These are the only cases 100% safe to apply the renaming of the
testcase class names to match the file names.
All other cases are not safe, because they are missing namespace
and may enter into name conflicts. Adding namespaces is not as
simple as imagined because it implies to, also, add a good number
of modifications to core. See the issue for more details.
The recordsets used for search indexing sometimes return results
which are invalid (e.g. cannot be found in database). When this
happens, the result in the iterator for the recordset will be
false. Due to a bug, the iterator used to stop when it encountered
a false value, which prevented indexing from getting past the
problematic record.
In addition, the iterator that skips future data resulted in the
current() function of its parent indicator being called twice per
entry, which meant that search indexing called get_document()
twice as many times.
