These are the developers that are or have been employed by MySQL AB

While MySQL AB owns all copyrights in the MySQL server
and the MySQL manual, we wish to recognize those who have made
contributions of one kind or another to the MySQL distribution.
Contributors are listed here, in somewhat random order:
Win32 port with Borland compiler. mysqlshutdown.exe and
mysqlwatch.exe
David J. Hughes
For the effort to make a shareware SQL database. At TcX, the predecessor
of MySQL AB, we started with mSQL, but found that it couldn't
satisfy our purposes so instead we wrote an SQL interface to our
application builder Unireg. mysqladmin and mysql client are
programs that were largely influenced by their mSQL counterparts.
We have put a lot of effort into making the MySQL syntax a superset of
mSQL. Many of the API's ideas are borrowed from mSQL to
make it easy to port free mSQL programs to the MySQL API.
The MySQL software doesn't contain any code from mSQL.
Two files in the distribution (`client/insert_test.c' and
`client/select_test.c') are based on the corresponding (non-copyrighted)
files in the mSQL distribution, but are modified as examples showing
the changes necessary to convert code from mSQL to MySQL Server.
(mSQL is copyrighted David J. Hughes.)
Ported (and extended) the benchmark suite to DBI/DBD. Have
been of great help with crash-me and running benchmarks. Some new
date functions. The mysql_setpermission script.
Configure updates for Tru64, large file support and better TCP wrappers
support.
John Birrell
Emulation of pthread_mutex() for OS/2.
Benjamin Pflugmann
Extended MERGE tables to handle INSERTS. Active member
on the MySQL mailing lists.
Jocelyn Fournier
Excellent spotting and reporting innumerable bugs
(especially in the MySQL 4.1 subquery code).
Marc Liyanage
Maintaining the Mac OS X packages and providing invaluable feedback
on how to create Mac OS X PKGs.
Robert Rutherford
Providing invaluable information and feedback about the QNX port.
Previous developers of NDB Cluster
Lots of people were involved in various ways summer students, master thesis
students, employees. In total more than 100 people so too many to mention here.
Notable name is Ataullah Dabaghi who up until 1999 contributed around a
third of the code base. A special thanks also to developers of the AXE system
which provided much of the architecturial foundations for NDB Cluster with
blocks, signals and crash tracing functionality. Also credit should be given
to those who believed in the ideas enough to allocate of their budgets for its
development from 1992 to present time.
The following people has helped us with writing the MySQL documentation and
translating the documentation or error messages in MySQL.
Paul DuBois
Ongoing help with making this manual correct and understandable.
That includes rewriting Monty's and David's attempts at English into
English as other people know it.
Kim Aldale
Helped to rewrite Monty's and David's early attempts at English into English.
The following is a list of the creators of the libraries we have
included with the MySQL server source to make it easy to compile and
install MySQL. We are very thankfully to all individuals that have
created these and it has made our life much easier.
Fred Fish
For his excellent C debugging and trace library. Monty has made a number
of smaller improvements to the library (speed and additional options).
Richard A. O'Keefe
For his public domain string library.
Henry Spencer
For his regex library, used in WHERE column REGEXP regexp.
Chris Provenzano
Portable user level pthreads. From the copyright: This product includes
software developed by Chris Provenzano, the University of California,
Berkeley, and contributors. We are currently using version 1_60_beta6
patched by Monty (see `mit-pthreads/Changes-mysql').
Jean-loup Gailly and Mark Adler
For the zlib library (used on MySQL on Windows).
Bjorn Benson
For his safe_malloc (memory checker) package which is used in when you
configure MySQL with --debug.
Free Software Foundation
The readline library (used by the mysql command-line client).
The NetBSD foundation
The libedit package (optionally used by the mysql command-line
client).
The following is a list of creators/maintainers of some of the most
important API/packages/applications that a lot of people use with MySQL.
We can't list every possible package here because the list would then be
way to hard to maintain. For other packages, please refer to the
software portal at http://solutions.mysql.com/software/.
The following is a list of some of the tools we have used to create MySQL.
We use this to express our thanks to those that has created them as without
these we could not have made MySQL what it is today.
Free Software Foundation
From whom we got an excellent compiler (gcc), an excellent
debugger (gdb and the libc library (from which we have
borrowed `strto.c' to get some code working in Linux).
Free Software Foundation & The XEmacs development team
For a really great editor/environment used by almost everybody at
MySQL AB.
Julian Seward
Author of valgrind, an excellent memory checker tool that has helped
us find a lot of otherwise hard to find bugs in MySQL.
Dorothea Lütkehaus and Andreas Zeller
For DDD (The Data Display Debugger) which is an excellent
graphical frontend to gdb).
While MySQL AB owns all copyrights in the MySQL server
and the MySQL manual, we wish to recognize the following companies,
which helped us finance the development of the MySQL server,
such as by paying us for developing a new feature or giving us hardware
for development of the MySQL server.
VA Linux / Andover.net
Funded replication.
NuSphere
Editing of the MySQL manual.
Stork Design studio
The MySQL Web site in use between 1998-2000.
Intel
Contributed to development on Windows and Linux platforms.
