Summary
I always thought weak maps would hold weak references, which seemed obvious to me
So I tested it out, and either my test script is wrong, or the weak maps are just broken (and never even worked?)
If weak maps don’t hold weak references, please update the docs to say so
Related? : Classes never garbage collected?
Steps to Reproduce
unique_object := class<unique>:
MemoryIntensiveArrays : [][]float
test_weak_maps := class(creative_device):
var SomeWeakMap : weak_map(unique_object, logic) = map{}
# var SomeWeakMap : [unique_object]logic = map{}
OnBegin<override>()<suspends>:void=
HugeFloatArray := for(__ := 0..1000000) {0.123456789} # Should be passed by copy as every array do
for(I := 1..10000):
NewObject := unique_object:
MemoryIntensiveArrays := array:
HugeFloatArray
HugeFloatArray
HugeFloatArray
HugeFloatArray
HugeFloatArray
HugeFloatArray
HugeFloatArray
HugeFloatArray
HugeFloatArray
HugeFloatArray
option{set SomeWeakMap[NewObject] = true}
Print("Itration({I})")
Sleep(0.0)
# NewObject should be removed by garbage collector here?
Expected Result
After 300 iterations (10s) both map or weak_map cause a server crash
But it should only happen with maps (or in a transactional context?), memory should be freed up whenever the reference to the weak map key is not held anymore
Tried the same thing over the course of 5min (in case garbage collector would not happen instantly) and the results are the same
Observed Result
Weak maps behave exactly the same as normal maps memory wise…
