Contribute to GitLab

Thank you for your interest in contributing to GitLab. This guide details how to contribute to GitLab in a way that is efficient for everyone.

GitLab comes into two flavors, GitLab Community Edition (CE) our free and open source edition, and GitLab Enterprise Edition (EE) which is our commercial edition. Throughout this guide you will see references to CE and EE for abbreviation.

If you have read this guide and want to know how the GitLab [core-team][] operates please see the GitLab contributing process.

Contributor license agreement

By submitting code as an individual you agree to the individual contributor license agreement. By submitting code as an entity you agree to the corporate contributor license agreement.

Security vulnerability disclosure

Please report suspected security vulnerabilities in private to support@gitlab.com, also see the disclosure section on the GitLab.com website. Please do NOT create publicly viewable issues for suspected security vulnerabilities.

Closing policy for issues and merge requests

GitLab is a popular open source project and the capacity to deal with issues and merge requests is limited. Out of respect for our volunteers, issues and merge requests not in line with the guidelines listed in this document may be closed without notice.

Please treat our volunteers with courtesy and respect, it will go a long way towards getting your issue resolved.

Issues and merge requests should be in English and contain appropriate language for audiences of all ages.

Helping others

Please help other GitLab users when you can. The channels people will reach out on can be found on the getting help page.

Sign up for the mailing list, answer GitLab questions on StackOverflow or respond in the IRC channel. You can also sign up on CodeTriage to help with the remaining issues on the GitHub issue tracker.

I want to contribute!

If you want to contribute to GitLab, but are not sure where to start, look for issues with the label up-for-grabs. These issues will be of reasonable size and challenge, for anyone to start contributing to GitLab.

This was inspired by an article by Kent C. Dodds.

Issue tracker

To get support for your particular problem please use the getting help channels.

The GitLab CE issue tracker on GitLab.com is for bugs concerning the latest GitLab release and feature proposals.

When submitting an issue please conform to the issue submission guidelines listed below. Not all issues will be addressed and your issue is more likely to be addressed if you submit a merge request which partially or fully solves the issue.

If you're unsure where to post, post to the mailing list or Stack Overflow first. There are a lot of helpful GitLab users there who may be able to help you quickly. If your particular issue turns out to be a bug, it will find its way from there.

If it happens that you know the solution to an existing bug, please first open the issue in order to keep track of it and then open the relevant merge request that potentially fixes it.

Feature proposals

To create a feature proposal for CE and CI, open an issue on the issue tracker of CE.

For feature proposals for EE, open an issue on the issue tracker of EE.

In order to help track the feature proposals, we have created a feature proposal label. For the time being, users that are not members of the project cannot add labels. You can instead ask one of the core team members to add the label feature proposal to the issue.

Please keep feature proposals as small and simple as possible, complex ones might be edited to make them small and simple.

For changes in the interface, it can be helpful to create a mockup first. If you want to create something yourself, consider opening an issue first to discuss whether it is interesting to include this in GitLab.

Issue tracker guidelines

Search the issue tracker for similar entries before submitting your own, there's a good chance somebody else had the same issue or feature proposal. Show your support with an award emoji and/or join the discussion.

Please submit bugs using the following template in the issue description area. The text in the parenthesis is there to help you with what to include. Omit it when submitting the actual issue. You can copy-paste it and then edit as you see fit.

## Summary

(Summarize your issue in one sentence - what goes wrong, what did you expect to happen)

## Steps to reproduce

(How one can reproduce the issue - this is very important)

## Expected behavior

(What you should see instead)

## Relevant logs and/or screenshots

(Paste any relevant logs - please use code blocks (```) to format console output,
logs, and code as it's very hard to read otherwise.)

## Output of checks

### Results of GitLab Application Check

(For installations with omnibus-gitlab package run and paste the output of:
sudo gitlab-rake gitlab:check SANITIZE=true)

(For installations from source run and paste the output of:
sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production SANITIZE=true)

(we will only investigate if the tests are passing)

### Results of GitLab Environment Info

(For installations with omnibus-gitlab package run and paste the output of:
sudo gitlab-rake gitlab:env:info)

(For installations from source run and paste the output of:
sudo -u git -H bundle exec rake gitlab:env:info)

## Possible fixes

(If you can, link to the line of code that might be responsible for the problem)

Merge requests

We welcome merge requests with fixes and improvements to GitLab code, tests, and/or documentation. The features we would really like a merge request for are listed with the label Accepting Merge Requests on our issue tracker for CE and EE but other improvements are also welcome.

If you want to add a new feature that is not labeled it is best to first create a feedback issue (if there isn't one already) and leave a comment asking for it to be marked as Accepting merge requests. Please include screenshots or wireframes if the feature will also change the UI.

Merge requests can be filed either at GitLab.com or at github.com.

If you are new to GitLab development (or web development in general), see the I want to contribute! section to get you started with some potentially easy issues.

To start with GitLab development download the GitLab Development Kit and see the Development section for some guidelines.

Merge request guidelines

If you can, please submit a merge request with the fix or improvements including tests. If you don't know how to fix the issue but can write a test that exposes the issue we will accept that as well. In general bug fixes that include a regression test are merged quickly while new features without proper tests are least likely to receive timely feedback. The workflow to make a merge request is as follows:

  1. Fork the project into your personal space on GitLab.com
  2. Create a feature branch
  3. Write tests and code
  4. Add your changes to the CHANGELOG
  5. If you are changing the README, some documentation or other things which have no effect on the tests, add [ci skip] somewhere in the commit message
  6. If you have multiple commits please combine them into one commit by squashing them
  7. Push the commit(s) to your fork
  8. Submit a merge request (MR) to the master branch
  9. The MR title should describe the change you want to make
  10. The MR description should give a motive for your change and the method you used to achieve it
  11. If the MR changes the UI it should include before and after screenshots
  12. If the MR changes CSS classes please include the list of affected pages grep css-class ./app -R
  13. Link any relevant issues in the merge request description and leave a comment on them with a link back to the MR
  14. Be prepared to answer questions and incorporate feedback even if requests for this arrive weeks or months after your MR submission
  15. If your MR touches code that executes shell commands, reads or opens files or handles paths to files on disk, make sure it adheres to the shell command guidelines
  16. If your code creates new files on disk please read the shared files guidelines.

The official merge window is in the beginning of the month from the 1st to the 7th day of the month. This is the best time to submit an MR and get feedback fast. Before this time the GitLab Inc. team is still dealing with work that is created by the monthly release such as regressions requiring patch releases. After the 7th it is already getting closer to the release date of the next version. This means there is less time to fix the issues created by merging large new features.

Please keep the change in a single MR as small as possible. If you want to contribute a large feature think very hard what the minimum viable change is. Can you split the functionality? Can you only submit the backend/API code? Can you start with a very simple UI? Can you do part of the refactor? The increased reviewability of small MRs that leads to higher code quality is more important to us than having a minimal commit log. The smaller an MR is the more likely it is it will be merged (quickly). After that you can send more MRs to enhance it.

For examples of feedback on merge requests please look at already closed merge requests. If you would like quick feedback on your merge request feel free to mention one of the Merge Marshalls of the core team. Please ensure that your merge request meets the contribution acceptance criteria.

Definition of done

If you contribute to GitLab please know that changes involve more than just code. We have the following definition of done. Please ensure you support the feature you contribute through all of these steps.

  1. Description explaining the relevancy (see following item)
  2. Working and clean code that is commented where needed
  3. Unit and integration tests that pass on the CI server
  4. Documented in the /doc directory
  5. Changelog entry added
  6. Reviewed and any concerns are addressed
  7. Merged by the project lead
  8. Added to the release blog article
  9. Added to the website if relevant
  10. Community questions answered
  11. Answers to questions radiated (in docs/wiki/etc.)

If you add a dependency in GitLab (such as an operating system package) please consider updating the following and note the applicability of each in your merge request:

  1. Note the addition in the release blog post (create one if it doesn't exist yet) https://gitlab.com/gitlab-com/www-gitlab-com/merge_requests/
  2. Upgrade guide, for example https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/update/7.5-to-7.6.md
  3. Upgrader https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/update/upgrader.md#2-run-gitlab-upgrade-tool
  4. Installation guide https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/install/installation.md#1-packages-dependencies
  5. GitLab Development Kit https://gitlab.com/gitlab-org/gitlab-development-kit
  6. Test suite https://gitlab.com/gitlab-org/gitlab-ce/blob/master/scripts/prepare_build.sh
  7. Omnibus package creator https://gitlab.com/gitlab-org/omnibus-gitlab

Merge request description format

  1. What does this MR do?
  2. Are there points in the code the reviewer needs to double check?
  3. Why was this MR needed?
  4. What are the relevant issue numbers?
  5. Screenshots (if relevant)

Contribution acceptance criteria

  1. The change is as small as possible (see the above paragraph for details)
  2. Include proper tests and make all tests pass (unless it contains a test exposing a bug in existing code)
  3. If you suspect a failing CI build is unrelated to your contribution, you may try and restart the failing CI job or ask a developer to fix the aforementioned failing test
  4. Your MR initially contains a single commit (please use git rebase -i to squash commits)
  5. Your changes can merge without problems (if not please merge master, never rebase commits pushed to the remote server)
  6. Does not break any existing functionality
  7. Fixes one specific issue or implements one specific feature (do not combine things, send separate merge requests if needed)
  8. Migrations should do only one thing (eg: either create a table, move data to a new table or remove an old table) to aid retrying on failure
  9. Keeps the GitLab code base clean and well structured
  10. Contains functionality we think other users will benefit from too
  11. Doesn't add configuration options since they complicate future changes
  12. Changes after submitting the merge request should be in separate commits (no squashing). If necessary, you will be asked to squash when the review is over, before merging.
  13. It conforms to the following style guides:
    • If your change touches a line that does not follow the style, modify the entire line to follow it. This prevents linting tools from generating warnings.
    • Don't touch neighbouring lines. As an exception, automatic mass refactoring modifications may leave style non-compliant.

Style guides

  1. Ruby. Important sections include Source Code Layout and Naming. Use:
    • multi-line method chaining style Option B: dot . on previous line
    • string literal quoting style Option A: single quoted by default
  2. Rails
  3. Testing
  4. CoffeeScript
  5. Shell commands created by GitLab contributors to enhance security
  6. Markdown
  7. Database Migrations
  8. Documentation styleguide
  9. Interface text should be written subjectively instead of objectively. It should be the GitLab core team addressing a person. It should be written in present time and never use past tense (has been/was). For example instead of prohibited this user from being saved due to the following errors: the text should be sorry, we could not create your account because:

This is also the style used by linting tools such as RuboCop, PullReview and Hound CI.
