Remote Indexer faults when indexing a binary string

[ripta.pasay@…]

This happens using ferret-0.11.4 on ruby-1.8.5 [i686-linux], gcc-3.4.6.

When indexing the contents of the attached file, the remote ferret server (using the DRb server) disconnects the client. The following message appears in the ferret_server.out file:

/usr/local/lib/ruby/gems/1.8/gems/ferret-0.11.4/lib/ferret/index.rb:298: [BUG] Segmentation fault

The relevant portion of ferret_server.log is also attached in its own separate file.

Sorry, I'm afraid this isn't enough information for me to work on this problem. If you can find a way for me to reproduce it, I'll definitely take a look at it.

Since there is no more information for this problem after 2 months I'll now close the ticket. If you can come up with a way for me to reproduce the problem here, please feel free to reopen the ticket.

This code (ferret_crasher.rb)

require 'rubygems'
require 'ferret'
index = Ferret::Index::IndexWriter.new :default_field => 'content', :path => '/tmp/ferret_seg_test'
index.add_document({:content=>"http://xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx\""})

consistently crashes on my server:

$ ruby ferret_crasher.rb
ferret_crasher.rb:4: [BUG] Segmentation fault
ruby 1.8.5 (2006-08-25) [i486-linux]

if i change http in the content to some rubbish, nothing happens. http, https, ftp would crash ferret.

Great, thanks for the excellent bug report. I'm onto it.

This has been fixed in trunk. This particular bug was also causing problems for the highlighter when highlighting matching urls and that has also been fixed. Thanks.
