From 9b15e81cff62eb214c89f62bc9e499c7f21d86cf Mon Sep 17 00:00:00 2001 From: Ryan Dwyer Date: Mon, 25 Jun 2018 16:41:31 +1000 Subject: Fix potential crash when fullscreen view unmaps It happened when a view is a grandchild or deeper of the workspace, is fullscreen, and unmaps. The workspace would not be included in the transaction and its pointer to the fullscreen view was left dangling. --- sway/tree/view.c | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) diff --git a/sway/tree/view.c b/sway/tree/view.c index cb36f123..2ca0dbbb 100644 --- a/sway/tree/view.c +++ b/sway/tree/view.c @@ -542,14 +542,16 @@ void view_map(struct sway_view *view, struct wlr_surface *wlr_surface) { struct sway_container *view_unmap(struct sway_view *view) { wl_signal_emit(&view->events.unmap, view); + wl_list_remove(&view->surface_new_subsurface.link); + wl_list_remove(&view->container_reparent.link); + if (view->is_fullscreen) { struct sway_container *ws = container_parent(view->swayc, C_WORKSPACE); ws->sway_workspace->fullscreen = NULL; + container_destroy(view->swayc); + return ws; } - wl_list_remove(&view->surface_new_subsurface.link); - wl_list_remove(&view->container_reparent.link); - return container_destroy(view->swayc); } -- cgit v1.2.3-70-g09d2
