lpstat output is read synchronously #21

Closed juhaerk closed 6 months ago

juhaerk commented 3 years ago

This extension appears to read the output from "lpstat" (opened through spawn_async()) synchronously. In case cupsd and thus lpstat is slow to respond, this causes Gnome UI hangs.

This can be reproduced for example by replacing /usr/bin/lpstat with a shell script that only does "sleep 30". Gnome will then hang for 30 seconds each time the extension is reading printer information.
