snapd doesn't parse INI group in autostart file

[Ilya Fedin]

Let's say we have such a .desktop autostart file:

[Desktop Entry]
Name=Telegram Desktop
Comment=Official desktop version of Telegram messaging app
TryExec=/snap/telegram-desktop/x7/usr/bin/telegram-desktop
Exec=/snap/telegram-desktop/x7/usr/bin/telegram-desktop -workdir /home/ilya/snap/telegram-desktop/common/ -autostart
Icon=${SNAP}/meta/gui/icon.png
Terminal=false
StartupWMClass=TelegramDesktop
Type=Application
Categories=Chat;Network;InstantMessaging;Qt;
MimeType=x-scheme-handler/tg;
Keywords=tg;chat;im;messaging;messenger;sms;tdesktop;
Actions=Quit;
SingleMainWindow=true
X-GNOME-UsesNotifications=true
X-GNOME-SingleWindow=true

[Desktop Action Quit]
Exec=/snap/telegram-desktop/x7/usr/bin/telegram-desktop -workdir /home/ilya/snap/telegram-desktop/common/ -quit
Name=Quit Telegram
Icon=application-exit

The expected result is snapd will use Desktop Entry/Exec command, the actual result is it uses Desktop Action Quit/Exec command leading to application not starting

Hi Ilya, can you please tell me how to reproduce the issue?

snapd is not starting applications itself; do you mean to say that the .desktop file generated by snapd contains the wrong commands?

snap userd --autostart command is a part of snapd, right? If yes then it does.

No, I set the apps.<app-name>.autostart to a .desktop file name and then the application creates a .desktop file with such name in $SNAP_USER_DATA/.config/autostart, with the content I provided in first message.

Try to use the apps.<app-name>.autostart feature with a .desktop file with multiple INI groups, like e.g. the one I provided.

It just goes in a loop splitting the lines by "=" rather than using a proper INI parser and getting proper keys from the "Desktop Entry" group
