Log subscriber API is not type-safe. File and flight recorder
subscribers are created with functions that return
weston_log_subscriber objects. But there's a problem: to destroy
these objects you have to call the right function for each type
of subscriber, and a user calling the wrong destroy function
wouldn't get a warning.
Merge functions that destroy different types of subscribers, making
the log subscriber API type-safe.

The cms-static, desktop-shell, hmi-controller, ivi-shell, and screen-share
modules use symbols from libexec_weston, e.g.:
$ ldd /usr/lib/x86_64-linux-gnu/weston/desktop-shell.so | grep "not found"
libexec_weston.so.0 => not found
Loading these modules from weston happens to work because the weston executable
itself links against libexec_weston, and has an rpath set. Still, these modules
depend on a library in a non-standard location. Adding an rpath could help
static checkers to make sure all shared objects' dependencies are present.

The only reason why we have both weston_compositor_tear_down() and
weston_compositor_destroy() is that the only we had to destroy
the log context was keeping weston_compositor alive and calling
weston_log_ctx_compositor_destroy().
After commit "weston-log: replace weston_log_ctx_compositor_destroy()
by weston_log_ctx_destroy()", it's not necessary to keep a zombie
weston_compositor just to be able to call
weston_log_ctx_compositor_destroy().
Fold weston_compositor_tear_down() into weston_compositor_destroy(),
as this split is useless now.

The function weston_log_ctx_compositor_destroy(), which destroys struct
weston_log_context, takes weston_compositor as argument. We may have a
weston_log_context unlinked from a weston_compositor and currently there
is no way to destroy it.
Add function weston_log_ctx_destroy(), what makes the destruction of
weston_log_context independent of weston_compositor.
With this change, one could destroy a weston_compositor and keep the
related weston_log_context (since now weston_log_context can be destroyed
without the need of a weston_compositor). But if weston_compositor gets
destroyed it's also necessary to destroy weston_log_context::global,
as the debug protocol depends on the compositor. So a listener has been
added to the destroy signal of weston_compositor.

Define the void pointer as pixman_region32_t instead of using it

Void pointers are used by generic API's so each user can define

This introduces a new convention of checking through the compositor destroy
listener if the plugin is already initialized. If the plugin is already
initialized, then the plugin entry function succeeds as a no-op. This makes it
safe to load the same plugin multiple times in a running compositor.
Currently module loading functions return failure if a plugin is already
loaded, but that will change in the future. Therefore we need this other method
of ensuring we do not double-initialize a plugin which would lead to list
corruptions the very least.
All plugins are converted to use the new helper, except:
- those that do not have a destroy listener already, and
- hmi-controller which does the same open-coded as the common code pattern
did not fit there.
Plugins should always have a compositor destroy listener registered since they
very least allocate a struct to hold their data. Hence omissions are
highlighted in code.
Backends do not need this because weston_compositor_load_backend() already
protects against double-init. GL-renderer does not export a standard module
init function so cannot be initialized the usual way and therefore is not
vulnerable to double-init.

- we can link weston plugins against the library, meaning that they no longer
need unresolved symbols to be allowed during linking
- tests do not have to fork() and exec() 'weston', they can just link to the
library and call wet_main() after setting things up; this will help with
using a debugger

We have two kinds of libweston users: internal and external. Weston, the
frontend, counts as an external user, and should not have access to libweston
private headers. The shell plugins are external users as well, because we
intend people to be able to write them. Renderers, backends, and some plugins
are internal users who will need access to private headers.
Create two different Meson dependency objects, one for each kind.
This makes it less likely to accidentally use a private header.
Screen-share is a Weston plugin and therefore counts as an external user, but
it needs the backend API to deliver input. Until we are comfortable exposing
public API for that purpose, let it use internal headers.

Define common_inc which includes both public_inc and the project root directory.
The project root directory will allow access to config.h and all the shared/

Replacing all custom '.', '..', '../..', '../shared' etc. include paths with
common_inc reduces clutter in the target definitions and enforces the common
#include directive style, as e.g. including shared/ headers without the

Unfortunately this does not prevent one from using private libweston headers

When all shared/ headers are included in the same way, we can drop unnecessary

This include style was chosen because it is prevalent in the code base. Doing
anything different would have been a bigger patch.
This also means that we need to keep the project root directory in the include
search path, which means that one could accidentally include private headers
with
#include "libweston/dbus.h"
or even
#include <libweston/dbus.h>
IMO such problem is smaller than the churn caused by any of the alternatives,
and we should be able to catch those in review. We might even be able to catch
those with grep in CI if necessary.

$ for h in shared/*.h; do git grep -F $(basename $h); done | grep -vF '"shared/'

When hotunplugging a display, the compositor will tear the top-level
wet_output object down, freeing its memory.
However, destruction of the backend output might be delayed in certain
situations (e.g. destroying DRM output while in the middle of a page

When the backend output is finally destroyed, it will trigger a
destruction callback previously added by the compositor, which point to

The printf() format specifier "%m" is a glibc extension to print
the string returned by strerror(errno). While supported by other
libraries (e.g. uClibc and musl), it is not widely portable.
In Weston code the format string is often passed to a logging
function that calls other syscalls before the conversion of "%m"
takes place. If one of such syscall modifies the value in errno,
the conversion of "%m" will incorrectly report the error string
corresponding to the new value of errno.
Remove all the occurrences of the specifier "%m" in Weston code
by using directly the string returned by strerror(errno).

This is so that, for instance, people using weston as their main Wayland
compositor can invert the sense of two finger scrolling or change
pointer acceleration using weston.ini, rather than having to edit C
code.
All of the options that libinput itself exposes through its API are now
exposed in weston.ini. The new options are called `tap-and-drag`,
`tap-and-drag-lock`, `disable-while-typing`, `middle-emulation`,
`left-handed`, `rotation`, `accel-profile`, `accel-speed`,
`scroll-method`, `natural-scroll`, and `scroll-button`. I have
successfully tested everything except for `rotation`, out of a lack of
hardware support.
weston now depends directly on libevdev for turning button name strings into
kernel input codes. This was needed for the `scroll-button` config
option. (weston already depends indirectly on libevdev through
libinput, so I figured people would be OK with this.) As a practical
matter for debian-style packagers, weston now has a build dependency on
libevdev-dev.
Right now, the code applies the same options to all attached devices
that a given option is relevant for. There are plans for multiple
[libinput] sections, each with different device filters, for users who
need more control here.

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.

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.recv_rtp_sink_0 \
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.

We are currently formatting 32-bit signed integers into 8 byte buffers,
which are too small, causing the compiler to complain. Update the buffer
size to the minimum required value of 12 bytes: 1 for the sign, 10 for
the number, and 1 for the null byte terminator.

Keep non-desktop heads representing e.g. head mounted displays turned off by
default. When using the DRM backend they can still be enabled by setting an
explicit [output] mode (or "mode=preferred") in weston.ini.

Weston should not exit if stdin is a closed stream. This allows
to launch with a closed stdin:
# weston <&-
This fixes screen sharing using weston: Weston closes the stdin
before forking itself to execute the screen sharing instance of
weston. Before this patch screen sharing failed with:
Screen share failed: No wl_shm found
unknown child process exited
Fixes: f0d39b2243 ("weston: Set CLOEXEC on stdin")

This is better than running Weston with WAYLAND_DEBUG=server:
- It is enabled on demand, no unnecessary flooding and no need to
restart the compositor if debug was enabled.
- It prints client pointers so that messages with different clients can
be seen apart.

This registers a new weston-debug scope "log" through which one can get
live log output interspersed with possible other debugging prints. This
is implemented by passing the format and varargs received in our usual
logging entrypoints through to the debug scope as well.
Anywhere where the varargs set is used twice (once for vfprintf, another
for the debug scope), we copy the va_list in order to avoid reusing it,
which leads to memory safety issues.

Add a new boolean output section key "force-on". When set to true, the
output will be enabled regardless of connector status. This is the
opposite of the mode=off setting.
Forcing connectors on is useful in special circumstances: avoid output
configuration changes due to hotplug e.g. with KVM switches, or hardware
with unreliable connector status readout for example.
