[squeak-dev] Class var order in Monticello (bogus dirty packages)

Hi -
I have noticed several times that Monticello sometimes reports a
different order of class variables than the one that's in the image and
I think I finally found out what causes it. The problem seems to be that
the MCClassDefinition is constructed from a Set of class var names
(i.e., Delay classVarNames => a Set(#TimerEventLoop #SuspendedDelays
#TimingSemaphore #ActiveDelayStartTime #ActiveDelay #FinishedDelay
#ScheduledDelay #RunTimerEventLoop #AccessProtect) derived from the
class' classPool.
The thing is, the order in that class pool can differ. When you add or
remove class var names, the names can get shuffled around and there is
no telling what the exact enumeration order will be. Once the order is
different it's a real pain because Monticello will always report
differences but without a way to correct the issue.
I'm wondering what possible fixes might be. In particular considering
that reordering the class var names will mark any packages dirty for the
same reasons.
Any ideas?
Cheers,
- Andreas
