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.

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.

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.

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. But first, please read +. diff --git a/COPYING.LGPLv2.1 b/COPYING.LGPLv2.1 new file mode 100644 index 0000000..4362b49 --- /dev/null +++ b/COPYING.LGPLv2.1 @@ -0,0 +1,502 @@ + GNU LESSER GENERAL PUBLIC LICENSE + Version 2.1, February 1999 + + Copyright (C) 1991, 1999 Free Software Foundation, Inc. + 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + +[This is the first released version of the Lesser GPL. It also counts + as the successor of the GNU Library Public License, version 2, hence + the version number 2.1.] + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Lesser General Public License, applies to some +specially designated software packages--typically libraries--of the +Free Software Foundation and other authors who decide to use it. You +can use it too, but we suggest you first think carefully about whether +this license or the ordinary General Public License is the better +strategy to use in any particular case, based on the explanations below. + + When we speak of free software, we are referring to freedom of use, +not price. Our General Public Licenses are designed to make sure that +you have the freedom to distribute copies of free software (and charge +for this service if you wish); that you receive source code or can get +it if you want it; that you can change the software and use pieces of +it in new free programs; and that you are informed that you can do +these things. + + To protect your rights, we need to make restrictions that forbid +distributors to deny you these rights or to ask you to surrender these +rights. These restrictions translate to certain responsibilities for +you if you distribute copies of the library or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link other code with the library, you must provide +complete object files to the recipients, so that they can relink them +with the library after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + We protect your rights with a two-step method: (1) we copyright the +library, and (2) we offer you this license, which gives you legal +permission to copy, distribute and/or modify the library. + + To protect each distributor, we want to make it very clear that +there is no warranty for the free library. Also, if the library is +modified by someone else and passed on, the recipients should know +that what they have is not the original version, so that the original +author's reputation will not be affected by problems that might be +introduced by others. + + Finally, software patents pose a constant threat to the existence of +any free program. We wish to make sure that a company cannot +effectively restrict the users of a free program by obtaining a +restrictive license from a patent holder. Therefore, we insist that +any patent license obtained for a version of the library must be +consistent with the full freedom of use specified in this license. + + Most GNU software, including some libraries, is covered by the +ordinary GNU General Public License. This license, the GNU Lesser +General Public License, applies to certain designated libraries, and +is quite different from the ordinary General Public License. We use +this license for certain libraries in order to permit linking those +libraries into non-free programs. + + When a program is linked with a library, whether statically or using +a shared library, the combination of the two is legally speaking a +combined work, a derivative of the original library. The ordinary +General Public License therefore permits such linking only if the +entire combination fits its criteria of freedom. The Lesser General +Public License permits more lax criteria for linking other code with +the library. + + We call this license the "Lesser" General Public License because it +does Less to protect the user's freedom than the ordinary General +Public License. It also provides other free software developers Less +of an advantage over competing non-free programs. These disadvantages +are the reason we use the ordinary General Public License for many +libraries. However, the Lesser license provides advantages in certain +special circumstances. + + For example, on rare occasions, there may be a special need to +encourage the widest possible use of a certain library, so that it becomes +a de-facto standard. To achieve this, non-free programs must be +allowed to use the library. A more frequent case is that a free +library does the same job as widely used non-free libraries. In this +case, there is little to gain by limiting the free library to free +software only, so we use the Lesser General Public License. + + In other cases, permission to use a particular library in non-free +programs enables a greater number of people to use a large body of +free software. For example, permission to use the GNU C Library in +non-free programs enables many more people to use the whole GNU +operating system, as well as its variant, the GNU/Linux operating +system. + + Although the Lesser General Public License is Less protective of the +users' freedom, it does ensure that the user of a program that is +linked with the Library has the freedom and the wherewithal to run +that program using a modified version of the Library. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, whereas the latter must +be combined with the library in order to run. + + GNU LESSER GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library or other +program which contains a notice placed by the copyright holder or +other authorized party saying it may be distributed under the terms of +this Lesser General Public License (also called "this License"). +Each licensee is addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control compilation +and installation of the library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. + + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. + + 2. You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also combine or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (1) uses at run time a + copy of the library already present on the user's computer system, + rather than copying library functions into the executable, and (2) + will operate properly with a modified version of the library, if + the user installs one, as long as the modified version is + interface-compatible with the version that the work was made with. + + c) Accompany the work with a written offer, valid for at + least three years, to give the same user the materials + specified in Subsection 6a, above, for a charge no more + than the cost of performing this distribution. + + d) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + e) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the materials to be distributed need not include anything that is +normally distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies +the executable. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + + 9. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties with +this License. + + 11. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply, +and the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 12. If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License may add +an explicit geographical distribution limitation excluding those countries, +so that distribution is permitted only in or among countries not thus +excluded. In such case, this License incorporates the limitation as if +written in the body of this License. + + 13. The Free Software Foundation may publish revised and/or new +versions of the Lesser General Public License from time to time. +Such new versions will be similar in spirit to the present version, +but may differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Library +specifies a version number of this License which applies to it and +"any later version", you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation. If the Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. + + 14. If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +write to the author to ask for permission. For software which is +copyrighted by the Free Software Foundation, write to the Free +Software Foundation; we sometimes make exceptions for this. Our +decision will be guided by the two goals of preserving the free status +of all derivatives of our free software and of promoting the sharing +and reuse of software generally. + + NO WARRANTY + + 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR +OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY +KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE +IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE +LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME +THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN +WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY +AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU +FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR +CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE +LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING +RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A +FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF +SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH +DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Libraries + + If you develop a new library, and you want it to be of the greatest +possible use to the public, we recommend making it free software that +everyone can redistribute and change. You can do so by permitting +redistribution under these terms (or, alternatively, under the terms of the +ordinary General Public License). + + To apply these terms, attach the following notices to the library. It is +safest to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least the +"copyright" line and a pointer to where the full notice is found. + + + 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.

As of writing, + "clang -fsanitize=undefined" (Clang 15) diagnoses this. However, + I'm not aware of any compiler that would take advantage of this + when optimizing (Clang 15 included). It's good to avoid this anyway + since compilers might some day infer that pointer arithmetic implies + that the pointer is not NULL. That is, the following foo() would then + unconditionally return 0, even for foo(NULL, 0): + + void bar(char *a, char *b); + + int foo(char *a, size_t n) + { + bar(a, a + n); + return a == NULL; + } + + In contrast to C, C++ explicitly allows null pointer + 0. So if + the above is compiled as C++ then there is no undefined behavior + in the foo(NULL, 0) call. + + To me it seems that changing the C standard would be the sane + thing to do (just add one sentence) as it would ensure that a huge + amount of old code won't break in the future. Based on web searches + it seems that a large number of codebases (where null pointer + 0 + occurs) are being fixed instead to be future-proof in case compilers + will some day optimize based on it (like making the above foo(NULL, 0) + return 0) which in the worst case will cause security bugs. + + Some projects don't plan to change it. For example, gnulib and thus + many GNU tools currently require that null pointer + 0 is defined: + + https://lists.gnu.org/archive/html/bug-gnulib/2021-11/msg00000.html + + https://www.gnu.org/software/gnulib/manual/html_node/Other-portability-assumptions.html + + In XZ Utils null pointer + 0 issue should be fixed after this + commit. This adds a few if-statements and thus branches to avoid + null pointer + 0. These check for size > 0 instead of ptr != NULL + because this way bugs where size > 0 && ptr == NULL will likely + get caught quickly. None of them are in hot spots so it shouldn't + matter for performance. + + A little less readable version would be replacing + + ptr + offset + + with + + offset != 0 ? ptr + offset : ptr + + or creating a macro for it: + + #define my_ptr_add(ptr, offset) \ + ((offset) != 0 ? ((ptr) + (offset)) : (ptr)) + + Checking for offset != 0 instead of ptr != NULL allows GCC >= 8.1, + Clang >= 7, and Clang-based ICX to optimize it to the very same code + as ptr + offset.

After checking + the ABI changes it turned out that >= 5.2.0 ABI is backward + compatible with the threaded encoder functions from 5.1.2alpha + (but not vice versa as fixes and extensions to these functions + were made between 5.1.2alpha and 5.2.0). + + In RHEL/CentOS 7, XZ Utils 5.2.2 was patched with + xz-5.2.2-compat-libs.patch to modify liblzma.map: + + - XZ_5.1.2alpha was added with lzma_stream_encoder_mt and + lzma_stream_encoder_mt_memusage. This matched XZ Utils 5.1.2alpha. + + - XZ_5.2 was replaced with XZ_5.2.2. It is clear that this was + an error; the intention was to keep using XZ_5.2 (XZ_5.2.2 + has never been used in XZ Utils). So XZ_5.2.2 lists all + symbols that were listed under XZ_5.2 before the patch. + lzma_stream_encoder_mt and _mt_memusage are included too so + they are listed both here and under XZ_5.1.2alpha. + + The patch didn't add any __asm__(".symver ...") lines to the .c + files. Thus the resulting liblzma.so exports the threaded encoder + functions under XZ_5.1.2alpha only. Listing the two functions + also under XZ_5.2.2 in liblzma.map has no effect without + matching .symver lines. + + The lack of XZ_5.2 in RHEL/CentOS 7 means that binaries linked + against unpatched XZ Utils 5.2.x won't run on RHEL/CentOS 7. + This is unfortunate but this alone isn't too bad as the problem + is contained within RHEL/CentOS 7 and doesn't affect users + of other distributions. It could also be fixed internally in + RHEL/CentOS 7. + + The second problem is more serious: In XZ Utils 5.2.2 the API + headers don't have #ifdef LZMA_UNSTABLE for obvious reasons. + This is true in RHEL/CentOS 7 version too. Thus now programs + using new APIs can be compiled without an extra #define. However, + the programs end up depending on symbol version XZ_5.1.2alpha + (and possibly also XZ_5.2.2) instead of XZ_5.2 as they would + with an unpatched XZ Utils 5.2.2. This means that such binaries + won't run on other distributions shipping XZ Utils >= 5.2.0 as + they don't provide XZ_5.1.2alpha or XZ_5.2.2; they only provide + XZ_5.2 (and XZ_5.0). (This includes RHEL/CentOS 8 as the patch + luckily isn't included there anymore with XZ Utils 5.2.4.) + + Binaries built by RHEL/CentOS 7 users get distributed and then + people wonder why they don't run on some other distribution. + Seems that people have found out about the patch and been copying + it to some build scripts, seemingly curing the symptoms but + actually spreading the illness further and outside RHEL/CentOS 7. + + The ill patch seems to be from late 2016 (RHEL 7.3) and in 2017 it + had spread at least to EasyBuild. I heard about the events only + recently. :-( + + This commit splits liblzma.map into two versions: one for + GNU/Linux and another for other OSes that can use symbol versioning + (FreeBSD, Solaris, maybe others). The Linux-specific file and the + matching additions to .c files add full compatibility with binaries + that have been built against a RHEL/CentOS-patched liblzma. Builds + for OSes other than GNU/Linux won't get the vaccine as they should + be immune to the problem (I really hope that no build script uses + the RHEL/CentOS 7 patch outside GNU/Linux). + + The RHEL/CentOS compatibility symbols XZ_5.1.2alpha and XZ_5.2.2 + are intentionally put *after* XZ_5.2 in liblzma_linux.map. This way + if one forgets to #define HAVE_SYMBOL_VERSIONS_LINUX when building, + the resulting liblzma.so.5 will have lzma_stream_encoder_mt@@XZ_5.2 + since XZ_5.2 {...} is the first one that lists that function. + Without HAVE_SYMBOL_VERSIONS_LINUX @XZ_5.1.2alpha and @XZ_5.2.2 + will be missing but that's still a minor problem compared to + only having lzma_stream_encoder_mt@@XZ_5.1.2alpha! + + The "local: *;" line was moved to XZ_5.0 so that it doesn't need + to be moved around. It doesn't matter where it is put. + + Having two similar liblzma_*.map files is a bit silly as it is, + at least for now, easily possible to generate the generic one + from the Linux-specific file. But that adds extra steps and + increases the risk of mistakes when supporting more than one + build system. So I rather maintain two files in parallel and let + validate_map.sh check that they are in sync when "make mydist" + is run. + + This adds .symver lines for lzma_stream_encoder_mt@XZ_5.2.2 and + lzma_stream_encoder_mt_memusage@XZ_5.2.2 even though these + weren't exported by RHEL/CentOS 7 (only @@XZ_5.1.2alpha was + for these two). I added these anyway because someone might + misunderstand the RHEL/CentOS 7 patch and think that @XZ_5.2.2 + (@@XZ_5.2.2) versions were exported too. + + At glance one could suggest using __typeof__ to copy the function + prototypes when making aliases. However, this doesn't work trivially + because __typeof__ won't copy attributes (lzma_nothrow, lzma_pure) + and it won't change symbol visibility from hidden to default (done + by LZMA_API()). Attributes could be copied with __copy__ attribute + but that needs GCC 9 and a fallback method would be needed anyway. + + This uses __symver__ attribute with GCC >= 10 and + __asm__(".symver ...") with everything else. The attribute method + is required for LTO (-flto) support with GCC. Using -flto with + GCC older than 10 is now broken on GNU/Linux and will not be fixed + (can silently result in a broken liblzma build that has dangerously + incorrect symbol versions).

So only the last line or two get escaped. + + One way to fix this would be to read all lines into the pattern + space first. However, the included fix is even simpler: All lines + except the last line get a backslash appended at the end. To ensure + that shell command substitution doesn't eat a possible trailing + newline, a colon is appended to the filename before escaping. + The colon is later used to separate the filename from the grep + output so it is fine to add it here instead of a few lines later. + + The old code also wasn't POSIX compliant as it used \n in the + replacement section of the s-command.

Then both spellings work. + + To make the behavior consistent between case sensitive and + insensitive file systems, the config and related files are + renamed from liblzmaConfig.cmake to liblzma-config.cmake style. + With this style CMake looks for lowercase version of the package + name so find_package(LiBLzmA 5.2.5 REQUIRED CONFIG) will work + to find our config file. + + There are other differences between our config file and + FindLibLZMA so it's still possible that things break for + reasons other than the spelling of the target name. Hopefully + those situations aren't too common. + + When the config file is available, it should always give as good or + better results as FindLibLZMA so this commit doesn't affect the + recommendation to use find_package(liblzma 5.2.5 REQUIRED CONFIG) + which explicitly avoids FindLibLZMA. + + Thanks to Markus Rickert. + + CMakeLists.txt | 21 +++++++++++++-------- + 1 file changed, 13 insertions(+), 8 deletions(-) + +commit 5b7bc1b8ae766a76710ca1b99f909cf52c697f05 +Author: Lasse Collin +Date: 2021-01-29 21:19:43 +0200 + + Update THANKS. + + THANKS | 1 + + 1 file changed, 1 insertion(+) + +commit 6c6f0db340dcb8bb424411cedba713405d55f6b8 +Author: Lasse Collin +Date: 2021-01-29 21:19:08 +0200 + + liblzma: Fix unitialized variable. + + This was introduced two weeks ago in the commit + 625f4c7c99b2fcc4db9e7ab2deb4884790e2e17c. + + Thanks to Nathan Moinvaziri. + + src/liblzma/lzma/lzma_encoder.c | 1 + + 1 file changed, 1 insertion(+) + +commit bb1d5c1fdd30550d4221ecd336e0be1206132a5c +Author: Lasse Collin +Date: 2021-01-24 22:32:41 +0200 + + Tests: Add bad-1-lzma2-10.xz and also modify -9.xz. + + tests/files/README | 11 +++++++++-- + tests/files/bad-1-lzma2-10.xz | Bin 0 -> 60 bytes + tests/files/bad-1-lzma2-9.xz | Bin 72 -> 72 bytes + 3 files changed, 9 insertions(+), 2 deletions(-) + +commit 6b8abc84a5469792e0355d0bfc0784d41cfdfef7 +Author: Lasse Collin +Date: 2021-01-24 19:22:35 +0200 + + liblzma: Fix a wrong comment in stream_encoder_mt.c. + + src/liblzma/common/stream_encoder_mt.c | 10 +++++++--- + 1 file changed, 7 insertions(+), 3 deletions(-) + +commit 939fc5ed654aac25fe0c8684b2df8dbeadb2de1e +Author: Lasse Collin +Date: 2021-01-24 18:51:51 +0200 + + Tests: Add bad-1-lzma2-9.xz. + + tests/files/README | 4 ++++ + tests/files/bad-1-lzma2-9.xz | Bin 0 -> 72 bytes + 2 files changed, 4 insertions(+) + +commit fdd30032f8531ac89519b48c21d810ecf06825f6 +Author: Lasse Collin +Date: 2021-01-24 17:02:00 +0200 + + Tests: Add bad-1-check-crc32-2.xz. + + tests/files/README | 7 +++++++ + tests/files/bad-1-check-crc32-2.xz | Bin 0 -> 72 bytes + 2 files changed, 7 insertions(+) + +commit db465419ae26ec7fb9b9472183911ff521620c77 +Author: Lasse Collin +Date: 2021-01-17 19:20:50 +0200 + + liblzma: In EROFS LZMA decoder, verify that comp_size matches at the end. + + When the uncompressed size is known to be exact, after decompressing + the stream exactly comp_size bytes of input must have been consumed. + This is a minor improvement to error detection. + + src/liblzma/common/erofs_decoder.c | 7 ++++++- + 1 file changed, 6 insertions(+), 1 deletion(-) + +commit 774cc0118ba2496581cb2621505a04bb6598cc75 +Author: Lasse Collin +Date: 2021-01-17 18:53:34 +0200 + + liblzma: Make EROFS LZMA decoder work when exact uncomp_size isn't known. + + The caller must still not specify an uncompressed size bigger + than the actual uncompressed size. + + As a downside, this now needs the exact compressed size. + + src/liblzma/api/lzma/container.h | 23 ++++++++--- + src/liblzma/common/erofs_decoder.c | 80 ++++++++++++++++++++++++++++++++++---- + 2 files changed, 91 insertions(+), 12 deletions(-) + +commit 421b0aa352da244075db10205cf33712f91b9835 +Author: Lasse Collin +Date: 2021-01-14 20:57:11 +0200 + + liblzma: Fix missing normalization in rc_encode_dummy(). + + Without this fix it could attempt to create too much output. + + src/liblzma/rangecoder/range_encoder.h | 7 ++++++- + 1 file changed, 6 insertions(+), 1 deletion(-) + +commit 601ec0311e769fc704daaaa7dac0ca840aff080e +Author: Lasse Collin +Date: 2021-01-14 20:07:01 +0200 + + liblzma: Add EROFS LZMA encoder and decoder. + + Right now this is just a planned extra-compact format for use + in the EROFS file system in Linux.

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 5.4 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). Nowadays + /usr/xpg4/bin is added to the script PATH by default on Solaris + (see --enable-path-for-scripts=PREFIX in section 2), but old xz + releases needed extra steps. See sections 5.5 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 5.1 in + this file (pass also ac_cv_prog_cc_c99= to configure). + + +1.2.7. Windows + + If it is enough to build liblzma (no command line tools): + + - There is CMake support. It should be good enough to build + static liblzma or liblzma.dll with Visual Studio. The CMake + support may work with MinGW or MinGW-w64. Read the comment + in the beginning of CMakeLists.txt before running CMake! + + - There are Visual Studio project files under the "windows" + directory. See windows/INSTALL-MSVC.txt. In the future the + project files will be removed when CMake support is good + enough. Thus, please test the CMake version and help fix + possible issues. + + To build also the command line tools: + + - 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". + + 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 a Makefile in the "dos" directory to build XZ Utils on + DOS using DJGPP. Support for long file names (LFN) is needed at + build time but the resulting xz.exe works without LFN support too. + See dos/INSTALL.txt and dos/README.txt for more information. + + +1.2.9. z/OS + + To build XZ Utils on z/OS UNIX System Services using xlc, pass + these options to the configure script: CC='xlc -qhaltonmsg=CCN3296' + CPPFLAS='-D_UNIX03_THREADS -D_XOPEN_SOURCE=600'. The first makes + xlc throw an error if a header file is missing, which is required + to make the tests in configure work. The CPPFLAGS are needed to + get pthread support (some other CPPFLAGS may work too; if there + are problems, try -D_UNIX95_THREADS instead of -D_UNIX03_THREADS). + + test_scripts.sh in "make check" will fail even if the scripts + actually work because the test data includes compressed files + with US-ASCII text. + + No other tests should fail. If test_files.sh fails, check that + the included .xz test files weren't affected by EBCDIC conversion. + + XZ Utils doesn't have code to detect the amount of physical RAM and + number of CPU cores on z/OS. + + +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. + + --enable-external-sha256 + Try to use SHA-256 code from the operating system libc + or similar base system libraries. This doesn't try to + use OpenSSL or libgcrypt or such libraries. + + The reasons to use this option: + + - It makes liblzma slightly smaller. + + - It might improve SHA-256 speed if the implementation + in the operating is very good (but see below). + + External SHA-256 is disabled by default for two reasons: + + - On some operating systems the symbol names of the + SHA-256 functions conflict with OpenSSL's libcrypto. + This causes weird problems such as decompression + errors if an application is linked against both + liblzma and libcrypto. This problem affects at least + FreeBSD 10 and older and MINIX 3.3.0 and older, but + other OSes that provide a function "SHA256_Init" might + also be affected. FreeBSD 11 has the problem fixed. + NetBSD had the problem but it was fixed it in 2009 + already. OpenBSD uses "SHA256Init" and thus never had + a conflict with libcrypto. + + - The SHA-256 code in liblzma is faster than the SHA-256 + code provided by some operating systems. If you are + curious, build two copies of xz (internal and external + SHA-256) and compare the decompression (xz --test) + times: + + dd if=/dev/zero bs=1024k count=1024 \ + | xz -v -0 -Csha256 > foo.xz + time xz --test foo.xz + + --disable-microlzma + Don't build MicroLZMA encoder and decoder. This omits + lzma_microlzma_encoder() and lzma_microlzma_decoder() + API functions from liblzma. These functions are needed + by specific applications only. They were written for + erofs-utils but they may be used by others too. + + --disable-lzip-decoder + Disable decompression support for .lz (lzip) files. + This omits the API function lzma_lzip_decoder() from + liblzma and .lz support from the xz tool. + + --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. + + --disable-clmul-crc + Disable the use carryless multiplication for CRC + calculation even if compiler support for it is detected. + The code uses runtime detection of SSSE3, SSE4.1, and + CLMUL instructions on x86. On 32-bit x86 this currently + is used only if --disable-assembler is used (this might + be fixed in the future). The code works on E2K too. + + If using compiler options that unconditionally allow the + required extensions (-msse4.1 -mpclmul) then runtime + detection isn't used and the generic code is omitted. + + --enable-unaligned-access + Allow liblzma to use unaligned memory access for 16-bit, + 32-bit, and 64-bit loads and stores. This should be + enabled only when the hardware supports this, that is, + 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, + big endian PowerPC, some ARM, and some ARM64 systems. + + --enable-unsafe-type-punning + This enables use of code like + + uint8_t *buf8 = ...; + *(uint32_t *)buf8 = ...; + + which violates strict aliasing rules and may result + in broken code. There should be no need to use this + option with recent GCC or Clang versions on any + arch as just as fast code can be generated in a safe + way too (using __builtin_assume_aligned + memcpy). + + However, this option might improve performance in some + other cases, especially with old compilers (for example, + GCC 3 and early 4.x on x86, GCC < 6 on ARMv6 and ARMv7). + + --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. Unless the compiler + supports __attribute__((__constructor__)), + 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 + and the compiler doesn't support + __attribute__((__constructor__)), 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-sandbox=METHOD + There is limited sandboxing support in the xz tool. If + built with sandbox support, it's used automatically when + (de)compressing exactly one file to standard output and + the options --files or --files0 weren't used. This is a + common use case, for example, (de)compressing .tar.xz + files via GNU tar. The sandbox is also used for + single-file `xz --test' or `xz --list'. + + Supported METHODs: + + auto Look for a supported sandboxing method + and use it if found. If no method is + found, then sandboxing isn't used. + This is the default. + + no Disable sandboxing support. + + capsicum + Use Capsicum (FreeBSD >= 10) for + sandboxing. If no Capsicum support + is found, configure will give an error. + + pledge Use pledge(2) (OpenBSD >= 5.9) for + sandboxing. If pledge(2) isn't found, + configure will give an error. + + --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. + + --enable-path-for-scripts=PREFIX + If PREFIX isn't empty, PATH=PREFIX:$PATH will be set in + the beginning of the scripts (xzgrep and others). + The default is empty except on Solaris the default is + /usr/xpg4/bin. + + This can be useful if the default PATH doesn't contain + modern POSIX tools (as can be the case on Solaris) or if + one wants to ensure that the correct xz binary is in the + PATH for the scripts. Note that the latter use can break + "make check" if the prefixed PATH causes a wrong xz binary + (other than the one that was just built) to be used. + + Older xz releases support a different method for setting + the PATH for the scripts. It is described in section 3.2 + and is supported in this xz version too. + + +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. + For example, 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 method described below is supported by older xz releases. + It is supported by the current version too, but the newer + --enable-path-for-scripts=PREFIX described in section 2 may be + more convenient. + + The scripts assume that the required tools (standard POSIX utilities, + mktemp, and xz) are in PATH; the scripts don't set the PATH themselves + (except as described for --enable-path-for-scripts=PREFIX). 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. Tests +-------- + + The test framework can be built and run by executing "make check" in + the build directory. The tests are a mix of executables and POSIX + shell scripts (sh). All tests should pass if the default configuration + is used. Disabling features through the configure options may cause + some tests to be skipped. If any tests do not pass, see section 5.5. + + +4.1. Testing in parallel + + The tests can be run in parallel using the "-j" make option on systems + that support it. For instance, "make -j4 check" will run up to four + tests simultaneously. + + +4.2. Cross compiling + + The tests can be built without running them: + + make check TESTS= + + The TESTS variable is the list of tests you wish to run. Leaving it + empty will compile the tests without running any. + + If the tests are copied to a target machine to execute, the test data + files in the directory tests/files must also be copied. The tests + search for the data files using the environment variable $srcdir, + expecting to find the data files under $srcdir/files/. If $srcdir + isn't set then it defaults to the current directory. + + The shell script tests can be copied from the source directory to the + target machine to execute. In addition to the test files, these tests + will expect the following relative file paths to execute properly: + + ./create_compress_files + ../config.h + ../src/xz/xz + ../src/xzdec/xzdec + ../src/scripts/xzdiff + ../src/scripts/xzgrep + + +5. Troubleshooting +------------------ + +5.1. "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. + + +5.2. "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. + + +5.3. 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). + + +5.4. 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. + + +5.5. "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. For possible + fixes, see --enable-path-for-scripts=PREFIX in section 2 and the + older alternative method described in section 3.2 of this file. + + If tests other than test_scripts.sh fail, a likely reason is that + libtool links the test programs against an installed version of + liblzma instead of the version that was just built. This is + obviously a bug which seems to happen on some platforms. + A workaround is to uninstall the old liblzma versions first. + + If the problem isn't any of those described above, then it's likely + a bug in XZ Utils or in the compiler. See the platform-specific + notes in this file for possible known problems. Please report + a bug if you cannot solve the problem. See README for contact + information. + + +5.6. liblzma.so (or similar) not found when running xz + + If you installed the package with "make install" and get an error + about liblzma.so (or a similarly named file) being missing, try + running "ldconfig" to update the run-time linker cache (if your + operating system has such a command). + diff --git a/INSTALL.generic b/INSTALL.generic new file mode 100644 index 0000000..8865734 --- /dev/null +++ b/INSTALL.generic @@ -0,0 +1,368 @@ +Installation Instructions +************************* + + Copyright (C) 1994-1996, 1999-2002, 2004-2016 Free Software +Foundation, Inc. + + Copying and distribution of this file, with or without modification, +are permitted in any medium without royalty provided the copyright +notice and this notice are preserved.

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. + + HP-UX 'make' updates targets which have the same time stamps as their +prerequisites, which makes it generally unusable when shipped generated +files such as 'configure' are involved. Use GNU 'make' instead. + + 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 limitation. Until the limitation is lifted, you can use this +workaround: + + CONFIG_SHELL=/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 0000000..f562f90 --- /dev/null +++ b/Makefile.am @@ -0,0 +1,134 @@ +## +## 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 = $(docdir)/examples_old +dist_examplesold_DATA = \ + doc/examples_old/xz_pipe_comp.c \ + doc/examples_old/xz_pipe_decomp.c + +# Install the Doxygen generated documentation if they were built. +install-data-local: + if test -d "$(srcdir)/doc/api" ;

It uses 16-byte-aligned reads + which can extend past the bounds of the input buffer and + inherently trigger address sanitization errors. This isn't + a bug. + + - Fixed an assertion failure that could be triggered by a large + unpadded_size argument. It was verified that there was no + other bug than the assertion failure. + + - Fixed a bug that prevented building with Windows Vista + threading when __attribute__((__constructor__)) is not + supported. + + * xz now properly handles special files such as "con" or "nul" on + Windows. Before this fix, the following wrote "foo" to the + console and deleted the input file "con_xz": + + echo foo | xz > con_xz + xz --suffix=_xz --decompress con_xz + + * Build systems: + + - Allow builds with Windows win95 threading and small mode when + __attribute__((__constructor__)) is supported. + + - Added a new line to liblzma.pc for MSYS2 (Windows): + + Cflags.private: -DLZMA_API_STATIC + + When compiling code that will link against static liblzma, + the LZMA_API_STATIC macro needs to be defined on Windows. + + - CMake specific changes: + + * Fixed a bug that allowed CLOCK_MONOTONIC to be used even + if the check for it failed. + + * Fixed a bug where configuring CMake multiple times + resulted in HAVE_CLOCK_GETTIME and HAVE_CLOCK_MONOTONIC + not being set. + + * Fixed the build with MinGW-w64-based Clang/LLVM 17. + llvm-windres now has more accurate GNU windres emulation + so the GNU windres workaround from 5.4.1 is needed with + llvm-windres version 17 too. + + * The import library on Windows is now properly named + "liblzma.dll.a" instead of "libliblzma.dll.a" + + * Fixed a bug causing the Ninja Generator to fail on + UNIX-like systems. This bug was introduced in 5.4.0. + + * Added a new option to disable CLMUL CRC64. + + * A module-definition (.def) file is now created when + building liblzma.dll with MinGW-w64. + + * The pkg-config liblzma.pc file is now installed on all + builds except when using MSVC on Windows. + + * Added large file support by default for platforms that + need it to handle files larger than 2 GiB. This includes + MinGW-w64, even 64-bit builds. + + * Small fixes and improvements to the tests. + + * Updated translations: Chinese (simplified) and Esperanto. + + +5.4.4 (2023-08-02) + + * liblzma and xzdec can now build against WASI SDK when threading + support is disabled. xz and tests don't build yet. + + * CMake: + + - Fixed a bug preventing other projects from including liblzma + multiple times using find_package(). + + - Don't create broken symlinks in Cygwin and MSYS2 unless + supported by the environment. This prevented building for the + default MSYS2 environment. The problem was introduced in + xz 5.4.0. + + * Documentation: + + - Small improvements to man pages. + + - Small improvements and typo fixes for liblzma API + documentation. + + * Tests: + + - Added a new section to INSTALL to describe basic test usage + and address recent questions about building the tests when + cross compiling. + + - Small fixes and improvements to the tests. + + * Translations: + + - Fixed a mistake that caused one of the error messages to not + be translated. This only affected versions 5.4.2 and 5.4.3. + + - Updated the Chinese (simplified), Croatian, Esperanto, German, + Korean, Polish, Romanian, Spanish, Swedish, Ukrainian, and + Vietnamese translations. + + - Updated the German, Korean, Romanian, and Ukrainian man page + translations. + + +5.4.3 (2023-05-04) + + * All fixes from 5.2.12 + + * Features in the CMake build can now be disabled as CMake cache + variables, similar to the Autotools build. + + * Minor update to the Croatian translation. + + +5.4.2 (2023-03-18) + + * All fixes from 5.2.11 that were not included in 5.4.1. + + * If xz is built with support for the Capsicum sandbox but running + in an environment that doesn't support Capsicum, xz now runs + normally without sandboxing instead of exiting with an error. + + * liblzma: + + - Documentation was updated to improve the style, consistency, + and completeness of the liblzma API headers. + + - The Doxygen-generated HTML documentation for the liblzma API + header files is now included in the source release and is + installed as part of "make install". All JavaScript is + removed to simplify license compliance and to reduce the + install size. + + - Fixed a minor bug in lzma_str_from_filters() that produced + too many filters in the output string instead of reporting + an error if the input array had more than four filters. This + bug did not affect xz. + + * Build systems: + + - autogen.sh now invokes the doxygen tool via the new wrapper + script doxygen/update-doxygen, unless the command line option + --no-doxygen is used. + + - Added microlzma_encoder.c and microlzma_decoder.c to the + VS project files for Windows and to the CMake build. These + should have been included in 5.3.2alpha. + + * Tests: + + - Added a test to the CMake build that was forgotten in the + previous release. + + - Added and refactored a few tests. + + * Translations: + + - Updated the Brazilian Portuguese translation. + + - Added Brazilian Portuguese man page translation. + + +5.4.1 (2023-01-11) + + * liblzma: + + - Fixed the return value of lzma_microlzma_encoder() if the + LZMA options lc/lp/pb are invalid. Invalid lc/lp/pb options + made the function return LZMA_STREAM_END without encoding + anything instead of returning LZMA_OPTIONS_ERROR. + + - Windows / Visual Studio: Workaround a possible compiler bug + when targeting 32-bit x86 and compiling the CLMUL version of + the CRC64 code. The CLMUL code isn't enabled by the Windows + project files but it is in the CMake-based builds. + + * Build systems: + + - Windows-specific CMake changes: + + * Don't try to enable CLMUL CRC64 code if _mm_set_epi64x() + isn't available. This fixes CMake-based build with Visual + Studio 2013. + + * Created a workaround for a build failure with windres + from GNU binutils. It is used only when the C compiler + is GCC (not Clang). The workaround is incompatible + with llvm-windres, resulting in "XZx20Utils" instead + of "XZ Utils" in the resource file, but without the + workaround llvm-windres works correctly. See the + comment in CMakeLists.txt for details. + + * Included the resource files in the xz and xzdec build + rules. Building the command line tools is still + experimental but possible with MinGW-w64. + + - Visual Studio: Added stream_decoder_mt.c to the project + files. Now the threaded decompressor lzma_stream_decoder_mt() + gets built. CMake-based build wasn't affected. + + - Updated windows/INSTALL-MSVC.txt to mention that CMake-based + build is now the preferred method with Visual Studio. The + project files will probably be removed after 5.4.x releases. + + - Changes to #defines in config.h: + + * HAVE_DECL_CLOCK_MONOTONIC was replaced by + HAVE_CLOCK_MONOTONIC. The old macro was always defined + in configure-generated config.h to either 0 or 1. The + new macro is defined (to 1) only if the declaration of + CLOCK_MONOTONIC is available. This matches the way most + other config.h macros work and makes things simpler with + other build systems. + + * HAVE_DECL_PROGRAM_INVOCATION_NAME was replaced by + HAVE_PROGRAM_INVOCATION_NAME for the same reason. + + * Tests: + + - Fixed test script compatibility with ancient /bin/sh + versions. Now the five test_compress_* tests should + no longer fail on Solaris 10. + + - Added and refactored a few tests. + + * Translations: + + - Updated the Catalan and Esperanto translations. + + - Added Korean and Ukrainian man page translations. + + +5.4.0 (2022-12-13) + + This bumps the minor version of liblzma because new features were + added. The API and ABI are still backward compatible with liblzma + 5.2.x and 5.0.x. + + Since 5.3.5beta: + + * All fixes from 5.2.10. + + * The ARM64 filter is now stable. The xz option is now --arm64. + Decompression requires XZ Utils 5.4.0. In the future the ARM64 + filter will be supported by XZ for Java, XZ Embedded (including + the version in Linux), LZMA SDK, and 7-Zip. + + * Translations: + + - Updated Catalan, Croatian, German, Romanian, and Turkish + translations. + + - Updated German man page translations. + + - Added Romanian man page translations. + + Summary of new features added in the 5.3.x development releases: + + * liblzma: + + - Added threaded .xz decompressor lzma_stream_decoder_mt(). + It can use multiple threads with .xz files that have multiple + Blocks with size information in Block Headers. The threaded + encoder in xz has always created such files. + + Single-threaded encoder cannot store the size information in + Block Headers even if one used LZMA_FULL_FLUSH to create + multiple Blocks, so this threaded decoder cannot use multiple + threads with such files. + + If there are multiple Streams (concatenated .xz files), one + Stream will be decompressed completely before starting the + next Stream. + + - A new decoder flag LZMA_FAIL_FAST was added. It makes the + threaded decompressor report errors soon instead of first + flushing all pending data before the error location. + + - New Filter IDs: + * LZMA_FILTER_ARM64 is for ARM64 binaries. + * LZMA_FILTER_LZMA1EXT is for raw LZMA1 streams that don't + necessarily use the end marker. + + - Added lzma_str_to_filters(), lzma_str_from_filters(), and + lzma_str_list_filters() to convert a preset or a filter chain + string to a lzma_filter[] and vice versa. These should make + it easier to write applications that allow users to specify + custom compression options. + + - Added lzma_filters_free() which can be convenient for freeing + the filter options in a filter chain (an array of lzma_filter + structures). + + - lzma_file_info_decoder() to makes it a little easier to get + the Index field from .xz files. This helps in getting the + uncompressed file size but an easy-to-use random access + API is still missing which has existed in XZ for Java for + a long time. + + - Added lzma_microlzma_encoder() and lzma_microlzma_decoder(). + It is used by erofs-utils and may be used by others too. + + The MicroLZMA format is a raw LZMA stream (without end marker) + whose first byte (always 0x00) has been replaced with + bitwise-negation of the LZMA properties (lc/lp/pb). It was + created for use in EROFS but may be used in other contexts + as well where it is important to avoid wasting bytes for + stream headers or footers. The format is also supported by + XZ Embedded (the XZ Embedded version in Linux got MicroLZMA + support in Linux 5.16). + + The MicroLZMA encoder API in liblzma can compress into a + fixed-sized output buffer so that as much data is compressed + as can be fit into the buffer while still creating a valid + MicroLZMA stream. This is needed for EROFS. + + - Added lzma_lzip_decoder() to decompress the .lz (lzip) file + format version 0 and the original unextended version 1 files. + Also lzma_auto_decoder() supports .lz files. + + - lzma_filters_update() can now be used with the multi-threaded + encoder (lzma_stream_encoder_mt()) to change the filter chain + after LZMA_FULL_BARRIER or LZMA_FULL_FLUSH. + + - In lzma_options_lzma, allow nice_len = 2 and 3 with the match + finders that require at least 3 or 4. Now it is internally + rounded up if needed. + + - CLMUL-based CRC64 on x86-64 and E2K with runtime processor + detection. On 32-bit x86 it currently isn't available unless + --disable-assembler is used which can make the non-CLMUL + CRC64 slower; this might be fixed in the future. + + - Building with --disable-threads --enable-small + is now thread-safe if the compiler supports + __attribute__((__constructor__)). + + * xz: + + - Using -T0 (--threads=0) will now use multi-threaded encoder + even on a single-core system. This is to ensure that output + from the same xz binary is identical on both single-core and + multi-core systems. + + - --threads=+1 or -T+1 is now a way to put xz into + multi-threaded mode while using only one worker thread. + The + is ignored if the number is not 1. + + - A default soft memory usage limit is now used for compression + when -T0 is used and no explicit limit has been specified. + This soft limit is used to restrict the number of threads + but if the limit is exceeded with even one thread then xz + will continue with one thread using the multi-threaded + encoder and this limit is ignored. If the number of threads + is specified manually then no default limit will be used; + this affects only -T0. + + This change helps on systems that have very many cores and + using all of them for xz makes no sense. Previously xz -T0 + could run out of memory on such systems because it attempted + to reserve memory for too many threads. + + This also helps with 32-bit builds which don't have a large + amount of address space that would be required for many + threads. The default soft limit for -T0 is at most 1400 MiB + on all 32-bit platforms. + + - Previously a low value in --memlimit-compress wouldn't cause + xz to switch from multi-threaded mode to single-threaded mode + if the limit cannot otherwise be met; xz failed instead. Now + xz can switch to single-threaded mode and then, if needed, + scale down the LZMA2 dictionary size too just like it already + did when it was started in single-threaded mode. + + - The option --no-adjust no longer prevents xz from scaling down + the number of threads as that doesn't affect the compressed + output (only performance). Now --no-adjust only prevents + adjustments that affect compressed output, that is, with + --no-adjust xz won't switch from multi-threaded mode to + single-threaded mode and won't scale down the LZMA2 + dictionary size. + + - Added a new option --memlimit-mt-decompress=LIMIT. This is + used to limit the number of decompressor threads (possibly + falling back to single-threaded mode) but it will never make + xz refuse to decompress a file. This has a system-specific + default value because without any limit xz could end up + allocating memory for the whole compressed input file, the + whole uncompressed output file, multiple thread-specific + decompressor instances and so on. Basically xz could + attempt to use an insane amount of memory even with fairly + common files. The system-specific default value is currently + the same as the one used for compression with -T0. + + The new option works together with the existing option + --memlimit-decompress=LIMIT. The old option sets a hard limit + that must not be exceeded (xz will refuse to decompress) + while the new option only restricts the number of threads. + If the limit set with --memlimit-mt-decompress is greater + than the limit set with --memlimit-compress, then the latter + value is used also for --memlimit-mt-decompress. + + - Added new information to the output of xz --info-memory and + new fields to the output of xz --robot --info-memory. + + - In --lzma2=nice=NUMBER allow 2 and 3 with all match finders + now that liblzma handles it. + + - Don't mention endianness for ARM and ARM-Thumb filters in + --long-help. The filters only work for little endian + instruction encoding but modern ARM processors using + big endian data access still use little endian + instruction encoding. So the help text was misleading. + In contrast, the PowerPC filter is only for big endian + 32/64-bit PowerPC code. Little endian PowerPC would need + a separate filter. + + - Added decompression support for the .lz (lzip) file format + version 0 and the original unextended version 1. It is + autodetected by default. See also the option --format on + the xz man page. + + - Sandboxing enabled by default: + * Capsicum (FreeBSD) + * pledge(2) (OpenBSD) + + * Scripts now support the .lz format using xz. + + * A few new tests were added. + + * The liblzma-specific tests are now supported in CMake-based + builds too ("make test"). + + +5.3.5beta (2022-12-01) + + * All fixes from 5.2.9. + + * liblzma: + + - Added new LZMA_FILTER_LZMA1EXT for raw encoder and decoder to + handle raw LZMA1 streams that don't have end of payload marker + (EOPM) alias end of stream (EOS) marker. It can be used in + filter chains, for example, with the x86 BCJ filter. + + - Added lzma_str_to_filters(), lzma_str_from_filters(), and + lzma_str_list_filters() to make it easier for applications + to get custom compression options from a user and convert + it to an array of lzma_filter structures. + + - Added lzma_filters_free(). + + - lzma_filters_update() can now be used with the multi-threaded + encoder (lzma_stream_encoder_mt()) to change the filter chain + after LZMA_FULL_BARRIER or LZMA_FULL_FLUSH. + + - In lzma_options_lzma, allow nice_len = 2 and 3 with the match + finders that require at least 3 or 4. Now it is internally + rounded up if needed. + + - ARM64 filter was modified. It is still experimental. + + - Fixed LTO build with Clang if -fgnuc-version=10 or similar + was used to make Clang look like GCC >= 10. Now it uses + __has_attribute(__symver__) which should be reliable. + + * xz: + + - --threads=+1 or -T+1 is now a way to put xz into multi-threaded + mode while using only one worker thread. + + - In --lzma2=nice=NUMBER allow 2 and 3 with all match finders + now that liblzma handles it. + + * Updated translations: Chinese (simplified), Korean, and Turkish. + + +5.3.4alpha (2022-11-15) + + * All fixes from 5.2.7 and 5.2.8. + + * liblzma: + + - Minor improvements to the threaded decoder. + + - Added CRC64 implementation that uses SSSE3, SSE4.1, and CLMUL + instructions on 32/64-bit x86 and E2K. On 32-bit x86 it's + not enabled unless --disable-assembler is used but then + the non-CLMUL code might be slower. Processor support is + detected at runtime so this is built by default on x86-64 + and E2K. On these platforms, if compiler flags indicate + unconditional CLMUL support (-msse4.1 -mpclmul) then the + generic version is not built, making liblzma 8-9 KiB smaller + compared to having both versions included. + + With extremely compressible files this can make decompression + up to twice as fast but with typical files 5 % improvement + is a more realistic expectation. + + The CLMUL version is slower than the generic version with + tiny inputs (especially at 1-8 bytes per call, but up to + 16 bytes). In normal use in xz this doesn't matter at all. + + - Added an experimental ARM64 filter. This is *not* the final + version! Files created with this experimental version won't + be supported in the future versions! The filter design is + a compromise where improving one use case makes some other + cases worse. + + - Added decompression support for the .lz (lzip) file format + version 0 and the original unextended version 1. See the + API docs of lzma_lzip_decoder() for details. Also + lzma_auto_decoder() supports .lz files. + + - Building with --disable-threads --enable-small + is now thread-safe if the compiler supports + __attribute__((__constructor__)) + + * xz: + + - Added support for OpenBSD's pledge(2) as a sandboxing method. + + - Don't mention endianness for ARM and ARM-Thumb filters in + --long-help. The filters only work for little endian + instruction encoding but modern ARM processors using + big endian data access still use little endian + instruction encoding. So the help text was misleading. + In contrast, the PowerPC filter is only for big endian + 32/64-bit PowerPC code. Little endian PowerPC would need + a separate filter. + + - Added --experimental-arm64. This will be renamed once the + filter is finished. Files created with this experimental + filter will not be supported in the future! + + - Added new fields to the output of xz --robot --info-memory. + + - Added decompression support for the .lz (lzip) file format + version 0 and the original unextended version 1. It is + autodetected by default. See also the option --format on + the xz man page. + + * Scripts now support the .lz format using xz. + + * Build systems: + + - New #defines in config.h: HAVE_ENCODER_ARM64, + HAVE_DECODER_ARM64, HAVE_LZIP_DECODER, HAVE_CPUID_H, + HAVE_FUNC_ATTRIBUTE_CONSTRUCTOR, HAVE_USABLE_CLMUL + + - New configure options: --disable-clmul-crc, + --disable-microlzma, --disable-lzip-decoder, and + 'pledge' is now an option in --enable-sandbox (but + it's autodetected by default anyway). + + - INSTALL was updated to document the new configure options. + + - PACKAGERS now lists also --disable-microlzma and + --disable-lzip-decoder as configure options that must + not be used in builds for non-embedded use. + + * Tests: + + - Fix some of the tests so that they skip instead of fail if + certain features have been disabled with configure options. + It's still not perfect. + + - Other improvements to tests. + + * Updated translations: Croatian, Finnish, Hungarian, Polish, + Romanian, Spanish, Swedish, and Ukrainian. + + +5.3.3alpha (2022-08-22) + + * All fixes from 5.2.6. + + * liblzma: + + - Fixed 32-bit build. + + - Added threaded .xz decompressor lzma_stream_decoder_mt(). + It can use multiple threads with .xz files that have multiple + Blocks with size information in Block Headers. The threaded + encoder in xz has always created such files. + + Single-threaded encoder cannot store the size information in + Block Headers even if one used LZMA_FULL_FLUSH to create + multiple Blocks, so this threaded decoder cannot use multiple + threads with such files. + + If there are multiple Streams (concatenated .xz files), one + Stream will be decompressed completely before starting the + next Stream. + + - A new decoder flag LZMA_FAIL_FAST was added. It makes the + threaded decompressor report errors soon instead of first + flushing all pending data before the error location. + + * xz: + + - Using -T0 (--threads=0) will now use multi-threaded encoder + even on a single-core system. This is to ensure that output + from the same xz binary is identical on both single-core and + multi-core systems. + + - A default soft memory usage limit is now used for compression + when -T0 is used and no explicit limit has been specified. + This soft limit is used to restrict the number of threads + but if the limit is exceeded with even one thread then xz + will continue with one thread using the multi-threaded + encoder and this limit is ignored.

The default limit is 1400 MiB on all 32-bit + platforms with -T0. + + Now xz -T0 should just work. It might use too few threads + in some cases but at least it shouldn't easily run out of + memory. It's possible that this will be tweaked before 5.4.0. + + - Changes to --memlimit-compress and --no-adjust: + + In single-threaded mode, --memlimit-compress can make xz + scale down the LZMA2 dictionary size to meet the memory usage + limit. This obviously affects the compressed output. However, + if xz was in threaded mode, --memlimit-compress could make xz + reduce the number of threads but it wouldn't make xz switch + from multi-threaded mode to single-threaded mode or scale + down the LZMA2 dictionary size. This seemed illogical. + + Now --memlimit-compress can make xz switch to single-threaded + mode if one thread in multi-threaded mode uses too much + memory. If memory usage is still too high, then the LZMA2 + dictionary size can be scaled down too. + + The option --no-adjust was also changed so that it no longer + prevents xz from scaling down the number of threads as that + doesn't affect compressed output (only performance). After + this commit --no-adjust only prevents adjustments that affect + compressed output, that is, with --no-adjust xz won't switch + from multithreaded mode to single-threaded mode and won't + scale down the LZMA2 dictionary size. + + - Added a new option --memlimit-mt-decompress=LIMIT. This is + used to limit the number of decompressor threads (possibly + falling back to single-threaded mode) but it will never make + xz refuse to decompress a file. This has a system-specific + default value because without any limit xz could end up + allocating memory for the whole compressed input file, the + whole uncompressed output file, multiple thread-specific + decompressor instances and so on. Basically xz could + attempt to use an insane amount of memory even with fairly + common files. + + The new option works together with the existing option + --memlimit-decompress=LIMIT. The old option sets a hard limit + that must not be exceeded (xz will refuse to decompress) + while the new option only restricts the number of threads. + If the limit set with --memlimit-mt-decompress is greater + than the limit set with --memlimit-compress, then the latter + value is used also for --memlimit-mt-decompress. + + * Tests: + + - Added a few more tests. + + - Added tests/code_coverage.sh to create a code coverage report + of the tests. + + * Build systems: + + - Automake's parallel test harness is now used to make tests + finish faster. + + - Added the CMake files to the distribution tarball. These were + supposed to be in 5.2.5 already. + + - Added liblzma tests to the CMake build. + + - Windows: Fix building of liblzma.dll with the included + Visual Studio project files. + + +5.3.2alpha (2021-10-28) + + This release was made on short notice so that recent erofs-utils can + be built with LZMA support without needing a snapshot from xz.git. + Thus many pending things were not included, not even updated + translations (which would need to be updated for the new --list + strings anyway). + + * All fixes from 5.2.5. + + * xz: + + - When copying metadata from the source file to the destination + file, don't try to set the group (GID) if it is already set + correctly. This avoids a failure on OpenBSD (and possibly on + a few other OSes) where files may get created so that their + group doesn't belong to the user, and fchown(2) can fail even + if it needs to do nothing. + + - The --keep option now accepts symlinks, hardlinks, and + setuid, setgid, and sticky files. Previously this required + using --force. + + - Split the long strings used in --list and --info-memory modes + to make them much easier for translators. + + - If built with sandbox support and enabling the sandbox fails, + xz will now immediately exit with exit status of 1. Previously + it would only display a warning if -vv was used. + + - Cap --memlimit-compress to 2000 MiB on MIPS32 because on + MIPS32 userspace processes are limited to 2 GiB of address + space. + + * liblzma: + + - Added lzma_microlzma_encoder() and lzma_microlzma_decoder(). + The API is in lzma/container.h. + + The MicroLZMA format is a raw LZMA stream (without end marker) + whose first byte (always 0x00) has been replaced with + bitwise-negation of the LZMA properties (lc/lp/pb). It was + created for use in EROFS but may be used in other contexts + as well where it is important to avoid wasting bytes for + stream headers or footers. The format is also supported by + XZ Embedded. + + The MicroLZMA encoder API in liblzma can compress into a + fixed-sized output buffer so that as much data is compressed + as can be fit into the buffer while still creating a valid + MicroLZMA stream. This is needed for EROFS. + + - Added fuzzing support. + + - Support Intel Control-flow Enforcement Technology (CET) in + 32-bit x86 assembly files. + + - Visual Studio: Use non-standard _MSVC_LANG to detect C++ + standard version in the lzma.h API header. It's used to + detect when "noexcept" can be used. + + * Scripts: + + - Fix exit status of xzdiff/xzcmp. Exit status could be 2 when + the correct value is 1. + + - Fix exit status of xzgrep. + + - Detect corrupt .bz2 files in xzgrep. + + - Add zstd support to xzgrep and xzdiff/xzcmp. + + - Fix less(1) version detection in xzless. It failed if the + version number from "less -V" contained a dot. + + * Fix typos and technical issues in man pages. + + * Build systems: + + - Windows: Fix building of resource files when config.h isn't + used. CMake + Visual Studio can now build liblzma.dll. + + - Various fixes to the CMake support. It might still need a few + more fixes even for liblzma-only builds. + + +5.3.1alpha (2018-04-29) + + * All fixes from 5.2.4. + + * Add lzma_file_info_decoder() into liblzma and use it in xz to + implement the --list feature. + + * Capsicum sandbox support is enabled by default where available + (FreeBSD >= 10). + + +5.2.10 (2022-12-13) + + * xz: Don't modify argv[] when parsing the --memlimit* and + --block-list command line options. This fixes confusing + arguments in process listing (like "ps auxf"). + + * GNU/Linux only: Use __has_attribute(__symver__) to detect if + that attribute is supported. This fixes build on Mandriva where + Clang is patched to define __GNUC__ to 11 by default (instead + of 4 as used by Clang upstream). + + +5.2.9 (2022-11-30) + + * liblzma: + + - Fixed an infinite loop in LZMA encoder initialization + if dict_size >= 2 GiB. (The encoder only supports up + to 1536 MiB.) + + - Fixed two cases of invalid free() that can happen if + a tiny allocation fails in encoder re-initialization + or in lzma_filters_update(). These bugs had some + similarities with the bug fixed in 5.2.7. + + - Fixed lzma_block_encoder() not allowing the use of + LZMA_SYNC_FLUSH with lzma_code() even though it was + documented to be supported. The sync-flush code in + the Block encoder was already used internally via + lzma_stream_encoder(), so this was just a missing flag + in the lzma_block_encoder() API function. + + - GNU/Linux only: Don't put symbol versions into static + liblzma as it breaks things in some cases (and even if + it didn't break anything, symbol versions in static + libraries are useless anyway). The downside of the fix + is that if the configure options --with-pic or --without-pic + are used then it's not possible to build both shared and + static liblzma at the same time on GNU/Linux anymore; + with those options --disable-static or --disable-shared + must be used too. + + * New email address for bug reports is which + forwards messages to Lasse Collin and Jia Tan. + + +5.2.8 (2022-11-13) + + * xz: + + - If xz cannot remove an input file when it should, this + is now treated as a warning (exit status 2) instead of + an error (exit status 1). This matches GNU gzip and it + is more logical as at that point the output file has + already been successfully closed. + + - Fix handling of .xz files with an unsupported check type. + Previously such printed a warning message but then xz + behaved as if an error had occurred (didn't decompress, + exit status 1). Now a warning is printed, decompression + is done anyway, and exit status is 2. This used to work + slightly before 5.0.0. In practice this bug matters only + if xz has been built with some check types disabled. As + instructed in PACKAGERS, such builds should be done in + special situations only. + + - Fix "xz -dc --single-stream tests/files/good-0-empty.xz" + which failed with "Internal error (bug)". That is, + --single-stream was broken if the first .xz stream in + the input file didn't contain any uncompressed data. + + - Fix displaying file sizes in the progress indicator when + working in passthru mode and there are multiple input files. + Just like "gzip -cdf", "xz -cdf" works like "cat" when the + input file isn't a supported compressed file format. In + this case the file size counters weren't reset between + files so with multiple input files the progress indicator + displayed an incorrect (too large) value. + + * liblzma: + + - API docs in lzma/container.h: + * Update the list of decoder flags in the decoder + function docs. + * Explain LZMA_CONCATENATED behavior with .lzma files + in lzma_auto_decoder() docs. + + - OpenBSD: Use HW_NCPUONLINE to detect the number of + available hardware threads in lzma_physmem(). + + - Fix use of wrong macro to detect x86 SSE2 support. + __SSE2_MATH__ was used with GCC/Clang but the correct + one is __SSE2__. The first one means that SSE2 is used + for floating point math which is irrelevant here. + The affected SSE2 code isn't used on x86-64 so this affects + only 32-bit x86 builds that use -msse2 without -mfpmath=sse + (there is no runtime detection for SSE2). It improves LZMA + compression speed (not decompression). + + - Fix the build with Intel C compiler 2021 (ICC, not ICX) + on Linux. It defines __GNUC__ to 10 but doesn't support + the __symver__ attribute introduced in GCC 10. + + * Scripts: Ignore warnings from xz by using --quiet --no-warn. + This is needed if the input .xz files use an unsupported + check type. + + * Translations: + + - Updated Croatian and Turkish translations. + + - One new translations wasn't included because it needed + technical fixes. It will be in upcoming 5.4.0. No new + translations will be added to the 5.2.x branch anymore. + + - Renamed the French man page translation file from + fr_FR.po to fr.po and thus also its install directory + (like /usr/share/man/fr_FR -> .../fr). + + - Man page translations for upcoming 5.4.0 are now handled + in the Translation Project. + + * Update doc/faq.txt a little so it's less out-of-date. + + +5.2.7 (2022-09-30) + + * liblzma: + + - Made lzma_filters_copy() to never modify the destination + array if an error occurs. lzma_stream_encoder() and + lzma_stream_encoder_mt() already assumed this. Before this + change, if a tiny memory allocation in lzma_filters_copy() + failed it would lead to a crash (invalid free() or invalid + memory reads) in the cleanup paths of these two encoder + initialization functions. + + - Added missing integer overflow check to lzma_index_append(). + This affects xz --list and other applications that decode + the Index field from .xz files using lzma_index_decoder(). + Normal decompression of .xz files doesn't call this code + and thus most applications using liblzma aren't affected + by this bug. + + - Single-threaded .xz decoder (lzma_stream_decoder()): If + lzma_code() returns LZMA_MEMLIMIT_ERROR it is now possible + to use lzma_memlimit_set() to increase the limit and continue + decoding. This was supposed to work from the beginning + but there was a bug. With other decoders (.lzma or + threaded .xz decoder) this already worked correctly. + + - Fixed accumulation of integrity check type statistics in + lzma_index_cat(). This bug made lzma_index_checks() return + only the type of the integrity check of the last Stream + when multiple lzma_indexes were concatenated. Most + applications don't use these APIs but in xz it made + xz --list not list all check types from concatenated .xz + files. In xz --list --verbose only the per-file "Check:" + lines were affected and in xz --robot --list only the "file" + line was affected. + + - Added ABI compatibility with executables that were linked + against liblzma in RHEL/CentOS 7 or other liblzma builds + that had copied the problematic patch from RHEL/CentOS 7 + (xz-5.2.2-compat-libs.patch). For the details, see the + comment at the top of src/liblzma/validate_map.sh. + + WARNING: This uses __symver__ attribute with GCC >= 10. + In other cases the traditional __asm__(".symver ...") + is used. Using link-time optimization (LTO, -flto) with + GCC versions older than 10 can silently result in + broken liblzma.so.5 (incorrect symbol versions)! If you + want to use -flto with GCC, you must use GCC >= 10. + LTO with Clang seems to work even with the traditional + __asm__(".symver ...") method. + + * xzgrep: Fixed compatibility with old shells that break if + comments inside command substitutions have apostrophes ('). + This problem was introduced in 5.2.6. + + * Build systems: + + - New #define in config.h: HAVE_SYMBOL_VERSIONS_LINUX + + - Windows: Fixed liblzma.dll build with Visual Studio project + files. It broke in 5.2.6 due to a change that was made to + improve CMake support. + + - Windows: Building liblzma with UNICODE defined should now + work. + + - CMake files are now actually included in the release tarball. + They should have been in 5.2.5 already. + + - Minor CMake fixes and improvements. + + * Added a new translation: Turkish + + +5.2.6 (2022-08-12) + + * xz: + + - The --keep option now accepts symlinks, hardlinks, and + setuid, setgid, and sticky files. Previously this required + using --force. + + - When copying metadata from the source file to the destination + file, don't try to set the group (GID) if it is already set + correctly. This avoids a failure on OpenBSD (and possibly on + a few other OSes) where files may get created so that their + group doesn't belong to the user, and fchown(2) can fail even + if it needs to do nothing. + + - Cap --memlimit-compress to 2000 MiB instead of 4020 MiB on + MIPS32 because on MIPS32 userspace processes are limited + to 2 GiB of address space. + + * liblzma: + + - Fixed a missing error-check in the threaded encoder. If a + small memory allocation fails, a .xz file with an invalid + Index field would be created. Decompressing such a file would + produce the correct output but result in an error at the end. + Thus this is a "mild" data corruption bug. Note that while + a failed memory allocation can trigger the bug, it cannot + cause invalid memory access. + + - The decoder for .lzma files now supports files that have + uncompressed size stored in the header and still use the + end of payload marker (end of stream marker) at the end + of the LZMA stream. Such files are rare but, according to + the documentation in LZMA SDK, they are valid. + doc/lzma-file-format.txt was updated too. + + - Improved 32-bit x86 assembly files: + * Support Intel Control-flow Enforcement Technology (CET) + * Use non-executable stack on FreeBSD. + + - Visual Studio: Use non-standard _MSVC_LANG to detect C++ + standard version in the lzma.h API header. It's used to + detect when "noexcept" can be used. + + * xzgrep: + + - Fixed arbitrary command injection via a malicious filename + (CVE-2022-1271, ZDI-CAN-16587). A standalone patch for + this was released to the public on 2022-04-07. A slight + robustness improvement has been made since then and, if + using GNU or *BSD grep, a new faster method is now used + that doesn't use the old sed-based construct at all. This + also fixes bad output with GNU grep >= 3.5 (2020-09-27) + when xzgrepping binary files. + + This vulnerability was discovered by: + cleemy desu wayo working with Trend Micro Zero Day Initiative + + - Fixed detection of corrupt .bz2 files. + + - Improved error handling to fix exit status in some situations + and to fix handling of signals: in some situations a signal + didn't make xzgrep exit when it clearly should have. It's + possible that the signal handling still isn't quite perfect + but hopefully it's good enough. + + - Documented exit statuses on the man page. + + - xzegrep and xzfgrep now use "grep -E" and "grep -F" instead + of the deprecated egrep and fgrep commands. + + - Fixed parsing of the options -E, -F, -G, -P, and -X. The + problem occurred when multiple options were specified in + a single argument, for example, + + echo foo | xzgrep -Fe foo + + treated foo as a filename because -Fe wasn't correctly + split into -F -e. + + - Added zstd support. + + * xzdiff/xzcmp: + + - Fixed wrong exit status. Exit status could be 2 when the + correct value is 1. + + - Documented on the man page that exit status of 2 is used + for decompression errors. + + - Added zstd support. + + * xzless: + + - Fix less(1) version detection. It failed if the version number + from "less -V" contained a dot. + + * Translations: + + - Added new translations: Catalan, Croatian, Esperanto, + Korean, Portuguese, Romanian, Serbian, Spanish, Swedish, + and Ukrainian + + - Updated the Brazilian Portuguese translation. + + - Added French man page translation. This and the existing + German translation aren't complete anymore because the + English man pages got a few updates and the translators + weren't reached so that they could update their work. + + * Build systems: + + - Windows: Fix building of resource files when config.h isn't + used. CMake + Visual Studio can now build liblzma.dll. + + - Various fixes to the CMake support. Building static or shared + liblzma should work fine in most cases. In contrast, building + the command line tools with CMake is still clearly incomplete + and experimental and should be used for testing only. + + +5.2.5 (2020-03-17) + + * liblzma: + + - Fixed several C99/C11 conformance bugs. Now the code is clean + under gcc/clang -fsanitize=undefined. Some of these changes + might have a negative effect on performance with old GCC + versions or compilers other than GCC and Clang. The configure + option --enable-unsafe-type-punning can be used to (mostly) + restore the old behavior but it shouldn't normally be used. + + - Improved API documentation of lzma_properties_decode(). + + - Added a very minor encoder speed optimization. + + * xz: + + - Fixed a crash in "xz -dcfv not_an_xz_file". All four options + were required to trigger it. The crash occurred in the + progress indicator code when xz was in passthru mode where + xz works like "cat". + + - Fixed an integer overflow with 32-bit off_t. It could happen + when decompressing a file that has a long run of zero bytes + which xz would try to write as a sparse file. Since the build + system enables large file support by default, off_t is + normally 64-bit even on 32-bit systems. + + - Fixes for --flush-timeout: + * Fix semi-busy-waiting. + * Avoid unneeded flushes when no new input has arrived + since the previous flush was completed. + + - Added a special case for 32-bit xz: If --memlimit-compress is + used to specify a limit that exceeds 4020 MiB, the limit will + be set to 4020 MiB. The values "0" and "max" aren't affected + by this and neither is decompression. This hack can be + helpful when a 32-bit xz has access to 4 GiB address space + but the specified memlimit exceeds 4 GiB. This can happen + e.g. with some scripts. + + - Capsicum sandbox is now enabled by default where available + (FreeBSD >= 10). The sandbox debug messages (xz -vv) were + removed since they seemed to be more annoying than useful. + + - DOS build now requires DJGPP 2.05 instead of 2.04beta. + A workaround for a locale problem with DJGPP 2.05 was added. + + * xzgrep and other scripts: + + - Added a configure option --enable-path-for-scripts=PREFIX. + It is disabled by default except on Solaris where the default + is /usr/xpg4/bin. See INSTALL for details. + + - Added a workaround for a POSIX shell detection problem on + Solaris. + + * Build systems: + + - Added preliminary build instructions for z/OS. See INSTALL + section 1.2.9. + + - Experimental CMake support was added. It should work to build + static liblzma on a few operating systems. It may or may not + work to build shared liblzma. On some platforms it can build + xz and xzdec too but those are only for testing. See the + comment in the beginning of CMakeLists.txt for details. + + - Visual Studio project files were updated. + WindowsTargetPlatformVersion was removed from VS2017 files + and set to "10.0" in the added VS2019 files. In the future + the VS project files will be removed when CMake support is + good enough. + + - New #defines in config.h: HAVE___BUILTIN_ASSUME_ALIGNED, + HAVE___BUILTIN_BSWAPXX, and TUKLIB_USE_UNSAFE_TYPE_PUNNING. + + - autogen.sh has a new optional dependency on po4a and a new + option --no-po4a to skip that step. This matters only if one + wants to remake the build files. po4a is used to update the + translated man pages but as long as the man pages haven't + been modified, there's nothing to update and one can use + --no-po4a to avoid the dependency on po4a. + + * Translations: + + - XZ Utils translations are now handled by the Translation + Project: https://translationproject.org/domain/xz.html + + - All man pages are now included in German too. + + - New xz translations: Brazilian Portuguese, Finnish, + Hungarian, Chinese (simplified), Chinese (traditional), + and Danish (partial translation) + + - Updated xz translations: French, German, Italian, and Polish + + - Unfortunately a few new xz translations weren't included due + to technical problems like too long lines in --help output or + misaligned column headings in tables. In the future, many of + these strings will be split and e.g. the table column + alignment will be handled in software. This should make the + strings easier to translate. + + +5.2.4 (2018-04-29) + + * liblzma: + + - Allow 0 as memory usage limit instead of returning + LZMA_PROG_ERROR. Now 0 is treated as if 1 byte was specified, + which effectively is the same as 0. + + - Use "noexcept" keyword instead of "throw()" in the public + headers when a C++11 (or newer standard) compiler is used. + + - Added a portability fix for recent Intel C Compilers. + + - Microsoft Visual Studio build files have been moved under + windows/vs2013 and windows/vs2017. + + * xz: + + - Fix "xz --list --robot missing_or_bad_file.xz" which would + try to print an uninitialized string and thus produce garbage + output. Since the exit status is non-zero, most uses of such + a command won't try to interpret the garbage output. + + - "xz --list foo.xz" could print "Internal error (bug)" in a + corner case where a specific memory usage limit had been set. + + +5.2.3 (2016-12-30) + + * xz: + + - Always close a file before trying to delete it to avoid + problems on some operating system and file system combinations. + + - Fixed copying of file timestamps on Windows. + + - Added experimental (disabled by default) sandbox support using + Capsicum (FreeBSD >= 10). See --enable-sandbox in INSTALL. + + * C99/C11 conformance fixes to liblzma. The issues affected at least + some builds using link-time optimizations. + + * Fixed bugs in the rarely-used function lzma_index_dup(). + + * Use of external SHA-256 code is now disabled by default. + It can still be enabled by passing --enable-external-sha256 + to configure. The reasons to disable it by default (see INSTALL + for more details): + + - Some OS-specific SHA-256 implementations conflict with + OpenSSL and cause problems in programs that link against both + liblzma and libcrypto. At least FreeBSD 10 and MINIX 3.3.0 + are affected. + + - The internal SHA-256 is faster than the SHA-256 code in + some operating systems. + + * Changed CPU core count detection to use sched_getaffinity() on + GNU/Linux and GNU/kFreeBSD. + + * Fixes to the build-system and xz to make xz buildable even when + encoders, decoders, or threading have been disabled from libilzma + using configure options. These fixes added two new #defines to + config.h: HAVE_ENCODERS and HAVE_DECODERS. + + +5.2.2 (2015-09-29) + + * Fixed bugs in QNX-specific code. + + * Omitted the use of pipe2() even if it is available to avoid + portability issues with some old Linux and glibc combinations. + + * Updated German translation. + + * Added project files to build static and shared liblzma (not the + whole XZ Utils) with Visual Studio 2013 update 2 or later. + + * Documented that threaded decompression hasn't been implemented + yet. A 5.2.0 NEWS entry describing multi-threading support had + incorrectly said "decompression" when it should have said + "compression". + + +5.2.1 (2015-02-26) + + * Fixed a compression-ratio regression in fast mode of LZMA1 and + LZMA2. The bug is present in 5.1.4beta and 5.2.0 releases. + + * Fixed a portability problem in xz that affected at least OpenBSD. + + * Fixed xzdiff to be compatible with FreeBSD's mktemp which differs + from most other mktemp implementations. + + * Changed CPU core count detection to use cpuset_getaffinity() on + FreeBSD. + + +5.2.0 (2014-12-21) + + Since 5.1.4beta: + + * All fixes from 5.0.8 + + * liblzma: Fixed lzma_stream_encoder_mt_memusage() when a preset + was used. + + * xzdiff: If mktemp isn't installed, mkdir will be used as + a fallback to create a temporary directory. Installing mktemp + is still recommended. + + * Updated French, German, Italian, Polish, and Vietnamese + translations. + + Summary of fixes and new features added in the 5.1.x development + releases: + + * liblzma: + + - Added support for multi-threaded compression. See the + lzma_mt structure, lzma_stream_encoder_mt(), and + lzma_stream_encoder_mt_memusage() in , + lzma_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 is enabled by default + on GNU/Linux, other GNU-based systems, and FreeBSD. + + - liblzma (not the whole XZ Utils) should now be buildable + with MSVC 2013 update 2 or later using windows/config.h. + + * xz: + + - Fixed a race condition in the signal handling. It was + possible that e.g. the first SIGINT didn't make xz exit + if reading or writing blocked and one had bad luck. The fix + is non-trivial, so as of writing it is unknown if it will be + backported to the v5.0 branch. + + - Multi-threaded compression can be enabled with the + --threads (-T) option. + [Fixed: This originally said "decompression".] + + - New command line options in xz: --single-stream, + --block-size=SIZE, --block-list=SIZES, + --flush-timeout=TIMEOUT, and --ignore-check. + + - xz -lvv now shows the minimum xz version that is required to + decompress the file. Currently it is 5.0.0 for all supported + .xz files except files with empty LZMA2 streams require 5.0.2. + + * xzdiff and xzgrep now support .lzo files if lzop is installed. + The .tzo suffix is also recognized as a shorthand for .tar.lzo. + + +5.1.4beta (2014-09-14) + + * All fixes from 5.0.6 + + * liblzma: Fixed the use of presets in threaded encoder + initialization. + + * xz --block-list and --block-size can now be used together + in single-threaded mode. Previously the combination only + worked in multi-threaded mode. + + * Added support for LZMA_IGNORE_CHECK to liblzma and made it + available in xz as --ignore-check. + + * liblzma speed optimizations: + + - Initialization of a new LZMA1 or LZMA2 encoder has been + optimized. (The speed of reinitializing an already-allocated + encoder isn't affected.) This helps when compressing many + small buffers with lzma_stream_buffer_encode() and other + similar situations where an already-allocated encoder state + isn't reused. This speed-up is visible in xz too if one + compresses many small files one at a time instead running xz + once and giving all files as command-line arguments. + + - Buffer comparisons are now much faster when unaligned access + is allowed (configured with --enable-unaligned-access). This + speeds up encoding significantly. There is arch-specific code + for 32-bit and 64-bit x86 (32-bit needs SSE2 for the best + results and there's no run-time CPU detection for now). + For other archs there is only generic code which probably + isn't as optimal as arch-specific solutions could be. + + - A few speed optimizations were made to the SHA-256 code. + (Note that the builtin SHA-256 code isn't used on all + operating systems.) + + * liblzma can now be built with MSVC 2013 update 2 or later + using windows/config.h. + + * Vietnamese translation was added. + + +5.1.3alpha (2013-10-26) + + * All fixes from 5.0.5 + + * liblzma: + + - Fixed a deadlock in the threaded encoder. + + - Made the uses of lzma_allocator const correct. + + - Added lzma_block_uncomp_encode() to create uncompressed + .xz Blocks using LZMA2 uncompressed chunks. + + - Added support for native threads on Windows and the ability + to detect the number of CPU cores. + + * xz: + + - Fixed a race condition in the signal handling. It was + possible that e.g. the first SIGINT didn't make xz exit + if reading or writing blocked and one had bad luck. The fix + is non-trivial, so as of writing it is unknown if it will be + backported to the v5.0 branch. + + - Made the progress indicator work correctly in threaded mode. + + - Threaded encoder now works together with --block-list=SIZES. + + - Added preliminary support for --flush-timeout=TIMEOUT. + It can be useful for (somewhat) real-time streaming. For + now the decompression side has to be done with something + else than the xz tool due to how xz does buffering, but this + should be fixed. + + +5.1.2alpha (2012-07-04) + + * All fixes from 5.0.3 and 5.0.4 + + * liblzma: + + - Fixed a deadlock and an invalid free() in the threaded encoder. + + - Added support for symbol versioning. It is enabled by default + on GNU/Linux, other GNU-based systems, and FreeBSD. + + - Use SHA-256 implementation from the operating system if one is + available in libc, libmd, or libutil. liblzma won't use e.g. + OpenSSL or libgcrypt to avoid introducing new dependencies. + + - Fixed liblzma.pc for static linking. + + - Fixed a few portability bugs. + + * xz --decompress --single-stream now fixes the input position after + successful decompression. Now the following works: + + echo foo | xz > foo.xz + echo bar | xz >> foo.xz + ( xz -dc --single-stream ; xz -dc --single-stream ) < foo.xz + + Note that it doesn't work if the input is not seekable + or if there is Stream Padding between the concatenated + .xz Streams. + + * xz -lvv now shows the minimum xz version that is required to + decompress the file. Currently it is 5.0.0 for all supported .xz + files except files with empty LZMA2 streams require 5.0.2. + + * Added an *incomplete* implementation of --block-list=SIZES to xz. + It only works correctly in single-threaded mode and when + --block-size isn't used at the same time. --block-list allows + specifying the sizes of Blocks which can be useful e.g. when + creating files for random-access reading. + + +5.1.1alpha (2011-04-12) + + * All fixes from 5.0.2 + + * liblzma fixes that will also be included in 5.0.3: + + - A memory leak was fixed. + + - lzma_stream_buffer_encode() no longer creates an empty .xz + Block if encoding an empty buffer. Such an empty Block with + LZMA2 data would trigger a bug in 5.0.1 and older (see the + first bullet point in 5.0.2 notes). When releasing 5.0.2, + I thought that no encoder creates this kind of files but + I was wrong. + + - Validate function arguments better in a few functions. Most + importantly, specifying an unsupported integrity check to + lzma_stream_buffer_encode() no longer creates a corrupt .xz + file. Probably no application tries to do that, so this + shouldn't be a big problem in practice. + + - Document that lzma_block_buffer_encode(), + lzma_easy_buffer_encode(), lzma_stream_encoder(), and + lzma_stream_buffer_encode() may return LZMA_UNSUPPORTED_CHECK. + + - The return values of the _memusage() functions are now + documented better. + + * Support for multithreaded compression was added using the simplest + method, which splits the input data into blocks and compresses + them independently. Other methods will be added in the future. + The current method has room for improvement, e.g. it is possible + to reduce the memory usage. + + * Added the options --single-stream and --block-size=SIZE to xz. + + * xzdiff and xzgrep now support .lzo files if lzop is installed. + The .tzo suffix is also recognized as a shorthand for .tar.lzo. + + * Support for short 8.3 filenames under DOS was added to xz. It is + experimental and may change before it gets into a stable release. + + +5.0.8 (2014-12-21) + + * Fixed an old bug in xzgrep that affected OpenBSD and probably + a few other operating systems too. + + * Updated French and German translations. + + * Added support for detecting the amount of RAM on AmigaOS/AROS. + + * Minor build system updates. + + +5.0.7 (2014-09-20) + + * Fix regressions introduced in 5.0.6: + + - Fix building with non-GNU make. + + - Fix invalid Libs.private value in liblzma.pc which broke + static linking against liblzma if the linker flags were + taken from pkg-config. + + +5.0.6 (2014-09-14) + + * xzgrep now exits with status 0 if at least one file matched. + + * A few minor portability and build system fixes + + +5.0.5 (2013-06-30) + + * lzmadec and liblzma's lzma_alone_decoder(): Support decompressing + .lzma files that have less common settings in the headers + (dictionary size other than 2^n or 2^n + 2^(n-1), or uncompressed + size greater than 256 GiB). The limitations existed to avoid false + positives when detecting .lzma files. The lc + lp <= 4 limitation + still remains since liblzma's LZMA decoder has that limitation. + + NOTE: xz's .lzma support or liblzma's lzma_auto_decoder() are NOT + affected by this change. They still consider uncommon .lzma headers + as not being in the .lzma format. Changing this would give way too + many false positives. + + * xz: + + - Interaction of preset and custom filter chain options was + made less illogical. This affects only certain less typical + uses cases so few people are expected to notice this change. + + Now when a custom filter chain option (e.g. --lzma2) is + specified, all preset options (-0 ... -9, -e) earlier are on + the command line are completely forgotten. Similarly, when + a preset option is specified, all custom filter chain options + earlier on the command line are completely forgotten. + + Example 1: "xz -9 --lzma2=preset=5 -e" is equivalent to "xz -e" + which is equivalent to "xz -6e". Earlier -e didn't put xz back + into preset mode and thus the example command was equivalent + to "xz --lzma2=preset=5". + + Example 2: "xz -9e --lzma2=preset=5 -7" is equivalent to + "xz -7". Earlier a custom filter chain option didn't make + xz forget the -e option so the example was equivalent to + "xz -7e". + + - Fixes and improvements to error handling. + + - Various fixes to the man page. + + * xzless: Fixed to work with "less" versions 448 and later. + + * xzgrep: Made -h an alias for --no-filename. + + * Include the previously missing debug/translation.bash which can + be useful for translators. + + * Include a build script for Mac OS X. This has been in the Git + repository since 2010 but due to a mistake in Makefile.am the + script hasn't been included in a release tarball before. + + +5.0.4 (2012-06-22) + + * liblzma: + + - Fix lzma_index_init(). It could crash if memory allocation + failed. + + - Fix the possibility of an incorrect LZMA_BUF_ERROR when a BCJ + filter is used and the application only provides exactly as + much output space as is the uncompressed size of the file. + + - Fix a bug in doc/examples_old/xz_pipe_decompress.c. It didn't + check if the last call to lzma_code() really returned + LZMA_STREAM_END, which made the program think that truncated + files are valid. + + - New example programs in doc/examples (old programs are now in + doc/examples_old). These have more comments and more detailed + error handling. + + * Fix "xz -lvv foo.xz". It could crash on some corrupted files. + + * Fix output of "xz --robot -lv" and "xz --robot -lvv" which + incorrectly printed the filename also in the "foo (x/x)" format. + + * Fix exit status of "xzdiff foo.xz bar.xz". + + * Fix exit status of "xzgrep foo binary_file". + + * Fix portability to EBCDIC systems. + + * Fix a configure issue on AIX with the XL C compiler. See INSTALL + for details. + + * Update French, German, Italian, and Polish translations. + + +5.0.3 (2011-05-21) + + * liblzma fixes: + + - A memory leak was fixed. + + - lzma_stream_buffer_encode() no longer creates an empty .xz + Block if encoding an empty buffer. Such an empty Block with + LZMA2 data would trigger a bug in 5.0.1 and older (see the + first bullet point in 5.0.2 notes). When releasing 5.0.2, + I thought that no encoder creates this kind of files but + I was wrong. + + - Validate function arguments better in a few functions. Most + importantly, specifying an unsupported integrity check to + lzma_stream_buffer_encode() no longer creates a corrupt .xz + file. Probably no application tries to do that, so this + shouldn't be a big problem in practice. + + - Document that lzma_block_buffer_encode(), + lzma_easy_buffer_encode(), lzma_stream_encoder(), and + lzma_stream_buffer_encode() may return LZMA_UNSUPPORTED_CHECK. + + - The return values of the _memusage() functions are now + documented better. + + * Fix command name detection in xzgrep. xzegrep and xzfgrep now + correctly use egrep and fgrep instead of grep. + + * French translation was added. + + +5.0.2 (2011-04-01) + + * LZMA2 decompressor now correctly accepts LZMA2 streams with no + uncompressed data. Previously it considered them corrupt. The + bug can affect applications that use raw LZMA2 streams. It is + very unlikely to affect .xz files because no compressor creates + .xz files with empty LZMA2 streams. (Empty .xz files are a + different thing than empty LZMA2 streams.) + + * "xz --suffix=.foo filename.foo" now refuses to compress the + file due to it already having the suffix .foo. It was already + documented on the man page, but the code lacked the test. + + * "xzgrep -l foo bar.xz" works now. + + * Polish translation was added. + + +5.0.1 (2011-01-29) + + * xz --force now (de)compresses files that have setuid, setgid, + or sticky bit set and files that have multiple hard links. + The man page had it documented this way already, but the code + had a bug. + + * gzip and bzip2 support in xzdiff was fixed. + + * Portability fixes + + * Minor fix to Czech translation + + +5.0.0 (2010-10-23) + + Only the most important changes compared to 4.999.9beta are listed + here. One change is especially important: + + * The memory usage limit is now disabled by default. Some scripts + written before this change may have used --memory=max on xz command + line or in XZ_OPT. THESE USES OF --memory=max SHOULD BE REMOVED + NOW, because they interfere with user's ability to set the memory + usage limit himself. If user-specified limit causes problems to + your script, blame the user. + + Other significant changes: + + * Added support for XZ_DEFAULTS environment variable. This variable + allows users to set default options for xz, e.g. default memory + usage limit or default compression level. Scripts that use xz + must never set or unset XZ_DEFAULTS. Scripts should use XZ_OPT + instead if they need a way to pass options to xz via an + environment variable. + + * The compression settings associated with the preset levels + -0 ... -9 have been changed. --extreme was changed a little too. + It is now less likely to make compression worse, but with some + files the new --extreme may compress slightly worse than the old + --extreme. + + * If a preset level (-0 ... -9) is specified after a custom filter + chain options have been used (e.g. --lzma2), the custom filter + chain will be forgotten. Earlier the preset options were + completely ignored after custom filter chain options had been + seen. + + * xz will create sparse files when decompressing if the uncompressed + data contains long sequences of binary zeros. This is done even + when writing to standard output that is connected to a regular + file and certain additional conditions are met to make it safe. + + * Support for "xz --list" was added. Combine with --verbose or + --verbose --verbose (-vv) for detailed output. + + * I had hoped that liblzma API would have been stable after + 4.999.9beta, but there have been a couple of changes in the + advanced features, which don't affect most applications: + + - Index handling code was revised. If you were using the old + API, you will get a compiler error (so it's easy to notice). + + - A subtle but important change was made to the Block handling + API. lzma_block.version has to be initialized even for + lzma_block_header_decode(). Code that doesn't do it will work + for now, but might break in the future, which makes this API + change easy to miss. + + * The major soname has been bumped to 5.0.0. liblzma API and ABI + are now stable, so the need to recompile programs linking against + liblzma shouldn't arise soon. + diff --git a/PACKAGERS b/PACKAGERS new file mode 100644 index 0000000..3042c66 --- /dev/null +++ b/PACKAGERS @@ -0,0 +1,243 @@ + +Information to packagers of XZ Utils +==================================== + + 0.

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.

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 (*) + --disable-microlzma (*) + --disable-lzip-decoder (*) + + (*) 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. + + The Doxygen-generated documentation (HTML) for the liblzma API + headers is included in the source release and will be installed by + "make install" to $docdir/api. All JavaScript is removed to + simplify license compliance and to reduce the install size. If the + liblzma API documentation is not desired, either run configure with + --disable-doc or remove the doc/api directory before running + "make install". + + +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 0000000..9e76301 --- /dev/null +++ b/README @@ -0,0 +1,307 @@ + +XZ Utils +======== + + 0.

Other implementations of the .xz format + 6. Contact information + + +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 supports multithreaded compression. XZ Utils doesn't support + multithreaded decompression yet. It has been planned though and taken + into account when designing the .xz file format. In the future, files + that were created in threaded mode can be decompressed in threaded + mode too. + + +1. Documentation +---------------- + +1.1.

Documentation for command-line tools + + The command-line tools are documented as man pages. In source code + releases (and possibly also in some binary packages), the man pages + are also provided in plain text (ASCII only) and PDF formats in the + directory "doc/man" to make the man pages more accessible to those + whose operating system doesn't provide an easy way to view man pages. + + +1.3. Documentation for liblzma + + The liblzma API headers include short docs about each function + and data type as Doxygen tags. These docs should be quite OK as + a quick reference. + + There are a few example/tutorial programs that should help in + getting started with liblzma. In the source package the examples + are in "doc/examples" and in binary packages they may be under + "examples" in the same directory as this README. + + Since the liblzma API has similarities to the zlib API, some people + may find it useful to read the zlib docs and tutorial too: + + https://zlib.net/manual.html + https://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. Translations +--------------- + + The xz command line tool and all man pages can be translated. + The translations are handled via the Translation Project. If you + wish to help translating xz, please join the Translation Project: + + https://translationproject.org/html/translators.html + + Below are notes and testing instructions specific to xz + translations. + + Testing can be done 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. Some comments suggest + testing with a specific command which needs an .xz file. You + may use e.g. any tests/files/good-*.xz. However, these test + commands are included in translations.bash output, so reading + translations.bash output carefully can be enough. + + - 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. + + Thanks for your help! + + +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. + + https://7-zip.org/ + https://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. + + https://tukaani.org/xz/embedded.html + + XZ for Java is a complete implementation written in pure Java. + + https://tukaani.org/xz/java.html + + +6.

With some files + --extreme isn't enough though: it's most likely with files that + compress extremely well, so going from compression ratio of 0.003 + to 0.004 means big relative increase in the compressed file size. + + xz doesn't quote unprintable characters when it displays file names + given on the command line. + + tuklib_exit() doesn't block signals => EINTR is possible. + + SIGTSTP is not handled. If xz is stopped, the estimated remaining + time and calculated (de)compression speed won't make sense in the + progress indicator (xz --verbose). + + If liblzma has created threads and fork() gets called, liblzma + code will break in the child process unless it calls exec() and + doesn't touch liblzma. + + +Missing features +---------------- + + Add support for storing metadata in .xz files. A preliminary + idea is to create a new Stream type for metadata. When both + metadata and data are wanted in the same .xz file, two or more + Streams would be concatenated. + + The state stored in lzma_stream should be cloneable, which would + be mostly useful when using a preset dictionary in LZMA2, but + it may have other uses too. Compare to deflateCopy() in zlib. + + Support LZMA_FINISH in raw decoder to indicate end of LZMA1 and + other streams that don't have an end of payload marker. + + Adjust dictionary size when the input file size is known. + Maybe do this only if an option is given. + + xz doesn't support copying extended attributes, access control + lists etc. from source to target file. + + Multithreaded compression: + - Reduce memory usage of the current method. + - Implement threaded match finders. + - Implement pigz-style threading in LZMA2. + + Buffer-to-buffer coding could use less RAM (especially when + decompressing LZMA1 or LZMA2). + + I/O library is not implemented (similar to gzopen() in zlib). + It will be a separate library that supports uncompressed, .gz, + .bz2, .lzma, and .xz files. + + Support changing lzma_options_lzma.mode with lzma_filters_update(). + + Support LZMA_FULL_FLUSH for lzma_stream_decoder() to stop at + Block and Stream boundaries. + + lzma_strerror() to convert lzma_ret to human readable form? + This is tricky, because the same error codes are used with + slightly different meanings, and this cannot be fixed anymore. + + Make it possible to adjust LZMA2 options in the middle of a Block + so that the encoding speed vs. compression ratio can be optimized + when the compressed data is streamed over network. + + Improved BCJ filters.

Detailed Description

Data types and functions used in many places in liblzma API.

Macro Definition Documentation

+ +

◆ LZMA_STREAM_INIT

+ +
+
+ + + + +
#define LZMA_STREAM_INIT
+
+Value:
{ NULL, 0, 0, NULL, 0, 0, NULL, NULL, \
+
NULL, NULL, NULL, NULL, 0, 0, 0, 0, \
+
LZMA_RESERVED_ENUM, LZMA_RESERVED_ENUM }
+
+

Initialization for lzma_stream.

+

When you declare an instance of lzma_stream, you can immediately initialize it so that initialization functions know that no memory has been allocated yet:

+

lzma_stream strm = LZMA_STREAM_INIT;

+

If you need to initialize a dynamically allocated lzma_stream, you can use memset(strm_pointer, 0, sizeof(lzma_stream)). Strictly speaking, this violates the C standard since NULL may have different internal representation than zero, but it should be portable enough in practice. Anyway, for maximum portability, you can use something like this:

+

lzma_stream tmp = LZMA_STREAM_INIT; *strm = tmp;

+ +
+
+

Typedef Documentation

+ +

◆ lzma_bool

+ +
+
+ + + + +
typedef unsigned char lzma_bool
+
+ +

Boolean.

+

This is here because C89 doesn't have stdbool.h. To set a value for variables having type lzma_bool, you can use

    +
  • C99's `true' and `false' from stdbool.h;
    • +
  • C++'s internal `true' and `false'; or
    • +
  • integers one (true) and zero (false).
    • +
+ +
+
+ +

◆ lzma_internal

+ +
+
+ + + + +
typedef struct lzma_internal_s lzma_internal
+
+ +

Internal data structure.

+

The contents of this structure is not visible outside the library.

+ +
+
+

Enumeration Type Documentation

+ +

◆ lzma_reserved_enum

+ +
+
+ + + + +
enum lzma_reserved_enum
+
+ +

Type of reserved enumeration variable in structures.

+

To avoid breaking library ABI when new features are added, several structures contain extra variables that may be used in future. Since sizeof(enum) can be different than sizeof(int), and sizeof(enum) may even vary depending on the range of enumeration constants, we specify a separate type to be used for reserved enumeration variables. All enumeration constants in liblzma API will be non-negative and less than 128, which should guarantee that the ABI won't break even when new constants are added to existing enumerations.

+ +
+
+ +

◆ lzma_ret

+ +
+
+ + + + +
enum lzma_ret
+
+ +

Return values used by several functions in liblzma.

+

Check the descriptions of specific functions to find out which return values they can return. With some functions the return values may have more specific meanings than described here; those differences are described per-function basis.

+ + + + + + + + + + + + + + +
Enumerator
LZMA_OK 

Operation completed successfully.

+
LZMA_STREAM_END 

End of stream was reached.

+

In encoder, LZMA_SYNC_FLUSH, LZMA_FULL_FLUSH, or LZMA_FINISH was finished. In decoder, this indicates that all the data was successfully decoded.

+

In all cases, when LZMA_STREAM_END is returned, the last output bytes should be picked from strm->next_out.

+
LZMA_NO_CHECK 

Input stream has no integrity check.

+

This return value can be returned only if the LZMA_TELL_NO_CHECK flag was used when initializing the decoder. LZMA_NO_CHECK is just a warning, and the decoding can be continued normally.

+

It is possible to call lzma_get_check() immediately after lzma_code has returned LZMA_NO_CHECK. The result will naturally be LZMA_CHECK_NONE, but the possibility to call lzma_get_check() may be convenient in some applications.

+
LZMA_UNSUPPORTED_CHECK 

Cannot calculate the integrity check.

+

The usage of this return value is different in encoders and decoders.

+

Encoders can return this value only from the initialization function. If initialization fails with this value, the encoding cannot be done, because there's no way to produce output with the correct integrity check.

+

Decoders can return this value only from lzma_code() and only if the LZMA_TELL_UNSUPPORTED_CHECK flag was used when initializing the decoder. The decoding can still be continued normally even if the check type is unsupported, but naturally the check will not be validated, and possible errors may go undetected.

+

With decoder, it is possible to call lzma_get_check() immediately after lzma_code() has returned LZMA_UNSUPPORTED_CHECK. This way it is possible to find out what the unsupported Check ID was.

+
LZMA_GET_CHECK 

Integrity check type is now available.

+

This value can be returned only by the lzma_code() function and only if the decoder was initialized with the LZMA_TELL_ANY_CHECK flag. LZMA_GET_CHECK tells the application that it may now call lzma_get_check() to find out the Check ID. This can be used, for example, to implement a decoder that accepts only files that have strong enough integrity check.

+
LZMA_MEM_ERROR 

Cannot allocate memory.

+

Memory allocation failed, or the size of the allocation would be greater than SIZE_MAX.

+

Due to internal implementation reasons, the coding cannot be continued even if more memory were made available after LZMA_MEM_ERROR.

+
LZMA_MEMLIMIT_ERROR 

Memory usage limit was reached.

+

Decoder would need more memory than allowed by the specified memory usage limit. To continue decoding, the memory usage limit has to be increased with lzma_memlimit_set().

+

liblzma 5.2.6 and earlier had a bug in single-threaded .xz decoder (lzma_stream_decoder()) which made it impossible to continue decoding after LZMA_MEMLIMIT_ERROR even if the limit was increased using lzma_memlimit_set(). Other decoders worked correctly.

+
LZMA_FORMAT_ERROR 

File format not recognized.

+

The decoder did not recognize the input as supported file format. This error can occur, for example, when trying to decode .lzma format file with lzma_stream_decoder, because lzma_stream_decoder accepts only the .xz format.

+
LZMA_OPTIONS_ERROR 

Invalid or unsupported options.

+

Invalid or unsupported options, for example

    +
  • unsupported filter(s) or filter options; or
    • +
  • reserved bits set in headers (decoder only).
    • +
+

Rebuilding liblzma with more features enabled, or upgrading to a newer version of liblzma may help.

+
LZMA_DATA_ERROR 

Data is corrupt.

+

The usage of this return value is different in encoders and decoders. In both encoder and decoder, the coding cannot continue after this error.

+

Encoders return this if size limits of the target file format would be exceeded. These limits are huge, thus getting this error from an encoder is mostly theoretical. For example, the maximum compressed and uncompressed size of a .xz Stream is roughly 8 EiB (2^63 bytes).

+

Decoders return this error if the input data is corrupt. This can mean, for example, invalid CRC32 in headers or invalid check of uncompressed data.

+
LZMA_BUF_ERROR 

No progress is possible.

+

This error code is returned when the coder cannot consume any new input and produce any new output. The most common reason for this error is that the input stream being decoded is truncated or corrupt.

+

This error is not fatal. Coding can be continued normally by providing more input and/or more output space, if possible.

+

Typically the first call to lzma_code() that can do no progress returns LZMA_OK instead of LZMA_BUF_ERROR. Only the second consecutive call doing no progress will return LZMA_BUF_ERROR. This is intentional.

+

With zlib, Z_BUF_ERROR may be returned even if the application is doing nothing wrong, so apps will need to handle Z_BUF_ERROR specially. The above hack guarantees that liblzma never returns LZMA_BUF_ERROR to properly written applications unless the input file is truncated or corrupt. This should simplify the applications a little.

+
LZMA_PROG_ERROR 

Programming error.

+

This indicates that the arguments given to the function are invalid or the internal state of the decoder is corrupt.

    +
  • Function arguments are invalid or the structures pointed by the argument pointers are invalid e.g. if strm->next_out has been set to NULL and strm->avail_out > 0 when calling lzma_code().
    • +
  • lzma_* functions have been called in wrong order e.g. lzma_code() was called right after lzma_end().
    • +
  • If errors occur randomly, the reason might be flaky hardware.
    • +
+

If you think that your code is correct, this error code can be a sign of a bug in liblzma. See the documentation how to report bugs.

+
LZMA_SEEK_NEEDED 

Request to change the input file position.

+

Some coders can do random access in the input file. The initialization functions of these coders take the file size as an argument. No other coders can return LZMA_SEEK_NEEDED.

+

When this value is returned, the application must seek to the file position given in lzma_stream.seek_pos. This value is guaranteed to never exceed the file size that was specified at the coder initialization.

+

After seeking the application should read new input and pass it normally via lzma_stream.next_in and .avail_in.

+
+ +
+
+ +

◆ lzma_action

+ +
+
+ + + + +
enum lzma_action
+
+ +

The `action' argument for lzma_code()

+

After the first use of LZMA_SYNC_FLUSH, LZMA_FULL_FLUSH, LZMA_FULL_BARRIER, or LZMA_FINISH, the same `action' must be used until lzma_code() returns LZMA_STREAM_END. Also, the amount of input (that is, strm->avail_in) must not be modified by the application until lzma_code() returns LZMA_STREAM_END. Changing the `action' or modifying the amount of input will make lzma_code() return LZMA_PROG_ERROR.

+ + + + + + +
Enumerator
LZMA_RUN 

Continue coding.

+

Encoder: Encode as much input as possible. Some internal buffering will probably be done (depends on the filter chain in use), which causes latency: the input used won't usually be decodeable from the output of the same lzma_code() call.

+

Decoder: Decode as much input as possible and produce as much output as possible.

+
LZMA_SYNC_FLUSH 

Make all the input available at output.

+

Normally the encoder introduces some latency. LZMA_SYNC_FLUSH forces all the buffered data to be available at output without resetting the internal state of the encoder. This way it is possible to use compressed stream for example for communication over network.

+

Only some filters support LZMA_SYNC_FLUSH. Trying to use LZMA_SYNC_FLUSH with filters that don't support it will make lzma_code() return LZMA_OPTIONS_ERROR. For example, LZMA1 doesn't support LZMA_SYNC_FLUSH but LZMA2 does.

+

Using LZMA_SYNC_FLUSH very often can dramatically reduce the compression ratio. With some filters (for example, LZMA2), fine-tuning the compression options may help mitigate this problem significantly (for example, match finder with LZMA2).

+

Decoders don't support LZMA_SYNC_FLUSH.

+
LZMA_FULL_FLUSH 

Finish encoding of the current Block.

+

All the input data going to the current Block must have been given to the encoder (the last bytes can still be pending in *next_in). Call lzma_code() with LZMA_FULL_FLUSH until it returns LZMA_STREAM_END. Then continue normally with LZMA_RUN or finish the Stream with LZMA_FINISH.

+

This action is currently supported only by Stream encoder and easy encoder (which uses Stream encoder). If there is no unfinished Block, no empty Block is created.

+
LZMA_FULL_BARRIER 

Finish encoding of the current Block.

+

This is like LZMA_FULL_FLUSH except that this doesn't necessarily wait until all the input has been made available via the output buffer. That is, lzma_code() might return LZMA_STREAM_END as soon as all the input has been consumed (avail_in == 0).

+

LZMA_FULL_BARRIER is useful with a threaded encoder if one wants to split the .xz Stream into Blocks at specific offsets but doesn't care if the output isn't flushed immediately. Using LZMA_FULL_BARRIER allows keeping the threads busy while LZMA_FULL_FLUSH would make lzma_code() wait until all the threads have finished until more data could be passed to the encoder.

+

With a lzma_stream initialized with the single-threaded lzma_stream_encoder() or lzma_easy_encoder(), LZMA_FULL_BARRIER is an alias for LZMA_FULL_FLUSH.

+
LZMA_FINISH 

Finish the coding operation.

+

All the input data must have been given to the encoder (the last bytes can still be pending in next_in). Call lzma_code() with LZMA_FINISH until it returns LZMA_STREAM_END. Once LZMA_FINISH has been used, the amount of input must no longer be changed by the application.

+

When decoding, using LZMA_FINISH is optional unless the LZMA_CONCATENATED flag was used when the decoder was initialized. When LZMA_CONCATENATED was not used, the only effect of LZMA_FINISH is that the amount of input must not be changed just like in the encoder.

+

Function Documentation

+ +

◆ lzma_code()

+ +
+
+ + + + + + + + + + + + + + + + + + +
lzma_ret lzma_code (lzma_stream * strm,
lzma_action action 
)
+
+ +

Encode or decode data.

+

Once the lzma_stream has been successfully initialized (e.g. with lzma_stream_encoder()), the actual encoding or decoding is done using this function. The application has to update strm->next_in, strm->avail_in, strm->next_out, and strm->avail_out to pass input to and get output from liblzma.

+

See the description of the coder-specific initialization function to find out what `action' values are supported by the coder.

+
Parameters
+ + + +
strmPointer to lzma_stream that is at least initialized with LZMA_STREAM_INIT.
actionAction for this function to take. Must be a valid lzma_action enum value.
+
+
+
Returns
Any valid lzma_ret. See the lzma_ret enum description for more information.
+ +
+
+ +

◆ lzma_end()

+ +
+
+ + + + + + + + +
void lzma_end (lzma_stream * strm)
+
+ +

Free memory allocated for the coder data structures.

+

After lzma_end(strm), strm->internal is guaranteed to be NULL. No other members of the lzma_stream structure are touched.

+
Note
zlib indicates an error if application end()s unfinished stream structure. liblzma doesn't do this, and assumes that application knows what it is doing.
+
Parameters
+ + +
strmPointer to lzma_stream that is at least initialized with LZMA_STREAM_INIT.
+
+
+ +
+
+ +

◆ lzma_get_progress()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + +
void lzma_get_progress (lzma_stream * strm,
uint64_t * progress_in,
uint64_t * progress_out 
)
+
+ +

Get progress information.

+

In single-threaded mode, applications can get progress information from strm->total_in and strm->total_out. In multi-threaded mode this is less useful because a significant amount of both input and output data gets buffered internally by liblzma. This makes total_in and total_out give misleading information and also makes the progress indicator updates non-smooth.

+

This function gives realistic progress information also in multi-threaded mode by taking into account the progress made by each thread. In single-threaded mode *progress_in and *progress_out are set to strm->total_in and strm->total_out, respectively.

+
Parameters
+ + + + +
strmPointer to lzma_stream that is at least initialized with LZMA_STREAM_INIT.
[out]progress_inPointer to the number of input bytes processed.
[out]progress_outPointer to the number of output bytes processed.
+
+
+ +
+
+ +

◆ lzma_memusage()

+ +
+
+ + + + + + + + +
uint64_t lzma_memusage (const lzma_stream * strm)
+
+ +

Get the memory usage of decoder filter chain.

+

This function is currently supported only when *strm has been initialized with a function that takes a memlimit argument. With other functions, you should use e.g. lzma_raw_encoder_memusage() or lzma_raw_decoder_memusage() to estimate the memory requirements.

+

This function is useful e.g. after LZMA_MEMLIMIT_ERROR to find out how big the memory usage limit should have been to decode the input. Note that this may give misleading information if decoding .xz Streams that have multiple Blocks, because each Block can have different memory requirements.

+
Parameters
+ + +
strmPointer to lzma_stream that is at least initialized with LZMA_STREAM_INIT.
+
+
+
Returns
How much memory is currently allocated for the filter decoders. If no filter chain is currently allocated, some non-zero value is still returned, which is less than or equal to what any filter chain would indicate as its memory requirement.
+

If this function isn't supported by *strm or some other error occurs, zero is returned.

+ +
+
+ +

◆ lzma_memlimit_get()

+ +
+
+ + + + + + + + +
uint64_t lzma_memlimit_get (const lzma_stream * strm)
+
+ +

Get the current memory usage limit.

+

This function is supported only when *strm has been initialized with a function that takes a memlimit argument.

+
Parameters
+ + +
strmPointer to lzma_stream that is at least initialized with LZMA_STREAM_INIT.
+
+
+
Returns
On success, the current memory usage limit is returned (always non-zero). On error, zero is returned.
+ +
+
+ +

◆ lzma_memlimit_set()

+ +
+
+ + + + + + + + + + + + + + + + + + +
lzma_ret lzma_memlimit_set (lzma_stream * strm,
uint64_t memlimit 
)
+
+ +

Set the memory usage limit.

+

This function is supported only when *strm has been initialized with a function that takes a memlimit argument.

+

liblzma 5.2.3 and earlier has a bug where memlimit value of 0 causes this function to do nothing (leaving the limit unchanged) and still return LZMA_OK. Later versions treat 0 as if 1 had been specified (so lzma_memlimit_get() will return 1 even if you specify 0 here).

+

liblzma 5.2.6 and earlier had a bug in single-threaded .xz decoder (lzma_stream_decoder()) which made it impossible to continue decoding after LZMA_MEMLIMIT_ERROR even if the limit was increased using lzma_memlimit_set(). Other decoders worked correctly.

+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK: New memory usage limit successfully set.
    • +
  • LZMA_MEMLIMIT_ERROR: The new limit is too small. The limit was not changed.
    • +
  • LZMA_PROG_ERROR: Invalid arguments, e.g. *strm doesn't support memory usage limit.
    • +

Macro Definition Documentation

+ +

◆ lzma_block_header_size_decode

+ +
+
+ + + + + + + + +
#define lzma_block_header_size_decode( b)   (((uint32_t)(b) + 1) * 4)
+
+ +

Decode the Block Header Size field.

+

To decode Block Header using lzma_block_header_decode(), the size of the Block Header has to be known and stored into lzma_block.header_size. The size can be calculated from the first byte of a Block using this macro. Note that if the first byte is 0x00, it indicates beginning of Index; use this macro only when the byte is not 0x00.

+

There is no encoding macro because lzma_block_header_size() and lzma_block_header_encode() should be used.

+ +
+
+

Function Documentation

+ +

◆ lzma_block_header_size()

+ +
+
+ + + + + + + + +
lzma_ret lzma_block_header_size (lzma_block * block)
+
+ +

Calculate Block Header Size.

+

Calculate the minimum size needed for the Block Header field using the settings specified in the lzma_block structure. Note that it is OK to increase the calculated header_size value as long as it is a multiple of four and doesn't exceed LZMA_BLOCK_HEADER_SIZE_MAX. Increasing header_size just means that lzma_block_header_encode() will add Header Padding.

+
Note
This doesn't check that all the options are valid i.e. this may return LZMA_OK even if lzma_block_header_encode() or lzma_block_encoder() would fail. If you want to validate the filter chain, consider using lzma_memlimit_encoder() which as a side-effect validates the filter chain.
+
Parameters
+ + +
blockBlock options
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK: Size calculated successfully and stored to block->header_size.
    • +
  • LZMA_OPTIONS_ERROR: Unsupported version, filters or filter options.
    • +
  • LZMA_PROG_ERROR: Invalid values like compressed_size == 0.
    • +
+
+ +
+
+ +

◆ lzma_block_header_encode()

+ +
+
+ + + + + + + + + + + + + + + + + + +
lzma_ret lzma_block_header_encode (const lzma_block * block,
uint8_t * out 
)
+
+ +

Encode Block Header.

+

The caller must have calculated the size of the Block Header already with lzma_block_header_size(). If a value larger than the one calculated by lzma_block_header_size() is used, the Block Header will be padded to the specified size.

+
Parameters
+ + + +
blockBlock options to be encoded.
[out]outBeginning of the output buffer. This must be at least block->header_size bytes.
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK: Encoding was successful. block->header_size bytes were written to output buffer.
    • +
  • LZMA_OPTIONS_ERROR: Invalid or unsupported options.
    • +
  • LZMA_PROG_ERROR: Invalid arguments, for example block->header_size is invalid or block->filters is NULL.
    • +
+
+ +
+
+ +

◆ lzma_block_header_decode()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + +
lzma_ret lzma_block_header_decode (lzma_block * block,
const lzma_allocator * allocator,
const uint8_t * in 
)
+
+ +

Decode Block Header.

+

block->version should (usually) be set to the highest value supported by the application. If the application sets block->version to a value higher than supported by the current liblzma version, this function will downgrade block->version to the highest value supported by it. Thus one should check the value of block->version after calling this function if block->version was set to a non-zero value and the application doesn't otherwise know that the liblzma version being used is new enough to support the specified block->version.

+

The size of the Block Header must have already been decoded with lzma_block_header_size_decode() macro and stored to block->header_size.

+

The integrity check type from Stream Header must have been stored to block->check.

+

block->filters must have been allocated, but they don't need to be initialized (possible existing filter options are not freed).

+
Parameters
+ + + + +
[out]blockDestination for Block options
allocatorlzma_allocator for custom allocator functions. Set to NULL to use malloc() (and also free() if an error occurs).
inBeginning of the input buffer. This must be at least block->header_size bytes.
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK: Decoding was successful. block->header_size bytes were read from the input buffer.
    • +
  • LZMA_OPTIONS_ERROR: The Block Header specifies some unsupported options such as unsupported filters. This can happen also if block->version was set to a too low value compared to what would be required to properly represent the information stored in the Block Header.
    • +
  • LZMA_DATA_ERROR: Block Header is corrupt, for example, the CRC32 doesn't match.
    • +
  • LZMA_PROG_ERROR: Invalid arguments, for example block->header_size is invalid or block->filters is NULL.
    • +
+
+ +
+
+ +

◆ lzma_block_compressed_size()

+ +
+
+ + + + + + + + + + + + + + + + + + +
lzma_ret lzma_block_compressed_size (lzma_block * block,
lzma_vli unpadded_size 
)
+
+ +

Validate and set Compressed Size according to Unpadded Size.

+

Block Header stores Compressed Size, but Index has Unpadded Size. If the application has already parsed the Index and is now decoding Blocks, it can calculate Compressed Size from Unpadded Size. This function does exactly that with error checking:

+
    +
  • Compressed Size calculated from Unpadded Size must be positive integer, that is, Unpadded Size must be big enough that after Block Header and Check fields there's still at least one byte for Compressed Size.
    • +
  • If Compressed Size was present in Block Header, the new value calculated from Unpadded Size is compared against the value from Block Header.
    • +
+
Note
This function must be called _after_ decoding the Block Header field so that it can properly validate Compressed Size if it was present in Block Header.
+
Parameters
+ + + +
blockBlock options: block->header_size must already be set with lzma_block_header_size().
unpadded_sizeUnpadded Size from the Index field in bytes
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK: block->compressed_size was set successfully.
    • +
  • LZMA_DATA_ERROR: unpadded_size is too small compared to block->header_size and lzma_check_size(block->check).
    • +
  • LZMA_PROG_ERROR: Some values are invalid. For example, block->header_size must be a multiple of four and between 8 and 1024 inclusive.
    • +
+
+ +
+
+ +

◆ lzma_block_unpadded_size()

+ +
+
+ + + + + + + + +
lzma_vli lzma_block_unpadded_size (const lzma_block * block)
+
+ +

Calculate Unpadded Size.

+

The Index field stores Unpadded Size and Uncompressed Size. The latter can be taken directly from the lzma_block structure after coding a Block, but Unpadded Size needs to be calculated from Block Header Size, Compressed Size, and size of the Check field. This is where this function is needed.

+
Parameters
+ + +
blockBlock options: block->header_size must already be set with lzma_block_header_size().
+
+
+
Returns
Unpadded Size on success, or zero on error.
+ +
+
+ +

◆ lzma_block_total_size()

+ +
+
+ + + + + + + + +
lzma_vli lzma_block_total_size (const lzma_block * block)
+
+ +

Calculate the total encoded size of a Block.

+

This is equivalent to lzma_block_unpadded_size() except that the returned value includes the size of the Block Padding field.

+
Parameters
+ + +
blockBlock options: block->header_size must already be set with lzma_block_header_size().
+
+
+
Returns
On success, total encoded size of the Block. On error, zero is returned.
+ +
+
+ +

◆ lzma_block_encoder()

+ +
+
+ + + + + + + + + + + + + + + + + + +
lzma_ret lzma_block_encoder (lzma_stream * strm,
lzma_block * block 
)
+
+ +

Initialize .xz Block encoder.

+

Valid actions for lzma_code() are LZMA_RUN, LZMA_SYNC_FLUSH (only if the filter chain supports it), and LZMA_FINISH.

+

The Block encoder encodes the Block Data, Block Padding, and Check value. It does NOT encode the Block Header which can be encoded with lzma_block_header_encode().

+
Parameters
+ + + +
strmPointer to lzma_stream that is at least initialized with LZMA_STREAM_INIT.
blockBlock options: block->version, block->check, and block->filters must have been initialized.
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK: All good, continue with lzma_code().
    • +
  • LZMA_MEM_ERROR
    • +
  • LZMA_OPTIONS_ERROR
    • +
  • LZMA_UNSUPPORTED_CHECK: block->check specifies a Check ID that is not supported by this build of liblzma. Initializing the encoder failed.
    • +
  • LZMA_PROG_ERROR
    • +
+
+ +
+
+ +

◆ lzma_block_decoder()

+ +
+
+ + + + + + + + + + + + + + + + + + +
lzma_ret lzma_block_decoder (lzma_stream * strm,
lzma_block * block 
)
+
+ +

Initialize .xz Block decoder.

+

Valid actions for lzma_code() are LZMA_RUN and LZMA_FINISH. Using LZMA_FINISH is not required. It is supported only for convenience.

+

The Block decoder decodes the Block Data, Block Padding, and Check value. It does NOT decode the Block Header which can be decoded with lzma_block_header_decode().

+
Parameters
+ + + +
strmPointer to lzma_stream that is at least initialized with LZMA_STREAM_INIT.
blockBlock options
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK: All good, continue with lzma_code().
    • +
  • LZMA_PROG_ERROR
    • +
  • LZMA_MEM_ERROR
    • +
+
+ +
+
+ +

◆ lzma_block_buffer_bound()

+ +
+
+ + + + + + + + +
size_t lzma_block_buffer_bound (size_t uncompressed_size)
+
+ +

Calculate maximum output size for single-call Block encoding.

+

This is equivalent to lzma_stream_buffer_bound() but for .xz Blocks. See the documentation of lzma_stream_buffer_bound().

+
Parameters
+ + +
uncompressed_sizeSize of the data to be encoded with the single-call Block encoder.
+
+
+
Returns
Maximum output size in bytes for single-call Block encoding.
+ +
+
+ +

◆ lzma_block_buffer_encode()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
lzma_ret lzma_block_buffer_encode (lzma_block * block,
const lzma_allocator * allocator,
const uint8_t * in,
size_t in_size,
uint8_t * out,
size_t * out_pos,
size_t out_size 
)
+
+ +

Single-call .xz Block encoder.

+

In contrast to the multi-call encoder initialized with lzma_block_encoder(), this function encodes also the Block Header. This is required to make it possible to write appropriate Block Header also in case the data isn't compressible, and different filter chain has to be used to encode the data in uncompressed form using uncompressed chunks of the LZMA2 filter.

+

When the data isn't compressible, header_size, compressed_size, and uncompressed_size are set just like when the data was compressible, but it is possible that header_size is too small to hold the filter chain specified in block->filters, because that isn't necessarily the filter chain that was actually used to encode the data. lzma_block_unpadded_size() still works normally, because it doesn't read the filters array.

+
Parameters
+ + + + + + + + +
blockBlock options: block->version, block->check, and block->filters must have been initialized.
allocatorlzma_allocator for custom allocator functions. Set to NULL to use malloc() and free().
inBeginning of the input buffer
in_sizeSize of the input buffer
[out]outBeginning of the output buffer
[out]out_posThe next byte will be written to out[*out_pos]. *out_pos is updated only if encoding succeeds.
out_sizeSize of the out buffer; the first byte into which no data is written to is out[out_size].
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK: Encoding was successful.
    • +
  • LZMA_BUF_ERROR: Not enough output buffer space.
    • +
  • LZMA_UNSUPPORTED_CHECK
    • +
  • LZMA_OPTIONS_ERROR
    • +
  • LZMA_MEM_ERROR
    • +
  • LZMA_DATA_ERROR
    • +
  • LZMA_PROG_ERROR
    • +
+
+ +
+
+ +

◆ lzma_block_uncomp_encode()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
lzma_ret lzma_block_uncomp_encode (lzma_block * block,
const uint8_t * in,
size_t in_size,
uint8_t * out,
size_t * out_pos,
size_t out_size 
)
+
+ +

Single-call uncompressed .xz Block encoder.

+

This is like lzma_block_buffer_encode() except this doesn't try to compress the data and instead encodes the data using LZMA2 uncompressed chunks. The required output buffer size can be determined with lzma_block_buffer_bound().

+

Since the data won't be compressed, this function ignores block->filters. This function doesn't take lzma_allocator because this function doesn't allocate any memory from the heap.

+
Parameters
+ + + + + + + +
blockBlock options: block->version, block->check, and block->filters must have been initialized.
inBeginning of the input buffer
in_sizeSize of the input buffer
[out]outBeginning of the output buffer
[out]out_posThe next byte will be written to out[*out_pos]. *out_pos is updated only if encoding succeeds.
out_sizeSize of the out buffer; the first byte into which no data is written to is out[out_size].
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK: Encoding was successful.
    • +
  • LZMA_BUF_ERROR: Not enough output buffer space.
    • +
  • LZMA_UNSUPPORTED_CHECK
    • +
  • LZMA_OPTIONS_ERROR
    • +
  • LZMA_MEM_ERROR
    • +
  • LZMA_DATA_ERROR
    • +
  • LZMA_PROG_ERROR
    • +
+
+ +
+
+ +

◆ lzma_block_buffer_decode()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
lzma_ret lzma_block_buffer_decode (lzma_block * block,
const lzma_allocator * allocator,
const uint8_t * in,
size_t * in_pos,
size_t in_size,
uint8_t * out,
size_t * out_pos,
size_t out_size 
)
+
+ +

Single-call .xz Block decoder.

+

This is single-call equivalent of lzma_block_decoder(), and requires that the caller has already decoded Block Header and checked its memory usage.

+

+ + + + + + + + + +
blockBlock options
allocatorlzma_allocator for custom allocator functions. Set to NULL to use malloc() and free().
inBeginning of the input buffer
in_posThe next byte will be read from in[*in_pos]. *in_pos is updated only if decoding succeeds.

◆ LZMA_CHECK_ID_MAX

+ +
+
+ + + + +
#define LZMA_CHECK_ID_MAX   15
+
+ +

Maximum valid Check ID.

+

The .xz file format specification specifies 16 Check IDs (0-15). Some of them are only reserved, that is, no actual Check algorithm has been assigned. When decoding, liblzma still accepts unknown Check IDs for future compatibility. If a valid but unsupported Check ID is detected, liblzma can indicate a warning; see the flags LZMA_TELL_NO_CHECK, LZMA_TELL_UNSUPPORTED_CHECK, and LZMA_TELL_ANY_CHECK in container.h.

+ +
+
+

Enumeration Type Documentation

+ +

◆ lzma_check

+ +
+
+ + + + +
enum lzma_check
+
+ +

+

The .xz format supports multiple types of checks that are calculated from the uncompressed data. They vary in both speed and ability to detect errors.

+ + + + + +
Enumerator
LZMA_CHECK_NONE 

No Check is calculated.

+

Size of the Check field: 0 bytes

+
LZMA_CHECK_CRC32 

CRC32 using the polynomial from the IEEE 802.3 standard

+

Size of the Check field: 4 bytes

+
LZMA_CHECK_CRC64 

CRC64 using the polynomial from the ECMA-182 standard

+

Size of the Check field: 8 bytes

+
LZMA_CHECK_SHA256 

SHA-256

+

Size of the Check field: 32 bytes

+
+ +
+

◆ lzma_check_is_supported()

+ +
+
+ + + + + + + + +
lzma_bool lzma_check_is_supported (lzma_check check) const
+
+ +

Test if the given Check ID is supported.

+

LZMA_CHECK_NONE and LZMA_CHECK_CRC32 are always supported (even if liblzma is built with limited features).

+
Note
It is safe to call this with a value that is not in the range [0, 15]; in that case the return value is always false.
+
Parameters
+ + +
checkCheck ID
+
+
+
Returns
lzma_bool:
    +
  • true if Check ID is supported by this liblzma build.
    • +
  • false otherwise.
    • +
+
+ +
+
+ +

◆ lzma_check_size()

+ +
+
+ + + + + + + + +
uint32_t lzma_check_size (lzma_check check) const
+
+ +

Get the size of the Check field with the given Check ID.

+

Although not all Check IDs have a check algorithm associated, the size of every Check is already frozen. This function returns the size (in bytes) of the Check field with the specified Check ID. The values are: { 0, 4, 4, 4, 8, 8, 8, 16, 16, 16, 32, 32, 32, 64, 64, 64 }

+
Parameters
+ + +
checkCheck ID
+
+
+
Returns
Size of the Check field in bytes. If the argument is not in the range [0, 15], UINT32_MAX is returned.
+ +
+
+ +

◆ lzma_crc32()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + +
uint32_t lzma_crc32 (const uint8_t * buf,
size_t size,
uint32_t crc 
)
+
+ +

Calculate CRC32.

+

Calculate CRC32 using the polynomial from the IEEE 802.3 standard.

+
Parameters
+ + + + +
bufPointer to the input buffer
sizeSize of the input buffer
crcPreviously returned CRC value. This is used to calculate the CRC of a big buffer in smaller chunks. Set to zero when starting a new calculation.
+
+
+
Returns
Updated CRC value, which can be passed to this function again to continue CRC calculation.
+ +
+
+ +

◆ lzma_crc64()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + +
uint64_t lzma_crc64 (const uint8_t * buf,
size_t size,
uint64_t crc 
)
+
+ +

Calculate CRC64.

+

Calculate CRC64 using the polynomial from the ECMA-182 standard.

+

This function is used similarly to lzma_crc32().

+
Parameters
+ + + + +
bufPointer to the input buffer
sizeSize of the input buffer
crcPreviously returned CRC value. This is used to calculate the CRC of a big buffer in smaller chunks. Set to zero when starting a new calculation.
+
+
+
Returns
Updated CRC value, which can be passed to this function again to continue CRC calculation.
+ +
+
+ +

◆ lzma_get_check()

+ +
+
+ + + + + + + + +
lzma_check lzma_get_check (const lzma_stream * strm)
+
+ +

Get the type of the integrity check.

+

This function can be called only immediately after lzma_code() has returned LZMA_NO_CHECK, LZMA_UNSUPPORTED_CHECK, or LZMA_GET_CHECK. Calling this function in any other situation has undefined behavior.

+
Parameters
+ + +
strmPointer to lzma_stream meeting the above conditions.
+
+
+
Returns
Check ID in the lzma_stream, or undefined if called improperly.

Macro Definition Documentation

+ +

◆ LZMA_PRESET_DEFAULT

+ +
+
+ + + + +
#define LZMA_PRESET_DEFAULT   UINT32_C(6)
+
+ +

Default compression preset.

+

It's not straightforward to recommend a default preset, because in some cases keeping the resource usage relatively low is more important that getting the maximum compression ratio.

+ +
+
+ +

◆ LZMA_PRESET_LEVEL_MASK

+ +
+
+ + + + +
#define LZMA_PRESET_LEVEL_MASK   UINT32_C(0x1F)
+
+ +

Mask for preset level.

+

This is useful only if you need to extract the level from the preset variable. That should be rare.

+ +
+
+ +

◆ LZMA_PRESET_EXTREME

+ +
+
+ + + + +
#define LZMA_PRESET_EXTREME   (UINT32_C(1) << 31)
+
+ +

Extreme compression preset.

+

This flag modifies the preset to make the encoding significantly slower while improving the compression ratio only marginally. This is useful when you don't mind spending time to get as small result as possible.

+

This flag doesn't affect the memory usage requirements of the decoder (at least not significantly). The memory usage of the encoder may be increased a little but only at the lowest preset levels (0-3).

+ +
+
+ +

◆ LZMA_TELL_NO_CHECK

+ +
+
+ + + + +
#define LZMA_TELL_NO_CHECK   UINT32_C(0x01)
+
+

This flag makes lzma_code() return LZMA_NO_CHECK if the input stream being decoded has no integrity check. Note that when used with lzma_auto_decoder(), all .lzma files will trigger LZMA_NO_CHECK if LZMA_TELL_NO_CHECK is used.

+ +
+
+ +

◆ LZMA_TELL_UNSUPPORTED_CHECK

+ +
+
+ + + + +
#define LZMA_TELL_UNSUPPORTED_CHECK   UINT32_C(0x02)
+
+

This flag makes lzma_code() return LZMA_UNSUPPORTED_CHECK if the input stream has an integrity check, but the type of the integrity check is not supported by this liblzma version or build. Such files can still be decoded, but the integrity check cannot be verified.

+ +
+
+ +

◆ LZMA_TELL_ANY_CHECK

+ +
+
+ + + + +
#define LZMA_TELL_ANY_CHECK   UINT32_C(0x04)
+
+

This flag makes lzma_code() return LZMA_GET_CHECK as soon as the type of the integrity check is known. The type can then be got with lzma_get_check().

+ +
+
+ +

◆ LZMA_IGNORE_CHECK

+ +
+
+ + + + +
#define LZMA_IGNORE_CHECK   UINT32_C(0x10)
+
+

This flag makes lzma_code() not calculate and verify the integrity check of the compressed data in .xz files. This means that invalid integrity check values won't be detected and LZMA_DATA_ERROR won't be returned in such cases.

+

This flag only affects the checks of the compressed data itself; the CRC32 values in the .xz headers will still be verified normally.

+

Don't use this flag unless you know what you are doing. Possible reasons to use this flag:

+
    +
  • Trying to recover data from a corrupt .xz file.
    • +
  • Speeding up decompression, which matters mostly with SHA-256 or with files that have compressed extremely well. It's recommended to not use this flag for this purpose unless the file integrity is verified externally in some other way.
    • +
+

Support for this flag was added in liblzma 5.1.4beta.

+ +
+
+ +

◆ LZMA_CONCATENATED

+ +
+
+ + + + +
#define LZMA_CONCATENATED   UINT32_C(0x08)
+
+

This flag enables decoding of concatenated files with file formats that allow concatenating compressed files as is. From the formats currently supported by liblzma, only the .xz and .lz formats allow concatenated files. Concatenated files are not allowed with the legacy .lzma format.

+

This flag also affects the usage of the `action' argument for lzma_code(). When LZMA_CONCATENATED is used, lzma_code() won't return LZMA_STREAM_END unless LZMA_FINISH is used as `action'. Thus, the application has to set LZMA_FINISH in the same way as it does when encoding.

+

If LZMA_CONCATENATED is not used, the decoders still accept LZMA_FINISH as `action' for lzma_code(), but the usage of LZMA_FINISH isn't required.

+ +
+
+ +

◆ LZMA_FAIL_FAST

+ +
+
+ + + + +
#define LZMA_FAIL_FAST   UINT32_C(0x20)
+
+

This flag makes the threaded decoder report errors (like LZMA_DATA_ERROR) as soon as they are detected. This saves time when the application has no interest in a partially decompressed truncated or corrupt file. Note that due to timing randomness, if the same truncated or corrupt input is decompressed multiple times with this flag, a different amount of output may be produced by different runs, and even the error code might vary.

+

When using LZMA_FAIL_FAST, it is recommended to use LZMA_FINISH to tell the decoder when no more input will be coming because it can help fast detection and reporting of truncated files. Note that in this situation truncated files might be diagnosed with LZMA_DATA_ERROR instead of LZMA_OK or LZMA_BUF_ERROR!

+

Without this flag the threaded decoder will provide as much output as possible at first and then report the pending error. This default behavior matches the single-threaded decoder and provides repeatable behavior with truncated or corrupt input. There are a few special cases where the behavior can still differ like memory allocation failures (LZMA_MEM_ERROR).

+

Single-threaded decoders currently ignore this flag.

+

Support for this flag was added in liblzma 5.3.3alpha. Note that in older versions this flag isn't supported (LZMA_OPTIONS_ERROR) even by functions that ignore this flag in newer liblzma versions.

◆ lzma_easy_encoder_memusage()

+ +
+
+ + + + + + + + +
uint64_t lzma_easy_encoder_memusage (uint32_t preset)
+
+ +

Calculate approximate memory usage of easy encoder.

+

This function is a wrapper for lzma_raw_encoder_memusage().

+
Parameters
+ + +
presetCompression preset (level and possible flags)
+
+
+
Returns
Number of bytes of memory required for the given preset when encoding or UINT64_MAX on error.
+ +
+
+ +

◆ lzma_easy_decoder_memusage()

+ +
+
+ + + + + + + + +
uint64_t lzma_easy_decoder_memusage (uint32_t preset)
+
+ +

Calculate approximate decoder memory usage of a preset.

+

This function is a wrapper for lzma_raw_decoder_memusage().

+
Parameters
+ + +
presetCompression preset (level and possible flags)
+
+
+
Returns
Number of bytes of memory required to decompress a file that was compressed using the given preset or UINT64_MAX on error.
+ +
+
+ +

◆ lzma_easy_encoder()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + +
lzma_ret lzma_easy_encoder (lzma_stream * strm,
uint32_t preset,
lzma_check check 
)
+
+ +

Initialize .xz Stream encoder using a preset number.

+

This function is intended for those who just want to use the basic features of liblzma (that is, most developers out there).

+

If initialization fails (return value is not LZMA_OK), all the memory allocated for *strm by liblzma is always freed. Thus, there is no need to call lzma_end() after failed initialization.

+

If initialization succeeds, use lzma_code() to do the actual encoding. Valid values for `action' (the second argument of lzma_code()) are LZMA_RUN, LZMA_SYNC_FLUSH, LZMA_FULL_FLUSH, and LZMA_FINISH. In future, there may be compression levels or flags that don't support LZMA_SYNC_FLUSH.

+
Parameters
+ + + + +
strmPointer to lzma_stream that is at least initialized with LZMA_STREAM_INIT.
presetCompression preset to use. A preset consist of level number and zero or more flags. Usually flags aren't used, so preset is simply a number [0, 9] which match the options -0 ... -9 of the xz command line tool. Additional flags can be be set using bitwise-or with the preset level number, e.g. 6 | LZMA_PRESET_EXTREME.
checkIntegrity check type to use. See check.h for available checks. The xz command line tool defaults to LZMA_CHECK_CRC64, which is a good choice if you are unsure. LZMA_CHECK_CRC32 is good too as long as the uncompressed file is not many gigabytes.
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK: Initialization succeeded. Use lzma_code() to encode your data.
    • +
  • LZMA_MEM_ERROR: Memory allocation failed.
    • +
  • LZMA_OPTIONS_ERROR: The given compression preset is not supported by this build of liblzma.
    • +
  • LZMA_UNSUPPORTED_CHECK: The given check type is not supported by this liblzma build.
    • +
  • LZMA_PROG_ERROR: One or more of the parameters have values that will never be valid. For example, strm == NULL.

◆ lzma_stream_encoder_mt_memusage()

+ +
+
+ + + + + + + + +
uint64_t lzma_stream_encoder_mt_memusage (const lzma_mt * options)
+
+ +

Calculate approximate memory usage of multithreaded .xz encoder.

+

Since doing the encoding in threaded mode doesn't affect the memory requirements of single-threaded decompressor, you can use lzma_easy_decoder_memusage(options->preset) or lzma_raw_decoder_memusage(options->filters) to calculate the decompressor memory requirements.

+
Parameters
+ + +
optionsCompression options
+
+
+
Returns
Number of bytes of memory required for encoding with the given options. If an error occurs, for example due to unsupported preset or filter chain, UINT64_MAX is returned.
+ +
+
+ +

◆ lzma_stream_encoder_mt()

+ +
+
+ + + + + + + + + + + + + + + + + + +
lzma_ret lzma_stream_encoder_mt (lzma_stream * strm,
const lzma_mt * options 
)
+
+ +

Initialize multithreaded .xz Stream encoder.

+

This provides the functionality of lzma_easy_encoder() and lzma_stream_encoder() as a single function for multithreaded use.

+

The supported actions for lzma_code() are LZMA_RUN, LZMA_FULL_FLUSH, LZMA_FULL_BARRIER, and LZMA_FINISH. Support for LZMA_SYNC_FLUSH might be added in the future.

+
Parameters
+ + + +
strmPointer to lzma_stream that is at least initialized with LZMA_STREAM_INIT.
optionsPointer to multithreaded compression options
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK
    • +
  • LZMA_MEM_ERROR
    • +
  • LZMA_UNSUPPORTED_CHECK
    • +
  • LZMA_OPTIONS_ERROR
    • +
  • LZMA_PROG_ERROR
    • +
+
+ +
+
+ +

◆ lzma_alone_encoder()

+ +
+
+ + + + + + + + + + + + + + + + + + +
lzma_ret lzma_alone_encoder (lzma_stream * strm,
const lzma_options_lzma * options 
)
+
+ +

Initialize .lzma encoder (legacy file format)

+

The .lzma format is sometimes called the LZMA_Alone format, which is the reason for the name of this function. The .lzma format supports only the LZMA1 filter. There is no support for integrity checks like CRC32.

+

Use this function if and only if you need to create files readable by legacy LZMA tools such as LZMA Utils 4.32.x. Moving to the .xz format is strongly recommended.

+

The valid action values for lzma_code() are LZMA_RUN and LZMA_FINISH. No kind of flushing is supported, because the file format doesn't make it possible.

+
Parameters
+ + + +
strmPointer to lzma_stream that is at least initialized with LZMA_STREAM_INIT.
optionsPointer to encoder options
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK
    • +
  • LZMA_MEM_ERROR
    • +
  • LZMA_OPTIONS_ERROR
    • +
  • LZMA_PROG_ERROR
    • +
+
+ +
+
+ +

◆ lzma_stream_buffer_bound()

+ +
+
+ + + + + + + + +
size_t lzma_stream_buffer_bound (size_t uncompressed_size)
+
+ +

Calculate output buffer size for single-call Stream encoder.

+

When trying to compress incompressible data, the encoded size will be slightly bigger than the input data. This function calculates how much output buffer space is required to be sure that lzma_stream_buffer_encode() doesn't return LZMA_BUF_ERROR.

+

The calculated value is not exact, but it is guaranteed to be big enough. The actual maximum output space required may be slightly smaller (up to about 100 bytes). This should not be a problem in practice.

+

If the calculated maximum size doesn't fit into size_t or would make the Stream grow past LZMA_VLI_MAX (which should never happen in practice), zero is returned to indicate the error.

+
Note
The limit calculated by this function applies only to single-call encoding. Multi-call encoding may (and probably will) have larger maximum expansion when encoding incompressible data. Currently there is no function to calculate the maximum expansion of multi-call encoding.
+
Parameters
+ + +
uncompressed_sizeSize in bytes of the uncompressed input data
+
+
+
Returns
Maximum number of bytes needed to store the compressed data.
+ +

◆ lzma_microlzma_encoder()

+ +
+
+ + + + + + + + + + + + + + + + + + +
lzma_ret lzma_microlzma_encoder (lzma_stream * strm,
const lzma_options_lzma * options 
)
+
+ +

MicroLZMA encoder.

+

The MicroLZMA format is a raw LZMA stream whose first byte (always 0x00) has been replaced with bitwise-negation of the LZMA properties (lc/lp/pb). This encoding ensures that the first byte of MicroLZMA stream is never 0x00. There is no end of payload marker and thus the uncompressed size must be stored separately. For the best error detection the dictionary size should be stored separately as well but alternatively one may use the uncompressed size as the dictionary size when decoding.

+

With the MicroLZMA encoder, lzma_code() behaves slightly unusually. The action argument must be LZMA_FINISH and the return value will never be LZMA_OK. Thus the encoding is always done with a single lzma_code() after the initialization. The benefit of the combination of initialization function and lzma_code() is that memory allocations can be re-used for better performance.

+

lzma_code() will try to encode as much input as is possible to fit into the given output buffer. If not all input can be encoded, the stream will be finished without encoding all the input. The caller must check both input and output buffer usage after lzma_code() (total_in and total_out in lzma_stream can be convenient). Often lzma_code() can fill the output buffer completely if there is a lot of input, but sometimes a few bytes may remain unused because the next LZMA symbol would require more space.

+

lzma_stream.avail_out must be at least 6. Otherwise LZMA_PROG_ERROR will be returned.

+

The LZMA dictionary should be reasonably low to speed up the encoder re-initialization. A good value is bigger than the resulting uncompressed size of most of the output chunks. For example, if output size is 4 KiB, dictionary size of 32 KiB or 64 KiB is good. If the data compresses extremely well, even 128 KiB may be useful.

+

The MicroLZMA format and this encoder variant were made with the EROFS file system in mind. This format may be convenient in other embedded uses too where many small streams are needed. XZ Embedded includes a decoder for this format.

+
Parameters
+ + + +
strmPointer to lzma_stream that is at least initialized with LZMA_STREAM_INIT.
optionsPointer to encoder options
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_STREAM_END: All good. Check the amounts of input used and output produced. Store the amount of input used (uncompressed size) as it needs to be known to decompress the data.
    • +
  • LZMA_OPTIONS_ERROR
    • +
  • LZMA_MEM_ERROR
    • +
  • LZMA_PROG_ERROR: In addition to the generic reasons for this error code, this may also be returned if there isn't enough output space (6 bytes) to create a valid MicroLZMA stream.

◆ lzma_stream_decoder()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + +
lzma_ret lzma_stream_decoder (lzma_stream * strm,
uint64_t memlimit,
uint32_t flags 
)
+
+ +

Initialize .xz Stream decoder.

+
Parameters
+ + + + +
strmPointer to lzma_stream that is at least initialized with LZMA_STREAM_INIT.
memlimitMemory usage limit as bytes. Use UINT64_MAX to effectively disable the limiter. liblzma 5.2.3 and earlier don't allow 0 here and return LZMA_PROG_ERROR; later versions treat 0 as if 1 had been specified.
flagsBitwise-or of zero or more of the decoder flags: LZMA_TELL_NO_CHECK, LZMA_TELL_UNSUPPORTED_CHECK, LZMA_TELL_ANY_CHECK, LZMA_IGNORE_CHECK, LZMA_CONCATENATED, LZMA_FAIL_FAST
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK: Initialization was successful.
    • +
  • LZMA_MEM_ERROR: Cannot allocate memory.
    • +
  • LZMA_OPTIONS_ERROR: Unsupported flags
    • +

◆ lzma_stream_decoder_mt()

+ +
+
+ + + + + + + + + + + + + + + + + + +
lzma_ret lzma_stream_decoder_mt (lzma_stream * strm,
const lzma_mt * options 
)
+
+ +

Initialize multithreaded .xz Stream decoder.

+

The decoder can decode multiple Blocks in parallel. This requires that each Block Header contains the Compressed Size and Uncompressed size fields which are added by the multi-threaded encoder, see lzma_stream_encoder_mt().

+

A Stream with one Block will only utilize one thread. A Stream with multiple Blocks but without size information in Block Headers will be processed in single-threaded mode in the same way as done by lzma_stream_decoder(). Concatenated Streams are processed one Stream at a time; no inter-Stream parallelization is done.

+

This function behaves like lzma_stream_decoder() when options->threads == 1 and options->memlimit_threading <= 1.

+
Parameters
+ + + +
strmPointer to lzma_stream that is at least initialized with LZMA_STREAM_INIT.
optionsPointer to multithreaded compression options
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK: Initialization was successful.
    • +
  • LZMA_MEM_ERROR: Cannot allocate memory.
    • +
  • LZMA_MEMLIMIT_ERROR: Memory usage limit was reached.
    • +
  • LZMA_OPTIONS_ERROR: Unsupported flags.
    • +
  • LZMA_PROG_ERROR

◆ lzma_auto_decoder()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + +
lzma_ret lzma_auto_decoder (lzma_stream * strm,
uint64_t memlimit,
uint32_t flags 
)
+
+ +

Decode .xz, .lzma, and .lz (lzip) files with autodetection.

+

This decoder autodetects between the .xz, .lzma, and .lz file formats, and calls lzma_stream_decoder(), lzma_alone_decoder(), or lzma_lzip_decoder() once the type of the input file has been detected.

+

Support for .lz was added in 5.4.0.

+

If the flag LZMA_CONCATENATED is used and the input is a .lzma file: For historical reasons concatenated .lzma files aren't supported. If there is trailing data after one .lzma stream, lzma_code() will return LZMA_DATA_ERROR. (lzma_alone_decoder() doesn't have such a check as it doesn't support any decoder flags. It will return LZMA_STREAM_END after one .lzma stream.)

+
Parameters
+ + + + +
strmPointer to lzma_stream that is at least initialized with LZMA_STREAM_INIT.
memlimitMemory usage limit as bytes. Use UINT64_MAX to effectively disable the limiter. liblzma 5.2.3 and earlier don't allow 0 here and return LZMA_PROG_ERROR; later versions treat 0 as if 1 had been specified.
flagsBitwise-or of zero or more of the decoder flags: LZMA_TELL_NO_CHECK, LZMA_TELL_UNSUPPORTED_CHECK, LZMA_TELL_ANY_CHECK, LZMA_IGNORE_CHECK, LZMA_CONCATENATED, LZMA_FAIL_FAST
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK: Initialization was successful.
    • +
  • LZMA_MEM_ERROR: Cannot allocate memory.
    • +
  • LZMA_OPTIONS_ERROR: Unsupported flags

+ + + + + + + + + + + + + + + + + + +
lzma_ret lzma_alone_decoder (lzma_stream * strm,
uint64_t memlimit 
)
+
+ +

Initialize .lzma decoder (legacy file format)

+

Valid `action' arguments to lzma_code() are LZMA_RUN and LZMA_FINISH. There is no need to use LZMA_FINISH, but it's allowed because it may simplify certain types of applications.

+
Parameters
+ + + +
strmPointer to lzma_stream that is at least initialized with LZMA_STREAM_INIT.
memlimitMemory usage limit as bytes. Use UINT64_MAX to effectively disable the limiter. liblzma 5.2.3 and earlier don't allow 0 here and return LZMA_PROG_ERROR; later versions treat 0 as if 1 had been specified.
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK
    • +
  • LZMA_MEM_ERROR
    • +
  • LZMA_PROG_ERROR
    • +

◆ lzma_lzip_decoder()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + +
lzma_ret lzma_lzip_decoder (lzma_stream * strm,
uint64_t memlimit,
uint32_t flags 
)
+
+ +

Initialize .lz (lzip) decoder (a foreign file format)

+

This decoder supports the .lz format version 0 and the unextended .lz format version 1:

+
    +
  • Files in the format version 0 were produced by lzip 1.3 and older. Such files aren't common but may be found from file archives as a few source packages were released in this format. People might have old personal files in this format too. Decompression support for the format version 0 was removed in lzip 1.18.
    • +
  • lzip 1.3 added decompression support for .lz format version 1 files. Compression support was added in lzip 1.4. In lzip 1.6 the .lz format version 1 was extended to support the Sync Flush marker. This extension is not supported by liblzma. lzma_code() will return LZMA_DATA_ERROR at the location of the Sync Flush marker. In practice files with the Sync Flush marker are very rare and thus liblzma can decompress almost all .lz files.
    • +
+

Just like with lzma_stream_decoder() for .xz files, LZMA_CONCATENATED should be used when decompressing normal standalone .lz files.

The .lz format allows putting non-.lz data at the end of a file after at least one valid .lz member. That is, one can append custom data at the end of a .lz file and the decoder is required to ignore it. In liblzma this is relevant only when LZMA_CONCATENATED is used. In that case lzma_code() will return LZMA_STREAM_END and leave lzma_stream.next_in pointing to the first byte of the non-.lz data. An exception to this is if the first 1-3 bytes of the non-.lz data are identical to the .lz magic bytes (0x4C, 0x5A, 0x49, 0x50; "LZIP" in US-ASCII). In such a case the 1-3 bytes will have been ignored by lzma_code(). If one wishes to locate the non-.lz data reliably, one must ensure that the first byte isn't 0x4C. Actually one should ensure that none of the first four bytes of trailing data are equal to the magic bytes because lzip >= 1.20 requires it by default.

+
Parameters
+ + + + +
strmPointer to lzma_stream that is at least initialized with LZMA_STREAM_INIT.
memlimitMemory usage limit as bytes. Use UINT64_MAX to effectively disable the limiter.
flagsBitwise-or of flags, or zero for no flags. All decoder flags listed above are supported although only LZMA_CONCATENATED and (in very rare cases) LZMA_IGNORE_CHECK are actually useful. LZMA_TELL_NO_CHECK, LZMA_TELL_UNSUPPORTED_CHECK, and LZMA_FAIL_FAST do nothing. LZMA_TELL_ANY_CHECK is supported for consistency only as CRC32 is always used in the .lz format.
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK: Initialization was successful.
    • +
  • LZMA_MEM_ERROR: Cannot allocate memory.
    • +
  • LZMA_OPTIONS_ERROR: Unsupported flags
    • +
  • LZMA_PROG_ERROR

Single-call .xz Stream decoder.

+
Parameters
+ + + + + + + + + + +
memlimitPointer to how much memory the decoder is allowed to allocate. The value pointed by this pointer is modified if and only if LZMA_MEMLIMIT_ERROR is returned.
flagsBitwise-or of zero or more of the decoder flags: LZMA_TELL_NO_CHECK, LZMA_TELL_UNSUPPORTED_CHECK, LZMA_IGNORE_CHECK, LZMA_CONCATENATED, LZMA_FAIL_FAST. Note that LZMA_TELL_ANY_CHECK is not allowed and will return LZMA_PROG_ERROR.
allocatorlzma_allocator for custom allocator functions. Set to NULL to use malloc() and free().
inBeginning of the input buffer
in_posThe next byte will be read from in[*in_pos]. *in_pos is updated only if decoding succeeds.
in_sizeSize of the input buffer; the first byte that won't be read is in[in_size].
[out]outBeginning of the output buffer
[out]out_posThe next byte will be written to out[*out_pos]. *out_pos is updated only if decoding succeeds.
out_sizeSize of the out buffer; the first byte into which no data is written to is out[out_size].
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK: Decoding was successful.
    • +
  • LZMA_FORMAT_ERROR
    • +
  • LZMA_OPTIONS_ERROR
    • +
  • LZMA_DATA_ERROR
    • +
  • LZMA_NO_CHECK: This can be returned only if using the LZMA_TELL_NO_CHECK flag.
    • +
  • LZMA_UNSUPPORTED_CHECK: This can be returned only if using the LZMA_TELL_UNSUPPORTED_CHECK flag.
    • +
  • LZMA_MEM_ERROR
    • +
  • LZMA_MEMLIMIT_ERROR: Memory usage limit was reached. The minimum required memlimit value was stored to *memlimit.
    • +
  • LZMA_BUF_ERROR: Output buffer was too small.
    • +
  • LZMA_PROG_ERROR

◆ lzma_microlzma_decoder()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
lzma_ret lzma_microlzma_decoder (lzma_stream * strm,
uint64_t comp_size,
uint64_t uncomp_size,
lzma_bool uncomp_size_is_exact,
uint32_t dict_size 
)
+
+ +

MicroLZMA decoder.

+

See lzma_microlzma_encoder() for more information.

+

The lzma_code() usage with this decoder is completely normal. The special behavior of lzma_code() applies to lzma_microlzma_encoder() only.

+
Parameters
+ + + + + + +
strmPointer to lzma_stream that is at least initialized with LZMA_STREAM_INIT.
comp_sizeCompressed size of the MicroLZMA stream. The caller must somehow know this exactly.
uncomp_sizeUncompressed size of the MicroLZMA stream. If the exact uncompressed size isn't known, this can be set to a value that is at most as big as the exact uncompressed size would be, but then the next argument uncomp_size_is_exact must be false.
uncomp_size_is_exactIf true, uncomp_size must be exactly correct. This will improve error detection at the end of the stream. If the exact uncompressed size isn't known, this must be false. uncomp_size must still be at most as big as the exact uncompressed size is. Setting this to false when the exact size is known will work but error detection at the end of the stream will be weaker.
dict_sizeLZMA dictionary size that was used when compressing the data. It is OK to use a bigger value too but liblzma will then allocate more memory than would actually be required and error detection will be slightly worse. (Note that with the implementation in XZ Embedded it doesn't affect the memory usage if one specifies bigger dictionary than actually required.)

Type of the delta calculation.

+

Currently only byte-wise delta is supported. Other possible types could be, for example, delta of 16/32/64-bit little/big endian integers, but these are not currently planned since byte-wise delta is almost as good.

Common filter related types and functions.

Note
Never include this file directly. Use <lzma.h> instead.
+

Macro Definition Documentation

+ +

◆ LZMA_FILTERS_MAX

+ +
+
+ + + + +
#define LZMA_FILTERS_MAX   4
+
+ +

Maximum number of filters in a chain.

+

A filter chain can have 1-4 filters, of which three are allowed to change the size of the data. Usually only one or two filters are needed.

+ +
+
+ +

◆ LZMA_STR_ALL_FILTERS

+ +
+
+ + + + +
#define LZMA_STR_ALL_FILTERS   UINT32_C(0x01)
+
+ +

Allow or show all filters.

+

By default only the filters supported in the .xz format are accept by lzma_str_to_filters() or shown by lzma_str_list_filters().

+ +
+
+ +

◆ LZMA_STR_NO_VALIDATION

+ +
+
+ + + + +
#define LZMA_STR_NO_VALIDATION   UINT32_C(0x02)
+
+ +

Do not validate the filter chain in lzma_str_to_filters()

+

By default lzma_str_to_filters() can return an error if the filter chain as a whole isn't usable in the .xz format or in the raw encoder or decoder. With this flag, this validation is skipped. This flag doesn't affect the handling of the individual filter options. To allow non-.xz filters also LZMA_STR_ALL_FILTERS is needed.

+ +
+
+ +

◆ LZMA_STR_ENCODER

+ +
+
+ + + + +
#define LZMA_STR_ENCODER   UINT32_C(0x10)
+
+ +

Stringify encoder options.

+

Show the filter-specific options that the encoder will use. This may be useful for verbose diagnostic messages.

+

Note that if options were decoded from .xz headers then the encoder options may be undefined. This flag shouldn't be used in such a situation.

+ +
+
+ +

◆ LZMA_STR_DECODER

+ +
+
+ + + + +
#define LZMA_STR_DECODER   UINT32_C(0x20)
+
+ +

Stringify decoder options.

+

Show the filter-specific options that the decoder will use. This may be useful for showing what filter options were decoded from file headers.

+ +
+
+ +

◆ LZMA_STR_GETOPT_LONG

+ +
+
+ + + + +
#define LZMA_STR_GETOPT_LONG   UINT32_C(0x40)
+
+ +

Produce xz-compatible getopt_long() syntax.

+

That is, "delta:dist=2 lzma2:dict=4MiB,pb=1,lp=1" becomes "--delta=dist=2 --lzma2=dict=4MiB,pb=1,lp=1".

+

This syntax is compatible with xz 5.0.0 as long as the filters and their options are supported too.

+ +
+
+ +

◆ LZMA_STR_NO_SPACES

+ +
+
+ + + + +
#define LZMA_STR_NO_SPACES   UINT32_C(0x80)
+
+ +

Use two dashes "--" instead of a space to separate filters.

+

That is, "delta:dist=2 lzma2:pb=1,lp=1" becomes "delta:dist=2--lzma2:pb=1,lp=1". This looks slightly odd but this kind of strings should be usable on the command line without quoting. However, it is possible that future versions with new filter options might produce strings that require shell quoting anyway as the exact set of possible characters isn't frozen for now.

+

It is guaranteed that the single quote (') will never be used in filter chain strings (even if LZMA_STR_NO_SPACES isn't used).

◆ lzma_filter_encoder_is_supported()

+ +
+
+ + + + + + + + +
lzma_bool lzma_filter_encoder_is_supported (lzma_vli id) const
+
+ +

Test if the given Filter ID is supported for encoding.

+
Parameters
+ + +
idFilter ID
+
+
+
Returns
lzma_bool:
    +
  • true if the Filter ID is supported for encoding by this liblzma build.
    • +
  • false otherwise.
    • +
+
+ +
+
+ +

◆ lzma_filter_decoder_is_supported()

+ +
+
+ + + + + + + + +
lzma_bool lzma_filter_decoder_is_supported (lzma_vli id) const
+
+ +

Test if the given Filter ID is supported for decoding.

+
Parameters
+ + +
idFilter ID
+
+
+
Returns
lzma_bool:
    +
  • true if the Filter ID is supported for decoding by this liblzma build.
    • +
  • false otherwise.
    • +
+
+ +
+
+ +

◆ lzma_filters_copy()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + +
lzma_ret lzma_filters_copy (const lzma_filter * src,
lzma_filter * dest,
const lzma_allocator * allocator 
)
+
+ +

Copy the filters array.

+

Copy the Filter IDs and filter-specific options from src to dest. Up to LZMA_FILTERS_MAX filters are copied, plus the terminating .id == LZMA_VLI_UNKNOWN. Thus, dest should have at least LZMA_FILTERS_MAX + 1 elements space unless the caller knows that src is smaller than that.

+

Unless the filter-specific options is NULL, the Filter ID has to be supported by liblzma, because liblzma needs to know the size of every filter-specific options structure. The filter-specific options are not validated. If options is NULL, any unsupported Filter IDs are copied without returning an error.

+

Old filter-specific options in dest are not freed, so dest doesn't need to be initialized by the caller in any way.

+

If an error occurs, memory possibly already allocated by this function is always freed. liblzma versions older than 5.2.7 may modify the dest array and leave its contents in an undefined state if an error occurs. liblzma 5.2.7 and newer only modify the dest array when returning LZMA_OK.

+
Parameters
+ + + + +
srcArray of filters terminated with .id == LZMA_VLI_UNKNOWN.
[out]destDestination filter array
allocatorlzma_allocator for custom allocator functions. Set to NULL to use malloc() and free().
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK
    • +
  • LZMA_MEM_ERROR
    • +
  • LZMA_OPTIONS_ERROR: Unsupported Filter ID and its options is not NULL.
    • +
  • LZMA_PROG_ERROR: src or dest is NULL.
    • +
+
+ +
+
+ +

◆ lzma_filters_free()

+ +
+
+ + + + + + + + + + + + + + + + + + +
void lzma_filters_free (lzma_filter * filters,
const lzma_allocator * allocator 
)
+
+ +

Free the options in the array of lzma_filter structures.

+

This frees the filter chain options. The filters array itself is not freed.

+

The filters array must have at most LZMA_FILTERS_MAX + 1 elements including the terminating element which must have .id = LZMA_VLI_UNKNOWN. For all elements before the terminating element:

    +
  • options will be freed using the given lzma_allocator or, if allocator is NULL, using free().
    • +
  • options will be set to NULL.
    • +
  • id will be set to LZMA_VLI_UNKNOWN.
    • +
+

If filters is NULL, this does nothing. Again, this never frees the filters array itself.

+
Parameters
+ + + +
filtersArray of filters terminated with .id == LZMA_VLI_UNKNOWN.
allocatorlzma_allocator for custom allocator functions. Set to NULL to use malloc() and free().
+
+
+ +
+
+ +

◆ lzma_raw_encoder_memusage()

+ +
+
+ + + + + + + + +
uint64_t lzma_raw_encoder_memusage (const lzma_filter * filters)
+
+ +

Calculate approximate memory requirements for raw encoder.

+

This function can be used to calculate the memory requirements for Block and Stream encoders too because Block and Stream encoders don't need significantly more memory than raw encoder.

+
Parameters
+ + +
filtersArray of filters terminated with .id == LZMA_VLI_UNKNOWN.
+
+
+
Returns
Number of bytes of memory required for the given filter chain when encoding or UINT64_MAX on error.
+ +
+
+ +

◆ lzma_raw_decoder_memusage()

+ +
+
+ + + + + + + + +
uint64_t lzma_raw_decoder_memusage (const lzma_filter * filters)
+
+ +

Calculate approximate memory requirements for raw decoder.

+

This function can be used to calculate the memory requirements for Block and Stream decoders too because Block and Stream decoders don't need significantly more memory than raw decoder.

+
Parameters
+ + +
filtersArray of filters terminated with .id == LZMA_VLI_UNKNOWN.
+
+
+
Returns
Number of bytes of memory required for the given filter chain when decoding or UINT64_MAX on error.
+ +
+
+ +

◆ lzma_raw_encoder()

+ +
+
+ + + + + + + + + + + + + + + + + + +
lzma_ret lzma_raw_encoder (lzma_stream * strm,
const lzma_filter * filters 
)
+
+ +

Initialize raw encoder.

+

This function may be useful when implementing custom file formats.

+

The `action' with lzma_code() can be LZMA_RUN, LZMA_SYNC_FLUSH (if the filter chain supports it), or LZMA_FINISH.

+
Parameters
+ + + +
strmPointer to lzma_stream that is at least initialized with LZMA_STREAM_INIT.
filtersArray of filters terminated with .id == LZMA_VLI_UNKNOWN.
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK
    • +
  • LZMA_MEM_ERROR
    • +
  • LZMA_OPTIONS_ERROR
    • +
  • LZMA_PROG_ERROR
    • +
+
+ +
+
+ +

◆ lzma_raw_decoder()

+ +
+
+ + + + + + + + + + + + + + + + + + +
lzma_ret lzma_raw_decoder (lzma_stream * strm,
const lzma_filter * filters 
)
+
+ +

Initialize raw decoder.

+

The initialization of raw decoder goes similarly to raw encoder.

+

The `action' with lzma_code() can be LZMA_RUN or LZMA_FINISH. Using LZMA_FINISH is not required, it is supported just for convenience.

+
Parameters
+ + + +
strmPointer to lzma_stream that is at least initialized with LZMA_STREAM_INIT.
filtersArray of filters terminated with .id == LZMA_VLI_UNKNOWN.
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK
    • +
  • LZMA_MEM_ERROR
    • +
  • LZMA_OPTIONS_ERROR
    • +
  • LZMA_PROG_ERROR
    • +
+
+ +
+
+ +

◆ lzma_filters_update()

+ +
+
+ + + + + + + + + + + + + + + + + + +
lzma_ret lzma_filters_update (lzma_stream * strm,
const lzma_filter * filters 
)
+
+ +

Update the filter chain in the encoder.

+

This function may be called after lzma_code() has returned LZMA_STREAM_END when LZMA_FULL_BARRIER, LZMA_FULL_FLUSH, or LZMA_SYNC_FLUSH was used:

+
    +
  • After LZMA_FULL_BARRIER or LZMA_FULL_FLUSH: Single-threaded .xz Stream encoder (lzma_stream_encoder()) and (since liblzma 5.4.0) multi-threaded Stream encoder (lzma_stream_encoder_mt()) allow setting a new filter chain to be used for the next Block(s).
    • +
  • After LZMA_SYNC_FLUSH: Raw encoder (lzma_raw_encoder()), Block encoder (lzma_block_encoder()), and single-threaded .xz Stream encoder (lzma_stream_encoder()) allow changing certain filter-specific options in the middle of encoding. The actual filters in the chain (Filter IDs) must not be changed! Currently only the lc, lp, and pb options of LZMA2 (not LZMA1) can be changed this way.
    • +
  • In the future some filters might allow changing some of their options without any barrier or flushing but currently such filters don't exist.
    • +
+

This function may also be called when no data has been compressed yet although this is rarely useful. In that case, this function will behave as if LZMA_FULL_FLUSH (Stream encoders) or LZMA_SYNC_FLUSH (Raw or Block encoder) had been used right before calling this function.

+
Parameters
+ + + +
strmPointer to lzma_stream that is at least initialized with LZMA_STREAM_INIT.
filtersArray of filters terminated with .id == LZMA_VLI_UNKNOWN.
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK
    • +
  • LZMA_MEM_ERROR
    • +
  • LZMA_MEMLIMIT_ERROR
    • +
  • LZMA_OPTIONS_ERROR
    • +
  • LZMA_PROG_ERROR
    • +
+
+ +
+
+ +

◆ lzma_raw_buffer_encode()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
lzma_ret lzma_raw_buffer_encode (const lzma_filter * filters,
const lzma_allocator * allocator,
const uint8_t * in,
size_t in_size,
uint8_t * out,
size_t * out_pos,
size_t out_size 
)
+
+ +

Single-call raw encoder.

+
Note
There is no function to calculate how big output buffer would surely be big enough. (lzma_stream_buffer_bound() works only for lzma_stream_buffer_encode(); raw encoder won't necessarily meet that bound.)
+
Parameters
+ + + + + + + + +
filtersArray of filters terminated with .id == LZMA_VLI_UNKNOWN.
allocatorlzma_allocator for custom allocator functions. Set to NULL to use malloc() and free().
inBeginning of the input buffer
in_sizeSize of the input buffer
[out]outBeginning of the output buffer
[out]out_posThe next byte will be written to out[*out_pos]. *out_pos is updated only if encoding succeeds.
out_sizeSize of the out buffer; the first byte into which no data is written to is out[out_size].
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK: Encoding was successful.
    • +
  • LZMA_BUF_ERROR: Not enough output buffer space.
    • +
  • LZMA_OPTIONS_ERROR
    • +
  • LZMA_MEM_ERROR

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

Single-call raw decoder.

+
Parameters
+ + + + + + + + + +
filtersArray of filters terminated with .id == LZMA_VLI_UNKNOWN.
allocatorlzma_allocator for custom allocator functions. Set to NULL to use malloc() and free().
inBeginning of the input buffer
in_posThe next byte will be read from in[*in_pos]. *in_pos is updated only if decoding succeeds.
in_sizeSize of the input buffer; the first byte that won't be read is in[in_size].
[out]outBeginning of the output buffer
[out]out_posThe next byte will be written to out[*out_pos]. *out_pos is updated only if encoding succeeds.
out_sizeSize of the out buffer; the first byte into which no data is written to is out[out_size].

◆ lzma_properties_size()

+ +
+
+ + + + + + + + + + + + + + + + + + +
lzma_ret lzma_properties_size (uint32_t * size,
const lzma_filter * filter 
)
+
+ +

Get the size of the Filter Properties field.

+

This function may be useful when implementing custom file formats using the raw encoder and decoder.

+
Note
This function validates the Filter ID, but does not necessarily validate the options. Thus, it is possible that this returns LZMA_OK while the following call to lzma_properties_encode() returns LZMA_OPTIONS_ERROR.
+
Parameters
+ + + +
[out]sizePointer to uint32_t to hold the size of the properties
filterFilter ID and options (the size of the properties may vary depending on the options)
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK
    • +
  • LZMA_OPTIONS_ERROR
    • +
  • LZMA_PROG_ERROR
    • +
+
+ +
+
+ +

◆ lzma_properties_encode()

+ +
+
+ + + + + + + + + + + + + + + + + + +
lzma_ret lzma_properties_encode (const lzma_filter * filter,
uint8_t * props 
)
+
+ +

Encode the Filter Properties field.

+
Note
Even this function won't validate more options than actually necessary. Thus, it is possible that encoding the properties succeeds but using the same options to initialize the encoder will fail.
+
+If lzma_properties_size() indicated that the size of the Filter Properties field is zero, calling lzma_properties_encode() is not required, but it won't do any harm either.
+
Parameters
+ + + +
filterFilter ID and options
[out]propsBuffer to hold the encoded options. The size of the buffer must have been already determined with lzma_properties_size().
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK
    • +
  • LZMA_PROG_ERROR
    • +
+
+ +
+
+ +

◆ lzma_properties_decode()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
lzma_ret lzma_properties_decode (lzma_filter * filter,
const lzma_allocator * allocator,
const uint8_t * props,
size_t props_size 
)
+
+ +

Decode the Filter Properties field.

+
Parameters
+ + + + + +
filterfilter->id must have been set to the correct Filter ID. filter->options doesn't need to be initialized (it's not freed by this function). The decoded options will be stored in filter->options; it's application's responsibility to free it when appropriate. filter->options is set to NULL if there are no properties or if an error occurs.
allocatorlzma_allocator for custom allocator functions. Set to NULL to use malloc() and free(). and in case of an error, also free().
propsInput buffer containing the properties.
props_sizeSize of the properties. This must be the exact size; giving too much or too little input will return LZMA_OPTIONS_ERROR.
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK
    • +
  • LZMA_OPTIONS_ERROR
    • +
  • LZMA_MEM_ERROR
    • +
+
+ +
+
+ +

◆ lzma_filter_flags_size()

+ +
+
+ + + + + + + + + + + + + + + + + + +
lzma_ret lzma_filter_flags_size (uint32_t * size,
const lzma_filter * filter 
)
+
+ +

Calculate encoded size of a Filter Flags field.

+

Knowing the size of Filter Flags is useful to know when allocating memory to hold the encoded Filter Flags.

+
Note
If you need to calculate size of List of Filter Flags, you need to loop over every lzma_filter entry.
+
Parameters
+ + + +
[out]sizePointer to integer to hold the calculated size
filterFilter ID and associated options whose encoded size is to be calculated
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK: *size set successfully. Note that this doesn't guarantee that filter->options is valid, thus lzma_filter_flags_encode() may still fail.
    • +
  • LZMA_OPTIONS_ERROR: Unknown Filter ID or unsupported options.
    • +
  • LZMA_PROG_ERROR: Invalid options
    • +
+
+ +
+
+ +

◆ lzma_filter_flags_encode()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
lzma_ret lzma_filter_flags_encode (const lzma_filter * filter,
uint8_t * out,
size_t * out_pos,
size_t out_size 
)
+
+ +

Encode Filter Flags into given buffer.

+

In contrast to some functions, this doesn't allocate the needed buffer. This is due to how this function is used internally by liblzma.

+
Parameters
+ + + + + +
filterFilter ID and options to be encoded
[out]outBeginning of the output buffer
[out]out_posout[*out_pos] is the next write position. This is updated by the encoder.
out_sizeout[out_size] is the first byte to not write.
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK: Encoding was successful.
    • +
  • LZMA_OPTIONS_ERROR: Invalid or unsupported options.
    • +
  • LZMA_PROG_ERROR: Invalid options or not enough output buffer space (you should have checked it with lzma_filter_flags_size()).
    • +
+
+ +
+
+ +

◆ lzma_filter_flags_decode()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
lzma_ret lzma_filter_flags_decode (lzma_filter * filter,
const lzma_allocator * allocator,
const uint8_t * in,
size_t * in_pos,
size_t in_size 
)
+
+ +

Decode Filter Flags from given buffer.

+

The decoded result is stored into *filter. The old value of filter->options is not free()d. If anything other than LZMA_OK is returned, filter->options is set to NULL.

+
Parameters
+ + + + + + +
[out]filterDestination filter. The decoded Filter ID will be stored in filter->id. If options are needed they will be allocated and the pointer will be stored in filter->options.
allocatorlzma_allocator for custom allocator functions. Set to NULL to use malloc() and free().
inBeginning of the input buffer
[out]in_posThe next byte will be read from in[*in_pos]. *in_pos is updated only if decoding succeeds.
in_sizeSize of the input buffer; the first byte that won't be read is in[in_size].
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK
    • +
  • LZMA_OPTIONS_ERROR
    • +
  • LZMA_MEM_ERROR
    • +
  • LZMA_DATA_ERROR

◆ lzma_str_to_filters()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
const char * lzma_str_to_filters (const char * str,
int * error_pos,
lzma_filter * filters,
uint32_t flags,
const lzma_allocator * allocator 
)
+
+ +

Convert a string to a filter chain.

+

This tries to make it easier to write applications that allow users to set custom compression options. This only handles the filter configuration (including presets) but not the number of threads, block size, check type, or memory limits.

+

The input string can be either a preset or a filter chain. Presets begin with a digit 0-9 and may be followed by zero or more flags which are lower-case letters. Currently only "e" is supported, matching LZMA_PRESET_EXTREME. For partial xz command line syntax compatibility, a preset string may start with a single dash "-".

+

A filter chain consists of one or more "filtername:opt1=value1,opt2=value2" strings separated by one or more spaces. Leading and trailing spaces are ignored. All names and values must be lower-case. Extra commas in the option list are ignored. The order of filters is significant: when encoding, the uncompressed input data goes to the leftmost filter first. Normally "lzma2" is the last filter in the chain.

+

If one wishes to avoid spaces, for example, to avoid shell quoting, it is possible to use two dashes "--" instead of spaces to separate the filters.

+

For xz command line compatibility, each filter may be prefixed with two dashes "--" and the colon ":" separating the filter name from the options may be replaced with an equals sign "=".

+

By default, only filters that can be used in the .xz format are accepted. To allow all filters (LZMA1) use the flag LZMA_STR_ALL_FILTERS.

+

By default, very basic validation is done for the filter chain as a whole, for example, that LZMA2 is only used as the last filter in the chain. The validation isn't perfect though and it's possible that this function succeeds but using the filter chain for encoding or decoding will still result in LZMA_OPTIONS_ERROR. To disable this validation, use the flag LZMA_STR_NO_VALIDATION.

+

The available filter names and their options are available via lzma_str_list_filters(). See the xz man page for the description of filter names and options.

+

For command line applications, below is an example how an error message can be displayed. Note the use of an empty string for the field width. If "^" was used there it would create an off-by-one error except at the very beginning of the line.

+
const char *str = ...; // From user
+
lzma_filter filters[LZMA_FILTERS_MAX + 1];
+
int pos;
+
const char *msg = lzma_str_to_filters(str, &pos, filters, 0, NULL);
+
if (msg != NULL) {
+
printf("%s: Error in XZ compression options:\n", argv[0]);
+
printf("%s: %s\n", argv[0], str);
+
printf("%s: %*s^\n", argv[0], errpos, "");
+
printf("%s: %s\n", argv[0], msg);
+
}
+
Parameters
+ + + + + + +
strUser-supplied string describing a preset or a filter chain. If a default value is needed and you don't know what would be good, use "6" since that is the default preset in xz too.
[out]error_posIf this isn't NULL, this value will be set on both success and on all errors. This tells the location of the error in the string. This is an int to make it straightforward to use this as printf() field width. The value is guaranteed to be in the range [0, INT_MAX] even if strlen(str) somehow was greater than INT_MAX.
[out]filtersAn array of lzma_filter structures. There must be LZMA_FILTERS_MAX + 1 (that is, five) elements in the array. The old contents are ignored so it doesn't need to be initialized. This array is modified only if this function returns NULL. Once the allocated filter options are no longer needed, lzma_filters_free() can be used to free the options (it doesn't free the filters array itself).
flagsBitwise-or of zero or more of the flags LZMA_STR_ALL_FILTERS and LZMA_STR_NO_VALIDATION.
allocatorlzma_allocator for custom allocator functions. Set to NULL to use malloc() and free().
+
+
+
Returns
On success, NULL is returned. On error, a statically-allocated error message is returned which together with the error_pos should give some idea what is wrong.
+ +
+
+ +

◆ lzma_str_from_filters()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
lzma_ret lzma_str_from_filters (char ** str,
const lzma_filter * filters,
uint32_t flags,
const lzma_allocator * allocator 
)
+
+ +

Convert a filter chain to a string.

+

Use cases:

+
    +
  • Verbose output showing the full encoder options to the user (use LZMA_STR_ENCODER in flags)
    • +
  • Showing the filters and options that are required to decode a file (use LZMA_STR_DECODER in flags)
    • +
  • Showing the filter names without any options in informational messages where the technical details aren't important (no flags). In this case the .options in the filters array are ignored and may be NULL even if a filter has a mandatory options structure.
    • +
+

Note that even if the filter chain was specified using a preset, the resulting filter chain isn't reversed to a preset. So if you specify "6" to lzma_str_to_filters() then lzma_str_from_filters() will produce a string containing "lzma2".

+
Parameters
+ + + + + +
[out]strOn success *str will be set to point to an allocated string describing the given filter chain. Old value is ignored. On error *str is always set to NULL.
filtersArray of filters terminated with .id == LZMA_VLI_UNKNOWN.
flagsBitwise-or of zero or more of the flags LZMA_STR_ENCODER, LZMA_STR_DECODER, LZMA_STR_GETOPT_LONG, and LZMA_STR_NO_SPACES.
allocatorlzma_allocator for custom allocator functions. Set to NULL to use malloc() and free().
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK
    • +
  • LZMA_OPTIONS_ERROR: Empty filter chain (filters[0].id == LZMA_VLI_UNKNOWN) or the filter chain includes a Filter ID that is not supported by this function.
    • +
  • LZMA_MEM_ERROR
    • +
  • LZMA_PROG_ERROR

lzma_vli filter_id,
uint32_t flags,
const lzma_allocator * allocator 
)
+
+ +

List available filters and/or their options (for help message)

+

If a filter_id is given then only one line is created which contains the filter name. If LZMA_STR_ENCODER or LZMA_STR_DECODER is used then the options read by the encoder or decoder are printed on the same line.

+

If filter_id is LZMA_VLI_UNKNOWN then all supported .xz-compatible filters are listed:

+
    +
  • If neither LZMA_STR_ENCODER nor LZMA_STR_DECODER is used then the supported filter names are listed on a single line separated by spaces.
    • +
  • If LZMA_STR_ENCODER or LZMA_STR_DECODER is used then filters and the supported options are listed one filter per line. There won't be a newline after the last filter.
    • +
  • If LZMA_STR_ALL_FILTERS is used then the list will include also those filters that cannot be used in the .xz format (LZMA1).
    • +
+
Parameters
+ + + + + +
strOn success *str will be set to point to an allocated string listing the filters and options. Old value is ignored. On error *str is always set to NULL.
filter_idFilter ID or LZMA_VLI_UNKNOWN.
flagsBitwise-or of zero or more of the flags LZMA_STR_ALL_FILTERS, LZMA_STR_ENCODER, LZMA_STR_DECODER, and LZMA_STR_GETOPT_LONG.
allocatorlzma_allocator for custom allocator functions. Set to NULL to use malloc() and free().
+
+

Detailed Description

+

Hardware information.

+
Note
Never include this file directly. Use <lzma.h> instead.
+

Since liblzma can consume a lot of system resources, it also provides ways to limit the resource usage. Applications linking against liblzma need to do the actual decisions how much resources to let liblzma to use. To ease making these decisions, liblzma provides functions to find out the relevant capabilities of the underlying hardware. Currently there is only a function to find out the amount of RAM, but in the future there will be also a function to detect how many concurrent threads the system can run.

+
Note
On some operating systems, these function may temporarily load a shared library or open file descriptor(s) to find out the requested hardware information. Unless the application assumes that specific file descriptors are not touched by other threads, this should have no effect on thread safety. Possible operations involving file descriptors will restart the syscalls if they return EINTR.

◆ lzma_physmem()

+ +
+
+ + + + + + + + +
uint64_t lzma_physmem (void )
+
+ +

Get the total amount of physical memory (RAM) in bytes.

+

This function may be useful when determining a reasonable memory usage limit for decompressing or how much memory it is OK to use for compressing.

+
Returns
On success, the total amount of physical memory in bytes is returned. If the amount of RAM cannot be determined, zero is returned. This can happen if an error occurs or if there is no code in liblzma to detect the amount of RAM on the specific operating system.
+ +
+
+ +

◆ lzma_cputhreads()

+ +
+
+ + + + + + + + +
uint32_t lzma_cputhreads (void )
+
+ +

Get the number of processor cores or threads.

+

This function may be useful when determining how many threads to use. If the hardware supports more than one thread per CPU core, the number of hardware threads is returned if that information is available.

+
Returns
On success, the number of available CPU threads or cores is returned. If this information isn't available or an error occurs, zero is returned.

liblzma (XZ Utils)
+
+
+

liblzma is a public domain general-purpose data compression library with a zlib-like API. The native file format is .xz, but also the old .lzma format and raw (no headers) streams are supported. Multiple compression algorithms (filters) are supported. Currently LZMA2 is the primary filter.

+

liblzma is part of XZ Utils https://tukaani.org/xz/. XZ Utils includes a gzip-like command line tool named xz and some other tools. XZ Utils is developed and maintained by Lasse Collin and Jia Tan.

+

Major parts of liblzma are based on Igor Pavlov's public domain LZMA SDK https://7-zip.org/sdk.html.

+

The SHA-256 implementation is based on the public domain code found from 7-Zip https://7-zip.org/, which has a modified version of the public domain SHA-256 code found from Crypto++ https://www.cryptopp.com/. The SHA-256 code in Crypto++ was written by Kevin Springle and Wei Dai.

Detailed Description

Handling of .xz Index and related information.

Typedef Documentation

+ +

◆ lzma_index

+ +
+
+ + + + +
typedef struct lzma_index_s lzma_index
+
+ +

Opaque data type to hold the Index(es) and other information.

+

lzma_index often holds just one .xz Index and possibly the Stream Flags of the same Stream and size of the Stream Padding field. However, multiple lzma_indexes can be concatenated with lzma_index_cat() and then there may be information about multiple Streams in the same lzma_index.

+

Notes about thread safety: Only one thread may modify lzma_index at a time. All functions that take non-const pointer to lzma_index modify it. As long as no thread is modifying the lzma_index, getting information from the same lzma_index can be done from multiple threads at the same time with functions that take a const pointer to lzma_index or use lzma_index_iter. The same iterator must be used only by one thread at a time, of course, but there can be as many iterators for the same lzma_index as needed.

+ +
+
+

Enumeration Type Documentation

+ +

◆ lzma_index_iter_mode

+ +
+
+ + + + +
enum lzma_index_iter_mode
+
+ +

Operation mode for lzma_index_iter_next()

+ + + + + +
Enumerator
LZMA_INDEX_ITER_ANY 

Get the next Block or Stream.

+

Go to the next Block if the current Stream has at least one Block left. Otherwise go to the next Stream even if it has no Blocks. If the Stream has no Blocks (lzma_index_iter.stream.block_count == 0), lzma_index_iter.block will have undefined values.

+
LZMA_INDEX_ITER_STREAM 

Get the next Stream.

+

Go to the next Stream even if the current Stream has unread Blocks left. If the next Stream has at least one Block, the iterator will point to the first Block. If there are no Blocks, lzma_index_iter.block will have undefined values.

+
LZMA_INDEX_ITER_BLOCK 

Get the next Block.

+

Go to the next Block if the current Stream has at least one Block left. If the current Stream has no Blocks left, the next Stream with at least one Block is located and the iterator will be made to point to the first Block of that Stream.

+
LZMA_INDEX_ITER_NONEMPTY_BLOCK 

Get the next non-empty Block.

+

This is like LZMA_INDEX_ITER_BLOCK except that it will skip Blocks whose Uncompressed Size is zero.

+
+ +
+
+

Function Documentation

+ +

◆ lzma_index_memusage()

+ +
+
+ + + + + + + + + + + + + + + + + + +
uint64_t lzma_index_memusage (lzma_vli streams,
lzma_vli blocks 
)
+
+ +

Calculate memory usage of lzma_index.

+

On disk, the size of the Index field depends on both the number of Records stored and the size of the Records (due to variable-length integer encoding). When the Index is kept in lzma_index structure, the memory usage depends only on the number of Records/Blocks stored in the Index(es), and in case of concatenated lzma_indexes, the number of Streams. The size in RAM is almost always significantly bigger than in the encoded form on disk.

+

This function calculates an approximate amount of memory needed to hold the given number of Streams and Blocks in lzma_index structure. This value may vary between CPU architectures and also between liblzma versions if the internal implementation is modified.

+
Parameters
+ + + +
streamsNumber of Streams
blocksNumber of Blocks
+
+
+
Returns
Approximate memory in bytes needed in a lzma_index structure.
+ +
+
+ +

◆ lzma_index_memused()

+ +
+
+ + + + + + + + +
uint64_t lzma_index_memused (const lzma_index * i)
+
+ +

Calculate the memory usage of an existing lzma_index.

+

This is a shorthand for lzma_index_memusage(lzma_index_stream_count(i), lzma_index_block_count(i)).

+
Parameters
+ + +
iPointer to lzma_index structure
+
+
+
Returns
Approximate memory in bytes used by the lzma_index structure.
+ +
+
+ +

◆ lzma_index_init()

+ +
+
+ + + + + + + + +
lzma_index * lzma_index_init (const lzma_allocator * allocator)
+
+ +

Allocate and initialize a new lzma_index structure.

+
Parameters
+ + +
allocatorlzma_allocator for custom allocator functions. Set to NULL to use malloc() and free().
+
+
+
Returns
On success, a pointer to an empty initialized lzma_index is returned. If allocation fails, NULL is returned.
+ +
+
+ +

◆ lzma_index_end()

+ +
+
+ + + + + + + + + + + + + + + + + + +
void lzma_index_end (lzma_index * i,
const lzma_allocator * allocator 
)
+
+ +

Deallocate lzma_index.

+

If i is NULL, this does nothing.

+
Parameters
+ + + +
iPointer to lzma_index structure to deallocate
allocatorlzma_allocator for custom allocator functions. Set to NULL to use malloc() and free().
+
+
+ +
+
+ +

◆ lzma_index_append()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
lzma_ret lzma_index_append (lzma_index * i,
const lzma_allocator * allocator,
lzma_vli unpadded_size,
lzma_vli uncompressed_size 
)
+
+ +

Add a new Block to lzma_index.

+
Parameters
+ + + + + +
iPointer to a lzma_index structure
allocatorlzma_allocator for custom allocator functions. Set to NULL to use malloc() and free().
unpadded_sizeUnpadded Size of a Block. This can be calculated with lzma_block_unpadded_size() after encoding or decoding the Block.
uncompressed_sizeUncompressed Size of a Block. This can be taken directly from lzma_block structure after encoding or decoding the Block.
+
+
+

Appending a new Block does not invalidate iterators. For example, if an iterator was pointing to the end of the lzma_index, after lzma_index_append() it is possible to read the next Block with an existing iterator.

+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK
    • +
  • LZMA_MEM_ERROR
    • +
  • LZMA_DATA_ERROR: Compressed or uncompressed size of the Stream or size of the Index field would grow too big.
    • +
  • LZMA_PROG_ERROR
    • +
+
+ +
+
+ +

◆ lzma_index_stream_flags()

+ +
+
+ + + + + + + + + + + + + + + + + + +
lzma_ret lzma_index_stream_flags (lzma_index * i,
const lzma_stream_flags * stream_flags 
)
+
+ +

Set the Stream Flags.

+

Set the Stream Flags of the last (and typically the only) Stream in lzma_index. This can be useful when reading information from the lzma_index, because to decode Blocks, knowing the integrity check type is needed.

+
Parameters
+ + + +
iPointer to lzma_index structure
stream_flagsPointer to lzma_stream_flags structure. This is copied into the internal preallocated structure, so the caller doesn't need to keep the flags' data available after calling this function.
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK
    • +
  • LZMA_OPTIONS_ERROR: Unsupported stream_flags->version.
    • +
  • LZMA_PROG_ERROR
    • +
+
+ +
+
+ +

◆ lzma_index_checks()

+ +
+
+ + + + + + + + +
uint32_t lzma_index_checks (const lzma_index * i)
+
+ +

Get the types of integrity Checks.

+

If lzma_index_stream_flags() is used to set the Stream Flags for every Stream, lzma_index_checks() can be used to get a bitmask to indicate which Check types have been used. It can be useful e.g. if showing the Check types to the user.

+

The bitmask is 1 << check_id, e.g. CRC32 is 1 << 1 and SHA-256 is 1 << 10.

+
Parameters
+ + +
iPointer to lzma_index structure
+
+
+
Returns
Bitmask indicating which Check types are used in the lzma_index
+ +
+
+ +

◆ lzma_index_stream_padding()

+ +
+
+ + + + + + + + + + + + + + + + + + +
lzma_ret lzma_index_stream_padding (lzma_index * i,
lzma_vli stream_padding 
)
+
+ +

Set the amount of Stream Padding.

+

Set the amount of Stream Padding of the last (and typically the only) Stream in the lzma_index. This is needed when planning to do random-access reading within multiple concatenated Streams.

+

By default, the amount of Stream Padding is assumed to be zero bytes.

+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK
    • +
  • LZMA_DATA_ERROR: The file size would grow too big.
    • +
  • LZMA_PROG_ERROR
    • +
+
+ +
+
+ +

◆ lzma_index_stream_count()

+ +
+
+ + + + + + + + +
lzma_vli lzma_index_stream_count (const lzma_index * i)
+
+ +

Get the number of Streams.

+
Parameters
+ + +
iPointer to lzma_index structure
+
+
+
Returns
Number of Streams in the lzma_index
+ +
+
+ +

◆ lzma_index_block_count()

+ +
+
+ + + + + + + + +
lzma_vli lzma_index_block_count (const lzma_index * i)
+
+ +

Get the number of Blocks.

+

This returns the total number of Blocks in lzma_index. To get number of Blocks in individual Streams, use lzma_index_iter.

+
Parameters
+ + +
iPointer to lzma_index structure
+
+
+
Returns
Number of blocks in the lzma_index
+ +
+
+ +

◆ lzma_index_size()

+ +
+
+ + + + + + + + +
lzma_vli lzma_index_size (const lzma_index * i)
+
+ +

Get the size of the Index field as bytes.

+

This is needed to verify the Backward Size field in the Stream Footer.

+
Parameters
+ + +
iPointer to lzma_index structure
+
+
+
Returns
Size in bytes of the Index
+ +
+
+ +

◆ lzma_index_stream_size()

+ +
+
+ + + + + + + + +
lzma_vli lzma_index_stream_size (const lzma_index * i)
+
+ +

Get the total size of the Stream.

+

If multiple lzma_indexes have been combined, this works as if the Blocks were in a single Stream. This is useful if you are going to combine Blocks from multiple Streams into a single new Stream.

+
Parameters
+ + +
iPointer to lzma_index structure
+
+
+
Returns
Size in bytes of the Stream (if all Blocks are combined into one Stream).
+ +
+
+ +

◆ lzma_index_total_size()

+ +
+
+ + + + + + + + +
lzma_vli lzma_index_total_size (const lzma_index * i)
+
+ +

Get the total size of the Blocks.

+

This doesn't include the Stream Header, Stream Footer, Stream Padding, or Index fields.

+
Parameters
+ + +
iPointer to lzma_index structure
+
+
+
Returns
Size in bytes of all Blocks in the Stream(s)
+ +
+
+ +

◆ lzma_index_file_size()

+ +
+
+ + + + + + + + +
lzma_vli lzma_index_file_size (const lzma_index * i)
+
+ +

Get the total size of the file.

+

When no lzma_indexes have been combined with lzma_index_cat() and there is no Stream Padding, this function is identical to lzma_index_stream_size(). If multiple lzma_indexes have been combined, this includes also the headers of each separate Stream and the possible Stream Padding fields.

+
Parameters
+ + +
iPointer to lzma_index structure
+
+
+
Returns
Total size of the .xz file in bytes
+ +
+
+ +

◆ lzma_index_uncompressed_size()

+ +
+
+ + + + + + + + +
lzma_vli lzma_index_uncompressed_size (const lzma_index * i)
+
+ +

Get the uncompressed size of the file.

+
Parameters
+ + +
iPointer to lzma_index structure
+
+
+
Returns
Size in bytes of the uncompressed data in the file
+ +
+
+ +

◆ lzma_index_iter_init()

+ +
+
+ + + + + + + + + + + + + + + + + + +
void lzma_index_iter_init (lzma_index_iter * iter,
const lzma_index * i 
)
+
+ +

Initialize an iterator.

+

This function associates the iterator with the given lzma_index, and calls lzma_index_iter_rewind() on the iterator.

+

This function doesn't allocate any memory, thus there is no lzma_index_iter_end(). The iterator is valid as long as the associated lzma_index is valid, that is, until lzma_index_end() or using it as source in lzma_index_cat(). Specifically, lzma_index doesn't become invalid if new Blocks are added to it with lzma_index_append() or if it is used as the destination in lzma_index_cat().

+

It is safe to make copies of an initialized lzma_index_iter, for example, to easily restart reading at some particular position.

+
Parameters
+ + + +
iterPointer to a lzma_index_iter structure
ilzma_index to which the iterator will be associated
+
+
+ +
+
+ +

◆ lzma_index_iter_rewind()

+ +
+
+ + + + + + + + +
void lzma_index_iter_rewind (lzma_index_iter * iter)
+
+ +

Rewind the iterator.

+

Rewind the iterator so that next call to lzma_index_iter_next() will return the first Block or Stream.

+
Parameters
+ + +
iterPointer to a lzma_index_iter structure
+
+
+ +
+
+ +

◆ lzma_index_iter_next()

+ +
+
+ + + + + + + + + + + + + + + + + + +
lzma_bool lzma_index_iter_next (lzma_index_iter * iter,
lzma_index_iter_mode mode 
)
+
+ +

Get the next Block or Stream.

+
Parameters
+ + + +
iterIterator initialized with lzma_index_iter_init()
modeSpecify what kind of information the caller wants to get. See lzma_index_iter_mode for details.
+
+
+
Returns
lzma_bool:
    +
  • true if no Block or Stream matching the mode is found. *iter is not updated (failure).
    • +
  • false if the next Block or Stream matching the mode was found. *iter is updated (success).
    • +
+
+ +
+
+ +

◆ lzma_index_iter_locate()

+ +
+
+ + + + + + + + + + + + + + + + + + +
lzma_bool lzma_index_iter_locate (lzma_index_iter * iter,
lzma_vli target 
)
+
+ +

Locate a Block.

+

If it is possible to seek in the .xz file, it is possible to parse the Index field(s) and use lzma_index_iter_locate() to do random-access reading with granularity of Block size.

+

If the target is smaller than the uncompressed size of the Stream (can be checked with lzma_index_uncompressed_size()):

    +
  • Information about the Stream and Block containing the requested uncompressed offset is stored into *iter.
    • +
  • Internal state of the iterator is adjusted so that lzma_index_iter_next() can be used to read subsequent Blocks or Streams.
    • +
+

If the target is greater than the uncompressed size of the Stream, *iter is not modified.

+
Parameters
+ + + +
iterIterator that was earlier initialized with lzma_index_iter_init().
targetUncompressed target offset which the caller would like to locate from the Stream
+
+
+
Returns
lzma_bool:
    +
  • true if the target is greater than or equal to the uncompressed size of the Stream (failure)
    • +
  • false if the target is smaller than the uncompressed size of the Stream (success)
    • +
+
+ +
+
+ +

◆ lzma_index_cat()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + +
lzma_ret lzma_index_cat (lzma_index * dest,
lzma_index * src,
const lzma_allocator * allocator 
)
+
+ +

Concatenate lzma_indexes.

+

Concatenating lzma_indexes is useful when doing random-access reading in multi-Stream .xz file, or when combining multiple Streams into single Stream.

+
Parameters
+ + + + +
[out]destlzma_index after which src is appended
srclzma_index to be appended after dest. If this function succeeds, the memory allocated for src is freed or moved to be part of dest, and all iterators pointing to src will become invalid.
allocatorlzma_allocator for custom allocator functions. Set to NULL to use malloc() and free().
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK: lzma_indexes were concatenated successfully. src is now a dangling pointer.
    • +
  • LZMA_DATA_ERROR: *dest would grow too big.
    • +
  • LZMA_MEM_ERROR
    • +
  • LZMA_PROG_ERROR
    • +
+
+ +
+
+ +

◆ lzma_index_dup()

+
+ + + + + + + + + + + + + + + + + + +
lzma_index * lzma_index_dup (const lzma_index * i,
const lzma_allocator * allocator 
)
+
+ +

Duplicate lzma_index.

+
Parameters
+ + + +
iPointer to lzma_index structure to be duplicated
allocatorlzma_allocator for custom allocator functions. Set to NULL to use malloc() and free().
+
+
+
Returns
A copy of the lzma_index, or NULL if memory allocation failed.
+ +
+
+ +

◆ lzma_index_encoder()

+ +
+
+ + + + + + + + + + + + + + + + + + +
lzma_ret lzma_index_encoder (lzma_stream * strm,
const lzma_index * i 
)
+
+ +

Initialize .xz Index encoder.

+
Parameters
+ + + +
strmPointer to properly prepared lzma_stream
iPointer to lzma_index which should be encoded.
+
+
+

The valid `action' values for lzma_code() are LZMA_RUN and LZMA_FINISH. It is enough to use only one of them (you can choose freely).

+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK: Initialization succeeded, continue with lzma_code().
    • +
  • LZMA_MEM_ERROR
    • +
  • LZMA_PROG_ERROR
    • +
+
+ +
+
+ +

◆ lzma_index_decoder()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + +
lzma_ret lzma_index_decoder (lzma_stream * strm,
lzma_index ** i,
uint64_t memlimit 
)
+
+ +

Initialize .xz Index decoder.

+
Parameters
+ + + + +
strmPointer to properly prepared lzma_stream
[out]iThe decoded Index will be made available via this pointer. Initially this function will set *i to NULL (the old value is ignored). If decoding succeeds (lzma_code() returns LZMA_STREAM_END), *i will be set to point to a new lzma_index, which the application has to later free with lzma_index_end().
memlimitHow much memory the resulting lzma_index is allowed to require. liblzma 5.2.3 and earlier don't allow 0 here and return LZMA_PROG_ERROR; later versions treat 0 as if 1 had been specified.
+
+
+

Valid `action' arguments to lzma_code() are LZMA_RUN and LZMA_FINISH. There is no need to use LZMA_FINISH, but it's allowed because it may simplify certain types of applications.

+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK: Initialization succeeded, continue with lzma_code().
    • +
  • LZMA_MEM_ERROR
    • +
  • LZMA_PROG_ERROR
    • +
+
+
Note
liblzma 5.2.3 and older list also LZMA_MEMLIMIT_ERROR here but that error code has never been possible from this initialization function.
+ +
+
+ +

◆ lzma_index_buffer_encode()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
lzma_ret lzma_index_buffer_encode (const lzma_index * i,
uint8_t * out,
size_t * out_pos,
size_t out_size 
)
+
+ +

Single-call .xz Index encoder.

+
Note
This function doesn't take allocator argument since all the internal data is allocated on stack.
+
Parameters
+ + + + + +
ilzma_index to be encoded
[out]outBeginning of the output buffer
[out]out_posThe next byte will be written to out[*out_pos]. *out_pos is updated only if encoding succeeds.
out_sizeSize of the out buffer; the first byte into which no data is written to is out[out_size].
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK: Encoding was successful.
    • +
  • LZMA_BUF_ERROR: Output buffer is too small. Use lzma_index_size() to find out how much output space is needed.
    • +
  • LZMA_PROG_ERROR
    • +
+
+ +
+
+ +

◆ lzma_index_buffer_decode()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
lzma_ret lzma_index_buffer_decode (lzma_index ** i,
uint64_t * memlimit,
const lzma_allocator * allocator,
const uint8_t * in,
size_t * in_pos,
size_t in_size 
)
+
+ +

Single-call .xz Index decoder.

+
Parameters
+ + + + + + + +
[out]iIf decoding succeeds, *i will point to a new lzma_index, which the application has to later free with lzma_index_end(). If an error occurs, *i will be NULL. The old value of *i is always ignored and thus doesn't need to be initialized by the caller.
[out]memlimitPointer to how much memory the resulting lzma_index is allowed to require. The value pointed by this pointer is modified if and only if LZMA_MEMLIMIT_ERROR is returned.
allocatorlzma_allocator for custom allocator functions. Set to NULL to use malloc() and free().
inBeginning of the input buffer
in_posThe next byte will be read from in[*in_pos]. *in_pos is updated only if decoding succeeds.
in_sizeSize of the input buffer; the first byte that won't be read is in[in_size].
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK: Decoding was successful.
    • +
  • LZMA_MEM_ERROR
    • +
  • LZMA_MEMLIMIT_ERROR: Memory usage limit was reached. The minimum required memlimit value was stored to *memlimit.
    • +
  • LZMA_DATA_ERROR
    • +
  • LZMA_PROG_ERROR
    • +
+
+ +
+
+ +

◆ lzma_file_info_decoder()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
lzma_ret lzma_file_info_decoder (lzma_stream * strm,
lzma_index ** dest_index,
uint64_t memlimit,
uint64_t file_size 
)
+
+ +

Initialize a .xz file information decoder.

+

This decoder decodes the Stream Header, Stream Footer, Index, and Stream Padding field(s) from the input .xz file and stores the resulting combined index in *dest_index. This information can be used to get the uncompressed file size with lzma_index_uncompressed_size(*dest_index) or, for example, to implement random access reading by locating the Blocks in the Streams.

+

To get the required information from the .xz file, lzma_code() may ask the application to seek in the input file by returning LZMA_SEEK_NEEDED and having the target file position specified in lzma_stream.seek_pos. The number of seeks required depends on the input file and how big buffers the application provides. When possible, the decoder will seek backward and forward in the given buffer to avoid useless seek requests. Thus, if the application provides the whole file at once, no external seeking will be required (that is, lzma_code() won't return LZMA_SEEK_NEEDED).

+

The value in lzma_stream.total_in can be used to estimate how much data liblzma had to read to get the file information. However, due to seeking and the way total_in is updated, the value of total_in will be somewhat inaccurate (a little too big). Thus, total_in is a good estimate but don't expect to see the same exact value for the same file if you change the input buffer size or switch to a different liblzma version.

+

Valid `action' arguments to lzma_code() are LZMA_RUN and LZMA_FINISH. You only need to use LZMA_RUN; LZMA_FINISH is only supported because it might be convenient for some applications. If you use LZMA_FINISH and if lzma_code() asks the application to seek, remember to reset `action' back to LZMA_RUN unless you hit the end of the file again.

+

Possible return values from lzma_code():

    +
  • LZMA_OK: All OK so far, more input needed
    • +
  • LZMA_SEEK_NEEDED: Provide more input starting from the absolute file position strm->seek_pos
    • +
  • LZMA_STREAM_END: Decoding was successful, *dest_index has been set
    • +
  • LZMA_FORMAT_ERROR: The input file is not in the .xz format (the expected magic bytes were not found from the beginning of the file)
    • +
  • LZMA_OPTIONS_ERROR: File looks valid but contains headers that aren't supported by this version of liblzma
    • +
  • LZMA_DATA_ERROR: File is corrupt
    • +
  • LZMA_BUF_ERROR
    • +
  • LZMA_MEM_ERROR
    • +
  • LZMA_MEMLIMIT_ERROR
    • +
  • LZMA_PROG_ERROR
    • +
+
Parameters
+ + + + + +
strmPointer to a properly prepared lzma_stream
[out]dest_indexPointer to a pointer where the decoder will put the decoded lzma_index. The old value of *dest_index is ignored (not freed).
memlimitHow much memory the resulting lzma_index is allowed to require. Use UINT64_MAX to effectively disable the limiter.
file_sizeSize of the input .xz file
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK
    • +
  • LZMA_MEM_ERROR
    • +
  • LZMA_PROG_ERROR

Note
Never include this file directly. Use <lzma.h> instead.
+

Hashing makes it possible to use constant amount of memory to validate Index of arbitrary size.

+

Function Documentation

+ +

◆ lzma_index_hash_init()

+ +
+
+ + + + + + + + + + + + + + + + + + +
lzma_index_hash * lzma_index_hash_init (lzma_index_hash * index_hash,
const lzma_allocator * allocator 
)
+
+ +

Allocate and initialize a new lzma_index_hash structure.

+

If index_hash is NULL, this function allocates and initializes a new lzma_index_hash structure and returns a pointer to it. If allocation fails, NULL is returned.

+

If index_hash is non-NULL, this function reinitializes the lzma_index_hash structure and returns the same pointer. In this case, return value cannot be NULL or a different pointer than the index_hash that was given as an argument.

+
Parameters
+ + + +
index_hashPointer to a lzma_index_hash structure or NULL.
allocatorlzma_allocator for custom allocator functions. Set to NULL to use malloc() and free().
+
+
+
Returns
Initialized lzma_index_hash structure on success or NULL on failure.
+ +
+
+ +

◆ lzma_index_hash_end()

+ +
+
+ + + + + + + + + + + + + + + + + + +
void lzma_index_hash_end (lzma_index_hash * index_hash,
const lzma_allocator * allocator 
)
+
+ +

Deallocate lzma_index_hash structure.

+
Parameters
+ + + +
index_hashPointer to a lzma_index_hash structure to free.
allocatorlzma_allocator for custom allocator functions. Set to NULL to use malloc() and free().
+
+
+ +
+
+ +

◆ lzma_index_hash_append()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + +
lzma_ret lzma_index_hash_append (lzma_index_hash * index_hash,
lzma_vli unpadded_size,
lzma_vli uncompressed_size 
)
+
+ +

Add a new Record to an Index hash.

+
Parameters
+ + + + +
index_hashPointer to a lzma_index_hash structure
unpadded_sizeUnpadded Size of a Block
uncompressed_sizeUncompressed Size of a Block
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK
    • +
  • LZMA_DATA_ERROR: Compressed or uncompressed size of the Stream or size of the Index field would grow too big.
    • +
  • LZMA_PROG_ERROR: Invalid arguments or this function is being used when lzma_index_hash_decode() has already been used.
    • +
+
+ +
+
+ +

◆ lzma_index_hash_decode()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
lzma_ret lzma_index_hash_decode (lzma_index_hash * index_hash,
const uint8_t * in,
size_t * in_pos,
size_t in_size 
)
+
+ +

Decode and validate the Index field.

+

After telling the sizes of all Blocks with lzma_index_hash_append(), the actual Index field is decoded with this function. Specifically, once decoding of the Index field has been started, no more Records can be added using lzma_index_hash_append().

+

This function doesn't use lzma_stream structure to pass the input data. Instead, the input buffer is specified using three arguments. This is because it matches better the internal APIs of liblzma.

+
Parameters
+ + + + + +
index_hashPointer to a lzma_index_hash structure
inPointer to the beginning of the input buffer
[out]in_posin[*in_pos] is the next byte to process
in_sizein[in_size] is the first byte not to process
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK: So far good, but more input is needed.
    • +
  • LZMA_STREAM_END: Index decoded successfully and it matches the Records given with lzma_index_hash_append().
    • +

Detailed Description

+

LZMA1 and LZMA2 filters.

+
Note
Never include this file directly. Use <lzma.h> instead.
+

Macro Definition Documentation

+ +

◆ LZMA_FILTER_LZMA1

+ +
+
+ + + + +
#define LZMA_FILTER_LZMA1   LZMA_VLI_C(0x4000000000000001)
+
+ +

LZMA1 Filter ID (for raw encoder/decoder only, not in .xz)

+

LZMA1 is the very same thing as what was called just LZMA in LZMA Utils, 7-Zip, and LZMA SDK. It's called LZMA1 here to prevent developers from accidentally using LZMA when they actually want LZMA2.

+ +
+
+ +

◆ LZMA_FILTER_LZMA1EXT

+ +
+
+ + + + +
#define LZMA_FILTER_LZMA1EXT   LZMA_VLI_C(0x4000000000000002)
+
+ +

LZMA1 Filter ID with extended options (for raw encoder/decoder)

+

This is like LZMA_FILTER_LZMA1 but with this ID a few extra options are supported in the lzma_options_lzma structure:

+
    +
  • A flag to tell the encoder if the end of payload marker (EOPM) alias end of stream (EOS) marker must be written at the end of the stream. In contrast, LZMA_FILTER_LZMA1 always writes the end marker.
    • +
  • Decoder needs to be told the uncompressed size of the stream or that it is unknown (using the special value UINT64_MAX). If the size is known, a flag can be set to allow the presence of the end marker anyway. In contrast, LZMA_FILTER_LZMA1 always behaves as if the uncompressed size was unknown.
    • +
+

This allows handling file formats where LZMA1 streams are used but where the end marker isn't allowed or where it might not (always) be present. This extended LZMA1 functionality is provided as a Filter ID for raw encoder and decoder instead of adding new encoder and decoder initialization functions because this way it is possible to also use extra filters, for example, LZMA_FILTER_X86 in a filter chain with LZMA_FILTER_LZMA1EXT, which might be needed to handle some file formats.

+ +
+
+ +

◆ LZMA_FILTER_LZMA2

+ +
+
+ + + + +
#define LZMA_FILTER_LZMA2   LZMA_VLI_C(0x21)
+
+ +

LZMA2 Filter ID.

+

Usually you want this instead of LZMA1. Compared to LZMA1, LZMA2 adds support for LZMA_SYNC_FLUSH, uncompressed chunks (smaller expansion when trying to compress incompressible data), possibility to change lc/lp/pb in the middle of encoding, and some other internal improvements.

+ +
+
+ +

◆ lzma_set_ext_size

+ +
+
+ + + + + + + + + + + + + + + + + + +
#define lzma_set_ext_size( opt_lzma2,
 u64size 
)
+
+Value:
do { \
+
(opt_lzma2).ext_size_low = (uint32_t)(u64size); \
+
(opt_lzma2).ext_size_high = (uint32_t)((uint64_t)(u64size) >> 32); \
+
} while (0)
+
+

Macro to set the 64-bit uncompressed size in ext_size_*.

+

This might be convenient when decoding using LZMA_FILTER_LZMA1EXT. This isn't used with LZMA_FILTER_LZMA1 or LZMA_FILTER_LZMA2.

+ +
+
+

Enumeration Type Documentation

+ +

◆ lzma_match_finder

+ +
+
+ + + + +
enum lzma_match_finder
+
+ +

Match finders.

+

Match finder has major effect on both speed and compression ratio. Usually hash chains are faster than binary trees.

+

If you will use LZMA_SYNC_FLUSH often, the hash chains may be a better choice, because binary trees get much higher compression ratio penalty with LZMA_SYNC_FLUSH.

+

The memory usage formulas are only rough estimates, which are closest to reality when dict_size is a power of two. The formulas are more complex in reality, and can also change a little between liblzma versions. Use lzma_raw_encoder_memusage() to get more accurate estimate of memory usage.

+ + + + + + +
Enumerator
LZMA_MF_HC3 

Hash Chain with 2- and 3-byte hashing.

+

Minimum nice_len: 3

+

Memory usage:

    +
  • dict_size <= 16 MiB: dict_size * 7.5
    • +
  • dict_size > 16 MiB: dict_size * 5.5 + 64 MiB
    • +
+
LZMA_MF_HC4 

Hash Chain with 2-, 3-, and 4-byte hashing.

+

Minimum nice_len: 4

+

Memory usage:

    +
  • dict_size <= 32 MiB: dict_size * 7.5
    • +
  • dict_size > 32 MiB: dict_size * 6.5
    • +
+
LZMA_MF_BT2

+

Minimum nice_len: 2

+

Memory usage: dict_size * 9.5

+
LZMA_MF_BT3 

Binary Tree with 2- and 3-byte hashing.

+

Minimum nice_len: 3

+

Memory usage:

    +
  • dict_size <= 16 MiB: dict_size * 11.5
    • +
  • dict_size > 16 MiB: dict_size * 9.5 + 64 MiB
    • +
+
LZMA_MF_BT4

    • +
+
+ +
+
+ +

◆ lzma_mode

+ +
+
+ + + + +
enum lzma_mode
+
+ +

Compression modes.

+

This selects the function used to analyze the data produced by the match finder.

+ + + +
Enumerator
LZMA_MODE_FAST 

Fast compression.

+

Fast mode is usually at its best when combined with a hash chain match finder.

+
LZMA_MODE_NORMAL 

Normal compression.

+

This is usually notably slower than fast mode. Use this together with binary tree match finders to expose the full potential of the LZMA1 or LZMA2 encoder.

+
+ +
+
+

Function Documentation

+ +

◆ lzma_mf_is_supported()

+ +
+
+ + + + + + + + +
lzma_bool lzma_mf_is_supported (lzma_match_finder match_finder) const
+
+ +

Test if given match finder is supported.

+

It is safe to call this with a value that isn't listed in lzma_match_finder enumeration; the return value will be false.

+

There is no way to list which match finders are available in this particular liblzma version and build. It would be useless, because a new match finder, which the application developer wasn't aware, could require giving additional options to the encoder that the older match finders don't need.

+
Parameters
+ + +
match_finderMatch finder ID
+
+
+
Returns
lzma_bool:
    +
  • true if the match finder is supported by this liblzma build.
    • +
  • false otherwise.
    • +
+
+ +
+
+ +

◆ lzma_mode_is_supported()

+ +
+
+ + + + + + + + +
lzma_bool lzma_mode_is_supported (lzma_mode mode) const
+
+ +

Test if given compression mode is supported.

+

It is safe to call this with a value that isn't listed in lzma_mode enumeration; the return value will be false.

+

There is no way to list which modes are available in this particular liblzma version and build. It would be useless, because a new compression mode, which the application developer wasn't aware, could require giving additional options to the encoder that the older modes don't need.

+
Parameters
+ + +
modeMode ID.
+
+
+
Returns
lzma_bool:
    +
  • true if the compression mode is supported by this liblzma build.
    • +
  • false otherwise.
    • +
+
+ +
+
+ +

◆ lzma_lzma_preset()

+ +
+
+ + + + + + + + + + + + + + + + + + +
lzma_bool lzma_lzma_preset (lzma_options_lzma * options,
uint32_t preset 
)
+
+ +

Set a compression preset to lzma_options_lzma structure.

+

0 is the fastest and 9 is the slowest. These match the switches -0 .. -9 of the xz command line tool. In addition, it is possible to bitwise-or flags to the preset. Currently only LZMA_PRESET_EXTREME is supported. The flags are defined in container.h, because the flags are used also with lzma_easy_encoder().

+

The preset levels are subject to changes between liblzma versions.

+

This function is available only if LZMA1 or LZMA2 encoder has been enabled when building liblzma.

+

If features (like certain match finders) have been disabled at build time, then the function may return success (false) even though the resulting LZMA1/LZMA2 options may not be usable for encoder initialization (LZMA_OPTIONS_ERROR).

+
Parameters
+ + + +
[out]optionsPointer to LZMA1 or LZMA2 options to be filled
presetPreset level bitwse-ORed with preset flags
+
+
+
Returns
lzma_bool:
    +
  • true if the preset is not supported (failure).
    • +
  • false otherwise (success).

◆ LZMA_STREAM_HEADER_SIZE

+ +
+
+ + + + +
#define LZMA_STREAM_HEADER_SIZE   12

Size of Stream Header and Stream Footer.

+

Stream Header and Stream Footer have the same size and they are not going to change even if a newer version of the .xz file format is developed in future.

+ +
+
+

Function Documentation

◆ lzma_stream_header_encode()

+ +
+
+ + + + + + + + + + + + + + + + + + +
lzma_ret lzma_stream_header_encode (const lzma_stream_flags * options,
uint8_t * out 
)
+
+ +

Encode Stream Header.

+
Parameters
+ + + +
optionsStream Header options to be encoded. options->backward_size is ignored and doesn't need to be initialized.
[out]outBeginning of the output buffer of LZMA_STREAM_HEADER_SIZE bytes.
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK: Encoding was successful.
    • +
  • LZMA_OPTIONS_ERROR: options->version is not supported by this liblzma version.
    • +
  • LZMA_PROG_ERROR: Invalid options.
    • +
+
+ +
+
+ +

◆ lzma_stream_footer_encode()

+
+ + + + + + + + + + + + + + + + + + +
lzma_ret lzma_stream_footer_encode (const lzma_stream_flags * options,
uint8_t * out 
)
+
+ +

Encode Stream Footer.

+
Parameters
+ + + +
optionsStream Footer options to be encoded.
[out]outBeginning of the output buffer of LZMA_STREAM_HEADER_SIZE bytes.
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK: Encoding was successful.
    • +
  • LZMA_OPTIONS_ERROR: options->version is not supported by this liblzma version.
    • +
  • LZMA_PROG_ERROR: Invalid options.
    • +
+
+ +
+
+ +

◆ lzma_stream_header_decode()

+ +
+
+ + + + + + + + + + + + + + + + + + +
lzma_ret lzma_stream_header_decode (lzma_stream_flags * options,
const uint8_t * in 
)
+
+ +

Decode Stream Header.

+

options->backward_size is always set to LZMA_VLI_UNKNOWN. This is to help comparing Stream Flags from Stream Header and Stream Footer with lzma_stream_flags_compare().

+
Note
When decoding .xz files that contain multiple Streams, it may make sense to print "file format not recognized" only if decoding of the Stream Header of the first Stream gives LZMA_FORMAT_ERROR. If non-first Stream Header gives LZMA_FORMAT_ERROR, the message used for LZMA_DATA_ERROR is probably more appropriate. For example, the Stream decoder in liblzma uses LZMA_DATA_ERROR if LZMA_FORMAT_ERROR is returned by lzma_stream_header_decode() when decoding non-first Stream.
+
Parameters
+ + + +
[out]optionsTarget for the decoded Stream Header options.
inBeginning of the input buffer of LZMA_STREAM_HEADER_SIZE bytes.
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK: Decoding was successful.
    • +
  • LZMA_FORMAT_ERROR: Magic bytes don't match, thus the given buffer cannot be Stream Header.
    • +
  • LZMA_DATA_ERROR: CRC32 doesn't match, thus the header is corrupt.
    • +
  • LZMA_OPTIONS_ERROR: Unsupported options are present in the header.
    • +
+
+ +
+
+ +

◆ lzma_stream_footer_decode()

+ +
+
+ + + + + + + + + + + + + + + + + + +
lzma_ret lzma_stream_footer_decode (lzma_stream_flags * options,
const uint8_t * in 
)
+
+ +

Decode Stream Footer.

+
Note
If Stream Header was already decoded successfully, but decoding Stream Footer returns LZMA_FORMAT_ERROR, the application should probably report some other error message than "file format not recognized". The file likely is corrupt (possibly truncated). The Stream decoder in liblzma uses LZMA_DATA_ERROR in this situation.
+
Parameters
+ + + +
[out]optionsTarget for the decoded Stream Footer options.
inBeginning of the input buffer of LZMA_STREAM_HEADER_SIZE bytes.
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK: Decoding was successful.
    • +
  • LZMA_FORMAT_ERROR: Magic bytes don't match, thus the given buffer cannot be Stream Footer.
    • +
  • LZMA_DATA_ERROR: CRC32 doesn't match, thus the Stream Footer is corrupt.
    • +
  • LZMA_OPTIONS_ERROR: Unsupported options are present in Stream Footer.
    • +
+
+ +
+
+ +

◆ lzma_stream_flags_compare()

+ +
+
+ + + + + + + + + + + + + + + + + + +
lzma_ret lzma_stream_flags_compare (const lzma_stream_flags * a,
const lzma_stream_flags * b 
)
+
+ +

Compare two lzma_stream_flags structures.

+

backward_size values are compared only if both are not LZMA_VLI_UNKNOWN.

+
Parameters
+ + + +
aPointer to lzma_stream_flags structure
bPointer to lzma_stream_flags structure
+
+
+
Returns
Possible lzma_ret values:
    +
  • LZMA_OK: Both are equal. If either had backward_size set to LZMA_VLI_UNKNOWN, backward_size values were not compared or validated.
    • +
  • LZMA_DATA_ERROR: The structures differ.
    • +
  • LZMA_OPTIONS_ERROR: version in either structure is greater than the maximum supported version (currently zero).
    • +
  • LZMA_PROG_ERROR: Invalid value, e.g. invalid check or backward_size.

Detailed Description

+

Custom functions for memory handling.

+

A pointer to lzma_allocator may be passed via lzma_stream structure to liblzma, and some advanced functions take a pointer to lzma_allocator as a separate function argument. The library will use the functions specified in lzma_allocator for memory handling instead of the default malloc() and free(). C++ users should note that the custom memory handling functions must not throw exceptions.

+

Single-threaded mode only: liblzma doesn't make an internal copy of lzma_allocator. Thus, it is OK to change these function pointers in the middle of the coding process, but obviously it must be done carefully to make sure that the replacement `free' can deallocate memory allocated by the earlier `alloc' function(s).

+

Multithreaded mode: liblzma might internally store pointers to the lzma_allocator given via the lzma_stream structure. The application must not change the allocator pointer in lzma_stream or the contents of the pointed lzma_allocator structure until lzma_end() has been used to free the memory associated with that lzma_stream. The allocation functions might be called simultaneously from multiple threads, and thus they must be thread safe.

+

Field Documentation

+ +

◆ alloc

+ +
+
+ + + + +
void *(* lzma_allocator::alloc) (void *opaque, size_t nmemb, size_t size)
+
+ +

Pointer to a custom memory allocation function.

+

If you don't want a custom allocator, but still want custom free(), set this to NULL and liblzma will use the standard malloc().

+
Parameters
+ + + + +
opaquelzma_allocator.opaque (see below)
nmembNumber of elements like in calloc(). liblzma will always set nmemb to 1, so it is safe to ignore nmemb in a custom allocator if you like. The nmemb argument exists only for compatibility with zlib and libbzip2.
sizeSize of an element in bytes. liblzma never sets this to zero.
+
+
+
Returns
Pointer to the beginning of a memory block of `size' bytes, or NULL if allocation fails for some reason. When allocation fails, functions of liblzma return LZMA_MEM_ERROR.
+

The allocator should not waste time zeroing the allocated buffers. This is not only about speed, but also memory usage, since the operating system kernel doesn't necessarily allocate the requested memory in physical memory until it is actually used. With small input files, liblzma may actually need only a fraction of the memory that it requested for allocation.

+
Note
LZMA_MEM_ERROR is also used when the size of the allocation would be greater than SIZE_MAX. Thus, don't assume that the custom allocator must have returned NULL if some function from liblzma returns LZMA_MEM_ERROR.
+ +
+
+ +

◆ free

+ +
+
+ + + + +
void(* lzma_allocator::free) (void *opaque, void *ptr)
+
+ +

Pointer to a custom memory freeing function.

+

If you don't want a custom freeing function, but still want a custom allocator, set this to NULL and liblzma will use the standard free().

+
Parameters
+ + + +
opaquelzma_allocator.opaque (see below)
ptrPointer returned by lzma_allocator.alloc(), or when it is set to NULL, a pointer returned by the standard malloc().
+
+
+ +
+
+ +

◆ opaque

+ +
+
+ + + + +
void* lzma_allocator::opaque
+
+ +

Pointer passed to .alloc() and .free()

+

opaque is passed as the first argument to lzma_allocator.alloc() and lzma_allocator.free(). This intended to ease implementing custom memory allocation functions for use with liblzma.

+

If you don't need this, you should set this to NULL.

Detailed Description

+

Options for the Block and Block Header encoders and decoders.

+

Different Block handling functions use different parts of this structure. Some read some members, other functions write, and some do both. Only the members listed for reading need to be initialized when the specified functions are called. The members marked for writing will be assigned new values at some point either by calling the given function or by later calls to lzma_code().

+

Field Documentation

+ +

◆ version

+ +
+
+ + + + +
uint32_t lzma_block::version
+
+ +

Block format version.

+

To prevent API and ABI breakages when new features are needed, a version number is used to indicate which members in this structure are in use:

    +
  • liblzma >= 5.0.0: version = 0 is supported.
    • +
  • liblzma >= 5.1.4beta: Support for version = 1 was added, which adds the ignore_check member.
    • +
+

If version is greater than one, most Block related functions will return LZMA_OPTIONS_ERROR (lzma_block_header_decode() works with any version value).

◆ header_size

+ +
+
+ + + + +
uint32_t lzma_block::header_size
+
+ +

Size of the Block Header field in bytes.

+

This is always a multiple of four.

◆ check

+ +
+
+ + + + +
lzma_check lzma_block::check
+
+ +

Type of integrity Check.

+

The Check ID is not stored into the Block Header, thus its value must be provided also when decoding.

+

Read by:

+ +
+
+ +

◆ compressed_size

+ +
+
+ + + + +
lzma_vli lzma_block::compressed_size
+
+ +

Size of the Compressed Data in bytes.

+

Encoding: If this is not LZMA_VLI_UNKNOWN, Block Header encoder will store this value to the Block Header. Block encoder doesn't care about this value, but will set it once the encoding has been finished.

+

Decoding: If this is not LZMA_VLI_UNKNOWN, Block decoder will verify that the size of the Compressed Data field matches compressed_size.

+

Usually you don't know this value when encoding in streamed mode, and thus cannot write this field into the Block Header.

+

In non-streamed mode you can reserve space for this field before encoding the actual Block. After encoding the data, finish the Block by encoding the Block Header. Steps in detail:

+
    +
  • Set compressed_size to some big enough value. If you don't know better, use LZMA_VLI_MAX, but remember that bigger values take more space in Block Header.
    • +
  • Call lzma_block_header_size() to see how much space you need to reserve for the Block Header.
    • +
  • Encode the Block using lzma_block_encoder() and lzma_code(). It sets compressed_size to the correct value.
    • +
  • Use lzma_block_header_encode() to encode the Block Header. Because space was reserved in the first step, you don't need to call lzma_block_header_size() anymore, because due to reserving, header_size has to be big enough. If it is "too big", lzma_block_header_encode() will add enough Header Padding to make Block Header to match the size specified by header_size.

◆ uncompressed_size

+ +
+
+ + + + +
lzma_vli lzma_block::uncompressed_size
+
+ +

Uncompressed Size in bytes.

+

This is handled very similarly to compressed_size above.

+

uncompressed_size is needed by fewer functions than compressed_size. This is because uncompressed_size isn't needed to validate that Block stays within proper limits.

◆ filters

+ +
+
+ + + + +
lzma_filter* lzma_block::filters
+
+ +

Array of filters.

+

There can be 1-4 filters. The end of the array is marked with .id = LZMA_VLI_UNKNOWN.

+

Read by:

+

Written by:

    +
  • lzma_block_header_decode(): Note that this does NOT free() the old filter options structures. All unused filters[] will have .id == LZMA_VLI_UNKNOWN and .options == NULL. If decoding fails, all filters[] are guaranteed to be LZMA_VLI_UNKNOWN and NULL.
    • +
+
Note
Because of the array is terminated with .id = LZMA_VLI_UNKNOWN, the actual array must have LZMA_FILTERS_MAX + 1 members or the Block Header decoder will overflow the buffer.
+ +
+
+ +

◆ raw_check

+ +
+
+ + + + +
uint8_t lzma_block::raw_check[LZMA_CHECK_SIZE_MAX]
+
+ +

Raw value stored in the Check field.

+

After successful coding, the first lzma_check_size(check) bytes of this array contain the raw value stored in the Check field.

+

Note that CRC32 and CRC64 are stored in little endian byte order. Take it into account if you display the Check values to the user.

+

Written by:

+ +
+
+ +

◆ ignore_check

+ +
+
+ + + + +
lzma_bool lzma_block::ignore_check
+
+ +

A flag to Block decoder to not verify the Check field.

+

This member is supported by liblzma >= 5.1.4beta if .version >= 1.

+

If this is set to true, the integrity check won't be calculated and verified. Unless you know what you are doing, you should leave this to false. (A reason to set this to true is when the file integrity is verified externally anyway and you want to speed up the decompression, which matters mostly when using SHA-256 as the integrity check.)

Detailed Description

+

Filter options.

+

This structure is used to pass a Filter ID and a pointer to the filter's options to liblzma. A few functions work with a single lzma_filter structure, while most functions expect a filter chain.

+

A filter chain is indicated with an array of lzma_filter structures. The array is terminated with .id = LZMA_VLI_UNKNOWN. Thus, the filter array must have LZMA_FILTERS_MAX + 1 elements (that is, five) to be able to hold any arbitrary filter chain. This is important when using lzma_block_header_decode() from block.h, because a filter array that is too small would make liblzma write past the end of the array.

+

Field Documentation

+ +

◆ id

+ +
+
+ + + + +
lzma_vli lzma_filter::id
+
+ +

Filter ID.

+

Use constants whose name begin with `LZMA_FILTER_' to specify different filters. In an array of lzma_filter structures, use LZMA_VLI_UNKNOWN to indicate end of filters.

+
Note
This is not an enum, because on some systems enums cannot be 64-bit.
+ +
+
+ +

◆ options

+ +
+
+ + + + +
void* lzma_filter::options
+
+ +

Pointer to filter-specific options structure.

+

If the filter doesn't need options, set this to NULL. If id is set to LZMA_VLI_UNKNOWN, options is ignored, and thus doesn't need be initialized.

◆ flags

+ +
+
+ + + + +
const lzma_stream_flags* lzma_index_iter::flags
+
+ +

Pointer to Stream Flags.

+

This is NULL if Stream Flags have not been set for this Stream with lzma_index_stream_flags().

+ +
+
+ +

◆ number

+ +
+
+ + + + +
lzma_vli lzma_index_iter::number
+
+ +

Stream number in the lzma_index.

+

The first Stream is 1.

+ +
+
+ +

◆ block_count

+ +
+
+ + + + +
lzma_vli lzma_index_iter::block_count
+
+ +

Number of Blocks in the Stream.

+

If this is zero, the block structure below has undefined values.

+ +
+
+ +

◆ compressed_offset

+ +
+
+ + + + +
lzma_vli lzma_index_iter::compressed_offset
+
+ +

Compressed start offset of this Stream.

+

The offset is relative to the beginning of the lzma_index (i.e. usually the beginning of the .xz file).

+ +
+
+ +

◆ uncompressed_offset

+ +
+
+ + + + +
lzma_vli lzma_index_iter::uncompressed_offset
+
+ +

Uncompressed start offset of this Stream.

+

The offset is relative to the beginning of the lzma_index (i.e. usually the beginning of the .xz file).

+ +
+
+ +

◆ compressed_size

+ +
+
+ + + + +
lzma_vli lzma_index_iter::compressed_size
+
+ +

Compressed size of this Stream.

+

This includes all headers except the possible Stream Padding after this Stream.

+ +
+
+ +

◆ uncompressed_size

+ +
+
+ + + + +
lzma_vli lzma_index_iter::uncompressed_size
+
+ +

Uncompressed size of this Stream.

+

Uncompressed size of this Block.

+

You should pass this to the Block decoder if you will decode this Block. It will allow the Block decoder to validate the uncompressed size.

+ +
+
+ +

◆ padding

+ +
+
+ + + + +
lzma_vli lzma_index_iter::padding
+
+ +

Size of Stream Padding after this Stream.

+

If it hasn't been set with lzma_index_stream_padding(), this defaults to zero. Stream Padding is always a multiple of four bytes.

+ +
+
+ +

◆ number_in_file

+ +
+
+ + + + +
lzma_vli lzma_index_iter::number_in_file

◆ compressed_file_offset

+ +
+
+ + + + +
lzma_vli lzma_index_iter::compressed_file_offset
+
+ +

Compressed start offset of this Block.

+

This offset is relative to the beginning of the lzma_index (i.e. usually the beginning of the .xz file). Normally this is where you should seek in the .xz file to start decompressing this Block.

◆ uncompressed_file_offset

+ +
+
+ + + + +
lzma_vli lzma_index_iter::uncompressed_file_offset
+
+ +

Uncompressed start offset of this Block.

+

This offset is relative to the beginning of the lzma_index (i.e. usually the beginning of the .xz file).

+

When doing random-access reading, it is possible that the target offset is not exactly at Block boundary. One will need to compare the target offset against uncompressed_file_offset or uncompressed_stream_offset, and possibly decode and throw away some amount of data before reaching the target offset.

+ +
+
+ +

◆ number_in_stream

+ +
+
+ + + + +
lzma_vli lzma_index_iter::number_in_stream
+
+ +

+ +

Compressed start offset of this Block.

+

This offset is relative to the beginning of the Stream containing this Block.

+ +

+
+ +

◆ total_size

+ +
+
+ + + + +
lzma_vli lzma_index_iter::total_size
+
+ +

Total compressed size.

+

This includes all headers and padding in this Block. This is useful if you need to know how many bytes the Block decoder will actually read.

Detailed Description

Field Documentation

+ +

◆ flags

+ +
+
+ + + + +
uint32_t lzma_mt::flags
+
+ +

Flags.

+

Set this to zero if no flags are wanted.

+

Encoder: No flags are currently supported.

+

Decoder: Bitwise-or of zero or more of the decoder flags:

    +
  • LZMA_TELL_NO_CHECK
    • +
  • LZMA_TELL_UNSUPPORTED_CHECK
    • +
  • LZMA_TELL_ANY_CHECK
    • +
  • LZMA_IGNORE_CHECK
    • +
  • LZMA_CONCATENATED
    • +
  • LZMA_FAIL_FAST
    • +
+ +
+
+ +

◆ block_size

+ +
+
+ + + + +
uint64_t lzma_mt::block_size
+
+ +

Encoder only: Maximum uncompressed size of a Block.

+

The encoder will start a new .xz Block every block_size bytes. Using LZMA_FULL_FLUSH or LZMA_FULL_BARRIER with lzma_code() the caller may tell liblzma to start a new Block earlier.

+

With LZMA2, a recommended block size is 2-4 times the LZMA2 dictionary size. With very small dictionaries, it is recommended to use at least 1 MiB block size for good compression ratio, even if this is more than four times the dictionary size. Note that these are only recommendations for typical use cases; feel free to use other values. Just keep in mind that using a block size less than the LZMA2 dictionary size is waste of RAM.

+

Set this to 0 to let liblzma choose the block size depending on the compression options. For LZMA2 it will be 3*dict_size or 1 MiB, whichever is more.

+

For each thread, about 3 * block_size bytes of memory will be allocated. This may change in later liblzma versions. If so, the memory usage will probably be reduced, not increased.

+ +
+
+ +

◆ timeout

+ +
+
+ + + + +
uint32_t lzma_mt::timeout
+
+ +

Timeout to allow lzma_code() to return early.

+

Multithreading can make liblzma consume input and produce output in a very bursty way: it may first read a lot of input to fill internal buffers, then no input or output occurs for a while.

+

In single-threaded mode, lzma_code() won't return until it has either consumed all the input or filled the output buffer. If this is done in multithreaded mode, it may cause a call lzma_code() to take even tens of seconds, which isn't acceptable in all applications.

+

To avoid very long blocking times in lzma_code(), a timeout (in milliseconds) may be set here. If lzma_code() would block longer than this number of milliseconds, it will return with LZMA_OK. Reasonable values are 100 ms or more. The xz command line tool uses 300 ms.

+

If long blocking times are acceptable, set timeout to a special value of 0. This will disable the timeout mechanism and will make lzma_code() block until all the input is consumed or the output buffer has been filled.

+
Note
Even with a timeout, lzma_code() might sometimes take a long time to return. No timing guarantees are made.
+ +
+
+ +

◆ preset

+ +
+
+ + + + +
uint32_t lzma_mt::preset
+
+ +

Encoder only: Compression preset.

+

The preset is set just like with lzma_easy_encoder(). The preset is ignored if filters below is non-NULL.

+ +
+
+ +

◆ filters

+ +
+
+ + + + +
const lzma_filter* lzma_mt::filters
+
+ +

Encoder only: Filter chain (alternative to a preset)

+

If this is NULL, the preset above is used. Otherwise the preset is ignored and the filter chain specified here is used.

+ +
+
+ +

◆ check

+ +
+
+ + + + +
lzma_check lzma_mt::check
+
+ +

Encoder only: Integrity check type.

+

See check.h for available checks. The xz command line tool defaults to LZMA_CHECK_CRC64, which is a good choice if you are unsure.

+ +
+
+ +

◆ memlimit_threading

+ +
+
+ + + + +
uint64_t lzma_mt::memlimit_threading
+
+ +

Memory usage limit to reduce the number of threads.

+

Encoder: Ignored.

+

Decoder:

+

If the number of threads has been set so high that more than memlimit_threading bytes of memory would be needed, the number of threads will be reduced so that the memory usage will not exceed memlimit_threading bytes. However, if memlimit_threading cannot be met even in single-threaded mode, then decoding will continue in single-threaded mode and memlimit_threading may be exceeded even by a large amount. That is, memlimit_threading will never make lzma_code() return LZMA_MEMLIMIT_ERROR. To truly cap the memory usage, see memlimit_stop below.

+

Setting memlimit_threading to UINT64_MAX or a similar huge value means that liblzma is allowed to keep the whole compressed file and the whole uncompressed file in memory in addition to the memory needed by the decompressor data structures used by each thread! In other words, a reasonable value limit must be set here or it will cause problems sooner or later. If you have no idea what a reasonable value could be, try lzma_physmem() / 4 as a starting point. Setting this limit will never prevent decompression of a file; this will only reduce the number of threads.

+

If memlimit_threading is greater than memlimit_stop, then the value of memlimit_stop will be used for both.

+ +
+
+ +

◆ memlimit_stop

+ +
+
+ + + + +
uint64_t lzma_mt::memlimit_stop
+
+ +

Memory usage limit that should never be exceeded.

+

Encoder: Ignored.

+

Decoder: If decompressing will need more than this amount of memory even in the single-threaded mode, then lzma_code() will return LZMA_MEMLIMIT_ERROR.

Detailed Description

+

Options for BCJ filters.

+

The BCJ filters never change the size of the data. Specifying options for them is optional: if pointer to options is NULL, default value is used. You probably never need to specify options to BCJ filters, so just set the options pointer to NULL and be happy.

+

If options with non-default values have been specified when encoding, the same options must also be specified when decoding.

+
Note
At the moment, none of the BCJ filters support LZMA_SYNC_FLUSH. If LZMA_SYNC_FLUSH is specified, LZMA_OPTIONS_ERROR will be returned. If there is need, partial support for LZMA_SYNC_FLUSH can be added in future. Partial means that flushing would be possible only at offsets that are multiple of 2, 4, or 16 depending on the filter, except x86 which cannot be made to support LZMA_SYNC_FLUSH predictably.

◆ start_offset

+ +
+
+ + + + +
uint32_t lzma_options_bcj::start_offset
+
+ +

Start offset for conversions.

+

This setting is useful only when the same filter is used _separately_ for multiple sections of the same executable file, and the sections contain cross-section branch/call/jump instructions. In that case it is beneficial to set the start offset of the non-first sections so that the relative addresses of the cross-section branch/call/jump instructions will use the same absolute addresses as in the first section.

+

When the pointer to options is NULL, the default value (zero) is used.

Detailed Description

+

Options specific to the LZMA1 and LZMA2 filters.

+

Since LZMA1 and LZMA2 share most of the code, it's simplest to share the options structure too. For encoding, all but the reserved variables need to be initialized unless specifically mentioned otherwise. lzma_lzma_preset() can be used to get a good starting point.

+

For raw decoding, both LZMA1 and LZMA2 need dict_size, preset_dict, and preset_dict_size (if preset_dict != NULL). LZMA1 needs also lc, lp, and pb.

+

Field Documentation

+ +

◆ dict_size

+ +
+
+ + + + +
uint32_t lzma_options_lzma::dict_size
+
+ +

Dictionary size in bytes.

+

Dictionary size indicates how many bytes of the recently processed uncompressed data is kept in memory. One method to reduce size of the uncompressed data is to store distance-length pairs, which indicate what data to repeat from the dictionary buffer. Thus, the bigger the dictionary, the better the compression ratio usually is.

+

Maximum size of the dictionary depends on multiple things:

    +
  • Memory usage limit
    • +
  • Available address space (not a problem on 64-bit systems)
    • +
  • Selected match finder (encoder only)
    • +
+

Currently the maximum dictionary size for encoding is 1.5 GiB (i.e. (UINT32_C(1) << 30) + (UINT32_C(1) << 29)) even on 64-bit systems for certain match finder implementation reasons. In the future, there may be match finders that support bigger dictionaries.

+

Decoder already supports dictionaries up to 4 GiB - 1 B (i.e. UINT32_MAX), so increasing the maximum dictionary size of the encoder won't cause problems for old decoders.

+

Because extremely small dictionaries sizes would have unneeded overhead in the decoder, the minimum dictionary size is 4096 bytes.

+
Note
When decoding, too big dictionary does no other harm than wasting memory.
+ +
+
+ +

◆ preset_dict

+ +
+
+ + + + +
const uint8_t* lzma_options_lzma::preset_dict
+
+ +

Pointer to an initial dictionary.

+

It is possible to initialize the LZ77 history window using a preset dictionary. It is useful when compressing many similar, relatively small chunks of data independently from each other. The preset dictionary should contain typical strings that occur in the files being compressed. The most probable strings should be near the end of the preset dictionary.

+

This feature should be used only in special situations. For now, it works correctly only with raw encoding and decoding. Currently none of the container formats supported by liblzma allow preset dictionary when decoding, thus if you create a .xz or .lzma file with preset dictionary, it cannot be decoded with the regular decoder functions. In the future, the .xz format will likely get support for preset dictionary though.

+ +
+
+ +

◆ preset_dict_size

+ +
+
+ + + + +
uint32_t lzma_options_lzma::preset_dict_size
+
+ +

Size of the preset dictionary.

+

Specifies the size of the preset dictionary. If the size is bigger than dict_size, only the last dict_size bytes are processed.

+

This variable is read only when preset_dict is not NULL. If preset_dict is not NULL but preset_dict_size is zero, no preset dictionary is used (identical to only setting preset_dict to NULL).

+ +
+
+ +

◆ lc

+ +
+
+ + + + +
uint32_t lzma_options_lzma::lc
+
+ +

Number of literal context bits.

+

How many of the highest bits of the previous uncompressed eight-bit byte (also known as `literal') are taken into account when predicting the bits of the next literal.

+

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 uncompressed data.

+

There is a limit that applies to literal context bits and literal position bits together: lc + lp <= 4. Without this limit the decoding could become very slow, which could have security related results in some cases like email servers doing virus scanning. This limit also simplifies the internal implementation in liblzma.

+

There may be LZMA1 streams that have lc + lp > 4 (maximum possible lc would be 8). It is not possible to decode such streams with liblzma.

+ +
+
+ +

◆ lp

+ +
+
+ + + + +
uint32_t lzma_options_lzma::lp
+
+ +

Number of literal position bits.

+

lp affects what kind of alignment in the uncompressed data is assumed when encoding literals. A literal is a single 8-bit byte. See pb below for more information about alignment.

+ +
+
+ +

◆ pb

+ +
+
+ + + + +
uint32_t lzma_options_lzma::pb
+
+ +

Number of position bits.

+

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 alignment is known, setting pb accordingly may reduce the file size a little. E.g. with text files having 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 compressed with LZMA1 or LZMA2.

+ +
+
+ +

◆ mode

+ +
+
+ + + + +
lzma_mode lzma_options_lzma::mode
+
+

Compression mode

+ +
+
+ +

◆ nice_len

+ +
+
+ + + + +
uint32_t lzma_options_lzma::nice_len
+
+ +

Nice length of a match.

+

This determines how many bytes the encoder compares from the match candidates when looking for the best match. Once a match of at least nice_len bytes long is found, the encoder stops looking for better candidates and encodes the match. (Naturally, if the found match is actually longer than nice_len, the actual length is encoded; it's not truncated to nice_len.)

+

Bigger values usually increase the compression ratio and compression time. For most files, 32 to 128 is a good value, which gives very good compression ratio at good speed.

+

The exact minimum value depends on the match finder. The maximum is 273, which is the maximum length of a match that LZMA1 and LZMA2 can encode.

+ +
+
+ +

◆ mf

+ +
+
+ + + + +
lzma_match_finder lzma_options_lzma::mf
+
+

Match finder ID

+ +
+
+ +

◆ depth

+ +
+
+ + + + +
uint32_t lzma_options_lzma::depth
+
+ +

Maximum search depth in the match finder.

+

For every input byte, match finder searches through the hash chain or binary tree in a loop, each iteration going one step deeper in the chain or tree. The searching stops if

    +
  • a match of at least nice_len bytes long is found;
    • +
  • all match candidates from the hash chain or binary tree have been checked; or
    • +
  • maximum search depth is reached.
    • +
+

Maximum search depth is needed to prevent the match finder from wasting too much time in case there are lots of short match candidates. On the other hand, stopping the search before all candidates have been checked can reduce compression ratio.

+

Setting depth to zero tells liblzma to use an automatic default value, that depends on the selected match finder and nice_len. The default is in the range [4, 200] or so (it may vary between liblzma versions).

+

Using a bigger depth value than the default can increase compression ratio in some cases. There is no strict maximum value, but high values (thousands or millions) should be used with care: the encoder could remain fast enough with typical input, but malicious input could cause the match finder to slow down dramatically, possibly creating a denial of service attack.

+ +
+
+ +

◆ ext_flags

+ +
+
+ + + + +
uint32_t lzma_options_lzma::ext_flags
+
+ +

For LZMA_FILTER_LZMA1EXT: Extended flags.

+

This is used only with LZMA_FILTER_LZMA1EXT.

+

Currently only one flag is supported, LZMA_LZMA1EXT_ALLOW_EOPM:

+
    +
  • Encoder: If the flag is set, then end marker is written just like it is with LZMA_FILTER_LZMA1. Without this flag the end marker isn't written and the application has to store the uncompressed size somewhere outside the compressed stream. To decompress streams without the end marker, the application has to set the correct uncompressed size in ext_size_low and ext_size_high.
    • +

  • Decoder: If the uncompressed size in ext_size_low and ext_size_high is set to the special value UINT64_MAX (indicating unknown uncompressed size) then this flag is ignored and the end marker must always be present, that is, the behavior is identical to LZMA_FILTER_LZMA1.

    +

    Otherwise, if this flag isn't set, then the input stream must not have the end marker; if the end marker is detected then it will result in LZMA_DATA_ERROR. This is useful when it is known that the stream must not have the end marker and strict validation is wanted.

    +

    If this flag is set, then it is autodetected if the end marker is present after the specified number of uncompressed bytes has been decompressed (ext_size_low and ext_size_high). The end marker isn't allowed in any other position. This behavior is useful when uncompressed size is known but the end marker may or may not be present. This is the case, for example, in .7z files (valid .7z files that have the end marker in LZMA1 streams are rare but they do exist).

    +
    • +
+ +
+
+ +

◆ ext_size_low

+ +
+
+ + + + +
uint32_t lzma_options_lzma::ext_size_low
+
+ +

For LZMA_FILTER_LZMA1EXT: Uncompressed size (low bits)

+

The 64-bit uncompressed size is needed for decompression with LZMA_FILTER_LZMA1EXT. The size is ignored by the encoder.

+

The special value UINT64_MAX indicates that the uncompressed size is unknown and that the end of payload marker (also known as end of stream marker) must be present to indicate the end of the LZMA1 stream. Any other value indicates the expected uncompressed size of the LZMA1 stream. (If LZMA1 was used together with filters that change the size of the data then the uncompressed size of the LZMA1 stream could be different than the final uncompressed size of the filtered stream.)

+

ext_size_low holds the least significant 32 bits of the uncompressed size. The most significant 32 bits must be set in ext_size_high. The macro lzma_ext_size_set(opt_lzma, u64size) can be used to set these members.

+

The 64-bit uncompressed size is split into two uint32_t variables because there were no reserved uint64_t members and using the same options structure for LZMA_FILTER_LZMA1, LZMA_FILTER_LZMA1EXT, and LZMA_FILTER_LZMA2 was otherwise more convenient than having a new options structure for LZMA_FILTER_LZMA1EXT. (Replacing two uint32_t members with one uint64_t changes the ABI on some systems as the alignment of this struct can increase from 4 bytes to 8.)

+ +
+
+ +

◆ ext_size_high

+ +
+
+ + + + +
uint32_t lzma_options_lzma::ext_size_high
+
+ +

For LZMA_FILTER_LZMA1EXT: Uncompressed size (high bits)

+

This holds the most significant 32 bits of the uncompressed size.

Detailed Description

+

Passing data to and from liblzma.

+

The lzma_stream structure is used for

    +
  • passing pointers to input and output buffers to liblzma;
    • +
  • defining custom memory handler functions; and
    • +
  • holding a pointer to coder-specific internal data structures.
    • +
+

Typical usage:

+
    +
  • After allocating lzma_stream (on stack or with malloc()), it must be initialized to LZMA_STREAM_INIT (see LZMA_STREAM_INIT for details).
    • +
  • Initialize a coder to the lzma_stream, for example by using lzma_easy_encoder() or lzma_auto_decoder(). Some notes:
      +
    • In contrast to zlib, strm->next_in and strm->next_out are ignored by all initialization functions, thus it is safe to not initialize them yet.
      • +
    • The initialization functions always set strm->total_in and strm->total_out to zero.
      • +
    • If the initialization function fails, no memory is left allocated that would require freeing with lzma_end() even if some memory was associated with the lzma_stream structure when the initialization function was called.
      • +
    +
    • +
  • Use lzma_code() to do the actual work.
    • +
  • Once the coding has been finished, the existing lzma_stream can be reused. It is OK to reuse lzma_stream with different initialization function without calling lzma_end() first. Old allocations are automatically freed.
    • +
  • Finally, use lzma_end() to free the allocated memory. lzma_end() never frees the lzma_stream structure itself.
    • +
+

Application may modify the values of total_in and total_out as it wants. They are updated by liblzma to match the amount of data read and written but aren't used for anything else except as a possible return values from lzma_get_progress().

For now, version must always be zero. With non-zero version, the lzma_stream_header_encode() and lzma_stream_footer_encode() will return LZMA_OPTIONS_ERROR.

+

lzma_stream_header_decode() and lzma_stream_footer_decode() will always set this to the lowest value that supports all the features indicated by the Stream Flags field. The application must check that the version number set by the decoding functions is supported by the application. Otherwise it is possible that the application will decode the Stream incorrectly.

+ +
+
+ +

◆ backward_size

+ +
+
+ + + + +
lzma_vli lzma_stream_flags::backward_size
+
+ +

Backward Size.

+

Backward Size must be a multiple of four bytes. In this Stream format version, Backward Size is the size of the Index field.

+

Backward Size isn't actually part of the Stream Flags field, but it is convenient to include in this structure anyway. Backward Size is present only in the Stream Footer. There is no need to initialize backward_size when encoding Stream Header.

+

lzma_stream_header_decode() always sets backward_size to LZMA_VLI_UNKNOWN so that it is convenient to use lzma_stream_flags_compare() when both Stream Header and Stream Footer have been decoded.

+ +
+
+ +

◆ check

+ +
+
+ + + + +
lzma_check lzma_stream_flags::check
+
+ +

Check ID.

+

This indicates the type of the integrity check calculated from uncompressed data.

◆ LZMA_VERSION_STABILITY

+ +
+
+ + + + +
#define LZMA_VERSION_STABILITY   LZMA_VERSION_STABILITY_STABLE
+
+ +

Version stability marker.

+

This will always be one of three values:

    +
  • LZMA_VERSION_STABILITY_ALPHA
    • +
  • LZMA_VERSION_STABILITY_BETA
    • +
  • LZMA_VERSION_STABILITY_STABLE
    • +

+
+ +

◆ LZMA_VERSION

+ +
+
+ + + + +
#define LZMA_VERSION
+
+Value:
(LZMA_VERSION_MAJOR * UINT32_C(10000000) \
+
+ LZMA_VERSION_MINOR * UINT32_C(10000) \
+
+ LZMA_VERSION_PATCH * UINT32_C(10) \
+
+ LZMA_VERSION_STABILITY)
+
+

Compile-time version number.

+

The version number is of format xyyyzzzs where

    +
  • x = major
    • +
  • yyy = minor
    • +
  • zzz = revision
    • +
  • s indicates stability: 0 = alpha, 1 = beta, 2 = stable
    • +
+

The same xyyyzzz triplet is never reused with different stability levels. For example, if 5.1.0alpha has been released, there will never be 5.1.0beta or 5.1.0 stable.

+
Note
The version number of liblzma has nothing to with the version number of Igor Pavlov's LZMA SDK.
+ +
+
+ +

◆ LZMA_VERSION_STRING

+ +
+
+ + + + +
#define LZMA_VERSION_STRING

+
LZMA_VERSION_PATCH, LZMA_VERSION_STABILITY_STRING, \
+
LZMA_VERSION_COMMIT)
+
+

Compile-time version as a string.

+

This can be for example "4.999.5alpha", "4.999.8beta", or "5.0.0" (stable versions don't have any "stable" suffix). In future, a snapshot built from source code repository may include an additional suffix, for example "4.999.8beta-21-g1d92". The commit ID won't be available in numeric form in LZMA_VERSION macro.

Detailed Description

+

Variable-length integer handling.

+
Note
Never include this file directly. Use <lzma.h> instead.
+

In the .xz format, most integers are encoded in a variable-length representation, which is sometimes called little endian base-128 encoding. This saves space when smaller values are more likely than bigger values.

+

The encoding scheme encodes seven bits to every byte, using minimum number of bytes required to represent the given value. Encodings that use non-minimum number of bytes are invalid, thus every integer has exactly one encoded representation. The maximum number of bits in a VLI is 63, thus the vli argument must be less than or equal to UINT64_MAX / 2. You should use LZMA_VLI_MAX for clarity.

+

◆ lzma_vli_is_valid

+ +
+
+ + + + + + + + +
#define lzma_vli_is_valid( vli)    ((vli) <= LZMA_VLI_MAX || (vli) == LZMA_VLI_UNKNOWN)
+
+ +

Validate a variable-length integer.

+

This is useful to test that application has given acceptable values for example in the uncompressed_size and compressed_size variables.

+
Returns
True if the integer is representable as VLI or if it indicates unknown value. False if the integer cannot be represented as VLI.
+ +
+
+

Typedef Documentation

+ +

◆ lzma_vli

+ +
+
+ + + + +
typedef uint64_t lzma_vli
+
+ +

Variable-length integer type.

+

Valid VLI values are in the range [0, LZMA_VLI_MAX]. Unknown value is indicated with LZMA_VLI_UNKNOWN, which is the maximum value of the underlying integer type.

+

lzma_vli will be uint64_t for the foreseeable future. If a bigger size is needed in the future, it is guaranteed that 2 * LZMA_VLI_MAX will not overflow lzma_vli. This simplifies integer overflow detection.

+ +
+
+

Function Documentation

+ +

◆ lzma_vli_encode()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
lzma_ret lzma_vli_encode (lzma_vli vli,
size_t * vli_pos,
uint8_t * out,
size_t * out_pos,
size_t out_size 
)
+
+ +

Encode a variable-length integer.

+

This function has two modes: single-call and multi-call. Single-call mode encodes the whole integer at once; it is an error if the output buffer is too small. Multi-call mode saves the position in *vli_pos, and thus it is possible to continue encoding if the buffer becomes full before the whole integer has been encoded.

+
Parameters
+ + + + + + +
vliInteger to be encoded
[out]vli_posHow many VLI-encoded bytes have already been written out. When starting to encode a new integer in multi-call mode, *vli_pos must be set to zero. To use single-call encoding, set vli_pos to NULL.
[out]outBeginning of the output buffer
[out]out_posThe next byte will be written to out[*out_pos].
out_sizeSize of the out buffer; the first byte into which no data is written to is out[out_size].
+
+
+
Returns
Slightly different return values are used in multi-call and single-call modes.
+

Single-call (vli_pos == NULL):

    +
  • LZMA_OK: Integer successfully encoded.
    • +
  • LZMA_PROG_ERROR: Arguments are not sane. This can be due to too little output space; single-call mode doesn't use LZMA_BUF_ERROR, since the application should have checked the encoded size with lzma_vli_size().
    • +
+

Multi-call (vli_pos != NULL):

    +
  • LZMA_OK: So far all OK, but the integer is not completely written out yet.
    • +
  • LZMA_STREAM_END: Integer successfully encoded.
    • +
  • LZMA_BUF_ERROR: No output space was provided.
    • +
  • LZMA_PROG_ERROR: Arguments are not sane.
    • +
+ +
+
+ +

◆ lzma_vli_decode()

+ +
+
+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
lzma_ret lzma_vli_decode (lzma_vli * vli,
size_t * vli_pos,
const uint8_t * in,
size_t * in_pos,
size_t in_size 
)
+
+ +

Decode a variable-length integer.

+

Like lzma_vli_encode(), this function has single-call and multi-call modes.

+
Parameters
+ + + + + + +
[out]vliPointer to decoded integer. The decoder will initialize it to zero when *vli_pos == 0, so application isn't required to initialize *vli.
[out]vli_posHow many bytes have already been decoded. When starting to decode a new integer in multi-call mode, *vli_pos must be initialized to zero. To use single-call decoding, set vli_pos to NULL.
inBeginning of the input buffer
[out]in_posThe next byte will be read from in[*in_pos].
in_sizeSize of the input buffer; the first byte that won't be read is in[in_size].
+
+
+
Returns
Slightly different return values are used in multi-call and single-call modes.
+

Single-call (vli_pos == NULL):

    +
  • LZMA_OK: Integer successfully decoded.
    • +
  • LZMA_DATA_ERROR: Integer is corrupt. This includes hitting the end of the input buffer before the whole integer was decoded; providing no input at all will use LZMA_DATA_ERROR.
    • +
  • LZMA_PROG_ERROR: Arguments are not sane.
    • +
+

Multi-call (vli_pos != NULL):

    +
  • LZMA_OK: So far all OK, but the integer is not completely decoded yet.
    • +
  • LZMA_STREAM_END: Integer successfully decoded.
    • +
  • LZMA_DATA_ERROR: Integer is corrupt.
    • +
  • LZMA_BUF_ERROR: No input was provided.
    • +
  • LZMA_PROG_ERROR: Arguments are not sane.
    • +
+ +
+
+ +

◆ lzma_vli_size()

+ +
+
+ + + + + + + + +
uint32_t lzma_vli_size (lzma_vli vli)
+
+ +

Get the number of bytes required to encode a VLI.

+
Parameters
+ + +
vliInteger whose encoded size is to be determined
+
+
+
Returns
Number of bytes on success (1-9). If vli isn't valid, zero is returned.

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. + + +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: How is multi-threaded compression implemented in XZ Utils? + +A: The simplest method is splitting the uncompressed data into blocks + and compressing them in parallel independent from each other. + This is currently the only threading method supported in XZ Utils. + 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. + + 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. + + At least two other threading methods are possible but these haven't + been implemented in XZ Utils: + + Match finder parallelization 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. + For example, combining match finder parallelization with pigz-style + threading or independent-blocks-threading can cut the memory usage + by 50 %. + + +Q: I told xz to use many threads but it is using only one or two + processor cores. What is wrong? + +A: Since multi-threaded compression is done by splitting the data into + blocks that are compressed individually, if the input file is too + small for the block size, then many threads cannot be used. The + default block size increases when the compression level is + increased. For example, xz -6 uses 8 MiB LZMA2 dictionary and + 24 MiB blocks, and xz -9 uses 64 MiB LZMA dictionary and 192 MiB + blocks. If the input file is 100 MiB, xz -6 can use five threads + of which one will finish quickly as it has only 4 MiB to compress. + However, for the same file, xz -9 can only use one thread. + + One can adjust block size with --block-size=SIZE but making the + block size smaller than LZMA2 dictionary is waste of RAM: using + xz -9 with 6 MiB blocks isn't any better than using xz -6 with + 6 MiB blocks. The default settings use a block size bigger than + the LZMA2 dictionary size because this was seen as a reasonable + compromise between RAM usage and compression ratio. + + When decompressing, the ability to use threads depends on how the + file was created. If it was created in multi-threaded mode then + it can be decompressed in multi-threaded mode too if there are + multiple blocks in the file. + + +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. It is + a separate project, which provides a limited but significantly + smaller XZ decoder implementation than XZ Utils.

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 0000000..4865def --- /dev/null +++ b/doc/lzma-file-format.txt @@ -0,0 +1,173 @@ + +The .lzma File Format +===================== + + 0.

In contrast, the command line tool from XZ Utils + considers the .lzma file to be corrupt if there is data after + the first .lzma stream. + + +1.1.

Properties + + The Properties field contains three properties. An abbreviation + is given in parentheses, followed by the value range of the + property. The field consists of + + 1) the number of literal context bits (lc, [0, 8]); + 2) the number of literal position bits (lp, [0, 4]); and + 3) the number of position bits (pb, [0, 4]). + + The properties are encoded using the following formula: + + Properties = (pb * 5 + lp) * 9 + lc + + The following C code illustrates a straightforward way to + decode the Properties field: + + uint8_t lc, lp, pb; + uint8_t prop = get_lzma_properties(); + if (prop > (4 * 5 + 4) * 9 + 8) + return LZMA_PROPERTIES_ERROR; + + pb = prop / (9 * 5); + prop -= pb * 9 * 5; + lp = prop / 9; + lc = prop - lp * 9; + + XZ Utils has an additional requirement: lc + lp <= 4. Files + which don't follow this requirement cannot be decompressed + with XZ Utils. Usually this isn't a problem since the most + common lc/lp/pb values are 3/0/2. It is the only lc/lp/pb + combination that the files created by LZMA Utils can have, + but LZMA Utils can decompress files with any lc/lp/pb. + + +1.1.2. Dictionary Size + + Dictionary Size is stored as an unsigned 32-bit little endian + integer. Any 32-bit value is possible, but for maximum + portability, only sizes of 2^n and 2^n + 2^(n-1) should be + used. + + LZMA Utils creates only files with dictionary size 2^n, + 16 <= n <= 25. LZMA Utils can decompress files with any + dictionary size. + + XZ Utils creates and decompresses .lzma files only with + dictionary sizes 2^n and 2^n + 2^(n-1). If some other + dictionary size is specified when compressing, the value + stored in the Dictionary Size field is a rounded up, but the + specified value is still used in the actual compression code. + + +1.1.3. Uncompressed Size + + Uncompressed Size is stored as unsigned 64-bit little endian + integer. A special value of 0xFFFF_FFFF_FFFF_FFFF indicates + that Uncompressed Size is unknown. End of Payload Marker (*) + is used if Uncompressed Size is unknown. End of Payload Marker + is allowed but rarely used if Uncompressed Size is known. + XZ Utils 5.2.5 and older don't support .lzma files that have + End of Payload Marker together with a known Uncompressed Size. + + XZ Utils rejects files whose Uncompressed Size field specifies + a known size that is 256 GiB or more. This is to reject false + positives when trying to guess if the input file is in the + .lzma format. When Uncompressed Size is unknown, there is no + limit for the uncompressed size of the file. + + (*) Some tools use the term End of Stream (EOS) marker + instead of End of Payload Marker. + + +1.2.

The native file format is the .xz + format, but the legacy .lzma format used by LZMA Utils and raw com- + pressed streams with no container format headers are also supported. + In addition, decompression of the .lz format used by lzip is supported. + + xz compresses or decompresses each file according to the selected oper- + ation mode. If no files are given or file is -, xz reads from standard + input and writes the processed data to standard output. xz will refuse + (display an error and skip the file) to write compressed data to stan- + dard output if it is a terminal. Similarly, xz will refuse to read + compressed data from standard input if it is a terminal. + + Unless --stdout is specified, files other than - are written to a new + file whose name is derived from the source file name: + + o When compressing, the suffix of the target file format (.xz or + .lzma) is appended to the source filename to get the target file- + name. + + o When decompressing, the .xz, .lzma, or .lz suffix is removed from + the filename to get the target filename. xz also recognizes the + suffixes .txz and .tlz, and replaces them with the .tar suffix. + + If the target file already exists, an error is displayed and the file + is skipped. + + Unless writing to standard output, xz will display a warning and skip + the file if any of the following applies: + + o File is not a regular file. Symbolic links are not followed, and + thus they are not considered to be regular files. + + o File has more than one hard link. + + o File has setuid, setgid, or sticky bit set. + + o The operation mode is set to compress and the file already has a + suffix of the target file format (.xz or .txz when compressing to + the .xz format, and .lzma or .tlz when compressing to the .lzma for- + mat). + + o The operation mode is set to decompress and the file doesn't have a + suffix of any of the supported file formats (.xz, .txz, .lzma, .tlz, + or .lz). + + After successfully compressing or decompressing the file, xz copies the + owner, group, permissions, access time, and modification time from the + source file to the target file. If copying the group fails, the per- + missions are modified so that the target file doesn't become accessible + to users who didn't have permission to access the source file. xz + doesn't support copying other metadata like access control lists or ex- + tended attributes yet. + + Once the target file has been successfully closed, the source file is + removed unless --keep was specified. The source file is never removed + if the output is written to standard output or if an error occurs. + + Sending SIGINFO or SIGUSR1 to the xz process makes it print progress + information to standard error. This has only limited use since when + standard error is a terminal, using --verbose will display an automati- + cally updating progress indicator. + + Memory usage + The memory usage of 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 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 (for exam- + ple, 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, for example, + 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, for example, 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 af- + ter 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, + for example, 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 ef- + fect. + + -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, for exam- + ple, less -S may be convenient if the terminal isn't wide + enough. + + The exact output may vary between xz versions and different lo- + cales. For machine-readable output, --robot --list should be + used. + + Operation modifiers + -k, --keep + Don't delete the input files. + + Since xz 5.2.6, this option also makes xz 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. In earlier versions this was only done with + --force. + + -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 in- + stead 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 de- + compressed 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 in- + stead 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 ad- + dition to files with the .xz, .txz, .lzma, .tlz, or .lz 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 be- + fore 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. + + lzip Accept only .lz files when decompressing. Compression is + not supported. + + The .lz format version 0 and the unextended version 1 are + supported. Version 0 files were produced by lzip 1.3 and + older. Such files aren't common but may be found from + file archives as a few source packages were released in + this format. People might have old personal files in + this format too. Decompression support for the format + version 0 was removed in lzip 1.18. + + lzip 1.4 and later create files in the format version 1. + The sync flush marker extension to the format version 1 + was added in lzip 1.6. This extension is rarely used and + isn't supported by xz (diagnosed as corrupt input). + + 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 de- + compressing. 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 us- + ing a too high preset level might make it painful to decompress + 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 for distributing + 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 us- + age 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 ra- + tio, but with bad luck this can also make it worse. Decompres- + sor 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 al- + located in each thread for buffering input and output. The de- + fault 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 (ei- + ther the default value in threaded mode or the value specified + with --block-size=size), the encoder will create additional + blocks while keeping the boundaries specified in sizes. For ex- + ample, 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 attempt to + adjust the settings downwards so that the limit is no longer ex- + ceeded and display a notice that automatic adjustment was done. + The adjustments are done in this order: reducing the number of + threads, switching to single-threaded mode if even one thread in + multi-threaded mode exceeds the limit, and finally reducing the + LZMA2 dictionary size. + + When compressing with --format=raw or if --no-adjust has been + specified, only the number of threads may be reduced since it + can be done without affecting the compressed output. + + If the limit cannot be met even with the adjustments described + above, 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). + + For 32-bit xz there is a special case: if the limit would be + over 4020 MiB, the limit is set to 4020 MiB. On MIPS32 2000 MiB + is used instead. (The values 0 and max aren't affected by this. + A similar feature doesn't exist for decompression.) This can be + helpful when a 32-bit executable has access to 4 GiB address + space (2 GiB on MIPS32) while hopefully doing no harm in other + situations. + + 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 ex- + ceeding the limit, xz will display an error and decompressing + the file will fail. See --memlimit-compress=limit for possible + ways to specify the limit. + + --memlimit-mt-decompress=limit + Set a memory usage limit for multi-threaded decompression. This + can only affect the number of threads; this will never make xz + refuse to decompress a file. If limit is too low to allow any + multi-threading, the limit is ignored and xz will continue in + single-threaded mode. Note that if also --memlimit-decompress + is used, it will always apply to both single-threaded and multi- + threaded modes, and so the effective limit for multi-threading + will never be higher than the limit set with --memlimit-decom- + press. + + In contrast to the other memory usage limit options, --mem- + limit-mt-decompress=limit has a system-specific default limit. + xz --info-memory can be used to see the current value. + + This option and its default value exist because without any + limit the threaded decompressor could end up allocating an in- + sane amount of memory with some input files. If the default + limit is too low on your system, feel free to increase the limit + but never set it to a value larger than the amount of usable RAM + as with appropriate input files xz will attempt to use that + amount of memory even with a low number of threads. Running out + of memory or swapping will not improve decompression perfor- + mance. + + See --memlimit-compress=limit for possible ways to specify the + limit. Setting limit to 0 resets the limit to the default sys- + tem-specific value. + + -M limit, --memlimit=limit, --memory=limit + This is equivalent to specifying --memlimit-compress=limit + --memlimit-decompress=limit --memlimit-mt-decompress=limit. + + --no-adjust + Display an error and exit if the memory usage limit cannot be + met without adjusting settings that affect the compressed out- + put. That is, this prevents xz from switching the encoder from + multi-threaded mode to single-threaded mode and from reducing + the LZMA2 dictionary size. Even when this option is used the + number of threads may be reduced to meet the memory usage limit + as that won't affect the compressed output. + + Automatic adjusting is always disabled when creating raw streams + (--format=raw). + + -T threads, --threads=threads + Specify the number of worker threads to use. Setting threads to + a special value 0 makes xz use up to as many threads as the pro- + cessor(s) on the system support. The actual number of threads + can be fewer 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. + + The single-threaded and multi-threaded compressors produce dif- + ferent output. Single-threaded compressor will give the small- + est file size but only the output from the multi-threaded com- + pressor can be decompressed using multiple threads. Setting + threads to 1 will use the single-threaded mode. Setting threads + to any other value, including 0, will use the multi-threaded + compressor even if the system supports only one hardware thread. + (xz 5.2.x used single-threaded mode in this situation.) + + To use multi-threaded mode with only one thread, set threads to + +1. The + prefix has no effect with values other than 1. A + memory usage limit can still make xz switch to single-threaded + mode unless --no-adjust is used. Support for the + prefix was + added in xz 5.4.0. + + If an automatic number of threads has been requested and no mem- + ory usage limit has been specified, then a system-specific de- + fault soft limit will be used to possibly limit the number of + threads. It is a soft limit in sense that it is ignored if the + number of threads becomes one, thus a soft limit will never stop + xz from compressing or decompressing. This default soft limit + will not make xz switch from multi-threaded mode to single- + threaded mode. The active limits can be seen with xz + --info-memory. + + Currently the only threading method is to split the input into + blocks and compress them independently from each other. The de- + fault block size depends on the compression level and can be + overridden with the --block-size=size option. + + Threaded decompression only works on files that contain multiple + blocks with size information in block headers. All large enough + files compressed in multi-threaded mode meet this condition, but + files compressed in single-threaded mode don't even if + --block-size=size has been used. + + Custom compressor filter chains + A custom filter chain allows specifying the compression settings in de- + tail 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 op- + tion 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. De- + pending on the filter, this limitation is either inherent to the filter + 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 is- + sues 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 --ex- + treme. 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 se- + quences (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. For example, in typical English text, an + upper-case letter is often followed by a lower-case let- + ter, and a lower-case letter is usually followed by an- + other 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 + uncompressed 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 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 alignment is known, setting pb accordingly may + reduce the file size a little. For example, with text + files having 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 de- + fault 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 in- + terrupt 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] + --arm[=options] + --armthumb[=options] + --arm64[=options] + --powerpc[=options] + --ia64[=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 re- + versible, 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. The BCJ filters are very fast and use an in- + significant amount of memory. + + These BCJ filters have known problems related to the compression + ratio: + + o Some types of files containing executable code (for example, + 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 conver- + sion, which will make the compression worse with these files. + + o If a BCJ filter is applied on an archive, it is possible that + it makes the compression ratio worse than not using a BCJ + filter. For example, if there are similar or even identical + executables then filtering will likely make the files less + similar and thus compression is worse. The contents of non- + executable files in the same archive can matter too. In + practice one has to try with and without a BCJ filter to see + which is better in each situation. + + Different instruction sets have different alignment: the exe- + cutable file must be aligned to a multiple of this value in the + input data to make the filter work. + + Filter Alignment Notes + x86 1 32-bit or 64-bit x86 + ARM 4 + ARM-Thumb 2 + ARM64 4 4096-byte alignment is best + PowerPC 4 Big endian only + IA-64 16 Itanium + SPARC 4 + + Since the BCJ-filtered data is usually compressed with LZMA2, + the compression ratio may be improved slightly if the LZMA2 op- + tions are set to match the alignment of the selected BCJ filter. + For example, with the IA-64 filter, it's good to set pb=4 or + even pb=4,lp=4,lc=0 with LZMA2 (2^4=16). The x86 filter is an + exception; it's usually 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 be- + tween 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 de- + fault 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, for example, uncompressed + bitmap images or uncompressed PCM audio. However, special pur- + pose algorithms may give significantly better results than Delta + + LZMA2. This is true especially with audio, which compresses + faster and better, for example, 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, + for example, 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, for example, due to user interruption, also the comple- + tion percentage 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 li- + blzma, which may be the case with various scripts. The output + with this option enabled is meant to be stable across xz re- + leases. See the section ROBOT MODE for details. + + --info-memory + Display, in human-readable format, how much physical memory + (RAM) and how many processor threads 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 op- + tions, 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. It + will be supported for compression and decompression in the future. + + Version + xz --robot --version prints the version number of xz and liblzma in the + following format: + + XZ_VERSION=XYYYZZZS + LIBLZMA_VERSION=XYYYZZZS + + X Major version. + + YYY Minor version. 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.

Total amount of physical memory (RAM) in bytes. + + 2.

Excluding shell initialization scripts and + similar special cases, scripts must never set or unset XZ_DE- + FAULTS. + + 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 + when xz is run by a script or tool, for example, GNU tar(1): + + XZ_OPT=-2v tar caf foo.tar.xz foo + + Scripts may use XZ_OPT, for example, to set script-specific de- + fault compression options.

For example, 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, un- + lzma, 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 existing + scripts. There are some incompatibilities though, which may sometimes + 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 un- + compressed 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 ac- + cepts 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 ob- + scure 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 the default -6, but needs less memory for compression and decom- + pression (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.

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 (for example, + 32 MiB) to compress well, but you want to compress it quicker than xz + -8 would do, a preset with a low CompCPU value (for example, 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. Re- + member that using a dictionary bigger than the size of the uncompressed + 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, for example, 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. For example, + 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. For example, 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, for example, as un- + compressed TIFF. The distance parameter of the Delta filter is set to + match the number of bytes per pixel in the image. For example, 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 (for example, + .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 2023-07-17 XZ(1) diff --git a/doc/man/txt/xzdec.txt b/doc/man/txt/xzdec.txt new file mode 100644 index 0000000..a914e20 --- /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 lz- + madec 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 in- + termediate progress information: sending SIGINFO to xzdec does nothing, + 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 + + +==============+=================+===============+=======+ + | Block Header | Compressed Data | Block Padding | Check | + +==============+=================+===============+=======+ + + +3.1. Block Header + + +-------------------+-------------+=================+ + | Block Header Size | Block Flags | Compressed Size | + +-------------------+-------------+=================+ + + +===================+======================+ + ---> | Uncompressed Size | List of Filter Flags | + +===================+======================+ + + +================+--+--+--+--+ + ---> | Header Padding | CRC32 | + +================+--+--+--+--+ + + +3.1.1. 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. The smallest dictionary size is 4 KiB and the biggest + is 4 GiB. + + Raw value Mantissa Exponent Dictionary size + 0 2 11 4 KiB + 1 3 11 6 KiB + 2 2 12 8 KiB + 3 3 12 12 KiB + 4 2 13 16 KiB + 5 3 13 24 KiB + 6 2 14 32 KiB + ... ... ... ... + 35 3 27 768 MiB + 36 2 28 1024 MiB + 37 3 29 1536 MiB + 38 2 30 2048 MiB + 39 3 30 3072 MiB + 40 2 31 4096 MiB - 1 B + + Instead of having a table in the decoder, the dictionary size + can be decoded using the following C code: + + const uint8_t bits = get_dictionary_flags() & 0x3F; + if (bits > 40) + return DICTIONARY_TOO_BIG; // Bigger than 4 GiB + + uint32_t dictionary_size; + if (bits == 40) { + dictionary_size = UINT32_MAX; + } else { + dictionary_size = 2 | (bits & 1); + dictionary_size <<= bits / 2 + 11; + } + + +5.3.2. 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 filter [1] + 0x08 2 bytes ARM Thumb filter [1] + 0x09 4 bytes SPARC filter + 0x0A 4 bytes ARM64 filter [2] + + [1] These are for little endian instruction encoding. + This must not be confused with data endianness. + A processor configured for big endian data access + may still use little endian instruction encoding. + The filters don't care about the data endianness. + + [2] 4096-byte alignment gives the best results + because the address in the ADRP instruction + is a multiple of 4096 bytes. + + If the size of Filter Properties is four bytes, the Filter + Properties field contains the start offset used for address + conversions.
