Please, need help. Ive upgraded using buildout from 4.0.5 to 4.1.3, but when
I try to upgrade (dry run) there are about 5 messages with:
"There are unresolved or circular dependencies. Graphviz diagram: ..."
Some import steps in Plone had circular dependencies for a while. I has
meanwhile been fixed, but I think you may still see this when upgrading.
Usually you can ignore this. It is a warning, not an error.
and finally the dry run says:
Step collective.blogging.reset-layers has an invalid import handler
Class Products.PloneboardSubscription.NotificationTool.NotificationTool not
found for tool portal_pbnotification
Upgrade aborted. Error:
Traceback (most recent call last):

"/usr/local/Plone/buildout-cache/eggs/Products.GenericSetup-1.6.4-py2.6.egg/Products/GenericSetup/tool.py",
line 123, in importToolset

TypeError: 'NoneType' object is not callable
GenericSetup is a bit too strict here. It keeps a list of required
tools that have been registered by Plone or by add-ons. One of those
required tools it missing, probably because the add-on that requires it
is no longer in use.
What happens is that GenericSetup first prints out the info about this
missing class in the Products.PloneboardSubscription package and then a
few lines further it tries to use that class anyway and fails. I have
fixed that in GenericSetup but there is no release yet with the new code.
Best option is to make that class available. Add
Products.PloneboardSubscription to your buildout and try again. If you
are no longer using this product, then you may need to uninstall it
while still on Plone 4.0.5 (it needs to be available in the buildout
then too).
If that does not work out, you can try the latest code from here:
http://svn.zope.org/Products.GenericSetup/branches/1.6/
The relevant change is here:
http://svn.zope.org/Products.GenericSetup/branches/1.6/Products/GenericSetup/tool.py?rev=123871&r1=123456&r2=123871
You could edit your
/usr/local/Plone/buildout-cache/eggs/Products.GenericSetup-1.6.4-py2.6.egg/Products/GenericSetup/tool.py
file directly and make the same change. I do not officially recommend
that, but it gets the job done. :-)
I hope this helps,
