Tom Pantelis [Wed, 13 Jan 2016 21:17:28 +0000 (16:17 -0500)]
Implement change to voting with no leader

Implemented a special case where on a voting state change from
non-voting to voting, if there's no leader, it will try to elect a
leader in order to apply the change and progress.

This is to handle a use case where one has 2 geographically-separated
3-node clusters, one a primary and the other a backup such that if the
primary cluster is lost, the backup can take over. In this scenario,
there's a logical 6-node cluster where the primary sub-cluster is
configured as voting and the backup sub-cluster as non-voting such
that the primary cluster can  make progress without consensus from
the backup cluster while still replicating to the backup. On fail-over
to the backup, a request would be sent to a member of the backup
cluster to flip the voting states, ie make the backup sub-cluster
voting and the lost primary non-voting. However since the primary
majority cluster is lost, there would be no leader to apply, persist and
replicate the server config change.

Therefore, if the server processing the request is currently non-voting
and is to be changed to voting and there is no current leader, it will
try to elect itself the leader by applying the new server config change in
the RaftActorContext and sending an ElectionTimeout. If it's elected
leader, it persists and replicates the new server config. If no leader
change occurs within the election timeout period, it reverts the server
config change and tries to forward the change request to another server
with the same voting state change. In this manner, the intent is to elect
the newly voting server that has the most up to date log.

 - FutureSchema did not add the FutureSchemaPredicate instances to the
   postponedOperations list so they always timed out.

 - The waitForSchema method in BindingToNormalizedNodeCodec checked for

   occur just prior to adding a postponed operation to the list, in
   which case the operation may timeout if the new update contained the
   postponed criteria and another update didn't occur in time. To
   alleviate this, the sychronization was tighted up and runtime context
   is now stored in FutureSchema instead of BindingToNormalizedNodeCodec.

 - The runtimeContext field needs to be volatile.

onGlobalContextUpdated hadn't been initially notified yet.

ownership changes. This patch fixes that issue as follows,

- Consider the statistics that are collected using the DTL
  only as initialStatistics which are passed to the Strategy
  when it is created
- When Leadership changes clear all the strategies so that
  they get freshly created with the right initial statistic
- Modify the newOwner method on Strategy to
    - pass the currentOwner for the entity, for the current
      owner we decrease the ownership statistic
    - remove the statistics passed to it as it would no longer
      be required. Due to this removal we also get rid of all
      the CRUD which we had added to check if the passed in
      stats were actually greater than the local stats which
      anyway did not work.

Bug 4627: Fix premature RO tx cleanup

For the RO tx PhantomReference cleanup mechanism, modified
RemoteTransactionContextSupport to pass the front-end client
TransactionProxy instance as the referent to the
FinalizablePhantomReference. Previously we were passing the

a hard reference until the primary shard actor is obtained and thus may
be eligible for GC while the TransactionProxy is still in use.

The test cases in LeaderTest and CandidateTest have been failing
intermittently. A particular test in CandidateTest has recently started

The common denominator is that an initial message to an actor isn't

just created. This seems related to the use of ActorSelection in the raft

in the past and attempted to alleviate it by adding a verifyActorReady to
TestActorFactory to verify with retries that the actor can be obtained via
actorSelection.resolveOne. However it doesn't appear resolveOne works as
advertised or maybe a successful call doesn't mean a message will

would usually fail within 30 test runs. After the change it ran
successfully 400 times.
