yassh
Yassh is a python library used to run asynchronous, dependent remote and local tasks.
Usage
import logging
from yassh import Reactor, RemoteRun, RemoteConfiguration, LocalRun
logging.basicConfig(level=logging.DEBUG)
# Create a remote ; only host parameter is mandatory
remote = RemoteConfiguration(host='localhost', username='user')
# ssh_config(5) options can be set in RemoteConfiguration object
remote.set('Compression', 'yes')
remote.set('CompressionLevel', '9')
r = Reactor()
c1 = RemoteRun(r, remote, 'sleep 5')
c2 = LocalRun(r, 'echo ok')
c3 = RemoteRun(r, remote, 'echo "finished" && sleep 1')
def start_c2(run):
# Start cmd2 when cmd1 complete successfully
if run.result == 0:
c2.start()
c1.register_exit_monitor(start_c2)
def start_c3(run):
# Start cmd3 when cmd2 complete
c3.start()
c2.register_monitor(u'ok', start_c3)
def on_c3_finished(run):
# Print dummy message when c3 is near terminaison
print('c3 almost finished')
c3.register_monitor(u'finished', on_c3_finished)
# Start first task
c1.start()
# Infinite
timeout = -1
while r.run(timeout) > 0:
pass
