weston_client_start() is a new wrapper around weston_client_launch(),
that does the process tracking on its own, and logs the process exit
status.
When users of weston_client_start() want to know when the process exits,
they should hook into the wl_client destroy signal. This works for cases
where the client is not expected to disconnect without exiting.
As wl_client destructor and the sigchld handler run in arbitary order,
it is usually difficult for users to maintain both struct weston_process
and a struct wl_client pointer. You would need to wait for both
destructor and handler to have run, before attempting to respawn the
client.
This new function relieves the caller from the burden of maintaining the
struct weston_process, assuming the caller is only interested in client
disconnects.

It looks like that in the great conversion introducing weston_view, one
conditional was forgotten from the code that builds the global flat list
of views. Sub-surfaces are added to the view list specially, as they are
not governed by their presence in a layer's view list, and therefore
need an explicit check for mappedness.
The bug, missing the explicit check, caused sub-surfaces to enter the
global view_list regardless of their state. This lead to the pointer
focus picking code processing them, and as the input region defaults to
infinite, picking these unmapped surfaces. Clients then get confused
about the wl_pointer.enter events with unexpected wl_surface.
To trigger this issue, it is enough to just create one additional
wl_surface and make it a sub-surface of a main surface that is or gets
mapped. Literally, just a wl_subsomcpositor_get_subsurface() call is
enough. At some point later, the unmapped sub-surface will get pointer
focus, depending on view stacking order.
Fix the issue by adding a is_mapped check when building the view_list.
Note, that 95ec0f95aa accidentally also
prevents this bug from happening, because it adds a test against the
transform.masked_boundingbox in weston_compositor_pick_view().

If a client does this:
1. create a main window and map it
2. create a wl_surface, and make it a sub-surface of the main window
3. set the sub-surface to desync
4. commit content to the sub-surface to map it
Then step 4 should cause the sub-surface to become mapped. However,
Weston fails to schedule a repaint in that case, so the sub-surface will
not appear until something else causes a repaint on that output, e.g.
the main window.
A quick and dirty fix is to set the output mask for the surface in
Weston, which allows the repaint to be scheduled. This patch implements
that, and might only work right on single-output systems.
A proper fix would involve rewriting the whole "is surface mapped"
mechanism in Weston, to not rely on output assignments but to have a
separate flag for "mapped", and figuring out how to schedule repaints
for the right outputs.

this adds a mechanism to mask the views belonging to a layer
to an arbitrary rect, in the global space. The parts that don't fit
in that rect will be clipped away.
Supported by the gl and pixman renderer only for now.
This introduces a new struct, weston_layer_entry, which is now used
in place of wl_list to keep the link for the layer list in weston_view
and the head of the list in weston_layer.
weston_layer_entry also has a weston_layer*, which points to the layer
the view is in or, in the case the entry it's the head of the list, to
the layer itself.
This new structure is used for both weston_surface.pending and
weston_subsurface.cached.

The zoom translation is just a scale and a translate. The translation
is calculated based on the coordinates of the pointer which are in
global space. Previously the calculated translation was transformed by
the output transformation so that when the zoom transform is applied
after the output transform then it will be correct. However if we just
apply the zoom transformation first then we get the same result
without the zoom code having to be aware of the output transformation.
This also fixes weston_output_transform_coordinate which was applying
the output and zoom transforms in the wrong order.
https://bugs.freedesktop.org/show_bug.cgi?id=78211
When converting output-relative coordinates (such as from an input
event) to global coordinates it now takes into account the zoom
transform. Previously this would only work for the primary pointer
because the transform doesn't affect the primary pointer position due
to that way zoom follows the mouse. Touch events and multiple pointers
were not working correctly.
https://bugs.freedesktop.org/show_bug.cgi?id=68620
In order to apply the zoom transformation to the output matrix, Weston was
doing the following:
• Create a temporary matrix to hold the translation
• Invert the translation matrix using weston_matrix_invert into
another temporary matrix
• Scale that matrix by the scale factor
• Multiply the current matrix with the temporary matrix
Using weston_matrix_invert to invert a translation matrix is over the top.
Instead we can just negate the values we pass to weston_matrix_translate.
Matrix multiplication is associative so creating a temporary matrix to hold the
scale and translation transform should be equivalent to just applying them
directly to the output matrix.
Previously, because of the wrong width/height,
weston_surface_to_buffer_* would return the wrong values when
wl_viewport was used in combination with wl_surface.set_buffer_transform.

destination size is not set and source size is zero. Previously this

Let's make the source and destination size rules consistent: neither can
have zero, {-1, -1} disables it, and other negatives are not allowed.
The sanity of allowing zero sized source rectangle as debatable. Now the
minimum becomes 1/256x1/256, and with output_scale the actual samples
may be even smaller. That should be enough.
On not allowed values, raise a protocol error. This should help catch
bugs in clients that accidentally send garbage values.
The old wl_viewport.set request remains the same, and can still produce
zero sized source rectangle.

This patch adds an option to the RDP compositor to disable
desktop resizes initiated by RDP peer. The current behaviour
is that if an incoming RDP peer suggests a resolution that is
not the current one, a mode_switch() is done and the desktop is
resized to that new resolution. This new flag allows to disable
that behaviour. If the flag is set, the new behaviour is that the
RDP peer will be instructed to resize to the size of the desktop.

Remove the explicit boolean variable, and use illegal width to denote
"not set".
Split the boolean into two, so we can later start having buffer.src_*

At the moment, both buffer.src_width and surface.width conditions are

This was always a little iffy. At least it could have been a signal,
but we now have focus signal, so lets just use that. We lose
the ability to detect unresponsive clients at key event time, but we
could add that back by adding a key_signal.
Remove the listener for output destroy from weston_view and instead
iterate views owned by the shell in its own output destroy listener.
This simplifies the code a bit since keeping the view listening for the
destroy on the right output was a bit complicated. This also removes the
function pointer output_destroyed from weston_view. The only user for it
was desktop shell, but now this is all handled in shell.c.
Since that signal is per output, it is necessary to track in which
output a view is in so that the signal is handled properly.
Instead, add a compositor wide output moved signal, that is handled by
the shell. The shell iterates over the layers it owns to move views
appropriately.
If only the mode or the owner are wrong, do not say both are wrong.
Change the text to state that there's a problem and the current
values, and let the user figure it out.

This fixes a regression caused by either 918f2dd4 or da75ee1d. In
particular, if a client called commit without attaching a buffer and if the
compositor had already released its reference to the buffer, then a size of
0x0 would be set on the surface. In particular, this affects the wayland
backend because it frequently sends only a frame request in order to cause

Currently we destroy the renderer before the outputs are destroyed, but
that sometimes leads to an error since a reference to the renderer is
necessary in order to destroy a gl_renderer_output.
Since destroying the renderer is common among all backends, just move
that call into weston_compositor_shutdown() immediately after the
outputs being destroyed.
Remove those listeners when the output is destroyed, otherwise they'll
point to invalid data that may lead to corruption when assigning a new
output for the view.
