G.2. Contributors to MySQL
Although 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 architectural 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 have 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.
Dutch error messages, completing earlier partial translation
(also work on consistency and spelling).
G.4. Libraries used by and included with MySQL
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).
G.5. Packages that support MySQL
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 author of LinuxThreads (used by the MySQL Server on
Linux).
G.6. Tools that were used to create MySQL
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 front end to
gdb).
G.7. Supporters of MySQL
Although 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.
