upload file and estimation time

[whatazor]

Hi all,
unseccsefully, I try to analyze this problem. If I can only work on
the client size, how can I create a module that calculate the upload
time of a file, so the time for finish it? i can start with ftp
protocol and after extend this logic for my requirements.

thx

All you need to to is to

- count the number of bytes to transfer, U

- count the bytes already transfered, u

- measure the time since the upload, t



Then the ETA is

eta = (u / t) * (U - u)

Using the ftp-lib, you best pass a file-wrapper that overload the
read-method to accumulate the read bytes to yield u.
