[Zope] Data.fs gone crazy

[Steve Spicklemire]

Hi Tom,

	I just constructed this scenario:

1) Install a Python Product that is a base class for some ZClasses.

2) Install some ZClasses that inherit from the Python Product class

3) Delete the Python Product and the ZClasses

You may now have (I did) some "ghost" zclass entries in the Product
registry. The only way I found to get rid of them was to run the code
below. (stop Zope, cd to 'lib/python',  execute fixit.py from the
command line.) You might try running it a few times with the last two
lines commented out to make sure your only removing the zclasses you
mean to. You might also make a backup of your Data.fs before you do
anything else. I have no idea if this has any other nasty side effects,
but it worked for me.

Good Luck!

fixit.py:

import Zope

x = Zope.app(  )

theList = list( x._getProductRegistryData('zclasses'))

newList = []
for d in theList:
    if d['id'] == 'the name of your zclass':
        print "Skipping  .. ", d
    else:
        newList.append(d)

print newList

x._setProductRegistryData( 'zclasses', tuple(newList ))

get_transaction().commit()
