Hi Dave ( again ! ) I''ve been searching for a while into my extension code to understand what was the matter, and Florent Solt who hasn''t got my extension has the same problem, so it figured to be a ferret problem.. Unfortunately, we''re unable at the moment to reproduce it in a little code so you could debug easilier... I''m working on it. Heres the issue : In the index, there are a lot of stuff with a type field, and we''re experiencing the same bug with just type => hardware or mixed datas. We''ve got around 12400 docs with this type, here are the queries (THEY ARE ALL LAUNCHED IN A _NEW_ INSTANCE OF FERRET ! (with the same index of course)): this one works fine :>> INDEX.search(''type:hardware'').to_s=> "TopDocs: total_hits = 12490, max_score = 1.751220 [\n\t13997 \"61426\": 1.751220\n\t13998 \"61427\": 1.751220\n\t13999 \"61428\": 1.751220\n\t14000 \"61429\": 1.751220\n\t14001 \"61430\": 1.751220\n\t14002 \"61431\": 1.751220\n\t14003 \"61432\": 1.751220\n\t14004 \"61433\": 1.751220\n\t14005 \"61434\": 1.751220\n\t14006 \"61435\": 1.751220\n]\n" and this one doesn''t.. :>> INDEX.search(''type:hardware'', :limit => :all).to_s/usr/local/lib/site_ruby/1.8/ferret/index.rb:718: [BUG] rb_gc_mark(): unknown data type 0x18(0x89b4268) non objectruby 1.8.4 (2005-12-24) [i486-linux] Aborted i tried to get to the limit point and got it : works :>> INDEX.search(''type:hardware'', :limit => 9719).to_sdon''t work :>> INDEX.search(''type:hardware'', :limit => 9720).to_s/usr/local/lib/site_ruby/1.8/ferret/index.rb:718: [BUG] Segmentation fault ruby 1.8.4 (2005-12-24) [i486-linux] BUT ! if, IN THE SAME INSTANCE OF RUBY, i do the first and then the second one, it works !>> INDEX.search(''type:hardware'', :limit => 9719).to_s...works>> INDEX.search(''type:hardware'', :limit => 9720).to_s...works>> INDEX.search(''type:hardware'', :limit => :all).to_sWORKS. So i guess there''s a problem in result memory allocation, i don''t know what i could add to help you, i''m trying to reproduce it in a little code... Ah, just another detail, this is how our index is created : INDEX_OPTIONS = { :path => path, :auto_flush => false, :max_buffer_memory => 0x4000000, :max_buffered_docs => 100000, :use_compound_file => false} INDEX = Ferret::Index::Index.new(INDEX_OPTIONS) but i tried without any max_* and it''s the same... Tell me what i can do to help if i don''t manage to reproduce it in a pastable code. Thanks by advance, Regards, Jeremie ''ahFeel'' BORDIER -- Posted via http://www.ruby-forum.com/.
