#!/usr/bin/env bash

# This file is the entrypoint for the rolling upgrade test.
# Description of test:
# Stage 1:
#  * Set up a storj-sim network on the latest point release (all storagenodes and satellite on latest point release).
#  * If the current commit is a release tag use the previous release instead. Exclude -rc release tags.
#  * Check out the latest point release of the uplink.
#  * (test-versions.sh upload) - Upload an inline, remote, and multisegment file to the network with the selected uplink.
# Stage 2:
#  * Upgrade the satellite to current commit. Run an "old" satellite api server on the latest point release (port 30000).
#  * Keep half of the storagenodes on the latest point release. Upgrade the other half to main.
#  * Point half of the storagenodes to the old satellite api (port 30000). Keep the other half on the new satellite api (port 10000).
#  * Check out the main version of the uplink.
#  * (test-rolling-upgrade.sh) - Download the inline, remote, and multisegment file from the network using the main uplink and the new satellite api.
#  * (test-rolling-upgrade.sh) - Download the inline, remote, and multisegment file from the network using the main uplink and the old satellite api.
#  * (test-rolling-upgrade-final-upload.sh) - Upload an inline, remote, and multisegment file to the network using the main uplink and the new satellite api.
#  * (test-rolling-upgrade-final-upload.sh) - Upload an inline, remote, and multisegment file to the network using the main uplink and the old satellite api.
#  * (test-rolling-upgrade-final-upload.sh) - Download the six inline, remote, and multisegment files from the previous two steps using the main uplink and new satellite api.
#  * (test-rolling-upgrade-final-upload.sh) - Download the six inline, remote, and multisegment files from the previous two steps using the main uplink and old satellite api.
