The Free Translation Project is +a way to get maintainers of free software, translators, and users all +together, so that free software will gradually become able to speak many +languages. A few packages already provide translations for their +messages. + + If you found this `ABOUT-NLS' file inside a distribution, you may +assume that the distributed package does use GNU `gettext' internally, +itself available at your nearest GNU archive site. But you do _not_ +need to install GNU `gettext' prior to configuring, installing or using +this package with messages translated. + + Installers will find here some useful hints. These notes also +explain how users should proceed for getting the programs to use the +available translations. They tell how people wanting to contribute and +work on translations can contact the appropriate team. + + When reporting bugs in the `intl/' directory or bugs which may be +related to internationalization, you should tell about the version of +`gettext' which is used. The information can be found in the +`intl/VERSION' file, in internationalized packages. + +1.1 Quick configuration advice +============================== + +If you want to exploit the full power of internationalization, you +should configure it using + + ./configure --with-included-gettext + +to force usage of internationalizing routines provided within this +package, despite the existence of internationalizing capabilities in the +operating system where this package is being installed. So far, only +the `gettext' implementation in the GNU C library version 2 provides as +many features (such as locale alias, message inheritance, automatic +charset conversion or plural form handling) as the implementation here. +It is also not possible to offer this additional functionality on top +of a `catgets' implementation. Future versions of GNU `gettext' will +very likely convey even more functionality. So it might be a good idea +to change to GNU `gettext' as soon as possible. + + So you need _not_ provide this option if you are using GNU libc 2 or +you have installed a recent copy of the GNU gettext package with the +included `libintl'. + +1.2 INSTALL Matters +=================== + +Some packages are "localizable" when properly installed; the programs +they contain can be made to speak your own native language. Most such +packages use GNU `gettext'. Other packages have their own ways to +internationalization, predating GNU `gettext'. + + By default, this package will be installed to allow translation of +messages. It will automatically detect whether the system already +provides the GNU `gettext' functions. If not, the included GNU +`gettext' library will be used. This library is wholly contained +within this package, usually in the `intl/' subdirectory, so prior +installation of the GNU `gettext' package is _not_ required. +Installers may use special options at configuration time for changing +the default behaviour. The commands: + + ./configure --with-included-gettext + ./configure --disable-nls + +will, respectively, bypass any pre-existing `gettext' to use the +internationalizing routines provided within this package, or else, +_totally_ disable translation of messages. + + When you already have GNU `gettext' installed on your system and run +configure without an option for your new package, `configure' will +probably detect the previously built and installed `libintl.a' file and +will decide to use this. This might not be desirable. You should use +the more recent version of the GNU `gettext' library. I.e. if the file +`intl/VERSION' shows that the library which comes with this package is +more recent, you should use + + ./configure --with-included-gettext + +to prevent auto-detection. + + The configuration process will not test for the `catgets' function +and therefore it will not be used. The reason is that even an +emulation of `gettext' on top of `catgets' could not provide all the +extensions of the GNU `gettext' library. + + Internationalized packages usually have many `po/LL.po' files, where +LL gives an ISO 639 two-letter code identifying the language. Unless +translations have been forbidden at `configure' time by using the +`--disable-nls' switch, all available translations are installed +together with the package. However, the environment variable `LINGUAS' +may be set, prior to configuration, to limit the installed set. +`LINGUAS' should then contain a space separated list of two-letter +codes, stating which languages are allowed. + +1.3 Using This Package +====================== + +As a user, if your language has been installed for this package, you +only have to set the `LANG' environment variable to the appropriate +`LL_CC' combination. If you happen to have the `LC_ALL' or some other +`LC_xxx' environment variables set, you should unset them before +setting `LANG', otherwise the setting of `LANG' will not have the +desired effect. Here `LL' is an ISO 639 two-letter language code, and +`CC' is an ISO 3166 two-letter country code. For example, let's +suppose that you speak German and live in Germany. At the shell +prompt, merely execute `setenv LANG de_DE' (in `csh'), +`export LANG; LANG=de_DE' (in `sh') or `export LANG=de_DE' (in `bash'). +This can be done from your `.login' or `.profile' file, once and for +all. + + You might think that the country code specification is redundant. +But in fact, some languages have dialects in different countries. For +example, `de_AT' is used for Austria, and `pt_BR' for Brazil. The +country code serves to distinguish the dialects. + + The locale naming convention of `LL_CC', with `LL' denoting the +language and `CC' denoting the country, is the one use on systems based +on GNU libc. On other systems, some variations of this scheme are +used, such as `LL' or `LL_CC.ENCODING'. You can get the list of +locales supported by your system for your language by running the +command `locale -a | grep '^LL''. + + Not all programs have translations for all languages. By default, an +English message is shown in place of a nonexistent translation. If you +understand other languages, you can set up a priority list of languages. +This is done through a different environment variable, called +`LANGUAGE'. GNU `gettext' gives preference to `LANGUAGE' over `LANG' +for the purpose of message handling, but you still need to have `LANG' +set to the primary language; this is required by other parts of the +system libraries. For example, some Swedish users who would rather +read translations in German than English for when Swedish is not +available, set `LANGUAGE' to `sv:de' while leaving `LANG' to `sv_SE'. + + Special advice for Norwegian users: The language code for Norwegian +bokma*l changed from `no' to `nb' recently (in 2003). During the +transition period, while some message catalogs for this language are +installed under `nb' and some older ones under `no', it's recommended +for Norwegian users to set `LANGUAGE' to `nb:no' so that both newer and +older translations are used. + + In the `LANGUAGE' environment variable, but not in the `LANG' +environment variable, `LL_CC' combinations can be abbreviated as `LL' +to denote the language's main dialect. For example, `de' is equivalent +to `de_DE' (German as spoken in Germany), and `pt' to `pt_PT' +(Portuguese as spoken in Portugal) in this context. + +1.4 Translating Teams +===================== + +For the Free Translation Project to be a success, we need interested +people who like their own language and write it well, and who are also +able to synergize with other translators speaking the same language. +Each translation team has its own mailing list. The up-to-date list of +teams can be found at the Free Translation Project's homepage, +`http://translationproject.org/', in the "Teams" area. + + If you'd like to volunteer to _work_ at translating messages, you +should become a member of the translating team for your own language. +The subscribing address is _not_ the same as the list itself, it has +`-request' appended. For example, speakers of Swedish can send a +message to `sv-request@li.org', having this message body: + + subscribe + + Keep in mind that team members are expected to participate +_actively_ in translations, or at solving translational difficulties, +rather than merely lurking around. If your team does not exist yet and +you want to start one, or if you are unsure about what to do or how to +get started, please write to `coordinator@translationproject.org' to +reach the coordinator for all translator teams. + + The English team is special. It works at improving and uniformizing +the terminology in use. Proven linguistic skills are praised more than +programming skills, here. + +1.5 Available Packages +====================== + +Languages are not equally supported in all packages. The following +matrix shows the current state of internationalization, as of May 2010. +The matrix shows, in regard of each package, for which languages PO +files have been submitted to translation

Of course you have to respect the GNU Library General Public +License which covers the use of the GNU `gettext' library. This means +in particular that even non-free programs can use `libintl' as a shared +library, whereas only free software can use `libintl' as a static +library or use modified versions of `libintl'. + + Once the sources are changed appropriately and the setup can handle +the use of `gettext' the only thing missing are the translations. The +Free Translation Project is also available for packages which are not +developed inside the GNU project. Therefore the information given above +applies also for every other Free Software Project.

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.

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. + + + Copyright (C) + + 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. + + , 1 April 1989 + Ty Coon, President of Vice + +This General Public License does not permit incorporating your program into +proprietary programs.

If this is what you want to do, use the GNU Lesser General +Public License instead of this License. diff --git a/COPYING.GPLv3 b/COPYING.GPLv3 new file mode 100644 index 00000000..94a9ed02 --- /dev/null +++ b/COPYING.GPLv3 @@ -0,0 +1,674 @@ + GNU GENERAL PUBLIC LICENSE + Version 3, 29 June 2007 + + Copyright (C) 2007 Free Software Foundation, Inc. + 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. + + + Copyright (C) + + 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 . + +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: + + Copyright (C) + 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 +. + + 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.

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. + + + Copyright (C) + + 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.

That + assumption was wrong (e.g. LC_ALL=fi_FI.UTF-8 with glibc), so + multibyte character support was added in this commit. The old + way is used if the operating system doesn't have enough multibyte + support (e.g. lacks wcwidth()). + + The sizes of buffers were increased to accomodate multibyte + characters. I don't know how big they should be exactly, but + they aren't used for anything critical, so it's not too bad. + If they still aren't big enough, I hopefully get a bug report. + snprintf() takes care of avoiding buffer overflows. + + Some static buffers were replaced with buffers allocated on + stack. double_to_str() was removed. uint64_to_str() and + uint64_to_nicestr() now share the static buffer and test + for thousand separator support. + + Integrity check names "None" and "Unknown-N" (2 <= N <= 15) + were marked to be translated.

On 32-bit x86 (tested on mobile XP2400+), + using PIC instead of non-PIC makes the decompressor 10 % slower + with the default CFLAGS. + + So while xz was linked against static liblzma by default, + it got the slower PIC objects unless --disable-shared was + used. I tend develop and benchmark with --disable-shared + due to faster build time, so I hadn't noticed the problem + in benchmarks earlier. + + This commit also adds support for building Windows resources + into liblzma and executables. + + configure.ac | 34 ++++++++++------ + src/liblzma/Makefile.am | 79 +++++++++++++++++++++++++++++-------- + src/liblzma/check/Makefile.am | 47 ----------------------

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 + . + + 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 . 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 file is offered as-is, +without warranty of any kind. + +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 `' 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. + diff --git a/Makefile.am b/Makefile.am new file mode 100644 index 00000000..10536971 --- /dev/null +++ b/Makefile.am @@ -0,0 +1,109 @@ +## +## Author: Lasse Collin +## +## This file has been put into the public domain. +## You can do whatever you want with this file. +## + +# Use -n to prevent gzip from adding a timestamp to the .gz headers. +GZIP_ENV = -9n + +DIST_SUBDIRS = lib src po tests debug +SUBDIRS = + +if COND_GNULIB +SUBDIRS += lib +endif + +SUBDIRS += src po tests + +if COND_DOC +dist_doc_DATA = \ + AUTHORS \ + COPYING \ + COPYING.GPLv2 \ + NEWS \ + README \ + THANKS \ + TODO \ + doc/faq.txt \ + doc/history.txt \ + doc/xz-file-format.txt \ + doc/lzma-file-format.txt + +examplesdir = $(docdir)/examples +dist_examples_DATA = \ + doc/examples/00_README.txt \ + doc/examples/01_compress_easy.c \ + doc/examples/02_decompress.c \ + doc/examples/03_compress_custom.c \ + doc/examples/04_compress_easy_mt.c \ + doc/examples/Makefile + +examplesolddir = $(docdir)/examples_old +dist_examplesold_DATA = \ + doc/examples_old/xz_pipe_comp.c \ + doc/examples_old/xz_pipe_decomp.c +endif + +EXTRA_DIST = \ + extra \ + dos \ + windows \ + macosx \ + autogen.sh \ + Doxyfile.in \ + COPYING.GPLv2 \ + COPYING.GPLv3 \ + COPYING.LGPLv2.1 \ + INSTALL.generic \ + PACKAGERS \ + build-aux/manconv.sh \ + build-aux/version.sh + +ACLOCAL_AMFLAGS = -I m4 + +# List of man pages to conver to PDF and plain text in the dist-hook target. +manfiles = \ + src/xz/xz.1 \ + src/xzdec/xzdec.1 \ + src/lzmainfo/lzmainfo.1 \ + src/scripts/xzdiff.1 \ + src/scripts/xzgrep.1 \ + src/scripts/xzless.1 \ + src/scripts/xzmore.1 + +# Create ChangeLog from output of "git log --date=iso --stat". +# Convert the man pages to PDF and plain text (ASCII only) formats. +dist-hook: + if test -d "$(srcdir)/.git" && type git > /dev/null 2>&1;

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_get_progress() in , and lzma_cputhreads() + in 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 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. + diff --git a/PACKAGERS b/PACKAGERS new file mode 100644 index 00000000..6c5d219c --- /dev/null +++ b/PACKAGERS @@ -0,0 +1,231 @@ + +Information to packagers of XZ Utils +==================================== + + 0.

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.

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 + diff --git a/README b/README new file mode 100644 index 00000000..ab8aadfb --- /dev/null +++ b/README @@ -0,0 +1,308 @@ + +XZ Utils +======== + + 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. Documentation +---------------- + +1.1.

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. + + http://zlib.net/manual.html + http://zlib.net/zlib_how.html + + +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 + # + 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. + + http://tukaani.org/xz/embedded.html + + +6. Contact information +---------------------- + + If you have questions, bug reports, patches etc. related to XZ Utils, + contact Lasse Collin (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. + diff --git a/THANKS b/THANKS new file mode 100644 index 00000000..d9c62d46 --- /dev/null +++ b/THANKS @@ -0,0 +1,116 @@ + +Thanks +====== + +Some people have helped more, some less, but nevertheless everyone's help +has been important. :-) In alphabetical order: + - Mark Adler + - H.

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.

In an in-source build this is usually +# harmless because $srcdir is '.', but things will broke when you +# start a VPATH build or use an absolute $srcdir. +# +# So we could use something similar to $top_srcdir/$ac_aux_dir/missing, +# iff we strip the leading $srcdir from $ac_aux_dir.

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 . + + +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 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 . + + +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.

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. + diff --git a/doc/lzma-file-format.txt b/doc/lzma-file-format.txt new file mode 100644 index 00000000..015b0fae --- /dev/null +++ b/doc/lzma-file-format.txt @@ -0,0 +1,166 @@ + +The .lzma File Format +===================== + + 0.

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).

The settings used + when compressing a file determine the memory requirements of the decom- + pressor. Typically the decompressor needs 5 % to 20 % of the amount of + memory that the compressor needed when creating the file. For example, + decompressing a file created with xz -9 currently requires 65 MiB of + memory. Still, it is possible to have .xz files that require several + gigabytes of memory to decompress. + + Especially users of older systems may find the possibility of very + large memory usage annoying. To prevent uncomfortable surprises, xz + has a built-in memory usage limiter, which is disabled by default. + While some operating systems provide ways to limit the memory usage of + processes, relying on it wasn't deemed to be flexible enough (e.g. + using ulimit(1) to limit virtual memory tends to cripple mmap(2)). + + The memory usage limiter can be enabled with the command line option + --memlimit=limit. Often it is more convenient to enable the limiter by + default by setting the environment variable XZ_DEFAULTS, e.g. + XZ_DEFAULTS=--memlimit=150MiB. It is possible to set the limits sepa- + rately for compression and decompression by using --memlimit-com- + press=limit and --memlimit-decompress=limit. Using these two options + outside XZ_DEFAULTS is rarely useful because a single run of xz cannot + do both compression and decompression and --memlimit=limit (or -M + limit) is shorter to type on the command line. + + If the specified memory usage limit is exceeded when decompressing, xz + will display an error and decompressing the file will fail. If the + limit is exceeded when compressing, xz will try to scale the settings + down so that the limit is no longer exceeded (except when using --for- + mat=raw or --no-adjust). This way the operation won't fail unless the + limit is very small. The scaling of the settings is done in steps that + don't match the compression level presets, e.g. if the limit is only + slightly less than the amount required for xz -9, the settings will be + scaled down only a little, not all the way down to xz -8. + + Concatenation and padding with .xz files + It is possible to concatenate .xz files as is. xz will decompress such + files as if they were a single .xz file. + + It is possible to insert padding between the concatenated parts or + after the last part. The padding must consist of null bytes and the + size of the padding must be a multiple of four bytes. This can be use- + ful e.g. if the .xz file is stored on a medium that measures file sizes + in 512-byte blocks. + + Concatenation and padding are not allowed with .lzma files or raw + streams. + +OPTIONS + Integer suffixes and special values + In most places where an integer argument is expected, an optional suf- + fix is supported to easily indicate large integers. There must be no + space between the integer and the suffix. + + KiB Multiply the integer by 1,024 (2^10). Ki, k, kB, K, and KB are + accepted as synonyms for KiB. + + MiB Multiply the integer by 1,048,576 (2^20). Mi, m, M, and MB are + accepted as synonyms for MiB. + + GiB Multiply the integer by 1,073,741,824 (2^30). Gi, g, G, and GB + are accepted as synonyms for GiB. + + The special value max can be used to indicate the maximum integer value + supported by the option. + + Operation mode + If multiple operation mode options are given, the last one takes + effect. + + -z, --compress + Compress. This is the default operation mode when no operation + mode option is specified and no other operation mode is implied + from the command name (for example, unxz implies --decompress). + + -d, --decompress, --uncompress + Decompress. + + -t, --test + Test the integrity of compressed files. This option is equiva- + lent to --decompress --stdout except that the decompressed data + is discarded instead of being written to standard output. No + files are created or removed. + + -l, --list + Print information about compressed files. No uncompressed out- + put is produced, and no files are created or removed. In list + mode, the program cannot read the compressed data from standard + input or from other unseekable sources. + + The default listing shows basic information about files, one + file per line. To get more detailed information, use also the + --verbose option. For even more information, use --verbose + twice, but note that this may be slow, because getting all the + extra information requires many seeks. The width of verbose + output exceeds 80 characters, so piping the output to e.g. + less -S may be convenient if the terminal isn't wide enough. + + The exact output may vary between xz versions and different + locales. For machine-readable output, --robot --list should be + used. + + Operation modifiers + -k, --keep + Don't delete the input files. + + -f, --force + This option has several effects: + + o If the target file already exists, delete it before compress- + ing or decompressing. + + o Compress or decompress even if the input is a symbolic link + to a regular file, has more than one hard link, or has the + setuid, setgid, or sticky bit set. The setuid, setgid, and + sticky bits are not copied to the target file. + + o When used with --decompress --stdout and xz cannot recognize + the type of the source file, copy the source file as is to + standard output. This allows xzcat --force to be used like + cat(1) for files that have not been compressed with xz. Note + that in future, xz might support new compressed file formats, + which may make xz decompress more types of files instead of + copying them as is to standard output. --format=format can + be used to restrict xz to decompress only a single file for- + mat. + + -c, --stdout, --to-stdout + Write the compressed or decompressed data to standard output + instead of a file. This implies --keep. + + --single-stream + Decompress only the first .xz stream, and silently ignore possi- + ble remaining input data following the stream. Normally such + trailing garbage makes xz display an error. + + xz never decompresses more than one stream from .lzma files or + raw streams, but this option still makes xz ignore the possible + trailing data after the .lzma file or raw stream. + + This option has no effect if the operation mode is not --decom- + press or --test. + + --no-sparse + Disable creation of sparse files. By default, if decompressing + into a regular file, xz tries to make the file sparse if the + decompressed data contains long sequences of binary zeros. It + also works when writing to standard output as long as standard + output is connected to a regular file and certain additional + conditions are met to make it safe. Creating sparse files may + save disk space and speed up the decompression by reducing the + amount of disk I/O. + + -S .suf, --suffix=.suf + When compressing, use .suf as the suffix for the target file + instead of .xz or .lzma. If not writing to standard output and + the source file already has the suffix .suf, a warning is dis- + played and the file is skipped. + + When decompressing, recognize files with the suffix .suf in + addition to files with the .xz, .txz, .lzma, or .tlz suffix. If + the source file has the suffix .suf, the suffix is removed to + get the target filename. + + When compressing or decompressing raw streams (--format=raw), + the suffix must always be specified unless writing to standard + output, because there is no default suffix for raw streams. + + --files[=file] + Read the filenames to process from file; if file is omitted, + filenames are read from standard input. Filenames must be ter- + minated with the newline character. A dash (-) is taken as a + regular filename; it doesn't mean standard input. If filenames + are given also as command line arguments, they are processed + before the filenames read from file. + + --files0[=file] + This is identical to --files[=file] except that each filename + must be terminated with the null character. + + Basic file format and compression options + -F format, --format=format + Specify the file format to compress or decompress: + + auto This is the default. When compressing, auto is equiva- + lent to xz. When decompressing, the format of the input + file is automatically detected. Note that raw streams + (created with --format=raw) cannot be auto-detected. + + xz Compress to the .xz file format, or accept only .xz files + when decompressing. + + lzma, alone + Compress to the legacy .lzma file format, or accept only + .lzma files when decompressing. The alternative name + alone is provided for backwards compatibility with LZMA + Utils. + + raw Compress or uncompress a raw stream (no headers). This + is meant for advanced users only. To decode raw streams, + you need use --format=raw and explicitly specify the fil- + ter chain, which normally would have been stored in the + container headers. + + -C check, --check=check + Specify the type of the integrity check. The check is calcu- + lated from the uncompressed data and stored in the .xz file. + This option has an effect only when compressing into the .xz + format; the .lzma format doesn't support integrity checks. The + integrity check (if any) is verified when the .xz file is decom- + pressed. + + Supported check types: + + none Don't calculate an integrity check at all. This is usu- + ally a bad idea. This can be useful when integrity of + the data is verified by other means anyway. + + crc32 Calculate CRC32 using the polynomial from IEEE-802.3 + (Ethernet). + + crc64 Calculate CRC64 using the polynomial from ECMA-182. This + is the default, since it is slightly better than CRC32 at + detecting damaged files and the speed difference is neg- + ligible. + + sha256 Calculate SHA-256. This is somewhat slower than CRC32 + and CRC64. + + Integrity of the .xz headers is always verified with CRC32. It + is not possible to change or disable it. + + --ignore-check + Don't verify the integrity check of the compressed data when + decompressing. The CRC32 values in the .xz headers will still + be verified normally. + + Do not use this option unless you know what you are doing. Pos- + sible reasons to use this option: + + o Trying to recover data from a corrupt .xz file. + + o Speeding up decompression. This matters mostly with SHA-256 + or with files that have compressed extremely well. It's rec- + ommended to not use this option for this purpose unless the + file integrity is verified externally in some other way. + + -0 ... -9 + Select a compression preset level. The default is -6. If mul- + tiple preset levels are specified, the last one takes effect. + If a custom filter chain was already specified, setting a com- + pression preset level clears the custom filter chain. + + The differences between the presets are more significant than + with gzip(1) and bzip2(1). The selected compression settings + determine the memory requirements of the decompressor, thus + using a too high preset level might make it painful to decom- + press the file on an old system with little RAM. Specifically, + it's not a good idea to blindly use -9 for everything like it + often is with gzip(1) and bzip2(1). + + -0 ... -3 + These are somewhat fast presets. -0 is sometimes faster + than gzip -9 while compressing much better. The higher + ones often have speed comparable to bzip2(1) with compa- + rable or better compression ratio, although the results + depend a lot on the type of data being compressed. + + -4 ... -6 + Good to very good compression while keeping decompressor + memory usage reasonable even for old systems. -6 is the + default, which is usually a good choice e.g. for dis- + tributing files that need to be decompressible even on + systems with only 16 MiB RAM. (-5e or -6e may be worth + considering too. See --extreme.) + + -7 ... -9 + These are like -6 but with higher compressor and decom- + pressor memory requirements. These are useful only when + compressing files bigger than 8 MiB, 16 MiB, and 32 MiB, + respectively. + + On the same hardware, the decompression speed is approximately a + constant number of bytes of compressed data per second. In + other words, the better the compression, the faster the decom- + pression will usually be. This also means that the amount of + uncompressed output produced per second can vary a lot. + + The following table summarises the features of the presets: + + Preset DictSize CompCPU CompMem DecMem + -0 256 KiB 0 3 MiB 1 MiB + -1 1 MiB 1 9 MiB 2 MiB + -2 2 MiB 2 17 MiB 3 MiB + -3 4 MiB 3 32 MiB 5 MiB + -4 4 MiB 4 48 MiB 5 MiB + -5 8 MiB 5 94 MiB 9 MiB + -6 8 MiB 6 94 MiB 9 MiB + -7 16 MiB 6 186 MiB 17 MiB + -8 32 MiB 6 370 MiB 33 MiB + -9 64 MiB 6 674 MiB 65 MiB + + Column descriptions: + + o DictSize is the LZMA2 dictionary size. It is waste of memory + to use a dictionary bigger than the size of the uncompressed + file. This is why it is good to avoid using the presets -7 + ... -9 when there's no real need for them. At -6 and lower, + the amount of memory wasted is usually low enough to not mat- + ter. + + o CompCPU is a simplified representation of the LZMA2 settings + that affect compression speed. The dictionary size affects + speed too, so while CompCPU is the same for levels -6 ... -9, + higher levels still tend to be a little slower. To get even + slower and thus possibly better compression, see --extreme. + + o CompMem contains the compressor memory requirements in the + single-threaded mode. It may vary slightly between xz ver- + sions. Memory requirements of some of the future multi- + threaded modes may be dramatically higher than that of the + single-threaded mode. + + o DecMem contains the decompressor memory requirements. That + is, the compression settings determine the memory require- + ments of the decompressor. The exact decompressor memory + usage is slightly more than the LZMA2 dictionary size, but + the values in the table have been rounded up to the next full + MiB. + + -e, --extreme + Use a slower variant of the selected compression preset level + (-0 ... -9) to hopefully get a little bit better compression + ratio, but with bad luck this can also make it worse. Decom- + pressor memory usage is not affected, but compressor memory + usage increases a little at preset levels -0 ... -3. + + Since there are two presets with dictionary sizes 4 MiB and + 8 MiB, the presets -3e and -5e use slightly faster settings + (lower CompCPU) than -4e and -6e, respectively. That way no two + presets are identical. + + Preset DictSize CompCPU CompMem DecMem + -0e 256 KiB 8 4 MiB 1 MiB + -1e 1 MiB 8 13 MiB 2 MiB + -2e 2 MiB 8 25 MiB 3 MiB + -3e 4 MiB 7 48 MiB 5 MiB + -4e 4 MiB 8 48 MiB 5 MiB + -5e 8 MiB 7 94 MiB 9 MiB + -6e 8 MiB 8 94 MiB 9 MiB + -7e 16 MiB 8 186 MiB 17 MiB + -8e 32 MiB 8 370 MiB 33 MiB + -9e 64 MiB 8 674 MiB 65 MiB + + For example, there are a total of four presets that use 8 MiB + dictionary, whose order from the fastest to the slowest is -5, + -6, -5e, and -6e. + + --fast + --best These are somewhat misleading aliases for -0 and -9, respec- + tively. These are provided only for backwards compatibility + with LZMA Utils. Avoid using these options. + + --block-size=size + When compressing to the .xz format, split the input data into + blocks of size bytes. The blocks are compressed independently + from each other, which helps with multi-threading and makes lim- + ited random-access decompression possible. This option is typi- + cally used to override the default block size in multi-threaded + mode, but this option can be used in single-threaded mode too. + + In multi-threaded mode about three times size bytes will be + allocated in each thread for buffering input and output. The + default size is three times the LZMA2 dictionary size or 1 MiB, + whichever is more. Typically a good value is 2-4 times the size + of the LZMA2 dictionary or at least 1 MiB. Using size less than + the LZMA2 dictionary size is waste of RAM because then the LZMA2 + dictionary buffer will never get fully used. The sizes of the + blocks are stored in the block headers, which a future version + of xz will use for multi-threaded decompression. + + In single-threaded mode no block splitting is done by default. + Setting this option doesn't affect memory usage. No size infor- + mation is stored in block headers, thus files created in single- + threaded mode won't be identical to files created in multi- + threaded mode. The lack of size information also means that a + future version of xz won't be able decompress the files in + multi-threaded mode. + + --block-list=sizes + When compressing to the .xz format, start a new block after the + given intervals of uncompressed data. + + The uncompressed sizes of the blocks are specified as a comma- + separated list. Omitting a size (two or more consecutive com- + mas) is a shorthand to use the size of the previous block. + + If the input file is bigger than the sum of sizes, the last + value in sizes is repeated until the end of the file. A special + value of 0 may be used as the last value to indicate that the + rest of the file should be encoded as a single block. + + If one specifies sizes that exceed the encoder's block size + (either the default value in threaded mode or the value speci- + fied with --block-size=size), the encoder will create additional + blocks while keeping the boundaries specified in sizes. For + example, if one specifies --block-size=10MiB + --block-list=5MiB,10MiB,8MiB,12MiB,24MiB and the input file is + 80 MiB, one will get 11 blocks: 5, 10, 8, 10, 2, 10, 10, 4, 10, + 10, and 1 MiB. + + In multi-threaded mode the sizes of the blocks are stored in the + block headers. This isn't done in single-threaded mode, so the + encoded output won't be identical to that of the multi-threaded + mode. + + --flush-timeout=timeout + When compressing, if more than timeout milliseconds (a positive + integer) has passed since the previous flush and reading more + input would block, all the pending input data is flushed from + the encoder and made available in the output stream. This can + be useful if xz is used to compress data that is streamed over a + network. Small timeout values make the data available at the + receiving end with a small delay, but large timeout values give + better compression ratio. + + This feature is disabled by default. If this option is speci- + fied more than once, the last one takes effect. The special + timeout value of 0 can be used to explicitly disable this fea- + ture. + + This feature is not available on non-POSIX systems. + + This feature is still experimental. Currently xz is unsuitable + for decompressing the stream in real time due to how xz does + buffering. + + --memlimit-compress=limit + Set a memory usage limit for compression. If this option is + specified multiple times, the last one takes effect. + + If the compression settings exceed the limit, xz will adjust the + settings downwards so that the limit is no longer exceeded and + display a notice that automatic adjustment was done. Such + adjustments are not made when compressing with --format=raw or + if --no-adjust has been specified. In those cases, an error is + displayed and xz will exit with exit status 1. + + The limit can be specified in multiple ways: + + o The limit can be an absolute value in bytes. Using an inte- + ger suffix like MiB can be useful. Example: --memlimit-com- + press=80MiB + + o The limit can be specified as a percentage of total physical + memory (RAM). This can be useful especially when setting the + XZ_DEFAULTS environment variable in a shell initialization + script that is shared between different computers. That way + the limit is automatically bigger on systems with more mem- + ory. Example: --memlimit-compress=70% + + o The limit can be reset back to its default value by setting + it to 0. This is currently equivalent to setting the limit + to max (no memory usage limit). Once multithreading support + has been implemented, there may be a difference between 0 and + max for the multithreaded case, so it is recommended to use 0 + instead of max until the details have been decided. + + See also the section Memory usage. + + --memlimit-decompress=limit + Set a memory usage limit for decompression. This also affects + the --list mode. If the operation is not possible without + exceeding the limit, xz will display an error and decompressing + the file will fail. See --memlimit-compress=limit for possible + ways to specify the limit. + + -M limit, --memlimit=limit, --memory=limit + This is equivalent to specifying --memlimit-compress=limit + --memlimit-decompress=limit. + + --no-adjust + Display an error and exit if the compression settings exceed the + memory usage limit. The default is to adjust the settings down- + wards so that the memory usage limit is not exceeded. Automatic + adjusting is always disabled when creating raw streams (--for- + mat=raw). + + -T threads, --threads=threads + Specify the number of worker threads to use. Setting threads to + a special value 0 makes xz use as many threads as there are CPU + cores on the system. The actual number of threads can be less + than threads if the input file is not big enough for threading + with the given settings or if using more threads would exceed + the memory usage limit. + + Currently the only threading method is to split the input into + blocks and compress them independently from each other. The + default block size depends on the compression level and can be + overriden with the --block-size=size option. + + Threaded decompression hasn't been implemented yet. It will + only work on files that contain multiple blocks with size infor- + mation in block headers. All files compressed in multi-threaded + mode meet this condition, but files compressed in single- + threaded mode don't even if --block-size=size is used. + + Custom compressor filter chains + A custom filter chain allows specifying the compression settings in + detail instead of relying on the settings associated to the presets. + When a custom filter chain is specified, preset options (-0 ... -9 and + --extreme) earlier on the command line are forgotten. If a preset + option is specified after one or more custom filter chain options, the + new preset takes effect and the custom filter chain options specified + earlier are forgotten. + + A filter chain is comparable to piping on the command line. When com- + pressing, the uncompressed input goes to the first filter, whose output + goes to the next filter (if any). The output of the last filter gets + written to the compressed file. The maximum number of filters in the + chain is four, but typically a filter chain has only one or two fil- + ters. + + Many filters have limitations on where they can be in the filter chain: + some filters can work only as the last filter in the chain, some only + as a non-last filter, and some work in any position in the chain. + Depending on the filter, this limitation is either inherent to the fil- + ter design or exists to prevent security issues. + + A custom filter chain is specified by using one or more filter options + in the order they are wanted in the filter chain. That is, the order + of filter options is significant! When decoding raw streams (--for- + mat=raw), the filter chain is specified in the same order as it was + specified when compressing. + + Filters take filter-specific options as a comma-separated list. Extra + commas in options are ignored. Every option has a default value, so + you need to specify only those you want to change. + + To see the whole filter chain and options, use xz -vv (that is, use + --verbose twice). This works also for viewing the filter chain options + used by presets. + + --lzma1[=options] + --lzma2[=options] + Add LZMA1 or LZMA2 filter to the filter chain. These filters + can be used only as the last filter in the chain. + + LZMA1 is a legacy filter, which is supported almost solely due + to the legacy .lzma file format, which supports only LZMA1. + LZMA2 is an updated version of LZMA1 to fix some practical + issues of LZMA1. The .xz format uses LZMA2 and doesn't support + LZMA1 at all. Compression speed and ratios of LZMA1 and LZMA2 + are practically the same. + + LZMA1 and LZMA2 share the same set of options: + + preset=preset + Reset all LZMA1 or LZMA2 options to preset. Preset con- + sist of an integer, which may be followed by single-let- + ter preset modifiers. The integer can be from 0 to 9, + matching the command line options -0 ... -9. The only + supported modifier is currently e, which matches + --extreme. If no preset is specified, the default values + of LZMA1 or LZMA2 options are taken from the preset 6. + + dict=size + Dictionary (history buffer) size indicates how many bytes + of the recently processed uncompressed data is kept in + memory. The algorithm tries to find repeating byte + sequences (matches) in the uncompressed data, and replace + them with references to the data currently in the dictio- + nary. The bigger the dictionary, the higher is the + chance to find a match. Thus, increasing dictionary size + usually improves compression ratio, but a dictionary big- + ger than the uncompressed file is waste of memory. + + Typical dictionary size is from 64 KiB to 64 MiB. The + minimum is 4 KiB. The maximum for compression is cur- + rently 1.5 GiB (1536 MiB). The decompressor already sup- + ports dictionaries up to one byte less than 4 GiB, which + is the maximum for the LZMA1 and LZMA2 stream formats. + + Dictionary size and match finder (mf) together determine + the memory usage of the LZMA1 or LZMA2 encoder. The same + (or bigger) dictionary size is required for decompressing + that was used when compressing, thus the memory usage of + the decoder is determined by the dictionary size used + when compressing. The .xz headers store the dictionary + size either as 2^n or 2^n + 2^(n-1), so these sizes are + somewhat preferred for compression. Other sizes will get + rounded up when stored in the .xz headers. + + lc=lc Specify the number of literal context bits. The minimum + is 0 and the maximum is 4; the default is 3. In addi- + tion, the sum of lc and lp must not exceed 4. + + All bytes that cannot be encoded as matches are encoded + as literals. That is, literals are simply 8-bit bytes + that are encoded one at a time. + + The literal coding makes an assumption that the highest + lc bits of the previous uncompressed byte correlate with + the next byte. E.g. in typical English text, an upper- + case letter is often followed by a lower-case letter, and + a lower-case letter is usually followed by another lower- + case letter. In the US-ASCII character set, the highest + three bits are 010 for upper-case letters and 011 for + lower-case letters. When lc is at least 3, the literal + coding can take advantage of this property in the uncom- + pressed data. + + The default value (3) is usually good. If you want maxi- + mum compression, test lc=4. Sometimes it helps a little, + and sometimes it makes compression worse. If it makes it + worse, test e.g. lc=2 too. + + lp=lp Specify the number of literal position bits. The minimum + is 0 and the maximum is 4; the default is 0. + + Lp affects what kind of alignment in the uncompressed + data is assumed when encoding literals. See pb below for + more information about alignment. + + pb=pb Specify the number of position bits. The minimum is 0 + and the maximum is 4; the default is 2. + + Pb affects what kind of alignment in the uncompressed + data is assumed in general. The default means four-byte + alignment (2^pb=2^2=4), which is often a good choice when + there's no better guess. + + When the aligment is known, setting pb accordingly may + reduce the file size a little. E.g. with text files hav- + ing one-byte alignment (US-ASCII, ISO-8859-*, UTF-8), + setting pb=0 can improve compression slightly. For + UTF-16 text, pb=1 is a good choice. If the alignment is + an odd number like 3 bytes, pb=0 might be the best + choice. + + Even though the assumed alignment can be adjusted with pb + and lp, LZMA1 and LZMA2 still slightly favor 16-byte + alignment. It might be worth taking into account when + designing file formats that are likely to be often com- + pressed with LZMA1 or LZMA2. + + mf=mf Match finder has a major effect on encoder speed, memory + usage, and compression ratio. Usually Hash Chain match + finders are faster than Binary Tree match finders. The + default depends on the preset: 0 uses hc3, 1-3 use hc4, + and the rest use bt4. + + The following match finders are supported. The memory + usage formulas below are rough approximations, which are + closest to the reality when dict is a power of two. + + hc3 Hash Chain with 2- and 3-byte hashing + Minimum value for nice: 3 + Memory usage: + dict * 7.5 (if dict <= 16 MiB); + dict * 5.5 + 64 MiB (if dict > 16 MiB) + + hc4 Hash Chain with 2-, 3-, and 4-byte hashing + Minimum value for nice: 4 + Memory usage: + dict * 7.5 (if dict <= 32 MiB); + dict * 6.5 (if dict > 32 MiB) + + bt2 Binary Tree with 2-byte hashing + Minimum value for nice: 2 + Memory usage: dict * 9.5 + + bt3 Binary Tree with 2- and 3-byte hashing + Minimum value for nice: 3 + Memory usage: + dict * 11.5 (if dict <= 16 MiB); + dict * 9.5 + 64 MiB (if dict > 16 MiB) + + bt4 Binary Tree with 2-, 3-, and 4-byte hashing + Minimum value for nice: 4 + Memory usage: + dict * 11.5 (if dict <= 32 MiB); + dict * 10.5 (if dict > 32 MiB) + + mode=mode + Compression mode specifies the method to analyze the data + produced by the match finder. Supported modes are fast + and normal. The default is fast for presets 0-3 and nor- + mal for presets 4-9. + + Usually fast is used with Hash Chain match finders and + normal with Binary Tree match finders. This is also what + the presets do. + + nice=nice + Specify what is considered to be a nice length for a + match. Once a match of at least nice bytes is found, the + algorithm stops looking for possibly better matches. + + Nice can be 2-273 bytes. Higher values tend to give bet- + ter compression ratio at the expense of speed. The + default depends on the preset. + + depth=depth + Specify the maximum search depth in the match finder. + The default is the special value of 0, which makes the + compressor determine a reasonable depth from mf and nice. + + Reasonable depth for Hash Chains is 4-100 and 16-1000 for + Binary Trees. Using very high values for depth can make + the encoder extremely slow with some files. Avoid set- + ting the depth over 1000 unless you are prepared to + interrupt the compression in case it is taking far too + long. + + When decoding raw streams (--format=raw), LZMA2 needs only the + dictionary size. LZMA1 needs also lc, lp, and pb. + + --x86[=options] + --powerpc[=options] + --ia64[=options] + --arm[=options] + --armthumb[=options] + --sparc[=options] + Add a branch/call/jump (BCJ) filter to the filter chain. These + filters can be used only as a non-last filter in the filter + chain. + + A BCJ filter converts relative addresses in the machine code to + their absolute counterparts. This doesn't change the size of + the data, but it increases redundancy, which can help LZMA2 to + produce 0-15 % smaller .xz file. The BCJ filters are always + reversible, so using a BCJ filter for wrong type of data doesn't + cause any data loss, although it may make the compression ratio + slightly worse. + + It is fine to apply a BCJ filter on a whole executable; there's + no need to apply it only on the executable section. Applying a + BCJ filter on an archive that contains both executable and non- + executable files may or may not give good results, so it gener- + ally isn't good to blindly apply a BCJ filter when compressing + binary packages for distribution. + + These BCJ filters are very fast and use insignificant amount of + memory. If a BCJ filter improves compression ratio of a file, + it can improve decompression speed at the same time. This is + because, on the same hardware, the decompression speed of LZMA2 + is roughly a fixed number of bytes of compressed data per sec- + ond. + + These BCJ filters have known problems related to the compression + ratio: + + o Some types of files containing executable code (e.g. object + files, static libraries, and Linux kernel modules) have the + addresses in the instructions filled with filler values. + These BCJ filters will still do the address conversion, which + will make the compression worse with these files. + + o Applying a BCJ filter on an archive containing multiple simi- + lar executables can make the compression ratio worse than not + using a BCJ filter. This is because the BCJ filter doesn't + detect the boundaries of the executable files, and doesn't + reset the address conversion counter for each executable. + + Both of the above problems will be fixed in the future in a new + filter. The old BCJ filters will still be useful in embedded + systems, because the decoder of the new filter will be bigger + and use more memory. + + Different instruction sets have have different alignment: + + Filter Alignment Notes + x86 1 32-bit or 64-bit x86 + PowerPC 4 Big endian only + ARM 4 Little endian only + ARM-Thumb 2 Little endian only + IA-64 16 Big or little endian + SPARC 4 Big or little endian + + Since the BCJ-filtered data is usually compressed with LZMA2, + the compression ratio may be improved slightly if the LZMA2 + options are set to match the alignment of the selected BCJ fil- + ter. For example, with the IA-64 filter, it's good to set pb=4 + with LZMA2 (2^4=16). The x86 filter is an exception; it's usu- + ally good to stick to LZMA2's default four-byte alignment when + compressing x86 executables. + + All BCJ filters support the same options: + + start=offset + Specify the start offset that is used when converting + between relative and absolute addresses. The offset must + be a multiple of the alignment of the filter (see the ta- + ble above). The default is zero. In practice, the + default is good; specifying a custom offset is almost + never useful. + + --delta[=options] + Add the Delta filter to the filter chain. The Delta filter can + be only used as a non-last filter in the filter chain. + + Currently only simple byte-wise delta calculation is supported. + It can be useful when compressing e.g. uncompressed bitmap + images or uncompressed PCM audio. However, special purpose + algorithms may give significantly better results than Delta + + LZMA2. This is true especially with audio, which compresses + faster and better e.g. with flac(1). + + Supported options: + + dist=distance + Specify the distance of the delta calculation in bytes. + distance must be 1-256. The default is 1. + + For example, with dist=2 and eight-byte input A1 B1 A2 B3 + A3 B5 A4 B7, the output will be A1 B1 01 02 01 02 01 02. + + Other options + -q, --quiet + Suppress warnings and notices. Specify this twice to suppress + errors too. This option has no effect on the exit status. That + is, even if a warning was suppressed, the exit status to indi- + cate a warning is still used. + + -v, --verbose + Be verbose. If standard error is connected to a terminal, xz + will display a progress indicator. Specifying --verbose twice + will give even more verbose output. + + The progress indicator shows the following information: + + o Completion percentage is shown if the size of the input file + is known. That is, the percentage cannot be shown in pipes. + + o Amount of compressed data produced (compressing) or consumed + (decompressing). + + o Amount of uncompressed data consumed (compressing) or pro- + duced (decompressing). + + o Compression ratio, which is calculated by dividing the amount + of compressed data processed so far by the amount of uncom- + pressed data processed so far. + + o Compression or decompression speed. This is measured as the + amount of uncompressed data consumed (compression) or pro- + duced (decompression) per second. It is shown after a few + seconds have passed since xz started processing the file. + + o Elapsed time in the format M:SS or H:MM:SS. + + o Estimated remaining time is shown only when the size of the + input file is known and a couple of seconds have already + passed since xz started processing the file. The time is + shown in a less precise format which never has any colons, + e.g. 2 min 30 s. + + When standard error is not a terminal, --verbose will make xz + print the filename, compressed size, uncompressed size, compres- + sion ratio, and possibly also the speed and elapsed time on a + single line to standard error after compressing or decompressing + the file. The speed and elapsed time are included only when the + operation took at least a few seconds. If the operation didn't + finish, e.g. due to user interruption, also the completion per- + centage is printed if the size of the input file is known. + + -Q, --no-warn + Don't set the exit status to 2 even if a condition worth a warn- + ing was detected. This option doesn't affect the verbosity + level, thus both --quiet and --no-warn have to be used to not + display warnings and to not alter the exit status. + + --robot + Print messages in a machine-parsable format. This is intended + to ease writing frontends that want to use xz instead of + liblzma, which may be the case with various scripts. The output + with this option enabled is meant to be stable across xz + releases. See the section ROBOT MODE for details. + + --info-memory + Display, in human-readable format, how much physical memory + (RAM) xz thinks the system has and the memory usage limits for + compression and decompression, and exit successfully. + + -h, --help + Display a help message describing the most commonly used + options, and exit successfully. + + -H, --long-help + Display a help message describing all features of xz, and exit + successfully + + -V, --version + Display the version number of xz and liblzma in human readable + format. To get machine-parsable output, specify --robot before + --version. + +ROBOT MODE + The robot mode is activated with the --robot option. It makes the out- + put of xz easier to parse by other programs. Currently --robot is sup- + ported only together with --version, --info-memory, and --list.

Even numbers are stable. Odd numbers are alpha + or beta versions. + + ZZZ Patch level for stable releases or just a counter for develop- + ment releases. + + S Stability. 0 is alpha, 1 is beta, and 2 is stable. S should be + always 2 when YYY is even. + + XYYYZZZS are the same on both lines if xz and liblzma are from the same + XZ Utils release. + + Examples: 4.999.9beta is 49990091 and 5.0.0 is 50000002. + + Memory limit information + xz --robot --info-memory prints a single line with three tab-separated + columns: + + 1.

A special value of + zero indicates the default setting, which for single-threaded mode + is the same as no limit. + + 3. Memory usage limit for decompression in bytes. A special value of + zero indicates the default setting, which for single-threaded mode + is the same as no limit. + + In the future, the output of xz --robot --info-memory may have more + columns, but never more than a single line. + + List mode + xz --robot --list uses tab-separated output.

Note that only options are parsed from the + environment variables; all non-options are silently ignored. Parsing + is done with getopt_long(3) which is used also for the command line + arguments. + + XZ_DEFAULTS + User-specific or system-wide default options. Typically this is + set in a shell initialization script to enable xz's memory usage + limiter by default. Excluding shell initialization scripts and + similar special cases, scripts must never set or unset + XZ_DEFAULTS. + + XZ_OPT This is for passing options to xz when it is not possible to set + the options directly on the xz command line. This is the case + e.g. when xz is run by a script or tool, e.g. GNU tar(1): + + XZ_OPT=-2v tar caf foo.tar.xz foo + + Scripts may use XZ_OPT e.g. to set script-specific default com- + pression options. It is still recommended to allow users to + override XZ_OPT if that is reasonable, e.g. in sh(1) scripts one + may use something like this: + + XZ_OPT=${XZ_OPT-"-7e"} + export XZ_OPT + +LZMA UTILS COMPATIBILITY + The command line syntax of xz is practically a superset of lzma, + unlzma, and lzcat as found from LZMA Utils 4.32.x. In most cases, it + is possible to replace LZMA Utils with XZ Utils without breaking exist- + ing scripts. There are some incompatibilities though, which may some- + times cause problems. + + Compression preset levels + The numbering of the compression level presets is not identical in xz + and LZMA Utils. The most important difference is how dictionary sizes + are mapped to different presets. Dictionary size is roughly equal to + the decompressor memory usage. + + Level xz LZMA Utils + -0 256 KiB N/A + -1 1 MiB 64 KiB + -2 2 MiB 1 MiB + -3 4 MiB 512 KiB + -4 4 MiB 1 MiB + -5 8 MiB 2 MiB + -6 8 MiB 4 MiB + -7 16 MiB 8 MiB + -8 32 MiB 16 MiB + -9 64 MiB 32 MiB + + The dictionary size differences affect the compressor memory usage too, + but there are some other differences between LZMA Utils and XZ Utils, + which make the difference even bigger: + + Level xz LZMA Utils 4.32.x + -0 3 MiB N/A + -1 9 MiB 2 MiB + -2 17 MiB 12 MiB + -3 32 MiB 12 MiB + -4 48 MiB 16 MiB + -5 94 MiB 26 MiB + -6 94 MiB 45 MiB + -7 186 MiB 83 MiB + -8 370 MiB 159 MiB + -9 674 MiB 311 MiB + + The default preset level in LZMA Utils is -7 while in XZ Utils it is + -6, so both use an 8 MiB dictionary by default. + + Streamed vs. non-streamed .lzma files + The uncompressed size of the file can be stored in the .lzma header. + LZMA Utils does that when compressing regular files. The alternative + is to mark that uncompressed size is unknown and use end-of-payload + marker to indicate where the decompressor should stop. LZMA Utils uses + this method when uncompressed size isn't known, which is the case for + example in pipes. + + xz supports decompressing .lzma files with or without end-of-payload + marker, but all .lzma files created by xz will use end-of-payload + marker and have uncompressed size marked as unknown in the .lzma + header. This may be a problem in some uncommon situations. For exam- + ple, a .lzma decompressor in an embedded device might work only with + files that have known uncompressed size. If you hit this problem, you + need to use LZMA Utils or LZMA SDK to create .lzma files with known + uncompressed size. + + Unsupported .lzma files + The .lzma format allows lc values up to 8, and lp values up to 4. LZMA + Utils can decompress files with any lc and lp, but always creates files + with lc=3 and lp=0. Creating files with other lc and lp is possible + with xz and with LZMA SDK. + + The implementation of the LZMA1 filter in liblzma requires that the sum + of lc and lp must not exceed 4. Thus, .lzma files, which exceed this + limitation, cannot be decompressed with xz. + + LZMA Utils creates only .lzma files which have a dictionary size of 2^n + (a power of 2) but accepts files with any dictionary size. liblzma + accepts only .lzma files which have a dictionary size of 2^n or 2^n + + 2^(n-1). This is to decrease false positives when detecting .lzma + files. + + These limitations shouldn't be a problem in practice, since practically + all .lzma files have been compressed with settings that liblzma will + accept. + + Trailing garbage + When decompressing, LZMA Utils silently ignore everything after the + first .lzma stream. In most situations, this is a bug. This also + means that LZMA Utils don't support decompressing concatenated .lzma + files. + + If there is data left after the first .lzma stream, xz considers the + file to be corrupt unless --single-stream was used. This may break + obscure scripts which have assumed that trailing garbage is ignored. + +NOTES + Compressed output may vary + The exact compressed output produced from the same uncompressed input + file may vary between XZ Utils versions even if compression options are + identical. This is because the encoder can be improved (faster or bet- + ter compression) without affecting the file format. The output can + vary even between different builds of the same XZ Utils version, if + different build options are used. + + The above means that once --rsyncable has been implemented, the result- + ing files won't necessarily be rsyncable unless both old and new files + have been compressed with the same xz version. This problem can be + fixed if a part of the encoder implementation is frozen to keep rsynca- + ble output stable across xz versions. + + Embedded .xz decompressors + Embedded .xz decompressor implementations like XZ Embedded don't neces- + sarily support files created with integrity check types other than none + and crc32. Since the default is --check=crc64, you must use + --check=none or --check=crc32 when creating files for embedded systems. + + Outside embedded systems, all .xz format decompressors support all the + check types, or at least are able to decompress the file without veri- + fying the integrity check if the particular check is not supported. + + XZ Embedded supports BCJ filters, but only with the default start off- + set. + +EXAMPLES + Basics + Compress the file foo into foo.xz using the default compression level + (-6), and remove foo if compression is successful: + + xz foo + + Decompress bar.xz into bar and don't remove bar.xz even if decompres- + sion is successful: + + xz -dk bar.xz + + Create baz.tar.xz with the preset -4e (-4 --extreme), which is slower + than e.g. the default -6, but needs less memory for compression and + decompression (48 MiB and 5 MiB, respectively): + + tar cf - baz | xz -4e > baz.tar.xz + + A mix of compressed and uncompressed files can be decompressed to stan- + dard output with a single command: + + xz -dcf a.txt b.txt.xz c.txt d.txt.lzma > abcd.txt + + Parallel compression of many files + On GNU and *BSD, find(1) and xargs(1) can be used to parallelize com- + pression of many files: + + find . -type f \! -name '*.xz' -print0 \ + | xargs -0r -P4 -n16 xz -T1 + + The -P option to xargs(1) sets the number of parallel xz processes. + The best value for the -n option depends on how many files there are to + be compressed. If there are only a couple of files, the value should + probably be 1; with tens of thousands of files, 100 or even more may be + appropriate to reduce the number of xz processes that xargs(1) will + eventually create. + + The option -T1 for xz is there to force it to single-threaded mode, + because xargs(1) is used to control the amount of parallelization. + + Robot mode + Calculate how many bytes have been saved in total after compressing + multiple files: + + xz --robot --list *.xz | awk '/^totals/{print $5-$4}' + + A script may want to know that it is using new enough xz.

This can be useful, because the presets cover only a subset of + the potentially useful combinations of compression settings. + + The CompCPU columns of the tables from the descriptions of the options + -0 ... -9 and --extreme are useful when customizing LZMA2 presets. + Here are the relevant parts collected from those two tables: + + Preset CompCPU + -0 0 + -1 1 + + -2 2 + -3 3 + -4 4 + -5 5 + -6 6 + -5e 7 + -6e 8 + + If you know that a file requires somewhat big dictionary (e.g. 32 MiB) + to compress well, but you want to compress it quicker than xz -8 would + do, a preset with a low CompCPU value (e.g. 1) can be modified to use a + bigger dictionary: + + xz --lzma2=preset=1,dict=32MiB foo.tar + + With certain files, the above command may be faster than xz -6 while + compressing significantly better. However, it must be emphasized that + only some files benefit from a big dictionary while keeping the CompCPU + value low. The most obvious situation, where a big dictionary can help + a lot, is an archive containing very similar files of at least a few + megabytes each. The dictionary size has to be significantly bigger + than any individual file to allow LZMA2 to take full advantage of the + similarities between consecutive files. + + If very high compressor and decompressor memory usage is fine, and the + file being compressed is at least several hundred megabytes, it may be + useful to use an even bigger dictionary than the 64 MiB that xz -9 + would use: + + xz -vv --lzma2=dict=192MiB big_foo.tar + + Using -vv (--verbose --verbose) like in the above example can be useful + to see the memory requirements of the compressor and decompressor. + Remember that using a dictionary bigger than the size of the uncom- + pressed file is waste of memory, so the above command isn't useful for + small files. + + Sometimes the compression time doesn't matter, but the decompressor + memory usage has to be kept low e.g. to make it possible to decompress + the file on an embedded system. The following command uses -6e (-6 + --extreme) as a base and sets the dictionary to only 64 KiB. The + resulting file can be decompressed with XZ Embedded (that's why there + is --check=crc32) using about 100 KiB of memory. + + xz --check=crc32 --lzma2=preset=6e,dict=64KiB foo + + If you want to squeeze out as many bytes as possible, adjusting the + number of literal context bits (lc) and number of position bits (pb) + can sometimes help. Adjusting the number of literal position bits (lp) + might help too, but usually lc and pb are more important. E.g. a + source code archive contains mostly US-ASCII text, so something like + the following might give slightly (like 0.1 %) smaller file than xz -6e + (try also without lc=4): + + xz --lzma2=preset=6e,pb=0,lc=4 source_code.tar + + Using another filter together with LZMA2 can improve compression with + certain file types. E.g. to compress a x86-32 or x86-64 shared library + using the x86 BCJ filter: + + xz --x86 --lzma2 libfoo.so + + Note that the order of the filter options is significant. If --x86 is + specified after --lzma2, xz will give an error, because there cannot be + any filter after LZMA2, and also because the x86 BCJ filter cannot be + used as the last filter in the chain. + + The Delta filter together with LZMA2 can give good results with bitmap + images. It should usually beat PNG, which has a few more advanced fil- + ters than simple delta but uses Deflate for the actual compression. + + The image has to be saved in uncompressed format, e.g. as uncompressed + TIFF. The distance parameter of the Delta filter is set to match the + number of bytes per pixel in the image. E.g. 24-bit RGB bitmap needs + dist=3, and it is also good to pass pb=0 to LZMA2 to accommodate the + three-byte alignment: + + xz --delta=dist=3 --lzma2=pb=0 foo.tiff + + If multiple images have been put into a single archive (e.g. .tar), the + Delta filter will work on that too as long as all images have the same + number of bytes per pixel. + +SEE ALSO + xzdec(1), xzdiff(1), xzgrep(1), xzless(1), xzmore(1), gzip(1), + bzip2(1), 7z(1) + + XZ Utils: + XZ Embedded: + LZMA SDK: + + + +Tukaani 2015-05-11 XZ(1) diff --git a/doc/man/txt/xzdec.txt b/doc/man/txt/xzdec.txt new file mode 100644 index 00000000..3d69ff3f --- /dev/null +++ b/doc/man/txt/xzdec.txt @@ -0,0 +1,80 @@ +XZDEC(1) XZ Utils XZDEC(1) + + + +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.

Conventions + + The key words "MUST", "MUST NOT", "REQUIRED", "SHOULD", + "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this + document are to be interpreted as described in [RFC-2119]. + + Indicating a warning means displaying a message, returning + appropriate exit status, or doing something else to let the + user know that something worth warning occurred. The operation + SHOULD still finish if a warning is indicated. + + Indicating an error means displaying a message, returning + appropriate exit status, or doing something else to let the + user know that something prevented successfully finishing the + operation. The operation MUST be aborted once an error has + been indicated. + + +1.1. Byte and Its Representation + + In this document, byte is always 8 bits. + + A "null byte" has all bits unset. That is, the value of a null + byte is 0x00. + + To represent byte blocks, this document uses notation that + is similar to the notation used in [RFC-1952]: + + +-------+ + | Foo | One byte. + +-------+ + + +---+---+ + | Foo | Two bytes; that is, some of the vertical bars + +---+---+ can be missing. + + +=======+ + | Foo | Zero or more bytes. + +=======+ + + In this document, a boxed byte or a byte sequence declared + using this notation is called "a field". The example field + above would be called "the Foo field" or plain "Foo". + + If there are many fields, they may be split to multiple lines. + This is indicated with an arrow ("--->"): + + +=====+ + | Foo | + +=====+ + + +=====+ + ---> | Bar | + +=====+ + + The above is equivalent to this: + + +=====+=====+ + | Foo | Bar | + +=====+=====+ + + +1.2. Multibyte Integers + + Multibyte integers of static length, such as CRC values, + are stored in little endian byte order (least significant + byte first). + + When smaller values are more likely than bigger values (for + example file sizes), multibyte integers are encoded in a + variable-length representation: + - Numbers in the range [0, 127] are copied as is, and take + one byte of space. + - Bigger numbers will occupy two or more bytes. All but the + last byte of the multibyte representation have the highest + (eighth) bit set. + + For now, the value of the variable-length integers is limited + to 63 bits, which limits the encoded size of the integer to + nine bytes. These limits may be increased in the future if + needed. + + The following C code illustrates encoding and decoding of + variable-length integers. The functions return the number of + bytes occupied by the integer (1-9), or zero on error. + + #include + #include + + size_t + encode(uint8_t buf[static 9], uint64_t num) + { + if (num > UINT64_MAX / 2) + return 0; + + size_t i = 0; + + while (num >= 0x80) { + buf[i++] = (uint8_t)(num) | 0x80; + num >>= 7; + } + + buf[i++] = (uint8_t)(num); + + return i; + } + + size_t + decode(const uint8_t buf[], size_t size_max, uint64_t *num) + { + if (size_max == 0) + return 0; + + if (size_max > 9) + size_max = 9; + + *num = buf[0] & 0x7F; + size_t i = 0; + + while (buf[i++] & 0x80) { + if (i >= size_max || buf[i] == 0x00) + return 0; + + *num |= (uint64_t)(buf[i] & 0x7F) << (i * 7); + } + + return i; + } + + +2. Overall Structure of .xz File + + A standalone .xz files consist of one or more Streams which may + have Stream Padding between or after them: + + +========+================+========+================+ + | Stream | Stream Padding | Stream | Stream Padding | ... + +========+================+========+================+ + + The sizes of Stream and Stream Padding are always multiples + of four bytes, thus the size of every valid .xz file MUST be + a multiple of four bytes. + + While a typical file contains only one Stream and no Stream + Padding, a decoder handling standalone .xz files SHOULD support + files that have more than one Stream or Stream Padding. + + In contrast to standalone .xz files, when the .xz file format + is used as an internal part of some other file format or + communication protocol, it usually is expected that the decoder + stops after the first Stream, and doesn't look for Stream + Padding or possibly other Streams. + + +2.1. Stream + + +-+-+-+-+-+-+-+-+-+-+-+-+=======+=======+ +=======+ + | Stream Header | Block | Block | ... | Block | + +-+-+-+-+-+-+-+-+-+-+-+-+=======+=======+ +=======+ + + +=======+-+-+-+-+-+-+-+-+-+-+-+-+ + ---> | Index | Stream Footer | + +=======+-+-+-+-+-+-+-+-+-+-+-+-+ + + All the above fields have a size that is a multiple of four. If + Stream is used as an internal part of another file format, it + is RECOMMENDED to make the Stream start at an offset that is + a multiple of four bytes. + + Stream Header, Index, and Stream Footer are always present in + a Stream. The maximum size of the Index field is 16 GiB (2^34). + + There are zero or more Blocks. The maximum number of Blocks is + limited only by the maximum size of the Index field. + + Total size of a Stream MUST be less than 8 EiB (2^63 bytes). + The same limit applies to the total amount of uncompressed + data stored in a Stream. + + If an implementation supports handling .xz files with multiple + concatenated Streams, it MAY apply the above limits to the file + as a whole instead of limiting per Stream basis. + + +2.1.1. Stream Header + + +---+---+---+---+---+---+-------+------+--+--+--+--+ + | Header Magic Bytes | Stream Flags | CRC32 | + +---+---+---+---+---+---+-------+------+--+--+--+--+ + + +2.1.1.1. Header Magic Bytes + + The first six (6) bytes of the Stream are so called Header + Magic Bytes. They can be used to identify the file type. + + Using a C array and ASCII: + const uint8_t HEADER_MAGIC[6] + = { 0xFD, '7', 'z', 'X', 'Z', 0x00 }; + + In plain hexadecimal: + FD 37 7A 58 5A 00 + + Notes: + - The first byte (0xFD) was chosen so that the files cannot + be erroneously detected as being in .lzma format, in which + the first byte is in the range [0x00, 0xE0]. + - The sixth byte (0x00) was chosen to prevent applications + from misdetecting the file as a text file. + + If the Header Magic Bytes don't match, the decoder MUST + indicate an error. + + +2.1.1.2. Stream Flags + + The first byte of Stream Flags is always a null byte. In the + future, this byte may be used to indicate a new Stream version + or other Stream properties. + + The second byte of Stream Flags is a bit field: + + Bit(s) Mask Description + 0-3 0x0F Type of Check (see Section 3.4): + ID Size Check name + 0x00 0 bytes None + 0x01 4 bytes CRC32 + 0x02 4 bytes (Reserved) + 0x03 4 bytes (Reserved) + 0x04 8 bytes CRC64 + 0x05 8 bytes (Reserved) + 0x06 8 bytes (Reserved) + 0x07 16 bytes (Reserved) + 0x08 16 bytes (Reserved) + 0x09 16 bytes (Reserved) + 0x0A 32 bytes SHA-256 + 0x0B 32 bytes (Reserved) + 0x0C 32 bytes (Reserved) + 0x0D 64 bytes (Reserved) + 0x0E 64 bytes (Reserved) + 0x0F 64 bytes (Reserved) + 4-7 0xF0 Reserved for future use; MUST be zero for now. + + Implementations SHOULD support at least the Check IDs 0x00 + (None) and 0x01 (CRC32). Supporting other Check IDs is + OPTIONAL. If an unsupported Check is used, the decoder SHOULD + indicate a warning or error. + + If any reserved bit is set, the decoder MUST indicate an error. + It is possible that there is a new field present which the + decoder is not aware of, and can thus parse the Stream Header + incorrectly. + + +2.1.1.3. CRC32 + + The CRC32 is calculated from the Stream Flags field. It is + stored as an unsigned 32-bit little endian integer. If the + calculated value does not match the stored one, the decoder + MUST indicate an error. + + The idea is that Stream Flags would always be two bytes, even + if new features are needed. This way old decoders will be able + to verify the CRC32 calculated from Stream Flags, and thus + distinguish between corrupt files (CRC32 doesn't match) and + files that the decoder doesn't support (CRC32 matches but + Stream Flags has reserved bits set). + + +2.1.2. Stream Footer + + +-+-+-+-+---+---+---+---+-------+------+----------+---------+ + | CRC32 | Backward Size | Stream Flags | Footer Magic Bytes | + +-+-+-+-+---+---+---+---+-------+------+----------+---------+ + + +2.1.2.1. CRC32 + + The CRC32 is calculated from the Backward Size and Stream Flags + fields. It is stored as an unsigned 32-bit little endian + integer. If the calculated value does not match the stored one, + the decoder MUST indicate an error. + + The reason to have the CRC32 field before the Backward Size and + Stream Flags fields is to keep the four-byte fields aligned to + a multiple of four bytes. + + +2.1.2.2. Backward Size + + Backward Size is stored as a 32-bit little endian integer, + which indicates the size of the Index field as multiple of + four bytes, minimum value being four bytes: + + real_backward_size = (stored_backward_size + 1) * 4; + + If the stored value does not match the real size of the Index + field, the decoder MUST indicate an error. + + Using a fixed-size integer to store Backward Size makes + it slightly simpler to parse the Stream Footer when the + application needs to parse the Stream backwards. + + +2.1.2.3. Stream Flags + + This is a copy of the Stream Flags field from the Stream + Header. The information stored to Stream Flags is needed + when parsing the Stream backwards. The decoder MUST compare + the Stream Flags fields in both Stream Header and Stream + Footer, and indicate an error if they are not identical. + + +2.1.2.4. Footer Magic Bytes + + As the last step of the decoding process, the decoder MUST + verify the existence of Footer Magic Bytes. If they don't + match, an error MUST be indicated. + + Using a C array and ASCII: + const uint8_t FOOTER_MAGIC[2] = { 'Y', 'Z' }; + + In hexadecimal: + 59 5A + + The primary reason to have Footer Magic Bytes is to make + it easier to detect incomplete files quickly, without + uncompressing. If the file does not end with Footer Magic Bytes + (excluding Stream Padding described in Section 2.2), it cannot + be undamaged, unless someone has intentionally appended garbage + after the end of the Stream. + + +2.2. Stream Padding + + Only the decoders that support decoding of concatenated Streams + MUST support Stream Padding. + + Stream Padding MUST contain only null bytes. To preserve the + four-byte alignment of consecutive Streams, the size of Stream + Padding MUST be a multiple of four bytes. Empty Stream Padding + is allowed. If these requirements are not met, the decoder MUST + indicate an error. + + Note that non-empty Stream Padding is allowed at the end of the + file; there doesn't need to be a new Stream after non-empty + Stream Padding. This can be convenient in certain situations + [GNU-tar]. + + The possibility of Stream Padding MUST be taken into account + when designing an application that parses Streams backwards, + and the application supports concatenated Streams. + + +3.

Block Header Size + + This field overlaps with the Index Indicator field (see + Section 4.1). + + This field contains the size of the Block Header field, + including the Block Header Size field itself. Valid values are + in the range [0x01, 0xFF], which indicate the size of the Block + Header as multiples of four bytes, minimum size being eight + bytes: + + real_header_size = (encoded_header_size + 1) * 4; + + If a Block Header bigger than 1024 bytes is needed in the + future, a new field can be added between the Block Header and + Compressed Data fields. The presence of this new field would + be indicated in the Block Header field. + + +3.1.2. Block Flags + + The Block Flags field is a bit field: + + Bit(s) Mask Description + 0-1 0x03 Number of filters (1-4) + 2-5 0x3C Reserved for future use; MUST be zero for now. + 6 0x40 The Compressed Size field is present. + 7 0x80 The Uncompressed Size field is present. + + If any reserved bit is set, the decoder MUST indicate an error. + It is possible that there is a new field present which the + decoder is not aware of, and can thus parse the Block Header + incorrectly. + + +3.1.3. Compressed Size + + This field is present only if the appropriate bit is set in + the Block Flags field (see Section 3.1.2). + + The Compressed Size field contains the size of the Compressed + Data field, which MUST be non-zero. Compressed Size is stored + using the encoding described in Section 1.2. If the Compressed + Size doesn't match the size of the Compressed Data field, the + decoder MUST indicate an error. + + +3.1.4. Uncompressed Size + + This field is present only if the appropriate bit is set in + the Block Flags field (see Section 3.1.2). + + The Uncompressed Size field contains the size of the Block + after uncompressing. Uncompressed Size is stored using the + encoding described in Section 1.2. If the Uncompressed Size + does not match the real uncompressed size, the decoder MUST + indicate an error. + + Storing the Compressed Size and Uncompressed Size fields serves + several purposes: + - The decoder knows how much memory it needs to allocate + for a temporary buffer in multithreaded mode. + - Simple error detection: wrong size indicates a broken file. + - Seeking forwards to a specific location in streamed mode. + + It should be noted that the only reliable way to determine + the real uncompressed size is to uncompress the Block, + because the Block Header and Index fields may contain + (intentionally or unintentionally) invalid information. + + +3.1.5. List of Filter Flags + + +================+================+ +================+ + | Filter 0 Flags | Filter 1 Flags | ... | Filter n Flags | + +================+================+ +================+ + + The number of Filter Flags fields is stored in the Block Flags + field (see Section 3.1.2). + + The format of each Filter Flags field is as follows: + + +===========+====================+===================+ + | Filter ID | Size of Properties | Filter Properties | + +===========+====================+===================+ + + Both Filter ID and Size of Properties are stored using the + encoding described in Section 1.2. Size of Properties indicates + the size of the Filter Properties field as bytes. The list of + officially defined Filter IDs and the formats of their Filter + Properties are described in Section 5.3. + + Filter IDs greater than or equal to 0x4000_0000_0000_0000 + (2^62) are reserved for implementation-specific internal use. + These Filter IDs MUST never be used in List of Filter Flags. + + +3.1.6. Header Padding + + This field contains as many null byte as it is needed to make + the Block Header have the size specified in Block Header Size. + If any of the bytes are not null bytes, the decoder MUST + indicate an error. It is possible that there is a new field + present which the decoder is not aware of, and can thus parse + the Block Header incorrectly. + + +3.1.7. CRC32 + + The CRC32 is calculated over everything in the Block Header + field except the CRC32 field itself. It is stored as an + unsigned 32-bit little endian integer. If the calculated + value does not match the stored one, the decoder MUST indicate + an error. + + By verifying the CRC32 of the Block Header before parsing the + actual contents allows the decoder to distinguish between + corrupt and unsupported files. + + +3.2. Compressed Data + + The format of Compressed Data depends on Block Flags and List + of Filter Flags. Excluding the descriptions of the simplest + filters in Section 5.3, the format of the filter-specific + encoded data is out of scope of this document. + + +3.3. Block Padding + + Block Padding MUST contain 0-3 null bytes to make the size of + the Block a multiple of four bytes. This can be needed when + the size of Compressed Data is not a multiple of four. If any + of the bytes in Block Padding are not null bytes, the decoder + MUST indicate an error. + + +3.4. Check + + The type and size of the Check field depends on which bits + are set in the Stream Flags field (see Section 2.1.1.2). + + The Check, when used, is calculated from the original + uncompressed data. If the calculated Check does not match the + stored one, the decoder MUST indicate an error. If the selected + type of Check is not supported by the decoder, it SHOULD + indicate a warning or error. + + +4. Index + + +-----------------+===================+ + | Index Indicator | Number of Records | + +-----------------+===================+ + + +=================+===============+-+-+-+-+ + ---> | List of Records | Index Padding | CRC32 | + +=================+===============+-+-+-+-+ + + Index serves several purposes. Using it, one can + - verify that all Blocks in a Stream have been processed; + - find out the uncompressed size of a Stream; and + - quickly access the beginning of any Block (random access). + + +4.1. Index Indicator + + This field overlaps with the Block Header Size field (see + Section 3.1.1). The value of Index Indicator is always 0x00. + + +4.2. Number of Records + + This field indicates how many Records there are in the List + of Records field, and thus how many Blocks there are in the + Stream. The value is stored using the encoding described in + Section 1.2. If the decoder has decoded all the Blocks of the + Stream, and then notices that the Number of Records doesn't + match the real number of Blocks, the decoder MUST indicate an + error. + + +4.3. List of Records + + List of Records consists of as many Records as indicated by the + Number of Records field: + + +========+========+ + | Record | Record | ... + +========+========+ + + Each Record contains information about one Block: + + +===============+===================+ + | Unpadded Size | Uncompressed Size | + +===============+===================+ + + If the decoder has decoded all the Blocks of the Stream, it + MUST verify that the contents of the Records match the real + Unpadded Size and Uncompressed Size of the respective Blocks. + + Implementation hint: It is possible to verify the Index with + constant memory usage by calculating for example SHA-256 of + both the real size values and the List of Records, then + comparing the hash values. Implementing this using + non-cryptographic hash like CRC32 SHOULD be avoided unless + small code size is important. + + If the decoder supports random-access reading, it MUST verify + that Unpadded Size and Uncompressed Size of every completely + decoded Block match the sizes stored in the Index. If only + partial Block is decoded, the decoder MUST verify that the + processed sizes don't exceed the sizes stored in the Index. + + +4.3.1. Unpadded Size + + This field indicates the size of the Block excluding the Block + Padding field. That is, Unpadded Size is the size of the Block + Header, Compressed Data, and Check fields. Unpadded Size is + stored using the encoding described in Section 1.2. The value + MUST never be zero; with the current structure of Blocks, the + actual minimum value for Unpadded Size is five. + + Implementation note: Because the size of the Block Padding + field is not included in Unpadded Size, calculating the total + size of a Stream or doing random-access reading requires + calculating the actual size of the Blocks by rounding Unpadded + Sizes up to the next multiple of four. + + The reason to exclude Block Padding from Unpadded Size is to + ease making a raw copy of Compressed Data without Block + Padding. This can be useful, for example, if someone wants + to convert Streams to some other file format quickly. + + +4.3.2. Uncompressed Size + + This field indicates the Uncompressed Size of the respective + Block as bytes. The value is stored using the encoding + described in Section 1.2. + + +4.4. Index Padding + + This field MUST contain 0-3 null bytes to pad the Index to + a multiple of four bytes. If any of the bytes are not null + bytes, the decoder MUST indicate an error. + + +4.5. CRC32 + + The CRC32 is calculated over everything in the Index field + except the CRC32 field itself. The CRC32 is stored as an + unsigned 32-bit little endian integer. If the calculated + value does not match the stored one, the decoder MUST indicate + an error. + + +5. Filter Chains + + The Block Flags field defines how many filters are used. When + more than one filter is used, the filters are chained; that is, + the output of one filter is the input of another filter. The + following figure illustrates the direction of data flow. + + v Uncompressed Data ^ + | Filter 0 | + Encoder | Filter 1 | Decoder + | Filter n | + v Compressed Data ^ + + +5.1. Alignment + + Alignment of uncompressed input data is usually the job of + the application producing the data. For example, to get the + best results, an archiver tool should make sure that all + PowerPC executable files in the archive stream start at + offsets that are multiples of four bytes. + + Some filters, for example LZMA2, can be configured to take + advantage of specified alignment of input data. Note that + taking advantage of aligned input can be beneficial also when + a filter is not the first filter in the chain. For example, + if you compress PowerPC executables, you may want to use the + PowerPC filter and chain that with the LZMA2 filter. Because + not only the input but also the output alignment of the PowerPC + filter is four bytes, it is now beneficial to set LZMA2 + settings so that the LZMA2 encoder can take advantage of its + four-byte-aligned input data. + + The output of the last filter in the chain is stored to the + Compressed Data field, which is is guaranteed to be aligned + to a multiple of four bytes relative to the beginning of the + Stream. This can increase + - speed, if the filtered data is handled multiple bytes at + a time by the filter-specific encoder and decoder, + because accessing aligned data in computer memory is + usually faster; and + - compression ratio, if the output data is later compressed + with an external compression tool. + + +5.2. Security + + If filters would be allowed to be chained freely, it would be + possible to create malicious files, that would be very slow to + decode. Such files could be used to create denial of service + attacks. + + Slow files could occur when multiple filters are chained: + + v Compressed input data + | Filter 1 decoder (last filter) + | Filter 0 decoder (non-last filter) + v Uncompressed output data + + The decoder of the last filter in the chain produces a lot of + output from little input. Another filter in the chain takes the + output of the last filter, and produces very little output + while consuming a lot of input. As a result, a lot of data is + moved inside the filter chain, but the filter chain as a whole + gets very little work done. + + To prevent this kind of slow files, there are restrictions on + how the filters can be chained. These restrictions MUST be + taken into account when designing new filters. + + The maximum number of filters in the chain has been limited to + four, thus there can be at maximum of three non-last filters. + Of these three non-last filters, only two are allowed to change + the size of the data. + + The non-last filters, that change the size of the data, MUST + have a limit how much the decoder can compress the data: the + decoder SHOULD produce at least n bytes of output when the + filter is given 2n bytes of input. This limit is not + absolute, but significant deviations MUST be avoided. + + The above limitations guarantee that if the last filter in the + chain produces 4n bytes of output, the chain as a whole will + produce at least n bytes of output. + + +5.3. Filters + +5.3.1. LZMA2 + + LZMA (Lempel-Ziv-Markov chain-Algorithm) is a general-purpose + compression algorithm with high compression ratio and fast + decompression. LZMA is based on LZ77 and range coding + algorithms. + + LZMA2 is an extension on top of the original LZMA. LZMA2 uses + LZMA internally, but adds support for flushing the encoder, + uncompressed chunks, eases stateful decoder implementations, + and improves support for multithreading. Thus, the plain LZMA + will not be supported in this file format. + + Filter ID: 0x21 + Size of Filter Properties: 1 byte + Changes size of data: Yes + Allow as a non-last filter: No + Allow as the last filter: Yes + + Preferred alignment: + Input data: Adjustable to 1/2/4/8/16 byte(s) + Output data: 1 byte + + The format of the one-byte Filter Properties field is as + follows: + + Bits Mask Description + 0-5 0x3F Dictionary Size + 6-7 0xC0 Reserved for future use; MUST be zero for now. + + Dictionary Size is encoded with one-bit mantissa and five-bit + exponent.

Branch/Call/Jump Filters for Executables + + These filters convert relative branch, call, and jump + instructions to their absolute counterparts in executable + files. This conversion increases redundancy and thus + compression ratio. + + Size of Filter Properties: 0 or 4 bytes + Changes size of data: No + Allow as a non-last filter: Yes + Allow as the last filter: No + + Below is the list of filters in this category. The alignment + is the same for both input and output data. + + Filter ID Alignment Description + 0x04 1 byte x86 filter (BCJ) + 0x05 4 bytes PowerPC (big endian) filter + 0x06 16 bytes IA64 filter + 0x07 4 bytes ARM (little endian) filter + 0x08 2 bytes ARM Thumb (little endian) filter + 0x09 4 bytes SPARC filter + + If the size of Filter Properties is four bytes, the Filter + Properties field contains the start offset used for address + conversions. It is stored as an unsigned 32-bit little endian + integer. The start offset MUST be a multiple of the alignment + of the filter as listed in the table above; if it isn't, the + decoder MUST indicate an error. If the size of Filter + Properties is zero, the start offset is zero. + + Setting the start offset may be useful if an executable has + multiple sections, and there are many cross-section calls. + Taking advantage of this feature usually requires usage of + the Subblock filter, whose design is not complete yet. + + +5.3.3. Delta + + The Delta filter may increase compression ratio when the value + of the next byte correlates with the value of an earlier byte + at specified distance. + + Filter ID: 0x03 + Size of Filter Properties: 1 byte + Changes size of data: No + Allow as a non-last filter: Yes + Allow as the last filter: No + + Preferred alignment: + Input data: 1 byte + Output data: Same as the original input data + + The Properties byte indicates the delta distance, which can be + 1-256 bytes backwards from the current byte: 0x00 indicates + distance of 1 byte and 0xFF distance of 256 bytes. + + +5.3.3.1.

Custom Filter IDs + + If a developer wants to use custom Filter IDs, he has two + choices. The first choice is to contact Lasse Collin and ask + him to allocate a range of IDs for the developer. + + The second choice is to generate a 40-bit random integer, + which the developer can use as his personal Developer ID. + To minimize the risk of collisions, Developer ID has to be + a randomly generated integer, not manually selected "hex word". + The following command, which works on many free operating + systems, can be used to generate Developer ID: + + dd if=/dev/urandom bs=5 count=1 | hexdump + + The developer can then use his Developer ID to create unique + (well, hopefully unique) Filter IDs. + + Bits Mask Description + 0-15 0x0000_0000_0000_FFFF Filter ID + 16-55 0x00FF_FFFF_FFFF_0000 Developer ID + 56-62 0x3F00_0000_0000_0000 Static prefix: 0x3F + + The resulting 63-bit integer will use 9 bytes of space when + stored using the encoding described in Section 1.2.

+.SH SYNOPSIS +.B lzmainfo +.RB [ \-\-help ] +.RB [ \-\-version ] +.RI [ file... ] +.SH DESCRIPTION +.B lzmainfo +shows information stored in the +.B .lzma +file header. +It reads the first 13 bytes from the specified +.IR file , +decodes the header, and prints it to standard output in human +readable format. +If no +.I files +are given or +.I file +is +.BR \- , +standard input is read. +.PP +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 +.B .lzma +format variant. +The amount of memory required to decompress the file is +a few dozen kilobytes plus the dictionary size. +.PP +.B lzmainfo +is included in XZ Utils primarily for +backward compatibility with LZMA Utils. +.SH "EXIT STATUS" +.TP +.B 0 +All is good. +.TP +.B 1 +An error occurred. +.SH BUGS +.B lzmainfo +uses +.B MB +while the correct suffix would be +.B MiB +(2^20 bytes). +This is to keep the output

+.br +.B lzcat +is equivalent to +.BR "xz \-\-format=lzma \-\-decompress \-\-stdout" . +.PP +When writing scripts that need to decompress files, +it is recommended to always use the name +.B xz +with appropriate arguments +.RB ( "xz \-d" +or +.BR "xz \-dc" ) +instead of the names +.B unxz +and +.BR xzcat . +. +.SH DESCRIPTION +.B xz +is a general-purpose data compression tool with +command line syntax similar to +.BR gzip (1) +and +.BR bzip2 (1). +The native file format is the +.B .xz +format, but the legacy +.B .lzma +format used by LZMA Utils and +raw compressed streams with no container format headers +are also supported. +.PP +.B xz +compresses or decompresses each +.I file +according to the selected operation mode. +If no +.I files +are given or +.I file +is +.BR \- , +.B xz +reads from standard input and writes the processed data +to standard output. +.B xz +will refuse (display an error and skip the +.IR file ) +to write compressed data to standard output if it is a terminal. +Similarly, +.B xz +will refuse to read compressed data +from standard input if it is a terminal. +.PP +Unless +.B \-\-stdout +is specified, +.I files +other than +.B \- +are written to a new file whose name is derived from the source +.I file +name: +.IP \(bu 3 +When compressing, the suffix of the target file format +.RB ( .xz +or +.BR .lzma ) +is appended to the source filename to get the target filename. +.IP \(bu 3 +When decompressing, the +.B .xz +or +.B .lzma +suffix is removed from the filename to get the target filename. +.B xz +also recognizes the suffixes +.B .txz +and +.BR .tlz , +and replaces them with the +.B .tar +suffix. +.PP +If the target file already exists, an error is displayed and the +.I file +is skipped. +.PP +Unless writing to standard output, +.B xz +will display a warning and skip the +.I file +if any of the following applies: +.IP \(bu 3 +.I File +is not a regular file. +Symbolic links are not followed, +and thus they are not considered to be regular files. +.IP \(bu 3 +.I File +has more than one hard link. +.IP \(bu 3 +.I File +has setuid, setgid, or sticky bit set. +.IP \(bu 3 +The operation mode is set to compress and the +.I file +already has a suffix of the target file format +.RB ( .xz +or +.B .txz +when compressing to the +.B .xz +format, and +.B .lzma +or +.B .tlz +when compressing to the +.B .lzma +format). +.IP \(bu 3 +The operation mode is set to decompress and the +.I file +doesn't have a suffix of any of the supported file formats +.RB ( .xz , +.BR .txz , +.BR .lzma , +or +.BR .tlz ). +.PP +After successfully compressing or decompressing the +.IR file , +.B xz +copies the owner, group, permissions, access time, +and modification time from the source +.I file +to the target file. +If copying the group fails, the permissions are modified +so that the target file doesn't become accessible to users +who didn't have permission to access the source +.IR file . +.B xz +doesn't support copying other metadata like access control lists +or extended attributes yet. +.PP +Once the target file has been successfully closed, the source +.I file +is removed unless +.B \-\-keep +was specified. +The source +.I file +is never removed if the output is written to standard output. +.PP +Sending +.B SIGINFO +or +.B SIGUSR1 +to the +.B xz +process makes it print progress information to standard error. +This has only limited use since when standard error +is a terminal, using +.B \-\-verbose +will display an automatically updating progress indicator. +. +.SS "Memory usage" +The memory usage of +.B xz +varies from a few hundred kilobytes to several gigabytes +depending on the compression settings. +The settings used when compressing a file determine +the memory requirements of the decompressor. +Typically the decompressor needs 5\ % to 20\ % of +the amount of memory that the compressor needed when +creating the file. +For example, decompressing a file created with +.B xz \-9 +currently requires 65\ MiB of memory. +Still, it is possible to have +.B .xz +files that require several gigabytes of memory to decompress. +.PP +Especially users of older systems may find +the possibility of very large memory usage annoying. +To prevent uncomfortable surprises, +.B xz +has a built-in memory usage limiter, which is disabled by default. +While some operating systems provide ways to limit +the memory usage of processes, relying on it +wasn't deemed to be flexible enough (e.g. using +.BR ulimit (1) +to limit virtual memory tends to cripple +.BR mmap (2)). +.PP +The memory usage limiter can be enabled with +the command line option \fB\-\-memlimit=\fIlimit\fR. +Often it is more convenient to enable the limiter +by default by setting the environment variable +.BR XZ_DEFAULTS , +e.g.\& +.BR XZ_DEFAULTS=\-\-memlimit=150MiB . +It is possible to set the limits separately +for compression and decompression +by using \fB\-\-memlimit\-compress=\fIlimit\fR and +\fB\-\-memlimit\-decompress=\fIlimit\fR. +Using these two options outside +.B XZ_DEFAULTS +is rarely useful because a single run of +.B xz +cannot do both compression and decompression and +.BI \-\-memlimit= limit +(or \fB\-M\fR \fIlimit\fR) +is shorter to type on the command line. +.PP +If the specified memory usage limit is exceeded when decompressing, +.B xz +will display an error and decompressing the file will fail. +If the limit is exceeded when compressing, +.B xz +will try to scale the settings down so that the limit +is no longer exceeded (except when using \fB\-\-format=raw\fR +or \fB\-\-no\-adjust\fR). +This way the operation won't fail unless the limit is very small. +The scaling of the settings is done in steps that don't +match the compression level presets, e.g. if the limit is +only slightly less than the amount required for +.BR "xz \-9" , +the settings will be scaled down only a little, +not all the way down to +.BR "xz \-8" . +. +.SS "Concatenation and padding with .xz files" +It is possible to concatenate +.B .xz +files as is. +.B xz +will decompress such files as if they were a single +.B .xz +file. +.PP +It is possible to insert padding between the concatenated parts +or after the last part. +The padding must consist of null bytes and the size +of the padding must be a multiple of four bytes. +This can be useful e.g. if the +.B .xz +file is stored on a medium that measures file sizes +in 512-byte blocks. +.PP +Concatenation and padding are not allowed with +.B .lzma +files or raw streams. +. +.SH OPTIONS +. +.SS "Integer suffixes and special values" +In most places where an integer argument is expected, +an optional suffix is supported to easily indicate large integers. +There must be no space between the integer and the suffix. +.TP +.B KiB +Multiply the integer by 1,024 (2^10). +.BR Ki , +.BR k , +.BR kB , +.BR K , +and +.B KB +are accepted as synonyms for +.BR KiB . +.TP +.B MiB +Multiply the

in the +.B .lzma +header. +LZMA Utils does that when compressing regular files. +The alternative is to mark that uncompressed size is unknown +and use end-of-payload marker to indicate +where the decompressor should stop. +LZMA Utils uses this method when uncompressed size isn't known, +which is the case for example in pipes. +.PP +.B xz +supports decompressing +.B .lzma +files with or without end-of-payload marker, but all +.B .lzma +files created by +.B xz +will use end-of-payload marker and have uncompressed size +marked as unknown in the +.B .lzma +header. +This may be a problem in some uncommon situations. +For example, a +.B .lzma +decompressor in an embedded device might work +only with files that have known uncompressed size. +If you hit this problem, you need to use LZMA Utils +or LZMA SDK to create +.B .lzma +files with known uncompressed size. +. +.SS "Unsupported .lzma files" +The +.B .lzma +format allows +.I lc +values up to 8, and +.I lp +values up to 4. +LZMA Utils can decompress files with any +.I lc +and +.IR lp , +but always creates files with +.B lc=3 +and +.BR lp=0 . +Creating files with other +.I lc +and +.I lp +is possible with +.B xz +and with LZMA SDK. +.PP +The implementation of the LZMA1 filter in liblzma +requires that the sum of +.I lc +and +.I lp +must not exceed 4. +Thus, +.B .lzma +files, which exceed this limitation, cannot be decompressed with +.BR xz . +.PP +LZMA Utils creates only +.B .lzma +files which have a dictionary size of +.RI "2^" n +(a power of 2) but accepts files with any dictionary size. +liblzma accepts only +.B .lzma +files which have a dictionary size of +.RI "2^" n +or +.RI "2^" n " + 2^(" n "\-1)." +This is to decrease false positives when detecting +.B .lzma +files. +.PP +These limitations shouldn't be a problem in practice, +since practically all +.B .lzma +files have been compressed with settings that liblzma will accept. +. +.SS "Trailing garbage" +When decompressing, +LZMA Utils silently ignore everything after the first +.B .lzma +stream. +In most situations, this is a bug. +This also means that LZMA Utils +don't support decompressing concatenated +.B .lzma +files. +.PP +If there is data left after the first +.B .lzma +stream, +.B xz +considers the file to be corrupt unless +.B \-\-single\-stream +was used. +This may break obscure scripts which have +assumed that trailing garbage is ignored. +. +.SH NOTES +. +.SS "Compressed output may vary" +The exact compressed output produced from +the same uncompressed input file +may vary between XZ Utils versions even if +compression options are identical. +This is because the encoder can be improved +(faster or better compression) +without affecting the file format. +The output can vary even between different +builds of the same XZ Utils version, +if different build options are used. +.PP +The above means that once +.B \-\-rsyncable +has been implemented, +the resulting files won't necessarily be rsyncable +unless both old and new files have been compressed +with the same xz version. +This problem can be fixed if a part of the encoder +implementation is frozen to keep rsyncable output +stable across xz versions. +. +.SS "Embedded .xz decompressors" +Embedded +.B .xz +decompressor implementations like XZ Embedded don't necessarily +support files created with integrity +.I check +types other than +.B none +and +.BR crc32 . +Since the default is +.BR \-\-check=crc64 , +you must use +.B \-\-check=none +or +.B \-\-check=crc32 +when creating files for embedded systems. +.PP +Outside embedded systems, all +.B .xz

xzdec +.RI [ option... ] +.RI [ file... ] +.br +.B lzmadec +.RI [ option... ] +.RI [ file... ] +.SH DESCRIPTION +.B xzdec +is a liblzma-based decompression-only tool for +.B .xz +(and only +.BR .xz ) +files. +.B xzdec +is intended to work as a drop-in replacement for +.BR xz (1) +in the most common situations where a script +has been written to use +.B "xz \-\-decompress \-\-stdout" +(and possibly a few other commonly used options) to decompress +.B .xz +files. +.B lzmadec +is identical to +.B xzdec +except that +.B lzmadec +supports +.B .lzma +files instead of +.B .xz +files. +.PP +To reduce the size of the executable, +.B xzdec +doesn't support multithreading or localization, +and doesn't read options from +.B XZ_DEFAULTS +and +.B XZ_OPT +environment variables. +.B xzdec +doesn't support displaying intermediate progress information: sending +.B SIGINFO +to +.B xzdec +does nothing, but sending +.B SIGUSR1 +terminates the process instead of displaying progress information. +.SH OPTIONS +.TP +.BR \-d ", " \-\-decompress ", " \-\-uncompress +Ignored for +.BR xz (1) +compatibility. +.B xzdec +supports only decompression. +.TP +.BR \-k ", " \-\-keep +Ignored for +.BR xz (1)

\-\-no-warn +Ignored for +.BR xz (1) +compatibility. +.B xzdec +never uses the exit status 2. +.TP +.BR \-h ", " \-\-help +Display a help message and exit successfully. +.TP +.BR \-V ", " \-\-version +Display the version number of +.B xzdec +and liblzma. +.SH "EXIT STATUS" +.TP +.B 0 +All was good. +.TP +.B 1 +An error occurred. +.PP +.B xzdec +doesn't have any warning messages like +.BR xz (1) +has, thus the exit status 2 is not used by +.BR xzdec . +.SH NOTES +Use +.BR xz (1) +instead of +.B xzdec +or +.B lzmadec +for normal everyday use. +.B xzdec +or +.B lzmadec +are meant only for situations where it is important to have +a smaller decompressor than the full-featured +.BR xz (1). +.PP +.B xzdec +and +.B 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 +.B .xz +decompressor, consider using XZ Embedded. +.SH "SEE ALSO" +.BR xz (1) +.PP +XZ Embedded: diff --git a/src/xzdec/xzdec.c b/src/xzdec/xzdec.c new file mode 100644 index 00000000..5cb7530a ---

Like + with the good files, these files must not require a lot of CPU time + or RAM before they get detected to be broken. + + +2. Descriptions of Individual Files + +2.1. Good Files + + good-0-empty.xz has one Stream with no Blocks. + + good-0pad-empty.xz has one Stream with no Blocks followed by + four-byte Stream Padding. + + good-0cat-empty.xz has two zero-Block Streams concatenated without + Stream Padding. + + good-0catpad-empty.xz has two zero-Block Streams concatenated with + four-byte Stream Padding between the Streams. + + good-1-check-none.xz has one Stream with one Block with two + uncompressed LZMA2 chunks and no integrity check. + + good-1-check-crc32.xz has one Stream with one Block with two + uncompressed LZMA2 chunks and CRC32 check. + + good-1-check-crc64.xz is like good-1-check-crc32.xz but with CRC64. + + good-1-check-sha256.xz is like good-1-check-crc32.xz but with + SHA256. + + good-2-lzma2.xz has one Stream with two Blocks with one uncompressed + LZMA2 chunk in each Block. + + good-1-block_header-1.xz has both Compressed Size and Uncompressed + Size in the Block Header. This has also four extra bytes of Header + Padding. + + good-1-block_header-2.xz has known Compressed Size. + + good-1-block_header-3.xz has known Uncompressed Size. + + good-1-delta-lzma2.tiff.xz is an image file that compresses + better with Delta+LZMA2 than with plain LZMA2. + + good-1-x86-lzma2.xz uses the x86 filter (BCJ) and LZMA2. The + uncompressed file is compress_prepared_bcj_x86 found from the tests + directory. + + good-1-sparc-lzma2.xz uses the SPARC filter and LZMA. The + uncompressed file is compress_prepared_bcj_sparc found from the tests + directory. + + good-1-lzma2-1.xz has two LZMA2 chunks, of which the second sets + new properties. + + good-1-lzma2-2.xz has two LZMA2 chunks, of which the second resets + the state without specifying new properties. + + good-1-lzma2-3.xz has two LZMA2 chunks, of which the first is + uncompressed and the second is LZMA. The first chunk resets dictionary + and the second sets new properties. + + good-1-lzma2-4.xz has three LZMA2 chunks: First is LZMA, second is + uncompressed with dictionary reset, and third is LZMA with new + properties but without dictionary reset. + + good-1-lzma2-5.xz has an empty LZMA2 stream with only the end of + payload marker. XZ Utils 5.0.1 and older incorrectly see this file + as corrupt. + + good-1-3delta-lzma2.xz has three Delta filters and LZMA2. + + +2.2. Unsupported Files + + unsupported-check.xz uses Check ID 0x02 which isn't supported by + the current version of the file format. It is implementation-defined + how this file handled (it may reject it, or decode it possibly with + a warning). + + unsupported-block_header.xz has a non-null byte in Header Padding, + which may indicate presence of a new unsupported field. + + unsupported-filter_flags-1.xz has unsupported Filter ID 0x7F. + + unsupported-filter_flags-2.xz specifies only Delta filter in the + List of Filter Flags, but Delta isn't allowed as the last filter in + the chain. It could be a little more correct to detect this file as + corrupt instead of unsupported, but saying it is unsupported is + simpler in case of liblzma. + + unsupported-filter_flags-3.xz specifies two LZMA2 filters in the + List of Filter Flags. LZMA2 is allowed only as the last filter in the + chain. It could be a little more correct to detect this file as + corrupt instead of unsupported, but saying it is unsupported is + simpler in case of liblzma. + + +2.3. Bad Files + + bad-0pad-empty.xz has one Stream with no Blocks followed by + five-byte Stream Padding. Stream Padding must be a multiple of four + bytes, thus this file is corrupt. + + bad-0catpad-empty.xz has two zero-Block Streams concatenated with + five-byte Stream Padding between the Streams. + + bad-0cat-alone.xz is good-0-empty.xz concatenated with an empty + LZMA_Alone file. + + bad-0cat-header_magic.xz is good-0cat-empty.xz but with one byte + wrong in the Header Magic Bytes field of the second Stream. liblzma + gives LZMA_DATA_ERROR for this. (LZMA_FORMAT_ERROR is used only if + the first Stream of a file has invalid Header Magic Bytes.) + + bad-0-header_magic.xz is good-0-empty.xz but with one byte wrong + in the Header Magic Bytes field. liblzma gives LZMA_FORMAT_ERROR for + this. + + bad-0-footer_magic.xz is good-0-empty.xz but with one byte wrong + in the Footer Magic Bytes field. liblzma gives LZMA_DATA_ERROR for + this. + + bad-0-empty-truncated.xz is good-0-empty.xz without the last byte + of the file. + + bad-0-nonempty_index.xz has no Blocks but Index claims that there is + one Block. + + bad-0-backward_size.xz has wrong Backward Size in Stream Footer. + + bad-1-stream_flags-1.xz has different Stream Flags in Stream Header + and Stream Footer. + + bad-1-stream_flags-2.xz has wrong CRC32 in Stream Header. + + bad-1-stream_flags-3.xz has wrong CRC32 in Stream Footer. + + bad-1-vli-1.xz has two-byte variable-length integer in the + Uncompressed Size field in Block Header while one-byte would be enough + for that value. It's important that the file gets rejected due to too + big integer encoding instead of due to Uncompressed Size not matching + the value stored in the Block Header. That is, the decoder must not + try to decode the Compressed Data field. + + bad-1-vli-2.xz has ten-byte variable-length integer as Uncompressed + Size in Block Header. It's important that the file gets rejected due + to too big integer encoding instead of due to Uncompressed Size not + matching the value stored in the Block Header. That is, the decoder + must not try to decode the Compressed Data field. + + bad-1-block_header-1.xz has Block Header that ends in the middle of + the Filter Flags field. + + bad-1-block_header-2.xz has Block Header that has Compressed Size and + Uncompressed Size but no List of Filter Flags field. + + bad-1-block_header-3.xz has wrong CRC32 in Block Header. + + bad-1-block_header-4.xz has too big Compressed Size in Block Header + (2^63 - 1 bytes while maximum is a little less, because the whole + Block must stay smaller than 2^63). It's important that the file + gets rejected due to invalid Compressed Size value; the decoder + must not try decoding the Compressed Data field. + + bad-1-block_header-5.xz has zero as Compressed Size in Block Header. + + bad-1-block_header-6.xz has corrupt Block Header which may crash + xz -lvv in XZ Utils 5.0.3 and earlier.

It is important that the + file gets rejected specifically due to Unpadded Size having an invalid + value. + + bad-2-compressed_data_padding.xz has non-null byte in the padding of + the Compressed Data field of the first Block. + + bad-1-check-crc32.xz has wrong Check (CRC32). + + bad-1-check-crc64.xz has wrong Check (CRC64). + + bad-1-check-sha256.xz has wrong Check (SHA-256). + + bad-1-lzma2-1.xz has LZMA2 stream whose first chunk (uncompressed) + doesn't reset the dictionary. + + bad-1-lzma2-2.xz has two LZMA2 chunks, of which the second chunk + indicates dictionary reset, but the LZMA compressed data tries to + repeat data from the previous chunk. + + bad-1-lzma2-3.xz sets new invalid properties (lc=8, lp=0, pb=0) in + the middle of Block. + + bad-1-lzma2-4.xz has two LZMA2 chunks, of which the first is + uncompressed and the second is LZMA.

The final + binary package will be standalone in sense that it will depend only + on DLLs that are included in all Windows installations. + + These instructions don't apply to Cygwin. XZ Utils can be built under + Cygwin in the same way as many other packages. + + These instructions don't apply to MinGW and MSYS developers either, + who may want to package XZ Utils for MinGW or MSYS distributions. + You know who you are, and will probably use quite different configure + options etc. than what is described here. + + +Installing the toolchain(s) +--------------------------- + + Some of the following is needed: + - MSYS is always needed to use the GNU Autotools based build system. + - MinGW builds 32-bit x86 binaries. + - 32-bit MinGW-w64 (I call it MingW-w32 here) builds 32-bit x86 + executables too. + - MinGW-w64 builds 64-bit x86-64 binaries. + + So you need to pick between MinGW and MinGW-w32 when building + 32-bit version. You don't need both. + + You might find 7-Zip handy when extracting + some files. The ready-made build script build.bash will also use + 7-Zip to create the distributable .zip and .7z files. + + I used the following directory structure but you can use whatever + you want. Just note that I will use these in my examples. Each of + these should have a subdirectory "bin": + + C:\devel\tools\msys + C:\devel\tools\mingw + C:\devel\tools\mingw-w32 + C:\devel\tools\mingw-w64 + + +Installing MSYS + + You can download MSYS from MinGW's Sourceforge page: + + http://sourceforge.net/projects/mingw/files/MSYS/Base/msys-core/ + + I recommend using MSYS 1.0.11 (MSYS-1.0.11.exe or + msysCORE-1.0.11-bin.tar.gz) because that package includes all the + required tools. At least some of the later versions include only + a subset and thus you would need to download the rest separately. + The old version will work fine for building XZ Utils. + + You can use either the .exe or .tar.gz package.

You can find the + latest version and full source code from . + + The parts of the XZ Utils source code, that are relevant to this + binary package, are in the public domain. XZ Utils have been built + for this package with MinGW-w64 and linked statically against its + runtime libraries.

You don't need an import library to link + against liblzma.dll, and for static linking, you don't need to + worry about the LZMA_API_STATIC macro. + + Note that the MinGW distribution includes liblzma. If you are + building packages that will be part of the MinGW distribution, you + probably should use the version of liblzma shipped in MinGW instead + of this package. + + +Microsoft Visual C++ + + To link against liblzma.dll, you need to create an import library + first. You need the "lib" command from MSVC and liblzma.def from + the "doc" directory of this package.

Alternatively, if having + a decompressor is enough, consider using XZ Embedded or LZMA SDK. + + When you plan to link against static liblzma, you need to tell + lzma.h to not use __declspec(dllimport) by defining the macro + LZMA_API_STATIC. You can do it either in the C/C++ code + + #define LZMA_API_STATIC + #include + + or by adding it to compiler options. + + +Other compilers + + If you are using some other compiler, see its documentation how to + create an import library (if it is needed).
