## Workflow
Zstd uses a branch-based workflow for making changes to the codebase. Typically, zstd
will use a new branch per sizable topic. For smaller changes, it is okay to lump multiple
related changes into a branch.
Our contribution process works in three main stages:
1. Local development

* Checkout your fork of zstd if you have not already
```
git checkout https://github.com/<username>/zstd
cd zstd
```
* Update your local dev branch
```
git pull https://github.com/facebook/zstd dev
git push origin dev
```
* Topic and development:
* Make a new branch on your fork about the topic you're developing for
```
# branch names should be concise but sufficiently informative
git checkout -b <branch-name>
git push origin <branch-name>
```
* Make commits and push
```
# make some changes =
git add -u && git commit -m <message>
git push origin <branch-name>
```
* Note: run local tests to ensure that your changes didn't break existing functionality
* Quick check
```
make shortest
```
* Longer check
```
make test
```
2. Code Review and CI tests
* Ensure CI tests pass:
* Before sharing anything to the community, create a pull request in your own fork against the dev branch
and make sure that all GitHub Actions CI tests pass. See the Continuous Integration section below for more information.
* Ensure that static analysis passes on your development machine. See the Static Analysis section
below to see how to do this.
* Create a pull request:
* When you are ready to share you changes to the community, create a pull request from your branch
to facebook:dev. You can do this very easily by clicking 'Create Pull Request' on your fork's home
page.
* From there, select the branch where you made changes as your source branch and facebook:dev
as the destination.
* Examine the diff presented between the two branches to make sure there is nothing unexpected.
* Write a good pull request description:
* While there is no strict template that our contributors follow, we would like them to
sufficiently summarize and motivate the changes they are proposing. We recommend all pull requests,
at least indirectly, address the following points.
* Is this pull request important and why?
* Is it addressing an issue? If so, what issue? (provide links for convenience please)
* Is this a new feature? If so, why is it useful and/or necessary?
* Are there background references and documents that reviewers should be aware of to properly assess this change?
* Note: make sure to point out any design and architectural decisions that you made and the rationale behind them.
* Note: if you have been working with a specific user and would like them to review your work, make sure you mention them using (@<username>)
* Submit the pull request and iterate with feedback.
3. Merge and Release
* Getting approval:
* You will have to iterate on your changes with feedback from other collaborators to reach a point
where your pull request can be safely merged.
* To avoid too many comments on style and convention, make sure that you have a
look at our style section below before creating a pull request.
* Eventually, someone from the zstd team will approve your pull request and not long after merge it into
the dev branch.
* Housekeeping:
* Most PRs are linked with one or more Github issues. 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 <br> https://github.com/marketplace/travis-ci | `.travis.yml` |
| AppVeyor | Used for some Windows testing (e.g. cygwin, mingw) | https://www.appveyor.com/blog/2018/10/02/github-apps-integration/ <br> https://github.com/marketplace/appveyor | `appveyor.yml` |
| Cirrus CI | Used for testing on FreeBSD | https://github.com/marketplace/cirrus-ci/ | `.cirrus.yml` |
| Circle CI | Historically was used to provide faster signal,<br/> but we may be able to migrate these to Github Actions | https://circleci.com/docs/2.0/getting-started/#setting-up-circleci <br> https://youtu.be/Js3hMUsSZ2c <br> 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 <commit-before-your-change>
$ make && cp zstd zstd-old
$ git checkout <commit-after-your-change>
$ make && cp zstd zstd-new
$ zstd-old -i5 -b1 <your-test-data>
1<your-test-data> : 8990 -> 3992 (2.252), 302.6 MB/s , 626.4 MB/s
$ zstd-new -i5 -b1 <your-test-data>
1<your-test-data> : 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 <my-data> # 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 # <bench-program>` 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.

## 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 `<assert.h>`, `<stdlib.h>`, `<string.h>`,
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 `<stddef.h>` and `<limits.h>`.
- 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
## Coding Style
* 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

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.

## Build instructions
`make` is the officially maintained build system of this project.
All other build systems are "compatible" and 3rd-party maintained,
they may feature small differences in advanced options.
When your system allows it, prefer using `make` to build `zstd` and `libzstd`.
### Makefile
If your system is compatible with standard `make` (or `gmake`),
invoking `make` in root directory will generate `zstd` cli in root directory.
It will also create `libzstd` into `lib/`.
Other available options include:
- `make install` : create and install zstd cli, library and man pages
- `make check` : create and run `zstd`, test its behavior on local platform
The `Makefile` follows the [GNU Standard Makefile conventions](https://www.gnu.org/prep/standards/html_node/Makefile-Conventions.html),
allowing staged install, standard flags, directory variables and command variables.
For advanced use cases, specialized compilation flags which control binary generation
are documented in [`lib/README.md`](lib/README.md#modular-build) for the `libzstd` library
and in [`programs/README.md`](programs/README.md#compilation-variables) for the `zstd` CLI.

The zstd port in vcpkg is kept up to date by Microsoft team members and community contributors.
If the version is out of date, please [create an issue or pull request](https://github.com/Microsoft/vcpkg) on the vcpkg repository.

You can build the zstd binary via buck by executing: `buck build programs:zstd` from the root of the repo.
The output binary will be in `buck-out/gen/programs/`.
## Testing
You can run quick local smoke tests by running `make check`.
If you can't use `make`, execute the `playTest.sh` script from the `src/tests` directory.
Two env variables `$ZSTD_BIN` and `$DATAGEN_BIN` are needed for the test script to locate the `zstd` and `datagen` binary.
For information on CI testing, please refer to `TESTING.md`.

# Single File Zstandard Libraries
The script `combine.sh` creates an _amalgamated_ source file that can be used with or without `zstd.h`. This isn't a _header-only_ file but it does offer a similar level of simplicity when integrating into a project.
All it now takes to support Zstd in your own projects is the addition of a single file, two if using the header, with no configuration or further build steps.
Decompressor
------------
This is the most common use case. The decompression library is small, adding, for example, 26kB to an Emscripten compiled WebAssembly project. Native implementations add a little more, 40-70kB depending on the compiler and platform.
Create `zstddeclib.c` from the Zstd source using:
```
cd zstd/build/single_file_libs
python3 combine.py -r ../../lib -x legacy/zstd_legacy.h -o zstddeclib.c zstddeclib-in.c
```
Then add the resulting file to your project (see the [example files](examples)).
`create_single_file_decoder.sh` will run the above script, creating the file `zstddeclib.c` (`build_decoder_test.sh` will also create `zstddeclib.c`, then compile and test the result).
Full Library
------------
The same tool can amalgamate the entire Zstd library for ease of adding both compression and decompression to a project. The [roundtrip example](examples/roundtrip.c) uses the original `zstd.h` with the remaining source files combined into `zstd.c` (currently just over 1.2MB) created from `zstd-in.c`. As with the standalone decoder the most useful compile flags have already been rolled-in and the resulting file can be added to a project as-is.
Create `zstd.c` from the Zstd source using:
```
cd zstd/build/single_file_libs
python3 combine.py -r ../../lib -x legacy/zstd_legacy.h -k zstd.h -o zstd.c zstd-in.c
```
It's possible to create a compressor-only library but since the decompressor is so small in comparison this doesn't bring much of a gain (but for the curious, simply remove the files in the _decompress_ section at the end of `zstd-in.c`).
`create_single_file_library.sh` will run the script to create `zstd.c` (`build_library_test.sh` will also create `zstd.c`, then compile and test the result).

externalSequenceProducer
=====================
`externalSequenceProducer` is a test tool for the Block-Level Sequence Producer API.
It demonstrates how to use the API to perform a simple round-trip test.
A sample sequence producer is provided in sequence_producer.c, but the user can swap
this out with a different one if desired. The sample sequence producer implements
LZ parsing with a 1KB hashtable. Dictionary-based parsing is not currently supported.
Command line :
```
externalSequenceProducer filename
```

Subject: [PATCH v5 1/5] lib: Add xxhash module
Adds xxhash kernel module with xxh32 and xxh64 hashes. xxhash is an
extremely fast non-cryptographic hash algorithm for checksumming.
The zstd compression and decompression modules added in the next patch
require xxhash. I extracted it out from zstd since it is useful on its
own. I copied the code from the upstream XXHash source repository and
translated it into kernel style. I ran benchmarks and tests in the kernel
and tests in userland.
I benchmarked xxhash as a special character device. I ran in four modes,
no-op, xxh32, xxh64, and crc32. The no-op mode simply copies the data to
kernel space and ignores it. The xxh32, xxh64, and crc32 modes compute
hashes on the copied data. I also ran it with four different buffer sizes.
The benchmark file is located in the upstream zstd source repository under
`contrib/linux-kernel/xxhash_test.c` [1].
I ran the benchmarks on a Ubuntu 14.04 VM with 2 cores and 4 GiB of RAM.
The VM is running on a MacBook Pro with a 3.1 GHz Intel Core i7 processor,
16 GB of RAM, and a SSD. I benchmarked using the file `filesystem.squashfs`
from `ubuntu-16.10-desktop-amd64.iso`, which is 1,536,217,088 B large.
Run the following commands for the benchmark:
modprobe xxhash_test
mknod xxhash_test c 245 0
time cp filesystem.squashfs xxhash_test
The time is reported by the time of the userland `cp`.
The GB/s is computed with
1,536,217,008 B / time(buffer size, hash)
which includes the time to copy from userland.
The Normalized GB/s is computed with
1,536,217,088 B / (time(buffer size, hash) - time(buffer size, none)).
| Buffer Size (B) | Hash | Time (s) | GB/s | Adjusted GB/s |
|-----------------|-------|----------|------|---------------|
| 1024 | none | 0.408 | 3.77 | - |
| 1024 | xxh32 | 0.649 | 2.37 | 6.37 |
| 1024 | xxh64 | 0.542 | 2.83 | 11.46 |
| 1024 | crc32 | 1.290 | 1.19 | 1.74 |
| 4096 | none | 0.380 | 4.04 | - |
| 4096 | xxh32 | 0.645 | 2.38 | 5.79 |
| 4096 | xxh64 | 0.500 | 3.07 | 12.80 |
| 4096 | crc32 | 1.168 | 1.32 | 1.95 |
| 8192 | none | 0.351 | 4.38 | - |
| 8192 | xxh32 | 0.614 | 2.50 | 5.84 |
| 8192 | xxh64 | 0.464 | 3.31 | 13.60 |
| 8192 | crc32 | 1.163 | 1.32 | 1.89 |
| 16384 | none | 0.346 | 4.43 | - |
| 16384 | xxh32 | 0.590 | 2.60 | 6.30 |
| 16384 | xxh64 | 0.466 | 3.30 | 12.80 |
| 16384 | crc32 | 1.183 | 1.30 | 1.84 |
Tested in userland using the test-suite in the zstd repo under
`contrib/linux-kernel/test/XXHashUserlandTest.cpp` [2] by mocking the
kernel functions. A line in each branch of every function in `xxhash.c`
was commented out to ensure that the test-suite fails. Additionally
tested while testing zstd and with SMHasher [3].

Subject: [PATCH v5 3/5] btrfs: Add zstd support
Add zstd compression and decompression support to BtrFS. zstd at its
fastest level compresses almost as well as zlib, while offering much
faster compression and decompression, approaching lzo speeds.
I benchmarked btrfs with zstd compression against no compression, lzo
compression, and zlib compression. I benchmarked two scenarios. Copying
a set of files to btrfs, and then reading the files. Copying a tarball
to btrfs, extracting it to btrfs, and then reading the extracted files.
After every operation, I call `sync` and include the sync time.
Between every pair of operations I unmount and remount the filesystem
to avoid caching. The benchmark files can be found in the upstream
zstd source repository under
`contrib/linux-kernel/{btrfs-benchmark.sh,btrfs-extract-benchmark.sh}`
[1] [2].
I ran the benchmarks on a Ubuntu 14.04 VM with 2 cores and 4 GiB of RAM.
The VM is running on a MacBook Pro with a 3.1 GHz Intel Core i7 processor,
16 GB of RAM, and a SSD.
The first compression benchmark is copying 10 copies of the unzipped
Silesia corpus [3] into a BtrFS filesystem mounted with
`-o compress-force=Method`. The decompression benchmark times how long
it takes to `tar` all 10 copies into `/dev/null`. The compression ratio is
measured by comparing the output of `df` and `du`. See the benchmark file
[1] for details. I benchmarked multiple zstd compression levels, although
the patch uses zstd level 1.
| Method | Ratio | Compression MB/s | Decompression speed |
|---------|-------|------------------|---------------------|
| None | 0.99 | 504 | 686 |
| lzo | 1.66 | 398 | 442 |
| zlib | 2.58 | 65 | 241 |
| zstd 1 | 2.57 | 260 | 383 |
| zstd 3 | 2.71 | 174 | 408 |
| zstd 6 | 2.87 | 70 | 398 |
| zstd 9 | 2.92 | 43 | 406 |
| zstd 12 | 2.93 | 21 | 408 |
| zstd 15 | 3.01 | 11 | 354 |
The next benchmark first copies `linux-4.11.6.tar` [4] to btrfs. Then it
measures the compression ratio, extracts the tar, and deletes the tar.
Then it measures the compression ratio again, and `tar`s the extracted
files into `/dev/null`. See the benchmark file [2] for details.
| Method | Tar Ratio | Extract Ratio | Copy (s) | Extract (s)| Read (s) |
|--------|-----------|---------------|----------|------------|----------|
| None | 0.97 | 0.78 | 0.981 | 5.501 | 8.807 |
| lzo | 2.06 | 1.38 | 1.631 | 8.458 | 8.585 |
| zlib | 3.40 | 1.86 | 7.750 | 21.544 | 11.744 |
| zstd 1 | 3.57 | 1.85 | 2.579 | 11.479 | 9.389 |

Subject: [PATCH v5 4/5] squashfs: Add zstd support
Add zstd compression and decompression support to SquashFS. zstd is a
great fit for SquashFS because it can compress at ratios approaching xz,
while decompressing twice as fast as zlib. For SquashFS in particular,
it can decompress as fast as lzo and lz4. It also has the flexibility
to turn down the compression ratio for faster compression times.
The compression benchmark is run on the file tree from the SquashFS archive
found in ubuntu-16.10-desktop-amd64.iso [1]. It uses `mksquashfs` with the
default block size (128 KB) and and various compression algorithms/levels.
xz and zstd are also benchmarked with 256 KB blocks. The decompression
benchmark times how long it takes to `tar` the file tree into `/dev/null`.
See the benchmark file in the upstream zstd source repository located under
`contrib/linux-kernel/squashfs-benchmark.sh` [2] for details.
I ran the benchmarks on a Ubuntu 14.04 VM with 2 cores and 4 GiB of RAM.
The VM is running on a MacBook Pro with a 3.1 GHz Intel Core i7 processor,
16 GB of RAM, and a SSD.
| Method | Ratio | Compression MB/s | Decompression MB/s |
|----------------|-------|------------------|--------------------|
| gzip | 2.92 | 15 | 128 |
| lzo | 2.64 | 9.5 | 217 |
| lz4 | 2.12 | 94 | 218 |
| xz | 3.43 | 5.5 | 35 |
| xz 256 KB | 3.53 | 5.4 | 40 |
| zstd 1 | 2.71 | 96 | 210 |
| zstd 5 | 2.93 | 69 | 198 |

This patch was written by Sean Purcell <me@seanp.xyz>, but I will be

Date: Thu, 3 Aug 2017 17:47:03 -0700
Subject: [PATCH v6] squashfs-tools: Add zstd support
This patch adds zstd support to squashfs-tools. It works with zstd
versions >= 1.0.0. It was originally written by Sean Purcell.
Signed-off-by: Sean Purcell <me@seanp.xyz>
Signed-off-by: Nick Terrell <terrelln@fb.com>

v4 -> v5:
- Fix patch documentation to reflect that Sean Purcell is the author
- Don't strip trailing whitespace of unrelated code
- Make zstd_display_options() static
v5 -> v6:
- Fix build instructions in Makefile

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Lesser General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License along
with this program; if not, write to the Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 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. If this is what you want to do, use the GNU Lesser General
Public License instead of this License.

# Zstd in the Linux Kernel
# Linux Kernel Patch
This directory contains the scripts needed to transform upstream zstd into the version imported into the kernel. All the transforms are automated and tested by our continuous integration.
There are four pieces, the `xxhash` kernel module, the `zstd_compress` and `zstd_decompress` kernel modules, the BtrFS patch, and the SquashFS patch.
The patches are based off of the linux kernel master branch.
## Upgrading Zstd in the Linux Kernel
## xxHash kernel module
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.
* The patch is located in `xxhash.diff`.
* The header is in `include/linux/xxhash.h`.
* The source is in `lib/xxhash.c`.
* `test/XXHashUserLandTest.cpp` contains tests for the patch in userland by mocking the kernel headers.
I tested the tests by commenting a line of of each branch in `xxhash.c` one line at a time, and made sure the tests failed.
It can be run with the following commands:
```
cd test && make googletest && make XXHashUserLandTest && ./XXHashUserLandTest
```
* I also benchmarked the `xxhash` module against upstream xxHash, and made sure that they ran at the same speed.
## Zstd Kernel modules
* The (large) patch is located in `zstd.diff`, which depends on `xxhash.diff`.
* The header is in `include/linux/zstd.h`.
* It is split up into `zstd_compress` and `zstd_decompress`, which can be loaded independently.
* Source files are in `lib/zstd/`.
* `lib/Kconfig` and `lib/Makefile` need to be modified by applying `lib/Kconfig.diff` and `lib/Makefile.diff` respectively.
These changes are also included in the `zstd.diff`.
* `test/UserlandTest.cpp` contains tests for the patch in userland by mocking the kernel headers.
It can be run with the following commands:
```
cd test && make googletest && make UserlandTest && ./UserlandTest
```
## BtrFS
* The patch is located in `btrfs.diff`.
* Additionally `fs/btrfs/zstd.c` is provided as a source for convenience.
* The patch seems to be working, it doesn't crash the kernel, and compresses at speeds and ratios that are expected.
It could still use some more testing for fringe features, like printing options.
### Benchmarks
Benchmarks run on a Ubuntu 14.04 with 2 cores and 4 GiB of RAM.
The VM is running on a Macbook Pro with a 3.1 GHz Intel Core i7 processor,
16 GB of ram, and a SSD.
The kernel running was built from the master branch with the patch.
The compression benchmark is copying 10 copies of the
unzipped [silesia corpus](http://mattmahoney.net/dc/silesia.html) into a BtrFS
filesystem mounted with `-o compress-force={none, lzo, zlib, zstd}`.
The decompression benchmark is timing how long it takes to `tar` all 10 copies
into `/dev/null`.
The compression ratio is measured by comparing the output of `df` and `du`.
See `btrfs-benchmark.sh` for details.
| Algorithm | Compression ratio | Compression speed | Decompression speed |
|-----------|-------------------|-------------------|---------------------|
| None | 0.99 | 504 MB/s | 686 MB/s |
| lzo | 1.66 | 398 MB/s | 442 MB/s |
| zlib | 2.58 | 65 MB/s | 241 MB/s |
| zstd 1 | 2.57 | 260 MB/s | 383 MB/s |
| zstd 3 | 2.71 | 174 MB/s | 408 MB/s |
| zstd 6 | 2.87 | 70 MB/s | 398 MB/s |
| zstd 9 | 2.92 | 43 MB/s | 406 MB/s |
| zstd 12 | 2.93 | 21 MB/s | 408 MB/s |
| zstd 15 | 3.01 | 11 MB/s | 354 MB/s |
## SquashFS
* The patch is located in `squashfs.diff`
* Additionally `fs/squashfs/zstd_wrapper.c` is provided as a source for convenience.
* The patch has been tested on the master branch of the kernel.
### Benchmarks
Benchmarks run on a Ubuntu 14.04 with 2 cores and 4 GiB of RAM.
The VM is running on a Macbook Pro with a 3.1 GHz Intel Core i7 processor,
16 GB of ram, and a SSD.
The kernel running was built from the master branch with the patch.
The compression benchmark is the file tree from the SquashFS archive found in the
Ubuntu 16.10 desktop image (ubuntu-16.10-desktop-amd64.iso).
The compression benchmark uses mksquashfs with the default block size (128 KB)
and various compression algorithms/compression levels.
`xz` and `zstd` are also benchmarked with 256 KB blocks.
The decompression benchmark is timing how long it takes to `tar` the file tree
into `/dev/null`.
See `squashfs-benchmark.sh` for details.
| Algorithm | Compression ratio | Compression speed | Decompression speed |
|----------------|-------------------|-------------------|---------------------|
| gzip | 2.92 | 15 MB/s | 128 MB/s |
| lzo | 2.64 | 9.5 MB/s | 217 MB/s |
| lz4 | 2.12 | 94 MB/s | 218 MB/s |
| xz | 3.43 | 5.5 MB/s | 35 MB/s |
| xz 256 KB | 3.53 | 5.4 MB/s | 40 MB/s |
| zstd 1 | 2.71 | 96 MB/s | 210 MB/s |
| zstd 5 | 2.93 | 69 MB/s | 198 MB/s |
| zstd 10 | 3.01 | 41 MB/s | 225 MB/s |
| zstd 15 | 3.13 | 11.4 MB/s | 224 MB/s |
| zstd 16 256 KB | 3.24 | 8.1 MB/s | 210 MB/s |
