From 2032f85d94f2f222282b242116b3e827dd458f6c Mon Sep 17 00:00:00 2001 From: Ryan Dwyer Date: Sat, 14 Jul 2018 23:14:55 +1000 Subject: Simplify transactions by utilising a dirty flag on containers This PR changes the way we handle transactions to a more simple method. The new method is to mark containers as dirty from low level code (eg. arranging, or container_destroy, and eventually seat_set_focus), then call transaction_commit_dirty which picks up those containers and runs them through a transaction. The old methods of using transactions (arrange_and_commit, or creating one manually) are now no longer possible. The highest-level code (execute_command and view implementation handlers) will call transaction_commit_dirty, so most other code just needs to set containers as dirty. This is done by arranging, but can also be done by calling container_set_dirty. --- sway/desktop/transaction.c | 35 +++++++++++++++++------------------ 1 file changed, 17 insertions(+), 18 deletions(-) (limited to 'sway/desktop/transaction.c') diff --git a/sway/desktop/transaction.c b/sway/desktop/transaction.c index 2b3f87c3..d7ef7130 100644 --- a/sway/desktop/transaction.c +++ b/sway/desktop/transaction.c @@ -47,7 +47,7 @@ struct sway_transaction_instruction { bool ready; }; -struct sway_transaction *transaction_create() { +static struct sway_transaction *transaction_create() { struct sway_transaction *transaction = calloc(1, sizeof(struct sway_transaction)); transaction->instructions = create_list(); @@ -141,23 +141,8 @@ static void copy_pending_state(struct sway_container *container, } } -static bool transaction_has_container(struct sway_transaction *transaction, +static void transaction_add_container(struct sway_transaction *transaction, struct sway_container *container) { - for (int i = 0; i < transaction->instructions->length; ++i) { - struct sway_transaction_instruction *instruction = - transaction->instructions->items[i]; - if (instruction->container == container) { - return true; - } - } - return false; -} - -void transaction_add_container(struct sway_transaction *transaction, - struct sway_container *container) { - if (transaction_has_container(transaction, container)) { - return; - } struct sway_transaction_instruction *instruction = calloc(1, sizeof(struct sway_transaction_instruction)); instruction->transaction = transaction; @@ -285,7 +270,7 @@ static bool should_configure(struct sway_container *con, return true; } -void transaction_commit(struct sway_transaction *transaction) { +static void transaction_commit(struct sway_transaction *transaction) { wlr_log(WLR_DEBUG, "Transaction %p committing with %i instructions", transaction, transaction->instructions->length); transaction->num_waiting = 0; @@ -418,3 +403,17 @@ struct wlr_texture *transaction_get_saved_texture(struct sway_view *view, *height = instruction->saved_buffer_height; return instruction->saved_buffer->texture; } + +void transaction_commit_dirty() { + if (!server.dirty_containers->length) { + return; + } + struct sway_transaction *transaction = transaction_create(); + for (int i = 0; i < server.dirty_containers->length; ++i) { + struct sway_container *container = server.dirty_containers->items[i]; + transaction_add_container(transaction, container); + container->dirty = false; + } + server.dirty_containers->length = 0; + transaction_commit(transaction); +} -- cgit v1.2.3
