DRb Return Cant Jump Across Threads

Thomas Counsell

Hello,

I'm experimenting with adding DRb access to a wiki. When a method is
called through DRb from irb to the running wiki it always results in
the errors:

Server: /opt/local/lib/ruby/site_ruby/1.8/drb/drb.rb:726:in
`main_loop': return jump can't across threads (ThreadError)
Client: NameError: undefined method `name' called for from
(druby://localhost:8001)
/opt/local/lib/ruby/site_ruby/1.8/drb/drb.rb:632:in
`check_insecure_method' on the client.

Can anybody give me any hints on what I might have done wrong?

I'm running ruby 1.8.2 (2004-07-29) [powerpc-darwin7.5.0].

Many thanks

Tom

Two things to look for:

callcc

return in a block/proc
