Bug Description

see the openjdk build logs, e.g.

  https://launchpad.net/ubuntu/+source/openjdk-6/6b20-1.9-0ubuntu1

is this a metacity configuration error, or an xvfb error?

the last working build was on Jul 30:
https://launchpad.net/ubuntu/maverick/+source/openjdk-6/6b20~pre2-0ubuntu2

mkdir -p bin
( \
   echo '#!/bin/sh'; \
   echo 'metacity &'; \
   echo 'pid=$!'; \
   echo 'sleep 3'; \
   echo '"$@"'; \
   echo 'kill -9 $pid'; \
 ) > bin/my-jtreg-run
chmod 755 bin/my-jtreg-run
echo 'xvfb-run -a -e xvfb-run.log -s "-extension GLX" my-jtreg-run "$@"' > bin/my-xvfb-run
if ! /bin/sh bin/my-xvfb-run true ; then \
   echo "error running $(cat bin/my-xvfb-run)"; \
   cat xvfb-run.log; \
   echo 'xvfb-run -a -e xvfb-run.log -s "$@"' > bin/my-xvfb-run; \
   if ! /bin/sh bin/my-xvfb-run true ; then \
     echo "error running $(cat bin/my-xvfb-run)"; \
     cat xvfb-run.log; \
     rm -f bin/my-xvfb-run; \

I can confirm this bug. I got some build failed on a PPA.
Here is one of those https://launchpad.net/~gnome-split-team/+archive/ppa/+build/1982159
The package uses xvfb and Metacity when taking some screenshots to generate the *doc package.

In the error handling branch, the following call is erroneous:

As to the question of how it entered the error path, I can't reproduce the issue on maverick (pasting in the code and running it on a laptop seems to work fine for me). However, from the error messages in the description:

Window manager warning: Failed to contact configuration server; the most common cause is a missing or misconfigured D-Bus session bus daemon. See http://projects.gnome.org/gconf/ for information. (Details - 1: Failed to get connection to session: Cannot spawn a message bus without a machine-id: Unable to load /var/lib/dbus/machine-id: Failed to open file '/var/lib/dbus/machine-id': No such file or directory)

...this seems to be suggesting your dbus service is missing. Is that a possibility?

The build log in comment #6 doesn't really give enough detail to be sure what the error is, other than just that metacity couldn't be started up:

JAVA Harness
EXEC Xvfb
EXEC metacity
KILL Xvfb
KILL metacity
Exception in thread "main" java.lang.RuntimeException:
metacity didn't start
 at Harness.checkAlive(Harness.java:322)

make: *** [debian/stamp-makefile-build] Error 2
dpkg-buildpackage: error: debian/rules build gave error exit status 2

So, would be interesting to see a more detailed log, but seems quite possible it could be the same bug.

Looking at the log from comment #6 it looks like dbus, libdbus, dbus-x11 et al get installed. I can't tell that the dbus service was actually started up though.

Guillaume Mazoyer (respawneral) wrote :

Until Maverick, the build always worked. With Maverick, the build works in a local pbuilder but fails due to xvfb and metacity (apparently) on Launchpad. That is how I concluded that it was probably related to this bug.
 but I'm not sure at 100%.

Bryce Harrington (bryce) wrote :

I spoke with kees about this this evening. X doesn't depend directly on dbus; it sounds like it is metacity's dbus dependency which is faulting here. Metacity exits with an error, so xvfb propagates that error up.

Andrew Cowie (afcowie) wrote :

If it's a case of a DBus dependency (and if not, we're swerving off topic here) then the question is how to run a "private" DBus instance for the build in question.

I ran into this ~2 years ago in that I had to run a a gnome-settings-daemon privately under the Xvfb for metacity's themes to work, but that *broke* when it all moved to DBus because gnome-settings-daemon would quit with an error saying there already was already such a daemon one on the bus ... ie, the real Desktop's one!

So how to start a new DBus channel that offers test / build isolation but which everything running under that (X server?) would find (rather than the user's real one, I don't know.

the failure mentioned in comment #7 is a followup error (trying to run xvfb without xserver args (-s ...)). the primary failure is still to get metacity starting / working the chroot.

While this may be a metacity bug, i'd still like to see xvfb tested during the build of xorg-server in an attempt to detect future failures.

according to pitti, metacity has to be launched using dbus-launch, apparently the dependency on gconf requires this in maverick.

Right, running metacity through "dbus-launch" should work, and I believe Matthias confirmed that on UDS. Can this be closed?
