active shelled out to pidof on every read, blocking the main loop and
missing our own recorder handle. Track the spawned Gio.Subprocess for
an exact answer and cache the external pidof probe for 2s.
Resets the cache at ownership boundaries (start/stop).
Repeated set_label() on every tick destroys and recreates the button's
internal label; after enough redraws GTK3 drops its visibility. Capture
the label once and update via set_text() instead.
run_auth_dialog now returns a thread-safe dismiss callable so polkitd
cancellations can close the dialog from any thread. connect_sysauth_service
wires the agent signals to the dialog: show on begin, respond on submit,
re-prompt on failure, dismiss on cancel.
polkitd ends the authentication session the moment the BeginAuthentication
D-Bus reply returns, so replying immediately aborted every attempt with
'No session for cookie'. The invocation is now held until respond() or
cancel() resolves it, and cancelled sessions return
org.freedesktop.PolicyKit1.Error.Cancelled.
Also export the agent on the system bus (polkitd addresses agents by the
system-bus unique name used for registration) and authenticate through
polkit-agent-helper-1 via socket activation or setuid fallback so PAM
runs as root, instead of the old direct Respond call that only works
for uid 0.
Break self -> animator -> lambda cycles in smooth switch and flat scale
by stopping animators and disconnecting value handlers on destroy. Drop
mutual OSD window/osd refs and clear the applet active-popup class ref.
Suspend the dock animation loop when nothing animates, pause the desktop
system info poller while unmapped, replace the OSD watchdog polling with
a single shot at expiry, lower the notch visualizer tick rate, and
cancel outstanding dock occlusion/rebuild timers on teardown.
P0 leak fixes: context/action menus destroyed on deactivate, config
callbacks unregistered in settings widgets, recorder and server signal
IDs stored and disconnected, bluetooth client closed and unsubscribed,
rfkill timer removed, seek timers cancelled, dropdown and options menus
freed, app name cache LRU-bounded.
Fix desktop 'Edit Widgets' and settings menu regressions by deferring
destroy out of Gtk signal handlers via GLib.idle_add.
Fix settings entry fields by connecting the activate signal explicitly
(Enter saves the value).
