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
For i3 compatibility, allow the indicator and child_border colors values
to be optional. The indicator will fallback to sane defaults and
child_border will fallback to the background color for the class.
This is the third commit in a series of commits to refactor color
handling in sway. This removes add_color from commands.c. It was only
being used by bar_cmd_colors. This also changes the functions to use
parse_color which is used to validate rgb(a) colors throughout the code
base and is also what i3bar is using to parse the colors after they are
passed over ipc. After parsing the color and ensuring it is valid, the
rgba hex string is then generated using snprintf. This refactor also
ensures that all the colors for the command are valid before applying
any of them.
This is the second in a series of commits to refactor the color handling
in sway. This removes the duplicated color parsing code in
sway/commands/client.c. Additionally, this combines the parsing of
colors to float arrays with that in sway/config.c and introduces a
color_to_rgba function in commom/util.c.
As an added bonus, this also makes it so non of the colors in a border
color class will be changed unless all of the colors specified are
valid. This ensures that an invalid command does not get partially
applied.
This is the first in a series of commits to refactor the color handling
in sway. This changes parse_color to return whether it was success and
no longer uses 0xFFFFFFFF as the fallback color. This also verifies that
the string actually contains a valid hexadecimal number along with
the length checks.
In the process of altering the calls to parse_color, I also took the
opportunity to heavily refactor swaybar's ipc_parse_colors function.
This allowed for several lines of duplicated code to be removed.
When arranging layer-shell layers, verify that the currently focused
layer, if any, for each seat is still keyboard interactive. If the layer
is no longer keyboard interactive and there is not a keyboard
interactive overlay or top layer to change the focus to, refocus the
focus inactive node for the seat.
When many surfaces are created, sway can run out of file descriptors,
making wl_event_loop_add_timer (which creates a timerfd) fail and
return NULL. This patch posts a "no memory" error when that is the case,
and only removes the timer if it was created.
(Why "no memory"? It is not easy to distinguish between failures due to
running out of memory and failures due to running out of file
descriptors. Also, using the newer `wl_client_post_implementation_error`
function would lead to an increased version requirement for the
libwayland-server dependency.)
This removes `seat <seat> keyboard_grouping keymap` and replaces it with
`seat <seat> keyboard_grouping smart`. The smart keyboard grouping will
group based on both the keymap and repeat info. The reasoning for this
is that deciding what the repeat info should be for a group is either
arbitrary or non-deterministic when multiple keyboards in the group have
repeat info configured (unless somehow exposed to the user in a
reproducible uniquely identifiable fashion).
When clicking on the titlebar of a floating container (or descendant of
a floating container), the top-level floating container was being
focused and then allowing you to move the top-level floating container.
This made it so you couldn't switch to a different tab/stack within the
floating container. With this patch, the focus inactive view for the
container that the titlebar is associated with is focused, then the
traversal to the top-level floating container is performed to use with
the move floating operation.
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
When an input becomes available, the input type config for that device
type will be merged underneath the input identifier config, provided
they both exist. If an input type config gets added or modified at a
later point, then those changes get merged onto the input identifier
configs for that type. However there was a missing case of the input
identifier config being added after the device is already available and
the input type config existing. This makes it so that the first time an
input identifier config gets stored, there will be a check to see if it
matched any of the available devices. If it does, then there will be a
search for the associated input type config, which will be merged
underneath the input identifier config if found.
This defers the destruction of wlr_keyboard_groups until idle. This is
to prevent the keyboard group's keyboard from being destroyed in the
middle of handling a keyboard event. This would occur when changing the
keymap of the last keyboard in a group with a keyboard binding. The
prevents crashing when attempting to update the xkb state of the
keyboard group's keyboard. The sway_keyboard_group is still immediately
destroyed so that the group is no longer used
This adds two missing calls to wl_list_remove to remove the key and
modifier listeners for the keyboard group's keyboard when destroying
the keyboard group. This fixes some crashes when changing the keymap of
the last keyboard in a group with a keyboard binding.
This adds seat configuration options which can be used to configure what
events affect the idle behavior of sway.
An example use-case is mobile devices: you would remove touch from the
list of idle_wake events. This allows the phone to stay on while you're
actively using it, but doesn't wake from idle on touch events while it's
sleeping in your pocket.
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.
If a layer is focused by any seat, it needs to be unfocused on unmap. If
the unmap was due to an output being disabled, there would not be a
sway_output and unmap would do an early return. This results in a
use-after-free if the layer was focused by any seat prior to being
unmapped. This change just moves the refocusing code above the early
returns.
Some wayland clients (mostly GTK3 apps) like eog or evince support
gestures like pinch-to-zoom. These gestures are given to clients
via the pointer_gestures_v1 protocol. This is already supported in
wlroots, so we just need to hook up the events here in sway.
Fixes#4724
Transparency gets reset when the script is terminated.
Added command line option to set transparency strength without changing
the script.
Added support for multiple displays.
When making the reload validation improvements, I forgot that input type
configs are stored in a separate list. This makes it so input type
configs are correctly applied on reload.
Repaint scheduling delays output render and frame done events from
output frame events, and block idle frame events from being scheduled in
between output frame done and output render in this period of time.
If a surface is committed after its frame done event, but before output
render, idle frame requests will be blocked, and the surface relies on
the upcoming render to schedule a frame.
If when the repaint timer expires, output render is deemed unnecessary,
no frame will be scheduled. This can lead to surfaces never having their
frame callbacks fire.
To fix this, we store that a surface has requested a frame in
surface_needs_frame. When the repaint expires, if no render is deemed
necessary, we check this flag and schedule an idle frame.
Fixes#4768
max_render_time can be set on output, view, or both. However, if only
applied to the output, send_frame_done_iterator would erroneously send
frame_done immediately, ignoring the output max_render_time. As
damage_handle_frame processed max_render_time correctly, idle frames
would be blocked in anticipation of the delay that was meant to happen.
Without the delay, frame events would be dispatched during the idle
frame block, and some clients would never receive the frame done events
they had requested, at least not until something else actively drove
another render.
Respecting both view and output max_render_time in
send_frame_done_iterator ensures that the frame events are always
correctly delayed.
Fixes#4756
If a sway keyboard is being destroyed, then the keyboard is being
removed from a seat. If the associated wlr_keyboard is the currently
set keyboard for the wlr_seat, then we need to reset the wlr_seat's
keyboard to NULL so it doesn't reference an invalid device for the seat.
The next configured keyboard from the seat or the next keyboard from
that seat that has an event will then become the seat keyboard.
Similarly, this needs to be done for a wlr_keyboard_group's keyboard
when the wlr_keyboard_group is being destroyed.
For the validation pass of reloading, there is no need to touch swaybg,
swaynag, inputs, outputs, or seats. This drastically improves the speed
of a reload by skipping over the expensive I/O configuration and
handling of wayland clients. As long as the syntax is valid, the
CMD_FAILURE's can be relayed during the actual reload.
In sway_keyboard_destroy, only remove the keyboard from a keyboard
group, if it is part of a keyboard group. If the keyboard is not part of
a keyboard group, then there is nothing to remove it from
When being created, non first seats would get through the list of devices
without the list being first initialised -> segfault.
Issue introduced with ab0248a545Fixes#4750: Crash when reloading Sway with multiple seats configured
A wlr_keyboard_group allows for multiple keyboard devices to be
combined into one logical keyboard. This is useful for keyboards that
are split into multiple input devices despite appearing as one physical
keyboard in the user's mind.
This adds support for wlr_keyboard_groups to sway. There are two
keyboard groupings currently supported, which can be set on a per-seat
basis. The first keyboard grouping is none, which disables all grouping
and provides no functional change. The second is keymap, which groups
the keyboard devices in the seat by their keymap. With this grouping,
the effective layout and repeat info is also synced across keyboard
devices in the seat. Device specific bindings will still be executed as
normal, but everything else related to key and modifier events will be
handled by the keyboard group's keyboard.
