f48cf18a16 compositor: Fix harmless potential buffer overflow
We could overflow a local buffer if there were more than ten million
concurrently active displays within the current user's session. This
seems vanishingly unlikely, and harmless, but does at least squash a
compiler warning emitted by gcc 12+.

b3ba1becba libweston: remove fbdev backend
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.

a882794027 compositor: add icc_profile weston.ini option for outputs
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.

81ef6d0ab3 compositor: add weston.ini option use-renderer-shadow
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.

b5265af620 libweston: add color ops cap and bool renderer shadow buffer
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.

32a5acde5b tests: add mechanism to change Weston's behavior when running certain tests
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.

ae69381b6e compositor: avoid setting WAYLAND_DISPLAY=wayland-0
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.

e57d8ae818 drm-backend: add --continue-without-input command line option to DRM-backend
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.

Add flag --continue-without-input to DRM-backend so we can run
these types of tests with no input. Notice that this won't force
the compositor to skip opening a input device if it finds it on
the non-default seat.

8060d826b7 Redefine output rotations
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 function weston_log_ctx_compositor_destroy(), which destroys struct
weston_log_context, takes weston_compositor as argument. We may have a

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.

dd8219b3fb option-parser: Make bools boolean
When option-parser is confronted with a boolean option, have it write a
bool rather than treating the value as a pointer to an int32.

(lib)weston already heavily uses bool types internally, so this has the
nice side effect of eliminating quite a few local variables which only
existed as integer shadows of internal boolean variables.

b35c21f70c compositor: turn weston main() into a lib
This takes everything that was in 'weston' the executable a turns it into
library. A new trivial 'weston' executable is written.

Creating the library will allow future improvements:

- 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
directory, away from the normal libraries in a system. This is one library we
do not intend for others to use.

The library has no stable ABI and is not versioned.

c232f8d934 Unify the include style of shared/ 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.

The "bad" include style was found with:
$ for h in shared/*.h; do git grep -F $(basename $h); done | grep -vF '"shared/'

5c5f0272d9 compositor: Do not trigger invalid destructors when hotunplugging
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.

3957863667 log: remove "%m" from format strings by using strerror(errno)
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.

6e229ca263 weston: add more libinput config options
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.

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.

b9454fde9f weston: keep non-desktop displays turned off by default
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.

3b1c1efe34 main: do not exit in case stdin is a closed stream
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")

5c91bb8d28 compositor: protocol logger
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.

d3630ed489 compositor: offer logs via weston-debug
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.
