If this is the case for your PR, make sure + the corresponding issue is mentioned. If your change 'fixes' or completely addresses the + issue at hand, then please indicate this by requesting that an issue be closed by commenting. + * Just because your changes have been merged does not mean the topic or larger issue is complete. Remember + that the change must make it to an official zstd release for it to be meaningful. We recommend + that contributors track the activity on their pull request and corresponding issue(s) page(s) until + their change makes it to the next release of zstd. Users will often discover bugs in your code or + suggest ways to refine and improve your initial changes even after the pull request is merged. + +## Static Analysis +Static analysis is a process for examining the correctness or validity of a program without actually +executing it. It usually helps us find many simple bugs. Zstd uses clang's `scan-build` tool for +static analysis. You can install it by following the instructions for your OS on https://clang-analyzer.llvm.org/scan-build. + +Once installed, you can ensure that our static analysis tests pass on your local development machine +by running: +``` +make staticAnalyze +``` + +In general, you can use `scan-build` to static analyze any build script. For example, to static analyze +just `contrib/largeNbDicts` and nothing else, you can run: + +``` +scan-build make -C contrib/largeNbDicts largeNbDicts +``` + +### Pitfalls of static analysis +`scan-build` is part of our regular CI suite. Other static analyzers are not. + +It can be useful to look at additional static analyzers once in a while (and we do), but it's not a good idea to multiply the nb of analyzers run continuously at each commit and PR. The reasons are : + +- Static analyzers are full of false positive. The signal to noise ratio is actually pretty low. +- A good CI policy is "zero-warning tolerance". That means that all issues must be solved, including false positives. This quickly becomes a tedious workload. +- Multiple static analyzers will feature multiple kind of false positives, sometimes applying to the same code but in different ways leading to : + + tortuous code, trying to please multiple constraints, hurting readability and therefore maintenance. Sometimes, such complexity introduce other more subtle bugs, that are just out of scope of the analyzers. + + sometimes, these constraints are mutually exclusive : if one try to solve one, the other static analyzer will complain, they can't be both happy at the same time. +- As if that was not enough, the list of false positives change with each version. It's hard enough to follow one static analyzer, but multiple ones with their own update agenda, this quickly becomes a massive velocity reducer. + +This is different from running a static analyzer once in a while, looking at the output, and __cherry picking__ a few warnings that seem helpful, either because they detected a genuine risk of bug, or because it helps expressing the code in a way which is more readable or more difficult to misuse. These kinds of reports can be useful, and are accepted. + +## Continuous Integration +CI tests run every time a pull request (PR) is created or updated. The exact tests +that get run will depend on the destination branch you specify. Some tests take +longer to run than others. Currently, our CI is set up to run a short +series of tests when creating a PR to the dev branch and a longer series of tests +when creating a PR to the release branch. You can look in the configuration files +of the respective CI platform for more information on what gets run when. + +Most people will just want to create a PR with the destination set to their local dev +branch of zstd. You can then find the status of the tests on the PR's page. You can also +re-run tests and cancel running tests from the PR page or from the respective CI's dashboard. + +Almost all of zstd's CI runs on GitHub Actions (configured at `.github/workflows`), which will automatically run on PRs to your +own fork. A small number of tests run on other services (e.g. Travis CI, Circle CI, Appveyor). +These require work to set up on your local fork, and (at least for Travis CI) cost money. +Therefore, if the PR on your local fork passes GitHub Actions, feel free to submit a PR +against the main repo. + +### Third-party CI +A small number of tests cannot run on GitHub Actions, or have yet to be migrated. +For these, we use a variety of third-party services (listed below). It is not necessary to set +these up on your fork in order to contribute to zstd; however, we do link to instructions for those +who want earlier signal. + +| Service | Purpose | Setup Links | Config Path | +|-----------|------------------------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------------|------------------------| +| Travis CI | Used for testing on non-x86 architectures such as PowerPC | https://docs.travis-ci.com/user/tutorial/#to-get-started-with-travis-ci-using-github

https://youtu.be/Js3hMUsSZ2c
https://circleci.com/docs/2.0/enable-checks/ | `.circleci/config.yml` | + +Note: the instructions linked above mostly cover how to set up a repository with CI from scratch. +The general idea should be the same for setting up CI on your fork of zstd, but you may have to +follow slightly different steps. In particular, please ignore any instructions related to setting up +config files (since zstd already has configs for each of these services). + +## Performance +Performance is extremely important for zstd and we only merge pull requests whose performance +landscape and corresponding trade-offs have been adequately analyzed, reproduced, and presented. +This high bar for performance means that every PR which has the potential to +impact performance takes a very long time for us to properly review. That being said, we +always welcome contributions to improve performance (or worsen performance for the trade-off of +something else). Please keep the following in mind before submitting a performance related PR: + +1. Zstd isn't as old as gzip but it has been around for time now and its evolution is +very well documented via past Github issues and pull requests. It may be the case that your +particular performance optimization has already been considered in the past. Please take some +time to search through old issues and pull requests using keywords specific to your +would-be PR. Of course, just because a topic has already been discussed (and perhaps rejected +on some grounds) in the past, doesn't mean it isn't worth bringing up again. But even in that case, +it will be helpful for you to have context from that topic's history before contributing. +2. The distinction between noise and actual performance gains can unfortunately be very subtle +especially when microbenchmarking extremely small wins or losses. The only remedy to getting +something subtle merged is extensive benchmarking. You will be doing us a great favor if you +take the time to run extensive, long-duration, and potentially cross-(os, platform, process, etc) +benchmarks on your end before submitting a PR. Of course, you will not be able to benchmark +your changes on every single processor and os out there (and neither will we) but do that best +you can:) We've added some things to think about when benchmarking below in the Benchmarking +Performance section which might be helpful for you. +3. Optimizing performance for a certain OS, processor vendor, compiler, or network system is a perfectly +legitimate thing to do as long as it does not harm the overall performance health of Zstd. +This is a hard balance to strike but please keep in mind other aspects of Zstd when +submitting changes that are clang-specific, windows-specific, etc. + +## Benchmarking Performance +Performance microbenchmarking is a tricky subject but also essential for Zstd. We value empirical +testing over theoretical speculation. This guide it not perfect but for most scenarios, it +is a good place to start. + +### Stability +Unfortunately, the most important aspect in being able to benchmark reliably is to have a stable +benchmarking machine. A virtual machine, a machine with shared resources, or your laptop +will typically not be stable enough to obtain reliable benchmark results. If you can get your +hands on a desktop, this is usually a better scenario. + +Of course, benchmarking can be done on non-hyper-stable machines as well. You will just have to +do a little more work to ensure that you are in fact measuring the changes you've made not and +noise. Here are some things you can do to make your benchmarks more stable: + +1. The most simple thing you can do to drastically improve the stability of your benchmark is +to run it multiple times and then aggregate the results of those runs. As a general rule of +thumb, the smaller the change you are trying to measure, the more samples of benchmark runs +you will have to aggregate over to get reliable results. Here are some additional things to keep in +mind when running multiple trials: + * How you aggregate your samples are important. You might be tempted to use the mean of your + results. While this is certainly going to be a more stable number than a raw single sample + benchmark number, you might have more luck by taking the median. The mean is not robust to + outliers whereas the median is. Better still, you could simply take the fastest speed your + benchmark achieved on each run since that is likely the fastest your process will be + capable of running your code. In our experience, this (aggregating by just taking the sample + with the fastest running time) has been the most stable approach. + * The more samples you have, the more stable your benchmarks should be. You can verify + your improved stability by looking at the size of your confidence intervals as you + increase your sample count. These should get smaller and smaller. Eventually hopefully + smaller than the performance win you are expecting. + * Most processors will take some time to get `hot` when running anything. The observations + you collect during that time period will very different from the true performance number. Having + a very large number of sample will help alleviate this problem slightly but you can also + address is directly by simply not including the first `n` iterations of your benchmark in + your aggregations. You can determine `n` by simply looking at the results from each iteration + and then hand picking a good threshold after which the variance in results seems to stabilize. +2. You cannot really get reliable benchmarks if your host machine is simultaneously running +another cpu/memory-intensive application in the background. If you are running benchmarks on your +personal laptop for instance, you should close all applications (including your code editor and +browser) before running your benchmarks. You might also have invisible background applications +running. You can see what these are by looking at either Activity Monitor on Mac or Task Manager +on Windows. You will get more stable benchmark results of you end those processes as well. + * If you have multiple cores, you can even run your benchmark on a reserved core to prevent + pollution from other OS and user processes. There are a number of ways to do this depending + on your OS: + * On linux boxes, you have use https://github.com/lpechacek/cpuset. + * On Windows, you can "Set Processor Affinity" using https://www.thewindowsclub.com/processor-affinity-windows + * On Mac, you can try to use their dedicated affinity API https://developer.apple.com/library/archive/releasenotes/Performance/RN-AffinityAPI/#//apple_ref/doc/uid/TP40006635-CH1-DontLinkElementID_2 +3. To benchmark, you will likely end up writing a separate c/c++ program that will link libzstd. +Dynamically linking your library will introduce some added variation (not a large amount but +definitely some). Statically linking libzstd will be more stable. Static libraries should +be enabled by default when building zstd. +4. Use a profiler with a good high resolution timer. See the section below on profiling for +details on this. +5. Disable frequency scaling, turbo boost and address space randomization (this will vary by OS) +6. Try to avoid storage. On some systems you can use tmpfs. Putting the program, inputs and outputs on +tmpfs avoids touching a real storage system, which can have a pretty big variability. + +Also check our LLVM's guide on benchmarking here: https://llvm.org/docs/Benchmarking.html + +### Zstd benchmark +The fastest signal you can get regarding your performance changes is via the in-build zstd cli +bench option. You can run Zstd as you typically would for your scenario using some set of options +and then additionally also specify the `-b#` option. Doing this will run our benchmarking pipeline +for that options you have just provided. If you want to look at the internals of how this +benchmarking script works, you can check out programs/benchzstd.c + +For example: say you have made a change that you believe improves the speed of zstd level 1. The +very first thing you should use to assess whether you actually achieved any sort of improvement +is `zstd -b`. You might try to do something like this. Note: you can use the `-i` option to +specify a running time for your benchmark in seconds (default is 3 seconds). +Usually, the longer the running time, the more stable your results will be. + +``` +$ git checkout +$ make && cp zstd zstd-old +$ git checkout +$ make && cp zstd zstd-new +$ zstd-old -i5 -b1 + 1 : 8990 -> 3992 (2.252), 302.6 MB/s , 626.4 MB/s +$ zstd-new -i5 -b1 + 1 : 8990 -> 3992 (2.252), 302.8 MB/s , 628.4 MB/s +``` + +Unless your performance win is large enough to be visible despite the intrinsic noise +on your computer, benchzstd alone will likely not be enough to validate the impact of your +changes. For example, the results of the example above indicate that effectively nothing +changed but there could be a small <3% improvement that the noise on the host machine +obscured. So unless you see a large performance win (10-15% consistently) using just +this method of evaluation will not be sufficient. + +### Profiling +There are a number of great profilers out there. We're going to briefly mention how you can +profile your code using `instruments` on mac, `perf` on linux and `visual studio profiler` +on Windows. + +Say you have an idea for a change that you think will provide some good performance gains +for level 1 compression on Zstd. Typically this means, you have identified a section of +code that you think can be made to run faster. + +The first thing you will want to do is make sure that the piece of code is actually taking up +a notable amount of time to run. It is usually not worth optimizing something which accounts for less than +0.0001% of the total running time. Luckily, there are tools to help with this. +Profilers will let you see how much time your code spends inside a particular function. +If your target code snippet is only part of a function, it might be worth trying to +isolate that snippet by moving it to its own function (this is usually not necessary but +might be). + +Most profilers (including the profilers discussed below) will generate a call graph of +functions for you. Your goal will be to find your function of interest in this call graph +and then inspect the time spent inside of it. You might also want to look at the annotated +assembly which most profilers will provide you with. + +#### Instruments +We will once again consider the scenario where you think you've identified a piece of code +whose performance can be improved upon. Follow these steps to profile your code using +Instruments. + +1. Open Instruments +2. Select `Time Profiler` from the list of standard templates +3. Close all other applications except for your instruments window and your terminal +4. Run your benchmarking script from your terminal window + * You will want a benchmark that runs for at least a few seconds (5 seconds will + usually be long enough). This way the profiler will have something to work with + and you will have ample time to attach your profiler to this process:) + * I will just use benchzstd as my benchmarmking script for this example: +``` +$ zstd -b1 -i5 # this will run for 5 seconds +``` +5. Once you run your benchmarking script, switch back over to instruments and attach your +process to the time profiler. You can do this by: + * Clicking on the `All Processes` drop down in the top left of the toolbar. + * Selecting your process from the dropdown. In my case, it is just going to be labeled + `zstd` + * Hitting the bright red record circle button on the top left of the toolbar +6. You profiler will now start collecting metrics from your benchmarking script. Once +you think you have collected enough samples (usually this is the case after 3 seconds of +recording), stop your profiler. +7. Make sure that in toolbar of the bottom window, `profile` is selected. +8. You should be able to see your call graph. + * If you don't see the call graph or an incomplete call graph, make sure you have compiled + zstd and your benchmarking script using debug flags. On mac and linux, this just means + you will have to supply the `-g` flag alone with your build script. You might also + have to provide the `-fno-omit-frame-pointer` flag +9. Dig down the graph to find your function call and then inspect it by double clicking +the list item. You will be able to see the annotated source code and the assembly side by +side. + +#### Perf + +This wiki has a pretty detailed tutorial on getting started working with perf so we'll +leave you to check that out of you're getting started: + +https://perf.wiki.kernel.org/index.php/Tutorial + +Some general notes on perf: +* Use `perf stat -r # ` to quickly get some relevant timing and +counter statistics. Perf uses a high resolution timer and this is likely one +of the first things your team will run when assessing your PR. +* Perf has a long list of hardware counters that can be viewed with `perf --list`. +When measuring optimizations, something worth trying is to make sure the hardware +counters you expect to be impacted by your change are in fact being so. For example, +if you expect the L1 cache misses to decrease with your change, you can look at the +counter `L1-dcache-load-misses` +* Perf hardware counters will not work on a virtual machine. + +#### Visual Studio + +TODO + +## Issues +We use GitHub issues to track public bugs. Please ensure your description is +clear and has sufficient instructions to be able to reproduce the issue. + +Facebook has a [bounty program](https://www.facebook.com/whitehat/) for the safe +disclosure of security bugs. In those cases, please go through the process +outlined on that page and do not file a public issue. + +## Coding Style +It's a pretty long topic, which is difficult to summarize in a single paragraph. +As a rule of thumbs, try to imitate the coding style of +similar lines of codes around your contribution. +The following is a non-exhaustive list of rules employed in zstd code base: + +### C90 +This code base is following strict C90 standard, +with 2 extensions : 64-bit `long long` types, and variadic macros. +This rule is applied strictly to code within `lib/` and `programs/`. +Sub-project in `contrib/` are allowed to use other conventions. + +### C++ direct compatibility : symbol mangling +All public symbol declarations must be wrapped in `extern “C” { … }`, +so that this project can be compiled as C++98 code, +and linked into C++ applications. + +### Minimal Frugal +This design requirement is fundamental to preserve the portability of the code base. +#### Dependencies +- Reduce dependencies to the minimum possible level. + Any dependency should be considered “bad” by default, + and only tolerated because it provides a service in a better way than can be achieved locally. + The only external dependencies this repository tolerates are + standard C libraries, and in rare cases, system level headers. +- Within `lib/`, this policy is even more drastic. + The only external dependencies allowed are ``, ``, ``, + and even then, not directly. + In particular, no function shall ever allocate on heap directly, + and must use instead `ZSTD_malloc()` and equivalent. + Other accepted non-symbol headers are `` and ``. +- Within the project, there is a strict hierarchy of dependencies that must be respected. + `programs/` is allowed to depend on `lib/`, but only its public API. + Within `lib/`, `lib/common` doesn't depend on any other directory. + `lib/compress` and `lib/decompress` shall not depend on each other. + `lib/dictBuilder` can depend on `lib/common` and `lib/compress`, but not `lib/decompress`. +#### Resources +- Functions in `lib/` must use very little stack space, + several dozens of bytes max. + Everything larger must use the heap allocator, + or require a scratch buffer to be emplaced manually. + +### Naming +* All public symbols are prefixed with `ZSTD_` + + private symbols, with a scope limited to their own unit, are free of this restriction. + However, since `libzstd` source code can be amalgamated, + each symbol name must attempt to be (and remain) unique. + Avoid too generic names that could become ground for future collisions. + This generally implies usage of some form of prefix. +* For symbols (functions and variables), naming convention is `PREFIX_camelCase`. + + In some advanced cases, one can also find : + - `PREFIX_prefix2_camelCase` + - `PREFIX_camelCase_extendedQualifier` +* Multi-words names generally consist of an action followed by object: + - for example : `ZSTD_createCCtx()` +* Prefer positive actions + - `goBackward` rather than `notGoForward` +* Type names (`struct`, etc.) follow similar convention, + except that they are allowed and even invited to start by an Uppercase letter. + Example : `ZSTD_CCtx`, `ZSTD_CDict` +* Macro names are all Capital letters. + The same composition rules (`PREFIX_NAME_QUALIFIER`) apply. +* File names are all lowercase letters. + The convention is `snake_case`. + File names **must** be unique across the entire code base, + even when they stand in clearly separated directories. + +### Qualifiers +* This code base is `const` friendly, if not `const` fanatical. + Any variable that can be `const` (aka. read-only) **must** be `const`. + Any pointer which content will not be modified must be `const`. + This property is then controlled at compiler level. + `const` variables are an important signal to readers that this variable isn't modified. + Conversely, non-const variables are a signal to readers to watch out for modifications later on in the function. +* If a function must be inlined, mention it explicitly, + using project's own portable macros, such as `FORCE_INLINE_ATTR`, + defined in `lib/common/compiler.h`. + +### Debugging +* **Assertions** are welcome, and should be used very liberally, + to control any condition the code expects for its correct execution. + These assertion checks will be run in debug builds, and disabled in production. +* For traces, this project provides its own debug macros, + in particular `DEBUGLOG(level, ...)`, defined in `lib/common/debug.h`. + +### Code documentation +* Avoid code documentation that merely repeats what the code is already stating. + Whenever applicable, prefer employing the code as the primary way to convey explanations. + Example 1 : `int nbTokens = n;` instead of `int i = n; /* i is a nb of tokens *./`. + Example 2 : `assert(size > 0);` instead of `/* here, size should be positive */`. +* At declaration level, the documentation explains how to use the function or variable + and when applicable why it's needed, of the scenarios where it can be useful. +* At implementation level, the documentation explains the general outline of the algorithm employed, + and when applicable why this specific choice was preferred. + +### General layout +* 4 spaces for indentation rather than tabs +* Code documentation shall directly precede function declaration or implementation +* Function implementations and its code documentation should be preceded and followed by an empty line + + +## License +By contributing to Zstandard, you agree that your contributions will be licensed +under both the [LICENSE](LICENSE) file and the [COPYING](COPYING) file in the root directory of this source tree. diff --git a/3rdparty/zstd/COPYING b/3rdparty/zstd/COPYING new file mode 100644 index 00000000000..ecbc0593737 --- /dev/null +++ b/3rdparty/zstd/COPYING @@ -0,0 +1,339 @@ + GNU GENERAL PUBLIC LICENSE + Version 2, June 1991 + + Copyright (C) 1989, 1991 Free Software Foundation, Inc., + 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Lesser General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License along + with this program; if not, write to the Free Software Foundation, Inc., + 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary. Here is a sample; alter the names: + + Yoyodyne, Inc., hereby disclaims all copyright interest in the program + `Gnomovision' (which makes passes at compilers) written by James Hacker. + + , 1 April 1989 + Ty Coon, President of Vice + +This General Public License does not permit incorporating your program into +proprietary programs. If your program is a subroutine library, you may +consider it more useful to permit linking proprietary applications with the +library.

Zstandard

+ +__Zstandard__, or `zstd` as short version, is a fast lossless compression algorithm, +targeting real-time compression scenarios at zlib-level and better compression ratios. +It's backed by a very fast entropy stage, provided by [Huff0 and FSE library](https://github.com/Cyan4973/FiniteStateEntropy). + +Zstandard's format is stable and documented in [RFC8878](https://datatracker.ietf.org/doc/html/rfc8878). Multiple independent implementations are already available. +This repository represents the reference implementation, provided as an open-source dual [BSD](LICENSE) and [GPLv2](COPYING) licensed **C** library, +and a command line utility producing and decoding `.zst`, `.gz`, `.xz` and `.lz4` files. +Should your project require another programming language, +a list of known ports and bindings is provided on [Zstandard homepage](https://facebook.github.io/zstd/#other-languages). + +**Development branch status:** + +[![Build Status][travisDevBadge]][travisLink] +[![Build status][CircleDevBadge]][CircleLink] +[![Build status][CirrusDevBadge]][CirrusLink] +[![Fuzzing Status][OSSFuzzBadge]][OSSFuzzLink] + +[travisDevBadge]: https://api.travis-ci.com/facebook/zstd.svg?branch=dev "Continuous Integration test suite" +[travisLink]: https://travis-ci.com/facebook/zstd +[CircleDevBadge]: https://circleci.com/gh/facebook/zstd/tree/dev.svg?style=shield "Short test suite" +[CircleLink]: https://circleci.com/gh/facebook/zstd +[CirrusDevBadge]: https://api.cirrus-ci.com/github/facebook/zstd.svg?branch=dev +[CirrusLink]: https://cirrus-ci.com/github/facebook/zstd +[OSSFuzzBadge]: https://oss-fuzz-build-logs.storage.googleapis.com/badges/zstd.svg +[OSSFuzzLink]: https://bugs.chromium.org/p/oss-fuzz/issues/list?sort=-opened&can=1&q=proj:zstd + +## Benchmarks + +For reference, several fast compression algorithms were tested and compared +on a desktop running Ubuntu 20.04 (`Linux 5.11.0-41-generic`), +with a Core i7-9700K CPU @ 4.9GHz, +using [lzbench], an open-source in-memory benchmark by @inikep +compiled with [gcc] 9.3.0, +on the [Silesia compression corpus]. + +[lzbench]: https://github.com/inikep/lzbench +[Silesia compression corpus]: https://sun.aei.polsl.pl//~sdeor/index.php?page=silesia +[gcc]: https://gcc.gnu.org/ + +| Compressor name | Ratio | Compression| Decompress.| +| --------------- | ------| -----------| ---------- | +| **zstd 1.5.1 -1** | 2.887 | 530 MB/s | 1700 MB/s | +| [zlib] 1.2.11 -1 | 2.743 | 95 MB/s | 400 MB/s | +| brotli 1.0.9 -0 | 2.702 | 395 MB/s | 450 MB/s | +| **zstd 1.5.1 --fast=1** | 2.437 | 600 MB/s | 2150 MB/s | +| **zstd 1.5.1 --fast=3** | 2.239 | 670 MB/s | 2250 MB/s | +| quicklz 1.5.0 -1 | 2.238 | 540 MB/s | 760 MB/s | +| **zstd 1.5.1 --fast=4** | 2.148 | 710 MB/s | 2300 MB/s | +| lzo1x 2.10 -1 | 2.106 | 660 MB/s | 845 MB/s | +| [lz4] 1.9.3 | 2.101 | 740 MB/s | 4500 MB/s | +| lzf 3.6 -1 | 2.077 | 410 MB/s | 830 MB/s | +| snappy 1.1.9 | 2.073 | 550 MB/s | 1750 MB/s | + +[zlib]: https://www.zlib.net/ +[lz4]: https://lz4.github.io/lz4/ + +The negative compression levels, specified with `--fast=#`, +offer faster compression and decompression speed +at the cost of compression ratio (compared to level 1). + +Zstd can also offer stronger compression ratios at the cost of compression speed. +Speed vs Compression trade-off is configurable by small increments. +Decompression speed is preserved and remains roughly the same at all settings, +a property shared by most LZ compression algorithms, such as [zlib] or lzma. + +The following tests were run +on a server running Linux Debian (`Linux version 4.14.0-3-amd64`) +with a Core i7-6700K CPU @ 4.0GHz, +using [lzbench], an open-source in-memory benchmark by @inikep +compiled with [gcc] 7.3.0, +on the [Silesia compression corpus]. + +Compression Speed vs Ratio | Decompression Speed +---------------------------|-------------------- +![Compression Speed vs Ratio](doc/images/CSpeed2.png "Compression Speed vs Ratio") | ![Decompression Speed](doc/images/DSpeed3.png "Decompression Speed") + +A few other algorithms can produce higher compression ratios at slower speeds, falling outside of the graph. +For a larger picture including slow modes, [click on this link](doc/images/DCspeed5.png). + + +## The case for Small Data compression + +Previous charts provide results applicable to typical file and stream scenarios (several MB). Small data comes with different perspectives. + +The smaller the amount of data to compress, the more difficult it is to compress. This problem is common to all compression algorithms, and reason is, compression algorithms learn from past data how to compress future data. But at the beginning of a new data set, there is no "past" to build upon. + +To solve this situation, Zstd offers a __training mode__, which can be used to tune the algorithm for a selected type of data. +Training Zstandard is achieved by providing it with a few samples (one file per sample). The result of this training is stored in a file called "dictionary", which must be loaded before compression and decompression. +Using this dictionary, the compression ratio achievable on small data improves dramatically. + +The following example uses the `github-users` [sample set](https://github.com/facebook/zstd/releases/tag/v1.1.3), created from [github public API](https://developer.github.com/v3/users/#get-all-users). +It consists of roughly 10K records weighing about 1KB each. + +Compression Ratio | Compression Speed | Decompression Speed +------------------|-------------------|-------------------- +![Compression Ratio](doc/images/dict-cr.png "Compression Ratio") | ![Compression Speed](doc/images/dict-cs.png "Compression Speed") | ![Decompression Speed](doc/images/dict-ds.png "Decompression Speed") + + +These compression gains are achieved while simultaneously providing _faster_ compression and decompression speeds. + +Training works if there is some correlation in a family of small data samples. The more data-specific a dictionary is, the more efficient it is (there is no _universal dictionary_). +Hence, deploying one dictionary per type of data will provide the greatest benefits. +Dictionary gains are mostly effective in the first few KB.

` header and show also all functions until first empty line +- comments of type `/*X` where `X` is different from above-mentioned are ignored + +Moreover: +- `ZSTDLIB_API` is removed to improve readability +- `typedef` are detected and included even if uncommented +- comments of type `/**<` and `/*!<` are detected and only function declaration is highlighted (bold) + + +#### Usage + +The program requires 3 parameters: +``` +gen_html [zstd_version] [input_file] [output_html] +``` + +To compile program and generate zstd manual we have used: +``` +make +./gen_html.exe 1.1.1 ../../lib/zstd.h zstd_manual.html +``` diff --git a/3rdparty/zstd/contrib/gen_html/gen-zstd-manual.sh b/3rdparty/zstd/contrib/gen_html/gen-zstd-manual.sh new file mode 100755 index 00000000000..57a8b6ea512 --- /dev/null +++ b/3rdparty/zstd/contrib/gen_html/gen-zstd-manual.sh @@ -0,0 +1,9 @@ +#!/bin/sh + +LIBVER_MAJOR_SCRIPT=`sed -n '/define ZSTD_VERSION_MAJOR/s/.*[[:blank:]]\([0-9][0-9]*\).*/\1/p' < ../../lib/zstd.h` +LIBVER_MINOR_SCRIPT=`sed -n '/define ZSTD_VERSION_MINOR/s/.*[[:blank:]]\([0-9][0-9]*\).*/\1/p' < ../../lib/zstd.h` +LIBVER_PATCH_SCRIPT=`sed -n '/define ZSTD_VERSION_RELEASE/s/.*[[:blank:]]\([0-9][0-9]*\).*/\1/p' < ../../lib/zstd.h` +LIBVER_SCRIPT=$LIBVER_MAJOR_SCRIPT.$LIBVER_MINOR_SCRIPT.$LIBVER_PATCH_SCRIPT + +echo ZSTD_VERSION=$LIBVER_SCRIPT +./gen_html $LIBVER_SCRIPT ../../lib/zstd.h ./zstd_manual.html diff --git a/3rdparty/zstd/contrib/gen_html/gen_html.cpp b/3rdparty/zstd/contrib/gen_html/gen_html.cpp new file mode 100644 index 00000000000..1da5879adae --- /dev/null +++ b/3rdparty/zstd/contrib/gen_html/gen_html.cpp @@ -0,0 +1,224 @@ +/* + * Copyright (c) Meta Platforms, Inc. and affiliates. + * All rights reserved. + * + * This source code is licensed under both the BSD-style license (found in the + * LICENSE file in the root directory of this source tree) and the GPLv2 (found + * in the COPYING file in the root directory of this source tree). + */ + +#include +#include +#include +#include +using namespace std; + + +/* trim string at the beginning and at the end */ +void trim(string& s, string characters) +{ + size_t p = s.find_first_not_of(characters); + s.erase(0, p); + + p = s.find_last_not_of(characters); + if (string::npos != p) + s.erase(p+1); +} + + +/* trim C++ style comments */ +void trim_comments(string &s) +{ + size_t spos, epos; + + spos = s.find("/*"); + epos = s.find("*/"); + s = s.substr(spos+3, epos-(spos+3)); +} + + +/* get lines until a given terminator */ +vector get_lines(vector& input, int& linenum, string terminator) +{ + vector out; + string line; + size_t epos; + + while ((size_t)linenum < input.size()) { + line = input[linenum]; + + if (terminator.empty() && line.empty()) { linenum--; break; } + + epos = line.find(terminator); + if (!terminator.empty() && epos!=string::npos) { + out.push_back(line); + break; + } + out.push_back(line); + linenum++; + } + return out; +} + + +/* print line with ZSTDLIB_API removed and C++ comments not bold */ +void print_line(stringstream &sout, string line) +{ + size_t spos; + + if (line.substr(0,12) == "ZSTDLIB_API ") line = line.substr(12); + spos = line.find("/*"); + if (spos!=string::npos) { + sout << line.substr(0, spos); + sout << "" << line.substr(spos) << "" << endl; + } else { + // fprintf(stderr, "lines=%s\n", line.c_str()); + sout << line << endl; + } +} + + +int main(int argc, char *argv[]) { + char exclam; + int linenum, chapter = 1; + vector input, lines, comments, chapters; + string line, version; + size_t spos, l; + stringstream sout; + ifstream istream; + ofstream ostream; + + if (argc < 4) { + cout << "usage: " << argv[0] << " [zstd_version] [input_file] [output_html]" << endl; + return 1; + } + + version = "zstd " + string(argv[1]) + " Manual"; + + istream.open(argv[2], ifstream::in); + if (!istream.is_open()) { + cout << "Error opening file " << argv[2] << endl; + return 1; + } + + ostream.open(argv[3], ifstream::out); + if (!ostream.is_open()) { + cout << "Error opening file " << argv[3] << endl; + return 1; + } + + while (getline(istream, line)) { + input.push_back(line); + } + + for (linenum=0; (size_t)linenum < input.size(); linenum++) { + line = input[linenum]; + + /* typedefs are detected and included even if uncommented */ + if (line.substr(0,7) == "typedef" && line.find("{")!=string::npos) { + lines = get_lines(input, linenum, "}"); + sout << "

+largeNbDicts
+=====================
+
+`largeNbDicts` is a benchmark test tool
+dedicated to the specific scenario of
+dictionary decompression using a very large number of dictionaries.
+When dictionaries are constantly changing, they are always "cold",
+suffering from increased latency due to cache misses.
+
+The tool is created in a bid to investigate performance for this scenario,
+and experiment mitigation techniques.
+
+Command line :
+```
+largeNbDicts [Options] filename(s)
+
+Options : 
+-z          : benchmark compression (default) 
+-d          : benchmark decompression 
+-r          : recursively load all files in subdirectories (default: off) 
+-B#         : split input into blocks of size # (default: no split) 
+-#          : use compression level # (default: 3) 
+-D #        : use # as a dictionary (default: create one) 
+-i#         : nb benchmark rounds (default: 6) 
+--nbBlocks=#: use # blocks for bench (default: one per file) 
+--nbDicts=# : create # dictionaries for bench (default: one per block) 
+-h          : help (this text) 
+ 
+Advanced Options (see zstd.h for documentation) : 
+--dedicated-dict-search
+--dict-content-type=#
+--dict-attach-pref=#
+```

+## Upgrading Zstd in the Linux Kernel
+
+1. `cd` into this directory.
+2. Run `make libzstd` and read the output. Make sure that all the diffs printed and changes made by the script are correct.
+3. Run `make test` and ensure that it passes.
+4. Import zstd into the Linux Kernel `make import LINUX=/path/to/linux/repo`
+5. Inspect the diff for sanity.
+6. Check the Linux Kernel history for zstd. If any patches were made to the kernel version of zstd, but not to upstream zstd, then port them upstream if necessary.
+7. Test the diff. Benchmark if necessary. Make sure to test multiple architectures: At least x86, i386, and arm.
+8. Submit the patch to the LKML.
