drb on windows not connecting

[Joel VanderWerf]

The drb examples just hang without doing anything. However, the tsvr.rb
and clnt.rb (not drb, just TCP), work fine, so I don't think it's a
firewall issue (I've tried shutting down the ZoneAlarm firewall, just to
be sure).

The only sign of any connection is that exiting the server causes an
exception in the client:

==== TERM 1 ====
C:\ruby\tmp\drb-sample>ruby name.rb druby://localhost:7640
druby://localhost:7640
[return] to exit


C:\ruby\tmp\drb-sample>

==== TERM 2 ====

C:\ruby\tmp\drb-sample>ruby namec.rb druby://localhost:7640

=================

This is with 1.8.0 (2003-08-04) mswin32.

TIA for any suggestions.

The drb examples just hang without doing anything.

In name.rb, just replace the gets after the puts '[return] to exit'
with DRb.thread.join and see the fun ;-)

However, the tsvr.rb

Which tsvr.rb are you talking of ..I don't see it my sample dir ?

HTH,

This is a solution to similar problems with some other drb
programs too (like rinda/ring.rb) on Win 32.
Unfortunately, this solution makes stoping the server process a pain.
I haven't found a graceful exit solution yet.

Ok, found it. Thanks,

Ok, got it now.

Anyone know why the behavior differs from linux to windows?

Strangely, it is installed in

\ruby\doc\Ruby-1.8.0\sample

Seems like it should be in

\ruby\samples

I suppose #gets hangs the other threads? Ugh. Oh, well. I'm writing GUI
stuff anyway, so I don't care too much about the console on windows.

Another option is to use srvany.exe -- I've had this work well (although
srvany.exe is only available in the NT Resource Kit, I believe -- not free)
