build: move e2e dependencies into e2e/go.mod
Several packages are only used while running the e2e suite. These packages are less important to update, as the they can not influence the final executable that is part of the Ceph-CSI container-image. By moving these dependencies out of the main Ceph-CSI go.mod, it is easier to identify if a reported CVE affects Ceph-CSI, or only the testing (like most of the Kubernetes CVEs).

## How to Contribute ##
|
||||
|
||||
We always welcome contributions to help make `go-zfs` better. Please take a moment to read this document if you would like to contribute.
|
||||
|
||||
### Reporting issues ###
|
||||
|
||||
We use [Github issues](https://github.com/mistifyio/go-zfs/issues) to track bug reports, feature requests, and submitting pull requests.
|
||||
|
||||
If you find a bug:
|
||||
|
||||
* Use the GitHub issue search to check whether the bug has already been reported.
|
||||
* If the issue has been fixed, try to reproduce the issue using the latest `master` branch of the repository.
|
||||
* If the issue still reproduces or has not yet been reported, try to isolate the problem before opening an issue, if possible. Also provide the steps taken to reproduce the bug.
|
||||
|
||||
### Pull requests ###
|
||||
|
||||
We welcome bug fixes, improvements, and new features. Before embarking on making significant changes, please open an issue and ask first so that you do not risk duplicating efforts or spending time working on something that may be out of scope. For minor items, just open a pull request.
|
||||
|
||||
[Fork the project](https://help.github.com/articles/fork-a-repo), clone your fork, and add the upstream to your remote:
|
||||
|
||||
$ git clone git@github.com:<your-username>/go-zfs.git
|
||||
$ cd go-zfs
|
||||
$ git remote add upstream https://github.com/mistifyio/go-zfs.git
|
||||
|
||||
If you need to pull new changes committed upstream:
|
||||
|
||||
$ git checkout master
|
||||
$ git fetch upstream
|
||||
$ git merge upstream/master
|
||||
|
||||
Don' work directly on master as this makes it harder to merge later. Create a feature branch for your fix or new feature:
|
||||
|
||||
$ git checkout -b <feature-branch-name>
|
||||
|
||||
Please try to commit your changes in logical chunks. Ideally, you should include the issue number in the commit message.
|
||||
|
||||
$ git commit -m "Issue #<issue-number> - <commit-message>"
|
||||
|
||||
Push your feature branch to your fork.
|
||||
|
||||
$ git push origin <feature-branch-name>
|
||||
|
||||
[Open a Pull Request](https://help.github.com/articles/using-pull-requests) against the upstream master branch. Please give your pull request a clear title and description and note which issue(s) your pull request fixes.
|
||||
|
||||
* All Go code should be formatted using [gofmt](http://golang.org/cmd/gofmt/).
|
||||
* Every exported function should have [documentation](http://blog.golang.org/godoc-documenting-go-code) and corresponding [tests](http://golang.org/doc/code.html#Testing).
|
||||
|
||||
**Important:** By submitting a patch, you agree to allow the project owners to license your work under the [Apache 2.0 License](./LICENSE).
|
||||
|
||||
### Go Tools ###
|
||||
For consistency and to catch minor issues for all of go code, please run the following:
|
||||
* goimports
|
||||
* go vet
|
||||
* golint
|
||||
* errcheck
|
||||
|
||||
Many editors can execute the above on save.

|
||||
copyright notice that is included in or attached to the work
|
||||
(an example is provided in the Appendix below).
|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain
|
||||
separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.
|
||||
|
||||
"Contribution" shall mean any work of authorship, including
|
||||
the original version of the Work and any modifications or additions
|
||||
to that Work or Derivative Works thereof, that is intentionally
|
||||
submitted to Licensor for inclusion in the Work by the copyright owner
|
||||
or by an individual or Legal Entity authorized to submit on behalf of
|
||||
the copyright owner. For the purposes of this definition, "submitted"
|
||||
means any form of electronic, verbal, or written communication sent
|
||||
to the Licensor or its representatives, including but not limited to
|
||||
communication on electronic mailing lists, source code control systems,

||||
|
||||

|
||||
subsequently incorporated within the Work.
|
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the
|
||||
Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
(except as stated in this section) patent license to make, have made,
|
||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||
APPENDIX: How to apply the Apache License to your work.
|
||||
|
||||
To apply the Apache License to your work, attach the following
|
||||
boilerplate notice, with the fields enclosed by brackets "{}"
|
||||
replaced with your own identifying information. (Don't include
|
||||
the brackets!) The text should be enclosed in the appropriate
|
||||
comment syntax for the file format. We also recommend that a
|
||||
file or class name and description of purpose be included on the
|
||||

# Go Wrapper for ZFS #
|
||||
|
||||
Simple wrappers for ZFS command line tools.
|
||||
|
||||
[](https://godoc.org/github.com/mistifyio/go-zfs)
|
||||
|
||||
## Requirements ##
|
||||
|
||||
You need a working ZFS setup. To use on Ubuntu 14.04, setup ZFS:
|
||||
|
||||
sudo apt-get install python-software-properties
|
||||
sudo apt-add-repository ppa:zfs-native/stable
|
||||
sudo apt-get update
|
||||
sudo apt-get install ubuntu-zfs libzfs-dev
|
||||
|
||||
Developed using Go 1.3, but currently there isn't anything 1.3 specific. Don't use Ubuntu packages for Go, use http://golang.org/doc/install
|
||||
|
||||
Generally you need root privileges to use anything zfs related.
|
||||
|
||||
## Status ##
|
||||
|
||||
This has been only been tested on Ubuntu 14.04
|
||||
|
||||
In the future, we hope to work directly with libzfs.
|
||||
|
||||
# Hacking #
|
||||
|
||||
The tests have decent examples for most functions.
|
||||
|
||||
```go
|
||||
//assuming a zpool named test
|
||||
//error handling omitted
|
||||
|
||||
|
||||
f, err := zfs.CreateFilesystem("test/snapshot-test", nil)
|
||||
ok(t, err)
|
||||
|
||||
s, err := f.Snapshot("test", nil)
|
||||
ok(t, err)
|
||||
|
||||
// snapshot is named "test/snapshot-test@test"
|
||||
|
||||
c, err := s.Clone("test/clone-test", nil)
|
||||
|
||||
err := c.Destroy()
|
||||
err := s.Destroy()
|
||||
err := f.Destroy()
|
||||
|
||||
```
