# 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 easy for everyone.
|
|
|
|
For a first-time step-by-step guide to the contribution process, see our
|
|
[Contributing to GitLab](https://about.gitlab.com/community/contribute/) page.
|
|
|
|
Looking for something to work on? See the
|
|
[How to contribute](#how-to-contribute) section for more information.
|
|
|
|
GitLab comes in two flavors:
|
|
|
|
- GitLab Community Edition (CE), our free and open source edition.
|
|
- GitLab Enterprise Edition (EE), which is our commercial edition.
|
|
|
|
Throughout this guide you will see references to CE and EE for abbreviation.
|
|
|
|
To get an overview of GitLab community membership, including those that would review or merge
|
|
your contributions, visit [the community roles page](community_roles.md).
|
|
|
|
If you want to know how the GitLab [core team](https://about.gitlab.com/community/core-team/)
|
|
operates, see [the GitLab contributing process](https://gitlab.com/gitlab-org/gitlab/-/blob/master/PROCESS.md).
|
|
|
|
GitLab Inc engineers should refer to the [engineering workflow document](https://about.gitlab.com/handbook/engineering/workflow/).
|
|
|
|
## Security vulnerability disclosure
|
|
|
|
Report suspected security vulnerabilities in private to
|
|
`support@gitlab.com`, also see the
|
|
[disclosure section on the GitLab.com website](https://about.gitlab.com/security/disclosure/).
|
|
|
|
WARNING:
|
|
Do **NOT** create publicly viewable issues for suspected security vulnerabilities.
|
|
|
|
## Code of conduct
|
|
|
|
We want to create a welcoming environment for everyone who is interested in contributing.
|
|
Visit our [Code of Conduct page](https://about.gitlab.com/community/contribute/code-of-conduct/) to learn more about our commitment to an open and welcoming environment.
|
|
|
|
## 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.
|
|
|
|
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.
|
|
|
|
If a contributor is no longer actively working on a submitted merge request,
|
|
we can:
|
|
|
|
- Decide that the merge request will be finished by one of our
|
|
[Merge request coaches](https://about.gitlab.com/company/team/).
|
|
- Close the merge request.
|
|
|
|
We make this decision based on how important the change is for our product vision. If a merge
|
|
request coach is going to finish the merge request, we assign the
|
|
`~coach will finish` label.
|
|
|
|
When a team member picks up a community contribution,
|
|
we credit the original author by adding a changelog entry crediting the author
|
|
and optionally include the original author on at least one of the commits
|
|
within the MR.
|
|
|
|
## Closing policy for inactive bugs
|
|
|
|
GitLab values the time spent by contributors on reporting bugs. However, if a bug remains inactive for a very long period,
|
|
it will qualify for auto-closure. Please refer to the [auto-close inactive bugs](https://about.gitlab.com/handbook/engineering/quality/triage-operations/#auto-close-inactive-bugs) section in our handbook to understand the complete workflow.
|
|
|
|
## Helping others
|
|
|
|
Help other GitLab users when you can.
|
|
The methods people use to seek help can be found on the [getting help page](https://about.gitlab.com/get-help/).
|
|
|
|
Sign up for the mailing list, answer GitLab questions on StackOverflow or respond in the IRC channel.
|
|
|
|
## How to contribute
|
|
|
|
If you would like to contribute to GitLab:
|
|
|
|
- Issues with the
|
|
[`~Accepting merge requests` label](issue_workflow.md#label-for-community-contributors)
|
|
are a great place to start.
|
|
- Optimizing our tests is another great opportunity to contribute. You can use
|
|
[RSpec profiling statistics](https://gitlab-org.gitlab.io/rspec_profiling_stats/) to identify
|
|
slowest tests. These tests are good candidates for improving and checking if any of
|
|
[best practices](../testing_guide/best_practices.md)
|
|
could speed them up.
|
|
- Consult the [Contribution Flow](#contribution-flow) section to learn the process.
|
|
|
|
If you have any questions or need help visit [Getting Help](https://about.gitlab.com/get-help/) to
|
|
learn how to communicate with GitLab. We have a [Gitter channel for contributors](https://gitter.im/gitlab/contributors),
|
|
however we favor
|
|
[asynchronous communication](https://about.gitlab.com/handbook/communication/#internal-communication) over real time communication.
|
|
|
|
Thanks for your contribution!
|
|
|
|
### GitLab Development Kit
|
|
|
|
The GitLab Development Kit (GDK) helps contributors run a local GitLab instance with all the
|
|
required dependencies. It can be used to test changes to GitLab and related projects before raising
|
|
a Merge Request.
|
|
|
|
For more information, see the [`gitlab-development-kit`](https://gitlab.com/gitlab-org/gitlab-development-kit)
|
|
project.
|
|
|
|
### Contribution flow
|
|
|
|
The general flow of contributing to GitLab is:
|
|
|
|
1. [Create a fork](../../user/project/repository/forking_workflow.md#creating-a-fork)
|
|
of GitLab. In some cases, you will want to set up the
|
|
[GitLab Development Kit](https://gitlab.com/gitlab-org/gitlab-development-kit) to
|
|
[develop against your fork](https://gitlab.com/gitlab-org/gitlab-development-kit/-/blob/main/doc/index.md#develop-in-your-own-gitlab-fork).
|
|
1. Make your changes in your fork.
|
|
1. When you're ready, [create a new merge request](../../user/project/merge_requests/creating_merge_requests.md).
|
|
1. In the merge request's description:
|
|
- Ensure you provide complete and accurate information.
|
|
- Review the provided checklist.
|
|
1. Assign the merge request (if possible) to, or [mention](../../user/project/issues/issue_data_and_actions.md#mentions),
|
|
one of the [code owners](../../user/project/code_owners.md) for the relevant project,
|
|
and explain that you are ready for review.
|
|
|
|
When you submit code to GitLab, we really want it to get merged! However, we always review
|
|
submissions carefully, and this takes time. Code submissions will usually be reviewed by two
|
|
[domain experts](../code_review.md#domain-experts) before being merged:
|
|
|
|
- A [reviewer](../code_review.md#the-responsibility-of-the-reviewer).
|
|
- A [maintainer](../code_review.md#the-responsibility-of-the-maintainer).
|
|
|
|
Keep the following in mind when submitting merge requests:
|
|
|
|
- When reviewers are reading through a merge request they may request guidance from other
|
|
reviewers.
|
|
- If the code quality is found to not meet GitLab standards, the merge request reviewer will
|
|
provide guidance and refer the author to our:
|
|
- [Documentation](../documentation/styleguide/index.md) style guide.
|
|
- [Code style guides](style_guides.md).
|
|
- Sometimes style guides will be followed but the code will lack structural integrity, or the
|
|
reviewer will have reservations about the code's overall quality. When there is a reservation,
|
|
the reviewer will inform the author and provide some guidance.
|
|
- Though GitLab generally allows anyone to indicate
|
|
[approval](../../user/project/merge_requests/approvals/index.md) of merge requests, the
|
|
maintainer may require [approvals from certain reviewers](../code_review.md#approval-guidelines)
|
|
before merging a merge request.
|
|
- After review, the author may be asked to update the merge request. Once the merge request has been
|
|
updated and reassigned to the reviewer, they will review the code again. This process may repeat
|
|
any number of times before merge, to help make the contribution the best it can be.
|
|
|
|
Sometimes a maintainer may choose to close a merge request. They will fully disclose why it will not
|
|
be merged, as well as some guidance. The maintainers will be open to discussion about how to change
|
|
the code so it can be approved and merged in the future.
|
|
|
|
GitLab will do its best to review community contributions as quickly as possible. Specially
|
|
appointed developers review community contributions daily. Look at the
|
|
[team page](https://about.gitlab.com/company/team/) for the merge request coach who specializes in
|
|
the type of code you have written and mention them in the merge request. For example, if you have
|
|
written some front-end code, you should mention the frontend merge request coach. If
|
|
your code has multiple disciplines, you may mention multiple merge request coaches.
|
|
|
|
GitLab receives a lot of community contributions. If your code has not been reviewed within two
|
|
working days of its initial submission, feel free to mention all merge request coaches with
|
|
`@gitlab-org/coaches` to get their attention.
|
|
|
|
When submitting code to GitLab, you may feel that your contribution requires the aid of an external
|
|
library. If your code includes an external library, please provide a link to the library, as well as
|
|
reasons for including it.
|
|
|
|
Mention a maintainer in merge requests that contain:
|
|
|
|
- More than 500 changes.
|
|
- Any major [breaking changes](#breaking-changes).
|
|
- External libraries.
|
|
|
|
If you are not sure who to mention, the reviewer will do this for you early in the merge request process.
|
|
|
|
#### Breaking changes
|
|
|
|
A "breaking change" is any change that requires users to make a corresponding change to their code, settings, or workflow. "Users" might be humans, API clients, or even code classes that "use" another class. Examples of breaking changes include:
|
|
|
|
- Removing a user-facing feature without a replacement/workaround.
|
|
- Changing the definition of an existing API (by doing things like re-naming query parameters or changing routes).
|
|
- Removing a public method from a code class.
|
|
|
|
A breaking change can be considered "major" if it affects many users, or represents a significant change in behavior.
|
|
|
