(engine dev thinky stuff) Trying to think of a reason I shouldn't have an asset cache that gives out strong refs to loaded assets, but itself only stores a WeakReference (so that if nothing references a given asset it can just be garbage collected automatically...)

Flutter Memory Management: Leaks, Profiling & Production Monitoring
Your App Feels Slow After Ten Minutes. That Is Not a Performance Problem. That Is a Memory Leak.

Es gibt WeakReference in PHP. 😭
2/2 … PHP-Arrays werden entsprechend aktualisiert.
Dann habe ich Interfaces und Traits für Retainables, Nodes und Node Data. Das ermöglicht Trees, wo die einzelnen Nodes auf ihren Supernode aka Parent Node verweisen können, ohne Circular References, die von PHPs Garbage Collector aufgebrochen … 2/3

The other thing I loved back then was after loading before gameplay started I would do (and I forget the exact type names here, sorry)
WeakReference gcTracker; // member of the renderer, I think?
gcTracker = new object()
And before every present if it was null, I cleared to purple and remade it
WeakReference gcTracker; // member of the renderer, I think?
gcTracker = new object()
And before every present if it was null, I cleared to purple and remade it

How would you write a test to verify that a WeakReference implementation actually does free its memory at some point?

this approach could lead to a memory leak! If the view or Activity is destroyed while the Runnable is still posted and holding a reference to it, a memory leak can occur. You might need to clean up on this Runnable or wrap the reference in a WeakReference 🤙

Is your WeakReference implementation manually managing its memory?
Could you instrument the pieces of code which deals with deallocating memory, perhaps providing a hook (possibly only used within tests)?

But yeah, my trick was to have, in my renderer (and it's been a minute so ignore that the syntax is all wrong)
WeakReference gcWatcher = new object();
and before present, if gcWatcher was null, I cleared the screen to purple and re-created it so I could visually see the GC happening
WeakReference gcWatcher = new object();

Le grand cycle de la vie (d’une variable)
En PHP, pas besoin de se préoccuper de l’allocation mémoire, le ZendEngine gère tout ça pour vous ! Malgré tout, lorsque vous exécutez des processus longs (cron, workers…), il est parfois (trop) facile de consommer beaucoup (trop) de mémoire sans s’en rendre compte… *Garbage collection*, références cycliques, *copy on write*, *WeakReference*… voici un rapide tour d’horizon des pièges et outils à connaître pour optimiser la gestion mémoire de vos programmes.
