Hello,
As you all may know, xdg-shell v5 and xdg-shell stable can't currently
co-exist in the same compositor, as both define structures with the same
name (such as struct xdg_surface_interface).
A solid effort was made to add functionality to wayland-scanner to
resolve this, but turned out to be a Very Hard Problem:
https://lists.freedesktop.org/archives/wayland-devel/2018-January/036549.html
Is a good summary of where that patch series currently sits.
That leaves us with a bit of a problem - weston currently support
xdg-shell v5, and that's blocking any chance of adopting xdg-shell final.
It's my opinion that supporting xdg-shell final is rather important for
the wayland reference compositor.
So, I think we need to consider removing xdg-shell v5 from weston and
its included clients as soon as is reasonable.
It should probably be considered deprecated since the introduction of
xdg-shell v6 into wayland-protocols in late 2015. I'm sure there are
still users out there, but it has always been labeled "unstable" with a
firm promise that it would disappear eventually.
Do we have any opinions on when we can strip this out? I think keeping
it for the next release and removing it immediately after is pragmatic
(with a firm warning in the release notes that this is coming).
Myself, I'd be happy to start drafting patches to remove it immediately
- weston isn't intended to be anyone's desktop, so I don't think
arguments that some released software will fail to run on weston should
be given substantial weight...
Also, I don't think toytoolkit clients failing to connect to a
compositor that only has v5 support is a major concern either.
Thanks,
Derek
