Get the ‘current’ server.
In the context of execution taking place within the main thread of a dRuby server (typically, as a result of a remote call on the server or one of its objects), the current server is that server. Otherwise, the current server is the primary server.
If the above rule fails to find a server, a DRbServerNotFound error is raised.
# File lib/drb/drb.rb, line 1644 def current_server drb = Thread.current['DRb'] server = (drb && drb['server']) ? drb['server'] : @primary_server raise DRbServerNotFound unless server return server end
