Habarisoft released new versions of Habari Client libraries for Delphi and Free Pascal application integration with free open source message brokers.

Tested with current message broker versions

  • Apache ActiveMQ 5.10.0
  • Apollo 1.7
  • HornetQ 2.4.0.Final
  • Open MQ 5.1 b09
  • RabbitMQ 3.3.5

Fixes

  • Unhandled Exceptions in WaitForReceiptFrame are re-raised to notify client code about the exception
  • Fixed compiler error undeclared identifier ‘ShortDateFormat’ when using Log4D with newer Delphi versions
  • Fixed Free Pascal compiler warning about deprecated ShortDateFormat in Log4D
  • Fixed Free Pascal compiler error ‘unknown identifier: TClassList’ and run time error SIGSGEV (Linux)
  • Fixed CurrentUTC method by using LocalTimeToUniversal (Free Pascal)

Improvements

  • changed the Receive methods to update the heart-beat timestamp when heart-beats arrive, even if no message has been received. With this change, it is no longer required to call the CheckHeartbeat method periodically if no message arrived
  • ITextMessage.Text is now of type string instead of WideString
  • all persistent messages will be sent with a receipt request
  • improved Free Pascal and Linux support
  • Eliminate duplicate code in map message transformers
  • Added a check that the STOMP frame ends with a NUL byte and raise a EBTStompError if a non-NUL byte is found, to indicate a STOMP protocol violation (and a potential loss of data)

New features

  • Added a transformer class for map message exchange based on the Superobject JSON library
  • Added a transformer class for map message exchange based on the default XML parser library in Delphi (IXMLDocument)
  • Added class TBTConnectionBuilder which can be used to construct a connection by chaining configuration methods (experimental/unsupported code)
  • Added Free Pascal version of ConsumerTool application
  • Added unit tests for durable subscriptions
  • Added unit tests and a mock server to verify that the library detects a connection loss
  • Added Free Pascal version of throughput test application

DUnit and FPCUnit tests
