I can provide travis builds where the event is never fired. But that is in a situation where something is going very wrong to cause such. It should not happen normally. The odd thing is even when it hangs, it seems the correct process is ended. Just log output stops, as does other function execution.

I added log statements to see this, I can show in travis builds and code. You can see the pid from callack here, this is fired from ECORE_EXE_EVENT_DEL https://github.com/Obsidian-StudiosInc/entrance/blob/master/src/daemon/entrance.c#L311 I also added pid logging just after ecore_exe_pipe_run https://github.com/Obsidian-StudiosInc/entrance/blob/master/src/daemon/entrance.c#L297 > ii) is entrance_client really existing ? looks like the xserver died > before the child died, i would not wonder if that causes some > confusion that leaves some x call stuck on a lock or something. I think there is a problem with initialization. I am not seeing the necessary communication between client and server. It never makes it this far, and that first part is likely pretty crucial. INF<13012>:entrance ../src/daemon/entrance_server.c:18 _entrance_server_add() server client connected INF<13012>:entrance ../src/daemon/entrance_server.c:19 _entrance_server_add() Sending users INF<13012>:entrance ../src/daemon/entrance_server.c:24 _entrance_server_add() Sending actions INF<13012>:entrance ../src/daemon/entrance_server.c:30 _entrance_server_add() Sending xsessions .... That likely means the client and server are not communicating. So the cilent maybe ending, but its not properly interacting with the server process. Which remains, and X process gets orphaned. Keep something in mind, this is all specific to the Travis env. I do not experience any of these issues in actual usage on real systems. Though it could be related to some other issues I do experience. Also not sure if systemd is causing things to behave differently. -- William L. Thomson Jr.
