38e22ce6d1 [platforms/x11] Properly unload effects on X11
Summary:
When Compositor finishes compositing, it destroys EffectsHandlerImpl,
which in its turn tries to unload all effects. But there is a problem...

EffectsHandlerImpl has platform-specific hooks to ungrab keyboard and
also stop mouse interception. Given that any call made to a virtual function
in the destructor of a base class(EffectsHandlerImpl) won't go to a derived
class(EffectsHandlerImplX11), keyboard won't be ungrabbed even if effect
that grabbed it is already gone.

7b20e1f66f Overhaul doxygen comments
Summary:
We have a mix of different doxygen comment styles, e.g.

    /*!
      Foo bar.
     */

    /**
     * Foo bar.
     */

    /** Foo bar.
     */

    /**
     * Foo bar.
     */

    /**
     * Foo bar.
     **/

To make the code more consistent, this change updates the style of all
doxygen comments to the last one.

Test Plan: Compiles.

5d63b9c05b Fix flickering with Qt 5.12
Summary:
Mesa requires XESetWireToEvent xlib callbacks to be called
when DRI2 is used. This is done by the GLX integration in
the Qt's xcb plugin, but Qt 5.12 initializes the GLX integration
only when required, e.g. when a window with OpenGL support is
created or when availability of OpenGL is checked.

So force initialization of the GLX integration by calling
QOpenGLContext::supportsThreadedOpenGL().

5b4eb80c8f Set specific edge cursor shape when resizing
Summary:
Instead of seeing the cursor <--> on the left edge you now see an icon
that looks like |<-  .

This brings kwin decorations in line with GTK CSD icons.

In theory this is also useful to tell which window will resize in the
case of side-by-side windows (regardless of whether borders are on or
not). In practice with the adwaita icon theme I tested with it's not
very intuitive to realise which is which till you learn the icon.

Change is more involved than it should be as Qt::CursorShape doesn't
have these entries, and I don't want to shadow that enum internally or
have
to change kwin effect code.

Specifics depend on cursor icon theme if they are not present it will
fallback to the <--> icon. (Breeze does not have them currently)

Test Plan:
Resized some windows (on X and on Wayland)
Correct icon appeared on Adwaita
Existing icon appeared on Breeze

ea5e701164 [x11] Fix interactive point selection
Summary:
The support for interactive point selection was missing. This results in
the ColorPicker dbus API always returning an error on X11. We either need
to disable the ColorPicker on X11 or add support for this functionality.

As the X11 platform basically supports selecting a point in the
interactive window selection it makes more sense to add this missing
method in the platform than to disable support of color picker effect.

BUG: 387720
FIXED-IN: 5.12.1

Test Plan:
Run KWin/X11 on Xephyr and was able to pick a color and
kill a window

a7117e4304 Don't use the global KConfig object on the OpenGL freeze detection thread
Summary:
This is meant to address Bug 372114. The problem here is that the KConfig
object (and its derivatives), that the freeze detection thread needs to
record the freeze, are not thread safe. When it happens that the main
thread is in fact not frozen, it is possible that the two stomp on each
other's KConfig object.

The solution applied here is to use the KSharedConfig::openConfig
function, which is thread safe, on the freeze detection thread. As was
mentioned by Martin Flöser in the discussion, the thread needs to obey
the name of the main config file of KWin, which can change in the future.

As a secondary issue, this patch also turns off KCrash reporting for
aborts due to a freeze being detected. IMO it is not very user friendly
to still show a crash report to the user, even after this bug is fixed,
for the deliberate SIGABRT. Maybe a less intrusive notification could be
used to tell the user why effects are suddenly disabled?

I've been using kwin with this change for several weeks now and it makes
the restarts of kwin due to freezes unobtrusive. However, most (I would
say almost all) of these freezes are actually instances where the system
 is being slow after eg. screen resolution is changed.

2e868c50df Create a dedicated X11Filter for Client sync events and move it to X11 platform
Summary:
On Wayland we have the sync disabled as it doesn't work properly. This
allows us to also move the sync event handling into the X11 standalone
platform.

The code is slightly refactored: instead of passing the event to each
Client, we search for the matching Client. For that the SyncAlaram struct
is added to public section of Client. The method to handle the sync
doesn't need the event any more and is moved from events.cpp to
client.cpp.

Test Plan:
Run Xephyr+kwin_x11, resized a window and verified through
gdb breakpoint that the sync still works

09489a4c2b Add a pure virtual method to Platform to describe the supported compositors
Summary:
So far KWin does not know which Compositors the platform actually
supports. This results in KWin happily trying to use the OpenGL
compositor on fbdev or the QPainter compositor on hwcomposer although
that is obviously going to fail as the platform doesn't support this.

By adding a pure virtual method all Platforms can define what they
support. In a later step the Compositor can use this to create an
appropriate scene and also perform proper fallback handling in case the
scene creation fails.

7ef8409157 Move X11-only specific part of EffectsHandlerImpl to x11 platform plugin
Summary:
The Platform API is extended by a call to create the EffectsHandler. In
X11 standalone Platform a new EffectsHandlerImplX11 is added which
contains the X11 only parts of the EffectsHandler, such as grabbing the
X keyboard and the X11 mouse interception window.

The EffectsHandlerImpl gains some virtual methods for the parts which
are now done in the X11 specific implementation. In return we get rid of
lots of if-else structures checking for the operation mode.

Test Plan: Only compile tested.

8ae37c420b Move SceneOpenGL into a dedicated plugin
Summary:
Unfortunately a rather large change which required more refactoring than
initially expected. The main problem was that some parts needed to go
into platformsupport so that the platform plugins can link them. Due to
the rather monolithic nature of scene_opengl.h a few changes were
required:
* SceneOpenGL::Texture -> SceneOpenGLTexture
* SceneOpenGL::TexturePrivate -> SceneOpenGLTexturePrivate
* texture based code into dedicated files
* SwapProfiler code into dedicated files
* SwapProfiler only used in x11 variants
* Safety checks for OpenGL scene moved into the new plugin
* signal declared in SceneOpenGL moved to Scene, so that we don't need
to include SceneOpenGL in composite

The code in events.cpp was problematic as it was called in a Wayland

1cc38c929a Move updateXTime into the X11 standalone platform
Summary:
KWin::updateXTime only delegates into the platform API where the method
is a no-op. The actual implementation is moved into the X11 standalone
platform as it uses QX11Info which is non functional except on the X11
standalone platform.

This change exposes a problem with timestamp handling: on Wayland the
X11 timestamp does not get updated at all, causing e.g. window sync not
work correctly (c.f. bug 374881). We cannot implement the updating in the
same way as QX11Info/Qt xcb platform does it as that would introduce a
blocking roundtrip to XWayland which is dangerous.

As a side-effect this change removes linking to Qt5::X11Extras in kwin
core as it's no longer needed.

b4a79d30e6 Move the X11 specific OverlayWindow into the platform/x11
Summary:
The overlay window is only needed for the X11 based compositors. Given
that it is better suited in the X11 platform. Unfortunately it is not
possible to completely move it into the platform plugin as it is still
referenced in KWin core (e.g. SceneXRender). Due to that the
OverlayWindow in KWin core is turned into a pure virtual class with the
implementation being moved into the plugin.

The platform API gains a new virtual factory method which is only
implemented in the X11 platform.

ea5d611de1 Require C++14
Summary:
KWin already used C++14 constructs in a conditional way. This doesn't
make much sense today, it's better to just require C++14.

For KWin only gcc and clang are currently compilers of relevance. Gcc
supports C++14 since version 5 and defaults to C++14 since 6.1 [1].
Clang supports C++14 since version 3.4 [2].

An overview of compiler support in various distributions:
* Debian stable (stretch): gcc 6.3, clang 3.8
* Debian oldstable (jessie): 4.9, clang 3.5
* Ubuntu 17.04: gcc 6.1, clang 3.8
* Ubuntu 16.04: gcc 5.3, clang 3.8
* openSUSE Tumbleweed: gcc 7.1, clang 4.0
* openSUSE Leap 42.3: gcc ?, clang ? [3]
* FreeBSD: clang >= 34 in ports
* Slackware 14.2: gcc 5.3

06a558e3de [platforms/x11] Quit the OpenGL Freeze protection thread on shutdown
Summary:
Weird NVIDIA behavior fixup part 2. Now that we do no longer freeze when
NVIDIA decides to create an OpenGL error on startup
(aefb5f4dd9), we experience a new issue.
KWin is terminating (no idea why, [1]) and at the same time the OpenGL freeze
protection thread is still running. So far we did not terminate the
thread on shutdown and thus we hit an abort in Qt.

This change ensures that we properly terminate the thread on shutdown.

[1] My current theory is that games terminate KWin, common pattern of
bug reports is "steam".

BUG: 382283
FIXED-IN: 5.10.4

Test Plan:
Tortured KWin by making sure I go through the code path,
saw the abort without the patch, no more abort with the patch

4e9456a857 [platforms/x11] Fix incorrect screen edge approaching with switch desktop on window move
Summary:
There is a regression in WindowBasedEdge::soStopApproaching. Due to
only operate when the edge activates for pointer it is possible that
the cursor polling stays active. Explaining the situation:

1. Activate switch desktop when moving window
2. Start moving a window
3. Move mouse into the approach geometry
-> doStartApproaching activates as we are moving a window
4. stop moving window
-> doStopApproaching early exits as the position does not activate for
   pointer any more - we are not moving a window
-> cursor polling is still connected and whenever mouse enters edge
   approaching is started

The analysis shows that the check whether activates for pointer is wrong
in the case of stop approaching. If the edge started to approach, we also
need to stop approaching.

This change addresses the problem by turning the check into whether the
connection for cursor position update is set.

This is the third bug fix to the X11 screen edge handling after
introducing touch screen edges. This needs more manual testing by
everybody in the Plasma team who is still using X11.

014afe1c05 [platformx/x11] Fix touch events for internal Qt windows
Summary:
To have touch events working we need to do memory layout changes on the
xcb events. This is fine for identifying the touch events which should
trigger the screen edge. But when passed on to Qt to have QtQuick windows
(e.g. Alt+Tab) handle the touch events, this results in a problem:
Qt itself does also the memory movement and then the movement is double
and touch events break.

To prevent this problem an RAII class is added which moves the memory in
the ctor and moves it back in the dtor. So during KWin's processing it
has the right memory layout and later on in Qt's processing it has the
proper "wrong" layout which Qt can fix again.

Test Plan: Touch events in Alt+Tab work

eec6afe6f5 Don't map screenedge approach window if edge is only used for touch
Summary:
Another regression from enabling touch support on X11.
The approach window for pointer input gets unmapped as soon as the mouse
enters the window. This ensures that mouse motion events are not stolen
from other applications. But with the touch events we did not even react
on the enter event if it's not activated for pointer. The result was an
area around the screenedge being blocked for pointer input.

This change only creates and maps the approach window if the edge is
activated for pointer input.

aa6c8f8116 Add support for activating screenedges through touch swipe gestures
Summary:
Each Edge creates a SwipeGesture for touch activation. The swipe needs to
be a single finger starting from the edge into the screen for at least
20 %. The SwipeGesture and GestureRecognizer is extended to support the
use cases of the touch screen edge swipe.

New features supported by the gesture system are:
 * minimum and maximum position
 * a minimum delta for the swipe
 * progress signal based on the minimum delta
 * starting a swipe with a start point

The Edge has the progress signal connected to its approach signal, thus
visual feedback is provided through the screen edge effect.

The screen edge system supports touch only for the edges (corners are
too difficult to activate on touch screens). At the moment the following
features are supported:
 * screen edge show/raise of windows (e.g. auto hidden panels)
 * trigger the configured action
 * trigger the configured callback function (e.g. script)

In future it might make sense to add a touch specific configuration
action to support different actions for screen edges activated by mouse
and touch.

BUG: 370323

Test Plan:
configured a screen edge and triggered through touch,
added an auto-hiding panel and triggered through touch

65ddd32d1a Split modifier only handling into a dedicated InputEventSpy
Summary:
The functionality regarding triggering modifier only shortcuts is moved
out of Xkb - where it doesn't belong to - and is turned into an input
event spy listening for the changes it is interested in. Previously
the state got queried by asking e.g. for the pressed buttons, now it's
tracked directly.

The X11 side needs a larger change due to that as now pushing the events
into Xkb does not trigger modifier only shortcuts any more. Instead the
"normal" way through the platform API needs to be used which triggers the
processing of filters and spies.

The problem here is that our redirections only process events if they are
inited and that only happens on Wayland. We cannot call init on them as
that would create all the Wayland filters and spies and processing would
probably break. As an intermediate solution the spies are now processed
and there we know that it won't matter. A future solution would be to
remove the init checks completely and just send through both filters and
spies and ensure that on X11 only the supported ones are loaded.

7b464cf284 Support interactive window selection through the Platform
Summary:
A new virtual method is added to Platform:
startInteractiveWindowSelection

The interactive window selection enters a mode where the user can select
a window through the pointer or keyboard device. The cursor is turned
into a crosshair cursor, unless another cursor name is provided (e.g.
pirate for kill window).

Once a window is selected the provided callback method is invoked with
the selected Toplevel as argument. In case the user cancelled the
selection a nullptr argument is passed in.

Currently it's only implemented by the X11 standalone platform using the
logic from KillWindow. Just instead of killing the window the callback
is invoked.

KillWindow loses the X11 implementation and interacts with the new
functionality in Platform by providing a lambda function for the
killing.

Test Plan: Killing of X11 windows is still possible

Summary:
And finally nothing inside libkwineffects, libkwinglutils,
libkwinxrenderutils and kwineffect and kwin core uses KWin::display.
We are finally XLib free!

This change drops KWin::display and removes the include to QX11Info from
kwinglobals.h. And the libraries no longer need to link X11Extras.  Due
to that removal a few seeming unrelated changes are required to add the
include where needed and linkage to X11Extras.

The biggest change is to x11 platform plugin which still needs the
display and caches it in the Platform and passes it to various places in
a way that the code doesn't need to be adjusted.

d7fa827644 Pass function ptr to resolve glFunctions to initGL
Summary:
KWin still resolves some OpenGL function pointers. For that it needs to
use either eglGetProcAddress or glxGetProcAddress. With other words the
method to resolve needs to know whether it is egl or glx and needs both
a dependency to egl and glx. Especially the dependency to glx is ugly as
that pulls in XLib into our library.

The way so far was to pass an enum value to the initGL method to know
whether it's EGL or GLX. With this change the enum value is removed and
replaced by a function pointer to resolve the methods.

This simplifies the resolve code and allows to completely remove the glx
variant we still had in the library. Thus kwinglutils library is now glx
and XLib free.

Test Plan: nested KWin with OpenGL/EGL still works

e90e596864 Add way to hide/show cursor in Platform
Summary:
Some platforms support to hide and show the cursor. This will be needed
by e.g. the zoom effect which currently only provides this functionality
on X11.

This change introduces a new method in the Platform to hide and show the
cursor. The methods need to be called balanced and the implementation
takes care of only showing again if all hide got matched by a show.

The actual hiding and showing is performed in the platform plugins. So
far the DRM and X11/Standalone platforms implement the required
functionality, though other platforms probably could implement as well.

19147f5f85 [platformx/x11] Add a freeze protection against OpenGL
Summary:
With nouveau driver it can happen that KWin gets frozen when first trying
to render with OpenGL. This results in a freeze of the complete desktop
as the compositor is non functional.

Our OpenGL breakage detection is only able to detect crashes, but not
freezes. This change improves it by also added a freeze protection.

In the PreInit stage a thread is started with a QTimer of 15 sec. If the
timer fires, qFatal is triggered to terminate KWin. This can only happen
if the creation of the OpenGL compositor takes longer than said 15 sec.

In the PostInit stage the timer gets deleted and the thread stopeed
again.

Thus if a freeze is detected the OpenGL unsafe protection is written into
the config. KWin aborts and gets restarted by DrKonqui. The new KWin
instance will no longer try to activate the freezing OpenGL as the
protection is set.

If KWin doesn't freeze the protection is removed from the config as
we are used to.

Check for freezes for the first n frames, not just the first

This patch changes the freeze detection code to detect freezes in the
first 30 frames (by default, users can change that with the
KWIN_MAX_FRAMES_TESTED environment variable). This detects
successfully the freezes associated to nouveau drivers

ea52ef9e57 Add a PlatformCursorImage to Platform and EffectsHandler
Summary:
There are several effects (screenshot, zoom) which need access to the
cursor image and cursor hotspot. So far these effects used X11
unconditionally to get the cursor which obviously does not work on
Wayland.

This change adds a new class PlatformCursorImage to kwinglobals which
wraps what a cursor is (image and hotspot) and adds a new virtual method
to Platform to provide such a PlatformCursorImage. By default it's the
cursor image the Platform tracks. On X11/standalone platform this new
virtual method is overriden and provides a PlatformCursorImage from X11
using the code previously used in screenshot effect.

Screenshot effect and zoom are adjusted to use the new API instead of
X11.

Test Plan:
Zoom effect tested on Wayland, now gets the proper cursor icon.
X11 functionality not yet tested.

66d1a0cc7a Add event filter for key press/release events while KWin grabbed keyboard on root window
Summary:
The modifier-only-shortcuts break as soon as KWin grabs the keyboard
(e.g. alt+tab, present windows, etc.). The investigation shows that in
that case KWin does not get any raw key events any more and thus gets
confused about the state of the hold modifiers. E.g. alt+tab has the
alt key pressed, but we miss the release as the keyboard is grabbed.

This change addresses the problem by installing an additional event
filter for key press and release event which only filters for key events
on the root window. That way we can be sure that it only operates when
KWin grabbed the keyboard on the root window.

Note: the problem only exists when grabbing on the root window. If the
grab is on another window (e.g. moving a window) we still do get all
events.

The problem also seems to not happen if another application grabbed
keys on the root window. E.g. for key combinations grabbed by
kglobalaccel the correct sequence of key press/release as raw events
are reported. Also while the screen is locked the evemts are reported
and kscreenlocker grabs the keyboard on the root window.

Test Plan:
Used Alt+Tab and Present Windows and tried to activate launcher
afterwards.

9c5f972c6a Forward x11 raw pointer buttons to PointerInputRedirection
Summary:
The raw pointer button events intercepted in the XInput2 input filter
get sent through the Platform to the PointerInputRedirection. This
makes the PointerInputRedirection track the pointer button state and
emit the signals for button changed and axis changed.

These signals are used by the modifier-only shortcut detection to
determine whether the shortcut should trigger.

On X11 the "normal" input handling doesn't use the InputRedirection
and the emitted signals are not consumed by anything else. As
PointerInputRedirection is not inited the events are not forwarded
to the input filter, thus won't be processed by other parts and
won't interfere with the normal event processing on X11.

Given that it also doesn't matter that the input filter does not
apply the left-handed setting. The internal tracking will have a
wrong mouse button, but nothing is going to do decisions based on
the value of the pressed mouse button. For the moment all we are
interested in is that a button is pressed.

Test Plan:
Pressed meta, clicked, scrolled, released meta: launcher
did not open. Pressed meta, released meta: launcher opened

2a8ab547e1 Move X11Cursor into the x11standalone platform plugin
At the same time the xinput2 integration is split out of X11Cursor
and made a standalone part of the platform plugin. XInput integration
is nowadays not only used by the cursor position polling, but also
for modifier only shortcuts.

By splitting it out the modifier shortcuts start to work also when
one doesn't have anything requesting a mouse position polling.

This also simplifies the conditional builds: xinput integration is
only included if we have support for it at compile time without having
to have many ifdefs in the cursor implementation. For the inclusion of
cursor in the kcmkwin this also removes all the ifdefs.

The key events are only requested if we have xinput 2.1. Otherwise we
would not get all raw events if the input device gets grabbed.

03700500be Create Cursor instance through Platform
By default the InputRedirectionCursor is created and only the X11
standalone platform creates the X11 specific cursor.

This is a preparation step for moving the X11 specific cursor
implementation into the x11standalone platform plugin.
