Hi,
i've implemented paramiko library to rdiff-backup code. If someone is
interested in I changed only two files: SetConnections.py and Main.py.
Here is some code:
# SetConnections.py modifications
import paramiko
import new
__cmd_schema = '%s'
# ......
# init_connection() function
# Remove .__del__ method from BufferedFile. This can broke thread
# and print some nasty exceptions at the end of rdiff-backup
# working.
paramiko.file.BufferedFile.__del__ = new.instancemethod(
lambda x: None,
None,
paramiko.file.BufferedFile
)
full_hostname = remote_cmd
port = 22
username, hostname = full_hostname.split('@')
if hostname.find(':') > 0:
hostname, port = hostname.split(':')
trans = paramiko.Transport((hostname, int(port)))
trans.connect(username=username, password='yourpassword')
chan = trans.open_channel("session")
command = 'rdiff-backup --server'
chan.exec_command(command)
stdin = chan.makefile('w')
stdout = chan.makefile()
conn_number = len(Globals.connections)
conn = connection.PipeConnection(stdout, stdin, conn_number)
Paramiko channel have makefile() function wich is simulating pipe similar to
popen2(). The second modification is some cleanup code for paramiko threads:
# Main.py
# cleanup() function
# join paramiko threads
from paramiko.transport import _active_threads
for tobj in _active_threads:
tobj.stop_thread()
tobj.join()
And this is all. I've tested it on Windows and Linux and it's working fine.
Paramiko is a little slower than ssh client on LInux.
Now i want to make some more modifications in code (for example reading
login/password from config file and GUI) so publishing paramiko connection
code now is a good idea ;-)
Modified files u can find here: http://pako.overflow.pl/trash/rdiff-backup/
Cheers!
