Description _nobody_ 2017-07-11 09:02:30 UTC
Let me start from GNOME on Xorg as an architecture.

We see that in Xorg server space we have two processes working independently. We have Xorg server as one process (which also does logging built-in services), and we have aside second independent process which is Xorg compositor itself.

These two processes (Xorg server and its compositor) communicate (probably) via D-bus, my best guess?!
_______

Let me now change the topic. Let me talk about Wayland clients, and Wayland, and its server (called Weston). Here, we have completely different situation, as my best understanding is. Talking about Wayland + Weston architecture.

We have Weston as server, and Wayland as a protocol that specifies the communication between Weston and its clients. I assume, single (Wayland + Weston) process after all. And, we do NOT have logger, as we have it in Xorg server.

Major/critical question: why we don't have logging services/logger in Weston?

[1] Because the execution timing is tight?
[2] Real Time is compromised?
[3] You, Weston developers, name it for me/us all?! 

In other words I am advocating for the logger (similar to one in Xorg server, which creates Xorg.0.log files) to be created/designed and built-in inside/as part of Weston. 

Thank you,
_nobody_

I don't know why you're saying that Weston doesn't have logging output:

strictly:~% weston --log=weston.log
^C%                          
strictly:~% wc -l weston.log

I have not pasted the other 99 lines of log output. If you would like to try it for yourself, you can see that the log is really quite comprehensive. I still don't know what specific output you're looking for, but it is completely false that Weston 'does not have logging services/logger'.

And again, Weston has _nothing_ to do with GNOME. Nothing at all. If you have problems with GNOME Wayland, _please take it up with GNOME_. We cannot help you with GNOME bugs or feature requests. This is not the GNOME Bugzilla. We are not GNOME developers. Nothing we do here will solve your problems with GHOME.

I'll totally ignore this comment. It is given at the wrong Time, at the wrong Place.

This is much better answer. I'll experience this one (although I NEEDED to install Weston package):

 [root@localhost ~]# dnf install weston-1.12.0-6.fc26.x86_64

The question is: why I needed to install it? It should be part of GNOME/Weston deal, as my best understanding is??? And what really I did install?

Thank you,

Comment 4 Daniel Stone 2017-07-11 12:08:00 UTC
GNOME does not use Weston.

Weston is a Wayland server, which offers a desktop environment.

GNOME Shell (internally using Mutter) is also a Wayland server, which offers a desktop environment.

If you do not understand that your request for better logging in the GNOME session must be made to the GNOME developers, then the comment was completely in the right time and the right place.

This bug tracker is not for discussion of GNOME issues. Logging inside GNOME is a GNOME issue, and not a Wayland issue.

End of topic, thankyou.
