#
#  Direct push access to the main freeradius-server repo has been disabled in an attempt
#  to keep CI passing reliably.
#
#  The code below will automatically push to the main repository if a commit passes CI in
#  your fork on a branch that exists in the main repository.
#
#  The code below will only run if PERSONAL_ACCESS_TOKEN is defined in the repository
#  secrets for your fork of the freeradius-server repo.
#
#  If the above CI checks pass then we auto-merge into the same branch in the
#  main FR repo (only on push) if the PERSONAL_ACCESS_TOKEN secret is defined, i.e. when
#  the actor claims to be a FreeRADIUS developer with push access.
#
#  Personal access tokens can be generated via the GitHub website:
#
#  - Click on the Profile menu (top right)
#    > Settings
#    > Developer settings
#    > Personal access tokens
#    > Generate New Token
#  - Next, add the following settings and scopes:
#    Note: FreeRADIUS CI Push
#    public_repo (checked)
#
#  This will allow any git operations using this PERSONAL_ACCESS_TOKEN to commit code to any
#  public repository you have access to.
#
#  As this PERSONAL_ACCESS_TOKEN will only ever be accessible from GitHub actions when they are
#  running from your fork of the FreeRADIUS repo, this shouldn't be a security issue.
#
#  After generating your PERSONAL_ACCESS_TOKEN you will need to add it as a secret to your
#  repository.
#
#  - Copy your new token
#  - Click on the Profile menu (top right)
#    > Your repositories
#  - Search for freeradius-server
#    > Click freeradius-server
#  - Click settings in the tabs on the left
#  - Click secrets in the menu items on the left
#  - Click New repository secret
#  - Name: PERSONAL_ACCESS_TOKEN
#    Value: <value you copied>
#  - Click Add secret
  #
  #  Needed because secrets are not available for evaluation in if conditions
  #  at the job level, so we evaluate the existence of the PERSONAL_ACCESS_TOKEN secret
  #  within a step and export the result instead. We also extract the short
  #  branch name here because it's convenient to do so.
