Commit 79849ef1d5fff9acd310cd68d59df0c7cf2cb28f had a typo in the
device property format check. This property is formated in 8-bit
items, not 32-bit.
This went unnoticed till now because some touchpads were still being
detected as such due to a second check below:
else if (strstr (name, "touchpad") != NULL)
source = CLUTTER_TOUCHPAD_DEVICE;

The paint opacity for a top level is always overridden to be the full
value, since it's a composited value and we want to paint our scene.
When clearing the stage framebuffer, though, we want to use the actual
opacity, if ClutterStage:use-alpha is set.
-1 is explicitly an invalid value to pass to eglSwapBuffersWithDamage,
and the specification admits as much:
If
eglSwapBuffersWithDamageEXT is called and <n_rects>, is less
than zero or <n_rects> is greater than zero but <rects> is
NULL, EGL_BAD_PARAMETER is generated.
Fix up our usage of SwapBuffersWithDamage to match the behavior in the
EGL specification.

These are just terrible API that we've been stringing along since the
0.x days. We cannot truly deprecate them, because they are, in some
cases, the only actual API to perform some operation, and porting all
the code in the world is not going to make us any friends.
For the time being, we use a deprecation notice in the documentation.
The macros are useless for language bindings, and are terribly unsafe
from C as well. There's always the option of using the GObject
properties they refer to, but it's more efficient to just have a simple
getter function.
While each stage has at most a GdkFrameClock, the same GdkFrameClock
instance may drive multiple stages per frame. This means that the
mapping between a GdkFrameClock and a ClutterStage is a 1:M one, not a
1:1.
We should store a list of stages associated to each frame clock
instance, so that we can iterate over it when we need to update the
stages.
This commit fixes redraws of applications using multiple stages,
especially when using clutter-gtk.
_cally_actor_get_top_level_origin() uses a compile time check
without runtime check, which will obviously fail when another
backend like wayland is used.

When multiple relative motion events are received and queued, we can't
base the relative => absolute motion conversion off of the stage pointer
position, since that is only updated when the queue is processed at
the beginning of each frame. The effect of trying to use the stage
pointer position was that subsequent motion events were effectively
dropped.
To improve things, switch to keeping track of the pointer position
ourselves in the evdev backend and adding to that.
This has the side effect of making the internal function
_clutter_input_device_set_coords not effect the internal coordinate
state of the evdev stage, but AFAICS there is nothing depending on that
so that should be fine.

There's no point in trying to go ahead if we don't have a context to
create the CoglOnscreen framebuffer, and Cogl will crash anyway if we
pass NULL to the constructor.
With server-side buffer allocation, buffers may be returned out of order
(e.g. they may be held onto by external references or hardware). As such
we may see older buffers the frame after we discard the history from
seeing a very young buffer. To overcome this we want to keep the history
in a ring so we can keep track of older entries without keeping an
unbounded list. After converting to a ring, the maximum buffer age
observed during testing was 5 (expected value of 4), but before we could
see ages as high as 9 due to the huge latency spikes caused by doing full
buffer redraws (compounded by external listeners doing readback on the
damaged areas, for example vnc, drm/udl, prime). For this reason, a
maximum age of 16 was chosen to be suitably large enough to prevent these
worst cases from taxing the system.

cogl provides an interface to pass along damage with the swap buffers

If the rectangle is allocate a size smaller than the border, drawing the
border will end up with negative coordinates, and will mess up the whole
thing. Since rectangles don't have a minimum preferred size, we cannot
rely on the allocation being big enough to contain the border and the
background color.
If the rectangle is smaller than the border width value, we just paint
the border color as well.
Point to ClutterImage, ClutterContent, and ClutterActor where needed, so
that developers trying to port their code will have a chance at figuring
out how.
Nobody has been compiling Clutter with profiling enabled in a long time.
UProf itself hasn't been updated in 5 years, and it still depends on
deprecated components like dbus-glib, with no port to GDBus in sight.
The profiling code was moderately useful in the past, but these days
it's probably better to profile Cogl than Clutter itself; timing
information can be extracted by the timestamp on each diagnostic message
that is now available by default in the CLUTTER_NOTE macro, and we can
add ad hoc counters where needed.
Add clutter_x11_set_use_stereo_stage() that can be called
before clutter_init() so that the CoglDisplay we create and all
stages created from that CoglDisplay will be created with a
stereo fbconfig.
This is done in clutter-x11 because of the similarity to the
existing clutter_x11_set_use_argb_visual(), and because it's
not clear without other examples whether the need to have
stereo enabled from before clutter_init() is universal or
somethign specific to GLX.
Cogl required version is increased to 1.20, which has the
required API.

The _clutter_stage_update_state() function is currently putting events
into the Clutter event queue. This leads to problems in the gdk
backend because there are assumptions upon the numbers of queued
events, and how many of them should be moved from the main event queue
to the ClutterStages' event queues.
This change triggers the processing of the state update events on the
stage directly, so the main event queue retains the expected number of
events.

The easing state is part of the AnimationInfo structure, which is stored
inside the GObject's datalist. Each instance frees the data stored there
during finalization, so there is no point for us to restore an easing
state (which may or may not be the last one) just to have everything
cleared out once we chain up to GObject's own finalize() implementation.
Bind the preferred size of an actor using a BindConstraint to the
preferred size of the source of the constraint, depending on the
coordinate of the constraint.
Constraints can only update an existing allocation, which means they
live only halfway through the layout management system used by Clutter;
this limitation makes it impossible, for instance, to query the
preferred size of an actor, if the actor is only using constraints to
manage its own size.
And move the only private ClutterConstraint method to it.
This commit also sneaks in a change that makes sense for the debugging
of the update_allocation() method, which checks if the allocation was
effectively changed.
The core pointer concept doesn't really exist anymore in an XI2 world,
so the clutter API is a bit of a mismatch with what X provides. Using
XIGetClientPointer doesn't really help, as far as i can tell the
semantics of XIGetClientPointer are essentially: Whatever the X server
picked when it had to reply with device-dependant data to a query
without a device specifier. Not very useful...
To make matters worse, whether XIGetClientPointer returns a valid
pointer depends on whether there has been a query that forced it to pick
one in the first place, making the whole thing pretty non-deterministic.
This patch changes things around such that instead of using
XIGetClientPointer to determine the core pointer, we simply pick the
first master pointer device. In practise this will essentially always
be the X virtual core pointer.

When merging multiple definitions it's possible that the ObjectInfo

We want to recompute the content box when changing the content instance,

Some actors want to have a preferred size driven by their content, not
by their children or by their fixed size.

enumeration so that clutter_actor_get_preferred_size() defers to the
ClutterContent's own preferred size.

In keyboard/mouse wireless combos, it is rather common for the mouse to
claim it contains the multimedia keys, this makes libinput enable both
the pointer and keyboard capabilities on this device, and Clutter thus
to create a keyboard ClutterInputDevice for it.

or maybe account for the fact that certain events can be sent from
seemingly unexpected device types. But this will bring a somewhat better
behavior on such devices.

Atlasing is fine for smaller textures, but once they get too large its
downsides outweight the benefits. At worst, the larger texture will end
up inside its own atlas, but at worst it will require copying and/or
resizing of an existing atlas.
The cut-off at 512x512 pixels is a bit arbitrary, and we can change it
at any point; it would be nice if we could get the texture limit from
Cogl, and then use a fraction of that size as the cut-off limit. Sadly,
that's not portable, and it's not guaranteed to work either.
For a variety of complicated reasons, ClutterText currently sets fields
on the PangoContext when creating a layout. This causes ClutterText to
behave somewhat erratically in certain cases, since the PangoContext is
currently shared between all actors.
GTK+ creates a PangoContext for every single GtkWidget, so it seems like
we should do the same here.
Move the private code that was previously in clutter-main.c into
clutter-actor.c and clean it up a bit. This gives every actor its own
PangoContext it can mutilate whenever it wants, at its heart's content.
https://bugzilla.gnome.org/show_bug.cgi?id=739050
clutter_set_font_flags already calls clutter_backend_set_font_options,

duplicate and unneeded code.

libinput_suspend() will trigger the removal of input devices, but also

The get_threshold_tigger_egde() method was renamed to fix the typo, but
it obviously broke the ABI. To be fair, nobody in the whole of Debian

put the old symbol back in — obviously, deprecated — as a wrapper to the
newly added one.
If the device manager is created and queried for the client pointer at
a very early stage in application lifetime, the device_id returned would

gets the server to device about the client pointer before we query it.

This reverts commit 398a7ac713.
We cannot really use the GDK backend without massive regressions inside
the input layer, like touch events and gestures. The GDK backend is not
entirely up to scratch, and it's late in the cycle.
Let's land this early in 3.15, and get it up to par with X11.
Quite a few people at Guadec complained of pinpoint being broken in
speaker+fullscreen mode, with slides being half displayed. It turns
out that the X11 backend of clutter was being used and this backend
assumes the size of the current monitor is the size of the X screen
(that's not the case with multiple monitors).
To work around the shortcomings of the X11 backend we should probably
position the GDK one before. GDK implements most of the logic the
ClutterStage needs and is probably more tested.

There may be odd situations where full gesture cancellation may be wanted at once
when the first touch is lifted and ::gesture-end is emitted on a gesture action.

clutter_stage_set_paint_callback() has the disadvantage that it only
works for a single caller, and subsequent callers will overwrite and
break previous callers. Replace it with an ::after-paint signal that is
emitted at the same point - after all painting for the stage is
completed but before the drawing is presented to the screen.
https://bugzilla.gnome.org/show_bug.cgi?id=732342
CLUTTER_ENTER/LEAVE might be processed too, leading to accounting of the
NULL sequence (ie. pointer) in the gesture, and fooling the gesture with
a static extra point that wouldn't go away.
https://bugzilla.gnome.org/show_bug.cgi?id=732235
Until now, touch events sort of rely on XI_Enter/XI_Leave events accompanying
the pointer emulating touch in order to have a stage set on the device, These
events won't happen though if it's not a pointer emulating touch which happens
on the stage, causing touch events to be ignored.
Fix this by ensuring that the input device has a stage on XI_TouchBegin itself,
but only if it's not already set, so we don't possibly steal touch events to
an already interacting stage.
https://bugzilla.gnome.org/show_bug.cgi?id=732234
On X11 the pointer will follow a "pointer emulating" touch sequence, so the
pointer will be effectively left inside the stage after that touch is lifted,
even though the master device stage is unset. This makes pointer events get
ignored until the pointer leaves and enters again the stage.

Let's cross fingers and hope nobody notices. If this went unnoticed so far, likely
means this function has never been used. If any complain is raised about this, a
stub function should be added (and marked deprecated).
Those are translated into CLUTTER_TOUCH_* ClutterEvents. As the
"NULL" ClutterEventSequence is special cased, the slot=0 value is
avoided.
Frame events are ignored, as there is no Clutter equivalence, and
Cancel events are sent to all current individual touches.
https://bugzilla.gnome.org/show_bug.cgi?id=728968
And ensure the core pointer shares the same stage than the slave
device when those events are set. This fixes problems on the evdev

By creating and starting the timer on clutter_main() an assumption is made
that that is how the main loop will be run for all clutter applications.
With more and more applications moving to GApplication, this assumption no
longer holds true.
Moving to clutter_init() means we are starting the timer earlier than we
should, and by not stopping it when the main loop quits we are taking a
measure that is later than we should. I believe it is safe to consider
those are close enough to the actual beginning and quitting of the main

...so that its entries will reflect the entries that are checked by the
autotools builds on config.h.in. Also take into consideration for MinGW
builds and for newer Visual Studio versions, such as the availability for
inttypes.h. Update the layout of the file cosmetic-wise as well.
Clutter, like GTK+ and GLib, has recently switched to a visibility-based
method of exporting symbols, so update the Visual Studio build files to
do likewise, by using __declspec (dllexport). This eliminats the need to
use a .def file to export the symbols. The pre-configured
config.h.win32.in is also updated accordingly for this purpose. The
clutter.symbols file can be dropped if it is not being used otherwise.
Instead of listing every public symbol inside an ancillary file, we can
use compiler annotations. This scheme is also used by GLib and GTK+.
The symbols file is left in tree until the Visual Studio rules are
fixed, but it's not used any more during distcheck.
I double-checked that the exposed ABI is the same before and after this
change, except for symbols that were never meant to be public in the
first place, and that escaped our attention when we generated the first
version of the symbols file.
All backends follow the same pattern of queueing events first in
ClutterMainContext, then copying them to a ClutterStage queue and
immediately free them. Instead, we can just pass ownership of events
directly to ClutterStage thus avoiding the allocation and copy in
between.

itself and the text direction of the widget, in case that fails.

Currently clutter_device_manager_xi2_get_core_device always
does a round trip to query the client.
So avoid that by caching the client pointer and only update it when the
xi devices change.

ClutterInputDevice's default initial coordinates is (-1, -1) and since
they're updated from events in a relative way it means that the
pointer can go outside the stage right from the first event.
We usually let this up to higher layers to fix through the pointer
constraint callback but that doesn't work if the first event doesn't
put the pointer immediately inside the stage.

Doing so is unlikely to work reliably. Instead, switching the keymap
should be done at a time when no key is currently pressed down, but
let's leave that task to higher level code.
This allows us to remove key state tracking at yet another level in
the stack since higher level code likely already tracks this for other
purposes.

The kernel keyboard repeat functionality isn't configurable and
libinput rightfully ignores it.
This implements keyboard repeat in userspace allowing for consumers to
set the initial delay and repeat intervals.

The evdev backend has always been excluded from Clutter's API
stability guarantee though in an informal way. This commit makes it
explicit by forcing users to define CLUTTER_ENABLE_COMPOSITOR_API.

Instead of having its own evdev input device processing implementation,
make clutter's evdev backend use libinput to do input device processing
for it.
Two GObject parameters of ClutterInputDeviceEvdev (sysfs-path and
device-path) are removed as they are not used any more.
Before ClutterDeviceManagerEvdev had one virtual core keyboard and one
virtual core pointer device. These are now instead separated into seats,
which all have one virtual core keyboard and pointer device respectively.
The 'global' core keyboard and pointer device are the core keyboard and
pointer device of the first seat that is created.
A ClutterInputDeviceEvdev can, as before, both represent a real physical
device or a virtual device, but is now instead created either via
_clutter_input_device_evdev_new() for real devices, and
_clutter_input_device_new_virtual() for virtual devices.
XKB state and button state is moved to the seat structure and is thus
separated per seat. Seats are not a concept exposed outside of clutter's
evdev backend.

Due to the way add_device() invariably adds to the master/slave device
lists, while keeping ClutterInputDevices 1:1 with device IDs, it may
leave invalid pointers in the list if add_device() is called multiple
times for the same device ID. There are two situations where this may
happen:
1) If devices are disabled and later enabled: devices are added invariably
to the master/slave lists on constructed(), but then on XIDeviceEnabled
they'd get added yet again.
2) Racy cases where the ClutterDeviceManager is created around the same time
XIHierarchyEvents are sent. When getting the XIDeviceInfo on constructed(),
these devices may already appear as enabled, even though XIDeviceEnabled
is seen through XIHierarchyEvents processed in the event loop sortly after.
This last case can be seen when starting gnome-shell on a different tty,
and entering in the one it's been spawned on, clutter initialization
happens around the same time devices are added back because of the tty
switch, and multiple extra ClutterInputDevices are created.

Currently we where checking whether the damage_history list contains
more or equal then buffer_age entries. This is wrong because we prepend
our current clip to the list just before the check.
Fix that to check whether we have more entries instead of more or equal.

The documentation for the s and l components is incorrect; these have to
be percentage values and must have a '%' character right after the
number.

The internal delete_text() implementation takes a start and an end
position, whereas the public delete_chars() method takes a number of
characters to delete starting from the current cursor position.
The :unscaled-font-dpi property is used to override the existing
:font-dpi value when running on high DPI density displays; since it's a
write-only property we don't need to have a separate storage, nor we
need to choose between :font-dpi and :unscaled-font-dpi depending on
whether or not either has been set. If we select which one to use
between :font-dpi and :unscaled-font-dpi when computing the font
resolution, we end up breaking the code that relies on changing
:font-dpi directly on a per-Settings basis.
Like we do for the windowing surfaces, we should have a run time knob
(in the form of an environment variable) to allow changing the scaling
factor of the font resolution.
We need to provide an escape hatch to ClutterCanvas so that it's
possible to override the window-scaling-factor ClutterSetting. This is
going to be useful in the future in case the user has better knowledge
of the window scaling factor that is going to be used with a specific
set of ClutterCanvas contents (e.g. on different outputs or stages).
https://bugzilla.gnome.org/show_bug.cgi?id=705915
ClutterCanvas is a ClutterContent interface implementation; this means
that it can be created and modified regardless of whether it is
associated to a specific actor or a stage. For this reason, we cannot
walk the hierarchy and get the window scaling factor for high DPI
density displays out of the ClutterStage when we create the Cairo
surface that we will use to draw the canvas contents on.
We can use ClutterSettings:window-scaling-factor instead, since it's
what each ClutterStage will use anyway.
This will get slightly more complicated when we support per-output
window scaling factors (like on Wayland), but that will require changes
in the entire settings architecture anyway.
https://bugzilla.gnome.org/show_bug.cgi?id=705915
If we get a change in the window scaling factor we want to resize the
backing store of each stage, so we use the notification on the
ClutterSettings:window-scaling-factor property to do so.
https://bugzilla.gnome.org/show_bug.cgi?id=705915
We want the settings object to handle setting and getting the
window scaling factor value, both through backend-specific settings and
through the CLUTTER_SCALE environment variable. This means turning the
ClutterSettings:window-scaling-factor property into a readwrite one,
instead of write-only, so that ClutterStage implementations will be able
to query the window scaling factor on construction.

We do some argument validation inside _clutter_stage_do_pick(), which is
the internal version of clutter_stage_get_actor_at_pos(), but we don't
do coordinate space validation, and instead we rely on call sites doing
the right thing.
We should, instead, remove the argument validation from the internal
function, which is pointless and against the coding practices, but do
coordinate space validation internally.

The current conformance test suite is suboptimal in many ways.
All tests are built into the same binary, which makes adding new tests,
builting tests, and running groups of tests much more awkward than it
needs to be. The first issue, especially, raises the bar of contribution
in a significant way, while the other two take their toll on the
maintainer. All of these changes were introduced back when we had both
Clutter and Cogl tests in tree, and because we were building the test
suite for every single change; since then, Cogl moved out of tree with
all its tests, and we build the conformance test suite only when running
the `check` make target.
This admittedly large-ish commit changes the way the conformance test
suite works, taking advantage of the changes in the GTest API and test
harness.
First of all, all tests are now built separately, using their own test
suite as defined by each separate file. All tests run under the TAP
harness provided by GTest and Automake, to gather a proper report using
the Test Anything Protocol without using the `gtester` harness and the
`gtester-report` script. We also use the Makefile rules provided by GLib
to vastly simplify the build environment for the conformance test suite.
On top of the changes for the build and harness, we also provide new API
for creating and running test suites for Clutter. The API is public,
because the test suite has to use it, but it's minimal and mostly
provides convenience wrappers around GTest that make writing test units
for Clutter easier.
This commit disables all tests in the conformance test suite, as well as
moving the data files outside of the tests/data directory; the next few
commits will re-establish the conformance test suite separately so we
can check that everything works in a reliable way.
When the threshold-trigger-edge property was introduced in
GestureAction, it was late in the cycle and I elected to keep it
private, given the fact that nobody was subclassing GestureAction
outside of Clutter itself.
These days, people are experimenting more with the GestureAction API, so
they will need access to the various knobs that control the class
default behaviour.

Use G_GNUC_INTERNAL instead of the leading underscore, as we may make
the accessor functions public at some point. Also, clean up the

Our clip coordinates are relative to the stage, not model-view
transformed. cogl_framebuffer_push_rectangle_clip() was accidentally
used instead of cogl_framebuffer_push_scissor_clip() when porting
to the framebuffer clip API.
