The output capture protocol is also provided by the kiosk shell and the

Signed-off-by: Michael Tretter <m.tretter@pengutronix.de>
The functionality of this screenshooting helper client is kept exactly
the same as before: if you have multiple outputs, some transformed, some
scale, in any layout, this will create a "multi-image" where the
framebuffer (the physical image) of each output is pasted into a row of
images in the order the outputs were advertised thrugh wl_registry.
Output transform or scale are not accounted for. If you have a monitor
rotated sideways, the screenshot will have the image of that monitor
reverse-sideways.
Otherwise the client is almost completely re-written, so trying to read
the diff is not that useful.
The old screenshooting protocol is replaced with the new
weston-output-capture protocol. This makes it unnecessary to listen for
wl_output information (since we do not handle output transform or scale
anyway).
The buffer sizes and formats are dictated by the compositor, which also
means we cannot hardcode the format. Hence, use Pixman for the blitting,
in case it needs to do format conversion. It is good to get rid of
hand-crafted pixel data manipulation code too.
For that reason we also need a pixel format database to convert between
DRM fourcc, wl_shm and Pixman codes. We link to libweston to borrow its
database instead of inventing another partial copy of it. It's weird to
use compositor library private API in a client, but better than the
alternative.
The original code had no tear-down code at all. Now, if everything
succeeds, the program ends with no unfreed memory according to ASan. If
something fails, it still YOLO's it (doesn't free stuff). That's how far
my pedantry carried.
I also did not bother taking output transform or scale into account,
since the old code did not either. It would be nice to create a seamless
image of the desktop with shots rotated and scaled to align, in the max
scale over all outputs. Meh.

Similar to changes in simple-dmabuf-egl, this perform a x-axis

The motivations for this are:
- Y_INVERT is not used by most real-world clients.
weston-simple-dmabuf-egl and weston-simple-dmabuf-v4l are one only
known users. Thus this creates a special case just for these demo
clients.
- Some compositors (wlroots) have dropped support for DMA-BUF flags,
so the client no longer runs there.
- Dropping the flag allows compositors to use a KMS hardware plane to
display the buffer.
It keeps the same axis orientation we had in place where we had the
y-invert flag enabled by default, by doing a reflection about x-axis.

Recently I learnt that fprintf() is not async-signal-safe. Maybe it also
attempts to allocate memory sometimes. Hence, using it when we
presumably are out of memory is wishful thinking.
Therefore replace that with async-signal-safe code. If you have to check
pointers from traditional signal handlers, now you could do that too!
While doing this, we also lose the string formatting for line number. I
would argue that printing file and line number is not that useful, if
the system really is out of memory. If not out of memory, a core dump
would give us much more detailed information about what went wrong.
clients/window.c had some calls to fail_on_null() and these are simply
replaced. They were used for checking that creating new wl_proxy by
issuing a protocol request worked, and IIRC that only fails on
out-of-memory, so the same rationale applies here.

Setting the opaque region correctly is common source of error for

This is especially true once buffer_scale and buffer_transform come

in logical coordinates.
As faulty opaque regions don't have a visual impact in these cases

This is particulary important when attempting to start simple-egl either

commit a buffer with the original dimensions, and later on to resize to

This fixes an issue when running simple-dmabuf-feedback:
"wl_display@1: error 1: invalid arguments for wl_surface@3.attach".
As we are not using create_immed request from zwp_linux_dmabuf_v1, we
can't start to use a dma-buf buffer before we process compositor's event
telling us that the creation succeeded.
This was causing problems in the following scenario:
1. buffer is marked to be recreated (because of dma-buf feedback);
2. in buffer_release() event, we destroy the buffer and recreate it;
3. after we recreate it, roundtrip is not called, as we don't want to
block during the drawing loop;
4. buffer status is not being properly tracked, so we are trying to
use a buffer before receiving the event from the compositor telling
us that the creation succeeded.
To fix this, this patch improves buffer status tracking. Now we only
pick a buffer in the drawing loop when it is available. Also, if we have
no buffers available we perform a roundtrip and try again, as we may
have recreated all of them but still didn't have the chance to process
compositor's events telling us that creation succeeded.

Since commit 992ee045f1 we create a new surface when we update the cursor
image. This broke animated cursors by discarding any existing frame
callback used for timing, and moving the setup for frame callbacks to
after the commit on the pointer surface.
To fix this we need another surface commit for the frame callbacks, but
this alone is not enough to fix the regression, as a lingering kludge
intended to fix problems when reusing the pointer surface is no longer
working as intended.
Since we no longer re-use the same surface, we can delete the old surface
on pointer exit, along with any callbacks set on it. Then a frame callback
will be recreated naturally. This lets us remove the now broken kludge
from the past and restore animated cursor functionality.

When trying to get Weston to run on a new system I was building up bit
by bit, I encountered a problem: when I started weston-terminal, it
would close a split second later. This turned out to be because
weston-terminal defaults to trying to spawn /bin/bash, which my
busybox-based system didn't have.
I can configure the terminal to use a shell I do have, of course, but I
think /bin/sh is a much friendlier default, because it's more likely to
exist (POSIX requires it), and will save people just trying to get
started with Weston from the confusing experience I had. I think it's
better overall that somebody who specifically wants /bin/bash has to
configure that (if they even have to — depending on how they're running
Weston, $SHELL might already be /bin/bash) than somebody who just wants
to see the terminal working debug why it won't launch at all.

Trying to run viewporter-test with ASan leak checking,
weston-desktop-shell helper client reports many leaks, because the

Clean up by calling display_destroy() when wl_display_roundtrip() fails.
It's late enough that all kinds of things may have been allocated, so a
special local tear-down path is not feasible.
To make that work, display_destroy() must handle many things that might
be NULL which normally aren't. Also display_create() needs to initialize
lists early enough so that cleaning them up works.

Currently, Weston clients update the pointer cursor by first issuing
a wl_surface.commit request to update the buffer, then a
wl_pointer.set_cursor request to update the hotspot. This causes an
issue because buffer and hotspot aren't updated atomically: in-between
the two requests, the buffer is new but the hotspot is old.
To fix this issue, create a new surface each time the cursor is
updated.

While this is harmless because gbm_bo_create_with_modifiers will just
fail, it's easy to misunderstand that gbm_bo_create_with_modifiers
accepts MOD_INVALID. Let's just keep modifiers_count to zero instead
and stop even trying to call that function with invalid input.
Stop using modifiers_count to decide whether the compositor supports a
format. Instead use a separate format_supported flag.

This header is for sharing fallback definitions for drm_fourcc.h. A new
test in tests/yuv-buffer-test.c is going to be needing XYUV8888 format,
and more new formats will be expected with HDR supports.
Share these fallback definitions in one place instead of copying them
all over.
All users of drm_fourcc.h are converted to include weston-drm-fourcc.h
instead for consistency: have the same definitions available everywhere.

MOD_INVALID came with libdrm 2.4.83 and MOD_LINEAR came with libdrm
2.4.82. libweston unconditionally depends on libdrm >= 2.4.95, so the
fallback is not necessary.
Since linux-dmabuf.h itself has no use for these and also forgets to
include drm_fourcc.h, .c files including drm_fourcc.h after this header
would trigger compiler warnings.
linux-dmabuf.c does need these, so add the proper include.

We have two functions with the name weston_screenshooter_shoot():
1. screenshot protocol function that the screenshooter
client uses to request screenshots to the compositor
2. libweston function used by the compositor to take
screenshots as requested by the screenshooter client
Until now we had no problem with that, but in the next commits
we are going to use the screenshot protocol in the test suite,
which is also user of libweston. So rename screenshot protocol
function to weston_screenshooter_take_shot() to avoid the conflict.
For consistency, also rename screenshooter_shoot() to
screenshooter_take_shot() in compositor/weston-screenshooter.c

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.

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.

Makes use of weston-direct-display protocol to pass the dmabuf
straight to the display-controller if such a path is possible.
Removes the Y_INVERT flag in case that was passed, and notifies
the user about it, as the weston implementation would force going
through the renderer when passing the Y_INVERT flag, but in the same
time direct-display avoids any GPU import so having them both in the
same time would result into weston refusing the create a buffer.

Allow clients to pass Y_INVERT, not only when v4l reports it so.
Document it briefly and add a note about this Y_INVERT flag is passed
if the camera sensors is detected as being y-flipped.
