Because C++ exceptions escaping into C FFI invokes undefined behaviour
our Wayland implementation wraps all the interface vtable callbacks
with try {} catch (...) { log_error }.This has the nice property of not crashing the server, but does result in the client and server having different ideas about the current state. In the interests of debugability it would be nice to tell clients that their request failed due to server error rather than silently continue into unknown territory. These patches introduce a WL_DISPLAY_ERROR_INTERNAL error the compositor can send in such cases. _______________________________________________ wayland-devel mailing list wayland-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/wayland-devel
