I don't want to flog a dead horse, but...

Do we document the correct approach anywhere easily visible?  When moving code between packages when that code is needed, the correct way is to...

1. Commit the package to which the code is moving, /not/ committing the package from which it has moved yet
2. Commit an update configuration 
3. Commit the package from which the code has moved

Hence on update the package to which the code is moving is loaded first, leaving the other package dirty but the code still present, and then the package from which the code has moved is loaded, leaving the code in place at all times.

This is simple and perhaps non-obvious.  We need to have this, plus similar verbiage about delegate system changes, documented and visible to our users.


Best,
Marcel

Hi All,

I went ahead and removed update-nice.422 from the Trunk. The only
difference between update-nice.422 and update-bf.422 was that the former
included Morphic-mt.1350 while the latter referenced Morphic-dtl.1374.
This was a significant difference, because after loading Morphic-mt.1350,
Object >> #currentHand and friends were temporarily removed from the
image, which somehow resulted in the removal of the UI process without an
emergency evaluator ever appearing. I think that's something to be
investigated.

After this change, I could successfully update the latest Trunk image
available on files.squeak.org.

I could do this removal only because the members of the Squeak Oversight
Board group on source.squeak.org have not been updated since 2016. For the
very same reason, Nicolas couldn't have done this change.
