I have been searching trying to discover why so many of my 42.3 applications fail in leap 15. As a test I rebooted my system so things would be fresh, and then executed: pstree -p -n With Thunderbird, Firefox, Rhythmbox, fvwm2, a terminal an a few others, there were 438 different processes spawned. Just Firefox was responsible for 238 processes. Rhythmbox, one of my problem apps, had 10 processes. I would like to find documentation describing how one would write an application and all of the synchronization requirements linked by gdbus and the other protocols. I am currently rereading the systemd documentation which gives some of the desired information at startup. What I would like is a document that ended with a cookbook giving a full example of an application. For example a simple window with a push button in it. I am sure people do write code for opensuse, or else we wouldn't need such a software development environment. The only documentation I can find relates to setting up the environment and system management. Thanks, and it doesn't have to be free. I will buy a book if available.
