Meson is a build system, currently implemented in Python, with multiple
output backends, including Ninja and Make. The build file syntax is
clean and easy to read unlike autotools. In practise, configuring and
building with Meson and Ninja has been observed to be much faster than
with autotools. Also cross-building support is excellent.
More information at http://mesonbuild.com
Since moving to Meson requires some changes from users in any case, we
took this opportunity to revamp build options. Most of the build options
still exist, some have changed names or more, and a few have been
dropped. The option to choose the Cairo flavour is not implemented since
for the longest time the Cairo image backend has been the only
recommended one.
This Meson build should be fully functional and it installs everything
an all-enabled autotools build does. Installed pkg-config files have
some minor differences that should be insignificant. Building of some
developer documentation that was never installed with autotools is
missing.
It is expected that the autotools build system will be removed soon
after the next Weston release.

In current form SHM buffers pixel format can only be printed as 0 and 1.

Use the pixel format table to parse format names. This makes the parser
recognize almost all DRM format names.
Not all formats are usable, but we rely on the use to fail
appropriately. What we can use depends on the drivers anyway.

There is often a need to print the name of a pixel format. Printing the
raw numeric value is hard to decipher, printing the four ASCII
characters is slightly more human-friendly but still needs a decoder
table. Add a name that can be printed easily.

It's a bit surprising that Weston looks different when launched from the root
of the git repo vs from elsewhere.
But it's also technically a security vulnerability: if I launch it from
a directory like /tmp, it might pick up a weston.ini created by another user,
which could then load modules with arbitrary code. Basically, it's the same
problem as including "." in $PATH.

input panel implementation puts contents of an

on top of all other surfaces. It is not controllable

For toplevel surfaces, the shell will do the same thing. Without this, the
commit does not trigger repaints, because the output mask for the surface
is not set.
Without this the popup is not shown unless something else triggers a
repaint. This is usually not seen because the mouse cursor triggers a
repaint at the same time.

Introduce a helper function to disconnect the client on unhandled
buffer types, and use it in the gl and pixman renderers. The function
is modeled after linux_dmabuf_buffer_send_server_error.
Also print the egl error state in the gl renderer, in case the
unrecognized buffer error happens when querying an egl buffer.

If the view is not mapped, we do not need to update its
properties. We can use ivi_view_is_mapped() function to
check it.
Also we don't need to call weston_view_damage_below()
for weston_views, which were in the scenegraph. Because
we are calling weston_view_unmap for views of unmapped
ivi_views in build_view_list() function
Signed-off-by: Emre Ucan <eucan@de.adit-jv.com>
From Michael Olbrich:
"Both the core in weston_compositor_build_view_list() with view.link
and the ivi-shell in commit_screen_list() with view.layer_link
don't remove the old views from the list.
As a result, all views that are not currently in the list have
old broken links. Destroying such a view tries to remove
the view from these lists and will access the old, invalid pointers."
Therefore, we have to unmap weston_views which are not in current
scenegraph of ivi-shell. I implemented ivi_view_is_mapped() function
to check mappedness of ivi_views. The functions checks:
- the view is on a layer's order list
- the layer is on a screen
- the layer and view's ivi_surface are visible
If ivi_view is not mapped but weston_view is still mapped,
we have to unmap the weston_view with weston_view_unmap() call.

Remoting plugin support streaming image of virtual output on drm-backend
to remote output. By appending remote-output section in weston.ini,
weston loads remoting plugin module and creates virtual outputs via
remoting plugin. The mode, host, and port properties are configurable in
remote-output section.
This plugin send motion jpeg images to client via RTP using gstreamer.
Client can receive by using following pipeline of gst-launch.
gst-launch-1.0 rtpbin name=rtpbin \
udpsrc caps="application/x-rtp,media=(string)video,clock-rate=(int)90000,
encoding-name=JPEG,payload=26" port=[PORTNUMBER] !

rtpbin. ! rtpjpegdepay ! jpegdec ! autovideosink \
udpsrc port=[PORTNUMBER+1] ! rtpbin.recv_rtcp_sink_0 \
rtpbin.send_rtcp_src_0 !
udpsink port=[PORTNUMBER+2] sync=false async=false
where, PORTNUMBER is specified in weston.ini.

Xwayland block SIGUSR1 signal for handling this signal. However, if some
weston plugins creates additional threads before xwayland is loaded,
this signal get delivered these threads and causes weston quit.
Therefore, we should set up SIGUSR1 blocking early so that these threads
can inherit the setting when created.

Not every output will have a backlight control, and even if it does we
may just not be able to find it. Not having backlight control isn't an
error, so don't spam the log with it, as doing so can confuse users into
thinking this is an actual error which is responsible for their real
problems.

Not having swap_buffers_with_damage could cause a performance impact on
some backends, but at least on GBM it causes no issues. It also seems to
confuse users into thinking it's a legitimate error which could explain
session slowness.
Similarly with buffer_age, whilst we do lose a little bit of performance
by not being able to do partial renders, it is not a great deal, and the
user is unlikely to be able to do anything about it in any event.
Remove the warning; we print the full extension list at startup, so we
already have enough information from the logs to easily diagnose any
real errors.
