Create locking on experimental flow -----------------------------------

Key: OVIRT-899 URL: https://ovirt-jira.atlassian.net/browse/OVIRT-899 Project: oVirt - virtualization made easy Issue Type: Task Reporter: Gil Shinar Assignee: infra

In order to make experimental flow atomic, we need to do as follows: in deploy.sh script and in start_testing_latest.sh we need to add a loop in the beginning of each script that does the following: *while 1: do is_locked=$((echo aaa > my.lock) 2> /dev/null || echo is locked) if [[ -z $is_locked ]]; then break else sleep 5 fi done* Wrap the whole script with a trap so in the end if each script we will be able to remove my.lock no matter what happened.
