> My original requirement was for a method that would tell me how much physical memory is occupied by an array's buffers. I would call this something like `get_buffer_memory_size`. > Others than asked for additional functionality to determine how much of the memory is actually being used for data. I suppose I would call this something like `get_buffer_utitilized_size`. > Then there is the idea of an additional method that returns the total memory used by an array, including the buffers and other attributes. I'm not sure why we need this, personally, but if we do then I suppose `get_array_memory_size` would work? 1. Changed to `get_buffer_memory_size` and `get_array_memory_size`. Since they correspond to that. > ... I'm not sure why we need this, personally... I am using this for memory estimation and eviction calculation in the db that I am writing. That is kind of important since these are also giving accurate results about what is resident. plus this is how servo calculates actual memory usage. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
