# We use pull_request_target such that Nixpkgs diff processing also works, | |
# because we need repository secrets for that, which pull_request doesn't allow from forks. | |
# However, it's very important that we don't run code from forks without sandboxing it, | |
# because that way anybody could potentially extract repository secrets! | |

# To prevent running untrusted code from forks, | |
# pull_request_target will cause the base branch to be checked out, not the PR branch. | |
# This is exactly what we want in this case, | |
# because the sync-pr.sh script cannot be run sandboxed since it needs to have side effects. | |
# Instead, the script itself fetches the PR, but then runs its code within sandboxed derivations. | |
