[Fab-user] How to use the env option "command_timeout"?

[Anubhav Yadav]

I have rabbitmq installed on one of my servers, and I log into it and issue
the command :

"service rabbitmq stop"

Which is followed by:

"service rabbitmq start"

Now sometimes it so happens that the service will not stop/start for a long
time. So I will need to abort the service (by sending a keyboard interrupt
^C) and run the command again.

I want to replicate the same using fabric. I read the docs, and it said
there is an option called command_timeout. Not much documentation is
available about it. Here is my code snippet that I am trying to use:

def restartRabbitMQ():
flag1 = True
flag2 = True
with settings(command_timeout=15, warn_only=True):
while flag1:
result = sudo("service rabbitmq-server stop")
if result.failed:
continue
flag1 = False
while flag2:
result = sudo("service rabbitmq-server start")
if result.failed:
continue
flag2 = False

However, this command will be stuck till unless rabbitmq starts/stops
itself or there is an error starting/stopping rabbitmq. command_timeout
seems to have no effect whatsoever.

Any help here?
