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.
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.
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.

Instead of calling wlr_xdg_surface_for_each_popup and then
wlr_surface_for_each_surface, use the new for_each_popup_surface helper
introduced in [1] that does it in one go.

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.
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.
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.)
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.
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.

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.

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 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.
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.

See issue #5228. Currently, WL_OUTPUT_SUBPIXEL_NONE is ignored and
CAIRO_ANTIALIAS_SUBPIXEL is still set. This commit checks if subpixel is
set to none and if so, calls set_antialias with CAIRO_ANTIALIAS_GRAY.
This mirrors the functionality in Mako's
[PR261](https://github.com/emersion/mako/pull/261)
In the case of multiple overlapping floating windows, this commit fixes an issue where the wrong window would be focused in response to a cursor if one of the windows came from a different output (overhanging).
If a subsurface is created for a surface that is associated with a
scratchpad hidden view, do not attempt to send an enter to it. The
subsurface is not on any output and since there is no workspace
associated with the view, attempting to get the output for the NULL
workspace will result in a SIGSEGV.
The output manager config is created when the output is created. It is
updated when the mode, transform, scale, or layout for the output
changes, as well as, when the output is destroyed.
Since the output->enabled property was not being set before calling
apply_output_config, the output event handlers were early returning and
never updating the output manager config when the output state was
committed.
This fixes the issue by setting output->enabled in apply_output_config
below the output disabling section. There are also a few other minor
changes that are required to function.
Additionally, this renames output_enable to output_configure to better
describe the recent changes.
The only output_enable caller is now apply_output_config. Stop calling
apply_output_config from output_enable to simplify the code and avoid
the back-and-forth between these two functions.
output_enable is now the symmetric of output_disable: it just marks the
output as enabled and performs bookkeeping (e.g. creating teh default
workspace). It is called from apply_output_config after the output
commit, so that it can read the current output state and act
accordingly.
This change also allows us to avoid an extraneous wlr_output_commit.

The container_at_tabbed and container_at_stacked container were checking
the bounds along the y-axis, but not the x-axis. This made it possible
to cause a segfault for specific resolution, horizontal gap, and
workspace children lengths. The issue is that child_index was -1 and was
resulting in a buffer underflow. Adding the x-axis bound checks for
early returns should prevent this from happening.
When a container was being made fullscreen and it is on the focused
workspace for a seat, focus was being set to the container. However,
when the container was on a non-focused workspace, the focus stack
wasn't being touched. When assigning a fullscreen container to a
workspace or moving a fullscreen container to a different workspace,
this would make it so the fullscreen container was never added to the
focus stack for the workspace thus preventing access to the workspace.
This adds the container to the top of the focus stack, behind the
container on the focused workspace.
If a view is mapped to a workspace using an assign, the pid should still
be removed from the pid mapping list. This prevents child processes from
matching against it and mapping a view to a likely undesired workspace.
When gaps are resized for lack of space the calculation could result in
a gap size of non-integer pixels. This would result in containers
located at non-integer pixels which would be subtly broken.
Because the layout code rounds down the dimensions of the windows
resizing would often be off by one pixel. The width/height fraction
would not exactly reflect the final computed width and so the resize
code would end up calculating things wrong.
To fix this first snap the container size fractions to the pixel grid
and only then do the resize. Also use round() instead of floor() during
layout to avoid a slightly too small width. This applies in two cases:
1. For the container we are actually resizing using floor() might result
in being 1px too small.
2. For the other containers it might result in resizing them down by 1px
and then if the container being resized is the last all those extra
pixels would make the resize too large.
Fixes#4391
Any descendant of a scratchpad container may be fullscreen so checking
to see if the top-level scratchpad container is fullscreen in
root_scratchpad_hide is not sufficient. This iterates through all
descendants of the scratchpad container
Showing a window in the scratchpad can move a visible scratchpad window
from another workspace to the current one. If the scratchpad window was
the last visible container in that workspace, the old workspace should
be destroyed.
Calling wlr_output_manager_v1_set_configuration with an enabled output
and a NULL mode is incorrect if the output doesn't support modes.
When DPMS'ing an output, wlr_output_enable(output, false) is called.
This de-allocates the CRTC and sets wlr_output.current_mode to NULL.
Because we mark DPMS'ed outputs as enabled, we also need to provide a
correct output mode. Add a field to sway_output to hold the current
mode.
Closes: https://github.com/swaywm/wlroots/issues/1867
If the view was mapped as fullscreen or the view was assigned either a
workspace or output, the pid was not being populated since it was
occurring as part of the pid mapping check in select_workspace. This
extracts the pid population and makes it so it is always executed
This copies the width and height fractions from the container to the
container replacing it. Without setting these values, the container
is treated as a new container and throws off the existing sizing. Since
one container is replacing the other, it makes sense for the sizing to
remain the same.
Since each seat has its own focus, do not destroy a workspace until it
is no longer focused by any seat. This prevents seats from being forced
to evacuate the workspace just because another seat switched focus away
from it
Since output names can change in various configurations, including
DisplayPort MST, prefer output identifiers for the output priority.
Users can still use `workspace <ws> output <names-or-ids>`, but any
output that is programmatically added to the list will be added under
the output identifier. If the output name exists in the list (from the
user workspace output configs), then that will be retained instead of
switching to the output identifier for that output.
The documentation for wayland-server.h says:
> Use of this header file is discouraged. Prefer including
> wayland-server-core.h instead, which does not include the server protocol
> header and as such only defines the library PI, excluding the deprecated API
> below.
Replacing wayland-server.h with wayland-server-core.h allows us to drop the
WL_HIDE_DEPRECATED declaration.
This commit si similar to wlroots' ca45f4490ccc ("Remove all wayland-server.h
includes").
When arranging the workspace, prev_x and prev_y should be ignoring the
current gaps otherwise the workspace diff_x and diff_y location deltas
will be off. When the deltas are off, each arrangement of the workspace
would incorrectly move floaters an extra -workspace->current_gaps.left
along the x-axis and an extra -workspace->current_gaps.top along the
y-axis.
Instead of tracking gaps per child apply gaps in two logical places:
1. In tiled containers use the layout code to add the gaps between
windows. This is much simpler and guarantees that the sizing of children
is correct.
2. In the workspace itself apply all the gaps around the edge. Here
we're in the correct position to size inner and outer gaps correctly and
decide on smart gaps in a single location.
Fixes#4296
Instead of using container->width/height as both the input and output
of the layout calculation have container->width_fraction/height_fraction
as the share of the parent this container occupies and calculate the
layout based on that. That way the container arrangement can always be
recalculated even if width/height have been altered by things like
fullscreen.
To do this several parts are reworked:
- The vertical and horizontal arrangement code is ajusted to work with
fractions instead of directly with width/height
- The resize code is then changed to manipulate the fractions when
working on tiled containers.
- Finally the places that manipulated width/height are adjusted to
match. The adjusted parts are container split, swap, and the input
seat code.
It's possible that some parts of the code are now adjusting width and
height only for those to be immediately recalculated. That's harmless
and since non-tiled containers are still sized with width/height
directly it may avoid breaking other corner cases.
Fixes#3547Fixes#4297
If there is more than one new window layout correctly by calculating the
default size of the new windows using the information of how many of
them there are in total.
This helps with issue #3547 but doesn't fix it in all situations. Things
now work correctly if the first layout of new windows happens after
leaving fullscreen. But if for some reason an arrange_container() gets
called while we are fullscreen the windows will still be incorrectly
sized after saved_width/saved_height get used to restore the first
window's size before going fullscreen.
The function used for comparing two output names in the workspace
output priority lists was inverted. This was causing priority to not be
stored correctly resulting in workspaces not always being restored or
moved to the desired outputs
Currently container_replace removes the container from the scratchpad
and re-adds it afterwards. For the split commands this results in the
container being send to the scratchpad, which results in a NULL segfault
if the same container should be shown.
Pass an optional workspace to root_scratchpad_add_container, if the
workspace is passed the window will continue to show on the workspace.
If NULL is passed it is sent to the scratchpad.
This was an issue if no other window except the scratchpad container was
on the workspace.
Fixes#4240
This patch fixes faulty command parsing introduced by
f0f5de9a9e. When that commit allowed
criteria reset on ';' delimeters in commands lists, it failed to account
for its inner ','-parsing loop eating threw the entire rest of the
string.
This patch refactors argsep to use a list of multiple separators, and
(optionally) return the separator that it matched against in this
iteration via a pointer. This allows it to hint at the command parser
which separator was used at the end of the last command, allowing it to
trigger a potential secondary read of the criteria.
Fixes#4239
Subsurfaces need access to the parent get_root_coords impl for positioning in
popups. To do this, we store a reference to the parent view_child where
applicable.
Fixes#4191.
When moving a container to become a direct child of the workspace and
the workspace's layout is tabbed or stacked, wrap it in a container
with the same layout. This allows for the following:
- Run `layout tabbed|stacked` on an empty workspace (or use
`workspace_layout tabbed|stacked` in the config)
- Open some views
- Move one of the views in any direction
- Open another view
- The new container should also be `tabbed`/`stacked`
When setting fullscreen on a hidden scratchpad container, there was a
check to see if there was an existing fullscreen container on the
workspace so it could be fullscreen disabled first. Since the workspace
is NULL, it would cause a SIGSEGV. This adds a NULL check to avoid the
crash.
This also changes the behavior of how fullscreen is handled when adding
a container to the scratchpad or changing visibility of a scratchpad
container to match i3's. The behavior is as follows:
- When adding a container to the scratchpad or hiding a container back
into the scratchpad, there is an implicit fullscreen disable
- When setting fullscreen on a container that is hidden in the
scratchpad, it will be fullscreen when shown (and fullscreen disabled
when hidden as stated above)
- When setting fullscreen global on a container that is hidden in the
scratchpad, it will be shown immediately as fullscreen global. The
container is not moved to a workspace and remains in the
scratchpad. The container will be visible until fullscreen disabled
or killed. Since the container is in the scratchpad, running
`scratchpad show` or `move container to scratchpad` will have no
effect
This also changes `container_replace` to transfer fullscreen and
scratchpad status.
When a tiled window is sent to the scratchpad, we want to use sane
defaults, which is to center it and resize it to the default.
For floating windows, we want to use their existing geometry.
This honors the fullscreen output request for
`xdg_toplevel_set_fullscreen` and `zxdg_toplevel_v6_set_fullscreen`.
If the request was sent before mapping, the fullscreen output request
will be retrieved from the client_pending state for the toplevel. The
output will be passed to `view_map` and if there is a workspace on the
output, the view will be placed on that workspace.
If the request comes in after being mapped, the view will be moved to
the workspace on the output (if there is one) before becoming
fullscreen.
This makes it so there will only be one swaybg instance running
instead of one per output. swaybg's cli has been changed to a xrandr
like interface, where you select an output and then change properties
for that output and then select another output and repeat. This also
makes it so swaybg is only killed and respawned when a background
changes or when reloading.
This fixes a crash in `root_scratchpad_hide` when a layer surface is
focused. Since `seat_get_focus` is NULL when a layer surface is
focused, the call to `node_has_ancestor` was causing a SIGSEGV since it
was attempting to access the parent of NULL. This changes the call to
`seat_get_focus_inactive`, which will return a node even when a layer
surface is focused and is also guaranteed to have something in the
focus stack if a scratchpad container is being hidden (otherwise there
would not be any containers yet).
This matches i3's behavior of setting scratchpad containers to 50% of
the workspace's width and 75% of the workspace's height, bound by the
minimum and maximum floating width/height.
