Documentation of the MyTransaction tool used for example.test.

INTRODUCTION

The MyTransaction tool is used to test the longterm-transaction-feature of rbmqmsgque.

To test this feature the client connect to the server and send two service-calls:

  • one longterm-transaction-service-call using the low-api
  • one longterm-transaction-service-call using the high-api

The service-call itself is quite simple:

  • the private part is a string : Privat_Data_1 or Privat_Data_2
  • the public part is an integer : 1111 or 2222

The GOAL for this test is:

  • test the longterm-transaction-feature
  • test the BufferListCheckOptionC with and without default-value
  • test the callback-feature with and without error

CODE client

require "rbmqmsgque"
include PyMsgque::MkKernel
include PyMsgque::MqMsgque

def callback(ctx)
  ctx.ReadT_START()
  myPrivateHandle = ctx.ReadC()
  ctx.ReadT_END()
  myServiceResult = ctx.ReadI()

  STDOUT.puts "myPrivateHandle=#{myPrivateHandle}, myServiceResult=#{myServiceResult}"
end

# setup the client-context
ctx = MqContextC.new
begin
  ctx.ConfigSetName("MyTransaction")

  # setup commandline arguments used for parsing
  args = MkBufferListC.CreateLA(ARGV)

  # check if the '--token' option is available, default "SRVC"
  token = args.CheckOptionC("--token", "SRVC")

  # connect to the server
  ctx.LinkCreate(args)

  # register callback
  ctx.ServiceCreate("CLB1", method(:callback))
   
  # send block using the LOW-Api
  ctx.SendSTART()
  ctx.SendT_START()
  ctx.SendC("Privat_Data_1")
  ctx.SendT_END()
  ctx.SendI(11111)
  ctx.SendEND_AND_TRANSACTION(token, "CLB1")
   
  # send block using the HIGN-Api -> same as above, but shorter
  ctx.Send("T", "CLB1", "#{token}:(C)I", "Privat_Data_2", 22222)
   
  # now we wait for exact ONE result of the "ctx"
  ctx.ProcessEvent(MqWaitOnEventE::OWN)

rescue Exception => ex
  ctx.ErrorCatch(ex)
ensure
  ctx.Exit()
