Notes on Error Discussion
OK... We've opened a bunch of ERs with "Error" type stuff in them. I've tried to compile the complete list below.
209227: Common Error Management System for COSMOS https://bugs.eclipse.org/bugs/show_bug.cgi?id=209227 see also: COSMOS Design 209227
209224: Error Management for DataCollection Framework https://bugs.eclipse.org/bugs/show_bug.cgi?id=209224
209242: Error Management for MDR interface to SML repository https://bugs.eclipse.org/bugs/show_bug.cgi?id=209242
(close 209242 and make part of 224)
209234: Error management for the contract between the UI and DataCollection https://bugs.eclipse.org/bugs/show_bug.cgi?id=209234 see also: COSMOS Design 209234
(close 209234 and make part of 224, UI part of 223)
208592: Error Handling - improve programming model https://bugs.eclipse.org/bugs/show_bug.cgi?id=208592
This is really error handling for the server components that drive the UI.
209223: Error Handling - client side https://bugs.eclipse.org/bugs/show_bug.cgi?id=209223
Proposed Course of Action
First, I'd like to check in the code that is attached to . This introduces the common COSMOS exception. We can, over the course of i8 & i9, refactor to have all of our exceptions extend this one.
Second: Close 242 and 234 as dupes of 224.
Third, Sheldon and team have prepared a design document on . I propose that we review this and close the ER prior to the architecture call on 20-Dec-07 via e-mail on COSMOS-dev.
I'd propose that we review and close the forthcoming design of [209223 prior to the architecture call on 20-Dec-07 via e-mail on COSMOS-dev.
I'd propose that we review and close the forthcoming design of  prior to the architecture call on 20-Dec-07 via e-mail on COSMOS-dev.
Errors vs. Logging....
There was some discussion/confusion that COSMOS Design 209227 was or was not going to cover our logging strategy. In prep for this discussion, I went back over some of my notes and trolled around on the wiki to try and assemble where I think we are. The net is, we wanted to keep the logging strategy related, but separate from, the error strategy. We established a page to capture our logging requirements COSMOS internal logging use cases. The intent was to use these use cases to open up the necessary ERs.
Looking at this page, we clearly have some work that needs to be done. Given that we are getting to the point where we need to start producing logs, we may want to ensure we get a good cut of this work done in i9.
