[Robert Collins (lifeless)]

I believe this is a hardy python issue, not a bzr issue.

the _xmlplus module is not supplied or directly used by bzr AFAIK.

Not our bug

[Martin Pool (mbp)]

It's not a Bazaar bug; it's probably a Hardy problem in some python package. I'm not sure precisely which package.

This commanrd reproduces it:

  python -Werror -c 'import xml.etree.cElementTree'

mbp@grace% dpkg -S /usr/lib/python2.5/site-packages/_xmlplus
dpkg: /usr/lib/python2.5/site-packages/_xmlplus not found.

[Matthias Klose (doko)]

python -Werror -c 'import xml.etree.cElementTree' works fine for me on hardy.

apparently some things are used from the old / deprecated python-xml package during the test run, which is not anymore in sys.path directly to avoid the overlays with the xml code in python2.4 and python2.5.

  - bzr upstream should not rely on this package for tests, but use the xml code from the python2.4/python2.5 core library
  - the package should ignore the tests using python-xml, or b-d on python-xml and adding the module to sys.path
   directly

[Matthias Klose (doko)]

hmm, bzr itself doesn't use anything of the old xml code ...

[Matthias Klose (doko)]

offby1, please could you list the contents of /usr/lib/python2.5/site-packages/_xmlplus and /usr/lib/python2.5/site-packages/oldxml ?

[Launchpad Janitor (janitor)]

This bug was fixed in the package python-xml - 0.8.4-10ubuntu2

---------------
python-xml (0.8.4-10ubuntu2) hardy; urgency=low

  * Explicitely remove /usr/lib/python2.[345]/site-packages/_xmlplus,
    likely be left by an earlier python-central version. LP: #212917.

[Matthias Klose (doko)]

could not reproduce this with a gutsy -> hardy upgrade. Uploaded a new version which explicitely removes the old directory. If the python-xml package is already removed, please install it again (the current version), and remove it again.

[Martin Pool (mbp)]

That worked for me, thanks.
