From c3ef36d6b5d36f783f41b8860cee321b652f91e3 Mon Sep 17 00:00:00 2001 From: Ryan Dwyer Date: Wed, 15 Aug 2018 10:03:55 +1000 Subject: Simplify transactions Commit 4b8e3a885be74c588291c51f798de80bd81a92db makes it so only one transaction is committed (ie. configures sent) at a time. This commit removes the now-unnecessary code which was used to support concurrent committed transactions. * Instead of containers storing a list of instructions which they've been sent, it now stores a single instruction. * Containers now have an ntxnrefs property. Previously we knew how many references there were by the length of the instruction list. * Instructions no longer need a ready property. It was used to avoid marking an instruction ready twice when they were in a list, but this is now avoided because there is only one instruction and we nullify the container->instruction pointer when it's ready. * When a transaction applies, we no longer need to consider releasing and resaving the surface, as we know there are no other committed transactions. * transaction_notify_view_ready has been renamed to view_notify_view_ready_by_serial to make it consistent with transaction_notify_view_ready_by_size. * Out-of-memory checks have been added when creating transactions and instructions. --- sway/tree/root.c | 2 -- 1 file changed, 2 deletions(-) (limited to 'sway/tree/root.c') diff --git a/sway/tree/root.c b/sway/tree/root.c index 79f2194e..068e7911 100644 --- a/sway/tree/root.c +++ b/sway/tree/root.c @@ -26,7 +26,6 @@ void root_create(void) { root_container.type = C_ROOT; root_container.layout = L_NONE; root_container.name = strdup("root"); - root_container.instructions = create_list(); root_container.children = create_list(); root_container.current.children = create_list(); wl_signal_init(&root_container.events.destroy); @@ -55,7 +54,6 @@ void root_destroy(void) { free(root_container.sway_root); // root_container - list_free(root_container.instructions); list_free(root_container.children); list_free(root_container.current.children); free(root_container.name); -- cgit v1.2.3
