Followup on 4e4898e90f.
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.

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.

Now output_begin_destroy emits the node::destroy event similar to
workspace_begin_destroy. It currently has no listeners, since they
listen to output::disable or wlr_output::destroy instead.
We use the headless backend to create a special fallback output
used when no other output is connected. However this messes up the
"real" headless output names users have come to expect (e.g.
currently the first headless output will be named "HEADLESS-2"
instead of "HEADLESS-1").
Fix this by setting the output name with [1].

sway-bar(5) says:
> For compatibility with i3, bar mode <mode> [<bar-id>] syntax is
> supported along with the sway only bar <bar-id> mode <mode> syntax.
while the actual behavior is that `bar_cmd_mode` ignores already
selected `config->current_bar` and applies the change to all the
configured bars.
This makes it possible to hint to the renderer and backends how many
bits per channel the buffers that the compositor draws windows onto
should have. Renderers and backends may deviate from this if they
do not support the formats with higher bit depth.
Proprietary drivers require --unsupported-gpu to be allowed, and IPCs
require no option to be passed.
The only way to satisfy both is to run IPCs before checking for
proprietary drivers.
Wayland compositors handle many file descriptors: client
connections, DMA-BUFs, sync_files, wl_data_device pipes, and so
on. Bump the limit to the max.

If the focused container is floating by itself, create a new container
in tiling mode as a sibling of the inactive focused container instead of
creating it as a sibling of everything that is in tiling mode in that
workspace. This is the i3 behavior.
seat_get_focus_inactive_floating and seat_get_focus_inactive_tiling do
not always return a view, so get the previously focused view from the
container with seat_get_focus_inactive_view. This is the i3 behavior.
If the destroyed xwayland view is in transaction, it won't
be destroyed immediately. wlr_xwayland_surface then becomes
dangling pointer.

Nvidia has historically been a bad actor in the open-source graphics
ecosystem because they required a special EGLStreams code-path
instead of exposing the de-facto standard GBM API. However, with
their upcoming release they now support GBM as well.
This is a push in the right direction for Nvidia, so there's no
reason we should be more hostile to them than to any other proprietary
driver. Let's remove the --my-next-gpu-wont-be-nvidia flag, and advise
users to use --unsupported-gpu now.
Note, proprietary Nvidia drivers are still unsupported by the Sway
project (just like all other proprietary drivers).

Commit 152a559e replaced the view pointer in the inhibitor struct with a
pointer to the wlr_inhibitor for application inhibitors. But this was not
changed in the sway_idle_inhibit_v1_application_inhibitor_for_view function.
This caused a bug in the sway tree view where the application inhibitor is
always "none".

This commit makes sure the extents are kept up-to-date, fixes not
damaging the surface if its layer shell-specific state didn't change,
and adds a check if the layer shell-specific state didn't change but the
surface got mapped/unmapped, which could affect keyboard focus.
Prior to 62d90a8e, titlebar's font height (and other related values)
would change any time any titlebar's content changed, so these values
were recalculated each time any titlebar's content changed (or a new
titlebar was created).
However, since the above was merge, these values no longer change so
often and we only need to recalculate them when the configured font
changes (and stop calling `config_update_font_height` each time
titlebars are rendered).
This commit removes all the unecessary calls to this function and avoids
all those unecessary calculations. Whenever the font strays from the
default value, the `font` command is called, and it calls
`config_update_font_height`, which is enough to keep the value always up
to date.
I've also added a default value to the `font_baseline` config, since
otherwise that's zero for setups that don't explicitly specify a font.
This prevents sway from extending the desktop to i.e. VR headsets, and makes
them available for DRM leasing.
Non-desktop wlr_outputs will be offered through the wlr_drm_lease_v1_manager
interface for client to lease.
If the surface the pointer started to interact with is destroyed we also
want the seatop_down to end. In case a drag is initiated we receive a
call to handle_end.
This solves an issue where layer-shell items would not receive a button
release event when the pointer left them while being pressed. The
default seatop changes focus immediately while seatop_down defers any
focus changes until the pointer is released or seatop_down is destroyed.
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.

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.
