  • Date: 2009-12-25 23:13:47 UTC
  • Revision ID: teddy@fukt.bsnet.se-20091225231347-gg9u9ru0wj0f24hh
More consistent terminology: Clients are no longer "invalid" - they
are "disabled".  All code and documentation changed to reflect this.

D=Bus API change: The "properties" argument was removed from the
"ClientAdded" signal on interface "se.bsnet.fukt.Mandos".  All code in
both "mandos" and "mandos-monitor" changed to reflect this.

* mandos: Replaced "with closing(F)" with simply "with F" in all
          places where F is a file object.
  (Client.still_valid): Removed.  All callers changed to look at
                        "Client.enabled" instead.
  (dbus_service_property): Check for unsupported signatures with the
                           "byte_arrays" option.
  (DBusObjectWithProperties.Set): - '' -
  (ClientHandler.handle): Use the reverse pipe to receive the
                          "Client.enabled" attribute instead of the
                          now-removed "Client.still_valid()" method.
  (ForkingMixInWithPipe): Renamed to "ForkingMixInWithPipes" (all
                          users changed).  Now also create a reverse
                          pipe for sending data to the child process.
  (ForkingMixInWithPipes.add_pipe): Now takes two pipe fd's as
                                    arguments.  All callers changed.
  (IPv6_TCPServer.handle_ipc): Take an additional "reply_fd" argument
                               (all callers changed).  Close the reply
                               pipe when the child data pipe is
                               closed.  New "GETATTR" IPC method; will
                               pickle client attribute and send it
                               over the reply pipe FD.
  (MandosDBusService.ClientAdded): Removed "properties" argument.  All
                                   emitters changed.
* mandos-clients.conf.xml (DESCRIPTION, OPTIONS): Use
                                                  "enabled/disabled"
                                                  terminology.
* mandos-ctl: Option "--is-valid" renamed to "--is-enabled".
* mandos-monitor: Enable user locale.  Try to log exceptions.
  (MandosClientPropertyCache.__init__): Removed "properties" argument.
                                        All callers changed.
  (UserInterface.add_new_client): Remove "properties" argument.  All
                                  callers changed.  Supply "logger"
                                  argument to MandosClientWidget().
  (UserInterface.add_client): New "logger" argument.  All callers
                              changed.
* mandos.xml (BUGS, SECURITY/CLIENTS): Use "enabled/disabled"
                                       terminology.
