Rails - Nov 2005 - Ferret on rails--lock doesn't get released when webrick exits

I''m no doubt doing something wrong here since I just started using
ferret.  I''m following this tutorial:

http://wiki.rubyonrails.com/rails/pages/HowToIntegrateFerretWithRails

My ferret_env.rb file looks like this:

require ''ferret''
module FerretConfig
  include Ferret

  INDEX = Index::Index.new(:path => File.dirname(__FILE__) +
''/../../searchindex'')
end

When I load webrick for the first time, everything works fine.  But
when I exit with ctrl-c and try to load it again, I get this:

=> Booting WEBrick...
/usr/lib/ruby/gems/1.8/gems/ferret-0.2.2/lib/ferret/store/fs_store.rb:226:in
`obtain'': could not obtain lock:
./script/../config/../config/environments/../../searchindex/ferret-a214f46c3947bc95b17cb835bf48ae91write.lock
(RuntimeError)
        from
/usr/lib/ruby/gems/1.8/gems/ferret-0.2.2/lib/ferret/index/index_writer.rb:99:in
`initialize''
...

Is there anything I can do to cause the lock to be released when webrick exits?

Thanks,
Carl

In Ferret_environment.rb I have added following line
  Dir["#{FT_PATH}/**/*.lock"].each{|f| File.unlink f}
Just remove all *.lock files on startup. I am not sure that it is the best
solution, but it works for me.

Hi, Carl,

please have a look at 
http://article.gmane.org/gmane.comp.lang.ruby.rails/26859 and use the 
approach that luke describes. This is favorable to the approach that 
I''ve described in the tutorial. You might also have a look at 
http://ferret.davebalmain.com/trac/ticket/6

regards
Jan Prill
