NativeBoost: Regenerate Native Code

by Sean P. DeNigris

How do I tell NativeBoost to regenerate all naive code for a class e.g. after changing the implementation of #nbCallingConvention? N.B. to NativeBoost newbies like myself, this is a *huge* potential pitfall that's difficult to diagnose. I was thinking, "well, I changed the calling convention and the vm is still crashing, so that can't be the problem" not realizing that the callouts never picked up the change ----- Cheers, Sean -- View this message in context: http://forum.world.st/NativeBoost-Regenerate-Native-Code-tp4725651.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

The thing about being able to load a graph I wrote above has also the constraint that all loaded objects that are still participating in the active graph need to be in the cache. But then the cache is a weak dictionary meaning that all objects leaving the active graph are removed from the cache (well at GC time, I think) I did a small test some time ago, and it confirmed that the cache is subject to garbage collection.

Re: [Pharo-users] Mongo cache vs database objects

by Sabine KnÃ¶fel

Hi Norbert, thank you very much for the clarification. I had to read it several times but now I understand and I know what to change in my model for this (something with references to objects which have been deleted by the user). Perhaps your answer is also interesting for the documentation of Johan.

Mongo cache vs database objects

by Sabine KnÃ¶fel

Hi Esteban, all, I work with mongo daily an it works fine, I am very happy with it. As you told me, with >>VORepository current reset. I can force re loading all objects from database and resetting the cache completely. This is helpful for development eg. after changing the magritte descriptions. My question: Is there a possibility to make a query and tell voyage that THIS query should be done within the database and NOT within the cached objets? And that all objects and the child objects from this query are loaded freshly from database into the cache. My concrete situation: I want that if the user logs in, his objects are loaded from database and NOT from cache. This means the person, his trips etc. And the question coming along with this: How long does the cache keeps objects/when are they reseted (except the >>VORepository current reset)? If I would never take a new image and never make a reset, would all objects remain in the image (and the database objects wold never be read)? In this case what about the size of the image?
