In a recent code review, I had modified the following code:
_freeSegments.AddOrUpdate(memoryDataForPointer.SizeInBytes, x =>
{
var newQueue = new ConcurrentQueue<AllocatedMemoryData>>();
newQueue.Enqueue(memoryDataForPointer);
return newQueue;
}, (x, queue) =>
{
queue.Enqueue(memoryDataForPointer);
return queue;
});
Into this code:
var q = _freeSegments.GetOrAdd(memoryDataForPointer.SizeInBytes,
size => new ConcurrentQueue<AllocatedMemoryData>());
q.Enqueue(memoryDataForPointer);
Can you tell me why?
