Possible bug when creating a Ferret::Search::Sort object?

Ruby Apps Ferret
1

I may have run across a bug in Ferret: if throws a segmentation fault
when I try to create a Sort object using the default fields (SCORE and
DOC_ID), but setting reverse to true.

Here’s the minimal example:

#!/usr/bin/env ruby
require ‘rubygems’
require ‘ferret’

Ferret::Search::Sort.new

Ferret::Search::Sort.new(
[
Ferret::Search::SortField::SCORE,
Ferret::Search::SortField::DOC_ID
],
false
)

Ferret::Search::Sort.new(
[
Ferret::Search::SortField::SCORE_REV,
Ferret::Search::SortField::DOC_ID_REV
],
false
)

Ferret::Search::Sort.new(
[
Ferret::Search::SortField::SCORE,
Ferret::Search::SortField::DOC_ID
],
true
)

You should get something like this when creating the last object:

$ruby sort.rb
sort.rb:23: [BUG] Segmentation fault
ruby 1.8.6 (2007-09-24) [x86_64-linux]

Aborted

Again, this is with Ferret 0.11.6 in Linux.

Is this a known problem that’s being worked on, or should I report it
at the Trac tool on ferret.davebalmain.com?

Hi,

this works fine for me with 0.11.6 with stock Ubuntu and Debian Ruby
versions:

ruby 1.8.6 (2007-06-07 patchlevel 36) [i486-linux] (Ubuntu 7.10)
ruby 1.8.5 (2006-08-25) [x86_64-linux] (Debian 4.0 (stable))

irb(main):001:0> require ‘ferret’
=> true
irb(main):002:0> Ferret::Search::Sort.new(
irb(main):003:1* [
irb(main):004:2* Ferret::Search::SortField::SCORE,
irb(main):005:2* Ferret::Search::SortField::DOC_ID
irb(main):006:2> ],
irb(main):007:1* true
irb(main):008:1> )
=> Sort[!, !]
irb(main):009:0> Ferret::VERSION
=> “0.11.6”

Cheers,
Jens

Works fine for me as well using CentOS 5 and OSX Leopard.

I’m using Ferret 0.11.6 on Gentoo Linux:
ruby 1.8.6 (2007-09-24 patchlevel 111) [x86_64-linux]

So maybe this is a Ruby 1.8.6-p111 bug?
