I have a strange problem while trying to communicate from macruby to
running drb process.
Only one request is passing, on second I'm getting error.
I tested same simple code in ruby 1.9.1 and Ruby 1.8.6 and there all
works ok.
Server can be run with any version of Ruby, and everything works
except when client is running with macruby.
Here is the sample code for client and server to reproduce error.
Sample server, returns new value for each call on increment:
require 'drb'
class Incrementer
def initialize
@value = 0
end
def increment
@value += 1
end
end
service = DRb.start_service("druby://localhost:4242", Incrementer.new)
print "service started on port 4242\n"
DRb.thread.join
Sample client, displays server value:
require 'drb'
DRb.start_service
server = DRbObject.new_with_uri('druby://localhost:4242')
p server.increment #this line, works as expected
p server.increment #this line raises error
And the error is:
/Library/Frameworks/MacRuby.framework/Versions/0.4/usr/lib/ruby/1.9.1/
drb/drb.rb:961: [BUG] destination 0x7fff5fbfbe48 isn't in the auto zone
MacRuby version 0.4 (ruby 1.9.1) [universal-darwin9.0, x86_64]
