The problem is that parse_movement_amount is being passed an array of strings of length 0, and it still tries to read the first string in that array, which is garbage and leads to a segfault. The length check on move.c, Line 864 does not ensure that the array passed to parse_movement_amount on line 879 is long enough, because with inputs like 50 px it can be that argc is 2 on line 864, but the first call to parse_movement_amount can consume both of the strings in the command array.

* build: bump wlroots dependency to 0.16.0

* swaymsg: replace if with switch in pretty_print

* swaymsg: add GET_TREE pretty-printing

* swaybar: fix errno handling in status_handle_readable

If getline fails once, it was not reset before the next getline
call. errno is only overwritten by getline on error.

* Add cairo_image_surface_create error handling

cairo_image_surface_create can fail, e.g. when running out of
memory or when the size is too big. Avoid crashing in this case.

Closes: swaywm/sway#6531

* build: bump version to 1.8-dev

Historically we've been sticking with the last release number in
the master branch. However that's a bit confusing, people can't
easily figure out whether they're using a release or a work-in-progress
snapshot. Only the commit hash appended to the version number may
help, but that's not very explicit and disappears when using a
tarball.

We could bump the version in master to the next release number.
However during the RC cycle there would be a downgrade from 1.8 to
1.8-rc1. Also it would be hard to tell the difference between a
stable release and an old snapshot.

This patch introduces a new pre-release identifier, "dev". It's
alphabetically before "rc" so it should be correctly sorted by
semver comparisons. "dev" is upgraded to "rc" (and then to stable)
when doing a release. The master branch always uses a "dev"
version, only release branches use "rc" or stable versions.

* [IPC] Add repeat delay/rate info to keyboard

Closes #6735

wlroots already has the info in the struct so let's access it and print it out.

* input/seat: unset has_focus when focus_stack becomes empty

We currently track the focus of a seat in two ways: we use a list called
focus_stack to track the order in which nodes have been focused, with
the first node representing what's currently focused, and we use a
variable called has_focus to indicate whether anything has focus--i.e.
whether we should actually treat that first node as focused at any given
time.

In a number of places, we treat has_focus as implying that a focused
node exists. If it's true, we attempt to dereference the return value of
seat_get_focus(), our helper function for getting the first node in
focus_list, with no further checks. But this isn't quite correct with
the current implementation of seat_get_focus(): not only does it return
NULL when has_focus is false, it also returns NULL when focus_stack
contains no items.

In most cases, focus_stack never becomes empty and so this doesn't
matter at all. Since focus_stack stores a history of focused nodes, we
rarely remove nodes from it. The exception to this is when a node itself
goes away. In that case, we call seat_node_destroy() to remove it from
focus_stack and free it. But we don't unset has_focus if we've removed
the final node! This lets us get into a state where has_focus is true
but seat_get_focus() returns NULL, leading to a segfault when we try to
dereference it.

Fix the issue both by updating has_focus in seat_node_destroy() and by
adding an assertion in seat_get_focus() that ensures focus_stack and
has_focus are in sync, which will make it easier to track down similar
issues in the future.

Fixes #6395.

[1] There's some discussion in #1585 from when this was implemented
about whether has_focus is actually necessary; it's possible we could
remove it entirely, but for the moment this is the architecture we have.

* swaybar: fix tray_padding vs min-height re: scale

Co-authored-by: xdavidwu <[email protected]>

* swaybar: fix tray item icon scaling, positioning

* container: Fix crash when view unmaps + maps quickly

Followup on 4e4898e.

If a view quickly maps and unmaps repeatedly, there will be multiple
destroyed containers with same view in a single transaction. Each of
these containers will then try to destroy this view, resulting in use
after free.
The container should only destroy the view if the view still belongs
to the container.

Simple reproducer: couple XMapWindow + XUnmapWindow in a loop followed
by XDestroyWindow.

See #6605

* commands/move: Fix crash when pos_y is omitted

Fixes #6737

* Destroy sub-surfaces with parent layer-shell surface

* meson: check: false on run_command

Future meson releases will change the default and warns when the
implicit default is used, breaking builds.

Explicitly set check: false to maintain behavior and silence warnings.

* Print deprecation notice when running SUID

SUID privilege drop is needed for the "builtin"-backend of libseat,
which copied our old "direct" backend behavior for the sake of
compatibility and ease of transition.

libseat now has a better alternative in the form of seatd-launch. It
uses the normal seatd daemon and libseat backend and takes care of SUID
for us.

Add a soft deprecation warning to highlight our future intent of
removing this code. The deprecation cycle is needed to avoid surprises
when sway no longer drops privileges.

* xdg-shell: use toplevel geometry to adjust the popup box

`popup_unconstrain` uses view coordinates to init the output box for
popups. However wlroots expects the box to be set in a toplevel surface
coordinate system, which is not always equal to view. The difference
between those is a window geometry set via xdg-shell.

GTK4 reserves some space for client-side decoration and thus has a
window with top left corner not matching to (0, 0) of a surface. The box
calculated without taking that into account was slightly shifted
compared to the actual output and allowed to position part of the popup
off screen.

* build: fix building with basu

02b412a introduced the use of list for sdbus deps, however
it was assuming that all packages which were in a list has a version
higher than 239. That is true for libsystemd and libelogind, since they
use the same versions, however basu is using version numbers which are
way lower than what libsystemd/libelogind are using, so basu only build
is failing.

* Upgrade for wlroots surface refactoring

See [1] for details.

* commands/focus: drop trailing whitespace

* input/cursor: count pointer gestures as idle activity

Fixes swaywm/sway#6765.

* input/cursor: treat swipe begin as idle activity too

Accidentally overlooked in fd53f80.

* treat fullscreen windows as 'tiled' for commands/focus

* transaction: destroying nodes aren't hidden

Commit 37d7bc6 ("transaction: Only wait for ack from visible
views") introduced a check which uses view_is_visible() to check if a view
is still visible on the screen. However view_is_visible() will early
return in case the node is in the destroying state. This is incorrect
for transactions, since a destroying view which is visible will trigger
configure events for other clients. This bug was visible when repeatedly
opening and closing two views side by side, since we ignore the
destroying node we get a frame where the still open view is shown with
the old configure values and the rest is the desktop background. The
next frame is than correct again.

Fix this by considering destroying views as visible, we correctly wait
for them and send the configure events to other views in time, fixing
the background flicker.

Fixes #6473

* build: execute wlroots subproject before finding deps

wlroots often requires dependencies more recent than Sway's.
Executing the wlroots subproject first will give Meson a chance to
find these newer dependencies, possibly via subprojects.

The subproject will override the "wlroots" dependency when executed,
so we don't need to use get_variable anymore.

* tray: do not render passive items

https://www.freedesktop.org/wiki/Specifications/StatusNotifierItem/StatusNotifierItem/#org.freedesktop.statusnotifieritem.status

* cmd/swap: error on swapping a container with itself

* input/cursor: pass through pointer hold gestures

This just follows swaywm/wlroots#3047, so `wl_pointer_gestures_v1`
clients can be notified of these events.

* swaynag: remove buffer destruction condition

An address of a variable can never be NULL, so checking it doesn't make
sense; and `destroy_buffer()` can operate on already destroyed buffers
anyway.

Fixes #6780

* Use bools for CLI flags

* xwayland: listen to `request_activate` event

When REAPER submenu is closed `XCB_CLIENT_MESSAGE` with type
`NET_ACTIVE_WINDOW` is sent to set focus to parent menu.

* xdg-shell: use wlr_xdg_popup in sway_xdg_popup

Improved type safety.

* Fix snprintf compiler warning

* Remove all sprintf calls

Replace them with snprintf, which ensures buffer overflows won't
happen.

* sway/commands: add missing wlr_keyboard interface include in xkb_switch_layout

* sway/input: use wlr_input_device from input device base

* Remove some erroneous apostrophes in comments

* Don't enter seatop_move_floating when fullscreen

Currently, a floating window that's been fullscreened can send us
xdg_toplevel::move, and we'll enter seatop_move_floating, which lets us
drag the surface around while it's fullscreen. We don't want
this--fullscreen surfaces should always be aligned to the screen--so add
the same check that seatop_default already does when entering this mode.

Tested with Weston's weston-fullscreen demo, which sends a move request
if you click anywhere on its surface.

* swaynag: die on all allocation failures

* sway/input: don't pass possibly invalid modifiers pointer

active_keyboard may be NULL, in which case an invalid pointer could be
passed to wlr_input_method_keyboard_grab_v2_send_modifiers. This
procedure call is unnecessary since wlroots commit 372a52ec "input
method: send modifiers in set_keyboard", so the call can simply be
removed.

Fixes #6836.

* sway/input: destroy sway_switch properly

Fix: #6861
Added seat_device_destroy function to seat_device_destroy function.

* commands/focus: fix segfault when no container is already focused.

Fixes #6690.

* Remove WLR_SWITCH_STATE_TOGGLE usage

* Replace pcre with pcre2

Closes: swaywm/sway#6838

* swaybar: remove swaybar_output.input_region

No need to keep the region around, we can immediately destroy it
after the wl_surface.set_input_region request.

* swaybar: set opaque region

When the background color is fully opaque, set the surface's opaque
region to the whole surface.

* Updating criteria checking with PCRE2

* swaynag: allocate button_details with details

They are used together, so it doesn't make sense to allocate them
separately.

* swaynag: statically allocate button_close, and move declaration

Every swaynag has a close button, so it doesn't make sense to
allocate it dynamically. The declaration is moved later to when
it is actually needed.

* swaynag: remove unnecessary zero of swaynag struct

Global variables are initialized to 0.

* swaynag: remove redundant status variables in main

Instead, we just use `status` for all failures.

* remove unnecessary strlen call

* sway/input/cursor: take device mm size from wlr_tablet

* sway/input/seat: take output name from specialized input device

* sway/input: follow up wlroots input device events renaming

* sway/input: fix bad position of wlr_drag

* sway/input: wlr_seat_keyboard() now takes wlr_keyboard

* bash-completion: localize variables

* sway/main: move constants off the stack

This makes stack traces from gdb slightly easier to read.

* Fix farsi label

* Avoid format-truncation warning

The existing code gives this error when compiled with GCC 12:

../sway/server.c: In function ‘server_init’:
../sway/server.c:217:75: error: ‘%d’ directive output may be truncated writing between 1 and 11 bytes into a region of size 8 [-Werror=format-truncation=]

Because i is never negative, this is a false positive, but it is easy to
change i to unsigned to silence the error.

* Shuffle variables to satisfy -Werror=restrict

This also fixes an invalid strlen invocation on uninitialized memory.

* layer_shell: keep output non-NULL wherever possible

Our layer shell implementation assigns every layer surface to an output
on creation. It tracks this output using the output field on the
underlying wlr_layer_surface_v1 structure. As such, much of the existing
code assumes that output is always non-NULL and omits NULL checks
accordingly.

However, there are currently two cases where we destroy a
sway_layer_surface and output is NULL. The first is when we can't find
an output to assign the surface to and destroy it immediately after
creation. The second is when we destroy a surface in response to its
output getting destroyed, as we set output to NULL in
handle_output_destroy() before we call wlr_layer_surface_v1_destroy(),
which is what calls the appropriate unmap and destroy callbacks.

The former case doesn't cause any problems, since we haven't even
allocated a sway_layer_surface at that point or registered any
callbacks. The latter case, however, currently triggers a crash (#6120)
if a popup is visible, since our popup_handle_unmap() implementation
can't handle a NULL output.

To fix this issue, keep output set until right before we free the
sway_layer_surface. All we need to do is remove some of the cleanup
logic from handle_output_destroy(), since as of commit c9060bc
("layer-shell: replace close() with destroy()") that same logic is
guaranteed to be happen later when wlroots calls handle_destroy() as
part of wlr_layer_surface_v1_destroy().

This lets us remove some NULL checks from other unmap/destroy callbacks,
which is nice. We also don't need to check that the wlr_output points to
a valid sway_output anymore, since we unset that pointer after disabling
the output as of commit a0bbe67 ("Address emersions comments on
output re-enabling") Just to be safe, I've added assertions that the
wlr_output is non-NULL wherever we use it.

Fixes #6120.

strncpy is useless here, is dangerous because it doesn't guarantee
that the string is NUL-terminated and causes the following warning:

Fixes swaywm/sway#7001

* realtime: request SCHED_RR using CAP_SYS_NICE

Try to gain SCHED_RR (round-robin) realtime scheduling privileges before
starting the server. This requires CAP_SYS_NICE on Linux systems.
We additionally register a pthread_atfork callback which resets the
scheduling class back to SCHED_OTHER (the Linux system default).

Due to CAP_SYS_NICE, setting RLIMIT_RTPRIO has no effect on the process
as documented within man 7 sched (from Linux):

  Privileged (CAP_SYS_NICE) threads ignore the RLIMIT_RTPRIO limit;
  as with older kernels, they can make arbitrary changes to
  scheduling policy and priority. See getrlimit(2) for further
  information on RLIMIT_RTPRIO

Note that this requires the sway distribution packagers to set the
CAP_SYS_NICE capability on the sway binary.

* ipc: remove chatty debug log messages

These aren't particularly useful, and clobber the debug logs.

* Refuse to start when SUID is detected

This ensures that those surprised by the deprecation of SUID operation
receive an error rather than accidentally having sway run as root.

This detection will be removed in a future release.

* swaynag: move close_button up to fix SIGSEGV

When swaynag_parse_options encounters '--dismiss-button' (or its
shorthand '-s'), it sets the text of the first button in the
swaynag.buttons list, which is expected to exist and to be the dismiss
button, to the one passed by the user.

Commit 4780afb ("swaynag: statically
allocate button_close, and move declaration") moved the list
initialization to after swaynag_parse_options is called which made that
code fail.

For example, the command 'swaynag --dismiss-button Dismiss' crashes and
'swaynag --message Message --button Yes "" --dismiss-button Dismiss'
shows the wrong buttons.

Move it back to before swaynag_parse_options is called.

* config/output: use wlr_output_commit_state

This makes the code more robust because we don't potentially leave
bad state in wlr_output.pending behind anymore. This also fixes a
bug.

Closes: swaywm/sway#7043
References: https://gitlab.freedesktop.org/wlroots/wlroots/-/merge_requests/3610

* Allocate enough space for `cmd_results->error`

* Remove access to wlr_input_device union

References: https://gitlab.freedesktop.org/wlroots/wlroots/-/merge_requests/3626
Closes: swaywm/sway#7077

* Rename dpms output command to power

The "dpms" command refers to VESA Display Power Management
Signaling, a deprecated standard. It's superseded by VESA DPM.

Instead of tying out command name to a particular standard, use the
neutral term "power".

* Strip quotes in bindsym --input-device=...

If the input device is quoted, which is common when using variables in the
config file, those quotes must be ignored here, or the input device will be
ignored.

Fixes #7029.

* Avoid unecessary string copy

* Reject font values that are invalid for pango

Use pango to parse font configuration early, and reject the command as
invalid if the value is invalid for pango. Since we're already parsing
the font into a `PangoFontDescription`, keep that instance around and
avoid re-parsing the font each time we render text.

Fixes: swaywm/sway#6805

* Reuse parsed PangoFontDescription

Avoids parsing the configured font each time text is rendered.

* ipc: add "power" to output reply

* config.in: switch to `output power`

* Remove internal references to DPMS

While at it, use an int for the config field, just like we do for
all other fields.

* fix: remove redundant empty statement in main.c

This semi-colon looks like a typo. Luckily, it has no effect on the code as it's treated as an empty statement leading the switch case.

Really straightforward nitpick change, was just something I was confused by when reading over the code.

* input: chase delta_discrete semantics change

* swaymsg: fix floating_nodes being ignored

Fix floating_nodes being ignored in pretty_print_tree.

* ipc: make get_deco_rect check config->hide_lone_tab

Without this, the `IPC_GET_TREE` ipc call would return false information
about the container's `deco_rect` and `rect` properties if
`hide_edge_borders --i3` was in effect.

* grimshot: fix tilde expansion within quotes

* Enable single-pixel-buffer-v1

* sway-output.5: improve display of parameter

Since "width" and "height" are separate parameters, show them as such.

* Fix crash in xdg_activation_v1.c

wlr_xdg_surface_from_wlr_surface() can return a NULL pointer, so check for NULL before dereferencing it.

* sway: Add non-desktop-output type

Currently, when encountering a non-desktop display, sway offers the
output for leasing and returns without storing it in a sway specific
output type like `struct sway_output`.  Additionally, running
`swaymsg -t get_outputs` doesn't show non-desktop outputs.

This commit stores the non-desktop outputs into a struct called
`sway_output_non_desktop`, and adds them to a list on `sway_root`

* sway: add non-desktop outputs to json when running `swaymsg -t get_outputs`

* swaymsg: show non-desktop property when pretty printing outputs

* man: Add XWayland information

* ipc: expose mode picture aspect ratio

* swaymsg: show mode picture aspect ratio

* build: simplify protocol paths

No need for arrays here.

* sway/commands/output: Add command for unplugging non-physical outputs

* Improve Japanese translation

* allow pointer_constraints on layer_shell surfaces

* check for NULL

* use seat directly

* Use keyboard_state.focused_surface directly

* input: focus floating container when clicked on border

Fixes #7209.

* input: focus container when scrolling on titlebar

Fixes #6503.

* Fix leaks in criteria_destroy()

* Avoid double free in criteria_destroy()

* Add support for ext-idle-notify-v1

References: https://gitlab.freedesktop.org/wlroots/wlroots/-/merge_requests/3753

* input: tweak focus behavior to allow focusing parent containers

Sway focuses the inactive child when focusing split containers. However,
there is currently no way to focus the parent container itself by mouse.
A user must use the keyboard to do so.

This commit maintains the current behavior, but makes it such that a
second click on the split container titlebar (i.e., after its children
are visible) focuses the split container itself.

* Fix keymap being NULL and segfaulting on dev add

Moved `libinput_config` to the callers of
`sway_input_configure_libinput_device` so that we send the event after
the added event.

* Rework session lock keyboard focus handling

When removing outputs, it is possible to end up in a situation where
none of the session lock client's surfaces have keyboard focus,
resulting in it not receiving keyboard events.  Track the focused
surface and update it as needed on surface destroy.

* Fix focus tracking when session lock is active

Remove the incorrect attempt to block focus changes when an input grab
is present and replace it with the same logic used for layer_shell-based
screen lockers: restore the focus after changing it.

This fixes a use-after-free of seat->workspace if outputs are destroyed
while a screen lock is enabled.

* container_floating_set_default_size: Store workspace size box on the stack

* Support libinput's 1.21 new dwtp option

Support the new dwtp (disable while trackpointing) option introduced in
libinput 1.21, allowing users to control whether the trackpoint (like
those in Thinkpads, but not only) should be disabled while using the
keyboard/touchpad.

See: https://gitlab.freedesktop.org/libinput/libinput/-/issues/731

* tree: support formatting null titles

Any windows that have never had a title set visually behave closer to
that of an empty title, but are unformattable, as the code bails out
early on a NULL title.

* criteria: allow matching on empty (NULL) titles

* criteria: allow matching for NULL string criteria

* ci: install hwdata

* Use wl_signal_emit_mutable()

This function fixes segfaults when emitting a signal potentially
removes arbitrary listeners.

* Use wlr_damage_ring

wlr_output_damage is to be replaced with wlr_damage_ring, so use that.

* lock: fix crash on output destroy

Closes: swaywm/sway#7120

* container_get_siblings: handle NULL workspace

* ci: checkout wlroots 0.16.0

* workspace_create: Don't allow NULL name

(cherry picked from commit 34933bb)

* output: set damage ring bounds to pixel values

Fixes: swaywm/sway#7254
(cherry picked from commit 85005b5)

* Use shm_open instead of mkstemp

shm_open is more reliable because it does not require
a writeable filesystem folder, unlike mkstemp.

(cherry picked from commit e2bc886)

* build: drop wayland-scanner fallback

(cherry picked from commit 366f6ef)

* build: unify server & client protocol generation

No need to make a difference here, let's just generate header
files for both.

(cherry picked from commit 5be5a03)

* build: drop "server" from target name for protocol code

(cherry picked from commit e5475d9)

* build: drop intermediate libraries for protocols

(cherry picked from commit af8a5a8)

* root: move the workspace matching code to its own file

This removes the pid_workspace bits from tree/root before it gets
too interesting.

No functional change.

(cherry picked from commit eb5021e)

* node: prettify node type names

(cherry picked from commit 1c4b94a)

* launcher: track workspaces by node

This removes the need to rename the pid_workspaces when a workspace
is renamed.

It also opens the possibility of tracking other node types. Tracking
containers would allow application to be placed correctly in the
container tree even if the user has moved their focus elsewhere since
it was launched.

(cherry picked from commit 3b49f27)

* launcher: use xdga tokens

This reuses wlroots token tracking for workspace matching. It doesn't
export any xdga tokens for clients yet.

(cherry picked from commit bd66f49)

* launcher: rename pid_workspace to launcher_ctx

Soon we will match views with more than just a pid.

(cherry picked from commit d75c9f9)

* view: associate launch contexts with views

Views now maintain a reference to a launch context which, as a last
resort, is populated at map time with a context associated with its pid.
This opens the possibility of populating it before map via another
source, e.g. xdga-tokens or configuration.

(cherry picked from commit 864b3a9)

* launcher: initialize launcher_ctxs once on startup

(cherry picked from commit 6656850)

* launcher: fudge the interface a bit

We want to create a context before knowing the pid it will match with.

(cherry picked from commit bdeb9f9)

* launcher: export xdga tokens and use them for workspace matching

(cherry picked from commit 30ad4dc)

* launcher: export X startup ids and use them for workspace matching

(cherry picked from commit 28fda4c)

* swaybar: Prioritize hotspot events to bar bindings

This is consistent with i3bar's behaviour, and for example, allows binding a
command to button1, while still being able to click on tray icons or other
zones on the bar's status line which may have their own bindings.

E.g., in Sway, without this commit, this config. makes tray icons unclickable:

    bar {
        # ...
        bindsym button1 exec swaynag -m You_clicked_the_tray._Want_some_help?
    }

But the same configuration in i3 (with i3-nagbar) keeps tray items clickable.

(cherry picked from commit 53f9dbd)

* swaybar: Make hotspots block bar release bindings

The previous commit prioritized hotspots before bar bindings for press events,
which matches i3's behaviour. However, since hotspots don't need to do any
processing on release events, those were not handled, and simply fell through
to `bindsym --release` bar bindings (if any).

This is counter-intuitive, and doesn't match i3's behaviour. Instead in case
a hotspot handles the press event, it should also handle the release event,
doing nothing, but blocking the event from triggering a --release bar binding.

E.g., in Sway, without this commit, this config. shows a text on tray clicks:

    bar {
        # ...
        bindsym --release button1 exec swaynag -m I_got_the_release_event.
    }

But the same configuration in i3 (with i3-nagbar) doesn't show the text.

* build: drop unused wayland-egl dependency

(cherry picked from commit 37e4a3d)

* build: bump version to 1.8-rc1

* Fix build on Debian Stable

(cherry picked from commit dca0bb5)

* build: fix have_xwayland when xcb-icccm is not found

xcb-icccm is required to build Xwayland support.

Backported from commit d41f11e.

* build: bump version to 1.8-rc2

* seat: Avoid sending redundant keymaps on reload

When we reload the config, we reset every input device and re-apply
configuration from the config file. This means that the keyboard keymap
is updated at least once during config reload, more if the config file
contains keyboard configuration.

When they keyboard keymap changes and is updated through wlr_seat, the
keymap ends up sent to every keyboard bound in every client, seemingly
multiple times. On an x230 of mine with a keyboard layout set in the
config file, I see 42 keymap events sent to foot on config reload.

Reduce events from keyboard configurations by skipping all but the
currently active keyboard for the seat, and by clearing the active
keyboard during input manager device reset. After this change, I only
see a single just-in-time keymap event.

Fixes: swaywm/sway#6654

* criteria: be lenient on window_role and instance too

* build: bump version to 1.8-rc3

* commands/move: Warp cursor after moving workspace to another output

This makes sway's behavior consistent with i3 when `mouse_warping` is
set to any value besides `none`.

Fixes #7027.

(cherry picked from commit e3c63bf)

* seat: Set keyboard if seat keyboard is NULL

sway sends wl_keyboard.enter on seat focus change and when a keyboard
active on a seat is configured. If all keyboards are removed and a
keyboard is added back without changing the focused client, no new
notify event would be sent despite having keyboard focus. This could
lead to key events without notify, which is a protocol violation.

As a quick fix, when configuring a keyboard on a seat where no keyboard
is currently active, activate the keyboard so that a focused surface
will receive a notify event.
