GServer implements a generic server

Gserver

GServer implements a generic server, featuring thread pool management, simple logging, and multi-server management. See HttpServer in sample/xmlrpc.rb in the Ruby standard library for an example of GServer in action.

Installation

Add this line to your application's Gemfile:

gem 'gserver'

And then execute:

$ bundle

Or install it yourself as:

$ gem install gserver

Usage

Using GServer is simple. Below we implement a simple time server, run it, query it, and shut it down. Try this code in irb:

require 'gserver'

#
# A server that returns the time in seconds since 1970.
#
class TimeServer < GServer
  def initialize(port=10001, *args)
    super(port, *args)
  end
  def serve(io)
    io.puts(Time.now.to_i)
  end
end

# Run the server with logging enabled (it's a separate thread).
server = TimeServer.new
server.audit = true                  # Turn logging on.
server.start

Now, point your browser to http://localhost:10001 to see it working.

# See if it's still running.
GServer.in_service?(10001)           # -> true
server.stopped?                      # -> false

# Shut the server down gracefully.
server.shutdown

# Alternatively, stop it immediately.
GServer.stop(10001)
# or, of course, "server.stop".

All the business of accepting connections and exception handling is taken care of. All we have to do is implement the method that actually serves the client.
