Progress bar hangs at 100% after download is finished, while installing

[Manuel de la Peña]

When a user installs a new click packages the following steps ocurr (internally)

1. Download application.
2. Check the click package checksum
3. Launch click and install the application.

Unfortunately the preview just shows the progress up to the end of step 1. Steps 2 and 3 might take some time and the user will be left with no feed back of what is going on. The u-d-m has bug 1248770 about to be fixed and will make fixing this issue easier. Ideally when the processing signal is raised the progress bar should be set to the indeterminate state (http://developer.ubuntu.com/api/devel/ubuntu-13.10/qml/ui-toolkit/qml-ubuntu-components0-progressbar.html#indeterminate-prop) and a string should show what is going on.

[Mike McCracken (mikemc)]

NOTE: in the cases where an app is being installed when the scope receives a request for a preview for it (ie, when you click install then close the preview, then go back to the preview after a download but before the install is done) -

The scope gets the object path from UDM to send to the preview, so it can be notified when it's done - however if the progress is already at 100%, no progress signal will be sent and the value will appear to be zero.

There appears to be some work to do in the DownloadTracker code so the progress bar can be displayed as indeterminate initially in that case.

Why is this against unity8? Isn't this responsability of unity-scope-click?

[dobey (dobey)]

This belongs against unity8 as it's where the implementation of the widget is, which listens for the dbus signals. The scope has no direct way to control the UI, and may not even be running when the signal is sent.
