I have ported a zope product running on zope 2.5.1 to zope 2.9. The application works fine with no error messages in the log. Now I want to port an old Data.fs from zope 2.5.1 with the Product Data on. It seem to work fine by just copying it to the new zope 2.9 var directory. But every time I restart I get the error messages written at the bottom of this email. As said everything seems to work fine even searching. There is no error messages after zope has started. So, does anyone know what errors the below messages could cause, and what I can do to correct them? 2007-01-12T10:12:37 INFO ZODB.Mount Opening database for mounting: '142907168_1016702399.626485' ------ 2007-01-12T10:12:37 INFO ZODB.Mount Mounted database '142907168_1016702399.626485' at /temp_folder ------ 2007-01-12T10:12:37 INFO Zope.ZCatalog Start migration of indexes for Control_Panel/Products/ExternalMethod/Help/catalog ------ 2007-01-12T10:12:37 WARNING ZODB Could not import class 'BTree' from module 'BTree' ------ 2007-01-12T10:12:37 WARNING ZODB Could not import class 'UnTextIndex' from module 'SearchIndex.UnTextIndex' ------ 2007-01-12T10:12:37 WARNING ZODB Could not import class 'UnKeywordIndex' from module 'SearchIndex.UnKeywordIndex' ------ 2007-01-12T10:12:37 WARNING ZODB Could not import class 'BTree' from module 'OIBTree' ------ 2007-01-12T10:12:37 WARNING ZODB Could not import class 'BTree' from module 'IOBTree' ------ 2007-01-12T10:12:37 INFO Zope.ZCatalog Finished migration of indexes for Control_Panel/Products/ExternalMethod/Help/catalog ------ 2007-01-12T10:12:37 ERROR OFS.subscribers _delObject() threw Traceback (most recent call last): File "/usr/lib/zope2.9/lib/python/OFS/subscribers.py", line 149, in callManageBeforeDelete ob.manage_beforeDelete(item, container) File "/usr/lib/zope2.9/lib/python/HelpSys/HelpTopic.py", line 85, in manage_beforeDelete self.unindex_object() File "/usr/lib/zope2.9/lib/python/HelpSys/HelpTopic.py", line 95, in unindex_object self.get_catalog().uncatalog_object(prefix + self.url()) File "/usr/lib/zope2.9/lib/python/Products/ZCatalog/ZCatalog.py", line 599, in uncatalog_object self._catalog.uncatalogObject(uid) File "/usr/lib/zope2.9/lib/python/Products/ZCatalog/Catalog.py", line 383, in uncatalogObject rid = uids.get(uid, None) AttributeError: get ...
