Ruby

Folks,

Here is an announcement that the third preview of Ruby 1.8.7 has just
been released. Changes from the previous preview release include
fixes for a couple of security problems, some incompatibility issues
and many bugs that have been addressed since the last preview, and a
few backports including Symbol#to_proc that was temporarily backed
out after preview1.

The new version of Ruby includes many bug fixes, lots of feature
enhancements and some performance improvements since 1.8.6 while
maintaining stability and backward compatibility with the previous
release to a high degree, although there are ongoing efforts that need
to be done toward adopting RubySpec.

The source code package is available in three formats at the following
locations:

ftp://ftp.ruby-lang.org/pub/ruby/1.8/ruby-1.8.7-preview3.tar.bz2

Is the BasicObject class (from Ruby 1.9) included in Ruby 1.8.7?

Also, does OpenStruct derive from BasicObject in Ruby 1.8.7? So that we
no longer have to undef type and id to use those properties in our
OpenStructs?

require ‘ostruct’

class OpenStruct
undef id # deprecated in Ruby 1.8; removed in 1.9
undef type # same thing
end

Thanks for your consideration.

Thanks for the report, but unfortunately I cannot tell what’s causing
the segfault from what’s below. Could you rebuild ruby with -g given
in CFLAGS and give me a more precise stacktrace?

We’ve fixed some bugs since the preview3 release, so please try
checking out the latest revision from the ruby_1_8_7 branch.
