05/05/2022, 4:51 PMdoes anyone know on an arrayEach with threads, do the variables created outside the thread but used inside get duplicated within each thread? Seeing a bit of a memory issue when i use the threaded arrayEach, it was working but until i added a large variable that was needed to be used inside the loop.

05/05/2022, 5:55 PMWhile CFThread on Adobe historically has duplicated all attributes passed in, I'm not aware of any such behavior in arrayEach()

05/05/2022, 5:55 PMDo you have code to repro this?

05/05/2022, 5:55 PMGenerally speaking, when you do
Copy code
outsideVar = 'foo';
[1,2].each( ()=>{ echo(outsideVar) }, true )outsideVarg

Copy code
outsideVar = { "brad" : "wood" };
[1].each( ()=>{ outsideVar.curt='gratz'; }, true )
dump(outsideVar)bdw429s
05/05/2022, 6:37 PMChanges inside the threaded calls are directly modifying the original struct
bdw429s
05/05/2022, 6:37 PMI'll add there can be a lot of overhead for very large arrays in parallel, especially if the processing on each item is very small
bdw429s
05/05/2022, 6:38 PMAre you sure the only thing that changed was the size of the struct?
