Hi all, Since some time I’m working on ivi-shell to add xdg-protocol support by means of libweston-desktop. Due to my changes both xdg-protocol applications and ivi-shell / ivi-application-protocol applications are supported within ivi-shell now. The known functionality is preserved and just extended by a further protocol. The advantage is that client applications do not need to be edited to generate an id and are also not limited to use the custom ivi-application protocol anymore, since the ids are handled by an id agent inside of weston now.
As a preparation for the changes the goto labels in ivi-shell have been reworked to avoid memory leaks. In ivi-layout I added an interface (ivi_layout_surface_set_id) to set the surface-id of an ivi-layout-surface. It can be done once after being created by an xdg-protocol application to assign a numeric id by means of an id agent for example. Additionally I introduced a new event to notify about a desktop surface being configured (desktop_surface_configured). An id agent can register to this event and react to this accordingly by assigning an id by means of ivi_layout_surface_set_id. As a result I also changed the test client applications in the Weston repository and removed the ivi-application protocol support since that has only been used, if xdg protocol is not supported. Finally hmi-controller has been edited to accept desktop surfaces. There are some things that can be done in the future: At first it would be diligent, if hmi-controller would also use xdg protocol for the GUI itself. Then also the surface_configure event could be removed from hmi-controller. Secondly the weston unit tests should also test the interface changes for surface_set_id and also should stop using the ivi-application protocol. Thanks for reading and questions are very welcome. [changes version 2] Adjustments have been done according to Quentin Glidic's remarks. * weston_desktop_surface_create_view is used to create a view for toplevel desktop surfaces * weston_desktop_surface_unlink_view is used to destroy a view for toplevel desktop surfaces * weston_desktop_surface_set_user_data and weston_desktop_surface_get_user_data() are used instead of loops Thanks for your review.
