Voyage: image freeze/VOMongoError: Lazy reference not found

by Sabine KnÃ¶fel

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 ########################################### with this filein you can reproduce it easily ########################################### Object subclass: #Person instanceVariableNames: 'trips lastName' classVariableNames: '' poolDictionaries: '' category: 'RKA24-Demo'! !Person methodsFor: 'accessing' stamp: 'sabineknoefel 8/15/2013 10:02'! lastName ^ lastName! ! !Person methodsFor: 'accessing' stamp: 'sabineknoefel 8/15/2013 10:02'! lastName: anObject lastName := anObject! ! !Person methodsFor: 'accessing' stamp: 'sabineknoefel 8/15/2013 10:02'! trips ^ trips! ! !Person methodsFor: 'accessing' stamp: 'sabineknoefel 8/15/2013 10:02'! trips: anObject trips := anObject! !

Re: [Pharo-users] Voyage: Circular references

by Sabine KnÃ¶fel

Hi Esteban, this would be fine! A few minutes ago, I wrote another thread here with some questions about memory. And after sending it now I got the following message from pharo "Space is low Warning! Pharo is almost out of memory. ...." So, if you could tell something about memory usage in your post with voyage this would be helpful Regards Sabine On Wed, Aug 14, 2013 at 11:52 AM, EstebanLM [via Smalltalk] < ml-node+s1294792n4703610h5(a)n4.nabble.com> wrote: > > On Aug 13, 2013, at 4:58 PM, Sabine KnÃ¶fel <[hidden email]<http://user/SendEmail.jtp?type=node&node=4703610&i=0>> > wrote: > > > Hi Esteban, > > > > thanks, this works fine now! > > > > You also answered my next question how to define an attribute as > transient > > -> with VOMongoTransientDescription :) > > > > Your blog posts > > http://smallworks.com.ar/web/blog?_k=c9RiCz1d5w-0XSbp > > are very helpful to start. > > cool :) > > > > > Do you have more information/documentation for voyage? > > not really, I will write a new post with all the information from this > thread, I think that can be useful for others :) > > cheers, > Esteban > > > > > Regards > > Sabine > > > > > > > > > > > > -- > > View this message in context: > http://forum.world.st/Voyage-Circular-references-tp4691940p4703493.html > > > Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com. > > > > > > > ------------------------------ > If you reply to this email, your message will be added to the discussion > below: > http://forum.world.st/Voyage-Circular-references-tp4691940p4703610.html > To unsubscribe from Voyage: Circular references, click here<http://forum.world.st/template/NamlServlet.jtp?macro=unsubscribe_by_code&no…> > . > NAML<http://forum.world.st/template/NamlServlet.jtp?macro=macro_viewer&id=instan…> > -- View this message in context: http://forum.world.st/Voyage-Circular-references-tp4691940p4703617.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] Voyage: save Date, get back DateAndTime - bug?

by Esteban Lorenzano

Hi Sabine, that's a known issue... from mongodb :) Mongo does not recognize between Date and DateAndTime, so even if you commit a Date, you will have back a DateAndTime. Only way I know to deal with that is by transforming it manually :( cheers, Esteban On Aug 14, 2013, at 11:44 AM, Sabine KnÃ¶fel <sabine.knoefel(a)gmail.com> wrote: > Hi Esteban, All, > > when saving an instance of *Date* within an attribute with voyage into Mongo > and doing > > VOMongoRepository allInstancesDo: #reset. > > then loading the object back from database, I get an inst of *DateAndTime* > in this attribute. > > Of course, I can "hack" by the tools you gave me :-) it but I ask myself if > this is a bug or by intent. > > Regards > Sabine > > > > > > -- > View this message in context: http://forum.world.st/Voyage-save-Date-get-back-DateAndTime-bug-tp4703601.h… > Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com. >

Voyage: proxy/memory questions

by Sabine KnÃ¶fel

Hi Esteban, All, could you please give me some little explanations about the mechanism between the database and the objects in my image: 1) I see that after VOMongoRepository allInstancesDo: #reset. all objects are re-loaded from mongo, is this correct? 2) How can I ask voyage to only re-load a certain object from Database and not all objects 3) How can I ask voyage to only re-load all objects from a certain class 4) what about the image size and the memory? When are the loaded instances thrown away? Is this done automatically? Do I have to do something for this? How to avoid my image getting bigger and bigger? I ask because since working with voyage, I had several times an image which became slower and slower and at the end freezed. I assume that I make something wrong here. And, as a last point, after VOMongoRepository allInstancesDo: #reset. saving an Instance from inspector (or from my application) which was opened before the #reset will be saved as a new object in mongo. So it duplicates the objects in the database. Is this ok?
