Can't run both server and clients from the same script.
Tasos Laskos
I've only been using BrB for a few hours now (great job btw) and I
think I've found a problem.
Long story short, my goal is to build a Grid of servers; that requires
servers to be able to also act as clients in order to gather
information about their peers (the rest of the servers/nodes).
However, it seems that when a Tunnel is instantiated before starting
the Reactor, instead of it blocking indefinitely it returns
immediately.
Here's some code that reproduces the problem:
brb_grid.rb:
--------------------
require 'brb'
port = ARGV.shift
if neighbour = ARGV.shift
puts ::BrB::Tunnel.create( nil, neighbour ).hello_block
end
public
def hello
'hello'
end
::EM::run do
::BrB::Service.start_service(
:object => self,
:host => 'localhost',
:port => port,
:verbose => true
)
end
--------------------
On one terminal:
ruby brb_grid.rb 1111
On a different terminal:
ruby brb_grid.rb 2222 brb://localhost:1111
The second terminal will output 'hello', the BrB service will run but
then the script will return immediately instead of blocking.
I'm new to EM so I may be missing something here, any ideas?
Cheers,

Sorry for the delay.
So yes the EM reactor never return, long time I haven't use BrB, but I used it in the past with a server connection to client too, it's just a matter of doing it after you init the service on the server, look at the example in the git repo!

The examples at the repo show a basic client-> server configuration with
the client and the server being in 2 different systems.
Can you give me an example of what you are talking about please?
Just to clarify:
I'm trying to have servers that can connect to other servers (i.e. the
servers will also act as clients to other servers),
however the first RPC call kills the local BrB::Service.
