flatpak portal example on github

[Winnie Poon]

Hi all,

that would be sad news 🙁  I remember a while ago when I asked in this mailing list about usb drive access, a few developers including Alex suggested the device portal, that's why I looked into that, but now it seems like --device=all is the ONLY option?

So really my approach of using file chooser to grant permission to the right file e.g. /dev/bus/usb/001/010 would not go anywhere?  like even after if i can somehow solve the root owner issue?

I'm really hoping to have a better solution than using --device=all. 🙁

Regards,
Winnie

Hi

Perhaps it would be relevant to mention this issue?: https://github.com/flatpak/xdg-desktop-portal/issues/228

Surely the issue is that there currently is no portal for block device access, which is why people recommend --device=all as a workaround.

My attempt of using the portal is to avoid using the blanket type access --device=all.

From my previous inquiries here, i was told that using the portal would be an alternative way to avoid opening up all device access.

It looks like i just need to use GTK file chooser to open up access to a particular path in /dev/bus/usb/....  the fact that the file's owned by root may make it a bit tricky, but i'm sure i should still be able to access it in the sandbox?

Much appreciated any suggestions you may have.

Thanks,
Winnie

If you're accessing USB devices you might be better off with the --device=all permission.

Hi,

i'm trying to use the GTK file chooser approach to access the usb mass storage (/dev/bus/usb/...), the filechooser can see the path and file, but it sees the file size as zero, probably because it's owned by root?

how do i use the portal to access a file like this?

Thanks,
Winnie

Just to clarify, i'm referring to USB mass storage here.

Thanks again.

Hi,

Would like to ask similar question for usb drive access.

Is it the org.freedesktop.portal.Device that's supposed to be used for granting usb drive permission?

I'm having trouble finding the gtk API for that.  If anyone can point me to the reference, that'll be much appreciated.

Many many thanks again.

Winnie
