Background portal

[joshuamegnauth54]

Requires the access portal to be enabled or else it does nothing

I based my implementation on the official specs as well as code from GNOME, KDE, Xapp (Xfce), and Pantheon (elementary). KDE's immaculately readable codebase served as this implementation's primary inspiration.

Like KDE, I intend to show a dialog, so the user may choose whether to grant privileges to an application. I will also provide an option to bypass the dialog for greater choice especially considering that GNOME automatically grants permissions.

According to the docs, the Autostart method is deprecated. However, I think I still need to implement it because background requests aren't routed to the COSMIC portal unless it's available. Autostart is implemented

Closes: #49

[ids1024]

According to the docs, the Autostart method is deprecated. However, I think I still need to implement it because background requests aren't routed to the COSMIC portal unless it's available.

Looks like it was deprecated in May (https://github.com/flatpak/xdg-desktop-portal/commit/458560c768d5acf7e163ba57f219725294f5ff51) and the last release was in April. So presumably it's still required on released versions of xdg-desktop-portal, but won't in the next.

[joshuamegnauth54]

Their reasoning makes sense. Every portal backend I checked implements autostart the same way (which, in a way, was really nice because it made it easier to implement here :joy: ).

This is finally done and it works too! I learned a lot in the process as well.

Can't wait until this is approved!

Would this also fix cosmic-files not being able to supply files for flatpak uploads? For example: uploading a file using cosmic-file as picker in firefox (flatpak)

[joshuamegnauth54]

Nope! But I can try to look into that after finishing some other patches I'm working on. :smiley_cat:

The background portal allows sandboxed apps permission to run in the background without any windows open.

I'll try to provide logs to help with the implementation

Sounds good. I'll take a look into it soon. I can't guarantee I'll be able to fix it though. :laughing:

@gabriele2000 I'm not sure what's causing the permission errors. :thinking: The rest of the portal works, right? Like screenshots?

You should open an issue with the same log in case someone else knows, but I'll continue looking into it as well.

I hope the upgrade from 22.04 to 24.04 didn't mess something up too bad, because now the cursor in some flatpak apps is gigantic and there's this weird error. Anyway, one way to reproduce it is to use firefox (flatpak version) and try to upload a random file using cosmic-files (the picker is cosmic-files now)
