Repository

DETAILS: Tier: Free, Premium, Ultimate Offering: GitLab.com, Self-managed, GitLab Dedicated

A repository is where you store your code, make changes, and track changes using version control. Each project contains a repository and a repository cannot exist without a project.

Create a repository

To create a repository:

Add files to a repository

You can add files to a repository:

Add a file from the UI

To add or upload a file from the GitLab UI:

  1. On the left sidebar, select Search or go to and find your project.
  2. Go to the directory you want to upload the file to.
  3. Next to the directory name, select the plus icon ({plus}) > Upload file.
  4. Drop or upload your file.
  5. Enter a commit message.
  6. Optional. To create a merge request with your changes, in Target branch, enter a branch name that's not your repository's default branch.
  7. Select Upload file.

Commit changes to a repository

You can commit your changes to a branch in the repository. When you use the command line, use git commit.

For information about how to use commits to improve communication and collaboration, trigger or skip pipelines, and reverting changes, see commits.

Clone a repository

You can clone a repository using the:

Download repository source code

When you download a repository's source code, it is compressed and saved as an archive file. To download the source code stored in a repository:

  1. On the left sidebar, select Search or go to and find your project.

  2. Above the file list, select Code.

  3. From the options, select the files you want to download:

    • Source code:

      Download the source code from the current branch you're viewing. Available extensions: zip, tar, tar.gz, and tar.bz2.

    • Directory:

      Download a specific directory. Visible only when you view a subdirectory. Available extensions: zip, tar, tar.gz, and tar.bz2.

    • Artifacts:

      Download the artifacts from the latest CI/CD job.

The checksums of generated archives can change even if the repository itself doesn't change. For example, this occurs if Git or a third-party library that GitLab uses changes.

Repository languages

GitLab detects programming languages used in the default branch. This information is displayed on the Project overview page.

Repository Languages bar

When new files are added, this information can take up to five minutes to update.

Add repository languages

Not all files are detected and listed on the Project overview page. Documentation, vendor code, and most markup languages are excluded. To view a list of supported files and languages, see supported data types.

To change this behavior and include additional file types in the default settings:

  1. In your repository's root directory, create a file named .gitattributes.

  2. Add a line that tells GitLab to include a specific file type. For example, to enable .proto files, add the following:

    *.proto linguist-detectable=true

This feature can use excessive CPU. If you experience an issue, see the Repository Languages: excessive CPU use troubleshooting section.

Repository contributor analytics

You can view a line chart with the number of commits to the selected project branch over time, and line charts with the number of commits by each project member. For more information, see Contributor analytics.

Repository history graph

A repository graph displays a visual history of the repository network, including branches and merges. This graph can help you visualize the Git flow strategy used in the repository.

To view the repository history graph, go to your project's Code > Repository graph.

Repository path changes

When a repository path changes, GitLab handles the transition from the old location to the new one with a redirect.

When you rename a user, change a group path, or rename a repository:

  • URLs for the namespace and everything under it, like projects, are redirected to the new URLs.
  • Git remote URLs for projects under the namespace redirect to the new remote URL. When you push or pull to a repository that has changed location, a warning message to update your remote is displayed. Automation scripts or Git clients continue to work after a rename.
  • The redirects are available as long as the original path is not claimed by another group, user, or project.
  • API redirects may need to be followed explicitly.

After you change a path, you must update the existing URL in the following resources:

Troubleshooting

Search sequence of pushes to a repository

If it seems that a commit has gone "missing", search the sequence of pushes to a repository. This StackOverflow article describes how you can end up in this state without a force push. Another cause can be a misconfigured server hook that changes a HEAD ref in a git reset operation.

If you look at the output from the sample code below for the target branch, you see a discontinuity in the from/to commits as you step through the output. The commit_from of each new push should equal the commit_to of the previous push. A break in that sequence indicates one or more commits have been "lost" from the repository history.

Using the rails console, the following example checks the last 100 pushes and prints the commit_from and commit_to entries:

p = Project.find_by_full_path('project/path')
p.events.pushed_action.last(100).each do |e|
  printf "%-20.20s %8s...%8s (%s)", e.push_event_payload[:ref], e.push_event_payload[:commit_from], e.push_event_payload[:commit_to], e.author.try(:username)
end ; nil

Example output showing break in sequence at line 4:

Error: Xcode fails to clone repository

GitLab provides an option to restrict a list of allowed SSH keys. If your SSH key is not on the allowed list, you might encounter an error like The repository rejected the provided credentials.

To resolve this issue, create a new SSH key pair that meets the guidelines for supported SSH key types. After you generate a supported SSH key, try cloning the repository again.
