# Contributing to Zstandard
We want to make contributing to this project as easy and transparent as
possible.
## Our Development Process
New versions are being developed in the "dev" branch,
or in their own feature branch.
When they are deemed ready for a release, they are merged into "master".
As a consequences, all contributions must stage first through "dev"
or their own feature branch.
## Pull Requests
We actively welcome your pull requests.
1. Fork the repo and create your branch from `dev`.
2. If you've added code that should be tested, add tests.
3. If you've changed APIs, update the documentation.
4. Ensure the test suite passes.
5. Make sure your code lints.
6. If you haven't already, complete the Contributor License Agreement ("CLA").
## Contributor License Agreement ("CLA")
In order to accept your pull request, we need you to submit a CLA. You only need
to do this once to work on any of Facebook's open source projects.
Complete your CLA here: <https://code.facebook.com/cla>
## 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
* Update:
* 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 consise 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, make sure that all CI tests pass on your local fork.
See our section on setting up your CI environment for more information on how to do this.
* 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 contributers 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 :
+ torteous 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 kind of reports can be useful, and are accepted.
## 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 adding 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 asses 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 optimzing 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 snippit is only part of a function, it might be worth trying to
isolate that snippit by moving it to its own function (this is usually not necessary but
might be).
Most profilers (including the profilers dicusssed below) will generate a call graph of
functions for you. Your goal will be to find your function of interest in this call grapch
and then inspect the time spent inside of it. You might also want to 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 bencharmking 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 labled
`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 bencharking 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 scripg 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 handware
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
## Setting up continuous integration (CI) on your fork
Zstd uses a number of different continuous integration (CI) tools to ensure that new changes
are well tested before they make it to an official release. Specifically, we use the platforms
travis-ci, circle-ci, and appveyor.
Changes cannot be merged into the main dev branch unless they pass all of our CI tests.
The easiest way to run these CI tests on your own before submitting a PR to our dev branch
is to configure your personal fork of zstd with each of the CI platforms. Below, you'll find
instructions for doing this.
### travis-ci
Follow these steps to link travis-ci with your github fork of zstd
1. Make sure you are logged into your github account
2. Go to https://travis-ci.org/
3. Click 'Sign in with Github' on the top right
4. Click 'Authorize travis-ci'
5. Click 'Activate all repositories using Github Apps'
6. Select 'Only select repositories' and select your fork of zstd from the drop down
7. Click 'Approve and Install'
8. Click 'Sign in with Github' again. This time, it will be for travis-pro (which will let you view your tests on the web dashboard)
9. Click 'Authorize travis-pro'
10. You should have travis set up on your fork now.
### circle-ci
TODO
### appveyor
Follow these steps to link circle-ci with your girhub fork of zstd
1. Make sure you are logged into your github account
2. Go to https://www.appveyor.com/
3. Click 'Sign in' on the top right
4. Select 'Github' on the left panel
5. Click 'Authorize appveyor'
6. You might be asked to select which repositories you want to give appveyor permission to. Select your fork of zstd if you're prompted
7. You should have appveyor set up on your fork now.
### General notes on CI
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 master 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.
## 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.

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**, short for Zstandard, is a fast lossless compression algorithm, targeting real-time compression scenarios at zlib-level compression ratio.
__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).
It is provided as a BSD-license package, hosted on Github.
The project is 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](http://www.zstd.net/#other-languages).

The negative compression levels, specified with `--fast=#`,
offer faster compression and decompression speed in exchange for some loss in
compression ratio compared to level 1, as seen in the table above.
Zstd can also offer stronger compression ratio at the cost of compression speed.
Speed vs Compression trade-off is configurable by small increment. Decompression speed is preserved and remain roughly the same at all settings, a property shared by most LZ compression algorithms, such as [zlib].

## The case for Small Data compression
### 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.
Previous charts provide results applicable to typical files and streams scenarios (several MB). Small data come with different perspectives. The smaller the amount of data to compress, the more difficult it is to achieve any significant compression.
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.
This problem is common to any compression algorithm. The reason is, compression algorithms learn from past data how to compress future data. But at the beginning of a new file, 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 result of the training is stored in a file called "dictionary", which can 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.
![Compressing Small Data](images/smallData.png "Compressing Small Data")
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.
Dictionary work if there is some correlation in a family of small data (there is no _universal dictionary_).
Hence, deploying one dictionary per type of data will provide the greater benefits. Dictionary gains are mostly effective in the first few KB. Then, the compression algorithm will rely more and more on previously decoded content to compress the rest of the file.
These compression gains are achieved while simultaneously providing _faster_ compression and decompression speeds.
#### Dictionary compression How To :
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. Then, the compression algorithm will gradually use previously decoded content to better compress the rest of the file.
##### _Using the Command Line Utility_ :
### Dictionary compression How To:
1) Create the dictionary
1. Create the dictionary
`zstd --train FullPathToTrainingSet/* -o dictionaryName`
`zstd --train FullPathToTrainingSet/* -o dictionaryName`
2) Compress with dictionary
2. Compress with dictionary
`zstd FILE -D dictionaryName`
`zstd -D dictionaryName FILE`
3) Decompress with dictionary
3. Decompress with dictionary
`zstd --decompress FILE.zst -D dictionaryName`
`zstd -D dictionaryName --decompress FILE.zst`
### Status
Zstd is in development. The internal format evolves to reach better performance. "Final Format" is projected H1 2016, and will be tagged `v1.0`. Zstd offers legacy support, meaning any data compressed by any version >= 0.1 (therefore including current one) remain decodable in the future.
The library is also quite robust, able to withstand hazards situations, including invalid inputs. Library reliability has been tested using [Fuzz Testing](https://en.wikipedia.org/wiki/Fuzz_testing), with both [internal tools](programs/fuzzer.c) and [external ones](http://lcamtuf.coredump.cx/afl). Therefore, Zstandard is considered safe for production environments.
## Build instructions
### Branch Policy
### Makefile
The "dev" branch is the one where all contributions will be merged before reaching "master". If you plan to propose a patch, please commit into the "dev" branch or its own feature branch. Direct commit to "master" are not permitted.
If your system is compatible with standard `make` (or `gmake`),
invoking `make` in root directory will generate `zstd` cli in root directory.
### Miscellaneous
Other available options include:
- `make install` : create and install zstd cli, library and man pages
- `make check` : create and run `zstd`, tests its behavior on local platform
### cmake
A `cmake` project generator is provided within `build/cmake`.
It can generate Makefiles or other build scripts
to create `zstd` binary, and `libzstd` dynamic and static libraries.
By default, `CMAKE_BUILD_TYPE` is set to `Release`.
### Meson
A Meson project is provided within [`build/meson`](build/meson). Follow
build instructions in that directory.
You can also take a look at [`.travis.yml`](.travis.yml) file for an
example about how Meson is used to build this project.
Note that default build type is **release**.
### VCPKG
You can build and install zstd [vcpkg](https://github.com/Microsoft/vcpkg/) dependency manager:
git clone https://github.com/Microsoft/vcpkg.git
cd vcpkg
./bootstrap-vcpkg.sh
./vcpkg integrate install
./vcpkg install zstd
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.
### Visual Studio (Windows)
Going into `build` directory, you will find additional possibilities:
- Projects for Visual Studio 2005, 2008 and 2010.
+ VS2010 project is compatible with VS2012, VS2013, VS2015 and VS2017.
- Automated build scripts for Visual compiler by [@KrzysFR](https://github.com/KrzysFR), in `build/VS_scripts`,
which will build `zstd` cli and `libzstd` library without any need to open Visual Studio solution.
### Buck
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 executing 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
## Status
Zstandard is currently deployed within Facebook. It is used continuously to compress large amounts of data in multiple formats and use cases.
Zstandard is considered safe for production environments.
## License
Zstandard is dual-licensed under [BSD](LICENSE) and [GPLv2](COPYING).
## Contributing
The "dev" branch is the one where all contributions are merged before reaching "master".

Testing
=======
Zstandard CI testing is split up into three sections:
short, medium, and long tests.
Short Tests
-----------
Short tests run on CircleCI for new commits on every branch and pull request.
They consist of the following tests:
- Compilation on all supported targets (x86, x86_64, ARM, AArch64, PowerPC, and PowerPC64)
- Compilation on various versions of gcc, clang, and g++
- `tests/playTests.sh` on x86_64, without the tests on long data (CLI tests)
- Small tests (`tests/legacy.c`, `tests/longmatch.c`) on x64_64
Medium Tests
------------
Medium tests run on every commit and pull request to `dev` branch, on TravisCI.
They consist of the following tests:
- The following tests run with UBsan and Asan on x86_64 and x86, as well as with
Msan on x86_64
- `tests/playTests.sh --test-large-data`
- Fuzzer tests: `tests/fuzzer.c`, `tests/zstreamtest.c`, and `tests/decodecorpus.c`
- `tests/zstreamtest.c` under Tsan (streaming mode, including multithreaded mode)
- Valgrind Test (`make -C tests valgrindTest`) (testing CLI and fuzzer under valgrind)
- Fuzzer tests (see above) on ARM, AArch64, PowerPC, and PowerPC64
Long Tests
----------
Long tests run on all commits to `master` branch,
and once a day on the current version of `dev` branch,
on TravisCI.
They consist of the following tests:
- Entire test suite (including fuzzers and some other specialized tests) on:
- x86_64 and x86 with UBsan and Asan
- x86_64 with Msan
- ARM, AArch64, PowerPC, and PowerPC64
- Streaming mode fuzzer with Tsan (for the `zstdmt` testing)
- ZlibWrapper tests, including under valgrind
- Versions test (ensuring `zstd` can decode files from all previous versions)
- `pzstd` with asan and tsan, as well as in 32-bits mode
- Testing `zstd` with legacy mode off
- Testing `zbuff` (old streaming API)
- Entire test suite and make install on macOS

Projects for various integrated development environments (IDE)
==============================================================
#### Included projects
The following projects are included with the zstd distribution:
- `cmake` - CMake project contributed by Artyom Dymchenko
- `VS2005` - Visual Studio 2005 Project (this project has been moved to the contrib directory and will no longer be supported)
- `VS2008` - Visual Studio 2008 project
- `VS2010` - Visual Studio 2010 project (which also works well with Visual Studio 2012, 2013, 2015)
- `VS_scripts` - command line scripts prepared for Visual Studio compilation without IDE
#### How to compile zstd with Visual Studio
1. Install Visual Studio e.g. VS 2015 Community Edition (it's free).
2. Download the latest version of zstd from https://github.com/facebook/zstd/releases
3. Decompress ZIP archive.
4. Go to decompressed directory then to `projects` then `VS2010` and open `zstd.sln`
5. Visual Studio will ask about converting VS2010 project to VS2015 and you should agree.
6. Change `Debug` to `Release` and if you have 64-bit Windows change also `Win32` to `x64`.
7. Press F7 on keyboard or select `BUILD` from the menu bar and choose `Build Solution`.
8. If compilation will be fine a compiled executable will be in `projects\VS2010\bin\x64\Release\zstd.exe`
#### Projects available within zstd.sln
The Visual Studio solution file `visual\VS2010\zstd.sln` contains many projects that will be compiled to the
`visual\VS2010\bin\$(Platform)_$(Configuration)` directory. For example `zstd` set to `x64` and
`Release` will be compiled to `visual\VS2010\bin\x64_Release\zstd.exe`. The solution file contains the
following projects:
- `zstd` : Command Line Utility, supporting gzip-like arguments
- `datagen` : Synthetic and parametrable data generator, for tests
- `fullbench` : Precisely measure speed for each zstd inner functions
- `fuzzer` : Test tool, to check zstd integrity on target platform
- `libzstd` : A static ZSTD library compiled to `libzstd_static.lib`
- `libzstd-dll` : A dynamic ZSTD library (DLL) compiled to `libzstd.dll` with the import library `libzstd.lib`
- `fullbench-dll` : The fullbench program compiled with the import library; the executable requires ZSTD DLL
#### Using ZSTD DLL with Microsoft Visual C++ project
The header file `lib\zstd.h` and the import library
`visual\VS2010\bin\$(Platform)_$(Configuration)\libzstd.lib` are required to compile
a project using Visual C++.
1. The path to header files should be added to `Additional Include Directories` that can
be found in Project Properties of Visual Studio IDE in the `C/C++` Property Pages on the `General` page.
2. The import library has to be added to `Additional Dependencies` that can
be found in Project Properties in the `Linker` Property Pages on the `Input` page.
If one will provide only the name `libzstd.lib` without a full path to the library
then the directory has to be added to `Linker\General\Additional Library Directories`.
The compiled executable will require ZSTD DLL which is available at
`visual\VS2010\bin\$(Platform)_$(Configuration)\libzstd.dll`.

Command line scripts for Visual Studio compilation without IDE
==============================================================
Here are a few command lines for reference :
### Build with Visual Studio 2013 for msvcr120.dll
Running the following command will build both the `Release Win32` and `Release x64` versions:
```batch
build.VS2013.cmd
```
The result of each build will be in the corresponding `bin\Release\{ARCH}\` folder.
If you want to only need one architecture:
- Win32: `build.generic.cmd VS2013 Win32 Release v120`
- x64: `build.generic.cmd VS2013 x64 Release v120`
If you want a Debug build:
- Win32: `build.generic.cmd VS2013 Win32 Debug v120`
- x64: `build.generic.cmd VS2013 x64 Debug v120`
### Build with Visual Studio 2015 for msvcr140.dll
Running the following command will build both the `Release Win32` and `Release x64` versions:
```batch
build.VS2015.cmd
```
The result of each build will be in the corresponding `bin\Release\{ARCH}\` folder.
If you want to only need one architecture:
- Win32: `build.generic.cmd VS2015 Win32 Release v140`
- x64: `build.generic.cmd VS2015 x64 Release v140`
If you want a Debug build:
- Win32: `build.generic.cmd VS2015 Win32 Debug v140`
- x64: `build.generic.cmd VS2015 x64 Debug v140`
### Build with Visual Studio 2015 for msvcr120.dll
This capability is offered through `build.generic.cmd` using proper arguments:
**For Win32**
```batch
build.generic.cmd VS2015 Win32 Release v120
```
The result of the build will be in the `bin\Release\Win32\` folder.
**For x64**
```batch
build.generic.cmd VS2015 x64 Release v120
```
The result of the build will be in the `bin\Release\x64\` folder.
If you want Debug builds, replace `Release` with `Debug`.
### Build with Visual Studio 2017
`build.VS2017.cmd`, contributed by [@HaydnTrigg](https://github.com/HaydnTrigg),
will build both the `Release Win32` and `Release x64` versions
of the first VS2017 variant it finds, in this priority order :
Enterprise > Professional > Community
Alternatively, it's possible to target a specific version,
using appropriate script, such as `build.VS2017Enterprise.cmd` for example.

# Cmake contributions
Contributions to the cmake build configurations are welcome. Please
use case sensitivity that matches modern (ie. cmake version 2.6 and above)
conventions of using lower-case for commands, and upper-case for
variables.
## How to build
As cmake doesn't support command like `cmake clean`, it's recommended to perform a "out of source build".
To do this, you can create a new directory and build in it:
```sh
cd build/cmake
mkdir builddir
cd builddir
cmake ..
make
```
Then you can clean all cmake caches by simply delete the new directory:
```sh
rm -rf build/cmake/builddir
```
And of course, you can directly build in build/cmake:
```sh
cd build/cmake
cmake
make
```
To show cmake build options, you can:
```sh
cd build/cmake/builddir
cmake -LH ..
```
Bool options can be set to `ON/OFF` with `-D[option]=[ON/OFF]`. You can configure cmake options like this:
```sh
cd build/cmake/builddir
cmake -DZSTD_BUILD_TESTS=ON -DZSTD_LEGACY_SUPPORT=ON ..
make
```
### referring
[Looking for a 'cmake clean' command to clear up CMake output](https://stackoverflow.com/questions/9680420/looking-for-a-cmake-clean-command-to-clear-up-cmake-output)
## CMake Style Recommendations
### Indent all code correctly, i.e. the body of
* if/else/endif
* foreach/endforeach
* while/endwhile
* macro/endmacro
* function/endfunction
Use spaces for indenting, 2, 3 or 4 spaces preferably. Use the same amount of
spaces for indenting as is used in the rest of the file. Do not use tabs.
### Upper/lower casing
Most important: use consistent upper- or lowercasing within one file !
In general, the all-lowercase style is preferred.
So, this is recommended:
```
add_executable(foo foo.c)
```
These forms are discouraged
```
ADD_EXECUTABLE(bar bar.c)
Add_Executable(hello hello.c)
aDd_ExEcUtAbLe(blub blub.c)
```
### End commands
To make the code easier to read, use empty commands for endforeach(), endif(),
endfunction(), endmacro() and endwhile(). Also, use empty else() commands.
For example, do this:
```
if(FOOVAR)
some_command(...)
else()
another_command(...)
endif()
```
and not this:
```
if(BARVAR)
some_other_command(...)
endif(BARVAR)
```

Meson build system for zstandard
================================
Meson is a build system designed to optimize programmer productivity.
It aims to do this by providing simple, out-of-the-box support for
modern software development tools and practices, such as unit tests,
coverage reports, Valgrind, CCache and the like.
This Meson build system is provided with no guarantee and maintained
by Dima Krasner \<dima@dimakrasner.com\>.
It outputs one `libzstd`, either shared or static, depending on
`default_library` option.
## How to build
`cd` to this meson directory (`build/meson`)
```sh
meson setup -Dbin_programs=true -Dbin_contrib=true builddir
cd builddir
ninja # to build
ninja install # to install
```
You might want to install it in staging directory:
```sh
DESTDIR=./staging ninja install
```
To configure build options, use:
```sh
meson configure
```
See [man meson(1)](https://manpages.debian.org/testing/meson/meson.1.en.html).

gen_html - a program for automatic generation of zstd manual
============================================================
#### Introduction
This simple C++ program generates a single-page HTML manual from `zstd.h`.
The format of recognized comment blocks is following:
- comments of type `/*!` mean: this is a function declaration; switch comments with declarations
- comments of type `/**` and `/*-` mean: this is a comment; use a `<H2>` header for the first line
- comments of type `/*=` and `/**=` mean: use a `<H3>` 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
```

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 :
-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)
--nbDicts=# : set nb of dictionaries to # (default: one per block)
-h : help (this text)
```
