Threading in ruby is retarded .....?~!

Ruby

I’m running the latest version an Ruby and the way threads work makes
absolutely no sense to me…

I have the simplest use of threads:

Thread.new do
while true
  puts "Enter command"
        if gets.chomp=='exit'
        break;

end
puts 'Ended service'
end

Thread.new do
  while service != nil
  server.start
end end

$user[:drbserver]=DistributedSearch.new($user,$database)
service=DRb.start_service("druby://localhost:#{$config[:drbport]}",$user[:drbserver])
DRb.thread.join

When I run this DRb does NOT start until after I type in exit! Why does
a new thread block the main thread wtf??? I’m guessing this is not
normal and has something to do with either DRb or Webrick. Isn’t there a
way that these two would just run their own threads…? It makes it
useless to me if I can’t run both in the same program

Are you using windows? This is a known problem:

You could try it in JRuby, which uses normal operating system threads.
No thread should be prevented from running unless you explicitly make it
happen.

Are you using windows? It is broken, not ruby. Don’t use gets in
the main thread.

this code won’t run at all. post a complete, but minimal, example
and someone might be inclined to fix it for you. as it stands i have
no idea wtf??? service or wft??? server are.

the code above has at least one race condition in it as it stands:
you race here

while service != nil

and

service = …

in some cases service will be nice the first time, in others not.
perhaps this intended but, again, it’s hard to see without a
meaningful code posting.

you’ll have to help use help you if you want to get complete answer.
