Ruby methods for deleting switch event forwarding entry

There are three Ruby methods provided for deleting switch event forwarding entries.

delete_forward_entry_from_all_switches
delete_forward_entry_from_switch
delete_forward_entry_from_switch_manager

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

delete_forward_entry_from_all_switches event_type, trema_name

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

delete_forward_entry_from_switch dpid, event_type, trema_name

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

delete_forward_entry_from_switch_manager event_type, trema_name

This method will delete trema_name from 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
they can be omitted if checking is not necessary.

Scenarios

delete_forward_entry_from_all_switches event_type, trema_name
delete_forward_entry_from_switch dpid, event_type, trema_name
delete_forward_entry_from_switch_manager event_type, trema_name

delete_forward_entry_from_all_switches event_type, trema_name

Given

a file named "nw_dsl.conf" with:

vswitch { datapath_id 0x1 }

And

a file named "DeleteEntryFromAllTest.rb" with:

class DeleteEntryFromAllTest  Controller
  include SwitchEvent

  def switch_ready datapath_id
    delete_forward_entry_from_all_switches event_type, "DeleteEntryFromAllTest" do | success |
      raise "Failed to delete forwarding entry from all switches" if not success
      info "Successfully deleted 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 ./DeleteEntryFromAllTest.rb -c nw_dsl.conf -d

And

wait until "DeleteEntryFromAllTest" is up

And

*** sleep 1 ***

Then

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

Successfully deleted a forwarding entry of event_type.

And

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

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

And

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

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

Examples:
event_type	switch_manager_event_list	switch_event_list
:vendor
:packet_in
:port_status
:state_notify		"switch_manager"

delete_forward_entry_from_switch dpid, event_type, trema_name

Given

a file named "nw_dsl.conf" with:

vswitch { datapath_id 0x1 }

And

a file named "DeleteFromSwitchDaemonTest.rb" with:

class DeleteFromSwitchDaemonTest  Controller
  include SwitchEvent

  def switch_ready datapath_id
    delete_forward_entry_from_switch datapath_id, event_type, "DeleteFromSwitchDaemonTest" do | success, services |
      raise "Failed to delete forwarding entry from switch" if not success
      info "Successfully deleted a forwarding entry of event_type from switch #{datapath_id.to_hex} : #{services.inspect}"
    end
  end
end

When

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

And

wait until "DeleteFromSwitchDaemonTest" is up

And

*** sleep 1 ***

Then

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

Successfully deleted a forwarding entry of event_type from switch 0x1 : [switch_event_list]

Examples:
event_type	switch_event_list
:vendor
:packet_in
:port_status
:state_notify	"switch_manager"

delete_forward_entry_from_switch_manager event_type, trema_name

Given

a file named "DeleteFromSwitchManagerTest.rb" with:

class DeleteFromSwitchManagerTest  Controller
  include SwitchEvent

  oneshot_timer_event :test_start, 0
  def test_start
    delete_forward_entry_from_switch_manager event_type, "DeleteFromSwitchManagerTest" do | success, services |
      raise "Failed to delete forwarding entry from switch manager" if not success
      info "Successfully deleted a forwarding entry of event_type from switch manager : #{services.inspect}"
    end
  end
end

When

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

And

wait until "DeleteFromSwitchManagerTest" is up

And

*** sleep 1 ***

Then

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

Successfully deleted a forwarding entry of event_type from switch manager : [switch_manager_event_list]

Examples:
event_type	switch_manager_event_list
:vendor
:packet_in
:port_status
:state_notify
