Issues:

How to proceed when a module dosen't behave well (e.g. LV trip)

note : Requires modification to DSP code to get histogramming to continue when errors are encountered!

Modifies IS TestData to include list of bad modules, to be added to by API
1. is this sufficient for all scenarios?
2. Does this need to be done on a per-test basis? Current status probably insufficient.
API produces dummy RawScanResult with some sort of status info
1. a bit nasty? (assuming something like solution (1) is used above!)

Add bool memebers expectRawResult, expectFitResult, expectTestResult (and archiveMe?) to TestData in IS (and to TestRequest?).
What to do if dont expect result, but get one?
- Do your stuff anyway - what have you to lose!
What to do if expect result
- Watch IS to see if module is marked as bad
- If it is bad, dont do dependant actions (e.g. remove analysis of test if final Raw is not produced)
- Otherwise continue as usual.
Behavour of Archiving*
- Archive control objects with list of bad.
- Various implications for DB structure need to be investigated.

General philosophy is that GUI should be farily distinct from the nasty low-level stuff.
If two or more GUIs are running (as was the case in Oxford yesterday), could cause synch problems.
What does GUI do if services are busy() Analysis:
Data is really shared between many processes.
Needs some sort of idea of whether to expect data of various types
Some data will be e.g. file cache of retrieved data requested and used by GUI.

To me it seems that clean-up on end of run is the best option.
- CalibrationController refuses to do EOR until Analysis and Archiving are done
- CalibrationController clears scratch on EOR.
  - problem with circular dependancies in interfaces.

Largely Dave and Alan to discuss. Archiving to move to CondDB? in Release 4 - work required here.

Is it worth having an interrim solution (I'd say yes!)
Is current ArchivingService interface sufficient?
Awkwark bug in IS means work-around is required for retrieval of control objects. Fixed in online 00-21-02. Alan can do work-around until that is in use.
