Re: [Fab-user] Summarize results from parallel execution

[Vineet Gupta]

Nevermind. Moving roles to the bottom with task on top does the trick.

@fabapi.task

@fabapi.parallel

@fabapi.roles('app')

def status():

   """Show apache status"""

   ...

Thanks,

@parallel and @roles does not seem to play nice together. My tasks are always executing in serial order, unless I am setting env.parallel = True. This is how I am decorating my tasks -

@fabapi.roles('app')

@fabapi.task

@fabapi.parallel

def status():

   """Show app status"""

   ...

Any suggestions?

Thanks,

Vineet

Thanks a bunch. Exactly what I needed. I didn't realize how execute() returns value from all parallel execution as dictionary. 

Much appreciated.

I added the answer to this, as an FAQ in the docs. It comes up a lot.
It's here now:

(which should link to
