Hello all,
anyone using DRb and macruby?
I know next to nothing about DRb but its giving me some crashes in
macirb that it is not in irb, for setting variables on the server side.
For example (I have coloured responses so its easier to see the
difference between input and output):
with the simple server below running:
require 'drb'
class TestServer
attr_accessor :var_a, :var_b
end
aServerObject = TestServer.new
DRb.start_service('druby://localhost:9000', aServerObject)
DRb.thread.join
#irb in a terminal:
dev:~ johnshea$ irb
>> require 'drb'
=> true
>>

#so far so good, now irb in another terminal:

#yep thats fine, now another terminal

/Library/Frameworks/MacRuby.framework/Versions/0.4/usr/lib/ruby/1.9.1/
drb/drb.rb:961: [BUG] destination 0x7fff5fbf7308 isn't in the auto zone
MacRuby version 0.4 (ruby 1.9.1) [universal-darwin9.5, x86_64]
-- stack frame
(0xc0860): 0004
--snip-- see the rest of the crash below
the crash log suggests that this is the problem line in drb.rb which is:
if IO.select([...@socket], nil, nil, 0)
#oops go back to a previous irb session
>> p obj.var_b
100
=> nil
>> obj.var_b = 99
=> 99
#hmm that works fine.
anyone got any ideas?
Cheers,
John
