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.
This fixes the following ASAN use-after-free error on a build slightly

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)
free(): double free detected in tcache 2
00:00:00.608 [swaynag/swaynag.c:451] failed to register with the wayland display
Aborted (core dumped)
Minimal reproducer config:
bar {
foo bar
position top
}
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.
