[xmlblaster] xmlBlaster C++ client library with native SOCKET plugin available



Hi,

our C++ client library has now a protocol plugin
which uses our native xmlBlaster SOCKET protocol
to talk to the Java xmlBlaster server, see

  http://www.xmlblaster.org/xmlBlaster/doc/requirements/client.cpp.socket.html

The SOCKET protocol is described here:

  http://www.xmlblaster.org/xmlBlaster/doc/requirements/protocol.socket.html

The C++ plugin wraps the C-client SOCKET implementation
which is described in detail here:

  http://www.xmlblaster.org/xmlBlaster/doc/requirements/client.c.socket.html

The C++ plugin code is available with cvs.

FEATURES:
=========
 o You can compile the C++ client library to contain
   the SOCKET and the CORBA plugin simultaneously
   or only one of them.

 o The SOCKET protocol tunnels callbacks through the same
   TCP/IP socket which eliminates some firewall problems.

TODO:
=====
  The plugin has the limitations as described in the above
  client.c.socket requirement:

 o Invoking xmlBlaster from within the callback thread (in update() function)
   will deadlock, a thread pool implementation will be added
   to resolve this issue.
 o publishOneway() and publishArr() are not yet implemented
   (They are useful for higher performance only)

COMPATIBILITY:
==============
 o The C and the C++ client API has minor changes,
   please read the xmlBlaster/CHANGES file on how to adapt
   your existing C/C++ clients.

   http://www.xmlblaster.org/xmlBlaster/CHANGES

COMPILE example (SOCKET only):
========
 cd xmlBlaster

 Edit build.properties to only contain these settings:
   COMPILE_SOCKET_PLUGIN=1
   COMPILE_CORBA_PLUGIN=1
   corba.product = NONE
 plus the xerces XML settings

 build cpp

EXAMPLE:
========
 Try (xmlBlaster/demo/c++/bin)

   HelloWorld2 -help

 for a list of command line arguments

 If you have compiled for example the CORBA and SOCKET plugin
 you can switch the protocol used on the fly:

  HelloWorld2 -protocol IOR

  HelloWorld2 -protocol SOCKET

enjoy

Marcel

PS: The plugin is currently tested with g++ 2.x, g++ 3.x and icc 7.x,
    Windows follows.
