Bug 279917 – app-emulation/xen-tools-3.4.0-r1 does not run with python 2.6

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Sven 2009-08-01 15:26:04 UTC]

Hi,

Run the command "xm dmesg" and you will get a an error message about a missing class called "FakeSocket". Some googling reveiled, that this class could have been masked deprecated since 2007 (shame on upstream) and it might have been removed in python 2.6.


Reproducible: Always

Steps to Reproduce:

Please paste the output of 'emerge --info' into a bugzilla comment to assist the maintainers in resolving this issue

Additionally please include the error message in an attachment as well.

I have pyython-2.6 installed and am running Xen without the problem reported below. I do get a warning when running xm commands but otherwise no problems:

/usr/lib64/python2.6/site-packages/xen/util/acmpolicy.py:20: DeprecationWarning: the sha module is deprecated; use the hashlib module instead
  import sha

If python was upgraded to 2.6 after you installed xen did you run the python-updater script?

Yes, and xen-tools was re-emerged. Since that time, it doesn't run anymore.

If I select python 2.5 again (via eselect) and re-emerge xen-tools, then it works again.

# cat test.py
from httplib import FakeSocket

# python2.6 test.py
Traceback (most recent call last):
  File "test.py", line 1, in <module>
    from httplib import FakeSocket
ImportError: cannot import name FakeSocket

# python2.5 test.py
(no error message)


My python use-flags may be relevant:
# emerge python -vp
These are the packages that would be merged, in order:
Calculating dependencies... done!

I also took a look at the httplib.py of python 2.6. It seems, that FakeSocket depends on some import of ssl.

Enabling the SSL use-flag for python fixed the problem for me.

Hmm, looks like xen-tools needs a dependency change
