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

The -repository was checked out to an ext4 filesystem on M.2 SSD. - -Three functionally equivalent tools for computing git status were benchmarked: - -* `gitstatusd` -* `git` with `core.untrackedcache` enabled and `core.fsmonitor` disabled -* `lg2` -- a demo/example executable from [libgit2](https://github.com/romkatv/libgit2) that - implements a subset of `git` functionality on top of libgit2 API; for the purposes of this - benchmark the subset is sufficient to generate the same data as the other tools - -Every tool was benchmark in cold and hot conditions. For `git` the first run in a repository was -considered cold, with the following runs considered hot. `lg2` was patched to compute results twice -in a single invocation without freeing the repository in between; the second run was considered hot. -The same patching was not done for `git` because `git` cannot be easily modified to refresh inmemory -index state between invocations; in fact, this limitation is one of the primary reasons developers -use libgit2. `gitstatusd` was benchmarked similarly to `lg2` with two result computations in the -same invocation. - -Two commands were benchmarked: `status` and `describe`. - -### Status - -In this benchmark all tools were computing the equivalent of `git status`. Lower numbers are better. - -| Tool | Cold | Hot | -|---------------|-----------:|------------:| -| **gitstatus** | **291 ms** | **30.9 ms** | -| git | 876 ms | 295 ms | -| lg2 | 1730 ms | 1310 ms | - -gitstatusd is substantially faster than the alternatives, especially on hot runs. Note that hot runs -are of primary importance to the main use case of gitstatus in interactive shells. - -The performance of `git status` fluctuated wildly in this benchmarks for reasons unknown to the -author. Moreover, performance is sticky -- once `git status` settles around a number, it stays -there for a long time. Numbers as diverse as 295, 352, 663 and 730 had been observed on hot runs on -the same repository. The number in the table is the lowest (fastest or best) that `git status` had -shown. - -### Describe - -In this benchmark all tools were computing the equivalent of `git describe --tags --exact-match` -to find tags that resolve to the same commit as `HEAD`. Lower numbers are better. - -| Tool | Cold | Hot | -|---------------|------------:|--------------:| -| **gitstatus** | **4.04 ms** | **0.0345 ms** | -| git | 18.0 ms | 14.5 ms | -| lg2 | 185 ms | 45.2 ms | - -gitstatusd is once again faster than the alternatives, more so on hot runs. - -## Why fast - -Since gitstatusd doesn't have to print all staged/unstaged/untracked files but only report -whether there are any, it can terminate repository scan early. It can also remember which files -were dirty on the previous run and check them first on the next run to avoid the scan entirely if -the files are still dirty. However, the benchmarks above were performed in a clean repository where -these shortcuts do not trigger. All benchmarked tools had to do the same work -- check the status -of every file in the index to see if it has changed, check every directory for newly created files, -etc. And yet, gitstatusd came ahead by a large margin. This section describes what it does that -makes it so fast. - -Most of the following comparisons are done against libgit2 rather than git because of the author's -familiarity with the former but not the with latter. libgit2 has clean, well-documented APIs and an -elegant implementation, which makes it so much easier to work with and to analyze performance -bottlenecks. - -### Summary for the impatient - -Under the benchmark conditions described above, the equivalent of libgit2's -`git_diff_index_to_workdir` (the most expensive part of `status` command) is 46.3 times faster in -gitstatusd. The speedup comes from the following sources. - -* gitstatusd uses more efficient data structures and algorithms and employs performance-conscious -coding style throughout the codebase. This reduces CPU time in userspace by 32x compared to libgit2. -* gitstatusd uses less expensive system calls and makes fewer of them. This reduces CPU time spent -in kernel by 1.9x. -* gitstatusd can utilize multiple cores to scan index and workdir in parallel with almost perfect -scaling. This reduces total run time by 12.4x while having virtually no effect on total CPU time. - -### Problem statement - -The most resource-intensive part of the `status` command is finding the difference between _index_ -and _workdir_ (`git_diff_index_to_workdir` in libgit2). Index is a list of all files in the git -repository with their last modification times. This is an obvious simplification but it suffices for -this exposition. On disk, index is stored sorted by file path. Here's an example of git index: - -| File | Last modification time | -|-------------|-----------------------:| -| Makefile | 2019-04-01T14:12:32Z | -| src/hello.c | 2019-04-01T14:12:00Z | -| src/hello.h | 2019-04-01T14:12:32Z | - -This list needs to be compared to the list of files in the working directory. If any of the files -listed in the index are missing from the workdir or have different last modification time, they are -"unstaged" in gitstatusd parlance. If you run `git status`, they'll be shown as "changes not staged -for commit". Thus, any implementation of `status` command has to call `stat()` or one of its -variants on every file in the index. - -In addition, all files in the working directory for which there is no entry in the index at all are -"untracked". `git status` will show them as "untracked files". Finding untracked files requires some -form of work directory traversal. - -### Single-threaded scan - -Let's see how `git_diff_index_to_workdir` from libgit2 accomplishes these tasks. Here's its CPU -profile from 200 hot runs over chromium repository. - - - -(The CPU profile was created with [gperftools](https://github.com/gperftools/gperftools) and -rendered with [pprof](https://github.com/google/pprof)). - -We can see `__GI__lxstat` taking a lot of time. This is the `stat()` call for every file in the -index. We can also identify `__opendir`, `__readdir` and `__GI___close_nocancel` -- glibc wrappers -for reading the contents of a directory. This is for finding untracked files. Out of the total 232 -seconds, 111 seconds -- or 47.7% -- was spent on these calls. The rest is computation -- comparing -strings, sorting arrays, etc. - -Now let's take a look at the CPU profile of gitstatusd on the same task. - - - -The first impression is that this profile looks pruned. This isn't an artifact. The profile was -generated with the same tools and the same flags as the profile of libgit2. - -Since both profiles were generated from the same workload, absolute numbers can be compared. We can -see that gitstatusd took 62 seconds in total compared to libgit2's 232 seconds. System calls at the -core of the algorithm are clearly visible. `__GI___fxstatat` is a flavor of `stat()`, and the other -three calls -- `__libc_openat64`, `__libc_close` and `__GI___fxstat` are responsible for opening -directories and finding untracked files. Notice that there is almost nothing else in the profile -apart from these calls. The rest of the code accounts for 3.77 seconds of CPU time -- 32 times less -than in libgit2. - -So, one reason gitstatusd is fast is that it has efficient diffing code -- very little time is spent -outside of kernel. However, if we look closely, we can notice that system calls in gitstatusd are -_also_ faster than in libgit2. For example, libgit2 spent 72.07 seconds in `__GI__lxstat` while -gitstatusd spent only 48.82 seconds in `__GI___fxstatat`. There are two reasons for this difference. -First, libgit2 makes more `stat()` calls than is strictly required. It's not necessary to stat -directories because index only has files. There are 25k directories in chromium repository (and 300k -files) -- that's 25k `stat()` calls that could be avoided. The second reason is that libgit2 and -gitstatusd use different flavors of `stat()`. libgit2 uses `lstat()`, which takes a path to the file -as input. Its performance is linear in the number of subdirectories in the path because it needs to -perform a lookup for every one of them and to check permissions. gitstatusd uses `fstatat()`, which -takes a file descriptor to the parent directory and a name of the file. Just a single lookup, less -CPU time. - -Similarly to `lstat()` vs `fstatat()`, it's faster to open files and directories with `openat()` -from the parent directory file descriptor than with regular `open()` that accepts full file path. -gitstatusd takes advantage of `openat()` to open directories as fast as possible. It opens about 90% -of the directories (this depends on the actual directory structure of the repository) from the -immediate parent -- the most efficient way -- and the remaining 10% it opens from the repository's -root directory. The reason it's done this way is to keep the maximum number of simultaneously open -file descriptors bounded. libgit2 can have O(repository depth) simultaneously open file descriptors, -which may be OK for a single-threaded application but can balloon to a large number when scans are -done by many threads simultaneously, like in gitstatusd. - -There is no equivalent to `__opendir` or `__readdir` in the gitstatusd profile because it uses the -equivalent of [untracked cache](https://git-scm.com/docs/git-update-index#_untracked_cache) from -git. On the first scan of the workdir gitstatusd lists all files just like libgit2. But, unlike -libgit2, it remembers the last modification time of every directory along with the list of -untracked files under it. On the next scan, gitstatusd can skip listing files in directories whose -last modification time hasn't changed. - -To summarize, here's what gitstatusd was doing when the CPU profile was captured: - -1. `__libc_openat64`: Open every directory for which there are files in the index. -2. `__GI___fxstat`: Check last modification time of the directory. Since it's the same as on the - last scan, this directory has the same list of untracked files as before, which is empty (the - repository is clean). -3. `__GI___fxstatat`: Check last modification time for every file in the index that belongs to this - directory. -4. `__libc_close`: Close the file descriptor to the directory. - -Here's how the very first scan of a repository looks like in gitstatusd: - - - -(Some glibc functions are mislabel on this profile. `explicit_bzero` and `__nss_passwd_lookup` are -in reality `strcmp` and `memcmp`.) - -This is a superset of the previous -- hot -- profile, with an extra `syscall` and string sorting for -directory listing. gitstatusd uses `getdents64` Linux system call directly, bypassing the glibc -wrapper that libgit2 uses. This is 23% faster. The details of this optimization can be found in a -[separate document](docs/listdir.md). - -### Multithreading - -The diffing algorithm in gitstatusd was designed from the ground up with the intention of using it -concurrently from multiple threads. With a fast SSD, `status` is CPU bound, so taking advantage of -all available CPU cores is an obvious way to yield results faster. - -gitstatusd exhibits almost perfect scaling from multithreading. Engaging all cores allows it to -produce results 12.4 times faster than in single-threaded execution. This is on Intel i9-7900X with -10 cores (20 with hyperthreading) with single-core frequency of 4.3GHz and all-core frequency of -4.0GHz. - -Note: `git status` also uses all available cores in some parts of its algorithm while `lg2` does -everything in a single thread. - -### Postprocessing - -Once the difference between the index and the workdir is found, we have a list of _candidates_ -- -files that may be unstaged or untracked. To make the final judgement, these files need to be checked -against `.gitignore` rules and a few other things. - -gitstatusd uses [patched libgit2](https://github.com/romkatv/libgit2) for this step. This fork -adds several optimizations that make libgit2 faster. The patched libgit2 performs more than twice -as fast in the benchmark as the original even without changes in the user code (that is, in the -code that uses the libgit2 APIs). The fork also adds several API extensions, most notable of which -is the support for multi-threaded scans. If `lg2 status` is modified to take advantage of these -extensions, it outperforms the original libgit2 by a factor of 18. Lastly, the fork fixes a score of -bugs, most of which become apparent only when using libgit2 from multiple threads. - -_WARNING: Changes to libgit2 are extensive but the testing they underwent isn't.

This optimization assumes that callers already have a descriptor to the -parent directory, which is indeed the case for gitstatusd, and is often the case in other -applications that traverse filesystem. - -```c++ -void ListDir(int parent_fd, const char* dirname, string& arena, vector<char*>& entries) { // + - entries.clear(); - int dir_fd = openat(parent_fd, dirname, O_NOATIME | O_RDONLY | O_DIRECTORY | O_CLOEXEC); // + - if (dir_fd < 0) return; // + - if (DIR* dir = fdopendir(dir_fd)) { - arena.clear(); - while (struct dirent* ent = (errno = 0, readdir(dir))) { - if (!Dots(ent->d_name)) { - entries.push_back(reinterpret_cast<char*>(arena.size())); - arena.append(ent->d_name, strlen(ent->d_name) + 1); - } - } - if (errno) entries.clear(); - for (char*& p : entries) p = &arena[reinterpret_cast<size_t>(p)]; - sort(entries.begin(), entries.end(), - [](const char* a, const char* b) { return strcmp(a, b) < 0; }); - closedir(dir); - } else { // + - close(dir_fd); // + - } // + -} -``` - -This is worth about 3.5% in speed. - -| version | optimization | score | -|---------|--------------------------------------|----------:| -| v1 | baseline | 100.0 | -| v2 | avoid heap allocations | 112.7 | -| **v3** | **open directories with `openat()`** | **116.2** | - -## v4 - -Copying file names to the arena isn't free but it doesn't seem like we can avoid it. Poking around -we can see that the POSIX API we are using is implemented on Linux on top of `getdents64` system -call. Its documentation isn't very encouraging: - -```text -These are not the interfaces you are interested in. Look at -readdir(3) for the POSIX-conforming C library interface. This page -documents the bare kernel system call interfaces. - -Note: There are no glibc wrappers for these system calls. -``` - -Hmm... The API looks like something we can take advantage of, so let's try it anyway. - -First, we'll need a simple `Arena` class that can allocate 8KB blocks of memory. - -```c++ -class Arena { - public: - enum { kBlockSize = 8 << 10 }; - - char* Alloc() { - if (cur_ == blocks_.size()) blocks_.emplace_back(kBlockSize, 0); - return blocks_[cur_++].data(); - } - - void Clear() { cur_ = 0; } - - private: - size_t cur_ = 0; - vector<string> blocks_; -}; -``` - -Next, we need to define `struct dirent64_t` ourselves because there is no wrapper for the system -call we are about to use. - -```c++ -struct dirent64_t { - ino64_t d_ino; - off64_t d_off; - unsigned short d_reclen; - unsigned char d_type; - char d_name[]; -}; -``` - -Finally we can get to the implementation of `ListDir()`. - -```c++ -void ListDir(int parent_fd, Arena& arena, vector<char*>& entries) { // + - entries.clear(); - int dir_fd = openat(parent_fd, dirname, O_NOATIME | O_RDONLY | O_DIRECTORY | O_CLOEXEC); - if (dir_fd < 0) return; - arena.Clear(); // + - while (true) { // + - char* buf = arena.Alloc(); // + - int n = syscall(SYS_getdents64, dir_fd, buf, Arena::kBlockSize); // + - if (n <= 0) { // + - if (n) entries.clear(); // + - break; // + - } // + - for (int pos = 0; pos < n;) { // + - auto* ent = reinterpret_cast<dirent64_t*>(buf + pos); // + - if (!Dots(ent->d_name)) entries.push_back(ent->d_name); // + - pos += ent->d_reclen; // + - } // + - } // + - sort(entries.begin(), entries.end(), - [](const char* a, const char* b) { return strcmp(a, b) < 0; }); - close(dir_fd); -} -``` - -How are we doing with this one? - -| version | optimization | score | -|---------|----------------------------------|----------:| -| v1 | baseline | 100.0 | -| v2 | avoid heap allocations | 112.7 | -| v3 | open directories with `openat()` | 116.2 | -| **v4** | **call `getdents64()` directly** | **137.8** | - -Solid 20% speedup. Worth the trouble. Unfortunately, we now have just one `reinterpret_cast` instead -of two, and it's not nearly as scary-looking. Hopefully with the next iteration we can get back some -of that evil vibe of low-level code. - -As a bonus, every element in `entries` has `d_type` at offset -1. This can be useful to the callers -that need to distinguish between regular files and directories (gitstatusd, in fact, needs this). -Note how `ListDir()` implements this feature at zero cost, as a lucky accident of `dirent64_t` -memory layout. - -## v5 - -The CPU profile of `ListDir()` reveals that almost all userspace CPU time is spent in `strcmp()`. -Digging into the source code of `std::sort()` we can see that it uses Insertion Sort for short -collections. Our 32-element vector falls under the threshold. Insertion Sort makes `O(N^2)` -comparisons, hence a lot of CPU time in `strcmp()`. Switching to `qsort()` or -[Timsort](https://en.wikipedia.org/wiki/Timsort) is of no use as all good sorting algorithms fall -back to Insertion Sort. - -If we cannot make fewer comparisons, perhaps we can make each of them faster? `strcmp()` compares -characters one at a time. It cannot read ahead as it can be illegal to touch memory past the first -null byte. But _we_ know that it's safe to read a few extra bytes past the end of `d_name` for every -entry except the last in the buffer. And since we own the buffer, we can overallocate it so that -reading past the end of the last entry is also safe. - -Combining these ideas with the fact that file names on Linux are at most 255 bytes long, we can -invoke `getdents64()` like this: - -```c++ -int n = syscall(SYS_getdents64, dir_fd, buf, Arena::kBlockSize - 256); -``` - -And then compare entries like this: - -```c++ -[](const char* a, const char* b) { return memcmp(a, b, 255) < 0; } -``` - -This version doesn't give any speedup compared to the previous but it opens an avenue for another -optimization. The pointers we pass to `memcmp()` aren't aligned. To be more specific, their -numerical values are `N * 8 + 3` for some `N`. When given such a pointer, `memcmp()` will check the -first 5 bytes one by one, and only then switch to comparing 8 bytes at a time. If we can handle the -first 5 bytes ourselves, we can pass aligned memory to `memcmp()` and take full advantage of its -vectorized loop. - -Here's the implementation: - -```c++ -uint64_t Read64(const void* p) { // + - uint64_t x; // + - memcpy(&x, p, sizeof(x)); // + - return x; // + -} // + - -void ByteSwap64(void* p) { // + - uint64_t x = __builtin_bswap64(Read64(p)); // + - memcpy(p, &x, sizeof(x)); // + -} // + - -void ListDir(int parent_fd, Arena& arena, vector<char*>& entries) { - entries.clear(); - int dir_fd = openat(parent_fd, dirname, O_NOATIME | O_RDONLY | O_DIRECTORY | O_CLOEXEC); - if (dir_fd < 0) return; - arena.Clear(); - while (true) { - char* buf = arena.Alloc(); - int n = syscall(SYS_getdents64, dir_fd, buf, Arena::kBlockSize - 256); // + - if (n <= 0) { - if (n) entries.clear(); - break; - } - for (int pos = 0; pos < n;) { - auto* ent = reinterpret_cast<dirent64_t*>(buf + pos); - if (!Dots(ent->d_name)) { - ByteSwap64(ent->d_name); // + - entries.push_back(ent->d_name); - } - pos += ent->d_reclen; - } - } - sort(entries.begin(), entries.end(), [](const char* a, const char* b) { - uint64_t x = Read64(a); // + - uint64_t y = Read64(b); // + - return x < y || (x == y && a != b && memcmp(a + 5, b + 5, 256) < 0); // + - }); - for (char* p : entries) ByteSwap64(p); // + - close(dir_fd); -} -``` - -This is for Little Endian architecture.
