Description Warren Togami 2007-10-14 01:19:18 UTC
Probing for video card:   Intel Corporation Mobile 945GM/GMS, 943/940GML Express
Integrated Graphics Controller
Starting graphical installation...
Traceback (most recent call last):
  File "/usr/sbin/anaconda", line 904, in <module>
  File "/usr/sbin/anaconda", line 484, in setDispatch
    self.dispatch = dispatch.Dispatcher(self)
AttributeError: 'module' object has no attribute 'Dispatcher'

While attempting to use anaconda to build a chroot, it fails with this error
while python-ruledispatch is installed.  This is because the dispatch module
provided by ruledispatch has a higher precedence than anaconda's dispatch in

-        sys.path.append('/usr/lib/anaconda')
+        sys.path.insert(0,'/usr/lib/anaconda')

This makes it work, although it is messy in the others append other private
paths and anaconda needs to be thoroughly tested to be sure this doesn't break

Comment 2 Chris Lumens 2007-11-20 19:26:01 UTC
This breaks the RHupdates mechanism.  What needs to happen is that the
/usr/lib/anaconda paths be inserted into sys.path after all the updates paths.

Comment 3 Toshio Ernie Kuratomi 2008-01-16 15:22:40 UTC
I'm not sure what the "updates paths" consist of, but the code in the following
patch might be sufficient if I've guessed right.  It seems a bit hacky, though.

A cleaner way to do this would be to make an anaconda module (either in
python_sitearch or as a subdirectory of %{_libdir}/anaconda) and put all the
code in there.  Then the code will be properly namespaced and you'll be able to
write unambiguous import statements like::
  from anaconda import dispatch
