96496a8608 Add a new markdown README
Summary:
The old readme was targetted at application developers having
conceptional questions about window management. While we all know that
this is very often needed, I doubt that any application developer is
looking at KWin's README to figure out why their window doesn't get
focus.

The new README is focussing more on potential new contributors by
describing what KWin is and how to reach our team. E.g as a nice small
document readable on git project hosting sides.

The information in the readme is mostly taken from
https://community.kde.org/KWin/Mission_Statement

Summary:
There's nothing relevant in kdeglobals and loading it can lead to noise
when deleting groups that override a system default.

We still cascade which will allow kiosk keys to work as well as relevant

9993c6d674 Add a dbus method getWindowInfo returning same data as queryWindowInfo
Summary:
This dbus method is intended to be used by the kwin rules dialog. KWin
can pass the internal id to the rules dialog through a command line
argument (or similar way) and the dialog can query the information
through the dbus call for the provided id. Thus it's possible to
implement one way to query the information which works on both X11 and
Wayland without any windowing system specific functionality.

Test Plan: See new added integration test

c20be6e0f1 Introduce a new HACKING.md document to replace the previous HACKING
Summary:
This document describes my own practices on how I develop and work on
KWin. Since we have nested KWin/Wayland my ways of developing completely
changed. Especially since it's possible to run without installing. Due
to that I thought it's a good idea to document how one can easily build
and run KWin.

Why a new document in the source tree instead of the wiki?

The main reason for using a wiki was that it allows to format, to link,
etc. This was prior to markdown and prior to code hosting places like
github or phabricator rendering the markdown pages. Given that I think
the information belongs in the repository and not in an external wiki.

Why not fix the existing page?

Our documentation on the wiki is quite outdated:
 * Qt 4 based
 * only X11
 * reviewboard
 * information about file structure which does not match reality

Especially the last point is where I think we need to do a clean cut and
just drop such information. Documentation about code belongs in the code
and not detached in wiki. It will outdate.

How to prevent this document will not become outdated?

Of course difficult. But I tried to not describe anything which might
change, such as file layout, etc.

28a52b2fd9 Drop the COMPLIANCE file
Summary:
This file has not been tracked for years. Nobody added when new features
were added, when existing code was broken, etc. E.g. none of the changes
since EWMH 1.4 is listed, none of the kde specific extensions is listed.

The document does not contain anything about Wayland protocol support.

I would not trust this document at all to say whether KWin is compliant,
but would check the source code. And after all most of the compliance is
done in KWindowSystem and KWayland, not in KWin.

Also the document lists compliance of other non-KWin elements such as
Qt, kicker (kde 3 thing, not application launcher), etc. This shows it's
also something which doesn't belong in KWin's source tree.

This change removes a small difference between X11 and Wayland clients.
It ensures that all transients are sent to the same desktop as the main

general it already worked. This is just a special case for
sendClientToDesktop which supports sending to the same desktop so that
all transients are sent to that desktop.

Summary:
When launching the touchpad kcm we see the following warning:

And the Gui shows "Error while loading values. See logs for more
information. Please restart this configuration module".

By extending the unit test for reading back the properties through DBus
I noticed that it's not trivially possible to export QFlags to DBus. As
the QFlags can be implicitly casted to int, the property is changed to
an int value.

a0b482cbab Introduce a command line option to disable any kind of global shortcuts
Summary:
This command line option is useful for KWin in embedded use case. That
is when KWin is just used as a compositor for one application instead of
a complete desktop environment. In such a setup global shortcuts are not
wanted and interfere with the application. E.g. one does not want Alt+F4
to close the window, that would render the system unusable.

This change introduces a command line option and disables the following
event filters and spies:
 * global shortcuts
 * modifier only shortcuts
 * terminate session
 * virtual terminal switching
 * screen edges

KGlobalAccel still gets inited, otherwise the (non-functional) binary
would be launched when KWin registers it's global shortcuts.

Test Plan:
New test added based on existing tests for the global
shortcuts, ctest passes

90a26e2e8d Try to invalidate quad cache when shadow is changed
Summary:
213239a0ea tried to address the case when
a wayland client gets shadow after it was mapped, but because of poor
testing from my side, another bug was introduced. If a decoration tooltip
or the user actions popup is shown, then in some cases it can be blank.

Usually, SurfaceInterface::shadowChanged proceeds SurfaceInterface::sizeChanged,
so when the shadow is installed, window quads cache is rebuilt. But
because shell client already knows the geometry of the internal client,
goemetryShapeChanged is not emitted, thus the cache is not updated.

It would be better just to invalidate the cache when the shadow is
installed, uninstalled, or updated. This reduces the number of
unnecessary invocations of Scene::Window::buildQuads and also moves
handling of the window quads cache away from the Shadow class.

BUG: 399490
FIXED-IN: 5.15.0

eab71a8a19 Privatize variables in InputDeviceHandler
Summary:
Some members were declared protected. Better style is to have them private
with public or protected getters and setters.

This also removes the unnecessary m_input variable.

Test Plan: Builds and runs.

b5a91cdfe0 Float position values in drag input filter
Summary:
We lost information when using QMouseEvent::globalPos, since
it is integer. Use instead InputRedirection::globalPointer,
which is updated before the filters are processed and is
float.

Test Plan: Manually.

295138145c Make sure that effect windows outlive effects
Summary:
Compositing is suspended/finished in a very hard way fashion, effect
windows are destroyed without notifying effects about it.

AnimationEffect tries gracefully release deleted windows, but because
in some cases(like when suspending compositing) a deleted window can
be already destroyed, a segmentation fault can happen.

This change adjusts the order in which effect windows and effects are
destroyed, so AnimationEffect (and other effects) cannot access dangling
pointers.

BUG: 400788
FIXED-IN: 5.15.0

3ad5604580 [scenes/opengl] Cleanup cached decoration shadow textures when suspending compositing
Summary:
When suspending compositing, SceneOpenGLShadow cannot cleanup cached
decoration shadow textures because the effects handler is already gone.

This sometimes can result in a crash when running kwin_x11 --replace
(we're hitting an assert statement).

To fix that, let's use the scene instead of the effects handler for
making the OpenGL context current.

Test Plan:
No longer hit the assert statement:

    ASSERT: "m_cache.isEmpty()" in file /home/vlad/Workspace/KDE/src/kde/workspace/kwin/plugins/scenes/opengl/scene_opengl.cpp, line 2025
    Application::crashHandler() called with signal 6; recent crashes: 1
    QCoreApplication::applicationFilePath: Please instantiate the QApplication object first
    KCrash: crashing... crashRecursionCounter = 2
    KCrash: Application Name = kwin_x11 path = /home/vlad/Workspace/KDE/usr/bin pid = 5407
    KCrash: Arguments: /home/vlad/Workspace/KDE/usr/bin/kwin_x11 --replace
