Re: CORBA again

I started working on an implementation using ORBit, but the real-world got in the way, and I haven't made much progress since, but I will tell you what I know: A) The ORBit DII stuff had a bug or two that I submitted patches for, and now exist at least in the CVS version. DII is a must-have really. B) Of course, even with DII we need to have some way of correctly building the DII calls (i.e. we still need to know the proper types of each argument) and marshalling between the PHP variables and CORBA object operations. There are at least three ways of doing this 1. have the IDL available in some directory, parse it ourselves, and construct the Argument lists from this parsed IDL. This is the way the current loosely typed languages (i.e. Perl) integrate with ORBit. 2. Use an Interface Repository (IR) to grab the interface information dynamically. This is much more elegant, but unfortunately ORBit's IR is in an indeterminant state. This is not necessarily a big deal - ORBit is only providing the client-side ORB - we can assume that the Objects we are trying to access have registered with an IR - and this IR could be from another ORB. 3. Use some proprietary file format that describes the types of method arguments without all of the other IDL baggage, and parse this simplified file to get the method argument types. 4. just thought of another - we could use some structure in the PHP script itself to define the function variables more prescisely. C) Finding the object we want to use is also important, so integrating the naming service is important. Anyway, I got some rough code worked up, but got stalled at (B) trying to decide what to do. (2) is ideal, but we probably also want a fallback. I was designing it so that you could set an IDL repository directory in php.ini, and was going to pull the parsing code from the ORBit-Perl, and use that to save some work. If anyone is interested in helping, or seeing what I did, let me know. It is pretty rough, doesn't work at all, and might just be the ravings of a lunatic. I was planning on picking it up again this week and hacking on it. Does anyone have a preference for the different methods of grabbing the method argument types? I am planning on going with (2), with (1) as a fallback.
