novenary dbc326ba84 Don't apply hide_edge_borders to any floating container
This fixes the following scenario:
- Place a floating window so its border is right at the edge of the
  screen
- Create a new split
- The border disappears
- Moving the window does not restore the border

Ragnar Groot Koerkamp d5c71231e5 Only call workspace_auto_back_and_forth when needed
Instead of disabling it for some workspace subcommands, this explicitly
calls it only in the 2 places it's actually needed: for switching to a
named or numbered workspace.

Ragnar Groot Koerkamp 3080f1b9ce Move auto_back_and_forth logic out of workspace_switch
This extracts the code to a separate workspace_auto_back_and_forth
function.
It also removes the bool argument by adding an extra if statement at the call
site, and repurposes the no_auto_back_and_forth variable to
auto_back_and_forth for simpler understanding.

Ragnar Groot Koerkamp 771cff23fb Fix #6299 Disable auto_back_and_forth for next_on_output
This forces no_auto_back_and_forth to true for `workspace
next_on_output` and `workspace prev_on_output` to keep parity with i3.
In i3, running next_on_output never changes focus to another output.
In Sway currently, with workspace_auto_back_and_forth set to yet,
running next_on_output on an output with only a single active workspace
will typically end up focussing the other output:
1. next_on_output focusses the current workspace, because it's the only
one
2. auto_back_and_forth focusses the last focussed workspace, because the
current workspace to focus is the current one. This will usually be on
the other monitor if the workspace there was last focussed.

Daniel Eklöf 3bf99198a6 sway: restore SIGPIPE handler before exec:ing swaybar
Sway ignores SIGPIPE (by installing a SIG_IGN handler), in order to
“prevent IPC from crashing Sway”.

SIG_IGN handlers are the *only* signal handlers inherited in
sub-processes. As such, we should be a good citizen and restore the
SIGPIPE handler to its default handler.

Daniel Otero b997147284 config: Fix swaybar pango_markup inconsistency

Bill Doyle cad6e59b93 Only defer seat attachment during initial startup
Deferred commands are only run once, during sway startup. This means
that deferring seat attachment based on whether we are reading the
config prevents devices from being reattached to the correct seat during
a config reload. Instead, only defer if the config is not yet active.

Fixes #6048.

tomKPZ f9a5c18c93 Add tab dragging functionality
Implements functionality described in [1].  Please see the issue for a
video with a demonstration of the new behavior.

An issue is that titlebars cover up a significant portion of the top
edge drop area.  The solution is simply to change the edge drop area
hitbox to start at the contents instead of the container.

Kenny Levinsen 4e6f515253 desktop/render: Pass explicit clip box to render
render_surface_iterator previously deduced the clip box from an optional
container passed with render data. This causes problems when offsets in
view geometry need to be compensated for in the clip dimensions.

Instead, prepare the clip box in render_view_toplevels where the offsets
are being applied, and compensate for them immediately.

A similar compensation is applied to render_saved_view.

Kenny Levinsen 7ec9d07fc5 Remove usage of surface->sx|sy
These coordinates contain the all-time accumulated buffer attach point,
which is a way to perform incremental client-side initiated movement of
windows, intended as a way to maintain logical window positioning while
compensating for layout changes such as folding in a left side panel.

This value is not useful for implementing this feature, and break things
if they ever become non-zero. Their inclusion in calculations also tend
to cause confusion.

Remove usage of these coordinates, removing the ability for clients to
move themselves. This may again be supported if a better API is made
available from wlroots.

Michael Weiser 730efbc89c Prevent use-after-free on first bar subcommand error
If any error is encountered during execution of the first subcommand of
a freshly created bar configuration, parsing apparently is to be aborted
and the current bar config is freed. The pointer to that memory is left
dangling though, leading to a use-after-free on successive bar
subcommands. This quite reliably ends in a crash like so:

sway -c reproducer.config
00:00:00.083 [sway/config.c:865] Error on line 2 'foo bar': Unknown/invalid command 'foo' (s)
free(): double free detected in tcache 2
00:00:00.608 [swaynag/swaynag.c:451] failed to register with the wayland display
Aborted (core dumped)

Minimal reproducer config:
bar {
        foo bar
        position top
}

Other messages:
malloc(): unaligned fastbin chunk detected
double free or corruption (fasttop)

The invalid command has to be the first for a newly created bar config.
Removing the command or switching order so it's not the first one masks
the problem.

Prevent this from occuring by resetting the pointer to NULL after
freeing the memory.

Kenny Levinsen 152a559e30 idle_inhibit: Store wlr inhibitor instead of view
When an application inhibited idle, a view pointer was stored and a
destroy listener was registered to the wlr inhibitor. As the wlr
inhibitor lives longer than the view, this lead to a dangling view
pointer between view unmap and inhibitor destroy.

Store a pointer to the wlr inhibitor instead of to the view, and look up
the view when needed, which may at any point be NULL. This also allows
for an inhibitor to remain functional if a surface is re-mapped.

Add view_container_content_at for use in the focused container fast path
which only tests container content area, and fall back to full workspace

Kenny Levinsen d358aab8d9 container: Limit tiled focus to container geometry
container_at would maintain the current focus as long as a position was
over one of the container view's surfaces. If an oversized surface was
being clipped, this lead to weird focus behavior.

Instead, use view_container_at for this test, which intersects the
container box before looking at surfaces.

ftilde 1afedcb94c Fix for_window criteria and mouse button bindings
Previously, the special case handling of scratchpad and unmark commands
was (probably accidentally) limited to criteria directly handled in the
execute_command function. This would exclude: 1. for_window criteria, as
these are handled externally for views and 2. and mouse bindings which
select target the node currently under the mouse cursor.

As a concrete example `for_window [app_id="foobar"] move scratchpad,
scratchpad show` would show (or hide due to the toggling functionality)
another window from the scratchpad, instead of showing the window with
app_id "foobar".

This commit replaces the "using_criteria" flag with "node_overridden"
with the more general notion of signifying that the node (and
container/workspace) in the current command handler context of the sway
config is not defined by the currently focused node, but instead
overridden by other means, i.e., criteria or mouse position.

Quantum e01a3c85f6 render: handle containers without output when rendering titles
In e0a94bee8d, it was believed that if the
container is being rendered, it must have an output.

This turned out not to be the case. When rendering a container, all its
children are rendered, even if the children is positioned off screen and
thus not having any output. This is the cause of the crash in #6061.

This commit introduces a null-check, which fixes #6061.

Tadeo Kondrak bb41b7b814 output: Reconfigure xcursor when applying output config
Before this commit, when an output had its scale dynamically changed,
Sway would not load a cursor theme with the new scale. This results
in stale cursor images when moving the cursor into an area controlled
by the compositor, like the background or resize areas.

To reproduce:
- Using IPC, set an output scale to a value that isn't currently used
- Move the cursor into a compositor-controlled area
- The cursor will not change

view_child_init was calling view_init_subsurfaces, which did not set the

acting as standalone children. If the parent was an xdg_popup, this

When a container straddles multiple outputs, the title bar is only rendered

In this commit, we take into consideration the scale the title was rendered
at and scale it accordingly so that it appears at the right size on the other
outputs.

Kenny Levinsen c8bf84c82d transactions: Amend pending transactions
The transaction system contains a necessary optimization where a popped
transaction is combined with later, similar transactions. This breaks
the chronological order of states, and can lead to desynchronized
geometries.

To fix this, we replace the queue with only 2 transactions: current and
pending. If a pending transaction exists, it is updated with new state
instead of creating additional transactions.

As we never have more than a single waiting transaction, we no longer
need the queue optimization that is causing problems.

Ronan Pigott 8eb0c54693 introduce workspace_squash
workspace_squash is container_flatten in the reverse
direction. Instead of eliminating redundant splits that are
parents of the target container, it eliminates pairs of
redundant H/V splits that are children of the workspace.

Splits are redundant if a con and its grandchild have the
same layout, and the immediate child has the opposite split.

For example, layouts are transformed like:

    H[V[H[app1 app2]] app3] -> H[app1 app2 app3]

i3 uses this operation to simplify the tree after moving
heavily nested containers to a higher level in the tree via
an orthogonal move.

This change allows any client commit to change its surface geometry,

Tudor Brindus 0df5753aed input/seatop_default: consider fullscreen views to have no edges
Previously, `find_edge` on a single fullscreen view would occasionally
return an edge rather than `WLR_EDGE_NONE`. This would trigger entry
into `seatop_resize_tiling`, which doesn't have meaning for a fullscreen
view.

The result was that the fullscreen container hitbox was considered to be
that of where it'd be if it were tiling, so most clicks would not go
through.

Fixes #5792.

mwenzkowski 4799cb0960 output: Revert implementation of evacuate_sticky()
The function evacuate_sticky() was changed in commit 32788a93 to be used
by workspace_for_each_container() to make the code more readable. But I
overlooked that it is not safe to use workspace_for_each_container() to
remove container from a workspace. This commit restores the previous
implementation for evacuate_sticky().

Dimitris Triantafyllidis 39328ca4e4 In container_split, set a floating container's view to tiled
Currently, when a floating container with a view is split and
children are added to it, the new views are rendered as tiled,
while the first view stays in floating style.

Here this is addressed by setting the view to tiled as soon
as the container is split, by duplicating the "view part" of
the logic in container_set_floating(..., false). Since the new
container of the view is no longer considered floating, it
makes sense to set the view to tiling at this point.

The view would have to be set back to floating if it was possible
to "unsplit" the container.

mwenzkowski 32788a93f2 output: evacuate sticky containers only if new output has a workspace

Dimitris Triantafyllidis 0cb9282aee Smart borders fix: always show borders for floating containers
Currently, in view_autoconfigure, the only condition for show_border
is !view_is_only_visible. view_is_only_visible does not cross the
boundary between the workspace's tiling and floating lists and does not
differentiate between them.

The result is, that in a workspace with zero or more tiling containers
and a single floating container, the floating container will lose its
borders as soon as it is split, provided that a only one view is visible
within the floating container.

Fixed by adjusting the condition for show_borders.

Tudor Brindus 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.

Brian Ashworth 2ea5d2985a input/libinput: remove input type property bias
This changes it so all libinput config options are set on any device
that supports it. Previously, only a subset of libinput config options
were being considered depending on the input type. Instead of trying to
guess which properties the device may support, attempt to set any
configured property regardless of the device type. All of the functions
already have early returns in them for when the device does not actually
support the property. This brings the configuration side inline with
describe_libinput_device for the IPC side. This change was prompted
by a tablet tool showing the calibration matrix property in the IPC
message, but not being able to actually change it since that property
was only being considered for the touch input type.

Simon Ser 5432f00adf config/output: don't change output state before commit
Previously, we called output_disable prior to wlr_output_commit. This
mutates Sway's output state before the output commit actually succeeds.
This results in Sway's state getting out-of-sync with wlroots'.

An alternative fix [1] was to revert the changes made by output_disable
in case of failure. This is a little complicated. Instead, this patch
makes it so Sway's internal state is never changed before a successful
wlr_output commit.

We had two output flags: enabled and configured. However enabled was set
prior to the output becoming enabled, and was used to prevent the output
event handlers (specifically, the mode handler) from calling
apply_output_config again (infinite loop).

Rename enabled to enabling and use it exclusively for this purpose.
Rename configure to enabled, because that's what it really means.

Johan Bjäreholt 1f8dbb320a tree/view: Make foreign-toplevel app_id fallback to class
It is not a part of the foreign-toplevel-management protocol to get the
class of a toplevel, only for getting the app_id.
For xwayland clients this is an issue because that means that you cannot
identify what application the toplevel refers to which is the point of
the app_id property.

By falling back to class when an app_id does not exist solves this problem.

Phoc also uses app_id and class interchangeably in their implementation
of foreign-toplevel-management, in fact they always do that and not only
for just this protocol.

wlr_drag installs grabs for the full duration of the drag, leading to

If a client commits a new size on its own, we create a transaction for

Instead, just mark the view ready immediately by size when the client

Tudor Brindus d328c2439c input/pointer: don't trigger pointer bindings for emulated input
Prior to this commit, a tablet device could trigger mouse button down
bindings if the pen was pressed on a surface that didn't bind tablet
handlers -- but it wouldn't if the surface did bind tablet handlers.

We should expose consistent behavior to users so that they don't have to
care about emulated vs. non-emulated input, so stop triggering bindings
for any non-pointer devices.

Tudor Brindus 82c439c4f1 input/cursor: send idle events based off device type, not input type
Previously, a tablet or touch device could report activity as a pointer
device if it went through pointer emulation. This commit refactors idle
sources to be consistently reported based on the type of the device that
generated an input event, and now how that input event is being
processed.

Tudor Brindus 20deb8ec16 input/tablet: focus appropriate node on tip down
This commit makes tablet input more usable when `focus_follows_mouse` is
set to `no`.

Previously, tapping down on surfaces that bound tablet input would not
switch focus, whereas tapping on surfaces that didn't (and hence went
through pointer emulation) did.

Brian Ashworth 33aa59d4c6 input/keyboard: wlr_keyboard_group enter and leave
This adds support for wlr_keyboard_group's enter and leave events. The
enter event just updates the keyboard's state. The leave event updates
the keyboard's state and if the surface was notified of a press event
for any of the keycodes, it is refocused so that it can pick up the
current keyboard state without triggering any keybinds.

If a resize is triggered on a tabbed or stacked container, change focus
to the tab which already had inactive focus, rather than to the tab
whose border was clicked -- otherwise, we'd change the active tab when
the user probably just wanted to resize.

This commit makes `get_current_time_msec` correctly return milliseconds

we don't lose occasionally go back in time by one second. Finally, the
function is moved into `util.c` so that it can be reused elsewhere
without having to consider these pitfalls.

Thomas Hebb 84ec8f92a6 Use new wlroots API for clearing keyboard/pointer focus during grabs
We are not allowed to do what we did in #5222 and pass a `NULL` surface
wlr_seat_pointer_notify_enter(), and it's causing crashes when an
xdg-shell popup is active (see #5294 and swaywm/wlroots#2161).

Instead, solve #5220 using the new wlroots API introduced in
swaywm/wlroots#2217.

Kenny Levinsen 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.

Tudor Brindus 6ea45395c7 input/pointer: send pointer enter event on confine warp
The spec has this to say about sending events on confine creation:

  Whenever the confinement is activated, it is guaranteed that the
surface the pointer is confined to will already have received pointer
focus and that the pointer will be within the region passed to the
request creating this object.

...and on region update:

  If warped, a wl_pointer.motion event will be emitted, but no
wp_relative_pointer.relative_motion event.

Prior to this patch, sway did neither, and updated the hardware cursor
position without notifying the underlying surface until the next motion
event. This led to inconsistent results, especially in applications that
draw their own software cursor.

Tudor Brindus 5d13f647f9 input/tablet: add seatop_down entry for tablet input
Currently, when tablet input exits a window during an implicit grab, it
passes focus to another window.

For instance, this is problematic when trying to drag a scrollbar, and
exiting the window &mdash; the scrollbar motion stops. Additionally,
without `focus_follows_mouse no`, the tablet passes focus to whatever
surface it goes over regardless of if there is an active implicit.

If the tablet is over a surface that does not bind tablet handlers, sway
will fall back to pointer emulation, and all of this works fine. It
probably should have consistent behavior between emulated and
not-emulated input, though.

This commit adds a condition for entering seatop_down when a tablet's
tool tip goes down, and exiting when it goes up. Since events won't be
routed through seatop_default, this prevents windows losing focus during
implicit grabs.

Closes #5302.
