RSB 0.9

Note

This RSB release is available in the following forms:

  • Source archives
  • Pre-compiled self-installing archives or executable binaries
  • Debian packages for different Ubuntu GNU/Linux versions
    • Starting with this release, the development version of RSB is packaged in the “testing” repository of our Debian repository server (as opposed to the “main” repository). So you need to add this repository to your apt sources list in case you want to install the development version via Debian packages.
  • Homebrew recipes and pypi packages
  • Maven package for rsb-java

These can be downloaded from the 0.9 jobs continuous integration server or repository server respectively. Installation instructions and links for downloading can be found in the RSB manual.

Changes

  • Integration of the new RSC plugin mechanism in the C++ implementation for transports and converters
  • Encapsulation of the spread transport into a separate plugin
  • Complete overhaul of the Java implementation to be in line with the remaining implementations
    • As a consequence, the public API has slightly changed, especially with respect to thrown exceptions
    • Implementation of the socket transport
  • Fixes in all implementations of the socket transport
  • The RPC API now supports some method signatures that did not work previously
  • Fixes for Windows compatibility
  • Documentation improvements

As always, bugs, feature requests and enhancement proposals can be reported in the issue tracker.

RSB 0.7

Note

This RSB release is available in the following forms:

  • Source archives
  • Pre-compiled self-installing archives or executable binaries
  • Debian packages for different Ubuntu GNU/Linux versions
  • Prototypical homebrew recipes and pypi packages (new)

These can be downloaded from the 0.7 jobs continuous integration server or repository server respectively. Installation instructions and links for downloading can be found in the RSB manual.

Changes

  • The TCP-socket transport is now fully implemented in C++, Python and Common Lisp and used by default there.
  • Error recovery, robustness and features of RSB
  • End-user documentation
  • Packaging and deployment
  • send tool

As always, bugs, feature requests and enhancement proposals can be reported in the issue tracker.

RSB 0.6

Note

RSB clients using the 0.6 version cannot generally communicate with clients using a previous RSB version.

This RSB release is available in the following forms:

  • Source archives
  • Pre-compiled self-installing archives or executable binaries
  • Debian packages for different Ubuntu GNU/Linux versions

These can be downloaded from the 0.6 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

  • All core components have been relicensed to LGPLv3.
  • Sub-projects have been cleaned up.
  • Manuals have been created and can be accessed at http://docs.cor-lab.org/rsb-manual/0.6/html. For a list of all documentation, see http://docs.cor-lab.org.
  • RSB programs now process PREFIX/etc/rsb.conf if such a file exists.

Tools

  • The C++ logger now has a “monitor mode”
  • The C++ logger can now print event collections
  • The Common Lisp logger adjusts its display to the width of the containing terminal
  • The Common Lisp logger can now print event collections

RSB 0.5

Note

  • RSB clients using the 0.5 version of RSB cannot generally communicate with clients using a previous RSB version.
  • The Spread 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 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 RSB release is available in the following forms:

  • Source archives
  • Pre-compiled self-installing archives
  • Debian packages for different Ubuntu GNU/Linux 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

Network Protocol and Configuration

  • Causal vectors have been added to the network protocol. They allow to tag which event or events caused a given event.

  • The default transport configuration has been changed:

    • The inprocess transport is now enabled by default

    • The Spread 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 ~/.config/rsb.conf with the following content:

      [transport.spread]
      enabled = 1
      
      [transport.inprocess]
      enabled = 0
      

Tools

  • The C++ logger now displays causal vectors.
  • The Common Lisp logger now displays causal vectors.
  • The Common Lisp logger now displays configurable statistics.
  • The Common Lisp logger now allows configuring the columns in the “compact” formatting style.
  • The call tool for performing RPCs from the commandline has been added.

C++

  • Support for causal vectors has been added.
  • The client API for creation and configuration of participants and 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)
  • Event dispatching now allows multiple threading strategies.
  • Performance Improvements * Caching of Spread group names * <-comparison of EventId s

Java

  • Support for causal vectors has been added.
  • OriginFilter has been added.

Python

  • Support for causal vectors has been added.
  • OriginFilter has been added.

Common Lisp

RSB 0.4

Note

RSB clients using the 0.4 version of RSB cannot communicate with clients using a previous RSB 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.

As always, bugs, feature requests and enhancement proposals can be reported in the issue tracker.

Network Protocol for Spread-based Communication

  • The eagerly computed, mandatory unique id field of events is now lazily computed from a static id and a sequence number. Events can be transmitted without computing the id. This change saves 12 bytes in each 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 notifications, saving four bytes in each notification sent over the wire.
  • The method field of 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 scope and event construction have been fixed. (Thanks: Matthias Rolf, Arne Nordmann)

Java

  • Request/reply communication with blocking and asynchronous invocation modes has been implemented.
  • A converter registration and selection mechanism and a generic 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 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.
