Please review this subset of transitions for FGCP. Is the
pending->:finish valid here?
start.to( :pending ) .on( :create ) # new instances do
not start automatically
pending.to( :stopped ) .automatically # after creation
they are in a stopped state
pending.to( :finish ) .on(:destroy) # after creation
they can be destroyed
stopped.to(:finish) .on( :destroy ) # only destroy
removes an instance, and it has to be stopped first
If 'pending' transitions to :stopped automatically, the user wouldn't
have a chance to action :destroy on it, so I suppose only the fourth
transition is possible. Should I remove pending->:finish?
What confused me is the following in ec2 driver:
pending.to( :running ) .automatically
pending.to( :stopping ) .on( :stop )
pending.to( :stopped ) .automatically
How can a state automatically transition to two opposite states, and at
the same time allowing a user to action on it?
Thanks,
Dies
