require "socket"
require "thread"

#
# GServer implements a generic server, featuring thread pool management,
# simple logging, and multi-server management.  See HttpServer in 
# <tt>xmlrpc/httpserver.rb</tt> in the Ruby standard library for an example of
# GServer in action.
#
# Any kind of application-level server can be implemented using this class.
# It accepts multiple simultaneous connections from clients, up to an optional
# maximum number.  Several _services_ (i.e. one service per TCP port) can be
# run simultaneously, and stopped at any time through the class method
# <tt>GServer.stop(port)</tt>.  All the threading issues are handled, saving
# you the effort.  All events are optionally logged, but you can provide your
# own event handlers if you wish.
#
# === Example
#
# 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.
#
# === Advanced
#
# As the example above shows, the way to use GServer is to subclass it to
# create a specific server, overriding the +serve+ method.  You can override
# other methods as well if you wish, perhaps to collect statistics, or emit
# more detailed logging.
#
#   connecting
#   disconnecting
#   starting
#   stopping
#
# The above methods are only called if auditing is enabled.
#
# You can also override +log+ and +error+ if, for example, you wish to use a
# more sophisticated logging system.
#
