I've seen messages from users saying that Xron with the patch worked fine for them with Zope 2.4.0. So why doesn't it work for me ?

Probably because you are creating a new Schedule Zcatalog, whereas they were using one already created in a prior version of Zope.

As far as I can tell the addIndex error results from changes to Catalog.py made to support PluggableIndexes. I haven't been paying attention to this development, so I have no clue what to do to make Xron compatible with PluggableIndexes.

Can anyone point me in the right direction?

Before you might have done this: self._catalog.addIndex('name', 'FieldIndex') You now need to do this: self._catalog.addIndex('name', UnIndex('name')) The same goes for KeywordIndex (UnKeywordIndex) and TextIndex (UnTextIndex). You'll also need from SearchIndex.UnIndex import UnIndex from SearchIndex.UnTextIndex import UnTextIndex from SearchIndex.UnKeywordIndex import UnKeywordIndex in there somewhere. I patched tracked to adapt to either the old or new styles: field_indexes=('type', 'numid', 'exemptions', 'date', 'stage', 'priority', 'requester', 'from', 'private') keyword_indexes=('issueOwners','subscribers','traitVals') text_indexes=('text_content',) addIndex=self._catalog.addIndex # try to add indexes in Zope 2.3 style. If this fails # then add them in Zope 2.4 style try: for name in field_indexes: addIndex(name, 'FieldIndex') for name in keyword_indexes: addIndex(name, 'KeywordIndex') for name in text_indexes: addIndex(name, 'TextIndex') except TypeError: from SearchIndex.UnIndex import UnIndex from SearchIndex.UnTextIndex import UnTextIndex from SearchIndex.UnKeywordIndex import UnKeywordIndex for name in field_indexes: addIndex(name, UnIndex(name)) for name in keyword_indexes: addIndex(name, UnKeywordIndex(name)) for name in text_indexes: addIndex(name, UnTextIndex(name)) -- Steve Alexander Software Engineer Cat-Box limited

Thanks Steve and Chris, If someone wants to try this out, the patches should go in the Schedule.py module of Xron. There are two calls to addIndex() in the __init__ method. I don't have 2.4.0 running yet and probably won't for awhile; so, good luck. I'm also including Chris' follow-up at the end so everything is in one message. -- Loren

I'm not sure this is a good idea.

I think you're supposed to do something like:

from Products.PluginIndexes.FieldIndex.FieldIndex import FieldIndex

...and use that in addIndex.

cheers,

Chris

I think you have to tailor Steve's patch a little more. Try something like this (untested): def __init__(self, id='Schedule', title='Scheduled Event Catalog'): self.id = id self.title = title self.threshold = 1000 self._v_total = 0 self._catalog = ZCatalog.Catalog() self._catalog.addColumn('id') self._catalog.addColumn('meta_type') self._catalog.addColumn('nextEventTime') self._catalog.addColumn('absolute_url') self._catalog.addIndex('nextEventTime', UnIndex('nextEventTime')) self._catalog.addIndex('absolute_url', UnIndex('absolute_url')) -- Loren

o.k. I tried patching Schedule.py like this (Win2k, Zope2.4.0):

and got this error:
