Hi,
I''m having some strange/random crashes with ferret when using different
programs on the same index.
I created a script to reproduce the errors:
http://www.sig11.org/~seb/ferret_crash.rb
Usage:
In one terminal run: ruby ferret_crash.rb first
In another terminal: ruby ferret_crash.rb
Errors I usually get are but it is really random:
/usr/lib/ruby/gems/1.8/gems/ferret-0.11.3/lib/ferret/index.rb:542:in
`close'': End-of-File Error occured at <except.c>:93 in xraise
(EOFError)
Error occured in store.c:216 - is_refill
current pos = 0, file length = 0

I tried using the last trunk version but i didn''t help.
Thanks.

Hi Sebastien, I''ve had the same segfault problems and I''m told these are now fixed in subversion and will be in the next release. As for your other problems, Ferret does not support multiple processes writing to the same index. It''s recommended that you use a DRb service to achieve this instead. John.

Thanks for the quick answer. I tried it with the last svn release, the segfaults are gone. I''ll have look at DRb.

Isn''t the ferret-write.lck supposed to take care of this problem? John Leach wrote:> ... Ferret does not support multiple processes writing to the same index. ...-- Sebastien Pahl - Rift Technologies spahl at rift.fr -- Posted via http://www.ruby-forum.com/.
