syncdaemon: fix setting None as new master

2011-04-11T10:52:25+00:00

We checked for the event of a new master being adopted by:
- checking for state change in list of masters
- checking if our chosen master is a foreign one
and if these held, then wrote out the actually available master to config

However this was flaky: if
(1) native master changed
(2) there was already a foreign master adopted
(3) actually the master was not available
then we wrote out the None to config.

This could occur if:
- on syncd startup, native master just changes from None to the volume native
  [implies (1)]
- foreign master adopted from earlier run via config [implies (2)]
- actually foreign master was not available [implies (3)]

syncdaemon: give some refactoring to cascading code

2011-04-04T15:02:18+00:00

- expiry check of foreign volinfo moved back to GLUSTERServer,
  so that under the hood we can removexattr the expired ones;
  a nice side-effect is that we can use the same dict layout
  for foreign and native volinfo (ie., foreign needs no
  timeout field)
- get_volinfo() is renamed to get_sys_volinfo() and most of the logic
  is stripped off of it (what remained there is the check
  against foreign master ambiguity)
- volinfo transition logic is cut out to an almost purely functional
  static method (only impurity is the exeption raised upon
  forbidden volinfo change)
- ping renamed to keep-alive, as something called "ping" is
  not supposed to have payload (yeah, keep-alive is a bit fishy
  on this front too, but could not come up with better...)
