Subject: [PATCH 1/4] tests: Iterate mainloop during launch test
When launching an application, we wait for the DBus response from
systemd before executing the binary. Because of this the main loop needs
to be iterated for spawning to completed and the file to be created.
Without this the test will time out if GLib was able to connect to the
session bus.

Subject: [PATCH 2/4] gdesktopappinfo: Move launched applications into
transient scope
Try to move the spawned executable into its own systemd scope. To avoid
possible race conditions and ensure proper accounting, we delay the
execution of the real command until after the DBus call to systemd has
finished.
From the two approaches we can take here, this is better in the sense
that we have a child that the API consumer can watch. API consumers
should not be doing this, however, gnome-session needs to watch children
during session startup. Until gnome-session is fixed, we will not be
able to change this.
The alternative approach is to delegate launching itself to systemd by
creating a transient .service unit instead. This is cleaner and has e.g.
the advantage that systemd will take care of log redirection and similar
issues.
Note that this patch is incomplete. The DBus call is done in a "fire and
forget" manner, which is fine in most cases, but means that "gio open"
will fail to move the child into the new scope as gio quits before the
DBus call finishes.

Subject: [PATCH 3/4] gdesktopappinfo: Handle task completion from spawn
function
This allows delaying the return of the task until all dbus calls (in
particular the ones to setup the scope) have finished.
This fixes the behaviour of the previous commit which would not
correctly move the process into the scope if the application exited
right after the task returned.

From 67d764ecd52b4f7e972eb355a41cd90b8dcca10c Mon Sep 17 00:00:00 2001
From: Benjamin Berg <bberg@redhat.com>

Subject: [PATCH 4/4] gdesktopappinfo: Add SourcePath= to transient systemd
units
systemd allows setting a SourcePath= which shows the file that the unit
has been generated from. KDE is starting to set this and it seems like a
good idea, so do the same here.
See https://invent.kde.org/frameworks/kio/-/merge_requests/124
