cc8d318aa1 transaction: make transaction collapsing smarter with > 2 views
Sway maintains a list of pending transactions, and tries to merge
consecutive transactions applying to the same views into one. Given
a pending transactions list on views {A, B, C} of:

  A -> A' -> A'' -> B -> B' -> B''

Sway will collapse the transactions into just A'' -> B''. This works
fine when doing things like resizing views by their border. However,
when interactively resizing layouts like H[V[A B] C], we end up with
pending transaction lists like:

  A -> B -> C -> A' -> B' -> C' -> A'' -> B'' -> C''

Previously, Sway would not be able to simplify this transaction list,
and execute many more transactions than would be necessary (the final
state is determined by {A'', B'', C''}).

After this commit, the transaction list gets simplified to A'' -> B'' ->
C'', resolving performance problems (that were particularly noticeable
with high-refresh-rate mice).

Fixes #5736.

8355884fbd transaction: validate X transaction completions by geometry, not size
Xwayland views are aware of their coordinates, so validating transaction
completions should take into account the reported coordinates of the
view. Prior to this commit they didn't, and matching dimensions would
suffice to validate the transaction.

Also introduced `transaction_notify_view_ready_immediately` to support
the fix from d0f7e0f without jumping through hoops to figure out the
geometry of an `xdg_shell` view.

5bd6a5ce3f transaction: don't reconfigure X views unless integral coords changed
Sway logical coordinates are doubles, but they get truncated to integers
when sent to Xwayland through `xcb_configure_window`. X11 apps will not
respond to duplicate configure requests (from their truncated point of
view) and cause transactions to time out.

Fixes #5035.

d0f7e0f481 transaction: Mark client resize immediately ready
If a client commits a new size on its own, we create a transaction for
the resize like any other. However, this involves sending a configure
and waiting for the ack, and wlroots will not send configure events when
there has been no change. This leads to transactions timing out.

Instead, just mark the view ready immediately by size when the client
is already ready, so that we avoid waiting for an ack that will never
come.

Closes: https://github.com/swaywm/sway/issues/5490

fcd0ab8f33 view: Save all buffers associated with view
During the execution of a resize transaction, the buffer associated
with a view's surface is saved and reused until the client acknowledges
the resulting configure event.

However, only one the main buffer of the main surface was stored and
rendered, meaning that subsurfaces disappear during resize.

Iterate over all, store and render buffers from all surfaces in the view
to ensure that correct rendering is preserved.

d9de5b8758 Implement inhibit_idle command
This implements the following command to set/unset a user idle
inhibitor for a view:
`inhibit_idle focus|fullscreen|open|none|visible`

The modes are as follows:
- focus: inhibited when the view is focused by any seat
- fullscreen: inhibited when the view is fullscreen (or a descendant of
  a fullscreen container) and is visible on any output
- open: inhibited until the view is closed or the inhibitor is unset or
  changed
- none: unsets any user set idle inhibitors for the view
- visible: inhibited when the view is visible on any output

This should have no effect on idle inhibitors set by the applications
themselves and those should still work as intended.

Since this operates on the view in the handler context, it is possible
to set it on the currently focused view, on any existing view with
criteria, or for any future view with for_window.

0a9ff774ad Center surface inside container when it's too small
The goal here is to center fullscreen views when they are both too small
for the output and refuse to resize to the output's dimensions. It has
the side effect of also centering the view when it's too small for its
container.

Example clients that have this behaviour are emersion's hello-wayland
and weston.

It works by introducing surface_{x,y,width,height} properties to the
container struct. The x and y represent layout-local coordinates where
the surface will be rendered. The width and height are only used to
track the surface's previous dimensions so we can detect when the client
has resized it and recenter and apply damage accordingly.

The new surface properties are calculated when a transaction is applied,
as well as when a view resizes itself unexpectedly. The latter is done
in view_update_size. This function was previously restricted to views
which are floating, but can now be called for any views.

For views which refuse to resize *smaller* than a particular size, such
as gnome-calculator, the surface is still anchored to the top left as
per the current behaviour.

1211a81aad Replace wlr_log with sway_log
This commit mostly duplicates the wlr_log functions, although
with a sway_* prefix. (This is very similar to PR #2009.)
However, the logging function no longer needs to be replaceable,
so sway_log_init's second argument is used to set the exit
callback for sway_abort.

wlr_log_init is still invoked in sway/main.c

This commit makes it easier to remove the wlroots dependency for
the helper programs swaymsg, swaybg, swaybar, and swaynag.

ed5aafd90b Refactor seat operations to use an interface
This splits each seat operation (drag/move tiling/floating etc) into a
separate file and introduces a struct sway_seatop_impl to abstract the
operation.

The move_tiling_threshold operation has been merged into move_tiling.

The main logic for each operation is untouched aside from variable
renames.

The following previously-static functions have been made public:
* node_at_coords
* container_raise_floating
* render_rect
* premultiply_alpha
* scale_box

* sway_view.{x,y,width,height} ->
sway_container.content_{x,y,width,height}
    * This is required to support placeholder containers as they don't
    have a view.
* sway_container_state.view_{x,y,width,height} ->
sway_container_state.content_{x,y,width,height}
    * To remain consistent with the above.
* sway_container_state.con_{x,y,width,height} ->
sway_container_state.{x,y,width,height}
    * The con prefix was there to give it contrast from the view
    properties, and is no longer useful.

renamed to container_set_geometry_from_content.

60a1d79de7 Rebase the cursor after applying transactions
This approaches cursor rebasing from a different angle. Rather than
littering the codebase with cursor_rebase calls and using transaction
callbacks, this just runs cursor_rebase after applying every transaction
- but only if there's outputs connected, because otherwise it causes a
crash during shutdown.

There is one known case where we still need to call cursor_rebase
directly, and that's when running `seat seat0 cursor move ...`. This
command doesn't set anything as dirty so no transaction occurs.

bdae625cb3 Rebase the cursor after mapping a view
I originally put the rebase at the end of view_map, but at this point
the view is still at its native size and will ignore the motion event if
it falls outside of its native size. The only way to do this properly is
to rebase the cursor later - either after sending the configure, after
the view commits with the new size, or after applying the transaction. I
chose to do it after applying the transaction for simplicity.

I then attempted to just call cursor_rebase after applying every
transaction, but this causes crashes when exiting sway (and possibly
other places) because cursor_rebase assumes the tree is in a valid
state.

So my chosen solution introduces transaction_commit_dirty_with_callback
which allows handle_map to register a callback which will run when the
transaction is applied.

c006717910 Minor refactor of input manager
The input manager is a singleton object. Passing the sway_input_manager
argument to each of its functions is unnecessary, while removing the
argument makes it obvious to the caller that it's a singleton. This
patch removes the argument and makes the input manager use server.input
instead.

On a similar note:

* sway_input_manager.server is removed in favour of using the server
global.
* seat.input is removed because it can get it from server.input.

Due to a circular dependency, creating seat0 is now done directly in
server_init rather than in input_manager_create. This is because
creating seats must be done after server.input is set.

Lastly, it now stores the default seat name using a constant and removes
a second reference to seat0 (in input_manager_get_default_seat).

7b138e5ef0 Add CSD to border modes
This replaces view.using_csd with a new border mode: B_CSD. This also
removes sway_xdg_shell{_v6}_view.deco_mode and
view->has_client_side_decorations as we can now get these from the
border.

You can use `border toggle` to cycle through the modes including CSD, or
use `border csd` to set it directly. The client must support the
xdg-decoration protocol, and the only client I know of that does is the
example in wlroots.

If the client switches from SSD to CSD without us expecting it (via the
server-decoration protocol), we stash the previous border type into
view.saved_border so we can restore it if the client returns to SSD. I
haven't found a way to test this though.

7586f150c0 Implement type safe arguments and demote sway_container
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.

b12f7be907 Don't use bitfield to test for similar transactions
When there's multiple transactions in the queue, sway can take a
shortcut by checking if they all operate on the same set of containers.
If they do, it can skip all but the last transaction. The way we tested
for transactions which used the same containers was to exclusive-or
their con IDs together, but this has proved not only to be ineffective
but also has the potential to make sway crash.

This patch replaces the exclusive-or with a loop and container
comparison.

b6058703fa Refactor destroy functions and save workspaces when there's no outputs
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.

Send enter/leave events for floating views
2018-08-19 22:06:09 -04:00
Ryan Dwyer
0f6d212629 Send output enter/leave events correctly
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.

This commit makes it continue to hold the buffer if the view is

2b5a404ac9 Replace hacky L_FLOATING container with a list
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).

1801b725e2 Add using_csd variable to transaction state
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

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.

e7a7306063 Don't progress transaction queue if any are partially complete
This fixes an issue where views might commit to a transaction ahead of
the first one, and applying the first transaction causes us to save a
buffer of the wrong size.
