[Piuparts-devel] Bug#588313: piuparts: needs to detect changes in diversions

[Andreas Beckmann]

Package: piuparts
Version: 0.38
Severity: normal

Hi,

piuparts does not detect changes to the diversions (done with
dpkg-divert) that remain after purging (usually a forgotten removal ...)

I currently use the following two hook scripts to do this checking, but
I think this could be solved more elegant internally. The
/var/lib/dpkg/diversions file is easily parsable (but the order of the
records may change when diversions are added and removed).

BEGIN post_setup_90-save-diversions:
#!/bin/sh
set -e

dpkg-divert --list | sort > /tmp/.piuparts.diversions.initial
END post_setup_90-save-diversions

BEGIN post_purge_90-check-diversions:
#!/bin/sh
set -e

dpkg-divert --list | sort > /tmp/.piuparts.diversions.final

if ! cmp -s /tmp/.piuparts.diversions.initial /tmp/.piuparts.diversions.final
then
    echo "ERROR: diversions have changed"
    diff /tmp/.piuparts.diversions.initial /tmp/.piuparts.diversions.final
    exit 1
fi

rm /tmp/.piuparts.diversions.final
END post_purge_90-check-diversions
