Stop trying to maintain a per-file _POSIX_C_SOURCE. Instead,
require POSIX.1-2008 globally. A lot of core source files depend
on that already.
Some care must be taken on a few select files where we need a bit
more than POSIX. Some files need XSI extensions (_XOPEN_SOURCE) and
some files need BSD extensions (_DEFAULT_SOURCE). In both cases,
these feature test macros imply _POSIX_C_SOURCE. Make sure to not
define both these macros and _POSIX_C_SOURCE explicitly to avoid
POSIX requirement conflicts (e.g. _POSIX_C_SOURCE says POSIX.1-2001
but _XOPEN_SOURCE says POSIX.1-2008).
Additionally, there is one special case in render/vulkan/vulkan.c.
That file needs major()/minor(), and these are system-specific.
On FreeBSD, _POSIX_C_SOURCE hides system-specific symbols so we need
to make sure it's not defined for this file. On Linux, we can
explicitly include <sys/sysmacros.h> and ensure that apart from
symbols defined there the file only uses POSIX toys.

Leave it up to the compositor to decide what to do when a backend
becomes unavailable.

This makes wlroots build in C23 mode.
C23 is more strict and rejects implicit conversions from bool to a
pointer.

Under X11, ConfigureNotify means that the window has already been resized.
Sending ConfigureRequest with the received size is not only useless, but also
can confuse the window manager, which will probably reply with the current
(i.e. *old*) size causing a configure loop.

Many files used to require wlr_matrix but no longer do.

We don't need the whole wl_display here anymore. The wl_event_loop
is enough.

Up until now, frame/present events were only triggered when the
user submitted a buffer. Change the wlr_output API so that these
events are triggered when any commit is applied on an enabled
output.

This slightly improves type safety.
The culprits were found with:
git grep -E '\([a-z0-9_ ]+ \*\)\W?[a-z]'

Removes duplication across all the backends to finally apply the mode
to the output.

This changes the semantics of wlr_output_state. Instead of having
fields with uninitialized memory when missing from the committed
bitflag, all fields are always initialized (and maybe NULL/empty),
just like we do in wlr_surface_state. This reduces the chances of
footguns when reading a field, and removes the need to check for
the committed bitfield everywhere.
A new wlr_output_state_init() function takes care of initializing
the Pixman region.

We lock the buffer there, so we need to initialize the n_busy
count to 1 as well.

We sometimes used HAS_, sometimes polluted the LIBINPUT_ namespace,
etc.

Pixman 0.42.0 has constified APIs for pixman_region32_t. We no longer
need the casts.
|
|
The output names must be globally unique per the Wayland spec, even
if the compositor creates multiple backends of the same kind.
|
|
These are unused.
|
|
All we can do to influence adaptive sync on the X11 backend is set the
_VARIABLE_REFRESH window property like mesa automatically does. We don't
have any control beyond that, so we set the state to enabled on creating
the output and never allow changing it (just like the Wayland backend).
|
|
Previously, adaptive sync was just a hint and wouldn't make any
atomic commit fail if the backend didn't support it. The main reason
is wlr_output_test wasn't supported at the time.
Now that we have a way for compositors to test whether a change can
work, let's remove the exception for adaptive sync and convert it to
a regular output state field.
|
|
|
|
This union is unnecessary since the recent input device refactor and can
now be replaced by wlr_*_from_input_device() functions.
|
|
Groundwork for the following commits. The goal is to allow users
to specify their own wlr_output_state instead of wlr_output.pending.

Fixes: be86145322e6 ("output: turn make/model/serial into char *")
|
|
This allows the make/model/serial to be NULL when unset, and allows
them to be longer than the hardcoded array length.
This is a breaking change: compositors need to handle the new NULL
case, and we stop setting make/model to useless "headless" or
"wayland" strings.

The destroy callback in wlr_touch_impl has been removed. The function
`wlr_touch_finish` has been introduced to clean up the resources owned by a
wlr_touch.
`wlr_input_device_destroy` no longer destroys the wlr_touch, attempting to
destroy a wlr_touch will result in a no-op.
The field `name` has been added to the wlr_touch_impl to be able to identify
a given wlr_touch device.
|

The destroy callback in wlr_pointer_impl has been removed. The function
`wlr_pointer_finish` has been introduced to clean up the resources owned by a
wlr_pointer.
`wlr_input_device_destroy` no longer destroys the wlr_pointer, attempting to
destroy a wlr_pointer will result in a no-op.
The field `name` has been added to the wlr_pointer_impl to be able to identify
a given wlr_pointer device.

The destroy member in wlr_keyboard_impl has been removed. The function
`wlr_keyboard_finish` has been introduce to clean up the resources owned by a
wlr_keyboard.
`wlr_input_device_destroy` no longer destroys the wlr_keyboard, attempting to
destroy a wlr_keyboard will result in a no-op.
The field `name` has been added to the wlr_keyboard_impl to be able to identify
a given wlr_keyboard device.

wlr_touch now owns its wlr_input_device. It will be initialized when the
tablet tool is initialized, and finished when the touch is destroyed.
|
|
wlr_pointer owns its wlr_input_device. It will be initialized when the
pointer is initialized, and finished when the pointer is destroyed.
|
|
wlr_keyboard owns its base wlr_input_device. It will be initialized when the
keyboard is initialized, and finished when the keyboard is destroyed.

vendor and product id are set when needed by the libinput backend
