CORBA in GlassFish Server Open Source Edition version 3.1
ORB Feature List for GlassFish Server Open Source Edition 3.1
A list version of the feature list is also available.
Note that all of the ORB features for the GF 3.1 release are linked to issue 11939.
| Feature ID | Desired Improvement | Priority | Comments | Description | Current Plan |
|---|---|---|---|---|---|
| IIOP-1 | Remove glassfish-corba-asm | P2 | Only change is to update CORBA bundles and CORBA renaming | 11940 | No: dropped from plan for GF 3.1 |
| IIOP-2 | Improve CORBA Testing | P2 | Some parts support P1 features (e.g. IIOP-9). More work to do on Hudson integration. | CorbaTesting 11941 | No |
| IIOP-3 | CORBA monitoring work | P3 | Finish applying Gmbal to ORB; possibly some more integration with GF monitoring | CorbaMonitoring 11942 | No |
| IIOP-4 | CORBA performance work | P3 | Would like to improve copyobject. Also ORB locking contention issues from bug 6933754 (Ericsson escalation). | 3455 | Yes on Ericsson; maybe on copyobject if time permits |
| IIOP-5 | New Connection Caches | P2 | 4074 ConnectionCache | No for 3.1 | |
| IIOP-6 | FindBugs work | P2 | Still 276 issues (down from ~400 in GFv3) | 4084 | Fix high priority FB items for GF 3.1. |
| IIOP-7 | Remove remaining code in ORB that is not used in GF | P3 | Work on IIOP-12 has reduced the ORB size significantly. All of the activation code has now been removed as well. | N/A | DONE (for 3.1; re-doing exception wrappers will also reduce code size) |
| IIOP-8 | IIOP FOLB | P1 | Just get the old GFv2 code running in GF 3.1. No changes in ORB code. | IIOPFolb 11944 | Yes, required for GF 3.1.0. |
| IIOP-9 | IIOP FOLB improve dev testing | P1 | Need dev tests for IIOP FOLB: none today that run at the app server level (have unit tests in ORB) | IIOPFolb 11945 | Yes. Required for IIOP-8 |
| IIOP-10 | IIOP FOLB with CSIv2 | P1 | Will revisit CSIv2 code split between ORB and GF | 2791 | CSIv2Notes No: will not address this for GF 3.1 |
| IIOP-11 | Remove scheme-based exception wrappers | P3 | Get rid of Jscheme, simplify ORB logging system | ORBExceptions | Yes: DONE |
| IIOP-12 | Timing and tracing improvements | P1 | Want better field support capability. New tracing facility based on annotations and bytecode instrumentation | CorbaTracing 11943 | Yes, New tracing facility is nearly complete. DONE for MS4. |
| IIOP-13 | Add object reference categorization | P2 | Wanted by transactions team | 2788 | No (dropped from plan 9/1/10) |
| IIOP-14 | Move IIOP parts of CSIv2 to ORB | P2 | Useful for IIOP-10 | 11114 | No for GF 3.1 |

Notes:
- IIOP-6 and IIOP-7 are not included in the task breakdown. They will be addressed for 3.1 if time permits.
- IIOP-11 will probably not be done for 3.1, as there is not enough time for it.
- All time estimates are unloaded. To allow for meetings, interminable planning sessions, and sustaining effort, all estimates will be scheduled with a 1.5 multiplier (that is, assume 67% of work time is available for actual execution of the above tasks).
- Items that are complete get a 0 time estimate
