Druby with 1.7.x?

ruby-talk
1

Hello all…

I’ve just looked at druby for the first time
in a few months.

I’m now using 1.7.3 on Win98.

I’ve tried drb 1.3 and 2.0b1, and I can’t seem
to get the simplest things to work.

Anyone know what’s up??

Thanks,
Hal

Are you using the version of drb on each machine you’re trying to use
it with? (disregard the question if you’re just trying to use drb on one
machine with localhost)

I got it to work on Win XP (Pro) using ruby 1.7.3 (2002-11-17)
[i386-mswin32] and drb-2.0b1

Let us know what exactly happens when you try simplest of the things.

For example, this could be a simple thing to try:

drb_srvr.rb

require ‘drb’

class TstSrvr
def time_now
"It is: " + Time.now.to_s
end

def bye(msg="")
   puts msg
   Thread.new {sleep(0.1); exit(1)}
   nil
end

end

srvObj = TstSrvr.new
DRb.start_service(“druby://localhost:5555”,srvObj)
DRb.thread.join

···

#------------------------

#drb_client.rb
require ‘drb’
STDOUT.sync = true

cliObj = DRbObject.new(nil,“druby://localhost:5555”)

5.times { |i| puts cliObj.time_now; sleep(2); }

cliObj.bye(‘Bye Bye’)

Thanks, that’s a good reference point.

I’ll try this and report.

OK, this is working fine.

But the things I tried from the “sample”
directory don’t work; and the stock_watcher
example from TRW ch9 doesn’t work.

Let me give a concrete example:

darray and darrayc - I start the server:
ruby darray.rb
druby://host-computer:3995
[return to exit]

And I start the client:
ruby darrayc.rb druby://host-computer:3995

And it just hangs until I kill the server
with a return.

I tried “localhost” also – not sure what it
means by “host-computer” – no difference.

Hi.

Please use ‘DRb.thread.join’ instead of ‘gets’.
in windows, $stdin.gets will block. maybe.
