Contributing to Incident I3A Repository

We would love for you to contribute and help make it even better than it is today! As a contributor, here are the guidelines we would like you to follow:

Submission Guidelines

Submitting an Issue

Before you submit an issue, please search the issue tracker, maybe an issue for your problem already exists and the discussion might inform you of workarounds readily available.

Note

Please try to put as much information as possible about the issue as possible. Some tips are a discriptive title and ussing the issue template.

Submitting a Pull Request (PR)

Before you submit your Pull Request (PR) consider the following guidelines:

  1. Search GitHub for an open or closed PR that relates to your submission. You don't want to duplicate effort.

  2. Fork the Arquisoft/Inci_i3a repo.

  3. Make your changes in a new git branch:

    git checkout -b my-fix-branch master

  4. Create your patch, including appropriate test cases.

  5. Follow our Coding Rules.

  6. Run the full Inci test suite, as described in the [developer documentation][dev-doc], and ensure that all tests pass.

  7. Commit your changes using a descriptive commit message that follows our commit message conventions. Adherence to these conventions is necessary because release notes are automatically generated from these messages.

    git commit -a

    Note: the optional commit -a command line option will automatically "add" and "rm" edited files.

  8. Push your branch to GitHub:

    git push origin my-fix-branch

  9. In GitHub, send a pull request to Inci_i3a:master.

  • If we suggest changes then:

    • Make the required updates.

    • Re-run the Inci test suites to ensure tests are still passing.

    • Rebase your branch and force push to your GitHub repository (this will update your Pull Request):

      git rebase master -i
git push -f

That's it! Thank you for your contribution!

After your pull request is merged

After your pull request is merged, you can safely delete your branch and pull the changes from the main (upstream) repository:

  • Delete the remote branch on GitHub either through the GitHub web UI or your local shell as follows:

    git push origin --delete my-fix-branch

  • Check out the master branch:

    git checkout master -f

  • Delete the local branch:

    git branch -D my-fix-branch

  • Update your master with the latest upstream version:

    git pull --ff upstream master

Coding Rules

To ensure consistency throughout the source code, keep these rules in mind as you are working:

  • All features or bug fixes must be tested by one or more specs (unit-tests).
  • All features or bug fixes that affects a service must be tested by the integration-tests.
  • All public API methods must be documented. (Details TBC).
  • We follow the Java Code Conventions.

Commit Message Guidelines

We have very precise rules over how our git commit messages can be formatted. This leads to more readable messages that are easy to follow when looking through the project history. But also, we use the git commit messages to generate the change log.

Commit Message Format

Each commit message consists of a header, a body and a footer. The header has a special format that includes a type, a scope and a subject:

<type>(<scope>): <subject>
<BLANK LINE>
<body>
<BLANK LINE>
<footer>

The header is mandatory and the scope of the header is optional.

Any line of the commit message cannot be longer 100 characters! This allows the message to be easier to read on GitHub as well as in various git tools.

The footer should contain a closing reference to an issue if any.

Samples: (even more samples)

docs(changelog): update changelog to beta.5

fix(release): need to depend on latest rxjs and zone.js

The version in our package.json gets copied to the one we publish, and users need the latest of these.

Revert

If the commit reverts a previous commit, it should begin with revert: , followed by the header of the reverted commit. In the body it should say: This reverts commit <hash>., where the hash is the SHA of the commit being reverted.

Type

Must be one of the following:

  • ci: Changes to our CI configuration files and scripts (example scopes: Travis, Circle, BrowserStack, SauceLabs)
  • docs: Documentation only changes
  • feat: A new feature
  • fix: A bug fix
  • perf: A code change that improves performance
  • refactor: A code change that neither fixes a bug nor adds a feature
  • style: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
  • test: Adding missing tests or correcting existing tests

Scope

The scope should be the name of the package affected (as perceived by the person reading the changelog generated from commit messages.

The following is the list of supported scopes:

  • NOT IMPLEMENTED YET

There are currently a few exceptions to the "use package name" rule:

  • changelog: used for updating the release notes in CHANGELOG.md
  • none/empty string: useful for style, test and refactor changes that are done across all packages (e.g. style: add missing semicolons)

Subject

The subject contains a succinct description of the change:

  • use the imperative, present tense: "change" not "changed" nor "changes"
  • don't capitalize the first letter
  • no dot (.) at the end

Body

Just as in the subject, use the imperative, present tense: "change" not "changed" nor "changes". The body should include the motivation for the change and contrast this with previous behavior.

Footer

The footer should contain any information about Breaking Changes and is also the place to reference GitHub issues that this commit Closes.

Breaking Changes should start with the word BREAKING CHANGE: with a space or two newlines. The rest of the commit message is then used for this.
