If you have experienced sporadic threading problems in the archive, a fix has
been checked into listen, as of r43360. After updating, future messages
should thread properly. To update messages already in the archive, you will
need to run a migration that will call reindex on each list's searchable
archive tool.
For our needs, the migration looked like this:
from StringIO import StringIO
from zope.component import getUtility
from Products.listen.interfaces import IListLookup
from Products.listen.interfaces import ISearchableArchive
def migrate_listen_archive_indexes(self):
out = StringIO()
ll = getUtility(IListLookup)
mappings = ll.showAddressMapping()
for mapping in mappings:
path = mapping['path']
try:
ml = self.unrestrictedTraverse(path)
except AttributeError:
continue
search_tool = getUtility(ISearchableArchive, context=ml)
indexes = search_tool.indexes()
try:
search_tool.manage_reindexIndex(ids=indexes)
except UnicodeDecodeError:
out.write('***** codec error for list: %s\n' % ml.title)
else:
out.write('migrated %s\n' % ml.title)
return out.getvalue()
Thanks,
Robert
