Tutorial: Adding LSIF to many repositories

Prerequisites

  • You have a private Sourcegraph instance (i.e., you're not using Sourcegraph.com), and the repositories you wish to explore have been added to that instance.
  • You have admin access on your Sourcegraph instance.
  • You have installed src-cli to your local machine.
  • You have the ability to create org-level secrets in your GitHub organization.
  • Your Sourcegraph instance is accessible from your GitHub instance. If you are using GitHub.com, this means your Sourcegraph instance is accessible on the public Internet.

Directions

Watch the video or follow the written directions below:

  1. Generate an access token for your Sourcegraph instance. The access token does NOT need sudo privileges, but should have permission to read every repository for which LSIF should be enabled.

  2. Create the following secrets in each GitHub organization represented in the set of repositories. Follow the GitHub documentation for doing this.

    1. srcEndpoint: the URL of the Sourcegraph instance, from the perspective of the GitHub instance. If using GitHub.com, this is just the URL you use to access Sourcegraph.
    2. srcAccessToken: the Sourcegraph access token you just created.

  3. Download lsif-go.campaign.yaml to your local machine.

  4. Verify the list of repositories for which you wish to enable LSIF:

    # Use the values you set in your GitHub secrets for SRC_ENDPOINT and SRC_ACCESS_TOKEN
SRC_ENDPOINT= SRC_ACCESS_TOKEN= src campaigns repos -f lsif-go.campaign.yaml

    If the set of repositories displayed is not the set of repositories for which you want to enable LSIF, modify the repositoriesMatchingQuery line in lsif-go.campaign.yaml to specify the Sourcegraph search query that selects the desired repository set.

  5. Run the campaign to generate a list of all pull requests that will be created:

    # Use the values you set in your GitHub secrets for SRC_ENDPOINT and SRC_ACCESS_TOKEN.
SRC_ENDPOINT= SRC_ACCESS_TOKEN= src campaigns preview -f lsif-go.campaign.yaml

    This will create a campaign preview in Sourcegraph. Navigate to the URL printed in the terminal to preview all the pull requests that will be created.

  6. Once you've verified the preview looks correct, change published: false to published: true in lsif-go.campaign.yaml and run the following:

 # Use the values you set in your GitHub secrets for SRC_ENDPOINT and SRC_ACCESS_TOKEN.
SRC_ENDPOINT= SRC_ACCESS_TOKEN= src campaigns apply -f lsif-go.campaign.yaml

Now, go back to the campaign page and verify the pull requests have been created.

  1. If there are errors creating any pull request, check to make sure the GitHub token in the Sourcegraph code host configuration (Site admin > Manage repositories) has the necessary scopes (repo and (read:discussion or read:org)).

  2. Verify that the GitHub action has run successfully in the repositories on GitHub.

  3. Verify that the LSIF data has been successfully uploaded to Sourcegraph by navigating to any repository page on Sourcegraph > Settings > Code intelligence: Uploads. You should also be able to explore the code at that revision with precise code navigation.

  4. Merge the pull requests created by the campaign and close the campaign. The GitHub action should now run on each push, generating LSIF data for the pushed revision and uploading this data to your Sourcegraph instance.
