obtained gcc-4.6.4.tar.bz2 from upstream website;upstream
verified gcc-4.6.4.tar.bz2.sig;
imported gcc-4.6.4 source tree from verified upstream tarball.
downloading a git-generated archive based on the 'upstream' tag
should provide you with a source tree that is binary identical
to the one extracted from the above tarball.
if you have obtained the source via the command 'git clone',
however, do note that line-endings of files in your working
directory might differ from line-endings of the respective
files in the upstream repository.

CORBA messages +are binary, not text oriented. They practically cary no "data wrapping" +information like XML <opening> </closing> tags. Hence CORBA +objects easier exchange large amounts of binary data. CORBA can work +in such data-intensive application areas as telecommunications or radio +broadcasting. Java programs connect to CORBA objects without care +about what platform they run on, where they exist in the network, or what +language they were written in. The remote CORBA objects appear to the +programmer as the ordinary Java objects and can be passed as +parameters in both remote or local method invocations. +</p><p> +The CORBA processing unit is divided into {@link org.omg.CORBA.Object} +that is exposed to the client and the servant +({@link org.omg.PortableServer.Servant} where the method, invoked on +object, is finally delegated. It can be multiple objects per servant or +multiple servants per object. The servant for particular object or +even particular call can be dynamically chosen at run time using +{@link org.omg.PortableServer.ServantManager}. +</p><p> +All stages of both local and remote invocations on CORBA objects can be +monitored and modified using {@link org.omg.PortableInterceptor.Interceptor}. +The interceptors can add an extra data to the CORBA message (these data +can be later accessed by other interceptor on remote side). +</p> +<a name="overview"> +<h4>Overview of the currently implemented CORBA functionality</h4> +The CORBA implementation in the Classpath project is now a working +prototype. +<ul> +<li>This prototype is interoperable with Sun's implementation v 1.4, +transferring object references, primitive types, narrow and wide strings, +arrays, structures and trees between these two platforms. +</li> +<li>The prototype provides interoperable support for the Abstract interface + and Value types. Those appear in 1.3, being a feature of CORBA 2.3. +</li> +<li>The remote exceptions are also transferred and handled as expected. +</li> +<li>The support for parsing stringified object references (IORs), both +Big and Little Endian encoded, is implemented. +</li> +<li>The redirection commands works, LOCATION_FORWARD_PERM changing the +target address until the application is restarted and LOCATION_FORWARD +redirecting for the current session only. +</li> +<li>Both Little and Big Endian encoded messages are accepted. The encoding +of the sent messages is the same as used in the stringified IOR reference +of that object or Big Endian, if no such data available. +</li> +<li>You can use both request-oriented (based on {@link org.omg.CORBA.Request} +and stream-oriented (based on {@link org.omg.CORBA.portable.ObjectImpl} +invocation models. The current release includes the working examples, +demonstrating the client-server communication using both methods. +</li> +<li>These examples also show, how to use the Classpath naming service. +</li> +<li>The IDL compiler is not yet written (and not even started), but as a + side effect of the required compatibility, the implementation seems +accepting the output of the Sun's idlj. +</li> +<li>The Portable Object Adapter is already released. For details on POA, +see the {@link org.omg.PortableServer} package.</li> +<li>We provide the implementation of the {@link org.omg.DynamicAny} +package. ORB returns the working DynAnyFactory that produces working +DynAny's as defined in OMG specification.</li> +<li>The Portable Interceptor is also complete. See +{@link org.omg.PortableInterceptor} package for details how to register +and use CORBA interceptors. +<li>All GNU Classpath classes in omg.org namespace are newly written using + the OMG .pdf document (Version 3.0.3, formal/04-03-12). +</li> +</ul> + + @author Audrius Meskauskas, Lithuania (AudriusA@Bioinformatics.org) +</body> +</html> + |
