DRb and signals

Ruby
1

Using DRb appears to disable signal handlers in Ruby, at least in
1.8.4. Is there any way to work around this?

Compare:

trap( “SIGINT” ) { puts “foo” ; exit 0 }
loop do sleep 1 end

with:

require ‘drb’
DRb.start_service
trap( “SIGINT” ) { puts “foo” ; exit 0 }
loop do sleep 1 end

In the second case, sending the process a SIGINT appears to have no
effect at all…

Not seeing it:

$ ruby -v -
ruby 1.8.4 (2005-12-24) [powerpc-darwin8.4.0]
require ‘drb’
DRb.start_service
trap( “SIGINT” ) { puts “foo” ; exit 0 }
loop do sleep 1 end
^Cfoo
$

There’s a ^D in there under the ^C, but it got eaten.

I got the same result as Eric.

Hmm, okay, thanks. I guess it’s an HP-UX issue.
