Dear All,


I have backported following patches from wayland 1.11.0 to 1.9.0 to
test one crash issue [1] . I am able to backport and start Weston with
it. Is this valid thing to do?

[client: Introduce proxy wrappers]

[client: Fix wl_display_roundtrip_queue() race condition]

[tests/queue-test: Add tests for proxy wrappers] -- not required.



Now If I understand it correctly I need to use/modify code where the
wayland client creates the proxy and sets the queue. One such
components is [2] ILM control library. I tried to do as per the
patches but with it nothing is coming on display even though weston
starts successfully with ivi-shell and ivi-controller.so.


Attached here the modified file. I would like to understand if the
way I used is correct or not? Could someone explain this fix and How
to use it properly for ILM control library? Do I need to add similar
fix in qtwayland  5.5.1 and other such components (e.g. wayland sink
from gstreamer) ?
