Summary:
What happens:
* Activity switch calls invalidateFilter on TaskFilterProxyModel,
which may remove rows in response.
* Up the proxy chain, TasksModel may ask LauncherTasksModel to
emit dataChanged for its contents in response to the row removal,
to cause its own filtering to re-evaluate the launchers for the
life cycle logic.
* This can cause TFPM to do more filtering before invalidateFilter
has actually returned, causing trip-ups such as duplicated rows
in the proxy.
* Eventually the corrupted maps cause a memory corruption crash.
This patch changes step 2 to "find the launchers in the TFPM (the
direct source model) and ask for a dataChanged for each". This
costs us a loop and accesses to IsLauncher, but on the other hand
fixes the crash and avoids a lot of filtering and mapping work
between LTM and up to and including TFPM. It's also just better
code to ask for the dataChanged only from the model we need it
from.

Summary:
Alphabetical sorting currently compares a concatenation of
"AppName" (determined by heuristic) and Qt::DisplayRole (usually
the window title) using QString::localeAwareSort. This reflects
that the motivation behind alphabetical sorting is generally to
keep windows belonging to the same app grouped together and then
order those groups alphabetically.
The current code achieves this, but the particulars turn out to
negatively impact users of multi-windowed apps that frequently
change window titles in ways that impact sorting, particularly
tabbed web browsers. Switching between tabs may change the order
of browser windows on the Task Manager. Multiple instances of
feedback suggest this is jarring and unexpected, despite
technically being alphabetical.
This patch changes behavior as follows:
1. Instead of comparing "<App Name><DisplayRole>" it will try to only
compare "<App Name>", falling back to "<DisplayRole>" if the app
name can't be determined.
2. If two tasks compare to equal in the above, it will fall back to
source model row order, i.e. creation/append sorting.
This still achieves the primary goal laid out above while
keeping the sort order within an app "group" stable when using
alphabetical sorting.
BUG:373698
An alternative means to achive this behavior would be via existing
Task Manager settings. To wit:
1. Enable grouping
2. Disable group popups, so groups are instead maintained inline
on the widget
I'm actually considering suggesting the above (plus changing
sorting to Manual) as new default settings for 5.10 - but in
the meantime it still makes sense to tune the alphabetical
sorting mode in this way, and put the improved behavior into
5.8 and 5.9 to address user feedback earlier.

syncLaunchers() is called after drag operations end to write the order

source model. The per-activity launcher pinning work recently broke
this by changing the model that's looped over.

Summary:
Hitting again a bug where switching desktops shows a delay of several seconds
before the taskbar updates, I noticed that this code path was called 81
times in 7 seconds (!) for kmail (maybe because I start it from cmdline
rather than via a .desktop file).
After the 4 slow calls to KWindowSystem::icon it seems definitely worth
it to cache the result.
Overall the main performance bug is still there though, switching
desktops is still slow, but now all backtraces show QML triggered
by model/view dataChanged signals, no idea yet, other than hoping
for the pending QSFPM patches to help with this (no need to re-sort
when the dataChanged roles are unrelated to the roles used for sorting).

Versions of VirtualBox packaged on Neon and Fedora now have
a proper WM_CLASS:
Fedora: WM_CLASS(STRING) = "VirtualBox", "VirtualBox"
Neon: WM_CLASS(STRING) = "Qt-subapplication", "VirtualBox"
And install a matching virtualbox.desktop.
We can therefore drop this rule.

Side note: The rule should actually still have worked, but
for some reason KServiceTypeTrader refuses to match a .desktop
with 'Exec=VirtualBox %U' when we query for 'VirtualBox', as
extracted from cmdline. I'm talking to dfaure about it.

Summary:
It turns out that Chrome under certain conditions will change its
window metadata as it quits, causing a race we sometimes lose, failing
to reveal the associated launcher because we can no longer match it
to the window at window closing time. Instead we are now forced to
re-check all launchers after the window is gone. As a speed optimi-
zation we only consider top-level windows (and startups) as being in
a group implies matching siblings.
In addition this refactoring eliminates a use of Qt::QueuedConnection
that allowed for an unpredictable event loop spin inbetween things.

Summary:
This makes the AdditionalRoles enum available to Qt Quick. Useful for
calling data() TasksModel from inside QML, which uses AbstractTasksModel
roles but doesn't actually inherit from AbstractTasksModel.
The reason TasksModel doesn't inherit from AbstractTasksModel is
because it inherits from QSortFilterProxyModel, and it doesn't fly
to multiple-inherit from two QObject-derived classes. This is also
why AdditionalRoles can't be moved to AbstractTasksModelIface easily.
The VDG is working on tooltip changes that require this.

culimating in TasksModel needs to be re-executed, as it compares

Mapping the trigger conditions to affected rows is deliberately

Summary:
This adds a new data role "ChildCount" to AbstractTasksModel and
implements it in TaskGroupingProxyModel.
The purpose of this data role is as a means of signalling to a Qt
Quick delegate for a top-level row that a property of the item -
namely the number of children it has - has changed. Qt Quick's poor
support for tree models makes the existing way of signaling this
(rowsInserted) prohibitive to use.
The Task Manager applet needs this info because it's in charge of
telling the window manager about the screen coordinates of window
delegates (through support code in this library). When a window is
directly added to an existing group, there is no new delegate
created, nor does the existing delegate change position. An
increase of ChildCount will be used in this case to decide to
publish delegate geo for the new window.

Summary:
This adds support for app ids which are absolute paths to .desktop
files to WaylandTasksModel, matching the heuristic in XWindowsTasksModel.
Behavior between the two models is made more similar in various ways,
such as matching codepaths for generating the ids inserted into the
KActivities database in requestNewInstance/requestOpenUrls (also the
X11 model was missing the notifyAccessed calls) and producing launcher
URLs.
Icons are still left to KWin however, instead of reading them from
KService (which is what KWin does in any case on Wayland) or from the
.desktop file. The latter might make sense, but to avoid duplicated
code would then best be done in KWin.

Summary:
Utility windows (NET::Utility/_NET_WM_WINDOW_TYPE_UTILITY) should
not be on the Task Manager, but they should be on the Pager. This
patch achieves this by evaluating the window type in the
AbstractTasksModel::SkipTaskBar data role.
I considered the alternative approach of making a new
AbstractTasksModel::IsUtilityWindow (or similar) data role and
adding a pass to evaluate it to TaskFilterProxyModel, then
configuring the filter models in TasksModel and the Pager backend
differently. But this is not very extensible. Then I realized that
AbstractTasksModel data roles do not and should not reflect X11
idioms anyway; the point of the library is to abstract for the
purpose of UI, and what XWindowTasksModel considers "SkipTaskBar"
is really an implementation detail. This makes all the more sense
considering on Wayland we have no notion of window types (beyond
"popup") yet, and don't quite now how it's going to evolve.
Various API docstrings have been changed to better reflect that
the meaning of the data role doesn't map to anything specific in
the tasks.

Tasks which demand attention usually bypass the filters by activity
and desktop, i.e. the Task Manager will show a window that's
demanding attention even when filtering is enabled and we're on a
different activity or desktop.
This behavior is however not suitable for the Pager, which shouldn't
show windows demanding attention on all workspace delegates. This
patch adds a prop that allows the Pager to disable the filter bypass.
