Summary:
This introduces a TryIgnoreRuntimes key in taskmanagerrulesrc's Settings
group that can be used to list known runtime executables that can be
ignored when trying to identify the application owning a window by the
command line of the associated process.
A concrete example is the Frozen Bubble application. Frozen Bubble
installs a frozen-bubble.desktop with Exec=frozen-bubble, yet its
WM_CLASS is ("perl", "perl") and its command line is as follows:
/usr/bin/perl /usr/bin/frozen-bubble
The existing servicesFromPid() (now split into servicesFromPid() and
servicesFromCmdLine()) does not find the frozen-bubble service because
it works with the leading executable in the command line.
In this patch, TryIgnoreRuntimes is introduced with a default of
"perl". In the new code, after the initial command line matching pass
fails, TryIgnoreRuntimes is checked for whether the leading command
line executable is on the list, and if so, a second command line
matching pass is run with the remainder of the process' command line,
now succeeding.
Note that the approach of "try one more thing" rather than checking
against TryIgnoreRuntimes first is deliberate: The Exec= key in many
.desktop files contains a complete command line prefixed with the
runtime executable. In those cases we don't want to ignore the runtime
executable, or matching would fail.
To complement this, the "perl" WM_CLASS is added to the
MatchCommandLineFirst rc key. Due to the shoddy metadata Frozen
Bubble already ended up in servicesFromPid() regardless, but this
saves some busywork for this WM_CLASS, which can reliably be presumed
bad.
The patch also fixes a small logic error in the match-command-line-
without-arguments block, where the result of a KServiceTypeTrader
query was ignored and immediately overridden by another.

Summary:
This is implemented by TasksModel and allows clients to reliably
query whether a row has an associated launcher. Useful for things
like Pin/Unpin action state or layout decisions.
Previously clients would have to reimplement something like
TaskTools::appsMatch on top of the model, which we absolutely do
not want to do - there should only be one copy of the app matching
logic for consistency's sake. In practice clients would do things
like fetch LauncherUrl and run it by launcherPosition(), which
omits appsMatch's AppId comparision, as an example of such unwated
drift. This approach also avoids the large performance overhead
involved.
The role is not implemented by the single-type or munging tasks
models as it has no use there.

Summary:
Previously we updated the prop after checking for
AbstractTasksModel::IsDemandingAttention on window closure, but
as the window is gone, we can't actually get state for it anymore,
so we always need to update.
To make up for it, this patch also optimizes the prop updates to occur
only once per insert/remove batch - this is a bit academic because
the source models currently only insert single rows at a time, but
it's good hygiene.

Summary:
We currently match Krita by Name. It's classClass is "krita",
but its DesktopEntryName is org.kde.krita.desktop. However,
Krita also installs numerous additional .desktop entries to
associate more file types by itself, all of which match by
name, and the first one in the list isn't the right one. All
of those extra .desktop files are NoDisplay=true however, so
we can filter them out, which brings the match list down to
the one and only .desktop file we care for.

Summary:
The new activity-aware implementation of
LauncherTasksModel::setLauncherList() would only accept the passed list
when it changed any activities associations, not when the order changed.
This would effectively turn TasksModel::move involving launcher tasks
into a no-op.
Rearranging launchers works like this:
1. A client calls TasksModel::move one or many times. TasksModel::move
updates TasksModel's internal sort mapping and implements it, causing
a visible order change in any views.
2. When it is done calling move(), the client calls
TasksModel::syncLaunchers. TasksModel::syncLaunchers calls
LauncherTasksModel::setLauncherList with a new list derived from
its sort mapping, and updates its sort mapping in expectation of
row indices changing in the launcher tasks source model.
Due to the above bug, the sort mapping would be adjusted in expectation
of changes the launcher tasks model would not actually do, appearing to
undo the moves the next time a view is updated from source data.

WM_CLASS instance and general classes are checked against StartupWMClass
prior to most rewrite and mapping rules, and prior to the DesktopEntryName
and Name checks.
This matches the fd.o spec more closely and makes Chrome Apps and
LibreOffice work without special mapping rules, which is also a speed
win.

Differential Revision: https://phabricator.kde.org/D4680
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.

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).

We can therefore drop this rule.

for some reason KServiceTypeTrader refuses to match a .desktop

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.

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.
