Thanks Jens, that makes sense. I started with the following addition
to RDig::Searcher
# Returns <tt>true</tt> if RDig's IndexReader has the latest
index loaded. False otherwise.
def latest?
@ferret_searcher.reader.latest?
end
I fired up two script/console instances. In the first I called
ClassB.rebuild_index, and in the second console I called
RDig.searcher.latest? and received the following seg fault.
>> RDig.searcher.latest?
./script/../config/../config/../vendor/gems/rdig-0.3.4/lib/rdig/
search.rb:36: [BUG] Bus Error
ruby 1.8.4 (2005-12-24) [i686-darwin8.6.1]
Did I break a Ferret rule of some kind by having a reader looking at
the version of an index that is being rebuilt?
Thanks again.
