2018-09-05Implement type safe arguments and demote sway_containerRyan Dwyer
This commit changes the meaning of sway_container so that it only refers to layout containers and view containers. Workspaces, outputs and the root are no longer known as containers. Instead, root, outputs, workspaces and containers are all a type of node, and containers come in two types: layout containers and view containers. In addition to the above, this implements type safe variables. This means we use specific types such as sway_output and sway_workspace instead of generic containers or nodes. However, it's worth noting that in a few places places (eg. seat focus and transactions) referring to them in a generic way is unavoidable which is why we still use nodes in some places. If you want a TL;DR, look at node.h, as well as the struct definitions for root, output, workspace and container. Note that sway_output now contains a workspaces list, and workspaces now contain a tiling and floating list, and containers now contain a pointer back to the workspace. There are now functions for seat_get_focused_workspace and seat_get_focused_container. The latter will return NULL if a workspace itself is focused. Most other seat functions like seat_get_focus and seat_set_focus now accept and return nodes. In the config->handler_context struct, current_container has been replaced with three pointers: node, container and workspace. node is the same as what current_container was, while workspace is the workspace that the node resides on and container is the actual container, which may be NULL if a workspace itself is focused. The global root_container variable has been replaced with one simply called root, which is a pointer to the sway_root instance. The way outputs are created, enabled, disabled and destroyed has changed. Previously we'd wrap the sway_output in a container when it is enabled, but as we don't have containers any more it needs a different approach. The output_create and output_destroy functions previously created/destroyed the container, but now they create/destroy the sway_output. There is a new function output_disable to disable an output without destroying it. Containers have a new view property. If this is populated then the container is a view container, otherwise it's a layout container. Like before, this property is immutable for the life of the container. Containers have both a `sway_container *parent` and `sway_workspace *workspace`. As we use specific types now, parent cannot point to a workspace so it'll be NULL for containers which are direct children of the workspace. The workspace property is set for all containers, except those which are hidden in the scratchpad as they have no workspace. In some cases we need to refer to workspaces in a container-like way. For example, workspaces have layout and children, but when using specific types this makes it difficult. Likewise, it's difficult for a container to get its parent's layout when the parent could be another container or a workspace. To make it easier, some helper functions have been created: container_parent_layout and container_get_siblings. container_remove_child has been renamed to container_detach and container_replace_child has been renamed to container_replace. `container_handle_fullscreen_reparent(con, old_parent)` has had the old_parent removed. We now unfullscreen the workspace when detaching the container, so this function is simplified and only needs one argument now. container_notify_subtree_changed has been renamed to container_update_representation. This is more descriptive of its purpose. I also wanted to be able to call it with whatever container was changed rather than the container's parent, which makes bubbling up to the workspace easier. There are now state structs per node thing. ie. sway_output_state, sway_workspace_state and sway_container_state. The focus, move and layout commands have been completely refactored to work with the specific types. I considered making these a separate PR, but I'd be backporting my changes only to replace them again, and it's easier just to test everything at once.
2018-08-26Remove layout.cRyan Dwyer
When we have type safety we'll need to have functions for workspace_add_tiling and so on. This means the existing container functions will be just for containers, so they are being moved to container.c. At this point layout.c doesn't contain much else, so I've relocated everything and removed the file. * container_swap and its static functions have been moved to the swap command and made static. * container_recursive_resize has been moved to the resize command and made static. * The following have been moved to container.c: * container_handle_fullscreen_reparent * container_insert_child * container_add_sibling * container_add_child * container_remove_child * container_replace_child * container_split * enum movement_direction and sway_dir_to_wlr have been moved to util.c. Side note: Several commands included layout.h which then included root.h. With layout.h gone, root.h has to be included by those commands.
2018-08-26Make separate gaps functions per container typeRyan Dwyer
In preparation for using type safety.
2018-08-25Relocate container_move, container_move_to and container_get_in_directionRyan Dwyer
* container_move is only called from the move command * container_move_to was called from both the move command and the sticky command, but the sticky command can easily not call it * container_get_in_direction is only called from the focus command Moving these functions to their respective commands gives better separation of code and removes bloat from layout.c. These functions will need to be refactored to take advantage of type safety, so separating them will make this easier to refactor. The following static functions have also been moved: * is_parellel * invert_movement * move_offs * container_limit * workspace_rejigger * move_out_of_tabs_stacks * get_swayc_in_output_direction They were all used by the move functions, except for the last one which is used by focus. Other changes: * index_child has been renamed to container_sibling_index, moved to container.c and made public * sway_output_from_wlr has been renamed to output_from_wlr_output, moved to output.c and made public * container_handle_fullscreen_reparent has been made public * sway_dir_to_wlr has been made public No changes have been made to any of the moved functions, other than updating calls to functions that have been renamed.
2018-08-24Refactor destroy functions and save workspaces when there's no outputsRyan Dwyer
This changes the destroy functions to the following: * output_begin_destroy * output_destroy * workspace_begin_destroy * workspace_destroy * container_begin_destroy * container_destroy * view_begin_destroy * view_destroy The terminology was `destroy` and `free`, and it has been changed to `begin_destroy` and `destroy` respectively. When the last output is disconnected, its workspaces will now be stashed in the root. Upon connection of a new output they will be restored. There is a new function `workspace_consider_destroy` which decides whether the given workspace should be destroyed or not (ie. empty and not visible). Calling container_begin_destroy will no longer automatically reap the parents. In some places we want to reap the parents and in some we don't, so this is left to the caller. container_reap_empty_recursive and container_reap_empty have been combined into one function and it will recurse up the tree.
2018-08-20Fix crash when adding outputRyan Dwyer
2018-08-20Send output enter/leave events correctlyRyan Dwyer
Previously we used a reparent event to detect when a view changes parent, then sent an output enter/leave to the surfaces if needed. This worked for tiling views but not floating views, as floating views can intersect another output without changing parent. The solution implemented for floating views also applies cleanly to tiling views, so the previous method has been completely replaced and the reparent event has been removed. This introduces a new function container_discover_outputs. This function compares the container's `current` position to the outputs, sends enter and leave events as needed, and keeps track of which outputs it's intersecting in a new `container->outputs` list. If it has entered a new output with a different scale then the title and marks textures will also be recreated at the new scale. The function is called when a transaction applies. This is convenient as it means we don't have to call it from various places. There is imperfect rendering when a floating view overlaps two outputs with different scales. It renders correctly for the most recently entered output, but there is only one title texture so it renders incorrectly on the old output. Fixes #2482
2018-08-19Replace hacky L_FLOATING container with a listRyan Dwyer
Workspaces previously had a magical `workspace->floating` container, which had a layout of L_FLOATING and whose children were actual floating views. This allowed some conveniences, but was a hacky solution because the container has to be exempt from focus, coordinate transactions with the workspace, and omit emitting IPC events (which we didn't do). This commit changes it to be a list directly in the sway_workspace. The L_FLOATING layout is no longer used so this has been removed as well. * Fixes incorrect check in the swap command (it checked if the containers had the L_FLOATING layout, but this layout applied to the magical container). * Introduces workspace_add_floating
2018-08-18Implement iterators per container typeRyan Dwyer
This introduces the following `for_each` functions: * root_for_each_workspace * root_for_each_container * output_for_each_workspace * output_for_each_container * workspace_for_each_container And introduces the following `find` functions: * root_find_output * root_find_workspace * root_find_container * output_find_workspace * output_find_container * workspace_find_container * container_find_child And removes the following functions: * container_descendants * container_for_each_descendant * container_find This change is preparing the way for demoting sway_container. Eventually these functions will accept and return sway_outputs, sway_workspaces and sway_containers (meaning a C_CONTAINER or C_VIEW). This change also makes it easy to handle abnormalities like the workspace floating list, root's scratchpad list and (once implemented) root's saved workspaces list for when there's no connected outputs.
2018-08-18Rename container_sort_workspaces and container_wrap_childrenRyan Dwyer
This commit renames container_sort_workspaces to output_sort_workspaces and moves it to output.c. This also renames container_wrap_children to workspace_wrap_children and moves it to workspace.c. This function is only called with workspaces.
2018-08-17Add using_csd variable to transaction stateRyan Dwyer
This fixes a race condition flicker when unfloating a view which uses client side decorations. When the view is floated it has using_csd = true, so the decorations are not drawn. When unfloating it it changes to false, but this change wasn't part of transactions so it could potentially render the decorations around the view while it's waiting for the transaction to apply.
2018-08-15Simplify transactionsRyan Dwyer
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.

Remove container_for_each_descendant_bfs
2018-08-11Remove container_for_each_descendant_bfsRyan Dwyer
The function was not used. Also renames container_for_each_descendant_dfs to just container_for_each_descendant.
2018-08-11Remove container_has_childRyan Dwyer
In all cases you can use container_has_ancestor with the arguments swapped, which is faster than container_has_child.
2018-08-08Fix edge cases when moving floating container to new workspaceRyan Dwyer
* Removes container_floating_move_to_container, instead opting to put that logic in container_move_to * In the seat code, focusing a floating view now updates the pending state only and lets the next transaction carry it over to the current state. This is required, otherwise it would crash. * When unfullscreening a floating container, an output check is now done to see if it should center it.

2018-08-06commands: fix layout implementation (also better name for previous split layout)Ian Fan
2018-08-03Fix crash when moving cursor over a fullscreen split containerRyan Dwyer
Calling container_at_view fails an assertion if the container isn't a view. Calling tiling_container_at works correctly, as that function checks if the container is a view and calls container_at_view if so.

2018-07-31Fix popupsRyan Dwyer
Fixes the render and container_at order for popups. Fixes #2210 For rendering: * render_view_surfaces has been renamed to render_view_toplevels * render_view_toplevels now uses output_surface_for_each_surface (which is now public), as that function uses wlr_surface_for_each_surface which doesn't descend into popups * Views now have a for_each_popup iterator, which is used by the renderer to render the focused view's popups * When rendering a popup, toplevels (xdg subsurfaces) of that popup are also rendered For sending frame done, the logic has been updated to match the rendering logic: * send_frame_done_container no longer descends into popups * for_each_popup is used to send frame done to the focused view's popups and their child toplevels For container_at: * floating_container_at is now static, which means it had to be moved higher in the file. * container_at now considers popups for the focused view before checking containers. * tiling_container_at has been introduced, so that it doesn't call container_at recursively (it would check popups recursively if it did)
2018-07-30Fix title textures on scale changeBrian Ashworth
2018-07-28Allow containers to floatRyan Dwyer
Things worth noting: * When a fullscreen view unmaps, the check to unset fullscreen on the workspace has been moved out of view_unmap and into container_destroy, because containers can be fullscreen too * The calls to `container_reap_empty_recursive(workspace)` have been removed from `container_set_floating`. That function reaps upwards so it wouldn't do anything. I'm probably the one who originally added it... * My fix (b14bd1b0b1536039e4f46fe94515c7c44e7afc61) for the tabbed child crash has a side effect where when you close a floating container, focus is not given to the tiled container again. I've removed my fix and removed the call to `send_cursor_motion` from `seat_set_focus_warp`. We should consider calling it from somewhere earlier in the call stack.

2018-07-22Implement floating_modifier and mouse operations for floating viewsRyan Dwyer
This implements the following: * `floating_modifier` configuration directive * Drag a floating window by its title bar * Hold mod + drag a floating window from anywhere * Resize a floating view by dragging the border * Resize a floating view by holding mod and right clicking anywhere on the view * Resize a floating view and keep aspect ratio by holding shift while resizing using either method * Mouse cursor turns into resize when hovering floating border or corner
2018-07-16Mark containers as urgent in IPC if they have urgent viewsRyan Dwyer
2018-07-15Make focus part of transactionsRyan Dwyer
Rather than maintain copies of the entire focus stack, this PR transactionises the focus by introducing two new properties to the container state and using those when rendering. * `bool focused` means this container has actual focus. Only one container should have this equalling true in its current state. * `struct sway_container *focus_inactive_child` points to the immediate child that was most recently focused (eg. for tabbed and stacked containers).
2018-07-14Simplify transactions by utilising a dirty flag on containersRyan Dwyer
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.
