Nothing is saved

[jdstrand]

Hi,

I'm really excited to start using this app on Ubuntu Touch, but nothing is saved. Steps to reproduce: open the app, create a project, close the app, open the app, the project that was added is missing.

At first I thought it was because application confinement was blocking access to the ubuntu-tasks.db, but I worked around that in apparmor-easyprof-ubuntu 1.0.31 in Ubuntu. I'm using ubuntu-tasks 0.5.1 on Ubuntu Touch (mako/Nexus 4). There are no apparmor denials now so it shouldn't be a permissions problem. I even uninstalled ubuntu-tasks, removed the ubuntu-tasks.db, installed 0.5.1 anew and tried again-- still didn't work (again, no apparmor denials and ubuntu-tasks.db was created successfully).

As an aside-- currently ubuntu-tasks.db is being written out to ~/.local/share/Qt Project/QtQmlViewer/ubuntu-tasks.db because of LP: #1224126. As mentioned, I have currently worked around this in Ubuntu, but this path will not be allowed for much longer. If you are able, I recommend you change the path to your database to be ~/.local/share/com.ubuntu.developer.mdspencer.ubuntu-tasks/ubuntu-tasks.db to avoid migration problems on upgrades. You may want to comment in the bug how this is affecting your app. See https://wiki.ubuntu.com/SecurityTeam/Specifications/ApplicationConfinement#Application_environment for details.

Unfortunately, I tried using the path your recommended and it doesn't work. The ~ is not turned into my user directory, but instead the whole path is created as a directory structure under ~/.local/share/Qt Project/QtQmlViewer.

So do you know if this is a bug in my app or a problem with the phone/SDK?

I just figured out that this is due to a bug in the SDK preventing Component.onDestruction from being called when the app is stopped.

The SDK is not using the correct path. That is this bug:
https://bugs.launchpad.net/ubuntu/+source/u1db-qt/+bug/1224126

I suggest that you comment there saying that you are trying to use the correct
paths but the SDK is preventing you from doing so.

Cool, I look forward to the fix! You're app looks very useful. :)

I've partially fixed this by using a Timer which saves the app's data every 5 seconds. Hopefully that is short enough that the user won't loose anything and long enough to not influence the app's performance.

This could influence the app's performance and the lifecycle of the flash-memory. I'd like your great app so much, that I would love to see another solution...

[iBelieve]

@ingmar- I'd love another solution, but can't think of anything that would work. I tried saving everything whenever something was changed, but that resulting in the app freezing when it would load. Do you have any suggestions?

[iBelieve]

This was fixed (properly) a long time ago.
