Public bug reported:
In certain areas, Ubuntu Touch needs to use D-Bus activation to start
Upstart jobs.
= Overview =
This bug is for tracking the re-enabling of Upstart service activation
in D-Bus.
In certain areas, Ubuntu Touch needs to use D-Bus activation to start
Upstart jobs. The version of D-Bus in Ubuntu no longer supports Upstart
service activation which has resulted in work-arounds being introduced
for Touch that attempt to simulate proper service activation with
varying degrees of success.
= Background =
D-Bus in Ubuntu used to support Upstart service activation. The
lp:ubuntu/dbus logs shows that it was added in r112:

* Upload to quantal (lp: #1014850)

- use "Breaks: unity-services (<< 6.0.0-0ubuntu6)", the new dbus
eavedropping protection was creating issues with previous versions
[ Iain Lane ]
* Merge with Debian experimental for the new stable series. Remaining Ubuntu
changes:
- Install binaries into / rather than /usr:
+ debian/rules: Set --exec-prefix=/
+ debian/dbus.install, debian/dbus-x11.install: Install from /bin
- Use upstart to start:
+ Add debian/dbus.upstart.
+ debian/control: Add upstart dependency.
+ debian/dbus.postinst: Use upstart call instead of invoking the init.d
script for checking if we are already running.
+ debian/control: versioned dependency on netbase that emits the new
deconfiguring-networking event used in upstart script.
- 20_system_conf_limit.patch: Increase max_match_rules_per_connection for
the system bus to 5000 (LP #454093)
- 81-session.conf-timeout.patch: Raise the service startup timeout from 25
to 60 seconds. It may be too short on the live CD with slow machines.
- Add 0001-activation-allow-for-more-variation-than-just-system.patch,
0002-bus-change-systemd-activation-to-activation-systemd.patch,
0003-upstart-add-upstart-as-a-possible-activation-type.patch,
0004-upstart-add-UpstartJob-to-service-desktop-files.patch,
0005-activation-implement-upstart-activation.patch: Patches from Scott
James Remnant to implement Upstart service activation. Not upstream.
Disable patches since they do not apply and this facility is unused
anyway.
* Remove systemd BDs; not appropriate for Ubuntu.
At some point [1], the lp:ubuntu/dbus branch lost the ability to support
Upstart service activation [2] as the patches were dropped.
[1] - Can't find out exactly when since lp:ubuntu/dbus is not current:
Most recent Ubuntu version: 1.6.12-0ubuntu8
Packaging branch version: 1.6.12-0ubuntu1
Packaging branch status: OUT-OF-DATE
[2] - See debian/patches/series Where the following patches are
commented out:
0001-activation-allow-for-more-variation-than-just-system.patch
0002-bus-change-systemd-activation-to-activation-systemd.patch
0003-upstart-add-upstart-as-a-possible-activation-type.patch
0004-upstart-add-UpstartJob-to-service-desktop-files.patch
0005-activation-implement-upstart-activation.patch
= Plan =
The existing patches may need slight rework to apply now. It would be
highly preferable if upstream D-Bus merge Upstart service activation
since dbus-daemon already provides a '--systemd-activation' option.
However, the ideal would be a consistent and generic service activation
approach which does not require hard-coding particular init daemon names
anywhere.
