Re: [Fab-user] api.run: fatal errors versus exceptions

[Steve Hajducko]

( Sorry Paul for emailing twice, forgot to hit reply to all )

Why try and do it this way?

The tutorial lists a much simpler way:

with settings(warn_only=True):
       ThisRet = fabric.api.run(CmdString)
   if ThisRet.failed and not confirm("Tests failed. Continue anyway?"):
       abort("Aborting at user request.")

You don't need to use exception handling for these because fabric
already handles the exceptions and passes an object back to you that
you can handle and do what you want with.
