Delay shutdown until UbuntuOne has finished synchronizing

rated 0 times [ 3] [ 0] / answers: 1 / hits: 857 / 2 Years ago, fri, april 22, 2022, 8:43:30

when logging out to a different user, shutting down, or restarting the machine sometimes I can get this message

some programs are still running

program list

waiting for programs to finish. interrupting these programs may cause
you to lose work

Is there any way that ubuntu can automatically detect when these programs have completed their task before closing down?
I understand there is an issue with programs that might have crashed. But some other programs such as Ubuntuone might need some additional time to sync before the system can shutdown

Here you are, this is the parse output. I have got no clue of what can be done with it, but I am quite excited to see some magic!

martin@ubuntu-desktop:~$ u1sdtool --status

State: QUEUE_MANAGER

    connection: With User With Network

    description: processing the commands pool

    is_connected: True

    is_error: False

    is_online: True

    queues: IDDLE

the only difference when the daemon is syncing is the last line that can become

queues: WORKING

or

queues: WORKING_ON_BOTH

I am not sure if that would be nice, can you imagine if you had to w8 for 1Gb of files to be synced before shutdown? Doesn't it make more sense that the close signals are sent to the programs so they can quit and if there is further work then it can be resumed on after booting again.

Even Windows only allows 30 secs before it forces close on programs for shutdown.

I really don't see how can this be useful! If I order a shutdown I want that thing closed asap and boot up asap, not wait for the programs to do idontknowwhat. After all, it was my responsibility that started the shutdown, I should know when its a good time or not.

Edit (read all the comments bellow!):

Here is the script that checks the current status of UbuntuOne and shuts down only when status is idle.

#! /bin/bash



gracetime_given=false



while true; do

    u1sdtool_status=$(u1sdtool --status | grep -o 'queues: IDLE')

    timestamp=$(date +%H:%M:%S)

    if [ "$u1sdtool_status" = "queues: WORKING" -o "$u1sdtool_status" = "queues: WORKING_ON_BOTH" ]; then

        echo "$timestamp - UbuntuOne has not finished sync, waiting for conclusion."

        echo "Re-checking in 30 seconds."

        gracetime_given=false

        sleep 30

    elif [ "$u1sdtool_status" = "queues: IDLE" ]; then

        if [ $gracetime_given = false ]; then

            echo "u1sdtools seems to be idle at the moment..."

            echo "Giving u1sdtool some grace time, rechecking in 10 seconds."

            gracetime_given=true

            sleep 10

        else

            echo "This is where you shutdown!!!"

            sleep 5

            sudo shutdown -h now

        fi

    else

        echo "Something is really wrong!!!"

        break

    fi

done

To use it you need to do the following, on the terminal you need to use sudo visudo and add this line at the end of the file <yourusername> hostname=NOPASSWD: /sbin/shutdown -h now so that no password is necessary to shutdown your computer using account.

After that you need to save the script anywhere (), you need to use chmod 755 <nameofthescript.sh> to make it executable.

Then you can just run the scrip and see how it works:

gets the current status of UbuntuOne

if not idle re-checks to see if its idle every 30 secs

if idle will give it 10 more secs and recheck if the status is still idle

if it is still idle it will shutdown using shutdown -h now

Hope this works and comment as you want on the code as long as you understand that this is actually my very first bash script!
