Custom notification settings

[sempasha]

Since webapp .desktop file contains X-GNOME-UsesNotifications=true you can set custom notification settings for each web application. But it doesn't work because of mismatch between notification desktop-entry tag and application .desktop file name.

My case:

1. I have a Google Play Music application
2. .desktop file at ~/.local/share/applications/ has name Google Play Music-webpin.desktop
3. I have notifications configuration for this app to show only bubbles without sound
4. Capturing application's notifications with dbus-monitor --session shows, that notification, created by application, looks like

   method call time=1555098482.534859 sender=:1.430 -> destination=org.freedesktop.Notifications serial=21 path=/org/freedesktop/Notifications; interface=org.freedesktop.Notifications; member=Notify
   string ""
   uint32 0
   string ""
   string "War Pigs"
   string "Black Sabbath - Paranoid"
   array [
     string "app.open-web-app('https://play.google.com/music/listen')"
     string "Open Google Play Music"
   ]
   array [
     dict entry(
        string "desktop-entry"
        variant             string "a4af67a.artemanufrij.webpin"
     )
     dict entry(
        string "urgency"
        variant             byte 1
     )
     dict entry(
        string "image-path"
        variant             string "/home/sempasha/.cache/com.github.artemanufrij.webpin/Google Play Music"
     )
   ]
   int32 -1

5. When notification captured by pantheon notifications widget widget tries to find application info by searching .desktop file. For search it uses desktop-entry tag, so search always failed, because .desktop file name Google Play Music-webpin.desktop is not match desktop-entry tag value a4af67a.artemanufrij.webpin
6. Due to notification widget can't find app info it uses default notifications settings

Renaming .desktop file to a4af67a.artemanufrij.webpin.desktop solves the issue.

At GNOME Goal: Notification Sources said

desktop_id should be the basename of the applications desktop file. E.g. rhythmbox installs /usr/share/applications/rhythmbox.desktop, so the desktop_id should be "rhythmbox".

So pantheon notifications widged do its job exactly as it should.

In my view gnome goal sheets miss one thing - <desktop-entry>.desktop should allow not only to make a statement, that application supports notifications, but also to specify identifier which application will use for notifications.

Nonetheless, for now the only way to fix notifications is to specify <desktop-entry>.desktop file name in way, when <desktop-entry> is same as desktop-entry property of notification.
