Summary:
So far we were following a bit unique and rare doxygen comment style:
/**
* Contents of the comment.
**/
Doxygen comments with this style look balanced and neat, but many people
that contribute to KWin don't follow this style. Instead, they prefer
more traditional doxygen comment style, i.e.
/**
* Contents of the comment.
*/
Reviewing such changes has been a bit frustrating for me (so selfish!)
and for other contributors.
This change switches doxygen comment style in KWin to a more traditional
style. The main reason for doing this is to make code review process easier
for new contributors as well us.

Summary:
Currently code base of kwin can be viewed as two pieces. One is very
ancient, and the other one is more modern, which uses new C++ features.
The main problem with the ancient code is that it was written before
C++11 era. So, no override or final keywords, lambdas, etc.
Quite recently, KDE compiler settings were changed to show a warning if
a virtual method has missing override keyword. As you might have already
guessed, this fired back at us because of that ancient code. We had
about 500 new compiler warnings.
A "solution" was proposed to that problem - disable -Wno-suggest-override
and the other similar warning for clang. It's hard to call a solution
because those warnings are disabled not only for the old code, but also
for new. This is not what we want!
The main argument for not actually fixing the problem was that git
history will be screwed as well because of human factor. While good git
history is a very important thing, we should not go crazy about it and
block every change that somehow alters git history. git blame allows to
specify starting revision for a reason.
The other argument (human factor) can be easily solved by using tools
such as clang-tidy. clang-tidy is a clang-based linter for C++. It can
be used for various things, e.g. fixing coding style(e.g. add missing
braces to if statements, readability-braces-around-statements check),
or in our case add missing override keywords.

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.

Summary:
The code ifdefed by ENABLE_TRANSIENCY_CHECK does no longer compile and
has not compiled since the switch to Qt 5 and KF5 as it still uses
kDebug and (worse) kDBacktrace. There are several other changes which
broke the code and I failed trying to get it to compile again. It's a
classic example of bitrot happening to code which is never getting
compiled.
As this has not been in a state which could compile for at least several
years, I think it's best to completely remove it.

Summary:
Thanks to std::bind we don't need that many different slots to setup the
global shortcut connections. Instead we can have one shared
implementation which takes the argument and passes it to the window.
To support std::bind arguments in kwinbindings the initShortcut method
and dependencies are adjusted as well as a new macro is added.
As I don't want to include abstract_client.h in workspace.h a new enum
is created for the quick tiling flags used in Workspace. This caused a
larger refactoring as the change to an enum class also caused quite some
changes.

Summary:
So far KWin only updated the x11 timestamp if the new timestamp is larger
than the existing one. While this is a useful thing it creates problems
when the 32 bit msec based time stamp wraps around which happens after
running an X server for 49 days. After the timestamp wrapped around KWin
would not update the timestamp any more and thus some calls might fail.
Most prominent victims are keyboard and pointer grab which fails as the
timestamp is either larger than the server timestamp or smaller than the
last grab timestamp.
Another problem related to timestamp handling is KWin getting broken by
wrong timestamps sent by applications. A prominent example is clusterssh
which used to send a timestamp as unix time which is larger than the
x timestamp and thus our timestamp gets too large.
This change addresses these problems by allowing to reset the timestamp.
This is only used from updateXTime (which is normally invoked before we
do things like grabKeyboard). Thus we make QX11Info::getTimestamp the
ultimate trusted source for timestamps.

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

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.

Similar to X11 world: we send a sync request on each size change and
block till we get the next damage with the proper size.
Testing seems to show a very smooth resize experience. We automatically
sync to the resize speed of the client.
Maybe we need a timeout in case the client isn't able to resize to the
requested size.
Uses Xcb::WindowAttributes and Xcb::WindowGeometry instead of XLib
variant. In addition it uses the XServerGrabber to ensure that the
xserver grab is removed in all code paths.
A new macro is added to utils.h to make the grabbing of XServer in
current context more obvious.
The Xcb::Property can wrap the xcb_get_property call and provides
convenient access methods to read the value of the reply with checks
applied. For this it provides a templated ::value method for reading a
single value or reading an array. There's also a ::toBool and
::toByteArray which performs the conversion directly with default values
for the type and format checks.
Xcb::TransientFor is changed to be derived from Property instead of
Wrapper directly, so that the reading of the property value can be
shared.
Xcb::StringProperty is a convenient wrapper derived from Property to
handle the reading of a string property providing a cast to QByteArray
operator. This replaces the ::getStringProperty from utils. Though the
separator functionality from ::getStringProperty is not provided as that
is only used in one function and handled there.
All the custom usages of xcb_get_property or getStringProperty are
replaced to use this new wrapper. That simplifies the code and ensures
that all properties are read in the same way.

Fixes the annoyances of having to mock it in the unit tests which include

REVIEW: 116900
Instead of passing the macro based Predicate to findClient it now
expects a function which can be passed to std::find_if.
Existing code like:
xcb_window_t window; // our test window
Client *c = findClient(WindowMatchPredicated(window));
becomes:
Client *c = findClient([window](const Client *c) {
return c->window() == window;
});
The advantage is that it is way more flexible and has the logic what
to check for directly with the code and not hidden in the macro
definition.
In addition there is a simplified overload for the very common case of
matching a window id against one of Client's windows. This overloaded
method takes a Predicate and the window id.
Above example becomes:
Client *c = findClient(Predicate::WindowMatch, w);
Existing code is migrated to use the simplified method taking
MatchPredicate and window id. The very few cases where a more complex
condition is tested the lambda function is used. As these are very
local tests only used in one function it's not worthwhile to add further
overloads to the findClient method in Workspace.
With this change all the Predicate macro definitions are removed from
utils.h as they are now completely unused.

Instead of passing the macro based Predicate to findUnmanaged it now
expects a function which can be passed to std::find_if.
Existing code like:
xcb_window_t window; // our test window
Unmanaged *u = findUnmanaged(WindowMatchPredicated(window));
becomes:
Unmanaged *u = findUnmanaged([window](const Unmanaged *u) {
return u->window() == window;
});
In addition an overload is added which takes the window id to cover
the common case to search for an Unmanaged by its ID. The above example
becomes:
Unmanaged *u = findUnmanaged(window);
The advantage is that it is way more flexible and has the logic what
to check for directly with the code and not hidden in the macro
definition.
As can be seen in [1] the patches to KWin were in CVS HEAD before the
protocol got standardized and it never got any adoption. It's neither in
the NETWM spec, nor implemented in Qt4 nor in Qt5. KWin did not even add
the protocol to the NET::Supported property.
Thus it doesn't make much sense to keep a protocol which nobody speaks.
Still the code around the protocol is kept and also the names are kept.
Only difference is that Client::takeActivity got removed and the code
moved to the only calling place in Workspace. Motivated by that change
the enum defined in utils.h is moved into Workspace, it's turned into
a proper QFlags class and used as a type in the method argument instead
of a generic long.
