debugStats.py: No module named 'pynorm.extra.pipeparser' #60

Open honglei opened 2 years ago

In examples\python\debugStats.py

from pynorm.extra.pipeparser import PipeParser

The "debugstats.py" is an incomplete file that is not functional. I will add comments to that effect. It was supposed to provide an example of how to process the NORM debug output which can be (as a sort of "hack" approach) optionally redirected to a local "ProtoPipe" (Unix domain socket on Unix systems and named pipe on Windows) but it looks like the code it references was not ever added to the source code repository.

I plan to provide NORM API calls that can access the statistics that are output in the debug output since parsing the text debug log output is not a good practice.

function NormGetTxRate is missing in pynorm/session.py, users need a way to find out the status of sender. When sending files, NORM_TX_OBJECT_PURGED is never emitted, is it correct?
