Authors of XZ Utils
|
||||
===================
|
||||
|
||||
XZ Utils is developed and maintained by Lasse Collin
|
||||
<lasse.collin@tukaani.org>.
|
||||
|
||||
Major parts of liblzma are based on code written by Igor Pavlov,
|
||||
specifically the LZMA SDK <http://7-zip.org/sdk.html>. Without
|
||||
this code, XZ Utils wouldn't exist.
|
||||
|
||||
The SHA-256 implementation in liblzma is based on the code found from
|
||||
7-Zip <http://7-zip.org/>, which has a modified version of the SHA-256
|
||||
code found from Crypto++ <http://www.cryptopp.com/>. The SHA-256 code
|
||||
in Crypto++ was written by Kevin Springle and Wei Dai.
|
||||
|
||||
Some scripts have been adapted from gzip. The original versions
|
||||
were written by Jean-loup Gailly, Charles Levert, and Paul Eggert.
|
||||
Andrew Dudman helped adapting the scripts and their man pages for
|
||||
XZ Utils.
|
||||
|
||||
The GNU Autotools-based build system contains files from many authors,
|
||||
which I'm not trying to list here.
|
||||
|
||||
Several people have contributed fixes or reported bugs. Most of them
|
||||
are mentioned in the file THANKS.

XZ Utils Licensing
|
||||
==================
|
||||
|
||||
Different licenses apply to different files in this package. Here
|
||||
is a rough summary of which licenses apply to which parts of this
|
||||
package (but check the individual files to be sure!):
|
||||
|
||||
- liblzma is in the public domain.
|
||||
|
||||
- xz, xzdec, and lzmadec command line tools are in the public
|
||||
domain unless GNU getopt_long had to be compiled and linked
|
||||
in from the lib directory. The getopt_long code is under
|
||||
GNU LGPLv2.1+.
|
||||
|
||||
- The scripts to grep, diff, and view compressed files have been
|
||||
adapted from gzip. These scripts and their documentation are
|
||||
under GNU GPLv2+.
|
||||
|
||||
- All the documentation in the doc directory and most of the
|
||||
XZ Utils specific documentation files in other directories
|
||||
are in the public domain.
|
||||
|
||||
- Translated messages are in the public domain.
|
||||
|
||||
- The build system contains public domain files, and files that
|
||||
are under GNU GPLv2+ or GNU GPLv3+. None of these files end up
|
||||
in the binaries being built.
|
||||
|
||||
- Test files and test code in the tests directory, and debugging
|
||||
utilities in the debug directory are in the public domain.
|
||||
|
||||
- The extra directory may contain public domain files, and files
|
||||
that are under various free software licenses.
|
||||
|
||||
You can do whatever you want with the files that have been put into
|
||||
the public domain. If you find public domain legally problematic,
|
||||
take the previous sentence as a license grant. If you still find
|
||||
the lack of copyright legally problematic, you have too many
|
||||
lawyers.
|
||||
|
||||
As usual, this software is provided "as is", without any warranty.
|
||||
|
||||
If you copy significant amounts of public domain code from XZ Utils
|
||||
into your project, acknowledging this somewhere in your software is
|
||||
polite (especially if it is proprietary, non-free software), but
|
||||
naturally it is not legally required. Here is an example of a good
|
||||
notice to put into "about box" or into documentation:
|
||||
|
||||
This software includes code from XZ Utils <http://tukaani.org/xz/>.
|
||||
|
||||
The following license texts are included in the following files:
|
||||
- COPYING.LGPLv2.1: GNU Lesser General Public License version 2.1
|
||||
- COPYING.GPLv2: GNU General Public License version 2
|
||||
- COPYING.GPLv3: GNU General Public License version 3
|
||||
|
||||
Note that the toolchain (compiler, linker etc.) may add some code
|
||||
pieces that are copyrighted. Thus, it is possible that e.g. liblzma
|
||||
binary wouldn't actually be in the public domain in its entirety
|
||||
even though it contains no copyrighted code from the XZ Utils source
|
||||
package.
|
||||
|
||||
If you have questions, don't hesitate to ask the author(s) for more
|
||||
information.

GNU GENERAL PUBLIC LICENSE
|
||||
Version 2, June 1991
|
||||
|
||||
Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
|
||||
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 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 Lesser 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.,
|
||||
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 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.

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 Lesser General
|
||||
Public License instead of this License.

GNU GENERAL PUBLIC LICENSE
|
||||
Version 3, 29 June 2007
|
||||
|
||||
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
|
||||
Everyone is permitted to copy and distribute verbatim copies
|
||||
of this license document, but changing it is not allowed.
|
||||
|
||||
Preamble
|
||||
|
||||
The GNU General Public License is a free, copyleft license for
|
||||
software and other kinds of works.
|
||||
|
||||
The licenses for most software and other practical works are designed
|
||||
to take away your freedom to share and change the works. By contrast,
|
||||
the GNU General Public License is intended to guarantee your freedom to
|
||||
share and change all versions of a program--to make sure it remains free
|
||||
software for all its users. We, the Free Software Foundation, use the
|
||||
GNU General Public License for most of our software; it applies also to
|
||||
any other work released this way by its authors. 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
|
||||
them 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 prevent others from denying you
|
||||
these rights or asking you to surrender the rights. Therefore, you have
|
||||
certain responsibilities if you distribute copies of the software, or if
|
||||
you modify it: responsibilities to respect the freedom of others.
|
||||
|
||||
For example, if you distribute copies of such a program, whether
|
||||
gratis or for a fee, you must pass on to the recipients the same
|
||||
freedoms that you received. 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.
|
||||
|
||||
Developers that use the GNU GPL protect your rights with two steps:
|
||||
(1) assert copyright on the software, and (2) offer you this License
|
||||
giving you legal permission to copy, distribute and/or modify it.
|
||||
|
||||
For the developers' and authors' protection, the GPL clearly explains
|
||||
that there is no warranty for this free software. For both users' and
|
||||
authors' sake, the GPL requires that modified versions be marked as
|
||||
changed, so that their problems will not be attributed erroneously to
|
||||
authors of previous versions.
|
||||
|
||||
Some devices are designed to deny users access to install or run
|
||||
modified versions of the software inside them, although the manufacturer
|
||||
can do so. This is fundamentally incompatible with the aim of
|
||||
protecting users' freedom to change the software. The systematic
|
||||
pattern of such abuse occurs in the area of products for individuals to
|
||||
use, which is precisely where it is most unacceptable. Therefore, we
|
||||
have designed this version of the GPL to prohibit the practice for those
|
||||
products. If such problems arise substantially in other domains, we
|
||||
stand ready to extend this provision to those domains in future versions
|
||||
of the GPL, as needed to protect the freedom of users.
|
||||
|
||||
Finally, every program is threatened constantly by software patents.
|
||||
States should not allow patents to restrict development and use of
|
||||
software on general-purpose computers, but in those that do, we wish to
|
||||
avoid the special danger that patents applied to a free program could
|
||||
make it effectively proprietary. To prevent this, the GPL assures that
|
||||
patents cannot be used to render the program non-free.
|
||||
|
||||
The precise terms and conditions for copying, distribution and
|
||||
modification follow.
|
||||
|
||||
TERMS AND CONDITIONS
|
||||
|
||||
0. Definitions.
|
||||
|
||||
"This License" refers to version 3 of the GNU General Public License.
|
||||
|
||||
"Copyright" also means copyright-like laws that apply to other kinds of
|
||||
works, such as semiconductor masks.
|
||||
|
||||
"The Program" refers to any copyrightable work licensed under this
|
||||
License. Each licensee is addressed as "you". "Licensees" and
|
||||
"recipients" may be individuals or organizations.
|
||||
|
||||
To "modify" a work means to copy from or adapt all or part of the work
|
||||
in a fashion requiring copyright permission, other than the making of an
|
||||
exact copy. The resulting work is called a "modified version" of the
|
||||
earlier work or a work "based on" the earlier work.
|
||||
|
||||
A "covered work" means either the unmodified Program or a work based
|
||||
on the Program.
|
||||
|
||||
To "propagate" a work means to do anything with it that, without
|
||||
permission, would make you directly or secondarily liable for
|
||||
infringement under applicable copyright law, except executing it on a
|
||||
computer or modifying a private copy. Propagation includes copying,
|
||||
distribution (with or without modification), making available to the
|
||||
public, and in some countries other activities as well.
|
||||
|
||||
To "convey" a work means any kind of propagation that enables other
|
||||
parties to make or receive copies. Mere interaction with a user through
|
||||
a computer network, with no transfer of a copy, is not conveying.
|
||||
|
||||
An interactive user interface displays "Appropriate Legal Notices"
|
||||
to the extent that it includes a convenient and prominently visible
|
||||
feature that (1) displays an appropriate copyright notice, and (2)
|
||||
tells the user that there is no warranty for the work (except to the
|
||||
extent that warranties are provided), that licensees may convey the
|
||||
work under this License, and how to view a copy of this License. If
|
||||
the interface presents a list of user commands or options, such as a
|
||||
menu, a prominent item in the list meets this criterion.
|
||||
|
||||
1. Source Code.
|
||||
|
||||
The "source code" for a work means the preferred form of the work
|
||||
for making modifications to it. "Object code" means any non-source
|
||||
form of a work.
|
||||
|
||||
A "Standard Interface" means an interface that either is an official
|
||||
standard defined by a recognized standards body, or, in the case of
|
||||
interfaces specified for a particular programming language, one that
|
||||
is widely used among developers working in that language.
|
||||
|
||||
The "System Libraries" of an executable work include anything, other
|
||||
than the work as a whole, that (a) is included in the normal form of
|
||||
packaging a Major Component, but which is not part of that Major
|
||||
Component, and (b) serves only to enable use of the work with that
|
||||
Major Component, or to implement a Standard Interface for which an
|
||||
implementation is available to the public in source code form. A
|
||||
"Major Component", in this context, means a major essential component
|
||||
(kernel, window system, and so on) of the specific operating system
|
||||
(if any) on which the executable work runs, or a compiler used to
|
||||
produce the work, or an object code interpreter used to run it.
|
||||
|
||||
The "Corresponding Source" for a work in object code form means all
|
||||
the source code needed to generate, install, and (for an executable
|
||||
work) run the object code and to modify the work, including scripts to
|
||||
control those activities. However, it does not include the work's
|
||||
System Libraries, or general-purpose tools or generally available free
|
||||
programs which are used unmodified in performing those activities but
|
||||
which are not part of the work. For example, Corresponding Source
|
||||
includes interface definition files associated with source files for
|
||||
the work, and the source code for shared libraries and dynamically
|
||||
linked subprograms that the work is specifically designed to require,
|
||||
such as by intimate data communication or control flow between those
|
||||
subprograms and other parts of the work.
|
||||
|
||||
The Corresponding Source need not include anything that users
|
||||
can regenerate automatically from other parts of the Corresponding
|
||||
Source.
|
||||
|
||||
The Corresponding Source for a work in source code form is that
|
||||
same work.
|
||||
|
||||
2. Basic Permissions.
|
||||
|
||||
All rights granted under this License are granted for the term of
|
||||
copyright on the Program, and are irrevocable provided the stated
|
||||
conditions are met. This License explicitly affirms your unlimited
|
||||
permission to run the unmodified Program. The output from running a
|
||||
covered work is covered by this License only if the output, given its
|
||||
content, constitutes a covered work. This License acknowledges your
|
||||
rights of fair use or other equivalent, as provided by copyright law.
|
||||
|
||||
You may make, run and propagate covered works that you do not
|
||||
convey, without conditions so long as your license otherwise remains
|
||||
in force. You may convey covered works to others for the sole purpose
|
||||
of having them make modifications exclusively for you, or provide you
|
||||
with facilities for running those works, provided that you comply with
|
||||
the terms of this License in conveying all material for which you do
|
||||
not control copyright. Those thus making or running the covered works
|
||||
for you must do so exclusively on your behalf, under your direction
|
||||
and control, on terms that prohibit them from making any copies of
|
||||
your copyrighted material outside their relationship with you.
|
||||
|
||||
Conveying under any other circumstances is permitted solely under
|
||||
the conditions stated below. Sublicensing is not allowed; section 10
|
||||
makes it unnecessary.
|
||||
|
||||
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
|
||||
|
||||
No covered work shall be deemed part of an effective technological
|
||||
measure under any applicable law fulfilling obligations under article
|
||||
11 of the WIPO copyright treaty adopted on 20 December 1996, or
|
||||
similar laws prohibiting or restricting circumvention of such
|
||||
measures.
|
||||
|
||||
When you convey a covered work, you waive any legal power to forbid
|
||||
circumvention of technological measures to the extent such circumvention
|
||||
is effected by exercising rights under this License with respect to
|
||||
the covered work, and you disclaim any intention to limit operation or
|
||||
modification of the work as a means of enforcing, against the work's
|
||||
users, your or third parties' legal rights to forbid circumvention of
|
||||
technological measures.
|
||||
|
||||
4. Conveying Verbatim Copies.
|
||||
|
||||
You may convey 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;
|
||||
keep intact all notices stating that this License and any
|
||||
non-permissive terms added in accord with section 7 apply to the code;
|
||||
keep intact all notices of the absence of any warranty; and give all
|
||||
recipients a copy of this License along with the Program.
|
||||
|
||||
You may charge any price or no price for each copy that you convey,
|
||||
and you may offer support or warranty protection for a fee.
|
||||
|
||||
5. Conveying Modified Source Versions.
|
||||
|
||||
You may convey a work based on the Program, or the modifications to
|
||||
produce it from the Program, in the form of source code under the
|
||||
terms of section 4, provided that you also meet all of these conditions:
|
||||
|
||||
a) The work must carry prominent notices stating that you modified
|
||||
it, and giving a relevant date.
|
||||
|
||||
b) The work must carry prominent notices stating that it is
|
||||
released under this License and any conditions added under section
|
||||
7. This requirement modifies the requirement in section 4 to
|
||||
"keep intact all notices".
|
||||
|
||||
c) You must license the entire work, as a whole, under this
|
||||
License to anyone who comes into possession of a copy. This
|
||||
License will therefore apply, along with any applicable section 7
|
||||
additional terms, to the whole of the work, and all its parts,
|
||||
regardless of how they are packaged. This License gives no
|
||||
permission to license the work in any other way, but it does not
|
||||
invalidate such permission if you have separately received it.
|
||||
|
||||
d) If the work has interactive user interfaces, each must display
|
||||
Appropriate Legal Notices; however, if the Program has interactive
|
||||
interfaces that do not display Appropriate Legal Notices, your
|
||||
work need not make them do so.
|
||||
|
||||
A compilation of a covered work with other separate and independent
|
||||
works, which are not by their nature extensions of the covered work,
|
||||
and which are not combined with it such as to form a larger program,
|
||||
in or on a volume of a storage or distribution medium, is called an
|
||||
"aggregate" if the compilation and its resulting copyright are not
|
||||
used to limit the access or legal rights of the compilation's users
|
||||
beyond what the individual works permit. Inclusion of a covered work
|
||||
in an aggregate does not cause this License to apply to the other
|
||||
parts of the aggregate.
|
||||
|
||||
6. Conveying Non-Source Forms.
|
||||
|
||||
You may convey a covered work in object code form under the terms
|
||||
of sections 4 and 5, provided that you also convey the
|
||||
machine-readable Corresponding Source under the terms of this License,
|
||||
in one of these ways:
|
||||
|
||||
a) Convey the object code in, or embodied in, a physical product
|
||||
(including a physical distribution medium), accompanied by the
|
||||
Corresponding Source fixed on a durable physical medium
|
||||
customarily used for software interchange.
|
||||
|
||||
b) Convey the object code in, or embodied in, a physical product
|
||||
(including a physical distribution medium), accompanied by a
|
||||
written offer, valid for at least three years and valid for as
|
||||
long as you offer spare parts or customer support for that product
|
||||
model, to give anyone who possesses the object code either (1) a
|
||||
copy of the Corresponding Source for all the software in the
|
||||
product that is covered by this License, on a durable physical
|
||||
medium customarily used for software interchange, for a price no
|
||||
more than your reasonable cost of physically performing this
|
||||
conveying of source, or (2) access to copy the
|
||||
Corresponding Source from a network server at no charge.
|
||||
|
||||
c) Convey individual copies of the object code with a copy of the
|
||||
written offer to provide the Corresponding Source. This
|
||||
alternative is allowed only occasionally and noncommercially, and
|
||||
only if you received the object code with such an offer, in accord
|
||||
with subsection 6b.
|
||||
|
||||
d) Convey the object code by offering access from a designated
|
||||
place (gratis or for a charge), and offer equivalent access to the
|
||||
Corresponding Source in the same way through the same place at no
|
||||
further charge. You need not require recipients to copy the
|
||||
Corresponding Source along with the object code. If the place to
|
||||
copy the object code is a network server, the Corresponding Source
|
||||
may be on a different server (operated by you or a third party)
|
||||
that supports equivalent copying facilities, provided you maintain
|
||||
clear directions next to the object code saying where to find the
|
||||
Corresponding Source. Regardless of what server hosts the
|
||||
Corresponding Source, you remain obligated to ensure that it is
|
||||
available for as long as needed to satisfy these requirements.
|
||||
|
||||
e) Convey the object code using peer-to-peer transmission, provided
|
||||
you inform other peers where the object code and Corresponding
|
||||
Source of the work are being offered to the general public at no
|
||||
charge under subsection 6d.
|
||||
|
||||
A separable portion of the object code, whose source code is excluded
|
||||
from the Corresponding Source as a System Library, need not be
|
||||
included in conveying the object code work.
|
||||
|
||||
A "User Product" is either (1) a "consumer product", which means any
|
||||
tangible personal property which is normally used for personal, family,
|
||||
or household purposes, or (2) anything designed or sold for incorporation
|
||||
into a dwelling. In determining whether a product is a consumer product,
|
||||
doubtful cases shall be resolved in favor of coverage. For a particular
|
||||
product received by a particular user, "normally used" refers to a
|
||||
typical or common use of that class of product, regardless of the status
|
||||
of the particular user or of the way in which the particular user
|
||||
actually uses, or expects or is expected to use, the product. A product
|
||||
is a consumer product regardless of whether the product has substantial
|
||||
commercial, industrial or non-consumer uses, unless such uses represent
|
||||
the only significant mode of use of the product.
|
||||
|
||||
"Installation Information" for a User Product means any methods,
|
||||
procedures, authorization keys, or other information required to install
|
||||
and execute modified versions of a covered work in that User Product from
|
||||
a modified version of its Corresponding Source. The information must
|
||||
suffice to ensure that the continued functioning of the modified object
|
||||
code is in no case prevented or interfered with solely because
|
||||
modification has been made.
|
||||
|
||||
If you convey an object code work under this section in, or with, or
|
||||
specifically for use in, a User Product, and the conveying occurs as
|
||||
part of a transaction in which the right of possession and use of the
|
||||
User Product is transferred to the recipient in perpetuity or for a
|
||||
fixed term (regardless of how the transaction is characterized), the
|
||||
Corresponding Source conveyed under this section must be accompanied
|
||||
by the Installation Information. But this requirement does not apply
|
||||
if neither you nor any third party retains the ability to install
|
||||
modified object code on the User Product (for example, the work has
|
||||
been installed in ROM).
|
||||
|
||||
The requirement to provide Installation Information does not include a
|
||||
requirement to continue to provide support service, warranty, or updates
|
||||
for a work that has been modified or installed by the recipient, or for
|
||||
the User Product in which it has been modified or installed. Access to a
|
||||
network may be denied when the modification itself materially and
|
||||
adversely affects the operation of the network or violates the rules and
|
||||
protocols for communication across the network.
|
||||
|
||||
Corresponding Source conveyed, and Installation Information provided,
|
||||
in accord with this section must be in a format that is publicly
|
||||
documented (and with an implementation available to the public in
|
||||
source code form), and must require no special password or key for
|
||||
unpacking, reading or copying.
|
||||
|
||||
7. Additional Terms.
|
||||
|
||||
"Additional permissions" are terms that supplement the terms of this
|
||||
License by making exceptions from one or more of its conditions.
|
||||
Additional permissions that are applicable to the entire Program shall
|
||||
be treated as though they were included in this License, to the extent
|
||||
that they are valid under applicable law. If additional permissions
|
||||
apply only to part of the Program, that part may be used separately
|
||||
under those permissions, but the entire Program remains governed by
|
||||
this License without regard to the additional permissions.
|
||||
|
||||
When you convey a copy of a covered work, you may at your option
|
||||
remove any additional permissions from that copy, or from any part of
|
||||
it. (Additional permissions may be written to require their own
|
||||
removal in certain cases when you modify the work.) You may place
|
||||
additional permissions on material, added by you to a covered work,
|
||||
for which you have or can give appropriate copyright permission.
|
||||
|
||||
Notwithstanding any other provision of this License, for material you
|
||||
add to a covered work, you may (if authorized by the copyright holders of
|
||||
that material) supplement the terms of this License with terms:
|
||||
|
||||
a) Disclaiming warranty or limiting liability differently from the
|
||||
terms of sections 15 and 16 of this License; or
|
||||
|
||||
b) Requiring preservation of specified reasonable legal notices or
|
||||
author attributions in that material or in the Appropriate Legal
|
||||
Notices displayed by works containing it; or
|
||||
|
||||
c) Prohibiting misrepresentation of the origin of that material, or
|
||||
requiring that modified versions of such material be marked in
|
||||
reasonable ways as different from the original version; or
|
||||
|
||||
d) Limiting the use for publicity purposes of names of licensors or
|
||||
authors of the material; or
|
||||
|
||||
e) Declining to grant rights under trademark law for use of some
|
||||
trade names, trademarks, or service marks; or
|
||||
|
||||
f) Requiring indemnification of licensors and authors of that
|
||||
material by anyone who conveys the material (or modified versions of
|
||||
it) with contractual assumptions of liability to the recipient, for
|
||||
any liability that these contractual assumptions directly impose on
|
||||
those licensors and authors.
|
||||
|
||||
All other non-permissive additional terms are considered "further
|
||||
restrictions" within the meaning of section 10. If the Program as you
|
||||
received it, or any part of it, contains a notice stating that it is
|
||||
governed by this License along with a term that is a further
|
||||
restriction, you may remove that term. If a license document contains
|
||||
a further restriction but permits relicensing or conveying under this
|
||||
License, you may add to a covered work material governed by the terms
|
||||
of that license document, provided that the further restriction does
|
||||
not survive such relicensing or conveying.
|
||||
|
||||
If you add terms to a covered work in accord with this section, you
|
||||
must place, in the relevant source files, a statement of the
|
||||
additional terms that apply to those files, or a notice indicating
|
||||
where to find the applicable terms.
|
||||
|
||||
Additional terms, permissive or non-permissive, may be stated in the
|
||||
form of a separately written license, or stated as exceptions;
|
||||
the above requirements apply either way.
|
||||
|
||||
8. Termination.
|
||||
|
||||
You may not propagate or modify a covered work except as expressly
|
||||
provided under this License. Any attempt otherwise to propagate or
|
||||
modify it is void, and will automatically terminate your rights under
|
||||
this License (including any patent licenses granted under the third
|
||||
paragraph of section 11).
|
||||
|
||||
However, if you cease all violation of this License, then your
|
||||
license from a particular copyright holder is reinstated (a)
|
||||
provisionally, unless and until the copyright holder explicitly and
|
||||
finally terminates your license, and (b) permanently, if the copyright
|
||||
holder fails to notify you of the violation by some reasonable means
|
||||
prior to 60 days after the cessation.
|
||||
|
||||
Moreover, your license from a particular copyright holder is
|
||||
reinstated permanently if the copyright holder notifies you of the
|
||||
violation by some reasonable means, this is the first time you have
|
||||
received notice of violation of this License (for any work) from that
|
||||
copyright holder, and you cure the violation prior to 30 days after
|
||||
your receipt of the notice.
|
||||
|
||||
Termination of your rights under this section does not terminate the
|
||||
licenses of parties who have received copies or rights from you under
|
||||
this License. If your rights have been terminated and not permanently
|
||||
reinstated, you do not qualify to receive new licenses for the same
|
||||
material under section 10.
|
||||
|
||||
9. Acceptance Not Required for Having Copies.
|
||||
|
||||
You are not required to accept this License in order to receive or
|
||||
run a copy of the Program. Ancillary propagation of a covered work
|
||||
occurring solely as a consequence of using peer-to-peer transmission
|
||||
to receive a copy likewise does not require acceptance. However,
|
||||
nothing other than this License grants you permission to propagate or
|
||||
modify any covered work. These actions infringe copyright if you do
|
||||
not accept this License. Therefore, by modifying or propagating a
|
||||
covered work, you indicate your acceptance of this License to do so.
|
||||
|
||||
10. Automatic Licensing of Downstream Recipients.
|
||||
|
||||
Each time you convey a covered work, the recipient automatically
|
||||
receives a license from the original licensors, to run, modify and
|
||||
propagate that work, subject to this License. You are not responsible
|
||||
for enforcing compliance by third parties with this License.
|
||||
|
||||
An "entity transaction" is a transaction transferring control of an
|
||||
organization, or substantially all assets of one, or subdividing an
|
||||
organization, or merging organizations. If propagation of a covered
|
||||
work results from an entity transaction, each party to that
|
||||
transaction who receives a copy of the work also receives whatever
|
||||
licenses to the work the party's predecessor in interest had or could
|
||||
give under the previous paragraph, plus a right to possession of the
|
||||
Corresponding Source of the work from the predecessor in interest, if
|
||||
the predecessor has it or can get it with reasonable efforts.
|
||||
|
||||
You may not impose any further restrictions on the exercise of the
|
||||
rights granted or affirmed under this License. For example, you may
|
||||
not impose a license fee, royalty, or other charge for exercise of
|
||||
rights granted under this License, and you may not initiate litigation
|
||||
(including a cross-claim or counterclaim in a lawsuit) alleging that
|
||||
any patent claim is infringed by making, using, selling, offering for
|
||||
sale, or importing the Program or any portion of it.
|
||||
|
||||
11. Patents.
|
||||
|
||||
A "contributor" is a copyright holder who authorizes use under this
|
||||
License of the Program or a work on which the Program is based. The
|
||||
work thus licensed is called the contributor's "contributor version".
|
||||
|
||||
A contributor's "essential patent claims" are all patent claims
|
||||
owned or controlled by the contributor, whether already acquired or
|
||||
hereafter acquired, that would be infringed by some manner, permitted
|
||||
by this License, of making, using, or selling its contributor version,
|
||||
but do not include claims that would be infringed only as a
|
||||
consequence of further modification of the contributor version. For
|
||||
purposes of this definition, "control" includes the right to grant
|
||||
patent sublicenses in a manner consistent with the requirements of
|
||||
this License.
|
||||
|
||||
Each contributor grants you a non-exclusive, worldwide, royalty-free
|
||||
patent license under the contributor's essential patent claims, to
|
||||
make, use, sell, offer for sale, import and otherwise run, modify and
|
||||
propagate the contents of its contributor version.
|
||||
|
||||
In the following three paragraphs, a "patent license" is any express
|
||||
agreement or commitment, however denominated, not to enforce a patent
|
||||
(such as an express permission to practice a patent or covenant not to
|
||||
sue for patent infringement). To "grant" such a patent license to a
|
||||
party means to make such an agreement or commitment not to enforce a
|
||||
patent against the party.
|
||||
|
||||
If you convey a covered work, knowingly relying on a patent license,
|
||||
and the Corresponding Source of the work is not available for anyone
|
||||
to copy, free of charge and under the terms of this License, through a
|
||||
publicly available network server or other readily accessible means,
|
||||
then you must either (1) cause the Corresponding Source to be so
|
||||
available, or (2) arrange to deprive yourself of the benefit of the
|
||||
patent license for this particular work, or (3) arrange, in a manner
|
||||
consistent with the requirements of this License, to extend the patent
|
||||
license to downstream recipients. "Knowingly relying" means you have
|
||||
actual knowledge that, but for the patent license, your conveying the
|
||||
covered work in a country, or your recipient's use of the covered work
|
||||
in a country, would infringe one or more identifiable patents in that
|
||||
country that you have reason to believe are valid.
|
||||
|
||||
If, pursuant to or in connection with a single transaction or
|
||||
arrangement, you convey, or propagate by procuring conveyance of, a
|
||||
covered work, and grant a patent license to some of the parties
|
||||
receiving the covered work authorizing them to use, propagate, modify
|
||||
or convey a specific copy of the covered work, then the patent license
|
||||
you grant is automatically extended to all recipients of the covered
|
||||
work and works based on it.
|
||||
|
||||
A patent license is "discriminatory" if it does not include within
|
||||
the scope of its coverage, prohibits the exercise of, or is
|
||||
conditioned on the non-exercise of one or more of the rights that are
|
||||
specifically granted under this License. You may not convey a covered
|
||||
work if you are a party to an arrangement with a third party that is
|
||||
in the business of distributing software, under which you make payment
|
||||
to the third party based on the extent of your activity of conveying
|
||||
the work, and under which the third party grants, to any of the
|
||||
parties who would receive the covered work from you, a discriminatory
|
||||
patent license (a) in connection with copies of the covered work
|
||||
conveyed by you (or copies made from those copies), or (b) primarily
|
||||
for and in connection with specific products or compilations that
|
||||
contain the covered work, unless you entered into that arrangement,
|
||||
or that patent license was granted, prior to 28 March 2007.
|
||||
|
||||
Nothing in this License shall be construed as excluding or limiting
|
||||
any implied license or other defenses to infringement that may
|
||||
otherwise be available to you under applicable patent law.
|
||||
|
||||
12. No Surrender of Others' Freedom.
|
||||
|
||||
If 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 convey a
|
||||
covered work so as to satisfy simultaneously your obligations under this
|
||||
License and any other pertinent obligations, then as a consequence you may
|
||||
not convey it at all. For example, if you agree to terms that obligate you
|
||||
to collect a royalty for further conveying from those to whom you convey
|
||||
the Program, the only way you could satisfy both those terms and this
|
||||
License would be to refrain entirely from conveying the Program.
|
||||
|
||||
13. Use with the GNU Affero General Public License.
|
||||
|
||||
Notwithstanding any other provision of this License, you have
|
||||
permission to link or combine any covered work with a work licensed
|
||||
under version 3 of the GNU Affero General Public License into a single
|
||||
combined work, and to convey the resulting work. The terms of this
|
||||
License will continue to apply to the part which is the covered work,
|
||||
but the special requirements of the GNU Affero General Public License,
|
||||
section 13, concerning interaction through a network will apply to the
|
||||
combination as such.
|
||||
|
||||
14. Revised Versions of this License.
|
||||
|
||||
The Free Software Foundation may publish revised and/or new versions of
|
||||
the GNU 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 that a certain numbered version of the GNU General
|
||||
Public License "or any later version" applies to it, you have the
|
||||
option of following the terms and conditions either of that numbered
|
||||
version or of any later version published by the Free Software
|
||||
Foundation. If the Program does not specify a version number of the
|
||||
GNU General Public License, you may choose any version ever published
|
||||
by the Free Software Foundation.
|
||||
|
||||
If the Program specifies that a proxy can decide which future
|
||||
versions of the GNU General Public License can be used, that proxy's
|
||||
public statement of acceptance of a version permanently authorizes you
|
||||
to choose that version for the Program.
|
||||
|
||||
Later license versions may give you additional or different
|
||||
permissions. However, no additional obligations are imposed on any
|
||||
author or copyright holder as a result of your choosing to follow a
|
||||
later version.
|
||||
|
||||
15. Disclaimer of Warranty.
|
||||
|
||||
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.
|
||||
|
||||
16. Limitation of Liability.
|
||||
|
||||
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
||||
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
|
||||
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.
|
||||
|
||||
17. Interpretation of Sections 15 and 16.
|
||||
|
||||
If the disclaimer of warranty and limitation of liability provided
|
||||
above cannot be given local legal effect according to their terms,
|
||||
reviewing courts shall apply local law that most closely approximates
|
||||
an absolute waiver of all civil liability in connection with the
|
||||
Program, unless a warranty or assumption of liability accompanies a
|
||||
copy of the Program in return for a fee.
|
||||
|
||||
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
|
||||
state 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 3 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, see <http://www.gnu.org/licenses/>.
|
||||
|
||||
Also add information on how to contact you by electronic and paper mail.
|
||||
|
||||
If the program does terminal interaction, make it output a short
|
||||
notice like this when it starts in an interactive mode:
|
||||
|
||||
<program> Copyright (C) <year> <name of author>
|
||||
This program 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, your program's commands
|
||||
might be different; for a GUI interface, you would use an "about box".
|
||||
|
||||
You should also get your employer (if you work as a programmer) or school,
|
||||
if any, to sign a "copyright disclaimer" for the program, if necessary.
|
||||
For more information on this, and how to apply and follow the GNU GPL, see
|
||||
<http://www.gnu.org/licenses/>.
|
||||
|
||||
The GNU 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 Lesser General
|
||||
Public License instead of this License. But first, please read
|
||||

GNU LESSER GENERAL PUBLIC LICENSE
|

Version 2.1, February 1999
|
||||
|
||||
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
|
||||
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
|
||||
Everyone is permitted to copy and distribute verbatim copies
|
||||
of this license document, but changing it is not allowed.
|
||||
|
||||
[This is the first released version of the Lesser GPL. It also counts
|
||||
as the successor of the GNU Library Public License, version 2, hence
|
||||
the version number 2.1.]
|
||||
|
||||
Preamble
|
||||
|
||||
The licenses for most software are designed to take away your
|
||||
freedom to share and change it. By contrast, the GNU General Public
|
||||
Licenses are intended to guarantee your freedom to share and change
|
||||
free software--to make sure the software is free for all its users.
|
||||
|
||||
This license, the Lesser General Public License, applies to some
|
||||
specially designated software packages--typically libraries--of the
|
||||
Free Software Foundation and other authors who decide to use it. You
|
||||
can use it too, but we suggest you first think carefully about whether
|
||||
this license or the ordinary General Public License is the better
|
||||
strategy to use in any particular case, based on the explanations below.
|
||||
|
||||
When we speak of free software, we are referring to freedom of use,
|
||||
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 and use pieces of
|
||||
it in new free programs; and that you are informed that you can do
|
||||
these things.
|
||||
|
||||
To protect your rights, we need to make restrictions that forbid
|
||||
distributors to deny you these rights or to ask you to surrender these
|
||||
rights. These restrictions translate to certain responsibilities for
|
||||
you if you distribute copies of the library or if you modify it.
|
||||
|
||||
For example, if you distribute copies of the library, whether gratis
|
||||
or for a fee, you must give the recipients all the rights that we gave
|
||||
you. You must make sure that they, too, receive or can get the source
|
||||
code. If you link other code with the library, you must provide
|
||||
complete object files to the recipients, so that they can relink them
|
||||
with the library after making changes to the library and recompiling
|
||||
it. And you must show them these terms so they know their rights.
|
||||
|
||||
We protect your rights with a two-step method: (1) we copyright the
|
||||
library, and (2) we offer you this license, which gives you legal
|
||||
permission to copy, distribute and/or modify the library.
|
||||
|
||||
To protect each distributor, we want to make it very clear that
|
||||
there is no warranty for the free library. Also, if the library is
|
||||
modified by someone else and passed on, the recipients should know
|
||||
that what they have is not the original version, so that the original
|
||||
author's reputation will not be affected by problems that might be
|
||||
introduced by others.
|
||||
|
||||
Finally, software patents pose a constant threat to the existence of
|
||||
any free program. We wish to make sure that a company cannot
|
||||
effectively restrict the users of a free program by obtaining a
|
||||
restrictive license from a patent holder. Therefore, we insist that
|
||||
any patent license obtained for a version of the library must be
|
||||
consistent with the full freedom of use specified in this license.
|
||||
|
||||
Most GNU software, including some libraries, is covered by the
|
||||
ordinary GNU General Public License. This license, the GNU Lesser
|
||||
General Public License, applies to certain designated libraries, and
|
||||
is quite different from the ordinary General Public License. We use
|
||||
this license for certain libraries in order to permit linking those
|
||||
libraries into non-free programs.
|
||||
|
||||
When a program is linked with a library, whether statically or using
|
||||
a shared library, the combination of the two is legally speaking a
|
||||
combined work, a derivative of the original library. The ordinary
|
||||
General Public License therefore permits such linking only if the
|
||||
entire combination fits its criteria of freedom. The Lesser General
|
||||
Public License permits more lax criteria for linking other code with
|
||||
the library.
|
||||
|
||||
We call this license the "Lesser" General Public License because it
|
||||
does Less to protect the user's freedom than the ordinary General
|
||||
Public License. It also provides other free software developers Less
|
||||
of an advantage over competing non-free programs. These disadvantages
|
||||
are the reason we use the ordinary General Public License for many
|
||||
libraries. However, the Lesser license provides advantages in certain
|
||||
special circumstances.
|
||||
|
||||
For example, on rare occasions, there may be a special need to
|
||||
encourage the widest possible use of a certain library, so that it becomes
|
||||
a de-facto standard. To achieve this, non-free programs must be
|
||||
allowed to use the library. A more frequent case is that a free
|
||||
library does the same job as widely used non-free libraries. In this
|
||||
case, there is little to gain by limiting the free library to free
|
||||
software only, so we use the Lesser General Public License.
|
||||
|
||||
In other cases, permission to use a particular library in non-free
|
||||
programs enables a greater number of people to use a large body of
|
||||
free software. For example, permission to use the GNU C Library in
|
||||
non-free programs enables many more people to use the whole GNU
|
||||
operating system, as well as its variant, the GNU/Linux operating
|
||||
system.
|
||||
|
||||
Although the Lesser General Public License is Less protective of the
|
||||
users' freedom, it does ensure that the user of a program that is
|
||||
linked with the Library has the freedom and the wherewithal to run
|
||||
that program using a modified version of the Library.
|
||||
|
||||
The precise terms and conditions for copying, distribution and
|
||||
modification follow. Pay close attention to the difference between a
|
||||
"work based on the library" and a "work that uses the library". The
|
||||
former contains code derived from the library, whereas the latter must
|
||||
be combined with the library in order to run.
|
||||
|
||||
GNU LESSER GENERAL PUBLIC LICENSE
|
||||
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
||||
|
||||
0. This License Agreement applies to any software library or other
|
||||
program which contains a notice placed by the copyright holder or
|
||||
other authorized party saying it may be distributed under the terms of
|
||||
this Lesser General Public License (also called "this License").
|
||||
Each licensee is addressed as "you".
|
||||
|
||||
A "library" means a collection of software functions and/or data
|
||||
prepared so as to be conveniently linked with application programs
|
||||
(which use some of those functions and data) to form executables.
|
||||
|
||||
The "Library", below, refers to any such software library or work
|
||||
which has been distributed under these terms. A "work based on the
|
||||
Library" means either the Library or any derivative work under
|
||||
copyright law: that is to say, a work containing the Library or a
|
||||
portion of it, either verbatim or with modifications and/or translated
|
||||
straightforwardly into another language. (Hereinafter, translation is
|
||||
included without limitation in the term "modification".)
|
||||
|
||||
"Source code" for a work means the preferred form of the work for
|
||||
making modifications to it. For a library, 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 library.
|
||||
|
||||
Activities other than copying, distribution and modification are not
|
||||
covered by this License; they are outside its scope. The act of
|
||||
running a program using the Library is not restricted, and output from
|
||||
such a program is covered only if its contents constitute a work based
|
||||
on the Library (independent of the use of the Library in a tool for
|
||||
writing it). Whether that is true depends on what the Library does
|
||||
and what the program that uses the Library does.
|
||||
|
||||
1. You may copy and distribute verbatim copies of the Library's
|
||||
complete 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 distribute a copy of this License along with the
|
||||
Library.
|
||||
|
||||
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 Library or any portion
|
||||
of it, thus forming a work based on the Library, 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) The modified work must itself be a software library.
|
||||
|
||||
b) You must cause the files modified to carry prominent notices
|
||||
stating that you changed the files and the date of any change.
|
||||
|
||||
c) You must cause the whole of the work to be licensed at no
|
||||
charge to all third parties under the terms of this License.
|
||||
|
||||
d) If a facility in the modified Library refers to a function or a
|
||||
table of data to be supplied by an application program that uses
|
||||
the facility, other than as an argument passed when the facility
|
||||
is invoked, then you must make a good faith effort to ensure that,
|
||||
in the event an application does not supply such function or
|
||||
table, the facility still operates, and performs whatever part of
|
||||
its purpose remains meaningful.
|
||||
|
||||
(For example, a function in a library to compute square roots has
|
||||
a purpose that is entirely well-defined independent of the
|
||||
application. Therefore, Subsection 2d requires that any
|
||||
application-supplied function or table used by this function must
|
||||
be optional: if the application does not supply it, the square
|
||||
root function must still compute square roots.)
|
||||
|
||||
These requirements apply to the modified work as a whole. If
|
||||
identifiable sections of that work are not derived from the Library,
|
||||
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 Library, 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 Library.
|
||||
|
||||
In addition, mere aggregation of another work not based on the Library
|
||||
with the Library (or with a work based on the Library) on a volume of
|
||||
a storage or distribution medium does not bring the other work under
|
||||
the scope of this License.
|
||||
|
||||
3. You may opt to apply the terms of the ordinary GNU General Public
|
||||
License instead of this License to a given copy of the Library. To do
|
||||
this, you must alter all the notices that refer to this License, so
|
||||
that they refer to the ordinary GNU General Public License, version 2,
|
||||
instead of to this License. (If a newer version than version 2 of the
|
||||
ordinary GNU General Public License has appeared, then you can specify
|
||||
that version instead if you wish.) Do not make any other change in
|
||||
these notices.
|
||||
|
||||
Once this change is made in a given copy, it is irreversible for
|
||||
that copy, so the ordinary GNU General Public License applies to all
|
||||
subsequent copies and derivative works made from that copy.
|
||||
|
||||
This option is useful when you wish to copy part of the code of
|
||||
the Library into a program that is not a library.
|
||||
|
||||
4. You may copy and distribute the Library (or a portion or
|
||||
derivative of it, under Section 2) in object code or executable form
|
||||
under the terms of Sections 1 and 2 above provided that you 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.
|
||||
|
||||
If distribution of 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 satisfies the requirement to
|
||||
distribute the source code, even though third parties are not
|
||||
compelled to copy the source along with the object code.
|
||||
|
||||
5. A program that contains no derivative of any portion of the
|
||||
Library, but is designed to work with the Library by being compiled or
|
||||
linked with it, is called a "work that uses the Library". Such a
|
||||
work, in isolation, is not a derivative work of the Library, and
|
||||
therefore falls outside the scope of this License.
|
||||
|
||||
However, linking a "work that uses the Library" with the Library
|
||||
creates an executable that is a derivative of the Library (because it
|
||||
contains portions of the Library), rather than a "work that uses the
|
||||
library". The executable is therefore covered by this License.
|
||||
Section 6 states terms for distribution of such executables.
|
||||
|
||||
When a "work that uses the Library" uses material from a header file
|
||||
that is part of the Library, the object code for the work may be a
|
||||
derivative work of the Library even though the source code is not.
|
||||
Whether this is true is especially significant if the work can be
|
||||
linked without the Library, or if the work is itself a library. The
|
||||
threshold for this to be true is not precisely defined by law.
|
||||
|
||||
If such an object file uses only numerical parameters, data
|
||||
structure layouts and accessors, and small macros and small inline
|
||||
functions (ten lines or less in length), then the use of the object
|
||||
file is unrestricted, regardless of whether it is legally a derivative
|
||||
work. (Executables containing this object code plus portions of the
|
||||
Library will still fall under Section 6.)
|
||||
|
||||
Otherwise, if the work is a derivative of the Library, you may
|
||||
distribute the object code for the work under the terms of Section 6.
|
||||
Any executables containing that work also fall under Section 6,
|
||||
whether or not they are linked directly with the Library itself.
|
||||
|
||||
6. As an exception to the Sections above, you may also combine or
|
||||
link a "work that uses the Library" with the Library to produce a
|
||||
work containing portions of the Library, and distribute that work
|
||||
under terms of your choice, provided that the terms permit
|
||||
modification of the work for the customer's own use and reverse
|
||||
engineering for debugging such modifications.
|
||||
|
||||
You must give prominent notice with each copy of the work that the
|
||||
Library is used in it and that the Library and its use are covered by
|
||||
this License. You must supply a copy of this License. If the work
|
||||
during execution displays copyright notices, you must include the
|
||||
copyright notice for the Library among them, as well as a reference
|
||||
directing the user to the copy of this License. Also, you must do one
|
||||
of these things:
|
||||
|
||||
a) Accompany the work with the complete corresponding
|
||||
machine-readable source code for the Library including whatever
|
||||
changes were used in the work (which must be distributed under
|
||||
Sections 1 and 2 above); and, if the work is an executable linked
|
||||
with the Library, with the complete machine-readable "work that
|
||||
uses the Library", as object code and/or source code, so that the
|
||||
user can modify the Library and then relink to produce a modified
|
||||
executable containing the modified Library. (It is understood
|
||||
that the user who changes the contents of definitions files in the
|
||||
Library will not necessarily be able to recompile the application
|
||||
to use the modified definitions.)
|
||||
|
||||
b) Use a suitable shared library mechanism for linking with the
|
||||
Library. A suitable mechanism is one that (1) uses at run time a
|
||||
copy of the library already present on the user's computer system,
|
||||
rather than copying library functions into the executable, and (2)
|
||||
will operate properly with a modified version of the library, if
|
||||
the user installs one, as long as the modified version is
|
||||
interface-compatible with the version that the work was made with.
|
||||
|
||||
c) Accompany the work with a written offer, valid for at
|
||||
least three years, to give the same user the materials
|
||||
specified in Subsection 6a, above, for a charge no more
|
||||
than the cost of performing this distribution.
|
||||
|
||||
d) If distribution of the work is made by offering access to copy
|
||||
from a designated place, offer equivalent access to copy the above
|
||||
specified materials from the same place.
|
||||
|
||||
e) Verify that the user has already received a copy of these
|
||||
materials or that you have already sent this user a copy.
|
||||
|
||||
For an executable, the required form of the "work that uses the
|
||||
Library" must include any data and utility programs needed for
|
||||
reproducing the executable from it. However, as a special exception,
|
||||
the materials to be 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.
|
||||
|
||||
It may happen that this requirement contradicts the license
|
||||
restrictions of other proprietary libraries that do not normally
|
||||
accompany the operating system. Such a contradiction means you cannot
|
||||
use both them and the Library together in an executable that you
|
||||
distribute.
|
||||
|
||||
7. You may place library facilities that are a work based on the
|
||||
Library side-by-side in a single library together with other library
|
||||
facilities not covered by this License, and distribute such a combined
|
||||
library, provided that the separate distribution of the work based on
|
||||
the Library and of the other library facilities is otherwise
|
||||
permitted, and provided that you do these two things:
|
||||
|
||||
a) Accompany the combined library with a copy of the same work
|
||||
based on the Library, uncombined with any other library
|
||||
facilities. This must be distributed under the terms of the
|
||||
Sections above.
|
||||
|
||||
b) Give prominent notice with the combined library of the fact
|
||||
that part of it is a work based on the Library, and explaining
|
||||
where to find the accompanying uncombined form of the same work.
|
||||
|
||||
8. You may not copy, modify, sublicense, link with, or distribute
|
||||
the Library except as expressly provided under this License. Any
|
||||
attempt otherwise to copy, modify, sublicense, link with, or
|
||||
distribute the Library 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.
|
||||
|
||||
9. 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 Library or its derivative works. These actions are
|
||||
prohibited by law if you do not accept this License. Therefore, by
|
||||
modifying or distributing the Library (or any work based on the
|
||||
Library), you indicate your acceptance of this License to do so, and
|
||||
all its terms and conditions for copying, distributing or modifying
|
||||
the Library or works based on it.
|
||||
|
||||
10. Each time you redistribute the Library (or any work based on the
|
||||
Library), the recipient automatically receives a license from the
|
||||
original licensor to copy, distribute, link with or modify the Library
|
||||
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 with
|
||||
this License.
|
||||
|
||||
11. 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 Library at all. For example, if a patent
|
||||
license would not permit royalty-free redistribution of the Library 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 Library.
|
||||
|
||||
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.
|
||||
|
||||
12. If the distribution and/or use of the Library is restricted in
|
||||
certain countries either by patents or by copyrighted interfaces, the
|
||||
original copyright holder who places the Library 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.
|
||||
|
||||
13. The Free Software Foundation may publish revised and/or new
|
||||
versions of the Lesser 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 Library
|
||||
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 Library does not specify a
|
||||
license version number, you may choose any version ever published by
|
||||
the Free Software Foundation.
|
||||
|
||||
14. If you wish to incorporate parts of the Library into other free
|
||||
programs whose distribution conditions are incompatible with these,
|
||||
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
|
||||
|
||||
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
|
||||
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
|
||||
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
|
||||
OTHER PARTIES PROVIDE THE LIBRARY "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
|
||||
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
|
||||
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
|
||||
|
||||
16. 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 LIBRARY 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
|
||||
LIBRARY (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 LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), 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 Libraries
|
||||
|
||||
If you develop a new library, and you want it to be of the greatest
|
||||
possible use to the public, we recommend making it free software that
|
||||
everyone can redistribute and change. You can do so by permitting
|
||||
redistribution under these terms (or, alternatively, under the terms of the
|
||||
ordinary General Public License).
|
||||
|
||||
To apply these terms, attach the following notices to the library. 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 library's name and a brief idea of what it does.>
|
||||
Copyright (C) <year> <name of author>
|
||||
|
||||
This library is free software; you can redistribute it and/or
|
||||
modify it under the terms of the GNU Lesser General Public
|
||||
License as published by the Free Software Foundation; either
|
||||
version 2.1 of the License, or (at your option) any later version.
|
||||
|
||||
This library 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
|
||||
Lesser General Public License for more details.
|
||||
|
||||
You should have received a copy of the GNU Lesser General Public
|
||||
License along with this library; if not, write to the Free Software
|
||||
Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
|
||||
|
||||
Also add information on how to contact you by electronic and paper mail.
|
||||
|
||||
You should also get your employer (if you work as a programmer) or your
|
||||
school, if any, to sign a "copyright disclaimer" for the library, if
|
||||
necessary. Here is a sample; alter the names:
|
||||
|
||||
Yoyodyne, Inc., hereby disclaims all copyright interest in the
|
||||
library `Frob' (a library for tweaking knobs) written by James Random Hacker.
|
||||

0. Preface
|
||||
----------
|
||||
|
||||
If you aren't familiar with building packages that use GNU Autotools,
|
||||
see the file INSTALL.generic for generic instructions before reading
|
||||
further.
|
||||
|
||||
If you are going to build a package for distribution, see also the
|
||||
file PACKAGERS. It contains information that should help making the
|
||||
binary packages as good as possible, but the information isn't very
|
||||
interesting to those making local builds for private use or for use
|
||||
in special situations like embedded systems.
|
||||
|
||||
|
||||
1. Supported platforms
|
||||
----------------------
|
||||
|
||||
XZ Utils are developed on GNU/Linux, but they should work on many
|
||||
POSIX-like operating systems like *BSDs and Solaris, and even on
|
||||
a few non-POSIX operating systems.
|
||||
|
||||
|
||||
1.1. Compilers
|
||||
|
||||
A C99 compiler is required to compile XZ Utils. If you use GCC, you
|
||||
need at least version 3.x.x. GCC version 2.xx.x doesn't support some
|
||||
C99 features used in XZ Utils source code, thus GCC 2 won't compile
|
||||
XZ Utils.
|
||||
|
||||
XZ Utils takes advantage of some GNU C extensions when building
|
||||
with GCC. Because these extensions are used only when building
|
||||
with GCC, it should be possible to use any C99 compiler.
|
||||
|
||||
|
||||
1.2. Platform-specific notes
|
||||
|
||||
1.2.1. AIX
|
||||
|
||||
If you use IBM XL C compiler, pass CC=xlc_r to configure. If
|
||||
you use CC=xlc instead, you must disable threading support
|
||||
with --disable-threads (usually not recommended).
|
||||
|
||||
|
||||
1.2.2. IRIX
|
||||
|
||||
MIPSpro 7.4.4m has been reported to produce broken code if using
|
||||
the -O2 optimization flag ("make check" fails). Using -O1 should
|
||||
work.
|
||||
|
||||
A problem has been reported when using shared liblzma. Passing
|
||||
--disable-shared to configure works around this. Alternatively,
|
||||
putting "-64" to CFLAGS to build a 64-bit version might help too.
|
||||
|
||||
|
||||
1.2.3. MINIX 3
|
||||
|
||||
The default install of MINIX 3 includes Amsterdam Compiler Kit (ACK),
|
||||
which doesn't support C99. Install GCC to compile XZ Utils.
|
||||
|
||||
MINIX 3.1.8 and older have bugs in /usr/include/stdint.h, which has
|
||||
to be patched before XZ Utils can be compiled correctly. See
|
||||
<http://gforge.cs.vu.nl/gf/project/minix/tracker/?action=TrackerItemEdit&tracker_item_id=537>.
|
||||
|
||||
MINIX 3.2.0 and later use a different libc and aren't affected by
|
||||
the above bug.
|
||||
|
||||
XZ Utils doesn't have code to detect the amount of physical RAM and
|
||||
number of CPU cores on MINIX 3.
|
||||
|
||||
See section 4.4 in this file about symbol visibility warnings (you
|
||||
may want to pass gl_cv_cc_visibility=no to configure).
|
||||
|
||||
|
||||
1.2.4. OpenVMS
|
||||
|
||||
XZ Utils can be built for OpenVMS, but the build system files
|
||||
are not included in the XZ Utils source package. The required
|
||||
OpenVMS-specific files are maintained by Jouk Jansen and can be
|
||||
downloaded here:
|
||||
|
||||
http://nchrem.tnw.tudelft.nl/openvms/software2.html#xzutils
|
||||
|
||||
|
||||
1.2.5. Solaris, OpenSolaris, and derivatives
|
||||
|
||||
The following linker error has been reported on some x86 systems:
|
||||
|
||||
ld: fatal: relocation error: R_386_GOTOFF: ...
|
||||
|
||||
This can be worked around by passing gl_cv_cc_visibility=no
|
||||
as an argument to the configure script.
|
||||
|
||||
test_scripts.sh in "make check" may fail if good enough tools are
|
||||
missing from PATH (/usr/xpg4/bin or /usr/xpg6/bin). See sections
|
||||
4.5 and 3.2 for more information.
|
||||
|
||||
|
||||
1.2.6. Tru64
|
||||
|
||||
If you try to use the native C compiler on Tru64 (passing CC=cc to
|
||||
configure), you may need the workaround mention in section 4.1 in
|
||||
this file (pass also ac_cv_prog_cc_c99= to configure).
|
||||
|
||||
|
||||
1.2.7. Windows
|
||||
|
||||
Building XZ Utils on Windows is supported under the following
|
||||
environments:
|
||||
|
||||
- MinGW-w64 + MSYS (32-bit and 64-bit x86): This is used
|
||||
for building the official binary packages for Windows.
|
||||
There is windows/build.bash to ease packaging XZ Utils with
|
||||
MinGW(-w64) + MSYS into a redistributable .zip or .7z file.
|
||||
See windows/INSTALL-MinGW.txt for more information.
|
||||
|
||||
- MinGW + MSYS (32-bit x86): I haven't recently tested this.
|
||||
|
||||
- Cygwin 1.7.35 and later: NOTE that using XZ Utils >= 5.2.0
|
||||
under Cygwin older than 1.7.35 can lead to DATA LOSS! If
|
||||
you must use an old Cygwin version, stick to XZ Utils 5.0.x
|
||||
which is safe under older Cygwin versions. You can check
|
||||
the Cygwin version with the command "cygcheck -V".
|
||||
|
||||
- Microsoft Visual Studio 2013 update 2 or later (MSVC for short):
|
||||
See windows/INSTALL-MSVC.txt for more information.
|
||||
|
||||
It may be possible to build liblzma with other toolchains too, but
|
||||
that will probably require writing a separate makefile. Building
|
||||
the command line tools with non-GNU toolchains will be harder than
|
||||
building only liblzma.
|
||||
|
||||
Even if liblzma is built with MinGW(-w64), the resulting DLL can
|
||||
be used by other compilers and linkers, including MSVC. See
|
||||
windows/README-Windows.txt for details.
|
||||
|
||||
|
||||
1.2.8. DOS
|
||||
|
||||
There is an experimental Makefile in the "dos" directory to build
|
||||
XZ Utils on DOS using DJGPP. Support for long file names (LFN) is
|
||||
needed. See dos/README for more information.
|
||||
|
||||
GNU Autotools based build hasn't been tried on DOS. If you try, I
|
||||
would like to hear if it worked.
|
||||
|
||||
|
||||
1.3. Adding support for new platforms
|
||||
|
||||
If you have written patches to make XZ Utils to work on previously
|
||||
unsupported platform, please send the patches to me! I will consider
|
||||
including them to the official version. It's nice to minimize the
|
||||
need of third-party patching.
|
||||
|
||||
One exception: Don't request or send patches to change the whole
|
||||
source package to C89. I find C99 substantially nicer to write and
|
||||
maintain. However, the public library headers must be in C89 to
|
||||
avoid frustrating those who maintain programs, which are strictly
|
||||
in C89 or C++.
|
||||
|
||||
|
||||
2. configure options
|
||||
--------------------
|
||||
|
||||
In most cases, the defaults are what you want. Many of the options
|
||||
below are useful only when building a size-optimized version of
|
||||
liblzma or command line tools.
|
||||
|
||||
--enable-encoders=LIST
|
||||
--disable-encoders
|
||||
Specify a comma-separated LIST of filter encoders to
|
||||
build. See "./configure --help" for exact list of
|
||||
available filter encoders. The default is to build all
|
||||
supported encoders.
|
||||
|
||||
If LIST is empty or --disable-encoders is used, no filter
|
||||
encoders will be built and also the code shared between
|
||||
encoders will be omitted.
|
||||
|
||||
Disabling encoders will remove some symbols from the
|
||||
liblzma ABI, so this option should be used only when it
|
||||
is known to not cause problems.
|
||||
|
||||
--enable-decoders=LIST
|
||||
--disable-decoders
|
||||
This is like --enable-encoders but for decoders. The
|
||||
default is to build all supported decoders.
|
||||
|
||||
--enable-match-finders=LIST
|
||||
liblzma includes two categories of match finders:
|
||||
hash chains and binary trees. Hash chains (hc3 and hc4)
|
||||
are quite fast but they don't provide the best compression
|
||||
ratio. Binary trees (bt2, bt3 and bt4) give excellent
|
||||
compression ratio, but they are slower and need more
|
||||
memory than hash chains.
|
||||
|
||||
You need to enable at least one match finder to build the
|
||||
LZMA1 or LZMA2 filter encoders. Usually hash chains are
|
||||
used only in the fast mode, while binary trees are used to
|
||||
when the best compression ratio is wanted.
|
||||
|
||||
The default is to build all the match finders if LZMA1
|
||||
or LZMA2 filter encoders are being built.
|
||||
|
||||
--enable-checks=LIST
|
||||
liblzma support multiple integrity checks. CRC32 is
|
||||
mandatory, and cannot be omitted. See "./configure --help"
|
||||
for exact list of available integrity check types.
|
||||
|
||||
liblzma and the command line tools can decompress files
|
||||
which use unsupported integrity check type, but naturally
|
||||
the file integrity cannot be verified in that case.
|
||||
|
||||
Disabling integrity checks may remove some symbols from
|
||||
the liblzma ABI, so this option should be used only when
|
||||
it is known to not cause problems.
|
||||
|
||||
--disable-xz
|
||||
--disable-xzdec
|
||||
--disable-lzmadec
|
||||
--disable-lzmainfo
|
||||
Don't build and install the command line tool mentioned
|
||||
in the option name.
|
||||
|
||||
NOTE: Disabling xz will skip some tests in "make check".
|
||||
|
||||
NOTE: If xzdec is disabled and lzmadec is left enabled,
|
||||
a dangling man page symlink lzmadec.1 -> xzdec.1 is
|
||||
created.
|
||||
|
||||
--disable-lzma-links
|
||||
Don't create symlinks for LZMA Utils compatibility.
|
||||
This includes lzma, unlzma, and lzcat. If scripts are
|
||||
installed, also lzdiff, lzcmp, lzgrep, lzegrep, lzfgrep,
|
||||
lzmore, and lzless will be omitted if this option is used.
|
||||
|
||||
--disable-scripts
|
||||
Don't install the scripts xzdiff, xzgrep, xzmore, xzless,
|
||||
and their symlinks.
|
||||
|
||||
--disable-doc
|
||||
Don't install the documentation files to $docdir
|
||||
(often /usr/doc/xz or /usr/local/doc/xz). Man pages
|
||||
will still be installed. The $docdir can be changed
|
||||
with --docdir=DIR.
|
||||
|
||||
--disable-assembler
|
||||
liblzma includes some assembler optimizations. Currently
|
||||
there is only assembler code for CRC32 and CRC64 for
|
||||
32-bit x86.
|
||||
|
||||
All the assembler code in liblzma is position-independent
|
||||
code, which is suitable for use in shared libraries and
|
||||
position-independent executables. So far only i386
|
||||
instructions are used, but the code is optimized for i686
|
||||
class CPUs. If you are compiling liblzma exclusively for
|
||||
pre-i686 systems, you may want to disable the assembler
|
||||
code.
|
||||
|
||||
--enable-unaligned-access
|
||||
Allow liblzma to use unaligned memory access for 16-bit
|
||||
and 32-bit loads and stores. This should be enabled only
|
||||
when the hardware supports this, i.e. when unaligned
|
||||
access is fast. Some operating system kernels emulate
|
||||
unaligned access, which is extremely slow. This option
|
||||
shouldn't be used on systems that rely on such emulation.
|
||||
|
||||
Unaligned access is enabled by default on x86, x86-64,
|
||||
and big endian PowerPC.
|
||||
|
||||
--enable-small
|
||||
Reduce the size of liblzma by selecting smaller but
|
||||
semantically equivalent version of some functions, and
|
||||
omit precomputed lookup tables. This option tends to
|
||||
make liblzma slightly slower.
|
||||
|
||||
Note that while omitting the precomputed tables makes
|
||||
liblzma smaller on disk, the tables are still needed at
|
||||
run time, and need to be computed at startup. This also
|
||||
means that the RAM holding the tables won't be shared
|
||||
between applications linked against shared liblzma.
|
||||
|
||||
This option doesn't modify CFLAGS to tell the compiler
|
||||
to optimize for size. You need to add -Os or equivalent
|
||||
flag(s) to CFLAGS manually.
|
||||
|
||||
--enable-assume-ram=SIZE
|
||||
On the most common operating systems, XZ Utils is able to
|
||||
detect the amount of physical memory on the system. This
|
||||
information is used by the options --memlimit-compress,
|
||||
--memlimit-decompress, and --memlimit when setting the
|
||||
limit to a percentage of total RAM.
|
||||
|
||||
On some systems, there is no code to detect the amount of
|
||||
RAM though. Using --enable-assume-ram one can set how much
|
||||
memory to assume on these systems. SIZE is given as MiB.
|
||||
The default is 128 MiB.
|
||||
|
||||
Feel free to send patches to add support for detecting
|
||||
the amount of RAM on the operating system you use. See
|
||||
src/common/tuklib_physmem.c for details.
|
||||
|
||||
--enable-threads=METHOD
|
||||
Threading support is enabled by default so normally there
|
||||
is no need to specify this option.
|
||||
|
||||
Supported values for METHOD:
|
||||
|
||||
yes Autodetect the threading method. If none
|
||||
is found, configure will give an error.
|
||||
|
||||
posix Use POSIX pthreads. This is the default
|
||||
except on Windows outside Cygwin.
|
||||
|
||||
win95 Use Windows 95 compatible threads. This
|
||||
is compatible with Windows XP and later
|
||||
too. This is the default for 32-bit x86
|
||||
Windows builds. The `win95' threading is
|
||||
incompatible with --enable-small.
|
||||
|
||||
vista Use Windows Vista compatible threads. The
|
||||
resulting binaries won't run on Windows XP
|
||||
or older. This is the default for Windows
|
||||
excluding 32-bit x86 builds (that is, on
|
||||
x86-64 the default is `vista').
|
||||
|
||||
no Disable threading support. This is the
|
||||
same as using --disable-threads.
|
||||
NOTE: If combined with --enable-small, the
|
||||
resulting liblzma won't be thread safe,
|
||||
that is, if a multi-threaded application
|
||||
calls any liblzma functions from more than
|
||||
one thread, something bad may happen.
|
||||
|
||||
--enable-symbol-versions
|
||||
Use symbol versioning for liblzma. This is enabled by
|
||||
default on GNU/Linux, other GNU-based systems, and
|
||||
FreeBSD.
|
||||
|
||||
--enable-debug
|
||||
This enables the assert() macro and possibly some other
|
||||
run-time consistency checks. It makes the code slower, so
|
||||
you normally don't want to have this enabled.
|
||||
|
||||
--enable-werror
|
||||
If building with GCC, make all compiler warnings an error,
|
||||
that abort the compilation. This may help catching bugs,
|
||||
and should work on most systems. This has no effect on the
|
||||
resulting binaries.
|
||||
|
||||
|
||||
2.1. Static vs. dynamic linking of liblzma
|
||||
|
||||
On 32-bit x86, linking against static liblzma can give a minor
|
||||
speed improvement. Static libraries on x86 are usually compiled as
|
||||
position-dependent code (non-PIC) and shared libraries are built as
|
||||
position-independent code (PIC). PIC wastes one register, which can
|
||||
make the code slightly slower compared to a non-PIC version. (Note
|
||||
that this doesn't apply to x86-64.)
|
||||
|
||||
If you want to link xz against static liblzma, the simplest way
|
||||
is to pass --disable-shared to configure. If you want also shared
|
||||
liblzma, run configure again and run "make install" only for
|
||||
src/liblzma.
|
||||
|
||||
|
||||
2.2. Optimizing xzdec and lzmadec
|
||||
|
||||
xzdec and lzmadec are intended to be relatively small instead of
|
||||
optimizing for the best speed. Thus, it is a good idea to build
|
||||
xzdec and lzmadec separately:
|
||||
|
||||
- To link the tools against static liblzma, pass --disable-shared
|
||||
to configure.
|
||||
|
||||
- To select somewhat size-optimized variant of some things in
|
||||
liblzma, pass --enable-small to configure.
|
||||
|
||||
- Tell the compiler to optimize for size instead of speed.
|
||||
E.g. with GCC, put -Os into CFLAGS.
|
||||
|
||||
- xzdec and lzmadec will never use multithreading capabilities of
|
||||
liblzma. You can avoid dependency on libpthread by passing
|
||||
--disable-threads to configure.
|
||||
|
||||
- There are and will be no translated messages for xzdec and
|
||||
lzmadec, so it is fine to pass also --disable-nls to configure.
|
||||
|
||||
- Only decoder code is needed, so you can speed up the build
|
||||
slightly by passing --disable-encoders to configure. This
|
||||
shouldn't affect the final size of the executables though,
|
||||
because the linker is able to omit the encoder code anyway.
|
||||
|
||||
If you have no use for xzdec or lzmadec, you can disable them with
|
||||
--disable-xzdec and --disable-lzmadec.
|
||||
|
||||
|
||||
3. xzgrep and other scripts
|
||||
---------------------------
|
||||
|
||||
3.1. Dependencies
|
||||
|
||||
POSIX shell (sh) and bunch of other standard POSIX tools are required
|
||||
to run the scripts. The configure script tries to find a POSIX
|
||||
compliant sh, but if it fails, you can force the shell by passing
|
||||
gl_cv_posix_shell=/path/to/posix-sh as an argument to the configure
|
||||
script.
|
||||
|
||||
xzdiff (xzcmp/lzdiff/lzcmp) may use mktemp if it is available. As
|
||||
a fallback xzdiff will use mkdir to securely create a temporary
|
||||
directory. Having mktemp available is still recommended since the
|
||||
mkdir fallback method isn't as robust as mktemp is. The original
|
||||
mktemp can be found from <http://www.mktemp.org/>. On GNU, most will
|
||||
use the mktemp program from GNU coreutils instead of the original
|
||||
implementation. Both mktemp versions are fine.
|
||||
|
||||
In addition to using xz to decompress .xz files, xzgrep and xzdiff
|
||||
use gzip, bzip2, and lzop to support .gz, bz2, and .lzo files.
|
||||
|
||||
|
||||
3.2. PATH
|
||||
|
||||
The scripts assume that the required tools (standard POSIX utilities,
|
||||
mktemp, and xz) are in PATH; the scripts don't set the PATH themselves.
|
||||
Some people like this while some think this is a bug. Those in the
|
||||
latter group can easily patch the scripts before running the configure
|
||||
script by taking advantage of a placeholder line in the scripts.
|
||||
|
||||
For example, to make the scripts prefix /usr/bin:/bin to PATH:
|
||||
|
||||
perl -pi -e 's|^#SET_PATH.*$|PATH=/usr/bin:/bin:\$PATH|' \
|
||||
src/scripts/xz*.in
|
||||
|
||||
|
||||
4. Troubleshooting
|
||||
------------------
|
||||
|
||||
4.1. "No C99 compiler was found."
|
||||
|
||||
You need a C99 compiler to build XZ Utils. If the configure script
|
||||
cannot find a C99 compiler and you think you have such a compiler
|
||||
installed, set the compiler command by passing CC=/path/to/c99 as
|
||||
an argument to the configure script.
|
||||
|
||||
If you get this error even when you think your compiler supports C99,
|
||||
you can override the test by passing ac_cv_prog_cc_c99= as an argument
|
||||
to the configure script. The test for C99 compiler is not perfect (and
|
||||
it is not as easy to make it perfect as it sounds), so sometimes this
|
||||
may be needed. You will get a compile error if your compiler doesn't
|
||||
support enough C99.
|
||||
|
||||
|
||||
4.2. "No POSIX conforming shell (sh) was found."
|
||||
|
||||
xzgrep and other scripts need a shell that (roughly) conforms
|
||||
to POSIX. The configure script tries to find such a shell. If
|
||||
it fails, you can force the shell to be used by passing
|
||||
gl_cv_posix_shell=/path/to/posix-sh as an argument to the configure
|
||||
script. Alternatively you can omit the installation of scripts and
|
||||
this error by passing --disable-scripts to configure.
|
||||
|
||||
|
||||
4.3. configure works but build fails at crc32_x86.S
|
||||
|
||||
The easy fix is to pass --disable-assembler to the configure script.
|
||||
|
||||
The configure script determines if assembler code can be used by
|
||||
looking at the configure triplet; there is currently no check if
|
||||
the assembler code can actually actually be built. The x86 assembler
|
||||
code should work on x86 GNU/Linux, *BSDs, Solaris, Darwin, MinGW,
|
||||
Cygwin, and DJGPP. On other x86 systems, there may be problems and
|
||||
the assembler code may need to be disabled with the configure option.
|
||||
|
||||
If you get this error when building for x86-64, you have specified or
|
||||
the configure script has misguessed your architecture. Pass the
|
||||
correct configure triplet using the --build=CPU-COMPANY-SYSTEM option
|
||||
(see INSTALL.generic).
|
||||
|
||||
|
||||
4.4. Lots of warnings about symbol visibility
|
||||
|
||||
On some systems where symbol visibility isn't supported, GCC may
|
||||
still accept the visibility options and attributes, which will make
|
||||
configure think that visibility is supported. This will result in
|
||||
many compiler warnings. You can avoid the warnings by forcing the
|
||||
visibility support off by passing gl_cv_cc_visibility=no as an
|
||||
argument to the configure script. This has no effect on the
|
||||
resulting binaries, but fewer warnings looks nicer and may allow
|
||||
using --enable-werror.
|
||||
|
||||
|
||||
4.5. "make check" fails
|
||||
|
||||
If the other tests pass but test_scripts.sh fails, then the problem
|
||||
is in the scripts in src/scripts. Comparing the contents of
|
||||
tests/xzgrep_test_output to tests/xzgrep_expected_output might
|
||||
give a good idea about problems in xzgrep. One possibility is that
|
||||
some tools are missing from the current PATH or the tools lack
|
||||
support for some POSIX features. This can happen at least on
|
||||
Solaris where the tools in /bin may be ancient but good enough
|
||||
tools are available in /usr/xpg4/bin or /usr/xpg6/bin. One fix
|
||||
for this problem is described in section 3.2 of this file.
|
||||
|
||||
If tests other than test_scripts.sh fail, a likely reason is that
|
||||
libtool links the test programs against an installed version of
|
||||
liblzma instead of the version that was just built. This is
|
||||
obviously a bug which seems to happen on some platforms.
|
||||
A workaround is to uninstall the old liblzma versions first.
|
||||
|
||||
If the problem isn't any of those described above, then it's likely
|
||||
a bug in XZ Utils or in the compiler. See the platform-specific
|
||||
notes in this file for possible known problems. Please report
|
||||
a bug if you cannot solve the problem. See README for contact
|
||||
information.
|
||||
|
||||
|
||||
4.6. liblzma.so (or similar) not found when running xz
|
||||
|
||||
If you installed the package with "make install" and get an error
|
||||
about liblzma.so (or a similarly named file) being missing, try
|
||||
running "ldconfig" to update the run-time linker cache (if your
|
||||
operating system has such a command).

Basic Installation
|
||||
==================
|
||||
|
||||
Briefly, the shell commands `./configure; make; make install' should
|
||||
configure, build, and install this package. The following
|
||||
more-detailed instructions are generic; see the `README' file for
|
||||
instructions specific to this package. Some packages provide this
|
||||
`INSTALL' file but do not implement all of the features documented
|
||||
below. The lack of an optional feature in a given package is not
|
||||
necessarily a bug. More recommendations for GNU packages can be found
|
||||
in *note Makefile Conventions: (standards)Makefile Conventions.
|
||||
|
||||
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, and a
|
||||
file `config.log' containing compiler output (useful mainly for
|
||||
debugging `configure').
|
||||
|
||||
It can also use an optional file (typically called `config.cache'
|
||||
and enabled with `--cache-file=config.cache' or simply `-C') that saves
|
||||
the results of its tests to speed up reconfiguring. Caching is
|
||||
disabled by default to prevent problems with accidental use of stale
|
||||
cache files.
|
||||
|
||||
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 you are using the cache, and at
|
||||
some point `config.cache' contains results you don't want to keep, you
|
||||
may remove or edit it.
|
||||
|
||||
The file `configure.ac' (or `configure.in') is used to create
|
||||
`configure' by a program called `autoconf'. You need `configure.ac' 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.
|
||||
|
||||
Running `configure' might take a while. 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, generally using the just-built uninstalled binaries.
|
||||
|
||||
4. Type `make install' to install the programs and any data files and
|
||||
documentation. When installing into a prefix owned by root, it is
|
||||
recommended that the package be configured and built as a regular
|
||||
user, and only the `make install' phase executed with root
|
||||
privileges.
|
||||
|
||||
5. Optionally, type `make installcheck' to repeat any self-tests, but
|
||||
this time using the binaries in their final installed location.
|
||||
This target does not install anything. Running this target as a
|
||||
regular user, particularly if the prior `make install' required
|
||||
root privileges, verifies that the installation completed
|
||||
correctly.
|
||||
|
||||
6. 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.
|
||||
|
||||
7. Often, you can also type `make uninstall' to remove the installed
|
||||
files again. In practice, not all packages have tested that
|
||||
uninstallation works correctly, even though it is required by the
|
||||
GNU Coding Standards.
|
||||
|
||||
8. Some packages, particularly those that use Automake, provide `make
|
||||
distcheck', which can by used by developers to test that all other
|
||||
targets like `make install' and `make uninstall' work correctly.
|
||||
This target is generally not run by end users.
|
||||
|
||||
Compilers and Options
|
||||
=====================
|
||||
|
||||
Some systems require unusual options for compilation or linking that
|
||||
the `configure' script does not know about. Run `./configure --help'
|
||||
for details on some of the pertinent environment variables.
|
||||
|
||||
You can give `configure' initial values for configuration parameters
|
||||
by setting variables in the command line or in the environment. Here
|
||||
is an example:
|
||||
|
||||
./configure CC=c99 CFLAGS=-g LIBS=-lposix
|
||||
|
||||
*Note Defining Variables::, for more details.
|
||||
|
||||
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 can use 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 `..'. This
|
||||
is known as a "VPATH" build.
|
||||
|
||||
With a non-GNU `make', it is safer 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.
|
||||
|
||||
On MacOS X 10.5 and later systems, you can create libraries and
|
||||
executables that work on multiple system types--known as "fat" or
|
||||
"universal" binaries--by specifying multiple `-arch' options to the
|
||||
compiler but only a single `-arch' option to the preprocessor. Like
|
||||
this:
|
||||
|
||||
./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
|
||||
CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
|
||||
CPP="gcc -E" CXXCPP="g++ -E"
|
||||
|
||||
This is not guaranteed to produce working output in all cases, you
|
||||
may have to build one architecture at a time and combine the results
|
||||
using the `lipo' tool if you have problems.
|
||||
|
||||
Installation Names
|
||||
==================
|
||||
|
||||
By default, `make install' installs the package's commands under
|
||||
`/usr/local/bin', include files under `/usr/local/include', etc. You
|
||||
can specify an installation prefix other than `/usr/local' by giving
|
||||
`configure' the option `--prefix=PREFIX', where PREFIX must be an
|
||||
absolute file name.
|
||||
|
||||
You can specify separate installation prefixes for
|
||||
architecture-specific files and architecture-independent files. If you
|
||||
pass the option `--exec-prefix=PREFIX' to `configure', the package uses
|
||||
PREFIX as the prefix for installing programs and libraries.
|
||||
Documentation and other data files still use the regular prefix.
|
||||
|
||||
In addition, if you use an unusual directory layout you can give
|
||||
options like `--bindir=DIR' 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. In general, the
|
||||
default for these options is expressed in terms of `${prefix}', so that
|
||||
specifying just `--prefix' will affect all of the other directory
|
||||
specifications that were not explicitly provided.
|
||||
|
||||
The most portable way to affect installation locations is to pass the
|
||||
correct locations to `configure'; however, many packages provide one or
|
||||
both of the following shortcuts of passing variable assignments to the
|
||||
`make install' command line to change installation locations without
|
||||
having to reconfigure or recompile.
|
||||
|
||||
The first method involves providing an override variable for each
|
||||
affected directory. For example, `make install
|
||||
prefix=/alternate/directory' will choose an alternate location for all
|
||||
directory configuration variables that were expressed in terms of
|
||||
`${prefix}'. Any directories that were specified during `configure',
|
||||
but not in terms of `${prefix}', must each be overridden at install
|
||||
time for the entire installation to be relocated. The approach of
|
||||
makefile variable overrides for each directory variable is required by
|
||||
the GNU Coding Standards, and ideally causes no recompilation.
|
||||
However, some platforms have known limitations with the semantics of
|
||||
shared libraries that end up requiring recompilation when using this
|
||||
method, particularly noticeable in packages that use GNU Libtool.
|
||||
|
||||
The second method involves providing the `DESTDIR' variable. For
|
||||
example, `make install DESTDIR=/alternate/directory' will prepend
|
||||
`/alternate/directory' before all installation names. The approach of
|
||||
`DESTDIR' overrides is not required by the GNU Coding Standards, and
|
||||
does not work on platforms that have drive letters. On the other hand,
|
||||
it does better at avoiding recompilation issues, and works well even
|
||||
when some directory options were not specified in terms of `${prefix}'
|
||||
at `configure' time.
|
||||
|
||||
Optional Features
|
||||
=================
|
||||
|
||||
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'.
|
||||
|
||||
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.
|
||||
|
||||
Some packages offer the ability to configure how verbose the
|
||||
execution of `make' will be. For these packages, running `./configure
|
||||
--enable-silent-rules' sets the default to minimal output, which can be
|
||||
overridden with `make V=1'; while running `./configure
|
||||
--disable-silent-rules' sets the default to verbose, which can be
|
||||
overridden with `make V=0'.
|
||||
|
||||
Particular systems
|
||||
==================
|
||||
|
||||
On HP-UX, the default C compiler is not ANSI C compatible. If GNU
|
||||
CC is not installed, it is recommended to use the following options in
|
||||
order to use an ANSI C compiler:
|
||||
|
||||
./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
|
||||
|
||||
and if that doesn't work, install pre-built binaries of GCC for HP-UX.
|
||||
|
||||
On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
|
||||
parse its `<wchar.h>' header file. The option `-nodtk' can be used as
|
||||
a workaround. If GNU CC is not installed, it is therefore recommended
|
||||
to try
|
||||
|
||||
./configure CC="cc"
|
||||
|
||||
and if that doesn't work, try
|
||||
|
||||
./configure CC="cc -nodtk"
|
||||
|
||||
On Solaris, don't put `/usr/ucb' early in your `PATH'. This
|
||||
directory contains several dysfunctional programs; working variants of
|
||||
these programs are available in `/usr/bin'. So, if you need `/usr/ucb'
|
||||
in your `PATH', put it _after_ `/usr/bin'.
|
||||
|
||||
On Haiku, software installed for all users goes in `/boot/common',
|
||||
not `/usr/local'. It is recommended to use the following options:
|
||||
|
||||
./configure --prefix=/boot/common
|
||||
|
||||
Specifying the System Type
|
||||
==========================
|
||||
|
||||
There may be some features `configure' cannot figure out
|
||||
automatically, but needs to determine by the type of machine the package
|
||||
will run on. Usually, assuming the package is built to be run on the
|
||||
_same_ architectures, `configure' can figure that out, but if it prints
|
||||
a message saying it cannot guess the machine type, give it the
|
||||
`--build=TYPE' option. TYPE can either be a short name for the system
|
||||
type, such as `sun4', or a canonical name which has the form:
|
||||
|
||||
CPU-COMPANY-SYSTEM
|
||||
|
||||
where SYSTEM can have one of these forms:
|
||||
|
||||
OS
|
||||
KERNEL-OS
|
||||
|
||||
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 machine type.
|
||||
|
||||
If you are _building_ compiler tools for cross-compiling, you should
|
||||
use the option `--target=TYPE' to select the type of system they will
|
||||
produce code for.
|
||||
|
||||
If you want to _use_ a cross compiler, that generates code for a
|
||||
platform different from the build platform, you should specify the
|
||||
"host" platform (i.e., that on which the generated programs will
|
||||
eventually be run) with `--host=TYPE'.
|
||||
|
||||
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.
|
||||
|
||||
Defining Variables
|
||||
==================
|
||||
|
||||
Variables not defined in a site shell script can be set in the
|
||||
environment passed to `configure'. However, some packages may run
|
||||
configure again during the build, and the customized values of these
|
||||
variables may be lost. In order to avoid this problem, you should set
|
||||
them in the `configure' command line, using `VAR=value'. For example:
|
||||
|
||||
./configure CC=/usr/local2/bin/gcc
|
||||
|
||||
causes the specified `gcc' to be used as the C compiler (unless it is
|
||||
overridden in the site shell script).
|
||||
|
||||
Unfortunately, this technique does not work for `CONFIG_SHELL' due to
|
||||
an Autoconf bug. Until the bug is fixed you can use this workaround:
|
||||
|
||||
CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
|
||||
|
||||
`configure' Invocation
|
||||
======================
|
||||
|
||||
`configure' recognizes the following options to control how it
|
||||
operates.
|
||||
|
||||
`--help'
|
||||
`-h'
|
||||
Print a summary of all of the options to `configure', and exit.
|
||||
|
||||
`--help=short'
|
||||
`--help=recursive'
|
||||
Print a summary of the options unique to this package's
|
||||
`configure', and exit. The `short' variant lists options used
|
||||
only in the top level, while the `recursive' variant lists options
|
||||
also present in any nested packages.
|
||||
|
||||
`--version'
|
||||
`-V'
|
||||
Print the version of Autoconf used to generate the `configure'
|
||||
script, and exit.
|
||||
|
||||
`--cache-file=FILE'
|
||||
Enable the cache: use and save the results of the tests in FILE,
|
||||
traditionally `config.cache'. FILE defaults to `/dev/null' to
|
||||
disable caching.
|
||||
|
||||
`--config-cache'
|
||||
`-C'
|
||||
Alias for `--cache-file=config.cache'.
|
||||
|
||||
`--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.
|
||||
|
||||
`--prefix=DIR'
|
||||
Use DIR as the installation prefix. *note Installation Names::
|
||||
for more details, including other options available for fine-tuning
|
||||
the installation locations.
|
||||
|
||||
`--no-create'
|
||||
`-n'
|
||||
Run the configure checks, but stop before creating any output
|
||||
files.
|
||||
|
||||
`configure' also accepts some other, not widely useful, options. Run
|
||||
`configure --help' for more details.

XZ Utils Release Notes
|
||||
======================
|
||||
|
||||
5.2.2 (2015-09-29)
|
||||
|
||||
* Fixed bugs in QNX-specific code.
|
||||
|
||||
* Omitted the use of pipe2() even if it is available to avoid
|
||||
portability issues with some old Linux and glibc combinations.
|
||||
|
||||
* Updated German translation.
|
||||
|
||||
* Added project files to build static and shared liblzma (not the
|
||||
whole XZ Utils) with Visual Studio 2013 update 2 or later.
|
||||
|
||||
* Documented that threaded decompression hasn't been implemented
|
||||
yet. A 5.2.0 NEWS entry describing multi-threading support had
|
||||
incorrectly said "decompression" when it should have said
|
||||
"compression".
|
||||
|
||||
|
||||
5.2.1 (2015-02-26)
|
||||
|
||||
* Fixed a compression-ratio regression in fast mode of LZMA1 and
|
||||
LZMA2. The bug is present in 5.1.4beta and 5.2.0 releases.
|
||||
|
||||
* Fixed a portability problem in xz that affected at least OpenBSD.
|
||||
|
||||
* Fixed xzdiff to be compatible with FreeBSD's mktemp which differs
|
||||
from most other mktemp implementations.
|
||||
|
||||
* Changed CPU core count detection to use cpuset_getaffinity() on
|
||||
FreeBSD.
|
||||
|
||||
|
||||
5.2.0 (2014-12-21)
|
||||
|
||||
Since 5.1.4beta:
|
||||
|
||||
* All fixes from 5.0.8
|
||||
|
||||
* liblzma: Fixed lzma_stream_encoder_mt_memusage() when a preset
|
||||
was used.
|
||||
|
||||
* xzdiff: If mktemp isn't installed, mkdir will be used as
|
||||
a fallback to create a temporary directory. Installing mktemp
|
||||
is still recommended.
|
||||
|
||||
* Updated French, German, Italian, Polish, and Vietnamese
|
||||
translations.
|
||||
|
||||
Summary of fixes and new features added in the 5.1.x development
|
||||
releases:
|
||||
|
||||
* liblzma:
|
||||
|
||||
- Added support for multi-threaded compression. See the
|
||||
lzma_mt structure, lzma_stream_encoder_mt(), and
|
||||
lzma_stream_encoder_mt_memusage() in <lzma/container.h>,
|
||||
lzma_get_progress() in <lzma/base.h>, and lzma_cputhreads()
|
||||
in <lzma/hardware.h> for details.
|
||||
|
||||
- Made the uses of lzma_allocator const correct.
|
||||
|
||||
- Added lzma_block_uncomp_encode() to create uncompressed
|
||||
.xz Blocks using LZMA2 uncompressed chunks.
|
||||
|
||||
- Added support for LZMA_IGNORE_CHECK.
|
||||
|
||||
- A few speed optimizations were made.
|
||||
|
||||
- Added support for symbol versioning. It is enabled by default
|
||||
on GNU/Linux, other GNU-based systems, and FreeBSD.
|
||||
|
||||
- liblzma (not the whole XZ Utils) should now be buildable
|
||||
with MSVC 2013 update 2 or later using windows/config.h.
|
||||
|
||||
* xz:
|
||||
|
||||
- Fixed a race condition in the signal handling. It was
|
||||
possible that e.g. the first SIGINT didn't make xz exit
|
||||
if reading or writing blocked and one had bad luck. The fix
|
||||
is non-trivial, so as of writing it is unknown if it will be
|
||||
backported to the v5.0 branch.
|
||||
|
||||
- Multi-threaded compression can be enabled with the
|
||||
--threads (-T) option.
|
||||
[Fixed: This originally said "decompression".]
|
||||
|
||||
- New command line options in xz: --single-stream,
|
||||
--block-size=SIZE, --block-list=SIZES,
|
||||
--flush-timeout=TIMEOUT, and --ignore-check.
|
||||
|
||||
- xz -lvv now shows the minimum xz version that is required to
|
||||
decompress the file. Currently it is 5.0.0 for all supported
|
||||
.xz files except files with empty LZMA2 streams require 5.0.2.
|
||||
|
||||
* xzdiff and xzgrep now support .lzo files if lzop is installed.
|
||||
The .tzo suffix is also recognized as a shorthand for .tar.lzo.
|
||||
|
||||
|
||||
5.1.4beta (2014-09-14)
|
||||
|
||||
* All fixes from 5.0.6
|
||||
|
||||
* liblzma: Fixed the use of presets in threaded encoder
|
||||
initialization.
|
||||
|
||||
* xz --block-list and --block-size can now be used together
|
||||
in single-threaded mode. Previously the combination only
|
||||
worked in multi-threaded mode.
|
||||
|
||||
* Added support for LZMA_IGNORE_CHECK to liblzma and made it
|
||||
available in xz as --ignore-check.
|
||||
|
||||
* liblzma speed optimizations:
|
||||
|
||||
- Initialization of a new LZMA1 or LZMA2 encoder has been
|
||||
optimized. (The speed of reinitializing an already-allocated
|
||||
encoder isn't affected.) This helps when compressing many
|
||||
small buffers with lzma_stream_buffer_encode() and other
|
||||
similar situations where an already-allocated encoder state
|
||||
isn't reused. This speed-up is visible in xz too if one
|
||||
compresses many small files one at a time instead running xz
|
||||
once and giving all files as command-line arguments.
|
||||
|
||||
- Buffer comparisons are now much faster when unaligned access
|
||||
is allowed (configured with --enable-unaligned-access). This
|
||||
speeds up encoding significantly. There is arch-specific code
|
||||
for 32-bit and 64-bit x86 (32-bit needs SSE2 for the best
|
||||
results and there's no run-time CPU detection for now).
|
||||
For other archs there is only generic code which probably
|
||||
isn't as optimal as arch-specific solutions could be.
|
||||
|
||||
- A few speed optimizations were made to the SHA-256 code.
|
||||
(Note that the builtin SHA-256 code isn't used on all
|
||||
operating systems.)
|
||||
|
||||
* liblzma can now be built with MSVC 2013 update 2 or later
|
||||
using windows/config.h.
|
||||
|
||||
* Vietnamese translation was added.
|
||||
|
||||
|
||||
5.1.3alpha (2013-10-26)
|
||||
|
||||
* All fixes from 5.0.5
|
||||
|
||||
* liblzma:
|
||||
|
||||
- Fixed a deadlock in the threaded encoder.
|
||||
|
||||
- Made the uses of lzma_allocator const correct.
|
||||
|
||||
- Added lzma_block_uncomp_encode() to create uncompressed
|
||||
.xz Blocks using LZMA2 uncompressed chunks.
|
||||
|
||||
- Added support for native threads on Windows and the ability
|
||||
to detect the number of CPU cores.
|
||||
|
||||
* xz:
|
||||
|
||||
- Fixed a race condition in the signal handling. It was
|
||||
possible that e.g. the first SIGINT didn't make xz exit
|
||||
if reading or writing blocked and one had bad luck. The fix
|
||||
is non-trivial, so as of writing it is unknown if it will be
|
||||
backported to the v5.0 branch.
|
||||
|
||||
- Made the progress indicator work correctly in threaded mode.
|
||||
|
||||
- Threaded encoder now works together with --block-list=SIZES.
|
||||
|
||||
- Added preliminary support for --flush-timeout=TIMEOUT.
|
||||
It can be useful for (somewhat) real-time streaming. For
|
||||
now the decompression side has to be done with something
|
||||
else than the xz tool due to how xz does buffering, but this
|
||||
should be fixed.
|
||||
|
||||
|
||||
5.1.2alpha (2012-07-04)
|
||||
|
||||
* All fixes from 5.0.3 and 5.0.4
|
||||
|
||||
* liblzma:
|
||||
|
||||
- Fixed a deadlock and an invalid free() in the threaded encoder.
|
||||
|
||||
- Added support for symbol versioning. It is enabled by default
|
||||
on GNU/Linux, other GNU-based systems, and FreeBSD.
|
||||
|
||||
- Use SHA-256 implementation from the operating system if one is
|
||||
available in libc, libmd, or libutil. liblzma won't use e.g.
|
||||
OpenSSL or libgcrypt to avoid introducing new dependencies.
|
||||
|
||||
- Fixed liblzma.pc for static linking.
|
||||
|
||||
- Fixed a few portability bugs.
|
||||
|
||||
* xz --decompress --single-stream now fixes the input position after
|
||||
successful decompression. Now the following works:
|
||||
|
||||
echo foo | xz > foo.xz
|
||||
echo bar | xz >> foo.xz
|
||||
( xz -dc --single-stream ; xz -dc --single-stream ) < foo.xz
|
||||
|
||||
Note that it doesn't work if the input is not seekable
|
||||
or if there is Stream Padding between the concatenated
|
||||
.xz Streams.
|
||||
|
||||
* xz -lvv now shows the minimum xz version that is required to
|
||||
decompress the file. Currently it is 5.0.0 for all supported .xz
|
||||
files except files with empty LZMA2 streams require 5.0.2.
|
||||
|
||||
* Added an *incomplete* implementation of --block-list=SIZES to xz.
|
||||
It only works correctly in single-threaded mode and when
|
||||
--block-size isn't used at the same time. --block-list allows
|
||||
specifying the sizes of Blocks which can be useful e.g. when
|
||||
creating files for random-access reading.
|
||||
|
||||
|
||||
5.1.1alpha (2011-04-12)
|
||||
|
||||
* All fixes from 5.0.2
|
||||
|
||||
* liblzma fixes that will also be included in 5.0.3:
|
||||
|
||||
- A memory leak was fixed.
|
||||
|
||||
- lzma_stream_buffer_encode() no longer creates an empty .xz
|
||||
Block if encoding an empty buffer. Such an empty Block with
|
||||
LZMA2 data would trigger a bug in 5.0.1 and older (see the
|
||||
first bullet point in 5.0.2 notes). When releasing 5.0.2,
|
||||
I thought that no encoder creates this kind of files but
|
||||
I was wrong.
|
||||
|
||||
- Validate function arguments better in a few functions. Most
|
||||
importantly, specifying an unsupported integrity check to
|
||||
lzma_stream_buffer_encode() no longer creates a corrupt .xz
|
||||
file. Probably no application tries to do that, so this
|
||||
shouldn't be a big problem in practice.
|
||||
|
||||
- Document that lzma_block_buffer_encode(),
|
||||
lzma_easy_buffer_encode(), lzma_stream_encoder(), and
|
||||
lzma_stream_buffer_encode() may return LZMA_UNSUPPORTED_CHECK.
|
||||
|
||||
- The return values of the _memusage() functions are now
|
||||
documented better.
|
||||
|
||||
* Support for multithreaded compression was added using the simplest
|
||||
method, which splits the input data into blocks and compresses
|
||||
them independently. Other methods will be added in the future.
|
||||
The current method has room for improvement, e.g. it is possible
|
||||
to reduce the memory usage.
|
||||
|
||||
* Added the options --single-stream and --block-size=SIZE to xz.
|
||||
|
||||
* xzdiff and xzgrep now support .lzo files if lzop is installed.
|
||||
The .tzo suffix is also recognized as a shorthand for .tar.lzo.
|
||||
|
||||
* Support for short 8.3 filenames under DOS was added to xz. It is
|
||||
experimental and may change before it gets into a stable release.
|
||||
|
||||
|
||||
5.0.8 (2014-12-21)
|
||||
|
||||
* Fixed an old bug in xzgrep that affected OpenBSD and probably
|
||||
a few other operating systems too.
|
||||
|
||||
* Updated French and German translations.
|
||||
|
||||
* Added support for detecting the amount of RAM on AmigaOS/AROS.
|
||||
|
||||
* Minor build system updates.
|
||||
|
||||
|
||||
5.0.7 (2014-09-20)
|
||||
|
||||
* Fix regressions introduced in 5.0.6:
|
||||
|
||||
- Fix building with non-GNU make.
|
||||
|
||||
- Fix invalid Libs.private value in liblzma.pc which broke
|
||||
static linking against liblzma if the linker flags were
|
||||
taken from pkg-config.
|
||||
|
||||
|
||||
5.0.6 (2014-09-14)
|
||||
|
||||
* xzgrep now exits with status 0 if at least one file matched.
|
||||
|
||||
* A few minor portability and build system fixes
|
||||
|
||||
|
||||
5.0.5 (2013-06-30)
|
||||
|
||||
* lzmadec and liblzma's lzma_alone_decoder(): Support decompressing
|
||||
.lzma files that have less common settings in the headers
|
||||
(dictionary size other than 2^n or 2^n + 2^(n-1), or uncompressed
|
||||
size greater than 256 GiB). The limitations existed to avoid false
|
||||
positives when detecting .lzma files. The lc + lp <= 4 limitation
|
||||
still remains since liblzma's LZMA decoder has that limitation.
|
||||
|
||||
NOTE: xz's .lzma support or liblzma's lzma_auto_decoder() are NOT
|
||||
affected by this change. They still consider uncommon .lzma headers
|
||||
as not being in the .lzma format. Changing this would give way too
|
||||
many false positives.
|
||||
|
||||
* xz:
|
||||
|
||||
- Interaction of preset and custom filter chain options was
|
||||
made less illogical. This affects only certain less typical
|
||||
uses cases so few people are expected to notice this change.
|
||||
|
||||
Now when a custom filter chain option (e.g. --lzma2) is
|
||||
specified, all preset options (-0 ... -9, -e) earlier are on
|
||||
the command line are completely forgotten. Similarly, when
|
||||
a preset option is specified, all custom filter chain options
|
||||
earlier on the command line are completely forgotten.
|
||||
|
||||
Example 1: "xz -9 --lzma2=preset=5 -e" is equivalent to "xz -e"
|
||||
which is equivalent to "xz -6e". Earlier -e didn't put xz back
|
||||
into preset mode and thus the example command was equivalent
|
||||
to "xz --lzma2=preset=5".
|
||||
|
||||
Example 2: "xz -9e --lzma2=preset=5 -7" is equivalent to
|
||||
"xz -7". Earlier a custom filter chain option didn't make
|
||||
xz forget the -e option so the example was equivalent to
|
||||
"xz -7e".
|
||||
|
||||
- Fixes and improvements to error handling.
|
||||
|
||||
- Various fixes to the man page.
|
||||
|
||||
* xzless: Fixed to work with "less" versions 448 and later.
|
||||
|
||||
* xzgrep: Made -h an alias for --no-filename.
|
||||
|
||||
* Include the previously missing debug/translation.bash which can
|
||||
be useful for translators.
|
||||
|
||||
* Include a build script for Mac OS X. This has been in the Git
|
||||
repository since 2010 but due to a mistake in Makefile.am the
|
||||
script hasn't been included in a release tarball before.
|
||||
|
||||
|
||||
5.0.4 (2012-06-22)
|
||||
|
||||
* liblzma:
|
||||
|
||||
- Fix lzma_index_init(). It could crash if memory allocation
|
||||
failed.
|
||||
|
||||
- Fix the possibility of an incorrect LZMA_BUF_ERROR when a BCJ
|
||||
filter is used and the application only provides exactly as
|
||||
much output space as is the uncompressed size of the file.
|
||||
|
||||
- Fix a bug in doc/examples_old/xz_pipe_decompress.c. It didn't
|
||||
check if the last call to lzma_code() really returned
|
||||
LZMA_STREAM_END, which made the program think that truncated
|
||||
files are valid.
|
||||
|
||||
- New example programs in doc/examples (old programs are now in
|
||||
doc/examples_old). These have more comments and more detailed
|
||||
error handling.
|
||||
|
||||
* Fix "xz -lvv foo.xz". It could crash on some corrupted files.
|
||||
|
||||
* Fix output of "xz --robot -lv" and "xz --robot -lvv" which
|
||||
incorrectly printed the filename also in the "foo (x/x)" format.
|
||||
|
||||
* Fix exit status of "xzdiff foo.xz bar.xz".
|
||||
|
||||
* Fix exit status of "xzgrep foo binary_file".
|
||||
|
||||
* Fix portability to EBCDIC systems.
|
||||
|
||||
* Fix a configure issue on AIX with the XL C compiler. See INSTALL
|
||||
for details.
|
||||
|
||||
* Update French, German, Italian, and Polish translations.
|
||||
|
||||
|
||||
5.0.3 (2011-05-21)
|
||||
|
||||
* liblzma fixes:
|
||||
|
||||
- A memory leak was fixed.
|
||||
|
||||
- lzma_stream_buffer_encode() no longer creates an empty .xz
|
||||
Block if encoding an empty buffer. Such an empty Block with
|
||||
LZMA2 data would trigger a bug in 5.0.1 and older (see the
|
||||
first bullet point in 5.0.2 notes). When releasing 5.0.2,
|
||||
I thought that no encoder creates this kind of files but
|
||||
I was wrong.
|
||||
|
||||
- Validate function arguments better in a few functions. Most
|
||||
importantly, specifying an unsupported integrity check to
|
||||
lzma_stream_buffer_encode() no longer creates a corrupt .xz
|
||||
file. Probably no application tries to do that, so this
|
||||
shouldn't be a big problem in practice.
|
||||
|
||||
- Document that lzma_block_buffer_encode(),
|
||||
lzma_easy_buffer_encode(), lzma_stream_encoder(), and
|
||||
lzma_stream_buffer_encode() may return LZMA_UNSUPPORTED_CHECK.
|
||||
|
||||
- The return values of the _memusage() functions are now
|
||||
documented better.
|
||||
|
||||
* Fix command name detection in xzgrep. xzegrep and xzfgrep now
|
||||
correctly use egrep and fgrep instead of grep.
|
||||
|
||||
* French translation was added.
|
||||
|
||||
|
||||
5.0.2 (2011-04-01)
|
||||
|
||||
* LZMA2 decompressor now correctly accepts LZMA2 streams with no
|
||||
uncompressed data. Previously it considered them corrupt. The
|
||||
bug can affect applications that use raw LZMA2 streams. It is
|
||||
very unlikely to affect .xz files because no compressor creates
|
||||
.xz files with empty LZMA2 streams. (Empty .xz files are a
|
||||
different thing than empty LZMA2 streams.)
|
||||
|
||||
* "xz --suffix=.foo filename.foo" now refuses to compress the
|
||||
file due to it already having the suffix .foo. It was already
|
||||
documented on the man page, but the code lacked the test.
|
||||
|
||||
* "xzgrep -l foo bar.xz" works now.
|
||||
|
||||
* Polish translation was added.
|
||||
|
||||
|
||||
5.0.1 (2011-01-29)
|
||||
|
||||
* xz --force now (de)compresses files that have setuid, setgid,
|
||||
or sticky bit set and files that have multiple hard links.
|
||||
The man page had it documented this way already, but the code
|
||||
had a bug.
|
||||
|
||||
* gzip and bzip2 support in xzdiff was fixed.
|
||||
|
||||
* Portability fixes
|
||||
|
||||
* Minor fix to Czech translation
|
||||
|
||||
|
||||
5.0.0 (2010-10-23)
|
||||
|
||||
Only the most important changes compared to 4.999.9beta are listed
|
||||
here. One change is especially important:
|
||||
|
||||
* The memory usage limit is now disabled by default. Some scripts
|
||||
written before this change may have used --memory=max on xz command
|
||||
line or in XZ_OPT. THESE USES OF --memory=max SHOULD BE REMOVED
|
||||
NOW, because they interfere with user's ability to set the memory
|
||||
usage limit himself. If user-specified limit causes problems to
|
||||
your script, blame the user.
|
||||
|
||||
Other significant changes:
|
||||
|
||||
* Added support for XZ_DEFAULTS environment variable. This variable
|
||||
allows users to set default options for xz, e.g. default memory
|
||||
usage limit or default compression level. Scripts that use xz
|
||||
must never set or unset XZ_DEFAULTS. Scripts should use XZ_OPT
|
||||
instead if they need a way to pass options to xz via an
|
||||
environment variable.
|
||||
|
||||
* The compression settings associated with the preset levels
|
||||
-0 ... -9 have been changed. --extreme was changed a little too.
|
||||
It is now less likely to make compression worse, but with some
|
||||
files the new --extreme may compress slightly worse than the old
|
||||
--extreme.
|
||||
|
||||
* If a preset level (-0 ... -9) is specified after a custom filter
|
||||
chain options have been used (e.g. --lzma2), the custom filter
|
||||
chain will be forgotten. Earlier the preset options were
|
||||
completely ignored after custom filter chain options had been
|
||||
seen.
|
||||
|
||||
* xz will create sparse files when decompressing if the uncompressed
|
||||
data contains long sequences of binary zeros. This is done even
|
||||
when writing to standard output that is connected to a regular
|
||||
file and certain additional conditions are met to make it safe.
|
||||
|
||||
* Support for "xz --list" was added. Combine with --verbose or
|
||||
--verbose --verbose (-vv) for detailed output.
|
||||
|
||||
* I had hoped that liblzma API would have been stable after
|
||||
4.999.9beta, but there have been a couple of changes in the
|
||||
advanced features, which don't affect most applications:
|
||||
|
||||
- Index handling code was revised. If you were using the old
|
||||
API, you will get a compiler error (so it's easy to notice).
|
||||
|
||||
- A subtle but important change was made to the Block handling
|
||||
API. lzma_block.version has to be initialized even for
|
||||
lzma_block_header_decode(). Code that doesn't do it will work
|
||||
for now, but might break in the future, which makes this API
|
||||
change easy to miss.
|
||||
|
||||
* The major soname has been bumped to 5.0.0. liblzma API and ABI
|
||||
are now stable, so the need to recompile programs linking against
|
||||
liblzma shouldn't arise soon.

0. Preface
|
||||
----------
|
||||
|
||||
This document is meant for people who create and maintain XZ Utils
|
||||
packages for operating system distributions. The focus is on GNU/Linux
|
||||
systems, but most things apply to other systems too.
|
||||
|
||||
While the standard "configure && make DESTDIR=$PKG install" should
|
||||
give a pretty good package, there are some details which packagers
|
||||
may want to tweak.
|
||||
|
||||
Packagers should also read the INSTALL file.
|
||||
|
||||
|
||||
1. Package naming
|
||||
-----------------
|
||||
|
||||
The preferred name for the XZ Utils package is "xz", because that's
|
||||
the name of the upstream tarball. Naturally you may have good reasons
|
||||
to use some other name; I won't get angry about it. ;-) It's just nice
|
||||
to be able to point people to the correct package name without asking
|
||||
what distro they have.
|
||||
|
||||
If your distro policy is to split things into small pieces, here is
|
||||
one suggestion:
|
||||
|
||||
xz xz, xzdec, scripts (xzdiff, xzgrep, etc.), docs
|
||||
xz-lzma lzma, unlzma, lzcat, lzgrep etc. symlinks and
|
||||
lzmadec binary for compatibility with LZMA Utils
|
||||
liblzma liblzma.so.*
|
||||
liblzma-devel liblzma.so, liblzma.a, API headers
|
||||
|
||||
|
||||
2. Package description
|
||||
----------------------
|
||||
|
||||
Here is a suggestion which you may use as the package description.
|
||||
If you can use only one-line description, pick only the first line.
|
||||
Naturally, feel free to use some other description if you find it
|
||||
better, and maybe send it to me too.
|
||||
|
||||
Library and command line tools for XZ and LZMA compressed files
|
||||
|
||||
XZ Utils provide a general purpose data compression library
|
||||
and command line tools. The native file format is the .xz
|
||||
format, but also the legacy .lzma format is supported. The .xz
|
||||
format supports multiple compression algorithms, of which LZMA2
|
||||
is currently the primary algorithm. With typical files, XZ Utils
|
||||
create about 30 % smaller files than gzip.
|
||||
|
||||
If you are splitting XZ Utils into multiple packages, here are some
|
||||
suggestions for package descriptions:
|
||||
|
||||
xz:
|
||||
|
||||
Command line tools for XZ and LZMA compressed files
|
||||
|
||||
This package includes the xz compression tool and other command
|
||||
line tools from XZ Utils. xz has command line syntax similar to
|
||||
that of gzip. The native file format is the .xz format, but also
|
||||
the legacy .lzma format is supported. The .xz format supports
|
||||
multiple compression algorithms, of which LZMA2 is currently the
|
||||
primary algorithm. With typical files, XZ Utils create about 30 %
|
||||
smaller files than gzip.
|
||||
|
||||
Note that this package doesn't include the files needed for
|
||||
LZMA Utils 4.32.x compatibility. Install also the xz-lzma
|
||||
package to make XZ Utils emulate LZMA Utils 4.32.x.
|
||||
|
||||
xz-lzma:
|
||||
|
||||
LZMA Utils emulation with XZ Utils
|
||||
|
||||
This package includes executables and symlinks to make
|
||||
XZ Utils emulate lzma, unlzma, lzcat, and other command
|
||||
line tools found from the legacy LZMA Utils 4.32.x package.
|
||||
|
||||
liblzma:
|
||||
|
||||
Library for XZ and LZMA compressed files
|
||||
|
||||
liblzma is a general purpose data compression library with
|
||||
an API similar to that of zlib. liblzma supports multiple
|
||||
algorithms, of which LZMA2 is currently the primary algorithm.
|
||||
The native file format is .xz, but also the legacy .lzma
|
||||
format and raw streams (no headers at all) are supported.
|
||||
|
||||
This package includes the shared library.
|
||||
|
||||
liblzma-devel:
|
||||
|
||||
Library for XZ and LZMA compressed files
|
||||
|
||||
This package includes the API headers, static library, and
|
||||
other development files related to liblzma.
|
||||
|
||||
|
||||
3. License
|
||||
----------
|
||||
|
||||
If the package manager supports a license field, you probably should
|
||||
put GPLv2+ there (GNU GPL v2 or later). The interesting parts of
|
||||
XZ Utils are in the public domain, but some less important files
|
||||
ending up into the binary package are under GPLv2+. So it is simplest
|
||||
to just say GPLv2+ if you cannot specify "public domain and GPLv2+".
|
||||
|
||||
If you split XZ Utils into multiple packages as described earlier
|
||||
in this file, liblzma and liblzma-dev packages will contain only
|
||||
public domain code (from XZ Utils at least; compiler or linker may
|
||||
add some third-party code, which may be copyrighted).
|
||||
|
||||
|
||||
4. configure options
|
||||
--------------------
|
||||
|
||||
Unless you are building a package for a distribution that is meant
|
||||
only for embedded systems, don't use the following configure options:
|
||||
|
||||
--enable-debug
|
||||
--enable-encoders (*)
|
||||
--enable-decoders
|
||||
--enable-match-finders
|
||||
--enable-checks
|
||||
--enable-small (*)
|
||||
--disable-threads (*)
|
||||
|
||||
(*) These are OK when building xzdec and lzmadec as described
|
||||
in INSTALL.
|
||||
|
||||
xzdec and lzmadec don't provide any functionality that isn't already
|
||||
available in the xz tool. Shipping xzdec and lzmadec without size
|
||||
optimization and statically-linked liblzma isn't very useful. Doing
|
||||
that would give users the xzdec man page, which may make it easier
|
||||
for people to find out that such tools exists, but the executables
|
||||
wouldn't have any advantage over the full-featured xz.
|
||||
|
||||
|
||||
5. Additional documentation
|
||||
---------------------------
|
||||
|
||||
"make install" copies some additional documentation to $docdir
|
||||
(--docdir in configure). There is a copy of the GNU GPL v2, which
|
||||
can be replaced with a symlink if your distro ships with shared
|
||||
copies of the common license texts.
|
||||
|
||||
liblzma API is currently only documented using Doxygen tags in the
|
||||
API headers. It hasn't been tested much how good results Doxygen
|
||||
is able to make from the tags (e.g. Doxyfile might need tweaking,
|
||||
the tagging may need to be improved etc.), so it might be simpler
|
||||
to just let people read docs directly from the .h files for now,
|
||||
and also save quite a bit in package size at the same time.
|
||||
|
||||
|
||||
6. Extra files
|
||||
--------------
|
||||
|
||||
The "extra" directory contains some small extra tools or other files.
|
||||
The exact set of extra files can vary between XZ Utils releases. The
|
||||
extra files have only limited use or they are too dangerous to be
|
||||
put directly to $bindir (7z2lzma.sh is a good example, since it can
|
||||
silently create corrupt output if certain conditions are not met).
|
||||
|
||||
If you feel like it, you may copy the extra directory under the doc
|
||||
directory (e.g. /usr/share/doc/xz/extra). Maybe some people will find
|
||||
them useful. However, most people needing these tools probably are
|
||||
able to find them from the source package too.
|
||||
|
||||
The "debug" directory contains some tools that are useful only when
|
||||
hacking on XZ Utils. Don't package these tools.
|
||||
|
||||
|
||||
7. Installing XZ Utils and LZMA Utils in parallel
|
||||
-------------------------------------------------
|
||||
|
||||
XZ Utils and LZMA Utils 4.32.x can be installed in parallel by
|
||||
omitting the compatibility symlinks (lzma, unlzma, lzcat, lzgrep etc.)
|
||||
from the XZ Utils package. It's probably a good idea to still package
|
||||
the symlinks into a separate package so that users may choose if they
|
||||
want to use XZ Utils or LZMA Utils for handling .lzma files.
|
||||
|
||||
|
||||
8. Example
|
||||
----------
|
||||
|
||||
Here is an example for i686 GNU/Linux that
|
||||
- links xz and lzmainfo against shared liblzma;
|
||||
- links size-optimized xzdec and lzmadec against static liblzma
|
||||
while avoiding libpthread dependency;
|
||||
- includes only shared liblzma in the final package; and
|
||||
- copies also the "extra" directory to the package.
|
||||
|
||||
PKG=/tmp/xz-pkg
|
||||
tar xf xz-x.y.z.tar.gz
|
||||
cd xz-x.y.z
|
||||
./configure \
|
||||
--prefix=/usr \
|
||||
--disable-static \
|
||||
--disable-xzdec \
|
||||
--disable-lzmadec \
|
||||
CFLAGS='-march=i686 -mtune=generic -O2'
|
||||
make
|
||||
make DESTDIR=$PKG install-strip
|
||||
make clean
|
||||
./configure \
|
||||
--prefix=/usr \
|
||||
--disable-shared \
|
||||
--disable-nls \
|
||||
--disable-encoders \
|
||||
--enable-small \
|
||||
--disable-threads \
|
||||
CFLAGS='-march=i686 -mtune=generic -Os'
|
||||
make -C src/liblzma
|
||||
make -C src/xzdec
|
||||
make -C src/xzdec DESTDIR=$PKG install-strip
|
||||
cp -a extra $PKG/usr/share/doc/xz

0. Overview
|
||||
-----------
|
||||
|
||||
XZ Utils provide a general-purpose data-compression library plus
|
||||
command-line tools. The native file format is the .xz format, but
|
||||
also the legacy .lzma format is supported. The .xz format supports
|
||||
multiple compression algorithms, which are called "filters" in the
|
||||
context of XZ Utils. The primary filter is currently LZMA2. With
|
||||
typical files, XZ Utils create about 30 % smaller files than gzip.
|
||||
|
||||
To ease adapting support for the .xz format into existing applications
|
||||
and scripts, the API of liblzma is somewhat similar to the API of the
|
||||
popular zlib library. For the same reason, the command-line tool xz
|
||||
has a command-line syntax similar to that of gzip.
|
||||
|
||||
When aiming for the highest compression ratio, the LZMA2 encoder uses
|
||||
a lot of CPU time and may use, depending on the settings, even
|
||||
hundreds of megabytes of RAM. However, in fast modes, the LZMA2 encoder
|
||||
competes with bzip2 in compression speed, RAM usage, and compression
|
||||
ratio.
|
||||
|
||||
LZMA2 is reasonably fast to decompress. It is a little slower than
|
||||
gzip, but a lot faster than bzip2. Being fast to decompress means
|
||||
that the .xz format is especially nice when the same file will be
|
||||
decompressed very many times (usually on different computers), which
|
||||
is the case e.g. when distributing software packages. In such
|
||||
situations, it's not too bad if the compression takes some time,
|
||||
since that needs to be done only once to benefit many people.
|
||||
|
||||
With some file types, combining (or "chaining") LZMA2 with an
|
||||
additional filter can improve the compression ratio. A filter chain may
|
||||
contain up to four filters, although usually only one or two are used.
|
||||
For example, putting a BCJ (Branch/Call/Jump) filter before LZMA2
|
||||
in the filter chain can improve compression ratio of executable files.
|
||||
|
||||
Since the .xz format allows adding new filter IDs, it is possible that
|
||||
some day there will be a filter that is, for example, much faster to
|
||||
compress than LZMA2 (but probably with worse compression ratio).
|
||||
Similarly, it is possible that some day there is a filter that will
|
||||
compress better than LZMA2.
|
||||
|
||||
XZ Utils doesn't support multithreaded compression or decompression
|
||||
yet. It has been planned though and taken into account when designing
|
||||
the .xz file format.

|
||||
1.2. Documentation for command-line tools
|
||||
|
||||
The command-line tools are documented as man pages. In source code
|
||||
releases (and possibly also in some binary packages), the man pages
|
||||
are also provided in plain text (ASCII only) and PDF formats in the
|
||||
directory "doc/man" to make the man pages more accessible to those
|
||||
whose operating system doesn't provide an easy way to view man pages.
|
||||
|
||||
|
||||
1.3. Documentation for liblzma
|
||||
|
||||
The liblzma API headers include short docs about each function
|
||||
and data type as Doxygen tags. These docs should be quite OK as
|
||||
a quick reference.
|
||||
|
||||
I have planned to write a bunch of very well documented example
|
||||
programs, which (due to comments) should work as a tutorial to
|
||||
various features of liblzma. No such example programs have been
|
||||
written yet.
|
||||
|
||||
For now, if you have never used liblzma, libbzip2, or zlib, I
|
||||
recommend learning the *basics* of the zlib API. Once you know that,
|
||||
it should be easier to learn liblzma.

2. Version numbering
|
||||
--------------------
|
||||
|
||||
The version number format of XZ Utils is X.Y.ZS:
|
||||
|
||||
- X is the major version. When this is incremented, the library
|
||||
API and ABI break.
|
||||
|
||||
- Y is the minor version. It is incremented when new features
|
||||
are added without breaking the existing API or ABI. An even Y
|
||||
indicates a stable release and an odd Y indicates unstable
|
||||
(alpha or beta version).
|
||||
|
||||
- Z is the revision. This has a different meaning for stable and
|
||||
unstable releases:
|
||||
|
||||
* Stable: Z is incremented when bugs get fixed without adding
|
||||
any new features. This is intended to be convenient for
|
||||
downstream distributors that want bug fixes but don't want
|
||||
any new features to minimize the risk of introducing new bugs.
|
||||
|
||||
* Unstable: Z is just a counter. API or ABI of features added
|
||||
in earlier unstable releases having the same X.Y may break.
|
||||
|
||||
- S indicates stability of the release. It is missing from the
|
||||
stable releases, where Y is an even number. When Y is odd, S
|
||||
is either "alpha" or "beta" to make it very clear that such
|
||||
versions are not stable releases. The same X.Y.Z combination is
|
||||
not used for more than one stability level, i.e. after X.Y.Zalpha,
|
||||
the next version can be X.Y.(Z+1)beta but not X.Y.Zbeta.
|
||||
|
||||
|
||||
3. Reporting bugs
|
||||
-----------------
|
||||
|
||||
Naturally it is easiest for me if you already know what causes the
|
||||
unexpected behavior. Even better if you have a patch to propose.
|
||||
However, quite often the reason for unexpected behavior is unknown,
|
||||
so here are a few things to do before sending a bug report:
|
||||
|
||||
1. Try to create a small example how to reproduce the issue.
|
||||
|
||||
2. Compile XZ Utils with debugging code using configure switches
|
||||
--enable-debug and, if possible, --disable-shared. If you are
|
||||
using GCC, use CFLAGS='-O0 -ggdb3'. Don't strip the resulting
|
||||
binaries.
|
||||
|
||||
3. Turn on core dumps. The exact command depends on your shell;
|
||||
for example in GNU bash it is done with "ulimit -c unlimited",
|
||||
and in tcsh with "limit coredumpsize unlimited".
|
||||
|
||||
4. Try to reproduce the suspected bug. If you get "assertion failed"
|
||||
message, be sure to include the complete message in your bug
|
||||
report. If the application leaves a coredump, get a backtrace
|
||||
using gdb:
|
||||
$ gdb /path/to/app-binary # Load the app to the debugger.
|
||||
(gdb) core core # Open the coredump.
|
||||
(gdb) bt # Print the backtrace. Copy & paste to bug report.
|
||||
(gdb) quit # Quit gdb.
|
||||
|
||||
Report your bug via email or IRC (see Contact information below).
|
||||
Don't send core dump files or any executables. If you have a small
|
||||
example file(s) (total size less than 256 KiB), please include
|
||||
it/them as an attachment. If you have bigger test files, put them
|
||||
online somewhere and include a URL to the file(s) in the bug report.
|
||||
|
||||
Always include the exact version number of XZ Utils in the bug report.
|
||||
If you are using a snapshot from the git repository, use "git describe"
|
||||
to get the exact snapshot version. If you are using XZ Utils shipped
|
||||
in an operating system distribution, mention the distribution name,
|
||||
distribution version, and exact xz package version; if you cannot
|
||||
repeat the bug with the code compiled from unpatched source code,
|
||||
you probably need to report a bug to your distribution's bug tracking
|
||||
system.
|
||||
|
||||
|
||||
4. Translating the xz tool
|
||||
--------------------------
|
||||
|
||||
The messages from the xz tool have been translated into a few
|
||||
languages. Before starting to translate into a new language, ask
|
||||
the author whether someone else hasn't already started working on it.
|
||||
|
||||
Test your translation. Testing includes comparing the translated
|
||||
output to the original English version by running the same commands
|
||||
in both your target locale and with LC_ALL=C. Ask someone to
|
||||
proof-read and test the translation.
|
||||
|
||||
Testing can be done e.g. by installing xz into a temporary directory:
|
||||
|
||||
./configure --disable-shared --prefix=/tmp/xz-test
|
||||
# <Edit the .po file in the po directory.>
|
||||
make -C po update-po
|
||||
make install
|
||||
bash debug/translation.bash | less
|
||||
bash debug/translation.bash | less -S # For --list outputs
|
||||
|
||||
Repeat the above as needed (no need to re-run configure though).
|
||||
|
||||
Note especially the following:
|
||||
|
||||
- The output of --help and --long-help must look nice on
|
||||
an 80-column terminal. It's OK to add extra lines if needed.
|
||||
|
||||
- In contrast, don't add extra lines to error messages and such.
|
||||
They are often preceded with e.g. a filename on the same line,
|
||||
so you have no way to predict where to put a \n. Let the terminal
|
||||
do the wrapping even if it looks ugly. Adding new lines will be
|
||||
even uglier in the generic case even if it looks nice in a few
|
||||
limited examples.
|
||||
|
||||
- Be careful with column alignment in tables and table-like output
|
||||
(--list, --list --verbose --verbose, --info-memory, --help, and
|
||||
--long-help):
|
||||
|
||||
* All descriptions of options in --help should start in the
|
||||
same column (but it doesn't need to be the same column as
|
||||
in the English messages; just be consistent if you change it).
|
||||
Check that both --help and --long-help look OK, since they
|
||||
share several strings.
|
||||
|
||||
* --list --verbose and --info-memory print lines that have
|
||||
the format "Description: %s". If you need a longer
|
||||
description, you can put extra space between the colon
|
||||
and %s. Then you may need to add extra space to other
|
||||
strings too so that the result as a whole looks good (all
|
||||
values start at the same column).
|
||||
|
||||
* The columns of the actual tables in --list --verbose --verbose
|
||||
should be aligned properly. Abbreviate if necessary. It might
|
||||
be good to keep at least 2 or 3 spaces between column headings
|
||||
and avoid spaces in the headings so that the columns stand out
|
||||
better, but this is a matter of opinion. Do what you think
|
||||
looks best.
|
||||
|
||||
- Be careful to put a period at the end of a sentence when the
|
||||
original version has it, and don't put it when the original
|
||||
doesn't have it. Similarly, be careful with \n characters
|
||||
at the beginning and end of the strings.
|
||||
|
||||
- Read the TRANSLATORS comments that have been extracted from the
|
||||
source code and included in xz.pot. If they suggest testing the
|
||||
translation with some type of command, do it. If testing needs
|
||||
input files, use e.g. tests/files/good-*.xz.
|
||||
|
||||
- When updating the translation, read the fuzzy (modified) strings
|
||||
carefully, and don't mark them as updated before you actually
|
||||
have updated them. Reading through the unchanged messages can be
|
||||
good too; sometimes you may find a better wording for them.
|
||||
|
||||
- If you find language problems in the original English strings,
|
||||
feel free to suggest improvements. Ask if something is unclear.
|
||||
|
||||
- The translated messages should be understandable (sometimes this
|
||||
may be a problem with the original English messages too). Don't
|
||||
make a direct word-by-word translation from English especially if
|
||||
the result doesn't sound good in your language.
|
||||
|
||||
In short, take your time and pay attention to the details. Making
|
||||
a good translation is not a quick and trivial thing to do. The
|
||||
translated xz should look as polished as the English version.
|
||||
|
||||
|
||||
5. Other implementations of the .xz format
|
||||
------------------------------------------
|
||||
|
||||
7-Zip and the p7zip port of 7-Zip support the .xz format starting
|
||||
from the version 9.00alpha.
|
||||
|
||||
http://7-zip.org/
|
||||
http://p7zip.sourceforge.net/
|
||||
|
||||
XZ Embedded is a limited implementation written for use in the Linux
|
||||
kernel, but it is also suitable for other embedded use.

||||

||||

|
||||
|
||||
|
||||
6. Contact information
|
||||
----------------------
|
||||
|
||||
If you have questions, bug reports, patches etc. related to XZ Utils,
|
||||
contact Lasse Collin <lasse.collin@tukaani.org> (in Finnish or English).
|
||||
I'm sometimes slow at replying. If you haven't got a reply within two
|
||||
weeks, assume that your email has got lost and resend it or use IRC.
|
||||
|
||||
You can find me also from #tukaani on Freenode; my nick is Larhzu.
|
||||
The channel tends to be pretty quiet, so just ask your question and
|
||||
someone may wake up.

XZ Utils To-Do List
|
||||
===================
|
||||
|
||||
Known bugs
|
||||
----------
|
||||
|
||||
The test suite is too incomplete.
|
||||
|
||||
If the memory usage limit is less than about 13 MiB, xz is unable to
|
||||
automatically scale down the compression settings enough even though
|
||||
it would be possible by switching from BT2/BT3/BT4 match finder to
|
||||
HC3/HC4.
|
||||
|
||||
XZ Utils compress some files significantly worse than LZMA Utils.
|
||||
This is due to faster compression presets used by XZ Utils, and
|
||||
can often be worked around by using "xz --extreme". With some files
|
||||
--extreme isn't enough though: it's most likely with files that
|
||||
compress extremely well, so going from compression ratio of 0.003
|
||||
to 0.004 means big relative increase in the compressed file size.
|
||||
|
||||
xz doesn't quote unprintable characters when it displays file names
|
||||
given on the command line.
|
||||
|
||||
tuklib_exit() doesn't block signals => EINTR is possible.
|
||||
|
||||
SIGTSTP is not handled. If xz is stopped, the estimated remaining
|
||||
time and calculated (de)compression speed won't make sense in the
|
||||
progress indicator (xz --verbose).
|
||||
|
||||
If liblzma has created threads and fork() gets called, liblzma
|
||||
code will break in the child process unless it calls exec() and
|
||||
doesn't touch liblzma.
|
||||
|
||||
|
||||
Missing features
|
||||
----------------
|
||||
|
||||
Add support for storing metadata in .xz files. A preliminary
|
||||
idea is to create a new Stream type for metadata. When both
|
||||
metadata and data are wanted in the same .xz file, two or more
|
||||
Streams would be concatenated.
|
||||
|
||||
The state stored in lzma_stream should be cloneable, which would
|
||||
be mostly useful when using a preset dictionary in LZMA2, but
|
||||
it may have other uses too. Compare to deflateCopy() in zlib.
|
||||
|
||||
Support LZMA_FINISH in raw decoder to indicate end of LZMA1 and
|
||||
other streams that don't have an end of payload marker.
|
||||
|
||||
Adjust dictionary size when the input file size is known.
|
||||
Maybe do this only if an option is given.
|
||||
|
||||
xz doesn't support copying extended attributes, access control
|
||||
lists etc. from source to target file.
|
||||
|
||||
Multithreaded compression:
|
||||
- Reduce memory usage of the current method.
|
||||
- Implement threaded match finders.
|
||||
- Implement pigz-style threading in LZMA2.
|
||||
|
||||
Multithreaded decompression
|
||||
|
||||
Buffer-to-buffer coding could use less RAM (especially when
|
||||
decompressing LZMA1 or LZMA2).
|
||||
|
||||
I/O library is not implemented (similar to gzopen() in zlib).
|
||||
It will be a separate library that supports uncompressed, .gz,
|
||||
.bz2, .lzma, and .xz files.
|
||||
|
||||
Support changing lzma_options_lzma.mode with lzma_filters_update().
|
||||
|
||||
Support LZMA_FULL_FLUSH for lzma_stream_decoder() to stop at
|
||||
Block and Stream boundaries.
|
||||
|
||||
lzma_strerror() to convert lzma_ret to human readable form?
|
||||
This is tricky, because the same error codes are used with
|
||||
slightly different meanings, and this cannot be fixed anymore.
|
||||
|
||||
Make it possible to adjust LZMA2 options in the middle of a Block
|
||||
so that the encoding speed vs. compression ratio can be optimized
|
||||
when the compressed data is streamed over network.
|
||||
|
||||
Improved BCJ filters. The current filters are small but they aren't
|
||||
so great when compressing binary packages that contain various file
|
||||
types. Specifically, they make things worse if there are static
|
||||
libraries or Linux kernel modules. The filtering could also be
|
||||
more effective (without getting overly complex), for example,
|
||||
streamable variant BCJ2 from 7-Zip could be implemented.
|
||||
|
||||
Filter that autodetects specific data types in the input stream
|
||||
and applies appropriate filters for the corrects parts of the input.
|
||||
Perhaps combine this with the BCJ filter improvement point above.
|
||||
|
||||
Long-range LZ77 method as a separate filter or as a new LZMA2
|
||||
match finder.
|
||||
|
||||
|
||||
Documentation
|
||||
-------------
|
||||
|
||||
More tutorial programs are needed for liblzma.
|
||||
|
||||
Document the LZMA1 and LZMA2 algorithms.
|
||||
|
||||
|
||||
Miscellaneous
|
||||
------------
|
||||
|
||||
Try to get the media type for .xz registered at IANA.

## (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). Also, it might not be
|
||||
## supported by the other compilers which use the 'gcc' depmode.

## 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.
|
||||
## Some versions of gcc put a space before the ':'. On the theory
|
||||
## that the space means something, we add a space to the output as
|
||||
## well. hp depmode also adds that space, but also prefixes the VPATH
|
||||
## to the object. Take care to not repeat it in the output.

Debug tools
|
||||
-----------
|
||||
|
||||
This directory contains a few tiny programs that may be helpful when
|
||||
debugging XZ Utils.
|
||||
|
||||
These tools are not meant to be installed. Often one needs to edit
|
||||
the source code a little to make the programs do the wanted things.
|
||||
If you don't know how these programs could help you, it is likely
|
||||
that they really are useless to you.
|
||||
|
||||
These aren't intended to be used as example programs. They take some
|
||||
shortcuts here and there, which correct programs should not do. Many
|
||||
possible errors (especially I/O errors) are ignored. Don't report
|
||||
bugs or send patches to fix this kind of bugs.

liblzma example programs

========================

|
||||
Introduction
|
||||
|
||||
The examples are written so that the same comments aren't
|
||||
repeated (much) in later files.
|
||||
|
||||
On POSIX systems, the examples should build by just typing "make".
|
||||
|
||||
The examples that use stdin or stdout don't set stdin and stdout
|
||||
to binary mode. On systems where it matters (e.g. Windows) it is
|
||||
possible that the examples won't work without modification.
|
||||

XZ Utils FAQ
|
||||
============
|
||||
|
||||
Q: What do the letters XZ mean?
|
||||
|
||||
A: Nothing. They are just two letters, which come from the file format
|
||||
suffix .xz. The .xz suffix was selected, because it seemed to be
|
||||
pretty much unused. It has no deeper meaning.
|
||||
|
||||
|
||||
Q: What are LZMA and LZMA2?
|
||||
|
||||
A: LZMA stands for Lempel-Ziv-Markov chain-Algorithm. It is the name
|
||||
of the compression algorithm designed by Igor Pavlov for 7-Zip.
|
||||
LZMA is based on LZ77 and range encoding.
|
||||
|
||||
LZMA2 is an updated version of the original LZMA to fix a couple of
|
||||
practical issues. In context of XZ Utils, LZMA is called LZMA1 to
|
||||
emphasize that LZMA is not the same thing as LZMA2. LZMA2 is the
|
||||
primary compression algorithm in the .xz file format.
|
||||
|
||||
|
||||
Q: There are many LZMA related projects. How does XZ Utils relate to them?
|
||||
|
||||
A: 7-Zip and LZMA SDK are the original projects. LZMA SDK is roughly
|
||||
a subset of the 7-Zip source tree.
|
||||
|
||||
p7zip is 7-Zip's command-line tools ported to POSIX-like systems.
|
||||
|
||||
LZMA Utils provide a gzip-like lzma tool for POSIX-like systems.
|
||||
LZMA Utils are based on LZMA SDK. XZ Utils are the successor to
|
||||
LZMA Utils.
|
||||
|
||||
There are several other projects using LZMA. Most are more or less
|
||||
based on LZMA SDK. See <http://7-zip.org/links.html>.
|
||||
|
||||
|
||||
Q: Why is liblzma named liblzma if its primary file format is .xz?
|
||||
Shouldn't it be e.g. libxz?
|
||||
|
||||
A: When the designing of the .xz format began, the idea was to replace
|
||||
the .lzma format and use the same .lzma suffix. It would have been
|
||||
quite OK to reuse the suffix when there were very few .lzma files
|
||||
around. However, the old .lzma format became popular before the
|
||||
new format was finished. The new format was renamed to .xz but the
|
||||
name of liblzma wasn't changed.
|
||||
|
||||
|
||||
Q: Do XZ Utils support the .7z format?
|
||||
|
||||
A: No. Use 7-Zip (Windows) or p7zip (POSIX-like systems) to handle .7z
|
||||
files.
|
||||
|
||||
|
||||
Q: I have many .tar.7z files. Can I convert them to .tar.xz without
|
||||
spending hours recompressing the data?
|
||||
|
||||
A: In the "extra" directory, there is a script named 7z2lzma.bash which
|
||||
is able to convert some .7z files to the .lzma format (not .xz). It
|
||||
needs the 7za (or 7z) command from p7zip. The script may silently
|
||||
produce corrupt output if certain assumptions are not met, so
|
||||
decompress the resulting .lzma file and compare it against the
|
||||
original before deleting the original file!
|
||||
|
||||
|
||||
Q: I have many .lzma files. Can I quickly convert them to the .xz format?
|
||||
|
||||
A: For now, no. Since XZ Utils supports the .lzma format, it's usually
|
||||
not too bad to keep the old files in the old format. If you want to
|
||||
do the conversion anyway, you need to decompress the .lzma files and
|
||||
then recompress to the .xz format.
|
||||
|
||||
Technically, there is a way to make the conversion relatively fast
|
||||
(roughly twice the time that normal decompression takes). Writing
|
||||
such a tool would take quite a bit of time though, and would probably
|
||||
be useful to only a few people. If you really want such a conversion
|
||||
tool, contact Lasse Collin and offer some money.
|
||||
|
||||
|
||||
Q: I have installed xz, but my tar doesn't recognize .tar.xz files.
|
||||
How can I extract .tar.xz files?
|
||||
|
||||
A: xz -dc foo.tar.xz | tar xf -
|
||||
|
||||
|
||||
Q: Can I recover parts of a broken .xz file (e.g. a corrupted CD-R)?
|
||||
|
||||
A: It may be possible if the file consists of multiple blocks, which
|
||||
typically is not the case if the file was created in single-threaded
|
||||
mode. There is no recovery program yet.
|
||||
|
||||
|
||||
Q: Is (some part of) XZ Utils patented?
|
||||
|
||||
A: Lasse Collin is not aware of any patents that could affect XZ Utils.
|
||||
However, due to the nature of software patents, it's not possible to
|
||||
guarantee that XZ Utils isn't affected by any third party patent(s).
|
||||
|
||||
|
||||
Q: Where can I find documentation about the file format and algorithms?
|
||||
|
||||
A: The .xz format is documented in xz-file-format.txt. It is a container
|
||||
format only, and doesn't include descriptions of any non-trivial
|
||||
filters.
|
||||
|
||||
Documenting LZMA and LZMA2 is planned, but for now, there is no other
|
||||
documentation than the source code. Before you begin, you should know
|
||||
the basics of LZ77 and range-coding algorithms. LZMA is based on LZ77,
|
||||
but LZMA is a lot more complex. Range coding is used to compress
|
||||
the final bitstream like Huffman coding is used in Deflate.
|
||||
|
||||
|
||||
Q: I cannot find BCJ and BCJ2 filters. Don't they exist in liblzma?
|
||||
|
||||
A: BCJ filter is called "x86" in liblzma. BCJ2 is not included,
|
||||
because it requires using more than one encoded output stream.
|
||||
A streamable version of BCJ2-style filtering is planned.
|
||||
|
||||
|
||||
Q: I need to use a script that runs "xz -9". On a system with 256 MiB
|
||||
of RAM, xz says that it cannot allocate memory. Can I make the
|
||||
script work without modifying it?
|
||||
|
||||
A: Set a default memory usage limit for compression. You can do it e.g.
|
||||
in a shell initialization script such as ~/.bashrc or /etc/profile:
|
||||
|
||||
XZ_DEFAULTS=--memlimit-compress=150MiB
|
||||
export XZ_DEFAULTS
|
||||
|
||||
xz will then scale the compression settings down so that the given
|
||||
memory usage limit is not reached. This way xz shouldn't run out
|
||||
of memory.
|
||||
|
||||
Check also that memory-related resource limits are high enough.
|
||||
On most systems, "ulimit -a" will show the current resource limits.
|
||||
|
||||
|
||||
Q: How do I create files that can be decompressed with XZ Embedded?
|
||||
|
||||
A: See the documentation in XZ Embedded. In short, something like
|
||||
this is a good start:
|
||||
|
||||
xz --check=crc32 --lzma2=preset=6e,dict=64KiB
|
||||
|
||||
Or if a BCJ filter is needed too, e.g. if compressing
|
||||
a kernel image for PowerPC:
|
||||
|
||||
xz --check=crc32 --powerpc --lzma2=preset=6e,dict=64KiB
|
||||
|
||||
Adjust the dictionary size to get a good compromise between
|
||||
compression ratio and decompressor memory usage. Note that
|
||||
in single-call decompression mode of XZ Embedded, a big
|
||||
dictionary doesn't increase memory usage.
|
||||
|
||||
|
||||
Q: Will xz support threaded compression?
|
||||
|
||||
A: It is planned and has been taken into account when designing
|
||||
the .xz file format. Eventually there will probably be three types
|
||||
of threading, each method having its own advantages and disadvantages.
|
||||
|
||||
The simplest method is splitting the uncompressed data into blocks
|
||||
and compressing them in parallel independent from each other.
|
||||
Since the blocks are compressed independently, they can also be
|
||||
decompressed independently. Together with the index feature in .xz,
|
||||
this allows using threads to create .xz files for random-access
|
||||
reading. This also makes threaded decompression possible, although
|
||||
it is not clear if threaded decompression will ever be implemented.
|
||||
|
||||
The independent blocks method has a couple of disadvantages too. It
|
||||
will compress worse than a single-block method. Often the difference
|
||||
is not too big (maybe 1-2 %) but sometimes it can be too big. Also,
|
||||
the memory usage of the compressor increases linearly when adding
|
||||
threads.
|
||||
|
||||
Match finder parallelization is another threading method. It has
|
||||
been in 7-Zip for ages. It doesn't affect compression ratio or
|
||||
memory usage significantly. Among the three threading methods, only
|
||||
this is useful when compressing small files (files that are not
|
||||
significantly bigger than the dictionary). Unfortunately this method
|
||||
scales only to about two CPU cores.
|
||||
|
||||
The third method is pigz-style threading (I use that name, because
|
||||
pigz <http://www.zlib.net/pigz/> uses that method). It doesn't
|
||||
affect compression ratio significantly and scales to many cores.
|
||||
The memory usage scales linearly when threads are added. This isn't
|
||||
significant with pigz, because Deflate uses only a 32 KiB dictionary,
|
||||
but with LZMA2 the memory usage will increase dramatically just like
|
||||
with the independent-blocks method. There is also a constant
|
||||
computational overhead, which may make pigz-method a bit dull on
|
||||
dual-core compared to the parallel match finder method, but with more
|
||||
cores the overhead is not a big deal anymore.
|
||||
|
||||
Combining the threading methods will be possible and also useful.
|
||||
E.g. combining match finder parallelization with pigz-style threading
|
||||
can cut the memory usage by 50 %.
|
||||
|
||||
It is possible that the single-threaded method will be modified to
|
||||
create files identical to the pigz-style method. We'll see once
|
||||
pigz-style threading has been implemented in liblzma.
|
||||
|
||||
|
||||
Q: How do I build a program that needs liblzmadec (lzmadec.h)?
|
||||
|
||||
A: liblzmadec is part of LZMA Utils. XZ Utils has liblzma, but no
|
||||
liblzmadec. The code using liblzmadec should be ported to use
|
||||
liblzma instead. If you cannot or don't want to do that, download
|
||||
LZMA Utils from <http://tukaani.org/lzma/>.
|
||||
|
||||
|
||||
Q: The default build of liblzma is too big. How can I make it smaller?
|
||||
|
||||
A: Give --enable-small to the configure script. Use also appropriate
|
||||
--enable or --disable options to include only those filter encoders
|
||||
and decoders and integrity checks that you actually need. Use
|
||||
CFLAGS=-Os (with GCC) or equivalent to tell your compiler to optimize
|
||||
for size. See INSTALL for information about configure options.
|
||||
|
||||
If the result is still too big, take a look at XZ Embedded. It is
|
||||
a separate project, which provides a limited but significantly
|
||||
smaller XZ decoder implementation than XZ Utils. You can find it
|
||||
at <http://tukaani.org/xz/embedded.html>.

History of LZMA Utils and XZ Utils
|
||||
==================================
|
||||
|
||||
Tukaani distribution
|
||||
|
||||
In 2005, there was a small group working on the Tukaani distribution,
|
||||
which was a Slackware fork. One of the project's goals was to fit the
|
||||
distro on a single 700 MiB ISO-9660 image. Using LZMA instead of gzip
|
||||
helped a lot. Roughly speaking, one could fit data that took 1000 MiB
|
||||
in gzipped form into 700 MiB with LZMA. Naturally, the compression
|
||||
ratio varied across packages, but this was what we got on average.
|
||||
|
||||
Slackware packages have traditionally had .tgz as the filename suffix,
|
||||
which is an abbreviation of .tar.gz. A logical naming for LZMA
|
||||
compressed packages was .tlz, being an abbreviation of .tar.lzma.
|
||||
|
||||
At the end of the year 2007, there was no distribution under the
|
||||
Tukaani project anymore, but development of LZMA Utils was kept going.
|
||||
Still, there were .tlz packages around, because at least Vector Linux
|
||||
(a Slackware based distribution) used LZMA for its packages.
|
||||
|
||||
First versions of the modified pkgtools used the LZMA_Alone tool from
|
||||
Igor Pavlov's LZMA SDK as is. It was fine, because users wouldn't need
|
||||
to interact with LZMA_Alone directly. But people soon wanted to use
|
||||
LZMA for other files too, and the interface of LZMA_Alone wasn't
|
||||
comfortable for those used to gzip and bzip2.
|
||||
|
||||
|
||||
First steps of LZMA Utils
|
||||
|
||||
The first version of LZMA Utils (4.22.0) included a shell script called
|
||||
lzmash. It was a wrapper that had a gzip-like command-line interface. It
|
||||
used the LZMA_Alone tool from LZMA SDK to do all the real work. zgrep,
|
||||
zdiff, and related scripts from gzip were adapted to work with LZMA and
|
||||
were part of the first LZMA Utils release too.
|
||||
|
||||
LZMA Utils 4.22.0 included also lzmadec, which was a small (less than
|
||||
10 KiB) decoder-only command-line tool. It was written on top of the
|
||||
decoder-only C code found from the LZMA SDK. lzmadec was convenient in
|
||||
situations where LZMA_Alone (a few hundred KiB) would be too big.
|
||||
|
||||
lzmash and lzmadec were written by Lasse Collin.
|
||||
|
||||
|
||||
Second generation
|
||||
|
||||
The lzmash script was an ugly and not very secure hack. The last
|
||||
version of LZMA Utils to use lzmash was 4.27.1.
|
||||
|
||||
LZMA Utils 4.32.0beta1 introduced a new lzma command-line tool written
|
||||
by Ville Koskinen. It was written in C++, and used the encoder and
|
||||
decoder from C++ LZMA SDK with some little modifications. This tool
|
||||
replaced both the lzmash script and the LZMA_Alone command-line tool
|
||||
in LZMA Utils.
|
||||
|
||||
Introducing this new tool caused some temporary incompatibilities,
|
||||
because the LZMA_Alone executable was simply named lzma like the new
|
||||
command-line tool, but they had a completely different command-line
|
||||
interface. The file format was still the same.
|
||||
|
||||
Lasse wrote liblzmadec, which was a small decoder-only library based
|
||||
on the C code found from LZMA SDK. liblzmadec had an API similar to
|
||||
zlib, although there were some significant differences, which made it
|
||||
non-trivial to use it in some applications designed for zlib and
|
||||
libbzip2.
|
||||
|
||||
The lzmadec command-line tool was converted to use liblzmadec.
|
||||
|
||||
Alexandre Sauvé helped converting the build system to use GNU
|
||||
Autotools. This made it easier to test for certain less portable
|
||||
features needed by the new command-line tool.
|
||||
|
||||
Since the new command-line tool never got completely finished (for
|
||||
example, it didn't support the LZMA_OPT environment variable), the
|
||||
intent was to not call 4.32.x stable. Similarly, liblzmadec wasn't
|
||||
polished, but appeared to work well enough, so some people started
|
||||
using it too.
|
||||
|
||||
Because the development of the third generation of LZMA Utils was
|
||||
delayed considerably (3-4 years), the 4.32.x branch had to be kept
|
||||
maintained. It got some bug fixes now and then, and finally it was
|
||||
decided to call it stable, although most of the missing features were
|
||||
never added.
|
||||
|
||||
|
||||
File format problems
|
||||
|
||||
The file format used by LZMA_Alone was primitive. It was designed with
|
||||
embedded systems in mind, and thus provided only a minimal set of
|
||||
features. The two biggest problems for non-embedded use were the lack
|
||||
of magic bytes and an integrity check.
|
||||
|
||||
Igor and Lasse started developing a new file format with some help
|
||||
from Ville Koskinen. Also Mark Adler, Mikko Pouru, H. Peter Anvin,
|
||||
and Lars Wirzenius helped with some minor things at some point of the
|
||||
development. Designing the new format took quite a long time (actually,
|
||||
too long a time would be a more appropriate expression). It was mostly
|
||||
because Lasse was quite slow at getting things done due to personal
|
||||
reasons.
|
||||
|
||||
Originally the new format was supposed to use the same .lzma suffix
|
||||
that was already used by the old file format. Switching to the new
|
||||
format wouldn't have caused much trouble when the old format wasn't
|
||||
used by many people. But since the development of the new format took
|
||||
such a long time, the old format got quite popular, and it was decided
|
||||
that the new file format must use a different suffix.
|
||||
|
||||
It was decided to use .xz as the suffix of the new file format. The
|
||||
first stable .xz file format specification was finally released in
|
||||
December 2008. In addition to fixing the most obvious problems of
|
||||
the old .lzma format, the .xz format added some new features like
|
||||
support for multiple filters (compression algorithms), filter chaining
|
||||
(like piping on the command line), and limited random-access reading.
|
||||
|
||||
Currently the primary compression algorithm used in .xz is LZMA2.
|
||||
It is an extension on top of the original LZMA to fix some practical
|
||||
problems: LZMA2 adds support for flushing the encoder, uncompressed
|
||||
chunks, eases stateful decoder implementations, and improves support
|
||||
for multithreading. Since LZMA2 is better than the original LZMA, the
|
||||
original LZMA is not supported in .xz.
|
||||
|
||||
|
||||
Transition to XZ Utils
|
||||
|
||||
The early versions of XZ Utils were called LZMA Utils. The first
|
||||
releases were 4.42.0alphas. They dropped the rest of the C++ LZMA SDK.
|
||||
The code was still directly based on LZMA SDK but ported to C and
|
||||
converted from a callback API to a stateful API. Later, Igor Pavlov
|
||||
made a C version of the LZMA encoder too; these ports from C++ to C
|
||||
were independent in LZMA SDK and LZMA Utils.
|
||||
|
||||
The core of the new LZMA Utils was liblzma, a compression library with
|
||||
a zlib-like API. liblzma supported both the old and new file format.
|
||||
The gzip-like lzma command-line tool was rewritten to use liblzma.
|
||||
|
||||
The new LZMA Utils code base was renamed to XZ Utils when the name
|
||||
of the new file format had been decided. The liblzma compression
|
||||
library retained its name though, because changing it would have
|
||||
caused unnecessary breakage in applications already using the early
|
||||
liblzma snapshots.
|
||||
|
||||
The xz command-line tool can emulate the gzip-like lzma tool by
|
||||
creating appropriate symlinks (e.g. lzma -> xz). Thus, practically
|
||||
all scripts using the lzma tool from LZMA Utils will work as is with
|
||||
XZ Utils (and will keep using the old .lzma format). Still, the .lzma
|
||||
format is more or less deprecated. XZ Utils will keep supporting it,
|
||||
but new applications should use the .xz format, and migrating old
|
||||
applications to .xz is often a good idea too.

0. Preface
|
||||
|
||||
This document describes the .lzma file format, which is
|
||||
sometimes also called LZMA_Alone format. It is a legacy file
|
||||
format, which is being or has been replaced by the .xz format.
|
||||
The MIME type of the .lzma format is `application/x-lzma'.
|
||||
|
||||
The most commonly used software to handle .lzma files are
|
||||
LZMA SDK, LZMA Utils, 7-Zip, and XZ Utils. This document
|
||||
describes some of the differences between these implementations
|
||||
and gives hints what subset of the .lzma format is the most
|
||||
portable.

|

|

The .lzma format file consist of 13-byte Header followed by
|
||||
the LZMA Compressed Data.
|
||||
|
||||
Unlike the .gz, .bz2, and .xz formats, it is not possible to
|
||||
concatenate multiple .lzma files as is and expect the
|
||||
decompression tool to decode the resulting file as if it were
|
||||
a single .lzma file.
|
||||
|
||||
For example, the command line tools from LZMA Utils and
|
||||
LZMA SDK silently ignore all the data after the first .lzma
|
||||
stream. In contrast, the command line tool from XZ Utils
|
||||
considers the .lzma file to be corrupt if there is data after
|
||||
the first .lzma stream.

|
||||
|
||||
|
||||
1.1.1. Properties
|
||||
|
||||
The Properties field contains three properties. An abbreviation
|
||||
is given in parentheses, followed by the value range of the
|
||||
property. The field consists of
|
||||
|
||||
1) the number of literal context bits (lc, [0, 8]);
|
||||
2) the number of literal position bits (lp, [0, 4]); and
|
||||
3) the number of position bits (pb, [0, 4]).
|
||||
|
||||
The properties are encoded using the following formula:
|
||||
|
||||
Properties = (pb * 5 + lp) * 9 + lc
|
||||
|
||||
The following C code illustrates a straightforward way to
|
||||
decode the Properties field:
|
||||
|
||||
uint8_t lc, lp, pb;
|
||||
uint8_t prop = get_lzma_properties();
|
||||
if (prop > (4 * 5 + 4) * 9 + 8)
|
||||
return LZMA_PROPERTIES_ERROR;
|
||||
|
||||
pb = prop / (9 * 5);
|
||||
prop -= pb * 9 * 5;
|
||||
lp = prop / 9;
|
||||
lc = prop - lp * 9;
|
||||
|
||||
XZ Utils has an additional requirement: lc + lp <= 4. Files
|
||||
which don't follow this requirement cannot be decompressed
|
||||
with XZ Utils. Usually this isn't a problem since the most
|
||||
common lc/lp/pb values are 3/0/2. It is the only lc/lp/pb
|
||||
combination that the files created by LZMA Utils can have,
|
||||
but LZMA Utils can decompress files with any lc/lp/pb.
|
||||
|
||||
|
||||
1.1.2. Dictionary Size
|
||||
|
||||
Dictionary Size is stored as an unsigned 32-bit little endian
|
||||
integer. Any 32-bit value is possible, but for maximum
|
||||
portability, only sizes of 2^n and 2^n + 2^(n-1) should be
|
||||
used.
|
||||
|
||||
LZMA Utils creates only files with dictionary size 2^n,
|
||||
16 <= n <= 25. LZMA Utils can decompress files with any
|
||||
dictionary size.
|
||||
|
||||
XZ Utils creates and decompresses .lzma files only with
|
||||
dictionary sizes 2^n and 2^n + 2^(n-1). If some other
|
||||
dictionary size is specified when compressing, the value
|
||||
stored in the Dictionary Size field is a rounded up, but the
|
||||
specified value is still used in the actual compression code.
|
||||
|
||||
|
||||
1.1.3. Uncompressed Size
|
||||
|
||||
Uncompressed Size is stored as unsigned 64-bit little endian
|
||||
integer. A special value of 0xFFFF_FFFF_FFFF_FFFF indicates
|
||||
that Uncompressed Size is unknown. End of Payload Marker (*)
|
||||
is used if and only if Uncompressed Size is unknown.
|
||||
|
||||
XZ Utils rejects files whose Uncompressed Size field specifies
|
||||
a known size that is 256 GiB or more. This is to reject false
|
||||
positives when trying to guess if the input file is in the
|
||||
.lzma format. When Uncompressed Size is unknown, there is no
|
||||
limit for the uncompressed size of the file.
|
||||
|
||||
(*) Some tools use the term End of Stream (EOS) marker
|
||||
instead of End of Payload Marker.
|
||||
|
||||
|
||||
1.2. LZMA Compressed Data
|
||||
|
||||
Detailed description of the format of this field is out of
|
||||
scope of this document.

NAME
|
||||
lzmainfo - show information stored in the .lzma file header
|
||||
|
||||
SYNOPSIS
|
||||
lzmainfo [--help] [--version] [file...]
|
||||
|
||||
DESCRIPTION
|
||||
lzmainfo shows information stored in the .lzma file header. It reads
|
||||
the first 13 bytes from the specified file, decodes the header, and
|
||||
prints it to standard output in human readable format. If no files are
|
||||
given or file is -, standard input is read.
|
||||
|
||||
Usually the most interesting information is the uncompressed size and
|
||||
the dictionary size. Uncompressed size can be shown only if the file
|
||||
is in the non-streamed .lzma format variant. The amount of memory
|
||||
required to decompress the file is a few dozen kilobytes plus the dic-
|
||||
tionary size.
|
||||
|
||||
lzmainfo is included in XZ Utils primarily for backward compatibility
|
||||
with LZMA Utils.
|
||||
|
||||
EXIT STATUS

|
||||
BUGS
|
||||
lzmainfo uses MB while the correct suffix would be MiB (2^20 bytes).
|
||||
This is to keep the output compatible with LZMA Utils.

NAME
|
||||
xzdec, lzmadec - Small .xz and .lzma decompressors
|
||||
|
||||
SYNOPSIS
|
||||
xzdec [option...] [file...]
|
||||
lzmadec [option...] [file...]
|
||||
|
||||
DESCRIPTION
|
||||
xzdec is a liblzma-based decompression-only tool for .xz (and only .xz)
|
||||
files. xzdec is intended to work as a drop-in replacement for xz(1) in
|
||||
the most common situations where a script has been written to use xz
|
||||
--decompress --stdout (and possibly a few other commonly used options)
|
||||
to decompress .xz files. lzmadec is identical to xzdec except that
|
||||
lzmadec supports .lzma files instead of .xz files.
|
||||
|
||||
To reduce the size of the executable, xzdec doesn't support multi-
|
||||
threading or localization, and doesn't read options from XZ_DEFAULTS
|
||||
and XZ_OPT environment variables. xzdec doesn't support displaying
|
||||
intermediate progress information: sending SIGINFO to xzdec does noth-
|
||||
ing, but sending SIGUSR1 terminates the process instead of displaying
|
||||
progress information.
|
||||
|
||||
OPTIONS
|
||||
-d, --decompress, --uncompress
|
||||
Ignored for xz(1) compatibility. xzdec supports only decompres-
|
||||
sion.
|
||||
|
||||
-k, --keep
|
||||
Ignored for xz(1) compatibility. xzdec never creates or removes
|
||||
any files.
|
||||
|
||||
-c, --stdout, --to-stdout
|
||||
Ignored for xz(1) compatibility. xzdec always writes the decom-
|
||||
pressed data to standard output.
|
||||
|
||||
-q, --quiet
|
||||
Specifying this once does nothing since xzdec never displays any
|
||||
warnings or notices. Specify this twice to suppress errors.
|
||||
|
||||
-Q, --no-warn
|
||||
Ignored for xz(1) compatibility. xzdec never uses the exit sta-
|
||||
tus 2.
|
||||
|
||||
-h, --help
|
||||
Display a help message and exit successfully.
|
||||
|
||||
-V, --version
|
||||
Display the version number of xzdec and liblzma.
|
||||
|
||||
EXIT STATUS
|
||||
0 All was good.
|
||||
|
||||
1 An error occurred.
|
||||
|
||||
xzdec doesn't have any warning messages like xz(1) has, thus the exit
|
||||
status 2 is not used by xzdec.
|
||||
|
||||
NOTES
|
||||
Use xz(1) instead of xzdec or lzmadec for normal everyday use. xzdec
|
||||
or lzmadec are meant only for situations where it is important to have
|
||||
a smaller decompressor than the full-featured xz(1).
|
||||
|
||||
xzdec and lzmadec are not really that small. The size can be reduced
|
||||
further by dropping features from liblzma at compile time, but that
|
||||
shouldn't usually be done for executables distributed in typical non-
|
||||
embedded operating system distributions. If you need a truly small .xz
|
||||
decompressor, consider using XZ Embedded.

are passed directly to cmp(1) or diff(1). If only one file is speci-
|
||||
fied, then the files compared are file1 (which must have a suffix of a
|
||||
supported compression format) and file1 from which the compression for-
|
||||
mat suffix has been stripped. If two files are specified, then they
|
||||
are uncompressed if necessary and fed to cmp(1) or diff(1). The exit

NAME
|
||||
xzless, lzless - view xz or lzma compressed (text) files
|
||||
|
||||
SYNOPSIS
|
||||
xzless [file...]
|
||||
lzless [file...]
|
||||
|
||||
DESCRIPTION
|
||||
xzless is a filter that displays text from compressed files to a termi-
|
||||
nal. It works on files compressed with xz(1) or lzma(1). If no files
|
||||
are given, xzless reads from standard input.
|
||||
|
||||
xzless uses less(1) to present its output. Unlike xzmore, its choice
|
||||
of pager cannot be altered by setting an environment variable. Com-
|
||||
mands are based on both more(1) and vi(1) and allow back and forth
|
||||
movement and searching. See the less(1) manual for more information.
|
||||
|
||||
The command named lzless is provided for backward compatibility with
|
||||
LZMA Utils.
|
||||
|
||||
ENVIRONMENT
|
||||
LESSMETACHARS
|
||||
A list of characters special to the shell. Set by xzless unless
|
||||
it is already set in the environment.
|
||||
|
||||
LESSOPEN
|
||||
Set to a command line to invoke the xz(1) decompressor for pre-
|
||||
processing the input files to less(1).

SYNOPSIS

DESCRIPTION
|

xzmore is a filter which allows examination of xz(1) or lzma(1) com-
|
||||
pressed text files one screenful at a time on a soft-copy terminal.
|
||||
|
||||
To use a pager other than the default more, set environment variable
|
||||
PAGER to the name of the desired program. The name lzmore is provided
|
||||
for backward compatibility with LZMA Utils.
|
||||
|
||||
e or q When the prompt --More--(Next file: file) is printed, this com-
|
||||
mand causes xzmore to exit.
|
||||
|

s When the prompt --More--(Next file: file) is printed, this com-
|

mand causes xzmore to skip the next file and continue.
|

|
||||
For list of keyboard commands supported while actually viewing the con-
|

Building XZ Utils for DOS
|
||||
=========================
|
||||
|
||||
Introduction
|
||||
|
||||
This document explains how to build XZ Utils for DOS using DJGPP.
|
||||
The resulting binaries should run at least on various DOS versions
|
||||
and under Windows 95/98/98SE/ME, although the Windows version of
|
||||
XZ Utils is recommended under Windows 95 and later.
|
||||
|
||||
This is currently experimental and has got very little testing.
|
||||
|
||||
Note: Makefile and config.h are updated only now and then. This
|
||||
means that especially if you checked out a development version,
|
||||
building for DOS probably won't work without updating Makefile
|
||||
and config.h first.
|
||||
|
||||
|
||||
Getting and Installing DJGPP
|
||||
|
||||
You may use <http://www.delorie.com/djgpp/zip-picker.html> to help
|
||||
deciding what to download, but as of writing (2010-10-09) that may
|
||||
not be the most convenient way taking into account what components
|
||||
are actually required to build XZ Utils. However, using the
|
||||
zip-picker can still be worth doing to get nice short summary of
|
||||
installation instructions (they can be found from readme.1st too).
|
||||
|
||||
For a more manual method, first select a mirror from
|
||||
<http://www.delorie.com/djgpp/getting.html>. You need
|
||||
the following files:
|
||||
|
||||
unzip32.exe (if you don't already have a LFN-capable unzipper)
|
||||
beta/v2/djdev204.zip
|
||||
v2gnu/bnu219b.zip
|
||||
v2gnu/gcc444b.zip
|
||||
v2gnu/mak3791b.zip
|
||||
v2misc/csdpmi7b.zip
|
||||
|
||||
If newer versions are available, probably you should try them first.
|
||||
Note that djdev203.zip is too old to build XZ Utils; you need at
|
||||
least djdev204.zip. Also note that you want csdpmi7b.zip even if you
|
||||
run under Windows or DOSEMU, because the XZ Utils Makefile will embed
|
||||
cwsdstub.exe to the resulting binaries.
|
||||
|
||||
See the instructions in readme.1st found from djdev204.zip. Here's
|
||||
a short summary, but you should still read readme.1st.
|
||||
|
||||
C:\> mkdir DJGPP
|
||||
C:\> cd DJGPP
|
||||
C:\DJGPP> c:\download\unzip32 c:\download\djdev204.zip
|
||||
C:\DJGPP> c:\download\unzip32 c:\download\bnu219b.zip
|
||||
C:\DJGPP> c:\download\unzip32 c:\download\gcc444b.zip
|
||||
C:\DJGPP> c:\download\unzip32 c:\download\mak3791b.zip
|
||||
C:\DJGPP> c:\download\unzip32 c:\download\csdpmi7b.zip
|
||||
|
||||
C:\DJGPP> set PATH=C:\DJGPP\BIN;%PATH%
|
||||
C:\DJGPP> set DJGPP=C:\DJGPP\DJGPP.ENV
|
||||
|
||||
You may want to add the last two lines into AUTOEXEC.BAT or have,
|
||||
for example, DJGPP.BAT which you can run before using DJGPP.
|
||||
|
||||
Make sure you use completely upper case path in the DJGPP environment
|
||||
variable. This is not required by DJGPP, but the XZ Utils Makefile is
|
||||
a bit stupid and expects that everything in DJGPP environment variable
|
||||
is uppercase.
|
||||
|
||||
|
||||
Building
|
||||
|
||||
You need to have an environment that supports long filenames (LFN).
|
||||
Once you have built XZ Utils, the resulting binaries can be run
|
||||
without long filename support.
|
||||
|
||||
Run "make" in this directory (the directory containing this README).
|
||||
You should get xz.exe (and a bunch of temporary files). Other tools
|
||||
are not built. Having e.g. xzdec.exe doesn't save much space compared
|
||||
to xz.exe, because the DJGPP runtime makes the .exe quite big anyway.

XZ Utils on DOS
|
||||
===============
|
||||
|
||||
DOS-specific filename handling
|
||||
|
||||
xz detects at runtime if long filename (LFN) support is
|
||||
available and will use it by default. It can be disabled by
|
||||
setting an environment variable:
|
||||
|
||||
set lfn=n
|
||||
|
||||
When xz is in LFN mode, it behaves pretty much the same as it
|
||||
does on other operating systems. Examples:
|
||||
|
||||
xz foo.tar -> foo.tar.xz
|
||||
xz -d foo.tar.xz -> foo.tar
|
||||
|
||||
xz -F lzma foo.tar -> foo.tar.lzma
|
||||
xz -d foo.tar.lzma -> foo.tar
|
||||
|
||||
When LFN support isn't available or it is disabled with LFN=n
|
||||
environment setting, xz works in short filename (SFN) mode. This
|
||||
affects filename suffix handling when compressing.
|
||||
|
||||
When compressing to the .xz format in SFN mode:
|
||||
|
||||
- Files without an extension get .xz just like on LFN systems.
|
||||
|
||||
- *.tar files become *.txz (shorthand for *.tar.xz). *.txz
|
||||
is recognized by xz on all supported operating systems.
|
||||
(Try to avoid confusing this with gzipped .txt files.)
|
||||
|
||||
- Files with 1-3 character extension have their extension modified
|
||||
so that the last character is a dash ("-"). If the extension
|
||||
is already three characters, the last character is lost. The
|
||||
resulting *.?- or *.??- filename is recognized in LFN mode, but
|
||||
it isn't recognized by xz on other operating systems.
|
||||
|
||||
Examples:
|
||||
|
||||
xz foo -> foo.xz | xz -d foo.xz -> foo
|
||||
xz foo.tar -> foo.txz | xz -d foo.txz -> foo.tar
|
||||
xz foo.c -> foo.c- | xz -d foo.c- -> foo.c
|
||||
xz read.me -> read.me- | xz -d read.me- -> read.me
|
||||
xz foo.txt -> foo.tx- | xz -d foo.tx- -> foo.tx !
|
||||
|
||||
Note that in the last example above, the third character of the
|
||||
filename extension is lost.
|
||||
|
||||
When compressing to the legacy .lzma format in SFN mode:
|
||||
|
||||
- *.tar files become *.tlz (shorthand for *.tar.lzma). *.tlz
|
||||
is recognized by xz on all supported operating systems.
|
||||
|
||||
- Other files become *.lzm. The original filename extension
|
||||
is lost. *.lzm is recognized also in LFN mode, but it is not
|
||||
recognized by xz on other operating systems.
|
||||
|
||||
Examples:
|
||||
|
||||
xz -F lzma foo -> foo.lzm | xz -d foo.lzm -> foo
|
||||
xz -F lzma foo.tar -> foo.tlz | xz -d foo.tlz -> foo.tar
|
||||
xz -F lzma foo.c -> foo.lzm | xz -d foo.lzm -> foo !
|
||||
xz -F lzma read.me -> read.lzm | xz -d read.lzm -> read !
|
||||
xz -F lzma foo.txt -> foo.lzm | xz -d foo.lzm -> foo !
|
||||
|
||||
When compressing with a custom suffix (-S .SUF, --suffix=.SUF) to
|
||||
any file format:
|
||||
|
||||
- If the suffix begins with a dot, the filename extension is
|
||||
replaced with the new suffix. The original extension is lost.
|
||||
|
||||
- If the suffix doesn't begin with a dot and the filename has no
|
||||
extension and the filename given on the command line doesn't
|
||||
have a dot at the end, the custom suffix is appended just like
|
||||
on LFN systems.
|
||||
|
||||
- If the suffix doesn't begin with a dot and the filename has
|
||||
an extension (or an extension-less filename is given with a dot
|
||||
at the end), the last 1-3 characters of the filename extension
|
||||
may get overwritten to fit the given custom suffix.
|
||||
|
||||
Examples:
|
||||
|
||||
xz -S x foo -> foox | xz -dS x foox -> foo
|
||||
xz -S x foo. -> foo.x | xz -dS x foo.x -> foo
|
||||
xz -S .x foo -> foo.x | xz -dS .x foo.x -> foo
|
||||
xz -S .x foo. -> foo.x | xz -dS .x foo.x -> foo
|
||||
xz -S x.y foo -> foox.y | xz -dS x.y foox.y -> foo
|
||||
xz -S .a foo.c -> foo.a | xz -dS .a foo.a -> foo !
|
||||
xz -S a foo.c -> foo.ca | xz -dS a foo.ca -> foo.c
|
||||
xz -S ab foo.c -> foo.cab | xz -dS ab foo.cab -> foo.c
|
||||
xz -S ab read.me -> read.mab | xz -dS ab read.mab -> read.m !
|
||||
xz -S ab foo.txt -> foo.tab | xz -dS ab foo.tab -> foo.t !
|
||||
xz -S abc foo.txt -> foo.abc | xz -dS abc foo.abc -> foo !
|
||||
|
||||
When decompressing, the suffix handling in SFN mode is the same as
|
||||
in LFN mode. The DOS-specific filenames *.lzm, *.?-, and *.??- are
|
||||
recognized also in LFN mode.
|
||||
|
||||
xz handles certain uncommon situations safely:
|
||||
|
||||
- If the generated output filename refers to the same file as
|
||||
the input file, xz detects this and refuses to compress or
|
||||
decompress the input file even if --force is used. This can
|
||||
happen when giving an overlong filename in SFN mode. E.g.
|
||||
"xz -S x foo.texinfo" would try to write to foo.tex which on
|
||||
SFN system is the same file as foo.texinfo.
|
||||
|
||||
- If the generated output filename is a special file like "con"
|
||||
or "prn", xz detects this and refuses to compress or decompress
|
||||
the input file even if --force is used.
|
||||
|
||||
|
||||
Bugs
|
||||
|
||||
xz doesn't necessarily work in Dosbox. It should work in DOSEMU.
|
||||
|
||||
Pressing Ctrl-c or Ctrl-Break won't remove the incomplete target file
|
||||
when running under Windows XP Command Prompt (something goes wrong
|
||||
with SIGINT handling). It works correctly under Windows 95/98/98SE/ME.

# 7z2lzma.bash is very primitive .7z to .lzma converter. The input file must
|
||||
# have exactly one LZMA compressed stream, which has been created with the
|
||||
# default lc, lp, and pb values. The CRC32 in the .7z archive is not checked,
|
||||
# and the script may seem to succeed while it actually created a corrupt .lzma
|
||||
# file. You should always try uncompressing both the original .7z and the
|
||||
# created .lzma and compare that the output is identical.
|
||||
#
|

# This script requires basic GNU tools and 7z or 7za tool from p7zip.

of `struct option' terminated by an element containing a name which is

||||
zero.
|

|

The field `has_arg' is:

no_argument (or 0) if the option does not take an argument,

required_argument (or 1) if the option requires an argument,

optional_argument (or 2) if the option takes an optional argument.

to the value given in the field `val' when the option is found, but

left unchanged if the option is not found.

|

To have a long-named option do something other than set an `int' to
|
||||
a compiled-in constant, such as set a value from `optarg', set the
|
||||
option's `flag' field to zero and its `val' field to a nonzero
|
||||
value (the equivalent single-letter option character, if there is
|
||||
one). For long options that have a zero `flag' field, `getopt'

Return the option character from OPTS just read. Return -1 when

there are no more options. For unrecognized options, or options

missing arguments, `optopt' is set to the option letter, and '?' is

returned.

The OPTS string is a list of characters which are recognized option

letters, optionally followed by colons, specifying that that letter

takes an argument, to be placed in `optarg'.
|

|

If a letter in OPTS is followed by two colons, its argument is
|

optional. This behavior is specific to the GNU `getopt'.
|

The argument `--' causes premature termination of argument
|
||||
scanning, explicitly telling `getopt' that there are no more
|
||||
options.
|

|
||||
If OPTS begins with `-', then non-option arguments are treated as
|
||||
arguments to the option '\1'. This behavior is specific to the GNU
|

`getopt'. If OPTS begins with `+', or POSIXLY_CORRECT is set in
|

the environment, then do not permute arguments. */

REQUIRE_ORDER means don't recognize them as options;

This is what Unix does.

# SYNOPSIS
|
||||
#
|
||||
# AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
|
||||
#
|
||||
# DESCRIPTION
|
||||
#
|
||||
# This macro figures out how to build C programs using POSIX threads. It
|
||||
# sets the PTHREAD_LIBS output variable to the threads library and linker
|
||||
# flags, and the PTHREAD_CFLAGS output variable to any special C compiler
|
||||
# flags that are needed. (The user can also force certain compiler
|
||||
# flags/libs to be tested by setting these environment variables.)
|
||||
#
|
||||
# Also sets PTHREAD_CC to any special C compiler that is needed for
|
||||
# multi-threaded programs (defaults to the value of CC otherwise). (This
|
||||
# is necessary on AIX to use the special cc_r compiler alias.)
|
||||
#
|
||||
# NOTE: You are assumed to not only compile your program with these flags,
|
||||
# but also link it with them as well. e.g. you should link with
|
||||
# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
|
||||
#
|
||||
# If you are only building threads programs, you may wish to use these
|
||||
# variables in your default LIBS, CFLAGS, and CC:
|
||||
#
|
||||
# LIBS="$PTHREAD_LIBS $LIBS"
|
||||
# CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
|
||||
# CC="$PTHREAD_CC"
|
||||
#
|
||||
# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
|
||||
# has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
|
||||
# (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
|
||||
#
|
||||
# Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
|
||||
# PTHREAD_PRIO_INHERIT symbol is defined when compiling with
|
||||
# PTHREAD_CFLAGS.
|
||||
#
|
||||
# ACTION-IF-FOUND is a list of shell commands to run if a threads library
|
||||
# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
|
||||
# is not found. If ACTION-IF-FOUND is not specified, the default action
|
||||
# will define HAVE_PTHREAD.
|
||||
#
|
||||
# Please let the authors know if this macro fails on any platform, or if
|
||||
# you have any other suggestions or comments. This macro was based on work
|
||||
# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
|
||||
# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
|
||||
# Alejandro Forero Cuervo to the autoconf macro repository. We are also
|
||||
# grateful for the helpful feedback of numerous users.

|
||||
|
||||
dnl Macro to add for using GNU gettext.
|
||||
|
||||
dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
|
||||
dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
|
||||
dnl default (if it is not specified or empty) is 'no-libtool'.
|
||||
dnl INTLSYMBOL should be 'external' for packages with no intl directory,
|
||||
dnl and 'no-libtool' or 'use-libtool' for packages with an intl directory.
|
||||
dnl If INTLSYMBOL is 'use-libtool', then a libtool library
|
||||
dnl $(top_builddir)/intl/libintl.la will be created (shared and/or static,
|
||||
dnl depending on --{enable,disable}-{shared,static} and on the presence of
|
||||
dnl AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
|
||||
dnl $(top_builddir)/intl/libintl.a will be created.
|
||||
dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
|
||||
dnl implementations (in libc or libintl) without the ngettext() function
|
||||
dnl will be ignored. If NEEDSYMBOL is specified and is
|
||||
dnl 'need-formatstring-macros', then GNU gettext implementations that don't
|
||||
dnl support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
|
||||
dnl INTLDIR is used to find the intl libraries. If empty,
|
||||
dnl the value `$(top_builddir)/intl/' is used.
|
||||
dnl
|
||||
dnl The result of the configuration is one of three cases:
|
||||
dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
|
||||
dnl and used.
|
||||
dnl Catalog format: GNU --> install in $(datadir)
|
||||
dnl Catalog extension: .mo after installation, .gmo in source tree
|
||||
dnl 2) GNU gettext has been found in the system's C library.
|
||||
dnl Catalog format: GNU --> install in $(datadir)
|
||||
dnl Catalog extension: .mo after installation, .gmo in source tree
|
||||
dnl 3) No internationalization, always use English msgid.
|
||||
dnl Catalog format: none
|
||||
dnl Catalog extension: none
|
||||
dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
|
||||
dnl The use of .gmo is historical (it was needed to avoid overwriting the
|
||||
dnl GNU format catalogs when building on a platform with an X/Open gettext),
|
||||
dnl but we keep it in order not to force irrelevant filename changes on the
|
||||
dnl maintainers.
