Database corruption during shutdown, GUI gone.

[Daniel Schürmann]

During Mixxx shutdown the database is synced back into the hdd, during this time, the Mixxx GUI is already gone.

If you restart, kill, umount or power down during this time, there is a big risk for DB corruption especially if it is located on an external media.
(Just happens to me)

We should pop up a window, displaying "clean up dB" or something reasonable, to clarify this state.

I have assigned this to 1.12, since loosing the DB is one of the bad things.
On my eeePC using and a > 10k tracks library it took 35 s until Mixxx displays a GUI and 110 s from closing the GUI to final exit Mixxx.

it sounds like you removed a device without ejecting it properly. Whether mixxx has exited is irrelevant... you could remove the device and the data might not have been synced anyway. So it seems like adding an exit screen doesn't solve the problem.

I guess this is "fixed" now because we don't hide the gui until the program has exited?

[Daniel Schürmann (daschuer)]

Actually it is fixed twice. We do not hide the gui and we have solved all known situations that have delayed the shutdown.
If we still experience a slow shutdown in a specific situation. (will be now an undesired gui leak during Shutdown) We should open a new bug. Mixxx should shutdown almost instantly.
