JSAGA

Dear Developers,

We tried to monitor progress of copy tasks (via FILE_COPY_PROGRESS metric callback),
and it works in most cases (between the five protocols of our primary interest), as shown below:

Progress change indication
src/dest  http https sftp gsiftp srm
http      -    -     OK   OK     OK
https     -    -     OK   OK     OK
sftp      -    -     OK   ?      ?
gsiftp    -    -     OK   ?      OK
srm       -    -     OK   OK     OK

(1) However, in sftp->gsiftp and sftp->srm directions, we don't get progress change callbacks,
though - I guess - jSaga does the "tunneling" of data from source to target. With
other protocols progress monitoring works for the same source or target, respectively,
so I don't know why it does not work in these cases (or I should do something different?).

(2) gsiftp->gsiftp probably does third-party transfer. Is there any way in this case to
get progress information from jSaga about these tasks?

Thank you, Akos Hajnal
