# Run this script in the Jenkins "Execute shell" build action to upload test
# artifacts to GCS. Since it uses gsutil directly, it's a bit faster at
# uploading large numbers of files than the GCS Jenkins plugin.
# We also intentionally ignore gsutil errors since we don't want failed uploads
# to fail the entire test run (#13548).

# Note: for magicfile support to work correctly, the "file" utility must be
# installed.

# TODO: eventually fold this all into upload-finished.sh, once every job is
# using it.
