Barak Korren commented on OVIRT-899:
------------------------------------
As we've talked, the code will probably work better over time if the loop is not
infinite, like so:
{code}
MAX_LOCK_ATTEMPTS=120
LOCK_WAIT_INTERVAL=5
LOCK_PATH=$HOME/experimental_repo.lock
wait_for_lock() {
trap "rm -f '$LOCK_PATH'" EXIT
for ((i = 0; i < $MAX_LOCK_ATTEMPTS; i++)); do
(set -o noclobber; > $LOCK_PATH) 2> /dev/null && return
sleep $LOCK_WAIT_INTERVAL
done
echo "Timed out waiting for lock" >&2
exit 1
}
{code}
Create locking on experimental flow
-----------------------------------
Key: OVIRT-899
URL: https://ovirt-jira.atlassian.net/browse/OVIRT-899
Project: oVirt - virtualization made easy
Issue Type: Task
Reporter: Gil Shinar
Assignee: infra
In order to make experimental flow atomic, we need to do as follows:
in deploy.sh script and in start_testing_latest.sh we need to add a loop in the beginning
of each script that does the following:
*while 1:
do
is_locked=$((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.
