      Improve the blocking mechanism in kamaki clients · 80f20e72
      Stavros Sachtouris authored
      The "Waiter" class is now deprecated. A "wait" method is used
      instead. The new method is located at "kamaki.clients" and has
      this signature:
          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,
      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
      The CLI has been adjusted to use the new mechanism.

      Escape characters in CLI output methods · 5852db11
      Stavros Sachtouris authored
      Closes grnet/kamaki#32
      Kamaki CLI commands use some generic output methods to handle outputs.
      Generic output methods that escape control characters:
      - in kamaki.cli.utils: print_items, print_dict, print_list
      - in kamaki.cli.cmds: error
      Generic output methods that don't escape control characters:
      - in kamaki.cli.cmds: writeln, write
      The methods that don't escape control characters are used when the
      standard methods are not sufficient. For example, in "kamaki.cli.pithos"
      the "PithosAccount.print_objects" method adds decorative escape characters
      (i.e., bold, alignment), but has to escape the parts object and container
      names. To achieve this, escaping is handled in the method, and the output
      is printed with the "write" and "writeln" methods mentioned earlier.
      An encoding issue with kamaki.cli.errors.CLIError and the Exceptions extending it,
      is fixed. It is now ensured that the error message will always be in unicode.
      Also, fix flake8 errors on files affected by the above changes
