If there were no outputs in the output layout,
wlr_output_layout_get_box would return the box:
{
.x = INT_MIN,
.y = INT_MIN,
.width = INT_MIN - INT_MAX,
.height = INT_MIN - INT_MAX
}
which results in an integer underflow for both the width and height.
This changes the logic to have the box be all zeroes, since an empty
output layout does not have a width or height and the location of
something without a size is irrelevant so this just uses the origin.
The grab serial can be used to start a pointer grab. A button pressed event
should be used for this purpose.
Thus, we should only save the grab serial if it's the first button pressed
event we send. This commit makes it so the serial is not saved if a button is
released while another button is still pressed.
In case a tool was removed, but not yet destroyed by the client, the
tool_client's tool can be NULL. We have to check that as well in the
set_cursor handler to prevent using inert resources
This commit makes sure surface->mapped is true when the unmapped event is
emitted. This is necessary because listeners can only damage surfaces that are
mapped. This is similar to the fact that the destroy event is emitted before
any destruction is actually made.

There is no point in modesetting an output to a mode that it is already
set to. Modesetting will cause the output to briefly flicker which is
undesirable for a noop. This prevents modesetting any wlr_output,
regardless of the backend, to it's currently set mode.
data-control: separate out a data_offer struct
This is a prerequisite to adding primary selection support.
data-control: separate out data_control_source
This is a prerequisite to adding primary selection support, since that
doesn't use wlr_data_source, but rather wlr_primary_selection_source.

It doesn't make sense to keep popups opened when unmapped. We also need to do
so in wlr_xdg_popup_destroy so that popups are destroyed in the correct order.
This supersedes f24e17259e and
04c9ca4198. These commits were manually removing
wlr_data_source destroy handlers when starting a new drag. This is error-prone.
Instead, this commit destroys the previous source whenever we start a new drag.
Frame events group logically connected pointer events. It makes sense to make
the backend responsible for sending frame events, since once the events are
split (ie. once the frame events are stripped) it's not easy to figure out
which events belongs to which frame again.
This is also how Weston handles frame events.

This makes compositors able to block and/or customize set_selection requests
coming from clients. For instance, it's possible for a compositor to disable
rich selection content (by removing all MIME types except text/plain). This
commit implements the design proposed in [1].
Two new events are added to wlr_seat: request_set_selection and
request_set_primary_selection. Compositors need to listen to these events and
either destroy the source or effectively set the selection.

Fixes a crash in SDL2 applications when using locked pointer.
SDL2 expects a wl_pointer v1 interface and doesn't provide a handler for
the wl_pointer::frame event. This results in a "listener function for
opcode 5 of wl_pointer is NULL" abort in wayland-client.
Tested on Xonotic v0.8.2 with libSDL2 v2.0.9. Xonotic needs to be ran
with "SDL_VIDEODRIVER=wayland xonotic-sdl" for SDL2 to use the wayland
backend.
When there aren't enough CRTCs for all outputs, we try to move a CRTC from a
disabled output to an enabled one. When this happens, the old output's state
wasn't changed, so the compositor thought it was still enabled and rendering.
This commit marks the old output as WLR_DRM_CONN_NEEDS_MODESET and sets its
current mode to NULL.
Occurs on subsequent calls to
relative_pointer_manager_v1_handle_get_relative_pointer()
Steps to reproduce:
- run rootston
- run examples/relative-pointer
- switch to relative pointer more than once
Note: if done fast enough it may take more than two switches to crash.
In particular, modified public creator and destructor function names,
added a display destroy listener, safely extract user data from
resources, send correct time (in usecs) in rootston, etc.
This is a common interface that can be used for all primary selection
protocols, as discussed in [1]. A new function wlr_seat_set_primary_selection
is added to set the primary selection for all protocols.
The seat now owns again the source, and resets the selection to NULL when
destroyed.

This commits completely refactors wlr_gtk_primary_selection. The goal is to
remove gtk-primary-selection state from the seat and better handle inert
resources where it makes sense.
wlr_seat_client.primary_selection_devices has been removed and replaced by
wlr_gtk_primary_selection_device. This allows us to make offers inert when the
current selection is replaced.
wlr_seat_set_primary_selection has been removed because it relied on wlr_seat
instead of wlr_gtk_primary_selection_device_manager. A new function,
wlr_gtk_primary_selection_device_manager_set_selection (candidate for the
longest function name in wlroots) has been added. It doesn't take a serial
anymore as serial checking only makes sense for set_selection requests coming
from Wayland clients (serial checking is now done in the Wayland interface
implementation).
Since wlr_gtk_primary_selection_device_manager is now required to set the
selection, a new function wlr_xwayland_set_gtk_primary_selection_device_manager
(candidate number two for longest function name) has been added.
Devices are now made inert when the seat goes away.
Future work includes removing the last primary selection bits from the seat,
mainly wlr_seat.primary_selection_source and wlr_seat.events.primary_selection,
replacing those with new fields in wlr_gtk_primary_selection_device. Or maybe
we could keep those in the seat and replace them with a re-usable interface
(for future zwp_primary_selection_v1 support). We need to think how we'll sync
these three protocols (GTK, X11 and wayland-protocols).

wlr_subsurface_from_wlr_surface can return NULL if the wl_surface is still
alive and if the wl_subsurface has been destroyed. Make sure we check for NULL.

This commit makes it possible for a single client to have multiple data devices
for the same seat. This fixes issues with Firefox.
This mainly removes wlr_data_source.offer. We make sure we create one data
offer per device. We now make the offer inert when the source is destroyed.
Fixes the second half of https://github.com/swaywm/wlroots/issues/1041
The read format is dependent on the output, so we first need to make it
current. This fixes a race condition in wlr-screencopy-v1 where a dmabuf
client would cause EGL_NO_SURFACE to be bound at the time when
screencopy needs to query for the preferred format, causing GL errors.
When a client was creating multiple data devices for the same seat, we were
only creating one resource. This is a protocol error.
Instead, create one offer per data device.
This commit also makes offers inert when their source is destroyed.
Fixes part of https://github.com/swaywm/wlroots/issues/1041

ie. don't destroy surface->toplevel on xdg_toplevel destroy. Instead do this on
xdg_surface destroy.
This allows compositors to add toplevel listeners when the surface appears and
remove them when the surface is destroyed.
We were assuming GL_BGRA_EXT was always supported.
We now check that it's supported for rendering. We fail if it isn't because
this format is specified as "always supported" by the Wayland protocol.
We also check if it's supported for reading pixels. A new preferred_read_format
function returns the preferred format that can be used to read pixels. This is
used by the screencopy protocol.
There was a missing copy_drm_surface_mgpu call in drm_connector_schedule_frame
so we asked for a pageflip with an unknown BO, resulting in ENOENT.
Additionally, this commit makes schedule_frame return a bool indicating
failures. This allows schedule_frame_handle_idle_timer to only set
frame_pending to true if a frame has been successfully scheduled. Thus, if a
pageflip fails, rendering won't be blocked forever anymore.
In case a pageflip is already pending, true is returned because a frame has
already been scheduled and will be sent sometime soon.
shm_open is a POSIX function creating an in-memory file. Using it simplifies
the code and removes the dependency on XDG_RUNTIME_DIR. The only downside is
that we need to generate a random name for the shm file.
Prior to this commit, setting up a zero timeout resulted in a timer that never
expires, which isn't particularly useful.
This commit allows setting up timers that expire immediately, which is useful
to immediately enter idle state.
wlr_cursor: make sure the output doesn't have a cursor before
creating a new one
wlr_output_layout: don't emit the "add" event when the output is
already in the layout
The prevoius implementation would always raise an error in the following sequence:
-> enter
-> leave
<- enable
The text-input type is not equipped to manage the validity of clents' requests, which should be handled in the compositor, as rootston does.
If a client uses an older version of the dmabuf protocol, use the
`formats` event instead of `modifiers` (since that didn't exist in older
versions).
With a bit of necessary guessing, support dmabuf importing even when
EGL_EXT_image_dma_buf_import_modifiers isn't present instead of
failing up front.
