Between fork() and exec() in the child process it is only safe to use
async-signal-safe functions. Surprisingly, snprintf() is not such
function. See e.g. https://stackoverflow.com/a/6771799 and how snprintf
is not listed in signal-safety(7) manual.
Therefore we must prepare the fd argument strings before fork(). That is
only possible if we also do not dup() fd in the child process. Hence we
remove the close-on-exec flag instead in the child process which has
copies of the parent's file descriptors. Fortunately fcntl() is safe.
struct fdstr is helping to reduce code clutter a bit.
Additionally, if fork() fails, we now clean up the fds we created.

Between fork() and exec() in the child process it is only safe to use
async-signal-safe functions. weston_log() definitely is not one, it
allocates memory and does whatnot.
weston_log() is also inappropriate for other reasons: the child process
has its own stream buffers and flight-recorder. No-one looks into the
child process' flight recorder, so messages would be lost there. The
logging machinery might also attempt to write into debug streams,
meaning both parent and child could be writing simultaneously.
It seems that the best we can do is to pre-bake an error message and
only write() it out if exec() fails. There is no mention that even
strerror_r() might be safe to call, so we don't.

Doing any kind of memory allocation calls between fork() and exec() in
the child process is prone to deadlocks and explosions. In general, only
async-signal-safe functions are safe there.
Move the config access to the parent process before fork() to avoid

The problem is triggered by configuring a bad path to Xwayland in
weston.ini, which causes exec() to fail. The fork() succeeded though,
which means the weston_process was already on the watch list, and the
watch can be handled, making sigchl_handler() leave the link
uninitialized.
Making sure the link remains removable fixes this.

This adds an option to program basic display color characteristics from
weston.ini. In the future there will be a way to set this information
from EDID, but because EDID is unreliable that will probably not be the
default. An ICC profile will likely override most or all of this. The
main reason to add this option is to be able to characterise HDR
monitors.
An 'output' section can have a key 'color_characteristics' (string)
set to a name. The name refers to any 'color_characteristics' section
with 'name' set to the same string.
The 'name' key of a 'color_characteristics' section cannot contain a
colon ':'. Names with colon in 'output' section key
'color_characteristics' value are reserved for future use, e.g. to
indicate that the metadata is to be taken from EDID instead of a
weston.ini section.

When we launch clients they currently stay in the same session as
weston, and share its controlling terminal. This means hitting ctrl-c
in weston's controlling terminal will send SIGINT to the clients as
well. It also means SIGHUP will be propagated to our launched clients
if weston's controlling terminal is closed.
While generally not harmful, this behaviour is not beneficial, and
is present by default and not by design.
Problems arise when launching weston in a debugger, as a ctrl-c sent to
the debugger will be propagated not only to the debugger, but all the child
processes sharing weston's session. This results in weston-desktop-shell
being killed by the ctrl-c that was intended to stop weston for debugging.
If weston-desktop-shell is killed within 30 second of startup, it will
result weston performing a clean shutdown. This clean shutdown can
make debugging a little too surprising.
Ostensibly, clients launched via weston_client_launch will be wayland
clients that terminate cleanly on their own if weston is killed, so
there should be no need for them to remain in weston's session to
catch ctrl-c from its controlling terminal. Nor should they need a
controlling terminal for their general operation.
Use setsid() to move them to their own session, devoid of controlling
terminal, to make using a debugger a little less confusing in some
cases.

signalfd interacts badly with gdb's signal trapping - when hitting
ctrl-c in a debugger attached to weston, weston will receive the
signal. This results in weston exiting cleanly when the intent
was to use gdb to interfere with its operation.
Trapping SIGINT was introduced in commit 50dc6989 which ensured we
would call wl_display_terminate() on SIGINT or SIGTERM to clean
up our socket.
Killing weston with SIGINT is quite common for several developers,
so it's important to preserve this clean shutdown behaviour, so
we can't naively stop trapping SIGINT entirely.
Instead, use the sigaction() function to trap SIGINT, and have
the SIGINT handler send weston SIGUSR2 (SIGUSR1 is already
used by xwayland). SIGUSR2 can be trapped in the proper wayland
way via wl_event_loop_add_signal(). This way we can properly
break our event loop and clean up on SIGINT, but we can also
have gdb intercept SIGINT.
There are other ways around this, but I'm hoping this one allows
people to continue using ctrl-c to stop weston, and doesn't
require additional project specific gdb knowledge.

We've been trapping SIGQUIT for a "clean shutdown" since commit 3cad436a
However, sources such as:
http://www.gnu.org/software/libc/manual/html_node/Termination-Signals.html
indicate we probably shouldn't be trapping it at all, as the intent of
SIGQUIT is to leave a core file and debug artifacts from the run.
We should perform the minimal amount of clean up to ensure the system isn't
left in an unusable state - but these days that's performed by other
software such as logind.
We can safely stop trapping SIGQUIT entirely.

Fbdev backend was deprecated in the Weston 10.0.0 release with
6338dbd581. Before that, I suggested
already in 2019 to remove it, but it was too soon then. Now it seems the
final voices asking for fbdev to be kept have been satisfied, see the
linked issue.
Fbdev-backend uses a kernel graphics UAPI (fbdev) which is sub-par for a
Wayland compositor: you cannot do GPU accelerated graphics in any
reasonable way, no hotplug support, multi-output support is tedious, and
so on. Most importantly, Linux has deprecated fbdev a long time ago due
to the UAPI fitting modern systems and use cases very poorly, but cannot
get rid of it if any users remain. Let's do here what we can to reduce
fbdev usage.
I am doing color management related additions to libweston which require
adding checks to every backend. One backend less is less churn to write
and review.
Libweston major version has already been bumped to 11, so the next
release will be Weston 11, without fbdev. enum weston_compositor_backend
entries change their numerical values.

This adds "icc_profile" key support in [output] sections for backends
headless, x11, wayland, and drm, and also for remoted and pipewire
outputs FWIW. On the other hand, RDP-backend does not use output
sections from weston.ini, and fbdev-backend does not deserve anything
new (it wouldn't support color management anyway due to no GL-renderer).
This allows one to configure an ICC v2 or v4 file to be used as an
output profile. However, color-lcms does not actually use output
profiles yet, so trying this will fail until support is implemented.
The parent_winsys_profile argument is reserved for using the color
profile from a parent window system where applicable, if nothing else is
set in weston.ini. None of the nested backends provide an output color
profile yet. It is more of a reminder of a missing feature than a
serious implementation.
Note: cms-static Weston plugin uses the exact same weston.ini key for
loading VCGT from ICC profiles. If "color-management" option is set to
false, this new use of "icc_profile" is disabled and the old behavior
with cms-static is kept.

This adds an output section option use-renderer-shadow in weston.ini.
This option is only recognized with headless and DRM backends, because
it requires GL-renderer and does not support resizing outputs.
The option is called use-renderer-shadow because this is what it does
right now. In the future the same setting will be used to turn on more
complex image processing when operational pieces required for color
management land. Once color management is implemented, this option is
expected to be removed. This option allows developer testing of features
to be used to implement color management.
This is a rewrite of "weston.ini: introduce use-shadow-fbo in output
config" by Harish Krupo. The main.c code is structured differently, the
weston.ini option is renamed, and the man page paragraph is moved to
weston.ini.man with different content.

This adds the libweston capability bit for "color operations" which
refers to a renderer's support for operations needed for color
management. GL-renderer will grow the support while Pixman-renderer will
not, which is why the cap is needed.
To make an example use of the cap, this also adds new API:
weston_output_set_renderer_shadow_buffer(). This is a temporary API to
enable future experimental features. The first such feature will be the
renderer internal shadow buffer, the boolean variable for it taken from
Harish Krupo's "weston.ini: introduce use-shadow-fbo in output config".
Obviously this patch does not implement the renderer shadow buffer. No
renderer sets WESTON_CAP_COLOR_OPS yet so trying to enable it will fail.
The documentation here is deliberately vague, because the bits needed
for color management will come in trickling for a long time until we can
call it color management in any sense. Until then, the temporary API
shall remain, perhaps poorly named.

There are some specific cases in which we need Weston to
behave differently when running in the test suite. This
adds a new API to allow the tests to select these behaviors.
For instance, in the DRM backend we plan to add a writeback
connector screenshooter. In case it fails for some
reason, it should fallback to the renderer screenshooter
that all other backends use. But if we add a test to
ensure the correctness of the writeback screenshooter,
we don't want it to fallback to the renderer one, we
want it to fail. With this new API we can choose to
disable the fallback behavior specifically for this test.

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.

In the test suite we may want to run a DRM-backend test on a

Weston's default behavior is to not open if input devices are

open but if no input device is set than the user can not
interact or leave it.

Regardless of the default transform passed in, weston_parse_transform

weston_config for the transform, with the default being 'normal'.
Fix it so we return the passed-in default transform when we have a

declared but invalid, we can remove the line resetting to the default

It was discovered in issue #99 that the implementations of the 90 and 270
degree rotations were actually the inverse of what the Wayland specification
spelled out. This patch fixes the libweston implementation to follow the
specification.
As a result, the behaviour of the the weston.ini transform key also changes. To
force all users to re-think their configuration, the transform key values are
also changed. Since Weston and libweston change their behaviour, the handling
of clients' buffer transform changes too.
All the functions had their 90/270 cases simply swapped, probably due to
confusion of whether WL_OUTPUT_TRANSFORM_* refers to rotating the monitor or
the content.
Hint: a key to understanding weston_matrix_rotate_xy(m, c, s) is that the
rotation matrix is formed as
c -s
s c
that is, it's column-major. This fooled me at first.
Fixing window.c fixes weston-terminal and weston-transformed.
In simple-damage, window_get_transformed_ball() is fixed to follow the proper
transform definitions, but the fix to the viewport path in redraw() is purely
mechanical. The viewport path looks broken to me in the presence of any
transform, but it is not this patch's job to fix it.
Screen-share fix just repeats the general code fix pattern, I did not even try
to understand that bit.

The only reason why we have both weston_compositor_tear_down() and

After commit "weston-log: replace weston_log_ctx_compositor_destroy()

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

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.

This takes everything that was in 'weston' the executable a turns it into
library. A new trivial 'weston' executable is written.

- 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
install_rpath is set so that we can install the library into weston's module

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.

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
include seach paths from the compiler.
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.

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
flip).
When the backend output is finally destroyed, it will trigger a
destruction callback previously added by the compositor, which point to
data belonging to the top-level wet_output object.
In order to avoid access to invalid data when the backend output is
destroyed after the top-level wet_output object, remove the destruction
callback from the corresponding list before freeing the object.

The member disable_planes of weston_output signifies the recording
status of the output, and is incremented and decremented from various
places. This patch provides helper functions to increment and decrement
the counter. These functions can then be used to do processing, before
and after the recording has started or stopped.

The function pixman_blt may return false in case there is no
accelerated blit function available. In this case the remote shared
screen stays black.
This has been observed on Weston compiled for aarch64. In currrent
pixman 0.38.4 there is no accelerated pixman_blt function for
aarch64 available.
Use pixman_image_composite32 instead which is guaranteed to have a
working fallback implementation.
Fixes: #253

avoids unnecessary calculation of damaged regions on resize,
makes sure that the whole screen is considered damaged on
resize and simplifies error handling.

It is quite similar to the remoting plugin. It just exports the frames via
pipewire instead of the builtin GStreamer pipeline.
It implements the same virtual output API. Virtual outputs can be created
by adding 'pipewire-output' sections to weston.ini.
The generated frames can be accessed with any pipewire client. e.g. with
GStreamer:
gst-launch-1.0 pipewiresrc ! video/x-raw,format=BGRx ! ...

Logging should start as early as possible so create the log scope as
early as possible, before subscribing to it.
Open the logfile before creating the 'logger' subscriber, making sure
we're logging to the file properly.
Also migrate `weston_log_set_handler()` to avoid potential calls to
`weston_log` before installing the log handler.

Destroying the compositor after destroying the log scope will not print
out the messages in the tear down/clean-up phase of the compositor, so
add a new tear_down function which allows keeping a valid reference to
the compositor. This way we can destroy the compositor before destroying
the scope and keep the debug messages.
While at it remove the log context destroy part from the clean-up
of the compositor and make it stand on its own.

config-parser.h is a helper API that libweston core must never depend on. Using
it is a compositor frontend decision.
Including it in libweston.h would give the wrong message.

Allow a gstreamer pipeline to be configurable via an weston.ini. It is
necessary that source is appsrc, its name is "src", and sink name is
"sink" in pipeline. Also, remoting plugin ignore port and host
configuration if the gst-pipeline is specified.
This patch enables a user to opt for HDCP per output, by writing into
the output section of weston.ini configuration file. HDCP is always
enabled by default for the outputs.

By default the client communicates its preference with regards to
compression to the server. However, some clients always use
compression, which is not ideal for certain environments (e.g.
low performance embedded devices in a local network with plenty
of bandwidth). Allow to disable compression server-side which will
override the clients request for compression.

WESTON_OPTION_BOOLEAN takes a pointer to an int as an argument, but

This changes it to use a local int instead, and then write that value 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).
While there, fix some minor indentation issue.
