The "Waiter" class is now deprecated. A "wait" method is used instead. The new method is located at "kamaki.clients" and has this signature: wait( poll method, poll method params, stop method, delay=1, timeout=100, caller callback method=None) The poll method is provided by the caller and is typically the "get_details" method of each API client. The "poll method params" is a list of parameters for the polling method, typically just the item id (i.e., server_id, port_id, volume_id). The stop method returns a boolean, is called after each polling and decides whether the blocking should stop. The delay is the time between each call of the poll method The timeout is the total time after which the blocker stops The caller callback method is not a generator anymore, instead it is just a method that takes the results of the poll method as input and it is called at each iteration. It remains optional. Typically, the caller may use it to advance a progress bar. The CycladesComputeClient, CycladesNetworkClient and CycladesBlockStorageClient have been updated so that they make use of the new method, but they retain the ability to call the Waiter methods for two more versions, due to backwards compatibility policies. The CLI has been adjusted to use the new mechanism.
