The main advantage of SPDX license identifiers over the traditional
license headers is that it's more difficult to overlook inappropriate
licenses for kwin, for example GPL 3. We also don't have to copy a
lot of boilerplate text.
In order to create this change, I ran licensedigger -r -c from the
toplevel source directory.
Summary:
Qt has its own thing where a type might also have corresponding list
alias, e.g. QObject and QObjectList, QWidget and QWidgetList. I don't
know why Qt does that, maybe for some historical reasons, but what
matters is that we copy this pattern here in KWin. While this pattern
might be useful with some long list types, for example
QList<QWeakPointer<TabBoxClient>> TabBoxClientList
in general, it causes more harm than good. For example, we've got two
new client types, do we need corresponding list typedefs for them? If
no, why do we have ClientList and so on?
Another problem with these typedefs is that you need to include utils.h
header in order to use them. A better way to handle such things is to
just forward declare a client class (if that's possible) and use it
directly with QList or QVector. This way translation units don't get
"bloated" with utils.h stuff for no apparent reason.
So, in order to make code more consistent and easier to follow, this
change drops some of our custom typedefs. Namely ConstClientList,
ClientList, DeletedList, UnmanagedList, ToplevelList, and GroupList.

Summary:
Currently each managed X11 client is represented with an instance of
Client class, however the name of that class is very generic and the
only reason why it's called that way is because historically kwin
was created as an x11 window manager, so "Client" was a sensible choice.
With introduction of wayland support, things had changed and therefore
Client needs to be renamed to X11Client in order to better reflect what
that class stands for.
Renaming of Client to X11Client was agreed upon during the last KWin
sprint.
Test Plan: Compiles, the test suite is still green.

Summary:
Because KWin is a very old project, we use three kinds of null pointer
literals: 0, NULL, and nullptr. Since C++11, it's recommended to use
nullptr keyword.
This change converts all usages of 0 and NULL literal to nullptr. Even
though it breaks git history, we need to do it in order to have consistent
code as well to ease code reviews (it's very tempting for some people to
add unrelated changes to their patches, e.g. converting NULL to nullptr).
Test Plan: Compiles.

Summary:
Switch to Q_ASSERT in order to make code a bit more consistent. We have
places where both assert and Q_ASSERT are used next to each other. Also,
distributions like Ubuntu don't strip away assert(), let's hope that
things are a bit different with Q_ASSERT.

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:
The default implementations just return false/nullptr. The advantage of
having this in AbstractClient is that we can reduce the needed casts
from AbstractClient to Client in core as can be seen in this change.
There are more cases which can be improved thanks to this refactoring
which will follow in dedicated commits.

According to callgrind, checking kwin in release with debug symbols,
22% of cpu time in the method hasTransientInternal is spent doing
a cast to Client *, while at the begining of the method, the cast to
const Client * only uses 1.0x%.

Summary:
Commit 5d9027b110 introduced a regression in TabBox by using the generic
framework inside KWin to test for same application. What I did not
consider was that the code in TabBox was "broken by design". It didn't
use the generic check as that is too strict and considers windows from
different processes as not belonging to the same application. But this
is not wanted in the case of TabBox.
On the other hand the change itself is an improvement to also support
Wayland in a better way and not have special handling situations. Thus
just reverting would not help.
Instead this change addresses the problem by extending the internal API
and to allow more adjustements. So far there was already an
"active_hack" boolean flag. This is extended to proper flags with an
additional flag to allow cross application checks.
The checks in Client which would filter out different applications check
for this flag and are skipped if set. In addition ShellClient also adds
support for this flag and compares for the desktop file name.
Thus we get in TabBox the same behavior as before with the advantage of
having a better shared code base working on both X11 and Wayland.

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.

AbstractClient::mainClients is virtual and overriden in Client,
allMainClients has only a common implementation in AbstractClient.
In activation.cpp we still need one case where a temporary ClientList
needs to be constructed. Once transients are fully migrated that should
be removable again.
The change is mostly straight forward. Effects are straight forward
adjusted. Client::findModal is moved up, this causes still a few
dynamic_casts to Client. Mostly because Workspace::activateClient still
operates on Client.
Reduces number of possible roundtrips by fetching the NETWinInfo for
the leader_wid once and passing it to KWindowSystem::icon. This way
the NETWinInfo can be shared for all sizes instead of having
KWindowSystem::icon create a new instance with roundtrips for each
size.

We are only using the UrgencyHint, InputHint and GroupLeader from
WMHints. Those are provided by NETWinInfo, so we can use the
functionality provided by NETWinInfo instead of calling XGetWMHints.

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.

Client used to have dedicated methods for different icon sizes instead
of combining all pixmaps into one QIcon. This resulted in various parts
of KWin having different access to the icons:
* effects only got one pixmap of size 32x32
* decorations only got the 16x16 and 32x32 pixmaps combined into a QIcon
* tabbox could request all icon sizes, but only as pixmap
Now all sizes are available in one QIcon allowing to easily access the
best fitting icon in a given UI.
* "" needs to be wrapped in QStringLiteral
* QString::fromUtf8 needed for const char* and QByteArray
* QByteArray::constData() needed to get to the const char*
This dependency is causing build problems on a number of systems,
and it doesn't make much sense to bring in a whole library for three
one-line convenience functions.
The type of the transient_for related variables are changed to
xcb_window_t. They cannot be Xcb::Window as we don't take ownership over
the transient for window.
Variables are renamed to m_camelCase to follow naming scheme.
A wrapper for retrieving the TransientFor hint is added to the Xcb
Wrappers.
