GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

Basic Installation
==================
These are generic installation instructions.
The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation. It uses
those values to create a `Makefile' in each directory of the package.
It may also create one or more `.h' files containing system-dependent
definitions. Finally, it creates a shell script `config.status' that
you can run in the future to recreate the current configuration, a file
`config.cache' that saves the results of its tests to speed up
reconfiguring, and a file `config.log' containing compiler output
(useful mainly for debugging `configure').
If you need to do unusual things to compile the package, please try
to figure out how `configure' could check whether to do them, and mail
diffs or instructions to the address given in the `README' so they can
be considered for the next release. If at some point `config.cache'
contains results you don't want to keep, you may remove or edit it.
The file `configure.in' is used to create `configure' by a program
called `autoconf'. You only need `configure.in' if you want to change
it or regenerate `configure' using a newer version of `autoconf'.
The simplest way to compile this package is:
1. `cd' to the directory containing the package's source code and type
`./configure' to configure the package for your system. If you're
using `csh' on an old version of System V, you might need to type
`sh ./configure' instead to prevent `csh' from trying to execute
`configure' itself.
Running `configure' takes awhile. While running, it prints some
messages telling which features it is checking for.
2. Type `make' to compile the package.
3. Optionally, type `make check' to run any self-tests that come with
the package.
4. Type `make install' to install the programs and any data files and
documentation.
5. You can remove the program binaries and object files from the
source code directory by typing `make clean'. To also remove the
files that `configure' created (so you can compile the package for
a different kind of computer), type `make distclean'. There is
also a `make maintainer-clean' target, but that is intended mainly
for the package's developers. If you use it, you may have to get
all sorts of other programs in order to regenerate files that came
with the distribution.
Compilers and Options
=====================
Some systems require unusual options for compilation or linking that
the `configure' script does not know about. You can give `configure'
initial values for variables by setting them in the environment. Using
a Bourne-compatible shell, you can do that on the command line like
this:
CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
Or on systems that have the `env' program, you can do it like this:
env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
Compiling For Multiple Architectures
====================================
You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory. To do this, you must use a version of `make' that
supports the `VPATH' variable, such as GNU `make'. `cd' to the
directory where you want the object files and executables to go and run
the `configure' script. `configure' automatically checks for the
source code in the directory that `configure' is in and in `..'.
If you have to use a `make' that does not supports the `VPATH'
variable, you have to compile the package for one architecture at a time
in the source code directory. After you have installed the package for
one architecture, use `make distclean' before reconfiguring for another
architecture.
Installation Names
==================
By default, `make install' will install the package's files in
`/usr/local/bin', `/usr/local/man', etc. You can specify an
installation prefix other than `/usr/local' by giving `configure' the
option `--prefix=PATH'.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If you
give `configure' the option `--exec-prefix=PATH', the package will use
PATH as the prefix for installing programs and libraries.
Documentation and other data files will still use the regular prefix.
In addition, if you use an unusual directory layout you can give
options like `--bindir=PATH' to specify different values for particular
kinds of files. Run `configure --help' for a list of the directories
you can set and what kinds of files go in them.
If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving `configure' the
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
Optional Features
=================
Some packages pay attention to `--enable-FEATURE' options to
`configure', where FEATURE indicates an optional part of the package.
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
is something like `gnu-as' or `x' (for the X Window System). The
`README' should mention any `--enable-' and `--with-' options that the
package recognizes.
For packages that use the X Window System, `configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the `configure' options `--x-includes=DIR' and
`--x-libraries=DIR' to specify their locations.
Specifying the System Type
==========================
There may be some features `configure' can not figure out
automatically, but needs to determine by the type of host the package
will run on. Usually `configure' can figure that out, but if it prints
a message saying it can not guess the host type, give it the
`--host=TYPE' option. TYPE can either be a short name for the system
type, such as `sun4', or a canonical name with three fields:
CPU-COMPANY-SYSTEM
See the file `config.sub' for the possible values of each field. If
`config.sub' isn't included in this package, then this package doesn't
need to know the host type.
If you are building compiler tools for cross-compiling, you can also
use the `--target=TYPE' option to select the type of system they will
produce code for and the `--build=TYPE' option to select the type of
system on which you are compiling the package.
Sharing Defaults
================
If you want to set default values for `configure' scripts to share,
you can create a site shell script called `config.site' that gives
default values for variables like `CC', `cache_file', and `prefix'.
`configure' looks for `PREFIX/share/config.site' if it exists, then
`PREFIX/etc/config.site' if it exists. Or, you can set the
`CONFIG_SITE' environment variable to the location of the site script.
A warning: not all `configure' scripts look for a site script.
Operation Controls
==================
`configure' recognizes the following options to control how it
operates.
`--cache-file=FILE'
Use and save the results of the tests in FILE instead of
`./config.cache'. Set FILE to `/dev/null' to disable caching, for
debugging `configure'.
`--help'
Print a summary of the options to `configure', and exit.
`--quiet'
`--silent'
`-q'
Do not print messages saying which checks are being made. To
suppress all normal output, redirect it to `/dev/null' (any error
messages will still be shown).
`--srcdir=DIR'
Look for the package's source code in directory DIR. Usually
`configure' can determine that directory automatically.
`--version'
Print the version of Autoconf used to generate the `configure'
script, and exit.
`configure' also accepts some other, not widely useful, options.

Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
The Free Software Foundation has exempted Bash from the requirement of
Paragraph 2c of the General Public License. This is to say, there is
no requirement for Bash to print a notice when it is started
interactively in the usual way. We made this exception because users
and standards expect shells not to print such messages. This
exception applies to any program that serves as a shell and that is
based primarily on Bash as opposed to other GNU software.

these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
Appendix: How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) 19yy <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) 19yy name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

Introduction:
The Flexible Filesystem Benchmark (FFSB) is a filesystem performance
measurement tool. It is a multi-threaded application (using
pthreads), written entirely in C with cross-platform portability in
mind. It differs from other filesystem benchmarks in that the user
may supply a profile to create custom workloads, while most other
filesystem benchmarks use a fixed set of workloads.
As of version 5.1, it supports seven different basic operations, support
for multiple groups of threads with different operation mixtures,
support for operation across multiple filesystems, and support for
filesystem aging prior to benchmarking.
Differences from version 4.0 and older:
Version 5.0 and above represent almost a total re-write and many
things have changed. In version 5.0 and above FFSB moved to a
time-regulated run versus doing a set number of different operations
and timing the whole thing. This is primarily to better deal with the
use of multiple threadgroups which would otherwise not be synchronized
at termination time.
Additionally, the FFSB configuration file format has changed in
version 5.0, although we do support old-style configuration files
along with a run-time passed on the command line. In this mode,
version 5.0 and above ignores the iterations parameter, and simply
uses the time specified on the command line.
Behaviorally, most of the old operations are the same -- sequential
reads and sequential writes work as they did before. One change in
version 5.0 is the skip-read behavior of reading then seeking forward
a fixed amount then reading again is removed, we now support fully
randomized reads and writes from random offsets within the file.
Version 4.0 didn't support overwrites (only appends) so we interpret
writes in old config files to be append operations.
On Linux, CPU utilization information will only be accurate for
systems using NPTL, older Linuxthreads systems will probably only see
zeros for CPU utilization because Linuxthreads is non-compliant to
POSIX. Version 4.0 and older could be recompiled to work on
Linuxthreads, but in 5.0 and later we no longer support this.
We no longer support the "outputfile" on the command line.
One should simply use tee or similar to capture the output. FFSB
unbuffers standard out for this purpose, and errors are sent on
standard error.
Global options:
There are eight valid global options placed at the beginning of the
profile. Three of them are required: num_filesystems (number of
filesystems), num_threadgroups (number of threadgroups), and time
(running time of the benchmark). The other five options are:
directio - each call to open will be made using O_DIRECT
alignio - aligns all block operations for random reads and writes
on 4k boundaries.
bufferedio - currently ignorred: it is intended to use libc
fread,rwrite, instead of just unix read and write calls
verbose - currently ignored
callout - calls and external command and waits for its termination
before FFSB begins the benchmark phase.
This is useful for synchronizing distributed clients,
starting profilers, etc.
They must be specified in the above order (num_filesystems,
num_threadgroups, time, directio, alignio, bufferedio, verbose,
callout).
Filesystems:
Filesystems are specified to FFSB in the form of a directory. FFSB
assumes that the filesystem is mounted at this directory and will not
do any verification of this fact beyond ensuring it can read/write to
the location. So be careful to ensure something with enough space to
handle the dataset is in fact mounted at the specified location.
In the filesystem clause of the profile, one may set the starting
number of files and directories as well as a minimum and maximum
filesize for the filesystem. One may also specify the blocksize
used for creating the files separately in the filesystem clause.
Also, if a filesystem is to be aged, a special threadgroup clause may
be embedded in a filesystem clause to specify the operation mixture
and number of threads used to age the filesystem. This threadgroup is
run until filesystem utilization reaches the specified amount.
Inheritance -- if you are using multiple filesystems, all attributes
except the location should be inherited from the previous filesystem.
This is done to make it easier to add groups of similar filesystems.
In this case, only the location is required in the filesystem clause.
As of version 5.1, filesystem re-use is supported if a given
filesystem hasn't been modified beyond it's orginal specifications
(number of files and directories is correct, and file sizes are within
specifications). This can be a huge time saver if one wishes to do
multiple runs on the same data-set without altering it during a run,
because the fileset doesn't need to be recreated before each run.
To do this, specify "reuse=1" in the filesystem clause, and FFSB will
verify the fileset first, and if it checks out it will use it.
Otherwise, it will remove everything and re-create the filesets for
that filesystem.
Threadgroups:
An arbitrary number of threadgroups with differing numbers of threads
and operation mixes can be specified. The operations are specified
using a weighting for each operation, if an operation isn't specified
it's weighting is assumed to be zero (not used).
"Think-time" for a threadgroup may also be specified in millisecond
amounts using the "op_delay" parameter, where every thread will wait
for the specified amount between each operation.
Operations:
All operations begin by randomly selecting a filesystem from the list
of filesystems specified in the profile. The distribution aims to be
uniform across all filesystems.
The seven operations are:
reads - read() calls with an overall amount and a blocksize
operates on existing files. Care must be taken to ensure
that the read amount is smaller than the size of any possible
file.
If random_read is specified, then the each individual blocks
will be read starting from a random point with the file, and
this will continune until the entire amount specifed has been
read. This offset of each random block will be totally
random to the byte level, unless the "alignio" global parameter
is on, and then the reads will be 4096 byte aligned. This is
generally recommended.
readall - Very similar to read above, except it doesn't take an
amount; it simply reads the entire file sequentially using the
read_blocksize. This is useful for situations where
different filesystems have differently sized files, and sequential
read patterns across all filesystems are desired.
writes - write() calls with an overall amount and blocksize
this is an overwrite operation and will not enlarge an existing
file, again one must be careful not to specify a write amount
that is larger than any possible file in the data set.
If random_write is specified, then the each individual blocks
will be written starting from a random point with the file, and
this will continune until the entire amount specifed has been
written out. This offset of each random block will be totally
random to the byte level, unless the "alignio" global parameter
is on, and then the writes will be 4096 byte aligned. This
is generally recommended.
If the fsync_flag parameter for the threadgroup is non-zero,
then after all of the write calls are finished, fsync() will
be called on the file descriptor before the file is closed.
creates - creates a file using open() call and determines the size
randomly between on the constraints (min_filesize and
max_filesize) for the selected filesystem. Write operations will
be done using the same blocksize as is specified for the
write operation.
deletes - calls unlink() on a filename and removes it from the
internal data-structures. One must be careful to ensure
there are enough files to delete at all times or else the benchmark
will terminate.
appends - calls write() using the append flag with an overall amount
and a blocksize to be appended onto a randomly chosen file.
metas - this is actually a mix of several different directory
operations. Each "meta" operation consists of two directory
creates, one directory remove, and a directory rename.
These operations are all carried out separately from the
other 5 operations.
Operation accounting:
Each operation which uses a blocksize counts each read/write of a
blocksize as an operation (reads,writes,creates, and appends) whereas
deletes and metas are considered single operations.
Running the benchmark:
There are three phases to running the benchmark, aging, fileset
creates, and the benchmark phase.
The create phase is carried out across all filesystems simultanously
with one dedicated thread per filesystem.
After the create phase, sync() is called to ensure all dirty data gets
written out before the benchmark phase begins, and sync() is again
called at the end of the benchmark phase. The time in sync() at the
end of the benchmark phase is counted as part of the benchmark phase.
Caveats/Holes/Bugs:
Aging and aging across multiple filesystems simultaneously hasn't been tested
very much.
If *any* i/o operation or system call/libc call fails, the benchmark
will terminate immediately.
The parser doesn't handle mal-formed or incorrect profiles very well
(or at all).
The parser doesn't check to make sure all of the appropriate options
have been specified. For example, if writes are specified in a
threadgroup but write_blocksize isn't specified, the parse won't catch
it, but the benchmark run will fail later on.
Configuration Files (new style):
New Style Configuration allows for arbitrary newlines between lines,
and comments using '#' at the start of a line. Also it allows tabs,
whitespace before and after configuration parameters.
The new style configuration file is broken up into three main parts:
global parameters, filesystems, and threadgroups
The sections must be in the above order.
Global parameters:
Global Paramters are described above, the first three are always
required. Example:
----------
num_filesystems=1
num_threadgroups=1
time=30 # time is in seconds
directio=0 # don't use direct io
alignio=1 # align random IOs to 4k
bufferedio=0 # this does nothing right now
verbose=0 # this does nothing right now
# calls and external command and waits
# everything until the newline is taken
# so you can have abritrary parmeters
callout=synchronize.sh myhostname
---------
All of these must appear in this order, though you can leave out the
optional ones.
Filesystems:
Filesystems describe differnt logical sets of files residing in
different directorys. There is no strict requirement that they
actually be on different filesystems, only that the directory
specified already exists.
Filesystems are specified by a clause with a filesystem number like
this:
[filesystem0]
location=/mnt/testing/
num_files=10
num_dirs=1
max_filesize=4096
min_filesize=4096
[end0]
The clause must always begin with [filesystemX] and end with [endX]
where X is the number of that filesystem.
You should start wiht X = 0, and increment by one for each following
filesystem. If they are out of order, things will likely break.
The required information for each filesystem is: location, num_files,
num_dirs, max_filesize, and min_filesize. Beyond those the following
four options are supported:
reuse=1 # check the filesystem to see if it is reusable
# filesystem aging, three components required
# takes agefs=1 to turn it on
# then a valid threadgroup specification
# then a desired utilization percentage
agefs=1 # age the filesystem according to the following threadgroup
[threadgroup0]
num_threads=10
write_size=40960
write_blocksize=4096
create_weight=10
append_weight=10
delete_weight=1
[end0]
desired_util=0.20 # In this case, age until the fs is 20% full
create_blocksize=4096 # specify the blocksize to write()
# for creating the fileset, defaults to 4096
age_blocksize=4096 # specify the blocksize to write() for aging
Also, to allow lazy people to use lots of filesystems, we support
filesystem inheritance, which simply copies all options but the
location from the previous filesystem clause if nothing is specified.
Obviously, this doesn't work for filesystem0. (May not work for aging
either?)
Full blown filesystem clause example:
----
[filesystem0]
# required parts
location=/home/sonny/tmp
num_files=100
num_dirs=100
max_filesize=65536
min_filesize=4096
# aging part
agefs=0
[threadgroup0]
num_threads=10
write_size=40960
write_blocksize=4096
create_weight=10
append_weight=10
delete_weight=1
[end0]
desired_util=0.02 # age until 2% full
# other optional commands
create_blocksize=1024 # use a small create blocksize
age_blocksize=1024 # and smaller age create blocksize
reuse=0 # don't reuse it
[end0]
--
Threadgroups:
Threadgropus are very similar to filesystems in that any number of
them can be specified in clauses, and they must be in order starting
with threadgroup0.
Example:
---
[threadgroup0]
num_threads=32
read_weight=4
append_weight=1
write_size=4096
write_blocksize=4096
read_size=4096
read_blocksize=4096
[end0]
---
In a threadgroup clause, num_threads is required and must be at least
1. Then, at least one operation must be given a weight greater than 0
to be a valid threadgroup. Operations can be given a weighting of 0,
and in this case they are ignored.
Certain operations will also require other commands, for example, if
read_weight is greater than zero, then one must also include a
read_size and a read_blocksize. Here's the table of requirements and
options:
Operation Requirements Options
-- -- --
read_weight read_size, read_blocksize read_random
readall_weight read_blocksize none
write_weight write_size, write_blocksize write_random,fsync_file
create_weight write_blocksize or create_blocksize none
append_weight write_blocksize, write_size none
delete_weight none none
meta_weight none none
Other threadgroup options:
op_delay=10 # specify a wait between operations in milli-seconds
bindfs=3 # This allows you to restrict a threadgroup's operation
# to a specific filesystem number. Currently only
# binding to one specific filesystem is supported

#
# Of course, Automake must honor this variable whenever it calls a
# tool from the auxiliary directory. The problem is that $srcdir (and
# therefore $ac_aux_dir as well) can be either absolute or relative,
# depending on how configure is run. This is pretty annoying, since
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
# source directory, any form will work fine, but in subdirectories a
# relative path needs to be adjusted first.
#
# $ac_aux_dir/missing
# fails when called from a subdirectory if $ac_aux_dir is relative
# $top_srcdir/$ac_aux_dir/missing
# fails if $ac_aux_dir is absolute,
# fails when called from a subdirectory in a VPATH build with
# a relative $ac_aux_dir
#
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
# are both prefixed by $srcdir. In an in-source build this is usually
# harmless because $srcdir is `.', but things will broke when you
# start a VPATH build or use an absolute $srcdir.
#
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
# and then we would define $MISSING as
# MISSING="\${SHELL} $am_aux_dir/missing"
# This will work as long as MISSING is not called from configure, because
# unfortunately $(top_srcdir) has no meaning in configure.
# However there are other variables, like CC, which are often used in
# configure, and could therefore not use this "fixed" $ac_aux_dir.
#
# Another solution, used here, is to always expand $ac_aux_dir to an
# absolute PATH. The drawback is that using absolute paths prevent a
# configured tree to be moved without reconfiguration.

# AM_PROG_INSTALL_STRIP
# ---------------------
# One issue with vendor `install' (even GNU) is that you can't
# specify the program used to strip binaries. This is especially
# annoying in cross-compiling environments, where the build's strip
# is unlikely to handle the host's binaries.
# Fortunately install-sh will honor a STRIPPROG variable, so we
# always use install-sh in `make install-strip', and initialize
# STRIPPROG with the value of the STRIP variable (set by the user).

## up in a subdir. Having to rename by hand is ugly.
## (We might end up doing this anyway to support other compilers.)
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
## -MM, not -M (despite what the docs say).
## - Using -M directly means running the compiler twice (even worse

## This next piece of magic avoids the `deleted header file' problem.
## The problem is that when a header file which appears in a .P file
## is deleted, the dependency causes make to die (because there is
## typically no way to rebuild the header). We avoid this by adding
## dummy dependencies for each header file. Too bad gcc doesn't do
## this for us directly.

* The thread group is responsible for creating the ffsb_thread

* operation and a filesystem to run that operation on. The thread
* objects don't contain any of the configuration information.
*
* Thread groups are also abstracted so they can be "run" arbitrarily
* which is useful because we can reuse them for aging. The running
* is a bit complex, the thread group has to have a callback function
* which is runs at a specified interval to determine when to
* terminate.
*
* To synchronize starting across many thread groups there are two
* barriers used, the first one "tg_barrier" in the run_params is to
* synchronize multiple thread-groups being ready to start, meaning
* that all their threads have been spawned The second one
* "thread_barrier" synchronizes all threads across multiple thread
* groups, so that they all start at once.

* Container class for a red-black tree ......
*
* A binary tree that satisfies the following properties:
*
* 1. Every node is either red or black
* 2. The root node is black
* 3. Every leaf (NIL) is black
* 4. If a node is red, both its children are black
* 5. For each node, all paths from the node to descendant leaf nodes
* contain the same number of black nodes
*
* Due to points 4 & 5, the depth of a red-black tree containing n nodes
* is bounded by 2*log2(n+1) (WC).
*
*
* The rb_tree template requires two additional parmeters:
*
* - The contained TYPE class represents the objects stored in the tree.
* It has to support the copy constructor and the assignment operator (opr)
* - cmp is a functor used to define the order of objects of class TYPE:
* This class has to support an operator() that recieves two objects from
* the TYPE class and returns a negative, 0, or a positive integer,
* depending on the comparison result.

The Flexible Filesystem Benchmark (FFSB) is a filesystem performance measurement tool. It is a multi-threaded application (using pthreads), written entirely in C with cross-platform portability in mind. It differs from other filesystem benchmarks in that the user may supply a profile to create custom workloads, while most other filesystem benchmarks use a fixed set of workloads.
It is currently known to support Linux, AIX, and Solaris, although almost all development and testing has occurred on Linux. We intend to add support for HP-UX, IRIX, and possibly others in the near future.
FFSB is currently at version 5.0, and has been an internal tool at IBM for about four years. I has already been used to conduct a study of Linux Kernel 2.6 IO-schedulers, and a great deal of future filesystem performance work is planned with FFSB as the primary tool.
In version 5.0, it supports six different basic operations, support for multiple groups of threads with different operation mixtures, support for operation across multiple filesystems, and support for filesystem aging prior to benchmarking.
