dc0f73bcac shell: Encapsulate weston_curtain in its own struct
This will allow us to create a solid weston_buffer as well, since we
need to store that separately.

e031397e09 desktop-shell: Reuse curtains for focus animations
Just as we do for fullscreen backgrounds, reuse the curtain infrastructure
for focus animations.

This introduces a small functional change, in that the surface's output
is no longer directly assigned. Instead, we call
weston_view_set_output() ourselves. As setting the weston_view's
position (done from the common helper function of weston_curtain_create
which has been introduced in previous commits) will call
weston_view_set_position(), the view's geometry will be dirtied as a
result.

When the geometry of a weston_view is dirty, it is marked to be updated,
which will occur whilst traversing the view list during output repaint.
This occurs for every view which is currently assigned to a layer; when
building the view list, any view reachable through the view list whose
geometry is dirty will have its position recalculated and an output
assigned. Doing so results in the surface's current output being
updated.

It is believed that there is no functional impact from the
weston_surface not having a primary output assigned between creation and
output repaint being called.

64ef87554b desktop-shell: Clean up fullscreen black view code
Rationalise it a little bit so we don't need pre-declarations of static
functions, and the order of creation more closely matches the others,
including making the same calls to explicitly set the output.

Doing this makes the behaviour match the other users of the same code
pattern. In making them the same, we make desktop-shell code a little
less magically divergent where people might wonder what the correct
pattern is to use. After we have moved all users to a uniform pattern,
later commits are then able to migrate these users to common helper
code, which reduces code duplication, improves code clarity as it is no
longer necessary to wonder about the exact semantics of every
special-case user of this common pattern, and makes it easier to make
interface changes which improve and clarify the patterns which are
prevalent throughout the desktop-shell code.

d21563360a shell: Move weston_curtain_create params into the struct
Given that we have a struct for argument params, we might as well use it
rather than have them split between the struct and native params. For
consistency between the implementations, this also includes a shift from
float to int positioning for the base offset within the compositor's

66374d48f1 compositor: Remove desktop zoom
Zoom is a neat trick, but in its current form it's very hard to test

It also causes output damage to scale outside of the output's boundaries,
which leads to an extra clipping step that's only necessary when zoom
is enabled.

137c793f22 desktop-shell: Guard against invalid seats in get_shell_seat()
Starting with commit 'desktop-shell: Embed keyboard focus handle code
when activating' we are iterating over all the seats when removing a
weston_desktop_surface to be able to invalidate the activate surface.

Upon compositor tear down the shell destroy might invalidate seats
before removal of the weston_desktop_surface making the shell_seat
itself invalid. This wasn't apparent at that time because we're not
handling at that the removal of surfaces from layers.

04918f3b0b desktop-shell: don't run fade animation if compositor is inactive
When a window is closed, Weston will, by default, run a fade out animation and
defer destroying the underlying surface until it completes. However, if the
compositor is sleeping, and therefore not rendering any frames, this animation
will *never* complete. Therefore, if windows are repeatedly created and
destroyed while in sleep mode, these surfaces will keep accumulating, and since
the buffers attached to them may be backed by an fd, eventually the ulimit will
be reached resulting in a potential crash or other errors.

This can be demonstrated repeatedly launching and killing an X11 application
with Xwayland running.

while true; do xterm & pid=$!; sleep 0.5; kill $pid; done

As soon as the compositor goes to sleep, one can observe a steadily growing
list of dmabufs in the output of lsof.

As a fix, desktop_surface_removed should check whether the compositor is active
before kicking off the fade animation. If it is not, it should instead drop the
extra reference taken in desktop_surface_committed and then destroy the surface
immediately.

2ac73a8b53 exposay: delete outer padding from struct exposay_output
After some changes in the exposay layout, the outer padding makes
no sense anymore. It was used to avoid the panel to get overlapped
by the exposay surfaces and to keep distance from the borders
of the window.

Currently, the exposay is centralized and the panel cannot get
overlapped. The outer padding just creates unnecessary unused
space, what makes exposay's surfaces smaller.

Delete outer padding from struct exposay_output.

The cms-static, desktop-shell, hmi-controller, ivi-shell, and screen-share

  	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

6ffbba3ac1 Use weston_compositor_add_destroy_listener_once() in plugins
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 have two kinds of libweston users: internal and external. Weston, the

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.

14ef201295 desktop-shell: don't crash if a surface disappears while grabbed
A surface can get destroyed while a shell grab is active, which can
for example happen if the command running in weston-terminal exits.

When a surface gets destroyed, grab->shsurf is reset to NULL by
destroy_shell_grab_shsurf(), but otherwise the grab remains active and
its callbacks continue to be called. Thus, dereferencing grab->shsurf
in a callback without checking it for NULL first can lead to undefined
behavior, including crashes.

Several functions were already properly checking grab->shsurf for NULL,
move_grab_motion() being one example. Others, however, were not, which
is what this commit fixes.

8011b0fa03 Add Meson build system
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.

receive width=0 and height=0 in the configure event, which means the
client is free to choose the size. There is no correct size to send for
maximizing for no output.

In constrain_position(), this has no effect. The interactive move of a
surface is restricted to not go below the panel, so even if a user
managed to move a surface without an output, it just prevents the
surface moving beyond y=0.

In weston_view_set_initial_position(), get_output_work_area() will not
be called with NULL output anyway.

In set_maximized_position(), this makes it behave as if the output was
at 0,0 which is the default position of the first output.

e7a52fbb7d libweston: add weston_view_set_output()
Instead of desktop shell assigning view outputs directly,
use a new method, weston_view_set_output(). The method can
set up an output destroy listener to make sure that views
do not have stale output pointers.

Without this patch it is possible to end up in a scenario
where, e.g. configure_static_view() accesses memory that
has already been freed. The scenario can be provoked by
repeatedly plugging and unplugging a display. The faulty
memory accesses are reported by valgrind.

055c1137ae libweston: make wl_output point to weston_head
The user data of a wl_resource representing a wl_output protocol object
used to be a pointer to weston_output. Now that weston_output is being
split, wl_output more accurately refers to weston_head which is a single
monitor.

Change the wl_output user data to point to weston_head.
weston_output_from_resource() is replaced with
weston_head_from_resource().

This change is not strictly necessary, but architecturally it is the
right thing to do. In the future there might appear the need to refer to
a specific head of a cloned pair, for instance.

If for some reason the helper client weston-desktop-shell would create

Instead, do not store the new, redundant panel surface and do not

Our case is when the view is the same as output being disabled/disconnected.
There's not need to check the views' output with the output being disabled
because weston_view_assign_output() already changes the output of the view when
the output has been disabled/disconnected hence the check is not needed at all.

The views' output will always be different than the output being disabled.

already changed to a "free" output. Tested this by unplugging/disabling the

Regression: kcachegrind (Qt 4, X11), the first menu invocation will

drawing decorations and Xwayland committing the first buffer.

d3a3ee980d desktop-shell: Unset the shell surface owner when it goes away
On client destruction, the shell object may be destroyed before the
shell surface objects. If this happens to two surfaces of the same
client, and one surface being destroyed results in the focus being
switched to the other, this would trigger a ping event.

The ping event sending function relies on having a valid owner, and if
the shell would be destoryed prior to the shell surface, we'd crash in
this function.

Solve this by unsetting the owner pointer when the shell client goes
away and early out in the ping event sending function if the owner is
gone.

The click_to_activate handler fires on every mouse click for a surface
so let's be a little quicker to early return if you're clicking on the

This prevents (among other side effects) the sending of two xdg_configure
events for every mouse click.

This should also make having two seats with keyboards behave in the same
way as a single seat.  Previously the second seat could have a keyboard
focus on the surface and prevent some of the extra processing (including
the extra configure events) from taking place.

Valgrind has shown that in at least one place (default_grab_pointer_focus)

This is happening when default_grab_pointer_focus is called when there is
nothing on the view list, and during the first repaint when only the black
surface with no input region exists.

This patch adds a function to clear pointer focus and also set the sx,sy
co-ordinates to a sentinel value we shouldn't compute with.

Assertions are added to make sure any time pointer focus is set to NULL
these values are used.

weston_compositor_pick_view() now returns these values too.

Now the values are always initialized, even when no view exists, and
they're initialized in such a way that actually doing computation
with them should fail in an obvious way, but we can compare them
safely for equality.

1281a36e3b input: Don't test keyboard/pointer/touch pointers
Keyboards and pointers aren't freed when devices are removed, so we should
really be testing keyboard_device_count and pointer_device_count in most
cases, not the actual pointers. Otherwise we end up with different
behaviour after removing a device than we had before it was inserted.

This commit renames the touch/keyboard/pointer pointers and adds helper
functions to get them that hide this complexity and return NULL when
*_device_count is 0.

seat->keyboard_focus_listener.link isn't a head, it's just sometimes a

Instead, we remove the item then init it.  That way we can call remove on
it again later even if it hasn't been re-added to a list.

Track the seat that initiated a seat instead of picking the first one.

Previously, if there are multiple seats then any seat can adjust the zoom
level but the zoom tracks the first seat's pointer.

Now the zoom will follow the pointer of the seat that initiated the zoom.

Additionally, if there's no pointer in the first seat, starting a zoom
with the second seat will no longer crash weston.

8ae2db5b0c input: Pass the appropriate pointer type to bindings instead of a seat
Normally we need to check if a seat's [device_type]_count is > 0 before
we can use the associated pointer.  However, in a binding you're
guaranteed that the seat has a device of that type.  If we pass in
that type instead of the seat, it's obvious we don't have to test it.

The bindings can still get the seat pointer via whatever->seat if they
need it.

This is preparation for a follow up patch that prevents direct access
to seat->device_type pointers, and this will save us a few tests at
that point.

This way toplevel fullscreen surfaces can mode-switch their output

fullscreen status, but effects like window switching and exposay
still work in the expected way.

9f4d655494 desktop-shell: Allow multiple active fullscreen windows on multi-display setup.
Desktop shell demoted all fullscreen shell surfaces on all active

fullscreen windows on separate outputs active at the same
time, as creating or activating any shell surface would disable
fullscreen status for all existing fullscreen surfaces.

Make lower_fullscreen_layer() more selective, so on request it
only demotes fullscreen surfaces on a specified weston_output.

The activate() method for a specific surface will now only request
demotion of fullscreen surfaces on the target output of the activated
surface, but leave fullscreen surfaces on unrelated outputs alone.

Desktop wide acting functions like the window switcher or exposay
will still demote all fullscreen surfaces on all outputs to
implement their effect as before.

aa9536a992 text_backend: make destructor call explicit

Looking at the first of these, unbind_input_panel() gets called when the
text-backend destroys its helper client which has bound to input_panel
interface. This happens after the shell's destroy_signal callback has
been called, so the shell has already been freed.

The other two errors come from
  wl_list_remove(&input_panel_surface->link);
which has gone stale when the shell was destroyed
(shell->input_panel.surfaces list).

Rather than creating even more destroy listeners and hooking them up in
spaghetti, modify text-backend to not hook up to the compositor destroy
signal. Instead, make it the text_backend_init() callers' responsibility
to also call text_backend_destroy() appropriately, before the shell goes
away.

This fixed all the above Valgrind errors, and avoid a crash with
ivi-shell when exiting Weston.

Also using desktop-shell exhibited similar Valgrind errors which are
fixed by this patch, but those didn't happen to cause any crashes AFAIK.

b37ac4006a desktop-shell: remove screensaver support
This is a follow-up for the patch that removed weston-screensaver. The
aim is to clean up shell.c a little by removing non-essential
components. Vanilla Weston desktop is only a demo, external projects are
encouraged to create user-friendly desktop environments.

The support for launching a screensaver client and the protocol bindings
are removed. With them, all related configuration options are removed,
and the manuals are updated accordingly.

The screensaver protocol definition is left in desktop-shell.xml for
posterity.

This does not affect Weston's or desktop-shells ability to put screens
to sleep after inactivity. The inactivity timer continues to operate as
before. Also screen locking is unaffected.
