# 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>
## Issues
We use GitHub issues to track public bugs. Please ensure your description is
clear and has sufficient instructions to be able to reproduce the issue.
Facebook has a [bounty program](https://www.facebook.com/whitehat/) for the safe
disclosure of security bugs. In those cases, please go through the process
outlined on that page and do not file a public issue.
## Coding Style

Additional Grant of Patent Rights Version 2
"Software" means the Zstandard software distributed by Facebook, Inc.
Facebook, Inc. ("Facebook") hereby grants to each recipient of the Software
("you") a perpetual, worldwide, royalty-free, non-exclusive, irrevocable
(subject to the termination provision below) license under any Necessary
Claims, to make, have made, use, sell, offer to sell, import, and otherwise
transfer the Software. For avoidance of doubt, no license is granted under
Facebook’s rights in any patent claims that are infringed by (i) modifications
to the Software made by you or any third party or (ii) the Software in
combination with any software or other technology.
The license granted hereunder will terminate, automatically and without notice,
if you (or any of your subsidiaries, corporate affiliates or agents) initiate
directly or indirectly, or take a direct financial interest in, any Patent
Assertion: (i) against Facebook or any of its subsidiaries or corporate
affiliates, (ii) against any party if such Patent Assertion arises in whole or
in part from any software, technology, product or service of Facebook or any of
its subsidiaries or corporate affiliates, or (iii) against any party relating
to the Software. Notwithstanding the foregoing, if Facebook or any of its
subsidiaries or corporate affiliates files a lawsuit alleging patent
infringement against you in the first instance, and you respond by filing a
patent infringement counterclaim in that lawsuit against that party that is
unrelated to the Software, the license granted hereunder will not terminate
under section (i) of this paragraph due to such counterclaim.
A "Necessary Claim" is a claim of a patent owned by Facebook that is
necessarily infringed by the Software standing alone.
A "Patent Assertion" is any lawsuit or other action alleging direct, indirect,
or contributory infringement or inducement to infringe any patent, including a
cross-claim or counterclaim.

### Status ### Status
Zstd compression format has reached "Final status". It means it is planned to become the official stable zstd format tagged `v1.0`. The reason it's not yet tagged `v1.0` is that it currently performs its "validation period", making sure the format holds all its promises and nothing was missed. Zstandard is currently deployed within Facebook. It is used daily to compress and decompress very large amount of data in multiple formats and use cases.
Zstd library also offers legacy decoder support. Any data compressed by any version >= `v0.1` is decodable now and in the future. Zstandard is considered safe for production environments.
The library has been validated using strong [fuzzer tests](https://en.wikipedia.org/wiki/Fuzz_testing), including both [internal tools](programs/fuzzer.c) and [external ones](http://lcamtuf.coredump.cx/afl). It's able to withstand hazard situations, including invalid inputs.
As a consequence, Zstandard is considered safe for, and is currently used in, production environments.
### Branch Policy ### License
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. Zstandard is [BSD-licensed](LICENSE). We also provide an [additional patent grant](PATENTS).
### Contributing
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.
