func FreeMemory ¶

func FreeMemory(iteration int)

FreeMemory calls debug.FreeOSMemory() every 10 loop iterations. This is very useful in tests that initialize a native state from a proto state inside a loop. Most commonly this happens in tests that make use of fuzzing. The reason is that fields of the native beacon state which are multi-value slices always create a slice of proper length for that field, even if the proto state's slice has a smaller length. Because the beacon state keeps a reference to the multi-value slice object, the multi-value slice is not garbage collected fast enough, leading to memory bloat. Freeing memory manually every 10 iterations keeps the in-use memory low. The tradeoff is longer test times.
