field.
Thu Jul 3 13:34:26 1997 <monty@monty.pp.sci.fi>
* Added check if database name is okey.
* Addded check if too long table names.

* mysqladmin: One can now do 'mysqladmin kill 5,6,7,8'
* Fixed 'Packets out of order' message. This error come sometimes when the
server was out of threads/memory. Now the correct message is retrieved by
the client.
* Added more checks with thread create for 'out of memory' errors.
* Added more checks if threads is killed to get faster kill.
* Changed the default record cache from 512K to 128K to get less problem on
systems with little memory.

SELECT DISTINCT MOD(some_field,10) FROM test GROUP BY some_field;
* Increased max packet size from 512K to 1024K for client.
* Removed a lot of unused functions
Mon Jun 23 22:58:07 1997 <monty@monty.pp.sci.fi>
* Changed key_parts to have own field for shortened keys. This gives much
nicer code in select.
Thu Jun 19 13:09:14 1997 <monty@monty.pp.sci.fi>
* ALTER TABLE now returns warnings from field conversions.
Changed all numerical fields to check for correct number and
increment warning counts if the value is wrong.
Wed Jun 18 22:14:36 1997 <monty@monty.pp.sci.fi>
* Fixed buffer overflow when retrieving big packets.
Tue Jun 17 03:26:27 1997 <monty@monty.pp.sci.fi>
* Port changed to 3306 (got it reserved from ISI).
Mon Jun 16 15:46:42 1997 <monty@monty.pp.sci.fi>
* All double are now rounded before storad as integer values.
* Fixed bug when using: SELECT WHERE A=const1 OR A=const2 OR A=const3,
and const1 = const3. In this case a key over A=const1 was wrongly used and
A=const2 wasn't used.
* Added a fix for Visual Fox Base so that any schema name from a table
specification is automaticly removed.
Sun Jun 15 12:47:23 1997 <monty@monty.pp.sci.fi>
* The thr_alarm array is now initialized based on number of connections
* Changed some memcpy() to bmove() to get rid of some warnings from purify.
* Changed the sql_yacc.c to drop schema name from table name. This is a crude
patch to get VFP
Sat Jun 14 12:04:59 1997 <monty@monty.pp.sci.fi>
* fixed missed ptr variable in filesort.
* Fixed wrong tablename and record count EXPLAIN.
