 This is when the image concept get counterproductive if you didn't
 commit all your code changes. :-/

 Hi Esteban,

 Can you reproduce it with a fresh image?

The image freezed, but fortunately with a LOT of patience I was able
to type a character every once in a while. So I could write an
smalltalk expression that after being evaluated opened a debugger and
caused the image to get responsive again.

The expression was a last resort in order to cause another error
that could give me the control back.

VOLazyProxy allInstances do: [:each | each become: String new ]

It worked.

 Btw I am saving my image now each hour or so...

I'm not used to do it, I trust in the changes file, the problem is
that I saved the image with the offending proxy.

The problem was a modification of a document in a collection. I did a
mongo upsert that changed it, and apparently Voyage didn't know how to
handle it.

Regards!

[Pharo-users] Voyage: image freeze/VOMongoError: Lazy reference not found

2013-08-15 Thread Sabine Knöfel 
Hi Esteban,

sorry but I need your help again.

I succeeded in re-writing all my code to use voyage and can save all my
model now. Great!

Now I was experimenting with it and I have an Image freeze which should not
occur in production;-).

Situation:

I created one Person with two trips. Trip points back to its person.
After writing it into mongo, I delete one trip from mongo manually (I use
rockmongo, great tool).

So in the database, I have now
1) one Person which points to two trips
2) one trip (the other was deleted)

Now, I do:
Person selectAll first trips

and the image freezes.

Sometimes, I find in the DebugLog: 
VOMongoError: Lazy reference not found RKATrip: OID(103475906)

This is correct ;-)

I did also try with enableMissingContent but did not work.
http://forum.world.st/Voyage-GC-collecting-random-objects-td4668438.html

Sure, normally, we do not manipulate the database manually.
But I want to be sure that the image does not freeze if this occurs

How can I solve this?

regards 
Sabine
