Package: quantum-plugin-cisco,quantum-plugin-linuxbridge-agent,quantum-plugin-linuxbridge,quantum-plugin-nicira,quantum-plugin-openvswitch-agent,quantum-plugin-openvswitch,quantum-plugin-ryu-agent,quantum-plugin-ryu Version: 2012.1-6 Severity: important User: debian...@lists.debian.org Usertags: piuparts replaces-without-breaks
Hi,
during a test with piuparts and EDOS tools I noticed your package causes
removal of files that also belong to another package.
This is caused by using Replaces without corresponding Breaks.
The installation sequence to reproduce this problem is
apt-get install python-quantum/wheezy
# (1)
apt-get install quantum-plugin-cisco/sid
apt-get remove quantum-plugin-cisco/sid
# (2)
The list of installed files at points (1) and (2) should be identical,
but the following files have disappeared:
/usr/lib/python2.6/dist-packages/quantum/plugins/cisco/__init__.py ->
../../../../../../share/pyshared/quantum/plugins/cisco/__init__.py owned
by: quantum-plugin-cisco
...
/usr/lib/python2.6/dist-packages/quantum/plugins/cisco/ucs/cisco_ucs_plugin.py
->
../../../../../../../share/pyshared/quantum/plugins/cisco/ucs/cisco_ucs_plugin.py
owned by: quantum-plugin-cisco
/usr/lib/python2.7/dist-packages/quantum/plugins/cisco/client/cli.py ->
../../../../../../../share/pyshared/quantum/plugins/cisco/client/cli.py
owned by: quantum-plugin-cisco
...
/usr/lib/python2.7/dist-packages/quantum/plugins/cisco/ucs/cisco_ucs_plugin.py
->
../../../../../../../share/pyshared/quantum/plugins/cisco/ucs/cisco_ucs_plugin.py
owned by: quantum-plugin-cisco
/usr/share/pyshared/quantum/plugins/cisco/__init__.py owned by:
quantum-plugin-cisco
...
/usr/share/pyshared/quantum/plugins/cisco/ucs/cisco_ucs_plugin.py owned
by: quantum-plugin-cisco
This is a serious bug violating policy 7.6, see
http://www.debian.org/doc/debian-policy/ch-relationships.html#s-replaces
and also see the footnote that describes this incorrect behavior
http://www.debian.org/doc/debian-policy/footnotes.html#f53
The quantum-plugin-cisco package has the following relationships with
python-quantum:
Conflicts: n/a
Breaks: n/a
Replaces: python-quantum (<< 2012.1-5.1)
Depends: python-quantum
The version in wheezy (2012.1-5) had
Replaces: python-quantum (<< 2012.1-3)
Breaks: python-quantum (<< 2012.1-3)
Depends: python-quantum
which looked better.
Or what about making the Depends on python-quantum strictly versioned:
Depends: python-quantum (= ${source:Version})
to ensure the package versions can't be mixed (and you don't need to
add a Breaks in that case).
