# Development Guide
|
|
|
|
## New to Go
|
|
|
|
Ceph-csi is written in Go and if you are new to the language,
|
|
it is **highly** encouraged to:
|
|
|
|
* Take the [A Tour of Go](http://tour.golang.org/welcome/1) course.
|
|
* [Set up](https://golang.org/doc/code.html) Go development environment on your machine.
|
|
* Read [Effective Go](https://golang.org/doc/effective_go.html) for best practices.
|
|
|
|
## Development Workflow
|
|
|
|
### Workspace and repository setup
|
|
|
|
* [Download](https://golang.org/dl/) Go (>=1.11.x) and
|
|
[install](https://golang.org/doc/install) it on your system.
|
|
* Setup the [GOPATH](http://www.g33knotes.org/2014/07/60-second-count-down-to-go.html)
|
|
environment.
|
|
* Run `$ go get -d github.com/ceph/ceph-csi`
|
|
This will just download the source and not build it. The downloaded source
|
|
will be at `$GOPATH/src/github.com/ceph/ceph-csi`
|
|
* Fork the [ceph-csi repo](https://github.com/ceph/ceph-csi) on Github.
|
|
* Add your fork as a git remote:
|
|
`$ git remote add fork https://github.com/<your-github-username>/ceph-csi`
|
|
|
|
> Editors: Our favorite editor is vim with the [vim-go](https://github.com/fatih/vim-go)
|
|
> plugin, but there are many others like [vscode](https://github.com/Microsoft/vscode-go)
|
|
|
|
### Building Ceph-CSI
|
|
|
|
To build ceph-csi run:
|
|
`$ make`
|
|
|
|
The built binary will be present under `_output/` directory.
|
|
|
|
### Code contribution workflow
|
|
|
|
ceph-csi repository currently follows GitHub's
|
|
[Fork & Pull] (<https://help.github.com/articles/about-pull-requests/>) workflow
|
|
for code contributions.
|
|
|
|
Please read the [coding guidelines](coding.md) document before submitting a PR.
|
|
|
|
Here is a short guide on how to work on a new patch. In this example, we will
|
|
work on a patch called *hellopatch*:
|
|
|
|
* `$ git checkout master`
|
|
* `$ git pull`
|
|
* `$ git checkout -b hellopatch`
|
|
|
|
Do your work here and commit.
|
|
|
|
Run the test suite, which includes linting checks, static code check, and unit
|
|
tests:
|
|
|
|
`$ make test`
|
|
|
|
You will need to provide unit tests and functional tests for your changes
|
|
wherever applicable.
|
|
|
|
Once you are ready to push, you will type the following:
|
|
|
|
`$ git push fork hellopatch`
|
|
|
|
**Creating A Pull Request:**
|
|
When you are satisfied with your changes, you will then need to go to your repo
|
|
in GitHub.com and create a pull request for your branch. Automated tests will
|
|
be run against the pull request. Your pull request will be reviewed and merged.
|
|
|
|
If you are planning on making a large set of changes or a major architectural
|
|
change it is often desirable to first build a consensus in an issue discussion
|
|
and/or create an initial design doc PR. Once the design has been agreed upon
|
|
one or more PRs implementing the plan can be made.
|
|
|
|
**Review Process:**
|
|
Once your PR has been submitted for review the following critieria will
|
|
need to be met before it will be merged:
|
|
|
|
* Each PR needs reviews accepting the change from at least two developers
|
|
* for merging
|
|
* It is common to request reviews from those reviewers automatically suggested
|
|
* by github
|
|
* Each PR needs to have been open for at least 24 working hours to allow for
|
|
* community feedback
|
|
* The 24 working hours counts hours occuring Mon-Fri in the local timezone
|
|
* of the submitter
|
|
* Each PR must be fully updated to master and tests must have passed
|
|
|
|
When the criteria are met, a project maintainer can merge your changes into
|
|
the project's master branch.
|
|
|
|
### Backport a Fix to a Release Branch
|
|
|
|
The flow for getting a fix into a release branch is:
|
|
|
|
1. Open a PR to merge the changes to master following the process outlined above.
|
|
1. Add the backport label to that PR such as `backport-to-release-vX.Y.Z`
|
|
1. After your PR is merged to master, the mergify bot will automatically open a
|
|
PR with your commits backported to the release branch
|
|
1. If there are any conflicts you will need to resolve them by pulling the
|
|
branch, resolving the conflicts and force push back the branch
|
|
1. After the CI is green, the bot will automatically merge the backport PR.
