We cannot change the signature of the release event, and we cannot add another event to wl_buffer because wl_buffer has several unrelated factories, which makes extending wl_buffer interface in particular impossible. Using serials would also require extending wl_surface.attach somehow carry a serial in the first place. Client side reference counting, that is, for every committed attach there will be a release, seems like the preferred solution to me at the moment. I've forgot the details related to the possibility of implementing wl_proxy_get_version(), but from what I recall, it should be perfectly doable since we already have runtime object version inheritance in libwayland-client (don't we?).</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
