New log system :
we use the logging module now. There are three levels for log messages :
- info : give basic information about what vifibnet is doing
- debug : display internal work of the script (finished action, detailed
information about tunnels, etc... )
- trace : for intensive debug, display configuration, arguments given to
processes, all information pertinent to debug but not required
mot of the time
Additionally, warning, error and exception can be used.
Note : logging.exception prints informations similar to pdb.set_trace()
info, which is pretty heavy, so for exception we expect ( for
instance, connection problems to the registry ), one can print the
exception as warning. ( see db.refresh() ).
Vifibnet is a daemon setting up a resilient virtual private network over the
internet
