[Fab-user] Error handling with @parallel decorator

[Ankur Agrawal]

I am trying to catch Abort exception. When I use fabric run(...) method, the host it tries to connect is not available and so it aborts with connect time out exception. I am not able to catch it. Following is a two different ways of code snippet-

First I try following  - 

class FabricException(Exception):
    pass

with settings(abort_exception = FabricException):

try:
    output = run(command)
except FabricException:
    print 'inside exception'
    LOG.debug("inside exception")
It didn't go in exception block. Instead it threw - 
NetworkError: Timed out trying to connect to pqaltsnas300.corp.intuit.net (tried 1 time)
Aborting.
SystemExit: 1

Then I try to continue even if exception - 

command  = 'ls -l'

with settings(warn_only = True):

      output = run(command)

Still it threw the same exception 

NetworkError: Timed out trying to connect to pqaltsnas300.corp.intuit.net (tried 1 time)

Aborting.

SystemExit: 1

Appreciate if somebody tell if I am missing anything ?

Thanks,

Ankur
