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_s
don'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_s
WORKS.
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
