From 563b23a33726289387193b85d90fb569631ee05f Mon Sep 17 00:00:00 2001 From: Berke Güzel Date: Tue, 13 Oct 2026 23:52:22 +0300 Subject: Reconnect to a restarted Wayland compositor Windows now outlive the compositor. On connection loss YASL sends DISPLAY_LOST instead of closing every window, retries the connection on a loop timer, rebuilds each toplevel with its title, size, state and GL context, and sends DISPLAY_RESTORED. CPU windows keep their pixels; GPU renderers drop Vulkan surfaces and GL objects on loss and rebuild them on restore. - Free the dead connection's objects on the next wait, after the application has released GPU objects built on them. - Report a lost connection as an event rather than a failed wait. - Refuse window and Vulkan surface creation while offline with the new YASL_ERROR_DISCONNECTED. - Close popups, cancel drags and fail pending clipboard requests on loss. - Print only protocol errors, not ordinary disconnects. - Examples survive a restart; game.c rebinds its GL context. - Add an end-to-end test that kills Weston under CPU, GL and Vulkan windows and requires them to recover.
