Provide an option to stop the computer when all downloads are completed

[Julien Cornuwel]

Not a bug but a feature request. Title is pretty self-explanatory I think.

Hi Julien,

Thanks for you feature request! I'll try to implement this, but I can't promise it will be included in a future release, because I need approval from Severin. When I know more, I'll let you know (which should be tomorrow).

[Severin H (severinh)]

Hi Marcel and Julien,

SABnzbd already provides this feature, which means that we won't need to do anything except designing and implementing an UI for it. And this can be done easily.

It's probably a good idea to implement it as a plug-in.

[Julien Cornuwel (julien-cornuwel)]

Thanks guys, it would be nice. I would have proposed a patch but I'm python-phobic ;-)

[Sander Tuit (avirulence)]

What's not to like about python? No strange brackets at all! ;-)

we may want to provide an option to either shutdown the pc or just shutdown lottanzb and sadnzbd. looking at the sabnzbd api, the shutdown option shut down sabnzbd and not the computer, right?

[Julien Cornuwel (julien-cornuwel)]

@ Sander : Sorry for hurting your pythonist feelings. Was just trolling to hide the fact that I never took the time to learn it, which I often regret.

[Severin H (severinh)]

I should have spend more time investigating the issue.

SABnzbd actually provides a feature that allows one to execute a certain action when SABnzd finishes downloading the whole queue. One of the predefined actions is "shutdown_pc". This action can even be specified through the API (have a look at 'ChangeCompleteActionQuery' in LottaNZB's code).

The problem is that it won't work on Linux as the system_* functions in sabnzbd/__init__.py have not been implemented for Linux, but only Windows ans Mac OS X (Darwin?). I guess one would need to get in touch with the SABnzbd devs so that the Linux-specific code can be written before 0.5 is released.

[Severin H (severinh)]

I don't see why we should provide SABnzbd's feature that shuts it down as soon as the queue has been downloaded completely.

Marcel just pointed out that it's not possible to shut down the system without root privileges. This might be the reason why the SABnzbd devs didn't implement it for Linux machines. Is there really no way of shutting down a Linux machine without root privileges? What happens if I shut down my machine from the GNOME panel?

[Eran C (shush6)]

Marcel is right that you can't shut down the system using the shutdown command without root privileges. GNOME panel shut down the system by contacting a daemon with root privileges via DBUS.

So in Gnome (and I think it will also work in KDE) you can shutdown the system by calling the shutdown method on this DBUS Service: org.freedesktop.PowerManagement

code should look something like these:

objectPath = '/org/freedesktop/PowerManagement'
busName = 'org.freedesktop.PowerManagement'
bus = dbus.SessionBus()
pm = bus.get_object(busName, objectPath)
pm.Shutdown()

other methods available are:Hibernate() ,Suspend(), Reboot()

haven't tested it yet because then I couldn't complete this message :) but it should work... problem is that it might not work on other Desktop envierments.

[Eran C (shush6)]

for some reason the code I wrote isn't working, but don't know much about DBUS so with little modifications it should work

[Severin H (severinh)]

I also supposed that it's possible to achieve it using DBus. A problem is that the power management Dbus API changed alot lately, probably because of the HAL deprecation. We actually had a plug-in ready for 0.5.2 which used the power management API (prevent system hibernation) but I removed it again when I noticed that it just wouldn't work on Ubuntu 9.10.

[Marcel de Vries (carresmd-deactivatedaccount)]

There are several ways to shutdown the system using DBus, via ConsoleKit,
PowerManager and probably DeviceKit. Last night I only researched the
ConsoleKit way and managed to shutdown my system. I will write a patch for
SABnzbd later today. Probably using all methods to shutdown the system, that
way it should work on most systems. I believe PowerManager is going to be
depricated as it depends on hal, IIRC.

I have submitted my patch to the SABnzbd developers. It is likely it will be included in the 0.5 release of SABnzbd :-). If you want to you can see the forum post here: http://forums.sabnzbd.org/index.php?topic=2635.0

[Marcel de Vries (carresmd-deactivatedaccount)]

The patch has been implemented by the SABnzbd developers. :-)

[Severin H (severinh)]

Just merged a new plug-in into the 0.5 series branch that prevents the computer from being suspended while LottaNZB is still downloading. Depending on what time has been chosen in the GNOME preferences after which the computer is treated to be idle, the computer will then be suspended automatically.
