Bug#773253: jenkins: please add script to detect dpkg trigger cycles
Hi,
I made a number of modifications to jenkins but I fail to run bin/chroot-run.sh
locally by itself. So I gave up.
Instead, I created a Jessie chroot, copied Jenkins inside it and ran
bin/find_dpkg_trigger_cycles.sh to test.
The attached patch installs apt-file and dose-extra as the two additional
dependencies I had to install for the find_dpkg_trigger_cycles script.
Since this is running in Jessie, I also removed the python-arpy hack and rely
on dpkg instead.
Since I could not test this locally, I didn't touch job-cfg/dpkg.yaml, so this
still has to be done.
One remaining problem could be that there might be no /dev/stdin inside the
chroot. If this is the case, then we still have to use python-arpy or somehow
mount /dev and /proc (or only /proc and read from /proc/self/fd/0 instead).
This is until bug #616614 is fixed.
Thanks!
cheers, josch

Subject: [PATCH] find_dpkg_trigger_cycles: prepare for being run inside a
jessie chroot
- chroot is required because dose-ceve version in wheezy is too old
- in addition, with jessie the python-arpy hack can be dropped because
of too old dpkg version in wheezy
