Package: consolekit
Version: 0.2.10-2
Severity: normal
Hello,
on a system where ConsoleKit is only used sporadically, a race condition
caused by the interaction between D-Bus' activation code and
console-kit-daemon's backgrounding has surfaced.
If console-kit-daemon backgrounds quickly enough that the D-Bus code hasn't
returned to the caller yet, the caller receives the error "Launch helper
exited with unknown return code 0".
This can be demonstrated by the attached python script.
$ sudo killall /usr/sbin/console-kit-daemon
$ ./test-ck
Unable to use PackageKit: org.freedesktop.DBus.Error.Spawn.ChildExited:
Launch helper exited with unknown return code 0
(You might need to repeat the above steps a few times to reproduce.)
To avoid the race condition, the following change simply disables the
backgrounding in console-kit-daemon for the D-Bus activation case:
--- /usr/share/dbus-1/system-services/org.freedesktop.ConsoleKit.service

[D-BUS Service]
Name=org.freedesktop.ConsoleKit
-Exec=/usr/sbin/console-kit-daemon
+Exec=/usr/sbin/console-kit-daemon --no-daemon
User=root
The alternative would be to fix D-Bus to assume return code 0 is fine, as long
as someone continues to provide the requested service. So maybe this is a bug
in D-Bus and not in ConsoleKit.
Cheers, Fabian
