Ruby methods for adding switch event forwarding entry

There are three Ruby methods provided for adding switch event forwarding entries:

add_forward_entry_to_all_switches
add_forward_entry_to_switch
add_forward_entry_to_switch_manager

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

add_forward_entry_to_all_switches event_type, trema_name

This method will add trema_name to all existing switches and switch manager's
event forwarding entry list of the specified event_type.

add_forward_entry_to_switch dpid, event_type, trema_name

This method will add an entry to a switch specified by dpid.
It will add trema_name to the switch's
event forwarding entry list of the specified event_type.

add_forward_entry_to_switch_manager event_type, trema_name

This method will add trema_name to the switch manager's
event forwarding entry list of the specified event_type.

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

Scenarios

add_forward_entry_to_all_switches event_type, trema_name
add_forward_entry_to_switch dpid, event_type, trema_name
add_forward_entry_to_switch_manager event_type, trema_name

add_forward_entry_to_all_switches event_type, trema_name

Given

a file named "nw_dsl.conf" with:

vswitch { datapath_id 0x1 }

And

a file named "AddEntryToAllTest.rb" with:

class AddEntryToAllTest  Controller
  include SwitchEvent

  def switch_ready datapath_id
    add_forward_entry_to_all_switches event_type, "new_controller" do | success |
      raise "Failed to add forwarding entry to all switches" if not success
      info "Successfully added a forwarding entry of event_type."
      dump_forward_entries_from_switch datapath_id, event_type do | success, services |
        raise "Failed to dump forwarding entry from a switch" if not success
        info "Dumping switch #{datapath_id.to_hex}'s forwarding entries of event_type : #{services.inspect}"
      end
      dump_forward_entries_from_switch_manager event_type do | success, services |
        raise "Failed to dump forwarding entry from the switch manager" if not success
        info "Dumping switch manager's forwarding entries of event_type : #{services.inspect}"
      end
    end
  end
end

When

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

And

wait until "AddEntryToAllTest" is up

And

*** sleep 1 ***

Then

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

Successfully added a forwarding entry of event_type.

And

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

Dumping switch manager's forwarding entries of event_type : [switch_manager_event_list]

And

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

Dumping switch 0x1's forwarding entries of event_type : [switch_event_list]

Examples:
event_type	switch_manager_event_list	switch_event_list
:vendor	"new_controller", "AddEntryToAllTest"	"new_controller", "AddEntryToAllTest"
:packet_in	"new_controller", "AddEntryToAllTest"	"new_controller", "AddEntryToAllTest"
:port_status	"new_controller", "AddEntryToAllTest"	"new_controller", "AddEntryToAllTest"
:state_notify	"new_controller", "AddEntryToAllTest"	"new_controller", "AddEntryToAllTest", "switch_manager"

add_forward_entry_to_switch dpid, event_type, trema_name

Given

a file named "nw_dsl.conf" with:

vswitch { datapath_id 0x1 }

And

a file named "AddEntryToSwitchDaemonTest.rb" with:

class AddEntryToSwitchDaemonTest  Controller
  include SwitchEvent

  def switch_ready datapath_id
    add_forward_entry_to_switch datapath_id, event_type, "new_controller" do | success, services |
      raise "Failed to add forwarding entry to switch" if not success
      info "Successfully added a forwarding entry of event_type to switch #{datapath_id.to_hex} : #{services.inspect}"
    end
  end
end

When

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

And

wait until "AddEntryToSwitchDaemonTest" is up

And

*** sleep 1 ***

Then

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

Successfully added a forwarding entry of event_type to switch 0x1 : [switch_event_list]

Examples:
event_type	switch_event_list
:vendor	"new_controller", "AddEntryToSwitchDaemonTest"
:packet_in	"new_controller", "AddEntryToSwitchDaemonTest"
:port_status	"new_controller", "AddEntryToSwitchDaemonTest"
:state_notify	"new_controller", "AddEntryToSwitchDaemonTest", "switch_manager"

add_forward_entry_to_switch_manager event_type, trema_name

Given

a file named "AddEntryToSwitchManagerTest.rb" with:

class AddEntryToSwitchManagerTest  Controller
  include SwitchEvent
  
  oneshot_timer_event :test_start, 0
  def test_start
    add_forward_entry_to_switch_manager event_type, "new_controller" do | success, services |
      raise "Failed to add forwarding entry to switch manager" if not success
      info "Successfully added a forwarding entry of event_type to switch manager : #{services.inspect}"
    end
  end
end

When

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

And

wait until "AddEntryToSwitchManagerTest" is up

And

*** sleep 1 ***

Then

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

Successfully added a forwarding entry of event_type to switch manager : [switch_manager_event_list]

Examples:
event_type	switch_manager_event_list
:vendor	"new_controller", "AddEntryToSwitchManagerTest"
:packet_in	"new_controller", "AddEntryToSwitchManagerTest"
:port_status	"new_controller", "AddEntryToSwitchManagerTest"
:state_notify	"new_controller", "AddEntryToSwitchManagerTest"
