Gerrit Code Review - Contributor Agreements

Users can be required to sign one or more contributor agreements before being able to submit a change in a project.

Contributor agreements are global and can be configured by modifying the project.config file on the All-Projects project. Push permission needs to be granted for the refs/meta/config branch to be able to push back the project.config file. Consult access controls for details on how access permissions work.

To retrieve the project.config file, initialize a temporary Git repository to edit the configuration:

  mkdir cfg_dir
  cd cfg_dir
  git init

Download the existing configuration from Gerrit:

  git fetch ssh://localhost:29418/All-Projects refs/meta/config
  git checkout FETCH_HEAD

Contributor agreements are defined as contributor-agreement sections in project.config:

  [contributor-agreement "Individual"]
    description = If you are going to be contributing code on your own, this is the one you want. You can sign this one online.
    agreementUrl = static/cla_individual.html
    autoVerify = group CLA Accepted - Individual
    accepted = group CLA Accepted - Individual

Each contributor-agreement section within the project.config file must have a unique name. The section name will appear in the web UI.

If not already present, add the group(s) used in the autoVerify and accepted variables in the groups file:

    # UUID                                      Group Name
    #
    3dedb32915ecdbef5fced9f0a2587d164cd614d4    CLA Accepted - Individual

Commit the configuration change, and push it back:

  git commit -a -m "Add Individual contributor agreement"
  git push ssh://localhost:29418/All-Projects HEAD:refs/meta/config

• contributor-agreement.<name>.description
  Short text describing the contributor agreement. This text will appear when the user selects an agreement.

• contributor-agreement.<name>.agreementUrl
  An absolute URL or a relative path to an HTML file containing the text of the contributor agreement. The URL must use the http or https scheme. The path is relative to the gerrit.basePath variable in gerrit.config.

• contributor-agreement.<name>.autoVerify
  If present, the user can sign the contributor agreement online. The value is the group to which the user will be added after signing the agreement. The group’s UUID must also appear in the groups file.

• contributor-agreement.<name>.accepted
  List of groups that will be considered when verifying that a contributor agreement has been accepted. The groups’ UUID must also appear in the groups file.
