# We need to use a personal access token here, instead of secrets.GITHUB_TOKEN. It will
# be persisted for the next step, where using a personal access token is necessary
# so that pushing to master will trigger the build.yml workflow. See
# https://github.community/t/push-from-action-does-not-trigger-subsequent-action/16854
#
# To create a personal access token, log in to github and add a token at
# https://github.com/settings/tokens. It it necessary and sufficient that the token have
# the "public_repo" scope. The relevant user also needs permission to push to master of
# this repo.

# Not doing: Ideally, if we generated a new commit in the previous step, we would upload new
# oleans here to save us having to rebuild in the build.yml action. This seems too hard to be
# worth doing (absent a broader refactor) for the following reasons:
# * the timing's off: the build.yml workflow fires on push, which happens in the previous
# step, so that the build.yml workflow might go looking for oleans before we've uploaded
# them.
# * we need to build again first, because the build is not idempotent; alternatively, upload
# what we have here but then have build.yml overwrite when it rebuilds;
# * (easy to solve) we have to figure out if the previous step made a commit.
