Finding instances of old (removed) classes
 
|
I remember I once saw a script to find all instances whose class is an old class version.
I cannot iterate over the class history because the old classes are no longer in there. But I do encounter some instances of those old classes and I want to sweep the repository to detect all such instances. Does anyone still have that script? thanks!

I don’t have the script but it would involve (Metaclass3 allInstances , Metaclass allInstances).

I may be running into this too.
Is this the old script you had in mind: http://forum.world.st/instances-of-old-class-versions-td4100977.html ?

I think the actual script was in this message[1].

Thanks Dale.
I've now got the list of orphaned classes and list of references to each of the orphan classes. How do I migrate them to the newer/current versions of the classes? Is it just System abort. orphanedClasses do:[:orphanClass | orphanClass migrateTo: (Smalltalk at: orphanClass name)] System commit. or something more? Paul

No that won't work. Its #migrateInstancesTo: rather than #migrateTo: Several of the references are to GsNMethods in the orphan classes. I think. If I migrate will they also be taken care of?

Paul,
I'd like to know a little bit more about what you are trying to accomplish ... If I assume that the references to the orphaned classes are instances of the orphaned class then you will want to migrate those instances to the new version of the class. If those references are not from instances of the orphaned class - a direct reference to the orphaned class (as a key in a dictionary or something similar) then migration will not solve your problem ... you will have to do a findAllReferencePathsToObject .... and find clean up the references. For instance migration you should do some similar to GsDeployer>>doBulkMigrate: where the `classList` is your list of orphaned classes ..

The GsNMethods in the orphaned class's method dictionary are not keeping hte orphaned class alive, but they will go away when the orphaned class is eventually garbage collected ...

I'm not sure. Exploring, I guess.
I think I have some instances that are exhibiting old behavior. So I'm trying to clean up orphaned classes to see if that fixes the instances behavior problems. But it could also be a different bug I haven't found yet.

Okay then using the GsDeployer-style method, collect instances for each of your orphaned classes ... those with empty instance lists have class reference issues ... those with non-empty instance lists can be migrated ala GsDeployer-style method... If you've already cleaned the known spots up,m then those classes with reference issues can be resolved by finding all reference paths ... Mariano and I went through a similar dance several weeks ago, and I published a gist with the tode shell script that collected info on some "orphaned classes"[1] and I then produced an analysis based on using the script[2] ... at the end of the analysis I used the `./bug --references` to track down the reference to some of the orphaned classes ... Slightly different scenario, but the `--references`, `--instances`, `--gc`, and `--reclaim` options might be interesting or useful in your own little analysis script ...
