Fabio's stack looks like if Object >> #currentHand gets lost at some point during the update. :-/

Hi all,

A recent change causes trunk updates to freeze for some reason. I don't know which change is causing the problem, but I would appreciate if someone could like into this. Error log is below and indicates that there's at least an MNU.

Thanks, Fabio

​Updated from 17529 -> 17560​ no problem.

(BTW: would be nice if we could copy text out of a notifier)

Ok here it might be: The error is with "currentWorld". Se this stack:

It seems something is wrong with #handleFatalDrawingError (19), but while this might be the case, the root cause here is in

line 41 MorphicToolBuilder(Object)>>doesNotUnderstand: #currentWorld (and by extent, stemming from MorphicToolBuilder>>buildPluggableWindow:) Why is it trying to spawn the window? Line 48 gives a clue (Debugger>>openNotifierContents:label:) which might be due to me (And possibly Fabio) having changes in the image and us being notified about possible merges…

I'll look into it…

Best regards -Tobi

Fabio's stack looks like if Object >> #currentHand gets lost at some point during the update. :-/

Hi, there.

Works for me when updating from 17535 to 17560.

Fabio's stack looks like if Object >> #currentHand gets lost at some point during the update. :-/

???It was moved from Kernel to Morphic in Kernel-dtl.1123 and Morphic-dtl.1362.

Kernel comes before Morphic in our update map, which would indeed lead to the temporal removal of the method.

However, MCReorganizationPreloader took care of it in my image. Object>>currentHand is in changeset mcPreload10, along with currentEvent and currentWorld.

I don't know why MCReorganizationPreloader would not have caught this in another image?

• Bert -???

It looks like I should have added one or two update maps make sure that Kernel-dtl.1123 and Morphic-dtl.1362 get loaded at the same time.

I cannot really look at it until about 10 hours from now, so hopefully it is not causing too much disruption.

​No, we specifically introduced MCReorganizationPreloader to avoid having to manually resolve moves with separate update maps.

I'm sure Tobias will figure it out, we're working on it.

​Yes, found the problem. Nicolas updated only the Kernel package in update map 422, but not the Morphic package. That means the two are not loaded in the same update, meaning the methods get actually removed.

421: Kernel-cmm.1114, Morphic-mt.1350 422: Kernel-nice.1127, Morphic-mt.1350 <= Kernel-dtl.1123 gets loaded but not Morphic-dtl.1362 423: Kernel-nice.1128, Morphic-dtl.1374

I just replaced the 422 update map. Should be fixed.

Thanks for getting me off the hook :-)

​Hehe, the only thing you could have done wrong would have been publishing the ​Kernel package before the Morphic one. That would have bit someone who updated right in that minute before the Morphic package was up.

But you did it right, Morphic was up first, so no problem at all :)
