These are important.
People contributing code to this project must adhere to the following rules. These standards are in place to keep code clean, consistent, and stable.
There are two types of documentation: source and markdown.
All source code should be documented in accordance with the Go's documentation rules.
When creating or modifying the project's
README.md file or any of the
documentation in the
.docs directory, please keep the following rules in
- All links to internal resources should be relative.
- All links to markdown files should include the file extension.
For example, the below link points to the anchor
basic-configuration on the
However, when the above link is followed when viewing this page directly from the Github repository instead of the generated site documentation, the link will return a 404.
While it's recommended that users view the generated site documentation instead of the source Markdown directly, we can still fix it so that the above link will work regardless. To fix the link, simply make it relative and add the Markdown file extension:
Now the link will work regardless from where it's viewed.
Style & Syntax
All source files should be processed by the following tools prior to being committed. Any errors or warnings produced by the tools should be corrected before the source is committed.
|gofmt||A golang source formatting tool|
|golint||A golang linter|
|govet||A golang source optimization tool|
|gocyclo||A golang cyclomatic complexity detection tool. No function should have a score above 0.15|
In lieu of using Atom as the IDE, the project's build procedures as outlined in build-references.md automatically executes the above tools as part of the build process and will fail the build if problems are discovered.
All new work submitted to the project should have associated tests where applicable. If there is ever a question of whether or not a test is applicable then the answer is likely yes.
This project uses
for code coverage, and all pull requests are processed just as a build from
If a pull request decreases the project's code coverage, the pull request will be
declined until such time that testing is added or enhanced to compensate.
Commit messages should follow the guide 5 Useful Tips For a Better Commit Message. The two primary rules to which to adhere are:
Commit message subjects should not exceed 50 characters in total and should be followed by a blank line.
The commit message's body should not have a width that exceeds 72 characters.
For example, the following commit has a very useful message that is succinct without losing utility.
commit e80c696939a03f26cd180934ba642a729b0d2941 Date: Tue Oct 20 23:47:36 2015 -0500 Added --format,-f option for CLI This patch adds the flag '--format' or '-f' for the following CLI commands: * adapter instances * device [get] * snapshot [get] * snapshot copy * snapshot create * volume [get] * volume attach * volume create * volume map * volume mount * volume path The user can specify either '--format=yml|yaml|json' or '-f yml|yaml|json' in order to influence how the resulting, structured data is marshaled prior to being emitted to the console.
Please note that the output above is the full output for viewing a commit. However, because the above message adheres to the commit message rules, it's quite easy to show just the commit's subject:
$ git show e80c696939a03f26cd180934ba642a729b0d2941 --format="%s" -s Added --format,-f option for CLI
It's also equally simple to print the commit's subject and body together:
$ git show e80c696939a03f26cd180934ba642a729b0d2941 --format="%s%n%n%b" -s Added --format,-f option for CLI This patch adds the flag '--format' or '-f' for the following CLI commands: * adapter instances * device [get] * snapshot [get] * snapshot copy * snapshot create * volume [get] * volume attach * volume create * volume map * volume mount * volume path The user can specify either '--format=yml|yaml|json' or '-f yml|yaml|json' in order to influence how the resulting, structured data is marshaled prior to being emitted to the console.
All developers are required to follow the GitHub Flow model when proposing new features or even submitting fixes.
Please note that although not explicitly stated in the referenced GitHub Flow model, all work should occur on a fork of this project, not from within a branch of this project itself.
Pull requests submitted to this project should adhere to the following guidelines:
Branches should be rebased off of the upstream master prior to being opened as pull requests and again prior to merge. This is to ensure that the build system accounts for any changes that may only be detected during the build and test phase.
Unless granted an exception a pull request should contain only a single commit. This is because features and patches should be atomic -- wholly shippable items that are either included in a release, or not. Please squash commits on a branch before opening a pull request. It is not a deal-breaker otherwise, but please be prepared to add a comment or explanation as to why you feel multiple commits are required.
