Tools * The C++ :ref:`logger ` now has a "monitor mode" * The C++ :ref:`logger ` can now print :term:`event` collections * The Common Lisp :ref:`logger ` adjusts its display to the width of the containing terminal * The Common Lisp :ref:`logger ` can now print :term:`event` collections .. note:: For a more detailed list of fixed bugs, added features and other enhancements, see https://code.cor-lab.org/projects/rsb/versions/25. |project| 0.5 ============= .. note:: * |project| clients using the 0.5 version of |project| cannot generally communicate with clients using a previous |project| version. * The :term:`Spread` :term:`transport` is no longer active by default (see below). * The API is in some parts not backwards-compatible. The development activities in this cycle focused primarily on API improvements and the integration of :term:`causal vectors `. Moreover, complete compatibility for MSVC 2010 is now ensured and MacOS compatibility has been improved. In the process, about 60 issues have been created and subsequently resolved. This |project| release is available in the following forms: * Source archives * Pre-compiled self-installing archives * Debian packages for different |ubuntu| versions (new) These can be downloaded from the `0.5 jobs continuous integration server `_ or `repository server`_ respectively. As always, bugs, feature requests and enhancement proposals can be reported in the `issue tracker`_. General Changes * A tutorial is now included in the |project| source tree: "0.5" branch of |repository_tutorials| * Several introductory talks are now included in the |project| source tree: "0.5" branch of |repository_talks| * "RSB-related build jobs":https://ci.cor-lab.de/view/rsb-0.5 on the continuous integration sever have been reorganized. * Simple benchmarking tools are available in the ``rsbench`` project. * The ``#rsb`` IRC channel on the freenode network can now be used for additional support and discussion. * :ref:`Installation instructions ` have been improved. Network Protocol and Configuration * :term:`Causal vectors ` have been added to the network protocol. They allow to tag which :term:`event` or :term:`events ` caused a given :term:`event`. * The default :term:`transport` configuration has been changed: * The inprocess :term:`transport` is now enabled by default * The :term:`Spread` :term:`transport` is now disabled by default and has to be enabled explicitly when network communication is desired. This can e.g. be done by adding the user configuration file :file:`~/.config/rsb.conf` with the following content: .. code-block:: ini [transport.spread] enabled = 1 [transport.inprocess] enabled = 0 Tools * The C++ :ref:`logger ` now displays :term:`causal vectors `. * The Common Lisp :ref:`logger ` now displays :term:`causal vectors `. * The Common Lisp :ref:`logger ` now displays configurable statistics. * The Common Lisp :ref:`logger ` now allows configuring the columns in the "compact" formatting style. * The :ref:`call ` tool for performing RPCs from the commandline has been added. C++ * Support for :term:`causal vectors ` has been added. * The client API for creation and configuration of :term:`participants ` and :term:`events ` has been simplified. * Convenience functions for participant creation without the factory have been added. (Suggested by: Robert Haschke) * ``OriginFilter`` has been added. * Compilation time has been reduced. (Suggested by: Matthias Rolf) * A name-clash with a Qt macro has been resolved (Reported by: Matthias Rolf) * :term:`Event` dispatching now allows multiple threading strategies. * Performance Improvements * Caching of :term:`Spread` group names * ``<``-comparison of ``EventId`` s Java * Support for :term:`causal vectors ` has been added. * ``OriginFilter`` has been added.

Common Lisp * Support for :term:`causal vectors ` has been added. .. note:: For a more detailed list of fixed bugs, added features and other enhancements, see https://code.cor-lab.org/projects/rsb/versions/21. |project| 0.4 ============= .. note:: |project| clients using the 0.4 version of |project| cannot communicate with clients using a previous |project| version. The development activities in this cycle focused primarily on extending and optimizing the wire format and improving the usability of and support for protocol buffer message objects as event payloads. In the process, more than 30 issues have been created and subsequently resolved. * Downloadable source archives of this version are available in the `Files section `_ of the Redmine project. * pre-compiled archives of |project| can be found as artifacts on the `continuous integration server`_. As always, bugs, feature requests and enhancement proposals can be reported in the `issue tracker`_. Network Protocol for :term:`Spread`-based Communication * The eagerly computed, mandatory unique id field of :term:`events ` is now lazily computed from a static id and a :term:`sequence number`. :term:`Events ` can be transmitted without computing the id. This change saves 12 bytes in each :term:`notification` sent over the wire. (Thanks: Stefan Herbrechtsmeier) * Incompatible wire format versions can now be detected by means of a trick which does not incur any runtime overhead in space or time. This enabled removal of the ``version`` field in :term:`notifications `, saving four bytes in each notification sent over the wire. * The method field of :term:`events ` is now fully specified and used in request/reply communication. C++ * In addition to blocking request/reply invocation, a future-based asynchronous interface is now available. * Several performance problems related to :term:`scope` and :term:`event` construction have been fixed. (Thanks: Matthias Rolf, Arne Nordmann) Java * Request/reply communication with blocking and asynchronous invocation modes has been implemented. * A :term:`converter` registration and selection mechanism and a generic :term:`converter` for `Google protocol buffers`_ data holder classes have been added. Python * Request/reply communication with blocking and asynchronous invocation modes has been implemented. * A :term:`converter` for `Google protocol buffers`_ data holder classes has been added. Common Lisp * Request/reply communication with blocking and asynchronous invocation modes has been implemented. .. note:: For a more detailed list of fixed bugs, added features and other enhancements, see https://code.cor-lab.org/projects/rsb/versions/17.
