# Make sure we don't have more than one active workflow to prevent race conditions
# e.g a previous toolchain build may tag and push `latest` later if we don't have
# this. It is ok to have parallel runs for push and PR events and from different
# branches. We can cancel previous runs for non-trunk events.

# negatives preventing an image build. In that case we might need to
# ask the committer for a fix. OTOH pull requests against the upstream
# repository will always compare against its default branch and cause a
# rebuild, making a valid test run.
