1549e30372 Add a Meson build system alongside autotools.
This is a work in progress that builds Xvfb, Xephyr, Xwayland, Xnest,
and Xdmx so far.  The outline of Xquartz/Xwin support is in tree, but
hasn't been built yet.  The unit tests are also not done.

The intent is to build this as a complete replacement for the
autotools system, then eventually replace autotools.  meson is faster
to generate the build, faster to run the bulid, shorter to write the
build files in, and less error-prone than autotools.

v2: Fix indentation nits, move version declaration to project(), use
    existing meson_options for version-config.h's vendor name/web.

d4b7e0eaa4 xwayland: clear cursor frame callback
After an X cursor is unrealized, the seat's corresponding x_cursor is

remain and thus prevent any further cursor update, leaving the window

that next time a cursor needs to be set, it won't be ignored for a frame
callback that will never be triggered.

fe5c340046 xwayland: do not set checkRepeat on master kbd
keyboard_check_repeat() fetches the XWayland seat from the
dev->public.devicePrivate do do its thing.

If a key event is sent programmatically through Xtest, our device is the
virtual core keyboard and that has a dev->public.devicePrivate of NULL,
leading to a segfault in keyboard_check_repeat().

This is the case with "antimicro" which sends key events based on the
joystick buttons.

Don't set the checkRepeat handler on the VCK since it cannot possibly work
anyway and it has no effect on the actual checkRepeat intended functionality.

9f4d308cda xwayland: use _XWAYLAND_ALLOW_COMMITS property
The X11 window manager (XWM) of a Wayland compositor can use the
_XWAYLAND_ALLOW_COMMITS property to control when Xwayland sends
wl_surface.commit requests. If the property is not set, the behaviour
remains what it was.

XWM uses the property to inhibit commits until the window is ready to be
shown. This gives XWM time to set up the window decorations and internal
state before Xwayland does the first commit. XWM can use this to ensure
the first commit carries fully drawn decorations and the window
management state is correct when the window becomes visible.

Setting the property to zero inhibits further commits, and setting it to
non-zero allows commits. Deleting the property allows commits.

When the property is changed from zero to non-zero, there will be a
commit on next block_handler() call provided that some damage has been
recorded.

Without this patch (i.e. with the old behaviour) Xwayland can and will
commit the surface very soon as the application window has been realized
and drawn into.  This races with XWM and may cause visible glitches.

v3:
- introduced a simple setter for xwl_window::allow_commits
- split xwl_window_property_allow_commits() out of
  xwl_property_callback()
- check MakeAtom(_XWAYLAND_ALLOW_COMMITS)

v2:
- use PropertyStateCallback instead of XACE, based on the patch
  "xwayland: Track per-window support for netwm frame sync" by
  Adam Jackson
- check property type is XA_CARDINAL
- drop a useless memcpy()

058809c43e xwayland: Apply output rotation for screen size
Previously, we would swap the width/height of the Xwayland output based
on the output rotation, so that the overall screen size would match the
actual rotation of each output.

Problem is the RandR's ConstrainCursorHarder() handler will also apply
the output rotation, meaning that when the output is rotated, the
pointer will be constrained within the wrong dimension.

Moreover, XRandR assumes the original output width/height are unchanged
when the output is rotated, so by changing the Xwayland output width and
height based on rotation, Xwayland causes XRandr to report the wrong
output sizes (an output of size 1024x768 rotated left or right should
remain 1024x768, not 768x1024).

So to avoid this issue and keep things consistent between Wayland and
Xwayland outputs, leave the actual width/height unchanged but apply the
rotation when computing the screen size. This fixes both the output size
being wrong in "xrandr -q" and the pointer being constrained in the
wrong dimension with rotated with weston.

However, if the rotation is not supported by the CRTC, this is not

Pretend we support all rotations and reflections so that the
configuration remains a valid xrandr setup.

59ad0e6a41 xwayland: Fix use after free of cursors
Sometimes, Xwayland will try to use a cursor that has just been freed,
leading to a crash when trying to access that cursor data either in
miPointerUpdateSprite() or AnimCurTimerNotify().

CheckMotion() updates the pointer's cursor based on which xwindow
XYToWindow() returns, and Xwayland implements its own xwl_xy_to_window()
to fake a crossing to the root window when the pointer has left the
Wayland surface but is still within the xwindow.

But after an xwindow is unrealized, the last xwindow used to match the
xwindows is cleared so two consecutive calls to xwl_xy_to_window() may
not return the same xwindow.

To avoid this issue, update the last_xwindow based on enter and leave
notifications instead of xwl_xy_to_window(), and check if the xwindow
found by the regular miXYToWindow() is a child of the known last
xwindow, so that multiple consecutive calls to xwl_xy_to_window()
return the same xwindow, being either the one found by miXYToWindow()
or the root window.

5611585b87 xwayland: Don't send KeyRelease events on wl_keyboard::leave
Commits 816015648f and
fee0827a9a made it so that
wl_keyboard::enter doesn't result in X clients getting KeyPress events
while still updating our internal xkb state to be in sync with the
host compositor.

wl_keyboard::leave needs to be handled in the same way as its
semantics from an X client POV should be the same as an X grab getting
triggered, i.e. X clients shouldn't get KeyRelease events for keys
that are still down at that point.

This patch uses LeaveNotify for these events on wl_keyboard::leave and
changes the current use of KeymapNotify to EnterNotify instead just to
keep some symmetry between both cases.

On ProcessDeviceEvent() we still need to deactivate X grabs if needed
for KeyReleases.

007f8ee61a xwayland: Activate and enable touch devices
On some random condition, a touch event may trigger a crash in Xwayland
in GetTouchEvents().

The (simplified) backtrace goes as follow:

 (gdb) bt
 #0  GetTouchEvents() at getevents.c:1892
 #1  QueueTouchEvents() at getevents.c:1866
 #2  xwl_touch_send_event() at xwayland-input.c:652

 #6  dispatch_event() from libwayland-client.so.0

 #11 Dispatch() at dispatch.c:412
 #12 dix_main() at main.c:287
 #13 __libc_start_main() at libc-start.c:289
 #14 _start ()

The crash occurs when trying to access the sprite associated with the
touch device, which appears to be NULL. Reason being the device itself
is more a keyboard device than a touch device.

Moreover, it appears the device is neither enabled nor activated
(inited=0, enabled=0) which doesn't seem right, but matches the code in
init_touch() from xwayland-input.c which would enable the device if it
was previously existing and otherwise would create the device but not
activate it.

Make sure we do activate and enable touch devices just like we do for
other input devices such as keyboard and pointer.

a6e85e6330 xwayland: Add pointer warp emulator
Emulate pointer warps by locking the pointer and sending relative
motion events instead of absolute. X will keep track of the "fake"
pointer cursor position given the relative motion events, and the
client warping the cursor will warp the faked cursor position.

Various requirements need to be met for the pointer warp emulator to
enable:

The cursor must be invisible: since it would not be acceptable that a
fake cursor position would be different from the visual representation
of the cursor, emulation can only be done when there is no visual
representation done by the Wayland compositor. Thus, for the emulator
to enable, the cursor must be hidden, and would the cursor be displayed
while the emulator is active, the emulator would be destroyed.

The window that is warped within must be likely to have pointer focus.
For example, warping outside of the window region will be ignored.

The pointer warp emulator will disable itself once the fake cursor
position leaves the window region, or the cursor is made visible.

This makes various games depending on pointer warping (such as 3D
first-person shooters and stategy games using click-to-drag-map like
things) work.

ee52628588 xwayland: Apply "last pointer window" check only to the pointer device
The checks in xwayland's XYToWindow handler pretty much assumes that the
sprite is managed by the wl_pointer, which is not entirely right, given
1) The Virtual Core Pointer may be controlled from other interfaces, and
2) there may be other SpriteRecs than the VCP's.

This makes XYToWindow calls return a sprite trace with just the root
window if any of those two assumptions are broken, eg. on touch events.

So turn the check upside down, first assume that the default XYToWindow
proc behavior is right, and later cut down the spriteTrace if the
current device happens to be the pointer and is out of focus. We work
our way to the device's lastSlave here so as not to break assumption #1
above.

862a3dab28 xwayland: Clear up x_cursor on UnrealizeCursor()
In Xwayland's xwl_unrealize_cursor(), the x_cursor is cleared up only
when a device value is provided to the UnrealizeCursor() routine, but
if the device is NULL as called from FreeCursor(), the corresponding
x_cursor for the xwl_seat is left untouched.

This might cause a segfault when trying to access the unrealized
cursor's devPrivates in xwl_seat_set_cursor().

A possible occurrence of this is the client changing the cursor, the
Xserver calling FreeCursor() which does UnrealizeCursor() and then
the Wayland server sending a pointer enter event, which invokes
xwl_seat_set_cursor() while the seat's x_cursor has just been
unrealized.

To avoid this, walk through all the xwl_seats and clear up all x_cursor
matching the cursor being unrealized.

b79eaf1184 xwayland: handle EAGAIN on Wayland fd
wl_display_flush() can fail with EAGAIN and Xwayland would make this a
fatal error.

When this happens, it means that Xwayland has flooded the Wayland file
descriptor, either because the Wayland compositor cannot cope or more
likely because of a deadlock situation where the Wayland compositor is
blocking, waiting for an X reply while Xwayland tries to write data to
the Wayland file descriptor.

The general consensus to avoid the deadlock is for the Wayland
compositor to never issue blocking X11 roundtrips, but in practice
blocking rountrips can occur in various places, including Xlib calls
themselves so this is not always achievable without major surgery in the
Wayland compositor/Window manager.

What this patch does is to avoid dispatching to the Wayland file
descriptor until it becomes available for writing again, while at the
same time continue processing X11 requests to release the deadlock.

This is not perfect, as there is still the possibility of another X
client hammering the connection and we'll still fail writing to the
Wayland connection eventually, but this improves things enough to avoid
a 100% repeatable crash with vlc and gtkperf.

Also, it is worth considering that window managers and Wayland
compositors such as mutter already have a higher priority than other
regular X clients thanks to XSyncSetPriority(), mitigating the risk.

589f42e983 xwayland: Process queued events before making wayland mods effective
Since xwayland's initial commit we have had a check to not process
wayland modifier events while one of our surfaces has keyboard focus
since the normal xkb event processing keeps our internal modifier
state up to date and if we use the modifiers we get from the
compositor we mess up that state.

This was slightly changed in commit
10e9116b3f to allow the xkb group to be
set from the wayland event while we have focus in case the compositor
triggers a group switch.

There's a better solution to the original problem though. Processing
queued events before overriding the xkb state with the compositor's
allows those events to be sent properly modified to X clients while
any further events will be modified with the wayland modifiers as
intended.

This allows us to fully take in the wayland modifiers, including
depressed ones, which fixes an issue where we wouldn't be aware of
already pressed modifiers on enter.

Split xwl_output_destroy() into xwl_output_destroy() which frees the

does the RRCrtcDestroy() and RROutputDestroy() and call the latter only
when an output is effectively removed.

An additional benefit, on top of avoiding a double free, is to avoid
updating the screen size at shutdown.

7397a2191f xwayland-input: Fake crossing to rootwin
This partially reverts commit c1565f3.

When the pointer moves from an X11 window to a Wayland native window,
no LeaveNotify event is emitted which can lead to various unexpected
behaviors like tooltips remaining visible after the pointer has left the
window.

Yet the pointer_handle_leave() is called and so is the DIX CheckMotion()
but since the pointer enters a Wayland native window with no other
Xwayland window matching, DoEnterLeaveEvents() does not get invoked and
therefore no LeaveNotify event is sent to the X11 client at the time the
pointer leaves the window for a Wayland native surface.

Restore the XYToWindow() handler in xwayland-input that was previously
removed with commit c1565f3 and use that handler to pretend that the
pointer entered the root window in this case so that the LeaveNotify
event is emitted.

6a6bbc3b75 xwayland: Restore wl_display_roundtrip() in InitInput
This partially revert commit 984be78

The rountrip in Xwayland's InitInput() is unlikely the culprit for the
crash reported in bug 95337, even though it's triggered from
InitInput().

Startup goes like this:

  xwl_screen_init()
    xwl_output_create()
    wl_display_roundtrip()
  InitInput()
    wl_display_roundtrip()
  ConnectionInfo initialized

What happens in bug 95337 is that some output data is already available
when we reach InitInput()'s wl_display_roundtrip() and therefore we end
up trying to update the ConnectionInfo's data from RR routines before
ConnectionInfo is actually initialized.

Removing the wl_display_roundtrip() from InitInput() will not fix the
issue (although it would make it less lileky to happen), because
xwl_screen_init() also does a wl_display_roundtrip() after creating the
output, so the race that led to bug 95337 remains.

However, re-setting the xwl_screen->expecting_event to 0 again in
InitInput() still doesn't seem right. so this part is not restored
(thus a partial revert).

fact that CLOCK_MONOTONIC_COARSE has a lower resolution.

that it becomes possible for Wayland compositor only supporting

e957a2e5dd dix: Add hybrid full-size/empty-clip mode to SetRootClip
216bdbc735 removed the SetRootClip call in the XWayland output-hotplug
handler when running rootless (e.g. as a part of Weston/Mutter), since
the root window has no storage, so generating exposures will result in
writes to invalid memory.

Unfortunately, preventing the segfault also breaks sprite confinement.
SetRootClip updates winSize and borderSize for the root window, which
when combined with RRScreenSizeChanged calling ScreenRestructured,
generates a new sprite-confinment area to update it to the whole screen.

Removing this call results in the window geometry being reported
correctly, but winSize/borderSize never changing from their values at
startup, i.e. out of sync with the root window geometry / screen
information in the connection info / XRandR.

This patch introduces a hybrid mode, where we update winSize and
borderSize for the root window, enabling sprite confinement to work
correctly, but keep the clip emptied so exposures are never generated.

07941a50a5 xwayland: Always update the wl_pointer cursor on pointer focus
In Wayland, a client (in this case XWayland) should set the cursor
surface when it receives pointer focus. Not doing this will leave the
curser at whatever it was previously.

When running on XWayland, the X server will not be the entity that
controls what actual pointer cursor is displayed, and it wont be notified
about the pointer cursor changes done by the Wayland compositor. This
causes X11 clients running via XWayland to end up with incorrect pointer
cursors because the X server believes that, if the cursor was previously
set to the cursor C, if we receive Wayland pointer focus over window W
which also has the pointer cursor C, we do not need to update it. This
will cause us to end up with the wrong cursor if cursor C was not the
same one that was already set by the Wayland compositor.

This patch works around this by, when receiving pointer focus, getting
the private mipointer struct changing the "current sprite" pointer to
an invalid cursor in order to trigger the update path next time a cursor
is displayed by dix.

51984dddfc glamor: Delay making pixmaps shareable until we need to.
If a pixmap isn't getting exported as a dmabuf, then we don't need to

On Raspberry Pi, where scanout isn't usable as a texture source, this
improves x11perf -copypixwin100 from about 4300/sec to 5780/sec under
xcompmgr -a, because we no longer need to upload our x11perf window to

Since there is no guaranteed order between wl_keyboard key and

modifier we would wrongly unlock/unlatch. To prevent this, we ignore
locked and latched modifiers while any of our surfaces has keyboard

c1565f3ca6 xwayland-input: Remove our XYToWindow handler
This was built as a hack for simple Wayland compositors like Weston
which were lazy and didn't want to configure windows server-side when

Since comboboxes and menus are separate toplevel O-R windows, this hack
breaks input as it needs to be traced normally, not simply sent to the
focused window.

X11 toolkits really do need their windows to be configured correctly
for their O-R windows comboboxes or menus other things, so let's fix
the lazy compositors and remove this.

I have tested this patch with both Weston and Mutter and neither of
them require any changes, and it fixes comboboxes and menus.
