Long delay after loading 10301+10302

Nicolas Cellier
My image got unresponsive for a long time just at the end of load,
showing the dialog
    2 new update file(s) processed
Attaching gdb to the process and call printAllStacks() gave me:

2033300892 WeakIdentityKeyDictionary>scanForNil:
2033132772 WeakKeyDictionary>rehash
2033128872 WeakKeyDictionary>finalizeValues
2033128780 >finalizationProcess
2033128688 SequenceableCollection>do:
2033128580 >finalizationProcess
2033128488 Semaphore>critical:ifError:
2033128396 BlockClosure>on:do:

2017849452 >finalizationProcess
2017849360 >restartFinalizationProcess
2017849544 BlockClosure>newProcess

And this loop did last very long...
Of course, this is a high priority process, so pressing ALT+. won't
give me much feedback.
Hmm, a high priority process taking CPU for a long time, that smells...

Re: Long delay after loading 10301+10302

Stéphane Ducasse
Hi nicolas

this is strange because 10301 was a bunch for collection test and a  
merge fix for traits.
then the 302 were mainly your fixes on numbers. So I have no idea about
what is happening.

Did that happened during 10303 because there the changes were the one  
below + InputSensor initalization.

Re: Long delay after loading 10301+10302

Nicolas Cellier
indeed, I think it's got nothing to do with change contents per se.
It must be kind of bad luck with finalizationProcess...
See also http://bugs.squeak.org/view.php?id=7350 : WeakRegistry
behaves as bad as WeakSet.
It probably has more to do with bug encountered with loadOBalpha. This
one was reproduceable: maybe I should not have pushed a workaround
that soon ;)

yes probably
may be we could have a cs to revert the fixaround
