# How to Contribute
|
||
|
|
|
||
|
|
CSI is under [Apache 2.0](LICENSE) and accepts contributions via GitHub pull requests.
|
||
|
|
|
||
|
|
Contributions require signing an individual or Corporate CLA available [here](https://github.com/container-storage-interface/spec/blob/master/CCLA.pdf) which should be signed and mailed to the [mailing list]( https://groups.google.com/forum/#!topic/container-storage-interface-community/).
|
||
|
|
|
||
|
|
This document outlines some of the conventions on development workflow, commit message formatting, contact points and other resources to make it easier to get your contribution accepted.
|
||
|
|
|
||
|
|
## Markdown style
|
||
|
|
|
||
|
|
To keep consistency throughout the Markdown files in the CSI spec, all files should be formatted one sentence per line.
|
||
|
|
This fixes two things: it makes diffing easier with git and it resolves fights about line wrapping length.
|
||
|
|
For example, this paragraph will span three lines in the Markdown source.
|
||
|
|
|
||
|
|
## Code style
|
||
|
|
|
||
|
|
This also applies to the code snippets in the markdown files.
|
||
|
|
|
||
|
|
* Please wrap the code at 72 characters.
|
||
|
|
|
||
|
|
## Comments
|
||
|
|
|
||
|
|
This also applies to the code snippets in the markdown files.
|
||
|
|
|
||
|
|
* End each sentence within a comment with a punctuation mark (please note that we generally prefer periods); this applies to incomplete sentences as well.
|
||
|
|
* For trailing comments, leave one space between the end of the code and the beginning of the comment.
|
||
|
|
|
||
|
|
## Git commit
|
||
|
|
|
||
|
|
The "system of record" for the specification is the `spec.md` file and all hand-edits of the specification should happen there.
|
||
|
|
**DO NOT** manually edit the generated protobufs or generated language bindings.
|
||
|
|
Once changes to `spec.md` are complete, please run `make` to update generated files.
|
||
|
|
|
||
|
|
**IMPORTANT:** Prior to committing code please run `make` to ensure that your specification changes have landed in all generated files.
|
||
|
|
|
||
|
|
### Commit Style
|
||
|
|
|
||
|
|
Each commit should represent a single logical (atomic) change: this makes your changes easier to review.
|
||
|
|
|
||
|
|
* Try to avoid unrelated cleanups (e.g., typo fixes or style nits) in the same commit that makes functional changes.
|
||
|
|
While typo fixes are great, including them in the same commit as functional changes makes the commit history harder to read.
|
||
|
|
* Developers often make incremental commits to save their progress when working on a change, and then “rewrite history” (e.g., using `git rebase -i`) to create a clean set of commits once the change is ready to be reviewed.
|
||
|
|
|
||
|
|
Simple house-keeping for clean git history.

|
||
|
|
|
||
|
|
* Separate the subject from body with a blank line.
|
||
|
|
* Limit the subject line to 50 characters.
|
||
|
|
* Capitalize the subject line.
|
||
|
|
* Do not end the subject line with a period.
|
||
|
|
* Use the imperative mood in the subject line.
|
||
|
|
* Wrap the body at 72 characters.
|
||
|
|
* Use the body to explain what and why vs. how.
|
||
|
|
* If there was important/useful/essential conversation or information, copy or include a reference.
|
||
|
|
* When possible, one keyword to scope the change in the subject (i.e. "README: ...", "tool: ...").
