Found mutable global variables with
$ grep -P '^static (?!const).*[=;]' -- compositor libweston shared
Mutable global or static variables make it harder to run several
compositor instances in the same process. That is what the test suite
would probably need to do to test wayland-backend.
This one variable does not need to be mutable.

If weston.ini is not setting background-image path,
then desktop-shell sets ${DATDIR}/weston/pattern.png
as background. However in this case width and height
is set to 1 during background config and is being
scaled to avoid allocation of buffer.
This behavior is not right. Along with background-image
path, we should also check if background-color is set.
If background color is set, then only scale 1x1 buffer.
This would allow to set pattern.png as default wallpaper
of weston correctly, if background-color is also not set
in weston.ini file.

96bef0517e "drm-backend: add support for
writeback connectors" started using DRM_MODE_CONNECTOR_WRITEBACK and
DRM_CLIENT_CAP_WRITEBACK_CONNECTORS. These were introduced in libdrm
2.4.95.
According to
https://gitlab.freedesktop.org/wayland/weston/-/merge_requests/311
Ubunut Xenial is the only mentioned distribution that does not provide a
libdrm new enough. I think that is fine to drop now, 2016 was a good
while ago.
Libdrm 2.4.95 also introduced DRM_CLIENT_CAP_ASPECT_RATIO,
DRM_MODE_PICTURE_ASPECT_64_27, DRM_MODE_PICTURE_ASPECT_256_135.
The fallback definitions for the above are dropped.

Properly release the seat on RDP disconnect. Using current master
branch which is commit d93c0f7059 ("backend-rdp: fix memory leak")
I was not able to reproduce the crash on reconnect as mentioned in the
current comment. Using Weston with rdp-backend directly as well as
using the screen-share plug-in allowed to reconnect just fine. Hence
release the Weston seat properly using weston_seat_release and free
the seat structure. This also avoids mouse pointers displayed for
every RDP connection.

Recognize writeback connectors and add 'struct drm_writeback'

Instead of directly creating heads for the connectors in functions
drm_backend_create_heads() and drm_backend_update_connectors(),
add drm_backend_add_connector() that will handle this.
This split makes the code look better and will also make our lives

The function drm_connector_assign_connector_info() should
not be calling functions to handle drm_head, as connectors
and heads are not the same thing after patch "drm-backend:
move connector data from struct drm_head to struct drm_connector".
Move drm_head specific calls to drm_head_update_info(). This
is more in line with the hierarchy of the objects and also
allow us to drop drm_head pointer from drm_connector.

Instead of calling drmModeGetConnector() in drm_head_create()
and drm_head_update_info(), it is better to call it in
drm_backend_create_heads() and drm_backend_update_heads().
Then we can pass the drmModeConnector object as parameter.
This does not change the behavior of the code, but help us
to avoid unnecessarily calling drmModeGetConnector().
Besides that, in the future we will have support for writeback
connectors. And so drm_backend_create_heads() will be reworked
to also populate a list of writeback connectors. To make this
work, we are going to need to know if a connector is of the
writeback type or not, to know if we should call drm_head_create()
or drm_writeback_create(). We can only tell the type of connector
if we have the drmModeConnector object.

Instead of calling drmModeObjectGetProperties() each time that we need

This is the first step in order to add support for writeback
connector in Weston. We don't want writeback connectors data
to be stored in 'struct drm_head' objects, as these objects are
used to output content and we should not use writeback connectors
for this purpose.
The writeback connectors will be stored in a new 'struct
drm_writeback', but the connector data is common between
'struct drm_head' and 'struct drm_writeback'.
So move connector data from 'struct drm_head' to 'struct
drm_connector'. This helps to avoid code duplication and makes
the code clearer.

In commit c1e89ba2 "compositor-drm: move connector fields into
drm_head" the function drm_head_assign_connector_info() was
introduced. By that time it was being used only at drm_head
creation, and not to handle connector changes.
In d2e6242e "compositor-drm: create heads for all connectors"
it started to be used also to handle connector changes. In
this scenario we replace old connector props with newer data.
Before doing this, free the old connector data to avoid memory
leak.
Note that as drm_property_info_free() is safe to be called on
a zero-initialized struct, we can call it even in the case where
the head is being created and there are no props yet.

This commit alters the way that Weston picks a Wayland display socket
name. Instead of using wl_display_add_socket_auto to look for the first
available name in wayland-0, wayland-1, .... to wayland-32, the code now
checks names wayland-1, wayland-2, .... up to wayland-32.
This change is a workaround for a suboptimal behavior of
libwayland-client. If a client program calls wl_display_connect(NULL) and
the WAYLAND_DISPLAY environment variable is not set, then the program will
by default try to connect to 'wayland-0'. This is a problem when a
computer has a running Wayland compositor but is being accessed in some
other fashion, such as through an X session on a different virtual
terminal, over ssh, etc. Client programs launched through those means may
attempt to connect to an unrelated compositor. Changing libwayland
behavior to remove the default would also work, but a) libraries have
stronger backward compatibility expectations b) that would likely break
more people's setups than just changing Weston would.

Now that we have a CRTC list in the DRM-backend, we can
iterate through it and look for the CRTCs that do not have
assigned outputs in order to find unused CRTCS.
So we can drop unused_crtcs from struct drm_backend and also
drop the functions drm_backend_update_unused_outputs() and
wl_array_remove_uint32().

There are no 'struct drm_output' for CRTCs that are not active.
Also, CRTC data lives in 'struct drm_output'. This is causing
us some trouble, as the DRM-backend needs to program those
unnactive CRTCs to be off.
If the DRM-backend had the reference for every CRTC (being
active or not), it would make certain functions (e.g.
drm_pending_state_apply_atomic()) more simple and efficient.
Move CRTC data from 'struct drm_output' to 'struct drm_crtc',
as this is the first step to allow the DRM-backend to have
references for every CRTC.
Also, add list of CRTCs to DRM-backend object. Now the
DRM-backend is responsible for allocating/deallocating the CRTC
objects. The outputs will only reference, init and fini the CRTCs
in this list.

Currently doesn't exist a standard way to write a weston.ini inside a test.
Here, two new functions `weston_ini_setup` and `cfgln` are introduced to
help the test writer to write a weston.ini file and load it to the test.
And `internal-screenshot-test` is converted to use the new method of write
a weston.ini. This conversion serves as example and initial API test.
The tester needs to call `weston_test_harness_execute_as_client` or
`weston_test_harness_execute_as_plugin` in the same way as before.
The `weston_ini_setup` will fill the setup->config_file with the
correct path to the weston.ini file.
The main design goal is to avoid pre-made or build-made weston.ini(s)
and keep the test as self-contained as possible.

After some changes in the exposay layout, the outer padding makes
no sense anymore. It was used to avoid the panel to get overlapped
by the exposay surfaces and to keep distance from the borders

Currently, the exposay is centralized and the panel cannot get

We've been using an inner border of fixed size (80px), but this

Also, it creates a lot of unnecessary space, making the exposay

be 90% of its original size, avoiding the crashes and making it
