Hi Andy - any progress on this? Although the buildd's are running older
kernels, it seems that the DEP-8 Jenkins environment is running 3.19 and
is thus causing upstart tests to fail. For example:
https://jenkins.qa.ubuntu.com/view/Wily/view/AutoPkgTest/job/wily-adt-
Running with a 3.19.0-8-generic kernel I see:
- The Upstart test_job_process test fail within a few seconds when run in a
loop looking for the errror.
- My test program in #13 also finds the bug within ~30 seconds on my test
system.
Using the kernel in #11, I have run both tests simultaneously
I've written a basic program that surfaces this bug. To recreate:
$ cd /tmp
$ tar xvf bug-1429756.tgz
$ cd bug-1429756

The problem is not observed when the only connections to upstart are the
standard upstart bridges (since they use nih_dbus_connect()).
For reference, here is nih_dbus_setup() which includes one or more calls
that unity seemingly should be calling itself:
http://bazaar.launchpad.net/~ubuntu-
This problem can now be demonstrated with a single connection to upstart
that makes the following calls:
dbus_connection_open()
nih_dbus_proxy_new ()
The problem is not seen if the app instead calls:
- nih_dbus_connect (upstart_session, disconnect_handler)

C program to trigger this bug. Run it in an environment with
UPSTART_SESSION set (such as a desktop/Touch environment), then run the
about-to-be attached spam.sh script.

Program attached in #51 demonstrates the incorrect calling behaviour. To
demonstrate the correct behaviour change the #if0/else/endif such that
rather than calling dbus_connection_open(), the program calls
nih_dbus_connect().
nih_dbus_connect(): No memory growth.
dbus_connection_open(): Memory
Persistent D-Bus connections are as expected (1 / bridge and 1 for
unity-panel-service).
Ephemeral D-Bus connections are being handled correctly and removed from the
control_conns list.

Still unclear why memory is being cached in Upstart address space, but
I'm starting to think this might be a libdbus issue.
What is triggering the memory rise though is unity-panel-service:
stopping this from running results in no memory increase within the
Session Init.
** Also affects: unity
Right - recall that I am testing on i386 as I don't have mako/maguro :)
However, note that on Touch, the upstart code in unity8
(plugins/Unity/Indicators/indicatorsmanager.cpp) is almost identical to
the upstart code in unity-panel-service (unity/services/panel-
service.c).
Is it possible to
Re #41, interesting that unity-panel-service *is* installed on Touch
image though :)

Valgrinding the session init shows that most of the memory is correctly

The problem is triggered by init/control.c:control_emit_event_emitted().
It looks like Upstart itself is clearing up memory, but either dbus
isn't, or upstart is missing a dbus unref call.
