|
||
*First of all, thank you for taking the time to contribute!*
|
||
|
||
By using the following guidelines, you can help us make ZFS on Linux even
|
||
better.

||
## What should I know before I get started?
|
||
|
||
### Get ZFS
|
||
You can build zfs packages by following [these
|
||
instructions](https://github.com/zfsonlinux/zfs/wiki/Building-ZFS),
|
||
or install stable packages from [your distribution's
|
||
repository](https://github.com/zfsonlinux/zfs/wiki/Getting-Started).
|
||
|
||
### Debug ZFS
|
||
A variety of methods and tools are available to aid ZFS developers.
|
||
It's strongly recommended that when developing a patch the `--enable-debug`
|
||
configure option should be set. This will enable additional correctness
|
||
checks and all the ASSERTs to help quickly catch potential issues.
|
||
|
||
In addition, there are numerous utilities and debugging files which
|
||
provide visibility in to the inner workings of ZFS. The most useful
|
||
of these tools are discussed in detail on the [debugging ZFS wiki
|
||
page](https://github.com/zfsonlinux/zfs/wiki/Debugging).
|
||
|
||
### Where can I ask for help?
|
||
The [mailing list](https://github.com/zfsonlinux/zfs/wiki/Mailing-Lists)
|
||
is the best place to ask for help.
|
||
|
||
## How Can I Contribute?
|
||
|
||
### Reporting Bugs
|
||
*Please* contact us via the [mailing
|
||
list](https://github.com/zfsonlinux/zfs/wiki/Mailing-Lists) if you aren't
|
||
certain that you are experiencing a bug.
|
||
|
||
If you run into an issue, please search our [issue
|
||
tracker](https://github.com/zfsonlinux/zfs/issues) *first* to ensure the
|
||
issue hasn't been reported before. Open a new issue only if you haven't
|
||
found anything similar to your issue.
|
||
|
||
You can open a new issue and search existing issues using the public [issue
|
||
tracker](https://github.com/zfsonlinux/zfs/issues).
|
||
|
||
#### When opening a new issue, please include the following information at the top of the issue:
|
||
* What distribution (with version) you are using.
|
||
* The spl and zfs versions you are using, installation method (repository
|
||
or manual compilation).
|
||
* Describe the issue you are experiencing.
|
||
* Describe how to reproduce the issue.
|
||
* Including any warning/errors/backtraces from the system logs.
|
||
|
||
When a new issue is opened, it is not uncommon for developers to request
|
||
additional information.
|
||
|
||
In general, the more detail you share about a problem the quicker a
|
||
developer can resolve it. For example, providing a simple test case is always
|
||
exceptionally helpful.
|
||
|
||
Be prepared to work with the developers investigating your issue. Your
|
||
assistance is crucial in providing a quick solution. They may ask for
|
||
information like:
|
||
|
||
* Your pool configuration as reported by `zdb` or `zpool status`.
|
||
* Your hardware configuration, such as
|
||
* Number of CPUs.
|
||
* Amount of memory.
|
||
* Whether your system has ECC memory.
|
||
* Whether it is running under a VMM/Hypervisor.
|
||
* Kernel version.
|
||
* Values of the spl/zfs module parameters.
|
||
* Stack traces which may be logged to `dmesg`.
|
||
|
||
### Suggesting Enhancements
|
||
ZFS on Linux is a widely deployed production filesystem which is under
|
||
active development. The team's primary focus is on fixing known issues,
|
||
improving performance, and adding compelling new features.
|
||
|
||
You can view the list of proposed features
|
||
by filtering the issue tracker by the ["Feature"
|
||
label](https://github.com/zfsonlinux/zfs/issues?q=is%3Aopen+is%3Aissue+label%3AFeature).
|
||
If you have an idea for a feature first check this list. If your idea already
|
||
appears then add a +1 to the top most comment, this helps us gauge interest
|
||
in that feature.
|
||
|
||
Otherwise, open a new issue and describe your proposed feature. Why is this
|
||
feature needed? What problem does it solve?
|
||
|
||
### Pull Requests
|
||
* All pull requests must be based on the current master branch and apply
|
||
without conflicts.
|
||
* Please attempt to limit pull requests to a single commit which resolves
|
||
one specific issue.
|
||
* When updating a pull request squash multiple commits by performing a
|
||
[rebase](https://git-scm.com/docs/git-rebase) (squash).
|
||
* For large pull requests consider structuring your changes as a stack of
|
||
logically independent patches which build on each other. This makes large
|
||
changes easier to review and approve which speeds up the merging process.
|
||
* Try to keep pull requests simple. Simple code with comments is much easier
|
||
to review and approve.
|
||
* Test cases should be provided when appropriate.
|
||
* If your pull request improves performance, please include some benchmarks.
|
||
* The pull request must pass all required [ZFS
|
||
Buildbot](http://build.zfsonlinux.org/) builders before
|
||
being accepted. If you are experiencing intermittent TEST
|
||
builder failures, you may be experiencing a [test suite
|
||
issue](https://github.com/zfsonlinux/zfs/issues?q=is%3Aissue+is%3Aopen+label%3A%22Test+Suite%22).
|
||
* All proposed changes must be approved by a ZFS on Linux organization member.
|
||
|
||
### Testing
|
||
All help is appreciated! If you're in a position to run the latest code
|
||
consider helping us by reporting any functional problems, performance
|
||
regressions or other suspected issues. By running the latest code to a wide
|
||
range of realistic workloads, configurations and architectures we're better
|
||
able quickly identify and resolve potential issues.
|
||
|
||
Users can also run the [ZFS Test
|
||
Suite](https://github.com/zfsonlinux/zfs/tree/master/tests) on their systems
|
||
to verify ZFS is behaving as intended.
|
||
|
||
## Style Guides
|
||
|
||
### Coding Conventions
|
||
We currently use [C Style and Coding Standards for
|
||
SunOS](http://www.cis.upenn.edu/%7Elee/06cse480/data/cstyle.ms.pdf) as our
|
||
coding convention.
