Ruby methods for setting switch event forwarding entry

There are two Ruby methods provided for setting switch event forwarding entry.

set_forward_entries_to_switch
set_forward_entries_to_switch_manager

These methods can be used by including the Trema::SwitchEvent module
in user controller code.

set_forward_entries_to_switch dpid, event_type, trema_names

This method will set the forwarding entries of the switch specified by dpid.
It will replace the switch's
event forwarding entry list of the specified event_type
to Array of trema-names specified by trema_names.

set_forward_entries_to_switch_manager event_type, trema_names

This method will replace the switch manager's
event forwarding entry list of the specified event_type
to Array of trema-names specified by trema_names.

All the above methods take a result handler as Ruby block, but
they can be omitted if checking is not necessary.

Scenarios

set_forward_entries_to_switch dpid, event_type, trema_names

Given

a file named "nw_dsl.conf" with:

vswitch { datapath_id 0x1 }

And

a file named "SetEntriesToSwitchDaemonTest.rb" with:

class SetEntriesToSwitchDaemonTest  Controller
  include SwitchEvent

  def switch_ready datapath_id
    set_forward_entries_to_switch datapath_id, event_type, ["SetEntriesToSwitchDaemonTest","Another"] do | success, services |
      raise "Failed to set forwarding entry to switch" if not success
      info "Successfully set a forwarding entries of event_type to switch #{datapath_id.to_hex} : #{services.inspect}"
    end
  end
end

When

I successfully run trema run ./SetEntriesToSwitchDaemonTest.rb -c nw_dsl.conf -d

And

wait until "SetEntriesToSwitchDaemonTest" is up

And

*** sleep 1 ***

Then

the file "../../tmp/log/SetEntriesToSwitchDaemonTest.log" should contain:

Successfully set a forwarding entries of event_type to switch 0x1 : [switch_event_list]

Examples:
event_type	switch_event_list
:vendor	"SetEntriesToSwitchDaemonTest", "Another"
:packet_in	"SetEntriesToSwitchDaemonTest", "Another"
:port_status	"SetEntriesToSwitchDaemonTest", "Another"
:state_notify	"SetEntriesToSwitchDaemonTest", "Another"

set_forward_entries_to_switch_manager event_type, trema_names

Given

a file named "SetEntriesToSwitchManagerTest.rb" with:

class SetEntriesToSwitchManagerTest  Controller
  include SwitchEvent

  oneshot_timer_event :test_start, 0
  def test_start
    set_forward_entries_to_switch_manager event_type, ["SetEntriesToSwitchManagerTest","Another"] do | success, services |
      raise "Failed to set forwarding entry to switch manager" if not success
      info "Successfully set a forwarding entries of event_type to switch manager : #{services.inspect}"
    end
  end
end

When

I successfully run trema run ./SetEntriesToSwitchManagerTest.rb -d

And

wait until "SetEntriesToSwitchManagerTest" is up

And

*** sleep 1 ***

Then

the file "../../tmp/log/SetEntriesToSwitchManagerTest.log" should contain:

Successfully set a forwarding entries of event_type to switch manager : [switch_manager_event_list]

Examples:
event_type	switch_manager_event_list
:vendor	"SetEntriesToSwitchManagerTest", "Another"
:packet_in	"SetEntriesToSwitchManagerTest", "Another"
:port_status	"SetEntriesToSwitchManagerTest", "Another"
:state_notify	"SetEntriesToSwitchManagerTest", "Another"
