The title itself and marks were being rendered by two very-similar yet
different functions, and any changes made to one had to be reflected on
the other.
This mostly prevents such oversights from happening, and keeps makes
sure we keep both consistent.
Use fixed titlebar heights. The default height is calculated based on
font metrics for the configured font and current locale.
Some testing with titles with emoji and CJK characters (which are
substantially higher in my setup) shows that the titlebars retain their
initial value, text does shift up or down, and all titlebars always
remain aligned.
Also drop some also now-unecessary title_height calculations.
Makes also needed to be updated, since they should be positioned with
the same rules.
Sometimes the preferred mode is not available due to hardware
constraints (e.g. GPU or cable bandwidth limitations). In these
cases it's better to fallback to lower modes than to end up with
a black screen.
When a layer surface shrinks we need to damage the area it previously
occupied, but we don't know the location of all its subsurfaces in the
previous state, so instead damage a rectangle that encloses the entire
previous extent.
The xdg-decoration protocol allows clients to request whether they want
to use server side decorations or client side decorations. Currently,
sway ignores this and always enforces whatever the server is currently
set to. Although tiled clients cannot be allowed to set borders, there
is no harm in listening requests from floating clients. Sidenote: also
fix an unrelated style error.
Losing the precision resulted in wlr_cursor and wlr_seat::pointer_state
getting out of sync during pointer motion in seatop_down.
Since the difference was always under 1 px, it was practically
impossible to notice in normal use.
But because of being out of sync, cursor_rebase would always end up
incorrectly calling wlr_seat_pointer_notify_motion from
seatop_default_begin (on releasing mouse button) which broke cursor
locking.
See #5405Closes#4632
When emulating touch, the simulating_pointer_from_touch field is
set to true. It's switched back to false when a touch_up event is
received. However we need to ensure we always send a wl_pointer.frame
event following a group of other wl_pointer events.
Since a touch_frame event is always guaranteed to come after a group
of touch events, unset simulating_pointer_from_touch in the touch_frame
handler instead of the touch_up handler. Add a new field to know whether
the touch_frame handler should stop emulation.
If HOME environment variable is not set, sway fails startup with a
segmentation fault due to null pointer dereference.
Also check calloc return value and only perform the fallback code when
really needed.

Add a subcommand for `gaps` that allows to toggle gaps at
runtime. This functionality is part of i3-gaps since [1]
but is missing in sway.

When setting the geometry from content for floating windows, the
coordinates for borders are normally taken into account. However in the
case of a floating fullscreen window, we should not be doing this. Since
the content of the container takes the space of the entire output, this
causes the calculated borders to neccesarily be outside of the output.
This later causes a problem when sending surface entrance events since
in a multi-monitor setup, the border coordinates will overlap with
another output despite the surface not actually being on that output at
all. The fix is to just ignore border coordinates for a floating
fullscreen container since fullscreen, of course, does not actually have
any borders. Fixes#6080.
get_current_time_msec is only used in cursor.c, so we can move it in and
make it static. This is primarily intended to avoid a symbol collision
with wlroots, which we unfortunately do not have a good solution for
yet.
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
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.
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.
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.
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.

Until now, swaybar did not have pango markup enabled by default, even if
the sway config had it on. This patch aims to mimic the i3 behavior, but
maintaining the functionality of the "pango_markup" sway config command.
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.
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.

There was some unused code-paths for rendering surfaces with an
arbitrary rotation applied. This was imported from rootston.
Since we don't have plans to make use of this, remove it.
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.
Closes: https://github.com/swaywm/sway/issues/6223
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.
remove view from its own unmap event listener so when subsurfaces
link try to remove themselves they won't run into it.

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)

Minimal reproducer config:
bar {

}
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.

the original behavior set fullscreen for all descendents of a container,
which causes issues when firefox is one of those children because it
sends its own set_fullscreen request in response to being fullscreened.
Can be useful to make sure a bugfix is included. In the future maybe
the wlroots version string could include a commit hash when built
from source, too.
When a tiling container is floated, the focus stack needs to be
appropraitely modified to return the container to its original
position in the tree upon floating disable, like i3.
Logic that obtains current DPMS state is put inside the handler.
sway_output from which the current DPMS state will be obtained is selected by the following logic:
* For '-' and '--' the focused output is used;
* For '*' error "Cannot apply toggle to all outputs" is reported;
* For everything else all_output_by_name_or_id() is used.
Fixes#5929.
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.
container_at checks if the position provided matches the currently
focused container with view_container_at as a fast path.
view_container_at checks using the main container geometry, which
includes the titlebar and border area. If a tabbed container is focused,
then positions over unfocused tabs are incorrectly reported as belonging
to the focused container, breaking focus on click.
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
scans for border and titlebar areas.
Closes: https://github.com/swaywm/sway/issues/6074
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.
If a surface is associated with a sway container, we limit the
destination box to the container dimensions.
Floating views and popups are exempt from this clipping.
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.
When issuing a focus command on a specific container, users expect to
proceed it even if is hidden by a fullscreen window.
This matches the behavior of i3.
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.
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
As of 66343839b1, sway now uses a
libdrm header. Add this dependency to the build system so headers from
it can be used on systems where pkg-config is required to find them.
On server request, we need to send configure events to inform the client
of the new intended size. If the client changes size itself, sending a
configure event will only cause problems.
Use transaction_commit_dirty_client to distinguish between the two
transaction causes.
Currently, various floating-point expressions involving
the coordinates of borders, titlebars and content surfaces
are directly assigned to integers, and so they are rounded
towards zero.
This results in off-by-one distances between these elements
when the signs of their coordinates differ.
Fixed by wrapping these expressions with a call to
floor before the assignment.
view_child_init was calling view_init_subsurfaces, which did not set the
parent attribute for the subchildren. This lead to the subchildren
acting as standalone children. If the parent was an xdg_popup, this
would make the subchild unaware of the popup position.
Introduce view_child_init_subsurfaces for view_child_init to use
instead.
Closes: https://github.com/swaywm/sway/issues/6038
The subchildren lose their parent association at this point, so they
will not be able to see that the parent is unmapped.
Instead, just set the subchildren to be unmapped directly.
When a container straddles multiple outputs, the title bar is only rendered
at the scale of the "effective" output. If the title bar straddles onto
another output with a different scale factor, it was drawn at the wrong size.
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.
This fixes#6054.
To reproduce:
- Open a floating window and a popup that hangs over the bottom or right
- Move the window in the direction of the popup overhang
- The previous position of the popup is damaged, not the new one
Pending state is currently inlined directly in the container struct,
while the current state is in a state struct. A side-effect of this is
that it is not immediately obvious that pending double-buffered state is
accessed, nor is it obvious what state is double-buffered.
Instead, use the state struct for both current and pending.
Every seat_set_focus* should be followed by a transaction_commit_dirty.
In cases where the focus change is followed by a seatop_begin* this is
not needed, as transaction_commit_dirty is then called by the
seatop_begin* function.
Fixes#6034
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.

Try to better mimic JSON node structure produced by i3 which might be
relied on by already existing tools. In particular having "type" right
after "id" is quite handy for streaming high-performance JSON parsers
such as simdjson (which are handy for maintaining responsiveness on
resource constrained systems).

Transactions currently wait for all configures to be acked, regardless
fo what they were sent to. This includes views that are hidden in tabbed
or stacked containers. If these views do not ack the configure in
response to a single frame callback, they can cause transaction
timeouts.
Check if a container is hidden before registering the configure serial
and saving any view buffers.
Closes: https://github.com/swaywm/sway/issues/6023
Before this commit, there would be cases where focus changes from one
window to another, the new window activates text_input, then the old
window sends a deactivate request, making text_input unfocused
completely.
There is no need to check for transactions at the end of every user
input, as the vast majority of input will not issue transactions. This
implementation can also hide where changes are made without an
appropriate transaction commit, as a future unrelated input would issue
the commit instead.
Instead, commit transactions in places where changes are made or are
likely to be made.
xdg_shell and xwayland handled geometry changes differently despite
needing mostly identical behavior. The xwayland implementation has been
changed to match that of xdg_shell.
The size of a tiled container cannot change in response to new buffer
sizes, so there is no need to commit a new transaction. Instead, simply
recenter the view with the new geometry, leaving the full transaction
flow for floating containers.
We need to use surface_x and surface_y when rendering and damaging saved
buffers as these compensate for views that have been centered due to
being smaller than their container.
Add them to the surface positions on the saved buffer so we have the
values from the time the buffer was saved.
Sway records pid, workspace, and output for every new process. However, if the
output gets disabled and the workspace disappears, the workspace is still
re-created on the disabled output. This commit adds a check for the enabled
flag, so that NULL will be passed to workspace_create() in this case.
wlr_output_configuration_head_v1_create normally fills out the head
"enabled" field to match the wlr_output state. We overwrite this to also
set the head as enabled if it is only turned off with DPMS.
However, in some cases we may not have a mode for this display, in which
case setting it as enabled will lead to a segfault later on. Therefore,
enabled conditional on the presence of a mode.
For certain applications (e.g. JetBrains) the parent window controls
input. We need to adhere to the ICCCM input focus specification to
properly handle these cases.

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 changes the move command to better match i3
behavior after the layout changes.
workspace_rejigger handled the case where containers would
escape their workspace in an orthogonal move by changing
the layout to accomodate them, but this case is now handled
within the loop.
In i3, the workspace_layout command does not affect the
workspace layout. Instead, new workspace level containers
are wrapped in the desired layout and the workspace layout
always defaults to the output orientation.
Some comparisons of current Sway versus i3 behavior:
1) T[T[T[app]]] + move left
* Sway: T[app]
* i3: T[T[app]]
2) H[V[H[V[app]]]] + move left
* Sway: H[app]
* i3: H[V[app]]
After this commit, Sway behavior matches i3. The intermediate states
are now:
T[T[T[app]]] -> T[T[app T[]]] -> T[T[app]]
H[V[H[V[app]]]] -> H[V[app H[V[]]]] -> H[V[app]]
In i3 the layout command on a workspace affects the workspace layout
only on empty workspaces. Otherwise children are placed in a new
container with the desired layout to preserve the workspace layout.
Instead of letting wlroots print messages to stdout, route debugging
messages into Sway's logging functions. This allows a more consistent
output (e.g. if Sway or wlroots changes its output style, they don't get
out-of-sync).
I also added a [wlr] prefix to wlroots messages, not yet sure it's a
good thing.
For each following combinations of criteria & command below, the command would
crash sway without the fix.
It's particular about the __focused__ criteria, where the view matches part of
the criteria but not the focused app, leading to a failure when calling
`strcmp` with NULL.
"xterm" is a non-wayland app (X11) and "kitty" is. Both are terminals.
# "class" is specific to X11
# The view is X11 (xterm) leading to the criteria checking for the
# focused app's class, leading to a crash
for_window [class="__focused__"] floating enable
exec kitty -e xterm
# Similarly, crash as the focused app (xterm) has no app_id when the view has one
for_window [app_id="__focused__"] floating enable
exec xterm -e kitty
# If the view has a title but not the focused app: NULL title will crash criteria checking
for_window [title="__focused__"] floating enable
exec xterm -title "" -e xterm
Currently, when sway sends a configure with some geometry and the
client responds with a different geometry in a commit that acks that
configure, sway ignores the new size. Sway applies the surface
geometry it had requested to the container, not what was actually
committed, in the following transaction.
This change allows any client commit to change its surface geometry,
even if it is a response to a configure event.
The keyboard group's effective keyboard layout was never being changed
due to a condition that incorrectly preventing it from being performed.
The IPC event that follows the change was correctly being prevented.
To query whether a container is sticky, checking `con->is_sticky` is
insufficient. `container_is_floating_or_child` must also return true;
this led to a lot of repetition.
This commit introduces `container_is_sticky[_or_child]` functions, and
switches all stickiness checks to use them. (Including ones where the
container is already known to be floating, for consistency.)
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.
When scrolling on a tabbed/stacked container, i3 focuses its
inactive-focused focused child. Sway does the same, but then resets the
focus to whatever was focused previously.
Ref e5992eed16/src/click.c (L207-L219)
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().
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.
Sticky floating containers on an otherwise empty workspace can only be
evacuated if the new output has an active workspace. The noop output may
not have one and in that case we have to move the whole workspace to the
new output.
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.
A "resize shrink width 1px" will cause grow_x to be 0 while grow_width is -1,
incorrectly rejecting the command even though the resize is not a noop. Fix
this by checking width/height instead of x/y.
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.
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.
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.
Prior to this commit, having a layout like T[app1 V[app2]], focusing
app2, and then doing `move left` would result in T[app2 app1]. Now, the
resulting layout is T[app1 app2], which matches i3 behavior.
`container_flatten` updates `container->parent`, meaning that the
existing check would never be true.
i3 shows indicators for the workspace-level pseudo-split, but Sway does
not, as of b977c02. This commit replaces the floating container check
with a call to `container_is_floating`, which has some more robust
checks in place.
Fixes#5699.
We can't arm the timer during cursor creation since the config may not
be ready yet. Instead arm the timer while applying the input
configuration, by this time the configuration has been parsed and we can
arm the hide timer.
Fixes#5686
According to the wayland docs, wayland timers are disarmed on creation.
This leads to the cursor not being hidden if there is no activity after
creation, since the timer is armed on activity, but not at creation.
Arm the timer after creation to ensure the cursor is hidden even if
there is no cursor activity after creation.
Fixes#5684
Reset the event source after unhiding the cursor, to ensure that the
timeout starts after showing the cursor. Also remove the open coded
variant in seat_consider_warp_to_focus().
Fixes#5679
My primary issue was IntelliJ IDEA's code suggestion pop-up not returning focus
to the active editing window.
I have spent some time looking at the changes of @Xyene (#5398) and
@RyanDwyer (#2103). I think my proposed change maintains the status
quo for the most part whilst fixing my focus issue.
I have verified that @Xyene's fix for IntelliJ sub-menus still works.
I have done basic testing which consists of:
- Chrome
- IntelliJ IDEA 2020.2.1
- VSCode
- Alacritty
It seems to hold up. I at least didn't see any obvious errors.

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.
Instead of listening to both transform and scale events, we can listen
to the commit event and use the new wlr_output_event_commit struct to
decide what to do.
This de-duplicates some of the work we were doing twice when an output
was re-configured.
Depends on [1].

If the environment variable is not defined, getenv returns NULL.
Passing a NULL pointer to the "%s" format specifier is undefined
behavior. Even if some implementations output "(null)", an empty
string is nicer.
`!*rgba` tests if the first byte of rgba isn't `'\0'`.
`hex_to_rgba_hex` returns NULL if `parse_color` fails. There's a null
pointer dereference in that case. The intended behavior is `!rgba`.
The pointer `data` is cast to a more strictly aligned pointer type. To
prevent issues, the `data32` buffer is removed and its occurrences are
replaced with an offset from the `data` buffer.
If the mouse/cursor/pointer is near the edge of an output when a "move
position to pointer" command is run, then the floating container will be
constrained to fit inside the bounds of the output as much as possible.
This behavior matches what i3 does in this scenario. I also think it is
a better user experience.
Relates to #4906
The logic for the bounds check follows the implementation in i3: 7330778223/src/floating.c (L536)
Usually it should be enough to simply not grant a client's
minimize request, however some applications (Steam, fullscreen
games in Wine) don't wait for the compositor and minimize anyway,
getting them stuck in an unrecoverable state.
Restoring them immediately lead to heavy flickering when unfocused
on my test application (Earth Defense Force 5 via Steam), so it's
preferable to grant their request without actually minimizing and
then restoring them once they are in focus again.
On warping to a cursor hint, update the pointer position we track as
well, so that on the next pointer rebase we don't send an unexpected
synthetic motion event to clients.
Fixes#5405.
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.

it by skipping handling of the drag icon if it is null.

xdg-shell doesn't allow clients to set the title to NULL, so we

If moving e.g. `T[app app]` into a new workspace with `workspace_layout
tabbed`, then post-move the tree in that workspace will be `T[T[app
app]]`. This still happens with horizontal or vertical workspace layout,
but is less visible since those containers have no decorations.
Fixes#5426.
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
the drag target not being focused when the drag ends. This leads to
unexpected focus behavior, especially for the keyboard which requires
toggling focus away and back to set.
We can only fix the focus once the grabs are released, so refocus the
seat when the wlr_drag destroy event is received.
Closes: https://github.com/swaywm/sway/issues/5116
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
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.
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.
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.
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.
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
as opposed to microseconds. It also considers the value of `tv_sec`, so
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.
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.
This commit moves tool tip event generation into seatops. In doing so,
some corner cases where we'd erroneously (but likely harmlessly)
generate both tablet and pointer events simultaneously are eliminated.
The centering logic needs to take borders, titlebars and CSDs into
account. Instead of using the main surface geometry, use the container
and view geometry, which account for this.
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.
This is necessary because some applications (e.g. Jetbrains IDEs)
represent their multi-level menus as unmanaged surfaces, and when
closing a submenu, the main menu should get input focus.
Closes#5347.
This fixes bugs where a floating container would take input way past its
borders when its parent was fullscreen, since the call to
`tiling_container_at` in input/cursor.c's `node_at_coords` did not check
bounds.
This emits frame events for the seat_cmd_cursor subcommands. The
wl_pointer frame event are required to notify clients when to process
the events. It will now be emitted after cursor movement, button press,
button release, and axis events.
This is a tiny cleanup commit that renames `simulated_tool_tip_down` to
`simulating_pointer_from_tool_tip`, making it match
`simulating_pointer_from_touch`.
This is a better name since it makes it clear that it's the *pointer*
that's being simulated, not the tool tip.
After swaywm/wlroots#2023, #4996 inverted configuration transformations.
For consistency, we should undo (double-apply) the inversion when
communicating via IPC.
Closes#5356.
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.
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 — 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.
Keyboard group keyboards should not call sway_keyboard_configure. They
do not have an input config and they derive their state from the
keyboards within the group.
For some reason, I got sway_keyboard_configure and
seat_configure_keyboard mixed up and thought seat_reset_device called
the latter.
Calling sway_keyboard_configure with a keyboard group's keyboard is not
supported and can cause issues. If any clients are listening to the ipc
input event, a sigsegv will occur due to not every property - such as
identifier - being wired up for keyboard group keyboard's.
This also adds an assertion to sway_keyboard_configure to ensure that
this does not occur in the future and any instances are quickly caught.
If the keyboard that triggers the reload binding is using the default
keymap, default repeat delay, and default repeat rate, the associated
keyboard group is never being destroyed on reload. This was causing the
keyboard group's keyboard not to get disarmed and result in a
use-after-free in handle_keyboard_repeat.
If the keyboard was not using the defaults for all three settings, then
it's associated keyboard would get destroyed during the reset - which
did disarm the keyboard group's keyboard. In this case, the
use-after-free would not occur.
This adds a block to input_manager_reset_all_inputs that resets the
keyboard for all keyboard groups in all seats, which will disarm them.
Since the inputs are all being reset anyway, which will reset all
individual keyboards, it is not necessary to be selective on which ones
get reset.
Add a separate per-view shortcuts_inhibitor command that can be used
with criteria to override the per-seat defaults. This allows to e.g.
disable shortcuts inhibiting globally but enable it for specific,
known-good virtualization and remote desktop software or, alternatively,
to blacklist that one slightly broken piece of software that just
doesn't seem to get it right but insists on trying.
Add a flag to sway_view and handling logic in the input manager that
respects that flag if configured but falls back to per-seat config
otherwise. Add the actual command but with just enable and disable
subcommands since there's no value in duplicating the per-seat
activate/deactivate/toggle logic here. Split the inhibitor retrieval
helper in two so we can use the backend half in the command to retrieve
inhibitors for a specific surface and not just the currently focused
one. Extend the manual page with documentation of the command and
references to its per-seat sibling and usefulness with criteria.

This is a small cleanup commit for removing `sway_tablet` parameters
from functions that already accept `sway_tablet_tool`, since the tablet
reference can be accessed through `tool->tablet`.
This commit renames `motion` and `axis` handlers to `pointer_motion` and
`pointer_axis`, respectively, to disambiguate them from their tablet
(and future touch) handlers. `button` is left as-is, as it is generic
across input devices.
This commit moves tablet motion logic into a seatop handler.
As a side-effect of seatop implementations being able to receive
tablet motion events, fixes#5232.
This commit refactors `cursor_rebase` into `cursor_update_image`, and
moves sending pointer events to the two existing call sites. This will
enable this code to be reused for tablets.
Refs #5232
Currently, clients receive wl_data_device::leave events only when the
pointer enters another surface, which leads to issues, such as #5220.
This happens because wlr_seat_pointer_notify_enter() is called when
handling motion events only for non-NULL surfaces.
Fixes#5220
This is a criteria you can use to select windows since commit
484cc189e9 ("Add shell criteria token"), but there's no way to query
it for an existing window. This exposes its value in the output of
`swaymsg -t get_tree`.
`handle_tablet_tool_set_cursor` was copied from input/cursor.c's
`handle_request_set_cursor`, but the focused surface check was not
adjusted appropriately.

Previously in 3de1a39, it "worked by accident" in my testing since the
display being used in `map_to_output` was initialized first (the map
would not be applied because the display hadn't actually come online
yet), and was followed by a second display (at which point the map would
get applied for the first display).

Fixes#4819.
This commit ensures that `seat_set_focus` is called to transfer focus
when a window is selected via a pen. Previously, it would race with
`node_at_coords`, and only properly transfer focus if its returned
`surface` was NULL.
Some input rules, like `map_to_output`, are dependent on a specific
screen being present. This currently does not work for hotplugged
outputs, or outputs that are processed after the input device is
initially probed.
This commit fixes both cases, by reconfiguring inputs on each output
addition.
Fixes#5231.
This commit refactors `cursor_handle_activity` to also take the idle
source, so that it can be reused for tablet and touch activity.
Previously, the timeouts would be tracked, but the cursor would never be
un-hidden for anything but pointers.
Fixes#5169.
If we started holding the tool tip down on a surface that accepts tablet
v2, we should notify that surface if it gets released over a surface
that doesn't support v2.
Since GTK supports tablet v2, this fixes the common case of starting a
drag over a GTK surface (e.g. scrollbar) and releasing it outside (e.g.
over the gaps between sway containers, or in a terminal).
Refs #5230.
See issue #5228. Currently, WL_OUTPUT_SUBPIXEL_NONE is ignored and
CAIRO_ANTIALIAS_SUBPIXEL is still set. This commit checks if subpixel is

[PR261](https://github.com/emersion/mako/pull/261)
Instead of handling presses and releases on empty workspaces as setting
focus to the workspace, handle releases by notifying the seat of a
pointer action. This way DnDs are correctly released if the button is
released over an empty workspace. This is achieved by removing the early
return and letting the handle_button() call seat_pointer_notify_button()
at the very end.

This color, both in i3 and as described in sway(5), defaults to #888888.
However, the actual default also has an alpha of 88 instead of FF,
meaning it ends up significantly darker than intended.
With these changes, sway will respect positive exclusive zones of layer
surfaces anchored to one or three sides.
This matches the protocol, which states that a positive exclusive zone
should be respected, "if the surface is anchored to one edge or an
edge and both perpendicular edges". If the surfaces is "anchored to
only two perpendicular edges (a corner), anchored to only two
parallel edges or anchored to all edges a positive value will be
treated the same as zero".
This allows e.g. triggering one command while a key is held, then
triggering another to undo the change performed by it afterwards. One
use case for this is triggering push-to-talk functionality for VoIP
tools without granting them full access to all input events.
Fixes#3151
Before the default was "smart". This means a visible app could steal focus

For the 'workspace <name> output <output>' command, output_location must
